A lifting bridge parking device

Abstract

The patent of the present invention belongs to the field of motor vehicle parking equipment, and its name is a lifting bridge type parking equipment. In the existing parking equipment for motor vehicles, the car should be driven in directly to park, but it is difficult to solve the problem of the sloped inclined bridge, so it is designed to be a complex mechanical and electric power drive combination to complete the horizontal movement and vertical lifting and transportation of the car. However, this type of parking equipment is expensive and difficult to popularize. In order to overcome the above-mentioned shortcomings of the existing parking equipment, the present invention provides a lifting bridge type parking equipment, which has the advantage that the car can be driven directly to park. Its structure is mainly composed of a lifting bridge support frame 9 and a movable axle bridge plate 10. The left and right sides of the movable axle bridge plate 10 installed on the lifting bridge support frame 9 are respectively equipped with a set of hydraulic power devices for lifting and driving, so as to control the lifting and lowering of the sloped inclined bridge to realize the entry and exit parking of the car. This is a simple and popular parking equipment.

Description

Technical Field

[0001] The invention relates to a mechanical parking device. Background Art

[0002] 1. Based on Chinese patent number: ZL 2015 2 1106244.4; utility model patent name: retractable lifting movable bridge parking equipment. This patent discloses a motor vehicle parking equipment, the important technical features of which are reflected in the lifting bridge frame. The equipment is driven by hydraulic power and can realize the lifting of the sloped inclined bridge. The car can be driven up and down through the lifting movable axle bridge board and can also be parked on the bridge board; after the movable axle bridge board carries a car and rises to the horizontal position, another car can be driven under the movable axle bridge board for parking; it can also be combined to form a cluster parking equipment with multiple layers and multiple parking spaces. When each movable axle bridge board is raised to the horizontal position, one car can be parked, and another car can be parked under the movable axle bridge board.

[0003] 2. Features of the original background technology solution: Rigidly install bridge support rollers under the movable axle bridge

[0004] Background technology document ZL 2015 2 1106244.4 is a retractable lifting movable bridge parking device, whose lifting bridge frame 2 is equipped with a movable axle bridge plate 5, one end of the movable axle bridge plate 5 and one end of the upper part of the lifting bridge frame 2 are connected through a movable axle 4, and a bridge plate support roller 10 is rigidly installed in the middle of the lower part of the movable axle bridge plate 5, and the bridge plate support roller 10 has shaft ends extending on the left and right sides of the movable axle bridge plate 5, and the extended part is equipped with bearings. The extended left and right shaft ends of the bridge plate support roller 10 fall on the support surfaces of the left and right scissor-type lifting frames respectively, and the support surfaces of the left and right scissor-type lifting frames respectively lift the two extended shaft ends of the bridge plate support roller 10 to control the rise and fall of the movable axle bridge plate 5. The background technology scheme is characterized by the use of a single-row scissor frame. Due to the limitations of the single-row scissor frame structure, the single-row scissor frame can only be equipped with fixed feet at its left or right end, which reduces the safety and reliability of the scissor frame under stress.

[0005] 3. Disadvantages of the background technology solution:

[0006] 3.1 The live axle 4 is arranged at one end of the live axle bridge plate 5 of the background technology solution, and the live axle 4 is horizontally installed at one end of the upper part of the lifting bridge frame 2. The lifting and lowering of the live axle bridge plate 5 is the process of the live axle bridge plate rotating around the live axle 4. The bridge plate support roller 10 rigidly connected to the live axle bridge plate 5 also rolls along the upper support surface of the scissor-type lifting frame 6 along with the vertical lifting and lowering of the scissor-type lifting frame 6. Therefore, the position where the bridge plate support roller 10 is pressed by gravity is in a floating state, and is in a relative changing state with the load-bearing upper plane of the left and right scissor-type lifting frames 6. The reason is that due to structural limitations, there is no way to keep the supporting force of the left and right scissor-type lifting frames 6 at the vertical center line position of the left and right scissor-type lifting frames 6, which obviously reduces the safety and reliability of the equipment.

