Detailed implementation manners

[0034] The present invention will be specifically described below with reference to the accompanying drawings.

[0035] A turnover and adjustable construction operation platform, as Figure 1-2As shown in the figure, it includes a chassis 1, a scissor lift 100 and a balance mechanism 8. The scissor lift 100 is arranged on the chassis 1, and the balance mechanism 8 is arranged on the scissor lift 100. It also includes an extension mechanism. The extension mechanism includes a support plate 2. The support plate 2 is arranged on the balance mechanism 8. The balance mechanism 8 can keep the support plate 2 always horizontal with the ground. A first driving motor 201 is installed at the rear part of the top of the support plate 2. The output shaft of the first driving motor 201 is fixedly connected to one end of a first screw rod 202. The other end of the first screw rod 202 is rotatably connected to the support plate 2. A telescopic push plate 203 is threadedly connected to the first screw rod 202. One side of the telescopic push plate 203 is fixedly connected to one end of a plurality of elastic telescopic rods 204. The other ends of the plurality of elastic telescopic rods 204 are all fixedly connected to a connecting block 205. The tops of the plurality of connecting blocks 205 are respectively fixedly connected to a first extension plate 2061, a second extension plate 2062 and a bearing plate 206. The first extension plate 2061 is arranged close to the second extension plate 2062. Three bearing plates 206 are arranged on each of the mutually remote sides of the first extension plate 2061 and the second extension plate 2062. The tops of the bearing plate 206, the first extension plate 2061 and the second extension plate 2062 are in the same horizontal plane. A first telescopic rod 207 is arranged on the lower side of the bearing plate 206. The first telescopic rod 207 abuts against the bearing plate 206, the first extension plate 2061 and the second extension plate 2062. The first telescopic rod 207 is used to support the bearing plate 206, the first extension plate 2061 and the second extension plate 2062. Rollers 208 are rotatably connected to the ends of the bearing plate 206, the first extension plate 2061 and the second extension plate 2062. A driving mechanism is arranged on the chassis 1. The driving mechanism is used to drive the chassis 1 to move, and can make the chassis 1 perform planar movement and cross-floor movement. A braking mechanism is arranged on the chassis 1. The braking mechanism is used to brake the driving mechanism to keep stable, and can make the chassis 1 not displace during stair construction.

