Description

Technical Field

[0001] The utility model relates to the field of mine support tools, in particular to a tool for fastening resin anchor nuts. Background Art

[0002] In underground mine construction, in order to ensure the safety and stability of the working area, bolt support technology is usually used to reinforce the surrounding rock. Among them, resin bolts are a widely used support material, which provides anchoring force to support the formation pressure by inserting the bolts into pre-drilled holes and curing them with the help of resin bags.

[0003] During the anchor bolt construction process, workers need to tighten the nut at the tail of the resin anchor bolt to complete the anchor bolt fixation. In the actual operation environment of the mine, the anchor bolts are distributed throughout the entire section. Especially when tightening the nuts at higher positions such as the roof of the underground tunnel, workers often need to build a support for high-altitude operations and need to climb up and down repeatedly, which not only increases the labor intensity, but also greatly reduces the work efficiency, and there is also a safety risk of falling.

DETAILED DESCRIPTION

[0022] The technical solution of the utility model is described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Embodiment 1

[0023] like Figure 1 As shown, it is used when constructing resin anchors at higher positions of top plates, arch corners and side walls, and the extension sleeve 1, the extension component 2 and the wrench 3 are used in combination.

[0024] like Figure 2 As shown, the front end of the extended sleeve 1 is provided with a first hexagonal hole 1-1, and the first hexagonal hole 1-1 is used to cooperate with the anchor nut.

[0025] like Figure 3 , 4 As shown in Figures 5 and 6, the extension assembly 2 includes an extension rod 2-2, one end of which is provided with a second external hexagon 2-3, and the other end of which is provided with an external thread 2-1. The wrench 3 is provided with a second hexagon hole 3-4, which cooperates with the second external hexagon 2-3 of the extension rod 2-2 and the external thread 2-1 of the extension rod 2-2; the second external hexagon 2-3 of the extension rod 2-2 is consistent with the specifications of the anchor nut.

[0026] like Figure 5 As shown, a ratchet 3-1 is rotatably mounted on the handle 3-3 of the wrench 3, a second hexagonal hole 3-4 is provided on the ratchet 3-1, a groove is provided on the handle 3-3 of the wrench 3, an elastic component 3-2 (spring) is installed at the end of the groove away from the ratchet 3-1, and a limit device 3-5 (with a wedge-shaped stopper at the outer end) is installed at the end close to the ratchet 3-1 by sliding fit, and the outer end of the limit device 3-5 is clamped on the pawl of the ratchet 3-1. When tightening the anchor nut, Figure 5 The ratchet 3-1 has a tendency to rotate clockwise relative to the handle 3-3. At this time, the limit device 3-5 blocks the ratchet 3-1 so that it cannot rotate. When the wrench 3 returns, Figure 5 The ratchet 3-1 has a tendency to rotate counterclockwise relative to the handle 3-3. At this time, the ratchet 3-1 pushes the limit device 3-5 and can rotate freely, so there is no need to disengage the tool from the anchor nut during the return stroke.

[0027] When in use, the spanner 3 is vertically connected to one end of the extension rod 2-2, and the second outer hexagonal hole at one end of the extension rod 2-2 is connected to the first hexagonal hole fixedly connected to the tail of the extension sleeve 1. The combined tool can be used to tighten the resin anchor nut; the threaded hole 2-4 in the second outer hexagonal hole at one end of the extension rod 2-2 is matched with the outer thread 2-1 at the other end. Multiple extension rods can be connected end to end to form a new extension assembly according to the required length, and then combined with the spanner 3 and the extension sleeve 1 for use. In this way, when tightening the anchor rod at a higher place, there is no need to set up a bracket and repeatedly climb the operation, and the operator can easily complete the tightening operation. Embodiment 2

[0028] like Figure 3 As shown, the rear end of the extended sleeve 1 also has a first external hexagon 1-5, in which the first threaded hole 1-3 is arranged, and the first external hexagon 1-5 is used to cooperate with the second hexagon hole 3-4 of the wrench 3. The first external hexagon 1-5 at the rear end of the extended sleeve 1 is consistent with the specifications of the anchor nut.

[0029] like Figure 2 As shown, when the resin anchor is constructed at a flat or concave position of the wall, the wrench 3 is connected to the extension sleeve 1 to tighten the resin anchor nut. Embodiment 3

[0030] When the resin anchor is constructed at the protruding position of the wall, the second hexagonal hole 3-4 of the wrench 3 can be directly buckled onto the resin anchor nut for tightening.

[0031] It should be noted that it is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. The scope of the present invention is defined by the claims rather than the above description.