[0007] 3.2 In the comparative scheme, in order to maintain the straightening and guiding function of the scissor-type lifting frame 6, the scissor-type lifting frame 6 is equipped with a box-type structure. The disadvantage of the box-type structure is that the overall structure of the single-row scissor-type lifting frame becomes complicated.

[0008] 3.3 In the comparison scheme, a single-row scissor frame is used. Its disadvantage is that the fixed feet can only be arranged at the lower end of the end row pin axis at the left or right end of the single-row scissor frame. The limitation of this structure directly leads to the inability to locate the support point of the scissor frame at the vertical center position, which weakens the overall safety and reliability of the scissor frame.

[0009] 3.4 In the comparative scheme, a bridge support roller 10 is rigidly fixed under the middle of the live axle bridge 5, and the bridge support roller 10 extends out of the shaft ends with bearings on the left and right sides respectively, and rolls on the support surfaces of the left and right fork-type lifting frames 6 through the shaft end bearings to support the bridge board to carry the car. In such a combination, since the length of the left and right shaft ends on the scissor-type lifting frame 6 is very limited, it is easy for the live axle bridge 5 to fall off unexpectedly, which will cause the car carried on the live axle bridge 5 to lose its load, which is absolutely not allowed. Obviously, this scheme is a disadvantage caused by structural factors, and the disadvantages caused by structural factors are difficult to overcome. Summary of the invention

[0010] 1. Technical problems to be solved

[0011] 1.1 The present application solution simplifies the box-type structure of the scissor-type lifting frame (6) in the background technology solution while ensuring that the upright guiding function of the scissor-type lifting frame remains unchanged.

[0012] 1.2 The technical problem to be solved by this application is to avoid arranging fixed feet on the axis of the pins at the end of the scissor-type lift frame, and to position the fixed feet on the vertical center line of the scissor-type lift frame. The realization of this technical feature will enable the parking equipment to obtain significant overall safety and reliability.

[0013] 1.3 Since the length of the left and right shaft ends of the bridge plate supporting rollers (10) in the background technology solution that are placed on the left and right scissor-type lifting frames is very limited, it is easy for the active-axle bridge plate (5) to fall off, causing the car to lose its load, which is absolutely not allowed to happen. The present application solution aims to fundamentally solve this technical problem, so that the bearing capacity of the active-axle bridge plate supported by the scissor-type lifting frame is always maintained at the vertical center line position of the scissor-type lifting frame.

[0014] 1.4 In the background technical solution, when the scissors-type lifting frame and the lifting bridge are in relative motion and in working condition, the supporting force position of the supporting plane on the scissors-type lifting frame (6) relative to the bridge deck supporting roller (10) is in a floating and changing state. This state leads to a decrease in the overall safety and reliability of the parking equipment. The present application solution aims to solve this technical problem.

