Description

Technical Field

[0001] The present invention relates to the technical field of pull rope switches, in particular to a safety pull rope device and a belt conveyor. Background Art

[0002] Belt conveyors are widely used in the field of cargo transportation due to their high conveying capacity, long conveying distances, simple structure, easy maintenance, and convenient program control and automated operation. To prevent accidents during transportation, safety ropes are usually installed on both sides of the belt conveyor. In the event of an accident, the safety ropes trigger the belt conveyor's control circuit, causing the belt conveyor to stop urgently and prevent further escalation of the accident.

[0003] The existing safety pull ropes are usually set on both sides of the belt conveyor. If you want to trigger the pull rope switch, you need to stand on the ground on both sides of the belt conveyor. When the staff are not working on the ground on both sides of the belt conveyor, they need to walk to the safety pull rope positions on both sides of the belt conveyor before triggering the safety pull rope. This results in the inability to trigger the safety pull rope immediately when an accident occurs or the belt conveyor suddenly runs, which reduces the time efficiency for triggering the safety pull rope, easily causes harm to the personal safety of the staff, and reduces the safety of the belt conveyor.

[0004] Therefore, how to improve the safety of belt conveyors is a technical problem that those skilled in the art currently need to solve. Summary of the Invention

[0005] In view of this, an object of the present invention is to provide a safety rope pulling device to improve the safety of a belt conveyor.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] A safety rope pull device is used for a belt conveyor, wherein the belt conveyor includes two side beams arranged opposite to each other, namely a first side beam and a second side beam. The safety rope pull device includes at least one set of safety rope assemblies, and the safety rope assemblies include:

[0008] a first bracket provided on one side of the belt conveyor;

[0009] a first pull cord assembly having a first pull cord, wherein the first pull cord assembly is rotatably connected to the first bracket, and rotating the first pull cord assembly can trigger a switch of the first pull cord assembly;

[0010] a second bracket disposed on the other side of the belt conveyor, wherein the first bracket and the second bracket are disposed opposite to each other;

[0011] a second pull cord assembly having a second pull cord, the second pull cord assembly being rotatably connected to the second bracket, and rotating the second pull cord assembly can trigger a switch of the second pull cord assembly;

[0012] A first connecting rod is provided between the first pull rope group and the second pull rope group, and the first connecting rod is located above the belt conveyor.

[0013] Preferably, in the above safety pull rope device, the first pull rope group and the second pull rope group have the same structure, the first pull rope group includes a connecting shaft connected to the first connecting rod, and the connecting shaft is rotatably connected to the first bracket.

[0014] Preferably, in the above-mentioned safety rope pulling device, a first connecting hole is provided at one end of the connecting shaft connected to the first connecting rod, and the first connecting hole can cooperate with the first connecting rod.

[0015] Preferably, in the above safety rope pulling device, the first connecting hole and the first connecting rod are connected by bolts.

[0016] Preferably, in the above safety pull rope device, the first pull rope group further includes a second connecting rod connected to an end of the connecting shaft away from the first connecting rod, and an end of the second connecting rod away from the connecting shaft is connected to the first pull rope.

[0017] Preferably, in the above safety pull rope device, the first pull rope and the second connecting rod are connected by a rope clamp.

[0018] Preferably, in the above safety rope pulling device, the second connecting rod is an L-shaped connecting rod.

[0019] Preferably, in the above safety pull rope device, the first pull rope group and the first bracket are rotatably connected via a second connecting member.

[0020] Preferably, in the above safety rope pulling device, the second connecting member is a U-shaped bracket, and the two side walls of the U-shaped bracket are provided with second connecting holes.

[0021] Preferably, in the above safety rope pulling device, the first bracket is arranged on the first side beam, and the second bracket is arranged on the second side beam.

[0022] When using the safety pull rope device provided by the present invention, the first bracket and the second bracket are relatively arranged on both sides of the belt conveyor, the first pull rope group has a first pull rope, and the first pull rope group is rotatably connected to the first bracket. Therefore, a staff member standing on the side of the belt conveyor where the first pull rope group is set can pull the first pull rope to rotate the first pull rope group, thereby triggering the switch of the first pull rope group, causing the belt conveyor to stop urgently; the second pull rope group has a second pull rope, and the second pull rope group is rotatably connected to the second bracket. Therefore, a staff member standing on the side of the belt conveyor where the second pull rope group is set can pull the second pull rope to rotate the second pull rope group, thereby triggering the switch of the second pull rope group, causing the belt conveyor to stop urgently; since the first connecting rod is arranged between the first pull rope group and the second pull rope group, that is, the first connecting rod spans the width direction of the belt conveyor and is located above the belt conveyor, the staff member located above the belt conveyor can shake the first connecting rod, and the shaking first connecting rod drives the rotation of the first pull rope group and the second pull rope group, thereby triggering the switch of the first pull rope group and the second pull rope group, causing the belt conveyor to stop urgently. It can be seen that the safety pull rope device provided by the present invention can not only enable the first pull rope group and the second pull rope group to be immediately triggered by the staff standing on the ground on both sides of the belt conveyor when the belt conveyor suddenly starts running or an accident occurs, but also enable the staff located above the belt conveyor to immediately trigger the first pull rope group and the second pull rope group from above the belt conveyor without having to walk to the safety pull rope positions on both sides of the belt conveyor first, thereby improving the timeliness of triggering the safety pull rope device, thereby greatly reducing the damage that the belt conveyor may cause to the staff, and improving the safety of the belt conveyor.

