Description

Technical Field

[0001] This application relates to the field of temporary walkways, and in particular to a retractable walkway connecting climbing formwork and tower cranes. Background Art

[0002] In many high-rise building construction projects, tower cranes are almost essential large-scale construction facilities. In order for the tower crane operator to enter the operating room at the top of the tower crane more quickly, as Figure 1 shown, label 1 is a high-rise building, label 11 is climbing formwork, and label 12 is a tower crane. Usually, during the construction of high-rise building projects, climbing formwork facilities attached to the outside of the building are adopted. The operator walks through the climbing formwork facilities to the tower crane steel frame close to the building, climbs up along the stairs inside the tower crane steel frame, and finally enters the operating room.

[0003] However, there is often a certain distance between the tall tower crane and the climbing formwork facilities under construction. Personnel cannot directly walk from the edge of the climbing formwork facilities to the inside of the tower crane steel frame. Therefore, a temporary connecting walkway needs to be built. If only a steel plate or thick wooden board used in the traditional connection method is placed as the walkway, it is obviously not safe; if a relatively complex corridor facility is first built indoors and then transported to the gap above between the tower crane and the building, the walkway needs to be moved before and after each tower crane climb, which is rather inconvenient, and the safety and convenience of the construction personnel walking between the climbing formwork equipment and the tower crane equipment are insufficient. Summary of the Utility Model

[0004] In order to improve the safety and convenience of the construction personnel walking between the climbing formwork and the tower crane, this application provides a retractable walkway connecting the climbing formwork and the tower crane.

[0005] The retractable walkway connecting the climbing formwork and the tower crane provided by this application adopts the following technical solutions:

[0006] A retractable walkway connecting the climbing formwork and the tower crane includes a bearing member hinged to the climbing formwork. The bearing member is used for personnel to walk on. One end of the bearing member away from the climbing formwork is placed on the tower crane. Protective fences are symmetrically arranged on both sides of the bearing member, and the protective fences are connected to the bearing member.

[0007] By adopting the above technical solution, when construction workers need to walk between the climbing formwork and the tower crane, they unwind the load-bearing member, so that the end of the load-bearing member away from the climbing formwork rotates around the hinge end until the end of the load-bearing member away from the climbing formwork is placed on the tower crane, realizing the possibility for construction workers to walk between the climbing formwork and the tower crane. By setting up guardrails, the personal safety of construction workers during the passage is enhanced; by hinging the load-bearing member to the climbing formwork, the connection stability between the load-bearing member and the climbing formwork is improved. When the tower crane needs to climb as a whole, the load-bearing member is retracted before climbing, reducing the possibility that the presence of the load-bearing member hinders the climbing of the tower crane. After the tower crane finishes climbing, the load-bearing member is lowered again to allow personnel to pass. At the same time, by hinging the load-bearing member to the climbing formwork, when the tower crane climbs, it is not necessary to extend the load-bearing member towards the inside of the climbing formwork, reducing the possibility that the load-bearing member needs to straddle the climbing formwork pedal and that multiple workers need to spend a lot of effort to move the load-bearing member, thereby reducing the operation complexity. At the same time, it reduces the possibility that the load-bearing member slips and falls due to accidentally letting go during the movement, resulting in casualties, and thus improves the safety and convenience of construction workers walking between the climbing formwork and the tower crane.

[0008] Optionally, a lifting ring is connected to the load-bearing member, a lifting rope is connected to the lifting ring, and the end of the lifting rope away from the load-bearing member is connected to the climbing formwork.

[0009] By adopting the above technical solution, the lifting rope further supports the load-bearing member, enhancing the structural safety of the load-bearing member and providing safety for construction workers to walk between the climbing formwork and the tower crane.

[0010] Optionally, the climbing formwork is equipped with a winding and unwinding mechanism for winding or unwinding the lifting rope.

[0011] By adopting the above technical solution, when the winding and unwinding mechanism is set up to pull the lifting rope to wind or unwind the load-bearing member, the winding and unwinding of the lifting rope is controlled by the winding and unwinding mechanism, improving the convenience of winding and unwinding the lifting rope, reducing the possibility of personnel falling caused by manually pulling the lifting rope, and improving the safety of winding and unwinding the load-bearing member.

[0012] Optionally, the winding and unwinding mechanism includes a fixed pulley assembly and a winding and unwinding assembly. The fixed pulley assembly is assembled with the climbing formwork, the winding and unwinding assembly is assembled with the climbing formwork, the fixed pulley assembly is located at the top of the winding and unwinding assembly, the end of the lifting rope away from the lifting ring is placed on the fixed pulley assembly and is connected to the winding and unwinding assembly, and the winding and unwinding assembly is used for winding or unwinding the lifting rope.

