Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of track operation, and in particular to a full-automatic track bolt operation and maintenance device. BACKGROUND

[0002] After the track is laid, the track will expand and contract due to temperature changes throughout the year, and the internal stress of the track will increase sharply, which will affect the safe operation of the train to some extent. Therefore, it is necessary to regularly loosen the track bolts to release the stress of the track, so as to achieve the effect of track maintenance. The existing track bolt operation and maintenance device moves on two tracks through four rollers arranged thereon to realize the movement of the robot. When there is ice on the track, the device is easy to slip when walking on the track, and the following defects exist in the use process:

[0003] 1. When the device is tightening or loosening the bolt, the device itself needs to provide strong counterforce on the track to maintain stability. The extremely low friction of the ice surface makes the driving wheel of the robot unable to firmly "grab" the track surface, resulting in easy slipping or even displacement of the robot when the torque is applied. This not only causes "false tightening", that is, the device records that the torque value has reached the standard, but in fact, due to slipping, the bolt is not applied with enough effective torque, leaving a serious safety hazard; more dangerously, the control system of the device may output an overload torque instantaneously to overcome the slipping, and once the wheel suddenly grabs the ground, this huge force will be directly applied to the bolt, which is easy to cause the bolt to be twisted off or the thread to be damaged, changing the maintainer into a destroyer.

[0004] 2. The ice layer on the surface of the track will greatly reduce the friction between the wheel and the rail, resulting in serious slipping and sliding of the device during movement. This is like a car losing control and drifting on the ice. The device relies on precise encoders and positioning systems to calculate the distance traveled, but the wheel spinning and slipping will make the mileage calculation completely distorted, causing it to be unable to stop at the predetermined bolt operation position. As a result, it may stop too early or pass the target point, requiring repeated positioning adjustments, which greatly reduces the work efficiency. More seriously, on a line with a slope, the device may even risk sliding due to insufficient grip, endangering the safety of itself and the line equipment. SUMMARY

[0005] In view of the problems in the prior art that the ice surface causes the device to slip and displace, cannot accurately stop at the operation point, the positioning efficiency is greatly reduced, and there is a risk of sliding, and at the same time, the device slips when tightening the bolt due to insufficient grip, causing false tightening or torque overload, which not only hides safety hazards but also easily damages the bolt itself, a full-automatic track bolt operation and maintenance device is proposed.

[0019] The beneficial effects of the present application are as follows:

[0020] 1. The cooperative design of the positioning unit and the execution assembly solves the operation safety problem in the low-friction environment of the ice surface from the root. After the suction cup of the positioning assembly is adsorbed to the track, the bottom framework can be fixed together with the positioning wheel, so as to avoid slipping or displacement of the device when the bolt torque is applied, completely eliminate the "false tightening" phenomenon, i.e., prevent the device from recording torque compliance but not actually applying effective torque to the bolt, ensure the connection strength of the track, and eliminate the hidden danger of line operation safety. At the same time, the execution assembly precisely adjusts the torque by controlling the output current of the motor reducer module, avoids the control system from outputting an overload torque to overcome the slipping, prevents the bolt from being twisted off or the thread from being damaged when the wheel suddenly grabs the ground, avoids the device from changing from a "maintainer" to a "destroyer", and significantly reduces the damage of the track equipment and the risk of line failure.

[0021] 2、Through the encoder of the walking assembly, the position information of the positioning sensor can be converted into a distance signal, the traveling motor is accurately controlled, the mileage calculation distortion caused by the wheel idling is avoided, the device is prevented from stopping early or passing through the target point, and the time cost of repeatedly adjusting the position is reduced. In view of the risk of slope coasting, the adsorption fixing function of the positioning unit can firmly lock the position of the device, even if the track surface has an ice layer and insufficient grip, the device can be stably parked, and an additional anti-skid fixing structure is not needed. In addition, the compression and pressing module of the execution assembly can drive the screwing drum to adapt to bolts of different heights, so that the device can work continuously and efficiently under complex conditions without replacing the working parts.

