[0023] like Figure 5-9 As shown, the walkway support structure 3 includes: A mounting plate 1 31, wherein the mounting plate 1 31 is arranged longitudinally, and a plurality of mounting plates 2 33 arranged transversely are fixedly connected to one side of the mounting plate 1 31, and a support rod 1 34 runs through the plurality of mounting plates 2 33 and is rotatably connected to the plurality of mounting plates 2 33; A third mounting plate 35, wherein the third mounting plate 35 is longitudinally arranged on one side of the first mounting plate, and a plurality of receiving grooves 36 for receiving the second mounting plate 33 are provided on one side of the third mounting plate 35, and a second support rod 38 is arranged inside each of the receiving grooves 36, and the second support rod 38 is rotatably connected to the third mounting plate 35; A guide groove 2 37 is formed on the upper portion of the mounting plate 35, and the end of the support rod 1 34 is inserted into the guide groove 2 37. A guide groove 1 32 is formed on the bottom of one side of each of the plurality of mounting plates 2 33, and a plurality of support rods 2 38 are respectively disposed inside the plurality of guide grooves 1 32 and in contact with the mounting plate 2 33.

[0024] Both the mounting plate one 31 and the mounting plate three 35 are provided with a guide groove three 39, two friction plates two 313 are arranged inside the guide groove three 39, a mounting plate four 314 is arranged between the two friction plates two 313, one end of the mounting plate four 314 extends to the outside of the guide groove three 39 and is fixedly connected to the mounting plate five 316, and a friction plate one 310 is arranged on the top of the inner cavity of the guide groove three 39.

[0025] Specifically, a telescopic member is composed of two telescopic fences 2, and a walkway support structure 3 and a storage box 1 are arranged between the two telescopic fences 2. The walkway support structure 3 supports the staff to walk, and each walkway support structure 3 includes a mounting plate 1 31, a support rod 1 34 and a mounting plate 3 35, wherein one side of the mounting plate 1 31 is fixedly connected with a plurality of mounting plates 2 33, and one side of the mounting plate 3 35 is provided with a plurality of storage grooves 36 for storing the mounting plates 2 33, such as Figure 5 As shown, the distance between mounting plate one 31 and mounting plate three 35 can be adjusted. Pulling mounting plate one 31 and mounting plate three 35 apart can extend the length of the bearing plate formed by mounting plate one 31, mounting plate two 33 and mounting plate three 35, and the width of mounting plate three 35 and the distance between two mounting plates two 33 are small and will not affect the walking of the staff, and the gap between mounting plate three 35 and two mounting plates two 33 plays a drainage role, avoiding water accumulation on the tower crane walkway structure and affecting the safety of the staff.

[0026] The support rod 1 34 penetrates through the plurality of mounting plates 2 33 and is rotatably connected to the plurality of mounting plates 2 33. A guide groove 2 37 is provided at the top of one side of the mounting plate 35. At the same time, the support rod 1 34 is arranged inside the guide groove 2 37. The support rod 1 34 limits the plurality of mounting plates 2 33 and the mounting plates 3 35, so that the movement direction of the mounting plates 1 31 and the mounting plates 3 35 is restricted; and the support rod 2 38 arranged inside each storage slot 36 is rotatably connected to the mounting plate 3 35, and a guide groove is provided at the bottom of one side of the plurality of mounting plates 2 33. One 32 is used to support the second support rod 38, and the second support rod 38 is in contact with the second mounting plate 33, so that there are two upper and lower limit points between the thickened and more stable mounting plate one 31 and the mounting plate three 35, ensuring the stability of the cooperation between the mounting plate one 31 and the mounting plate three 35. Multiple mounting plates two 33 are fixedly connected on one side of the mounting plate one 31, and multiple storage grooves 36 are opened on one side of the mounting plate three 35 for storing multiple mounting plates two 33, which can ensure the stability of the adjustment of the length of the load-bearing plate and meet the stability and lightweight requirements of the use of the load-bearing plate.

