Description

Technical Field

[0001] The utility model belongs to the technical field of shock absorption and buffering, and particularly relates to a shock absorption and buffering component of a high-speed transfer platform. Background Art

[0002] The high-speed transfer platform can greatly improve the transfer efficiency of articles and is thus more widely adopted. When an article vibrates, the vibration generates a large amount of energy. When the energy directly acts on the article, it may cause damage to the article, especially fragile articles. An additional shock absorption and buffering mechanism on the transfer platform can absorb and disperse the vibration energy, reduce the vibration transmitted to the article, and thus protect the safety of the article during transfer. In the prior art, for the additional shock absorption and buffering mechanism, the shock absorption and buffering effect cannot meet the use requirements of the high-speed transfer platform. During vibration, the movement amplitude of the transfer platform is too large and the recovery performance is poor. In addition, due to foreign objects entering, faults are likely to occur. Content of the Utility Model

[0003] To solve the problems existing in the prior art, the utility model provides a shock absorption and buffering component of a high-speed transfer platform.

[0004] The technical solution adopted by the utility model to solve its technical problems is as follows: The shock absorption and buffering component of the high-speed transfer platform includes: an upper plate and a bottom plate. The upper plate is located above the bottom plate and moves up and down relative to the bottom plate. A damping column and a telescopic frame are arranged between the upper plate and the bottom plate. The damping columns are symmetrically distributed on the bottom plate, and the symmetry plane is the longitudinal section of the upper plate. The upper half of the damping column is fixedly installed at the bottom of the upper plate, and the lower half is fixedly installed on the bottom plate. The telescopic frame includes: a first rod and a second rod that are cross-set. One end of the first rod and the second rod is respectively hinged to the bottom of the upper plate, and the other end is hinged to the bottom plate. The first rod and the second rod are hinged through an intermediate shaft.

[0005] Further, the telescopic frames are symmetrically distributed on the bottom plate, and the symmetry plane is the longitudinal section of the upper plate.

[0006] Further, a first fixed seat and a second fixed seat are fixedly arranged on the bottom plate. A lower optical rod is arranged between the first fixed seat and the second fixed seat. A lower slider and a lower spring are sleeved on the lower optical rod, and the lower spring is located between the lower slider and the second fixed seat. A third fixed seat and a fourth fixed seat are fixedly arranged at the bottom of the upper plate. An upper optical rod is arranged between the third fixed seat and the fourth fixed seat. An upper slider and an upper spring are sleeved on the upper optical rod, and the upper spring is located between the upper slider and the fourth fixed seat. One end of the first rod is hinged to the first fixed seat, and the other end is hinged to the upper slider. One end of the second rod is hinged to the third fixed seat, and the other end is hinged to the lower slider.

[0007] Further, an intermediate damping is provided, and the intermediate damping is arranged at the second fixed seat.

[0008] Further, the damping column includes: an outer column, an inner column, and an inner spring. The inner column is nested and connected with the outer column, and the inner spring is placed between the inner column and the outer column. When the inner spring is in its natural state, the height of the damping column is the maximum.

[0009] Further, vertical guide grooves are formed on the inner side of the outer column, and vertical convex ribs are provided on the outer side of the inner column. The convex ribs are installed in cooperation with the guide grooves.

[0010] Further, the damping column is arranged near the corner or edge of the bottom plate.

[0011] Further, the internal contour size of the upper plate is larger than the external contour size of the bottom plate.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: By adopting the combined setting of the damping column and the telescopic frame and improving the layout structure, the damping column and the telescopic frame work together, and the shock-absorbing and buffering assembly has a better effect of absorbing and dispersing vibration energy. When encountering vibration, the movement amplitude of the transfer platform is limited; the compressed inner spring can recover by itself, and the assembly returns to its original state accordingly; in the telescopic frame, by setting the lower smooth rod and the upper smooth rod, the friction during the movement is reduced, so that the telescopic frame moves up and down more smoothly and absorbs and disperses vibration energy quickly; the fixed ends and movable ends of the first rod and the second rod are defined, restricting the movement of the telescopic frame. When the shock-absorbing and buffering assembly works, except for moving up and down relative to the bottom plate, the upper plate does not change in other directions; with the setting of the lower spring and the upper spring, when the telescopic frame moves downward, it is compressed to disperse part of the energy, playing a shock-absorbing role, and then driving the second rod and the first rod to recover respectively, accelerating the recovery of the shock-absorbing and buffering assembly; in the damping column, the convex ribs are installed in cooperation with the guide grooves, further restricting the relative movement path in the damping column and improving the structural stability of the shock-absorbing and buffering assembly during operation; the internal contour size of the upper plate is larger than the external contour size of the bottom plate, which can effectively prevent dust or sundries from falling into the interior of the shock-absorbing and buffering assembly, thus avoiding the resulting failure problems. The shock-absorbing and buffering assembly operates in a relatively independent space, reducing the failure rate. Description of the Drawings

[0022] For the convenience of understanding the present utility model, the present utility model will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. However, the present utility model can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosed content of the present utility model more thorough and comprehensive.

