Description
Technical Field
The utility model relates to a coal mine machinery equips technical field, concretely relates to friction formula tail guard shield.
Background
In the comprehensive mechanical tunneling process of a coal mine, a second conveyor matched with a tunneling machine is usually adopted to transport coal. In the operation process of the belt conveyor, in order to ensure the safety of constructors, a belt conveyor tail protection device is arranged at the rotating part of the belt conveyor tail.
The rubber belt conveyor tail protective cover is too high to be manufactured due to the limitation of the roadway height and the conveying inclination angle of the second conveyor. If the tail protective cover of the belt conveyor is too high, the conveying inclination angle of the second conveyor is too large, and coal cannot be conveyed out along with the rotation of the second conveyor. Based on the reason of this kind of rubber belt conveyor tail protection casing height, in the work progress, because operating personnel misoperation, perhaps receive the influence of tunnel bottom plate roughness, the phenomenon of second conveyer to metal type rubber belt conveyor tail protection casing extrusion deformation often takes place, influences the normal operating of rubber belt conveyor to cause the unable normal use of metal type rubber belt conveyor tail protection casing.
Disclosure of Invention
In order to solve the problem, the utility model provides a friction formula tail guard shield.
In order to achieve the purpose, the utility model adopts the following technical proposal:
a friction type machine tail shield is used for a belt conveyor, wherein the belt conveyor comprises a belt of the belt conveyor, a coal cleaning port, a belt conveyor tail frame and a machine tail roller; the friction type machine tail protective cover comprises a top protective adhesive tape and a side protective adhesive tape which are made of rubber and connected into a whole, the top protective adhesive tape is fixedly connected with a machine tail frame of an adhesive tape machine through a U-shaped fixing clamp, the side protective adhesive tape is connected with the machine tail frame of the adhesive tape machine through a fixing bolt, one side of the side protective adhesive tape, which is close to a coal cleaning port, is aligned with the coal cleaning port, and the top protective adhesive tape and the adhesive tape of the adhesive tape machine are in a slight friction state at the position of a machine tail roller.
Furthermore, a is more than or equal to 20cm and less than or equal to 30 cm; the length of one side of the top protecting adhesive tape, which is close to the coal cleaning port and exceeds the coal cleaning port is a.
Further, 2cm is less than or equal to (b-c-d) is less than or equal to 4 cm; the width of the side protective adhesive tape is b, the diameter of the tail roller is c, and the thickness of the adhesive tape machine is d.
Further, the top protection adhesive tape and the side protection adhesive tape can be waste adhesive tapes for coal mines.
Has the advantages that: the rubber belt of the rubber belt conveyor cannot be damaged due to deformation, the normal use of the rubber belt conveyor cannot be influenced due to deformation, and the loss caused by deformation of the tail protective cover is reduced; the top protective adhesive tape and the side protective adhesive tape can use waste adhesive tapes for coal mines, and are made of local materials and waste materials are utilized.

Detailed Description
The present invention will be described in further detail with reference to the following embodiments and drawings.
Fig. 1 to 3 show a friction type tail shield for a belt conveyor, which includes a guide rail sliding shoe 1, a belt conveyor belt 2, a coal cleaning port 4, a belt conveyor tail frame 9, a tail drum 6 and a coal receiving plate 10; the friction type machine tail protective cover comprises a top protective adhesive tape 7 and a side protective adhesive tape 3 which are connected into a whole, the top protective adhesive tape 7 and the side protective adhesive tape 3 can use waste adhesive tapes for coal mines, the top protective adhesive tape 7 is fixedly connected with a tape machine tail frame 9 through a U-shaped fixing clamp 8, the side protective adhesive tape 3 is connected with the tape machine tail frame 9 through a fixing bolt 5, the length of the side protective adhesive tape 3 is suitable for not shielding a coal cleaning port 4, so that the coal cleaning operation can be conveniently and timely carried out, namely, one side, close to the coal cleaning port 4, of the side protective adhesive tape 3 is aligned with the coal cleaning port 4; if the length of the top protective adhesive tape 7, which is close to the coal cleaning port 4 and exceeds the coal cleaning port 4, is a, a is more than or equal to 20cm and less than or equal to 30cm, and the top protective adhesive tape 7 and the adhesive tape 2 of the adhesive tape machine are in a slight friction state at the position of the tail drum 6.
The width of the side protecting tape 3 is preferably slightly larger than the sum of the tail roller 6 and the tape 2 of the tape machine. The top protective tape 7 and the adhesive tape 2 of the adhesive tape machine are in a slight friction state at the position of the tail roller 6.
