Description

Technical Field

[0001] This invention relates to the field of railway track maintenance and construction technology, and in particular to a non-drilling and anchoring device for pre-embedded sleeves of railway concrete sleeper turnouts. Background Technology

[0002] During railway line operation, the pre-embedded sleeves and anchor bolts in the turnout area are prone to defects such as failure of pre-embedded sleeves and breakage of anchor bolts due to long-term exposure to alternating stresses such as vibration, tensile stress and shear generated by train operation. They need to be replaced in time.

[0003] The basic procedure for replacement is as follows: First, the old, failed bolts or embedded sleeves are drilled out of the concrete sleeper using a hollow drilling rig. Then, the remaining old anchoring material and debris in the hole are cleaned. Finally, the new embedded sleeve is inserted into the hole and anchoring agent is injected for re-anchoring. During both the drilling of the old sleeve and the subsequent anchoring operations, the drilling and anchoring equipment must be securely clamped onto the sleeper to ensure the accuracy of the drilling position and the verticality of the anchoring.

[0004] In actual operation, the existing equipment requires repeated adjustments to its front-to-back position and left-to-right alignment to ensure that the hollow drilling rig is precisely aligned with the pre-embedded casing to be drilled. Multiple clamping mechanisms require tightening multiple locking parts one by one, and front-to-back positioning and left-to-right calibration are carried out in steps. The operation involves many steps, is time-consuming, and the distributed tightening is prone to alignment deviation.

[0005] Furthermore, existing equipment has a complex structure and high cost. To achieve precise positioning and stable clamping of hollow drilling rigs, existing equipment is usually equipped with multiple sets of translation components, slides, and complex clamping mechanisms, which are not easy for construction personnel to move by hand, and have a large number of parts and high assembly requirements.

[0006] Therefore, based on the above analysis, there is still room for improvement in existing drilling and anchoring equipment. Summary of the Invention

[0007] To address the cumbersome clamping and alignment process in existing technologies, this invention provides a non-drilling and anchoring device for pre-embedded sleeves of railway concrete sleeper turnouts, including a main board with a drilling port and a hollow drilling rig device installed on the main board, wherein the axis of the hollow drill bit of the hollow drilling rig device corresponds to the axis of the drilling port.

[0008] Several observation ports are provided around the drill hole, distributed along its axis.

[0009] Two side plates are welded to both sides of the motherboard. The two side plates are distributed on the left and right sides of the motherboard and form a 90-degree angle with the bottom of the motherboard. A clamping cylinder is fixedly installed on the side plate. A clamping shaft with one end extending through the outer wall of the corresponding side plate is slidably inserted inside the clamping cylinder. A clamping plate is set at the end of the clamping shaft facing the motherboard. The motherboard has symmetrically opened limiting grooves that correspond to the two clamping plates. A limiting plate extending into the corresponding limiting groove is installed at the bottom of the clamping plate. A rubber layer is installed at the corresponding end of the two clamping plates. A drive assembly is installed at the end of the clamping shaft away from the bottom of the main board to move it so that the clamping plate clamps the outside of the sleeper.

[0010] In summary, this application includes at least one of the following beneficial technical effects: I. This invention utilizes the spherical fit between the roller groove at the end of the clamping shaft and the ball bearing on the clamping plate, along with the limiting and releasing of the fixing bolts. This allows the clamping plate to adaptively swing and fit on the inclined surface of the trapezoidal cross-section sleeper, and to lock and prevent swaying when not in use. At the same time, the guiding fit between the limiting plate and the limiting groove ensures that when the clamping shaft rotates and advances, the clamping plate only moves in the direction toward the sleeper without interference or deflection, thus achieving stable clamping of sleepers with different cross-sectional shapes.

[0011] Second, this invention uses a U-shaped water baffle on the main board to enclose the drill port, preventing the cooling water splashed during water drilling from flowing along the main board to the installation point of the lifting mechanism, thus avoiding corrosion and damage to the lifting mechanism due to water ingress. At the same time, the observation port on the side of the drill port allows the operator to quickly confirm the alignment of the drill bit axis with the old pre-embedded pipe before drilling, improving the accuracy and efficiency of the operation.

[0022] The following combination Figures 1 to 8 The embodiments of the present invention will be described in detail below.

[0023] This application discloses a non-crack drilling and anchoring device for pre-embedded sleeves of railway concrete sleepers and turnouts. It is used in the process of drilling and replacing old pre-embedded sleeves of sleepers. It can adaptively fit the trapezoidal cross-section of the sleeper to achieve stable clamping, avoid interference between the clamping shaft rotation and the clamping plate, and achieve rapid and accurate alignment of the drill bit through synchronous clamping and lateral fine adjustment functions.