[0036] After the overall device is moved to the construction position, the front end of the overall device faces the construction wall. When there is an obstacle at the front end of the overall device, the front end of the overall device cannot approach the construction wall, and there is a distance between the construction worker and the construction wall, making it impossible to construct the construction wall. At this time, there is a certain distance between the roller 208 and the construction wall. Start the first driving motor 201. The output shaft of the first driving motor 201 drives the first screw rod 202 to rotate. The rotation of the first screw rod 202 drives the telescopic push plate 203 to move to the side away from the first driving motor 201. The telescopic push plate 203 drives a plurality of elastic telescopic rods 204 to move to the side away from the first driving motor 201. The plurality of elastic telescopic rods 204 drive the adjacent connecting blocks 205 to move. The connecting blocks 205 drive the bearing plate 206, the first extension plate 2061 and the second extension plate 2062 to move. The bearing plate 206, the first extension plate 2061 and the second extension plate 2062 slide on the first telescopic rod 207. The first telescopic rod 207 provides support for the bearing plate 206, the first extension plate 2061 and the second extension plate 2062. At the same time, the bearing plate 206, the first extension plate 2061 and the second extension plate 2062 drive the adjacent rollers 208 to move. When the bearing plate 206, the first extension plate 2061 and the second extension plate 2062 drive the adjacent rollers 208 to move, the front ends of the bearing plate 206, the first extension plate 2061 and the second extension plate 2062 are on the same horizontal plane. When the construction wall is a flat surface, after the bearing plate 206, the first extension plate 2061 and the second extension plate 2062 drive the adjacent rollers 208 to move, they can fit with the construction wall, and the front ends of the bearing plate 206, the first extension plate 2061 and the second extension plate 2062 can maintain the same horizontal plane. Then turn off the first driving motor 201. The output shaft of the first driving motor 201 no longer drives the first screw rod 202 to rotate. After the first screw rod 202 stops rotating, the telescopic push plate 203 is kept stable. After the telescopic push plate 203 stops moving, the plurality of elastic telescopic rods 204 on it are kept stable. After the plurality of elastic telescopic rods 204 stop moving, the adjacent connecting blocks 205 on them are kept stable. After the connecting blocks 205 stop moving, the adjacent bearing plate 206, the first extension plate 2061 and the second extension plate 2062 on them are kept stable. The bearing plate 206, the first extension plate 2061 and the second extension plate 2062 drive the adjacent rollers 208 to be kept stable. By moving the bearing plate 206, the distance between the construction worker and the construction wall can be shortened, making it more convenient for the construction worker to work. When the construction wall is an arc surface, after the bearing plate 206, the first extension plate 2061 and the second extension plate 2062 drive the adjacent rollers 208 to move, they cannot fit with the arc-shaped construction wall. When one of the rollers 208 abuts against the arc-shaped wall, there is still a gap between the other rollers 208 and the arc-shaped wall. The roller 208 abutting against the arc-shaped wall restricts the adjacent bearing plate 206, the first extension plate 2061 or the second extension plate 2062 from moving.At this time, the restricted bearing plate 206, the first extension plate 2061 or the second extension plate 2062 prevent the adjacent connection blocks 205 from moving. The restricted movement of the connection blocks 205 prevents the adjacent elastic telescopic rods 204 from moving. After the elastic telescopic rods 204 are restricted, they contract. At this time, the other rollers 208 that are not in contact with the arc-shaped wall can continue to move. The output shaft of the first driving motor 201 continues to drive the first screw rod 202 to rotate. The continuous rotation of the first screw rod 202 drives the telescopic push plate 203 to move away from the first driving motor 201. The telescopic push plate 203 continues to drive the plurality of elastic telescopic rods 204 to move away from the first driving motor 201. The plurality of elastic telescopic rods 204 continue to drive the adjacent connection blocks 205 to move. The connection blocks 205 continue to drive the adjacent bearing plate 206, the first extension plate 2061 or the second extension plate 2062 to move. The bearing plate 206, the first extension plate 2061 or the second extension plate 2062 continue to move on the first telescopic rod 207. When all the rollers 208 are in contact with the wall, the first driving motor 201 is turned off. The output shaft of the first driving motor 201 no longer drives the first screw rod 202 to rotate. After the first screw rod 202 stops rotating, the telescopic push plate 203 is kept stable. After the telescopic push plate 203 stops moving, the plurality of elastic telescopic rods 204 on it are kept stable. After the plurality of elastic telescopic rods 204 stop moving, the adjacent connection blocks 205 on them are kept stable. After the connection blocks 205 stop moving, the adjacent bearing plate 206, the first extension plate 2061 and the second extension plate 2062 on them are kept stable. The bearing plate 206, the first extension plate 2061 and the second extension plate 2062 drive the rollers 208 to be kept stable. After the construction workers complete their work, the first driving motor 201 is started. The first driving motor 201 drives the first screw rod 202 to rotate. The rotation of the first screw rod 202 drives the telescopic push plate 203 to move back to its original position. The telescopic push plate 203 drives the plurality of elastic telescopic rods 204 to move back to their original positions. The plurality of elastic telescopic rods 204 drive the adjacent connection blocks 205 to move back to their original positions. The connection blocks 205 drive the adjacent bearing plate 206, the first extension plate 2061 and the second extension plate 2062 to move back to their original positions. The bearing plate 206, the first extension plate 2061 and the second extension plate 2062 move back to their original positions on the first telescopic rod 207. At the same time, the bearing plate 206, the first extension plate 2061 and the second extension plate 2062 drive the adjacent rollers 208 to move. The elastic telescopic rods 204 are released and reset. After the bearing plate 206, the first extension plate 2061 and the second extension plate 2062 are reset, the fronts of the bearing plate 206, the first extension plate 2061 and the second extension plate 2062 are in a parallel state. Thus, the bearing plate 206, the first extension plate 2061 and the second extension plate 2062 of the extension mechanism are extended outward and reset. Through the plurality of elastic telescopic rods 204, the bearing plate 206, the first extension plate 2061 and the second extension plate 2062 can be displaced.The bearing plate 206, the first extension plate 2061 and the second extension plate 2062 are adapted to the irregular wall surface. The driving mechanism can drive the chassis 1 to move on the flat road surface and the stairs, making the movement of the whole device more convenient. When the chassis 1 stops on the stairs for construction, the braking mechanism can brake the driving mechanism to keep it stable. The stability of the driving mechanism enables the chassis 1 to drive the whole device to stay stably on the stairs.

[0037] As Figure 3 shown, the driving mechanism includes a second driving motor 301. The second driving motor 301 is installed in the middle of the rear side of the chassis 1. One end of the rotating shaft 302 is fixedly connected to the output shaft of the second driving motor 301, and the other end of the rotating shaft 302 is rotatably connected to the chassis 1. A main transmission component 303 is arranged on the rotating shaft 302. The main transmission component 303 is, from right to left, a first transmission gear, a first transmission disc, a second transmission gear and a second transmission disc. The first transmission disc is fixedly connected to the left end of the first transmission gear. The first transmission gear is rotatably connected to the rotating shaft 302. The second transmission disc is fixedly connected to the right end of the second transmission gear. The second transmission gear is rotatably connected to the rotating shaft 302. A moving screw 304 is rotatably connected to the chassis 1. A connecting plate 305 is threadedly connected to the moving screw 304. The lower part of the connecting plate 305 is rotatably connected to a two-way transmission disc 306. The two-way transmission disc 306 is rotatably connected to the rotating shaft 302. The two-way transmission disc 306 is in contact with the main transmission component 303.

[0038] As Figure 3 shown, the driving mechanism further includes a driving shaft 401. The driving shaft 401 is rotatably installed on the chassis 1. A driven component 402 is arranged on the driving shaft 401. The driven component 402 is, from right to left, a first belt pulley, a first driven gear and a second driven gear. The first belt pulley is fixedly connected to the first driven gear. The first driven gear is rotatably connected to the driving shaft 401. The second driven gear is fixedly connected to the driving shaft 401. The first driven gear of the driven component 402 meshes with the first transmission gear of the main transmission component 303. The second driven gear of the driven component 402 meshes with the second transmission gear of the main transmission component 303. The main transmission component 303 is used to provide power to the driven component 402. Two first slide rails 403 are symmetrically and fixedly connected to the middle of the rear end of the chassis 1. A moving frame 404 is slidably connected in the first slide rails 403. A transmission shaft 405 is rotatably installed in the moving frame 404. A second belt pulley is arranged on the transmission shaft 405. A belt is wound around the second belt pulley of the transmission shaft 405 and the first belt pulley of the driven component 402. A first driving wheel 406 is fixedly connected to the transmission shaft 405. A second screw 407 is rotatably connected to the rear part of the top end of the chassis 1. The moving frame 404 is threadedly connected to the second screw 407.

