Abstract
Description
Technical Field
[0001] The utility model mainly relates to the technical field related to the transportation of sterilization vehicles, and in particular to a moving conveyor for sterilization vehicles. Background Art
[0002] During the transport of medical sterilization carts, a lifting and transporting machine is required. As a transport device for sterilization carts, the lifting and transporting machine works as follows: the sterilization cart first enters a fixed platform, then the lifting platform lifts the cart and transports it to the next workstation (or first enters a high-position lifting platform, then lowers the sterilization cart to the fixed platform, which then transports the sterilization cart to the next workstation).
[0003] Traditional lifting and moving machines primarily consist of a lifting platform, a fixed platform, and a rocker arm. The rocker arm is driven by a pneumatic cylinder fixed to the fixed platform. When the cylinder rod is pushed out, the rocker arm rotates, driving the lifting platform to achieve lifting and lowering motion. However, as the rocker arm is fixed to the lifting platform during rotation, the lifting platform's trajectory is not vertical, but rather follows the rocker arm's arc-shaped motion. This arc-shaped motion can cause the sterilization cart to collide with the fixed platform and misalign the sterilization cart during the lifting process. Utility Model Content
[0004] In order to solve the shortcomings of current technology, the utility model combines existing technology and, based on practical applications, provides a moving conveyor for a sterilization cart, which can solve the problems that the arc motion trajectory may cause the sterilization cart to collide with the fixed platform and the sterilization cart may be inaccurately positioned during the lifting process.
[0005] The technical solution of the utility model is as follows:
[0006] A traveling conveyor for a sterilization vehicle comprises a fixed platform, a lifting platform and a rocker arm. The rocker arm is driven by a cylinder. A slider mechanism is provided between the rocker arm and the lifting platform. The lifting direction of the lifting platform is vertical, and the movement direction of the slider mechanism is horizontal. A guide mechanism is provided between the lifting platform and the fixed platform for vertical guidance during the lifting process of the lifting platform.
[0007] Furthermore, the slider mechanism includes a slider and a guide rail, the guide rail is fixedly connected to the lifting platform, and the slider and the guide rail are slidably matched;
[0008] The rocker arm is connected to a spherical bearing, and the spherical bearing is connected to a slider.
[0009] Furthermore, the guide mechanism includes a guide column, a guide sleeve and a self-lubricating bushing. The guide sleeve is connected to the fixed platform, and the self-lubricating bushing is arranged in the guide sleeve. One end of the guide column is connected to the lifting platform, and the other end is slidably matched with the self-lubricating bushing.
[0010] Furthermore, a rocker arm is respectively provided at the four corners of the lifting platform, and a set of slider mechanisms and guide mechanisms are provided corresponding to each rocker arm.
[0011] Furthermore, two rocker arms adjacent to each other in the horizontal direction are connected by a pull rod, and two rocker arms adjacent to each other in the longitudinal direction are connected by a rotating shaft, wherein one of the rotating shafts is connected to the cylinder.
[0012] Beneficial effects of the utility model:
[0013] 1. This conveyor uses the principle of the rocker slider mechanism in mechanical design. A set of slider mechanisms is added at the connection between the lifting platform and the rocker arm, and a guide column is set between the lifting platform and the fixed platform for vertical guidance during the lifting process. In this way, when the cylinder drives the rocker arm to rotate, the slider mechanism converts the rotational motion into vertical linear motion through lateral displacement compensation, thereby solving the problem that the arc motion trajectory may cause the sterilization cart to collide with the fixed platform and the sterilization cart is inaccurately positioned during the lifting process.
[0014] 2. This conveyor can ensure the stable lifting movement of the lifting platform through the rational arrangement of multiple rocker arms, sliders and guide columns, and multiple rocker arms are driven by the same cylinder, with a compact and reasonable structural design.

[0022] The present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the contents of this invention, those skilled in the art may make various changes or modifications to the present invention, and that such equivalent forms also fall within the scope defined in this application.
[0023] This embodiment provides a moving conveyor for a sterilization vehicle, and its overall structure is as follows: Figure 1 as well as Figure 2 shown.
[0024] The traveling conveyor mainly comprises a fixed platform 1, a lifting platform 2, a rocker arm 3, a slider mechanism 4 and a guide mechanism 5. Among them, the rocker arm 3 is driven by a cylinder 6 to rotate, and the rocker arm 3 provides power to drive the lifting platform 2 to move up and down in the vertical direction.
[0025] In this embodiment, the slider mechanism 4 is provided between the rocker arm 3 and the lifting platform 2, and the movement direction of the slider mechanism 4 is horizontal. Figure 4 As shown, the slider mechanism 4 includes a slider 41 and a guide rail 42. The guide rail 42 is fixedly connected to the bottom of the lifting platform 2, and the slider 41 and the guide rail 42 are in sliding engagement. The rocker arm 3 is connected to the spherical bearing 8, and the spherical bearing 8 is connected to the slider 41. The rocker arm 3 is driven by the cylinder 6 to perform an arc motion. This arc motion can push the lifting platform 2 upward in the vertical direction. In the horizontal direction, it is compensated by the movement of the slider 41 along the guide rail 42, so that the lifting platform 2 only performs stable vertical linear motion, thereby solving the problem that the arc motion trajectory may cause the sterilization cart to collide with the fixed platform 1 and the sterilization cart to be inaccurately positioned during the lifting process.
[0026] Furthermore, in order to ensure that the lifting platform 2 only performs a single vertical linear motion, a guide mechanism 5 is provided between the lifting platform 2 and the fixed platform 1. Figure 5 As shown, the guide mechanism 5 includes a guide post 51, a guide sleeve 53, and a self-lubricating bushing 52. The guide sleeve 53 is connected to the fixed platform 1, and the self-lubricating bushing 52 is disposed within the guide sleeve 53. One end of the guide post 51 is connected to the bottom of the lifting platform 2, and the other end is slidably engaged with the self-lubricating bushing 52. The guide mechanism 5 can limit and guide the lifting platform 2, ensuring its vertical lifting motion driven by the rocker arm 3. Preferably, the guide mechanism 5 is located in a suitable position near the rocker arm 3.
[0027] In this embodiment, the lifting platform 2 is a rectangular frame structure. In order to ensure that the lifting platform 2 is evenly stressed and can operate flexibly and stably, Figure 3As shown, a rocker arm 3 is provided at each of the four corners of the lifting platform 2, and a slider mechanism 4 and a guide mechanism 5 are provided for each rocker arm 3. Two rocker arms 3 adjacent in the horizontal direction are connected by a pull rod 7, and two rocker arms 3 adjacent in the longitudinal direction are connected by a rotating shaft 9, one of which is connected to a cylinder 6 via a rocker arm. When the cylinder 6 performs telescopic movement, it can drive the rotating shaft 9 to rotate, and the rotating shaft 9 in turn drives the two rocker arms 3 connected at its ends to rotate. The two rocker arms 3, in turn, drive the other two rocker arms 3 to move synchronously via the pull rod 7, thereby achieving synchronous movement of the four rocker arms 3 at the four corners of the lifting platform 2, so that the four corners of the lifting platform 2 are simultaneously subjected to force and move up and down, ensuring stability during movement.
