Description

Technical Field

[0001] The present invention relates to the technical field of track bolt fastening, and specifically to a gantry crane robot guide rail bolt tightening structure. Background Art

[0002] A gantry crane is a bridge crane used in industrial plants. Its operating track is installed on the column girder, also known as "driver", "traveling crane", "overhead crane", etc. It is a hoisting machine that spans across the workshop for hoisting various objects. When laying the track currently, track bolts are required for fastening. However, when the crane passes through the track, the track often vibrates greatly, and the bolts are extremely likely to become loose during vibration, so the bolts need to be tightened regularly. Therefore, ensuring reliable bolt connection is an important part of track maintenance and is of great significance to the safety of the crane.

[0003] In the prior art, since most track bolts are in the outdoor environment, the maintenance operations such as loosening and tightening of track bolts mainly rely on manual use of various hydraulic wrenches or traditional electric wrenches. Because the number of track bolts is mostly large, the operations of manually loosening and tightening bolts have defects such as high labor intensity, long operation time, low work efficiency, and inability to guarantee the bolt tightening quality. It not only cannot meet the requirements of track bolt fastening, but also due to long-term manual operation, it is easy to cause the fastening of some bolts not to meet the standards or there are cases of omission or error.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. When the circular block is driven to rotate by the connecting rod, the rotation of the circular block will move due to the threaded blocks and the threaded grooves, so that the circular block can drive the first round rod and the cleaning brush to move, so that the cleaning brush can adjust the number of rotation circles of the bolt torque wrench according to the depth of the hollow part of the bolt torque wrench, so that the cleaning brush can move to a suitable depth under the rotation of the circular block, so that the device can adjust the moving depth of the cleaning brush according to the hollow depth of the bolt torque wrench, thus being more practical and convenient.

[0016] 2. When the cleaning brush, the cleaning rod, and the cleaning block scrape off impurities, the impurities will fall onto a pair of inclined plates on the square shell. Since the inclined plates are hinged to the inner wall of the square shell and connected to the square shell through the fifth spring, when the square shell vibrates during the operation of each mechanism, the inclined plates will drive the fifth spring to contract and extend, causing the inclined plates to vibrate and change their angles up and down at the same time. This helps the impurities fall into the square shell more conveniently. Moreover, due to the structure of the inclined plates, the inclined plates also have the function of blocking the impurities from moving out of the square shell. When the impurities fall into the square shell, they will fall into the collection shell through the square shell. When the impurities need to be collected, by moving the clamping block out of the clamping groove on the square shell, the fixation between the square shell and the collection shell is released. At this time, removing the collection shell can collect and recycle the impurities, making the device not only convenient for cleaning impurities but also making it more convenient to collect impurities through the structure of the inclined plates, and preventing the impurities from adhering to the inclined plates easily.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment 1:

By driving the first reduction shaft 11 to rotate through the first servo motor 9 and the first speed reducer 10, the first reduction shaft 11 drives the first synchronous pulley 13 to rotate, and the first synchronous pulley 13 drives the first synchronous belt 16 to rotate. When the first synchronous belt 16 rotates, the first synchronous belt 16 drives the horizontal moving platform 3 to move on the horizontal linear guide rail 2 through the first connecting device, so that the horizontal moving platform 3 drives the slideway plate 4, the vertical moving platform 6 and the bolt torque wrench 7 to move horizontally, and the bolt torque wrench 7 moves to the position of the track bolt. Then, the bolt torque wrench 7 is clamped on the outer surface of the track bolt through the moving member. At this time, the rotation of the bolt torque wrench 7 completes maintenance operations such as loosening and tightening the bolt. Since this device realizes automatic positioning, tightening and loosening of the bolt, replacing multiple workers, the labor cost is reduced. And because this device completes the automatic positioning, tightening and loosening of the bolt by mechanical operation, the working efficiency of this device is relatively high, and it is not easy for the bolt to have the situation of misalignment or non-compliance with the standard.

