Description

Technical Field

[0001] The invention belongs to a mechanical parking device, in particular to a small parking device used for lifting and moving a vehicle forward and backward. Background Art

[0002] In the patent applications with application numbers 202311862954.9 and 202410165908.1, a roadside overhead parking technology solution with a vehicle-carrying plate that can be moved forward and raised and lowered is introduced. The solution comprises a fixed frame and a forward-moving frame. The forward-moving frame is arranged between the left and right side beams of the fixed frame and can be suspended and moved forward in the direction of the roadway. A vehicle-carrying plate suspended by a lifting rope chain is arranged in the hollow area of ​​the forward-moving frame. After the forward-moving frame moves forward to the air above the roadway, the vehicle-carrying plate can be lowered to the road surface to pick up and drop off vehicles.

[0003] This solution has simple structure, high safety, flexible layout, and can generate mechanical parking spaces above the roadside. However, this solution still has the following important defects:

[0004] 1. In order to ensure that the forward frame carrying the vehicle does not overturn when it is suspended and extended to the road surface, the rear column of the fixed frame must be firmly connected to the ground. During installation, reliable foundation construction must be done and embedded connectors must be set. Therefore, it will incur high foundation construction costs and installation costs, and take a long time. After the installation is completed, there may be safety hazards in the later stage due to the quality problems of the foundation construction.

[0005] 2. There are various shallowly buried municipal pipelines and sewage channels under the roadside of many roads. If the prior investigation is not sufficient, it may cause problems during foundation construction.

[0006] 3. This kind of small parking product often needs to be dismantled or moved due to changes in environmental conditions. Since the fixed frame is firmly connected to the foundation, when it needs to be dismantled or moved, it will incur high construction costs, and it will be troublesome to restore the ground to its original state, and it will also take a long time.

[0007] 4. When the front moving frame moves in mid-air, since there is no visible support underneath, it will create an unsafe visual threat feeling to people nearby regardless of whether there is a vehicle on board, and the user experience is not good enough. Summary of the invention

[0008] In order to solve the above-mentioned defects of the prior art, the present invention proposes a forward extending lifting double-layer parking device, as shown in the accompanying drawings, which is characterized by:

[0009] Its structure includes a fixed frame 1, a forward frame 2, a forward frame 3 and a longitudinal middle sliding beam 4;

[0010] The fixed frame 1 consists of longitudinal fixed frame side beams 11 on the upper left and right sides. The fixed frame side beams 11 are provided with longitudinal fixed frame side beam running rails 111 and fixed frame side beam auxiliary guide rails 112;

[0011] The forward moving frame 2 consists of a forward moving frame front cross beam 211 and a forward moving frame rear cross beam 212, and longitudinal forward moving frame side beams 22 between the left and right ends of the forward moving frame front cross beam 211 and the forward moving frame rear cross beam 212;

[0012] The front part of the forward moving frame side beam 22 is equipped with forward moving frame front wheels 221, and the rear part is equipped with forward moving frame rear wheels 224;

[0013] The forward moving support 3 consists of longitudinal forward moving support side beams 32 on the upper left and right sides. The forward moving support side beams 32 are provided with longitudinal forward moving support side beam running rails 321 and longitudinal forward moving support side beam auxiliary guide rails 322; Below the front end of the forward moving support side beam 32, a forward moving support hanging column 31 is installed, and a moving column foot 5 is installed at the bottom end of the forward moving support hanging column 31;

[0014] The bottom surface height position of the moving column foot 5 can be changed and locked between the upper limit position and the lower limit position;

[0015] The middle sliding beam 4 consists of a middle sliding beam front guide wheel 421, a middle sliding beam middle front guide wheel 422, a middle sliding beam middle rear guide wheel 423, and a middle sliding beam rear guide wheel 424 installed on both sides of the middle sliding beam main body plate 41;

[0016] The left and right forward moving support side beam auxiliary guide rails 322 of the forward moving support 3 respectively form left and right two-section three-piece telescopic sliding pairs with the left and right fixed frame side beam auxiliary guide rails 112 of the fixed frame 1 through the left and right middle sliding beams 4;

