AI Technical Summary
In existing cement production equipment, the non-rigid connection of the grinding roller system leads to poor stability of the grinding roller system, violent lateral vibration of the hydraulic cylinder, causing frequent damage to the displacement sensor, display errors and mechanical components, high maintenance costs, and affecting production.
A shock-proof displacement sensor device is designed to fix the displacement sensor on the vertical grinding housing through the car track and the universal fixed seat, and the linear motion of the displacement sensor is achieved by using the piston rod and the spring-driven pulley to avoid horizontal swing.
It effectively extends the service life of the displacement sensor, reduces the failure rate and maintenance costs, and improves the reliability and economical production.

Abstract
Description
Technical Field
[0001] The invention relates to the field of cement production equipment, in particular to a shockproof displacement sensor device. Background Art
[0002] The imported extraordinary raw material vertical abrasive layer thickness sensor is designed to be installed inside the hydraulic cylinder. Since the grinding roller and the yoke are non-rigidly connected, the grinding roller system has poor stability during production operation. In the unstable material layer and the late stage of wear, the pull rod and the cylinder vibrate greatly, especially the lateral vibration of the cylinder is severe, which causes the built-in material level meter to be frequently damaged. After the display error occurs, it can cause damage to mechanical parts, such as the pull rod unlimited lifting and breaking accident. The cylinder must be disassembled for repair, which has a serious impact on production and is expensive to repair. Summary of the invention
[0003] In order to solve the problems of the prior art, the present invention provides a shockproof displacement sensor device. The shockproof displacement sensor of the trolley hardly generates horizontal swing, which effectively prolongs the service life of the displacement sensor.
[0004] The present invention comprises a vertical mill shell and a hydraulic cylinder, a trolley track and a universal fixing seat fixed on the vertical mill shell, a displacement sensor is fixed on the universal fixing seat, the hydraulic cylinder is connected to a grinding roller pull rod through a piston rod, and a traction clamp is installed on the grinding roller pull rod; a movable trolley is connected to the trolley track, one side of the movable trolley is connected to the traction clamp through a steel wire rope, and the other side is connected to the displacement sensor, and the hydraulic cylinder, the steel wire rope and the trolley track are all kept parallel; the movable trolley is connected to the trolley track through a plurality of pulleys and a clamping pulley and slides on the track without gap.
[0005] As a further improvement, the clamping pulley on the movable trolley is installed on a swing arm, one end of the swing arm rotates around the axis on the trolley, and the other end is pressed on the trolley track through an adjustable spring.
[0006] The beneficial effects of the present invention are:
[0007] 1. This technology installs the displacement sensor outside the oil cylinder, i.e. on the vertical mill shell. The displacement change of the piston rod pulls the trolley that can only slide linearly on the guide rail with the spring-compressed pulley, and then drives the displacement sensor element to move to display the up and down displacement change of the piston rod, i.e. the change of the material layer inside the mill. The displacement sensor hardly produces horizontal swing, which effectively prolongs the service life of the displacement sensor.
[0008] 2. The transformation cost is low, the failure rate is low, the service life is long, and the replacement after damage is convenient and quick, the maintenance cost is low, and the impact on production is small. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Figure 1 It is a schematic diagram of the structure of the present invention. DETAILED DESCRIPTION
[0010] The present invention will be further described below in conjunction with the accompanying drawings.