[0032] On one side of the outer wall of the slide plate 4, a second servo motor 17 is fixedly connected; at the output end of the second servo motor 17, a second speed reducer 18 is provided; at the output end of the second speed reducer 18, a second reduction shaft 19 is provided; on the outer side wall of the second reduction shaft 19, a second deep groove ball bearing 20 is arranged; at one end of the outer wall of the second reduction shaft 19, a second synchronous pulley 21 is fixedly connected; at the top ends of the outer walls of a pair of second bearing seats 8, they are both fixedly connected to the bottom end of the outer wall of the slide plate 4; between the pair of second bearing seats 8, a second driven pulley 22 is arranged, and the second driven pulley 22 and the second synchronous pulley 21 are connected by a second synchronous belt 23; the vertical moving platform 6 is connected to the second synchronous belt 23 through a second connecting device. By driving the second reduction shaft 19 to rotate through the second servo motor 17 and the second speed reducer 18, the second reduction shaft 19 drives the second synchronous pulley 21 to rotate, the second synchronous pulley 21 and the second driven pulley 22 drive the second synchronous belt 23 to rotate, and the second synchronous belt 23 drives the vertical moving platform 6 to move on the vertical linear guide 5 through the second connecting device, the vertical moving platform 6 drives the bolt torque wrench 7 to move, the bolt torque wrench 7 is clamped on the outer surface of the track bolt, and the rotation of the bolt torque wrench 7 completes maintenance operations such as loosening and tightening of the track bolt. In this device, through the mutual cooperation of the vertical moving platform 6 and the horizontal moving platform 3, the movement of the bolt torque wrench 7 and the positioning of the track bolt are completed, thereby realizing operations such as automatic positioning, tightening, and loosening of the bolt, making this device not only more intelligent, convenient, and fast, but also improving the working efficiency and reducing the error rate compared with manual operation.

[0033] One side of the outer wall of the slide plate 4 is rotatably connected with a rotating rod 24; a first gear 25 is fixedly connected to the outer side wall of the rotating rod 24; a first rack 26 is fixedly connected to one side of the outer wall of the vertical moving platform 6, and the first rack 26 is L-shaped; the first rack 26 meshes with the first gear 25; one end of the outer wall of the rotating rod 24 is fixedly connected with a second bevel gear 27; one side of the outer wall of the slide plate 4 is rotatably connected with a first rotating rod 28 through a second square plate; a third bevel gear 29 is fixedly connected to one end of the outer wall of the first rotating rod 28, and the third bevel gear 29 meshes with the second bevel gear 27; a fourth gear 30 is fixedly connected to the other end of the outer wall of the first rotating rod 28; a square plate 31 is fixedly connected to one side of the outer wall of the slide plate 4; a placing plate 32 is slidably connected to the top end of the outer wall of the square plate 31; a fourth rack 33 is fixedly connected to one side of the outer wall of the placing plate 32, and the fourth rack 33 meshes with the fourth gear 30; a circular shell 34 is fixedly connected to the inner side wall of the placing plate 32; a circular block 35 is arranged on the inner side wall of the circular shell 34; a first circular shell 36 is fixedly connected to one end of the outer wall of the circular block 35; a first circular rod 37 is fixedly connected to one side of the inner wall of the first circular shell 36 through a first spring, and the outer side wall of the first circular rod 37 is slidably connected to the inner side wall of the first circular shell 36; a group of cleaning brushes 38 are fixedly connected to the outer side wall of the first circular rod 37, and the cleaning brushes 38 are matched with the bolt torque wrench 7;A frustum-shaped block 39 is fixedly connected to the end of the outer wall of the bolt torque wrench 7, and the frustum-shaped block 39 matches the first round rod 37. After the bolt torque wrench 7 completes operations such as tightening and loosening the track bolts, the second servo motor 17 will cause the vertical moving table 6 to drive the bolt torque wrench 7 to move backward, thus disengaging the fixation of the track bolts, facilitating the positioning and tightening of the next track bolt. When the vertical moving table 6 moves, the vertical moving table 6 will drive the first rack 26 to move. Since the first gear 25 is fixedly connected to the outer wall of the rotating rod 24 and the first rack 26 meshes with the first gear 25, the movement of the first rack 26 will drive the first gear 25 to rotate, causing the first gear 25 to drive the rotating rod 24 to rotate, and the rotating rod 24 to drive the second bevel gear 27 to rotate. Since the third bevel gear 29 is fixedly connected to one end of the outer wall of the first rotating rod 28, and the third bevel gear 29 meshes with the second bevel gear 27, the rotation of the second bevel gear 27 drives the first rotating rod 28 to rotate through the third bevel gear 29, causing the first rotating rod 28 to drive the fourth gear 30 to rotate. Since the fourth rack 33 meshes with the fourth gear 30, the rotation of the fourth gear 30 drives the fourth rack 33 to move, causing the fourth rack 33 to drive the placement plate 32 to move. When the vertical moving spray head moves to a certain position, the placement plate 32 will drive the circular shell 34 to move in front of the bolt torque wrench 7, causing the first round rod 37 and the cleaning brush 38 to enter the part of the bolt torque wrench 7 that twists the track bolts. Since the frustum-shaped block 39 is fixedly connected to the end of the outer wall of the bolt torque wrench 7, and the frustum-shaped block 39 matches the first round rod 37 and the first round rod 37 is connected to the first circular shell 36 through the first spring, the first round rod 37 has elasticity, so that the first round rod 37 will contract when it encounters the frustum-shaped block 39 and will spring into the hollow part of the bolt torque wrench 7 when it moves to the hollow part of the bolt torque wrench 7. At this time, the bolt torque wrench 7 rotates while the cleaning brush 38 remains stationary, enabling the cleaning brush 38 to clean the hollow part of the bolt torque wrench 7, removing impurities or waste chips, etc., thus ensuring the internal environment of the bolt torque wrench 7, so that the bolt torque wrench 7 is not easily unable to maintain the track bolts due to being piled up with impurities or waste chips, etc. Moreover, the inside of the bolt torque wrench 7 is cleaned, making the bolt torque wrench 7 not easily malfunction or have problems during long-term use, thus ensuring the normal operation of the device and reducing the error probability of the bolt torque wrench 7.;

