Description

Connecting structure between sieve beam and sieve plate of flip-flow sieve

Technical Field

The utility model relates to a connection structure between relaxation sieve roof beam and sieve specifically is a connection structure between relaxation sieve roof beam and sieve.

Background

In the tension and relaxation sieve original structure, be connected through several parallel arrangement's a channel-section steel supporting beam between sieve roof beam and the sieve, as shown in fig. 1 and fig. 2, a channel-section steel supporting beam and sieve roof beam vertically and horizontally staggered, each a channel-section steel supporting beam all is perpendicular to sieve roof beam and is connected with all sieve roof beams, and is specific, a channel-section steel supporting beam bottom place plane is perpendicular with sieve roof beam top surface, and a channel-section steel supporting beam lateral wall passes through bolt and nut subassembly fastening connection with sieve roof beam top surface, and another lateral wall of a channel-section steel supporting beam passes through bolt and nut subassembly. After a period of use, the connection structure between the screen beam and the screen plate of the flip-flow screen has serious structural defects, because each channel steel supporting beam is connected with all the screen beams, along with the vibration of the flip-flow screen, the material quantity of the screen front part and the screen rear part is different, the channel steel supporting beam is easy to break, the connection bolt between the screen plate pressing strip and the channel steel supporting beam is broken, and the screen plate falls. If maintain one of them channel-section steel supporting beam just need demolish whole sieve to and all sieve roof beams of being connected with a channel-section steel supporting beam all need dismantle the connection, and the maintenance volume is huge, and it is hard to take time to maintain, seriously influences the normal production of coal preparation factory.

Disclosure of Invention

The utility model aims at solving the technical problem in the background art, a connection structure between relaxation sieve roof beam and sieve is provided.

The utility model provides a technical means that its technical problem adopted is: the utility model provides a connection structure between relaxation sieve roof beam and sieve, every sieve roof beam top surface all welds several T shaped steel of invering of parallel arrangement, and T shaped steel length direction is perpendicular with sieve roof beam length direction, and the T shaped steel that the position corresponds on two adjacent sieve roof beams passes through the support angle steel to be connected, and the vertical setting of a lateral wall of support angle steel links to each other through two sets at least bolt-nut assemblies with the vertical roof beam of T shaped steel. The utility model discloses replace a channel-section steel supporting beam in the primary structure with T shaped steel and support angle steel, support angle steel section phase connection has replaced a whole channel-section steel supporting beam, like this along with the vibration of relaxation sieve, the support angle steel of different positions can avoid the uneven cracked problem of support angle steel atress that leads to because of the sieve material inequality in the vibration process, in the on-the-spot in-service use process, be difficult to appear a supporting beam incident, and even if there is the support angle steel of individuality to need the maintenance, only need to dismantle the support angle steel of damage alone change can, need not dismantle whole sieve, the maintenance has greatly been alleviateed, the maintenance work load.

The utility model has the advantages that: simple and practical, convenient operation utilizes T shaped steel and support angle steel to replace a channel-section steel supporting beam originally, in the in-situ in-service use process, is difficult to appear a supporting beam fracture accident, even if there is the individual support angle steel that needs the maintenance, only need with the support angle steel of damage dismantle alone change can, need not dismantle whole sieve get off, greatly alleviateed maintenance, maintenance work load.

Detailed Description

Referring to fig. 1-5, the connection structure between the beams and the sieve plates of the flip-flow sieve of the present invention will be described in detail.

A connecting structure between a tension and relaxation sieve beam and a sieve plate is shown in figures 3, 4, 5 and 6, wherein a plurality of inverted T-shaped steels 5 which are arranged in parallel are welded on the top surface of each sieve beam 1, namely transverse beams 6 of the T-shaped steels 5 are welded on the top surfaces of the sieve beams 1, the length directions of the T-shaped steels 5 are perpendicular to the length directions of the sieve beams 1, the T-shaped steels 5 which correspond to each other in position on two adjacent sieve beams 1 are connected through supporting angle steel 7, and one side wall of each supporting angle steel 7 is vertically arranged and is connected with a longitudinal beam 8 of each T-shaped steel 5 through at least two sets of bolt and nut assemblies 4. The utility model discloses replace a channel-section steel supporting beam 3 in the primary structure with T shaped steel 5 and supporting angle steel 7, supporting angle steel 7 section connection has replaced a whole channel-section steel supporting beam 3, like this along with the vibration of relaxation sieve, the supporting angle steel 7 of different positions can avoid leading to the cracked problem of supporting angle steel 7 atress inequality because of the material inequality on the sieve 2 in the vibration process, in the on-the-spot in-service use process, be difficult to appear a supporting beam incident of rupture, and even if there is individual supporting angle steel 7 that needs the maintenance, only need to dismantle the supporting angle steel 7 of damage alone change can, need not dismantle whole sieve 2 and get off, the maintenance has greatly alleviateed, the maintenance work load.

Further, as a specific implementation of a connection structure between relaxation sieve roof beam and sieve, as shown in fig. 5, the vertical roof beam 8 of T shaped steel 5 is located support angle steel 7 is inboard. Therefore, the longitudinal beam 8 of the T-shaped steel 5 can support the horizontal side wall of the support angle steel 7, and the structure is more reasonable.

Further, as a specific embodiment of the connection structure between the tension and relaxation sieve beam and the sieve plate of the present invention, as shown in fig. 4 and fig. 6, the length of the T-shaped steel 5 is smaller than the width of the sieve beam 1. Except for the T-shaped steels 5 on the two screen beams 1 at the edge, the T-shaped steel 5 on each screen beam 1 in the middle is connected with two sections of supporting angle steel 7, which are respectively used for being connected with the T-shaped steels 5 of the two adjacent screen beams 1, and the length of the T-shaped steel 5 is less than the width of the screen beam 1, so that the stable connection can be met, and the adjacent screen beam 1 can be influenced if the length is too long.
