Description

Technical Field

[0001] This invention relates to the field of mineral mining technology, specifically to a safety protection device for metal mines. Background Technology

[0002] Metallic minerals generally refer to minerals from which metallic elements can be extracted through smelting. Examples include ferrous metal minerals such as iron, manganese, chromium, vanadium, and titanium, which are used as raw materials in the iron and steel industry. Non-ferrous metal minerals include copper, tin, zinc, nickel, cobalt, tungsten, molybdenum, and mercury. Precious metals include platinum, rhodium, gold, and silver. Light metal minerals include aluminum and magnesium. Rare metal minerals include lithium, beryllium, and rare earth elements. Metallic minerals can be classified into five types according to their composition, properties, and uses: ferrous metal minerals, non-ferrous metal minerals, precious metal minerals, minerals containing dispersed elements, and semi-metallic minerals.

[0003] Mine roadways are a general term for various underground spaces carved into different rocks in different directions, at different angles, with different cross-sections and lengths, serving different ranges and for different purposes. Mine roadways are named and classified according to their spatial dimensions, dip direction, location, service range, and purpose.

[0004] Mine roadways require support structures. Support structures are measures taken to reinforce and protect the sidewalls and surrounding environment to ensure the safety of underground structure construction and the surrounding environment of the foundation pit.

[0005] Because each tunnel has a different size, traditional support frames are often arranged according to the different tunnel sizes, which greatly reduces the applicability of the frames.

[0006] Therefore, we propose a safety protection device for metal mines to solve the above problems. Summary of the Invention

[0007] The purpose of this invention is to provide a safety protection device for metal mines, which has an adjustment mechanism to drive two support platforms to move in opposite directions, so that the two support platforms are completely against the side wall of the roadway to provide support. The distance between the two support platforms can be adjusted according to the size of the roadway, which effectively improves the applicability of the device. Furthermore, the device as a whole is easy to disassemble and install, solving the problem that traditional support supports are often arranged according to the size of different roadways, which greatly reduces the applicability of the supports.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a metal mine safety protection device, comprising a support platform and two side plates symmetrically distributed on the outside of the support platform. Universal casters for movement are fixedly installed on the lower surfaces of both side plates. An adjustment mechanism for driving the two side plates to move in opposite directions is provided within the support platform. The adjustment mechanism includes two rotating shafts rotatably connected within the support platform and distributed opposite each other. First fully meshed gears are sleeved on the surfaces of both rotating shafts.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1

[0030] Please see Figures 1-5 The present invention provides a technical solution: a metal mine safety protection device, including a support platform 1 and two side plates 2 located outside the support platform 1 and symmetrically distributed. The lower surfaces of the two side plates 2 are fixedly installed with casters for movement. The support platform 1 is provided with an adjustment mechanism 3 for driving the two side plates 2 to move in opposite directions.

[0031] In use, by setting the adjustment mechanism 3, the two support platforms 1 can be driven to move in opposite directions so that the two support platforms 1 are completely against the side wall of the roadway, thus providing support. The distance between the two support platforms 1 can be adjusted according to the size of the roadway, which effectively improves the applicability of the device.

[0032] The adjustment mechanism 3 includes two rotating shafts 31 rotatably connected to the support platform 1 and distributed in opposite directions. The surfaces of the two rotating shafts 31 are fitted with first fully meshed gears 32. One end of one rotating shaft 31 extends to the outside of the support platform 1, and a rectangular shaft 33 is telescopically inserted into the extended end of the rotating shaft 31. A round rod 34 is fixedly connected to the free end of the rectangular shaft 33, and a handle 35 is fixedly connected to the free end of the round rod 34.

[0033] In use, the operator can manually rotate the round rod 34 through the handle 35. The round rod 34 can drive the rectangular shaft 33 fixed at one end to rotate. The rectangular shaft 33 can drive the rotating shaft 31 to rotate. Since the two rotating shafts 31 are fitted with the first fully meshed gear 32, the two rotating shafts 31 can rotate simultaneously and in opposite directions.

