Description

Technical Field

[0001] The present invention belongs to mechanical parking devices, and particularly relates to a small parking equipment for lifting and traversing vehicles. Background Art

[0002] It is a very common practice to set up parking spaces on the roadside within a road. However, on the roadside of some roads with a lane width of only about three meters, it is impossible to set up parking spaces. On the roadside with a width of four or five meters, it may also be restricted by the traffic management department and not allowed to set up road surface parking spaces. On the roadside with a width of seven or eight meters, although it may be allowed to set up parking spaces on one side of the roadside, in order to meet two-way traffic, it is generally prohibited to set up parking spaces on the other side of the road.

[0003] In order to obtain roadside parking spaces under the above-mentioned conditions, in Chinese Patent CN204060070U, a solution is disclosed that can directly lift the car carrier plate from the ground to more than two meters above the road surface. Although this solution can still allow people and vehicles to pass under the suspended car carrier plate, there are still potential safety hazards for pedestrians and vehicles to pass under the suspended car carrier plate of the equipment, and relevant regulations in some countries may not allow this kind of equipment to be installed on the roadside of public roads.

[0004] Chinese Patent CN205476723U discloses a small overhead parking equipment that can move the car carrier plate from the roadside to the road. A front leg is provided under the front corner of the front shift frame for carrying the car carrier plate, a bottom wheel is provided at the bottom of the front leg, and a rear wheel is provided at the rear of the front shift frame. When the front shift frame moves forward, its front wheel moves on the road surface, and its rear wheel moves on the overhead guide rail on the upper part of the fixed frame. Although this solution can use the space above the sidewalk or green space outside the road for parking, in order to make the bottom wheel of its front leg move smoothly, a ground rail needs to be laid on the driving road surface, and the foundation engineering is difficult. And through actual verification, during the movement of its front leg on the ground, not only is it easy to form overall shaking, but it is also easily blocked by ground debris, posing a threat to the safety of surrounding people and vehicles. Therefore, in some countries, it may not be allowed to be arranged in public places. Summary of the Invention

[0005] In order to solve the above-mentioned defects of the prior art, the present invention proposes a roadside overhead parking equipment with a car carrier plate that can move forward and lift, as shown in the attached drawings. Its unique features are as follows:

[0006] It includes a fixed frame 1 and a forward shift frame 2.

[0007] The fixed frame 1 includes fixed frame longitudinal guide beam 12 at the left and right side parts, fixed frame front cross beam 13 at the front part, and fixed frame rear cross beam 14 at the rear part.

[0008] Below the middle of each fixed frame longitudinal guide rail beam 12, there is a single fixed frame column 11, and the bottom end of the single fixed frame column 11 is fixed to the ground;

[0012] The forward movement frame longitudinal guide rail beam 21 includes a forward movement frame longitudinal guide rail beam downward-facing rail surface 211 with a main guiding surface facing downward;

[0013] The forward movement frame longitudinal guide rail beams 21 on the left and right sides of the forward movement frame 2 are located between the fixed frame longitudinal guide rail beams 12 on the left and right sides of the fixed frame 1;

[0015] Driven by the forward movement mechanism, the forward movement frame 2 can reciprocate back and forth between the front limit position and the rear limit position,

[0016] During the reciprocating back and forth translation of the forward movement frame 2, the forward movement frame longitudinal guide rail beam rear guide wheel 212 is limited and guided by the fixed frame longitudinal guide rail beam downward-facing rail surface 121 and the fixed frame longitudinal guide rail beam upward-facing rail surface 122;

[0017] During the reciprocating back and forth translation of the forward movement frame 2, the forward movement frame longitudinal guide rail beam downward-facing rail surface 211 is supported and guided by the fixed frame longitudinal guide rail beam front guide wheel 124;

[0018] Inside the hollow area of the forward movement frame 2, there is a vehicle-carrying plate 3,

[0019] Four lifting rope chains 31 led downward from the rope chain lifting mechanism arranged on the forward movement frame front cross beam 22 and the forward movement frame rear cross beam 23 are suspended on the side beams of the vehicle-carrying plate 3,

[0020] When the forward movement frame 2 moves to the rear limit position, the vehicle-carrying plate 3 that has risen to the upper limit position is located above the fixed frame front cross beam 13;

[0021] When the forward movement frame 2 moves to the front limit position, the rope chain lifting mechanism can release the lifting rope chains 31 to lower the vehicle-carrying plate 3 to the road surface 51 to pick up and drop off the vehicle 4.

