Description

Technical Field

[0001] The invention relates to the technical field of rail drilling, and in particular to a railway engineering rail drilling device with a protective structure. Background Art

[0002] When the railway engineering, electrical and other departments carry out maintenance and construction on the railway project, it is necessary to drill holes in the rails. The purpose of drilling holes is mostly to connect the rails or to install materials to reinforce the rails. A Chinese patent (publication number: CN105755916B) discloses a manual rail drilling machine, including a frame, which is composed of a crossbeam, a first vertical pole and a second vertical pole. A pair of clamps are hingedly arranged on the crossbeam; a pair of hydraulic cylinders are transversely fixedly arranged on the inner side of the crossbeam between the two clamps; push rods are respectively arranged in the two hydraulic cylinders, and the two push rods are respectively fixed on the clamps; a baffle is fixedly arranged below the hydraulic cylinder; a drill is transversely arranged at the lower end of the second vertical pole, and a screw is fixedly arranged at the tail of the drill, and the screw passes through the first vertical pole to the outside of the body frame, and a handle is arranged at the outer end of the frame of the screw.

[0003] However, the existing rail drilling device has some disadvantages when used, such as:

[0004] Most of the existing rail drilling devices are equipped with a mounting frame, and the mounting frame is fixed to one of the rails with screws, so that the rail drilling device is fixed on a single rail for drilling. However, the installation and disassembly of this rail drilling device during construction is relatively troublesome. When a train approaches, the drilling device cannot be quickly removed from the rail, resulting in damage to the drilling equipment and the train unit. At the same time, since most traditional drilling devices are fixed on a single rail for work, and the drilling devices are mostly arranged on one side of the rail, the uneven gravity distribution makes the drilling device vibrate during the drilling process, which easily causes the drill bit to tilt. At the least, the drilled holes do not meet the standards. At the worst, due to the tilt of the drill bit, the friction between the drill bit and the hole increases, causing the drilling device body to lose restriction and rotate and lose control under a large torque. In this case, since the drilling device body is out of control, it is difficult for the staff to shut down the device, resulting in the drilling device body continuing to pose a safety threat to the surrounding environment, so it is not safe to use. Summary of the invention

[0005] In view of this, the purpose of the present invention is to propose a railway engineering rail drilling device with a protective structure to solve the problem that most of the existing rail drilling devices are fixed on one of the rails by setting a mounting frame and fixing the mounting frame on one of the rails with screws, so as to fix the rail drilling device on a single rail for drilling. However, the installation and disassembly of this rail drilling device during construction is relatively troublesome. When a train approaches, the drilling device cannot be quickly removed from the rail, resulting in damage to the drilling equipment and the train unit. At the same time, since most traditional drilling devices are fixed on a single rail for work, and the drilling devices are mostly set on one side of the rail, the uneven gravity distribution makes the drilling device vibrate during the drilling process, which easily causes the drill bit to tilt. At the least, the drilled hole does not meet the standard. At the worst, due to the tilt of the drill bit, the friction between the drill bit and the hole increases, causing the main body of the drilling device to lose restriction and rotate and lose control under a large torque. In this case, since the main body of the drilling device is in an out-of-control state, it is difficult for the staff to close the device, resulting in the main body of the drilling device continuing to pose a safety threat to the surrounding environment, so it is not safe to use.