[0034] One end of the outer wall of the circular shell 34 is rotatably connected to a connecting rod 40, and one end of the outer wall of the connecting rod 40 penetrates through one side of the outer wall of the circular shell 34 and is located inside the circular shell 34; one end of the outer wall of the connecting rod 40 located inside the circular shell 34 is fixedly connected to one end of the outer wall of the circular block 35; the top end of the outer wall of the placing plate 32 is rotatably connected to a linkage rod 41 through a third-party plate; sprockets 42 are fixedly connected to one ends of the outer walls of the linkage rod 41 and the connecting rod 40, and a pair of sprockets 42 are connected by a chain 43; a fifth gear 44 is fixedly connected to the other end of the outer wall of the linkage rod 41; a sixth gear 45 is fixedly connected to the outer side wall of the bolt torque wrench 7, and the sixth gear 45 is matched with the fifth gear 44. When the bolt torque wrench 7 rotates to enable the cleaning brush 38 to clean the inside of the bolt torque wrench 7, when the bolt torque wrench 7 and the placing plate 32 are in appropriate positions, the bolt torque wrench 7 rotates to adjust the sixth gear 45 on its outer side wall, so that when the placing plate 32 drives the cleaning brush 38 to reach an appropriate position, the fifth gear 44 on the linkage rod 41 on the placing plate 32 will contact the sixth gear 45, thereby completing meshing. At this time, the rotation of the bolt torque wrench 7 will drive the fifth gear 44 to rotate through the sixth gear 45, so that the fifth gear 44 drives the linkage rod 41 to rotate. Since sprockets 42 are fixedly connected to one ends of the outer walls of the linkage rod 41 and the connecting rod 40, and a pair of sprockets 42 are connected by a chain 43, the rotation of the linkage rod 41 drives the connecting rod 40 to rotate through the sprockets 42 and the chain 43, so that the connecting rod 40 drives the circular block 35 to rotate, and the circular block 35 drives the cleaning brush 38 to rotate. Because of the overall structure of the device, the rotation directions of the bolt torque wrench 7 and the cleaning brush 38 are opposite, thereby improving the cleaning efficiency and effect of the cleaning brush 38, making the cleaning of the cleaning brush 38 more thorough, and further improving the continuous working efficiency of the device.

