Meanwhile, with continued reference to fig. 3, a corresponding anti-slip strip 211 may be disposed on the top surface of the bearing plate 21, so as to improve the anti-slip performance of the bearing plate 21, and avoid slipping when a constructor stands on the bearing plate 21 to freely move. In addition, the bearing plate 21 may adopt a net plate with a net structure, so as to reduce the weight of the bearing plate 21 as much as possible, and facilitate the subsequent adjustment of the position of the bearing plate 21 in the vertical direction. As a preferred solution, the bearing plate 21 of each platform unit 201 may be slidably disposed on the upright 101, so that the bearing plate 21 of each platform unit 201 is integrally connected with the upright 101, and the bearing plate 21 may also slide up and down relative to the upright 101, so as to further improve the stability of the bearing plate 21.

The driving component 31 is used for driving the first bevel gears 322 of the two lifting units 32 to rotate simultaneously, and when the first bevel gears 322 of the two lifting units 32 rotate, based on the principle of screw transmission, the circular motion of the first bevel gears 322 in the horizontal direction is converted into the linear motion of the lifting screw 323 in the vertical direction, and then the lifting screw 323 of the two lifting units 32 pushes the bearing plate 21 to drive the bearing plate 21 to move in the vertical direction.
Specifically, in order to realize that one driving component 31 drives the first bevel gears 322 of two lifting units 32 to rotate at the same time, with continued reference to fig. 4, the driving component 31 of the present embodiment includes a connecting plate 311, a bearing block 312, a driving shaft 313, a rotating handle 314, and second bevel gears 315 in one-to-one correspondence with the first bevel gears 322, that is, one first bevel gear 322 corresponds to one second bevel gear 315. At this time, the fixed cylinders 321 of the two lifting units 32 are connected by a connecting plate 311 which is horizontally arranged, a bearing seat 312 is arranged at the top of the connecting plate 311, a driving shaft 313 is horizontally arranged along the width direction of the supporting plate 11 of the supporting member 1, the driving shaft 313 is rotatably arranged on the connecting plate 311 by the bearing seat 312, a rotating handle 314 is arranged at one end of the driving shaft 313 facing the standard section 100 of the tower crane, a second bevel gear 315 is sleeved on the outer wall of the driving shaft 313 and coaxially rotates with the driving shaft 313, and the second bevel gear 315 is meshed with the first bevel gear 322.

Meanwhile, through setting the rotating handle 314 at one end of the driving shaft 313 facing the tower crane standard section 100, when the position of the bearing plate 21 in the vertical direction needs to be adjusted, only a constructor is required to stand in a channel inside the tower crane standard section 100 to operate the rotating handle 314, and the rotating handle is simple and convenient to operate and can effectively ensure the personal safety of the constructor.
In addition, with continued reference to fig. 4, each lifting unit 32 of the present embodiment further includes two guide pieces 324, the two guide pieces 324 are respectively disposed at both sides of the fixed cylinder 321 along the length direction of the support plate 11 of the support member 1, at this time, the guide pieces 324 are of a telescopic structure, the fixed ends of the guide pieces 324 are connected with the top of the support plate 11 of the support member 1, the telescopic ends of the guide pieces 324 are connected with the bottom of the carrier plate 21 of the carrier member 2, the carrier plate 21 is supported from the periphery of the bottom of the carrier plate 21 by the guide pieces 324 of the two lifting units 32, and the movement of the carrier plate 21 in the vertical direction is guided and restrained to improve the stability of the carrier plate 21 during the reciprocating movement in the vertical direction.

When the lifting screw 323 drives the carrier plate 21 to reciprocate along the vertical direction, the telescopic column 3242 can slide freely inside the fixed column 3241, so that a good guiding effect is achieved by the guide piece 324, and meanwhile, a certain buffering effect can be achieved through the additionally arranged buffer spring 3243, so that the stability of the carrier plate 21 during reciprocating along the vertical direction is further improved.
In the present embodiment, the traction unit 4 is used to reduce the risk of the carrier plate 21 falling down during actual use, so as to further improve the reliability of each platform unit 201.