[0017] When the moving column foot 5 is in the upper limit position, the forward moving support 3 can move between the front and rear two limit positions by means of the telescopic sliding pair; The forward moving support 3 reaching the rear limit position is located above the fixed frame 1, and the forward moving support 3 reaching the front limit position is located above the road surface;

[0018] When the forward moving support 3 reaches the front limit position, the moving column foot 5 can be lowered to the lower limit position and locked after contacting the road surface;

[0019] After the forward moving support 3 reaches the front limit position, the forward moving frame 2 can move between above the fixed frame 1 and above the road surface along the fixed frame side beam running rails 111 and the forward moving support side beam running rails 321 by means of the forward moving frame front wheels 221 and the forward moving frame rear wheels 224;

[0020] There is a vehicle loading plate 6 in the hollow area of the forward moving frame 2, and the vehicle loading plate 6 is hung by a forward moving frame loading plate lifting chain 23 below the forward moving frame front cross beam 211 and the forward moving frame rear cross beam 212;

[0021] After the front shift frame 2 is shifted forward above the road surface, the car-carrying board 6 can be lowered to the road surface to pick up and drop off the vehicle 7.

[0022] Compared with the prior art, the front shift frame 3 that is suspended and shifted forward proposed by the present invention and the front shift frame 2 that hoists the car-carrying board operate separately. After the front shift frame 3 is shifted forward in place, the moving column foot 5 below the front shift frame suspension column 31 first descends and lands on the ground, forming a rigid column that supports the front shift frame 3. After that, the car-carrying board 6 is then shifted forward to above the road surface following the front shift frame 2. This forms a very stable, safe, and reliable operation process, and no longer requires the fixed frame to be firmly installed on the ground. As long as the surface of the hard ground meets the general load requirements, it can be directly placed like a four-column table to complete the installation, without the need for foundation construction on the road surface that damages the road surface. When needed, it can be moved at any time, and no bad marks will be left on the ground surface. Because the pressure of the column feet of the equipment on the ground is not high, the municipal pipelines below the ground surface will not be easily damaged after the equipment is placed. This feature is obviously very conducive to the popularization and implementation of the product.

[0023] Preferably,

[0024] Between the front shift frame front wheel 221 and the front shift frame rear wheel 224 of the front shift frame side beam 22, a front shift frame front middle wheel 222 and a front shift frame rear middle wheel 223 are provided;

[0025] When the front shift frame 3 is moved to the front limit position, the rear end of the front shift frame side beam running rail 321 is located in front of the front end of the fixed frame side beam running rail 111, and the distance therebetween is less than the wheelbase between the front shift frame front wheel 221 and the front shift frame front middle wheel 222, and is also less than the wheelbase between the front shift frame rear middle wheel 223 and the front shift frame rear wheel 224;

[0026] When the front shift frame 2 is located at the rear limit position, the front shift frame front middle wheel 222 and the front shift frame rear wheel 224 are supported by the fixed frame side beam running rail 111; when the front shift frame 2 is located at the front limit position, the front shift frame front wheel 221 and the front shift frame rear middle wheel 223 are supported by the front shift frame side beam running rail 321.

[0027] After adding the front shift frame front middle wheel 222 and the front shift frame rear middle wheel 223, the front shift frame 3 is allowed to be shifted forward to a farther distance, so that the car-carrying board 6 after landing can maintain a sufficient safety distance from the fixed frame 1, so that when the vehicle enters and exits the car-carrying board, it does not have to be close to the fixed frame and other vehicles on the roadside, optimizing the user experience.

[0028] Preferably,

[0029] The front shift frame front wheel 221 and the front shift frame front middle wheel 222 are synchronously driven by a driving mechanism. Alternatively, the front shift frame rear wheel 224 and the front shift frame rear middle wheel 223 are synchronously driven by a driving mechanism.

[0030] Preferably,

[0031] When the forward shift frame 2 is in the rear limit position, the forward shift frame side beam traveling rail 321 does not contact the forward shift frame front wheel 221 and the forward shift frame rear middle wheel 223.

