Description

Technical Field

[0001] The utility model relates to the field of mining, blasting environmental protection, anti-blocking and dust prevention, and in particular to a drilling hole protection cover. Background Art

[0002] Mineral resource mining refers to the mining of solid metal and non-metallic deposits, including open-pit mining of surface ore outcrops and shallow ore bodies, and underground mining of blind mines and deep ore bodies. When mining in open-pit mines, it is necessary to drill holes in the rock. Drilling equipment refers to the use of tools that are harder and sharper than the target object through rotary cutting or rotary extrusion to leave cylindrical holes or holes in the target object. Drilling equipment plays a very important role in industrial production.

[0003] Down-the-hole rock drills are used in open-pit mining, drilling rock blasting holes and construction. When drilling holes on flat ground, down-the-hole rock drills will leave a conical rock powder ash pile on the ground. The drill hole is located below the bottom center of the conical rock powder ash pile. Therefore, if the drill hole is not used immediately, it is very easy to cause problems such as rain erosion, water accumulation in the hole, collapse of the slag pile to bury the drill hole, and dust from the slag pile under windy conditions.

[0004] In order to protect the drill holes, most mine workers cover the ash piles with nylon bags or other films, and use local materials to press the edges of the nylon bags or other films with part of the ash. However, although the problem of protecting the holes is solved after covering with nylon bags or other films, the ash used to press the bags will cause dust when the wind blows. The dust phenomenon has a great impact on the environment, which is extremely inconsistent with the current environmental protection situation that is strongly advocated.

[0005] In view of this, we propose a drilling hole protection cover. Utility Model Content

[0006] The utility model aims to provide a hole protection cover for protecting drill holes in open-pit mines, so as to solve the problems raised in the above-mentioned background technology.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A drilling hole protection cover comprises a covering group, wherein the covering group comprises a cover body for covering an ash pile, wherein a hanging group for temporarily closing a hole below the bottom center of the ash pile is arranged in the cover body.

[0009] As a further solution of the utility model: the hanging group includes a hook and a gravity ball, a hanging ring is provided on the top of the gravity ball, and a connecting rope is provided between the hanging ring of the gravity ball and the hook.

[0010] As a further solution of the utility model: a fixing rod with rings at both ends is provided at the center of the cover body, and a label slot for recording information is provided on the surface of the cover body.

[0011] As a further solution of the utility model: the hook is hung in the ring at one end of the fixed rod, and the gravity ball falls vertically into the hole below the center of the bottom of the ash pile through the connecting rope.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. In the drilling hole protection cover, you only need to hang the dust cover on the gravity ball. After the gravity ball is placed in the hole, the dust cover is covered on the ash pile, and the dust cover is rotated to fit tightly with the surface of the ash pile. All work processes can be completed. The operation is simple and the occurrence of drilling blockage is reduced.

[0014] 2. In the drilling hole protection cover, the dust cover is subjected to the downward gravity of the gravity ball and forms a conical shape with a diversion effect after being attached to the surface of the ash pile, so that the ash pile around the top of the drilling hole is not easily blown by the wind, reducing the occurrence of dust from the ash pile.

[0015] 3. In the drilling hole protection cover, the dust cover and the gravity ball can be customized in batches according to the actual site and reused to save costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in 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. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1As shown, this embodiment provides a drilling hole protection cover, including a covering group 100, the covering group 100 includes a cover body 101, the cover body 101 is used to cover the ash pile, a detachable hanging group 110 is fixed in the cover body 101, and the hole below the bottom center of the ash pile is temporarily closed by the hanging group 110.

[0023] The improvement of this embodiment is that by hanging a suspension group 110 in the dust cover, placing the gravity ball 113 in the suspension group 110 in the hole, the dust cover is covered on the ash pile by rotating so that the dust cover fits tightly against the surface of the ash pile, and all work processes can be completed. The operation is simple and the blockage of the drilling hole is reduced. The dust cover is affected by the downward gravity of the gravity ball 113 and fits against the surface of the ash pile to form a conical shape with a diversion effect, so that the ash pile around the top of the drill hole is not easily blown by the wind, thereby reducing the dust from the ash pile.

[0024] like Figure 2 - Figure 3 As shown, considering that the hanging group 110 can be installed inside the cover body 101 through simple operations when needed, and can be quickly and conveniently removed from the cover body 101 through simple operation steps when the hanging group 110 is not needed, so as to be stored, maintained or replaced, a fixing rod 103 with rings at both ends is fixedly arranged at the center of the cover body 101, and the hanging group 110 includes a hook 111 and a gravity ball 113. The hook 111 is a quick bending hook with an anti-drop safety buckle, which is convenient to hang and not easy to fall off. A hanging ring is welded and fixed on the top of the gravity ball 113, and a connecting rod 103 is provided between the hanging ring of the gravity ball 113 and the hook 111. The rope 112 and the hook 111 are hung in the ring at one end of the fixed rod 103, and the gravity ball 113 falls vertically into the hole below the center of the bottom of the ash pile through the connecting rope 112, thereby closing the drill hole. The dust cover and the gravity ball 113 can be customized in batches according to the actual site and reused to save costs. At the same time, in order to facilitate the fixing of detailed information labels such as the drilling position, soil layer in the hole, cracks, cave conditions, aperture, depth, function, etc. on the surface of the cover body 101 for data review before subsequent operations, a slot 102 is fixed on the surface of the cover body 101, and the label is fixed in the slot 102 by plugging.

[0025] It should be further explained that the cover body 101 is made of PE (polyethylene) plastic, which is non-toxic, odorless, corrosion-resistant, and has good high and low temperature resistance, and can be exposed to open air for a long time; the fixed rod 103, hook 111, connecting rope 112, and gravity ball 113 are all coated to prevent corrosion and greatly increase the service life of the device.
