Description

Technical Field

[0001] This utility model relates to the field of hoistway operating frame technology, and in particular to an integral hoisting hoistway operating frame. Background Technology

[0002] Traditional elevator shaft operating scaffolds typically consist of steel pipe and coupler scaffolding or simple steel frames as the main structure, supplemented by wooden treads, safety nets, and other components. In elevator shaft construction scenarios, the operating scaffold needs to be assembled on-site according to the shaft dimensions and ascended layer by layer within the shaft to meet the operational needs of different floors.

[0003] However, traditional scaffolding, which is mainly constructed using steel pipe coupler scaffolding or simple steel frames, supplemented by wooden planks, safety nets and other components, requires repeated disassembly and reinstallation of the scaffolding after each layer of construction is completed. The disassembly and reinstallation of the scaffolding is mainly done manually, which limits the efficiency of repeated disassembly and reinstallation, resulting in low overall construction efficiency. Utility Model Content

[0004] To address the shortcomings in the aforementioned background technology, this utility model proposes an integrated lifting shaft operating frame, which solves the technical problem that existing shaft operating frames require repeated disassembly and assembly, resulting in low overall construction efficiency.

[0005] The technical solution of this utility model is implemented as follows: an integral lifting shaft operating frame includes a bottom support structure that abuts against the shaft. The top of the bottom support structure is provided with a support frame detachably connected to the inner wall of the shaft. A construction platform is provided on the support frame, and lifting lugs for hoisting are also provided on the support frame. This application utilizes a shaft operating frame composed of a bottom support structure, a support frame, and a construction platform. The support frame is detachably connected to the inner wall of the shaft. By disassembling the support frame from the inner wall, the lifting lugs can be connected by a crane, allowing the shaft operating frame to be hoisted as a whole to the required construction position. This avoids the need for repeated disassembly and adjustment of the shaft operating frame during construction, saving time and significantly improving overall construction efficiency. It solves the technical problem of low overall construction efficiency in existing shaft operating frames that require repeated disassembly and assembly.

[0006] Several of the lifting lugs are symmetrically arranged on the support frame. This arrangement is to ensure the stability of the crane's lifting operation and reduce the possibility of the hoistway operating frame tipping over during the lifting process.

[0007] Preferably, the construction platform includes several construction units, which are arranged vertically along the height of the shaft. The upper and lower construction units are fixedly connected, and a ladder connects the upper and lower construction units. The arrangement of several construction units allows construction personnel to ascend to higher positions along the shaft operating frame, facilitating the adjustment of positions within the shaft for construction work.

[0008] Preferably, the construction unit includes a support plate, which is quadrilateral in shape. Protective frames are welded around the four sides of the support plate. The support plate, located at the bottom of the construction platform, is laid on top of the support frames. The support plate is designed to support construction personnel, and the protective frames are designed to enhance the protection of construction personnel and ensure their safety. Specifically, the fixed connection between the upper and lower construction units refers to the fixed connection between the support plate of the upper construction unit and the protective frame of the lower construction unit, for example, by welding them together.

[0009] The support plate is made of corrugated steel plate because corrugated steel plate has excellent load-bearing capacity and the corrugated design gives the steel plate strong bending resistance and pressure distribution characteristics, so corrugated steel plate is selected for the support plate.

[0010] Preferably, a crossbar connects the two opposing protective frames. The crossbar is provided to securely connect the two opposing protective frames and ensure the strength of the protective frame arrangement.

[0011] Preferably, the opposite sides of the support frame are detachably connected to the inner wall of the shaft. This detachable connection significantly improves the connection strength between the support frame and the inner wall of the shaft, thereby helping to ensure the stability of the entire shaft operating frame.

[0012] Preferably, the support frame is a square bracket, with one side of the support frame connected to the inner wall of the shaft by bolts, and the other sides connected to the inner wall of the shaft by steel wire ropes. That is, one side of the support frame is detachably connected to the inner wall of the shaft by bolts, and the other three sides are detachably connected to the inner wall of the shaft by steel wire ropes. When detachably connected to the inner wall of the shaft by bolts, the bolts provide rigid support for the support frame, ensuring the stability of the detachable connection, while the steel wire ropes provide flexible tension, ensuring the convenience of the detachable connection.

[0013] Preferably, the base support structure includes a top plate, side plates, and diagonal braces, which together form a triangular base support structure. The top plate is connected to the support frame, and the side plates are provided with fixing frames that abut against the shaft. The triangular base support structure formed by the top plate, side plates, and diagonal braces makes the base support structure of this application more stable and less prone to deformation. The top plate, side plates, and diagonal braces are sequentially welded together to form the triangular base support structure.

[0014] Preferably, a first support rod connects the top plate and the diagonal brace, and a second support rod connects the side plate and the diagonal brace. The first support rod helps to improve the connection strength between the top plate and the diagonal brace, and the second support rod helps to improve the connection strength between the side plate and the diagonal brace.