[0015] Technical Solution

[0016] 2 Technical features of this application plan

[0017] 1. This application is a lifting bridge parking device. Figure 5 , Figure 6 and Figure 7 The parking equipment is composed of a lifting bridge support frame (9), a movable bridge deck (10), a cross beam (11) and a double-row scissor frame (12); the base profile of the lifting bridge support frame (9) adopts a rectangular frame, and double-row scissor frames (12) are arranged on the left and right sides of the rectangular frame respectively, ensuring that an escape space for parking cars is reserved in the middle of the double-row scissor frame (12), and the double-row scissor frame (12) adopts a three-layer arm rod through-pin structure with two arms clamping one arm; a solution is adopted to install a cross beam (11) on the left and right double-row scissor frames (12), and this cross beam (11) is a round shaft The cross beam (11) has two ends which are respectively installed on the left and right double row scissor frames (12) through fixed seat bearings (14), and the cross beam (11) and the fixed seat bearings (14) cooperate to be rotatable; a live axle bridge plate (10) is pressed on the top of the cross beam (11), and a live axle (16) is arranged at one end of the live axle bridge plate (10), and the live axle (16) is horizontally mounted on one end of the upper part of the lifting bridge support frame (9); the cross beam (11) can be rotated with the live axle (16) as the center and the length of the bridge plate as the radius; the middle of the live axle bridge plate (10) falls on the cross beam (11), and the cross beam (11) As the left and right double-row scissor frames (12) are raised or lowered, they are closely attached to the live-axle bridge plate (10) for friction rolling to support the live-axle bridge plate (10); the driving force equipped with the left and right double-row scissor frames (12) can make the left and right double-row scissor frames (12) rise or fall synchronously; the synchronous action of the left and right double-row scissor frames (12) adopts the scheme of equipped with sprocket chains or steel cable pulleys, or directly uses a hydraulic system for synchronous drive; the arrangement of the cross beam (11) and the fixed feet (7) of the double-row scissor frames is selected, and the pin axis of the middle row of the double-row scissor frames (12) or the adjacent double-row pin axis is selected. A transverse beam (11) is arranged at the upper end of the longitudinal pin axis of the middle bisector of the scissor-type frame and a fixed foot (7) is arranged at the lower end; a linear track or a wheel-rail matching method is adopted between the movable foot (4) of the double-row scissor-type frame (12) and the track; a limit gear (8) is arranged at the end of the track; a lifting bridge support frame combination mechanism equipped with a complete lifting bridge function can be used as a parking basic unit, and any number of parking basic units and any number of rectangular parking frames equipped with top panels are used to be fixedly connected accordingly, and any combination in the three-dimensional directions of length, width and height can form any number of combined parking spaces.

[0018] 2. According to the lifting bridge type parking equipment described in the present application, a lifting bridge support frame equipped with a complete lifting bridge function can be used as a basic parking unit. By using such basic parking units in the three-dimensional directions of length, width and height and a rectangular parking frame equipped with a top panel, any number of combinations can be made to form two-story, three-story, and up to ten-story combined parking spaces.

[0019] 2.1 To overcome the shortcomings of the background technology, a new technology solution must be developed. The single-row scissor frame solution in the reference document can no longer be used. For this reason, the present application introduces a double-row scissor frame. For details about the single-row scissor frame and the double-row scissor frame, please see the following description.

[0020] 2.2 The structure of equipping the bridge support roller under the movable axle bridge plate in the background technology solution is no longer followed, and the bridge support roller is cancelled. Figure 5 , Figure 6 and Figure 7 , adopt the scheme of installing a cross beam (11) on the left and right double-row scissor frame (12), and the cross beam is cylindrical; the two ends of the cross beam (11) are respectively positioned and installed on the left and right double-row scissor frame (12) through the fixed seat bearing (14), and the cross beam (11) and the fixed seat bearing (14) cooperate to rotate. The movable axle bridge plate (10) falls on the cross beam (11), and the cross beam (11) accompanies the rise or fall of the left and right double-row scissor frame (12) and at the same time, frictionally rolls with the movable axle bridge plate (10) to support the movable axle bridge plate (10). The arrangement of this cross beam (11) is equivalent to arranging a load-bearing bumper under the movable axle bridge plate (10). The movable axle bridge plate (10) above is carried in the manner of this cross beam (11), and the movable axle bridge plate (10) carrying the car does not have the condition to fall under the cross beam (11) in terms of structure, so that the parking equipment as a whole has significant safety and reliability. Obviously, the scheme structure of the present application and that in the comparative document (background scheme) are not exactly the same. Compared with the scheme in the comparative document, the innovative design of the present application has outstanding technical progress.