[0039] When the overall device needs to move on a flat ground, start the second drive motor 301. The output shaft of the second drive motor 301 drives the rotating shaft 302 to rotate, and the rotating shaft 302 drives the bidirectional transmission disk 306 to rotate. At this time, manually drive the moving screw 304 to rotate through the rocker at the left end of the moving screw 304. The moving screw 304 drives the connecting plate 305 to move to the right. After the connecting plate 305 drives the bidirectional transmission disk 306 to move to the right and contacts and meshes with the first transmission disk to drive the first transmission disk to rotate, the first transmission disk drives the first transmission gear to rotate. The first transmission gear meshes with the first driven gear of the driven assembly 402 to rotate. The first driven gear rotates on the drive shaft 401 and drives the first pulley to rotate. The first pulley drives the second pulley to rotate through the belt. The second pulley drives the transmission shaft 405 to rotate. The transmission shaft 405 drives the first drive wheel 406 to rotate. The first drive wheel 406 transmits power to the ground and drives the overall device to move. Thus, the movement of the overall device on a flat road surface is completed. When the overall device needs to move on the stairs, manually drive the moving screw 304 to rotate through the rocker at the left end of the moving screw 304. The moving screw 304 drives the connecting plate 305 to move to the left. After the connecting plate 305 drives the bidirectional transmission disk 306 to move to the left and contacts and meshes with the second transmission disk to drive the second transmission disk to rotate, the first transmission disk drives the second transmission gear to rotate. The second transmission gear meshes with the second driven gear of the driven assembly 402 to rotate. The second driven gear drives the drive shaft 401 to rotate. The drive shaft 401 provides power to the braking mechanism and can drive the overall device to move on the stairs.

[0040] As Figure 3-4 shown, the braking mechanism includes a triangular plate 501. Both ends of the drive shaft 401 penetrate through the chassis 1 and are fixedly connected with the triangular plate 501.

[0041] As Figure 3-4As shown, the braking mechanism further includes a limiting wheel 601. The other end of the rotating shaft 503 is fixedly connected to the limiting wheel 601. A plurality of limiting holes 602 are formed in the circumferential direction of the limiting wheel 601. A rotating plate 603 is rotatably connected to one side of the limiting wheel 601. The rotating plate 603 is L-shaped. A sliding rod 604 is slidably connected to the rotating plate 603. The sliding rod 604 is inserted into the limiting hole 602. The sliding rod 604 is used to limit the position of the limiting wheel 601. An activity frame 605 is fixedly connected to the two sliding rods 604. Limiting blocks 606 are symmetrically and fixedly connected to the top end of the activity frame 605. A groove is formed in the lower part of the rear end of the chassis 1. The limiting blocks 606 are snapped into the groove of the chassis 1. The groove of the chassis 1 is used to limit the position of the limiting blocks 606.

[0042] As Figure 5 shown, it further includes a flipping mechanism for extending the inclination of the extending mechanism. The flipping mechanism includes a third driving motor 701. The third driving motor 701 is installed at the front part of the top end of the chassis 1. A third screw rod 702 is rotatably installed on the chassis 1. The output shaft of the third driving motor 701 is fixedly connected to the third screw rod 702. A moving block 703 is threadedly connected to the third screw rod 702. One end of a second connecting rod 704 is hinged to the top end of the moving block 703. The other end of the second connecting rod 704 is hinged to an inclined frame 705. One side of the bottom end of the inclined frame 705 is hinged to the chassis 1. The other side of the inclined frame 705 abuts against the rear part of the top end of the chassis 1. The top end of the inclined frame 705 is fixedly connected to the scissor lift 100.

[0043] As Figure 6-7 shown, it further includes a balancing mechanism 8 for keeping the extending mechanism horizontal. The balancing mechanism 8 includes a rotating frame 801. The rotating frame 801 is fixedly connected to the scissor lift 100. A fourth driving motor 802 is installed in the rotating frame 801. A driving gear 803 is fixedly connected to the output shaft of the fourth driving motor 802. Arc-shaped grooves are symmetrically formed in the rotating frame 801. Arc-shaped plates 804 are slidably connected to the arc-shaped grooves of the rotating frame 801. A supporting plate 2 is fixedly connected to the top end of the arc-shaped plate 804. A semi-gear 805 is fixedly connected to the bottom end of the supporting plate 2. The driving gear 803 meshes with the semi-gear 805. An installation frame 806 is fixedly connected to the bottom end of the supporting plate 2. A balance rod 807 is hinged in the installation frame 806. Counterweight blocks 808 are fixedly connected to both ends of the balance rod 807. A trigger switch 809 is arranged in the installation frame 806. The counterweight block 808 contacts the trigger switch 809.

