The left and right shaft ends extending out of the bridge plate supporting roller 10 respectively fall on the supporting surfaces of the left and right scissor-type lifting frames, and the two extending shaft ends of the bridge plate supporting roller 10 are respectively lifted by the supporting surfaces of the left and right scissor-type lifting frames to control the movable shaft bridge plate 5 to ascend and descend. The technical scheme of the background is characterized in that a single-row fork shearing frame is adopted, and due to the limitation of the structure of the single-row fork shearing frame, the single-row fork shearing frame can only arrange fixing pins at the left end or the right end of the single-row fork shearing frame, so that the stress safety and reliability of the fork shearing frame are reduced.
3. The disadvantages of the background art solutions:
3.1 live axle bridge plate 5 one end of background technical scheme is provided with live axle 4, and live axle 4 is installed in the upper portion one end of lift bridge frame 2 of horizontal type. The lifting of the movable shaft bridge plate 5 is the process that the movable shaft bridge plate rotates around the movable shaft 4. The bridge plate supporting roller 10 rigidly connected with the live axle bridge plate 5 needs to roll along the upper supporting surface of the scissor type lifting frame 6 along with the vertical lifting of the scissor type lifting frame 6, so the gravity pressure applying position of the bridge plate supporting roller 10 is in a moving state, and is in a relative change state with the upper bearing plane of the left scissor type lifting frame 6 and the right scissor type lifting frame 6, the reason is that the structure is limited, the supporting force of the left scissor type lifting frame 6 and the right scissor type lifting frame 6 is kept at the vertical center line position of the left scissor type lifting frame 6 and the right scissor type lifting frame 6, and the safety and reliability of the equipment are obviously reduced.

3.4 in the comparison scheme, a bridge plate supporting roller 10 is rigidly fixed below the middle part of the live axle bridge plate 5, the left and right sides of the bridge plate supporting roller 10 are respectively extended out of the axle ends sleeved with bearings, and the axle ends roll on the supporting surfaces of the left and right fork type lifting frames 6 through the axle end bearings so as to support the bridge plate to bear the automobile. So cooperate, because the length that the axle head was taken on cutting fork formula crane 6 about is very limited, the unexpected condition that loose axle bridge plate 5 drops appears easily, can lead to the car that bears on the loose axle bridge plate 5 to take place to lose the year accident from this, and this is absolutely not allowed. Obviously, this solution is a drawback due to the constructional elements, which are difficult to overcome.

2.5 scheme of the application, the multiple fork-shearing frame in fig. 5 is studied by using the example installation of the multiple fork-shearing frame in fig. 3, the multiple fork-shearing frame in fig. 3 is symmetrical about the axis of the center pin, and the arrangement of a fixed foot (fixed on a rail) at the lower end of the axis of the center pin and a cross beam at the upper end is selected. There are other multiple fork-shearing frames which are not symmetrical about the central axis, such as fig. 2 and 4, in which the multiple fork-shearing frame has no central axis for selection, but it is possible to select such multiple fork-shearing frame adjacent to the central axis of the central uniform line, and then to arrange the fixing legs at the lower end and the cross beam at the upper end, so that the safety and reliability of the supporting force of the cross beam are still good. In a word, the technical advantage that a fixed foot is selected on the left end pin axis or the right end pin axis can be avoided, and the multiple-row fork shearing frame protrudes, so that the technical progress of the protrusion of the multiple-row fork shearing frame instead of a single-row fork shearing frame is achieved.

Detailed Description
1. To facilitate the analysis of the problem, the following related phrases are defined and explained in the present application
1.1, a longitudinal pin shaft at the left end of the fork shearing frame is a left end row pin shaft;
1.2 the longitudinal pin shaft at the right end of the fork frame is a right end row pin shaft;
1.3 the longitudinal pin shaft in the middle of the range of the longitudinal pin shaft at the left end row and the longitudinal pin shaft at the right end row of the fork frame is called a middle row pin shaft;
1.4 the fork shearing frame with only 3 rows of pins in the longitudinal direction is called a single-row fork shearing frame (see figure 1);
1.5 fork shearing frames with 4 rows and more than 4 rows of pin shafts in the longitudinal direction are collectively called a tandem fork shearing frame (for example, fig. 2, 3 and 4);
1.6 the left end column pin shaft and the right end column pin shaft of the scissor arm of the single-row scissor rack are weak points when supporting gravity, as shown in figure 1, no communication arm rod is arranged in the rows a and b and in the rows c and d, so the bearing strength is weak. This is an inherent disadvantage of the single row scissor fork arrangement.
