Description

Technical Field

[0001] The present invention relates to the technical field of scarifying devices, and particularly to a concrete scarifying device. Background Art

[0002] A concrete scarifying device is a professional machine used for concrete surface treatment. It mainly removes the floating slurry and loose layer on the concrete surface through high-frequency impact or rotary cutters to form a rough surface, enhancing the bonding force between new and old concrete. It is commonly used in concrete structure repair, reinforcement, and interface treatment before secondary pouring, such as bridge expansion joint construction, tunnel lining repair, airport runway reconstruction and expansion projects. When in use, it is necessary to pay attention to wearing protective equipment and keeping the working surface ventilated to ensure construction safety.

[0003] In the prior art, a patent document with the publication number CN217454483U appears. This patent document discloses a concrete scarifying device, including a device main body. On the left and right sides of the lower surface of the device main body, scarifying heads are provided. On the right side of the device main body, a support mechanism is installed. The support mechanism includes a mounting block. On the right side of the mounting block, a sleeve is installed. In the middle of the upper surface of the sleeve, a support column is inserted. At the bottom end of the support column, a tray is installed. At the bottom of the outer surface of the sleeve, a positioning bolt is passed through. In this concrete scarifying device, by setting a buffer spring, the buffer spring can absorb the vibration force generated by the operation of the air compressor, reducing the impact of the vibration force on the scarifying device. By setting a hinge seat and a hinge rod, the operator can increase the scarifying range of the air compressor by rotating the hinge rod, saving manpower, improving work efficiency, and enhancing the practicability of the scarifying device.

[0004] The above and the prior art have the following defects: During the process of using a scarifying device to scarify concrete, a large amount of dust will be generated around the construction point. After these dusts spread into the air, they will pollute the surrounding environment, thus affecting the normal construction of the staff.

[0005] Therefore, a concrete scarifying device is proposed. Summary of the Invention

[0006] The purpose of the present invention is to solve the defect that during the process of using a scarifying device to scarify concrete, a large amount of dust will be generated around the construction point, and after these dusts spread into the air, they will pollute the surrounding environment, and to propose a concrete scarifying device.

[0007] To achieve the above purpose, the present invention adopts the following technical solution: A concrete scarifying device, including a bracket, on the surface of the bracket, a power box is fixedly assembled. At the output end of the power box, a plurality of scarifying heads are fixedly assembled. It further includes:

[0008] An air dust removal structure is provided on the surface of the power box for treating dust. The dust removal structure includes an air extraction ring fixedly installed on the lower surface of the power box and a water tank for storing water to adsorb dust.

[0009] A sewage discharge structure is provided on the inner wall of the water tank for facilitating the discharge of sludge. The sewage discharge structure includes a rotating rod rotatably installed on the inner wall of the water tank, a screw blade for accelerating the flow of sludge, and a belt for power transmission.

[0010] An adjustment structure is provided on the outer wall of the water tank for adjusting the tightness of the belt. The adjustment structure includes a U-shaped plate fixedly installed on the outer wall of the water tank and a tensioning wheel for pressing the belt.

[0011] The effects achieved by the above components are as follows: By setting up the dust removal structure, when the scarifying device is used to scarify concrete, the dusty air will be discharged into the water in the water tank. When the dusty air contacts the water, the water will adsorb the dust, thereby purifying the air and avoiding the situation that the surrounding air is polluted by dust and affects the normal work of the staff. By setting up the sewage discharge structure, when it is necessary to discharge the sludge, the screw blade can convey the sludge deposited at the bottom of the water tank outwards, thus facilitating the complete discharge of the sludge. By setting up the adjustment structure, during the operation of the belt, the tensioning wheel can press the belt to make the belt taut, or move in the opposite direction to reduce the pressure on the belt, avoiding the situation that the belt is overly tightened and easily broken, and thus ensuring the normal operation of the belt.

[0012] Preferably, the water tank is fixedly installed on the side wall of the power box. An air pump is fixedly assembled on the side wall of the power box. The intake end of the air pump is fixedly communicated with the air extraction ring. The exhaust end of the air pump is fixedly communicated with an exhaust pipe. The exhaust pipe is fixedly connected to the water tank. A connecting frame slidably penetrates through the water tank. A hole plate is fixedly assembled at the lower end of the connecting frame. Both the water tank and the exhaust pipe are slidably connected to the hole plate. The drainage end of the water tank is threadedly connected with a sealing cover. An extension pipe is fixedly communicated with the upper surface of the water tank.

