Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to an operating platform for disassembling and assembling wall-attached parts of a tower crane. Background Art

[0002] A tower crane, also known as a tower crane, is a commonly used material handling equipment in the construction field. Its height gradually increases with the continuous increase in the height of the building. When the tower crane is raised to a certain height, in order to ensure the safety and stability of the tower crane, a tower crane wall attachment is usually installed between the tower crane and the building. At the same time, the corresponding tower crane wall attachment also needs to be removed during the later dismantling of the tower crane.

[0003] In the prior art, when disassembling and assembling the tower crane wall attachment, it is often necessary to set up a corresponding operating platform at the tower crane standard section corresponding to the tower crane, so that the construction personnel can stand on the operating platform to carry out the disassembly and assembly of the tower crane wall attachment. However, the conventional operating platform is usually constructed with steel pipe fasteners, and its position is relatively fixed after the operation platform is erected. Usually, the installation position of the tower crane wall attachment is located above the operating platform. Therefore, once the position of the operating platform erected in the early stage deviates (for example, the operating platform is far away from the installation position of the tower crane wall attachment), the construction personnel cannot successfully complete the disassembly and assembly of the tower crane wall attachment, and they can only dismantle the operating platform and then re-erect the operating platform at a suitable position. The whole process will consume more manpower and material resources, and seriously affect the overall construction progress of the project. Summary of the invention

DETAILED DESCRIPTION

[0038] This embodiment provides an operating platform for disassembling and assembling tower crane wall parts, which is used to provide a platform for construction workers to move freely when disassembling and assembling tower crane wall parts. Figure 1 and Figure 2The operating platform includes a tower crane standard section 100 and a platform body 200. The platform body 200 includes a plurality of independently arranged platform monomers 201, and the plurality of platform monomers 201 are sequentially arranged on the outside of the tower crane standard section 100 along the circumference of the tower crane standard section 100. The tower crane standard section 100 is surrounded in the middle by the plurality of platform monomers 201, so that the construction personnel can move freely around the tower crane standard section 100. It can be understood that the platform monomers 201 of this embodiment are arranged in four, and the tower crane standard section 100 is a rectangular structure. At this time, the tower crane standard section 100 includes at least four vertically arranged columns 101, and the four platform monomers 201 are sequentially arranged on the outside of the four columns 101. As a preferred solution, each platform monomer 201 is slidably sleeved on the column 101 to connect each platform monomer 201 with the column 101 as a whole, and the platform monomer 201 can also move up and down relative to the column 101.

[0039] Considering that the existing operating platform is relatively fixed once it is erected, the position of the operating platform is difficult to adjust, and there are certain limitations in use. To this end, this embodiment improves the structure of the platform unit 201 so that the position of the platform unit in the vertical direction can be adjusted as needed to improve the practicality of the operating platform. Figure 1 and Figure 3 The platform unit 201 includes a supporting member 1, a bearing member 2, a linear driving member 3 and a traction unit 4.

[0040] In this embodiment, the support member 1 is horizontally arranged and connected to the tower crane standard section 100. At this time, the support member 1 serves as the bottom support structure of the platform unit 201 to provide reliable support from the bottom. Figure 2 and Figure 3 The supporting structure 1 includes a supporting plate 11 and a reinforcing column 12. The inner side of the supporting plate 11 is connected to the standard section 100 of the tower crane. The reinforcing column 12 is obliquely arranged below the supporting plate 11. The higher side of the reinforcing column 12 is connected to the bottom of the supporting plate 11, and the lower side of the reinforcing column 12 is connected to the standard section 100 of the tower crane. At this time, the supporting structure composed of the supporting plate 11 and the reinforcing column 12 can provide reliable support from the bottom.

