Description

Technical Field

[0001] The present invention belongs to the technical field of stereo garages, and more specifically, relates to a circulating lifting system, a lifting vehicle loading plate and a lifting and transversely moving stereo garage. Background Art

[0002] With the popularization of cars, the demand for parking spaces has also increased rapidly, and traditional garages can no longer meet the demand for parking spaces. Now more and more residential areas, office buildings, and shopping malls have adopted stereo garages, which can store more vehicles in a limited space and have been vigorously promoted and developed.

[0003] In existing stereo garages, the lifting methods for lifting vehicle-mounted plates usually adopt two forms: chain lifting and wire rope lifting. Among them, the chain will make a loud noise during the transmission process, but the anti-swing effect is better. The use of wire rope transmission is quiet and noiseless, but the wire rope is easy to cause the lifting vehicle-mounted plate to swing during the lifting process. At present, both methods are widely used, but whether it is chain lifting or wire rope lifting, the lifting mechanism and the power mechanism are usually installed on the side beams and rear cross beams of the steel structure frame respectively, and then the vehicle-mounted plate is lifted and lowered by chains or wire ropes. This installation method, on the one hand, relies too much on the steel structure frame, which increases the manufacturing cost of the steel structure frame; on the other hand, the chain or wire rope needs to be repeatedly wound, which leads to an increase in cost.

[0004] After searching, the application case with Chinese patent application number 201911135491.X discloses a high-security lifting and transverse moving three-dimensional parking equipment. The application case includes a garage structure frame; a mobile frame, which is arranged on the garage structure frame; a lifting transmission mechanism, which is fixedly connected to the end of the mobile frame; a vehicle loading plate, which is located below the mobile frame, and the steel wire rope connects the vehicle loading plate to the lifting transmission mechanism through four hanging points on the vehicle loading plate; it also includes a rope pressing device, which is fixedly connected to the lifting transmission mechanism to limit the winding rope; a positioning cone, which is in the shape of a long rod, fixedly connected vertically downward to the bottom surface of the mobile frame, and a hole matching the diameter of the positioning cone is opened at the corresponding position on the top surface of the vehicle loading plate. The application case cooperates with the positioning cone to ensure the force balance of the steel wire rope at the four hanging points during the movement of the vehicle loading plate, thereby improving the overall safety of the equipment.

[0005] For another example, the Chinese patent application No. 202122562100.1 discloses a multi-layer lifting and lateral shifting wire rope double-strand co-directional lifting device. The application includes a frame, a lifting motor, a synchronous shaft, a winch drum, a front wire rope, a rear wire rope, a fixed pulley block, an end fixing piece, and a vehicle loading plate. The lifting motor is fixed to the frame, and the synchronous shaft is fixed to the frame through bearing seats arranged at both ends thereof. The lifting motor is configured to drive the synchronous shaft to rotate by a sprocket drive mode, and the two ends of the synchronous shaft are coaxially arranged with the winch drum near the inner side of the bearing seat, respectively. The winch drum is configured to use the front wire rope through the fixed pulley block in a vertical direction to connect to the front of the vehicle loading plate through the end fixing piece, and use the rear wire rope through the fixed pulley block in a vertical direction to connect to the rear of the vehicle loading plate through the end fixing piece.

[0006] Although both of the above two patent documents can realize the lifting operation of the vehicle loading plate and ensure the stability of the vehicle loading plate during the lifting process, in these two patents, the lifting mechanism and the transmission mechanism are both set on the steel structure frame, which leads to excessive load on the steel structure frame and has certain requirements on the strength of the steel structure frame, which is not conducive to reducing costs. Summary of the invention

[0007] 1. Problems to be solved

[0008] In view of at least some of the problems existing in the above-mentioned prior art, the present invention proposes a circulating lifting system, a lifting vehicle plate and a lifting and transversely moving three-dimensional car park, the purpose of which is to solve the problem that the existing vehicle plate lifting system is excessively dependent on the steel structure frame of the garage, and at the same time, the chain or wire rope needs to be repeatedly wound during the lifting process, which is not conducive to cost saving.

