Description

A mining hoist hoist speed detection device

technical field

The utility model relates to a mine hoist equipment, in particular to a mine hoist lifting speed detection device.

Background technique

The hoisting speed of the mine hoist does not meet the requirements, and the speed exceeds the standard value, which will lead to hoisting overwinding accidents, wire rope breakage accidents, and cage falling accidents, which will pose a great threat to personal safety. Therefore, the measurement, inspection and maintenance management of the lifting speed of the hoist is very important. At present, the measurement of the hoisting speed of the hoist is to use the tachometer to measure the motor shaft speed, and then use the speed ratio of the reducer and the hoist drum diameter to calculate the hoisting speed. Since the hoist drum diameter is large, At the operation site of the hoist, it is difficult to measure the diameter of the drum accurately, resulting in inaccurate measurement and calculation of the hoisting speed. In addition, at present, when measuring the lifting speed characteristic curve, the encoder or the speed measuring voltage sensor wheel is held by a human hand in direct contact with the hoist drum. Dangerous, the measured speed characteristic curve has a large error and cannot match the actual lifting distance. This is the weak point that existing technology exists.

Contents of the invention

The purpose of this utility model is to provide a technical solution for the detection device of the lifting speed of the mine hoist in view of the deficiencies in the prior art. , and can firmly fix the speed measuring mechanism without manual fixing, avoiding the occurrence of accidents. the

This program is realized through the following technical measures: a lifting speed detection device for a mining hoist, including a bracket on which a speed measuring mechanism is fixed. The feature of this program is: the bracket is U-shaped, and the The rolling device is fixed, the rolling device includes a fixed frame fixed on the bracket, an upper roller and a lower roller for clamping the wire rope are arranged in the fixed frame, and a compression spring is arranged between the upper roller and the fixed frame; the speed measuring The mechanism includes a speed measuring sensor, and the speed measuring sensor is connected with a controller, and the controller is connected with a wireless communication module.

The wireless communication module is a GPRS module or a GSM module or a zigbee module.

The bracket is provided with a plurality of fixing holes for fixing the bracket.

The controller described is a single-chip microcomputer.

The speed sensor is ZLS-Px speed sensor.

The fixed frame is U-shaped, one end of the fixed frame is fixed on the support, and the upper roller and the lower roller are both arranged in the frame.

The beneficial effect of this scheme can be known according to the narration of above-mentioned scheme, because in this scheme, there is a bracket that can be used for fixing the speed measuring mechanism; upper and lower rollers are arranged in the fixed frame, and the upper and lower rollers can be stuck on the wire rope, and There is a compression spring between the upper roller and the fixed frame, so that the wire rope can be clamped between the two rollers, and the two rollers are provided with rolling grooves to prevent the wire rope from detaching from the roller; there are fixed frames at both ends of the bracket, In this way, the speed measuring mechanism and the steel wire rope can be kept on the same plane when in use, which is beneficial to measure the moving speed of the steel wire rope; after the speed measuring sensor measures the speed, the controller controls the wireless communication module to send the speed information to the host computer, which is convenient for the staff to check, and Due to the use of the wireless transmission module, there is no need for staff to go to the scene to operate, so as to avoid accidents; there are fixing holes on the bracket, so that the bracket can be fixed to prevent the bracket from moving with the wire rope. It can be seen that, compared with the prior art, the utility model has substantive features and progress, and the beneficial effects of its implementation are also obvious.