1.7 this application scheme adopts two arms to press from both sides the three-layer of fork armed lever alternately to wear the round pin axle construction, does the discernment explanation of leading to armed lever and non-leading to armed lever under this prerequisite
The connecting arm rod: if the position of the pin shaft penetrating through the scissor arm rod does not have the end part of the scissor arm rod, the arm rod at the pin shaft part is called a communication arm rod; experiments prove that the pin penetrating position of the universal joint arm rod has the functions of straightening and stretching when bearing gravity and has the characteristics of rigidity and bending and collapse resistance.
Non-through linkage arm: if the end part of the scissor arm rod appears at the position of the pin shaft of the scissor arm rod, the arm rod at the pin shaft part is called a non-communication arm rod. Experiments prove that the pin penetrating position of the non-communication arm rod does not have reliable straightening and stretching functions when bearing gravity, and has potential hidden trouble of easy collapse.
1.8 Length dimension of scissor arms
There are many different forms of compound scissor fork, and the arms of compound scissor forks of different forms have not less than 2 length dimensions, for example, two of which can be seen in fig. 5: a short scissor arm (1) and a long scissor arm (2).
2. Analysis on conditions and bearing characteristics of single-row fork-shearing arm lever
2.1 is discussed by way of example in fig. 1. The fork is a single-row fork, the pin shafts in the top row and the bottom row of the fork are not discussed, and the pin shafts in the 5 rows are also provided, 2 pin shafts are respectively arranged in the ab row and the cd row, and only one pin shaft is arranged in the other 3 rows.
2.2 the 3 rows only have one pin shaft, although all have the pin penetrating of one pin shaft, all are the connecting arm rods, and have the characteristics of vertical bearing, firmness and collapse resistance when bearing the gravity;
23 in ab row and cd row, though all have the round pin of wearing of 2 round pins axle, because all be the UNICOM's armed lever, prove through the experiment: the potential hidden trouble of easy breaking down exists when bearing the gravity.
2.4 according to the analysis, the single-row scissor rack has the potential safety hazard of being easy to fold and collapse when in use, 2 rows of the 5-row pin shafts have no communication arm rod, and the non-communication arm rod is a weak row and is easy to fold and collapse, which is a main factor of the single-row scissor rack being easy to fold and collapse.
3. Arm lever condition and bearing characteristic analysis of compound type fork shearing frame
3.1 discuss by way of example in fig. 3, it is a multiple row fork-cutting frame, its top row and bottom row of pin shafts are not discussed here, in addition, there are 5 rows of pin shafts; and 3 pin shafts are respectively arranged on eif row and gjh row, although e point, f point, g point and h point belong to non-communication arm levers, since i point and j point are communication arm levers and are respectively arranged on eif row and gjh row, the 2 rows are guaranteed to have the characteristics of vertical bearing, stiffness and collapse resistance when bearing gravity.
3.2 the other 3 rows are respectively provided with penetrating pins of 2 pin shafts, which are all communicated arm rods, and have the characteristics of vertical bearing, firmness and collapse resistance when bearing gravity;
3.3 summarizing, in fig. 3, the through link lever exists in the above 5 rows of pin shafts of the compound fork carriage, and experiments prove that: when the compound type shearing fork frame is used, the compound type shearing fork frame has the functions of bearing gravity, straightening and stretching, the pin shaft joint has no weak line, and the whole compound type shearing fork frame has the characteristics of firmness and bending collapse resistance. Due to the fact that the scissor fork frames are arranged in the same row as shown in the figures 2 and 4, on the premise that the pin shafts of the top row and the bottom row are not considered, the pin shafts of each other row are provided with the connecting link arm rod, and the scissor fork frames have the characteristics of rigidity and collapse resistance on the whole.