[0032] Preferably,

[0033] The moving column foot 5 includes a moving column foot base body 51 connected to the bottom of the forward shift frame suspension column 31,

[0034] In the middle of the moving column foot base body bottom plate 512 at the bottom end of the moving column foot base body 51, there is a moving column foot base body bottom plate hole 5121;

[0035] The moving column foot base body bottom plate hole 5121 is equipped with a moving column foot main screw 53;

[0036] The bottom of the moving column foot main screw 53 is connected to the moving column foot bottom plate 52;

[0037] After the upper part of the moving column foot main screw 53 is screwed into the moving column foot screw locking nut 531 first, it is then screwed upward into the moving column foot lifting block bottom screw hole 542 of the moving column foot lifting block 54 in the moving column foot base body 51;

[0038] The moving column foot lifting block 54 can be transformed and locked between the upper limit position and the lower limit position under the drive of the transmission mechanism.

[0039] Preferably,

[0040] When the forward shift frame 3 moves forward, the middle sliding beam 4 is driven by the deceleration linkage mechanism and moves forward synchronously at half the forward speed of the forward shift frame 3;

[0041] The transmission mechanism is arranged along the forward shift frame suspension column 31 and the forward shift frame side beam 32. The transmission mechanism includes a column foot cross drive rod end convex 324 located at the rear end of the column foot cross drive rod 323;

[0042] The column foot cross drive rod end convex 324 is pushed and pulled forward within a limited distance by the elastic mechanism;

[0043] When the column foot cross drive rod end convex 324 is pushed and pulled to the front limit position by the elastic mechanism, the moving column foot lifting block 54 is driven by the transmission mechanism to rise to the upper limit position;

[0044] The middle sliding beam 4 is provided with a middle sliding beam column foot lifting drive block 45. When the forward shift frame 3 is about to reach the front limit position, the column foot cross drive rod end convex 324 is pushed and moved backward by the middle sliding beam column foot lifting drive block 45, and the middle sliding beam column foot lifting drive block 45 is driven by the transmission mechanism to drop to the lower limit position and lock, so that the moving column foot bottom plate 52 contacts the road surface.

[0045] The above preferred features simplify the transmission mechanism and improve the operation difficulty. Other more specific beneficial effects will be further described in the description of the embodiments.

[0096] Example 1 of the present invention is as Figures 1 to 22 shown.

[0097] See Figure 1 、 Figure 2 , which is an implementation scheme of a forward - extending and lifting double - layer parking equipment with a self - driving parking space below designed according to the principle of the present invention. Its main components include a fixed frame 1, a forward - moving frame 2 arranged above the fixed frame 1, a forward - moving bracket 3 installed between the fixed frame 1 and the forward - moving frame 2, and two middle sliding beams 4 for slidably connecting the fixed frame 1 and the forward - moving bracket 3.

[0098] In this embodiment, the left - right length of the fixed frame 3 is 6 meters and the depth is 2.5 meters, which is the same as the standard ground parking space marking size range, so as to be directly applied to the roadside marked parking spaces. The net clearance height below the fixed frame is 2.2 meters to accommodate general vehicles parked in the self - driving parking space below.

[0099] See Figure 3, the fixing frame 1 includes two front fixing frame columns 121 and two rear fixing frame columns 122. Fixing frame adjustable floor bolts 15 are installed at the bottom of the fixing frame columns to facilitate the adjustment of the equipment level on uneven installation sites and ensure that each column foot lands evenly. The fixing frame adjustable floor bolts 15 are pressed on four fixing frame adjustable floor bolt pads 151 on the ground. Since the fixing frame adjustable floor bolt pads 151 have a ground pressure area of several hundred square centimeters, and the total weight of the equipment components and the vehicle, which is about 4 to 5 tons, is distributed on the four columns with a load of only a little over one ton, it can be directly placed on a general hard road surface that meets the construction specification requirements without digging a foundation pit for reinforcement. When it is necessary to arrange the equipment closely in rows on site, the column feet of adjacent equipment can share the fixing frame adjustable floor bolt pads 151.

[0100] See Figure 22 , practice has proved that when a ground vehicle enters the self-propelled parking space under the fixing frame 3 in a reverse parking manner, the two front fixing frame columns 121 of the fixing frame 3 will provide guidance and assistance to the driver like a marker pole, rather than increasing the driver's operation difficulty.

