Abstract
Description
Technical Field
[0001] This utility model relates to a shock-absorbing base for mining machinery, belonging to the field of mining machinery technology in the metallurgical industry. Background Technology
[0002] Mining machinery refers to machines directly used in mineral extraction and beneficiation operations. It includes mining machinery and mineral processing machinery. The working principles and structures of prospecting machinery are largely the same or similar to those of mining machinery used for extracting the same types of minerals; broadly speaking, prospecting machinery also belongs to the category of mining machinery. In addition, mining operations also utilize a large number of cranes, conveyors, ventilation fans, and drainage machinery. Currently, most mining machinery on the market generates significant vibrations during operation.
[0003] Existing vibration damping methods for mining machinery typically involve installing damping springs on the machinery to absorb vibrations. However, the damping structure relying solely on damping springs is relatively simple and the damping effect is not ideal. Therefore, we propose a vibration damping base for mining machinery. Utility Model Content
[0004] The purpose of this utility model is to provide a shock-absorbing base for mining machinery, which has a good shock absorption effect and solves the problems existing in the background technology.
[0005] The technical solution of this utility model is:
[0006] A shock-absorbing base for mining machinery includes a movable plate, a damping mechanism, and a shock-absorbing mechanism. The damping mechanism is located above the movable plate, and the shock-absorbing mechanism is located below the movable plate.
[0007] The damping mechanism includes a fixed plate, a piston tube, a sealing sleeve, a first piston, a moving rod, a sleeve, and a second piston. The fixed plate is fixed on top of the moving plate, and the piston tube is fixed on the fixed plate. A sealing sleeve is fitted onto the top of the piston tube. The piston tube contains a first piston and a second piston that are slidably connected to the inner wall of the piston tube. The first piston is located above the second piston. A moving rod is fixedly connected to the top of the first piston, and a sleeve is fixedly connected to the top of the moving rod. The sleeve is fitted onto the surface of the piston tube.
[0008] The shock absorption mechanism includes an abutment plate, a telescopic rod, and a support plate. The abutment plate is fixed below the movable plate, and the support plate is located below the abutment plate. A telescopic rod is provided between the abutment plate and the support plate, and a spring is sleeved on the telescopic rod.
[0009] The sleeve has an internal groove that is adapted to fit the piston tube.
[0010] The telescopic rod and the tower spring are fixedly connected at both ends to the contact plate and the support plate, respectively.
[0011] The support plate has extension plates on both sides that are movably connected to the support plate. Each extension plate is connected to the driven plate via a rotating rod. The driven plate is located between the abutment plate and the support plate.
[0012] The driven plate is provided with a slot that is adapted to the tower spring and the telescopic rod.
[0013] The beneficial effects of this utility model are as follows: During mechanical vibration, the fixed plate and the moving rod are pushed to move on the piston tube. The moving rod drives the first piston to move inside the piston tube. The first piston squeezes the hydraulic oil inside the piston tube and moves it to one end of the second piston through the gap between the second piston and the piston tube. When the amount of hydraulic oil at one end of the second piston increases, the resistance of the second piston increases, which will give the second piston a reaction force, so that the hydraulic oil is reset. The vibration force after being damped by the damping mechanism is transmitted to the moving plate. The moving plate pushes the contact plate to squeeze the tower spring. The tower spring performs secondary damping of the vibration force. Attached Figure Description

The slot on one side of the middle of one end of the support plate 33 facilitates the placement of the spring rod 34.
[0033] The working principle is as follows:
[0034] In use, the mining machinery is fixed to the upper part of the device via the connector 4. When the mining machinery moves downward due to its own weight, it pushes the moving plate 1 downward. The moving plate 1 presses the telescopic rod 32 and the tower spring 5 through the abutment plate 31. The abutment plate 31 contacts the driven plate 38, so that the abutment plate 31 and the driven plate 38 will not be damaged due to vibration. When the weight of the machinery exceeds a certain value, the tower spring 5 will continue to press, and the moving plate 1 will continue to move, pushing the driven plate 38 to move. The movement of the driven plate 38 pushes the extension plate 35 out of the support plate 33 through the rotating rod 37 and the fixing piece 36, thereby increasing the load-bearing area of the device.
[0035] When mechanical vibration occurs, the fixed plate 21 and the moving rod 25 are moved on the piston tube 22. The moving rod 25 drives the first piston 24 to move inside the piston tube 22. The first piston 24 squeezes the hydraulic oil inside the piston tube 22 and moves it to one end of the second piston 27 through the gap between the second piston 27 and the piston tube 22. When the amount of hydraulic oil at one end of the second piston 27 increases, the resistance of the second piston 27 increases, which will give the second piston 27 a reaction force to reset the hydraulic oil. When the vibration is large, the vibration force after being damped by the damping mechanism 2 is transmitted to the moving plate 1. The moving plate 1 pushes the abutment plate 31 to squeeze the tower spring 5. The tower spring 5 performs secondary damping of the vibration force, thereby greatly reducing the mechanical force.