[0013] By adopting the above technical solution, when it is necessary to unwind the lifting rope, the winding and unwinding assembly is started, and the lifting rope is unwound under the action of the winding and unwinding assembly. The lifting rope is placed on the fixed pulley assembly. Compared with directly pulling the lifting rope, the fixed pulley assembly can reduce friction and reduce the possibility that the lifting rope breaks due to direct pulling by the winding and unwinding assembly, threatening personal safety, and improving construction safety.

[0014] Optionally, a plurality of punching holes are formed in the top wall of the carrier.

[0015] By adopting the above technical solution, punching holes are formed in the carrier to replace the steel plates or thick wooden boards used in the traditional connection method, improving the use safety of the carrier. At the same time, the weight of the carrier is reduced, facilitating the process of retracting and extending the carrier, thereby improving the convenience of use of the carrier.

[0016] Optionally, an extension section is connected to one end of the carrier away from the climbing formwork, and the extension section is used to provide a connection point for extending the carrier.

[0017] By adopting the above technical solution, when the distance between the climbing formwork and the tower crane is far, the carrier needs to be extended so that the carrier can be erected on the tower crane, improving the safety of personnel walking on the carrier. The extension section provides a connection point for extending the carrier, improving the connection stability between the carrier and the extension structure.

[0018] Optionally, the carrier is composed of a walkway and a bottom frame. The walkway is used for people to walk, the bottom frame frames the walkway, and the inner wall of the bottom frame is connected to the outer wall of the walkway.

[0019] By adopting the above technical solution, the bottom frame provides a frame support for the setting of the walkway, enhancing the structural safety of the walkway.

[0020] Optionally, the guardrail includes a frame member, vertical bars, a first cross bar, and a second cross bar. The frame member is connected to the carrier, the vertical bars are connected to the inner wall of the frame member, one end of the first cross bar is connected to the vertical bars, the other end of the first cross bar away from the vertical bars is connected to the frame member, one end of the second cross bar is connected to the vertical bars, and the other end of the second cross bar away from the vertical bars is connected to the frame member.

[0021] By adopting the above technical solution, the connection between the frame member, the vertical bars, and the cross bars provides safety protection for personnel walking. The connection structure is simple, the structure is simple, which is convenient for erection, and at the same time, the weight of the overall structure is reduced, facilitating the retraction and extension of the guardrail and improving the convenience.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. When construction workers need to move between the climbing formwork and the tower crane, the load-bearing member is unreeled, so that the end of the load-bearing member away from the climbing formwork rotates around the hinge end until the end of the load-bearing member away from the climbing formwork is placed on the tower crane, realizing the possibility for construction workers to move between the climbing formwork and the tower crane. The safety guarantee of construction workers during the passage is enhanced by setting up a guardrail; by hinging the load-bearing member to the climbing formwork, the connection stability between the load-bearing member and the climbing formwork is improved. When the tower crane needs to climb as a whole, the load-bearing member is retracted before climbing, reducing the possibility that the existence of the load-bearing member hinders the climbing of the tower crane. After the tower crane finishes climbing, the load-bearing member is lowered again to allow personnel to pass. At the same time, by hinging the load-bearing member to the climbing formwork, when the tower crane climbs, it is not necessary to extend the load-bearing member towards the inside of the climbing formwork, reducing the possibility that the load-bearing member needs to straddle the climbing formwork pedal and multiple workers need to spend a lot of effort to move the load-bearing member, thereby reducing the operation complexity. At the same time, it reduces the possibility that the load-bearing member slips and falls as a whole due to accidentally letting go during the movement, resulting in casualties, thereby improving the safety and convenience of construction workers moving between the climbing formwork and the tower crane;

[0025] 3. Punch holes are made in the load-bearing member to replace the steel plates or thick wooden boards used in the traditional connection method, improving the use safety of the load-bearing member. At the same time, the weight of the load-bearing member is reduced, bringing convenience to the winding and unwinding process of the load-bearing member, thereby improving the use convenience of the load-bearing member.

[0033] The following further elaborates on this application Figures 1-5 in conjunction with the appended drawings.

[0034] An embodiment of this application discloses a retractable walkway for connecting a climbing formwork and a tower crane.