4. Single row fork and multiple row fork for analysis of use
4.1 fig. 1 is a single-row fork-shearing frame, and the pin shaft at the left end and the pin shaft at the right end of the fork arm of the single-row fork-shearing frame are weak points when supporting gravity, for example, in fig. 1, no connecting arm rod exists between the points a and b and between the points c and e, so the bearing force is weak, which is the inherent defect of the structure of the single-row fork-shearing frame in use.
4.2 due to the structural disadvantages of the fork carriage itself, it does not have the good conditions for arranging the positioning support as claimed in the solution of the present application
Trying to find that if the cross frame beam is directly positioned at the upper end of the axis of the pins at the left end of the single-row fork shearing frame, the bottom end of the axis of the pins at the left end is provided with a fixed foot, so that the pin shaft at the left end can only do vertical linear telescopic movement when positioned; the right end row pin shaft can do up-and-down linear telescopic movement and move left and right while keeping the parallel state with the left end row pin shaft. However, the structure enables the cross beam to be in a poor supporting force position, the cross beam is positioned on a left end row pin axis of the single-row fork shearing frame and is supported at the longitudinal edge, and experiments prove that the structure is unreliable and extremely poor in safety when the cross beam needs heavy weight for bearing. Therefore, the single-row scissor fork has the structural disadvantage of not having good conditions for arranging the positioning support.
4.3 reliability analysis using multiple fork-shearing frames as an example
The compound fork frame in fig. 3 has the structure which has the condition of fixing the cross beam on the axis of the center pin, and the technical characteristics of the positioning support: the cross beam is positioned at the upper end of the axis of the middle row pin of the compound fork shearing frame, and the fixed foot is positioned at the lower end of the axis of the middle row pin and positioned on the track. When the compound fork shearing frame does lifting movement, the pin shaft on the axis of the middle pin only can do up-and-down linear telescopic movement and can not move left and right; the left end row pin shaft and the right end row pin shaft can also do vertical linear telescopic movement, and the middle row pin shaft is taken as a datum line, moves left and right and keeps parallel to the middle row pin shaft in movement. The structure enables the cross frame beam on the axis of the middle pin to obtain an ideal supporting force state, and the cross frame beam is correspondingly supported by the fixing feet at the lower end of the axis of the middle pin, so that the structure is safe and reliable, and the most important point is that the cross frame beam and the fixing feet are always unchanged on the same vertical line.
4.4 due to the difference of the number of the pin axes, the compound fork shearing frame has various structural forms, however, as long as the compound fork shearing frame has the condition of avoiding selecting the limiting fixed foot under the pin axes at the left end or the right end, although the compound fork shearing frame has no pin axis at the middle end, at least a certain pin axis adjacent to the center line of the fork shearing frame can be selected to arrange the cross frame beam and the fixed foot, in short, the cross frame beam and the fixed foot are arranged by avoiding the pin axes at the left end or the right end, therefore, the technical progress of arranging the cross frame beam and the fixed foot on the compound fork shearing frame in the bearing reliability is more outstanding than that of arranging the single fork shearing frame.
5. The box structure is eliminated. In the comparison technical scheme, the single-row scissor frame is required to be provided with a box-type structure when in use, so that the reliable straightening and guiding characteristics can be kept, which is a defect of the single-row scissor frame in the congenital structure. Fig. 3 is a double row type fork-shearing frame, which can be used without a box-type structure and still has the characteristics of straightening and guiding, and as can be seen by comparison, in the scheme of the lifting bridge type parking equipment, the technical characteristics of the double row type fork-shearing frame are obviously superior to those of a single row type fork-shearing frame, and the technical progress is outstanding.
6. Beneficial effect of adopting compound fork frame
6.1 see the reference scheme "retractable overhead parking equipment", which uses a single-row scissor carriage. The disadvantage of the single-row fork-shearing frame is that the fixing feet can only be arranged on the pin axis of the left end row or the right end row, and are longitudinal edge supports, if the cross frame beam and the fixing feet are assembled on the same vertical line, the edge support structure is unreliable and has poor safety when heavy weight is applied on the cross frame beam. On the contrary, the double-row type fork shearing frame overcomes the defect and has the condition that the fixing feet are selected at the lower end of the axis of the middle row pin, when the fixing feet are positioned at the lower end of the axis of the middle row pin, the double-row type fork shearing frame does not move left and right of the axis of the middle row pin during lifting, the fork shearing arms at the left side and the right side of the axis of the middle row pin are folded or unfolded by taking the axis of the middle row pin as a reference, under the condition, the cross frame beam is arranged at the upper end of the axis of the middle row pin, the bearing capacity of the cross frame beam is just pressed on the fixing feet at the lower end of the axis of the middle row pin, the ideal center positioning bearing structure is. In a word, the compound fork shearing frame completely overcomes the defects of a single-row fork shearing frame, and the transverse frame beam and the fixing feet are arranged on the middle row pin axis, so that the obvious safe and reliable animal is brought, and the technology has outstanding progress.