In this way, assuming that the carrying plate 21 is at the lowest position and the traction rope 41 is in a tensioning state in the initial state, when the carrying plate 21 moves upwards under the action of the linear driving member 3, the carrying plate 21 drives the rack 46 to synchronously move upwards, the rack 46 which moves upwards drives the gear 45 to rotate, and then the rotating shaft 44 is driven by the gear 45 to rotate, at the moment, the rotating shaft 44 drives the wire twisting disc 43 to rotate so that the traction rope 41 is continuously wound on the wire twisting disc 43, wire collection is achieved, and therefore the traction rope 41 between the wire twisting disc 43 and the protective fence 22 is always kept in the tensioning state so as to pull the carrying member 2, and the risk of falling of the carrying member 2 is reduced, otherwise, when the carrying plate 21 moves downwards under the action of the linear driving member 3, the carrying plate 21 drives the rack 46 to synchronously move downwards, the rack 46 which moves downwards drives the gear 45 to reversely rotate, at the moment, the rotating shaft 44 reversely rotates under the action of the gear 45, and then the rotating shaft 44 drives the wire twisting disc 43 to reversely rotate so that the wire twisting disc 43 is continuously wound on the wire twisting disc 43, and the traction rope 41 between the wire twisting disc 43 and the protective fence 22 is always in the tensioning state.
Therefore, in this embodiment, the traction units 4 are additionally arranged on each platform unit 201, and the tensioning mechanism for winding and unwinding the traction ropes 41 according to the movement of the bearing plate 21 is arranged, so that the traction ropes 41 are always in a tensioning state in the process of reciprocating movement of the bearing plate 21 along the vertical direction without additionally arranging an additional driving device, the bearing member 2 is reliably pulled by the traction ropes 41 in the tensioning state, the reliability of each platform unit 201 in the actual use process is effectively improved, and reliable safety guarantee is provided for constructors who implement corresponding construction operations.
It should be noted that, at least one traction unit 4 of each platform unit 201 is provided, and preferably, in this embodiment, the number of traction units 4 of each platform unit 201 is two, and the two traction units 4 are sequentially disposed on two sides of the bearing plate 21 of the bearing member 2 along the length direction of the bearing plate 21 of the bearing member 2, so as to further improve the reliability of the platform unit 201 when in use, and at this time, the fixed pulleys 42 and the rotating shafts 44 of the same traction unit 4 are disposed on the same side of the same upright post 101 of the tower crane standard section 100. Of course, in actual implementation, more traction units 4 may be provided as needed, and the number and positions of the traction units 4 are not particularly limited.
Through the arrangement, when the operation platform is erected, a constructor can stand on the corresponding bearing plate 21 to implement construction operation, at this time, if the erection position of the operation platform is found to be far away from the installation position of the tower crane wall attaching piece, the bearing plate 21 of the platform single 201 can move along the vertical direction only by the constructor entering the passage inside the tower crane standard section 100 to operate the rotary handle 314 of the corresponding linear driving member 3 of the platform single 201, so that the purpose of adjusting the position of the bearing plate 21 in the vertical direction is achieved, the operation platform is not required to be disassembled and then is erected again, and in the process of moving the bearing plate 21 along the vertical direction, the traction rope 41 can be kept in a tensioning state all the time under the action of the tensioning mechanism to pull the bearing member 2, so that reliable safety guarantee is provided for the constructor to implement construction operation on the bearing plate 21.
Therefore, it can be seen that the operation platform provided in this embodiment is improved through the structure of the platform monomer 201, in the practical application process, the position of the bearing plate 21 on the vertical direction for bearing constructors and corresponding tool parts can be adjusted as required, so that even if deviation occurs in the erecting position of the operation platform in the earlier stage, the operation platform is not required to be erected again after being disassembled, meanwhile, the position of the bearing plate 21 on the vertical direction can be adjusted, the construction operation is more facilitated for constructors, for example, the installation of parts with wall parts at different height positions of the tower crane, and the practicability of the operation platform is greatly improved.
In addition, the straight line driving member 3 with a purely mechanical structure is adopted to drive the bearing plate 21 to reciprocate along the vertical direction, and other power devices (such as a cylinder, a hydraulic cylinder and the like) are not needed to be arranged, so that compared with the conventional mode of directly driving the bearing plate 21 to reciprocate along the vertical direction by using the straight line driving device such as the cylinder, the hydraulic cylinder and the like, the straight line driving device has the advantages of simple structure and lower cost, and is beneficial to practical popularization and application.
It should be noted that, in the actual erection process of the operation platform provided in this embodiment, each platform monomer 201 should be assembled on the ground first, then the tower crane is utilized to directly hoist and mount the platform monomer 201 to the corresponding position, at this time, the constructor only needs to install the support member 1 of each platform monomer 201 and the standard tower crane section 100 and install the traction unit 4 of each platform monomer 201 at high altitude, thereby simplifying the erection process of the operation platform as much as possible, reducing the risk of constructors when erecting the operation platform at high altitude for a long time, and guaranteeing the personal safety of constructors.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
