Description

Technical Field

[0001] The utility model relates to the technical field related to mine protection, in particular to a protective device for mine production safety. Background Art

[0002] The existing announcement number is: CN210856981U. A mining production safety protection device is installed with a spring and an inner rod. In the event of mountain rock rolling, the rock rolling falls and impacts the wire mesh. The connecting block of the wire mesh drives the inner rod to move outward, and the inner rod drives the push plate to squeeze the spring. The spring provides a reaction force, which effectively reduces the impact strength of the crushed stone, can reduce the hard contact and collision between the wire mesh and the rock rolling, reduce the frequency of replacement and maintenance, and reduce the cost of safety protection. It is suitable for wide promotion and use.

[0003] The above-mentioned existence is that when rolling stones fall and impact the wire mesh, the wire mesh will move as a whole in lateral position due to the movement of the inner rod. Although it can effectively reduce the impact strength of the gravel and reduce the probability of damage to the wire mesh, using a group of wire meshes to intercept may not be convenient for better interception of the gravel, and the protection has certain shortcomings. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a protective device for mine production safety.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A protective device for mine production safety includes support rods, two groups of support rods are processed with two groups of grooves, multiple groups of grooves are slidably connected with rods, multiple groups of tension springs are fixedly connected between the multiple groups of rods and the corresponding grooves, two groups of steel wire meshes are arranged between the two groups of support rods, and the two groups of steel wire meshes are respectively placed between the corresponding two groups of rods.

[0007] Preferably, the two groups of support rods are fixedly connected with a plate body, and the two groups of plate bodies are threadedly connected with multiple groups of columns.

[0008] Preferably, a plurality of groups of the rod bodies are respectively connected to one end of the corresponding steel mesh via bolts.

[0009] Preferably, one end and the other end of the two groups of support rods are fixedly connected with a through-hole block.

[0010] Preferably, the two groups of support rods are rotatably connected to each other via a connecting shaft and have two groups of rollers, and the multiple groups of rollers are respectively fitted with the corresponding outer walls of the wire mesh.

[0011] Preferably, the plurality of groups of columns are equidistantly distributed on the two groups of plates.

[0012] Preferably, the outer walls of the plurality of groups of columns are all fixedly connected with rubber sleeves.

[0013] The beneficial effects of the utility model are:

[0014] 1. Through the coordination between the support rod, trough body, rod body, tension spring and wire mesh, when the crushed stone contacts a set of wire mesh, the wire mesh will bend and deform, and at the same time, the two sets of rod bodies will drive the corresponding tension springs to stretch, so that the crushed stone can be unloaded to a certain extent. After the wire mesh is bent to a certain extent, it will contact another set of wire mesh, and with the help of the coordination of the other set of wire mesh and tension spring, the crushed stone can be further unloaded, which can reduce the probability of damage to the wire mesh and facilitate better interception of the crushed stone.

[0015] 2. Through the coordination between the set plates and columns, when two sets of wire meshes intercept the gravel, if the two sets of wire meshes are deformed to a certain extent and still cannot stably intercept the gravel, the wire meshes will contact with multiple sets of columns during the deformation process, thereby rigidly intercepting the gravel, which can reduce the probability of gravel breaking through the wire mesh and accidentally injuring people to a certain extent.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Example 1, reference Figures 1 to 5 A protective device for mine production safety includes a support rod 1, two groups of support rods 1 are processed with two groups of slots 2, multiple groups of slots 2 are slidably connected with rods 3, and rods 3 can slide in corresponding slots 2. Multiple groups of tension springs 4 are fixedly connected between multiple groups of rods 3 and corresponding slots 2. The tension springs 4 give the rods 3 a force to drive the wire mesh 5 to straighten and place. Two groups of wire meshes 5 are arranged between the two groups of support rods 1. The two groups of wire meshes 5 are placed between the corresponding two groups of rods 3. When one group of wire meshes 5 intercepts gravel, the wire meshes 5 The wire mesh 5 will bend and deform due to the contact with the gravel. At this time, the wire mesh 5 will pull the rod body 3 and stretch the tension spring 4. At this time, with the help of the bending of the wire mesh 5 and the elastic force of the tension spring 4, the gravel can be intercepted to a certain extent. If the wire mesh 5 is deformed to a certain extent and cannot intercept the gravel, the wire mesh 5 will contact with another group of wire meshes 5. With the help of the deformation of the two groups of wire meshes 5 and the cooperation of multiple groups of tension springs 4, a double interception operation can be performed, which can further unload the gravel and facilitate better interception of the gravel.

[0024] In this embodiment, the two groups of support rods 1 are fixedly connected with a plate body 6, and the two groups of plate bodies 6 are threadedly connected with multiple groups of columns 7. The columns 7 are used to intercept the crushed stones when the two groups of wire meshes 5 intercept the crushed stones and deform to a certain extent, so as to prevent the crushed stones from breaking through the wire meshes 5 and injuring people. The multiple groups of rod bodies 3 are respectively connected to one end of the corresponding wire mesh 5 by bolts 8. The one end and the other end of the two groups of support rods 1 are fixedly connected with a through-hole block 10, and the through-hole block 10 is used to connect the external connecting piece, thereby fixing the support rod 1 on the ground. The two groups of support rods 1 are rotatably connected with two groups of roller bodies 9 through a connecting shaft, and the multiple groups of roller bodies 9 are respectively fitted with the outer walls of the corresponding wire mesh 5. The roller bodies 9 are used to guide the wire mesh 5 to prevent the wire mesh 5 from contacting the corners of the support rod 1 when the wire mesh 5 intercepts the falling rocks and is deformed and bent, causing the wire mesh 5 to be worn. The multiple groups of columns 7 are equidistantly distributed at the two groups of plates 6. The outer walls of the multiple groups of columns 7 are fixed with rubber sleeves 11. The rubber sleeves 11 are used to increase the friction of holding, thereby facilitating the rotation of the columns 7 and separating the columns 7 from the two groups of plates 6 for replacement.

[0025] The working principle of this embodiment is as follows: when in use, an external connector is used at the through-hole block 10 to install two groups of support rods 1 on the ground. After installation, if the gravel rolls down, the gravel will contact a group of wire meshes 5. At this time, the wire meshes 5 will bend after being impacted, and pull the two groups of rod bodies 3 to move outward, and the tension springs 4 will be stretched. At this time, the tension springs 4 can be used to unload the debris to a certain extent. If one group of wire meshes 5 is bent to a certain extent and still cannot intercept the gravel, the wire meshes 5 will contact another group of wire meshes 5 to perform a second interception operation. If it still cannot be stably intercepted, the two groups of wire meshes 5 will contact multiple groups of columns 7 to rigidly intercept the gravel, thereby preventing the gravel from rushing out and injuring the staff, and a certain degree of protective operation can be performed.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
