Sealed waterproof jacking mechanism of movable bearing seat

Abstract

The invention discloses a sealed waterproof jacking mechanism of a movable bearing seat. The sealed waterproof jacking mechanism comprises a working roller seat, a sliding rail seat. a sliding block, a protection cover, a locking block and a power source. The movable bearing seat is arranged at one end of the working roller seat. The sliding rail seat is arranged below the working roller seat, and a sliding groove is formed below the sliding rail seat. The sliding block is arranged below the sliding rail seat and connected with the sliding groove in a sliding manner, and the movable bearing seat is installed on the sliding block. The protection cover is arranged around the sliding rail seat and comprises a front baffle, a rear baffle, a left baffle, a right baffle and a lower baffle, and a hollow cavity is defined among the front baffle, the rear baffle, the left baffle, the right baffle, the lower baffle and the sliding rail seat. The locking block is inserted between the sliding block and the sliding rail seat, and the sliding block and the sliding rail seat are locked by pushing the locking block through slope extrusion fit. The power source is provided with a push rod, and the push rod is located in the cavity of the protection cover. The push rod acts on the locking block and the sliding block so as to drive the locking block and the sliding block to move forwards along the sliding rail seat together and to be kept at the preset position. The protection cover not only plays a waterproof role on the push rod, but also plays a waterproof role on the slide rail seat.

Description

technical field [0001] The invention relates to the field of derusting treatment of steel plates and wires, in particular to a sealed and waterproof jacking mechanism for a movable bearing seat. Background technique [0002] At present, there are two ways to remove rust on the surface of the steel plate, pickling and physical grinding. The pickling method causes serious environmental pollution and does not meet the long-term requirements of environmental protection; physical grinding generally uses scale-breaking rollers to polish the steel plate. To improve work efficiency, when the scale breaking roller is worn out and cannot be used, it needs to be replaced. If the scale breaking roller needs to be replaced, the descaling device must be able to disassemble and install the scale breaking roller, that is, it must have a movable relative frame. The connection mechanism, and the connection mechanism will inevitably wear out when the scale-breaking roller rotates at a high spe...

Problems solved by technology

[0002]At present, there are two ways to remove rust on the surface of the steel plate, pickling and physical grinding. The pickling method seriously pollutes the environment and does not meet the long-term requirements of environmental protection ;Physical grinding brushes generally use scale-breaking rollers to grind steel plates. In order to improve work efficiency, when the scale-breaking rollers are worn out to the point of being unusable, the scaling-breaking rollers need to be replaced. If the scale-breaking rollers need to be replaced, the descaling device is required to be disassembled. To install the scale-breaking roller, there must be a movable connection mechanism relative to the frame, and the connection mechanism will inevitably wear out when the scale-breaking roller rotates at high speed, which makes the connecting mechanism originally designed for disassembling and assembling the scale-breaking roller. Major hidden dangers of safety accidents

[0003] The Chinese invention patent of CN201910947005.8 discloses an automatic scale-breaking rod replacement mechanism for a steel plate surface derusting device, including an upper beam, a general working beam, a bearing seat and Scale breaking roller, the working beam moves up and down relative to the upper beam, and the bearing seats are arranged at both ends of the working beam; the upper beam drives the working beam to move horizontally; The working beam moves left and right; each of the two bearing seats is equipped with an elastic auxiliary mechanism, including a base, which drives the internal gear to rotate through a screw, and a gear shaft is meshed in the internal gear, and an external gear is fixed at both ends of the scale breaking roller. The exposed end of the shaft is retracted inwardly relative to the front end of the internal gear, leaving a gap; when the roller is installed, the internal gear rotates and approaches the external gear, and when the internal and external gears are not meshed, the internal gear retreats under the pressure of the external gear, and when the teeth of the external gear When aligning the tooth clearance of the internal gear, the internal gear pushes back under the action of the elastic force to make the external gear enter the space and mesh with the internal gear; when the mechanism is working, the oil cylinder always pushes the slider and withstands the bearing seat, so that the bearing seat If it is not disengaged from the scale breaking roller, it may cause the oil cylinder to sink for a long time, and the bearing seat and the scale breaking roller will not cooperate well, making it difficult to work and even accidents; and because the scale breaking roller rotates at high speed, the vibration If it is too large, the slider will wear out after a long time, and finally the slider will vibrate, which will pose a safety hazard; furthermore, the scale-breaking roller rotates at high speed during work, in order to timely remove the oxide scale and The debris that is lost by itself needs to be cleaned in time by spraying water. Therefore, except for the exposed bearing seat and scale breaking roller, other parts need to be waterproofed to avoid rust or water ingress