[0101] On the top surface of the fixing frame side beams 11 on the upper left and right sides of the fixing frame 1 are the fixing frame side beam running rails 111, and on the inner side surface are the fixing frame side beam secondary rails 112 formed by two symmetric V-shaped cross-section sheet metal bending parts up and down.

[0102] See Figure 1 , Figure 2 , at the left and right positions near the rear side below the fixing frame 1, two wheel stoppers 8 are installed to facilitate guiding and restricting the correct parking range of the vehicle reversing into the area under the fixing frame.

[0103] See Figure 4 , Figure 9 , the left and right sides of the forward moving frame 3 are also forward moving frame side beams 32 made of sheet metal bending. The top surface of the forward moving frame side beam 32 serves as the forward moving frame side beam running rail 321, and on the outer side surface of the forward moving frame side beam 32 are two symmetric V-shaped cross-section forward moving frame side beam secondary rails 322 formed by sheet metal bending parts up and down. At the lower left and right front corners of the forward moving frame side beam 32, a forward moving frame lifting column 31 made of rectangular steel pipe is installed respectively. The bottom of the forward moving frame lifting column 31 is inserted into the moving column foot 5. See Figure 1 , Figure 2 The enlarged view of

[0104] The structure of the middle sliding beam 4 is as shown in Figure 5As shown in the figure, on both sides of the middle sliding beam main body plate 41, V-grooved middle sliding beam front guide wheels 421, middle sliding beam middle front guide wheels 422, middle sliding beam middle rear guide wheels 423, and middle sliding beam rear guide wheels 424 are coaxially installed. Inside the openings at the lower parts of the front and rear ends of the middle sliding beam main body plate 41, middle sliding beam end winding wheels 43 with vertical shafts are installed. The wire rope type middle sliding beam transmission chain 44 bypasses the front and rear middle sliding beam end winding wheels 43 and forms a tightened closed loop under the lower sides of both sides of the middle sliding beam main body plate 41.

[0105] See Figure 6 、 Figure 7 、 Figure 9 、 Figure 19 , the V-shaped profile side beam secondary guide rails 322 of the forward moving frame 3 respectively form left and right two-section three-stage telescopic sliding pairs with the V-shaped profile fixed frame side beam secondary guide rails 112 of the fixed frame 1 by means of the V-shaped guide wheels of the middle sliding beam 4, so that the forward moving frame 3 can be suspended and moved forward from above the fixed frame 1 to above the road surface. When the forward moving frame 3 makes a forward movement, the moving column feet 5 of the forward moving frame suspension column 31 are all at a suspended height about 4 centimeters from the bottom, and will not rub against the flat road surface. The power for the forward and backward movement of the forward moving frame 3 comes from the transmission mechanism installed on the fixed frame 1. See, 7 and Figure 19 , this transmission mechanism includes a plurality of forward moving frame drive chain idler wheels 171 arranged along the fixed frame side beam 11 and the fixed frame rear cross beam 132, and a circulating closed and tightened synchronous belt type forward moving frame drive chain 17 driven by a forward moving frame drive motor 174. Two fixed frame middle sliding beam chain connection blocks 18 on the forward moving frame drive chain 17 are respectively connected to the middle sliding beam transmission chain external connection points 441 under the lower parts of the left and right middle sliding beams 4. The two middle sliding beam transmission chain external connection points 441 located on both sides of the middle sliding beam main body plate 41 of the middle sliding beam 4 are respectively connected to the fixed frame middle sliding beam chain connection block 18 and the forward moving frame middle sliding beam chain connection block 34. After the forward moving frame drive motor 174 is started, the forward moving frame drive chain 17 drives the middle sliding beam 4 to move forward, and the middle sliding beam 4 then drives the forward moving frame 3 to move forward synchronously at twice the speed.

[0106] See Figure 8 , the forward moving frame 2 is composed of a forward moving frame front cross beam 211 and a forward moving frame rear cross beam 212, and longitudinal forward moving frame side beams 22 located between the left and right ends of the forward moving frame front cross beam 211 and the forward moving frame rear cross beam 212. A forward moving frame front wheel 221 is installed below the front end of the forward moving frame side beam 22, and a forward moving frame rear wheel 224 is installed below the rear end. A forward moving frame front middle wheel 222 is provided about 30 centimeters away from the forward moving frame front wheel 221, and a forward moving frame rear middle wheel 223 is provided about 30 centimeters away from the forward moving frame rear wheel 224.

