Description

TECHNICAL FIELD

[0001] The present application relates to the technical fields of mechanical manufacturing and material pushing device, in particular to a columnar body pushing device and a method for using the same. BACKGROUND

[0002] At present, with the gradual increase of material load weight, length and filling height, the manual filling has reached its limit, and the filling mechanism is an inevitable development direction. Moreover, some working conditions have strict requirements for filling installation space, so a more compact pushing mechanism is needed.

[0003] In the prior art, the pushing mechanism has a multi-stage telescopic hydraulic cylinder, a multi-stage telescopic electric push rod and a separate rigid chain device. The multi-stage telescopic hydraulic cylinder transmission needs a hydraulic pump station, which has a bulky structure, a large installation volume, and a high manufacturing precision and a high price of the hydraulic element. Moreover, the hydraulic element is sensitive to pollution, easy to block and wear, the hydraulic pump has a large noise, the hydraulic oil is easy to leak, and the energy loss is large in the working process, the system efficiency is low, the oil temperature is sensitive, and the temperature change can cause the change of the viscosity of the hydraulic oil. In addition, it is not easy to find the cause of the fault. The multi-stage telescopic electric push rod has low speed, a large installation structure, easy wear, a malfunction of the travel switch, unreliable overload protection, high cost and immature technology. Chain transmission is an important part of mechanical systems, and is widely used in industrial, mechanical manufacturing, agricultural machinery, hoisting and transportation fields due to its characteristics of no sliding, compact structure and high transmission efficiency. With the continuous development of science and technology, people have higher and higher requirements for chains, and the functions to be realized are also more and more, so various new chains have emerged. For the load distance straight line motion, the ordinary chain and the rigid rope have too single function, and can only provide pulling force. To solve this problem, the rigid chain is applied. The rigid chain is a special structure chain that can realize straight line pushing and pulling. It is flexible in one direction and can be bent and folded like an ordinary chain. It is rigid in the other direction and can provide pushing force like a rigid rod, but it must have a guide device. At present, the rigid chain has been widely used in various industries, such as industry, agricultural machinery and stage lifting, compared with the multi-stage telescopic hydraulic cylinder, the multi-stage telescopic electric push rod and the mechanical hand, the chain transmission structure is more compact, the transmission distance is long, and the positioning accuracy and stability are high, so the size of the whole filling system can be effectively reduced.

[0004] Based on the above, there are at least one technical problems:

[0005] The multi-stage telescopic hydraulic cylinder transmission needs a hydraulic pump station, which has a bulky structure, a large installation volume, and is sensitive to pollution, easy to be blocked and worn, has high manufacturing precision and a high price, and has a large noise. In addition, the hydraulic oil is easy to leak, and if not properly handled, the leakage not only pollutes the site, but also can cause fire and explosion accidents when there is a fire source nearby. Moreover, the system has a large energy loss, a low efficiency, and is sensitive to oil temperature, and is not suitable for working at a very high or very low temperature, because the viscosity of the hydraulic oil will change due to temperature change. In addition, it is difficult to find the cause of the fault.

[0006] The multi-stage telescopic electric push rod has the disadvantages of low speed, large installation structure, easy wear, easy failure of the travel switch, unreliable overload protection, high cost, and immature technology.

[0007] The common chain and rigid rope have a single function and can only provide a pulling force. SUMMARY