[0035] The connecting rod 40 is a telescopic rod, and the end of the connecting rod 40 fixedly connected to the circular block 35 is the telescopic end; a set of threaded blocks 52 are fixedly connected to the outer side wall of the circular block 35; a set of threaded blocks 52 are fixedly connected to the outer side wall of the circular block 35. By the connecting rod 40 being a telescopic rod, a set of threaded blocks 52 being fixedly connected to the outer side wall of the circular block 35, and a set of threaded blocks 52 being fixedly connected to the outer side wall of the circular block 35, when the connecting rod 40 drives the circular block 35 to rotate, the rotation of the circular block 35 will move due to the threaded blocks 52 and the threaded grooves 53, so that the circular block 35 can drive the first round rod 37 and the cleaning brush 38 to move, so that the cleaning brush 38 can adjust the number of rotation turns of the bolt torque wrench 7 according to the depth of the hollow part of the bolt torque wrench 7, so that the cleaning brush 38 can move to a suitable depth under the rotation of the circular block 35, so that the device can adjust the moving depth of the cleaning brush 38 according to the hollow depth of the bolt torque wrench 7, thus being more practical and convenient. Moreover, the cleaning brush 38 can achieve the effect of reciprocating motion through the forward and reverse rotation of the bolt torque wrench 7, so that the cleaning brush 38 can take out the impurities in the bolt torque wrench 7 during reciprocating motion, thus further improving the cleaning effect of the device. And through the reciprocating motion of the cleaning brush 38, the cleaning brush 38 can move into the interior of the circular shell 34 when not in use, so that the cleaning brush 38 is not easily adhered to dust when not in use, thus ensuring the cleanliness of the cleaning brush 38.

[0036] The bottom end of the outer wall of the slide plate 4 is fixedly connected with an auxiliary plate 46 through a pair of connecting blocks; a pair of vertical plates 47 are slidably connected to the outer side wall of the auxiliary plate 46, and the pair of vertical plates 47 are symmetric about the center line of the auxiliary plate 46; on the opposite sides of the outer walls of the pair of vertical plates 47, clamping blocks 48 are fixedly connected through second springs, and the pair of clamping blocks 48 are matched with the vertical moving platform 6; on one side of the outer wall of the connecting block, a bidirectional threaded rod 49 is rotatably connected, and both ends of the outer wall of the bidirectional threaded rod 49 penetrate through the pair of connecting blocks and the vertical plates 47 respectively; the bidirectional threaded rod 49 is threadedly connected with the pair of vertical plates 47; one end of the outer wall of the bidirectional threaded rod 49 is fixedly connected with a seventh gear 50; an eighth gear 51 is fixedly connected to the outer side wall of the rotating rod 24, and the eighth gear 51 meshes with the seventh gear 50. When the vertical moving plate moves backward to drive the first gear 25 and the rotating rod 24 to rotate through the first rack 26, since the eighth gear 51 is fixedly connected to the outer side wall of the rotating rod 24 and the eighth gear 51 meshes with the seventh gear 50, the rotation of the rotating rod 24 drives the seventh gear 50 to rotate through the eighth gear 51, the seventh gear 50 drives the bidirectional threaded rod 49 to rotate, and the rotation of the bidirectional threaded rod 49 drives the pair of vertical plates 47 to move towards the center of the slide plate 4. When the vertical moving platform 6 moves to a suitable position, at this time, the pair of vertical plates 47 will drive a pair of clamping plates to clamp the vertical moving platform 6, so that the vertical moving platform 6 is clamped and fixed. Thus, when the device operates, the vertical moving platform 6 is not easily affected by external forces, resulting in misalignment of the various parts in the device, thereby ensuring the normal operation of the device. And when the device is transported, by clamping and fixing the vertical moving platform 6, the vertical moving platform 6 is not easily driven to move the bolt torque wrench 7, so that the device is more stable and safe during transportation, and the probability of the bolt torque wrench 7 colliding during transportation is reduced.