[0022] Preferably,

[0023] At the front of each longitudinal guide beam 21 of the forward movement frame, a front sprocket 214 of the longitudinal guide beam of the forward movement frame is provided, and at the rear, a rear sprocket 213 of the longitudinal guide beam of the forward movement frame is provided;

[0024] The front sprocket 214 of the longitudinal guide beam of the forward movement frame and the rear sprocket 213 of the longitudinal guide beam of the forward movement frame are connected by a forward movement chain 215 of the forward movement frame;

[0025] The two rear sprockets 213 of the longitudinal guide beam of the forward movement frame rotate synchronously under the drive of the forward movement mechanism;

[0026] The fixed frame 1 is provided with a forward movement chain connecting body 132 connected to the forward movement chain 215 of the forward movement frame.

[0027] Preferably,

[0028] The forward movement mechanism includes a forward movement drive shaft 24 of the forward movement frame arranged behind the rear cross beam 23 of the forward movement frame,

[0029] The rear sprocket 213 of the longitudinal guide beam of the forward movement frame is fixedly connected to the forward movement drive shaft 24 of the forward movement frame.

[0030] Preferably,

[0031] The shaft hole of the rear sprocket 213 of the longitudinal guide beam of the forward movement frame and the shaft hole of the rear guide wheel 212 of the longitudinal guide beam of the forward movement frame are both penetrated by the forward movement drive shaft 24 of the forward movement frame;

[0032] The rear guide wheel 212 of the longitudinal guide beam of the forward movement frame is slidably connected to the forward movement drive shaft 24 of the forward movement frame.

[0033] Preferably,

[0034] When the forward movement frame 2 moves forward to the front limit position, the distance between the front vertical surface of the longitudinal guide beam 12 of the fixed frame and the axis of the rear guide wheel 212 of the longitudinal guide beam of the forward movement frame should not be less than 0.5 meters;

[0035] The distance between the front vertical surface of the front cross beam 13 of the fixed frame and the front vertical surface of the single vertical column 11 of the fixed frame should not be greater than 0.35 meters.

[0036] Preferably,

[0037] A shed cover 25 of the forward movement frame is installed on the upper part of the forward movement frame 2.

[0038] Compared with the prior art, the car carrier board in the present invention in the raised and homing state is reliably protected by the frame structure of the fixed frame below, and it is completely impossible for the vehicle and the car carrier board to fall, completely eliminating the potential safety hazards of people and vehicles in the space below, and achieving ideal equipment safety performance. When implementing the present invention, only two column footing pit foundations need to be arranged on the ground outside the roadside, and there is no need to excavate and install equipment components such as ground rails in the road surface, which is more convenient for on-site construction and installation. The present invention not only realizes the purpose of using the space above the roadside for parking, but also, the central single-column structure can minimize the occupation of the ground and the spatial interference to pedestrians or plants on the ground. When arranged between the lane and the sidewalk, the overhead fixed frame and the forward moving frame can serve as a rain shelter and a sunshade above the sidewalk. When arranged between the lane and the roadside green space, the overhead structure more than two meters has little impact on the light reception of the green plants below. The equipment shape of the overhead pavilion is more easily integrated into the surrounding landscape and better meets the requirements of urban environmental beautification. Compared with the prior art, the component structure and the transmission mechanism of the present invention are simpler, and the synchronous and stable lateral movement of the forward moving frame is realized only by two sets of sprocket chains, providing ideal conditions for low-cost production. The forward moving frame canopy arranged on the forward moving frame can provide a more comprehensive function of shading and rain protection for the vehicle.

[0077] The embodiment of the present invention is shown in the attached drawings. This is a roadside overhead parking equipment with a movable and liftable carriage plate designed according to the principle of the present invention.

[0078] See Figure 1 , this equipment includes a fixed frame 1, a forward movement frame 2 and a carriage plate 3 arranged inside the forward movement frame 2.

[0079] The structure of the fixed frame 1 is as Figure 2 shown. It includes fixed frame longitudinal guide rail beams 12 located on the left and right sides, a front cross beam 13 of the fixed frame at the front, and a rear cross beam 14 of the fixed frame at the rear. Between the front cross beam 13 of the fixed frame and the rear cross beam 14 of the fixed frame, two middle longitudinal beams 15 of the fixed frame are provided.

[0080] Below the middle of each fixed frame longitudinal guide rail beam 12, a single fixed frame column 11 is provided, and the bottom end of the single fixed frame column 11 is fixed to the ground.

[0081] See Figure 2 for the partial enlarged view. The fixed frame longitudinal guide rail beam 12 includes a lower guide rail surface 121 of the fixed frame longitudinal guide rail beam with the main guiding surface facing downwards and an upper guide rail surface 122 of the fixed frame longitudinal guide rail beam with the main guiding surface facing upwards. At the front end of each fixed frame longitudinal guide rail beam 12, a front guide wheel 124 of the fixed frame longitudinal guide rail beam is provided.

