The invention belongs to the field of heat radiator assembly and particularly relates to a positioning mechanism based on heat radiating tubes. The positioning mechanism comprises a work table surface and a clamp connection unit, wherein the clamp connection unit comprises a plurality of guide strips in mutually parallel arrangement, gaps among the guide strips form a clamp connection opening arranged on the clamp connection unit, the guide strips are in arrangement in a mode that the arrangement direction of the guide strips is parallel to or intersected with the arrangement direction of the heat radiating tubes. When each guide strip arranged on the clamp connection unit is respectively in an external expansion state in the arrangement direction of the guide strips, the minimum gap of the clamp connection opening is greater than the heat radiating strip width in the flat straight state. When each guide strip arranged on the clamp connection unit is respectively in the gathering state, the minimum gap of the clamp connection opening is equal to the heat radiating strip width in the flat straight state. The positioning mechanism also comprises a motive power unit, when the motive power unit is positioned in an initial position, the clamp connection unit is positioned at a work platform part, and after the gathering action of the clamp connection unit is completed, the motive power unit acts and drives the clamp connection unit to move away from the work platform. The positioning mechanism has the advantages that the assembly positioning force is balanced, and the work efficiency is high.

The invention discloses an electric processing apparatus of a heating tape of a transmission line connector. The electric processing apparatus comprises a hot-line work tool, a shunt fastening device, and temperature detection devices that cooperate with each other. The hot-line work tool consists of an insulating rod and a walking robot capable of walking back and forth on a wire. The shunt fastening device includes two wire clamps connected by a shunt wire. At least two temperature detection devices are arranged at wires of transmission line contact points and include infrared sensors for detecting temperatures of the wire contact points; and the infrared sensors are connected with a temperature data collection unit with power supply based on the solar energy by a wireless transmission device. On the basis of combination of the hot-line work tool, the shunt fastening device, and the temperature detection devices, heating processing is carried out on the transmission line connector and cutting processing is carried out on foreign matters at the transmission line; the temperature monitoring function of the transmission line connector is realized; and the fusion operation of the different devices is realized.

The invention provides a coupling used between the rotating shaft of a motor and a spline connection shaft, which includes a left sleeve, a right sleeve, a shaft sleeve and a tapered sleeve. The outer surface of the left sleeve is welded with a The positioning key, the positioning key is clamped in the positioning groove on the motor rotating shaft, the shaft sleeve is connected with the left sleeve, and the inner side of the right sleeve is provided with an internal thread, which matches the external thread on the shaft sleeve, and the two ends of the sleeve are open , the inner diameter of the opening of one end of the shaft sleeve in contact with the left sleeve is smaller than the inner diameter of the opening of the other end, forming a conical through hole, and a tapered sleeve matching the conical through hole of the shaft sleeve is arranged inside the shaft sleeve. There is a shaft hole, and the end faces of the left sleeve and the right sleeve are provided with a tightening port. The inner diameter of the tightening port is larger than the inner diameter of the shaft hole and smaller than the maximum diameter of the tapered sleeve. Rotate the right sleeve to tighten the tapered sleeve through the tightening port. Squeeze into the bushing. The shaft coupling of the invention has a simple structure, applies force evenly to the spline connection shaft, and has good fixing effect.

The invention discloses a bridge arch rib hoisting and supporting bracket integrated construction device which comprises a base, a lifting frame is fixedly connected to the top end of the base, a first pneumatic push rod is fixedly connected to the inner wall of the lifting frame, a moving block is welded to the output end of the first pneumatic push rod, and a moving rod penetrates through the interior of the moving block; and first limiting grooves are formed in two ends of the moving rod and located in the inner wall of the lifting frame. According to the bridge arch rib hoisting and supporting bracket integrated construction device, by arranging a lifting column, in the lifting frame, the first pneumatic push rod works to drive the moving block to move, and the moving block drives the first lifting rod to move along the first limiting groove through the moving rod; the rotating angle of the first lifting rod is 60 degrees, the first lifting rod drives the second lifting column to move along a second limiting groove through the lifting column, the rotating angle of the second lifting rod is 60 degrees, and lifting operation of the lifting frame is achieved through relative movement of the first lifting rod and the second lifting rod.

The invention discloses a traction device for cable laying of a power supply company. The device comprises a main walking unit and two sets of auxiliary walking units hinged to the main walking unit.The two sets of auxiliary walking units are hinged to the corresponding side ends of the main walking unit through hinges respectively, the corresponding side ends of the two sets of auxiliary walkingunits are connected through bolts and nuts, and the main walking unit and the two sets of auxiliary walking units form a triangular mechanism used for crawling in a pipeline. Each of the main walkingunit and the two sets of auxiliary walking units comprises a base plate. The middle of the side face, away from the center of the triangular mechanism, of the base plate is hinged to one end of a shear fork telescopic mechanism. The device saves manpower, is convenient to use, is combined into a triangular structure, realizes crawling traction operation of cables of different specifications in pipelines of different sizes, can adapt to pipeline turning, can also be combined into a horizontal linear mechanism, can pull the cables on the ground, is wide in application range and adapts to different working conditions.

The invention discloses a cone locating and milling clamp for a valve body. The two sides of a work piece are located by a centre; a set screw is used to adjust, locate and lock the work piece; a pressure plate is used to press the work piece; and in this way, the work piece of the valve body is clamped conveniently and rapidly. Furthermore, the conical head part of the centre is designed as a cone; the centre is symmetrically provided with tangent plane bodies by milling from a small end to a large end along the direction of conical degree; and when the centre is pushed into locating holes at the two sides of the work piece, a gap is formed in the vertical direction, so that the height of the work piece can be adjusted conveniently, and the work piece can be located accurately. The cone locating and milling clamp for the valve body disclosed by the invention is reasonable in structural design, convenient and rapid to operate, and stable and reliable to clamp; and the two machined surfaces of the work piece meet the technical requirements such as symmetry, thus effectively ensuring the machining quality of the work piece.
