Description

Technical Field

[0001] The utility model relates to the field of conveying devices, in particular to a coal conveying reset mechanism. Background Technique

[0002] There are several important reasons for using conveyor belts in power plant coal conveying:

[0003] 1. High-efficiency continuous conveying:

[0004] The conveyor belt can achieve continuous and uninterrupted conveying of coal. Compared with other intermittent conveying methods, it greatly improves the coal conveying efficiency. For example, in a large thermal power plant, a large amount of coal needs to be consumed every day. If the batch transportation method is adopted, it is not only time-consuming and laborious, but also difficult to meet the power generation demand. The conveyor belt can continuously and stably convey coal from the coal storage yard to in front of the boiler.

[0005] 2. Large conveying capacity:

[0006] The design of the conveyor belt can carry a large amount of coal and can meet the large-scale coal consumption demand of power plants. Taking a medium-sized power plant as an example, it may need to convey hundreds of tons or even thousands of tons of coal per hour. The wide and strong load-bearing capacity of the conveyor belt can easily handle such a conveying volume.

[0007] 3. Reducing labor costs:

[0008] Using the conveyor belt can reduce the workload of manual handling and loading / unloading of coal and reduce labor costs. Imagine if coal had to be manually shoveled and transported to the designated location, it would consume a large amount of manpower and time.

[0009] When the coal conveying device is conveying, the conveying belt is prone to deviation. Since there is no reset mechanism on the conveying device, the conveying belt after deviation is likely to cause coal to fall, resulting in waste of pulverized coal. Content of the Utility Model

[0010] The purpose of the utility model is to provide a coal conveying reset mechanism to solve the defects mentioned in the above background technique.

[0011] To achieve the above purpose, a coal conveying reset mechanism is provided, including a conveying device. A conveyor belt is installed on the conveying device. At the same time, a reset mechanism body is installed at the bottom of the conveyor belt. The reset mechanism body includes two groups of installation tracks fixed by brackets. The two sides of the surface of the installation track are respectively covered with a first reset piece and a second reset piece. The composition structures of the first reset piece and the second reset piece are the same. The first reset piece includes an installation piece covering the surface of the installation track, and the surface of the installation piece is fixedly connected to a connection seat through a fixing bolt. At the same time, a reset frame is welded and fixed on the surface of the connection seat, and the reset frame is clamped outside the conveyor belt.

[0012] Preferably, a positioning block is fixedly welded to the bottom of the mounting piece, a positioning groove is formed inside the mounting track, and the dimensions of the positioning groove and the positioning block are adapted to each other.

[0013] Preferably, the positioning block is slidably arranged inside the positioning groove, the cross-sections of the positioning groove and the positioning block are both isosceles trapezoid-shaped, and the positioning block is slidably arranged inside the positioning groove.

[0014] Preferably, two sets of strip-shaped openings are formed on the surface of the positioning groove, the strip-shaped openings are U-shaped, a stud is inserted inside the strip-shaped openings, and the top of the stud is fixed to the bottom of the positioning block.

[0015] Preferably, the positioning block is slidably arranged inside the positioning groove and is fixedly connected through the stud and the nut, and the nut is screwed on the outer side of the stud.

[0016] Preferably, four sets of reset frames are evenly arranged on the surface of the mounting piece, the reset frames are "U"-shaped structures made of metal materials, the distance between adjacent two sets of reset frames is the same, and four sets of reset frames are arranged on both sides of the conveyor belt.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] Both sides of the conveyor belt are respectively inserted inside the four sets of reset frames. Through the arrangement of two rows of reset frames, the conveyor belt during movement can be limited and guided, preventing the conveyor belt from tilting and running off track during movement, realizing the automatic deviation correction and reset work for the conveyor belt that is about to run off track, and ensuring the stability of the conveyor belt during movement;

[0019] The positioning block is slidably arranged inside the positioning groove and is locked through the stud and the nut. In this way, the distance between the first reset piece and the second reset piece is adjusted. By adjusting the distance between the first reset piece and the second reset piece, the deviation correction installation for conveyor belts with different widths is realized.
