Description

Technical Field

[0001] The utility model relates to the field of blasting deep hole slope measurement, in particular to a blasting deep hole slope measurement device in a coal mine. Background Art

[0002] When a coal mine working face encounters hard rock structures such as faults or sinkholes, deep hole pre-splitting blasting technology is often used to weaken them to facilitate the rapid passage of coal cutters and achieve the engineering goal of quickly, safely and economically passing through hard rock formations. However, when the depth of blastholes in hard rock formations is deep (usually tens of meters), the actual blasthole angle often does not match the blasting design, resulting in the explosives not exploding within the expected blasting implementation range, thus failing to truly achieve the engineering purpose. For this reason, after drilling and before charging, it is necessary to clarify the position of the charging section and measure the deflection of the deep hole in the vertical direction.

[0003] At present, deep holes are usually measured using deep hole inclinometers. Most existing deep hole inclinometers are composed of an inclinometer reader, a cable and an inclinometer rod. When in use, both ends of the cable need to be connected and fixed with the inclinometer reader and the inclinometer rod, and then the inclinometer rod is placed in the blasting deep hole. The cable is then moved to move the inclinometer rod downward into the blasting deep hole. However, the cable will drag on the ground during the movement, which will not only cause the cable to be tangled in a disorderly manner, but also easily wear out. If it needs to be dragged off the ground, the cable is mostly picked up manually, which is time-consuming and laborious.

[0004] Therefore, it is necessary to invent a device for measuring the slope of a deep hole for underground blasting in a coal mine. Utility Model Content

[0005] The purpose of the utility model is to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a coal mine underground blasting deep hole inclination measuring device, comprising a winding roller and a cable, the cable is wound around the outside of the winding roller, one end of the cable is connected to an inclinometer rod, fixed seats are symmetrically installed on both sides of the upper end of the winding roller, a V-shaped groove is provided in the middle of the upper end of the fixed seat, a fixing assembly is installed on the upper end of the fixed seat, a connecting assembly is installed on one side of the fixed seat, and a supporting assembly is installed on the side of the connecting assembly away from the fixed seat.

[0007] Based on the above characteristics: when measurement is not required, excess cables will be wound around the outside of the winding roller to prevent the cables from being entangled in a disorderly manner, and the inclinometer rod will be placed on the inner side of the V-groove to limit the position. At this time, the fixed seat can support the inclinometer rod, and the fixed assembly can limit the upper end of the V-groove to prevent the inclinometer rod from detaching from the V-groove by itself. When measurement is required, the fixed assembly can be released, and then the inclinometer rod can be taken out of the V-groove. Then the connecting assembly can drive the supporting assembly to move so that the supporting assembly moves to the top of the blasting deep hole. Finally, the inclinometer rod can be inserted vertically downward into the blasting deep hole, and the winding roller will also release the cable synchronously. At this time, the supporting assembly can suspend and support the cable, which will not cause the cable to be dragged on the ground and cause wear, and there is no need for personnel to pick up the cable.

[0008] Preferably, a positioning plate is fixedly mounted on one side of the upper end of the fixing seat away from the connecting assembly, and a magnet is mounted on the other upper end of the fixing seat.

[0009] Based on the above features: the positioning plate can be connected and fixed to one side of the fixed component. When the fixed component is rotated to the top of the V-shaped groove, the magnet can adsorb and fix the fixed component to prevent the fixed component from detaching from the top of the V-shaped groove.

[0010] Preferably, the fixing assembly includes a limiting plate and a magnetic block installed on one side of the limiting plate, a fixing nut is installed in the middle of the limiting plate, and a locking screw is threadedly connected in the middle of the fixing nut.

[0011] Based on the above features: when the limit plate rotates to the top of the V-groove, the magnetic block will attract the magnet and fix it, and at the same time, the locking screw can be rotated to move the locking screw downward and press against the upper ends of both sides of the inclinometer rod. When the locking screw does not rotate, the fixing nut will lock the locking screw.

[0012] Preferably, the connecting assembly includes a connecting plate and a base fixedly mounted at the lower end of the connecting plate, and a telescopic cylinder is installed in the inner cavity of the base.

[0013] Based on the above features: the piston rod of the telescopic cylinder can extend out of the base, so as to facilitate the movement of the support assembly, so that the support assembly moves to the top of the blasting deep hole.

[0014] Preferably, a through hole is opened on one side surface of the connecting plate and the base, a connecting rod is movably connected to the inner cavity of the connecting plate, an anti-detachment baffle is fixedly installed on one side of the connecting rod, and the anti-detachment baffle is located in the inner cavity of the connecting plate.

[0015] Based on the above features: one side of the connecting rod is connected and fixed to the supporting assembly, when the telescopic cylinder pushes the supporting assembly to move, the connecting rod will also move synchronously, and the anti-detachment baffle is set to prevent the connecting rod from detaching from the connecting plate.

[0016] Preferably, the support assembly includes a support seat and a bearing installed in the middle of the support seat, a support rod is installed in the middle of the bearing, and a roller is sleeved on the outside of the support rod.

[0017] Based on the above characteristics: the support rod and the roller can rotate in the middle of the support through the bearing. When the cable is laid on the outside of the roller, the support rod and the roller will also rotate as the cable moves, so that rolling friction is formed between the cable and the roller to avoid damage to the cable.

[0018] Preferably, a convex plate is fixedly mounted on the lower end of the support.

[0019] Based on the above features: one end of the connecting rod is connected and fixed to the convex plate, so that when the support moves, the convex plate can be used to pull the connecting rod to move synchronously, thereby avoiding separation of the supporting component and the connecting component.

[0020] The beneficial effects of the utility model are:

[0021] 1. It is not only convenient to support and suspend the cable, but also can prevent the cable from being dragged on the ground and caused by wear. When measurement is not needed, the inclinometer rod is placed on the inside of the V-groove. At this time, the fixed seat can support the inclinometer rod. When measurement is needed, the fixing assembly can be released and the inclinometer rod can be taken out from the inside of the V-groove. Then the connecting assembly can drive the support assembly to move so that the support assembly moves to the top of the blasting deep hole. Finally, the inclinometer rod can be inserted vertically downward into the blasting deep hole, and the winding roller will also release the cable synchronously. At this time, the support assembly can suspend and support the cable, and will not cause the cable to be dragged on the ground and cause wear. At the same time, there is no need for personnel to pick up the cable. As the cable moves, the support rod and the roller will also rotate, so that rolling friction is formed between the cable and the roller to avoid damage to the cable.

[0022] 2. To improve the limiting fixing effect, when the inclinometer rod is fixed inside the V-groove, rotate the limiting plate to the top of the V-groove. At this time, the magnetic block will absorb the magnet to fix it, preventing the limiting plate from detaching from the top of the V-groove. At the same time, you can rotate the locking screw to move the locking screw downward and press against the upper ends of both sides of the inclinometer rod to prevent the inclinometer rod from detaching from the V-groove.