[0041] It should be noted that in this embodiment, the number of the reinforcing columns 12 of each supporting member 1 is set to two, and the two reinforcing columns 12 are sequentially arranged on both sides of the supporting plate 11 along the length direction of the supporting plate 11. Figure 2As shown, the structural strength of the support member 1 is further improved, and the stability of the support plate 11 is improved. Of course, in the specific implementation, the number and position of the reinforcing columns 12 can also be set as needed, and no special limitation is made here; at the same time, the connection method between the above-mentioned support plate 11 and the tower crane standard section 100 and the connection method between the reinforcing column 12 and the tower crane standard section 100 can both be welded or detachably connected. In order to facilitate the subsequent disassembly of the operating platform, in this embodiment, the connection method between the support plate 11 and the tower crane standard section 100 and the connection method between the reinforcing column 12 and the tower crane standard section 100 both adopt a detachable connection method.

[0042] In this embodiment, the bearing member 2 is disposed above the supporting member 1 and is parallel to the supporting member 1. At this time, the bearing member 2 serves as a bearing component of the platform unit 201 to carry related construction personnel and tool parts so that the construction personnel can move freely to carry out construction work. Figure 3 The load-bearing member 2 includes a load-bearing plate 21 and a guardrail 22, wherein the load-bearing plate 21 is arranged in parallel with the supporting member 1, specifically, the load-bearing plate 21 is arranged in parallel with the supporting plate 11, and the guardrail 22 is arranged at the top outer edge of the load-bearing plate 21 to provide reliable protection from the outside through the guardrail 22. It can be understood that in order to facilitate the construction personnel to climb from the passage inside the tower crane standard section 100 to the load-bearing plate 21, at this time, the load-bearing plate 21 is close to the outer edge of one side of the tower crane standard section 100 without a guardrail 22, thereby relying on the tower crane standard section 100 itself as a protective structure.

[0043] Meanwhile, continue to refer to Figure 3 , a corresponding anti-slip strip 211 can be set on the top surface of the bearing plate 21 to improve the anti-slip performance of the bearing plate 21 and prevent the construction workers from slipping when standing on the bearing plate 21 and moving freely. In addition, the bearing plate 21 can adopt a mesh plate with a mesh structure to reduce the weight of the bearing plate 21 as much as possible, which is conducive to 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 monomer 201 can also be slidably set on the column 101 to connect the bearing plate 21 of each platform monomer 201 with the column 101 as a whole, and the bearing plate 21 can also slide up and down relative to the column 101 to further improve the stability of the bearing plate 21.

[0044] In this embodiment, the linear driving member 3 is arranged at the top of the supporting member 1, and the output end of the linear driving member 3 is connected to the bottom of the load-bearing member 2. Specifically, the output end of the linear driving member 3 is connected to the bottom of the load-bearing plate 21, and the connection position between the two is located at the center of gravity of the load-bearing plate 21, so that the load-bearing plate 21 of the load-bearing member 2 can be driven to reciprocate in the vertical direction by the linear driving member 3, thereby realizing the adjustment of the position of the load-bearing plate 21 in the vertical direction within a certain height range, so as to facilitate the construction personnel to smoothly implement related construction operations.

[0045] For details, please refer to Figure 4 The linear driving component 3 includes a driving component 31 and two lifting units 32. The two lifting units 32 are arranged in sequence along the width direction of the supporting plate 11 of the supporting component 1, so as to drive the supporting plate 21 to move in the vertical direction through the two lifting units 32, thereby improving the stability of the supporting plate 21 during the movement.

