Description

Technical Field

[0001] The utility model belongs to the technical field related to phosphate rock mining, and particularly relates to an underground safety support device for phosphate rock mining. Background Technique

[0002] Phosphate rock refers to the general term for phosphate minerals that can be utilized economically. It is an important chemical mineral raw material. With it, phosphate fertilizers can be prepared, and it can also be used to manufacture yellow phosphorus, phosphoric acid, phosphides and other phosphates for use in industrial production such as medicine, food, matches, dyes, sugar making, ceramics, etc. Therefore, in the mining of phosphate rock, in order to ensure the stability of the position inside the phosphate rock mine, corresponding underground safety support devices need to be used.

[0003] However, when the existing underground safety support device is in use, the phosphate rock falling underground will accumulate on the upper end face of the device. Therefore, it does not have the function of diverting and sliding the falling phosphate rock, which will cause the falling phosphate rock to gradually accumulate, thereby increasing the load-bearing degree of the support device. At the same time, when diverting the falling phosphate rock, it does not have the function of collecting it, so it will accumulate inside the support device. For this reason, we provide an underground safety support device for phosphate rock mining to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide an underground safety support device for phosphate rock mining. Through the cooperation of the sliding groove and the inclined opening, the accumulated phosphate rock can be diverted, and at the same time, the storage box is located inside the L-shaped plate to recycle the diverted phosphate rock.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is an underground safety support device for phosphate rock mining, including a support plate in an inverted U shape; L-shaped plates are fixedly arranged at the left and right bottom positions inside the support plate, storage boxes are slidably arranged inside the L-shaped plates, sliding grooves are arranged on the periphery of the support plate, inclined openings communicating with the inside of the sliding grooves are arranged at both left and right ends of the support plate, and square openings are arranged at the upper parts of the opposite side walls of the two storage boxes.

[0007] The utility model is further arranged such that a plurality of through positioning holes are arranged at the bottom of the L-shaped plate, and the plurality of positioning holes are linearly arranged in the front and back direction and evenly distributed.

[0008] The utility model is further arranged such that positioning rods are fixedly arranged at the positions of the lower end faces of the storage boxes corresponding to the positioning holes, and the plurality of positioning rods are slidably inserted into the corresponding positioning holes.

[0009] The present utility model is further configured such that a placement opening is provided in the middle position of the upper end surface of the L-shaped plate, and a moving plate located inside the placement opening is fixed to the end surface of the storage box.

[0010] The present utility model is further configured such that the two inclined openings in the left-right direction are arranged in an inverted V shape, and the inclined openings are respectively provided above the square opening.

[0011] The present utility model is further configured such that T-shaped openings are provided in both the left and right parts of the front end surface of the support plate, and the T-shaped openings penetrate through the left and right parts of the support plate.

[0012] The present utility model is further configured such that I-shaped blocks are slidably inserted between two adjacent T-shaped openings in the front-rear direction, and pull rods are fixed to the opposite end faces of the two I-shaped blocks.

[0013] The present utility model has the following beneficial effects:

[0014] When the present utility model is in use, after the support plate is installed in the mine, the support plate protects the inner side wall of the mine. Thus, the fallen phosphate ore will fall to the position of the sliding groove and slide into the interior of the support plate from the inclined opening. At this time, the phosphate ore accumulated on the upper surface of the support plate is shunted, avoiding the accumulation of phosphate ore and ensuring that the support plate is not excessively squeezed.

[0015] When the present utility model is in use, the storage box is placed inside the L-shaped plate, and the opening position of the storage box is located below the inclined opening. Furthermore, the shunted phosphate ore will directly slide from the inclined opening into the storage box, thereby enabling the storage box to recover the sliding phosphate ore and avoiding blockage at the inner position of the support plate.

[0016] Of course, it is not necessary for any product implementing the present utility model to achieve all of the above advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the protection scope of the present utility model. Embodiment 1

[0027] Please refer to Figures 1 to 6 , the present utility model is an underground safety support device for phosphate ore mining. Through the cooperation of the sliding groove 101 and the inclined opening 102, the accumulated phosphate ore can be shunted, and at the same time, the storage box 3 is located inside the L-shaped plate 2 to recover the shunted phosphate ore.

