Abstract
Description
Technical Field
[0001] The present invention relates to a device for detecting the stability of a lifter and belongs to the technical field of lifters. Background Art
[0002] Currently, during the construction of tiling walls, it is necessary to first locate the bottommost tile. Therefore, usually some tile fragments are used for bedding and leveling. So, a lifter is often used to position the bottom tile. This device rotates and moves a screw ring outside the screw, thereby driving the support device to level the bottom of the tile.
[0003] After the existing lifter is produced, it is necessary to detect the stability of the device body to prevent the support device from tilting during the rising process, thereby affecting normal work. At the same time, due to the continuous friction between the screw ring and the screw, the friction force between the two increases, resulting in wear of the thread and reducing the service life of the lifter. Summary of the Invention
[0004] The purpose of the present invention is to provide a device for detecting the stability of a lifter. The structure of the present invention is simple and easy to use. It can detect the stability of the lifter during the rising process and at the same time add a lubricant to the outside of the screw, increasing the service life of the device, so as to solve the problems raised in the above background art.
[0005] To achieve the above purpose, the present invention provides the following technical solutions:
[0006] A device for detecting the stability of a lifter includes a base. A screw is fixedly connected to the top of the base. A screw ring is rotatably connected to the outside of the screw. A moving plate is movably connected to the top of the screw ring. A support frame is fixedly connected to the bottom of the moving plate. A guide rod is fixedly connected to the bottom of the support frame. An extrusion column is fixedly connected to one end of the guide rod located inside the base. A chute is provided on the inner wall of the base. A sliding rod is slidably connected to the inside of the chute. A force-receiving plate is fixedly connected to the end of the sliding rod away from the chute. A compression spring is fixedly connected to the top of the sliding rod. A push rod is fixedly connected to the bottom of the force-receiving plate. A cylinder is movably connected to the bottom of the push rod. A pressure sensor is fixedly connected to the outside of the cylinder. A display is fixedly connected to the outside of the base. A transmission rod is fixedly connected to the top of the force-receiving plate. An oil bladder is fixedly installed inside the base. An oil pipe is fixedly connected to the top of the oil bladder. An oil outlet cover is fixedly connected to the end of the oil pipe away from the oil bladder. Oil outlet holes are evenly provided at the bottom of the oil outlet cover.
[0007] Further, the screw is located at the center of the top of the base, and the moving plate is located directly above the screw ring.
[0008] Further, there are two support frames, symmetrically distributed at the bottom of the moving plate, and the number of guide rods is the same as that of the support frames.
[0009] Further, the bottom of the guide rod is movably connected to the inside of the base, and the chutes are symmetrically distributed on the inner wall of the base.
[0010] Further, one end of the compression spring away from the sliding rod is fixedly connected to the inner wall of the chute, and the extrusion columns are symmetrically distributed on the top of the force-bearing plate.
[0011] Further, the number of the push rods is the same as that of the cylinders, and the push rods and the cylinders are symmetrically distributed at the bottom of the force-bearing plate.
[0012] Further, the air pressure sensors are symmetrically distributed inside the base, and the air pressure sensors are electrically connected to the display.
[0013] Further, the transmission rods are evenly distributed on the top of the force-bearing plate, and the transmission rods are located directly below the oil bag.
[0014] Further, the oil pipe is located inside the screw rod, the oil outlet cover is located at the top of the screw rod, and the oil outlet holes are evenly distributed at the bottom of the oil outlet cover.
[0015] The beneficial effects of the present invention are as follows:
[0016] In the present invention, by providing a screw rod, the screw ring rotates on the outside of the screw rod at the top of the base, so that the screw rod moves. The movement of the screw ring drives the moving plate to move. Then, through the cooperation of the moving plate and the support frame, the work is carried out. The movement of the support frame drives the guide rod at its bottom to move. Through the cooperation of the guide rod and the extrusion column, when the extrusion column moves upward, the sliding rod drives the force-bearing plate to move upward under the action of the compression spring. If the support frame moves upward smoothly, the extrusion forces received by the force-bearing plate are the same at this time. When the support frame tilts, the forces received by the two push rods at the bottom of the force-bearing plate are different, so that the air pressure values in the two cylinders are different. Through the cooperation of the cylinders and the air pressure sensors, the air pressure values in the two cylinders are displayed on the display outside the base, so that the stability of the lifter can be detected. When the force-bearing plate moves upward driven by the sliding rod, the transmission rod on the top of the force-bearing plate moves at this time. The movement of the transmission rod squeezes the oil bag inside the base, so that the lubricant inside the oil bag enters the oil outlet cover at the top of the screw rod through the oil pipe. Then, through the cooperation of the oil outlet cover and the oil outlet holes at the bottom, the lubricant is sprayed onto the surface of the screw rod, achieving the effect of automatically adding lubricant and increasing the service life of the lifter.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0027] Please refer to Figures 1-7 , the present invention provides a technical solution:
[0028] Device for detecting the stability of a lifter, comprising a base 1, a screw rod 2 fixedly connected to the top of the base 1, a screw ring 3 rotatably connected to the outer side of the screw rod 2, a moving plate 4 movably connected to the top of the screw ring 3, the screw rod 2 being located at the exact center of the top of the base 1, the moving plate 4 being located directly above the screw ring 3, a support frame 5 fixedly connected to the bottom of the moving plate 4, a guide rod 6 fixedly connected to the bottom of the support frame 5, there being two support frames 5 symmetrically distributed at the bottom of the moving plate 4, the number of guide rods 6 being the same as the number of support frames 5, one end of the guide rod 6 located inside the base 1 being fixedly connected to a pressing column 7, a sliding groove 8 being formed on the inner wall of the base 1, the bottom of the guide rod 6 being movably connected inside the base 1, the sliding grooves 8 being symmetrically distributed on the inner wall of the base 1, a sliding rod 9 being slidably connected inside the sliding groove 8, one end of the sliding rod 9 away from the sliding groove 8 being fixedly connected to a force-receiving plate 10, one end of a compression spring 11 away from the sliding rod 9 being fixedly connected to the inner wall of the sliding groove 8, the pressing columns 7 being symmetrically distributed on the top of the force-receiving plate 10, the top of the sliding rod 9 being fixedly connected to the compression spring 11, the bottom of the force-receiving plate 10 being fixedly connected to a push rod 12, the bottom of the push rod 12 being movably connected to a cylinder 13, the number of push rods 12 being the same as the number of cylinders 13, and the push rods 12 and the cylinders 13 being symmetrically distributed at the bottom of the force-receiving plate 10, a pressure sensor 14 being fixedly connected to the outer side of the cylinder 13, a display 15 being fixedly connected to the outer side of the base 1. By providing the screw rod 2, the screw ring 3 rotates on the outer side of the screw rod 2 at the top of the base 1, thereby causing the screw rod 2 to move. The movement of the screw ring 3 drives the moving plate 4 to move. Then, through the coordinated use of the moving plate 4 and the support frame 5, the work is carried out. The movement of the support frame 5 drives the guide rod 6 at its bottom to move. Through the coordinated use of the guide rod 6 and the pressing column 7, when the pressing column 7 moves upward, the sliding rod 9 drives the force-receiving plate 10 to move upward under the action of the compression spring 11. If the support frame 5 moves upward smoothly, the extrusion forces received by the force-receiving plate 10 are the same at this time. When the support frame 5 tilts, the forces received by the two push rods 12 at the bottom of the force-receiving plate 10 are different at this time, so that the air pressure values inside the two cylinders 13 are different. Through the coordinated use of the cylinders 13 and the pressure sensors 14, the air pressure values inside the two cylinders 13 are displayed on the display 15 on the outer side of the base 1, so that the stability of the lifter can be detected.
[0029] The pressure sensors 14 are symmetrically distributed inside the base 1, and the pressure sensors 14 are electrically connected to the display 15. A transmission rod 16 is fixedly connected to the top of the force-bearing plate 10. An oil bladder 17 is fixedly installed inside the base 1. The transmission rods 16 are evenly distributed on the top of the force-bearing plate 10 and are located directly below the oil bladder 17. A tubing 18 is fixedly connected to the top of the oil bladder 17. One end of the tubing 18 away from the oil bladder 17 is fixedly connected to an oil outlet cover 19. Oil outlet holes 20 are evenly formed in the bottom of the oil outlet cover 19. The tubing 18 is located inside the screw rod 2, and the oil outlet cover 19 is located on the top of the screw rod 2. The oil outlet holes 20 are evenly distributed on the bottom of the oil outlet cover 19. By driving the force-bearing plate 10 to move upward under the drive of the slide bar 9, the transmission rod 16 on the top of the force-bearing plate 10 is moved at this time. By the movement of the transmission rod 16, the oil bladder 17 inside the base 1 is squeezed, so that the lubricant inside the oil bladder 17 enters the oil outlet cover 19 on the top of the screw rod 2 through the tubing 18, and then through the cooperation of the oil outlet cover 19 and the bottom oil outlet holes 20, the lubricant is sprayed onto the surface of the screw rod 2, achieving the effect of automatically adding lubricant and increasing the service life of the lifter.
[0030] The working principle of the present invention: By providing the screw rod 2, the screw ring 3 rotates on the outside of the screw rod 2 at the top of the base 1, so that the screw rod 2 moves. By the movement of the screw ring 3, the moving plate 4 is driven to move, and then through the cooperation of the moving plate 4 and the support frame 5, the work is carried out. By the movement of the support frame 5, the guide rod 6 at its bottom is driven to move. Through the cooperation of the guide rod 6 and the extrusion column 7, when the extrusion column 7 moves upward, the slide bar 9 drives the force-bearing plate 10 to move upward under the action of the compression spring 11. If the support frame 5 moves upward smoothly, the extrusion force received by the force-bearing plate 10 is the same at this time. When the support frame 5 is tilted, the forces received by the two push rods 12 at the bottom of the force-bearing plate 10 are different at this time, so that the air pressure values inside the two cylinders 13 are different. Through the cooperation of the cylinders 13 and the pressure sensors 14, the air pressure values inside the two cylinders 13 are displayed on the display 15 outside the base 1, so that the stability of the lifter can be detected. By driving the force-bearing plate 10 to move upward under the drive of the slide bar 9, the transmission rod 16 on the top of the force-bearing plate 10 is moved at this time. By the movement of the transmission rod 16, the oil bladder 17 inside the base 1 is squeezed, so that the lubricant inside the oil bladder 17 enters the oil outlet cover 19 on the top of the screw rod 2 through the tubing 18, and then through the cooperation of the oil outlet cover 19 and the bottom oil outlet holes 20, the lubricant is sprayed onto the surface of the screw rod 2, achieving the effect of automatically adding lubricant and increasing the service life of the lifter.
