[0002] Construction hoist is commonly used in the field of construction, and is responsible for the vertical transportation of goods. It is mainly composed of guide rail frame, cage, trolley frame, guardrail, attached wall and cable guard frame. The guide rail of the traditional construction hoist is generally linear, which cannot meet the construction needs of the curve type buildings such as large bridges and power plants, and most of the curve type buildings are concave curve type. The guide rail frame forms a curve guide rail by using standard sections and increasing shims, but this method is not suitable for convex curves because the standard section rack joint is too large. In addition, the cage angle of the curve type hoist changes constantly with the operation of the cage, and the traditional cage cannot guarantee that the cage bottom plate is always horizontal. Moreover, how to supply power to the power cable becomes a problem as the cage rises. SUMMARY

[0003] In order to overcome the shortcomings of the prior art, the utility model provides a curve construction hoist to solve the problems in the background art.

[0004] In order to achieve the above purpose, the utility model provides the following technical scheme: a curve construction hoist, comprising a cage assembly, a trolley frame assembly, a standard section and an attached wall, the standard section is connected and fixed with the building through the attached wall, the cage assembly is installed on the standard section, the trolley frame assembly is installed on the cage assembly, the cage assembly comprises a floating bottom plate, a screw rod motor, a level sensor and a side flap door, one end of the floating bottom plate is rotatably connected with the lower frame of the cage assembly, the other end is rotatably connected with the driving end of the screw rod motor, the level sensor is arranged on the floating bottom plate, the screw rod motor can drive the floating bottom plate to rotate, the level sensor and the screw rod motor are electrically connected with the controller of the construction hoist, and the side of the cage assembly close to the building is provided with an openable side flap door.

[0007] In the above technical scheme, the floating bottom plate is connected with the lower frame of the cage and the driving end of the screw rod motor through a pin shaft.

[0008] In the above technical scheme, the side flap door is provided with a safety fence close to the outside of the cage assembly.

[0009] In the above technical solution, the lengths of the main chord tubes of the standard section are different, and the length of the main chord tube close to the cage assembly is longer than the length of the main chord tube close to the building.

[0010] The utility model has the advantages of:

[0011] 1. The floating bottom plate can change in real time according to the change of the guide rail curve, so that the floating bottom plate always keeps a horizontal state during the operation of the cage, and the angle adjustment range is 0-16°.

[0012] 2. With the increase of the guide rail frame, the guide rail frame directly forms an outward convex curve, without the need to increase the gasket, so that the problem of too large gap between the rack and the butt joint caused by the gasket is avoided.

DETAILED DESCRIPTION

[0021] The utility model will be further described in combination with the drawings and specific embodiments.

[0022] For example Figure 1The curve construction elevator shown in Figure 5 comprises a cage assembly 2, a trolley frame assembly 3, a standard section 4, and a wall 5. The standard section 4 is connected and fixed to the building through the wall 5, the standard section 4 is installed with the cage assembly 2, and the cage assembly 2 is installed with the trolley frame 3 assembly. The cage assembly 2 comprises a floating bottom plate 7, a screw rod motor 8, a horizontal sensor, and a side flap door 11. One end of the floating bottom plate 7 is rotatably connected to the lower frame 9 of the cage assembly 2, and the other end is rotatably connected to the driving end of the screw rod motor 8. The floating bottom plate 7 is provided with a horizontal sensor. The screw rod motor 8 can drive the floating bottom plate 7 to rotate. The horizontal sensor and the screw rod motor 8 are electrically connected to the controller of the construction elevator. The side of the cage assembly 2 close to the building is provided with an openable side flap door 11.

[0023] When the horizontal sensor detects the angle change of the floating bottom plate, the angle of the floating bottom plate 7 is transmitted to the controller. The controller drives the screw rod motor 8 to rotate the floating bottom plate 7 to the horizontal state.

[0024] When the cage reaches the designated position, the flap door 11 can be opened outward to overlap with the building extension platform, facilitating the entry and exit of construction personnel.

[0025] In the above technical solution, the angle adjustment range of the floating bottom plate 7 is 0-16°.

[0026] In the above technical solution, the standard section 4 is installed with a cable guard 6. One end of the cable guard 6 is connected to the standard section 4, and the other end is in a rectangular structure. The side of the rectangular structure close to the cage assembly 2 is provided with two rubber blocks 14. One end of each rubber block 14 is connected to the side of the rectangular structure of the cable guard. The two rubber blocks are soft and non-connected. That is, the side of the rectangular structure is replaced by the two rubber blocks 14. The cable arm 15 can pass between the two rubber blocks, facilitating the passage of the cable. The side close to the building is installed with a movable roller 13. The roller 13 can roll flexibly. When the inclination angle of the cage is large, the traveling cable will contact the roller 13 of the cable guard 6 and generate friction. The roller 13 can roll flexibly to ensure smooth passage of the cable.

[0027] In the above technical solution, the floating bottom plate 7 is connected to the lower frame 9 of the cage and the driving end of the screw rod motor 8 through a pin shaft 10.

[0028] In the above technical solution, the side flap door 11 is provided with a safety fence 16 close to the outside of the cage assembly 2. The safety fence 16 can improve safety when personnel enter and exit the cage.

[0029] In the above technical solution, the lengths of the plurality of main chord tubes 12 of the standard section 4 are different, and the length of the main chord tube close to the side of the cage assembly 2 is longer than the length of the main chord tube close to the building. The difference in the length of the main chord tube is calculated according to the inclination of the building and can be derived. In the embodiment, the length L1 of the longer main chord tube 12 is 1507.4±0.1, and the length L2 of the shorter main chord tube is 1502±0.1. As the guide rail frame is continuously raised, the entire guide rail frame naturally presents the required convex curve. When a concave guide rail frame is required, only a spacer needs to be added between the main chord tubes close to the building side of the conventional guide rail frame. Since the guide rail frame has straight teeth, when convexity is required, the structure of the utility model can achieve the required requirements.

[0030] The above is only a preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited to this, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model.