[0013] The effects achieved by the above components are as follows: When it is necessary to treat the dust, turn on the air pump. The intake end of the air pump starts to extract air. At this time, the air extraction ring will suck the dusty air around the scarifying head. The dusty air will be conveyed by the air pump into the exhaust pipe, and then the dusty air will be discharged into the water in the water tank. When the dusty air contacts the water, the water will adsorb the dust, thereby purifying the air. The purified air will be discharged through the extension pipe.

[0014] Preferably, a fixing plate is fixedly assembled on the upper surface of the water tank. A first motor is fixedly assembled on the surface of the fixing plate. The output end of the first motor is fixedly assembled with a rotating shaft, which is rotatably connected to the fixing plate. A cam is fixedly assembled on the circumferential surface of the rotating shaft. A rotating block is rotatably connected to the connecting frame at a position relative to the cam. A first spring is fixedly assembled on the surface of the connecting frame, and one end of the first spring is fixedly connected to the water tank.

[0015] The effects achieved by the above components are as follows: During the process of treating dusty air, when the first motor is turned on, the rotation of the output end of the first motor will drive the rotating shaft to rotate, and the rotating shaft will drive the cam to rotate. The rotation of the cam will first squeeze the rotating block, and the rotating block will drive the connecting frame to slide inside the water tank. The sliding of the connecting frame will compress the first spring and drive the orifice plate to slide along the inner wall of the water tank. The sliding of the orifice plate will contact the bubbles in the water, and the orifice plate will break the bubbles, so that the dust in the bubbles can fully contact the water and be adsorbed, improving the air purification efficiency. When the cam continues to rotate, it will be separated from the rotating block. At this time, the first spring will stretch, and the connecting frame will slide upward by the tension of the first spring to reset the orifice plate, facilitating the continued driving of the orifice plate to move downward.

[0016] Preferably, a rubber ring is fixedly sleeved on the surface of the cam.

[0017] The effects achieved by the above components are as follows: During the operation of the cam, the rubber ring can reduce the collision force between the cam and the rotating block, thereby extending the service life of the cam and the rotating block.

[0018] Preferably, a plurality of square plates are fixedly assembled on the circumferential surface of the sealing cover.

[0019] The effects achieved by the above components are as follows: The square plates can increase the friction force of the arc surface of the sealing cover, thereby facilitating operation.

[0020] Preferably, the auger blades are fixedly installed on the circumferential surface of the rotating rod, and the auger blades abut against the inner wall of the water tank. One end of the rotating rod is fixedly assembled with a first runner. A second runner is rotatably connected to the outer wall of the water tank. A belt is sleeved on the circumferential surfaces of the first runner and the second runner. A first electric push rod is fixedly assembled on the side wall of the fixing plate. The output end of the first electric push rod passes through the fixing plate and is fixedly assembled with an adapter plate. A transmission wheel is rotatably connected to the surface of the adapter plate. A driving wheel is fixedly assembled on the circumferential surface of the rotating rod. Chamfers are provided on the surfaces of the transmission wheel, the driving wheel, and the second runner.

[0021] The effects achieved by the above components are as follows: During the process of treating dust, control the output end of the first electric push rod to contract. As the connecting plate moves with the first electric push rod, the driving wheel will be disengaged from the driven wheel, thus avoiding the situation where the pressure of the sludge on the sealing cover is too large due to the rotation of the auger blade during the dust treatment process and damaging the sealing cover. When it is necessary to discharge the sludge, control the output end of the first electric push rod to extend, so that the inclined surface of the driving wheel abuts against the inclined surfaces of the driven wheel and the second rotating wheel. When the rotating shaft rotates, the driven wheel will drive the driving wheel to rotate, the driving wheel will drive the second rotating wheel to rotate, the belt will drive the first rotating wheel to rotate by means of the rotation of the second rotating wheel, the first rotating wheel will drive the rotating rod to rotate, and the rotating rod will drive the auger blade to rotate along the inner wall of the water tank. The auger blade can convey the sludge deposited at the bottom of the water tank outward, thus facilitating the complete discharge of the sludge.