[0023] Embodiment 1: In combination with Figures 1-3 Understand that the shock absorption and buffering assembly of the high-speed transfer platform includes: an upper plate 1 and a bottom plate 2. The upper plate 1 is located above the bottom plate 2, and the upper plate 1 moves up and down relative to the bottom plate 2. A damping column 3 and a telescopic frame 4 are provided between the upper plate 1 and the bottom plate 2. A plurality of damping columns 3 are symmetrically distributed on the bottom plate 2, and the symmetry plane is the longitudinal section at the middle position of the upper plate 1; the upper half of the damping column 3 is fixedly installed at the bottom of the upper plate 1, and the lower half is fixedly installed on the bottom plate 2; the telescopic frame 4 includes: a first rod 411 and a second rod 412 arranged crosswise. One end of the first rod 411 and the second rod 412 is hinged to the bottom of the upper plate 1 respectively, and the other end is hinged to the bottom plate 2. The first rod 411 and the second rod 412 are hinged through an intermediate shaft 413. The damping column 3 includes: an outer column 301, an inner column 302 and an inner spring 303. The inner column 302 is nested with the outer column 301, and the inner spring 303 is placed between the inner column 302 and the outer column 301. When the inner spring 303 is in the natural state, the height of the damping column 3 is the largest.

[0024] Description of the working process: The shock absorption and buffering component is applied to a high-speed transfer platform. The upper plate 1 serves as the tabletop of the transfer platform or is fixedly installed on the tabletop, and the bottom plate 2 serves as the base of the transfer platform or is fixedly installed on the base. During the transfer process, when encountering vibrations, in the damping column 3, the compression inner spring 303 is compressed, and the inner column 302 moves downward within the outer column 301, capable of absorbing and dissipating vibration energy; the telescopic frame 4 moves downward accordingly, dissipating energy through mechanical motion. The combined action of the damping column 3 and the telescopic frame 4 makes the shock absorption and buffering component better at absorbing and dispersing vibration energy, and the movement amplitude of the transfer platform is limited when encountering vibrations. The compressed inner spring 303 can recover on its own, and the component returns to its original state accordingly. Among them, the strength of the recovery ability is related to the number and layout of the damping columns 3.

[0025] The internal contour dimension of the upper plate 1 is larger than the external contour dimension of the bottom plate 2. Such a setting can effectively prevent dust or debris from falling into the interior of the shock absorption and buffering component, thereby avoiding malfunction problems caused thereby. The shock absorption and buffering component operates in a relatively independent space, reducing the failure rate.

[0026] Embodiment 2: The telescopic frame 4 includes: a first frame 414 and a second frame 415. The first frame 414 and the second frame 415 are symmetrically distributed on the bottom plate 2, and the symmetry plane is the longitudinal section at the middle position of the upper plate 1. The first fixed seat 401 and the second fixed seat 403 are fixedly provided on the bottom plate 2. The lower optical rod 402 is erected between the first fixed seat 401 and the second fixed seat 403. The lower slider 404 and the lower spring 405 are sleeved on the lower optical rod 402 and the lower spring 405 is located between the lower slider 404 and the second fixed seat 403; the third fixed seat 406 and the fourth fixed seat 408 are fixedly provided at the bottom of the upper plate 1. The upper optical rod 407 is erected between the third fixed seat 406 and the fourth fixed seat 408. The upper slider 409 and the upper spring 410 are sleeved on the upper optical rod 407 and the upper spring 410 is located between the upper slider 409 and the fourth fixed seat 408; one end of the first rod 411 is hinged to the first fixed seat 401, and the other end is hinged to the upper slider 409; one end of the second rod 412 is hinged to the third fixed seat 406, and the other end is hinged to the lower slider 404.

[0027] In the telescopic frame 4, by setting the lower optical rod 402 and the upper optical rod 407, the friction during the movement process is reduced, making the up and down movement of the telescopic frame 4 smoother and quickly absorbing and dispersing vibration energy; the fixed ends and movable ends of the first rod 411 and the second rod 412 are defined, restricting the movement of the telescopic frame 4. When the shock absorption and buffering component comes into play, in addition to moving up and down relative to the bottom plate 2, the upper plate 1 does not change in other directions; with the setting of the lower spring 405 and the upper spring 410, when the telescopic frame 4 moves downward, it is compressed to disperse part of the energy, playing a shock absorption role, and then will drive the second rod 412 and the first rod 411 to recover respectively, accelerating the recovery of the shock absorption and buffering component.

[0028] Embodiment 3: Further combination Figure 4 Understood in combination, on the basis of Embodiment 2, an intermediate damper 5 is provided, and the intermediate damper 5 is provided at the second fixed seat 403. That is to say, the upper half of the intermediate damper 5 replaces the fourth fixed seat 408, and the lower half replaces the second fixed seat 403. The upper half and the lower half of the intermediate damper 5 are respectively installed through the corresponding upper optical rod 407 and lower optical rod 402.

[0029] A new support is formed in the middle part, and the damping is increased, so that the shock absorption and buffering effect is better.

[0030] Embodiment 4: Combination Figure 5 Understood in combination, in the damping column 3, a vertical guide groove 304 is formed on the inner side of the outer column 301, and a vertical convex rib 305 is provided on the outer side of the inner column 302. The convex rib 305 is installed in cooperation with the guide groove 304. The path of relative movement in the damping column 3 is further restricted, and the structural stability during the operation of the shock absorption and buffering assembly is improved.

[0031] Generally, the damping column 3 is arranged near the corner or the edge of the bottom plate 2. The scattered arrangement is beneficial to absorb and disperse the vibration energy and achieve a better shock absorption effect.
