Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary mechanisms for strengthening the crossbeam of mining vehicles, and specifically refers to a crossbeam mechanism for strengthening the crossbeam of mining vehicles. Background Art

[0002] As the supporting part of a mining vehicle body, the structural stability of the crossbeam mechanism of a mining vehicle directly affects the use safety and service life of the mining vehicle. The existing crossbeam of a mining vehicle includes a group of crossbeam channel steels with openings facing inwards, and corresponding crossbeam sealing plates are fixedly welded at the openings of the crossbeam channel steels. To improve the strength of the crossbeam of the mining vehicle, a number of corresponding crossbeam mechanisms are generally additionally provided between a group of crossbeam channel steels.

[0003] The traditional crossbeam mechanism for strengthening the crossbeam of a mining vehicle generally includes a crossbeam body that is fixedly connected transversely through the crossbeam sealing plate and the crossbeam channel steel, and the crossbeam body is generally arranged in a tubular shape. The crossbeam body directly penetrates the crossbeam channel steel and the crossbeam sealing plate, and then is fixedly connected through corresponding welds. Although this improves the connection effect between the crossbeam body and the crossbeam channel steel and the crossbeam sealing plate to a certain extent, it reduces the strength of the crossbeam channel steel; in addition, due to the formation of welding stress, cracks are likely to appear at the welding joint between the crossbeam body and the crossbeam channel steel, which is very troublesome. Therefore, some manufacturers began to try to weld fixed pipe fittings on the inner side wall of the crossbeam channel steel, and then extend the inner end of the fixed pipe fittings through to the inner side of the crossbeam sealing plate. In this way, the crossbeam body can be fixedly inserted through the fixed pipe fittings, and then the crossbeam body is welded to the fixed pipe fittings through a single weld. In this way, although the problem of cracking at the welding joint between the crossbeam body and the crossbeam channel steel is solved, the force on the crossbeam body is often first transmitted to the connection between the fixed pipe fittings and the crossbeam body, and only after the crossbeam body is deformed will it be transmitted to the fixed pipe fittings, resulting in untimely and uneven force dispersion. Therefore, the weld between the fixed pipe fittings and the crossbeam channel steel is still relatively easy to crack. Once the single weld cracks, the overall stability of the crossbeam mechanism of the mining vehicle will be greatly challenged, and even major accidents may occur.

[0004] Therefore, the research purpose of the utility model is to design a crossbeam mechanism for strengthening the crossbeam of a mining vehicle that can effectively and timely disperse the force evenly, thereby significantly reducing the probability of cracking of the weld between the crossbeam body and the fixed pipe fittings; and when the weld between the crossbeam body and the fixed pipe fittings cracks, it can still maintain the connection stability between the crossbeam body and the crossbeam channel steel to prevent major accidents. Summary of the Invention

[0011] A pulling and locking mechanism for pulling and locking the pulling and fixing parts outwards to the corresponding frame channel steels. There are gaps respectively between the inner end parts of the crossbeam body and the inner side walls of the corresponding frame channel steels. After the pulling and fixing parts are locked to the frame channel steels, the pulling and fixing parts are fixedly pressed against the inner side surfaces of the limiting annular parts.

[0012] The pulling and locking mechanism includes a pull rod integrally formed and connected to the outer end part of the pulling and fixing part. The pull rod penetrates and extends to the outside of the frame channel steel and is locked and installed with a corresponding locking nut by a threaded connection method.

[0020] 1) The present utility model is additionally provided with a pulling and limiting mechanism, which includes a group of pulling and fixing parts movably sleeved on both sides of the crossbeam body, and limiting annular parts fixedly welded to the outer ends of the crossbeam body respectively; during the manufacturing process, the pulling and fixing parts are movably sleeved on the inner side of the crossbeam body in advance, and then the welding operation is carried out on the limiting annular parts; after the welding of the limiting annular parts is completed, the pulling and fixing parts are moved outwards, and the pulling and fixing parts are pulled and locked outwards to the corresponding girder channel steel through the pulling and locking mechanism, so that the pulling and fixing parts are fixedly pressed against the inner side surface of the limiting annular parts. In this way, the force on the crossbeam body can be effectively, timely and evenly dispersed to the first weld, as well as the connection parts of the limiting annular part, the pulling and fixing part and the girder channel steel. Thus, the probability of cracking of the weld between the crossbeam body and the fixed pipe fitting is significantly reduced, and when the weld between the crossbeam body and the fixed pipe fitting cracks, the connection stability between the crossbeam body and the girder channel steel can still be maintained to prevent major accidents from occurring.