[0027] A guide groove 39 is provided on both the mounting plate 1 31 and the mounting plate 3 35. Two friction plates 2 313 are arranged inside the guide groove 39. A mounting plate 4 314 is fixedly connected between the two friction plates 2 313. One end of the mounting plate 4 314 extends to the outside of the guide groove 39 and is fixedly connected to a mounting plate 5 316. When the two mounting plates 5 316 are pulled away from each other, the two mounting plates 5 316 drive the friction plates 2 313 to move inside the guide groove 39 through the mounting plate 4 314. The distance between the two mounting plates 5 316 is adjusted, and the mounting plate 5 316 is extended. Both ends of the retractable fence 2 are rotatably installed with the adjacent mounting plate five 316 through a pin shaft, so that the distance between the front and rear telescopic fences 2 can be adjusted, and the adjacent mounting plate one 31 and mounting plate three 35 in the two walkway support structures 3 are fixedly connected together, so the left and right length and front and back width of the tower crane walkway structure composed of multiple telescopic parts and multiple walkway support structures 3 can be adjusted to meet the tower crane walkway structure to adapt to different construction needs, reduce the time cost investment in the use of the tower crane walkway structure, and meet the needs of transporting equipment of different widths in emergency situations.

[0028] When the distance between the two telescopic fences 2 installed on both sides of a walkway support structure 3 is adjusted, since a friction plate 1 310 is provided at the top of the inner cavity of the guide groove 3 39, a threaded rod 312 is rotatably connected to the top of the friction plate 1 310, and the top of the threaded rod 312 passes through the mounting plate 1 31 or the mounting plate 3 35 and is threadedly connected to the mounting plate 1 31 or the mounting plate 3 35, the staff inserts the external hexagonal wrench into the internal hexagonal slot opened at the top of the threaded rod 312 and rotates it to rotate the threaded rod 312. When the friction plate 1 310 moves downward, the threaded rod 312 pushes the friction plate 1 310 at the bottom to move and contact the friction surfaces at the top of the two friction plates 2 313, thereby limiting the position of the friction plate 2 313, so that the mounting plate 5 316 installed by the two friction plates 2 313 through the mounting plate 4 314 is limited, and the position of the telescopic fence 2 is limited. After the friction plate 1 310 moves downward to limit the friction plate 2 313, the top end of the threaded rod 312 is located at the bottom of the top surface of the mounting plate 1 31 or the mounting plate 3 35, and the threaded rod 312 will not affect the walking of the staff.

[0029] The two mounting cross bars 41 in the transmission structure 4 are respectively mounted at both ends of the tower crane walkway structure, and both ends of the two mounting cross bars 41 are rotatably connected to the adjacent mounting plates 5 316, and the mounting cross bars 41 are composed of two telescopic rods 4101 and two support rods 4102, and the outer walls of the two telescopic rods 4101 are fixedly connected to each other, such as Figure 3 As shown, the extended ends of the two telescopic rods 4101 are respectively fixedly connected to the two supporting rods 4102. Since the telescopic rods 4101 can be extended and retracted, the installation of the cross bar 41 meets the position adjustment requirements between the two mounting plates 5 316 installed at both ends, and the winding rack 42 is fixedly sleeved on the outer side of the supporting rod 4102. A steel wire rope 43 is fixedly connected between the two winding racks 42 that are symmetrically arranged on the left and right. A clamping plate 48 is fixedly connected between the two steel wire ropes 43. The clamping plate 48 is arranged on the top of the tower crane walkway structure under the support of the two steel wire ropes 43, which will not affect the normal walking of the staff. A clamping plate 2 49 is disposed on the top of the clamping plate 1 48. The bottom ends of the two support rods 6 410 fixedly connected to the clamping plate 2 49 both penetrate the clamping plate 1 48 and are fixedly connected to a spring-type telescopic rod 411. Figure 4As shown, a hook 412 for hanging objects is fixedly connected to the bottom end of the spring-type telescopic rod 411, and the initial position of the clamping plate 48 is the end of the tower crane walkway structure away from the tower crane and close to the building. The staff on the building use two hooks 412 to hang lighter objects, such as food, clothes, drinking water, etc., and the two mounting cross bars 41 are both installed with sprocket transmission assemblies. The staff on the tower crane operates the handwheel 46 in the adjacent sprocket transmission assembly. Two sprockets 44 are installed inside the chain 45 in the sprocket transmission assembly. The two sprockets 44 are fixedly sleeved on the mounting cross bar 41 and the outer side of the support rod 5 47, and the support rod 5 47 is rotatably connected to an adjacent mounting plate five 316. Therefore, the rotation of the operating hand wheel 46 will drive the support rod five 47 to rotate. Under the action of the sprocket transmission assembly, the mounting cross bar 41 rotates. The rotating mounting cross bar 41 drives the winding frame 42 to rotate and wind up the wire rope 43. The wire rope 43 drives the clamping plate one 48 to move toward the tower crane. The clamping plate one 48 drives the spring-type telescopic rod 411 and the hook 412 to move toward the tower crane, so as to transport the items to the vicinity of the staff on the tower crane, reduce the frequency of the staff walking on the tower crane walkway structure, reduce the occurrence of accidents, and meet the needs of people with acrophobia to transport supplies to the staff on the tower crane.