[0029] A rail drilling device for railway engineering with a protective structure comprises two first clamping rods 101 and two second clamping rods 103, wherein the first clamping rods 101 and the second clamping rods 103 are both L-shaped rods, the ends of the two first clamping rods 101 are commonly fixedly connected with a first slider 102, the ends of the two second clamping rods 103 are commonly fixedly connected with a second slider 104, the two first clamping rods 101 are slidably inserted on the outside of the second slider 104, the two second clamping rods 103 are slidably inserted on the inside of the first slider 102, the two first clamping rods 101 are slidably connected with the two second clamping rods 103 through the first slider 102, the two second clamping rods 103 are slidably connected with the two first clamping rods 101 through the second slider 104, the upper surfaces of the first slider 102 and the second slider 104 are fixedly installed with U-shaped handles 105, the U-shaped handles 105 are used to push or lift the first slider 102 and the second slider 104, the two Two telescopic rods 107 are transversely fixedly connected to the bottom of the first clamping rod 101, and two telescopic sleeves 106 are transversely fixedly connected to the bottom of the two second clamping rods 103. The other ends of the two telescopic rods 107 are inserted into the inside of the two telescopic sleeves 106. A motor mounting frame 108 is slidably installed on the outside of the two telescopic sleeves 106. A drilling motor 109 is transversely fixedly installed in the middle of the motor mounting frame 108. The drilling motor 109 is slidably installed on the two telescopic sleeves 106 through the motor mounting frame 108; the two first clamping rods 101 are fixedly connected at one end away from the first slider 102 by a transverse connecting rod, and the two second clamping rods 103 are fixedly connected at one end away from the second slider 104 by a transverse connecting rod. The ends of the two telescopic rods 107 are fixedly welded to the transverse connecting rod between the two first clamping rods 101, and the ends of the two telescopic sleeves 106 are fixedly welded to the transverse connecting rod between the two second clamping rods 103;

[0030] Among them, the two first clamping rods 101 are arranged parallel to each other on the outside of the two second clamping rods 103. Since the spacing between the two first clamping rods 101 and the two second clamping rods 103 is different, in order to enable the telescopic sleeve 106 and the telescopic insertion rod 107 to be arranged correspondingly, the telescopic sleeve 106 and the telescopic insertion rod 107 are respectively welded on the two transverse connecting rods, and the transverse connecting rod can also cooperate with the first slider 102 and the second slider 104 to respectively fix the two first clamping rods 101 and the two second clamping rods 103 to each other;

[0031] The two first clamping rods 101 and the two second clamping rods 103 are arranged in an L shape, which can clamp the two rails from the outside to the inside, and can leave enough working space for the drilling motor 109 inside the two rails;

[0032] The present invention provides two first clamping rods 101 and two second clamping rods 103, and utilizes the first slider 102 and the second slider 104 at the ends thereof to be slidably connected to each other, so that the two first clamping rods 101 and the two second clamping rods 103 can be quickly and simultaneously clamped on two rails. When removing, it is only necessary to pull the first slider 102 and the second slider 104 to the two ends respectively through the U-shaped handle 105, so that disassembly is relatively convenient, and the drilling equipment and the train unit will not be damaged due to the difficulty in removing the equipment. Then, the motor mounting frame 108 is used to slide the drilling motor 109 on the horizontally arranged telescopic sleeve 106 and the telescopic plug rod 107, so that the horizontal degree of the drilling motor 109 can be maintained, and the drilling equipment will not tilt after being vibrated due to the uneven gravity distribution, which greatly reduces the safety hazard. At the same time, the frame-shaped structure formed by the two first clamping rods 101 and the two second clamping rods 103 can avoid the safety threat caused by the uncontrolled drilling motor 109 flying upward.

[0033] Furthermore, a spring mounting plate 201 is slidably mounted on the outside of the two telescopic rods 107, and a propulsion spring 202 is laterally fixedly mounted on the middle of one side of the spring mounting plate 201 close to the drilling motor 109. The propulsion spring 202 and the drilling motor 109 are arranged on the same horizontal plane, and the spring mounting plate 201 and the propulsion spring 202 are both arranged corresponding to the tail of the drilling motor 109, and the propulsion spring 202 is used to push the drilling motor 109 in the working direction;

[0034] Among them, since it is necessary to apply pressure to the drilling motor 109 externally when the drilling motor 109 is drilling the rail so that the drill bit can obtain power to propel into the hole during the drilling process, a propulsion spring 202 is provided. Before starting the drilling motor 109, the propulsion spring 202 can be compressed by pushing the spring mounting plate 201. The compressed propulsion spring 202 has elastic potential energy that extends outward. The thrust generated by the elastic potential energy can provide continuous propulsion power for the drill bit at the end of the drilling motor 109, thereby facilitating better drilling work.