[0022] Preferably, a guiding rod is slidably penetrated through the fixed plate, and the guiding rod is fixedly connected with the connecting plate.

[0023] The effects achieved by the above components are as follows: During the process of the connecting plate driving the driving wheel to move, the connecting plate will drive the guiding rod to slide in the fixed plate, and the guiding rod can limit the moving path of the connecting plate.

[0024] Preferably, a second electric push rod is fixedly assembled on the surface of the U-shaped plate. The output end of the second electric push rod passes through the U-shaped plate and is fixedly assembled with a hollow tube. The hollow tube is slidably penetrated through the U-shaped plate. A sliding rod is slidably connected to the inner wall of the hollow tube. One end of the sliding rod is fixedly assembled with an L-shaped plate, and the L-shaped plate is rotatably connected with the tensioning wheel.

[0025] The effects achieved by the above components are as follows: When it is necessary to adjust the tightness of the belt, control the output end of the second electric push rod to extend, and the pressure of the tensioning wheel on the belt will increase, so as to be able to tension the overly loose belt. When the output end of the second electric push rod contracts, the pressure on the belt can be reduced, avoiding the situation where the belt is overly tightened and easily broken. Therefore, by adjusting the telescopic length of the second electric push rod, the normal operation of the belt can be ensured.

[0026] Preferably, the sliding rod has a regular hexagonal prism structure.

[0027] The effects achieved by the above components are as follows: The sliding rod with a regular hexagonal prism structure can limit the moving path of the L-shaped plate, thus ensuring the normal contact between the tensioning wheel and the belt.

[0028] Preferably, one end of the sliding rod is fixedly assembled with a second spring, and the second spring is fixedly connected with the hollow tube.

[0029] The effects achieved by the above components are as follows: When the belt shows slight slack, the second spring will squeeze the sliding rod by means of its own elastic force, the sliding rod will push the L-shaped plate, and the L-shaped plate will make the tensioning wheel squeeze the belt, thus automatically compensating for the slack belt.

[0030] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0031] 1. In the present invention, by setting a dust removal structure, when the concrete is roughened by the roughening device, the dust-laden air will be discharged into the water in the water tank. When the dust-laden air contacts the water, the water will adsorb the dust, thereby purifying the air and avoiding the situation that the dust pollution affects the normal work of the staff by polluting the surrounding air.

[0032] 2. In the present invention, by setting a sewage discharge structure, when it is necessary to discharge the sludge, the auger blade can convey the sludge deposited at the bottom of the water tank outwards, so as to facilitate the complete discharge of the sludge.

[0033] 3. In the present invention, by setting an adjusting structure, during the operation of the belt, the tensioning wheel can squeeze the belt to make the belt taut, or move in the reverse direction to reduce the pressure on the belt, avoiding the situation that the belt is overly tightened and easily broken, and thus ensuring the normal operation of the belt.

[0044] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0045] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0046] Such as Figures 1-9As shown in the figure, the present invention provides a concrete roughening device, which includes a bracket 1. A power box 2 is fixedly assembled on the surface of the bracket 1. A number of roughening heads 3 are fixedly assembled at the output end of the power box 2. The device further includes: a dust removal structure 4 arranged on the surface of the power box 2 for treating dust. The dust removal structure 4 includes an air extraction ring 401 fixedly installed on the lower surface of the power box 2 and a water tank 402 for storing water to adsorb dust; a sewage discharge structure 5 arranged on the inner wall of the water tank 402 for facilitating the discharge of sludge. The sewage discharge structure 5 includes a rotating rod 501 rotatably installed on the inner wall of the water tank 402, a screw blade 502 for accelerating the flow of sludge, and a belt 505 for power transmission; an adjustment structure 6 arranged on the outer wall of the water tank 402 for adjusting the tightness of the belt 505. The adjustment structure 6 includes a U-shaped plate 61 fixedly installed on the outer wall of the water tank 402 and a tension pulley 66 for pressing the belt 505. By setting the dust removal structure 4, when the roughening device is used to roughen the concrete, the dust-containing air will be discharged into the water in the water tank 402. When the dust-containing air contacts the water, the water will adsorb the dust, thereby purifying the air and avoiding the situation that the dust pollutes the surrounding air and affects the normal work of the staff. By setting the sewage discharge structure 5, when it is necessary to discharge the sludge, the screw blade 502 can convey the sludge deposited at the bottom of the water tank 402 outward, so as to facilitate the complete discharge of the sludge. By setting the adjustment structure 6, during the operation of the belt 505, the tension pulley 66 can press the belt 505 to make the belt 505 tightened, or move in the reverse direction to reduce the pressure on the belt 505, avoiding the situation that the belt 505 is overly tightened and easily broken, and thus ensuring the normal operation of the belt 505.