[0082] See Figure 3 andFigure 4 , the forward shift frame 2 includes forward shift frame longitudinal guide beam 21 on the left and right sides. Between the front ends of the left and right forward shift frame longitudinal guide beams 21, there is a forward shift frame front cross beam 22, and between the rear parts of each forward shift frame longitudinal guide beam 21, there is a forward shift frame rear cross beam 23.

[0083] At the front of each forward shift frame longitudinal guide beam 21, there is a forward shift frame longitudinal guide beam front sprocket 214, and at the rear, there is a forward shift frame longitudinal guide beam rear sprocket 213. The left and right forward shift frame longitudinal guide beam rear sprockets 213 are fixedly installed on both ends of the sides of the forward shift frame forward drive shaft 24 located behind the forward shift frame rear cross beam 23. The left and right forward shift frame longitudinal guide beam rear guide wheels 212 are installed at both ends of the forward shift frame forward drive shaft 24 by means of bearings.

[0084] The front sprocket 214 of the forward shift frame longitudinal guide beam on each side and the rear sprocket 213 of the forward shift frame longitudinal guide beam are connected by a closed-loop forward shift frame forward chain 215.

[0085] See Figure 4 For the partial enlarged view of, the forward shift frame longitudinal guide beam 21 includes a forward shift frame longitudinal guide beam lower rail surface 211 with the main guiding surface facing downwards.

[0086] See Figure 2 For the partial enlarged view of, the fixed frame 1 is provided with a forward chain connecting body 132 connected to the forward shift frame forward chain 215.

[0087] See Figure 5 , after the equipment is assembled, the forward shift frame longitudinal guide beams 21 on the left and right sides of the forward shift frame 2 are located between the fixed frame longitudinal guide beams 12 on the left and right sides of the fixed frame 1;

[0088] The forward shift mechanism located outside the middle of the forward shift frame rear cross beam 23 can drive the forward shift frame forward drive shaft 24 to rotate according to the instruction, driving the forward shift frame forward chain 215 to run. As Figure 5 Shown in the partial enlarged view of, because one link at the corresponding position of the two forward shift frame forward chains 215 is fixedly connected to the forward chain connecting body 132 on the limit stop blocks 131 at both ends of the fixed frame front cross beam, when the forward shift frame forward chain 215 reciprocates and rotates, it will drive the forward shift frame 2 to reciprocate between the front limit position and the rear limit position.

[0089] See Figure 6 For the partial enlarged view of, during the reciprocating translation of the forward shift frame 2 back and forth, the forward shift frame longitudinal guide beam lower rail surface 211 is supported and guided by the front guide wheels 124 of the fixed frame longitudinal guide beam;

[0090] Figures 7 to 10 Shows the lifting process of the car carrier 3 during the operation of the equipment.

[0091] As Figure 7As shown in the partial enlarged view, when the front moving frame 2 moves to the front limit position, the rear cross beam 23 of the front moving frame will be blocked by the limit stop block 131 of the front cross beam of the fixed frame.

[0092] Four lifting rope chains 31 led downward from the rope chain lifting mechanism arranged on the front cross beam 22 and the rear cross beam 23 of the front moving frame are suspended on the side beams of the car carrier plate 3. When the front moving frame 2 moves to the front limit position, the rope chain lifting mechanism can release the lifting rope chains 31 to lower the car carrier plate 3.

[0093] See Figure 11 , when the car carrier plate 3 descends to the road surface, the vehicle 4 can drive straight in and out of the car carrier plate 3.

[0094] See Figure 12 , in order to ensure that the front moving frame 2 carrying a large load and suspended can maintain a reasonable stress condition, when the front moving frame 2 moves forward to the front limit position, the distance A between the front vertical surface of the fixed frame longitudinal guide beam 12 and the axis of the rear guide wheel 212 of the front moving frame longitudinal guide beam should not be less than 0.5 meters. In this embodiment, this distance is set to 0.86 meters.

[0095] When the vehicle to be stored needs to enter the car carrier plate 3, it is obvious that the vehicle body is expected not to be too close to the fixed frame single column 11. Therefore, in order to prevent the distance C between the landed car carrier plate 3 and the fixed frame single column 11 from being too narrow, the distance B between the front vertical surface of the front cross beam 13 of the fixed frame and the front vertical surface of the fixed frame single column 11 should not be greater than 0.35 meters. In this embodiment, this distance is set to 0.55 meters.

[0096] See Figure 2 、 Figure 13 and Figure 14 , when the car carrier plate 3 rises to the upper limit position and the front moving frame 2 retracts to the rear limit position, the whole car carrier plate 3 is above the anti-fall structure jointly formed by the front cross beam 13 of the fixed frame and the middle longitudinal beam 15 of the fixed frame. Therefore, even if all the lifting rope chains 31 are disconnected at this time, the car carrier plate 3 will be reliably supported by the anti-fall structure and cannot fall. This safety measure replaces the electric control anti-fall device often used in traditional parking equipment, reducing the cost while ensuring higher reliability.

