Description
Technical Field
The utility model relates to a anticreep round pin device, concretely relates to improved generation mine car bolt anticreep round pin device.
Background
With the increasing importance and strictness of the national security management of metal and nonmetal mines, a series of safety measures are correspondingly proposed for each process link and equipment in production, and the regulations of the metal and nonmetal mine safety regulations are as follows: the vehicle attachment does not result from a trip. At present, most of the widely used mine car bolt anti-pin-release devices adopt a special bolt (a hole is drilled in the upper part of the bolt and a locking pin shaft is welded) and a locking ring matched anti-pin-release device, and although a certain precaution effect can be achieved, certain design defects exist. The device has long service life and is easy to break the locking pin shaft at the upper part of the bolt due to collision and extrusion, thereby losing the self-locking function and being incapable of completely and effectively preventing the bolt from jumping out of the collision head of the mine car to cause the disconnection of the mine car connecting device and the potential safety hazard of production. When mine application tipper upset mine car unloads ore, the mine car gets into and carries out 180 upsets in the tipper, because the groove of lock ring is the slant, the mine car bolt falls out and falls into the ore bin from the lock ring easily, at this moment need get into and supply the bolt in the tipper, causes artificial potential safety hazard to seriously influence production efficiency. Meanwhile, the locking ring of the mine car connecting device needs to be machined in a casting process, a mine car pin shaft needs to be turned and drilled, and machining cost is high.
Disclosure of Invention
The utility model aims to solve the technical problem that the prior art is not enough to overcome, an improved generation mine car bolt anticreep round pin device that can solve purpose-built bolt and check ring matched with anticreep round pin device is at the anticreep round pin problem of 180 when overturning is provided.
The utility model provides a technical scheme that its technical problem adopted, an improved generation mine car anticreep round pin device, bump head and mine car bolt including the mine car, the mine car bumps overhead two blocks of cardboards of being fixed with, is equipped with the cardboard groove on the cardboard, the mine car bolt is located between two blocks of cardboards, and the upper portion of mine car bolt is fixed with the round steel, the width in cardboard groove is a bit larger than the external diameter of mine car bolt upper portion round steel, allows the round steel on the mine car bolt to transversely rotate, the round steel stretches out length and exceeds the cardboard outside, cardboard groove tail end is equipped with cotter location round hole, cotter location round hole's aperture is greater than the groove width.
Furthermore, the clamping plate groove is straight and smooth, the gap between the width of the clamping plate groove and the outer diameter of the round steel is 1-2 mm, and the round steel can transversely slide in the groove without resistance.
Furthermore, a gap of 5-10 mm is formed between the two clamping plates and the mine car bolt, so that the mine car bolt can rotate flexibly.
Furthermore, the extending length of the round steel exceeds the outer side of the clamping plate by 5-10 mm.
Furthermore, the aperture clearance between the round steel and the pin positioning round hole is 12-15 mm.
The utility model discloses following positive effect has: the utility model provides a purpose-built bolt and check ring matched with anticreep round pin device at the 180 off-round pin problems of upset when, easy and simple to handle, easy maintenance, the preparation technology only needs the oxygen to cut the electric welding technique, and is simple relatively, and the low grade characteristics of cost of manufacture have still solved because of bolt hole wearing and tearing or the problem that the split of fitting pin axle caused the inefficacy.
Drawings
FIG. 1 is a schematic structural diagram of an embodiment of the present invention;
FIG. 2 is a top view of FIG. 1;
FIG. 3 is a schematic structural diagram of the card board of FIG. 1.
In the figure: 1. the mine car positioning device comprises a mine car collision head, 2 mine car bolts, 3 clamping plates, 3-1 clamping plate grooves, 3-2 bolt positioning round holes, 4 round steel and 5 bolt lifting rings.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
Referring to the attached drawings 1-3, the mining car collision head comprises a mining car collision head 1 and a mining car bolt 2, wherein two clamping plates 3 are fixed on the mining car collision head 1, clamping plate grooves 3-1 are formed in the clamping plates, the mining car bolt 2 is arranged between the two clamping plates 3, round steel 4 is fixed on the upper portion of the mining car bolt 2, the width of the groove 3-1 of each clamping plate 3 is slightly larger than the outer diameter of the round steel 4 on the mining car bolt 2, the round steel 4 on the mining car bolt 2 is allowed to rotate transversely, the extending length of the round steel 4 exceeds the outer side of the clamping plate 3, a bolt positioning round hole 3-2 is arranged at the tail end of the clamping plate groove 3-1, and the aperture of the bolt positioning round hole 3-2 is larger than the groove width.
The clamping plate groove 3-1 is straight and smooth, the gap between the width and the outer diameter of the round steel 4 is 2 mm, and the round steel 4 on the mine car bolt 2 moves transversely in the groove without resistance.
A10 mm gap is formed between the two clamping plates 3 and the mine car bolt 2 (which is arranged in the mine car bolt hole), so that the mine car bolt 2 can flexibly rotate.
The length of the round steel 4 extending out of the clamping plate 3 exceeds 10 mm.
After the mine car bolt 2 is inserted into the mine car bolt hole in the mine car collision head 1, round steel 4 on the mine car bolt 2 can enter the bolt positioning round hole 3-2 along the clamp plate groove 3-1 in a mode of rotating the mine car bolt 2, and the clearance between the round steel 4 and the bolt positioning round hole 3-2 is 15 mm, so that the round steel 4 cannot slide out along the clamp plate groove in the bolt positioning round hole 3-2, the movement distance of the mine car bolt 2 is limited, and the effect of preventing the mine car bolt 2 from jumping out is achieved.
The amount of the mine car bolt 2 moving up and down in the mine car bolt hole is limited by the bolt positioning round hole 3-2 on the clamping plate 3, so that the mine car bolt hole is prevented from jumping out of the mine car bolt hole, a certain amount of movement is realized all around, and even if the mine car bolt hole has certain abrasion, the mine car bolt hole cannot be influenced.
Because the clamp plate groove 3-1 is straight and the aperture of the mine car bolt hole at the tail part is larger than the width of the groove 3-1, the mine car bolt 2 can not slide out, when the mine car enters the tipper and turns over for 180 degrees, the mine car bolt 2 does not need to be worried about to fall out, the working strength of operators is reduced, the working benefit is improved, and the use and maintenance cost is reduced.
Various modifications and variations of the present invention may be made by those skilled in the art, and they are still within the scope of the present invention, provided they are within the scope of the claims and their equivalents.
What is not described in detail in the specification is prior art that is well known to those skilled in the art.