[0035] Furthermore, the bottom of the two telescopic rods 107 are both provided with a first tooth groove 306, and a rotating shaft 301 is installed on the side of the spring mounting plate 201 away from the propulsion spring 202 and near the top for transverse rotation. A clamping plate 302 is welded obliquely on the rotating shaft 301 corresponding to the telescopic rod 107, and the clamping plate 302 cooperates with the first tooth groove 306. An L-shaped paddle 303 is fixedly welded at the center of the rotating shaft 301, and a return spring 304 is fixedly connected to the lower surface of the top horizontal section of the L-shaped paddle 303. One end of the bottom of the return spring 304 is fixedly connected to the top of the spring mounting plate 201, and the L-shaped paddle 303 is used to rotate the clamping plate 302 through the rotating shaft 301.

[0036] Among them, since the spring mounting plate 201 needs to maintain a limit position after compressing the thrust spring 202 so that the thrust spring 202 can remain in a compressed state, thereby allowing the thrust spring 202 to generate continuous elastic potential energy, a clamping plate 302 that cooperates with the first tooth groove 306 is provided on the back side of the spring mounting plate 201. Because the clamping plate 302 is arranged at an angle, when the spring mounting plate 201 is pushed to squeeze the thrust spring 202, the first tooth groove 306 will not block the advancement of the clamping plate 302. When the spring mounting plate 201 loses its thrust, it is affected by the elastic potential energy of the thrust spring 202 extending outward, which will cause the spring mounting plate 201 to be subjected to a backward pushing force. However, since the inclined clamping plate 302 at this time can be firmly stuck in the first tooth groove 306, the spring mounting plate 201 cannot move back along the telescopic plug rod 107, thereby maintaining the spring mounting plate 201 to push the thrust spring 202. The squeezing of the spring 202 can make the elastic potential energy of the propulsion spring 202 act on the drilling motor 109; and when the drilling is completed and the spring mounting plate 201 needs to be pushed back, the user only needs to gently pull the L-shaped paddle 303 upwards to extend the reset spring 304 and drive the rotating shaft 301 to rotate. The rotation of the rotating shaft 301 will also drive the clamping plate 302 to rotate and disengage from the first tooth groove 306. At this time, the clamping plate 302 no longer has a limiting effect on the spring mounting plate 201, so that the spring mounting plate 201 can be pushed back to its original position. When the user releases the L-shaped paddle 303, the L-shaped paddle 303 is subjected to the pulling force generated by the retraction of the reset spring 304, so that the L-shaped paddle 303 returns to the initial position, and at the same time, the clamping plate 302 is also rotated to the initial position through the rotating shaft 301. At this time, the clamping plate 302 can again produce a one-way limiting effect on the spring mounting plate 201.

[0037] Furthermore, a spring bearing block 305 is horizontally arranged at the top of one side of the spring mounting plate 201 near the thrust spring 202, one end of the bottom of the return spring 304 is fixedly connected to the spring bearing block 305, and one end of the return spring 304 away from the L-shaped paddle 303 is fixedly connected to the spring mounting plate 201 through the spring bearing block 305.

[0038] Furthermore, the upper surfaces of the horizontal sections of the two first clamping rods 101 and the two second clamping rods 103 are both provided with second tooth grooves 401, and the upper surfaces of the first slider 102 and the second slider 104 are both movably connected with two clamping blocks 404, the two clamping blocks 404 arranged above the first slider 102 correspond to the two second clamping rods 103, and the two clamping blocks 404 arranged above the second slider 104 correspond to the two first clamping rods 101, the clamping blocks 404 cooperate with the second tooth grooves 401, and the center of the upper surface of the clamping blocks 404 is fixedly connected with a pull rod 404. 3. The tops of the pull rods 403 provided with the two clamping blocks 404 on the first slider 102 are commonly connected with a gripping rod 405. The tops of the pull rods 403 provided with the two clamping blocks 404 on the second slider 104 are commonly connected with another gripping rod 405. A baffle 402 is horizontally fixedly provided in the middle of the U-shaped handle 105. The pull rod 403 movably penetrates the baffle 402. A resistance spring 406 is sleeved on the outside of the pull rod 403. The resistance spring 406 is provided between the clamping block 404 and the baffle 402. The resistance spring 406 is used to push the clamping block 404 downward.

[0039] When in use, when the user needs to unfold the first clamping rod 101 and the second clamping rod 103 to clamp the device on the rail, the user can hold the U-shaped handle 105 and lift the gripping rod 405 upwards. At this time, the gripping rod 405 pulls the clamping block 404 upwards through the pull rod 403 to disengage it from the second tooth groove 401. At the same time, the resistance spring 406 is also compressed to generate elastic potential energy extending outward. At this time, the clamping block 404 no longer limits the first slider 102 and the second slider 104. Therefore, the user can push the first slider 102 and the second slider 104 toward each other through the U-shaped handle 105. After the rod 101 and the second clamping rod 103 are fully unfolded, they are clamped on the outer sides of the two rails, and then the holding rod 405 is released. Since the holding rod 405 loses the pulling force of the external force, at this time, the resistance spring 406 arranged at the bottom pushes the block 404 away from the baffle 402 through its reserved elastic potential energy. Since the baffle 402 is fixed on the U-shaped handle 105, the resistance spring 406 can only push the block 404 downward, and the pushed block 404 contacts the second tooth groove 401 again. Since the second tooth groove 401 arranged above the first clamping rod 101 is a one-way tooth inclined toward the first slider 102, and the second tooth groove 401 arranged on the second clamping rod 103 The second tooth groove 401 is a one-way tooth inclined toward the second slider 104, so when the two sliders move toward each other, the block 404 can be limited by the second tooth groove 401, and when the two sliders move in the opposite direction, the block 404 cannot be limited by the second tooth groove 401. Therefore, after the first clamping rod 101 and the second clamping rod 103 are clamped at appropriate positions outside the two rails, the first slider 102 and the second slider 104 can be pushed in opposite directions through the U-shaped handle 105, thereby shrinking the space in the middle of the first clamping rod 101 and the second clamping rod 103, so that the first clamping rod 101 and the second clamping rod 103 can be firmly clamped between the two rails. On the outside, and because the two sliders are limited by the block 404 and the second tooth groove 401 when they move toward each other, the two sliders are always limited by the block 404 without lifting the holding rod 405, that is, the first clamping rod 101 and the second clamping rod 103 can remain clamped on the two rails, thereby realizing the rapid installation of the bottom drilling motor 109. During disassembly, it is only necessary to lift the holding rod 405 to make the two sliders lose the limitation of the block 404, and then push the U-shaped handle 105 toward each other to unfold the first clamping rod 101 and the second clamping rod 103, thereby realizing the rapid installation and disassembly of the drilling motor 109.

[0040] Furthermore, a socket 501 is fixedly installed at the bottom of the spring mounting plate 201, and the power input end of the socket 501 is electrically connected to an external power supply. The power input end of the drilling motor 109 is electrically connected to a plug 502 through a wire, and the plug 502 is movably plugged into the socket 501, and the plug 502 is electrically connected to the socket 501;

