The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0025] In the present invention, unless otherwise specified, directional words such as "up, down, top, bottom" are usually used with reference to the directions shown in the drawings, or with reference to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention.

[0026] In order to solve the problem of low cutting efficiency of the anchor rod cutting device in the prior art, the utility model provides an anchor rod cutting device.

[0027] like Figure 1 and Figure 2 As shown, the anchor rod cutting device includes a platform structure 10, a cutting seat, a cutting structure and a clamping structure. The platform structure 10 has a mounting surface; the cutting seat is arranged on the mounting surface, and the cutting seat includes a guide plate 22 and a clamping plate 23 connected at an angle, the guide plate 22 has a guide through hole 221, and the clamping plate 23 has a clamping groove 231, the clamping groove 231 is used to clamp with the anchor rod to be cut, when the anchor rod to be cut is clamped with the clamping groove 231, at least part of the anchor rod to be cut corresponds to the guide through hole 221; the cutting structure is arranged on the mounting surface and is located on one side of the cutting seat, the cutting structure includes a cutting head 31, the cutting head 31 is retractably arranged in the direction of approaching and away from the cutting seat, when the cutting head 31 extends and passes through the guide through hole 221, the projection of the cutting head 31 on the clamping plate 23 at least partially covers the clamping groove 231; the clamping structure is arranged on the cutting seat and is located on the side of the clamping plate 23 away from the guide plate 22, and the clamping structure is used to clamp the anchor rod to be cut on the cutting seat.

[0028] The platform structure 10 has a mounting surface, so that the platform structure 10 provides a mounting position for the cutting seat, the cutting structure and the clamping structure, which is conducive to ensuring the reliability of the cutting seat, the cutting structure and the clamping structure. By setting the clamping plate 23 with a clamping groove 231, the clamping groove 231 provides a mounting position for the anchor rod to be cut. When the anchor rod to be cut needs to be cut, a mark is made at the position to be cut, and the front and rear parts of the marked position of the anchor rod to be cut are aligned to facilitate clamping, fixing and cutting by the clamping structure. The anchor rod to be cut is passed through the clamping groove 231 until the marked position is aligned with the opening of the clamping groove 231. At this time, since at least a portion of the anchor rod to be cut corresponds to the guide through hole 221, the cutting head 31 can contact the anchor rod to be cut after extending and passing through the guide through hole 221, thereby achieving the cutting action of the anchor rod to be cut. The clamping structure is arranged on the cutting seat and is located on the side of the clamping plate 23 away from the guide plate 22. The clamping structure is used to clamp and fix the anchor rod to be cut on the cutting seat. This arrangement enables the clamping structure to firmly limit the anchor rod to be cut on the cutting seat during the cutting process of the anchor rod to be cut, thereby ensuring that the anchor rod to be cut will not be displaced due to the force applied by the cutting head 31, and at the same time, it can avoid the risk of the anchor rod to be cut being separated from the clamping groove 231, which is conducive to ensuring the cutting accuracy and cutting efficiency.

[0029] In summary, the anchor rod cutting device of the present application enables the anchor rod to be accurately positioned during cutting, avoiding deviation during the cutting process, ensuring a smooth cut surface, and improving work efficiency. In actual use, this can significantly reduce the waste of anchor rods caused by inaccurate cutting. At the same time, due to the improved flatness of the cut surface, the subsequent installation process is smoother, reducing installation time and improving the overall efficiency of the engineering operation.

[0030] like Figure 2As shown, the clamping structure includes a fixed splint 41, a movable splint 42 and a fixing member. The movable splint 42 is arranged relative to the fixed splint 41 to form a clamping space therebetween. The fixed splint 41 is fixed and stationary, and the movable splint 42 is arranged to be movable relative to the fixed splint 41. When the movable splint 42 moves into position, the movable splint 42 is fixed to the cutting seat by the fixing member. By adjusting the distance between the movable splint 42 and the fixed splint 41, the size of the clamping space is controlled, and it can be applied to anchor rods to be cut of different sizes, ensuring stable clamping of anchor rods of different sizes and enhancing the versatility of the device. After the anchor rod to be cut is placed in the clamping space, the movable splint 42 can be operated to move toward the fixed splint 41 until the fixed splint 41 and the movable splint 42 clamp the anchor rod to be cut, and then the position of the movable splint 42 is fixed by the fixing member. When the cut anchor rod needs to be taken out, the movable splint 42 is released from the limited state by adjusting the fixing piece, and then the movable splint 42 is adjusted away from the fixed splint 41, thereby expanding the clamping space and allowing the cut anchor rod to be taken out.