[0024] Example 1: Reference Figures 1 to 5 As shown, the railway concrete sleeper turnout pre-embedded sleeve drilling and anchoring equipment includes a main board 1 with a drill port 10. A hollow drilling rig device 11 is also installed on the main board 1. The hollow drilling rig device 11 includes a lifting mechanism and a hollow drilling rig mounted on the lifting mechanism. The operator can control the hollow drilling rig to move vertically on the lifting mechanism, so that the drill bit of the hollow drilling rig moves towards the drill port 10 to drill the top of the sleeper. The axis of the hollow drill bit of the hollow drilling rig device 11 is connected to the drill port. Corresponding to the axis of drill 10, several observation ports 12 are provided around drill 10 along its axis. Initially, the main board 1 is placed on top of the sleeper. The axis of drill 10 is confirmed to correspond to the position of the old pre-embedded pipe on the sleeper through drill 10 and observation ports 12. The operator operates the hollow drilling machine device 11 to move downward and drill out the old pre-embedded pipe from the inside of the sleeper through the hollow drilling machine device 11. Then, the old pre-embedded pipe is removed and a new pre-embedded pipe is placed in the original position. Concrete mortar is then filled in to complete the replacement.

[0025] Two side plates 13 are welded to both sides of the main board 1, that is, the two side plates 13 are distributed on the left and right sides of the main board 1 respectively and form a 90-degree angle with the bottom of the main board 1. A clamping cylinder 14 is fixedly installed on the side plate 13. A clamping shaft 15 with one end extending through the outer wall of the corresponding side plate 13 is slidably inserted inside the clamping cylinder 14. A clamping plate 16 is provided at the end of the clamping shaft 15 facing the main board 1. The main board 1 has symmetrically opened limiting grooves 17 corresponding to the two clamping plates 16. A limiting plate 18 extending into the corresponding limiting groove 17 is installed at the bottom of the clamping plate 16. A rubber layer 19 is installed at the corresponding end of the two clamping plates 16. A driving component is installed at the end of the clamping shaft 15 away from the bottom of the main board 1 to drive it to move so that the clamping plate 16 clamps the outside of the sleeper.

[0026] The clamping shaft 15 is driven to move in the clamping cylinder 14 toward the corresponding side of the sleeper by the driving component. The limiting plate 18 on the top of the clamping plate 16 will move synchronously in the corresponding limiting groove 17, which will limit and guide the clamping plate 16. This will cause the rubber layer 19 on one side of the clamping plate 16 to contact the side wall of the sleeper. The rubber layer 19 is used to increase the friction between the clamping plate 16 and the sleeper. By clamping the side walls of the sleeper on both sides by the clamping plates 16, the main board 1 can be stably fixed on the sleeper.

[0027] The clamping shaft 15 has a groove at the end facing the corresponding clamping plate 16. A ball 110 is rotatably installed in the groove. A fixing bolt 111 corresponding to the outside of the ball 110 is threaded through the end of the clamping shaft 15. The end of the fixing bolt 111 is in contact with the outside of the ball 110.

[0028] That is, the cross-section of some sleepers is not vertical, but trapezoidal, that is, the sleeper is narrow at the top and wide at the bottom. Therefore, the operator can use a screwdriver to reach into the limiting groove 17 and engage with the top insertion interface of the fixing bolt 111, so that the fixing bolt 111 rotates and rises, no longer limiting and fixing the ball 110. Then, when the clamping shaft 15 drives the clamping plate 16 to contact the inclined surface of the sleeper, the clamping plate 16 will drive the ball 110 to rotate in the groove, so that the angle of the clamping plate 16 fits the outer wall of the sleeper, and further allows the rubber layer 19 to fully contact the outer wall of the sleeper. During the angular swing of the clamping plate 16, the corresponding limiting plate 18 at the top will also swing downward synchronously. However, the maximum swing angle of the clamping plate 16 will not cause the limiting plate 18 to completely detach from the limiting groove 17. Part of the outer side of the limiting plate 18 will still contact the inner wall of the limiting groove 17.

[0029] When the device is not in use, the driving fixing bolt 111 limits the ball 110, thereby indirectly preventing the swing angle of the clamp 16 from swinging and preventing it from shaking during transportation.

[0030] The top of the mainboard 1 is equipped with a U-shaped water baffle 112 corresponding to the drill port 10. The drill port 10 is located inside the U-shaped opening of the water baffle 112. During the drilling process, the hollow drill in the hollow drill device 11 may use a water drill, that is, water will be sprayed into the drill bit at the same time during the drilling process to cool the drill bit. Therefore, after the operator pulls the drill bit out of the drill port after the drilling is completed, the water inside the drill bit will splash onto the mainboard 1. The water baffle 112 can prevent the water on the mainboard 1 from flowing to the other side of the mainboard 1 and prevent the water from contacting the installation point of the lifting mechanism inside the hollow drill device 11, causing it to rust.

