Description

Technical Field

[0001] The utility model relates to the technical field of centrifuges, in particular to a shock-absorbing chassis for centrifuges. Background Art

[0002] A centrifuge is a device that automatically discharges solid-liquid mixtures by separating them. After the material is fed into the drum through a feed pipe, the centrifugal force generated by high-speed rotation causes subsequent solid-liquid separation. A spiral is also provided inside the drum, and the speed difference between the drum and the spiral is used to push the solid objects toward the discharge port. The drum and the spiral are usually referred to as a drum assembly.

[0003] When the centrifuge is working, the high-speed rotation of the drum assembly will cause strong vibration. Therefore, the centrifuge usually adopts a shock-absorbing chassis to support the support surface. For example, in the patent application with the publication number CN 218654968U in the prior art, a bearing part supporting the drum assembly is provided on the upper surface of the chassis body, and at least four shock absorbers arranged at intervals are connected to the lower surface; wherein, the two end surfaces of the shock absorber are respectively an upper end surface and a lower end surface parallel to each other; and a connecting member is also included, and the chassis body and the shock absorber are detachably connected through the connecting member, and the lower surface of the chassis body and the upper end surface form a surface contact; and when the shock-absorbing chassis is vertically projected, the projection of the bearing part is located within the maximum figure formed by the shock absorbers at different positions connected in sequence. The utility model also discloses a centrifuge, including the shock-absorbing chassis as described above. Its beneficial effects are: the shock absorber is safe and reliable to install, and the installation is simple, and at the same time, it is beneficial to the stability of the centrifuge.

[0004] However, the bottom of the chassis lacks an adjustment mechanism, which easily causes the chassis to tilt when the installation ground is uneven, and when the chassis needs to be moved, a lifting device is required to move the chassis, thereby reducing the maneuverability of the chassis.

[0005] Therefore, it is necessary to provide a shock-absorbing chassis for a centrifuge to solve the above technical problems. Utility Model Content

[0009] Rollers, the rollers are fixedly mounted at two ends of the bottom of the two reinforcing beams respectively;

[0010] The threaded rings are fixedly mounted on the four sides of the top of the top plate, the internal threads of the threaded rings are connected to a threaded rod, the bottom of the threaded rod is rotatably connected to a mounting sleeve, a shock absorber is arranged inside the mounting sleeve, and a pad is fixedly mounted on the bottom of the shock absorber.

[0011] Preferably, a rotating handle is fixedly mounted on the top of the threaded rod.

[0018] The utility model provides a shock-absorbing chassis for a centrifuge, which cooperates with each other through structures such as a top plate, a reinforcing beam, a supporting beam, a roller, a threaded ring, a threaded rod, a mounting sleeve, a shock absorber and a pad. When in use, the threaded rod is threadedly connected to the inner side of the threaded ring, so that the bottom of the threaded rod drives the pad to move downward.

DETAILED DESCRIPTION

[0024] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0025] First embodiment

A shock-absorbing chassis for a centrifuge, comprising: a top plate 1, support beams 12 are fixedly installed on both sides of the bottom of the top plate 1, reinforcing beams 11 are fixedly installed at both ends of the middle of the two support beams 12, and through holes 13 are opened inside the two ends of the two support beams 12;

[0027] Rollers 2, the rollers 2 are fixedly mounted at both ends of the bottom of the two reinforcing beams 11;

[0028] The threaded rings 3 are fixedly mounted on the four sides of the top of the top plate 1, the internal threads of the threaded rings 3 are connected to a threaded rod 31, the bottom of the threaded rod 31 is rotatably connected to a mounting sleeve 33, a shock absorber 34 is arranged inside the mounting sleeve 33, and a pad 35 is fixedly mounted on the bottom of the shock absorber 34.

[0029] A rotating handle 32 is fixedly mounted on the top of the threaded rod 31 .

[0030] The shock absorber 34 is disposed on the inner side of the through hole 13 , and the inner diameter of the through hole 13 is greater than the outer diameter of the mounting sleeve 33 .

[0031] Locking screws 37 are disposed inside both ends of the top of the mounting sleeve 33 , and the bottom of the locking screws 37 is threadedly connected to the top of the shock absorber 34 .

[0032] A rubber pad 36 is disposed at the bottom of the pad 35 .

[0033] When the shock absorber 34 needs to be disassembled, the user can rotate the locking screw 37 to make the bottom of the locking screw 37 threadedly connected from the top of the shock absorber 34, and then the user can take the shock absorber 34 out of the inner side of the installation sleeve 33, so as to disassemble the shock absorber 34;

[0034] When the installation sleeve 33 moves up and down, the installation sleeve 33 can slide on the inner side of the through hole 13;

[0035] A rubber pad 36 is installed at the bottom of the pad 35, so that it can play an anti-slip role when in use.

[0036] The working principle of a shock-absorbing chassis for a centrifuge provided by the utility model is as follows:

[0037] When the ground is uneven during use, the user can rotate the handle 32, so that the handle 32 drives the threaded rod 31 to be threadedly connected to the inner side of the thread ring 3, so that the bottom of the threaded rod 31 drives the mounting sleeve 33 to move downward, and when the mounting sleeve 33 moves downward, it drives the shock absorber 34 to move downward, so as to support the top plate 1 until the top plate 1 is adjusted to a horizontal state, and then the centrifuge is installed on the top of the top plate 1;

[0038] When the centrifuge needs to be moved, the user can rotate the multiple handles 32 respectively to move the pad 35 upward until the top of the pad 35 is in contact with the bottom of the support beam 12. At this time, the bottom of the roller 2 is in contact with the ground, so that the user can roll the roller 2 on the ground, thereby facilitating the user to move the position of the centrifuge.

[0039] Compared with the related art, the shock-absorbing chassis for a centrifuge provided by the utility model has the following beneficial effects:

[0040] The top plate 1, the reinforcing beam 11, the supporting beam 12, the roller 2, the threaded ring 3, the threaded rod 31, the mounting sleeve 33, the shock absorber 34 and the pad 35 and other structures cooperate with each other. When in use, the threaded rod 31 is threadedly connected to the inner side of the threaded ring 3, so that the bottom of the threaded rod 31 drives the pad 35 to move downward. In this way, when in use, the level of the top plate 1 can be adjusted to avoid the centrifuge tilting again due to uneven ground, and the roller 2 rolls on the ground, so that the user can move the position of the centrifuge conveniently.

[0044] The nut 42 is disposed on the top of the backing plate 35 .

[0045] The working principle of a shock-absorbing chassis for a centrifuge provided by the utility model is as follows:

[0046] After long-term use, when the rubber pad 36 is severely worn and needs to be replaced, the user can rotate the nut 42 to make the nut 42 threadedly connected to the outer side of the bolt 41. The user can then remove the bolt 41 from the inner side of the through groove 4, thereby making the rubber pad 36 contact the bottom of the pad 35.

[0047] Compared with the related art, the shock-absorbing chassis for a centrifuge provided by the utility model has the following beneficial effects:
