Description

Technical Field

[0001] The utility model belongs to the technical field of stereoscopic garages, and particularly relates to a rear cantilever hydraulic drive stereoscopic vehicle. Background Technique

[0002] With the high development of China's economy and the automotive industry, the per capita car ownership is increasing, while the number of parking spaces is growing slowly, and the urban parking problem is becoming more and more prominent. Parking difficulty has become a common problem in cities. Therefore, cities have vigorously introduced stereoscopic parking equipment to alleviate the urban parking difficulty problem. The rear cantilever stereoscopic garage has a simple structure and low manufacturing cost, and is especially suitable for the transformation of ground parking spaces, which largely solves the problem of parking difficulty caused by the shortage of parking spaces in old communities.

[0003] The existing rear cantilever stereoscopic garages have two structures: chain type and hydraulic type. Among them, the hydraulic rear cantilever stereoscopic garage needs to use hydraulic cylinders to drive the upper car-carrying plate to lift. In order to save costs, each upper car-carrying plate uses one hydraulic cylinder. The top of the piston rod of the hydraulic cylinder is installed with two movable pulleys, which respectively drive two lifting steel wires. The two lifting steel wires respectively lift the left and right sides of the car-carrying plate. However, during the lifting process, due to the uneven force on the two steel wires, the forces on the two movable pulleys are different, which causes the piston rod of the hydraulic cylinder to deflect, easily causing the steel wire to break away from the movable pulley and affecting the normal use of the stereoscopic garage.

[0004] Therefore, in the technical field of stereoscopic garages, there is still a need for research and improvement on the rear cantilever hydraulic drive stereoscopic vehicle. This is also a research hot spot and key point in the current technical field of stereoscopic garages, and it is also the starting point for the completion of the present utility model. Content of the Utility Model

[0005] For this reason, the technical problem to be solved by the present utility model is: to provide a rear cantilever hydraulic drive stereoscopic vehicle to solve the technical problem that the piston rod of the hydraulic cylinder deflects, resulting in the steel wire being easily disengaged from the movable pulley.

[0006] To solve the above technical problem, the technical solution of the present utility model is: a rear cantilever hydraulic drive stereoscopic vehicle, including two columns arranged opposite to each other at intervals. A sliding seat is vertically slidably installed on the column, and the sliding seat is fixedly connected to a lifting car-carrying plate. A hydraulic cylinder is provided on one of the columns, the cylinder body of the hydraulic cylinder is fixed to the column, the top of the piston rod of the hydraulic cylinder is fixedly installed with a pulley seat, two groups of movable pulleys are rotatably installed on the pulley seat, the two groups of movable pulleys are respectively connected to two groups of lifting steel wires, one end of the lifting steel wire is fixed to the column, and the other end is fixed to the sliding seat after passing around the corresponding movable pulley. A vertically arranged guide post is fixedly installed on the column, a guide sleeve is fixedly installed on the pulley seat, and the guide sleeve is slidably installed on the guide post.

[0007] As an improvement, two guiding columns are arranged at intervals, and the two guiding columns are arranged in parallel.

[0008] As a further improvement, the extending direction of the piston rod of the hydraulic cylinder is downward.

[0009] As a further improvement, the column is an H-shaped steel, and a strengthening member is arranged on the outer side of the flange of the column, and the extending direction of the strengthening member is consistent with the extending direction of the flange.

[0010] After adopting the above technical solution, the beneficial effects of the present utility model are as follows:

[0011] In the rear cantilever hydraulic-driven stereo vehicle provided by the embodiment of the present utility model, a vertically arranged guiding column is fixedly installed on the column, and the pulley seat is slidably installed on the guiding column. When the lifting steel wires on both sides are unevenly stressed, the guiding column can bear the force acting on the pulley seat, reduce the deflection amount of the pulley seat, avoid the lifting steel wire from disengaging from the movable pulley, and improve the safe use performance of the present utility model.

[0012] Since two guiding columns are arranged at intervals, the pulley seat can only slide vertically and cannot deflect, thereby avoiding the lifting steel wire from disengaging from the movable pulley and further improving the safe use performance of the embodiment of the present utility model.

[0022] Such as Figure 1As shown in the figure, a rear cantilever hydraulically driven three-dimensional vehicle includes two columns 1 arranged opposite to each other at intervals. The two columns 1 are arranged in parallel. Usually, a cross beam is arranged between the two columns 1 to ensure the stability of the columns 1. A sliding seat 2 is vertically slidably installed on the column 1. The sliding seat 2 is fixedly connected to a lifting car carrier plate 3. A hydraulic cylinder 5 is provided on one of the columns 1. The cylinder body of the hydraulic cylinder 5 is fixed on the column 1. The extending direction of the piston rod of the hydraulic cylinder 5 is downward. The top end of the piston rod of the hydraulic cylinder 5 is fixedly installed with a pulley seat 6. Two groups of movable pulleys 7 are rotatably installed on the pulley seat 6. In the vehicle driving direction, the two groups of movable pulleys 7 are arranged front and back. The two groups of movable pulleys 7 are respectively connected to two groups of lifting steel wires. One end of the lifting steel wire is fixed on the column 1, and the other end is fixed on the sliding seat 2 after passing around the corresponding movable pulley 7. Of course, those skilled in the art can set steering wheels at the positions where steering is required according to needs, and those skilled in the art can set them by themselves according to needs, which will not be elaborated here. By the telescopic movement of the piston rod of the hydraulic cylinder 5, the pulley 7 seat 6 is driven to rise and fall, so that the lifting car carrier plate 3 rises and falls, realizing the access of the upper-layer vehicle. When N rows of parking spaces are arranged horizontally, N is greater than or equal to 2. Usually, N - 1 transverse car carrier plates 4 are arranged on the ground floor. A vacant parking space is left under one of the lifting car carrier plates 3 to meet the access of the lifting car carrier plate 3 to the vehicle. A vertically arranged guide post 8 is fixedly installed on the column 1. A guide sleeve 9 is fixedly installed on the pulley seat 6. The guide sleeve 9 is slidably installed on the guide post 8. When the forces on the two sides of the lifting steel wires are uneven, the guide post 8 can bear the force acting on the pulley seat 6, reducing the deflection amount of the pulley seat 6 and avoiding the lifting steel wire slipping out of the movable pulley 7.

[0023] Furthermore, as Figure 2 and Figure 3 shown, there are two guide posts 8 arranged at intervals. The two guide posts 8 are arranged in parallel. Correspondingly, two guide sleeves 9 fixed on the pulley seat 6 are also provided, so that the pulley seat 6 can only slide vertically and cannot deflect, thus avoiding the lifting steel wire slipping out of the movable pulley 7 and improving the service performance of the present utility model.

[0024] The column 1 is an H-shaped steel. Rollers and guide wheels are installed on the sliding seat 2. The rollers abut against the inner side of the flange of the column 1, and the guide wheels abut against the web. Therefore, the acting force of the lifting car carrier plate 3 acts on the flange of the column 1. After long-term use, the flange of the column 1 will be deformed, resulting in unstable lifting of the lifting car carrier plate 3. Therefore, as Figure 4 shown, a strengthening member 10 is provided on the outer side of the flange of the column 1. The extending direction of the strengthening member 10 is the same as that of the flange. The strengthening member 10 is usually a C-shaped bending plate or other shaped profiles, welded on the outer side of the flange, playing a role in strengthening the strength and rigidity and extending the service life of the column 1.

[0025] Although the present utility model has been described in detail with general descriptions and specific embodiments above, modifications or improvements can be made thereto based on the present utility model, which will be obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present utility model all fall within the scope of protection required by the present utility model.
