Description

High-flange composite guide roller, lifting chain and transmission structure adopting same

Technical Field

The utility model belongs to the technical field of stereo garage and specifically relates to gyro wheel and adopt promotion chain, the transmission structure of this gyro wheel.

Background

The transmission mode that the perpendicular circulation stereo garage that provides on the market at present adopted is chain and dials formula secondary drive system. As shown in fig. 14-16, the two lifting chains 70 of the vertical circulation stereo garage are respectively installed at the left and right ends of the frame body 90; the two lifting chains 70 are respectively connected with a fork wheel 80; the fork 80 is mounted on a drive shaft 81; the drive wheel 82 on the drive shaft 81 is connected to a reduction motor 83 via a drive chain 84. A plurality of vehicle carrying chain plates 17 are respectively arranged on the two lifting chains 70, a vehicle carrying hanger mounting cross rod 18 is arranged between the vehicle carrying chain plates 17 at the same height, and a vehicle carrying hanger 19 is arranged on the vehicle carrying hanger mounting cross rod 18. In the power transmission system in the prior art, if a large-diameter shifting fork wheel is adopted, the shifting fork wheel is easy to deform when bearing large stress due to too large gear ratio, so that the shifting fork wheel can only be a small shifting fork wheel with 3-4 teeth, and the diameter of the shifting fork wheel 80 is generally about 700 mm. Due to the fact that the number of the shifting forks is small, the shifting fork wheel 80 and the lifting chain 70 are not tightly combined, stress concentration is generated, the shifting fork wheel is abraded greatly, the existing vertical circulation stereo garage is poor in transmission stability and not stable in operation, and once the chain or the shifting fork wheel are not tightly combined or broken, the automobile carrying hanger in the vertical circulation stereo garage is directly caused to accidentally fall off, and great potential safety hazards exist.

Two types of circulation systems are commonly used in the market. A top and bottom all adopt circulation big sprocket, promptly "double sprocket" system, adopt this "double sprocket" circulation system, from the analysis of principle, can't solve the "polygon effect" of big pitch chain more than 400mm, so there are the phenomenon of "elasticity when loose" and "chain jump" all the time in the operation process. Want to solve this kind of problem, only increase substantially the chain rate of tension, can produce certain effect, but the consequence of doing so has increased frictional resistance undoubtedly, and power consumption also follows the promotion, and the needs frequently advance, has also brought the increase of equipment maintenance cost. No matter the lifting chain and the shifting fork wheel are arranged at the upper end or the bottom in the meshing process, a couple F can be generated on the lifting chain under the action of the self-weight load and the rated load Q of the vehicle carrying tray connected with the triangular plate of the lifting chain. Under the action of the couple, the chain plate and the guide wheel entering the meshing neutral gear area can rotate to separate from the normal motion track, so that the result is that a light person jumps, the heavy person blocks, and a heavy person blocks, and the equipment cannot be normally used. Secondly, a circulating large chain wheel is not adopted, the top and the bottom of the circulating large chain wheel are both semicircular arc guide rails and are in butt joint with a vertical guide rail of a lifting chain, the circulating system can effectively solve the problems of 'tightness in time' and 'chain jumping' of the lifting chain in the circulating process by simulating and designing the running track of the guide rail, but the power input of the circulating system still needs to be matched with a 'shifting fork wheel', the technical defects of the shifting fork wheel cannot be solved, and the circulating system is not an ideal system scheme. The occurrence of the phenomenon of 'chain jumping' or 'jamming' of a circulating system lifting chain can cause the resistance, noise increase, high energy consumption and even 'stuffy car' of the system operation, which is a long-standing potential safety hazard influencing the normal operation of the whole machine.

The nylon layer 3 is an oil-containing nylon layer. Noise generated during the operation of the lifting chain 70 of the stereo garage mainly comes from the friction between the steel guide wheel and the guide rail in the circulation process of the lifting chain. Under the condition that the structure of the main body frame is reasonably designed and manufactured, the main means of reducing noise is an innovative operation technical principle, and the friction force is reduced to the maximum extent. The traditional rigid operation principle is overturned by adopting the high-flange composite guide roller. The engineering plastic is a high-strength polymer material, the friction coefficient is small, and the flexible steel is realized between friction pairs. The installation running test shows that the overall noise of the equipment is greatly reduced and is not more than 50Db, no lubrication is needed, the environment is protected, no pollution is caused, and the maintenance cost is low.

The diameter of the roller body 1 is 60-100mm, the thickness of the nylon layer 3 is 20-60mm, and the diameter of the flange 2 is 10-30 mm.

The roller body 1 and the two flanges 2 are integrally cast.

Example 2. As shown in fig. 6, the present embodiment is different from embodiment 1 in that: a plurality of through holes 4 used for pouring nylon layers 3 are arranged on each flange 2 along the central axis direction of the roller body 1. The diameters of the through holes 4 are the same, and the distances from the centroids to the central axis of the wheel body are the same.

The roller body 1 is internally provided with a wheel shaft mounting hole 5, and the central axis of the wheel shaft mounting hole 5 is superposed with the central axis of the roller body 1.

Example 3. As shown in fig. 2 and 4-5, a lifting chain of a vertical circulation stereo garage is characterized in that: the lifting chain is an annular structure formed by connecting a plurality of chain links end to end in sequence, and two adjacent chain links are hinged together through a wheel shaft 6; the radial peripheral surface of the wheel shaft 6 is sleeved with a high-flange composite guide roller; each chain link comprises two chain plates 7 which are arranged in parallel, the same ends of the two chain plates 7 are hinged with a wheel axle 6 and are vertical to the axle wire of the wheel axle 6, and the high-flange composite guide roller is positioned between the two chain plates 7 of each chain link on the wheel axle 6.

