Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a mechanical arm for construction engineering. Background Art

[0002] With the rapid development of modular buildings, the problems encountered in the installation process of modular buildings are becoming increasingly apparent. For example, during the installation of wall modules, how to hoist and move the wall modules from the transportation device to the designated installation location, and how to effectively support the wall modules to facilitate fixation during installation. The traditional installation method is to use a crane or a tower crane. Nowadays, a robotic arm that can be used to install wall modules is used to meet the construction requirements of today's modular buildings.

[0003] After searching, Chinese patent No. CN208100395U discloses a mechanical arm for construction, which includes: a base, wherein a working arm and a supporting arm are provided on the base, the bottom of the working arm is hinged to the base, the top of the working arm is provided with a mounting plate, the top of the supporting arm is hinged to a side of the working arm close to the supporting arm, and the bottom of the supporting arm is hinged to the base; the bottom of the base is provided with a moving mechanism for moving the base.

[0004] Although the above-mentioned construction robot arm can move the wall panel module to a specified position, it still has the following shortcomings:

[0005] 1. Since the staff can only observe the position of the screw holes on the wall panel module through the screw holes on the mounting plate when pushing the device, a staff is needed to direct the pushing direction when connecting the wall panel and the mounting plate together so that the screw holes on the wall panel and the screw holes on the mounting plate can be aligned and fit together, which wastes manpower.

[0006] 2. When the mounting plate and the wall module are fixed together, they need to be fixed with bolts. When the wall is transported to the designated location, the bolts need to be removed, which is troublesome and time-consuming.

[0007] Therefore, a mechanical arm for construction engineering is proposed. Summary of the invention

[0008] The object of the present invention is to provide a mechanical arm for construction engineering to solve the problem in the background art that multiple workers are needed to align the screw holes on the mounting plate with the screw holes on the wall module, which wastes manpower.

[0009] To achieve the above object, the present invention provides the following technical solutions:

[0010] A mechanical arm for construction engineering, comprising a base, a caster and a coaxial wheel are symmetrically mounted on the bottom wall of the base, the coaxial wheel comprises a rotating shaft mounted on the bottom wall of the base for horizontal rotation, tires are fixedly mounted on both ends of the rotating shaft, a telescopic rod and a first support rod are respectively mounted on the top wall of the base, the telescopic rod and the first support rod are hinged, a mounting plate is provided on the top of the telescopic rod, a first cavity is opened on the mounting plate, a partition plate of magnetic material is movably provided in the first cavity, a first spring connected to the first cavity is horizontally mounted on one side of the partition plate, a plurality of plug rods extending outside the mounting plate are horizontally and evenly inserted on the side wall of the first cavity on the side opposite to the first spring, a magnet is mounted on one end of the plug rod located in the first cavity, and a fixing mechanism is provided on the plug rod;

[0011] The fixing mechanism includes a second cavity opened on the insertion rod, a block extending into the second cavity is vertically and movably inserted on the insertion rod, a second spring is installed between the two blocks, a third cavity is opened on the partition, a thin tube extending into the third cavity is horizontally and movably inserted on the side wall of the second cavity, the thin tube is fixedly connected to the partition, a trigger mechanism cooperating with the block is provided in the first cavity, device grooves are symmetrically opened on the side walls of the mounting plate, a push plate is movably provided in the device groove, a pressurizing box for driving the push plate to move is installed on one side of the base, an air pipe connected to the device groove is provided on the pressurizing box, a warning light is installed on the side wall of the mounting plate on the opposite side of the push plate, and a switch connected in series with the warning light is provided in the first cavity.

