Description

TECHNICAL FIELD

[0001] The utility model relates to a stone gateway coal conveying inclined roadway pull wire emergency stop mechanism and belongs to the technical field of coal mine conveying safety protection equipment. BACKGROUND

[0002] The mine belt conveyor emergency stop pull wire hook is a safety device for emergency stop equipment operation. When the mine belt conveyor has an emergency, the worker can pull the emergency stop pull wire hook to quickly cut off the operation of the conveyor to prevent the occurrence of the accident. Therefore, the emergency stop pull wire hook is an important safety guarantee tool on the mine belt conveyor, and must be used carefully.

[0003] The existing pull wire emergency stop hook uses many materials, is large in size, cannot be processed by using recycled materials, is high in cost, and is prone to blockage, rust, falling, core pulling, and breaking, leading to protection failure. UTILITY MODEL CONTENTS

[0004] The utility model solves the technical problems in the prior art.

[0005] The utility model takes the technical scheme that the stone gateway coal conveying inclined roadway pull wire emergency stop mechanism comprises a first mounting plate fixed horizontally on a channel steel of a frame of a conveyor belt, a second mounting plate and a third mounting plate arranged in a vertical direction are fixed below an end of the first mounting plate away from the channel steel, a pulley is rotationally connected between the second mounting plate and the third mounting plate, and a pull wire passes above the pulley.

[0006] Preferably, the pulley is installed between the second mounting plate and the third mounting plate through a second bolt.

[0007] Preferably, the spacing between the second mounting plate and the third mounting plate is 20-50 mm.

[0008] Preferably, the first mounting plate, the second mounting plate and the third mounting plate are all made of angle steel.

[0009] Preferably, a first fixing piece is horizontally arranged at the upper end of the channel steel, the middle part of the first fixing piece is in inverted V shape, the two ends of the first fixing piece are horizontal, one end of the first fixing piece is installed on the channel steel through a first bolt, and the other end of the first fixing piece is pressed on the other end of the first fixing piece and the channel steel through another first bolt.

[0010] Preferably, the first fixing piece is made of angle steel.

[0011] The utility model has the beneficial effects that:

[0012] 1. Compared with the existing technology, this utility model utilizes waste materials, reduces the resistance when pulling the cable during emergency stop, makes it less prone to jamming, prevents the cable from falling and dragging on the ground during emergency stop, makes it less likely to be pulled out of the core, and makes it less likely to be broken, thus reducing the protection failure rate; it also reduces maintenance efforts and personnel input, thereby saving production costs for the company.

[0013] 2. Compared with the prior art, this utility model is easier to process and its size is greatly reduced, thereby reducing space occupation, avoiding damage caused by errors in daily production, and reducing maintenance rate. Attached Figure Description

[0015] Fig. 2 This is a left view of part of the structure of this utility model.

[0016] The reference numerals in the accompanying drawings include: channel steel 1, first fastener 2, first bolt 3, first mounting plate 4, second mounting plate 5, third mounting plate 6, pulley 7, second bolt 8, and pull wire 9. Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Example

[0018] The emergency stop mechanism for the inclined shaft of the Shimen coal conveyor, such as... Figs. 1-2 As shown, a first fixing member 2 is parallel to the upper end of the channel steel 1. The middle part of the first fixing member 2 is inverted V-shaped, and both ends of the first fixing member 2 are horizontal. One end of the first fixing member 2 is installed on the channel steel 1 by a first bolt 3. The other end of the first fixing member 2 is fixed with a first mounting plate 4 arranged horizontally and perpendicular to the channel steel 1. A second mounting plate 5 and a third mounting plate 6 arranged vertically are welded to the lower left side of the first mounting plate 4, respectively. The distance between the second mounting plate 5 and the third mounting plate 6 is 30mm. A pulley 7 is rotatably connected between the second mounting plate 5 and the third mounting plate 6 by bolts, and a pull wire 9 passes through the pulley 7. The first fixing member 2 is used to increase the stability of the first mounting plate 4.

[0019] In this embodiment, the first mounting plate 4, the second mounting plate 5, the third mounting plate 6, and the first fixing member 2 are all made of recycled angle iron and angle steel, which saves production costs.

[0020] The above merely describes a specific implementation of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application, therefore, the protection scope of the present application should be subject to the protection scope of the claims.