[0031] Specifically, the cutting seat also includes a base plate 21, which is connected to the platform structure 10 via the base plate 21. The guide plate 22 and the clamping plate 23 are located on the side surface of the base plate 21 facing away from the platform structure 10, and the guide plate 22 and the clamping plate 23 are vertically arranged on the base plate 21, that is, the guide plate 22 is perpendicular to the base plate 21, and the clamping plate 23 is perpendicular to the base plate 21. The fixed clamping plate 41 and the movable clamping plate 42 are also vertically arranged on the base plate 21. The base plate 21 has a sliding groove 211, which is elongated and located on the side of the clamping plate 23 away from the guide plate 22. The extension direction of the elongated sliding groove 211 is the same as the extension direction of the cutting head 31. The movable clamping plate 42 is movably arranged on the sliding groove 211 along the extension direction of the sliding groove 211. The design of the sliding groove 211 enables the moving clamping plate 42 to move smoothly. By adjusting the moving position of the moving clamping plate 42 on the sliding groove 211, the size of the clamping space is adjusted, thereby improving the convenience of operation.

[0032] like Figure 2 As shown, the moving splint 42 has two oppositely arranged plate sections on the side facing away from the fixed splint 41. The two plate sections are parallel to the base plate 21. Guide pin holes 421 are correspondingly provided on the two plate sections. The projections of the guide pin holes 421 on the two plate sections on each other coincide with each other, and the projections of the guide pin holes 421 on the base plate 21 are located in the sliding groove 211.

[0033] Specifically, the fixing member includes a fixed guide pin 43, a nut seat 44, an operating rod, a bottom gasket 46, and a bottom bolt 47. A limiting hole 431 is provided on the side wall of the fixed guide pin 43; the nut seat 44 and the base plate 21 each have corresponding screw holes, and a bolt is passed through the screw holes on the nut seat 44 and the base plate 21 to achieve a fixed connection between the two. The nut seat 44 is located on the side of the moving splint 42 away from the fixed splint 41. Specifically, the nut seat 44 is spaced apart from the end of the sliding groove 211 on the side away from the fixed splint 41. The nut seat 44 has a threaded hole, the extension direction of which is perpendicular to the center line connecting the two guide pin holes 421, and the extension direction of the threaded hole is the same as the extension direction of the sliding groove 211. The operating rod consists of a threaded rod 451 and a handwheel 452 that are connected to each other. The outer wall of the threaded rod 451 has a threaded section that cooperates with the threaded hole so that the threaded rod 451 can cooperate with the threaded hole. The end of the threaded rod 451 passes through the threaded hole and extends toward the moving splint 42. The protruding end of the threaded rod 451 is a screw tail pin 4511. The handwheel 452 is connected to the end of the threaded rod 451 on one side away from the moving splint 42. By turning the handwheel 452, the screw tail pin 4511 can be adjusted to move toward the moving splint 42 or away from the moving splint 42.

[0034] In addition, the end of the fixed guide pin 43 passes through the two guide pin holes 421 and the sliding groove 211 in sequence and extends from the sliding groove 211 to the side of the base plate 21 facing the platform structure 10. At this time, the fixed guide pin 43 can be slid along the extension direction of the sliding groove 211, and the limiting hole 431 on the fixed guide pin 43 is between the two plate sections. The fixing part also includes a bottom gasket 46 and a bottom bolt 47. When the moving splint 42 moves into place, the protruding end of the fixed guide pin 43 is limited to the side of the base plate 21 facing the platform structure 10 by the bottom gasket 46 and the bottom bolt 47, and the end of the threaded rod 451 extends between the two plate sections and is connected to the limiting hole 431.