[0044] When the overall device needs to be constructed on a staircase or requires climbing a ladder, first move the overall device to the steps. Then, manually drive the second screw rod 407 to rotate by turning the handwheel on the second screw rod 407. The second screw rod 407 drives the moving frame 404 to move upward along the track of the first slide rail 403. The moving frame 404 drives the transmission shaft 405 to move upward. The transmission shaft 405 drives the first driving wheel 406 and the second belt pulley on it to move upward. After the moving frame 404 moves upward, the protruding part at the front end abuts against the inner top end of the first slide rail 403 and cannot move upward. At this time, there is a certain distance between the first driving wheel 406 and the ground after moving upward. Then, manually drive the moving screw rod 304 to rotate by turning the rocker on one side of the moving screw rod 304. The moving screw rod 304 drives the connecting plate 305 to move leftward. The connecting plate 305 drives the bidirectional transmission disk 306 to move leftward and no longer contacts the first transmission disk and contacts the second transmission disk. At this time, start the second driving motor 301. The output shaft of the second driving motor 301 drives the bidirectional transmission disk 306 to rotate. The bidirectional transmission disk 306 and the second transmission disk drive the second transmission gear to rotate. The second transmission gear meshes with the second driven gear to rotate. The second driven gear drives the drive shaft 401 to rotate. The drive shaft 401 drives the triangular plates 501 on both sides to rotate. The triangular plates 501 drive a number of adjacent second driving wheels 502 to rotate. A number of second driving wheels 502 contact the staircase and climb the ladder. After a number of second driving wheels 502 climb the staircase, the overall device tilts. At this time, the counterweight blocks 808 at both ends of the balance rod 807 drive the balance rod 807 to rotate around the connection point of the installation frame 806. When the overall device climbs the ladder upward, the front end of the overall device tilts upward. At this time, the top end of the rear counterweight block 808 presses against the adjacent trigger switch 809. After being pressed, the trigger switch 809 starts the fourth driving motor 802. At this time, the output shaft of the fourth driving motor 802 drives the driving gear 803 to rotate counterclockwise. The driving gear 803 meshes with the half gear 805 to rotate clockwise. The half gear 805 drives the support plate 2 to rotate clockwise. The support plate 2 drives the arc plate 804 to slide in the arc-shaped groove of the rotating frame 801. At the same time, the support plate 2 drives the installation frame 806 to rotate. The installation frame 806 drives the balance rod 807 and the trigger switch 809 to rotate. The balance rod 807 drives the counterweight block 808 to rotate. When the installation frame 806 rotates to be horizontal with the ground, the trigger switch 809 and the top end of the adjacent counterweight block 808 form a horizontal state. At this time, the counterweight block 808 no longer presses against the adjacent trigger switch 809. After the trigger switch 809 is not pressed, the output shaft of the fourth driving motor 802 stops rotating. The output shaft of the fourth driving motor 802 no longer drives the driving gear 803 to rotate. The driving gear 803 no longer meshes with the half gear 805 to rotate. The half gear 805 no longer drives the support plate 2 to rotate. The support plate 2 no longer drives the arc plate 804 to slide in the arc-shaped groove of the rotating frame 801. At the same time, the support plate 2 no longer drives the installation frame 806 to rotate.The installation frame 806 no longer drives the balance rod 807 and the trigger switch 809 to rotate, and the balance rod 807 no longer drives the counterweight 808 to rotate. At this time, the support plate 2 drives the extension mechanism thereon to form a horizontal state with the ground. When the overall device climbs down the ladder, the front end of the overall device faces the direction of the stairs. At this time, the top of the front counterweight 808 presses against the adjacent trigger switch 809. After being pressed, the trigger switch 809 activates the fourth drive motor 802. At this time, the output shaft of the fourth drive motor 802 drives the drive gear 803 to rotate clockwise. The drive gear 803 meshes with the half gear 805 to rotate counterclockwise. The half gear 805 drives the support plate 2 to rotate counterclockwise. The support plate 2 drives the arc plate 804 to slide in the arc groove of the rotating frame 801. At the same time, the support plate 2 drives the installation frame 806 to rotate. The installation frame 806 drives the balance rod 807 and the trigger switch 809 to rotate. The balance rod 807 drives the counterweight 808 to rotate. When the installation frame 806 rotates to be horizontal with the ground, the trigger switch 809 forms a horizontal state with the top of the adjacent counterweight 808. At this time, the counterweight 808 no longer presses against the adjacent trigger switch 809. After the trigger switch 809 is not pressed, the output shaft of the fourth drive motor 802 stops rotating. The output shaft of the fourth drive motor 802 no longer drives the drive gear 803 to rotate. The drive gear 803 no longer meshes with the half gear 805 to rotate. The half gear 805 no longer drives the support plate 2 to rotate. The support plate 2 no longer drives the arc plate 804 to slide in the arc groove of the rotating frame 801. At the same time, the support plate 2 no longer drives the installation frame 806 to rotate. The installation frame 806 no longer drives the balance rod 807 and the trigger switch 809 to rotate. The balance rod 807 no longer drives the counterweight 808 to rotate. At this time, the support plate 2 drives the extension mechanism thereon to form a horizontal state with the ground. Thus, it can be realized that the extension mechanism and the ground are always in a horizontal state.,