[0037] A pair of arc-shaped grooves 54 are formed in the outer wall of the circular shell 34; cleaning blocks 55 are fixedly connected to the bottom ends of the inner walls of the pair of arc-shaped grooves 54; a set of cleaning rods 56 are fixedly connected to the top ends of the outer walls of the pair of cleaning blocks 55, and the two sets of cleaning rods 56 are both matched with the cleaning brush 38; the cleaning block 55 is in the shape of a right trapezoid, and the top end of the outer wall of the cleaning block 55 is an inclined surface. When the cleaning of the bolt torque wrench 7 by the cleaning brush 38 is completed, at this time, the cleaning brush 38 retracts into the circular shell 34 under the rotation of the bolt torque wrench 7. When the cleaning brush 38 moves to the position of the arc-shaped groove 54 in the circular shell 34, the cleaning brush 38 will move into a set of cleaning rods 56 on the cleaning block 55 under rotation. When the cleaning brush 38 continues to rotate, the cleaning brush 38 will be divided into multiple parts by the cleaning rods 56. When the cleaning brush 38 encounters the cleaning block 55, the cleaning brush 38 will rotate and slowly retract into the circular shell 34. At this time, because the cleaning brush 38 is located between a set of cleaning rods 56 and the cleaning brush 38 contacts the cleaning block 55, when the cleaning brush 38 retracts into the circular shell 34, a set of cleaning rods 56 cooperate with the cleaning block 55 to scrape off the impurities adhering to the cleaning brush 38. And because there are a pair of cleaning blocks 55, when the first round rod 37 drives the cleaning brush 38 to rotate forward and backward, the cleaning blocks 55 cooperate with the cleaning rods 56 to clean the cleaning brush 38, so as to ensure the cleanliness of the cleaning brush 38. Therefore, when the cleaning brush 38 cleans the bolt torque wrench 7, it is not easy to cause the situation that the inside of the bolt torque wrench 7 cannot be cleaned due to too much impurities adhering to the cleaning brush 38. Thus, through the cleaning of the cleaning brush 38 by this device, the bolt torque wrench 7 can be cleaned more thoroughly, and the cleaning efficiency and cleaning effect of this device are not easy to decrease.

[0038] Embodiment 2:

[0039] Please refer to Figure 6 and Figure 10As shown in the figure, on one side of the outer wall of the placement plate 32, a square shell 57 is fixedly connected, and both the top and bottom of the outer wall of the square shell 57 are open; on both opposite sides of the outer wall of the square shell 57, clamping grooves 58 are provided; on the inner side walls of a pair of clamping grooves 58, clamping blocks 59 are slidably placed; at the bottom ends of the outer walls of a pair of clamping blocks 59, a collection shell 60 is fixedly connected, and the top of the outer wall of the collection shell 60 is open, and the collection shell 60 matches the square shell 57; at the top ends of the opposite sides of the inner wall of the square shell 57, inclined plates 61 are hinged; on the opposite sides of the inner wall of the square shell 57, fifth springs 62 are fixedly connected, and one ends of the outer walls of a pair of fifth springs 62 are respectively fixedly connected to the top ends of the outer walls of a pair of inclined plates 61; the square shell 57 matches a pair of cleaning blocks 55. When impurities are scraped off by the cleaning rod 56 and the cleaning block 55 on the cleaning brush 38, the impurities will fall onto a pair of inclined plates 61 on the square shell 57. Since the inclined plates 61 are hinged to the inner wall of the square shell 57 and the inclined plates 61 are connected by the fifth springs 62, when the square shell 57 vibrates during the operation of each mechanism, the inclined plates 61 will drive the fifth springs 62 to contract and extend, causing the inclined plates 61 to vibrate and change their angles up and down at the same time, thereby assisting the impurities to fall into the square shell 57, making it more convenient for the impurities to fall into the square shell 57. And through the structure of the inclined plates 61, the inclined plates 61 also have the function of blocking the impurities from moving out of the square shell 57. When the impurities fall into the square shell 57, they will fall into the collection shell 60 through the square shell 57. When the impurities need to be collected, by removing the clamping blocks 59 from the clamping grooves 58 on the square shell 57, the square shell 57 and the collection shell 60 are released from fixation. At this time, by removing the collection shell 60, the impurities can be collected and recycled. This device not only facilitates the cleaning of impurities, but also makes it more convenient for the impurities to be collected through the structure of the inclined plates 61, and makes the impurities not easily adhere to the inclined plates 61.