[0021] 2.3 See this application plan Figure 5 and Figure 6First, the fixed foot (7) of the scissor frame is arranged at the lower end of the middle column pin axis of the double-row scissor frame (12), and then the cross frame beam (11) is directly installed across the fixed seat bearing (14) at the upper end of the middle column pin axis of the left and right double-row scissor frames (12), so that the left and right double-row scissor frames (12) and the cross frame beam (11) are assembled into one body. This structure determines that the pressure applied by the active axis bridge plate (10) to the cross frame beam (11) always acts on the position of the middle column pin axis of the left and right double-row scissor frames (12). When the movable axle bridge plate (10) and the cross beam (11) move relative to each other, the cross beam (11) moves up and down along the middle axis of the pins of the left and right double-row scissor frames (12) as the left and right scissor frames are raised and lowered, and does not move left and right; the movable axle bridge plate (10) is lifted and lowered by the cross beam (11), and the arrangement structure is very reasonable. What is important is that the two ends of the cross beam (11) are always pressed on the middle axis of the pins of the left and right double-row scissor frames (12), and the lower end of the middle axis is the fixed foot (7) of the double-row scissor frames. The fixed foot (7) is fixed on the linear track (5) so that the fixed foot (7) of the double-row scissor frames always vertically supports the cross beam during operation. This structure achieves the ideal state of making the double-row scissor frames (12) bear gravity at a fixed position on the vertical center line. Compared with the technical solution in the background document, the safety hazards of the original background solution are fundamentally eliminated, and the overall safety and reliability of the parking equipment application solution are substantially improved, which has outstanding technical progress.

[0022] 2.4 Simplify the scheme by eliminating the box-type structure. The scheme in the comparative document (that is, the background scheme) uses a single-row scissor frame and needs to be installed in a box-type structure to ensure that it has the function of straightening and retracting. The box-type structure can be simplified in the present application scheme because a double-row scissor frame is adopted; the arm structure of the double-row scissor frame also adopts a three-layer arm pin-through structure with two arms clamping one arm. This structure itself has the function of straightening and retracting under gravity, and there is no weak line in the pin shaft joint. It has the characteristics of being strong and resistant to collapse as a whole. Therefore, there is no need to configure a box-type structure, which achieves functional equivalence and structural simplification, and has outstanding technical progress.

[0023] 2.5 This application plan, Figure 5 The double row scissor frame is used Figure 3 The double row scissor frame example installation is studied. Figure 3 The double-row scissor frame in the middle is symmetrical about the middle row pin axis, and the fixed foot (fixed on the track) is arranged at the lower end of the middle row pin axis and the cross beam is arranged at the upper end. There are other double-row scissor frames that are not symmetrical about the middle row pin axis, such as Figure 2 and Figure 4The double-row scissor frame in the figure has no middle row pin axis to choose from, but the longitudinal row pin axis of this double-row scissor frame adjacent to the middle bisector can be selected, and then the fixed foot is arranged at the lower end and the cross beam is arranged at the upper end, so that the safety and reliability of the cross beam support force is still very good. In short, it is possible to avoid selecting fixed feet on the left end pin axis or the right end pin axis, which is the outstanding technical advantage of the double-row scissor frame. Therefore, the application scheme selects the double-row scissor frame to replace the single-row scissor frame, which has outstanding technical progress. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] 1. In order to facilitate the analysis of the problem, the following relevant phrases are defined and explained in this application plan:

[0034] 1.1 The longitudinal pin on the left end of the scissor frame is the left end pin;

[0035] 1.2 The longitudinal pin on the right end of the scissor frame is the right end pin;

[0036] 1.3 The longitudinal pin in the middle of the left and right longitudinal pins of the scissor frame is called the middle pin;

[0037] 1.4 A scissor frame with only three rows of pins in the longitudinal direction is called a single-row scissor frame (see Figure 1 );

[0038] 1.5 Scissor stands with 4 or more rows of pins in the longitudinal direction are collectively referred to as double-row scissor stands (e.g. Figure 2 , Figure 3 , Figure 4 );

[0039] 1.6 The left and right end pins of the scissor arms of the single-row scissor frame are weak points when supporting gravity. Figure 1 There is no connecting arm in rows a and b, and in rows c and d, so the bearing strength is very weak. This is an inherent disadvantage of the single-row scissor frame structure.

