Description

Technical Field

[0001] This utility model relates to the field of anchor modification technology, and in particular to a cold anchor modification device for railway engineering. Background Technology

[0002] In railway and bridge engineering, plastic sleeves (such as nylon sleeves) are commonly used to anchor bolts. After long-term use, they are prone to aging and thread damage, requiring replacement. This necessitates removing the plastic sleeves from the cavities placed on the sleepers. Traditional methods for removing plastic sleeves often involve drilling and core extraction with a water drill. Traditional anchor modification involves using a core extractor to create a hole, removing the nylon sleeve, manually removing debris from the hole, drying the hole with a hot air blower, and then injecting special adhesive before installing the nylon sleeve. This method generates mud and some waste and requires a large number of personnel. After installation, the nylon sleeve is not strong enough and requires 48 hours before the large bolts can be installed. This removal method is inefficient and wastes manpower. Therefore, it is necessary to provide a new cold anchor modification device to solve the above technical problems. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a cold anchor conversion device for railway engineering. The device uses a sliding plate to drive the drive unit and the locking unit to move up and down along the slide rail. The anchor conversion knife engages with the plastic sleeve. After the locking unit is locked with the top of the anchor conversion knife, the drive unit drives the locking unit to rotate. The locking unit drives the anchor conversion knife and the plastic sleeve to rotate synchronously, so that the anchor conversion knife and the plastic sleeve can be rotated out of the placement cavity. This improves the removal efficiency of the plastic sleeve and reduces labor costs.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a cold anchor conversion device for railway engineering, comprising an anchor conversion knife, a fastening component, a sliding component, and a lifting component. The fastening component has an inverted U-shaped structure. The sliding component is installed vertically on the outer side wall of the vertical end of the fastening component. The lifting component is installed on the side of the sliding component away from the fastening component to facilitate the lifting component moving up and down synchronously with the sliding component. The lifting component includes a driving part and a locking part. The output end of the driving part passes downward through the sliding component and connects to the locking part to facilitate the driving part driving the locking part to rotate synchronously. The inner wall of the locking part matches the shape of the top of the anchor conversion knife to facilitate clamping the anchor conversion knife.

[0005] Preferably, the fastening assembly includes a clamping plate, fixing bolts, and a carrying rod. The clamping plate has an inverted U-shaped structure, and the width of the horizontal end of the clamping plate is the same as the width of the rail. The vertical end of the clamping plate is provided with multiple threaded holes spaced horizontally. After the fixing bolts pass through the threaded holes, they are pressed against the side wall of the rail to restrict the movement of the clamping plate. The carrying rod is installed on the top of the horizontal end of the clamping plate.

[0006] Preferably, the sliding assembly includes a fixed plate and a sliding plate. The fixed plate is fastened to the fastening assembly. The side of the fixed plate away from the fastening assembly is provided with a slide rail in the vertical direction. The slide rails are arranged facing each other along the width direction of the fixed plate. The two ends of the sliding plate along the width direction are respectively embedded in the facing slide rails to facilitate the sliding plate to slide up and down along the slide rails. The end of the sliding plate away from the fixed plate is provided with a snap-fit ​​hole.

[0007] Preferably, the driving part is a torque wrench, which is engaged with the sliding assembly via a snap ring, and the engaging part is a sleeve.

[0008] Preferably, a grip sleeve is provided on the outer side wall of the handle, and the grip sleeve is an elastic silicone sleeve.

[0012] This utility model has the following advantages compared with the prior art:

[0013] 1. This utility model uses a sliding plate to drive the drive unit and the locking unit to move up and down along the slide rail. The modified anchor knife engages with the plastic sleeve. After the locking unit is locked with the top of the modified anchor knife, the drive unit drives the locking unit to rotate. The locking unit drives the modified anchor knife and the plastic sleeve to rotate synchronously, so that the modified anchor knife and the plastic sleeve can be rotated out of the placement cavity. This improves the removal efficiency of the plastic sleeve and reduces the labor intensity of the workers.

[0014] 2. The sliding plate of this utility model slides up and down along the slide rail. The driving part and the snap-fit ​​part are installed on the sliding plate.

[0024] like Figure 1 , Figure 2 As shown, this utility model discloses a cold anchor conversion device for railway engineering, including an anchor conversion knife 12, a fastening component, a sliding component, and a lifting component. The fastening component has an inverted U-shaped structure. The sliding component is installed vertically on the outer side wall of the vertical end of the fastening component. The lifting component is installed on the side of the sliding component away from the fastening component to facilitate the lifting component to move up and down synchronously with the sliding component. The lifting component includes a driving part and a locking part. The output end of the driving part passes downward through the sliding component and connects to the locking part to facilitate the driving part to drive the locking part to rotate synchronously. The inner wall of the locking part matches the top shape of the anchor conversion knife 12 to facilitate the locking of the anchor conversion knife 12.

