The hydraulic telescoping member 507 of the present embodiment is used to drive two hydraulic motors 503 toward and away from each other. The present embodiment is provided with a road wheel 505 on an output shaft 504 of each hydraulic motor 503, the road wheel 505 including a wheel body 5051 coaxially connected with the output shaft 504 of the hydraulic motor 503, gear teeth 5052 being uniformly formed on an outer circumferential surface of the wheel body 5051 along a circumferential direction thereof, and a backlash 5053 being formed between the adjacent gear teeth 5052. As shown in fig. 8, when the hydraulic telescoping member 507 drives the two hydraulic motors 503 away from each other to a predetermined position, the gear teeth 5052 of the traveling wheel 505 are drivingly connected to the corresponding side creeper rod 603. As shown in fig. 9, when the hydraulic telescopic members 507 drive the two hydraulic motors 503 to approach each other to a predetermined position, the travelling wheels 505 move towards the corresponding crawling rods 603, so that the crawling rods 603 penetrate into the gaps 5053, and further the gear teeth 5052 of the travelling wheels 505 and the crawling rods 603 on the corresponding sides are locked, i.e. when the travelling wheels 505 are driven to rotate, the travelling wheels are limited by the crawling rods 603 on the adjacent positions, so that the travelling wheels cannot rotate, thus the situation that the vertical guide rail 600 and the self-locking type hydraulic travelling unit 500 perform relative movement can be fully avoided, the connection integrity of the vertical guide rail 600 and the self-locking type hydraulic travelling unit 500 is improved, the relative positions of the vertical guide rail 600, the self-locking type hydraulic travelling unit 500 and the pier body are stable, and various severe environments are further adapted, and the self-locking type self-travelling lifting platform 700 is stopped at the predetermined position. Because the self-locking self-walking lifting platform 700 is lifted by the walking wheel 505 rotating on the crawling ladder, and further the self-locking self-walking lifting platform 700 is lifted in a stepless (non-stop) manner, the self-locking hydraulic walking unit 500 can be stopped at any position of the pier body by locking the walking wheel 505 on the guide rail body 601 according to the situation. In this embodiment, a plurality of tube passing holes 510 are formed on the mounting base 501, and the hydraulic tube of the hydraulic motor 503 is connected to the hydraulic pump station 1100 through the tube passing holes 510.
As a preferred embodiment of the present invention, in order to increase the strength of the travelling wheel 505, so that the travelling wheel 505 can bear a larger external force when locking the vertical guide rail 600, as shown in fig. 10, the thickness of the travelling wheel 505 increases gradually inwards along the radial direction, so that not only can the teeth 5052 bear a larger torsion force when the travelling wheel 505 rotates and travels on the vertical guide rail 600, but also the contact area of the travelling wheel 505 and the crawling rod 603 is increased when the travelling wheel 505 locks the crawling rod 603, and the surface where the gaps 5053 are positioned provides a larger supporting surface, so that the locking of the travelling wheel 505 on the vertical guide rail 600 is more repeated; in addition, the travelling wheel 505 adopts the arrangement, the self strength of the travelling wheel is correspondingly enhanced, and the service life of the travelling wheel is prolonged. In order to move the two hydraulic motors 503 in a predetermined direction by the driving of the hydraulic telescopic members 507 in this embodiment, as shown in fig. 5, a slider 506 is mounted on each hydraulic motor 503, and a chute 502 is formed on the mount 501, and the chute 502 extends in the lateral direction of the vertical rail 600. The sliding block 506 of the present embodiment is slidably mounted on the mounting base 501 through the sliding groove 502, and the mounting base 501 is detachably connected to the mounting frame 701. In order to improve the connection performance between the hydraulic expansion member 507 and the vertical rail 600 in this embodiment, specifically, as shown in fig. 6, a guide block 508 is mounted on the hydraulic expansion member 507, a guide groove 509 is configured at one end of the guide block 508 facing the vertical rail 600, a guide bar 604 extending in the vertical direction is configured on the rail body 601, and the guide block 508 is slidably connected with the guide bar 604 through the guide groove 509.
In order to avoid that the walking wheel 505 is subjected to a larger everting external force, that is, because the gravity center of the assembling frame 701 is not located at the walking wheel 505, the assembling frame 701 has an everting force on the vertical guide rail 600 in a non-vertical direction through the walking wheel 505, and in order to counteract the external force and prevent the walking wheel 505 from being damaged, as shown in fig. 17, guiding edges 605 are respectively configured at two sides of a connecting part of the guide rail body 601 and the pier body, two guiding plates 511 are configured on the mounting seat 501, the guiding plates 511 are assembled in gaps between the corresponding guiding edges 605 and the pier body, so that the guiding plates 511 are subjected to the everting force, and the guiding plates 511 and the guiding edges 605 are matched, thereby playing a guiding role of the mounting seat 501 and ensuring the self-locking type self-walking lifting platform 700 to move in the vertical direction.