[0012] During the working process, the staff pushes the handle installed on the base, so that the base can be moved under the joint action of the steering wheel and the coaxial wheel. When the base moves to the specified position, the extension length of the telescopic rod and the first support rod is adjusted so that the mounting plate installed at one end of the telescopic rod can reach the middle position of the wall module. After roughly adjusting the position of the mounting plate, the entire device is pushed toward the wall module. Since a magnet that repel each other with the partition is installed at one end of the insertion rod, the magnet and the partition repel each other in the initial state, thereby driving the insertion rod to extend out of the mounting plate, and at any time, the partition and the magnet are The repulsive force between them can make the plug rod extend out of the mounting plate. When the device is pushed toward the wall module, since a plurality of plug rods are horizontally and movably inserted on the side wall of the first cavity, some of the plug rods will pass through the screw holes on the wall module. In this process, since the plug rods that have not passed through the screw holes are in contact with the surface of the wall panel, and the wall panel is stationary while the device is moving, the plug rods in contact with the wall panel will be pushed, and the pushed plug rods will enter the first cavity. When the plug rods entering the first cavity come into contact with the partition, the plug rods will push the partition to move in the first cavity. During the movement of the partition, the first spring is squeezed, and the left wall of the partition The pressure in the cavity formed between the first cavity and the left side wall of the partition increases. At this time, the device is continued to be pushed, and the pressure in the cavity continues to increase. When the first spring is squeezed to the maximum, the plug rod passing through the screw hole has extended out of the surface of the wall panel, and the plug rod squeezed by the wall panel has completely entered the mounting plate. At this time, the switch of the warning light is squeezed by the partition, so that the warning light lights up, prompting the staff that the plug rod is in place to move the wall panel. At the same time, the trigger mechanism is operated. Therefore, the cavity formed between the left side wall of the partition and the first cavity begins to release pressure into the third cavity. Since the third cavity and the second cavity are connected by a thin tube The second spring is stretched to fix the wall panel and the mounting plate together, thereby preventing the wall panel from falling off during transportation. The block on the rod that is pushed back into the mounting plate by the wall panel is in contact with the mounting plate due to the surface of the rod.

[0013] When the wall panel is transported to the designated location, the staff steps on the pressurizing box to pressurize the device slot through the air pipe, thereby increasing the pressure in the device slot. When the pressure in the device slot increases, the push plate will move along the device slot, and gradually push the wall panel during the movement of the push plate. Since the force is mutual, when the wall panel is pushed, the push plate will be subjected to a reaction force. At this time, since the device slot is in a high pressure state and the push plate can slide in the device slot, the reaction force will act on the mounting plate. Since a rolling tire is installed on the base, the rolling friction between the tire and the ground is small. Therefore, the mounting plate subjected to the reaction force will drive the device to move away from the wall. At this time, the edge of the screw hole will be squeezed against the card block. Since the stretched second spring has a tendency to recover, the card block will retract into the insertion rod during the mutual squeezing between the card block and the edge of the screw hole. After the card block retracts into the insertion rod, when the push plate pushes the wall panel, the device will move away from the wall panel under the action of the reaction force, thereby quickly separating the wall panel from the mounting plate.

[0014] Preferably, a fixing block is installed on the side wall of the mounting plate, a fourth cavity is opened on the fixing block, a fixing rod connected to the telescopic rod is movably provided in the fourth cavity, and a third spring connected to the fixing rod is installed on the top wall and the bottom wall of the fourth cavity.

[0015] When the device passes through a road section with debris such as pebbles on the ground, the device will experience bumps. At this time, since the third spring connected to the fixed rod is installed on the top wall and the bottom wall of the fourth cavity, and the fixed rod and the telescopic rod are fixedly connected, when the base drives the telescopic rod to bump, the third spring can convert the kinetic energy of the device during the bumping process into elastic potential energy, thereby reducing the bump amplitude and preventing the deformation of the screw hole caused by collision between the insertion rod and the screw hole due to bumps.

[0016] Preferably, the trigger mechanism includes a push rod installed on the side wall of the first cavity, a conduit extending into the third cavity is horizontally installed on the side of the partition close to the push rod, a second support rod with the same length as the conduit is horizontally installed on the side wall of the partition above the conduit, and one end of the second support rod is hinged with a baffle that cooperates with the conduit.

