Description

Technical Field

[0001] The utility model relates to the technical field of wire rope anti-vibration, and particularly relates to an anti-vibration device for the wire rope of an overhead manrider. Background Art

[0002] An overhead manrider is a commonly used personnel transportation device in the inclined roadway of a coal mine underground. Its seat is fixed on the wire rope through a connecting rod and a rope clamping device. When the wire rope moves, it carries people up and down. When the rope clamping device on the seat connecting rod passes through the rope supporting pulley, due to bumps, the wire rope shakes greatly. Seriously, the shaking of the wire rope will throw the rope clamping device out of the rope supporting pulley, resulting in the seat and the passengers falling to the ground. Content of the Utility Model

[0003] In view of the above technical problems, the utility model provides an anti-vibration device for the wire rope of an overhead manrider, which is used to solve the problem that when the rope clamping device of the seat connecting rod on the overhead manrider passes through the rope supporting pulley, there will be a large shake and it is easy to throw the rope clamping device out of the rope supporting pulley.

[0004] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0005] An anti-vibration device for the wire rope of an overhead manrider includes a connecting rod, a rope supporting pulley, a connecting piece and a first pin shaft. One end of the connecting rod is installed on the arch of the mine tunnel through the connecting piece, and the other end of the connecting rod is rotatably connected to the rope supporting pulley through the first pin shaft. A wire rope is arranged on the rope supporting pulley, and the wire rope is connected to the seat connecting rod through a rope clamping device. The device also includes a second pin shaft and a third pin shaft. A damping rod is vertically installed in the middle of the connecting rod. One end of the damping rod is rotatably connected to the connecting rod through the third pin shaft, and the other end of the damping rod is rotatably connected with a rope pressing wheel through the second pin shaft. The rope pressing wheel is installed above the wire rope, and the side surface of the rope pressing wheel is horizontally arranged opposite to the side surface of the rope supporting pulley. A tension spring is installed between the first pin shaft and the second pin shaft.

[0006] Compared with the prior art, the beneficial effect of the utility model is that the structure of the utility model is simple and the installation is convenient. When the rope clamping device of the overhead manrider seat shakes up and down due to bumps when passing through the rope supporting pulley, under the action of the tension spring, the rope pressing wheel fluctuates slightly up and down along with the wire rope, increasing the fluctuation resistance of the wire rope, quickly eliminating the shaking of the wire rope, preventing the wire rope from being thrown out of the rope supporting pulley groove, improving the stability of the wire rope, and ensuring the safety of the operators after taking the seat.

[0010] To make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below in combination with the specific implementation mode and with reference to the attached drawings. It should be understood that these descriptions are exemplary and not intended to limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0011] An anti-vibration device for the steel wire rope of an overhead personnel carrier includes a connecting rod 3, a rope supporting pulley 2, a first pin shaft 11, a second pin shaft 9 and a third pin shaft 4. One end of the connecting rod 3 is installed on the arch of the mine tunnel through a connecting piece 6, and the other end of the connecting rod 3 is rotatably connected to the rope supporting pulley 2 through the first pin shaft 11. A steel wire rope 1 is arranged on the rope supporting pulley 2. The steel wire rope 1 is connected to the seat connecting rod through a rope clamping device. A damping rod 7 is vertically installed in the middle of the connecting rod 3. The damping rod 7 is rotatably connected to the connecting rod 3 through the third pin shaft 4. The free end of the damping rod 7 is rotatably connected to a rope pressing pulley 8 through the second pin shaft 9. The rope pressing pulley 8 is installed above the steel wire rope 1. The side surface of the rope pressing pulley 8 is horizontally arranged opposite to the side surface of the rope supporting pulley 2. A tension spring 10 is installed between the first pin shaft 11 and the second pin shaft 9.

[0012] As Figure 1 shown, when the rope clamping device connected to the seat connecting rod passes through the rope supporting pulley 2 in the A direction, strong up and down shaking occurs. At this time, the rope pressing pulley 8 pressed on the upper part of the steel wire rope 1 fluctuates slightly up and down along with the steel wire rope 1 under the action of the tension spring 10, increasing the fluctuation damping of the steel wire rope 1, thereby eliminating the shaking of the steel wire rope 1, improving the stability of the steel wire rope 1, and ensuring the safety of the operators after they take the seat.

[0013] Embodiment 1

[0014] The damping rod 7 is in an L shape. The long arm end of the damping rod 7 is rotatably connected to the connecting rod 3 through the third pin shaft 4, and the short arm end of the damping rod 7 is rotatably connected to the rope pressing pulley 8 through the second pin shaft 9. Through the structural setting of the damping rod, it is ensured that the side surface of the rope pressing pulley 8 is horizontally arranged opposite to the side surface of the rope supporting pulley 2.

[0015] Embodiment 2

[0016] The second pin shaft 9 is relatively long, and the installation position of the rope pressing pulley 8 is adjusted on the second pin shaft 9 according to the position of the rope supporting pulley, so as to ensure that the side surface of the rope pressing pulley 8 is horizontally arranged opposite to the side surface of the rope supporting pulley 2.

[0017] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
