Description

Technical Field

[0001] The utility model relates to the technical field of cutting auxiliary tools, and more specifically, to an anchor cable cutting protector. Background Art

[0002] As an effective way of roadway support, anchor cable support can significantly improve the stability of surrounding rock due to its strengthening effect on the strength of roadway surrounding rock. In addition, it has the advantages of low support cost, fast roadway construction speed, reduced labor intensity, improved roadway section utilization, simplified mining face end maintenance process, and significantly improved working environment and safe production conditions. It can improve the economic benefits of mines and has become a major support form for coal mine enterprise roadways, representing the main development direction of coal mine roadway support technology.

[0003] During maintenance work on the main tunnel, the anchor cables are exposed too long after the expansion, so they need to be shortened uniformly. During the process of cutting the anchor cables, there is a risk of the anchor cable heads flying and injuring people.

[0004] The utility model patent with patent publication number CN207386431U discloses an anchor cable cutting guide device, which relates to the field of mechanical processing, including a base, a turntable and a guide device. The base is placed on the ground, and a fixed shaft is provided in the middle. A through hole is opened in the middle of the turntable, and the through hole of the turntable is matched and connected with the fixed shaft so that the turntable rotates on the base. The base is extended with a bracket, and a guide device is provided on the bracket. The guide device includes a vertical limiting device installed at one end of the bracket, and a horizontal limiting device installed on the bracket and located behind the vertical limiting device. The vertical limiting device has a pair of vertical guide rollers, and a limiting cavity is formed in the middle of the pair of vertical guide rollers for the anchor cable to pass through. The horizontal guide limiting device is a horizontal guide roller. The utility model limits one end of the anchor cable through the limiting device, and then cuts it, which reduces labor intensity, eliminates safety hazards, and improves cutting efficiency.

[0005] However, when this structure is actually used, first, before cutting the anchor cable, one end of the anchor cable needs to be passed through the vertical limit device. For a longer anchor cable, the passing process is cumbersome and inconvenient to use. In addition, the anchor cable is wound up by multiple support rods on the turntable. Due to the high strength and toughness of the anchor cable, there is a risk that the wound anchor cable will pop out and detach from the support rod after cutting. Therefore, an anchor cable cutting protector is proposed. Utility Model Content

[0006] In order to overcome the above defects of the prior art, the utility model provides an anchor cable cutting protector to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anchor cable cutting protector, comprising a bottom support plate, an upper pressure plate hinged at the top of the bottom support plate, a pull rod movably connected to the middle of one side of the upper pressure plate, a screw rod rotatably connected to the middle of the bottom end of the bottom support plate, a hand-held rod fixedly connected to the bottom end of the screw rod, a hand wheel installed at the bottom end of the hand-held rod, a sliding sleeve sleeved on the screw rod, and the sliding sleeve is connected and cooperated with the pull rod.

[0008] By opening the bottom support plate, the anchor cable is directly clamped in the clamping groove opened between the bottom support plate and the upper pressure plate, and then the bottom end of the pull rod is clamped in the clamping groove set on the sliding sleeve, and then the outside of the pull rod is blocked by the stop pin. The operator can directly rotate the screw rod by turning the handwheel at the bottom of the handheld rod, so that the sliding sleeve pulls the pull rod down, so that the bottom support plate clamps and fixes the anchor cable between the upper pressure plate. After fixing, when cutting the anchor cable, only one operator is required to cut the anchor cable from the cutting groove, and the other operator holds the handheld rod to cooperate to cut. After the anchor cable is cut, the two ends of the cut are still fixed, so as to avoid the phenomenon of flying collapse, thereby improving safety. After cutting, the handwheel is directly turned to loosen the anchor cable for direct separation.

[0009] Preferably, the fitting surfaces of the bottom support plate and the upper pressure plate are both provided with clamping grooves, and the inner wall of each clamping groove is provided with anti-slip grooves.

[0010] Preferably, a notch is provided on one side of the middle portion of the bottom support plate and the upper pressure plate, and the two notches are connected and matched to form a cutting groove.

[0011] Preferably, a connecting frame is welded to one side of the upper pressing plate, and the top end of the pull rod is hinged in the connecting frame.

[0012] Preferably, a shaft seat is installed at the top end of the screw rod, and the shaft seat is connected to a bottom support plate.

[0013] Preferably, a slot is provided on one side of the sliding sleeve, a stop pin is provided in the slot, two locking nuts are installed at the bottom end of the pull rod, the two locking nuts are respectively provided at the upper and lower ends of the slot, and the stop pin is screwed on one side of the pull rod.

[0015] Technical effects and advantages of the utility model:

[0016] 1. Compared with the prior art, the bottom support plate, the upper pressure plate, the pull rod, the screw rod and the sliding sleeve are arranged. The two ends of the anchor cable cutting position are clamped and fixed by the bottom support plate and the upper pressure plate, and the pull rod and the sliding sleeve are connected and fixed. When cutting the anchor cable, it is only necessary to clamp the protector at the cutting position. The operation is convenient and simple to use. The anchor cables of different lengths can be quickly matched and used, and the cutting efficiency of the anchor cable is improved. After cutting, the cut anchor cable can be fixed, thereby avoiding flying collapse and separation, and further improving the safety of use.

[0017] 2. Through the arrangement of the shaft seat, the screw rod, the hand-held rod, the hand-wheel and the pull rod, compared with the prior art, the hand-held rod can be used to clamp and lift anchor cables of different heights, and the clamping strength of the clamping end can be adjusted from the bottom. At the same time, after cutting, the bottom support plate and the upper pressure plate can be separated directly by turning the hand wheel, and the protector can be directly separated from the anchor cable, thereby improving the convenience and practicality of use.