[0046] Among them, continue to refer to Figure 4 The lifting unit 32 includes a fixed cylinder 321, a first bevel gear 322 and a lifting screw rod 323. The fixed cylinder 321 is vertically arranged on the supporting member 1. In this embodiment, the fixed cylinder 321 is vertically arranged on the top of the supporting plate 11, and the first bevel gear 322 is freely rotatably arranged horizontally on the top of the fixed cylinder 321. The top end of the lifting screw rod 323 is connected to the bottom of the supporting plate 21 of the supporting member 2, and the bottom end of the lifting screw rod 323 vertically passes through the first bevel gear 322 downward and extends to the inside of the fixed cylinder 321. The lifting screw rod 323 is slidably matched with the fixed cylinder 321, the first bevel gear 322 and the lifting screw rod 323 are coaxially arranged, and the first bevel gear 322 and the lifting screw rod 323 are threadedly connected. It can be understood that the sliding cooperation between the lifting screw rod 323 and the fixed cylinder 321 is specifically that a slider (not shown in the figure) is provided inside the fixed cylinder 321 for sliding movement, and the end of the lifting screw rod 323 away from the supporting plate 21 passes through the first bevel gear 322 and extends into the fixed cylinder 321 and is connected to the slider. At this time, a threaded hole is opened in the middle of the first bevel gear 322 to facilitate the threaded connection between the lifting screw rod 323 and the first bevel gear 322.

[0047] The driving component 31 is used to drive the first bevel gears 322 of the two lifting units 32 to rotate simultaneously. When the first bevel gears 322 of the two lifting units 32 rotate, based on the principle of threaded transmission, the circular motion of the first bevel gears 322 in the horizontal direction will be converted into the linear motion of the lifting screw 323 in the vertical direction, and then the lifting screws 323 of the two lifting units 32 push the supporting plate 21 to drive the supporting plate 21 to move in the vertical direction.

[0048] Specifically, in order to realize that one driving component 31 drives the first bevel gears 322 of the two lifting units 32 to rotate at the same time, continue to refer to Figure 4The driving component 31 of this embodiment includes a connecting plate 311, a bearing seat 312, a driving shaft 313, a rotating handle 314, and a second bevel gear 315 corresponding to the first bevel gear 322, that is, one first bevel gear 322 corresponds to one second bevel gear 315. At this time, the fixing cylinders 321 of the two lifting units 32 are connected through a horizontally arranged connecting plate 311, the bearing seat 312 is arranged on the top of the connecting plate 311, the driving shaft 313 is arranged horizontally along the width direction of the supporting plate 11 of the supporting member 1, the driving shaft 313 is freely rotatably arranged on the connecting plate 311 through the bearing seat 312, the rotating handle 314 is arranged at one end of the driving shaft 313 facing the tower crane standard section 100, the second bevel gear 315 is sleeved on the outer wall of the driving shaft 313 and rotates coaxially with the driving shaft 313, and the second bevel gear 315 is meshed with the first bevel gear 322.

[0049] With such arrangement, when the rotating handle 314 is rotated, the rotating handle 314 drives the driving shaft 313 to rotate, so as to drive the two second bevel gears 315 to rotate through the driving shaft 313. At this time, the two second bevel gears 315 respectively drive the first bevel gears 322 of the two lifting units 32 to rotate, so that the lifting screws 323 of the two lifting units 32 can move in the vertical direction, so as to drive the bearing plate 21 to move in the vertical direction through the lifting screws 323. At the same time, by arranging the rotating handle 314 at one end of the driving shaft 313 facing the tower crane standard section 100, when it is necessary to adjust the position of the bearing plate 21 in the vertical direction, the construction personnel only need to stand in the channel inside the tower crane standard section 100 to operate the rotating handle 314, which is simple and convenient to operate and can effectively ensure the personal safety of the construction personnel.

[0050] In addition, continue to refer to Figure 4 In this embodiment, each lifting unit 32 also includes two guide members 324, and the two guide members 324 are respectively arranged on 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 member 324 is a retractable structure, and the fixed end of the guide member 324 is connected to the top of the support plate 11 of the support member 1, and the retractable end of the guide member 324 is connected to the bottom of the support plate 21 of the support member 2. The guide members 324 of the two lifting units 32 support the support plate 21 from all sides of the bottom of the support plate 21, and guide and constrain the movement of the support plate 21 in the vertical direction, so as to improve the stability of the support plate 21 during the reciprocating motion in the vertical direction.

