Description

Technical Field

[0001] The utility model relates to the field of scraper conveyors, and particularly to a deviation adjusting support for a roller of a scraper conveyor. Background Art

[0002] The chain belt type scraper conveyor is a material conveying and processing device, which is widely used in industries such as coal, building materials, chemical industry, and metallurgy. It can not only convey horizontally, but also convey obliquely or vertically. Its transportation capacity is not affected by the size and humidity of the cargo load, and it has the advantages of simple structure, good sealing performance, and flexible operation. However, due to the large working resistance, the following problems will occur when the chain belt type scraper conveyor is in use: (1) The rollers of the chain belt type scraper conveyor are prone to deviation during operation, and the scraper conveyor itself does not have a deviation adjusting function and cannot correct the deviation quickly, which affects the conveying efficiency; (2) After the chain belt deviates, it is necessary to frequently move the traditional roller support according to the deviation situation, which is time-consuming and laborious, and the deviation correction difficulty and intensity are large. Content of the Utility Model

[0003] The utility model provides a deviation adjusting support for a roller of a scraper conveyor, aiming at solving the problems that when the rollers of the chain belt type scraper conveyor deviate, it is impossible to quickly correct the deviation, which is time-consuming and laborious and affects the conveying efficiency.

[0004] To achieve its purpose, the utility model adopts the following technical solutions:

[0005] A deviation adjusting support for a roller of a scraper conveyor includes a roller, and both ends of the roller shaft of the roller respectively penetrate through a first support and a second support and are locked at their ends with lock nuts;

[0006] The first support is a fixed support;

[0007] The second support is an adjusting support, and adjusting bolts are symmetrically inserted on both sides of the second support, and the end parts of the adjusting bolts respectively abut against the side wall of the roller shaft in the second support; a pressing plate is detachably connected to the top of the second support.

[0008] Further, fastening bolts are symmetrically arranged on the top of the pressing plate, and the pressing plate is fixed on the top of the second support through the fastening bolts.

[0009] Further, the adjusting bolts are collinear with the roller shaft.

[0010] Further, sleeve bushes are sleeved on the roller shafts between the roller and the first support and between the roller and the second support.

[0011] Further, the bottoms of the first support and the second support are both in a groove shape.

[0012] Further, the bottoms of the first support and the second support are both fixedly connected to the base below the roller.

[0013] Further, the first support is of a channel steel structure.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] The idler roller deviation adjusting support for scraper conveyor provided by the present utility model is supported by the first support and the second support arranged on both sides of the idler roller, ensuring the stable operation of the idler roller of the scraper conveyor. The end parts of the roller shafts extending out of the first support and the second support are axially limited after being locked by lock nuts. Among them, the first support is a fixed support, and the second support is an adjusting support. When the idler roller runs off track, only need to turn the adjusting bolts on both sides of the second support to adjust its displacement amount, and then adjust the roller shaft in the second support to achieve the purpose of deviation correction. A pressing plate is detachably connected to the top of the second support. After the deviation correction is completed, the pressing plate is fixedly connected to the top of the second support for longitudinal limitation of the roller shaft, so as to achieve the purpose of quickly correcting the deviation of the idler roller of the scraper conveyor. It has strong practicability, convenient operation, and saves time and effort. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present utility model will be further described below with reference to the accompanying drawings:

[0021] As Figures 1-3 shown, the present utility model is an idler roller deviation adjusting support for scraper conveyor, including an idler roller 1. The two ends of the roller shaft 10 of the idler roller 1 respectively penetrate through the first support 2 and the second support 3 and are locked by lock nuts 9 at the end parts of the roller shaft 10; Bushing 8 is sleeved on the roller shaft 10 between the idler roller 1 and the first support 2, and between the idler roller 1 and the second support 3; The bottoms of the first support 2 and the second support 3 are both in groove shape, and the bottoms of the first support 2 and the second support 3 are fixedly connected to the base 7 below the idler roller 1;

[0022] The first support 2 is a fixed support made of channel steel;

[0023] The second support 3 is an adjustable support. Adjusting bolts 4 are symmetrically inserted on both sides of the second support 3, and the end parts of the adjusting bolts 4 are respectively abutted against the side walls of the roller shafts 10 in the second support 3, and the adjusting bolts 4 are collinear with the roller shafts 10. A pressing plate 5 is detachably connected to the top of the second support 3. Specifically, fastening bolts 6 are symmetrically arranged on the top of the pressing plate 5, and the pressing plate 5 is fixed to the top of the second support 3 through the fastening bolts 6.

[0024] During the conveying process, when it is found that the idler 1 of the scraper conveyor is offset, first turn the fastening bolt 6 on the top of the pressing plate 5 to loosen the pressing plate 5, and then turn the adjusting bolts 4 on both sides of the second support 3. By changing the displacement of the adjusting bolts 4, the offset roller shaft 10 is adjusted, so as to achieve the purpose of correcting the deviation of the idler of the scraper conveyor. After the deviation correction is completed, tighten the fastening bolt 6 on the top of the pressing plate 5 to fixedly connect the pressing plate 5 to the top of the second support 3 for longitudinal limit of the roller shaft. At the same time, the lock nuts 9 at both ends of the roller shaft 10 perform axial limit, so as to achieve the purpose of quickly correcting and limiting the deviation of the idler of the scraper conveyor.
