Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of coal crushers, in particular to a vibration reduction platform for coal crushers. Background Art
[0002] Coal pulverizer, referred to as coal crusher, is one of the commonly used equipment in crushing coal and crushing coal gangue production lines. Coal pulverizer is improved on the basis of the old hammer crusher and is a new type of coal pulverizer with a new structure.
[0003] Existing coal crushers generate vibration during operation. To reduce the impact of this vibration, a vibration-damping platform is often installed at the bottom of the equipment. Most existing vibration-damping platforms consist of a base, a carrier plate, and a damper. The damper is installed longitudinally between the carrier plate and the base. Although the damper can absorb vibration, the longitudinal distribution of the damper only absorbs vibration in one direction, resulting in limited vibration absorption and thus poor vibration reduction. Therefore, we propose a vibration-damping platform for coal crushers. Utility Model Content
[0004] The purpose of the utility model is to provide a vibration reduction platform for a coal crusher, which solves the problems raised in the background technology.
[0005] To achieve the above object, the utility model provides the following technical solution: a vibration reduction platform for a coal crusher, comprising a base, vibration reduction assemblies fixed to both sides of the top of the base, a carrier plate connected to the top of the vibration reduction assembly, and a connecting plate connected to the top of the carrier plate;
[0006] The vibration damping assembly includes a fixed plate, a limiting slot is provided on the top of the fixed plate, and adaptive limiting sliders are inserted on both sides of the inner cavity of the limiting slot. A damper is fixed to one side wall of the limiting slider, and the outer end of the damper is fixedly connected to the inner wall of the limiting slot. A connecting rod is hinged on the top of the limiting slider, and the outer end of the connecting rod is hinged to the bottom of the carrier plate.
[0007] By adopting the above technical solution, the coal crusher and the connecting plate are first connected and fixed. Then, during use, the vibration generated by the coal crusher is transmitted to the carrier plate, and the carrier plate transmits the vibration to the connecting rod, so that the connecting rod acts on the limit slider, and thus acts on the damper. The dampers distributed on both sides can be used for shock absorption. The impact force caused by the vibration transmitted by the connecting rod allows the force to be decomposed, thereby reducing the force acting on the damper, thereby improving the vibration reduction and buffering effect, and at the same time protecting the damper and extending its service life.
[0008] As a preferred embodiment of the present invention, a first damping spring is provided in the inner cavity of the limiting sliding groove, and both ends of the first damping spring are fixedly connected to the two side walls of the limiting sliding block respectively.
[0009] By adopting the above technical solution and setting the damping spring, the limit slider can be pulled or pushed back when it moves, further improving the buffering effect.
[0010] As a preferred embodiment of the present invention, a first magnet block is fixed at the middle of the bottom of the carrier plate, and a second magnet block is fixed at the top of the base corresponding to the first magnet block.
[0011] As a preferred embodiment of the present invention, limiting rods are fixed on the four sides of the top of the base, and the limiting rods are movable through the carrier plate. The outer wall of the limiting rods is provided with a second damping spring, and the two ends of the second damping spring are respectively fixedly connected to the bottom of the carrier plate and the top of the base.
[0012] As a preferred embodiment of the present invention, connection holes are provided at the four corners of the top of the connection plate.
[0013] By adopting the above technical solution and setting the connection holes, the connection plate can be conveniently connected and fixed to the coal crusher.
[0014] As a preferred embodiment of the present invention, mounting holes are provided at the four corners of the top of the base.
[0015] By adopting the above technical solution and setting the mounting holes, it is convenient to install and fix the entire device.
[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0017] The technical solution of the present application is a vibration reduction platform for a coal crusher. Two dampers are arranged in the vibration reduction assembly. The two dampers are laterally distributed on both sides. Therefore, when vibration is generated, the limiting slider can be driven to slide in the limiting slide groove by the connecting rod, so that the dampers on both sides are used for vibration absorption and buffering. At the same time, the first damping spring is cooperated to expand and contract. The inclined setting of the connecting rod can decompose the force driven by the vibration, thereby reducing the force acting on the damper, which is conducive to improving the vibration reduction effect of the coal crusher, thereby helping to reduce the impact of vibration on the coal crusher and protecting the damper at the same time.
[0018] By arranging a first magnet block at the bottom of the carrier plate and a second magnet block at the top of the base, and then cooperating with a second damping spring, when the carrier plate is vibrated and drops, the principle of opposite poles repelling each other between the first magnet block and the second magnet block can be used to buffer and reduce vibration again, which can help to further improve the vibration reduction effect.