[0041] Among them, the length of the wire connected between the plug 502 and the drilling motor 109 is set to be shorter than that when the propulsion spring 202 is in the extended state. After the drilling motor 109 is set at a predetermined position and the spring mounting plate 201 is pushed to squeeze the propulsion spring 202 to limit it, the plug 502 is plugged into the socket 501 to power the drilling motor 109. When the drill bit normally penetrates the rail, the remaining drill bits can pass through the hole. Under the push of the elastic potential energy of the propulsion spring 202, the drill bit of the drilling motor 109 will quickly enter the drilled hole, and the propulsion spring 202 can be fully extended. Since the length of the wire connected between the plug 502 and the drilling motor 109 is set to be shorter than that when the propulsion spring 202 is in the extended state, Therefore, after the propulsion spring 202 is fully extended, the plug 502 will be carried by the drilling motor 109 to move away from the socket 501, and the drilling motor 109 can be powered off immediately, so as to timely eliminate the safety threat caused by the drilling motor 109 in the working state; when the drilling motor 109 rotates out of control under special circumstances, the rotation of the drilling motor 109 body will carry the plug 502 with it, and the plug 502 can be pulled off from the socket 501 in time, and the power of the out-of-control drilling motor 109 is promptly cut off, so as to timely eliminate the safety threat caused by the drilling motor 109 in the out-of-control state, and can effectively avoid the situation that the drilling motor 109 cannot be turned off after it loses control, causing it to continue to pose a safety threat to the surrounding environment;

[0042] Among them, in order to make the power supply of the drilling motor 109 safer, a starting switch can be set on the circuit connecting the socket 501 and the external power supply. The starting switch is as far away from the device as possible, so that when the plug 502 is inserted into the socket 501, the staff can remotely start the drilling motor 109 through the starting switch to make it work, thereby avoiding the drilling motor 109 suddenly working when plugged in and posing a safety threat to the staff who are plugged in.

[0043] Furthermore, a pad 600 is fixedly welded to one end of the two first clamping rods 101 away from the first slider 102 and one end of the two second clamping rods 103 away from the second slider 104. The pad 600 is made of rubber material and is used to increase the friction between the first clamping rod 101 and the second clamping rod 103 and the rail.

[0044] Among them, since the drilling motor 109 will produce slight vibration when drilling holes for the rails, by setting a rubber pad 600 at the position where the first clamping rod 101 and the second clamping rod 103 contact the rails, the material effect of the pad 600 can be used to reduce the vibration of the drilling motor 109, and at the same time, the friction force at the position where the first clamping rod 101 and the second clamping rod 103 contact the rails can be increased, thereby preventing the position where the first clamping rod 101 and the second clamping rod 103 contact the rails from being displaced due to the vibration of the drilling motor 109.

[0045] In summary, during use, when the user needs to unfold the first clamping rod 101 and the second clamping rod 103 in order to clamp the device on the rail, the user can hold the U-shaped handle 105 and lift the gripping rod 405 upwards. At this time, the gripping rod 405 pulls the clamping block 404 upwards through the pull rod 403 to disengage it from the second tooth groove 401. At the same time, the resistance spring 406 will also be compressed to generate elastic potential energy extending outward. At this time, the clamping block 404 will no longer limit the first slider 102 and the second slider 104. Therefore, the user can push the first slider 102 and the second slider 104 toward each other through the U-shaped handle 105, and wait for the first clamping After the holding rod 101 and the second clamping rod 103 are fully unfolded, they are clamped on the outer sides of the two rails, and then the holding rod 405 is released. Since the holding rod 405 loses the pulling force of the external force, at this time, the resistance spring 406 arranged at the bottom pushes the block 404 away from the baffle 402 through its reserved elastic potential energy. Since the baffle 402 is fixed on the U-shaped handle 105, the resistance spring 406 can only push the block 404 downward, and the pushed block 404 contacts the second tooth groove 401 again. Since the second tooth groove 401 arranged above the first clamping rod 101 is a one-way tooth inclined toward the first slider 102, and the second clamping rod 103 is arranged The second tooth groove 401 at the top is a one-way tooth inclined toward the second slider 104, so when the two sliders move toward each other, the block 404 can be limited by the second tooth groove 401, and when the two sliders move in the opposite direction, the block 404 cannot be limited by the second tooth groove 401. Therefore, after the first clamping rod 101 and the second clamping rod 103 are clamped at appropriate positions outside the two rails, the first slider 102 and the second slider 104 can be pushed in opposite directions through the U-shaped handle 105, thereby shrinking the space in the middle of the first clamping rod 101 and the second clamping rod 103, so that the first clamping rod 101 and the second clamping rod 103 can be tightly clamped between the two rails. The two sliders are located outside the rails, and because they are limited by the block 404 and the second tooth groove 401 when they move toward each other, the two sliders are always limited by the block 404 without lifting the gripping rod 405, that is, the first clamping rod 101 and the second clamping rod 103 can remain clamped on the two rails, thereby realizing the rapid installation of the bottom drilling motor 109. When disassembling, the two sliders only need to be lifted by the gripping rod 405 to make the two sliders lose the limit of the block 404, and then the U-shaped handle 105 can be pushed toward each other to unfold the first clamping rod 101 and the second clamping rod 103, thereby realizing the rapid installation and disassembly of the drilling motor 109.

