Description

Technical Field

[0001] The utility model belongs to the technical field of cableway equipment, and in particular relates to a grounding rod associated structure used for safe starting of a reciprocating cableway. Background Art

[0002] The grounding rod is a lightning protection and grounding component of the cableway equipment. It is used to clamp the grounding rod on the traction rope of the traction rope wheel to safely disperse the lightning energy and discharge it into the earth. When encountering thunderstorms, the cableway equipment stops running, and the grounding rod needs to be clamped on the traction rope to disperse the lightning energy. When the cableway is to be started, the current operation is to remove the grounding rod from the traction rope first, and then start the equipment. However, when the operator forgets to remove the grounding rod from the traction rope, the cableway can still start running. Then the traction rope will pull the grounding rod to move and roll the grounding rod into the running equipment, causing problems such as wire rope clamping and equipment damage. Therefore, it is necessary to propose improvements. Utility Model Content

[0003] The technical problem solved by the utility model is to provide a grounding rod associated structure for the safe starting of a reciprocating ropeway. The utility model aims to solve the problems of wire rope breakage and equipment damage caused by the grounding rod being drawn into the running equipment when the ropeway is started when the grounding rod is forgotten to be removed from the traction rope.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] The grounding rod associated structure for the safe start of a reciprocating ropeway has a traction rope wheel in the ropeway equipment, the traction rope wheel is wound with a traction steel rope for traction of the ropeway carriage, the traction steel rope is connected to the grounding rod by clamping and realizes lightning protection grounding in thunderstorms, a travel switch is arranged near the traction rope wheel, the travel switch is connected to the circuit for controlling the start and stop of the ropeway equipment, and the grounding rod contacts the travel switch after being separated from the traction steel rope to close the travel switch to ensure that the ropeway equipment can be started and stopped.

[0006] To further limit the above scheme, the travel switch is connected to the maintenance circuit in the cableway equipment control circuit through electric wires, the travel switch is connected in series with the relay k1113 and the maintenance stop switch S105 in the maintenance circuit, the travel switch controls the power supply and loss of the coil of the relay k1113, and the normally open contact of the relay k1113 controls the start and stop of the cableway equipment.

[0007] As a further limitation of the above solution, the travel switch is fixed on a wall or a bracket around the traction rope large wheel.

[0008] To further limit the above scheme, the travel switch is provided with a trigger rod for closing and opening the switch, the trigger rod of the travel switch is open in a free state and the cableway equipment cannot be started, and the grounding rod is provided with a hook, the hook of the grounding rod is hung on the trigger rod of the travel switch to make the trigger rod rotate downward and close the travel switch to ensure that the cableway equipment can be started.

[0009] As a further limitation of the above scheme, one end of the ground rod is provided with a C-shaped clamping head for clamping and connecting the traction steel rope, and a hook is fixedly provided on the back side of the C-shaped clamping head.

[0010] The advantages of this utility model compared with the prior art:

[0011] This solution aims at the problems existing in the use of the grounding rod of the ropeway equipment. By leading out an electric wire in the ropeway operation control circuit to connect a travel switch, when the grounding rod is clamped on the traction rope, the travel switch is in a freely open state, and the ropeway equipment cannot be started at this time. Only when the grounding rod is removed from the traction rope and then hung on the travel switch, the gravity of the grounding rod causes the contact point of the travel switch to rotate and conduct, can the ropeway equipment control circuit start and run. This structure limits the start of the ropeway equipment to the point where the grounding rod must be removed from the traction rope and the travel switch is triggered, thereby avoiding safety hazards such as the grounding rod being drawn into the operating equipment along with the traction rope due to the grounding rod not being removed from the traction rope, causing the wire rope to be clamped off and the equipment to be damaged.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0017] See also Figure 1-3 , describe the embodiments of the present utility model in detail.

[0018] Example: Ground rod associated structure for safe starting of reciprocating ropeway, see Figure 1 As shown, there is a traction rope wheel 1 in the cableway equipment, and a traction steel rope 2 for traction of the cableway carriage is wound on the traction rope wheel 1. The traction steel rope 2 is connected to a grounding rod 3 by clamping to achieve lightning protection grounding on rainy days. A travel switch 5 is arranged near the traction rope wheel 1, and the travel switch 5 is connected to the circuit for controlling the start and stop of the cableway equipment. After the grounding rod 3 is separated from the traction steel rope 2, it contacts the travel switch 5 to close the travel switch 5 to ensure that the cableway equipment can be started and stopped.

[0019] In this embodiment, a wire is led out from the ropeway operation control circuit to connect a travel switch. When the grounding rod is clamped on the traction steel rope, the travel switch is in a freely open state. At this time, the ropeway equipment cannot be started. Only when the grounding rod is removed from the traction steel rope and then hung on the travel switch, the gravity of the grounding rod makes the travel switch conductive, can the ropeway equipment control circuit be started and run. This structure limits the start of the ropeway equipment to the point where the grounding rod is removed from the traction steel rope and the travel switch is triggered, thereby avoiding safety hazards such as the grounding rod being drawn into the operating equipment and causing the wire rope to be clamped off and the equipment to be damaged due to the grounding rod not being removed from the traction steel rope.

[0020] In a specific embodiment: the travel switch 5 is connected to the maintenance circuit in the cableway equipment control circuit through an electric wire, see Figure 2 As shown, the travel switch 5 is connected in series with the relay k1113 and the maintenance safety stop switch S105 in the maintenance circuit. The travel switch 5 controls the power supply and loss supply of the coil of the relay k1113. The normally open contact of the relay k1113 controls the start and stop of the ropeway equipment.

[0021] In the above structure, a travel switch is installed on the line to control the power supply and loss of the coil of relay k1113, so that the normally open contact of k1113 can control the parking. The structure is simple and the operation is convenient.

[0022] In a specific implementation manner: the travel switch 5 is fixed on a wall 4 or a bracket around the traction rope wheel 1.

[0023] In a specific implementation: see Figure 3 As shown, the travel switch 5 is a purchased part. When used, it is Figure 3 The circuit shown is connected and fixed in a designated position. A trigger rod 5-1 for closing and opening the switch is provided on the travel switch 5. The trigger rod 5-1 of the travel switch 5 is open in a free state and the cableway equipment cannot be started. A hook 3-2 is provided on the grounding rod 3. The hook 3-2 of the grounding rod 3 is hung on the trigger rod 5-1 of the travel switch 5 to make the trigger rod 5-1 rotate downward and close the travel switch 5 to ensure that the cableway equipment can be started.

[0024] The grounding rod involved in the above structure is a purchased finished product and is originally used on the cableway equipment. It only needs to be provided with a hook for hanging.

[0025] In a specific embodiment: one end of the ground rod 3 is provided with a C-type clamping head 3-1 for clamping and connecting the traction steel rope 2, and a clamping plate is provided in the C-type clamping head 3-1, which is connected to the ground rod through a screw rod, and when the screw rod rotates, the clamping plate moves to clamp the steel rope. A hook 3-2 is fixedly provided on the back of the C-type clamping head 3-1, which is convenient for hanging on the travel switch.
