Abstract
Description
Technical Field
[0001] The utility model relates to the field of overwinding switches for mines, in particular to a ground-starting self-returning overwinding switch for mines. Background Art
[0002] The mine overwind switch is a fixed detection instrument used to detect the position status of electromechanical equipment or mechanical equipment in coal mines. In modern mine construction, rope winches and hoists are vigorously promoted as auxiliary transportation methods. The operation control and safety protection of auxiliary transportation directly affect the production efficiency and safety of mines.
[0003] As an auxiliary device of the transport control system, the overwind switch transmits the signal to the transport control system, thereby protecting the rope winch and hoist at the starting point and the end point. At present, the signal transmission of the overwind switch is all wired, which not only increases the cost of wire laying when laying wires over long distances, but also makes installation and debugging inconvenient, and the guide rod is easily damaged by collision, resulting in failure to reset.
[0004] It should be noted that the above contents belong to the technical knowledge of the inventor and do not necessarily constitute prior art. Utility Model Content
[0005] In view of the above defects, the utility model provides a mine-used ground-starting self-resetting overwinding switch to solve the signal transmission and resetting problems of the mine-used overwinding switch.
[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0007] A mine-use ground-starting self-returning overwinding switch comprises a base and a shell fixedly mounted on the base, wherein an overwinding switch mechanism is arranged in the shell;
[0008] The overwinding switch mechanism includes a detection switch, a rotating disk, a torsion spring, a guide rod, a support frame, a coding control board and a launching board. The detection switch is installed on the left side of the outer shell, the rotating disk is movably inserted in the detection switch, the torsion spring is sleeved in the rotating disk, the bottom of the guide rod is connected to the rotating disk, the support frame is installed on the right side of the outer shell, the coding control board is installed at the front end of the support frame, and the launching board is installed at the upper end of the support frame.
[0009] Furthermore, limit rods are respectively installed at both ends of the torsion spring, and limit blocks corresponding to the limit rods are installed in the detection switch.
[0010] Furthermore, a steering angle sensor is installed at the bottom of the guide rod.
[0011] Furthermore, a transmitting antenna is installed at the right end of the shell.
[0012] Furthermore, a group of fixing holes are respectively opened on both sides of the base.
[0013] The utility model provides a self-resetting overwinding switch for mine use, which has the following beneficial effects: the self-resetting overwinding switch for mine use is an intrinsically safe type for mine use, suitable for occasions containing coal dust and gas in coal mines, and is used in conjunction with a main unit of a mine transportation protection device. When the winch overwinds, the mine car applies force to the guide rod of the detection switch, and the guide rod deflects along the axis of the detection switch. When the deflection angle is greater than 40° (the allowable error is ±5°), the switch is actuated, the normally open contact is connected, the normally closed contact is disconnected, and the signal is uploaded from the transmitting antenna to the control console of the transportation control system. The control console controls the winch or hoist to stop immediately. The wireless mode is adopted to facilitate engineering installation and debugging. After the winch leaves, the guide rod is automatically reset by the torsion spring. BRIEF DESCRIPTION OF THE DRAWINGS