A rolling body 14 is sleeved between the roller body 1 and the wheel shaft 6, and the rolling body 14 is a ball bearing.

The length of the chain link plate 7 is 40-50 cm.

Example 4. As shown in fig. 3, the present embodiment is different from embodiment 3 in that: a wear-resistant sleeve 15 or a rolling body 14 is sleeved between the roller body 1 and the wheel shaft 6, and the rolling body 14 is a ball bearing or a roller bearing or a needle bearing.

Example 5. As shown in fig. 8-10, in a transmission structure of a vertical circulation stereo garage, the left and right ends of a frame body of the vertical circulation stereo garage are respectively and vertically provided with lifting chains shown in embodiment 3, and each lifting chain is respectively connected with a large circulation transmission chain wheel 16; the large endless transmission sprocket 16 is provided at its radially outer peripheral surface with a plurality of chain driving grooves 20, and the roller bodies 1 of the rollers for lifting the chain can be engaged in the chain driving grooves 20 when the large endless transmission sprocket 16 is rotated. The design of the circular transmission large chain wheel 16 is improved by referring to the standard GB8350-2003 transport chain, accessories and chain wheels, because products applied to the market are not improved according to different use conditions, and the problem of poor meshing exists. In the international standard for transmission short-pitch precision roller chains and sprockets in ISO 606-1994, no specific sprocket tooth form is specified, but only the maximum tooth groove form and the minimum tooth groove form of the sprocket are specified. However, in designing an endless large sprocket, in addition to ensuring that the chain is smoothly engaged into and out of the sprocket and having a good machining process, the inventors have considered the following principles: the sprocket teeth must be able to absorb and transmit chain tension, and the sprocket is further required to be able to achieve smooth and continuous operation; the sprocket teeth must reasonably accommodate chain elongation and wear at the face and root circles of the sprocket teeth; the sprocket teeth must be compatible with the operating conditions of use. Such as the running speed of the chain, whether foreign objects fall into the meshing part of the chain and the chain wheel, etc. The circular large chain wheel is optimally designed, and key performance parameters such as tooth space center separation amount, meshing pressure angle, chain wheel tooth surface arc radius, root circle diameter and the like are optimized through multiple installation experiments. The full-length contact of the meshing surface between the lifting chain guide wheel and the lifting chain guide wheel is realized, and high meshing transmission performance is obtained. The tooth surface of the gear has high abrasion resistance and high extrusion strength by strictly controlling the heat treatment process, and the gear replaces a four-tooth shifting fork wheel commonly adopted in the existing market, so that the chain wheel works more stably and reliably, and the service efficiency of equipment is further improved.

A plurality of vehicle-carrying chain plates 17 are respectively arranged on the two lifting chains, a vehicle-carrying hanger mounting cross rod 18 is arranged between the vehicle-carrying chain plates 17 at the same height, and a vehicle-carrying hanger 19 is arranged on the vehicle-carrying hanger mounting cross rod 18; the radial peripheral surface of the roller body 1 of each roller is meshed with the chain driving groove 20 of the large circulating transmission chain wheel 16; a plurality of guide plates 21 are vertically and inwardly arranged in the lifting chain on the frame body of the vertical circulating stereo garage, and when the lifting chain rotates, the radial peripheral surface of the part of the thicker flange of the two flanges of each roller can be contacted with the guide plates 21. And a computer digital collaborative design technology is adopted, and the accurate simulation of the lifting of the large chain running track is realized through iterative calculation. For example, when the center distance of the circular track of the large lifting chain is Ayh =1472.41mm, and the chain deflects 18 ° to a single side (left or right) at the lowest triangle, the lifting chain is tensioned, and then the maximum slack amount in the chain running process is: Δ max = Kmax-Kmin =455.00-454.74=0.26mm, which is completely negligible compared to the order of magnitude of the total length of the entire chain, and the results of the tests are also well documented: the phenomena of 'polygon effect' and 'chain jumping' of the lifting chain do not occur any more, and the problems are thoroughly solved. In order to ensure that the high-strength guide plate can work reliably, the high-strength guide plate has enough extrusion strength, hardness and wear resistance, so that the guide plate 21 is made of a wear-resisting plate with excellent comprehensive performance. The yield strength is more than 900 MPa, and the Brinell hardness is 570-600.

The thickness of the flange of the end, close to the vehicle carrying hanger 19 end of the stereo garage, of the two flanges of each roller is larger than that of the end, far away from the stereo garage, of the vehicle carrying hanger 19 end of each roller; two guide plates 21 are respectively arranged at the front end and the rear end of the large circulating transmission chain wheel 16 close to the vehicle carrying hanger 19 side of the stereo garage; the front side surface of a guide plate 21 positioned at the front end of the circulating transmission large chain wheel 16 close to the vehicle-carrying hanger 19 side of the stereo garage is contacted with the radial outer peripheral surface of the thicker flange of the two flanges of the roller; the rear side surface of the guide plate 21 positioned at the rear end of the circulating transmission large chain wheel 16 close to the vehicle-carrying hanger 19 side of the stereo garage is contacted with the radial outer peripheral surface of the part of the thicker flange in the two flanges of the roller.