[0046] Since the spring mounting plate 201 needs to maintain a limit position after compressing the thrust spring 202 in order to keep the thrust spring 202 in a compressed state, thereby allowing the thrust spring 202 to generate continuous elastic potential energy, a clamping plate 302 that cooperates with the first tooth groove 306 is provided on the back side of the spring mounting plate 201. Because the clamping plate 302 is arranged at an angle, when the spring mounting plate 201 is pushed to squeeze the thrust spring 202, the first tooth groove 306 will not block the advancement of the clamping plate 302. When the spring mounting plate 201 loses its thrust, it is affected by the elastic potential energy of the thrust spring 202 extending outward, which will cause the spring mounting plate 201 to be subjected to a backward pushing force. However, at this time, the inclined clamping plate 302 can be firmly stuck in the first tooth groove 306, making it impossible for the spring mounting plate 201 to move back along the telescopic rod 107, thereby maintaining the spring mounting plate 201's effect on the thrust spring. The spring 202 is squeezed, and the elastic potential energy of the propulsion spring 202 can be applied to the drilling motor 109. When the drilling is completed and the spring mounting plate 201 needs to be pushed back, the user only needs to gently pull the L-shaped paddle 303 upwards to extend the return spring 304 and drive the rotating shaft 301 to rotate. The rotation of the rotating shaft 301 will also drive the clamping plate 302 to rotate and disengage from the first tooth groove 306. At this time, the clamping plate 302 no longer has a limiting effect on the spring mounting plate 201, so that the spring mounting plate 201 can be pushed back to its original position. When the user releases the L-shaped paddle 303, the L-shaped paddle 303 is subjected to the pulling force generated by the retraction of the return spring 304, so that the L-shaped paddle 303 returns to the initial position. At the same time, the clamping plate 302 is also rotated to the initial position through the rotating shaft 301. At this time, the clamping plate 302 can produce a one-way limiting effect on the spring mounting plate 201 again.

[0047] The present invention provides two first clamping rods 101 and two second clamping rods 103, and utilizes the first slider 102 and the second slider 104 at the ends thereof to be slidably connected to each other, so that the two first clamping rods 101 and the two second clamping rods 103 can be quickly and simultaneously clamped on two rails. When removing, it is only necessary to pull the first slider 102 and the second slider 104 to the two ends respectively through the U-shaped handle 105, so that disassembly is relatively convenient, and the drilling equipment and the train unit will not be damaged due to the difficulty in removing the equipment. Then, the motor mounting frame 108 is used to slide the drilling motor 109 on the horizontally arranged telescopic sleeve 106 and the telescopic plug rod 107, so that the horizontal degree of the drilling motor 109 can be maintained, and the drilling equipment will not tilt after being vibrated due to the uneven gravity distribution, which greatly reduces the safety hazard. At the same time, the frame-shaped structure formed by the two first clamping rods 101 and the two second clamping rods 103 can avoid the safety threat caused by the uncontrolled drilling motor 109 flying upward.