[0034] Each rotating shaft 31 has two threaded rods 361 with opposite thread directions fitted onto its surface, and each threaded rod 361 is fitted with an internal threaded sleeve 362 that is threadedly connected to it. The upper and lower sides of the internal threaded sleeve 362 are rotatably connected to a U-shaped frame 363. The surface of the U-shaped frame 363 is integrally fixedly connected to a swing rod 364. The free end of the swing rod 364 is rotatably connected to one of the support platforms 1. The two swing rods 364 on the same side form a V-shape, and the four swing rods 364 are diamond-shaped. The side wall of the support platform 1 is provided with a rectangular sliding groove 11 for the swing rods 364 to swing.

[0035] The side plate 2 has two vertically fixed horizontal plates 21 on the side near the support platform 1. The horizontal plates 21 are telescopically inserted into the side wall of the support platform 1.

[0036] In use, the rotating shaft 31 can drive the two threaded rods 361 sleeved on its surface to rotate. Since the threads on the two threaded rods 361 are opposite, the two internal threaded sleeves 362 located on the same rotating shaft 31 can move in opposite directions, so that the two internal threaded sleeves 362 can push the side plate 2 away from the bearing platform 1 through the U-shaped frame 363 and the swing rod 364, so that the side plate 2 abuts against the side wall of the tunnel.

[0037] Example 2

[0038] Please see Figure 6 This embodiment further illustrates Example 1, wherein three semi-circularly distributed arc-shaped plates 4 are provided above the support platform 1, and an extension mechanism 5 is used to drive the arc-shaped plates 4 to move away from the support platform 1.

[0039] In use, by setting the extension mechanism 5, the three arc plates 4 are driven to move away from the support platform 1, so that the arc plates 4 abut against the top surface of the inner wall of the tunnel for support, and the arc plates 4 can also be adapted to multiple tunnels of different sizes.

[0040] The extension mechanism 5 includes a semi-circular mounting base 51 fixed on the upper surface of the support platform 1. The surface of the semi-circular mounting base 51 has three evenly distributed rectangular grooves 52 and 53. The rectangular grooves 52 and 53 correspond one-to-one and are interconnected. A plate 54 is inserted into the rectangular groove 52. The arc plate 4 is fixedly connected to one side of the plate 54.

[0041] The insert plate 54 is fixedly connected to a long rod 55 located in the rectangular groove 53. The semi-circular mounting base 51 is rotatably connected to a semi-circular disk 56. The surface of the semi-circular disk 56 is provided with three evenly distributed inclined grooves 57. One end of the long rod 55 extends to the outside of the rectangular groove 53 and is slidably connected to the inclined groove 57.

[0042] The semi-circular mounting base 51 is rotatably connected to a second complete gear 581 that is coaxially fixed with the inclined groove 57, and the surface of the round rod 34 is sleeved with a third complete gear 582 that can mesh with the second complete gear 581.

[0043] In use, initially, the third complete gear 582 is in a position away from the second complete gear 581. The operator pushes the round rod 34 in the direction of arrow B using the handle 35. Arrow B is as shown. Figure 6 As shown, the round rod 34 can drive the rectangular shaft 33 fixed at one end and the third complete gear 582 sleeved on its surface to move in the direction of arrow B, so that the third complete gear 582 meshes with the second complete gear 581.

[0044] Then, by rotating the round rod 34 via the handle 35, the round rod 34 can drive the third complete gear 582 sleeved on its surface to rotate, the third complete gear 582 can drive the second complete gear 581 to rotate, and the second complete gear 581 can drive the semi-circular disk 56 fixed coaxially with it to rotate. The rotation direction of the semi-circular disk 56 is as follows: Figure 6 As shown by arrow C, the semi-circular disk 56 can drive the inclined groove 57 to rotate, the inner wall of the inclined groove 57 can push the long rod 55 to move away from the bearing platform 1, the long rod 55 can drive the insert plate 54 to move away from the bearing platform 1, and the insert plate 54 can drive the arc plate 4 fixed on one side to move away from the bearing platform 1, so that the arc plate 4 abuts against the top surface of the inner wall of the tunnel and plays a supporting role.

[0045] It also makes the device easy to disassemble and install.

[0046] Example 3

[0047] Please see Figure 7 This embodiment further illustrates Example 2, wherein the surface of the semi-circular mounting base 51 is provided with a locking mechanism 6 for locking the semi-circular disk 56.

[0048] In use, by setting the locking mechanism 6, the semi-circular disk 56 can be locked after rotating along arrow C, thereby locking the position of the arc plate 4 and making the arc plate 4 more supportive.