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] like Figures 1 to 3 As shown, an embodiment of the present invention discloses a safety pull rope device for a belt conveyor 100. The belt conveyor 100 includes two oppositely arranged side beams, namely a first side beam 101 and a second side beam 102. The safety pull rope device includes at least one set of safety pull rope assemblies 200. The safety pull rope assembly 200 includes a first bracket 201, a first pull rope group 202, a second bracket 203, a second pull rope group 204 and a first connecting rod 205.

[0032] Among them, the first bracket 201 is arranged on one side of the belt conveyor 100; the first pull rope group 202 has a first pull rope 2023, and the first pull rope group 202 is rotatably connected to the first bracket 201, and rotating the first pull rope group 202 can trigger the switch of the first pull rope group 202; the second bracket 203 is arranged on the other side of the belt conveyor 100, and the first bracket 201 and the second bracket 203 are arranged opposite to each other; the second pull rope group 204 has a second pull rope, and the second pull rope group 204 is rotatably connected to the second bracket 203, and rotating the second pull rope group 204 can trigger the switch of the second pull rope group 204; the first connecting rod 205 is arranged between the first pull rope group 202 and the second pull rope group 204, and the first connecting rod 205 is located above the belt conveyor 100.

[0033] When the safety pull rope device provided by the present invention is used, the first bracket 201 and the second bracket 203 are relatively arranged on both sides of the belt conveyor 100, the first pull rope group 202 has a first pull rope 2023, and the first pull rope group 202 is rotatably connected to the first bracket 201, so that the staff standing on the side of the belt conveyor 100 where the first pull rope group 202 is set can pull the first pull rope 2023 to rotate the first pull rope group 202, thereby triggering the switch of the first pull rope group 202, causing the belt conveyor 100 to stop urgently; the second pull rope group 204 has a second pull rope, and the second pull rope group 204 is rotatably connected to the second bracket 203, so the staff standing on the side where the second pull rope group 204 is set The staff on one side pulls the second pull rope to rotate the second pull rope group 204, thereby triggering the switch of the second pull rope group 204, causing the belt conveyor 100 to stop urgently; since the first connecting rod 205 is arranged between the first pull rope group 202 and the second pull rope group 204, that is, the first connecting rod 205 spans the width direction of the belt conveyor 100 and is located above the belt conveyor 100, the staff located above the belt conveyor 100 can shake the first connecting rod 205, and the shaking first connecting rod 205 drives the first pull rope group 202 and the second pull rope group 204 to rotate, thereby triggering the switch of the first pull rope group 202 and the switch of the second pull rope group 204, causing the belt conveyor 100 to stop urgently. It can be seen that when the belt conveyor 100 suddenly starts running or an accident occurs, the safety pull rope device provided by the present invention can not only allow the first pull rope group 202 and the second pull rope group 204 to be immediately triggered by the staff standing on the ground on both sides of the belt conveyor 100, but also allows the staff located above the belt conveyor 100 to not have to walk to the safety pull rope positions on both sides of the belt conveyor 100 first. The first pull rope group 202 and the second pull rope group 204 can be immediately triggered above the belt conveyor 100, thereby improving the timeliness of triggering the safety pull rope device, thereby greatly reducing the possible damage to the staff caused by the belt conveyor 100 and improving the safety of the belt conveyor 100.

[0034] It should be noted that the first bracket 201 and the second bracket 203 can be a cylinder, a cube or a bracket structure welded by several support rods. As long as the structure can meet the mechanical performance requirements of the safety rope pull device, it falls within the scope of protection of the present invention; preferably, the embodiment of the present invention adopts a square column, which has a simple structure and is easy to process and manufacture.

[0035] In addition, the first bracket 201 can be directly set on the first side beam 101 of the belt conveyor 100, or it can be set on the side of the first side beam 101 away from the second side beam 102. As long as it can cooperate with the second bracket 203 to make the first connecting rod 205 located above the belt conveyor 100, it falls within the protection scope of the present invention; preferably, the embodiment of the present invention adopts the method of directly setting the first bracket 201 on the first side beam 101 to save installation space.

[0036] Similarly, the second bracket 203 can be directly set on the second side beam 102 of the belt conveyor 100, or it can be set on the side of the second side beam 102 away from the first side beam 101. As long as it can cooperate with the first bracket 201 so that the first connecting rod 205 is located above the belt conveyor 100, it falls within the protection scope of the present invention; preferably, the embodiment of the present invention adopts the method of directly setting the second bracket 203 on the second side beam 102 to save installation space.