[0040] When the present invention is in use, the first servo motor 9 and the first speed reducer 10 drive the first reduction shaft 11 to rotate, so that the first reduction shaft 11 drives the first synchronous pulley 13 to rotate, and the first synchronous pulley 13 drives the first synchronous belt 16 to rotate. When the first synchronous belt 16 rotates, the first synchronous belt 16 drives the horizontal moving platform 3 to move on the horizontal linear guide rail 2 through the first connecting device, so that the horizontal moving platform 3 drives the slide plate 4, the vertical moving platform 6 and the bolt torque wrench 7 to move horizontally, and the bolt torque wrench 7 moves to the position of the track bolt. Then, the bolt torque wrench 7 is clamped on the outer surface of the track bolt through the moving part. At this time, the rotation of the bolt torque wrench 7 completes maintenance operations such as loosening and tightening the bolt. Since this device realizes automatic positioning, tightening and loosening of the bolt, replacing multiple workers, the labor cost is reduced. And because this device completes the automatic positioning, tightening and loosening of the bolt by mechanical operation, the working efficiency of this device is relatively high, and it is not easy for the bolt to have the situation of omission or non-compliance with the standard. And the second servo motor 17 and the second speed reducer 18 drive the second reduction shaft 19 to rotate, so that the second reduction shaft 19 drives the second synchronous pulley 21 to rotate, and the second synchronous pulley 21 and the second driven pulley 22 drive the second synchronous belt 23 to rotate. The second synchronous belt 23 drives the vertical moving platform 6 to move on the vertical linear guide rail 5 through the second connecting device, so that the vertical moving platform 6 drives the bolt torque wrench 7 to move, and the bolt torque wrench 7 is clamped on the outer surface of the track bolt, and the rotation of the bolt torque wrench 7 completes maintenance operations such as loosening and tightening the track bolt. In this device, the movement of the bolt torque wrench 7 and the positioning of the track bolt are completed through the mutual cooperation of the vertical moving platform 6 and the horizontal moving platform 3, so as to realize operations such as automatic positioning, tightening and loosening of the bolt, making this device not only more intelligent, convenient and fast, but also improving the working efficiency, and reducing the error rate compared with manual operation. And when the bolt torque wrench 7 completes operations such as tightening and loosening the track bolt, the second servo motor 17 will make the vertical moving platform 6 drive the bolt torque wrench 7 to move backward, so as to disengage from the fixation of the track bolt, thus facilitating the positioning and tightening of the next track bolt. When the vertical moving platform 6 moves, the vertical moving platform 6 will drive the first rack 26 to move. Since the first gear 25 is fixedly connected to the outer side wall of the rotating rod 24 and the first rack 26 meshes with the first gear 25, the movement of the first rack 26 will drive the first gear 25 to rotate, and the first gear 25 drives the rotating rod 24 to rotate, and the rotating rod 24 drives the second bevel gear 27 to rotate. Since the third bevel gear 29 is fixedly connected to one end of the outer wall of the first rotating rod 28, and the third bevel gear 29 meshes with the second bevel gear 27, the rotation of the second bevel gear 27 drives the first rotating rod 28 to rotate through the third bevel gear 29, and the first rotating rod 28 drives the fourth gear 30 to rotate. Since the fourth rack 33 meshes with the fourth gear 30, the rotation of the fourth gear 30 drives the fourth rack 33 to move, and the fourth rack 33 drives the placement plate 32 to move.When the vertical moving nozzle moves to a certain position, the placement plate 32 will drive the circular shell 34 to move in front of the bolt torque wrench 7, so that the first round rod 37 and the cleaning brush 38 enter the part where the bolt torque wrench 7 twists the track bolt. Since the frustum block 39 is fixedly connected to the end of the outer wall of the bolt