Description

Technical Field

[0001] The utility model relates to the technical field of wrenches, in particular to a fixed-distance wrench for disassembling a drill rod. Background Art

[0002] The drill rods used for drilling anchor (cable) holes at the top of the underground coal mine excavation working face are generally B19, B22 or B25 types. This series of drill rods are hexagonal hollow cylinders as a whole. In the actual construction process, different numbers of drill rods need to be connected end to end according to the drilling depth. When removing the drill rods after drilling, two adjustable wrenches are required for disassembly. First, the two adjustable wrenches need to be tightened to the same width as the drill rods, and then the two wrenches are clamped on adjacent drill rods for disassembly. In this process, the wrench clamps are often too tight to be inserted into the drill rod or the clamps are too loose, resulting in slipping during the disassembly process, which is inconvenient to use.

[0003] The above problems can be solved by using a fixed-distance fixed-end wrench. However, the fixed-end wrench will inevitably produce wear and deformation at the clamping point during use. After long-term accumulation, it will become difficult to clamp the drill pipe. It needs to be purchased and replaced regularly, which incurs certain expenses and is not conducive to controlling the overall operating costs of the enterprise.

[0004] To this end, the present application specifically proposes a distance wrench for disassembling a drill rod to solve the above technical problems. Utility Model Content

[0026] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0027] like Figure 1-7 As shown, the utility model provides a distance wrench for disassembling a drill rod, comprising:

[0028] The handle 1 is made by cutting a discarded drill rod 3;

[0029] The chuck 2 is detachably arranged at one end of the handle 1 and is used to clamp the drill rod 3. The chuck 2 includes a connecting rod 21 for connecting to the handle 1 and a clamping rod 22 symmetrically welded on both sides of the connecting rod 21. The connecting rod 21 and the clamping rod 22 are made by cutting scrapped drill rods 3.

[0030] The main structures of the handle 1 and the chuck 2 are cut from the scrapped drill rod 3, which greatly reduces the manufacturing cost. Figure 1 and Figure 2 As shown, when in use, the operator holds the handle 1 and clamps the drill rod 3 in the gap between the two clamping rods 22, and then rotates the two handles 1 in opposite directions to realize the disassembly of the adjacent drill rods 3.

[0031] In one embodiment, the handle 1, the connecting rod 21 and the clamping rod 22 are cut from the same model of the drill rod 3, and the clamping rod 22 has six outer side surfaces, one of which is in contact with the outer side surface of the connecting rod 21 and the edges are aligned. In this design, the distance between the two clamping rods 22 is equal to the distance between the two opposite surfaces of the connecting rod 21, and the cross-sectional size of the connecting rod 21 is the same as that of the drill rod 3, so the drill rod 3 can just fit into the gap between the two clamping rods 22, ensuring that the clamping head 2 can clamp the drill rod 3.

[0032] In one embodiment, the clamping rod 22 is partially welded and fixed on the connecting rod 21, and the length of the clamping rod 22 extending from the connecting rod 21 is greater than the rotation diameter of the drill rod 3. This design ensures that when the drill rod 3 is clamped into the clamping head 2, the opposite surfaces of the two clamping rods 22 can fully contact the drill rod 3, thereby improving the stability of use.

[0033] In one embodiment, the connecting rod 21 is cut from both ends of the drill rod 3, and one end of the connecting rod 21 having the stud 4 is used as the connecting end, and one end of the handle 1 is provided with a screw hole 5 that matches the stud 4. Since both ends of the drill rod 3 have the stud 4, and the stud 4 can be used as the connecting part of the connecting rod 21, in this design, it is only necessary to open the screw hole 5 that matches the stud 4 at one end of the handle 1 to achieve threaded matching between the connecting rod 21 and the handle 1. When the clamping rod 22 is worn or deformed seriously due to long-term use, the clamping head 2 can be replaced as a whole without replacing the entire wrench, thereby reducing the use cost.

[0034] In one embodiment, an anti-slip assembly 9 is further included, which is fixedly mounted on the clamp head 2. The anti-slip assembly 9 includes support rods 91 symmetrically mounted on both sides of the connecting rod 21, a hook 92 movably inserted at one end of the support rod 91, and a spring 93 symmetrically mounted on both sides of the hook 92. One end of the spring 93 is hinged on the support rod 91 and the other end is hinged on the hook 92. Figure 5 As shown, when using a wrench to clamp the drill rod 3, firstly, the bottom of the clamp head 2 and the inner side of the hook 92 are simultaneously abutted against the drill rod 3, and it is necessary to ensure that the clamping rod 22 and the drill rod 3 are in surface-to-surface contact, rather than surface-to-edge or edge-to-edge contact. In this case, the clamp head 2 cannot directly clamp the drill rod 3. Figure 6 As shown, the handle 1 is then pulled to extend the hook 92 from the support rod 91. At this time, the spring 93 is stretched by the tension, and a gap appears between the end of the chuck 2 and the drill rod 3. The handle 1 is moved to make the drill rod 3 fit into the chuck 2 and the hook 92 at the same time. The spring 93 contracts and presses the drill rod 3 between the chuck 2 and the hook 92, so that the drill rod 3 is in a three-point clamping state. In this way, when the handle 1 is turned to disassemble the drill rod 3, the wrench is difficult to slip off the drill rod 3, thereby improving the stability of use.

[0035] In one embodiment, the hook 92 is L-shaped as a whole and a slot 10 for clamping the drill rod 3 is provided at the inner corner. With this design, when the anti-slip assembly 9 cooperates with the clamp head 2 to clamp the drill rod 3, the drill rod 3 can be clamped into the slot 10, thereby improving the fit between the drill rod 3 and the inner wall of the hook 92, thereby further improving the stability of clamping.

[0036] In one embodiment, a nut 6 is welded to the other end of the handle 1, and a hanging ring 7 is passed through the nut 6. By providing the hanging ring 7 on the handle 1, the wrench can be hung on the rack, which is convenient for storing the wrench. The handle 1 is cut from the drill rod 3, and there is no ready-made hole at the end for the hanging ring 7 to pass through. Compared with drilling a hole at the end of the handle 1, welding the nut 6 and using its threaded hole as a hole for the hanging ring 7 to pass through is a solution that is easier to process.

[0037] In one embodiment, a grip 8 is evenly wound on the outer wall of the handle 1. This design can optimize the grip feel of the handle 1 and increase the friction coefficient of the outer wall of the handle 1 to prevent the operator from easily slipping out of the handle 1 when turning it.

[0038] It is obvious 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 present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.

[0039] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0040] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.
