Description

Technical Field

[0001] The utility model relates to the technical field of monitoring devices, in particular to a safety monitoring device for a skip in a main shaft of a coal mine. Background Art

[0002] A skip is a container used directly in mines to load useful minerals, waste rock, coal or gangue. Existing mines all use vertical shaft skips to lift minerals.

[0003] After searching, the patent with announcement number: CN203728380U discloses a multi-space main shaft skip, including a skip body and a loading port located on the upper side of the skip body, the inner wall of the skip body is horizontally fixed with a U-shaped receiving frame, and the receiving frame and the bottom end of the loading port are on the same horizontal plane; the upper end surface of the receiving frame is provided with a movable load-bearing plate; the inner wall of the skip body located at the lower end of the loading port is connected with a movable flap. The upper space of the skip body is divided into passenger rooms by the movable load-bearing plate. When the auxiliary shaft winch fails or the main components are replaced, the staff go up and down the mine through the main shaft skip, ensuring the normal production of the mine. The loading space in the skip body can be enlarged or reduced by rotating the movable flap, and the volume can be changed to adapt to the loading of various minerals, thereby avoiding the safety needs of overloading the main shaft skip and meeting the needs of maximizing the capacity of the lifting equipment.

[0004] The technical solution has the following problems:

[0005] The inside of the skip cannot be monitored. If the coal in the skip is not completely unloaded and is directly reloaded, it may cause winch overload at the least and tank falling accident at the worst. At the same time, the coal in the skip cannot be sprayed with water. When it is hot, the material is easy to overheat and cause adverse effects. Utility Model Content

[0006] The purpose of the utility model is to solve the shortcomings in the prior art that the existing monitoring device cannot monitor the inside of the skip. If the coal in the skip is not completely unloaded, direct repeated loading may cause overloading of the winch at the least and a tank falling accident at the worst. At the same time, water cannot be sprayed on the coal in the skip. When it is hot, the material is easily overheated, causing adverse effects. A safety monitoring device for the skip of the main shaft of a coal mine is proposed.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A safety monitoring device for a skip in a main shaft of a coal mine, comprising a skip body, a loading port and an unloading port being provided on the skip body, a sensor for measuring the amount of coal stored in the skip body being provided inside the skip body, and the sensor being electrically connected to a main controller via wireless transmission;

[0009] A spraying mechanism is arranged on the top of the bucket body and is used for spraying water inside the bucket body.

[0010] In a possible design, the sensor is a laser ranging sensor installed at the loading port at an angle perpendicular to the floor.

[0011] In a possible design, the spraying mechanism includes a water tank, a water pump, a connecting pipe and a spraying plate, wherein the water tank is fixedly connected to the top of the bucket body, the water tank is provided with a water inlet pipe, the water pump is fixedly connected to the top of the bucket body, the input end of the water pump extends to the water tank, one end of the connecting pipe is fixedly connected to the output end of the water pump, the other end of the connecting pipe is fixedly connected to the spraying plate, and the spraying plate is installed on the top inner wall of the bucket body. A plurality of nozzles are provided at the bottom of the spraying plate.

[0012] In one possible design, a dust box is fixedly connected to the top of the water tank, a vacuum cleaner is fixedly connected to one side of the dust box, an input end of the vacuum cleaner extends into the dust box, a dust pipe is fixedly connected to the top of the dust box, a plurality of dust hoods are provided on the dust pipe, and a filter plate is provided in the dust box.

[0013] In a possible design, the number of the dust hoods is four, and the four dust hoods are distributed in a ring shape on the dust suction pipe.

[0014] In a possible design, the dust box is provided with a box door, and fixing plates are fixedly connected to the inner walls on both sides of the dust box. A bayonet is fixedly connected to the bottom of the filter plate, and a slot matching the bayonet is opened on the fixing plate.

[0015] In the present application, coal mine raw materials can be loaded into the skip body through the provided loading port, and the materials can be unloaded through the unloading port. Since a sensor is provided, and the sensor is a laser ranging sensor, the inside of the skip body can be monitored after unloading. When the data transmitted by the sensor is abnormal, it indicates that there is material that has not been completely unloaded inside the skip body, so that a signal will be transmitted to the main controller. After receiving the information, the material will not be loaded again, thereby avoiding adverse effects caused by repeated loading.

[0016] The water in the water tank can be pumped out through the water pump, and then transmitted to the spray plate through the connecting pipe, and finally sprayed out by the nozzle. In this way, when transporting materials with a lot of dust, water sprinkling can effectively reduce the dust. When transporting hot materials in a high temperature environment, water sprinkling can help cool the materials to prevent the materials from overheating during transportation. It can also help clean the inside of the bucket body.

[0017] By setting up a vacuum cleaner, the vacuum tube and the vacuum hood can generate suction, thereby absorbing some external dust and reducing the raising of dust.

[0018] The utility model can prevent adverse effects caused by repeated loading by real-time monitoring of the interior of the bucket body, and can spray water on the bucket body through a sprayer to reduce the raising of dust. BRIEF DESCRIPTION OF THE DRAWINGS