[0035] Referring to Figure 2 and Figure 3 , a retractable walkway 22 for connecting a climbing formwork and a tower crane includes a bearing member 2. The bearing member 2 is used for personnel to walk on. One side of the bearing member 2 is fixedly connected with an L-shaped hinge 21. The end of the L-shaped hinge 21 away from the bearing member 2 is fixedly connected with the climbing formwork. The bearing member 2 is hinged to the climbing formwork through the L-shaped hinge 21, improving the stability of the connection structure of the bearing member 2. The end of the bearing member 2 away from the climbing formwork is placed on the tower crane. The climbing formwork and the tower crane are located in the length direction of the bearing member 2. Guardrails 3 are symmetrically arranged on both sides in the length direction of the bearing member 2. The bottom wall of the guardrail 3 is fixedly connected with the top wall of the bearing member 2.

[0036] When construction workers need to walk between the climbing formwork and the tower crane, the construction workers hold the guardrail 3 by hand and move the bearing member 2, so that the end of the bearing member 2 away from the climbing formwork rotates around the hinge axis of the hinge until the end of the bearing member 2 away from the climbing formwork is placed on the tower crane, forming a walking passage between the climbing formwork and the tower crane. The construction workers walk between the two symmetrically arranged guardrails 3. The guardrail 3 enhances the personal safety guarantee during the passage of the construction workers. At the same time, the bearing member 2 is hinged to the climbing formwork, improving the connection stability between the bearing member 2 and the climbing formwork. When the tower crane needs to climb as a whole, the bearing member 2 is retracted before climbing, reducing the possibility that the presence of the bearing member 2 hinders the climbing of the tower crane. After the tower crane finishes climbing, the bearing member 2 is lowered again to allow personnel to pass, improving the safety and convenience of the construction workers walking between the climbing formwork and the tower crane.

[0037] Referring to Figure 2 and Figure 4, the carrier 2 is composed of a walkway 22 and a bottom frame 23. The walkway 22 is used for people to walk. The bottom frame 23 is in the shape of a rectangular frame with a hollow middle. The bottom frame 23 frames the walkway 22, and the inner wall of the bottom frame 23 is fixedly connected to the outer wall of the walkway 22. The climbing formwork and the tower crane are located in the length direction of the walkway 22. The length direction of the bottom frame 23 is consistent with the length direction of the walkway 22. One end of the bottom frame 23 is fixedly connected to an L-shaped hinge 21. The guardrail 3 is fixedly connected to the top wall of the bottom frame 23. The bottom frame 23 provides a frame support for the setting of the walkway 22, enhancing the structural safety of the walkway 22.

[0038] To reduce the weight of the walkway 22, facilitate the retraction and extension process of the walkway 22, and improve the convenience of use of the walkway 22, a plurality of punching holes are opened through the top wall of the walkway 22. In this embodiment, the walkway 22 is made of punched plate.

[0039] Refer to Figure 4 and Figure 5 , on both sides of the bottom frame 23 in the length direction, lifting rings 4 are symmetrically and fixedly connected. The lifting rings 4 are located at one end of the bottom frame 23 away from the climbing formwork. The lifting rings 4 are fixedly connected to lifting ropes 41. One end of the lifting rope 41 away from the bottom frame 23 is connected to the climbing formwork. A triangular structure is formed among the lifting rope 41, the bottom frame 23 and the climbing formwork.

[0040] When the bottom frame 23 is erected on the tower crane, the lifting rope 41 pulls the bottom frame 23. The bottom frame 23 is connected to the walkway 22, thereby further supporting the bottom frame 23, and further enhancing the structural safety of the walkway 22, providing safety for construction workers to walk between the climbing formwork and the tower crane.

[0041] To facilitate the retraction and extension operation of the walkway 22 by pulling the lifting rope 41, the climbing formwork is equipped with a retraction and extension mechanism. The retraction and extension mechanism is used to wind or unwind the lifting rope 41. By pulling the lifting rope 41 through the retraction and extension mechanism, the walkway 22 is retracted and extended, improving the convenience of retracting and extending the lifting rope 41, reducing the possibility of personnel falling caused by manually pulling the lifting rope 41 by personnel, and improving the safety of retracting and extending the walkway 22.

[0042] The retraction and extension mechanism includes a fixed pulley assembly 5 and a retraction and extension assembly 51. The fixed pulley assembly 5 is assembled with the climbing formwork. One end of the lifting rope 41 away from the lifting ring 4 is connected to the retraction and extension assembly 51 through being arranged on the fixed pulley assembly 5. The retraction and extension assembly 51 is used to wind or unwind the lifting rope 41. The retraction and extension assembly 51 is fixedly connected to the climbing formwork. One end of the lifting rope 41 away from the lifting ring 4 is fixedly connected to the climbing formwork through the retraction and extension assembly 51. The fixed pulley assembly 5 is located at the top of the retraction and extension assembly 51. In this embodiment, the fixed pulley assembly 5 uses a fixed pulley, and the retraction and extension assembly 51 uses a winch or a handwheel to realize the unwinding or winding operation of the lifting rope 41. The winch or the handwheel is assembled on the lifting rope 41 through the fixed pulley, which is prior art and will not be elaborated here.

