Description

TECHNICAL FIELD

[0001] The application is a high-speed elevator and multi-stage buffer protection device, which belongs to the technical field of four-way shuttle vehicle transportation and bearing. BACKGROUND

[0002] When the existing four-way shuttle vehicle cooperates with the high-speed elevator to perform three-dimensional motion, the shortcomings of insufficient efficient buffer protection mainly manifest in that the car is easily impacted and settled, the risk of rigid collision of the equipment is high, the service life of the buffer assembly is short, and the stability of the goods is poor. For example, the downward impact force generated when the shuttle vehicle enters the elevator car will cause the car to settle greatly, accelerating the wear of the chain, and the high-speed start-stop or docking of the elevator with the goods shelf is easy to cause rigid collision of the shuttle vehicle with the car and the goods shelf, and the goods are easy to slide or overturn due to insufficient buffer. These shortcomings are caused by the contradiction between the high inertia of the high-speed elevator operation and the passivity of the buffer system. When the elevator is raised at high speed, the inertia of the car and the load is large, and the existing buffer is mainly a passive structure triggered after impact. In addition, the position deviation of the shuttle vehicle and the elevator during docking will amplify the impact effect, and in addition, network delay or sensor response lag also cause the buffer action to fail to intervene in advance. The conventional methods include: installing anti-collision rubber blocks and other elastic components on the upper and lower ends of the car, improving the strength of the chain and other transmission parts, adding a hovering mechanism to limit the settlement of the car, and setting a spring type buffer assembly on the shuttle vehicle. However, such methods have obvious disadvantages: passive buffers such as rubber blocks can only alleviate the end impact and cannot reduce the impact energy, and are prone to aging and failure. Therefore, there is an urgent need for a high-speed elevator and multi-stage buffer protection device to solve the above problems. SUMMARY

The inner sides of the upper and lower sides of the upper movable support arm 32 and the lower movable support arm 35 are each provided with a group of inner connecting bearings for connecting the damping rotary shafts.

[0022] The inclination angles of the ipsilateral upper movable support arm 32 and the ipsilateral lower movable support arm 35 are symmetrically matched. The upper end of the upper movable support arm 32 is movably connected to the movable support joint by a damping rotary shaft. The lower end of the lower movable support arm 35 is provided with a group of lower support columns 37 for supporting the lower end. The upper end of the lower support column 37 is provided with a convex lower movable support joint. The upper end of the lower movable support joint is movably connected to the lower end of the lower movable support arm 35 by a damping rotary shaft.

The lower end of the right outer fixed head 9e is provided with a group of side buffer support rods two for buffering the lateral pressure of the lower buffer column 39. The side buffer support rod one 9f and the side buffer support rod two are symmetrically arranged, and have the same structure.

[0024] The side buffer support rod one 9f and the side buffer support rod two are both air damping support rods. The side buffer support rod one 9f and the side buffer support rod two are respectively provided with a group of fixing seats 9h at the lower ends thereof for supporting and fixing the same. The fixing seats 9h are provided with a group of inner mounting cavities at the middle positions of the upper ends thereof for positioning and embedding the bottom portions of the side buffer support rod one 9f and the side buffer support rod two. The two groups of fixing seats 9h are connected and fixed with the left and right sides of the bottom portion of the guide shell 9b. The upper stress column 9a is divided into three sections, i.e., an upper section, a middle section and a lower section. The upper section, the middle section and the lower section are integrated structures. The upper section is a solid column.

[0025] The lower end of the upper compression spring 9i is provided with a group of partition seats 9j for supporting the lower end thereof. The partition seats 9j are located at the connection positions between the middle sections and the lower sections. The upper end of the lower section is a damping inner core which is the same as the middle section. The lower end of the lower section is an inner head for fixedly connecting with the inner support tower top 9l. The outer side of the lower section is provided with a group of lower compression springs 9k for reducing the pressure of the second stage of the buffer. The lower end of the lower compression spring 9k is provided with a group of inner support tower tops 9l for supporting the bottom portions thereof.

The height of the upper loading plate is adjusted through the upper support lifting cylinder 201. The motor one 29 drives the lateral guide belt 26 through the inner gear shaft rod 28. The shuttle vehicle is accurately positioned through the cooperation of the limiting clamping strips. Then, the motor two 204 is started to drive the lifting chain 23 through the lower gear shaft rod 202 to retract and release. The loading rack 5 is pulled along the inner fitting rail through the upper fixed anchor head 27. The lateral guide wheel 6 ensures stable operation. The limiting plate 24 limits the amplitude of chain retraction and release. When the loading rack 5 is lowered to approach the bottom portion, the upper support top 31 of the buffer protection component 3 is triggered first. The upper and lower movable support arms 35 are rotated through the damping rotating shaft. The side buffer column 303 and the buffer spring 36 complete the first stage of buffering. If the impact force is continuously transmitted to the lower stage of the buffer column 39, the upper stress column 9a is first stressed. The middle extension rod is retracted. The upper compression spring 9i is compressed. The middle damping inner core reduces the release rate of the pressure. The partition seat 9j supports the upper compression spring 9i and transmits the pressure to the lower portion. The lower compression spring 9k is compressed. The lower damping inner core further buffers. At the same time, the side buffer support rod one 9f and the side buffer support rod two dampen and buffer the roll pressure, avoiding the roll of the outer fixed shell 9d; the pressure is finally transmitted to the inner support tower top 9l, the inner reverse buffer damping column 9m releases the pressure again through the elastic tension, and the support bottom column 9n keeps the whole stable, realizing multi-stage progressive buffering.