[0022] 3、Through detachable connection and wear protection, the equipment maintenance cost and operation difficulty are effectively reduced. In the positioning assembly, the connecting rod and the U-shaped seat are detachably connected, and the positioning slide plate and the U-shaped seat are inserted and matched, so that the device can be quickly assembled during installation. If the vulnerable parts such as guide wheels and suction cups fail later, they can also be conveniently disassembled and replaced, reducing maintenance time and labor cost. At the same time, the inclined hole and the vertical hole of the moving away assembly can make the lifting block drive the guide wheel to move horizontally first and then vertically upward when the lifting block rises, avoiding direct friction between the guide wheel and the track body to cause wear, prolonging the service life of the guide wheel and reducing the replacement frequency of vulnerable parts. The overall device is controlled by the control box, and each component operates cooperatively without manual intervention. The operator only needs to send instructions through the control box to realize fully automatic operation, reduce the requirement for the skill level of the operator, and reduce human operation errors.

[0042] Reference Figure 5 and Figure 6The moving-away assembly 3 comprises a moving-away spring 31 fixedly connected between the connecting rod 22 and the inner wall of the sliding groove, and a through groove is formed in the lifting block 21 and communicates with the inner side of the sliding groove, a guide rod 32 is slidably connected in the through groove, the guide rod 32 is fixedly connected with the connecting rod 22, a side plate 33 is fixedly connected to the first L-shaped plate 15, an inclined hole 34 is formed in the side plate 33, and a vertical hole 35 is formed in the side plate 33 and communicates with the inclined hole 34, and the guide rod 32 is slidably connected with the inner sides of the inclined hole 34 and the vertical hole 35.

[0043] Specifically, when the lifting block 21 moves upward, the connecting rod 22 is driven to move upward, the guide rod 32 slides in the inclined hole 34, the guide rod 32 is horizontally driven to move under the action of the inclined hole 34, the connecting rod 22 slides in the inner side of the sliding groove, and the moving-away spring 31 is compressed, when the lifting block 21 continues to rise, the guide rod 32 slides into the vertical hole 35 from the inclined hole 34, the connecting rod 22 vertically rises under the action of the vertical hole 35, and then the U-shaped seat 23 is horizontally moved for a distance and then vertically moves upward, so that the U-shaped seat 23 vertically moves upward without friction of the guide wheel 24 on the track body 1, and the use of the guide wheel 24 is affected.

[0044] Embodiment 2, refer to Figure 7 As a second embodiment of the present application, the difference between the second embodiment and the first embodiment is that the positioning assembly 4 comprises a positioning sliding plate 41 limitingly and slidably connected to the U-shaped seat 23, a cylinder 42 is fixedly connected to the top of the positioning sliding plate 41, and a suction disc 43 is fixedly connected to the top of the cylinder 42 and communicates with the inner side of the cylinder 42.

[0045] Specifically, when the U-shaped seat 23 moves upward, the positioning sliding plate 41 is driven to move, the suction disc 43 is driven to move upward through the cylinder 42, the track body 1 is adsorbed under the action of the suction disc 43, the U-shaped seat 23 is positioned, the bottom frame 11 is positioned under the joint action of the positioning wheel 16 and the U-shaped seat 23, and the bottom frame 11 is prevented from sliding when the track body 1 has ice layer and causes inaccurate positioning. Since the connecting rod 22 is detachably connected with the U-shaped seat 23, when the device is placed on the track body 1, the U-shaped seat 23 is connected with the connecting rod 22, and the positioning sliding plate 41 is inserted into the U-shaped seat 23.

[0046] Refer to Figures 8-12, the adsorption component further comprises a driving assembly 5 installed on the first L-shaped plate 15, a transmission assembly 6 is installed on the driving assembly 5, and a deflation assembly 7 is installed on the transmission assembly 6; the driving assembly 5 comprises a driving motor 51 fixedly connected to the first L-shaped plate 15, a driving disc 52 rotationally connected to an output shaft of the driving motor 51, an arc-shaped cavity 53 formed in the driving disc 52, a guide block 54 slidably connected to an inner side of the arc-shaped cavity 53, and a threaded column 55 fixedly connected to a bottom of the driving disc 52 and threadedly connected to the lifting block 21.