6.2 the compound fork shearing frame in fig. 3 is symmetrical about the axis of the middle pin, and a cross frame beam is arranged at the upper end of the axis of the middle pin and a fixing foot is arranged at the lower end of the axis of the middle pin; there are also compound fork arms such as those of fig. 2 and 4 and others that are not symmetrical about the king pin axis, without the king pin axis being available for selection, but with the option of placing crossbeams at the upper ends and fixing feet at the lower ends of the king pin axes adjacent to the mean line, the loading of gravity adjacent to the mean line can also be achieved. In a word, the fixing feet can be prevented from being selected on the pin axes of the left end row or the right end row, which is the structural advantage of all the multiple-row fork shearing frames and is not possessed by the single-row fork shearing frame. Compared with the single-row fork shearing frame in the scheme of the comparison document, the adoption of the multiple-row fork shearing frame brings remarkable technical progress for the overall safety and reliability of the parking equipment.
7. Lifting movable bridge type multilayer multi-parking-place parking equipment
For clarity of illustration, only three-level multi-space parking facilities are described as an example, fig. 8 is a side structure of a lifting movable bridge type three-level multi-space parking facility, showing a combination of multiple spaces in horizontal and height directions, which we call as 1 "facade", for a total of 28 spaces. Let n be positive real number, n vertical faces with 28 parking spaces in the same form are installed and combined in parallel, the parking number is 28n, and the parking space number can be changed in the three-dimensional directions of length, width and height according to requirements and can be combined into any multi-layer multi-vertical-face parking space
The lifting movable bridge type parking equipment has the advantage that the automobile can be directly driven to park. The device is characterized in that the device is embodied in a lifting bridge frame, the device drives an axle plate to lift by adopting hydraulic power, the lifting change of a gradient bridge and a horizontal bridge can be realized, and an automobile can be driven to move up and down by opening the lifting bridge and can also be parked on the bridge; when the movable bridge plate bears one automobile and rises to the horizontal state, the other automobile can be driven into the lower part of the bridge plate for parking; each independent lifting bridge type parking device is used as a basic unit and works independently, any number of lifting bridge type parking device basic units and any number of rectangular parking frames with upper cover plates can be combined into any number of parking spaces in the three-dimensional directions of length, width and height, an inclined bridge plate on each lifting bridge frame can stop one automobile when being lifted to the horizontal position, and the other automobile can be stopped below each bridge plate; the vehicle can also be driven along several ramp bridges up to the top of the combined parking installation or from the top up to the ground. The parking device is mainly characterized by being suitable for parking around old buildings in the city block of China, can be assembled only on flat ground without any additional construction, is different from all types of parking devices at present, and has outstanding popularization and promotion values.
8. Pressure of lifting movable bridge type parking equipment capable of effectively relieving urban parking congestion
In consideration of popularization and promotion, the driving of the lifting movable bridge type parking equipment is a new scheme without a cable power supply, the parking equipment can be independently operated to work as a parking basic unit, can be combined according to needs, and can be combined into any number of layers and multiple vertical surfaces to form any number of parking spaces.
The device can be directly arranged on the ground plane for use, the original flat state of the ground is not damaged, and the device can be flexibly placed or transferred; the structure of the parking equipment with the new scheme can also be used for combining more 'facades' and more layers of parking spaces according to needs, can effectively increase the utilization rate of parking space, has low cost, is easy to popularize and popularize above all, can effectively relieve the problem of congestion of parking in the real society, and can generate unexpected social benefits; the scheme of the invention has the advantage that all parking spaces can be fully parked, which is an advantage that the existing intelligent parking equipment does not have.