[0009] 2. Technical solution

[0010] In order to solve the above problems, the technical solution adopted by the present invention is as follows:

[0011] A circulating lifting system of the present invention comprises a front lifting point chain and a rear lifting point chain, wherein the front lifting point chain is connected to a traction rope after passing through a first reversing assembly, and the rear lifting point chain is connected to the other end of the traction rope after passing through a second reversing assembly, and the traction rope is reversed through a third reversing assembly;

[0012] Among them, the first reversing component and the second reversing component jointly use a double-row power sprocket, which is connected to a driving component. Under the drive of the driving component, the reversing of the reversing component drives the front hanging point chain and the rear hanging point chain to be released or recovered synchronously.

[0013] Furthermore, the first commutation assembly further includes a first steering sprocket, and one end of the front suspension point chain is connected to the towing rope after passing through the first steering sprocket and the double-row power sprocket in sequence.

[0014] Furthermore, the second commutation assembly further includes a second steering sprocket and a third steering sprocket, and one end of the rear suspension point chain is connected to the towing rope after passing through the second steering sprocket, the double-row power sprocket, and the third steering sprocket in sequence.

[0015] Furthermore, the third commutation assembly includes a first guide wheel, a third guide wheel, and a second guide wheel through which the towing rope passes in sequence. Among them, the first guide wheel and the second guide wheel are distributed vertically and offset, and the third guide wheel is arranged on the front suspension point chain.

[0016] Furthermore, an adjusting turnbuckle is provided between the towing rope and the chain.

[0017] Furthermore, the drive assembly includes a motor and a transmission shaft. Among them, the motor is connected to the transmission shaft through chain drive or gear drive, and both ends of the transmission shaft are connected to the double-row power sprocket.

[0018] A lifting car carrier plate of the present invention includes a vehicle-mounted frame and the above-mentioned circulating lifting system, and this circulating lifting system is installed on the vehicle-mounted frame.

[0019] A lifting and traversing three-dimensional garage of the present invention includes a traversing car carrier plate, a steel structure frame, and the above-mentioned lifting car carrier plate. Among them, the ends of the front suspension point chain and the rear suspension point chain of the lifting car carrier plate are fixed on the steel structure frame.

[0020] A lifting and traversing three-dimensional garage of the present invention includes a traversing car carrier plate and the above-mentioned lifting car carrier plate. The lifting car carrier plate is directly suspended from the top of the garage civil structure through the fixed ends of the front suspension point chain and the rear suspension point chain.

[0021] 3. Beneficial effects

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] (1) A cyclic lifting system of the present invention includes a front suspension point chain and a rear suspension point chain. One end of the front suspension point chain is sequentially connected to one end of a towing rope through a first steering sprocket and a double-row power sprocket; one end of the rear suspension point chain is sequentially connected to the other end of the towing rope through a second steering sprocket, a double-row power sprocket and a third steering sprocket, and the towing rope is reversed through a plurality of guide wheels; by driving the double-row power sprocket, under the action of the steering sprocket and the guide wheels, the synchronous release or recovery of the front suspension point chain and the rear suspension point chain is realized, so as to complete the lifting operation of the car carrier board. Compared with the traditional lifting system, the lifting system of the present invention adopts a cyclic lifting method, which can reduce the amount of chain used, thus achieving the purpose of cost saving. At the same time, in the whole cyclic lifting system, the towing rope only plays the role of reversing and extending the moving path of the chain, and is basically not stressed, which can extend the service life of the steel wire rope, and further saves costs.

[0024] (2) A car carrier board of the present invention is directly installed on the vehicle frame and lifted synchronously with the vehicle frame; compared with the traditional lifting system, the lifting mechanism needs to be installed on the side beam of the steel structure frame, and the driving structure is installed on the rear cross beam of the steel structure frame; the present invention can install the whole lifting system on the vehicle frame, so that the rear cross beam no longer bears the lifting torque, the material used for the rear cross beam can be reduced, and the cost can be reduced. In addition, in an underground parking lot with a civil engineering structure, the front and rear suspension point chains can be directly fixed on the top of the civil engineering structure without a steel structure frame. It can not only reduce the erection cost of the steel structure frame, but also greatly save the space of the parking lot. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The present invention will be further described below in conjunction with specific embodiments.

