Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of concrete production equipment, specifically to a shock-absorbing device with a double-sided protective structure. Background Technology
[0002] During the concrete production process, the mixer will generate strong vibrations and impacts. These vibrations and impacts not only affect the stability and service life of the equipment, but also the vibration damping equipment absorbs and disperses the vibrations and impacts through the cooperation of bladder dampers and other damping components, thereby reducing their impact on equipment and personnel.
[0003] In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: 1. When the equipment is working, since most of the equipment only performs simple vertical shock absorption at the bottom, the horizontal vibration will affect the stability of the equipment when the equipment is horizontally vibrating, resulting in unstable operation of the equipment; 2. When the equipment is fixed, most of the shock absorption components on the equipment are fixed, which makes it impossible to effectively fix some equipment of different heights, resulting in poor versatility of the equipment. Utility Model Content
[0004] The purpose of this utility model is to provide a shock-absorbing device with a double-sided protective structure to solve the problems mentioned in the background art, namely, the inability of the device to perform horizontal shock absorption and the inability to adjust the position of the shock-absorbing components. To achieve the above objective, this utility model provides the following technical solution: a shock-absorbing device with a double-sided protective structure, comprising a base, an air spring installed at the bottom of the base, an AC motor installed on one side of the base, a threaded rod connected to one side of the AC motor, a lifting base threadedly connected to the threaded rod, a servo motor installed at the upper end of the lifting base, a rotating rod connected to the bottom of the servo motor, a sliding block threadedly connected to the rotating rod, a pneumatic base installed on one side of the sliding block, a telescopic cylinder provided on one side of the pneumatic base, a damping spring installed on one side of the telescopic cylinder, an elastic support plate installed on one side of the damping spring, and a protective block installed on one side of the elastic support plate.
[0005] More preferably, the airbag springs are symmetrically installed about the transverse centerline of the body base.
[0006] More preferably, the lifting base forms a sliding structure through the cooperation of an AC motor and a threaded rod.
[0007] More preferably, the pneumatic base forms a lifting structure through the cooperation of a rotating rod and a sliding block.
[0008] In a further preferred embodiment, the damping spring forms a telescopic structure through the cooperation of the pneumatic base and the telescopic cylinder.
[0009] More preferably, the damping springs are symmetrically installed about the transverse centerline of the elastic support plate.
[0010] More preferably, the protective blocks are evenly arranged along one side of the elastic support plate.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] In this invention, a damping spring and an elastic support plate are added. When the device is working, the air in the airbag at the bottom of the machine base is compressed, and at the same time, the internal buffer piston and the oil in the cavity slow down the compression speed of the load, release kinetic energy and reduce vibration. Meanwhile, the damping spring on one side of the telescopic cylinder will deform to store energy, and the oil in the damper will flow to generate a resistance opposite to the direction of movement, which will hinder the movement of the spring, reduce the vibration and impact of the spring, and reduce vibration, thus buffering the horizontal vibration of the device.
[0013] In this invention, a threaded rod and a rotating rod are added. When the device is fixing devices at different heights, the AC motor drives the threaded rod to rotate, which in turn drives the lifting base to slide, thereby adjusting the position of the bilateral shock absorber laterally. Then, the servo motor drives the rotating rod to rotate, which in turn drives the sliding block and the pneumatic base to slide, thereby adjusting the height of the bilateral shock absorber, so that the device can fix devices at different heights.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figures 1 to 4 This utility model provides a technical solution: a shock-absorbing device with a double-sided protective structure, including a base 1, an air spring 2 installed at the bottom of the base 1, an AC motor 3 installed on one side of the base 1, a threaded rod 4 connected to one side of the AC motor 3, a lifting base 5 threadedly connected to the threaded rod 4, a servo motor 6 installed at the upper end of the lifting base 5, a rotating rod 7 connected to the bottom of the servo motor 6, a sliding block 8 threadedly connected to the rotating rod 7, a pneumatic base 9 installed on one side of the sliding block 8, a telescopic cylinder 10 provided on one side of the pneumatic base 9, a damping spring 11 installed on one side of the telescopic cylinder 10, an elastic support plate 12 installed on one side of the damping spring 11, and a protective block 13 installed on one side of the elastic support plate 12.