[0047] Preferably, the water tank 402 is fixedly installed on the side wall of the power box 2. An air pump 403 is fixedly assembled on the side wall of the power box 2. The intake end of the air pump 403 is fixedly communicated with the air extraction ring 401. The exhaust end of the air pump 403 is fixedly communicated with an exhaust pipe 404. The exhaust pipe 404 is fixedly connected to the water tank 402. A connecting frame 405 slidably penetrates through the water tank 402. A hole plate 406 is fixedly assembled at the lower end of the connecting frame 405. Both the water tank 402 and the exhaust pipe 404 are slidably connected to the hole plate 406. The drainage end of the water tank 402 is threadedly connected with a sealing cover 414. The upper surface of the water tank 402 is fixedly communicated with an extension pipe 416. When it is necessary to treat dust, the air pump 403 is turned on. The intake end of the air pump 403 starts to draw air. At this time, the air extraction ring 401 will suck the dust-containing air around the chiseling head 3. The dust-containing air will be transported by the air pump 403 into the exhaust pipe 404. Then, the dust-containing air will be discharged into the water in the water tank 402. When the dust-containing air comes into contact with the water, the water will adsorb the dust, thereby purifying the air. The purified air will be discharged through the extension pipe 416. A fixing plate 407 is fixedly assembled on the upper surface of the water tank 402. A first motor 408 is fixedly assembled on the surface of the fixing plate 407. The output end of the first motor 408 is fixedly assembled with a rotating shaft 409. The rotating shaft 409 is rotatably connected to the fixing plate 407. A cam 410 is fixedly assembled on the circumferential surface of the rotating shaft 409. A rotating block 411 is rotatably connected to the connecting frame 405 at a position relative to the cam 410. A first spring 412 is fixedly assembled on the surface of the connecting frame 405. One end of the first spring 412 is fixedly connected to the water tank 402. During the process of treating the dust-containing air, the first motor 408 is turned on. The rotation of the output end of the first motor 408 will drive the rotation of the rotating shaft 409. The rotating shaft 409 will drive the rotation of the cam 410. The rotation of the cam 410 will first squeeze the rotating block 411. The rotating block 411 will drive the connecting frame 405 to slide in the water tank 402. The sliding of the connecting frame 405 will compress the first spring 412 and drive the hole plate 406 to slide along the inner wall of the water tank 402. The sliding of the hole plate 406 will contact the bubbles in the water. The hole plate 406 will break the bubbles, so that the dust in the bubbles can fully contact the water and be adsorbed, improving the air purification efficiency. When the cam 410 continues to rotate, it will be disengaged from the rotating block 411. At this time, the first spring 412 extends, and the connecting frame 405 will slide upward by means of the tension of the first spring 412 to reset the hole plate 406, facilitating the continued driving of the hole plate 406 to move downward. A rubber ring 413 is fixedly sleeved on the surface of the cam 410. During the operation of the cam 410, the rubber ring 413 can reduce the collision force between the cam 410 and the rotating block 411, thereby extending the service life of the cam 410 and the rotating block 411. A plurality of square plates 415 are fixedly assembled on the circumferential surface of the sealing cover 414. The square plates 415 can increase the friction force of the arc surface of the sealing cover 414, thereby facilitating the operation.