torque wrench 7, and the frustum block 39 matches the first round rod 37 and the first round rod 37 is connected to the first round shell 36 through the first spring, the first round rod 37 has elasticity, so that when the first round rod 37 encounters the frustum block 39, it will contract, and when it moves to the hollow part of the bolt torque wrench 7, it will spring into it. At this time, the bolt torque wrench 7 rotates, while the cleaning brush 38 remains stationary, so that the cleaning brush 38 cleans the hollow part of the bolt torque wrench 7, so that impurities or waste chips are cleaned, thus ensuring the internal environment of the bolt torque wrench 7, so that the bolt torque wrench 7 is not easily unable to maintain the track bolt due to being piled up with impurities or waste chips, and the inside of the bolt torque wrench 7 is cleaned, so that the bolt torque wrench 7 is not easily faulty or problematic during long-term use, thus ensuring the normal operation of the device and reducing the error probability of the bolt torque wrench 7. And when the bolt torque wrench 7 rotates so that the cleaning brush 38 cleans the inside of the bolt torque wrench 7, when the bolt torque wrench 7 and the placement plate 32 are in the appropriate positions, the bolt torque wrench 7 rotates to adjust the sixth gear 45 on its outer wall. When the placement plate 32 drives the cleaning brush 38 to reach the appropriate position, the fifth gear 44 on the linkage rod 41 on the placement plate 32 will contact the sixth gear 45, thus completing the meshing. At this time, the rotation of the bolt torque wrench 7 will drive the fifth gear 44 to rotate through the sixth gear 45, so that the fifth gear 44 drives the linkage rod 41 to rotate. Since the outer wall ends of the linkage rod 41 and the connecting rod 40 are both fixedly connected with sprockets 42, and a pair of sprockets 42 are connected by a chain 43, the rotation of the linkage rod 41 drives the connecting rod 40 to rotate through the sprockets 42 and the chain 43, so that the connecting rod 40 drives the circular block 35 to rotate, so that the circular block 35 drives the cleaning brush 38 to rotate. Since the overall structure of the device makes the rotation directions of the bolt torque wrench 7 and the cleaning brush 38 opposite, the cleaning efficiency and effect of the cleaning brush 38 are improved, so that the cleaning brush 38 is cleaned more thoroughly, thus further improving the continuous working efficiency of the device. And since the connecting rod 40 is a telescopic rod and a group of threaded blocks 52 are fixedly connected to the outer wall of the circular block 35 and a group of threaded blocks 52 are fixedly connected to the outer wall of the circular block 35, when the connecting rod 40 drives the circular block 35 to rotate, the rotation of the circular block 35 will move due to the threaded blocks 52 and the threaded grooves 53, so that the circular block 35 can drive the first round rod 37 and the cleaning brush 38 to move, so that the cleaning brush 38 can adjust the number of rotation circles of the bolt torque wrench 7 according to the depth of the hollow part of the bolt torque wrench 7, so that the cleaning brush 38 can move to the appropriate depth under the rotation of the circular block 35.Thus, the device can adjust the moving depth of the cleaning brush 38 according to the hollow depth of the bolt torque wrench 7, making it more practical and convenient. Moreover, the cleaning brush 38 can achieve a reciprocating motion through the forward and reverse rotation of the bolt torque wrench 7, so that the cleaning brush 38 can take out the impurities in the bolt torque wrench 7 during the reciprocating motion, further improving the cleaning effect of the device. And because the cleaning brush 38 can reciprocate, it can move into the interior of the circular shell 34 when not in use, making it not easy to adhere to dust when not in use, thus ensuring the cleanliness of the cleaning brush 38. When the cleaning brush 38 finishes cleaning the bolt torque wrench 7, at this time, the cleaning brush 38 contracts back into the circular shell 34 under the rotation of the bolt torque wrench 7. When the cleaning brush 38 moves to the position of the arc groove 54 in the circular shell 34, the cleaning brush 