Description

Technical Field

[0001] The utility model relates to the technical field of engineering instrument measurement, in particular to a weight level meter. Background Art

[0002] The weight level meter is an instrument for detecting material level. It is generally used in scenarios where the detection environment is complex, the interference is large, or the solid level in the liquid needs to be monitored. The principle is that a rope is tied to a weight through a guide rope mechanism and falls vertically. When the weight touches an object, the guide rope mechanism receives a signal to retract the weight, and the height of the material level is calculated by measuring the rope stroke.

[0003] With the repeated use of the level meter, foreign objects often stick to the surface of the rope, causing the heavy hammer level meter to become stuck and fail during the rope reeling process, affecting the measurement effect and shortening the service life of the equipment.

[0026] The cleaning mechanism includes two groups of cleaning rollers 6 symmetrically arranged in the cleaning chamber 403. The two groups of cleaning rollers 6 are arranged to abut against each other. The steel wire rope 2 passes vertically between the two groups of cleaning rollers 6. Each group of cleaning rollers 6 is arranged opposite to each other. When the steel wire rope 2 rises or falls, its surface rubs against the cleaning roller 6. The surface of the cleaning roller 6 is provided with a brush, thereby achieving the effect of cleaning the surface of the steel wire rope 2.

[0027] In order to keep the two groups of cleaning rollers 6 in abutment with each other so as to clamp the wire rope 2, a mounting frame 7 is provided in the cleaning cylinder 4, and a plurality of connecting rods 8 are slidably provided on the mounting frame 7, and the cleaning rollers 6 are provided on the connecting rods 8, and a flexible abutting mechanism is provided between the mounting frame 7 and the connecting rods 8, and the flexible abutting mechanism is used to drive the two groups of cleaning rollers 6 to keep in abutment with each other; the flexible abutting mechanism includes an abutting boss 9 provided on the connecting rod 8, and a compression spring 10 is sleeved on the connecting rod 8, and the two ends of the compression spring 10 respectively abut the mounting frame 7 and the abutting boss 9.

[0028] One end of the connecting rod 8 passes through the mounting frame 7 and is provided with a limited end 11. One end of the connecting rod 8 is connected to the cleaning roller 6, and the other end passes through the mounting frame 7. The connecting rod 7 is slidably mounted on the mounting frame 7. Therefore, a limited end 11 is provided to limit the sliding distance of the connecting rod 7 on the mounting frame 7 toward the side of the cleaning roller 6 and prevent the connecting rod 7 from falling off.

[0029] In order to achieve a better cleaning effect, the side wall of the cleaning cylinder 4 is provided with a liquid inlet pipe 12 and a liquid outlet pipe 13 connected to the cleaning chamber 403, and a control valve 14 is provided on the liquid inlet pipe 12 and the liquid outlet pipe 13; cleaning liquid is injected into the cleaning chamber 403 through the liquid inlet pipe 12, so as to cooperate with the cleaning drum 6 to clean the wire rope 2.

[0031] Although the sealing ring 18 can prevent the cleaning liquid from leaking, the steel wire rope 2 needs to rise or fall, so when the steel wire rope 2 passes through the cleaning chamber 403, a small amount of cleaning liquid will still adhere to its surface. Therefore, a blowing mechanism is provided in the first blowing chamber 401 and the second blowing chamber 402; the blowing mechanism includes a jet valve 17 provided in the first blowing chamber 401 and the second blowing chamber 402 and located on both sides of the steel wire rope 2, and a fan 18 is provided on the side wall of the cleaning cylinder 4, and the fan 18 is connected to the jet valve 17 through an air pipe. The side wall of the cleaning cylinder 4 is also provided with a plurality of ventilation holes connected with the first blowing chamber 401; and the lower end of the cleaning cylinder 4 is provided with an opening connected with the second blowing chamber 402 for gas to flow out; when the wire rope 2 rises or falls, the jet valve 17 blows air to the wire rope 2, thereby drying the surface of the wire rope; in addition, in the process of collecting the rope, the jet valve 17 located in the second blowing chamber can first blow air to the surface of the wire rope 2, preliminarily blow off foreign matter attached to the surface of the wire rope 2, and then control the wire rope 2 to enter the cleaning chamber 403 for cleaning, thereby improving the cleaning efficiency.