[0045] When the overall device climbs the ladder, the triangular plate 501 at the rear of the overall device rotates to drive the limit wheel 601 to rotate. Initially, the limit block 606 is inserted into the adjacent groove on the chassis 1. The limit block 606 is restricted, making the movable frame 605 unable to move. The movable frame 605 drives the sliding rod 604 away from the limit hole 602. The rotating plate 603 is restricted by the movable frame 605 and is in a vertical state. When the overall device needs to stay and construct at the stairs, the operator drives the movable frame 605 and the sliding rod 604 to move downward through the handle on the movable frame 605. The movable frame 605 drives the limit block 606 to disengage from the adjacent groove and enables the movable frame 605 to move. At the same time, the sliding rod 604 moves downward within the rotating plate 603. After the limit wheel 601 rotates, the limit hole 602 on it cannot ensure being perpendicular to the sliding rod 604. At this time, the operator drives the movable frame 605 to rotate counterclockwise to adjust the angle with the connection point of the rotating plate 603 and the triangular plate 501 as the center of the circle through the handle on the movable frame 605. The movable frame 605 drives the limit block 606 and the sliding rod 604 to rotate. The sliding rod 604 drives the rotating plate 603 to rotate counterclockwise with the connection point of the triangular plate 501 as the center of the circle. After the sliding rod 604 rotates, the operator presses the handle on the movable frame 605 to drive the movable frame 605 to move toward the side close to the limit wheel 601. The movable frame 605 drives the limit block 606 and the sliding rod 604 to move obliquely downward. The sliding rod 604 moves downward within the rotating plate 603 and inserts into the adjacent limit hole 602. Then, the operator drives the movable frame 605 to rotate counterclockwise with the connection point of the rotating plate 603 and the triangular plate 501 as the center of the circle through the handle on the movable frame 605. The movable frame 605 drives the limit block 606 and the sliding rod 604 to rotate. The sliding rod 604 drives the rotating plate 603 and the limit wheel 601 to rotate. The limit wheel 601 drives the rotating shaft 503 to rotate. The rotating shaft 503 drives the adjacent first connecting rod 504 on it to rotate clockwise with the connection point of the triangular plate 501 as the center of the circle. The first connecting rod 504 presses the brake block 506. The brake block 506 slides toward the adjacent second driving wheel 502 within the adjacent second slide rail 505 under the force and presses the adjacent second driving wheel 502. After several second driving wheels 502 are pressed, they cannot rotate and remain stable on the ground. After several second driving wheels 502 cannot rotate, the overall device can be kept stable. Then, the third driving motor 701 is started. The output shaft of the third driving motor 701 drives the third screw rod 702 to rotate. The third screw rod 702 rotates to drive the moving block 703 and the second connecting rod 704 to move toward the side away from the third driving motor 701. When the second connecting rod 704 moves, it presses the inclined frame 705. Initially, the bottom of the rear end of the inclined frame 705 abuts against the rear part of the top end of the chassis 1. When the inclined frame 705 is pressed, it rotates clockwise with the connection point of the chassis 1 as the center of the circle. The inclined frame 705 drives the scissor lift 100 to rotate. The scissor lift 100 drives the balance mechanism 8 and the extension mechanism on it to rotate. At the same time, the inclined frame 705 rotates with the connection point of the second connecting rod 704 as the center of the circle.The second connecting rod 704 rotates around the connection point of the moving block 703. The inclined frame 705 drives the scissors lift 100, the balance mechanism 8 and the extension mechanism to rotate, and then the extension mechanism is in a horizontal state, thus completing the deployment of the flipping mechanism. By rotating the inclined frame 705, the extension mechanism can be kept horizontal with the ground and the center of gravity of the whole device can be kept stable.,

[0046] When the construction is completed, the whole device needs to be moved. At this time, the worker drives the movable frame 605 to rotate clockwise around the connection point of the rotating plate 603 and the triangular plate 501 through the handle on the movable frame 605. The movable frame 605 drives the limit block 606 and the sliding rod 604 to rotate clockwise around the connection point of the rotating plate 603 and the limit wheel 601. The sliding rod 604 drives the rotating plate 603 to rotate. At the same time, the sliding rod 604 drives the limit wheel 601 to rotate clockwise in the limit hole 602. The limit wheel 601 drives the rotating shaft 503 to rotate. The rotating shaft 503 drives the adjacent first connecting rod 504 on it to rotate clockwise around the connection point of the triangular plate 501. The first connecting rod 504 drives the brake block 506 to slide towards the rotating shaft 503 in the adjacent second slide rail 505 under force. After the brake block 506 slides, it is reset and no longer presses the adjacent second driving wheel 502. After several second driving wheels 502 are released from the restriction of the brake block 506, they can move. Then the worker drives the movable frame 605 and the sliding rod 604 to move upward through the handle on the movable frame 605. The sliding rod 604 moves upward and disengages from the adjacent limit hole 602. At this time, the limit wheel 601 can rotate out of the restriction of the sliding rod 604. The movable frame 605 moves upward and drives the limit block 606 and the sliding rod 604 to move upward. The limit block 606 moves upward and is stuck in the adjacent groove on the chassis 1, thus completing the reset of the braking mechanism. Then the third driving motor 701 is started. The output shaft of the third driving motor 701 drives the third screw rod 702 to rotate. The third screw rod 702 rotates and drives the moving block 703 and the second connecting rod 704 to move towards the side close to the third driving motor 701. When the second connecting rod 704 moves, the supporting force on the inclined frame 705 gradually decreases. The inclined frame 705 rotates counterclockwise around the connection point of the chassis 1. The inclined frame 705 drives the scissors lift 100 to rotate. The scissors lift 100 drives the balance mechanism 8 and the extension mechanism on it to rotate. At the same time, the second connecting rod 704 rotates around the connection point of the inclined frame 705. The second connecting rod 704 rotates around the connection point of the moving block 703. After the inclined frame 705 drives the scissors lift 100, the balance mechanism 8 and the extension mechanism to rotate, they are reset. After the inclined frame 705 rotates, the rear part of the bottom end of the inclined frame 705 abuts against the rear part of the top end of the chassis 1, thus completing the reset of the flipping mechanism.

