[0002] At present, the coiled cable limiting device for underground mining equipment such as figure 1 , figure 2 As shown, the limit switch 15 is opened by the threaded transmission of the lead screw 16 and the nut 14 arranged on the support plate 17. The lead screw 16 is often designed to be relatively long, so the installation takes up a large space, and the lead screw 16 is easy to break. Cause limit switch 15 to fail, currently there is only one limit switch for equipment, and the safety is low

The invention relates to a coil cable limit device for underground mobile equipment, which is particularly suitable for underground equipment and belongs to the technical field of a structure of mining machinery equipment. The coil cable limit device comprises a limiter arranged at one side of a support plate. The other side of the support plate is provided with a chain wheel which is coaxial with a worm in the limiter. A worm gear in drive connection with the worm is arranged in the limiter. A worm gear shaft of the worm gear is provided with a cam. A limit switch is arranged at the position which can be in contact with a flange part of the cam in the limiter. The tail end of the worm gear shaft is provided with a pressure spring, wherein the pressure spring is wound on the shaft wall of the worm gear shaft and one end of the pressure spring is connected with the cam. The other end of the pressure spring is connected with a gland fixedly arranged on the worm gear shaft. The gland is connected with a hand wheel. The coil cable limit device for the mobile equipment has a reasonable structure design and occupies a small space. The worm gear and worm transmission mode is adopted and the cam is adopted to turn on the limit switch, so the coil cable limit device has safe and reliable performance, is particularly suitable for the underground equipment and has a high using value.
