Description

Technical Field

[0001] This utility model relates to the field of mining blast shelter technology, and in particular to a movable blast shelter for mining. Background Technology

[0002] An open-pit mine is a production and operation unit that uses open-pit mining methods to extract mineral resources. The main production systems of an open-pit mine include development and transportation systems, drilling and blasting and loading systems, spoil disposal systems, waterproofing and drainage systems, as well as production workshops for crushing, mineral processing, machine repair, vehicle repair, power supply, water supply, explosives preparation, tailings dams, etc. Some mines also have land reclamation systems. When blasting is carried out in the mine, the blasting personnel can enter the blast shelter. The blast shelter is a safety facility widely used in open-pit mines to avoid injury from flying rocks generated during blasting. Its main function is to prevent flying rocks generated during blasting from injuring the workers.

[0003] During blasting operations, workers will blast different locations. To ensure that blasting personnel can safely and promptly escape from the danger zone, the position of the blast shelter needs to be constantly adjusted. However, during the blasting process, flying debris will not only impact the structure of the blast shelter but also the facilities at the bottom of the blast shelter, causing damage to the bottom facilities and rendering the blast shelter immobile, thus affecting its use. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a mobile blast shelter for mining. It protects the facilities at the bottom of the blast shelter during blasting in open-pit mines, preventing damage from flying debris and increasing the service life of the blast shelter. This solves the problem of flying debris impacting the facilities at the bottom of the blast shelter, causing damage and rendering the blast shelter immobile, thus affecting its use.

[0005] This utility model provides the following technical solution: a movable blast shelter for mining, comprising a blast shelter, observation windows at the left and right ends of the front side of the blast shelter, a protective door at the center of the front side of the blast shelter, a handle fixedly installed at the right end of the front side of the protective door, a driver's seat inside the blast shelter, rollers movably installed at the four corners of the bottom of the blast shelter, a motor box fixedly installed at the bottom of the blast shelter, a motor fixedly installed inside the motor box, a connecting rod fixedly installed on the output shaft of the motor, a drive gear fixedly connected to the end of the connecting rod away from the motor, symmetrical sliding grooves on the left and right sides of the front side of the blast shelter, sliders movably installed inside the sliding grooves, a baffle fixedly connected to the outward end of the slider, a connecting plate fixedly installed at the center of the side of the baffle near the blast shelter, and teeth evenly arranged on the left side of the connecting plate, with the drive gear meshing with the teeth.

[0006] Furthermore, a rotating rod is threadedly connected to the middle of the baffle, a connecting block is movably sleeved at the bottom of the rotating rod, a rectangular plate is fixedly installed at the bottom of the connecting block, and fixed cones are evenly fixedly installed at the bottom of the rectangular plate. The fixed cones are movably inserted into the bottom of the baffle, and a rotating handle is fixedly installed at the top of the rotating rod.

[0007] Furthermore, the height of the baffle is greater than the height of the roller, the length of the baffle is the same as the length of the cannon shed, and the baffle is made of alloy material. Making the height of the baffle greater than the height of the roller allows the baffle to more comprehensively block the roller.

[0008] Furthermore, the rectangular plate is movably installed inside the baffle, and the front and rear sidewalls of the rectangular plate are in contact with the inner front and rear sidewalls of the baffle.

[0009] Compared with the prior art, the advantages of this utility model are as follows:

[0010] 1. The operator sits in the driver's seat and moves the blast shelter to the selected location. Then, the motor moves the baffle to protect the facilities at the bottom of the blast shelter from damage caused by flying rocks during the blasting process, thus affecting the normal use of the blast shelter. At the same time, the throttle is used to insert the fixing cone at the bottom of the rectangular plate into the bottom surface of the baffle to increase the stability of the baffle, thereby preventing the impact of the blasting process from knocking down the blast shelter and causing harm to the personnel inside.

