Embodiment 1

[0023] Such as figure 1 The direct-buried cable pay-off vehicle is equipped with a constant tension self-pressing straight pay-off device, which aims to provide a pay-off device suitable for the requirements of direct-buried cables. This pay-off device has two purposes, one is constant tension The second is to straighten the cable. Based on the above purpose, the device is provided with two functional units, namely a constant tension auxiliary unit and a straightening and pulling unit.

[0024] This device is used in conjunction with the pay-off car. Such as figure 1 and figure 2 As shown, the device takes the bracket 1 as the base structure, and two side plates 2 are installed on the bracket 1, and the retention groove 201 provided on the side plate 2 is used to cooperate with the movable card 5 to install the wire roller 6. During use, the wire roller 6 of the cable is placed on the retention groove 201 by a lifting device, and through the cooperation of the retention g...

Abstract

The invention provides a constant-tension and autonomous straightening paying-off device attached to a direct-buried cable paying-off vehicle. The problems that an existing paying-off vehicle is largein paying-off operation difficulty and unsuitable for direct-buried laying are effectively solved. The constant-tension and autonomous straightening paying-off device comprises a bracket, two side plates are mounted on the bracket, a line roller is mounted on the side plates, two guiding rods and a reciprocating lead screw are mounted on the two side plates, an engine of the paying-off vehicle isconnected with a rotating wheel of the reciprocating lead screw through a transmission belt, the guiding rods and the reciprocating lead screw are used for supporting and mounting a paying-off straightening device, a motor is mounted on the side wall of a rack of the paying-off straightening device, two pairs of longitudinal pressing wheels and transverse pressing wheels which are mounted correspondingly are mounted inside the rack, and the motor is connected with the longitudinal pressing wheels in a belt transmission mode. The constant-tension and autonomous straightening paying-off devicehas the beneficial effects that a reciprocating moving device and a bidirectional pressing wheel paying-off device are arranged in one device, and the purpose of constant-tension and straightening paying-off can be achieved through one device.

Description

technical field [0001] The invention relates to the field of cable laying equipment, specifically a direct-buried cable pay-off vehicle with a constant tension self-pressing straight pay-off device. Background technique [0002] The direct buried cable is in accordance with the requirements of the specification. After the direct buried cable trench is dug, a sand cushion is laid on the bottom of the trench, and the sundries in the trench are removed, and then the cable is laid. A cable laying method in which a brick or concrete slab is covered on the cable to protect the cable and then backfilled. The requirements for the laying of direct buried cables are that the cables must ensure no longitudinal bending and constant tension during the laying-off process. The laying of cables usually uses pay-off carts and pay-off racks. The principle of putting down the car and pay-off frame adopted in the existing market makes the wire in the wire reel pulled out at a constant speed w...