[0035] Specifically, when the moving splint 42 slides to the desired position, by turning the handwheel 452, the screw tail pin 4511 of the threaded rod 451 is adjusted to extend between the two plate sections and into the limiting hole 431, and connected to the stopper of the limiting hole 431, thereby limiting the fixed guide pin 43 to the desired position, and the bottom gasket 46 is mounted on the protruding end of the fixed guide pin 43 and makes the bottom gasket 46 fit with the surface of the side of the bottom plate 21 facing the platform structure 10, and then the bottom bolt 47 is screwed into the end of the fixed guide pin 43, thereby keeping the end of the fixed guide pin 43 on the side of the bottom plate 21 facing the platform structure 10, preventing the fixed guide pin 43 from moving up and down and sliding along the sliding groove 211, thereby limiting the moving splint 42.

[0036] During actual operation, mark the place on the anchor rod that needs to be cut, place it in the slot 231, and align the mark exposed in the slot 231 with the edge of the slot 231. At least a part of the anchor rod is clamped and fixed by the clamping structure so that the anchor rod maintains a certain level. Turn the handwheel 452 clockwise to rotate the threaded rod 451 so that the screw tail pin 4511, the fixed guide pin 43 and the moving splint 42 are constantly close to the fixed splint 41, thereby pressing the anchor rod, and then the anchor rod exposed in the slot 231 is squeezed and sheared by the cutting structure to cut it off.

[0037] like Figure 1 As shown, the cutting structure also includes a telescopic part, one end of the telescopic part is connected to the platform structure 10 through a first fastener, and the other end of the telescopic part is connected to the cutting head 31 through a second fastener. Specifically, two relatively arranged fixed plates 11 are vertically arranged on the mounting surface, and both fixed plates 11 are provided with through holes. One end of the telescopic part has an ear seat, and the ear seat has a through hole. The ear seat of the telescopic part is accommodated between the two fixed plates 11, and the through holes on the two fixed plates 11 are aligned with the through holes of the ear seat, and then the first fastener is passed through the through hole to realize the fixed connection between the fixed plate 11 and the ear seat. The first fastener is a bolt or a connecting pin, which can be selected according to actual conditions. This arrangement allows the telescopic part to extend and retract, thereby driving the cutting head 31 to perform telescopic movement. By rationally planning the connection method, it is helpful to reduce vibration during the cutting process and improve the cutting accuracy.

[0038] Specifically, the telescopic portion is parallel to the platform structure 10, and the central axis of the telescopic portion coincides with the centerline of the cut head 31. In other words, the telescopic portion's telescopic direction is the same as the extension direction of the cut head 31. The telescopic portion has a protrusion 321 at the end facing the cut head 31, and the cut head 31 has a recessed portion 311 that cooperates with the protrusion 321. The protrusion 321 and the recessed portion 311 have corresponding through-holes. During installation, the protrusion 321 is installed in the recessed portion 311 to achieve a fit between the two. Then, a second fastener is inserted through the through-holes of the two to secure the protrusion 321 in the recessed portion 311. The protrusion 321 of the telescopic portion can be understood as a plate-like structure extending from the center of the end of the telescopic portion, and the recessed portion 311 is specifically a groove. When the protrusion 321 is installed in the recessed portion 311, a portion of the outer wall of the protrusion 321 can be observed. Optionally, the second fastener is a bolt or a connecting pin, which can be set according to actual circumstances. This connection method not only ensures a firm connection between the telescopic portion and the cutting head 31, but also facilitates disassembly and maintenance, thereby improving the durability and maintenance efficiency of the device.

[0039] like Figure 1As shown, the telescopic portion includes a piston rod 32 and a cylinder body 33. The piston rod 32 is telescopically arranged in the cylinder body 33. The portion of the piston rod 32 extending from the cylinder body 33 is connected to the cutting head 31. An oil inlet 331 and an oil outlet 332 are provided on the outer wall of the cylinder body 33. The oil inlet 331 and the oil outlet 332 are connected to the internal space of the cylinder body 33. In a specific embodiment of the present application, the telescopic portion is a hydraulic telescopic portion, specifically a hydraulic jack. The power of the telescopic portion comes from the emulsion pump station. The oil inlet 331 and the oil outlet 332 are connected to the operating valve group through a hydraulic pipeline. The operating valve group is then connected to the liquid supply pipeline of the emulsion pump station to form a circuit. The expansion and contraction of the piston rod 32 and the cutting head 31 are controlled by the operating valve group handle. The hydraulically driven telescopic portion can provide powerful power to ensure the rapid cutting of the anchor rod. At the same time, the expansion and contraction control of the piston rod 32 is more precise, improving the safety and efficiency of the operation. The hydraulic drive not only provides sufficient power, but also allows the operator to accurately adjust the extension and retraction speed and force of the cutting head 31 through the control valve, ensuring the controllability and safety of the cutting process.