[0097] The centrally located fixed frame single column 11 not only supports the center of gravity of the car carrier plate 3 carrying the vehicle 4 reasonably and reliably, but also gives a very safe visual experience with its balanced and stable overall shape.

[0098] See Figure 14 , in order to avoid excavating the driving road surface during foundation construction, the bottom end of the fixed frame single column 11 can be rigidly connected to the front end of the fixed frame single column ground beam 111 extending backward, and the fixed frame single column ground beam 111 is reliably connected to the concrete foundation in the foundation pit, and then covered with floor tiles or green land soil.

[0099] The present invention can be arranged side by side as shown in Figure 15 , and the single upright column 11 of the fixing frame is arranged outside the curb 52 on the roadside to avoid occupying the traffic space inside the road. The bottom of the rear structure of the fixing frame 1 can be decorated into a continuous ceiling structure, acting as a covered corridor on the sidewalk, playing the role of shading and sheltering from the rain. For pedestrians on the sidewalk below, this group of side-by-side parking devices is as beautiful and practical as a normal pedestrian corridor.

[0100] In order to provide higher-quality services to vehicle owners, as shown in Figure 16 、 Figure 17 , the border structure of the forward movement frame 2 can be used to set up a forward movement frame hood 25 for the vehicle. Obviously, the structure of this hood 25 can be freely designed to achieve a more beautiful appearance.

[0101] Obviously, the single upright column 11 of the fixing frame referred to in the present invention can adopt a composite upright column structure formed by combining multiple columns as shown in Figure 18 .

[0102] In specific applications, as shown in Figure 19 , the two single upright columns 11 of the fixing frame are spanned across the front sides of two ground self-propelled parking spaces, so as to add a mechanical parking space above the two ground parking spaces.

[0103] In a scenario where the trafficable passage is very narrow, but there are open spaces or green spaces on both sides of the passage, as shown in Figure 20 and Figure 21 , the two devices can be arranged opposite to each other outside the road on both sides of the narrow passage, and the two devices share the road surface space for placing the car carrier to access the vehicle. In this way, two parking spaces can be created out of thin air. The trafficable ground passage in this scenario can be either a single-lane path similar to an outdoor community or an open space in a home courtyard that could originally park one vehicle. This scenario is quite common in some villa families. This application method can not only make full use of the space above the open space for parking, but also retain the original ground site for arranging various functional spaces such as flower and plant landscapes, fitness activities, and placing tea seats and reclining chairs.

[0104] Obviously, beside a narrow passage where only one-sided open space can be utilized, as shown in Figure 22 、 Figure 23 , the device can be arranged beside the passage, and parking spaces can also be created out of thin air. This occasion is quite common at the entrance of small residences.

[0105] In a small open space in front of a roadside building, as shown in Figure 24 、 25As shown, the space between the two fixed frame single columns 11 is used as a ground passage for vehicles and pedestrians to pass through, and a parking space is obtained above the open space. This situation is relatively common outside the garage entrance of a roadside villa with an indoor garage.

[0106] Obviously, between the forward-moving frame longitudinal guide beam 21 and the fixed frame longitudinal guide beam 12 of the present invention, an intermediate sliding rail beam with end pulleys can be provided to form a very common three-section telescopic arm structure. This structure also has the following features proposed by the present invention:

[0107] The fixed frame longitudinal guide beam 12 includes a fixed frame longitudinal guide beam lower rail surface 121 with a main guiding surface facing downwards and a fixed frame longitudinal guide beam upper rail surface 122 with a main guiding surface facing upwards;

[0108] At the front end of each fixed frame longitudinal guide beam 12, a fixed frame longitudinal guide beam front guide wheel 124 is provided;

[0109] The forward-moving frame longitudinal guide beam 21 includes a forward-moving frame longitudinal guide beam lower rail surface 211 with a main guiding surface facing downwards;

[0110] Driven by the forward-moving mechanism, the forward-moving frame 2 can reciprocate back and forth between the front limit position and the rear limit position,

[0111] During the reciprocating back-and-forth translation of the forward-moving frame 2, the rear guide wheel 212 of the forward-moving frame longitudinal guide beam is limited and guided by the fixed frame longitudinal guide beam lower rail surface 121 and the fixed frame longitudinal guide beam upper rail surface 122;

[0112] During the reciprocating back-and-forth translation of the forward-moving frame 2, the forward-moving frame longitudinal guide beam lower rail surface 211 is supported and guided by the fixed frame longitudinal guide beam front guide wheel 124.

[0113] Therefore, the use of a three-section telescopic arm in the prior art is also included within the scope of the defined technical features of the present invention.