[0047] Specifically, the driving motor 51 is started to drive the guide block 54 to rotate, and under the action of the arc-shaped cavity 53, the driving disc 52 is driven to rotate, and in turn, the threaded column 55 is driven to rotate, so that the lifting block 21 slides on the threaded column 55.

[0048] Referring to Figure 10 , the transmission assembly 6 comprises a sleeve 61 rotationally connected to the positioning sliding plate 41, an inner rod 62 limitingly and slidably connected to a top of the sleeve 61, and the threaded column 55 penetrates through the inner rod 62 and is fixedly connected to the output shaft of the driving motor 51.

[0049] Specifically, when the driving motor 51 rotates, the inner rod 62 is driven to rotate, and since the inner rod 62 is limitingly and slidably connected to the sleeve 61, the sleeve 61 is driven to rotate.

[0050] Referring to Figure 11 and Figure 12 , the deflation assembly 7 comprises a sealing plate 71 sealingly and rotationally connected to an inner side of the cylinder body 42, a connecting shaft 72 fixedly connected to a bottom of the sealing plate 71, a driven wheel 73 fixedly sleeved on the connecting shaft 72, a driving wheel 74 fixedly sleeved on the sleeve 61, a belt 75 sleeved between the driving wheel 74 and the driven wheel 73, a gas hole 76 formed in the sealing plate 71 and communicating with the inner side of the cylinder body 42, and an L-shaped hole 77 formed in the sealing plate 71.

[0051] Specifically, when the U-shaped seat 23 moves upward, the positioning sliding plate 41 is driven to move upward, so that the inner rod 62 slides in the inner side of the sleeve 61, and when the suction cup 43 is in contact with the track body 1, the gas in the suction cup 43 is discharged. Since the sealing plate 71 seals between the suction cup 43 and the cylinder body 42, after the gas in the suction cup 43 is discharged, the suction cup 43 can be adsorbed on the track body 1. When the U-shaped seat 23 moves downward, due to the suction cup 43 being tightly adsorbed on the track body 1, the U-shaped seat 23 cannot move downward, and when the driving motor 51 starts, the guide block 54 is first driven to rotate, so that the guide block 54 rotates in the inner side of the arc-shaped cavity 53, and when the guide block 54 is in contact with the inner wall of the arc-shaped cavity 53, the driving disc 52 is driven to rotate, that is, when the driving motor 51 rotates, the inner rod 62 immediately rotates, and the driving disc 52 is subsequently rotated, that is, the threaded column 55 is subsequently rotated, so that the gas in the suction cup 43 is first discharged, and then the U-shaped seat 23 starts to descend. The inner rod 62 rotates to drive the sleeve 61 to rotate, and the U-shaped seat 23 moves up and down, that is, the driving motor 51 is subjected to positive and reverse rotation. When the driving motor 51 rotates forward, the U-shaped seat 23 rises, and the suction cup 43 does not need to be discharged. The one-way bearing is arranged between the driving wheel 74 and the sleeve 61, and the driving wheel 74 rotates under the action of the belt 75 to drive the driven wheel 73 to rotate. Under the action of the one-way bearing, when the sleeve 61 rotates forward, the driving wheel 74 does not rotate. When the driving motor 51 reverses, the U-shaped seat 23 descends, the driving wheel 74 drives the driven wheel 73 to rotate through the belt 75, and then drives the connecting shaft 72 to rotate, drives the sealing plate 71 to rotate, and since the L-shaped hole 77 is formed in the sealing plate 71, the L-shaped hole 77 is initially sealed, and as the sealing plate 71 rotates, the L-shaped hole 77 and the air hole 76 will be connected in an instant, so that the external gas enters the suction cup 43 from the air hole 76 and the L-shaped hole 77, so that the suction cup 43 is filled with gas, and the adsorption on the track body 1 is released. The remaining structure is the same as that of example 1.