[0017] Since only a part of the insertion rod will pass through the screw hole, the rest of the insertion rod will be attached to the wall panel and pushed by the wall panel. When the pushed insertion rod contacts the partition, it pushes the partition to move along the first cavity. During the movement of the partition, the pressure in the space formed between the left side wall of the partition and the first cavity increases and is in a high-pressure state. The push rod contacts the baffle which is in a vertical state in the initial state. At this time, the partition continues to move, and the push rod will push the baffle to rotate around the second support rod. At the moment the baffle rotates, the conduit port is exposed. Since the conduit connects the space and the second cavity, the pressure in the second cavity increases. Since the capillary connects the second cavity and the third cavity, the pressure in the third cavity will also increase. Since when the third cavity is in a high-pressure state, the block tends to move outward from the insertion rod, it triggers the block to extend.

[0018] Preferably, the pressurized box includes a shell, a guide rod is vertically installed on the inner bottom wall of the shell, a pressure plate is movably sleeved on the guide rod, a fourth spring is sleeved on the part of the guide rod located below the pressure plate, and an airbag connected to the inner bottom wall of the shell is installed on the bottom wall of the pressure plate.

[0019] In the initial state, the airbag is filled with gas, which pushes the pressure plate upward and moves it to the top of the guide rod. When the wall module is moved to the specified position, the insertion rod needs to be disengaged from the screw hole on the wall. At this time, the staff steps on the pressure plate downward to squeeze the airbag during the process of the pressure plate moving down along the guide rod. In this process, the fourth spring is compressed. At the same time, the gas in the airbag flows into the device slot through the air pipe. A large amount of gas enters the device slot, causing the pressure in the device slot to increase, thereby causing the push plate to move in the device slot, thereby pushing the wall panel, thereby causing the wall panel to be out of contact with the insertion rod. When the insertion rod is out of the socket, the staff no longer steps on the pressure plate. At this time, the squeezed fourth spring has a tendency to recover and pushes the pressure plate upward, causing the pressure plate to drive the airbag to extend, thereby preparing for stepping on the pressure plate again.

[0020] Preferably, a battery slot is provided on the mounting plate, a battery connected in series with the warning light is provided in the battery slot, a plurality of piezoelectric ceramics connected in series with the battery are installed on the bottom wall of the base, and a plurality of impact rods cooperating with the piezoelectric ceramics are evenly installed on the rotating shaft.

[0021] When the device is pushed, the tire drives the rotating shaft to rotate, and the impact rod vertically installed on the rotating shaft also rotates accordingly. During the rotation of the impact rod, it will hit the piezoelectric ceramics installed on the bottom wall of the base. The impacted piezoelectric ceramics generate electrical energy, which is then transmitted to the battery connected in series with it to charge the battery, thereby reducing the amount of electricity required to charge the battery from the outside and saving resources.

[0022] Preferably, a steel ball is movably embedded in the top of the fixing rod.

[0023] By movably embedding a steel ball at the top of the fixing rod, the sliding friction between the fixing rod and the fixing block can be converted into rolling friction, thereby reducing the friction force. When the device is pushed on a bumpy road, the fixing rod can move up and down in the fourth cavity more smoothly.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. In the process of pushing the base, since a plurality of plug rods are movably inserted on the mounting plate, it is not necessary for multiple workers to work together to accurately align the screw holes on the wall module, and some of the plug rods can pass through the screw holes to lift the wall module.

[0026] 2. After some of the rods enter the screw holes, the staff continues to push the base, so that the remaining rods are squeezed into the first cavity. In the process of the remaining rods gradually entering the first cavity, the partition is pushed, thereby increasing the pressure in the cavity where the first spring is located. When the first spring is fully compressed, the push rod pushes the baffle, and the cavity in a high-pressure state begins to relieve pressure. In the process of pressure relief, under the action of the thin rod, the pressure in the second cavity increases. Under the action of high pressure, the block on the rod extending out of the screw hole extends out, thereby fixing the wall panel to prevent the wall panel from falling off during transportation.