[0031] Reference Figure 4 and Figure 5 As shown, this is a driving assembly used to move the clamping shaft 15 so that the clamping plate 16 clamps the outside of the sleeper; specifically, the driving assembly includes threaded grooves 2 opened on the outside of each clamping shaft 15, each clamping shaft 15 is threadedly connected to the adjacent clamping cylinder 14 through its outer threaded groove 2, the clamping plate 16 is rotatably connected to the end of the clamping shaft 15, and a crank handle 20 is installed on the side of the clamping shaft 15 away from the clamping plate 16.

[0032] The operator can drive the corresponding clamping shaft 15 to rotate within the clamping cylinder 14 using the crank handles 20 on both sides. The clamping shaft 15, through the engagement of its outer threaded groove 2 with the clamping cylinder 14, can drive the corresponding clamping plate 16 to clamp the outer side of the sleeper. During this process, the fixing bolts 111 need to be loosened in advance to release the limit on the rolling ball 110. The rolling ball 110 and the rolling groove are in spherical engagement, which can both deflect and rotate. Therefore, when the clamping shaft 15 rotates and advances, the clamping plate 16 will not interfere with its rotation. Due to the constraint of the limiting plate 18 and the limiting groove 17, it can only move in the direction toward the sleeper. When it contacts the inclined surface of the sleeper with a trapezoidal cross section, the clamping plate 16 automatically swings up and down to fit the inclined surface, so that the rubber layer 19 is fully compressed, and a stable clamping is completed.

[0033] Example 2: Reference Figure 6 As shown, based on Embodiment 1, the present invention also provides another driving component; specifically, the driving component includes a push plate 3 installed on the side of the clamping shaft 15 away from the corresponding clamping plate 16, a support plate 30 installed in the middle of the main plate 1, a drive screw 31 rotatably passing through the middle of the support plate 30, the two sides of the drive screw 31 respectively penetrating to the outer wall of the corresponding push plate 3, and a crank handle 32 installed at both ends of the drive screw 31.

[0034] The operator uses the crank 32 to drive the drive screw 31 to rotate on the support plate 30. At this time, the drive screw 31 can drive the push plates 3 on both sides to move towards or away from the sleeper, so that the clamping plates 16 on both sides are clamped on the outside of the sleeper.

[0035] When the above-mentioned equipment is applied in conventional scenarios, such as when most pre-embedded pipes are pre-embedded in the middle of the sleeper, if the clamping plates 16 on both sides are driven and clamped separately by the operator according to the method of Embodiment 1, the feed of the clamping shafts 15 on both sides may deviate, resulting in a deviation in the clamping angle. The operator needs to make frequent adjustments. However, by using the drive screw 31 to drive the clamping plates 16 on both sides to clamp the sleeper synchronously, the above problems can be avoided.

[0036] Example 3: Reference Figure 7 and Figure 8 As shown, based on Embodiment 2, a lateral movement assembly for driving the main board 1 to move along the extension section of the sleeper is installed inside the clamping plate 16. Specifically, the lateral movement assembly includes several receiving cavities 4 opened in the clamping plate 16. A sliding block 40 is slidably installed in the receiving cavity 4. A roller 41 is rotatably installed at the end of the sliding block 40. Several vertical grooves corresponding to the receiving cavities 4 are opened on the outer side of the rubber layer 19. The vertical grooves are used to expose part of the outer side of the roller 41 to the outside of the rubber layer 19. A reset push spring 42 is installed between the sliding block 40 and the inner side wall of the corresponding receiving cavity 4.

[0037] After the clamping plate 16 drives the roller 41 to contact the outside of the sleeper, the front and rear positions of the main board 1 are limited. That is, the front and rear positions of the drill hole 10 are now aligned with the positions of the old pre-embedded pipes on the sleeper. However, there will be a slight deviation in the left and right directions. In actual operation, when the operator sees a deviation in the left and right directions, he will hammer the main board 1 to drive it to move laterally so that the drill hole 10 is aligned with the axis of the old pre-embedded pipe. Doing so will not only damage the main board 1, but also reduce efficiency.

[0038] Therefore, in this implementation process, after the clamping plate 16 drives the roller 41 to contact the outer side of the sleeper, the operator may encounter some deviation between the drill hole 10 and the old pre-embedded pipe. It is only necessary to drive the main board 1 to move laterally on the sleeper. At this time, the roller 41 will rotate on its corresponding sliding block 40 when it contacts the outer wall of the sleeper to prevent friction. After the position is adjusted, the operator can continue to indirectly drive the clamping plates 16 on both sides to move towards the sleeper through the crank handle 32, so that the roller 41 drives the sliding block 40 back into the corresponding receiving cavity 4, so that the rubber layer 19 contacts the outer wall of the sleeper. At this time, the rubber layer 19 can increase the contact area between the clamping plate 16 and the outer wall of the sleeper. The main board 1 can no longer move laterally. At this time, the main board 1 has completed the fixation in the front-back and left-right directions, and can continue the subsequent work.

[0039] After drilling is completed and clamping is canceled, the reset spring 42 will drive the roller 41 to move to the initial position through the sliding block 40 to complete the reset.

[0040] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and not restrictive.

[0041] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