[0051] For details, please refer to Figure 5The guide member 324 includes a fixed column 3241, a telescopic column 3242 and a buffer spring 3243. The fixed column 3241 is fixedly arranged on the support plate 11 of the support member 1. The telescopic column 3242 is slidably arranged inside the fixed column 3241. The buffer spring 3243 is arranged inside the fixed column 3241. One end of the buffer spring 3243 is connected to the bottom end of the telescopic column 3242, and the other end of the buffer spring 3243 is connected to the fixed column 3241. The top end of the telescopic column 3242 is connected to the bearing plate 21 of the bearing member 2. When the lifting screw 323 drives the bearing plate 21 to reciprocate in the vertical direction, the telescopic column 3242 can slide freely inside the fixed column 3241, so that the guide member 324 plays a good guiding role. At the same time, the additional buffer spring 3243 can play a certain buffering role, so as to further improve the stability of the bearing plate 21 when it reciprocates in the vertical direction.

[0052] In this embodiment, the traction unit 4 is used to reduce the risk of the load-bearing plate 21 falling during actual use, so as to further improve the reliability of each platform unit 201. Figure 1 The traction unit 4 includes a traction rope 41 and a tensioning mechanism. One end of the traction rope 41 is connected to the outer edge of the load-bearing member 2. Specifically, the traction rope 41 is connected to the top of the guardrail 22 arranged at the top outer edge of the load-bearing plate 21, so as to avoid the traction rope 41 from interfering with the free movement of construction workers on the load-bearing plate 21 as much as possible. At this time, the other end of the traction rope 41 is connected to the tensioning mechanism, which is used to keep the traction rope 41 in a tensioned state when the load-bearing plate 21 of the load-bearing member 2 reciprocates in the vertical direction, so as to reliably pull the load-bearing member 2 through the traction rope 41 that is always in a tensioned state.

[0053] For details, please refer to Figure 1 and Figure 6 The tensioning mechanism includes a fixed pulley 42, a winch drum 43, a rotating shaft 44, a gear 45 and a rack 46. The fixed pulley 42 is fixedly arranged on the tower crane standard section 100, and the fixed pulley 42 is located above the bearing member 2. The rotating shaft 44 can be freely rotatably arranged on the tower crane standard section 100, and the rotating shaft 44 is located below the fixed pulley 42. For example, the rotating shaft 44 of this embodiment can be freely rotatably arranged on the side of the column 101 of the tower crane standard section 100, and the axis of the rotating shaft 44 is parallel to the length direction of the bearing plate 21, as shown in FIG. Figure 1 shown.

[0054] The winch drum 43 and the gear 45 are simultaneously sleeved on the outer wall of the shaft 44, and the winch drum 43 and the gear 45 rotate coaxially with the shaft 44, and the rack 46 is vertically arranged on the inner side of the bearing plate 21 of the bearing member 2, please refer to Figure 3The rack 46 in this embodiment is vertically arranged on one side of the bearing plate 21 close to the tower crane standard section 100, and the rack 46 is meshed with the gear 45. At this time, the end of the traction rope 41 away from the bearing member 2 passes around the fixed pulley 42 and then extends vertically downward and is connected to the winch drum 43.

[0055] In this configuration, assuming that the carrying plate 21 is at the lowest position in the initial state and the traction rope 41 is in a tensioned state, when the carrying plate 21 moves upward under the action of the linear drive member 3, the carrying plate 21 drives the rack 46 to move upward synchronously, and the rack 46 moving upward drives the gear 45 to rotate, and then drives the rotating shaft 44 to rotate through the gear 45. At this time, the rotating shaft 44 drives the winch drum 43 to rotate so that the traction rope 41 is continuously wound around the winch drum 43 to achieve winding, so that the traction rope 41 between the winch drum 43 and the guardrail 22 is It is always kept in a tensioned state to hold the load-bearing member 2 and reduce the risk of the load-bearing member 2 falling; on the contrary, when the load-bearing plate 21 moves downward under the drive of the linear drive member 3, the load-bearing plate 21 drives the rack 46 to move downward synchronously, and the rack 46 moving downward drives the gear 45 to rotate in the opposite direction. At this time, the rotating shaft 44 rotates in the opposite direction under the action of the gear 45, and then the reverse rotating rotating shaft 44 drives the winch drum 43 to rotate in the opposite direction to realize the line release, and also enables the traction rope 41 between the winch drum 43 and the guardrail 22 to always be in a tensioned state.