[0040] 1.7 This application adopts a three-layer scissor arm structure with two arms clamping one arm and a cross-pin shaft. Under this premise, the distinction between the connecting arm and the non-connecting arm is explained.

[0041] Connecting arm: If the end of the scissor arm is not located at the pin shaft position of the scissor arm, the arm at the pin shaft position is called a connecting arm. Experiments have shown that the connecting arm pin position has the function of straightening and extending when subjected to gravity, and has the characteristics of being strong and resistant to collapse.

[0042] Non-connected arm: If the end of the scissor arm appears at the pin position of the scissor arm, the arm at this pin position is called a non-connected arm. Experiments have shown that when subjected to gravity, the pin position of the non-connected arm does not have a reliable straightening and telescoping function, and has a potential risk of collapse.

[0043] 1.8 About the length of the scissor arms

[0044] There are many different structural forms of the double-row scissor stand. The scissor arms of the double-row scissor stand with different structural forms have at least two lengths, such as Figure 5 It can be seen that there are two types of scissor arms: a short scissor arm (1) and a long scissor arm (2).

[0045] 2. Analysis on the arm conditions and load-bearing characteristics of single-row scissor frame

[0046] 2.1 Figure 1 This is a single-row scissor stand. Its top and bottom rows of pins need not be discussed here. In addition, there are 5 rows of pins, with 2 pins in rows ab and cd, and only one pin in the other 3 rows.

[0047] 2.2 The three rows with only one pin shaft, although they all have only one pin shaft through pin, are all connected arm rods, and have the characteristics of vertical load bearing, firmness and resistance to collapse when subjected to gravity;

[0048] 2.3 In rows ab and cd, although there are two pins, since they are non-connecting arm rods, experiments have shown that there is a potential risk of collapse when subjected to gravity.

[0049] 2.4 From the above analysis, it can be seen that the single-row scissor stand has an unsafe hazard of easy collapse when in use. Two of the five rows of pin shafts do not have connecting arm rods. The rows without connecting arm rods are weak rows and are easy to collapse. This is the main factor that makes the single-row scissor stand easy to collapse.

[0050] 3. Analysis on arm conditions and load-bearing characteristics of double-row scissor frame

[0051] 3.1 Figure 3 Take it as an example, it is a double-row scissors frame. Its top and bottom rows of pins are not discussed here. In addition, there are 5 rows of pins. There are 3 pins in the eif row and gjh row. Although points e, f and g, h are non-connected arm rods, since points i and j are connected arm rods and exist in the eif row and gjh row respectively, these 2 rows are guaranteed to have the characteristics of vertical load-bearing, firm and anti-collapse when subjected to gravity.

[0052] 3.2 The other three rows each have two pins, all of which are connected arm rods, and have the characteristics of vertical load-bearing, firm and anti-collapse when subjected to gravity;

[0053] 3.3 Conclusion: Figure 3 The above five rows of pins of the double-row scissor frame all have connecting arms. Experiments have proved that when the double-row scissor frame is in use, it can withstand gravity and has the function of straightening and stretching. There is no weak row in the pin joint, and the whole has the characteristics of being strong and resistant to collapse. Figure 2 and Figure 4 They are also double-row scissor frames. Similarly, without considering their top and bottom rows of pin shafts, each other row of pin shafts has a connecting arm rod, and the whole is strong and resistant to collapse.

[0054] 4. Analysis of the use of single-row scissor stands and double-row scissor stands

[0055] 4.1 Figure 1 It is a single-row scissor frame. The left and right end pins of the scissor arm of the single-row scissor frame are weak points when supporting gravity, such as Figure 1 There is no connecting arm between points a and b, and between points c and e, so the load-bearing capacity is very weak. This is an inherent structural defect of the single-row scissor frame when it is in use.

[0056] 4.2 Due to the structural shortcomings of the single-row scissor frame, it does not have the good conditions for arranging positioning supports required in this application scheme.