[0042] Embodiment 1

[0043] Combined with Figure 1 、 Figure 2 As shown, a cyclic lifting system in this embodiment includes a front suspension point chain 11, a rear suspension point chain 12, and a towing rope 13 connecting the front and rear suspension point chains.

[0044] One end of the towing rope 13 is connected after the front suspension point chain 11 is reversed by the first commutation assembly; the other end of the towing rope 13 is connected after the rear suspension point chain 12 is reversed by the second commutation assembly; and the towing rope 13 also needs to be connected to the front and rear suspension point chains after being reversed by the third commutation assembly. At the same time, an adjusting turnbuckle 14 is provided between the towing rope 13 and the front and rear suspension point chains to adjust the tightness of the chain and ensure the transmission efficiency and safety.

[0045] Among them, the first commutation component and the second commutation component share a double-row driving sprocket 21, which can ensure the synchronization of the movement between the front suspension point chain 11 and the rear suspension point chain 12, and is beneficial to ensuring the stability of the lifting process. The double-row driving sprocket 21 is connected with a driving component 5. Driven by the driving component 5, through the transmission of the double-row driving sprocket 21 and the commutation of each commutation component, the front suspension point chain 11 and the rear suspension point chain 12 are driven to be synchronously released or recovered, so as to complete the lifting operation of the car carrier board.

[0046] Specifically, the first commutation component includes a double-row driving sprocket 21 and a first steering sprocket 22. One end of the front suspension point chain 11 is sequentially connected to a towing rope 13 after passing through the first steering sprocket 22 and the double-row driving sprocket 21.

[0047] Reference Figure 3 As shown, the second commutation component includes a second steering sprocket 31, a third steering sprocket 32 and a double-row driving sprocket 21. One end of the rear suspension point chain 12 is sequentially connected to a towing rope 13 after passing through the second steering sprocket 31, the double-row driving sprocket 21 and the third steering sprocket 32.

[0048] Reference Figures 4 - 5 As shown, the third commutation component includes a first guide wheel 41, a second guide wheel 42 and a third guide wheel 43. The towing rope 13 sequentially passes through the first guide wheel 41, the third guide wheel 43 and the second guide wheel 42.

[0049] Among them, the first guide wheel 41 and the second guide wheel 42 are vertically and staggeredly distributed, and are located between the double-row driving sprocket 21 and the first steering sprocket 22, close to the first steering sprocket 22. The third guide wheel 43 is located between the first guide wheel 41 and the double-row driving sprocket 21, and is horizontally arranged on the front suspension point chain 11 between the first steering sprocket 22 and the double-row driving sprocket 21.

[0050] A cyclic lifting system according to this embodiment, through the setting of the double-row power sprockets 21, although the synchronization of the movement of the front and rear suspension point chains is ensured. However, it also causes a certain dislocation between the front and rear suspension point chains, and they are not in the same vertical plane, which is not conducive to the direct commutation between the front and rear suspension point chains. In this embodiment, through the setting of the towing rope 13 and the mutual cooperation of the first guide wheel 41, the second guide wheel 42 and the third guide wheel 43, not only the flexible connection between the front and rear suspension point chains is realized to facilitate commutation; at the same time, it also helps to extend the moving path of the chain. On the basis of ensuring to meet a certain lifting height requirement, the use length of the chain can be reduced as much as possible, so as to achieve the purpose of cost saving. In addition, the towing rope 13 in the entire cyclic lifting system only plays the role of flexible commutation and extending the moving path of the chain, and is basically not stressed. On the premise of ensuring its service life, ordinary steel wire ropes can be used, which can further save costs.