[0047] As Figure 8-10As shown, it further includes an expansion mechanism for providing deformation of the extension mechanism. The expansion mechanism includes an extension plate 901. The rear end of the support plate 2 is fixedly connected to the extension plate 901. The front side of the top end of the extension plate 901 is provided with an electric push rod 902. The telescopic end of the electric push rod 902 is fixedly connected to a first hinge frame 903. The third connecting rods 904 are symmetrically hinged inside the first hinge frame 903. The other ends of the third connecting rods 904 are both hinged to the telescopic push plate 203. The sliding plates 905 are symmetrically and slidably connected to the support plate 2. The first telescopic rod 207 is rotatably connected to the sliding plate 905. A special-shaped groove is formed in the middle of the telescopic push plate 203. A T-shaped frame 906 is slidably connected to the special-shaped groove of the telescopic push plate 203. The output shaft of the first drive motor 201 penetrates and is rotatably connected to the T-shaped frame 906. The third slide rails 907 are symmetrically formed at the top ends of the sliding plates 905. Elastic support blocks 908 are slidably connected to the third slide rails 907 respectively. A second telescopic rod 909 is fixedly connected inside the elastic support block 908. The second telescopic rod 909 abuts against the bottom ends of the bearing plate 206, the first extension plate 2061 and the second extension plate 2062. The second telescopic rod 909 provides support for the bearing plate 206, the first extension plate 2061 and the second extension plate 2062. A plurality of sliding blocks 910 are fixedly connected to the second telescopic rod 909. The bottom ends of the bearing plate 206, the first extension plate 2061 and the second extension plate 2062 are respectively provided with first sliding grooves 911 that cooperate with the sliding blocks 910.

[0048] As Figure 11-13As shown, the expansion mechanism further includes a lifting plate 1001. The lifting plate 1001 is arranged on the support plate 2. The lifting plate 1001 is composed of two right trapezoidal plates, which are the first sub-plate and the second sub-plate from right to left respectively. The bottom end of the lifting plate 1001 is fixedly connected with a translation track. A first hinge plate 1002 is slidably connected in the translation track of the lifting plate 1001. A limiting component is arranged on the lower side of the first hinge plate 1002. The limiting component is composed of a clamping rod, an elastic ejector rod and an elastic unlocking rod. The top end of the clamping rod is fixedly connected to the bottom end of the first hinge plate 1002. The lower part of the clamping rod is slidably connected to the support plate 2 in the vertical direction. A notch is formed in the lower front part of the clamping rod. The elastic ejector rod is slidably connected to the front part of the top end of the support plate 2. The elastic ejector rod is clamped into the notch of the clamping rod. The elastic ejector rod is used to limit the position of the clamping rod. The elastic unlocking rod is fixedly connected to the front part of the right end of the left sliding plate 905. The elastic unlocking rod is located on the left side of the elastic ejector rod. The elastic unlocking rod is in contact with the elastic ejector rod. The elastic unlocking rod is used to limit the position of the elastic ejector rod. The bottom end of the first hinge plate 1002 is symmetrically hinged with a third telescopic rod 1003. Second sliding grooves 1004 are formed at the bottom ends of the first expansion plate 2061 and the second expansion plate 2062. A second hinge frame 1005 is slidably connected in the second sliding grooves 1004. The other end of the third telescopic rod 1003 is hinged with the second hinge frame 1005. The bottom ends of the first sub-plate and the second sub-plate of the lifting plate 1001 are fixedly connected with a second hinge plate 1006. A support rod is arranged on the support plate 2. The support rod of the support plate 2 abuts against the bottom end of the second hinge plate 1006. The support rod of the support plate 2 is used to limit the position of the second hinge plate 1006. The bottom end of the second hinge plate 1006 is symmetrically hinged with a fourth telescopic rod 1007. The other end of the fourth telescopic rod 1007 is hinged with a third hinge frame 1008. The third hinge frame 1008 is fixedly connected with the adjacent first expansion plate 2061 / second expansion plate 2062.

[0049] As Figure 14 shown, it further includes a blocking frame 1101. A plurality of blocking frames 1101 are fixedly connected to the rear side of the top end of the bearing plate 206. A universal telescopic rod 1102 is fixedly connected between the plurality of blocking frames 1101. The universal telescopic rod 1102 can be telescopic when the plurality of blocking frames 1101 move in a staggered manner.