[0027] 3. There are debris on the ground of the construction site. Therefore, when the device passes through the ground with scattered debris, the fourth spring uses shock absorption to prevent the screw hole from colliding with the insertion rod and causing deformation of the screw hole.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] See also Figures 1 to 8 The present invention provides a mechanical arm for construction engineering, and the technical solution is as follows:

[0039] A mechanical arm for construction engineering, comprising a base 1, a caster 2 and a coaxial wheel 3 are symmetrically mounted on the bottom wall of the base 1, the coaxial wheel 3 comprises a rotating shaft 301 mounted horizontally and rotatably on the bottom wall of the base 1, tires 302 are fixedly mounted on both ends of the rotating shaft 301, a telescopic rod 4 and a first support rod 5 are respectively mounted on the top wall of the base 1, the telescopic rod 4 and the first support rod 5 are hinged, a mounting plate 6 is provided at the top end of the telescopic rod 4, a first cavity 30 is opened on the mounting plate 6, a partition plate 7 of magnetic material is movably provided in the first cavity 30, a first spring 8 connected to the first cavity 30 is horizontally mounted on one side of the partition plate 7, a plurality of insertion rods 9 extending to the outside of the mounting plate 6 are horizontally and evenly inserted on the side wall of the first cavity 30 on the side opposite to the first spring 8, a magnet 10 is mounted on one end of the insertion rod 9 located in the first cavity 30, and a fixing mechanism is provided on the insertion rod 9;

[0040] The fixing mechanism includes a second cavity 31 opened on the insertion rod 9, a block 11 extending into the second cavity 31 is vertically and movably inserted on the insertion rod 9, a second spring 12 is installed between the two blocks 11, a third cavity 32 is opened on the partition 7, a thin tube 13 extending into the third cavity 32 is horizontally and movably inserted on the side wall of the second cavity 31, the thin tube 13 is fixedly connected to the partition 7, a trigger mechanism cooperating with the block 11 is provided in the first cavity 30, device grooves are symmetrically opened on the side wall of the mounting plate 6, a push plate 14 is movably provided in the device groove, a pressurizing box 15 for driving the push plate 14 to move is installed on one side of the base 1, an air pipe 16 connected to the device groove is provided on the pressurizing box 15, a warning light 17 is installed on the side wall of the mounting plate 6 on the opposite side of the push plate 14, and a switch 18 connected in series with the warning light 17 is provided in the first cavity 30.