38 will move into a set of cleaning rods 56 on the cleaning block 55 under rotation. When the cleaning brush 38 continues to rotate, the cleaning brush 38 will be divided into multiple parts by the cleaning rods 56. When the cleaning brush 38 encounters the cleaning block 55, the cleaning brush 38 will slowly retract into the circular shell 34 under rotation. At this time, because the cleaning brush 38 is located between a set of cleaning rods 56 and contacts the cleaning block 55, when the cleaning brush 38 retracts into the circular shell 34, the impurities adhered to the cleaning brush 38 will be scraped off by a set of cleaning rods 56 in cooperation with the cleaning block 55. And because there are a pair of cleaning blocks 55, when the first round rod 37 drives the cleaning brush 38 to rotate forward and backward, there are cleaning blocks 55 cooperating with the cleaning rods 56 to clean the cleaning brush 38, thus ensuring the cleanliness of the cleaning brush 38. When the cleaning brush 38 cleans the bolt torque wrench 7, it is not easy to cause the situation that the inside of the bolt torque wrench 7 cannot be cleaned because there are too many impurities adhered to the cleaning brush 38. Thus, through the cleaning of the cleaning brush 38, the bolt torque wrench 7 can be cleaned more thoroughly, and the cleaning efficiency and cleaning effect of the device are not easy to decrease. And when the impurities are scraped off the cleaning brush 38 by the cleaning rods 56 and the cleaning block 55, the impurities will fall onto a pair of inclined plates 61 on the square shell 57. Because the inclined plates 61 are hinged to the inner wall of the square shell 57 and the inclined plates 61 are connected by the fifth spring 62, when the square shell 57 vibrates during the operation of each mechanism, the inclined plates 61 will drive the fifth spring 62 to contract and extend, causing the inclined plates 61 to vibrate and change the angle up and down at the same time, thus assisting the impurities to fall into the square shell 57, making it more convenient for the impurities to fall into the square shell 57. And through the structure of the inclined plates 61, the inclined plates 61 also have the function of blocking the impurities from moving out of the square shell 57. When the impurities fall into the square shell 57, they will fall into the collection shell 60 through the square shell 57. When the impurities need to be collected, by removing the clamping block 59 from the clamping groove 58 on the square shell 57, the square shell 57 and the collection shell 60 are released from fixation. At this time, removing the collection shell 60 can collect and recycle the impurities, making the device not only convenient for cleaning impurities,Moreover, the structure of the inclined plate 61 makes it more convenient to collect impurities, and makes it difficult for impurities to adhere to the inclined plate 61. When the vertical moving plate moves backward to drive the first gear 25 and the rotating rod 24 to rotate through the first rack 26, since the eighth gear 51 is fixedly connected to the outer side wall of the rotating rod 24, and the eighth gear 51 meshes with the seventh gear 50, the rotation of the rotating rod 24 drives the seventh gear 50 to rotate through the eighth gear 51, the seventh gear 50 drives the bidirectional threaded rod 49 to rotate, and the rotation of the bidirectional threaded rod 49 drives a pair of vertical plates 47 to move towards the center of the slide plate 4. When the vertical moving platform 6 moves to a suitable position, at this time, a pair of vertical plates 47 will drive a pair of clamps to clamp the vertical moving platform 6, so that the vertical moving platform 6 is clamped and fixed. Thus, when the device operates, the vertical moving platform 6 is not easily affected by external forces, resulting in misalignment of the various parts in the device, thereby ensuring the normal operation of the device. Moreover, when the device is transported, by clamping and fixing the vertical moving platform 6, the vertical moving platform 6 is not easily driven to move the bolt torque wrench 7, so that the device is more stable and safe during transportation, and the probability of the bolt torque wrench 7 colliding during transportation is reduced.