[0027] See also Figure 1-3 The utility model provides a technical solution: a vibration reduction platform for a coal crusher, comprising a base 1, vibration reduction components 2 are fixed on both sides of the top of the base 1, the top of the vibration reduction component 2 is connected to a carrier plate 3, and the top of the carrier plate 3 is connected to a connecting plate 31;
[0028] The vibration damping assembly 2 includes a fixed plate 21, a limiting slot is defined at the top of the fixed plate 21, and matching limiting sliders 22 are inserted into both sides of the inner cavity of the limiting slot. A damper 23 is fixed to one side wall of the limiting slider 22, and the outer end of the damper 23 is fixedly connected to the inner wall of the limiting slot. A connecting rod 25 is hinged to the top of the limiting slider 22, and the outer end of the connecting rod 25 is hinged to the bottom of the carrier plate 3.
[0029] During actual use, the coal crusher and the connecting plate 31 are first connected and fixed. Then, during use, the vibration generated by the coal crusher is transmitted to the carrier plate 3, and the carrier plate 3 transmits the vibration to the connecting rod 25, so that the connecting rod 25 acts on the limit slider 22, and thus acts on the damper 23. The dampers 23 distributed on both sides can be used for shock absorption. The impact force caused by the vibration transmitted by the connecting rod 25 can be decomposed, thereby reducing the force acting on the damper 23, thereby improving the vibration reduction and buffering effect, and at the same time protecting the damper 23 and extending its service life.
[0030] Furthermore, mounting holes 12 are provided at the four corners of the top of the base 1. The provision of the mounting holes 12 facilitates the installation and fixation of the entire device.
[0031] Furthermore, connection holes 32 are provided at the four corners of the top of the connection plate 31. The arrangement of the connection holes 32 makes it convenient to connect and fix the connection plate 31 to the coal crusher.
[0032] It is worth mentioning that limiting rods 11 are fixed on the four sides of the top of the base 1, and the limiting rods 11 are movable through the carrier plate 3. The setting of the limiting rods 11 enables the lifting and lowering trajectory of the carrier plate 3 to be limited, thereby preventing the carrier plate 3 from deflecting during vibration lifting and lowering, and further avoiding damage to the connecting rod 25.
[0033] like Figure 1 and 2 As shown; a first damping spring 24 is provided in the inner cavity of the limiting slide groove, and the two ends of the first damping spring 24 are fixedly connected to the side walls of the two limiting sliders 22 respectively. The setting of the first damping spring 24 enables the limiting slider 22 to be pulled or pushed back when it moves, further improving the buffering effect.
[0034] like Figure 1 and 3 As shown; a first magnet block 33 is fixed at the middle of the bottom of the carrier plate 3, a second magnet block 13 is fixed at the top of the base 1 corresponding to the first magnet block 33, and a second damping spring 14 is sleeved on the outer wall of the limit rod 11, and the two ends of the second damping spring 14 are fixedly connected to the bottom of the carrier plate 3 and the top of the base 1 respectively;
[0035] When the carrier plate 3 is vibrated and falls, the first magnet block 33 and the second magnet block 13 are used to repel opposite poles to perform buffering and vibration reduction, thereby further improving the vibration reduction effect.
[0036] The implementation principle of the vibration reduction platform for a coal crusher in the present application is as follows: in actual use, the coal crusher and the connecting plate 31 are first connected and fixed, and then during use, the vibration generated by the coal crusher is transmitted to the carrier plate 3, and the carrier plate 3 will transmit the vibration to the connecting rod 25, so that the connecting rod 25 will act on the limit slider 22, and thus act on the damper 23, and the dampers 23 distributed on both sides can be used for shock absorption, and the impact force caused by the vibration transmitted by the connecting rod 25 can be decomposed, thereby reducing the force acting on the damper 23, thereby improving the vibration reduction and buffering effect, and at the same time playing a role in protecting the damper 23 and extending its service life. When the carrier plate 3 is vibrated and dropped, the principle of opposite repulsion between the first magnet block 33 and the second magnet block 13 is used to buffer and reduce vibration again, and the second damping spring 14 can be used to buffer the rebound formation, which can help to improve the vibration reduction effect again.
[0037] In addition, the components included in the vibration reduction platform for a coal crusher of the present invention are all universal standard parts or components known to technical personnel in this field. The structure and principle thereof can be known to technical personnel in this field through technical manuals or through conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and adaptive monitoring computers and power supplies, are connected through wires.
