Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of tower crane walkway panels, and in particular to a telescopic tower crane jib suspension bridge walkway panel. Background Technology
[0002] The function of a tower crane is to bear the upper load transmitted by the boom rope and the counterweight boom rope, and to transmit it directly to the tower structure through the turntable via structural components such as the slewing tower, turntable, and bearing. Usually, the suspension bridge at the jib of the tower crane is equipped with walkways, also known as scaffold boards, which are laid on scaffolding and working frames to facilitate workers to walk on them, transfer materials, and carry out construction work. They are a type of temporary building material used for turnover.
[0003] The existing walkways at the jib of tower cranes are mostly made of bridge deck panels. They are laid out, cut, and welded according to the site conditions and require the use of steel wire ropes for tying. If other teams arbitrarily remove the steel wire ropes, it can easily cause safety hazards. Moreover, the length of the walkway panels is fixed and cannot be flexibly adjusted for use. Utility Model Content
[0004] To address the aforementioned shortcomings in the existing technology, this utility model provides a retractable walkway for the jib of a tower crane. The purpose is to solve the problems of existing walkways for the jib of tower cranes, which mostly use jib plates, which are laid out, cut and welded according to the site conditions, and require steel wire ropes for connection. If other teams arbitrarily remove the steel wire ropes, it can easily cause safety hazards. Moreover, the length of the walkway is fixed and cannot be flexibly adjusted.
[0005] To achieve the aforementioned objectives, the technical solution adopted by this utility model is as follows:
[0006] A retractable tower crane jib suspension bridge walkway includes a fixed plate and a movable plate, the movable plate being slidably disposed with respect to the fixed plate. The fixed plate includes channel steel, a first patterned steel plate, a first mounting plate, and a first reinforcing plate. There are two channel steels symmetrically arranged. The first patterned steel plate is fixedly welded to the two channel steels. The first reinforcing plate is fixedly welded to the side of the two channel steels away from the first patterned steel plate. The fixed plate also includes two square steels, a second patterned steel plate, a second reinforcing plate, and a second mounting plate. There are two square steels. The second patterned steel plate is fixedly welded to the two square steels. The second reinforcing plate is fixedly welded between the two square steels. There are two second mounting plates fixedly welded to both ends of the two square steels. Both the channel steel and the square steel have several evenly distributed connecting holes, allowing for fixed connection between the channel steel and the square steel via the connecting holes and bolts.
[0007] Both the first mounting plate and the second mounting plate have mounting holes.
[0008] Furthermore, both of the square steel bars are provided with sliding components at their bottoms.
[0009] Furthermore, the sliding assembly includes a frame fixedly welded to a square steel, within which a plurality of evenly distributed rollers are rotatably connected.
[0010] The beneficial effects of this utility model are as follows:
[0011] This utility model discloses a telescopic scaffolding board for the jib of a tower crane. The length of the fixed board and the movable board can be flexibly adjusted. Compared with the jib board, the telescopic movable scaffolding board does not require the use of steel wire ropes for tying, making the main structure easier to construct. It also avoids the safety risks caused by other teams arbitrarily removing steel wire ropes. Attached Figure Description

[0021] like Figures 1 to 2 As shown, a telescopic tower crane boom suspension bridge walkway includes a fixed plate 1 and a movable plate 2.
[0022] The movable plate 2 and the fixed plate 1 are slidably set.
[0023] The fixing plate 1 includes a channel steel 3, a first patterned steel plate 4, a first mounting plate 5, and a first reinforcing plate 6. There are two channel steels 3, which are symmetrically arranged. The first patterned steel plate 4 is fixedly welded to the two channel steels 3, and the first reinforcing plate 6 is fixedly welded to the side of the two channel steels 3 away from the first patterned steel plate 4.
[0024] The fixing plate 1 includes square steel 7, second patterned steel plate 8, second reinforcing plate 9, and second mounting plate 21. There are two square steel 7. The second patterned steel plate 8 is fixedly welded to the two square steel 7. The second reinforcing plate 9 is fixedly welded in the middle of the two square steel. There are two second mounting plates 21. The two second mounting plates 21 are fixedly welded to both ends of the two square steel 7.
[0025] Both the channel steel 3 and the square steel 7 are provided with several evenly distributed connecting holes 10, and the channel steel 3 and the square steel 7 can be fixedly connected by connecting holes 10 and bolts.
[0026] When the walkway slab is being lifted, the movable plate 2 is inserted into the fixed plate 1, and bolts are inserted into the connecting holes 10 to fix the movable plate 2 and the fixed plate 1, and then the walkway slab is lifted.
[0027] Mounting holes 11 are provided on both the first mounting plate 5 and the second mounting plate 21.
[0028] After being lifted to the installation position, remove the connecting bolts between the movable plate 2 and the fixed plate 1, pull the movable plate 2, and then insert the bolts into the connecting hole 10 to fix the movable plate 2 and the fixed plate 1. Install the first mounting plate 5 and the second mounting plate 21 in the installation position through the bolts and the mounting hole 11 respectively. Example
[0029] like Figures 3 to 4 As shown, a telescopic tower crane boom suspension bridge walkway includes a fixed plate 1 and a movable plate 2.