[0025] The modified anchor cutter 12 is pressed into the plastic sleeve 3 to be removed via an interference fit. The cutting part of the modified anchor cutter 12 breaks the threads of the plastic sleeve 3 to form a groove to provide rotational engagement force. At the same time, a mechanical engagement surface is formed inside the plastic sleeve 3 to ensure that there is no relative slippage between the modified anchor cutter 12 and the plastic sleeve 3 during rotation. The fastening assembly is snapped onto the rail 4. The bottom of the rail 4 consists of a pad 2 and a sleeper 1. The sliding assembly is fastened to the outer wall of the vertical end of the fastening assembly. The sliding assembly is perpendicular to the rail 4. The drive unit passes vertically through the horizontal part of the sliding assembly and connects with the snap-fit ​​part. The drive unit and the snap-fit ​​part slide downward with the horizontal part of the sliding assembly, so that the snap-fit ​​part engages with the nut head at the top of the modified anchor cutter 12. The drive unit is activated, and the drive unit drives the snap-fit ​​part to move. The modified anchor cutter 12 rotates counterclockwise (the direction of rotation is the same as the direction of rotation of the plastic sleeve 3). The rotation of the modified anchor cutter 12 drives the plastic sleeve 3 to rotate synchronously and rotate out of the placement cavity of the sleeper 1. The upward rotation of the modified anchor cutter 12 and the plastic sleeve 3 pushes the locking part and the driving part to slide upward with the horizontal part of the sliding component until the plastic sleeve 3 is completely removed from the placement cavity. The position of the sliding component and the lifting component is fixed by setting the fastening component. The sliding component drives the lifting component to slide in the vertical direction so that the locking part can be locked in the top of the modified anchor cutter 12 in the vertical direction. The driving part drives the locking part to rotate and remove the modified anchor cutter 12 and the plastic sleeve 3 in the vertical direction, which improves the removal efficiency of the plastic sleeve 3 and reduces the labor intensity of the workers.

[0026] The fastening assembly includes a clamping plate 5, fixing bolts 6, and a handle 7. The clamping plate 5 has an inverted U-shaped structure. The width of the horizontal end of the clamping plate 5 is the same as the width of the rail 4. The vertical end of the clamping plate 5 is provided with multiple threaded holes spaced horizontally. After the fixing bolts 6 pass through the threaded holes, they are pressed against the side wall of the rail 4 to restrict the movement of the clamping plate 5. The handle 7 is installed on the top of the horizontal end of the clamping plate 5.

[0027] In this embodiment, the two vertical ends of the clamping plate 5 clamp the rail 4. The number of fixing bolts 6 is the same as the number of threaded holes. After the fixing bolts 6 are screwed into the threaded holes, they are screwed in until the end of the fixing bolts 6 is pressed against the side wall of the rail 4. The fixing bolts 6 in each threaded hole are pressed against the side wall of the rail 4, so that the clamping plate 5 is fixed in the current position of the rail 4. The handle 7 has an inverted U-shaped structure. The vertical end of the handle 7 away from the horizontal end is fixedly connected to the clamping plate 5. The cold anchor conversion device can be moved easily through the handle 7.

[0028] The sliding assembly includes a fixed plate 8 and a sliding plate 9. The fixed plate 8 is fastened to the fastening assembly. The side of the fixed plate 8 away from the fastening assembly is provided with a slide rail 13 in the vertical direction. The slide rails 13 are arranged facing each other along the width direction of the fixed plate 8. The two ends of the sliding plate 9 along the width direction are respectively embedded in the facing slide rails 13 to facilitate the sliding plate 9 to slide up and down along the slide rails 13. The end of the sliding plate 9 away from the fixed plate 8 is provided with a snap-fit ​​hole 14.

[0029] In this embodiment, the fixing plate 8 is a square plate, and the fixing plate 8 is fastened to the vertical end of the clamping frame plate 5. The slide rail 13 has a U-shaped structure and is arranged along the length direction of the fixing plate 8. The left and right sides of the end of the sliding plate 9 along the length direction are respectively provided with protrusions. The width of the protrusions is consistent with the width of the slide rail 13, so that they can be inserted into the slide rail 13. The sliding plate 9 moves up and down along the slide rail 13 through the protrusions. The driving part passes through the locking hole 14 in the vertical direction and connects with the locking part, so that the driving part and the locking part can be driven by the sliding plate 9 to move up and down synchronously along the slide rail 13.

[0030] To improve the stability of the connection between the fixing plate 8 and the clamping frame plate 5, a triangular reinforcing plate is provided on the top of the clamping frame plate 5, and the two right-angled sides of the triangular reinforcing plate are fastened to the clamping frame plate 5 and the fixing plate 8 respectively.

[0031] In one possible embodiment, there are multiple sliding plates 9, and the lengths of the multiple sliding plates 9 are different, so as to adapt to the plastic sleeves 3 with different distances from the rails 4. In use, a suitable sliding plate 9 is selected according to the distance between the plastic sleeves 3 and the rails 4, and the two ends of the sliding plate 9 are embedded in the slide rails 13, so that the sliding plate 9 moves up and down along the slide rails 13.