[0057] Imagine that if the cross beam is directly positioned on the upper end of the left end column pin axis of the single-row scissor frame, and a fixed foot is arranged at the bottom end of the left end column pin axis, in this way, the left end column pin axis will only move up and down in a straight line; the right end column pin axis will not only move up and down in a straight line, but also maintain a parallel state with the left end column pin axis while moving left and right. However, this structure puts the cross beam in a bad supporting position. The cross beam is on the left end column pin axis of the single-row scissor frame, which is a longitudinal edge support. Experiments have shown that this structure is unreliable and has extremely poor safety when the cross beam needs to bear a large weight. Therefore, the single-row scissor frame has its own structural shortcomings, and it does not have good conditions for arranging positioning supports.

[0058] 4.3 The following reliability analysis is carried out using the double-row scissor frame as an example

[0059] Figure 3 The structure of the double-row scissor frame itself has the conditions to fix the cross beam on the axis of the middle column pin. The technical characteristics of the positioning support: the cross beam is positioned at the upper end of the axis of the middle column pin of the double-row scissor frame, and the fixed foot is positioned on the track at the lower end of the axis of the middle column pin. When the double-row scissor frame is lifted or lowered, the pins on the axis of the middle column pin will only move up and down in a straight line and will not move left and right; the pins on the left and right columns will also move up and down in a straight line and move left and right with the axis of the middle column pin as the reference line while maintaining a parallel state with the axis of the middle column pin during movement. This structure enables the cross beam on the axis of the middle column pin to obtain an ideal support state, and the cross beam has a fixed foot support at the lower end of the axis of the middle column pin. The structure is safe and reliable. The most important point is that the cross beam and the fixed foot are always on the same vertical line and remain unchanged.

[0060] 4.4 Due to the different number of longitudinal pin axis lines, the double-row scissor frame has a variety of structural forms. However, as long as it is a double-row scissor frame, it has the conditions to avoid selecting the limit fixed foot under the left or right end row pin axis line. Although some double-row scissor frames do not have a middle row pin axis line, at least a longitudinal row pin axis line adjacent to the center line of the scissor frame can be selected to arrange the cross beam and fixed foot. In short, it is possible to avoid the left or right end row pin axis line to arrange the cross beam and fixed foot. Therefore, the arrangement of the cross beam and fixed foot of the double-row scissor frame is a prominent technical improvement in the load-bearing reliability compared with the single-row scissor frame.

[0061] 5. Eliminate the box-type structure. In the comparative technical solution, the single-row scissor frame must be equipped with a box-type structure when in use in order to maintain reliable upright guiding characteristics, which is an inherent structural defect of the single-row scissor frame. Figure 3 It is a double-row scissor frame, which can be used without a box-type structure and still has the characteristics of upright guidance. Through comparison, it can be seen that in the scheme of lifting bridge parking equipment, the technical characteristics of the double-row scissor frame are significantly better than those of the single-row scissor frame, and it has outstanding technical progress.

[0062] 6. The beneficial effects of using a double-row scissor frame

[0063] 6.1 According to the comparative document scheme "Retractable lifting bridge parking equipment", it is known that it uses a single-row scissor frame. Through analysis, it can be seen that the disadvantage of the single-row scissor frame is that the fixed foot can only be arranged on the left or right end column pin axis, which is a longitudinal edge support. If the cross frame beam and the fixed foot are installed on the same vertical line, this edge support structure is unreliable when a large weight is applied to the cross frame beam, and the safety is very poor. On the contrary, the double-row scissor frame overcomes this disadvantage and has the condition of selecting the fixed foot at the lower end of the middle column pin axis. After the fixed foot is positioned at the lower end of the middle column pin axis, the middle column pin axis of the double-row scissor frame does not move left and right when it is lifted or lowered, and the scissor arms on the left and right sides of the middle column pin axis are closed or opened based on the middle column pin axis. Under this condition, the cross frame beam is arranged at the upper end of the middle column pin axis, and the bearing capacity of the cross frame beam is just pressed on the fixed foot at the lower end of the middle column pin axis, realizing an ideal center-positioned load-bearing structure with a stable, safe and reliable center of gravity. In short, the double-row scissor frame completely overcomes the shortcomings of the single-row scissor frame, arranges the cross beam and the fixed feet on the axis of the middle row pin, brings significant safety and reliability, and has outstanding technical progress.