[0107] The two forward moving frame front wheels 221 and the two forward moving frame front middle wheels 222 can rotate synchronously under the drive of the forward moving frame translation motor 26 through the forward moving frame translation drive chain 261, the forward moving frame translation synchronous shaft 27, and the forward moving frame translation chain 24.

[0108] The forward-shifting frame hoisting motor 25 can drive the four forward-shifting frame carrier hoisting chains 23 with their lower ends hanging the carrier vehicle plate 6 to perform lifting operations through the forward-shifting frame carrier hoisting chain 23 and the forward-shifting frame hoisting drive shaft 28 via the chain group transmission mechanism arranged in the front cross beam 211 and the rear cross beam 212 of the forward-shifting frame.

[0109] See Figure 7 , the power supply and control lines of the forward-shifting frame 3 are provided by the drag chain groove 161 and the drag chain 16 on the fixed frame 1. Similarly, the forward-shifting frame 3 can also be powered in a similar manner.

[0110] See Figure 1 , Figure 9 and Figure 10 . When the forward-shifting frame 2 is in the homing state at the rear limit position as shown in Figure 10 , the fixed frame side beam running rail 111 supports the rear wheel 224 of the forward-shifting frame and the front and middle wheels 222 of the forward-shifting frame. Depending on the pre-designed dimensions of the relevant components, when the forward-shifting frame 2 is in the homing state, there will be a gap of about 2 mm between the rail surface of the forward-shifting frame side beam running rail 321 and the front wheel 221 and the rear and middle wheels 223 of the forward-shifting frame, and they will not contact each other. At this time, the forward-shifting frame side beam running rail 321 will avoid bearing the pressure and frictional resistance of the forward-shifting frame 2, so that the independent forward movement can be carried out more easily.

[0111] See Figure 10 , Figure 11 and Figure 12 , when the system starts the vehicle access operation, the forward-shifting frame 3 together with the middle sliding beam 4 is pushed forward about 2.9 m to reach above the road surface. During the forward movement of the forward-shifting frame 3, the moving column foot 5 below the hoisting column 31 of the forward-shifting frame is in a suspended state of retracting upward and will not contact the road surface. Since the overall structural weight of the forward-shifting frame 3 is much smaller than the total weight of the fixed frame 1, the forward-shifting frame 2, and the carrier vehicle plate 6 in the stationary state, according to the lever principle, the forward-suspended forward-shifting frame 3 is not sufficient to drive the fixed frame 1 to tilt forward.

[0112] See Figure 13 , after the forward-shifting frame 3 moves forward in place, the moving column foot 5 descends to the ground, making the hoisting column 31 of the forward-shifting frame a rigid column supporting the front end of the side beam 32 of the forward-shifting frame. After that, the forward-shifting frame 2 can start to move forward. Of course, in actual operation, to improve the operation efficiency, the forward-shifting frame 2 can start to move forward slowly when the forward-shifting frame 3 is about to move forward in place. When the moving column foot 5 lands, the forward-shifting frame 2 has only moved forward a few tens of centimeters, and the overall center of gravity of the equipment and the vehicle will not move forward to a dangerous position that may cause tipping.

[0113] When the forward-shifting frame 2 starts to move forward at the beginning, the front and middle wheels 222 and the rear wheels 224 of the forward-shifting frame bear the self-weight and load of the forward-shifting frame 2.

[0114] See Figure 14 When the front shift frame 2 continues to move forward, the front wheels 221 of the front shift frame will enter above the traveling rail 321 of the side beam of the front shift frame. However, since the front middle wheels 222 of the front shift frame do not leave the traveling rail 111 of the side beam of the fixed frame at this time, the tread surface of the front wheels 221 of the front shift frame is still higher than the traveling rail 321 of the side beam of the front shift frame, and there is still a gap of about 2 millimeters or less between the wheel and the rail, and the wheel body is still in a suspended state.

[0115] See Figure 15 When the front shift frame 2 continues to move forward and the front middle wheels 222 of the front shift frame are separated from the traveling rail 111 of the side beam of the fixed frame, the front wheels 221 of the front shift frame will slightly descend and contact the tread surface of the traveling rail 321 of the side beam of the front shift frame. At this time, the front shift frame 2 is supported by the front wheels 221 and the rear wheels 224 of the front shift frame.