[0049] The locking mechanism 6 includes a column 61 fixedly connected to the side wall of the semi-circular disk 56. Several telescopic rods 62 are vertically fixed on the surface of the semi-circular mounting base 51. A locking block 63 is fixedly connected to one end of the telescopic rod 62. A spring 64 is fixedly connected between the locking block 63 and the semi-circular mounting base 51. One side of the surface of the locking block 63 is inclined.

[0050] In use, when the semicircular disk 56 rotates in the direction of arrow C, it can drive the column 61 fixed on its surface to rotate accordingly. The column 61 can push the inclined surface of the locking block 63, causing the locking block 63 to move closer to the semicircular mounting base 51, so that the column 61 can smoothly pass over the locking block 63.

[0051] Since the locking block 63 will squeeze the spring 64 when it moves closer to the semi-circular mounting base 51, the spring 64 can push the locking block 63 back to its original position after the column 61 passes the locking block 63.

[0052] Since the other side of the locking block 63 is a flat surface, the column 61 cannot move in the opposite direction of arrow C when there is no external force to push the locking block 63 toward the side closer to the semi-circular mounting base 51, thereby locking the position of the semi-circular disk 56 and effectively improving the support force of the arc plate 4.

[0053] Working principle: In use, the operator can manually rotate the round rod 34 through the handle 35. The round rod 34 can drive the rectangular shaft 33 fixed at one end to rotate. The rectangular shaft 33 can drive the rotating shaft 31 to rotate. Since the two rotating shafts 31 are fitted with the first fully meshed gear 32, the two rotating shafts 31 can rotate simultaneously and in opposite directions.

[0054] The rotating shaft 31 can drive the two threaded rods 361 sleeved on its surface to rotate. Since the threads on the two threaded rods 361 are opposite, the two internal threaded sleeves 362 located on the same rotating shaft 31 can move in opposite directions, so that the two internal threaded sleeves 362 can push the side plate 2 away from the bearing platform 1 through the U-shaped frame 363 and the swing rod 364, so that the side plate 2 abuts against the side wall of the tunnel.

[0055] Initially, the third complete gear 582 is in a position away from the second complete gear 581. The operator pushes the round rod 34 in the direction of arrow B using the handle 35. Arrow B is as follows: Figure 6 As shown, the round rod 34 can drive the rectangular shaft 33 fixed at one end and the third complete gear 582 sleeved on its surface to move in the direction of arrow B, so that the third complete gear 582 meshes with the second complete gear 581.

[0056] Then, by rotating the round rod 34 via the handle 35, the round rod 34 can drive the third complete gear 582 sleeved on its surface to rotate, the third complete gear 582 can drive the second complete gear 581 to rotate, and the second complete gear 581 can drive the semi-circular disk 56 fixed coaxially with it to rotate. The rotation direction of the semi-circular disk 56 is as follows: Figure 6 As shown by arrow C, the semi-circular disk 56 can drive the inclined groove 57 to rotate, the inner wall of the inclined groove 57 can push the long rod 55 to move away from the bearing platform 1, the long rod 55 can drive the insert plate 54 to move away from the bearing platform 1, and the insert plate 54 can drive the arc plate 4 fixed on one side to move away from the bearing platform 1, so that the arc plate 4 abuts against the top surface of the inner wall of the tunnel and plays a supporting role.

[0057] Furthermore, it allows for easy disassembly and assembly of the entire device;

[0058] When the semicircular disk 56 rotates in the direction of arrow C, it can drive the column 61 fixed on its surface to rotate accordingly. The column 61 can push the inclined surface of the locking block 63, causing the locking block 63 to move closer to the semicircular mounting base 51, so that the column 61 can smoothly pass over the locking block 63.

[0059] Since the locking block 63 will squeeze the spring 64 when it moves closer to the semi-circular mounting base 51, the spring 64 can push the locking block 63 back to its original position after the column 61 passes the locking block 63.

[0060] Since the other side of the locking block 63 is a flat surface, the column 61 cannot move in the opposite direction of arrow C when there is no external force to push the locking block 63 toward the side closer to the semi-circular mounting base 51, thereby locking the position of the semi-circular disk 56 and effectively improving the support force of the arc plate 4.

[0061] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