[0056] It can be seen that the present embodiment adds a traction unit 4 to each platform monomer 201, and sets a tensioning mechanism for retracting and releasing the traction rope 41 according to the movement of the load-bearing plate 21. The structural design is ingenious, and there is no need to add an additional driving device to ensure that the traction rope 41 is always in a tensioned state during the reciprocating movement of the load-bearing plate 21 in the vertical direction. The traction rope 41 in the tensioned state can be used to reliably pull the load-bearing component 2, thereby effectively improving the reliability of each platform monomer 201 during actual use, and providing reliable safety protection for construction personnel performing corresponding construction operations.

[0057] It should be noted that each platform unit 201 is provided with at least one traction unit 4. Preferably, in this embodiment, each platform unit 201 is provided with two traction units 4. The two traction units 4 are sequentially arranged on both 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, thereby further improving the reliability of the platform unit 201 when in use. At this time, the fixed pulley 42 and the rotating shaft 44 of the same traction unit 4 are arranged on the same side of the same column 101 of the tower crane standard section 100. Of course, in actual implementation, more traction units 4 can be arranged as needed, and the number and position of the traction units 4 are not particularly limited here.

[0058] Through the above-mentioned arrangement, when the operating platform is erected, the construction personnel can stand on the corresponding bearing plate 21 to carry out construction work. At this time, if it is found that the erection position of the operating platform is far away from the installation position of the tower crane wall attachment, the construction personnel only need to enter the channel inside the tower crane standard section 100 to operate the rotating handle 314 of the linear driving component 3 of the corresponding platform monomer 201 to make the bearing plate 21 of the platform monomer 201 move in the vertical direction, so as to achieve the purpose of adjusting the position of the bearing plate 21 in the vertical direction. There is no need to dismantle the operating platform and then re-erect it. In the process of the bearing plate 21 moving in the vertical direction, the traction rope 41 can always remain in a tensioned state under the action of the tensioning mechanism to pull the bearing component 2, thereby providing reliable safety protection for the construction personnel to carry out construction work on the bearing plate 21.

[0059] It can be seen that the operating platform provided in this embodiment improves the structure of the platform unit 201. In actual application, the position of the bearing plate 21 used to carry construction personnel and corresponding tool parts can be adjusted in the vertical direction as needed, so that even if the erection position of the operating platform in the early stage deviates, there is no need to dismantle the operating platform and then re-erect it. At the same time, since the position of the bearing plate 21 in the vertical direction can be adjusted, it is more conducive to the construction personnel to carry out the corresponding construction operations, such as installing parts of the tower crane wall attachments at different heights, which greatly improves the practicability of the operating platform.

[0060] In addition, by adopting a purely mechanical linear drive component 3 to drive the support plate 21 to reciprocate in the vertical direction, there is no need to configure other power devices (such as cylinders, hydraulic cylinders, etc.). Compared with the conventional use of linear drive devices such as cylinders and hydraulic cylinders to directly drive the support plate 21 to reciprocate in the vertical direction, the structure is simple and the cost is lower, which is conducive to practical promotion and application.

[0061] It should be noted that, during the actual erection process of the operating platform provided in this embodiment, each platform unit 201 should be assembled on the ground first, and then the platform unit 201 should be directly lifted to the corresponding position by a tower crane for installation. At this time, the construction personnel only need to install the supporting structure 1 and the tower crane standard section 100 of each platform unit 201 and the traction unit 4 of each platform unit 201 at high altitude, thereby simplifying the erection process of the operating platform as much as possible, reducing the risk of construction personnel erecting the operating platform at high altitude for a long time, and ensuring the personal safety of construction personnel.

[0062] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