[0040] like Figure 1 As shown, the guide plate 22 and the clamping plate 23 are placed upright on the base plate 21, and the guide plate 22 is arranged perpendicular to the cutting head 31. The guide plate 22 is vertically connected to the clamping plate 23. The clamping groove 231 is a U-shaped groove. The opening side of the U-shaped groove is located on the side of the clamping plate 23 away from the base plate 21, that is, the opening direction of the U-shaped groove is set upward. The guide plate 22, the clamping plate 23 and the base plate 21 can be connected by welding. The groove wall surface of the U-shaped groove is flush with the surface of the side of the guide plate 22 away from the cutting structure. The design of the U-shaped groove can better adapt to the shape of the anchor rod, ensure the stable clamping of the anchor rod during the cutting process, and avoid inaccurate cutting caused by the shaking of the anchor rod. At the same time, it is convenient to quickly install the anchor rod on the U-shaped groove or take it out of the U-shaped groove, which is easy to operate.

[0041] Specifically, the cutting head 31 comprises a guide surface 312, a cutting surface 313, and a connecting surface 314. The guide surface 312, cutting surface 313, and connecting surface 314 are sequentially connected at an angle. The guide surface 312 and cutting surface 313 are connected at an acute angle, forming a cutting edge at their junction. The guide surface 312 is parallel to the direction of extension and contraction of the cutting head 31. The guide surface 312 and connecting surface 314 are parallel and opposite each other. The area of ​​the cutting surface 313 is smaller than that of the guide surface 312, and the area of ​​the cutting surface 313 is smaller than that of the connecting surface 314. The cutting head 31 is fabricated from automotive steel sheet. The cutting surface 313 is an inclined surface, and the angle between the guide surface 312 and the cutting surface 313 is approximately 45°. The cutting head 31 is quenched to enhance its hardness. By rationally designing the structure of the cutting head 31 and adjusting the angle between the cutting surface 313 and the guide surface 312, not only is cutting efficiency improved, but also sparks and noise during the cutting process are reduced, improving operational safety and environmental friendliness. At the same time, the structural strength of the cutting head 31 can be guaranteed, and the service life of the cutting head 31 can be guaranteed. The cutting head 31 can complete the cutting task more quickly and accurately, and the cutting efficiency is guaranteed.

[0042] Specifically, when the cutting head 31 is extended, it can move within the guide hole 221. The height of the cutting head 31 matches the height of the guide hole 221, and the maximum extension stroke is greater than the distance from the exit of the guide hole 221 to the side arm of the retaining slot 231 away from the guide plate 22. Furthermore, the height of the cutting head 31 is greater than the diameter of the anchor rod, and the height of the guide hole 221 is greater than or equal to the diameter or height of the anchor rod when placed in the retaining slot 231. The centerline of the guide hole 221 is perpendicular to the centerline of the retaining slot 231, and the centerline of the retaining slot 231 is perpendicular to the retaining slot 231, but not the axis of symmetry.

[0043] The anchor rod cutting device of the present application drives the cutting head 31 to slide and retract in the guide through hole 221 by controlling the telescopic movement of the telescopic part, and squeezes and shears the anchor rod exposed on the edge of the slot 231 to cut it off. It is reliable for personnel to operate and easy to use. At the same time, it greatly reduces the labor intensity of operators, prevents the abandoned anchor rods in the comprehensive mining working face from being improperly handled, resulting in the loaded anchor rods being too long, too wide, and too high, causing electromechanical transportation accidents such as transport vehicles falling and cables leaking, and ensures safe production in coal mines.