[0021] In this embodiment, as Figure 1 and Figure 2 As shown, the airbag springs 2 are symmetrically installed about the transverse centerline of the machine base 1. By installing the airbag springs 2 at the bottom of the machine base 1, when the equipment vibrates, the air in the airbag is compressed, generating a reaction force to resist the compression of the load. At the same time, the internal buffer piston and the oil in the cavity slow down the compression speed of the load and release kinetic energy to reduce vibration.
[0022] In this embodiment, as Figure 1 and Figure 3 As shown, the lifting base 5 forms a sliding structure through the cooperation of the AC motor 3 and the threaded rod 4; by installing the lifting base 5 on one side of the threaded rod 4, the AC motor 3 drives the threaded rod 4 to rotate, thereby driving the lifting base 5 to slide, and adjusting the position of the bilateral shock absorber laterally.
[0023] In this embodiment, as Figure 1 and Figure 4 As shown, the pneumatic base 9 forms a lifting structure through the cooperation of the rotating rod 7 and the sliding block 8; by installing the sliding block 8 on one side of the rotating rod 7, the servo motor 6 drives the rotating rod 7 to rotate, thereby driving the sliding block 8 to slide with the pneumatic base 9, thus adjusting the height of the double-sided shock absorber.
[0024] In this embodiment, as Figure 1 , Figure 2 and Figure 4As shown, the damping spring 11 forms a telescopic structure through the cooperation of the pneumatic base 9 and the telescopic cylinder 10. By installing the damping spring 11 on one side of the telescopic cylinder 10, the pneumatic base 9 drives the telescopic cylinder 10 to extend and retract through air pressure, thereby driving the damping spring 11 to extend and retract. Adjusting the distance of the damping spring 11 facilitates the clamping of the equipment.
[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, the damping springs 11 are symmetrically installed about the transverse centerline of the elastic support plate 12. By installing the damping springs 11 on one side of the elastic support plate 12, when the equipment vibrates, the springs will first deform to store energy. At the same time, the oil in the damper will flow and generate a resistance opposite to the direction of movement to hinder the movement of the springs, thereby reducing the vibration and impact of the springs and maintaining stability.
[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, the protective blocks 13 are evenly arranged along one side of the elastic support plate 12. When the telescopic cylinder 10 drives the elastic support plate 12 to extend and retract, the elastic support plate 12 bends to cooperate with the protective blocks 13, so as to fit against the surface of the equipment and protect the surface of the equipment. At the same time, the protective blocks 13 prevent the equipment from slipping.
[0027] The usage method and advantages of this utility model: The shock absorption device with a double-sided protective structure operates as follows:
[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the device is first placed on the base 1 of the machine body using an external hoist. Then, the AC motor 3 drives the threaded rod 4 to rotate, which in turn drives the lifting base 5 to slide, thereby adjusting the position of the bilateral shock absorber laterally. Then, the servo motor 6 drives the rotating rod 7 to rotate, which in turn drives the sliding block 8 to slide against the pneumatic base 9, thereby adjusting the height of the bilateral shock absorber so that it can fix devices of different heights. When the device on the base 1 vibrates during operation, the air in the airbag at the bottom of the base 1 is compressed, and the internal buffer piston and the oil in the cavity slow down the compression speed of the load, releasing kinetic energy for shock absorption. At the same time, the damping spring 11 on one side of the telescopic cylinder 10 deforms to store energy, and the oil in the damper flows, generating a resistance opposite to the direction of movement to hinder the movement of the spring, thereby reducing the vibration and impact of the spring, thus damping the horizontal vibration of the device and increasing its service life.
[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
