Description

Technical Field

[0001] The utility model relates to the technical field of shell processing, in particular to an explosion-proof shell structure for mining equipment. Background Art

[0002] An explosion-proof housing is a shell or outer packaging used for explosion-proof (explosion-proof). It is usually used to wrap equipment, instruments or electrical equipment containing flammable and explosive substances to prevent these substances from catching fire or exploding, and to protect the safety of personnel and equipment. An explosion-proof housing is an essential and important safety device for mining equipment. In coal mines and other mining environments, there are flammable and explosive gases and dust, so mining equipment is prone to fire or explosion hazards. In order to ensure the safety of miners and equipment, measures must be taken to prevent accidents.

[0003] After searching, the Chinese patent authorization number CN212628817U discloses an explosion-proof shell, including an outer shell, an upper cover, a lower cover and fasteners. The outer shell is open at the top and bottom, and a mounting cavity is arranged inside the shell. A fixing platform for mounting electrical components is arranged inside the mounting cavity. The fixing platform is made of elastic metal and is provided with a mounting hole with an internal thread. A mounting bracket is provided on the outer facade of the outer shell, and the mounting bracket is provided with a U-shaped mounting notch. An explosion-proof shell in the above patent has the following deficiencies: 1. The device lacks a buffer structure. When the impact force generated by the explosion is too large, it directly faces the shell. Its single shell is easily damaged by itself, and its explosion-proof ability is limited; 2. When the device explodes, the fire source is easy to spread to the inside of the shell, thereby causing damage to the equipment, thereby missing the best time for emergency repairs, and lacking a structure for automatically isolating the fire source. Utility Model Content

[0004] The utility model aims to solve the problems in the prior art of lacking a buffer structure for coping with the impact force of a strong explosion, limited explosion-proof capability and lacking a structure for automatically isolating a fire source, and proposes an explosion-proof housing structure for mining equipment.

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

[0006] An explosion-proof housing structure for mining equipment comprises a front wall explosion-proof housing, wherein the outer wall of the front wall explosion-proof housing is fixedly connected with symmetrically distributed thick sliding rods, wherein the thick sliding rods are slidably connected through first sliding holes opened on the inner wall of a ventilation plate, and the first sliding holes are symmetrically distributed, wherein the inner wall of the ventilation plate is fixedly connected with symmetrically distributed evenly inclined plates, and further comprises:

[0007] A side buffer assembly, the side buffer assembly includes a thin sliding rod slidably connected to the inner wall of the main wall explosion-proof shell, and the thin sliding rods are symmetrically distributed, the outer wall of the thin sliding rod is sleeved with a first strong spring, and the first strong spring is fixedly connected to the inner wall of the main wall explosion-proof shell, one end of the thin sliding rod away from the inner wall of the main wall explosion-proof shell is fixedly connected to an arc-shaped slide plate, and the arc-shaped slide plate is slidably connected to the inner wall of the main wall explosion-proof shell, the arc-shaped slide plate is fixedly connected to the first strong spring, and one end of the arc-shaped slide plate away from the thin sliding rod is fixedly connected to the side wall explosion-proof shell;

[0008] A second sliding hole is provided on the inner wall of the ventilation plate;

[0009] The self-heating sealing component is arranged on the inner wall of the second sliding hole.

[0010] As a preferred technical solution of the present application, the self-heating sealing assembly includes a memory metal arranged on the inner wall of the second sliding hole, and the memory metal is fixedly connected to the main wall explosion-proof shell, and the end of the memory metal away from the main wall explosion-proof shell is fixedly connected to an isolation plate, and the outer wall of the isolation plate is slidably connected to a ventilation box body, and the inner wall of the ventilation box body is provided with symmetrically distributed ventilation holes.

[0011] As a preferred technical solution of the present application, an inner mounting box is fixedly connected to the outer wall of the ventilation box body, and the inner mounting box is fixedly connected to the ventilation plate.

[0012] As a preferred technical solution of the present application, the outer walls of the front wall explosion-proof shell and the side wall explosion-proof shell are fixedly connected with evenly distributed conical blocks.

[0013] As a preferred technical solution of the present application, a second strong spring is provided on the outer wall of the thick sliding rod, and the second strong spring is fixedly connected to the main wall explosion-proof shell, and one end of the second strong spring away from the main wall explosion-proof shell is fixedly connected to the ventilation plate.

[0014] Compared with the prior art, the utility model provides an explosion-proof housing structure for mining equipment, which has the following beneficial effects:

[0015] 1. The explosion-proof shell structure for mining equipment wraps the inner installation box by setting the front wall explosion-proof shell and the side wall explosion-proof shell, so as to cope with the impact force on the side and the front. At the same time, the special structure of the conical block and the arc-shaped slide plate can decompose part of the impact force and play a certain buffering role. If the impact force is too large, the side wall explosion-proof shell and the front wall explosion-proof shell can be adaptively slid a certain distance through the first strong spring and the thin slide bar and the second strong spring and the thick slide bar, so as to offset most of the impact force, avoid the excessive impact force directly acting on the inner installation box, improve the explosion-proof protection capability, and solve the problem of the limited explosion-proof capability of the prior art due to the lack of a buffer structure to cope with the impact force of a strong explosion;

[0016] 2. The explosion-proof shell structure of the mining equipment can automatically expand when heated through the memory metal. That is, when the fire source spreads and burns to the explosion-proof shell, the memory metal is heated and extended to drive the isolation plate to slide in the ventilation box body and then block the ventilation holes, thereby preventing the fire from extending through the ventilation holes to the inside of the inner installation box and causing damage to the internally installed equipment, providing valuable repair time, and solving the problem in the prior art of lacking a structure that automatically isolates the fire source to provide the best repair time.

The inner installation box 7 is made of heat-insulating and fire-proof materials and can be filled in a filling manner to save costs. It also includes:

[0027] A side buffer assembly, the side buffer assembly includes a thin sliding rod 5 slidably connected to the inner wall of the main wall explosion-proof shell 1, and the thin sliding rod 5 is symmetrically distributed, the outer wall of the thin sliding rod 5 is sleeved with a first strong spring 6, and the first strong spring 6 is fixedly connected to the inner wall of the main wall explosion-proof shell 1, the end of the thin sliding rod 5 away from the inner wall of the main wall explosion-proof shell 1 is fixedly connected to an arc-shaped slide plate 2, and the arc-shaped slide plate 2 is slidably connected to the inner wall of the main wall explosion-proof shell 1, the arc-shaped slide plate 2 is fixedly connected to the first strong spring 6, and the end of the arc-shaped slide plate 2 away from the thin sliding rod 5 is fixedly connected to the side wall explosion-proof shell 3. When the impact force is too large, the side wall explosion-proof shell 3 will react the impact force through the strong elastic action of the first strong spring 6, and the thin sliding rod 5 and the arc-shaped slide plate 2 slide a certain distance to offset the strong impact force, thereby preventing the impact force from directly impacting and causing deformation;

[0028] The second sliding hole 17 is formed on the inner wall of the ventilation plate 12;

[0029] The self-heating sealing component is arranged on the inner wall of the second sliding hole 17 .
