Description

Technical Field

[0001] The invention belongs to the field of ultrafine pulverizer equipment, relates to the suspension of a pulverization bin, and in particular to a telescopic safety device of the ultrafine pulverizer. Background Art

[0002] For example, the application document CN202022798204.8 discloses a vibrating ultrafine pulverizer, in which a pulverizing drum is suspended by a hanging assembly. A motor drives the pulverizing drum to vibrate, causing the crushing rollers inside the drum to collide with each other and crush the material. However, due to metal fatigue, overstretching, and other factors, the spring in the hanging assembly is at risk of breaking, and the elastic coefficient k decreases. Therefore, a device is needed to protect the spring from overstretching and breaking. Summary of the Invention

[0003] In view of the above problems, the present invention provides a telescopic safety device for preventing a spring from being overstretched.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a telescopic safety device of an ultrafine pulverizer, comprising a vibration isolation spring, each end of the vibration isolation spring is connected to a spring plug, a countersunk hole is provided in the middle of the spring plug, a telescopic limiting mechanism is provided between the two spring plugs, the telescopic limiting mechanism comprises a safety rope, each end of the safety rope is provided with a rope loop, the rope loop is connected to a pulley, the rope pulley is connected to a suspension rope, and the suspension rope passes through the countersunk hole.

[0005] Preferably, the countersunk hole includes a large hole and a small hole that are connected to each other, and the rope pulley is embedded in the large hole.

[0006] Preferably, the number of the safety ropes is 2, which are distributed on both sides of the suspension rope on the rope pulley.

[0007] Compared with the prior art, the advantages and positive effects of the present invention are: The present invention provides a telescopic limit mechanism in the spring. Before the spring reaches an overstretched length, the safety rope in the telescopic limit mechanism is tensioned and withstands the tension from the crushing cylinder. Therefore, the present invention can protect the spring from overstretching and extend the service life of the spring.

[0008] The invention has a simple structure, is easy to manufacture, and is suitable for popularization and use. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following is a brief introduction to the drawings required for use in the description of the embodiments. Obviously, the drawings described below are some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative labor.

[0012] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0013] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0014] like Figure 1 、 Figure 2 As shown, a telescopic safety device of an ultrafine pulverizer includes a vibration isolation spring 1, with spring plugs 2 connected to both ends of the vibration isolation spring 1, a countersunk hole 21 provided in the middle of the spring plug 2, a telescopic limiting mechanism provided between the two spring plugs 2, and the telescopic limiting mechanism including a safety rope 3, with a rope loop 31 provided at both ends of the safety rope 3, the rope loop 31 is connected to a pulley 4, the pulley 4 is connected to a suspension rope 5, the suspension rope 5 passes through the countersunk hole 21, the suspension rope 5 extending upward is connected to the hanger, and the suspension rope 5 extending downward is connected to the pulverizing cylinder, thereby suspending the pulverizing cylinder.

[0015] Specifically, when the crushing cylinder is stationary, the safety rope 3 is in a relaxed state. When the crushing cylinder shakes, the vibration isolation spring 1 is stretched, and the distance between the two pulleys 4 increases, causing the safety rope 3 to tend to be tightened. When the safety rope 3 is tightened, the safety rope 3 bears the tension from the crushing cylinder, which reduces the tension on the vibration isolation spring 1, and the vibration isolation spring 1 is no longer stretched, thereby avoiding excessive stretching of the vibration isolation spring 1.

[0016] Furthermore, the countersunk hole 21 includes a large hole 211 and a small hole that are connected to each other, and the rope wheel 4 is embedded in the large hole 211.

[0017] Furthermore, the number of the safety ropes 3 is two, which are distributed on both sides of the suspension rope 5 on the rope pulley 4.

[0018] The above description is merely a preferred embodiment of the present invention and does not constitute any other form of limitation to the present invention. Any person skilled in the art may utilize the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes for application in other fields. However, any simple modification, equivalent change, and modification of the above embodiments made in accordance with the technical essence of the present invention without departing from the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