[0015] Preferably, the angle between the top plate and the side plate is greater than 90° and less than 120°. The angle between the top plate and the side plate is greater than 90° and less than 120° because when the angle is 90°, the vertical support force of the bottom support structure is entirely borne by the fixed frame. However, when the angle is greater than 90°, the vertical support force of the bottom support structure is partially borne by the fixed frame. Under the same support force, the fixed frame is less prone to deformation when the angle between the top plate and the side plate is greater than 90°. When the angle between the top plate and the side plate is 120° or greater, the vertical support force of the bottom support structure is only partially borne by the fixed frame, and the entire hoistway operating frame is prone to tilting away from the fixed frame, which is detrimental to the stability of the entire hoistway operating frame. Therefore, the angle between the top plate and the side plate is greater than 90° and less than 120°.

[0016] Preferably, the fixing frame includes a fixed rod and a diagonal rod, with one end of the fixed rod and the diagonal rod fixedly connected, and the other end of both the fixed rod and the diagonal rod connected to the side plate to form a triangular shape. The fixed rod is used to abut against the shaft, wherein during the abutment process, the fixed rod abuts against a horizontal surface of the shaft, and the side plate abuts against a vertical surface of the shaft to ensure the stability of the abutment. In addition, during the abutment process between the fixed rod and the horizontal surface of the shaft, the diagonal rod is used to further support the fixed rod to ensure the abutment strength of the fixed rod. The other end of both the fixed rod and the diagonal rod are connected to the side plate to form a triangular shape, which greatly reduces the possibility of deformation of the fixing frame.

The support frame is detachably connected to the inner wall of the shaft.

This avoids the need for repeated disassembly and adjustment of the shaft operating frame during construction, saving time and greatly improving the overall construction efficiency.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: An integral hoisting shaft operating frame, such as Figure 1As shown, the system includes a bottom support structure 1 that abuts against the shaft. The top of the bottom support structure 1 is provided with a support frame 2 that is detachably connected to the inner wall 18 of the shaft. A construction platform 3 is mounted on the support frame 2, and lifting lugs 17 are provided on the support frame 2 for hoisting. This application utilizes a shaft operating frame composed of the bottom support structure 1, the support frame 2, and the construction platform 3, with the support frame 2 detachably connected to the inner wall 18 of the shaft. By disassembling the connection between the support frame 2 and the inner wall 18, the lifting lugs 17 can be connected by a crane, allowing the shaft operating frame to be hoisted as a whole to the required construction position. This avoids the need for repeated disassembly and adjustment of the shaft operating frame during construction, saving time and significantly improving overall construction efficiency. It solves the technical problem of low overall construction efficiency in existing technologies where the shaft operating frame requires repeated disassembly and assembly.

[0025] Several of the lifting lugs 17 are symmetrically arranged on the support frame 2. This arrangement is to ensure the stability of the crane's lifting operation and reduce the possibility of the hoistway operating frame tipping over during the lifting process.

[0026] Example 2, based on Example 1, provides an integrated hoisting shaft operating frame, such as... Figure 1 and Figure 2 As shown, the construction platform 3 includes several construction units, which are arranged vertically along the height of the shaft. The upper and lower construction units are fixedly connected, and a ladder 6 is provided between them. The arrangement of several construction units allows construction personnel to rise to higher positions along the shaft operating frame, which is beneficial for them to adjust to a suitable position within the shaft for construction.

[0027] Example 3, based on Example 2, provides an integrated lifting shaft operating frame. Figure 1 and Figure 2 As shown, the construction unit includes a support plate 7, which is quadrilateral in shape. Protective frames 8 are welded around the four sides of the support plate 7. The support plate 7, located at the bottom of the construction platform 3, is laid on top of the support frame 2. The support plate 7 is designed to support construction personnel, and the protective frames 8 are designed to enhance the protection of construction personnel and ensure their safety. The fixed connection between the upper and lower construction units specifically refers to the fixed connection between the support plate 7 of the upper construction unit and the protective frame 8 of the lower construction unit, for example, by welding them together.

[0028] The support plate 7 is made of corrugated steel plate. Because corrugated steel plate has excellent load-bearing capacity and the corrugated design gives the steel plate strong bending resistance and pressure distribution characteristics, corrugated steel plate is selected for support plate 7.

[0029] Example 4, based on Example 3, provides an integrated lifting shaft operating frame. Figure 1 and Figure 2 As shown, a crossbar 9 connects the two opposing protective frames 8. The crossbar 9 is provided to fix the two opposing protective frames 8 together and ensure the strength of the protective frame arrangement.

[0030] Example 5, based on Example 4, provides an integrated lifting shaft operating frame. Figure 1 and Figure 2 As shown, the opposite sides of the support frame 2 are detachably connected to the inner wall 18 of the shaft. This detachable connection significantly improves the connection strength between the support frame 2 and the inner wall 18 of the shaft, thereby enhancing the stability of the entire shaft operating frame.