[0064] 6.2 Figure 3 The double-row scissor frame is symmetrical about the middle row pin axis. You can choose to arrange the cross beam at the upper end of the middle row pin axis and the fixed foot at the lower end; for example Figure 2 and Figure 4 In the case of the double-row scissor stands and other ones that are not symmetrical about the center column pin axis, there is no center column pin axis to choose from, but the cross beam can be arranged at the upper end of the longitudinal column pin axis adjacent to the middle bisector and the fixed foot can be arranged at the lower end, which can also achieve the load-bearing gravity of the adjacent middle stable position. In short, it can avoid the selection of fixed feet on the left or right end column pin axis. This is the structural advantage of all double-row scissor stands, which is not available in single-row scissor stands. Compared with the single-row scissor stands in the comparative document, the use of double-row scissor stands brings significant technical progress to the overall safety and reliability of parking equipment.

[0065] 7. Lifting bridge type multi-storey multi-parking parking equipment

[0066] In order to explain the multi-story multi-parking space parking system clearly, only a three-story multi-parking space parking system is used as an example for description. Figure 8It is a lateral structure of a three-story multi-parking parking system with a lifting bridge. It shows the combination of multiple parking spaces in the horizontal and height directions. We call it a "facade", with a total of 28 parking spaces. Let n be a positive real number, and the number of parking spaces is 28n if n facades of the same form with 28 parking spaces are installed side by side. Of course, it can also be changed in the three-dimensional directions of length, width and height as needed, and can be combined into any number of multi-story and multi-facade parking spaces.

[0067] This lifting bridge parking equipment has the advantage that cars can be driven directly onto it and parked. The important technical features are reflected in the lifting bridge frame. The equipment uses hydraulic power to drive the bridge plate to lift and lower, which can realize the lifting and lowering of the slope bridge and the horizontal bridge. Cars can be driven up and down through the lifting bridge and can also be parked on the bridge; when the movable bridge plate carries a car and rises to the level, another car can be driven under the bridge plate for parking; each individual lifting bridge parking equipment works independently as a basic unit, and any number of lifting bridge parking equipment basic units and any number of rectangular parking frames with upper covers can be combined into any number of parking spaces in the three-dimensional directions of length, width and height. When the inclined bridge plate on each lifting bridge frame rises to the horizontal position, one car can be parked, and another car can be parked under each bridge plate; the car can also drive along multiple inclined bridges to the top of the combined parking equipment, or from the top to the ground. The biggest feature is that it is suitable for parking in the environment around old buildings in Chinese urban blocks, because it can be installed only on flat ground and does not require any additional construction. It is different from all kinds of parking equipment now and has outstanding popularization and promotion value.

[0068] 8. Lifting bridge parking equipment can effectively alleviate the pressure of urban parking congestion

[0069] For the purpose of popularization and promotion, the driving of the lifting movable bridge parking equipment in this scheme is a new scheme that does not require cable power supply. This parking equipment can be operated independently as a basic parking unit, and can be combined as needed to form any number of parking spaces with any number of layers and facades.

[0070] It can be directly arranged on the ground for use without destroying the flatness of the original ground, and the equipment can be flexibly placed or moved; the structure of this new parking equipment can also be combined with more "facades" and more layers of parking spaces as needed, which can effectively increase the utilization rate of parking space. It is not only low-cost, but most importantly, it is easy to popularize and promote, which can effectively alleviate the problem of parking congestion in the real society and produce unexpected social benefits; another advantage of the solution of the present invention is that all parking spaces can be filled, which is an advantage not possessed by existing intelligent parking equipment.
