The lateral guide roller set 250 and the laterally adjustable guide roller set 260 differ in that: the bracket of the lateral guide roller set 250 is movably inserted into one side of the slider body 210, and the lateral adjustable guide roller set bracket 261 of the lateral adjustable guide roller set 260 is fixedly installed on the other side of the slider body 210 by the lateral guide roller set adjusting bolt 263. Therefore, the structure of the lateral guide roller set 250 will not be described in detail herein.
The principle of adjusting the clearance between the slider assembly 200 and the upright post assembly 100 is as follows:
due to manufacturing tolerance issues with the mast assembly 100 and installation issues with the slider assembly 200, adjustment is required after the slider assembly 200 is inserted from the upper end of the mast assembly 100. The adjustment of the forward guide wheel group 230 is realized by adjusting the forward guide wheel adjusting bolt 235 to push the forward guide wheel 232 to tightly press the opening flanging of the upright post body. The forward adjustable guide wheel set 240 directly pushes the forward adjustable guide wheel shaft 241 to drive the forward adjustable guide wheel to press the forward contact surface of the upright post body by adjusting the forward adjustable guide wheel set adjusting bolt 244, so as to control the forward gap. The lateral adjustable guide wheel set 260 drives the lateral adjustable guide wheel to press the lateral contact surface of the upright body by adjusting the depth of the lateral guide wheel set adjusting bolt 263 screwed into the inclined wedge block 264, so as to control the lateral clearance. At this point, the installation adjustment is completed.
As shown in fig. 6, the slider assembly 200 is further provided with a slider self-locking device for realizing safe falling prevention of the slider assembly 200. The slider self-locking device in this embodiment is a dual safety protection device, and includes a weightlessness-force breaker 270 and an anti-falling protection electromagnetic card 280. The back and the side of the upright post body are also provided with a plurality of upright post gaps. The weightless force breaker switch 270 is installed on the top of the slider assembly 200, such as on the side of the traction chain set 220, and is used to lock the slider assembly 200 when the slider assembly 200 loses traction force, so as to prevent the slider assembly 200 from dropping. The zero-gravity switch 270 of this embodiment may also be replaced by a dead-force self-locking switch. The anti-falling protection electromagnetic card 280 is installed at the waist of the slider body 210 for power-off protection.
The traction chain set 220 of the slider assembly 200 presses the weightlessness-force breaker 270 under the action of traction force, so that the slider assembly 200 can be freely lifted and lowered in an unlocked state. When the slider assembly 200 loses traction (e.g., the chain breaks, power is cut off, etc.), the traction chain set 220 releases the gravity-loss power-off switch 270 under the action of gravity, so that the slider assembly 200 is locked in a locked state and prevented from falling. The anti-falling protection electromagnetic card 280 retracts the clamping tongue when being powered on, the clamping tongue is freely ejected out under the action of spring force when being powered off, and the clamping tongue is locked on the upright column notch of the upright column body, so that the power-off anti-falling function is realized. The system can greatly improve the safe and reliable operation of the system under the dual functions of the dual safety protection devices.
The traction device 400 is arranged at the top end of the upright post assembly 100 and is connected with the traction chain group 220 through a chain 410 to realize traction driving of the slide block assembly 200, so that the slide block assembly can be lifted and lowered to run up and down. During operation, the slider assembly 200 may dissipate the force exerted by the consumable load on the mast assembly 100. As shown in fig. 7, the chain 410 is threaded through the drag chain axle, and the drag chain set 220 is threaded through the chain 410 and then tightened to the drag chain axle half shoe. In this embodiment, the chain 410 may be replaced with a wire 420 or a hydraulic cylinder 430 to achieve the same operation.
When the system of the embodiment works, the sliding block assembly 200 is lifted by rolling the eight forward guide wheels in total through the forward guide wheel set 230 and the forward adjustable guide wheel set 240 in front and back when the front face bears, the front face of the upright post body bears the stress and deforms little, and the upright post body can bear the working load and work stably. When the slider assembly 200 bears on the side, the left and right sides roll through eight lateral guide wheel sets of lateral guide wheel set 250 and lateral adjustable guide wheel set 260 to complete the lifting, and the opening flanging of the stand column body is pressed through the lateral force of the tapered roller bearing 233 increasing the stand column body, so as to prevent the stand column body from deforming and opening due to the force, realize the stable work of bearing the lateral working load, and solve the situation that the stand column deforms and opens due to the working load borne by the side surface of the traditional stand column and cannot normally run.
The forward guide wheel 232, the forward adjustable guide wheel, the lateral guide wheel and the lateral adjustable guide wheel used in the embodiment are all bearing rollers, and compared with a common vehicle lifting machine which uses wear-resistant plastic as a sliding block to bear a sliding friction part, the bearing rollers slide more smoothly and are more durable.
Compared with the traditional upright column sliding block structure, the upright column and the sliding block system thereof can better realize front and side bearing, have novel and simple structure and have good operation stability, durability and safety.