[0048] The auger blade 502 is fixedly installed on the circumferential surface of the rotating rod 501. The auger blade 502 abuts against the inner wall of the water tank 402. One end of the rotating rod 501 is fixedly assembled with a first runner 503. The outer wall of the water tank 402 is rotatably connected with a second runner 504. The belt 505 is sleeved on the circumferential surfaces of the first runner 503 and the second runner 504. A first electric push rod 506 is fixedly assembled on the side wall of the fixing plate 407. The output end of the first electric push rod 506 passes through the fixing plate 407 and is fixedly assembled with an adapter plate 507. A transmission wheel 508 is rotatably connected to the surface of the adapter plate 507. A driving wheel 509 is fixedly assembled on the circumferential surface of the rotating rod 501. Inclined surfaces are provided on the surfaces of the transmission wheel 508, the driving wheel 509 and the second runner 504. During the process of treating dust, control the output end of the first electric push rod 506 to contract. The movement of the adapter plate 507 following the first electric push rod 506 will cause the transmission wheel 508 to disengage from the driving wheel 509, thereby avoiding the situation that the rotation of the auger blade 502 during the process of treating dust causes excessive pressure of the sludge on the sealing cover 414 and damages the sealing cover 414. When it is necessary to discharge the sludge, control the output end of the first electric push rod 506 to extend, so that the inclined surface of the transmission wheel 508 abuts against the inclined surfaces of the driving wheel 509 and the second runner 504. When the rotating shaft 409 rotates, the driving wheel 509 will drive the transmission wheel 508 to rotate. The transmission wheel 508 will drive the second runner 504 to rotate. The belt 505 will drive the first runner 503 to rotate by means of the rotation of the second runner 504. The first runner 503 will drive the rotating rod 501 to rotate. The rotating rod 501 will drive the auger blade 502 to rotate along the inner wall of the water tank 402. The auger blade 502 can convey the sludge deposited at the bottom of the water tank 402 outward, so as to facilitate the complete discharge of the sludge. A guiding rod 510 is slidably penetrated through the fixing plate 407. The guiding rod 510 is fixedly connected with the adapter plate 507. During the process of the adapter plate 507 driving the transmission wheel 508 to move, the adapter plate 507 will drive the guiding rod 510 to slide inside the fixing plate 407. The guiding rod 510 can limit the movement path of the adapter plate 507.

[0049] A second electric push rod 62 is fixedly assembled on the surface of the U-shaped plate 61. The output end of the second electric push rod 62 passes through the U-shaped plate 61 and is fixedly assembled with a hollow tube 63. The hollow tube 63 slidably penetrates through the U-shaped plate 61. A sliding rod 64 is slidably connected to the inner wall of the hollow tube 63. One end of the sliding rod 64 is fixedly assembled with an L-shaped plate 65. The L-shaped plate 65 is rotatably connected to the tension pulley 66. When it is necessary to adjust the tightness of the belt 505, the output end of the second electric push rod 62 is controlled to extend, and the pressure of the tension pulley 66 on the belt 505 will increase, so that the overly loose belt 505 can be tensioned. When the output end of the second electric push rod 62 contracts, the pressure on the belt 505 can be reduced, avoiding the situation that the belt 505 is overly tightened and easily broken. Therefore, by adjusting the telescopic length of the second electric push rod 62, the normal operation of the belt 505 can be ensured. The sliding rod 64 is in the shape of a regular hexagonal prism. The sliding rod 64 in the shape of a regular hexagonal prism can limit the movement path of the L-shaped plate 65, so as to ensure the normal contact between the tension pulley 66 and the belt 505. One end of the sliding rod 64 is fixedly assembled with a second spring 67. The second spring 67 is fixedly connected to the hollow tube 63. When the belt 505 is slightly loose, the second spring 67 will squeeze the sliding rod 64 by its own elastic force. The sliding rod 64 will push the L-shaped plate 65, and the L-shaped plate 65 will make the tension pulley 66 squeeze the belt 505, so as to automatically compensate for the loose belt 505.