[0043] When the sling 41 is unwound, the winding and unwinding assembly 51 is started. Under the action of the winding and unwinding assembly 51, the sling 41 is unwound. The sling 41 pulls the bottom frame 23 to move, thereby driving the walkway 22 to be wound and unwound, so that the walkway 22 is far from or erected on the tower crane through the bottom frame 23. The sling 41 is erected on the fixed pulley assembly 5. Compared with directly pulling the sling 41, the fixed pulley assembly 5 can reduce friction and reduce the possibility that the sling 41 breaks due to the direct pulling of the winding and unwinding assembly 51, threatening personal safety, and improve construction safety.

[0044] In actual construction, the distance between the climbing formwork and the tower crane varies depending on the construction site. When the distance between the climbing formwork and the tower crane is far and the walkway 22 cannot be erected on the tower crane, in order to improve the applicability of the walkway 22 and the safety of construction workers during construction, an extension section 6 is fixedly connected to the end of the bottom frame 23 far from the climbing formwork. The extension section 6 is used to provide a connection point for lengthening the walkway 22. When the length of the walkway 22 is insufficient, another frame body with a walkway 22 is connected to the extension section 6 to lengthen the overall walkway 22. The bottom frames 23 are firmly connected by clamps. The number of sling rings 4 is multiple and distributed along the length direction of the bottom frame 23. To improve the stability of the sling 41 pulling the bottom frame 23, when the walkway 22 is lengthened, the sling 41 is connected to the sling ring 4 close to rather than erected on the tower crane.

[0045] The guardrail 3 includes a frame member 31, vertical rods 32, first crossbars 33 and second crossbars 34. The frame member 31 is in a U shape with an open bottom. The bottom wall of the frame member 31 is fixedly connected to the top wall of the bottom frame 23. The vertical rods 32 are arranged vertically, and the top walls of the vertical rods 32 are fixedly connected to the inner top wall of the frame member 31. The length direction of the first crossbars 33 is perpendicular to the length direction of the vertical rods 32. The number of the first crossbars 33 is multiple, and the number of the second crossbars 34 is multiple. Both the first crossbars 33 and the second crossbars 34 are distributed along the length direction of the vertical rods 32. One second crossbar 34 is arranged in the length direction of each first crossbar 33, and the length direction of the second crossbar 34 is consistent with the length direction of the first crossbar 33. In this embodiment, the number of the first crossbars 33 is two, and the number of the second crossbars 34 is two. One end of the first crossbar 33 is connected to the vertical rod 32, and the other end of the first crossbar 33 far from the vertical rod 32 is connected to the inner side wall of the frame member 31. One end of the second crossbar 34 is connected to the vertical rod 32 on the side far from the first crossbar 33, and the other end of the second crossbar 34 far from the vertical rod 32 is connected to the inner side wall of the frame member 31.

[0046] The connection between the frame member 31, the vertical rods 32 and the crossbars provides safety protection for personnel walking. The connection structure is simple and convenient to build. At the same time, it reduces the weight of the overall structure, facilitates the winding and unwinding of the guardrail 3, and improves convenience.

[0047] The implementation principle of a retractable walkway 22 connecting a climbing formwork and a tower crane in an embodiment of the present application is as follows: When construction workers need to move between the climbing formwork and the tower crane, the retracting and deploying assembly 51 is activated. The retracting and deploying assembly 51 pays out the suspension rope 41. The suspension rope 41 pulls the end of the frame away from the climbing formwork to rotate around the hinge as the rotation axis until the end of the frame away from the climbing formwork is placed on the tower crane, so that the walkway 22 spans between the climbing formwork and the tower crane to form a walking passage. Construction workers move between the two symmetrically arranged guardrails 3. The guardrails 3 enhance the personal safety guarantee of construction workers during the passage. At the same time, the bottom frame 23 is hinged to the climbing formwork, improving the connection stability between the bottom frame 23 and the climbing formwork, and improving the stability and safety of construction workers walking on the walkway. When the tower crane needs to be lifted as a whole, the walkway 22 is retracted before lifting, reducing the possibility that the presence of the walkway 22 hinders the lifting of the tower crane. After the tower crane finishes lifting, the walkway 22 is lowered again to allow personnel to pass, improving the safety and convenience of construction workers moving between the climbing formwork and the tower crane.

[0048] The above are all the preferred embodiments of the present application. This embodiment is only an explanation of the present application and does not limit the protection scope of the present application in sequence. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