[0041] During the working process, the staff pushes the handle installed on the base 1, so that the base 1 can be moved under the joint action of the steering wheel and the coaxial wheel 3. When the base 1 moves to the specified position, the extension length of the telescopic rod 4 and the first support rod 5 is adjusted so that the mounting plate 6 installed at one end of the telescopic rod 4 can reach the middle position of the wall module. After roughly adjusting the position of the mounting plate 6, the whole device is pushed toward the wall module. Since a magnet 10 that repel each other with the partition 7 is installed at one end of the insertion rod 9, the magnet 10 and the partition 7 repel each other in the initial state, thereby driving the insertion rod 9 to extend out of the mounting plate 6, and at any time, the repulsion between the partition 7 and the magnet 10 The force can make the plug rod 9 extend out of the mounting plate 6. When the device is pushed toward the wall module, since a plurality of plug rods 9 are horizontally and movably inserted on the side wall of the first cavity 30, some of the plug rods 9 will pass through the screw holes on the wall module. In this process, since the plug rods 9 that have not passed through the screw holes are in contact with the surface of the wall panel, and the wall panel is stationary while the device is moving, the plug rods 9 in contact with the wall panel will be pushed, and the pushed plug rods 9 will enter the first cavity 30. When the plug rods 9 entering the first cavity 30 come into contact with the partition 7, the plug rods 9 will push the partition 7 to move in the first cavity 30. During the movement of the partition 7, the first spring 8 is squeezed, and the left side wall of the partition 7 is in contact with the first cavity The pressure in the cavity formed between the partition 7 and the first cavity 30 increases. At this time, the device is continued to be pushed, and the pressure in the cavity continues to increase. When the first spring 8 is squeezed to the maximum, the plug rod 9 passing through the screw hole has extended out of the surface of the wall panel, and the plug rod 9 squeezed by the wall panel completely enters the mounting plate 6. At this time, the switch 18 of the warning light 17 is squeezed by the partition 7, so that the warning light 17 lights up, prompting the staff that the plug rod 9 is in place to move the wall panel. At the same time, the trigger mechanism is operated. Therefore, the cavity formed between the left side wall of the partition 7 and the first cavity 30 begins to release pressure into the third cavity 32. Since the third cavity 32 and the second cavity 31 are connected through the capillary 13, Therefore, when the pressure in the third cavity 32 increases, the pressure in the second cavity 31 also increases accordingly. When the pressure in the second cavity 31 increases, the block 11 pulled by the second spring 12 in the initial state will have a tendency to extend out of the surface of the insertion rod 9. Therefore, the block 11 on the insertion rod 9 passing through the screw hole can extend out of the surface of the insertion rod 9, and the second spring 12 is stretched, which plays a role in fixing the wall panel and the mounting plate 6 together, and can prevent the wall panel from falling off during transportation. The block 11 on the insertion rod 9 that is pushed back into the mounting plate 6 by the wall panel is in contact with the mounting plate 6 due to the surface of the insertion rod 9. Therefore, this part of the block 11 can only fit tightly with the mounting plate 6.

[0042] When the wall panel is transported to the designated location, the staff steps on the pressurizing box 15 to pressurize the device slot through the air pipe 16, so that the pressure in the device slot can be increased. When the pressure in the device slot increases, the push plate 14 will move along the device slot, and gradually push the wall panel during the movement of the push plate 14. Since the force is mutual, when the wall panel is pushed, the push plate 14 will be subjected to a reaction force. At this time, since the device slot is in a high-pressure state and the push plate 14 can slide in the device slot, the reaction force will act on the mounting plate 6. Since the base 1 is equipped with a device that can The rolling friction between the tire 302 and the ground is relatively small, so the mounting plate 6 subjected to the reaction force will drive the device to move in the direction away from the wall. At this time, the edge of the screw hole will be squeezed with the block 11. Since the stretched second spring 12 has a tendency to recover, the block 11 will retract into the insertion rod 9 during the process of mutual squeezing between the block 11 and the edge of the screw hole. After the block 11 retracts into the insertion rod 9, the push plate 14 will push the wall panel under the action of the reaction force, and the device will move away from the wall panel, thereby quickly separating the wall panel from the mounting plate 6.

[0043] As an embodiment of the present invention, refer to Figure 2 and Figure 6 A fixing block 19 is installed on the side wall of the mounting plate 6, and a fourth cavity 33 is opened on the fixing block 19. A fixing rod 20 connected to the telescopic rod 4 is movably provided in the fourth cavity 33, and a third spring 21 connected to the fixing rod 20 is installed on the top wall and the bottom wall of the fourth cavity 33.

[0044] When the device passes through a road section with debris such as pebbles on the ground, the device will experience bumps. At this time, since the third spring 21 connected to the fixing rod 20 is installed on the top wall and the bottom wall of the fourth cavity 33, and the fixing rod 20 and the telescopic rod 4 are fixedly connected, when the base 1 drives the telescopic rod 4 to bump, the third spring 21 can convert the kinetic energy of the device during the bumping process into elastic potential energy, thereby reducing the bump amplitude, which prevents the insertion rod 9 from colliding with the screw hole due to the bump and causing deformation of the screw hole.