[0050] The overall working principle is as follows: When using the scarifying device to scarify concrete, pour clean water into the water tank 402 through the extension pipe 416 to make the water level higher than the orifice plate 406, and then turn on the power box 2. The output end of the power box 2 will drive the scarifying head 3 to work and scarify the concrete. When it is necessary to treat dust, turn on the air pump 403. The intake end of the air pump 403 starts to draw in air. At this time, the air extraction ring 401 will suck the dust-containing air around the scarifying head 3. The dust-containing air will be transported by the air pump 403 into the exhaust pipe 404, and then the dust-containing air will be discharged into the water in the water tank 402. When the dust-containing air contacts the water, the water will adsorb the dust, thereby purifying the air. The purified air will be discharged through the extension pipe 416. During the process of treating the dust-containing air, turn on the first motor 408. The rotation of the output end of the first motor 408 will drive the rotation of the rotating shaft 409. The rotating shaft 409 will drive the rotation of the cam 410. The rotation of the cam 410 will first squeeze the rotating block 411. The rotating block 411 will drive the connecting frame 405 to slide in the water tank 402. The sliding of the connecting frame 405 will compress the first spring 412 and drive the orifice plate 406 to slide along the inner wall of the water tank 402. The sliding of the orifice plate 406 will contact the bubbles in the water, and the orifice plate 406 will break the bubbles, so that the dust in the bubbles can fully contact the water and be adsorbed, improving the air purification efficiency. When the cam 410 continues to rotate and is disengaged from the rotating block 411, at this time the first spring 412 extends, and the connecting frame 405 will slide upward by means of the tension of the first spring 412 to reset the orifice plate 406, facilitating the continued driving of the orifice plate 406 to move downward. During the operation of the cam 410, the rubber ring 413 can reduce the collision force between the cam 410 and the rotating block 411, thereby extending the service life of the cam 410 and the rotating block 411.

[0051] During the process of treating dust, control the output end of the first electric push rod 506 to contract. When the connecting plate 507 moves along with the first electric push rod 506, the driving wheel 508 will be disengaged from the driven wheel 509, thus avoiding the situation that the excessive pressure of the sludge on the sealing cover 414 caused by the rotation of the auger blade 502 during the process of treating dust damages the sealing cover 414. When it is necessary to discharge the sludge, rotate the sealing cover 414 by means of the square plate 415. The square plate 415 can increase the friction force on the arc surface of the sealing cover 414, thus facilitating the operation. After removing the sealing cover 414, the sewage will gradually drain out. At this time, control the output end of the first electric push rod 506 to extend, so that the inclined surface of the driving wheel 508 abuts against the inclined surfaces of the driven wheel 509 and the second runner 504. When the rotating shaft 409 rotates, the driven wheel 509 will drive the driving wheel 508 to rotate, the driving wheel 508 will drive the second runner 504 to rotate, the belt 505 will drive the first runner 503 to rotate by means of the rotation of the second runner 504, the first runner 503 will drive the rotating rod 501 to rotate, and the rotating rod 501 will drive the auger blade 502 to rotate along the inner wall of the water tank 402. The auger blade 502 can convey the sludge deposited at the bottom of the water tank 402 outwards, thus facilitating the complete discharge of the sludge. During this process, the orifice plate 406 will vibrate continuously, thus facilitating the shaking off of the sludge attached to the surface of the orifice plate 406 and reducing the pollution of the subsequently added clean water by the residual sludge. During the process of the connecting plate 507 driving the driving wheel 508 to move, the connecting plate 507 will drive the guiding rod 510 to slide along the fixed plate 407, and the guiding rod 510 can limit the moving path of the connecting plate 507.

[0052] During the operation of the belt 505, when the belt 505 is slightly slack, the second spring 67 will squeeze the sliding rod 64 by its own elastic force. The sliding rod 64 will push the L-shaped plate 65, and the L-shaped plate 65 will make the tensioning wheel 66 squeeze the belt 505, so as to automatically compensate for the slack belt 505 and make the belt 505 re-tightened to ensure that the second runner 504 can normally drive the first runner 503 to rotate. The sliding rod 64 with a regular hexagonal prism structure can limit the moving path of the L-shaped plate 65, thus ensuring the normal contact between the tensioning wheel 66 and the belt 505. When it is necessary to further adjust the tightness of the belt 505, control the output end of the second electric push rod 62 to extend, and the pressure of the tensioning wheel 66 on the belt 505 will increase, so as to be able to tension the overly slack belt 505. When the output end of the second electric push rod 62 contracts, the pressure on the belt 505 can be reduced, avoiding the situation that the belt 505 is overly tightened and easily broken. Therefore, by adjusting the telescopic length of the second electric push rod 62, the normal operation of the belt 505 can be ensured.
