Description

Technical Field

[0001] The invention relates to the technical field of three-dimensional garages, in particular to a traction-type off-center loading automobile car cabin. Background Art

[0002] As an important equipment of the stereo garage, the elevator is responsible for moving vehicles from the 1st floor to different heights, and moving vehicles from different floors to the 1st floor. On this basis, in order to further improve the operating efficiency of the stereo garage, a car-type elevator has emerged. There are multiple parking spaces on the car, and a transport trolley is arranged on it. The vehicle can be moved horizontally and rotated while the elevator is lifting. In this way, when the elevator reaches the designated floor, the vehicle reaches the designated parking space and posture at the same time, and no horizontal movement or rotation is required. Therefore, the operation time is effectively saved and the operating efficiency of the stereo garage is improved.

[0003] At present, this type of car is generally hoisted by chain, because during the hoisting process, when the vehicle rotates or moves horizontally, the car is subjected to a relatively large eccentric load. The chain as a forced drive method can effectively overcome the additional bending moment caused by the eccentric load, thereby overcoming the overturning tendency of the car. However, the disadvantage of chain hoisting is that the speed is slow and cannot meet the lifting speed requirements of high-rise stereo garages. Summary of the invention

[0004] The technical problem to be solved by the present invention is that the existing elevator cars are generally chain-lifted, but the chain lifting speed is slow and cannot meet the demand for elevator lifting speed in high-rise stereo garages.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A traction-type offset-load automobile car, comprising a car floor and a loading platform coupled to the upper end thereof, a transport trolley being arranged on the loading platform, the car floor being a rectangular frame jointly constituted by two groups of first trusses and two groups of second trusses, traction wheels being symmetrically arranged at both ends of the outer sides of the first trusses, and the traction wheels being transmission-connected to an external elevator lifting device; a vertically arranged guide arm being integrally arranged at a right angle to the rectangular frame, and guide devices being symmetrically arranged at the upper and lower ends of the guide arm; a limiting guide rail matching the guide device is correspondingly arranged on the inner wall of the elevator shaft where the car floor runs, and the limiting guide rail is vertically arranged; the guide device comprises a mounting seat fixed to the guide arm, the mounting seat being provided with an open groove for the limiting guide rail to pass through, the mounting seat being provided with three groups of guide wheels respectively rollingly matched with the three side surfaces of the limiting guide rail, and the guide wheels being fixed to the mounting seat through a mounting frame.

[0007] As a further solution of the present invention: the first truss includes a first upper chord and a first lower chord arranged horizontally, a plurality of first vertical poles are arranged between the first upper chord and the first lower chord, a first diagonal web member is arranged between adjacent first vertical poles, and a triangular structure is formed between the first vertical poles, the first diagonal web member and the first upper chord or the first lower chord.

[0008] As a further solution of the present invention: adjacent first diagonal web members are arranged symmetrically.

[0009] As a further solution of the present invention: a plurality of third trusses are further arranged between the first uprights.

[0010] As a further solution of the present invention: the second truss and the third truss each include two groups of horizontally arranged second chord rods, and a plurality of second vertical rods arranged at intervals are provided between the second chord rods.

[0011] As a further solution of the present invention: the second chord above the second truss is flush with the first upper chord.

[0012] As a further solution of the present invention: a first reinforcing rod is arranged between the second chord rod below the second truss and the guide arm, and a triangular structure is formed between the guide arm, the second chord rod and the first reinforcing rod.

[0013] As a further solution of the present invention: the second chord below the third truss is flush with the first lower chord.

[0014] As a further solution of the present invention: both ends of the second chord of the third truss are fixed to the first vertical pole of the first truss, a second reinforcing rod is arranged between the second chord above the third truss and the first vertical pole, and a triangular structure is formed between the first vertical pole, the second chord and the second reinforcing rod.

[0015] As a further solution of the present invention: a maintenance platform is arranged between the two groups of first trusses located on one side of the second truss, and the maintenance platform is arranged lower than the upper end surface of the first truss.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. Through the traction lifting method, the lifting speed of the multi-parking car is faster, meeting the demand for elevator lifting speed in high-rise stereo garages.

[0018] 2. Through the setting of the guide device and the limit guide rail, the overturning bending moment caused by the eccentric load is converted into a positive pressure acting on the limit guide rail through the guide wheel, overcoming the large eccentric load and avoiding overturning, realizing eccentric load lifting, meeting the needs of vehicle lateral movement or rotation when lifting a multi-parking car, and then adjusting the parking space and posture while lifting, effectively saving operating time and improving the operating efficiency of the stereo garage.

[0019] 3. The integrated space truss structure design effectively improves the rigidity while greatly reducing the weight of the entire car and the load on the traction sheave, thereby reducing costs and increasing the lifting speed.

[0020] In summary, the present invention can achieve the offset lifting of multi-parking car cabins by traction, effectively saving operation time and improving the operation efficiency of the stereo garage; while effectively improving the rigidity, it greatly reduces the weight of the entire car, thereby reducing costs.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] See also Figure 1-2A traction-type car car with partial load, comprising a car floor and a loading platform (not shown) connected to the upper end thereof, a transport trolley (not shown) being arranged on the loading platform (not shown), the car floor being a rectangular frame body composed of two groups of first trusses 1 and two groups of second trusses 3, traction wheels 5 being symmetrically arranged at both ends of the outer side of the first trusses 1, the traction wheels 5 being drivingly connected to an external elevator lifting device (not shown); a vertically arranged guide arm 2 being integrally arranged at a right angle to the rectangular frame, the guide arm 2, guide devices 4 are symmetrically arranged at the upper and lower ends; a limit guide rail 8 matching the guide device 4 is correspondingly arranged on the inner wall of the elevator shaft where the car bottom plate runs, and the limit guide rail 8 is arranged vertically; the guide device 4 includes a mounting seat 41 fixed to the guide support arm 2, and the mounting seat 41 is provided with an opening groove 44 for the limit guide rail 8 to pass through, and the mounting seat 41 is provided with three groups of guide wheels 43 respectively rolling with the three side surfaces of the limit guide rail 8, and the guide wheels 43 are fixed to the mounting seat 41 through a mounting frame 42.

[0026] The working principle of the present invention is: through the traction lifting mode, the lifting speed of the multi-parking car is faster, meeting the demand of the high-rise three-dimensional parking garage for the lifting speed of the elevator.

[0027] Through the setting of the guide device 4 and the limiting guide rail 8, the overturning bending moment caused by the eccentric load is converted into a positive pressure acting on the limiting guide rail 8 through the guide wheel 43, thereby overcoming the large eccentric load and avoiding overturning, realizing eccentric load lifting, and meeting the needs of vehicle lateral movement or rotation when lifting a multi-parking car, and then the parking space and posture can be adjusted during lifting, which effectively saves operating time and improves the operating efficiency of the multi-story parking garage.

[0028] The integrated space truss structure design effectively improves the rigidity while greatly reducing the weight of the entire car and the load on the traction sheave, thereby reducing costs and increasing the lifting speed.

[0029] In actual use, the first upper chord is both the hanging beam of the traction wheel and the load-bearing beam of the loading platform, and also the bending-resistant beam of the car floor. Therefore, as long as it is made of higher-strength materials, it can reduce costs while meeting the strength requirements of the entire car.