[0028] Specifically, the support plate 1 in the shape of an inverted U; L-shaped plates 2 are fixedly arranged at the left and right bottom positions inside the support plate 1, storage boxes 3 are slidably arranged at the inner positions of the L-shaped plates 2, a sliding groove 101 is opened on the peripheral side of the support plate 1, inclined openings 102 communicating with the inside of the sliding groove 101 are opened at both ends of the left and right of the support plate 1, and square openings 301 are opened at the upper parts of the opposite side walls of the two storage boxes 3.

[0029] The operation process of this embodiment is as follows: After the support plate 1 is installed underground in the mine through the above structure, the support plate 1 protects the inner side wall underground in the mine. Thus, the fallen phosphate ore will fall to the position of the sliding groove 101 and slide from the inclined opening 102 to the inner position of the support plate 1. At this time, the phosphate ore accumulated on the upper surface of the support plate 1 is shunted to avoid the accumulation of phosphate ore and ensure that the support plate 1 is not overly squeezed. At the same time, the storage box 3 is placed inside the L-shaped plate 2, so that the opening position of the storage box 3 is below the inclined opening 102. Then, the shunted phosphate ore will directly slide from the inclined opening 102 into the storage box 3, thereby enabling the storage box 3 to recycle the sliding phosphate ore and avoiding blockage at the inner position of the support plate 1.

[0030] Furthermore, a placement opening 201 is provided in the middle of the upper end surface of the L-shaped plate 2. A moving plate 302 fixed to the end surface of the storage box 3 is located inside the placement opening 201. The two inclined openings 102 in the left-right direction are arranged in an inverted V shape, and the inclined openings 102 are respectively located above the square opening 301. After the storage box 3 is inside the L-shaped plate 2, the moving plate 302 can be set inside the placement opening 201. Then, when it is necessary to take out the storage box 3 from inside the L-shaped plate 2, the moving plate 302 can be directly taken out from inside the placement opening 201, thereby controlling the storage box 3 to tilt inside the L-shaped plate 2, facilitating the movement of the storage box 3. Embodiment 2

[0031] Please refer to Figure Figure 3 and Figure 5 , on the basis of Embodiment 1, by positioning the positioning rod 304 inside the positioning hole 104, the position of the storage box 3 can be positioned.

[0032] Specifically, a plurality of positioning holes 104 are provided in the bottom of the L-shaped plate 2 in a penetrating manner, and the plurality of positioning holes 104 are linearly and evenly distributed in the front-rear direction. Positioning rods 304 are fixed to the lower end surface of the storage box 3 corresponding to the positions of the positioning holes 104, and the plurality of positioning rods 304 are slidably inserted into the corresponding positioning holes 104.

[0033] The operation process of this embodiment is as follows: When the storage box 3 is placed inside the L-shaped plate 2, the positioning rods 304 at the bottom of the storage box 3 can be inserted into the positioning holes 104. Thus, the positioning holes 104 limit the positioning rods 304, further limiting the storage box 3 and ensuring the stability of the storage box 3 inside the L-shaped plate 2. Embodiment 3

[0034] Please refer to Figure 2 , Figure 3 and Figure 6, on the basis of Embodiment 1, the I-shaped block 4 is inserted into the inner positions of two adjacent T-shaped openings 103 to assemble the two support plates 1 accordingly.

[0035] Specifically, T-shaped openings 103 are formed in the left and right parts of the front end face of the support plate 1, and the T-shaped openings 103 penetrate through the left and right parts of the support plate 1. An I-shaped block 4 is slidably inserted between two adjacent T-shaped openings 103 in the front-to-back direction. Pull rods 401 are fixed to the opposite end faces of the two I-shaped blocks 4.

[0036] The operation process of this embodiment is as follows: Then, a plurality of support plates 1 are installed inside the mine, enabling two support plates 1 in the front-to-back direction to abut against each other. As a result, the T-shaped openings 103 on the front and back end faces of the support plate 1 will be adjacent. At this time, the I-shaped block 4 is inserted into the inner positions of the two adjacent T-shaped openings 103, thereby assembling the two support plates 1 that are adjacent front and back. Meanwhile, when it is necessary to remove the I-shaped block 4, the I-shaped block 4 can be directly pulled by the pull rod 401, and thus the I-shaped block 4 can be withdrawn from the inside of the T-shaped opening 103.