[0050] Initially, the bearing plate 206, the first extension plate 2061 and the second extension plate 2062 are closely attached. The sliding plate 905 on the left drives the elastic unlocking rod to squeeze the elastic ejector rod. The elastic unlocking rod is in a contracted state. The left corner of the elastic ejector rod is in contact with the upper part of the right end of the positioning rod. The first hinge bracket 903 drives the positioning rod to be in the initial position. The elastic ejector rod cannot be inserted into the notch of the positioning rod. When more people and goods need to be carried on the tops of the bearing plate 206, the first extension plate 2061 and the second extension plate 2062, the electric push rod 902 is started. The telescopic end of the electric push rod 902 drives the first hinge bracket 903 to extend towards the side close to the telescopic propulsion plate 203. The first hinge bracket 903 is stressed to squeeze the adjacent telescopic propulsion plate 203 to extend and slide towards both sides. When the telescopic propulsion plate 203 extends towards both sides, it maintains a horizontal state through the middle I-shaped bracket 906. The telescopic propulsion plate 203 drives the adjacent sliding plate 905 to slide on the support plate 2. The sliding plate 905 on the left drives the elastic unlocking rod of the limiting component to move. The elastic unlocking rod slides to the left and releases and no longer squeezes the elastic ejector rod. At the same time, the telescopic propulsion plate 203 drives the adjacent first telescopic rod 207 to extend towards both sides. At the same time, the third slide rail 907 on the telescopic propulsion plate 203 drives the elastic support block 908 therein to move. The elastic support block 908 drives the second telescopic rod 909 to extend towards both sides. The second telescopic rod 909 drives a plurality of sliding blocks 910 thereon to extend towards both sides. The plurality of sliding blocks 910 squeeze the adjacent first sliding groove 911 to drive the adjacent bearing plate 206, the first extension plate 2061 and the second extension plate 2062 to slide towards both sides. The first extension plate 2061 and the second extension plate 2062 drive the adjacent second hinge bracket 1005 and the third hinge bracket 1008 to move away from each other. The second hinge bracket 1005 drives the adjacent third telescopic rod 1003 to extend. After the two sides of the third telescopic rod 1003 extend to a certain extent, they drive the first hinge plate 1002 to extend upwards. The first hinge plate 1002 drives the positioning rod of the limiting component to extend upwards. The positioning rod restricts the movement track of the first hinge plate 1002, enabling the first hinge plate 1002 to extend vertically upwards. At this time, the left corner of the elastic ejector rod is in contact with the right end of the positioning rod. After the positioning rod moves upwards, the notch of the positioning rod coincides with the corner of the elastic ejector rod. The elastic ejector rod is released from the restriction of the positioning rod and is inserted into the notch of the positioning rod. The positioning rod is restricted by the elastic ejector rod and cannot descend. At this time, the positioning rod provides support for the first hinge plate 1002. The first hinge plate 1002 provides support for the first sub-board and the second sub-board, enabling the first sub-board and the second sub-board to maintain stability when bearing weight. At the same time, the third hinge bracket 1008 drives the adjacent fourth telescopic rod 1007 to extend upwards. After the fourth telescopic rod 1007 extends to a certain extent, it drives the second hinge plate 1006 to extend upwards. The first hinge plate 1002 squeezes the sliding track to drive the front part of the bottom end of the lifting plate 1001 to lift upwards. At the same time, the second hinge plate 1006 drives the rear part of the bottom end of the lifting plate 1001 to lift upwards. After the lifting plate 1001 lifts upwards,The top end of the lifting plate 1001 is on the same horizontal plane as the top ends of the bearing plate 206, the first extension plate 2061 and the second extension plate 2062, thereby completing the deployment of the expansion mechanism.

[0051] When the bearing plate 206, the first extension plate 2061 and the second extension plate 2062 extend forward, the protruding plate at the lower part of the rear end of the bearing plate 206 abuts against the second telescopic rod 909 and drives the second telescopic rod 909 to move. The second telescopic rod 909 provides support for the bearing plate 206. The second telescopic rod 909 drives the two elastic support blocks 908 to slide towards the side close to the connecting block 205 in the third slide rail 907. The two elastic support blocks 908 are stressed and contracted. After one of the bearing plate 206, the first extension plate 2061 or the second extension plate 2062 stops moving, the sliding block 910 in the first chute 911 at the bottom of the bearing plate 206, the first extension plate 2061 or the second extension plate 2062 is driven by the second telescopic rod 909 to slide forward in the first chute 911. When the first extension plate 2061 stops moving and the second extension plate 2062 continues to move, the first extension plate 2061 and the second extension plate 2062 are misaligned. The first extension plate 2061 and the adjacent first sub-plate stop moving. The first hinge plate 1002 slides in the translation track at the bottom of the first sub-plate. The second extension plate 2062 drives the adjacent second sub-plate to continue moving forward. At this time, the second sub-plate drives the adjacent translation track to slide forward. When the translation track slides forward, the first hinge plate 1002 in it is always in the translation track and provides support for the translation track. The translation track provides support for the second sub-plate. The second extension plate 2062 drives the adjacent fourth telescopic rod 1007 to move forward. The fourth telescopic rod 1007 drives the adjacent second hinge plate 1006 to move forward. The second hinge plate 1006 drives the second sub-plate to move forward, thereby completing the forward extension of the second sub-plate of the adjacent lifting plate 1001 driven by the second extension plate 2062. When the second extension plate 2062 drives the adjacent second sub-plate to reset, the second extension plate 2062 drives the adjacent fourth telescopic rod 1007 to move backward. The fourth telescopic rod 1007 drives the adjacent second hinge plate 1006 to move backward. The second hinge plate 1006 drives the second sub-plate to move backward. The second sub-plate moves backward to be on the same horizontal plane as the front end of the first sub-plate, thereby completing the reset of the adjacent second sub-plate driven by the second extension plate 2062.