[0032] In another possible embodiment, the fixing plate 8 is a square plate, and a connecting plate is provided on the central axis along the width direction of the fixing plate 8. The connecting plate has a T-shaped structure, and its length is the same as that of the fixing plate 8. The vertical end of the connecting plate is fastened to the fixing plate 8, and there is a gap between the horizontal end of the connecting plate and the fixing plate 8 to form a slide rail 13. The sliding plate 9 has a first connecting member and a second connecting member at its length end. The first connecting member and the second connecting member are arranged facing each other and are both L-shaped structures. The vertical end of the first connecting member and the vertical end of the second connecting member are L-shaped structures. Both ends are tightly connected to the end of the sliding plate 9. The interval between the vertical ends of the first connector and the second connector is consistent with the width of the horizontal end of the connecting plate. The horizontal ends of the first connector and the second connector are parallel to the width direction of the sliding plate 9. The horizontal ends of the first connector and the second connector are respectively embedded in the two slide rails 13. The width of the horizontal end of the first connector and the width of the horizontal end of the second connector are consistent with the gap between the connecting plate and the fixed plate 8, so that the sliding plate 9 can move up and down along the slide rail 13.

[0033] The driving part is a torque wrench 10, which is engaged with the sliding assembly by a snap ring, and the engaging part is a sleeve 11.

[0034] In this embodiment, the torque wrench 10 is connected to the sliding plate 9 via a snap ring. After the wrench head of the torque wrench 10 passes downward through the snap hole 14, the socket 11 is fitted onto the wrench head of the torque wrench 10. To ensure the stability of the connection between the socket 11 and the wrench head, a pin is inserted into the socket 11 and the wrench head to prevent the socket 11 from falling off. Since the sliding plate 9 is set in the horizontal direction, the torque wrench 10 and the socket 11 remain vertical.

[0035] A grip sleeve, which is an elastic silicone sleeve, is fitted on the outer wall of the handle 7.

[0036] The horizontal end of the clamping plate 5 is a telescopic structure, which facilitates adjustment of the distance between the two vertical ends.

[0037] In this embodiment, the lateral end of the clamping plate 5 is set as a telescopic structure to facilitate adaptation to different types of rails 4.

[0038] Gaskets are provided on both the inner wall of the horizontal end and the inner wall of the vertical end of the clamping plate 5.

[0039] Shims are placed on the contact surface between the clamping plate 5 and the rail 4 to prevent the clamping plate 5 from causing wear on the rail surface of the rail 4.

[0040] The sliding plate 9 is a telescopic structure that facilitates adjustment of the distance between the snap-fit ​​hole 14 and the fixed plate 8.

[0041] In this embodiment, the sliding plate 9 is configured as a telescopic structure, which facilitates the adjustment of the distance between the snap-fit ​​hole 14 and the fixed plate 8, thereby adjusting the distance between the driving part and the snap-fit ​​part and the fixed plate 8, adapting to plastic sleeves 3 with different spacing of rails 4, and improving the applicability of the cold-modified anchor device.

[0042] In use, the anchor cutter 12 is pressed into the plastic sleeve 3 to be removed via an interference fit. The anchor cutter 12 forms a mechanical engagement surface within the plastic sleeve 3, ensuring no relative slippage between the anchor cutter 12 and the plastic sleeve 3 during rotation. Then, the clamping plate 5 is secured to the rail 4 using the fixing bolts 6. The sliding plate 9 slides downward along the slide rail 13, ensuring that the central axis of the clamping part overlaps with the central axis of the anchor cutter 12. The clamping part is then clamped to the nut at the top of the anchor cutter 12. The drive unit is activated, driving the clamping part to rotate the anchor cutter 12 counterclockwise. Since the anchor cutter 12 has formed a groove within the plastic sleeve 3, the rotation of the anchor cutter 12 transmits torque through the meshing of the groove, causing the plastic sleeve 3 to rotate synchronously and exit from the placement cavity of the sleeper 1. The anchor cutter 12 and the plastic sleeve 3 then rotate out of the placement cavity of the sleeper 1. The plastic sleeve 3 is rotated upwards to push the locking part, the driving part, and the sliding plate 9 to slide upwards along the slide rail 13. If the plastic sleeve 3 gets stuck during the rotation process, the driving part is rotated clockwise to loosen the engagement surface, and then the rotation continues counterclockwise until the plastic sleeve 3 is completely rotated out of the placement cavity of the sleeper 1. Then, a special workpiece is used to separate the anchor knife 12 from the plastic sleeve 3, and the clamping plate 5 is moved so that the locking part corresponds to the next plastic sleeve 3 to be removed. The anchor knife 12 is then inserted into the next plastic sleeve 3 to be removed, and the disassembly and assembly of the plastic sleeve 3 continues. This application improves the efficiency of rotating the plastic sleeve 3, reduces pollution, and reduces the labor intensity of the workers by using the sliding component to drive the driving part and the locking part to rotate the anchor knife 12 and the plastic sleeve 3 out of the placement cavity of the sleeper 1.

[0043] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent structural transformations made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