[0045] As an embodiment of the present invention, refer to Figure 8 The trigger mechanism includes a push rod 22 installed on the side wall of the first cavity 30, a conduit 23 extending into the third cavity 32 is horizontally installed on the side of the partition 7 close to the push rod 22, and a second support rod 24 with the same length as the conduit 23 is horizontally installed on the side wall of the partition 7 above the conduit 23, and a baffle 25 that cooperates with the conduit 23 is hinged at one end of the second support rod 24.

[0046] Since only a part of the insertion rod 9 will pass through the screw hole, the rest of the insertion rod 9 will be attached to the wall panel and pushed by the wall panel. When the pushed insertion rod 9 contacts the partition 7, the partition 7 is pushed to move along the first cavity 30. During the movement of the partition 7, the pressure in the space formed between the left side wall of the partition 7 and the first cavity 30 increases and is in a high-pressure state. The push rod 22 contacts the baffle 25 which is in a vertical state in the initial state. At this time, the partition 7 continues to move, and the push rod 22 will push the baffle 25 to rotate around the second support rod 24. At the moment when the baffle 25 rotates, the mouth of the conduit 23 is exposed. Since the conduit 23 connects the space and the second cavity 31, the pressure in the second cavity 31 increases. Since the capillary 13 connects the second cavity 31 and the third cavity 32, the pressure in the third cavity 32 will also increase. Since when the third cavity 32 is in a high-pressure state, the block 11 has a tendency to move outward from the insertion rod 9, it plays a role in triggering the block 11 to extend.

[0047] As an embodiment of the present invention, refer to Figure 5 The pressurizing box 15 includes a shell 1501, a guide rod 1502 is vertically installed on the inner bottom wall of the shell 1501, a pressure plate 1503 is movably sleeved on the guide rod 1502, a portion of the guide rod 1502 below the pressure plate 1503 is sleeved with a fourth spring 1504, and an air bag 1505 connected to the inner bottom wall of the shell 1501 is installed on the bottom wall of the pressure plate 1503.

[0048] In the initial state, the airbag 1505 is filled with gas, thereby pushing the pressure plate 1503 upward, so that the pressure plate 1503 moves to the top of the guide rod 1502. When the wall module is moved to the specified position, the insertion rod 9 needs to be separated from the screw hole on the wall. At this time, the staff steps on the pressure plate 1503 downward, so that the pressure plate 1503 moves down along the guide rod 1502 and squeezes the airbag 1505. In this process, the fourth spring 1504 is compressed, and the gas in the airbag 1505 flows through the air pipe 16. When the push plate 1503 is in contact with the insertion rod 9, a large amount of gas enters the device groove, causing the pressure in the device groove to increase, thereby moving the push plate 14 in the device groove, thereby pushing the wall panel, thereby making the wall panel break away from the contact with the insertion rod 9. When the insertion rod 9 is out of the socket, the staff no longer steps on the pressure plate 1503. At this time, the squeezed fourth spring 1504 has a tendency to recover and pushes the pressure plate 1503 upward, so that the pressure plate 1503 drives the airbag 1505 to extend, thereby preparing for stepping on the pressure plate 1503 again.

[0049] As an embodiment of the present invention, refer to Figure 3 and Figure 4A battery slot is provided on the mounting plate 6, in which a battery 26 connected in series with the warning light 17 is provided, a plurality of piezoelectric ceramics 27 connected in series with the battery 26 are installed on the bottom wall of the base 1, and a plurality of impact rods 28 cooperating with the piezoelectric ceramics 27 are evenly installed on the rotating shaft 301.

[0050] When the device is pushed, the tire 302 drives the rotating shaft 301 to rotate, and the impact rod 28 vertically installed on the rotating shaft 301 also rotates accordingly. During the rotation of the impact rod 28, it will hit the piezoelectric ceramic 27 installed on the bottom wall of the base 1. The impacted piezoelectric ceramic 27 generates electrical energy, which is then transmitted to the battery 26 connected in series with it to charge the battery 26, thereby reducing the amount of electricity charged by the outside world for the battery 26, thereby saving resources.