[0116] See Figure 16 and Figure 17 and Figure 18 When the front shift frame 2 continues to move forward and the front middle wheels 223 of the front shift frame enter above the tread surface of the traveling rail 321 of the side beam of the front shift frame, the rear wheels 224 of the front shift frame will also be separated from the traveling rail 111 of the side beam of the fixed frame, so that the front shift frame 2 is supported by the front wheels 221 and the front middle wheels 223 of the front shift frame.

[0117] See Figure 20 and Figure 21 In order to meet the requirements of safety specifications, mutually paired optoelectronic detection devices are provided on the front vertical column 121 of the fixed frame and the suspension column 31 of the front shift frame. During the forward and backward movement of the front shift frame 3 and the lifting and lowering movement of the car carrier 6, an infrared laser beam 9 safety fence that encloses on all four sides is formed between these optoelectronic detection devices. The range of the optoelectronic safety fence will change synchronously with the forward and backward movement of the front shift frame 3. As can be seen from Figure 21 Since the front shift frame 2 with multiple sets of guide wheels is adopted in this embodiment, the front shift frame 3 can move forward significantly towards the road surface. After the car carrier 6 lands, there is a loose distance of about 0.6 meters between the vehicle 7 entering and leaving the car carrier 6 and the front vertical column 121 of the fixed frame, and the user experience is good.

[0118] A front shift frame decorative plate 29 and a front shift frame decorative plate 36 can be installed on the front part of the front shift frame 2 and the front shift frame 3.

[0119] After the car carrier 6 rises to the in-place position, the front shift frame 2 first retracts to the home position. Then, the moving column foot 5 rises, and the front shift frame 3 moves backward to the home position, forming the home standby state shown in Figure 22 Due to the existence of the middle longitudinal beam 133 of the fixed frame, even if the chain breaks, the car carrier 6 will be immediately caught by the middle longitudinal beam 133 of the fixed frame, and a more serious overturning and falling accident will not occur. Therefore, the space below the fixed frame 1 is a reliable safety space.

[0120] Embodiment 2 is as shown in Figures 23 to 29as shown

[0121] This is the application solution of the movable column foot 5 that can be applied to Embodiment 1.

[0122] See Figure 23 , the movable column foot 5 is installed in the bottom cavity of the forward moving frame suspension column 31 made of square steel pipe.

[0123] See Figure 24 、 Figure 25 , the movable column foot 5 includes a movable column foot base body 51 enclosed by steel plates. There is a movable column foot base body bottom plate hole 5121 in the middle of the movable column foot base body bottom plate 512 at the bottom end of the movable column foot base body 51.

[0124] The movable column foot base body bottom plate hole 5121 is equipped with a movable column foot main screw 53, and the bottom of the movable column foot main screw 53 is connected to the movable column foot bottom plate 52.

[0125] After the upper part of the movable column foot main screw 53 is screwed into the movable column foot screw locking nut 531 first, it is then screwed upward into the movable column foot lifting block bottom screw hole 542 of the movable column foot lifting block 54 in the movable column foot base body 51.

[0126] The upper part of the movable column foot lifting block 54 has a movable column foot lifting block top shaft 541 guided by the movable column foot vertical guide hole 514 on the movable column foot base body side plate 511.

[0127] The movable column foot lifting block top shaft 541 is hinged to the movable column foot three-hole plate swing shaft 562 of the movable column foot three-hole plate 56 by means of a movable column foot double-hole strut 55. The movable column foot three-hole plate 56 is hinged to the movable column foot main shaft hole 516 on the movable column foot base body side plate 511 by a movable column foot three-hole plate fixed shaft 561.

[0128] The movable column foot three-hole plate drive shaft 563 of the movable column foot three-hole plate 56 is limited by the movable column foot base body arc-shaped limit hole 515, so that the movable column foot three-hole plate 56 can only swing between two extreme angular positions.

[0129] A movable column foot drive motor 58 is installed above the movable column foot base body side plate 511.