[0051] Reference Figure 6 、 Figure 7 As shown, the drive assembly 5 includes a motor 51 and a transmission shaft 52. Among them, the motor 51 and the transmission shaft 52 are connected by chain drive or gear drive, and both ends of the transmission shaft 52 are connected to the double-row power sprockets 21. Through the drive of the motor 51, the double-row power sprockets 21 can be driven to rotate clockwise and counterclockwise, so as to realize the synchronous release or recovery of the front suspension point chain 11 and the rear suspension point chain 12.

[0052] Embodiment 2

[0053] A lifting car carrier plate according to this embodiment includes a vehicle-mounted frame 61 and a lifting system provided on the vehicle-mounted frame 61. Among them, the lifting system is the cyclic lifting system described in Embodiment 1.

[0054] Specifically, as shown in reference Figure 7 、 Figure 8 The drive assembly 5 is arranged at the end of the vehicle-mounted frame 61; each commutation assembly is arranged on both sides of the vehicle-mounted frame 61, so that the entire lifting system and the lifting car carrier plate are integrated and can move up and down synchronously.

[0055] The working principle of a lifting car carrier plate according to this embodiment is as follows:

[0056] The motor 51 drives the transmission shaft 52 to rotate, and the transmission shaft 52 drives the double-row power sprockets 21 at both ends to rotate synchronously. Since the inner row of the double-row power sprockets 21 is wound with the rear suspension point chain 12 and the outer row is wound with the front suspension point chain 11, when the double-row power sprockets 21 rotate clockwise, the front and rear suspension point chains are released simultaneously, and the vehicle-mounted plate can be driven to move downward; when the double-row power sprockets 21 rotate counterclockwise, the front and rear suspension point chains are retracted simultaneously, thereby driving the vehicle-mounted plate to move upward.

[0057] When in the retracted state, the front and rear suspension point chains are stored inside the side beams of the vehicle-mounted frame 61. At the same time, the drive assembly 5 is located at one end of the vehicle-mounted frame 61 away from the entrance. This makes the overall structure compact, occupies a small space, and does not interfere with the normal entry of the vehicle.

[0058] For the lifting vehicle-carrying board of this embodiment, the overall lifting is carried out by chains. During the lifting process of the vehicle-carrying board, it is not easy to swing and has good stability. In addition, steel wire ropes are used to connect and reverse the front and rear suspension point chains. Through the steel wire ropes, two vertical plane turns and one horizontal plane turn are carried out to realize the cyclic movement of the front and rear suspension point chains in different planes, and the noise is relatively low.

[0059] Embodiment 3

[0060] As Figure 9 、 Figure 10 shown, this embodiment also provides a lifting and traversing three-dimensional garage, which includes a lifting vehicle-carrying board 6, a traversing vehicle-carrying board 7, and a steel structure frame 8. Among them, the lifting vehicle-carrying board 6 is the lifting vehicle-carrying board described in Embodiment 2, and the lifting vehicle-carrying board 6 is suspended on the steel structure frame 8 through the ends of the front suspension point chain 11 and the rear suspension point chain 12.

[0061] Compared with the traditional three-dimensional garage, the lifting mechanism of the lifting system needs to be installed on the side beam of the steel structure frame 8, and the drive structure is installed on the rear cross beam of the steel structure frame 8; in the present invention, the entire lifting system can be installed on the vehicle-mounted frame 61, so that the rear cross beam no longer bears the lifting torque, the material used for the rear cross beam can be reduced, and the cost can be lowered.

[0062] In addition, in an underground parking lot with a civil engineering structure, the front and rear suspension point chains can be directly fixed to the top of the civil engineering structure without the steel structure frame 8. This can not only reduce the erection cost of the steel structure frame 8, but also greatly save the space of the parking lot.

[0063] The above schematically describes the present invention and its embodiments. This description is not restrictive. What is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if those of ordinary skill in the art are inspired by it and design a structural manner and an embodiment similar to this technical solution without creative work without departing from the purpose of the present invention, they shall fall within the protection scope of the present invention.