[0031] Example 6, based on Example 5, provides an integrated lifting shaft operating frame. Figure 1 and Figure 2 As shown, the support frame 2 is a square bracket. One side of the support frame 2 is connected to the inner wall 18 of the shaft via bolts 4, and the other three sides are connected to the inner wall 18 of the shaft via steel wire ropes 5. That is, one side of the support frame 2 is detachably connected to the inner wall 18 of the shaft via bolts 4, and the other three sides are detachably connected to the inner wall 18 of the shaft via steel wire ropes 5. When detachably connected to the inner wall 18 of the shaft via bolts 4, the bolts 4 provide a rigid support for the support frame 2, ensuring the stability of the detachable connection, while the steel wire ropes 5 provide a flexible tension force for the support frame 2, ensuring the convenience of the detachable connection.

[0032] Example 7: Based on any one of Examples 1 to 6, an integral lifting shaft operating frame, Figure 1 and Figure 2 As shown, the base support structure 1 includes a top plate 10, side plates 11, and diagonal braces 12. The top plate 10, side plates 11, and diagonal braces 12 form a triangular base support structure 1. The top plate 10 is connected to the support frame 2, and the side plates 11 are provided with fixing frames that abut against the shaft. The triangular base support structure 1 formed by the top plate 10, side plates 11, and diagonal braces 12 makes the base support structure 1 of this application more stable and less prone to deformation. The top plate 10, side plates 11, and diagonal braces 12 are sequentially welded together to form the triangular base support structure 1.

[0033] Example 8, based on Example 7, provides an integrated hoisting shaft operating frame, such as... Figure 1As shown, a first support rod 15 connects the top plate 10 and the diagonal brace 12, and a second support rod 16 connects the side plate 11 and the diagonal brace 12. The first support rod 15 helps to improve the connection strength between the top plate 10 and the diagonal brace 12, and the second support rod 16 helps to improve the connection strength between the side plate 11 and the diagonal brace 12.

[0034] Example 9, based on Example 8, provides an integrated hoisting shaft operating frame, such as... Figure 1 As shown, the angle between the top plate 10 and the side plate 11 is greater than 90° and less than 120°. The angle between the top plate 10 and the side plate 11 is greater than 90° and less than 120° because when the angle between the top plate 10 and the side plate 11 is 90°, the vertical support force of the bottom support structure 1 is entirely borne by the fixed frame. However, when the angle between the top plate 10 and the side plate 11 is greater than 90°, the vertical support force of the bottom support structure 1 is partially borne by the fixed frame. Under the same support force, the fixed frame is less prone to deformation when the angle between the top plate 10 and the side plate 11 is greater than 90°. When the angle between the top plate 10 and the side plate 11 is 120° or greater, the vertical support force of the bottom support structure 1 is only partially borne by the fixed frame, and the entire hoistway operating frame is prone to tilting away from the fixed frame, which is detrimental to the stability of the entire hoistway operating frame. Therefore, the angle between the top plate 10 and the side plate 11 is greater than 90° and less than 120°.

[0035] Example 10, based on Example 9, provides an integrated hoisting shaft operating frame, such as... Figure 1 As shown, the fixing frame includes a fixing rod 13 and a diagonal rod 14. One end of the fixing rod 13 and the diagonal rod 14 are fixedly connected, and the other end of both the fixing rod 13 and the diagonal rod 14 are connected to the side plate 11, forming a triangular shape. The fixing rod 13 is used to abut against the shaft. During the abutment process, the fixing rod 13 abuts against a horizontal surface of the shaft, and the side plate 11 abuts against a vertical surface of the shaft to ensure the stability of the abutment. In addition, during the abutment process between the fixing rod 13 and the horizontal surface of the shaft, the diagonal rod 14 further supports the fixing rod 13 to ensure the abutment strength of the fixing rod 13. The other end of the fixing rod 13 and the diagonal rod 14 are both connected to the side plate 11, forming a triangular shape, which greatly reduces the possibility of deformation of the fixing frame.

[0036] In Example 10, the base support structure 1, support frame 2, and construction platform 3 of this application are welded together according to the drawings. Then, the base support structure 1, support frame 2, and construction platform 3 are welded and fixed to form a shaft operating frame. Lifting lugs 17 are welded onto the support frame 2. The lifting lugs 17 are then connected using a crane, allowing the shaft operating frame to be hoisted to the required construction position. At this point, the crossbar 13 and side plate 11 on the base support structure 1 abut against the inner wall 18 of the shaft. Then, steel wire ropes 5 are used to connect the three sides of the support frame 2 to the inner wall 18 of the shaft, and the support frame... The other side of the support frame 2 is connected to the inner wall 18 of the shaft by bolts 4, thus completing the fixed installation of the shaft operating frame. When the construction of this layer is completed and other layers need to be constructed, the bolts 4 and wire ropes 5 are removed in sequence. Then, the lifting lugs 17 are connected by a crane so that the shaft operating frame is lifted as a whole to the position where construction is required. Then, the three sides of the support frame 2 are connected to the inner wall 18 of the shaft by wire ropes 5, and the other side of the support frame 2 is connected to the inner wall 18 of the shaft by bolts 4, thus completing the re-fixed installation of the shaft operating frame.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