[0011] 2. By using alloy baffles, the protective effect of the baffles can be improved, providing better protection for the facilities at the bottom of the blasting shelter and increasing the service life of the baffles. Then, by having the front and rear side walls of the rectangular plate adhere to the front and rear side walls of the inner side walls of the baffle, it is possible to prevent the rectangular plate from deflecting too much during movement, thereby affecting the stability of the fixed cone inserted into the ground.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-4 This utility model provides a movable blast shelter for mining, including a blast shelter 1. Observation windows 2 are respectively provided at the left and right ends of the front side of the blast shelter 1. A protective door 3 is provided in the middle of the front side of the blast shelter 1. A handle 4 is fixedly installed on the right end of the front side of the protective door 3. A driver's seat 5 is provided inside the blast shelter 1. Rollers 6 are movably installed at the four corners of the bottom of the blast shelter 1. A motor box 7 is fixedly installed at the bottom of the blast shelter 1. A motor 8 is fixedly installed inside the motor box 7. A connecting rod 9 is fixedly installed on the output shaft of the motor 8. A drive gear 10 is fixedly connected to the end of the connecting rod 9 away from the motor 8. Slide grooves 11 are symmetrically provided on the left and right sides of the front side of the blast shelter 1. A slider 12 is movably installed inside the slide groove 11. A baffle 13 is fixedly connected to the outward-facing end of the slider 12. A connecting plate 14 is fixedly installed in the middle of the side of the baffle 13 closest to the blast shelter 1. On the left side of 4, there are evenly arranged locking teeth 15. The drive gear 10 meshes with the locking teeth 15. The operator sits in the driver's seat 5 and moves the blast shelter 1 to the selected position. Before the blast, the motor 8 is started, and the connecting rod 9 fixedly installed on the output shaft of the motor 8 drives the drive gear 10 to rotate. During the rotation of the drive gear 10, the connecting plate 14 is raised and lowered through the locking teeth 15, which in turn raises and lowers the baffle 13. At the same time, during the movement of the baffle 13, the slider 12 moves in the slide groove 11, so that the baffle 13 can be raised and lowered stably. Then, the bottom of the baffle 13 stops moving when it touches the bottom surface, so that the baffle 13 protects the bottom facilities of the blast shelter 1 and prevents flying stones from damaging the bottom facilities of the blast shelter 1 during the blast, thus affecting the normal use of the blast shelter 1.

[0019] In this embodiment, a rotating rod 16 is threadedly connected to the middle of the baffle 13, a connecting block 17 is movably sleeved at the bottom of the rotating rod 16, a rectangular plate 18 is fixedly installed at the bottom of the connecting block 17, and a fixing cone 19 is evenly fixedly installed at the bottom of the rectangular plate 18. The fixing cone 19 is movably inserted into the bottom of the baffle 13, and a rotating handle 20 is fixedly installed at the top of the rotating rod 16. When the bottom of the baffle 13 moves to abut against the bottom surface, the rotating handle 20 is rotated, causing the rotating rod 16 to rotate. Then, the rotating rod 16 moves the rectangular plate 18 through the connecting block 17 within the baffle 13. During the movement, the rectangular plate 18 carries the fixing cone 19 from the bottom of the baffle 13 into the bottom surface, thereby increasing the stability of the baffle 13 and preventing the impact generated during the blasting process from knocking down the blast shelter 1, thus avoiding harm to the personnel inside the blast shelter 1.

[0020] In this embodiment, the height of the baffle 13 is greater than the height of the roller 6, the length of the baffle 13 is the same as the length of the blast shelter 1, and the baffle 13 is made of alloy. By making the height of the baffle 13 greater than the height of the roller 6 and the length of the baffle 13 the same as the length of the blast shelter 1, the baffle 13 can provide more comprehensive protection for the bottom of the blast shelter 1, thereby increasing the safety of the bottom facilities of the blast shelter 1. At the same time, using an alloy baffle 13 can improve the service life of the baffle 13.

[0021] In this embodiment, the rectangular plate 18 is movably installed inside the baffle 13, and the front and rear sidewalls of the rectangular plate 18 are in contact with the front and rear sidewalls inside the baffle 13. By having the front and rear sidewalls of the rectangular plate 18 in contact with the front and rear sidewalls inside the baffle 13, the rotating rod 16 can move the rectangular plate 18 stably in the baffle 13 through the connecting block 17, thereby avoiding large deflection of the rectangular plate 18 during the movement, which would affect the stability of the fixed cone 19 inserted into the ground.

[0022] Working principle: The operator sits in the driver's seat 5 and moves the blast shelter 1 to the selected position. Before the blast, the motor 8 is started, causing the connecting rod 9, which is fixedly installed on the output shaft of the motor 8, to rotate the drive gear 10. During the rotation of the drive gear 10, the connecting plate 14 is raised and lowered through the locking teeth 15, which in turn causes the baffle 13 to rise and fall. At the same time, during the movement of the baffle 13, the slider 12 moves in the slide groove 11, thus allowing the baffle 13 to rise and fall stably. Then, the bottom of the baffle 13 moves... When the baffle 13 comes into contact with the bottom surface, it stops moving, thus protecting the bottom facilities of the blast shelter 1. When the bottom of the baffle 13 moves to contact the bottom surface, the handle 20 is turned, causing the handle 20 to rotate along the rotating rod 16. The rotating rod 16 then moves the rectangular plate 18 through the connecting block 17 within the baffle 13. During the movement, the rectangular plate 18 carries the fixed cone 19 from the bottom of the baffle 13 and inserts it into the bottom surface, thereby increasing the stability of the baffle 13 and preventing the impact generated during the blast from knocking down the blast shelter 1.