Specific Embodiment

[0028] For the convenience of those skilled in the art to understand, the structure of the present utility model will be further described in detail below in conjunction with the drawings in the embodiments:

[0029] Referring to Figures 1 - 3 , a crossbeam mechanism for strengthening the girder of a mining vehicle, the girder of the mining vehicle includes a group of girder channel steels 101 with openings facing inwards, and corresponding girder sealing plates 102 are fixedly welded at the openings of the girder channel steels 101. The crossbeam mechanism is fixedly connected between a group of the girder channel steels 101, and the crossbeam mechanism includes:

[0030] A group of fixed pipe fittings 2, the outer ends of the fixed pipe fittings 2 are respectively fixed to the inner side walls of the corresponding girder channel steels 101, and the inner ends of the fixed pipe fittings 2 respectively penetrate and are fixedly connected to the inner sides of the corresponding girder sealing plates 102;

[0031] The crossbeam body 3 is tubular, and the crossbeam body 3 is movably inserted between a group of the fixed pipe fittings 2, and the joints between the crossbeam body 3 and the fixed pipe fittings 2 are respectively fixedly connected by corresponding first welds;

[0032] The pulling and limiting mechanism 4 includes a group of pulling and fixing members 401 movably sleeved on both sides of the crossbeam body 3. The outer ends of the pulling and fixing members 401 are respectively provided with corresponding top pushing chamfers. The outer ends of the crossbeam body 3 are respectively fixedly welded with corresponding limiting annular members 402, and the inner end faces of the limiting annular members 402 are respectively arranged in a slope shape adapted to the top pushing chamfers;

[0033] The pulling and locking mechanism 5 is used to pull and lock the pulling and fixing members 401 outwards to the corresponding girder channel steels 101. There are respectively clearance settings between the inner ends of the crossbeam body 3 and the inner side walls of the corresponding girder channel steels 101. After the pulling and fixing members 401 are locked to the girder channel steels 101, the pulling and fixing members 401 are fixedly pressed against the inner side surfaces of the limiting annular members 402.

[0034] The utility model is additionally provided with a pulling and limiting mechanism 4, which includes a group of pulling and fixing parts 401 movably sleeved on both sides of the beam body 3, and limiting annular parts 402 fixedly welded to the outer ends of the beam body 3 respectively; during the manufacturing process, the pulling and fixing parts 401 are movably sleeved on the inner side of the beam body 3 in advance, and then the welding operation is carried out on the limiting annular parts 402; after the limiting annular parts 402 are welded, the pulling and fixing parts 401 are moved outwards, and the pulling and fixing parts 401 are pulled and locked outwards to the corresponding girder channel steel 101 through the pulling and locking mechanism 5, so that the pulling and fixing parts 101 are fixedly pressed against the inner side surface of the limiting annular parts 402. In this way, the force on the beam body 3 can be effectively, timely and evenly dispersed to the first weld, as well as the joints of the limiting annular part 401, the pulling and fixing part 402, and the girder channel steel 101. Thus, the probability of cracking of the weld between the beam body 3 and the fixed pipe fitting 2 is significantly reduced, and when the weld between the beam body 3 and the fixed pipe fitting 2 cracks, the connection stability between the beam body 3 and the girder channel steel 101 can still be maintained to prevent major accidents from occurring.

[0035] The pulling and locking mechanism 5 includes a pull rod 501 integrally formed and connected to the outer end of the pulling and fixing part 401. The pull rod 501 penetrates and extends to the outside of the girder channel steel 101 and is locked and installed with a corresponding locking nut 502 by means of threaded connection. A plurality of locking bolts 503 locked to the pulling and fixing part 401 by means of threaded connection are arranged in a circular array on the girder channel steel 101 around the locking nut 502.

[0036] The pull rod 501 is locked by the locking nut 502, so as to form an outward tension and fixation on the pulling and fixing part 401; then, the pulling and fixing part 401 is further fixed outward by the uniformly distributed locking bolts 503, which can overall ensure the stable installation of the pulling and fixing part 401, that is, of the beam body 3.

[0037] Vibration damping components 6 are respectively fixedly connected to the inner end surfaces of the pulling and fixing parts 401. The vibration damping components 6 are vibration damping pads made of polymer damping materials. Through the arrangement of the vibration damping components 6, the vibration amount of the two stress concentration areas is reduced, that is, the vibration amount at the first weld and the position where the pulling and limiting mechanism 4 is located is reduced, so as to effectively maintain the structural stability of the first weld and the pulling and limiting mechanism 4, and further reduce the probability of cracking of the first weld and ensure the connection stability between the beam body 3 and the girder channel steel 101.

[0038] The joints of the fixed pipe fitting 2 with the inner side wall of the girder channel steel 101 and the girder cover plate 102 are respectively fixedly connected by corresponding second welds.

[0039] Embodiment Two:

[0040] Reference Figure 4 , the difference between this example and the first embodiment is that: the damping component 6 includes a fixed container 601 fixedly welded to the inner end surface of the pulling and fixing member 401, and a plurality of damping particles 602 for damping are filled in the fixed container 601. The damping particles 602 for vibration are spherical particles made of polymer materials.

[0041] By the friction energy consumption between the damping particles 602 for vibration, the vibration amount transmitted to the damping component 6 can be effectively reduced, thereby reducing the vibration amount at the two stress concentration regions, that is, reducing the vibration amount at the first weld seam and the position where the pulling and limiting mechanism 4 is located, so as to ensure the practical effect of the present utility model.

[0042] It should be noted that the implementation principle and the technical effects generated by this embodiment are the same as those of the first embodiment. For the sake of brief description, for the parts not mentioned in this embodiment, reference may be made to the corresponding content in the first embodiment.

[0043] The above are only the preferred embodiments of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