[0030] In addition, the support rod 6 410 has a certain length, and the clamping plate 2 49 can be moved up and there is a certain space between the clamping plate 1 48. The spring-type telescopic rod 411 is pushed up as a whole to move the clamping plate 2 49 up and separate from the clamping plate 1 48, and then one end of the tarpaulin is placed between the clamping plate 2 49 and the clamping plate 1 48, and then the spring-type telescopic rod 411 is lowered to make the clamping plate 2 49 clamp one end of the tarpaulin, and then the hook 412 is used to hang the heavy object. The weight of the heavy object acts on the tarpaulin through the hook 412, the spring-type telescopic rod 411 and the clamping plate 2 49, so that one end of the tarpaulin can be clamped. Then the staff on the tower crane side operates the hand wheel 46 to rotate, and under the action of the sprocket transmission assembly, one end of the tarpaulin is pulled toward the tower crane, and the tarpaulin is set up on the top of the tower crane walkway structure to meet the needs of working in rainy days.

[0031] like Figure 2As shown, a plurality of mounting rods 14 are provided on both sides of the storage box 1, and the plurality of mounting rods 14 are respectively fixedly connected to a plurality of mounting plates 5 316 and a plurality of retractable fence 2 rotation mounting parts, and a support bearing 13 for drag reduction is fixedly sleeved on the outer side of the mounting rod 14. A U-shaped piece 12 is fixedly connected on both sides of the storage box 1, and the inner cavity of the U-shaped piece 12 has a certain length in the front-to-back and upward directions and in the left-to-right and upward directions. The mounting rod 14 also has a certain length in the front-to-back direction. After the distance between the two symmetrically arranged retractable fences 2 is adjusted, the U-shaped piece 12 can still be sleeved on the outer side of part of the support bearing 13, so that the two sides of the storage box 1 are fixedly connected. The connected U-shaped piece 12 is supported by multiple rotatable support bearings 13, which reduces the resistance of the storage box 1 to the movement inside the tower crane walkway structure, and the staff places items of a certain weight inside the storage box 1; two lifting rings 11 are fixedly connected to the top of the storage box 1, and after the hook 412 is pulled down, one end passes through the adjacent lifting ring 11, and then the staff on the tower crane side operates the hand wheel 46 to rotate, and under the action of the sprocket transmission assembly, the storage box 1 is pulled toward the tower crane to transport heavier items on the tower crane walkway structure, avoiding the situation where the staff manually carry heavy items and then walk on the tower crane walkway structure, thereby reducing safety hazards.

[0032] In addition, such as Figure 4 As shown, the spring-type telescopic rod 411 can be telescoped to meet the need of the hook 412 to move downward, so that the hook 412 can hang different objects.

[0033] In addition, such as Fig. 9 and Fig.10 As shown, the friction plate 1 310 is slidably connected to two support rods 311, and the support rods 311 are fixedly installed with the mounting plate 1 31 or the mounting plate 35. The two support rods 311 limit the up and down movement of the friction plate 1 310 to ensure the stability of the vertical movement of the friction plate 1 310 and the coordination with the friction plate 2 313.

[0034] In addition, such as Fig. 9 and Fig.11 As shown, a plurality of drag reduction rods 315 are arranged inside the guide groove three 39 , and the drag reduction rods 315 are installed together with the mounting plate one 31 or the mounting plate three 35 .

[0035] In addition, such as Figure 1 and Figure 3 As shown, the two ends of the steel wire rope 43 are respectively wrapped around the outside of the two winding frames 42 to meet the needs of adjusting the length of the tower crane walkway structure.
