Description
Technical Field
The utility model belongs to the technical field of elevator equipment, concretely relates to mining elevator wire rope detection device.
Background
An elevator is a transportation device that transports pedestrians or goods vertically. Modern elevators are mainly composed of a traction machine (winch), guide rails, a counterweight, safety devices (such as a speed limiter, a safety gear, a buffer and the like), a signal control system, a steel wire rope, a car, a hall door and the like. These parts are installed in the hoistway and machine room of the building, respectively. The elevator usually adopts steel wire rope friction transmission, and wire rope walks around the driving sheave, and both ends are connected car and balancing weight respectively, and the motor drives the driving sheave and makes the car go up and down.
The main problems and drawbacks of the prior art include:
because the tonnage of the mine elevator is large, the hoisting height is high, the steel wire rope is easy to stretch and lengthen, the buffer distance on the counterweight side is reduced after the steel wire rope is structurally stretched, and the elevator is possibly stopped due to the elevator fault because the counterweight is upset onto the buffer before the top floor leveling; after the steel wire rope extends, the positions of the lower limit switch and the lower limit switch are also changed by the counterweight side impact bow, and the end station limit protection cannot be realized; after the steel wire rope is stretched, the compensation chain is easily dragged to the ground, the weight of the steel wire rope cannot be compensated, the running stability of the elevator can be seriously influenced, and the safety of passengers is endangered.
SUMMERY OF THE UTILITY MODEL
To the above-mentioned problem and the defect that exist among the prior art, the utility model provides a mining elevator wire rope detection device can whether automated inspection wire rope has been stretched, has improved mining elevator's security, and the installation is simple, and convenient to use is reliable.
Therefore, the utility model adopts the following technical scheme:
a mining elevator steel wire rope detection device is positioned on one side of a counterweight in a well of a mining elevator and comprises a detection switch bracket, a steel wire rope detection switch, a collision bow and a collision bow bracket; the detection device is arranged on one side of the counterweight straight beam, the collision bow is fixed on the counterweight straight beam through a collision bow support, the steel wire rope detection switch is arranged on a detection switch support, and the position of the detection switch support is fixed near the region away from the bottom layer flat layer.
Preferably, the detection switch bracket adopts a position which is 100-150mm away from the bottom floor horizontal layer of the pressing code fixing guide rail.
Preferably, the wire rope detection switch is connected to an input terminal of the controller.
Compared with the prior art, the beneficial effects of the utility model are that:
(1) the device improves the safe and reliable operation of the mining elevator and eliminates the potential safety hazard of abnormal starting of the elevator.
(2) Simple installation and low manufacturing cost.
(3) The detection method is simple, accurate and reliable.

Description of reference numerals: 1. a detection switch bracket; 2. a steel wire rope detection switch; 3. knocking the bow; 4. a bow-hitting bracket; 5. a counterweight straight beam; 6. pressing codes; 7. a guide rail; 8. a car; 9. the bottom layer is flat.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments, which are only used for explaining the present invention, but not for limiting the present invention.
As shown in fig. 1 and 2, the utility model discloses a mining elevator wire rope detection device, which is positioned at one side of a counterweight in a mining elevator well and comprises a detection switch bracket 1, a wire rope detection switch 2, a striking bow 3 and a striking bow bracket 4; the detection device is arranged on one side of a counter-weight straight beam 5, the collision bow 3 is fixed on the counter-weight straight beam 5 through a collision bow support 4, the steel wire rope detection switch 2 is arranged on a detection switch support 1, and the position of the detection switch support 1 is fixed near a bottom floor layer.
Specifically, the detection switch bracket 1 adopts a position where a pressing code fixing guide rail is 100-150mm away from the bottom floor horizontal layer.
Specifically, the wire rope detection switch 2 is connected to an input terminal of the controller.
Examples
A mining elevator steel wire rope detection device is positioned on one side of a counterweight in a well of a mining elevator and comprises a detection switch bracket 1, a steel wire rope detection switch 2, a collision bow 3 and a collision bow bracket 4; the detection device is arranged on one side of a counterweight straight beam 5, the collision bow 3 is fixed on the counterweight straight beam 5, the steel wire rope detection switch 2 is arranged on the detection switch bracket 1, and the position of the steel wire rope detection switch is fixed at the position which is 150mm away from the bottom floor flat layer area 100-. The detection switch bracket 1 is provided with a pressing code 6, and a guide rail 7 is arranged below the impact bow bracket 4 above the middle part of the pressing code 6.
When the elevator runs to the bottom flat floor 9, the steel wire rope detection switch 2 arranged on one side of the counterweight is disconnected under the action of the impact bow 3, the steel wire rope detection switch 2 is connected to an input terminal of the control programmable controller, and through program control detection, if the steel wire rope is lengthened to exceed 150mm, the steel wire rope detection switch 2 cannot be contacted with the impact bow 3 on one side of the counterweight when the elevator is at the bottom flat floor 9, and at the moment, the steel wire rope detection switch 2 is in a closed state. The programmable controller can judge whether the steel wire rope is stretched or not through the on-off state of the switch, the buzzer in the car 8 can give an alarm after the stretching of the steel wire rope exceeds the specified range, the safety indicator lamp on the control box flickers, maintenance personnel can be effectively reminded to rapidly solve the problem, and the normal operation of the elevator is not influenced by the abnormal problem at the moment.
The above description is only for the preferred embodiment of the present invention and should not be taken as limiting the invention, and any modifications, equivalent replacements, and improvements made within the spirit and principle scope of the present invention should be included within the protection scope of the present invention.