[0052] Example 3, refer to Figure 13 This is the third embodiment of the application, which is different from the second embodiment: it further comprises a walking assembly 8 installed on the bottom frame 11, the walking assembly 8 comprises two second L-shaped plates 81 fixedly connected to the bottom frame 11 in a symmetrical distribution, and a walking wheel 82 rotatably connected between the two second L-shaped plates 81, wherein one of the second L-shaped plates 81 is fixedly connected with an encoder 83, and the encoder 83 is fixedly connected with a traveling motor 84.

[0053] Specifically, the device is placed on the track to travel, the bottom skeleton 11 bottom positioning sensor 14 detects the track bolt position information sent to the control box 12, the control box 12 sends instructions to the encoder 83, the encoder 83 converts the position information detected by the positioning sensor 14 into distance information, and then controls the travel motor 84 to make the device travel above the track bolt. When the travel motor 84 stops running, the control box 12 controls the drive motor 51 to start, and the bottom skeleton 11 is positioned.

[0054] Referring to Figure 14 Further comprising an execution assembly 9 mounted on the bottom skeleton 11, the execution assembly 9 comprising a motor reducer module 91 fixedly connected to the bottom skeleton 11, a spline shaft 92 fixedly connected to the motor reducer module 91, a spiral cylinder 93 slidingly connected to the spline shaft 92, a lower pressing block 94 rotatably connected to the spiral cylinder 93, a twisting cylinder 95 fixedly connected to the bottom of the spiral cylinder 93, and a compression pressing module 96 fixedly connected to the motor reducer module 91, the lower pressing block 94 being fixedly connected to the compression pressing module 96.

[0055] Specifically, the compression pressing module 96 in the execution assembly 9 drives the rotating spiral cylinder 93 to slide along the spline shaft 92 to the track bolt, until the twisting cylinder 95 is buckled on the track bolt to loosen and tighten the bolt. During the tightening of the bolt, the output torque can be accurately controlled by controlling the output current of the motor reducer module 91, so that the track bolt reaches the torque value required by the railway standard, thereby realizing accurate maintenance of the track. In addition, the execution assembly 9 comprises the compression pressing module 96, which drives the lower pressing block 94 to move downward, so that the twisting cylinder 95 moves downward above the bolt, which can realize maintenance work of bolts of different heights, complete the maintenance work of the track bolt installation error larger section, and improve the practicability of the device. The rest of the structure is the same as that of embodiment 2.

[0056] In summary, the working principle of the present application is as follows: the bottom skeleton 11 provides a mounting base for each component, the battery 13 supplies power, and the control box 12 receives signals from the positioning sensor 14 and controls the overall operation. During the moving stage, the walking assembly 8 is activated, the travel motor 84 drives the walking wheels 82 to roll along the track, and the encoder 83 converts the bolt position information detected by the positioning sensor 14 into a distance signal, so that the precision control device can stop at the work point and avoid positional deviation caused by ice surface slipping. After stopping, the positioning unit is activated to enhance stability. The lifting block 21 of the guiding assembly 2 slides along the first L-shaped plate 15, driving the guide wheels 24 to closely adhere to the track and enhance the moving guiding property; the moving assembly 3 cooperates, when the lifting block 21 rises, the guide rod 32 first slides along the inclined hole 34 to horizontally move away the guide wheels 24, and then vertically rises along the vertical hole 35 to avoid damage of the guide wheels 24 caused by friction with the track. At the same time, the suction cups 43 of the positioning assembly 4 rise with the U-shaped seat 23 and adsorb the track, combining with the positioning wheels 16 to fix the bottom skeleton 11, offsetting the low friction of the ice surface, preventing slipping or displacement during work, and avoiding "false tightening" and bolt damage. When moving is needed, the drive motor 51 is reversed, the sealing plate 71 of the deflation assembly 7 is driven to rotate by the transmission assembly 6, the L-shaped hole 77 is communicated with the air hole 76, the suction cups 43 are deflated to release adsorption.