[0052] When the second expansion board 2062 stops moving and the first expansion board 2061 continues to move, the second expansion board 2062 is misaligned with the first expansion board 2061. The second expansion board 2062 and the second sub-board inside it stop moving, and the first expansion board 2061 drives the adjacent first sub-board to continue moving forward. The first hinge plate 1002 slides within the translation track at the bottom of the second sub-board. At this time, the first sub-board drives the adjacent translation track to slide forward. When the translation track slides forward, the first hinge plate 1002 inside it always remains within the translation track and provides support for the translation track. The translation track provides support for the first sub-board. The first expansion board 2061 drives the adjacent fourth telescopic rod 1007 to move forward. The fourth telescopic rod 1007 drives the adjacent first hinge plate 1002 to move forward. The first hinge plate 1002 drives the first sub-board to move forward, thus completing the forward extension of the first sub-board of the adjacent lifting plate 1001 driven by the first expansion board 2061. When the first expansion board 2061 drives the first sub-board inside it to reset, the first expansion board 2061 drives the adjacent fourth telescopic rod 1007 to move backward. The fourth telescopic rod 1007 drives the adjacent second hinge plate 1006 to move backward. The second hinge plate 1006 slides on the limit frame and drives the first sub-board to move backward. The first sub-board drives the adjacent translation track to slide backward. When the translation track slides backward, the first hinge plate 1002 inside it always remains within the translation track and provides support for the translation track. The translation track provides support for the first sub-board, thus completing the reset of the adjacent first sub-board driven by the first expansion board 2061.

[0053] When the top areas of the bearing plate 206, the first extension plate 2061 and the second extension plate 2062 need to be reduced, the electric push rod 902 is activated. The telescopic end of the electric push rod 902 drives the first hinge frame 903 to contract toward the side away from the telescopic propulsion plate 203. The first hinge frame 903 drives the adjacent telescopic propulsion plates 203 to move closer to each other under force. The telescopic propulsion plates 203 drive the adjacent sliding plates 905 to slide closer to each other on the support plate 2. The left sliding plate 905 drives the elastic unlocking rod of the limiting component to move back to its original position. The elastic unlocking rod moves and presses the elastic ejector rod. The elastic ejector rod slides to the right to reset under force. After the elastic ejector rod slides to the right, it no longer restricts the clamping rod. After the clamping rod is released from the restriction of the elastic ejector rod, the first hinge frame 903 can move downward to reset. At the same time, the telescopic propulsion plates 203 drive the adjacent first telescopic rods 207 to contract. At the same time, the third slide rail 907 on the telescopic propulsion plates 203 drives the elastic support block 908 therein to move. The elastic support block 908 drives the second telescopic rod 909 to contract. The second telescopic rod 909 drives a plurality of sliding blocks 910 thereon to contract and move. The plurality of sliding blocks 910 squeeze the adjacent first sliding grooves 911 to drive the adjacent bearing plate 206, the first extension plate 2061 and the second extension plate 2062 to move closer to each other. The first extension plate 2061 and the second extension plate 2062 drive the adjacent second hinge frames 1005 and the third hinge frames 1008 to move closer to each other. The second hinge frame 1005 drives the adjacent third telescopic rods 1003 to contract. The contraction of the third telescopic rod 1003 drives the first hinge plate 1002 to descend. The first hinge plate 1002 drives the clamping rod to move downward to reset. At the same time, the third hinge frame 1008 drives the adjacent fourth telescopic rods 1007 to contract. The contraction of the fourth telescopic rod 1007 drives the second hinge plate 1006 to descend. The first hinge plate 1002 no longer presses the sliding track, causing the front part of the bottom end of the lifting plate 1001 to descend. At the same time, the second hinge plate 1006 drives the rear part of the bottom end of the lifting plate 1001 to descend. After the lifting plate 1001 descends, it resets to the initial position. The bearing plate 206, the first extension plate 2061 and the second extension plate 2062 are closely attached again, thus completing the reset of the expansion mechanism and the limiting component.

[0054] When the carrier plate 206 moves out of position with respect to the first extension plate 2061 and the second extension plate 2062, the blocking frame 1101 thereon moves out of position following the adjacent carrier plate 206, the first extension plate 2061 or the second extension plate 2062. At this time, the universal telescopic rod 1102 between the blocking frames 1101 rotates and extends with the connection point of two adjacent blocking frames 1101 as the center of the circle, so that the blocking frames 1101 can always be in a connected state. When the carrier plate 206 moves back to its original position with respect to the first extension plate 2061 and the second extension plate 2062, the blocking frame 1101 thereon moves back to its original position following the adjacent carrier plate 206, the first extension plate 2061 or the second extension plate 2062. At this time, the universal telescopic rod 1102 between the blocking frames 1101 rotates and contracts with the connection point of two adjacent blocking frames 1101 as the center of the circle, thus completing the reset of the universal telescopic rod 1102.