[0051] As an embodiment of the present invention, refer to Figure 6 A steel ball 29 is movably embedded at the top of the fixing rod 20 .

[0052] By movably embedding a steel ball 29 at the top of the fixing rod 20, the sliding friction between the fixing rod 20 and the fixing block 19 can be converted into rolling friction, thereby reducing the friction force. When the device is pushed on a bumpy road, the fixing rod 20 can move up and down in the fourth cavity 33 more smoothly.

[0053] Working principle: During the working process, the staff pushes the handle installed on the base 1, so that the base 1 can be moved under the joint action of the steering wheel and the coaxial wheel 3. When the base 1 moves to the specified position, the extension length of the telescopic rod 4 and the first support rod 5 is adjusted so that the mounting plate 6 installed at one end of the telescopic rod 4 can reach the middle position of the wall module. After roughly adjusting the position of the mounting plate 6, the entire device is pushed toward the wall module. Since a magnet 10 that repel each other with the partition 7 is installed at one end of the insertion rod 9, in the initial state, the magnet 10 and the partition 7 repel each other, thereby driving the insertion rod 9 to extend out of the mounting plate 6, and at any time, the repulsive force between the partition 7 and the magnet 10 can cause the insertion rod 9 to extend out of the mounting plate 6. When the device is pushed toward the wall module, A plurality of insertion rods 9 are horizontally and movably inserted on the side wall of the first cavity 30, so some of the insertion rods 9 will pass through the screw holes on the wall module. In this process, since the insertion rods 9 that have not passed through the screw holes are in contact with the surface of the wall panel, and the wall panel is stationary while the device is moving, the insertion rods 9 in contact with the wall panel will be pushed, and the pushed insertion rods 9 will enter the first cavity 30. When the insertion rods 9 entering the first cavity 30 come into contact with the partition 7, the insertion rods 9 will push the partition 7 to move in the first cavity 30. During the movement of the partition 7, the first spring 8 is squeezed, and the pressure in the cavity formed between the left side wall of the partition 7 and the first cavity 30 increases. At this time, the device continues to be pushed, and the pressure in the cavity continues to increase. When the first spring 8 is squeezed to the maximum, the insertion rods 9 passing through the screw holes The rod 9 which has been extended out of the surface of the wall panel and squeezed by the wall panel completely enters the mounting plate 6. At this time, the switch 18 of the warning light 17 is squeezed by the partition 7, so that the warning light 17 lights up, reminding the staff that the rod 9 is in place and can move the wall panel. At the same time, since only a part of the rod 9 will pass through the screw hole, the remaining rods 9 will be attached to the wall panel and pushed by the wall panel. When the pushed rod 9 contacts the partition 7, the partition 7 is pushed to move along the first cavity 30. During the movement of the partition 7, the pressure in the space formed between the left side wall of the partition 7 and the first cavity 30 increases and is in a high-pressure state. The push rod 22 contacts the baffle 25 which is in a vertical state in the initial state. At this time, the partition 7 continues to move, and the push rod 22 will push the baffle 25 around the first cavity 30. The second support rod 24 rotates, and at the moment the baffle 25 rotates, the opening of the conduit 23 is exposed. Since the conduit 23 connects the space and the second cavity 31, the pressure in the second cavity 31 increases. Since the capillary 13 connects the second cavity 31 and the third cavity 32, the pressure in the third cavity 32 also increases. Since the third cavity 32 is in a high-pressure state, the block 11 tends to move outward from the insertion rod 9, thus triggering the block 11 to extend. Therefore, the cavity formed between the left side wall of the partition 7 and the first cavity 30 begins to release pressure into the third cavity 32. Since the third cavity 32 and the second cavity 31 are connected by the capillary 13, when the pressure in the third cavity 32 increases, the pressure in the second cavity 31 also increases accordingly.When the pressure in the second cavity 31 increases, the block 11 pulled by the second spring 12 in the initial state will tend to extend out of the surface of the plug rod 9. Therefore, the block 11 on the plug rod 9 passing through the screw hole can extend out of the plug rod 9 surface, and the second spring 12 is stretched, which plays a role in fixing the wallboard and the mounting plate 6 together, and can prevent the wallboard from falling off during transportation. The block 11 on the plug rod 9 pushed by the wallboard and retracted into the mounting plate 6 can only fit tightly with the mounting plate 6 because the surface of the plug rod 9 contacts the mounting plate 6.