[0130] See Figures 26 to 28 , the movable column foot drive motor shaft 581 drives the movable column foot three-hole plate 56 to swing within a limited angular range through the mutually hinged movable column foot drive swing rod 59, movable column foot drive connecting rod 57 and movable column foot three-hole plate drive shaft 563, and drives the movable column foot lifting block 54, movable column foot main screw 53, and movable column foot bottom plate 52 to move up and down.

[0131] When the movable column foot bottom plate 52 drops to the lower limit position, due to the movable column foot double-hole strut 55 turning to a dead angle position, the height of the movable column foot bottom plate 52 is locked.

[0132] Based on the connecting rod principle, the moving column foot driving motor 58 can drive the three-hole plate 56 of the moving column foot to swing with a very small output torque.

[0133] Since the road surface cannot be perfectly flat, there must be a height difference in the area where the moving column foot 5 is located. Therefore, as Figure 29 shown, a locking nut 531 for the moving column foot screw is pre-installed on the main screw 53 of the moving column foot.

[0134] During equipment debugging, first loosen the locking nut 531 of the moving column foot screw, and then turn the main screw 53 of the moving column foot upward to the highest position. After the front support 3 moves forward in place, if the height of the bottom plate 52 of the moving column foot from the ground exceeds the preset limit value of 4 cm, the moving column foot 5 is driven to descend by the system. Then, by adjusting the locking nut 531 of the moving column foot screw and the main screw 53 of the moving column foot, the bottom plate 52 of the moving column foot is adjusted to the ground-touching position and tightened and locked.

[0135] Embodiment 3 is as Figure 30 、 Figure 31 shown.

[0136] In order to drive the moving column foot 5 to descend and land through the forward movement of the front support 3 that is about to move forward in place, so as to replace the moving column foot driving motor 58, in this embodiment, a driving suspension rod 311 for the inner column foot is installed inside the suspension column 31 of the front support, and with the help of the three-hole transmission plate 312 at the upper end and the cross driving rod 323 for the column foot installed inside the side beam 32 of the front support.

[0137] There is an end convex 324 at the rear end of the cross driving rod 323 for the column foot.

[0138] The end convex 324 of the cross driving rod for the column foot is applied with a forward pulling force by the return pulling spring 325 of the cross driving rod for the column foot.

[0139] Referring to Figure 31 , the end convex 324 of the cross driving rod for the column foot passes through the window hole 326 of the end convex of the cross driving rod for the column foot and reaches the rearward movement channel of the lifting driving block 45 for the column foot on the bottom of the main body plate 41 of the middle sliding beam.

[0140] When the end convex 324 of the cross driving rod for the column foot is pulled to the front limit position by the elastic mechanism, the lifting block 54 of the moving column foot is driven to rise to the upper limit position through the above-mentioned connecting rod mechanism.

[0141] When the front support 3 is about to reach the front limit position, the end convex 324 of the cross driving rod for the column foot is pushed backward by the lifting driving block 45 for the column foot on the middle sliding beam, and through the above-mentioned connecting rod mechanism, the lifting driving block 45 for the column foot on the middle sliding beam is driven to descend to the lower limit position and locked, so that the bottom plate 52 of the moving column foot contacts the road surface.

[0142] Obviously, in addition to the above-mentioned linkage mechanism, between the convex end 324 of the cross drive rod of the column base and the drive shaft 563 of the three-hole plate of the moving column base, it can be achieved through a simpler handbrake wire, but the service life may be relatively low.

[0143] Below the fixing frame of the present invention, it can be set as a ground self-propelled parking space as described in the above embodiment, or can be arranged above the roadside sidewalk, above the green space, or even combined with the building.

[0144] On the rear column 122 of the fixing frame, a charging device can also be installed to provide a charging function for the ground self-propelled parking space.

[0145] A rain shelter can be set above the fixing frame 1, or a rain shelter that can move with the forward movement frame 2 can be set on the forward movement frame 2. The rain shelter can be combined with a photovoltaic panel to provide energy storage power for the equipment itself.

[0146] Since the force required to drive the forward movement frame 3 to move back and forth is very small after the forward movement frame 2 returns to its position, the forward movement of the forward movement frame 3 can be achieved by an electric drive method as in the above embodiment, or can be achieved by a safer and more controllable manual method.
