Description

Chain plate coupling mechanism for hoister and chain plate mechanism comprising same

Technical Field

The present patent application relates to automated manufacturing technologies in the advanced manufacturing industry, and more particularly to a link plate coupling mechanism for a hoist, which is applicable in scenarios including, but not limited to, the transportation of goods and raw materials into and out of an automated warehouse.

Background

As the expected capacity and automation of advanced manufacturing industry plants increases, more and more products, raw materials, etc. are managed and transported through automated warehouses of "smart factories". For example, in an automation line of an intelligent factory around the development of wire harness products, in order to fully utilize field resources, an automated warehouse often adopts a multi-level warehousing scheme, and therefore, a hoist is required to be used for box-type goods and raw materials to enter and exit the automated warehouse. For example, in one application example, in order to meet the requirement of on-site box-type goods and raw materials entering and exiting the automated warehouse, the goods need to be lifted to a height of 5 meters by using a lifting machine, the goods need to enter and exit on a conveying line with the height of 8 meters at most, and 200 boxes need to be lifted at most every hour.

The elevator itself is a commercially available product. Fig. 1A shows a perspective view of the connection between the link plate connecting knuckle 110 (at the end of the link plate connecting rod 140) and the hoist drive chain 120 in a commercially available hoist as a background to the present application. As shown in fig. 1A, this connection is a straight pin through connection, using a pin 130 shaped as shown in fig. 1B, passing through the through hole in the link plate's link knuckle 110 and the through hole in the drive chain 120 in the manner shown in the cross-sectional view of fig. 1C.

The diameter of the straight pin is limited by the size of the transmission chain, and is generally 6-8mm, and the diameter is thinner, so that the bearing capacity is lower, and is generally 20Kg-50Kg. If the case falls, blocks the case etc. the straight pin can be because of the crooked even fracture of atress. In addition, because the whole driving chain is loose, after the connecting joint piece of the chain plate is connected with the driving chain through the straight pin, a shearing stress exists on the straight pin. In normal use, during frequent conveying, the straight pins and the chain plates and the straight pins and the chain are repeatedly rubbed and frequently worn, and may need to be replaced in a short time (in an application example, the replacement is performed once in 1 month on average).

Detailed Description

In the following description, the present patent application is described with reference to various embodiments. One skilled in the relevant art will recognize, however, that the embodiments may be practiced without one or more of the specific details, or with other alternative and/or additional methods, materials, or components. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring aspects of embodiments of the present patent application. Similarly, for purposes of explanation, specific numbers, materials, and configurations are set forth in order to provide a thorough understanding of the embodiments of the present patent application. However, the present patent application may be practiced without specific details. Further, it should be understood that the embodiments shown in the figures are illustrative representations and are not necessarily drawn to scale.

Embodiments and variations of the present patent application are further described below with reference to the accompanying drawings.

Fig. 2A shows a partial schematic view of a hoist using a novel link joint connection structure according to an embodiment of the present application. FIG. 2B illustrates a backside configuration of the structure shown in FIG. 2A. Fig. 3 is a partial perspective view of the link plate connecting structure of the new type shown in fig. 2A. Fig. 4 shows a U-shaped connecting member in the novel link plate connecting structure shown in fig. 2A. Fig. 5A shows a configuration view of a U-shaped connector in an application example from a side, and fig. 5B shows a configuration view of the U-shaped connector shown in fig. 5A from an end face side, and the size unit in fig. 5A and 5B is millimeter (mm).

As shown in fig. 2A, the novel link plate connecting structure includes a U-shaped link member 230 having one end connected to the driving chain 220 and the other end connected to the link joint member 210 at the end of the link plate connecting rod 240.

One possible backside configuration of the structure shown in FIG. 2A is shown in FIG. 2B, although the scope of protection is not limited in this respect.

As seen in the partial perspective view of fig. 3, two chain connecting pins 250 are used to connect the right ends of the U-shaped links 230 to two adjacent links of the drive chain 220. The chain connecting pin 250 is long enough to pass through both links and one end of the U-shaped connecting member 230. After the chain connecting pins 250 extend through the two links and the U-shaped connecting member 230, a fixing end plate 270 may be used to fix the two chain connecting pins 250. As can also be seen in the partial perspective view of fig. 3, the left end of the U-shaped link 230 carries a link plate connecting pin 236. In a further embodiment, a bearing member 215 may be installed in the link joint member 210, and the link plate connecting pin 236 penetrates the bearing member 215 to be rotatable. The bearing member 215 may be a deep groove ball bearing.

Fig. 4 shows a perspective view of the U-shaped connector 230. It can be seen that the U-shaped connector 230 includes a base plate (web) 231, and first and second side walls 232, 233 at opposite ends of the base plate 231 and generally perpendicular to the base plate 231. Two pin holes 2321 are formed in the first side wall 232, and the distance between the two pin holes 2321 corresponds to the distance between two links of the driving chain, so that the two chain connecting pins 250 can pass through. The outer end of the second side wall 232 is formed with a link plate attachment pin 236 for passing through the attachment knuckle 210. A threaded rod 2361 may be formed at the end of the link plate connecting pin 236 for receiving a retaining nut.

In a variation, the first and second sidewalls 232 and 233 may extend beyond both sides of the base plate 231, i.e., the base plate (connecting plate) is connected at the middle of the first and second sidewalls 232 and 233.

In a variation, the number of pin holes in the first side wall 232 may be three or more.

In combination with the above embodiments, it can be understood that the advantageous effects can be obtained at the point of improvement of the present patent application. First, one U-shaped link 230 mates with two links of the drive chain, thus increasing the size of the link to link joint by a factor of 2 and the strength by a factor of 4 compared to the implementation of FIGS. 1A-1C. Secondly, through increase the bearing spare at the connecting piece with the link joint, can make the link joint operation more smooth and easy, reduce the junction joint wear. In the application example of fig. 5A-5B, the joint component life is extended by a factor of 15-20. Thirdly, the connecting strength of the connecting piece and the driving chain is increased by 2 times by connecting 2 straight pins at the connecting part of the connecting piece and the driving chain. Finally, the U-shaped connecting piece 2 is fixed, so that the chain plate is more stable in the operation process, and the problems of case clamping and the like of the elevator are solved.

Having thus described the basic concept, it will be apparent to those skilled in the art that the foregoing disclosure is by way of example only, and is not intended to limit the present patent application. Various modifications, improvements and adaptations to the present application may occur to those skilled in the art, although not explicitly described herein. Such alterations, improvements, and modifications are intended to be suggested in this application and are intended to be within the spirit and scope of the embodiments of the application.