[0054] When the device passes through a road section with debris such as pebbles on the ground, the device will produce bumps. At this time, since the third spring 21 connected to the fixing rod 20 is installed on the top wall and the bottom wall of the fourth cavity 33, and the fixing rod 20 and the telescopic rod 4 are fixedly connected, when the base 1 drives the telescopic rod 4 to bump, the third spring 21 can convert the kinetic energy of the device during the bumping process into elastic potential energy, thereby reducing the bump amplitude, and preventing the insertion rod 9 from colliding with the screw hole due to the bump and causing the screw hole to deform. In addition, by movably embedding a steel ball 29 at the top of the fixing rod 20, the sliding friction between the fixing rod 20 and the fixing block 19 can be converted into rolling friction, thereby reducing the friction force. When the device is pushed on a bumpy road, it plays a role in making the fixing rod 20 move up and down in the fourth cavity 33 smoother.

[0055] When the wall panel is transported to the designated position, since the air bag 1505 is filled with gas in the initial state, the pressure plate 1503 is pushed upward, so that the pressure plate 1503 moves to the top of the guide rod 1502. When the wall module is moved to the designated position, the insertion rod 9 needs to be disengaged from the screw hole on the wall. At this time, the staff steps on the pressure plate 1503 downward, so that the pressure plate 1503 squeezes the air bag 1505 during the process of moving down along the guide rod 1502. During this process, the fourth spring 1504 is compressed, and at the same time, the gas in the air bag 1505 flows into the device slot through the air pipe 16. A large amount of gas enters the device slot, causing the pressure in the device slot to increase, thereby causing the push plate 14 to move in the device slot, thereby pushing the wall panel. Since the force is mutual, when the wall panel is subjected to a thrust, the push plate 14 will be subjected to a reaction force. At this time, since the device slot is in a high pressure state and the push plate 14 can slide in the device slot, the reaction force will act on the device. On the mounting plate 6, since the base 1 is provided with a rolling tire 302, the rolling friction between the tire 302 and the ground is small. Therefore, the mounting plate 6 subjected to the reaction force will drive the device to move in the direction away from the wall. At this time, the edge of the screw hole will be squeezed with the block 11. Since the stretched second spring 12 has a tendency to recover, the block 11 will retract into the insertion rod 9 during the process of mutual squeezing between the block 11 and the edge of the screw hole. After the block 11 retracts the insertion rod 9, the push plate 14 pushes the wall panel under the action of the reaction force, and the device will move away from the wall panel, thereby quickly making the wall panel out of contact with the insertion rod 9. When the insertion rod 9 is out of the socket, the staff no longer steps on the pressure plate 1503. At this time, the squeezed fourth spring 1504 has a tendency to recover and pushes the pressure plate 1503 upward, so that the pressure plate 1503 drives the air bag 1505 to extend, thereby preparing for stepping on the pressure plate 1503 again.

[0056] When the device is pushed, the tire 302 drives the rotating shaft 301 to rotate, and the impact rod 28 vertically installed on the rotating shaft 301 also rotates accordingly. During the rotation of the impact rod 28, it will hit the piezoelectric ceramic 27 installed on the bottom wall of the base 1. The impacted piezoelectric ceramic 27 generates electrical energy, which is then transmitted to the battery 26 connected in series with it to charge the battery 26, thereby reducing the amount of electricity charged by the outside world for the battery 26, thereby saving resources.
