BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Attached Figure 1 This is a schematic diagram of a high-level pull rope across the conveyor;

[0013] Attached Figure 2 It is a schematic diagram of the connection between the high-position pull rope and the low-position pull rope. DETAILED DESCRIPTION

[0014] The utility model is further described below in conjunction with the accompanying drawings.

[0015] As attached Figures 1 to 2 The high-position pull rope device for self-rescue of a conveyor comprises a conveyor 1 and a high-position pull rope 2. A set of pull rope switches 3 are respectively arranged on both sides of the conveyor 1. When the pull rope switches 3 are subjected to tension, a stop signal is issued to control the stop of the conveyor 1. A low-position pull rope 4 is connected to the pull rope switch 3, and the low-position pull rope 4 is located on the side of the conveyor 1.

[0016] The high-position pull rope 2 spans over the conveyor 1, and there is a certain distance between the high-position pull rope 2 and the surface of the conveyor 1. When the conveyor 1 transports materials, the materials will not touch the high-position pull rope 2. Guide members are respectively provided on both sides of the conveyor 1, and the guide members can guide the high-position pull rope 2. The ends of the high-position pull rope 2 are guided by the guide members and bend downward. The two ends of the high-position pull rope 2 are bent downward and connected to the low-position pull ropes 4 on both sides of the conveyor 1. When the conveyor 1 is started by mistake, the trapped person on the conveyor 1 can pull the high-position pull rope 2, and the high-position pull rope 2 then pulls the pull rope switch 3 through the low-position pull rope 4, thereby controlling the conveyor 1 to stop and achieve self-rescue.

[0017] The guide member is a guide pipe 5, and the high-position pull rope 2 passes through the guide pipe 5. The high-position pull rope 2 is protected by the guide pipe 5, so that the high-position pull rope 2 is not easily reduced in strength under the interference of external factors. In specific applications, the high-position pull rope 2 is usually a steel wire rope, and the guide pipe 5 is a pipe made of carbon steel or stainless steel.

[0018] The conveyor 1 comprises a frame, and the guide pipe 5 is fixedly connected to the frame of the conveyor 1. In a specific application, the guide pipe is fixed to the frame of the conveyor 1 by welding.

[0019] The upper ends of the two guide pipes 5 are spaced relative to each other, so that the high-position pull rope 2 can be exposed from between the upper ends of the two guide pipes 5. The lower ends of the two guide pipes 5 face the low-position pull ropes 4 on both sides of the conveyor 1, and the ends of the high-position pull ropes 2 extend from the lower ends of the guide pipes 5 and are fixedly connected to the low-position pull ropes 4.

[0020] As attached Figure 1 As shown in the figure, the portion of the high-position pull rope 2 between the upper ends of the two guide pipes 5 is a tension section 6, and a plurality of short tubes 7 are strung on the tension section 6, which can protect the tension section 6 of the high-position pull rope 2. The outer tube wall of the short tube 7 is provided with rough textures, so that the trapped person on the conveyor 1 is not easy to slip off when holding the outer wall of the short tube 7.

[0021] As attached Figure 1 and 2 As shown in the figure, the guide pipe 5 includes a vertical straight pipe section 8, and the upper and lower ends of the straight pipe section 8 are respectively connected with elbows 9. The upper elbows 9 of the two straight pipe sections 8 are spaced opposite to each other, and the lower elbows 9 of the two straight pipe sections 8 are respectively facing the low-position pull ropes 4 on both sides of the conveyor 1, and the elbows 9 are connected with reducers 10 in an outwardly expanded shape, that is, the small-diameter end of the reducer 10 is connected to the elbow 9, and the reducer 10 can prevent the high-position pull rope 2 from getting stuck with the edge of the pipe.

[0022] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
