Description

Novel hydraulic pin tooth car pusher roller

Technical Field

The utility model relates to a mining hydraulic pressure round pin tooth car pusher field, concretely relates to novel hydraulic pressure round pin tooth car pusher gyro wheel.

Background

In a transportation operation using a car, a car pusher is generally used to complete a position where a car is moved in order to complete a process such as loading, lifting, and unloading of the car. The following problems currently occur during operation: the running environment of the roller of the car pusher is severe due to more dust and larger moisture in the environment of the roller of the car pusher, and a shaft head of the roller of the existing dust car pusher is provided with a rolling bearing (as shown in figure 2), so that the sealing performance is poor, dust enters the shaft head of the roller of the car pusher to damage the rolling bearing, and after the rolling bearing is damaged, a set of roller assembly of the car pusher needs to be replaced every three months due to the fact that the rolling bearing and the roller rotate to wear the gap inside the roller, thereby not only influencing the lifting and transportation efficiency of a secondary well, but also seriously increasing the maintenance cost.

SUMMERY OF THE UTILITY MODEL

In order to solve the existing problem, the utility model provides a novel hydraulic pressure round pin tooth car pusher gyro wheel.

The utility model discloses a realize through following technical scheme:

the utility model provides a novel hydraulic pressure round pin tooth car pusher gyro wheel, includes the spindle nose at shallow spindle shaft both ends and the gyro wheel body of upper portion installation, and the outside of this gyro wheel body is provided with rather than the gyro wheel shell that matches, and the gyro wheel shell passes through end cover and gyro wheel body fixed connection, epaxial installation has slide bearing, slide bearing is including cup jointing the alloy endotheca of fixing on the spindle nose, the outside of alloy endotheca is fixed with the resin overcoat that excels in, open gyro wheel body inboard have a plurality ofly and the resin overcoat outside that excels in matches and swivelling joint's lubricated recess oil duct.

Preferably, the outside joint of spindle nose has restriction slide bearing's jump ring and the lock mother, the lock mother sets up the outside at the jump ring.

Preferably, the central part of the outer side of the roller shell is provided with a nozzle tip.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses a set up the slide bearing of constituteing by alloy endotheca, the resin overcoat that excels in the gyro wheel of mining shallow spindle to set up the lubricated recess oil duct that matches with the resin overcoat that excels in gyro wheel body inboard, can play fine lubricated effect and can strengthen the slide bearing wearability when slide bearing and gyro wheel body rotation each other like this, also reduced the noise when gyro wheel body moves simultaneously, the life of whole extension gyro wheel.

Drawings

Fig. 1 is a schematic structural diagram of the present invention;

FIG. 2 is a schematic diagram of a prior art structure of the present application;

in the figure: the trolley comprises a trolley crankshaft 1, a shaft head 2, a roller body 3, a rolling bearing 4, a roller shell 5, a nozzle tip 51, an end cover 6, a sliding bearing 7, an alloy inner sleeve 8, a high-strength resin outer sleeve 9, a lubricating groove oil duct 10, a clamp spring 11 and a lock nut 12.

Detailed Description

The invention will be described in further detail with reference to the following detailed description and accompanying drawings:

as shown in fig. 1 and 2, a novel hydraulic pin tooth car pusher roller comprises a shaft head 2 at two ends of a car pusher shaft 1 and a roller body 3 installed on the upper portion of the car pusher shaft, wherein a roller shell 5 matched with the roller body 3 is arranged on the outer side of the roller body 3, the roller shell 5 is fixedly connected with the roller body 3 through an end cover 6, a sliding bearing 7 is installed on the shaft head 2, the sliding bearing 7 comprises an alloy inner sleeve 8 fixed on the shaft head 2 in a sleeved mode, a high-strength resin outer sleeve 9 is fixed on the outer side of the alloy inner sleeve 8, and a plurality of lubricating groove oil passages 10 matched with the outer side of the high-strength resin outer sleeve 9 and connected with the roller body in a rotating mode are formed in the inner side of the roller body 3.

The outside joint of spindle nose 2 has the jump ring 11 and the lock mother 12 of restriction slide bearing 7, lock mother 12 sets up the outside at jump ring 11.

The roller housing 5 is provided with a nozzle 51 at the center of the outer side thereof.

The working principle is as follows: the sliding bearing 7 consisting of the alloy inner sleeve 8 and the high-strength resin outer sleeve 9 is arranged in the roller body 3 of the car pusher, the alloy inner sleeve 8 plays a role of fixing with a shaft head 2 of the car pusher shaft 1, the high-strength resin outer sleeve 9 has good wear resistance, the outer side of the high-strength resin outer sleeve 9 is in matched rotary connection with a plurality of lubricating groove oil channels 10 filled with lubricating grease in the inner side of the roller body 3, when the sliding bearing 7 and the roller body 3 rotate mutually, the good lubricating effect can be achieved, the wear resistance of the sliding bearing 7 can be enhanced, and meanwhile, the noise generated when the roller body 3 operates is also reduced;

lubricating grease is filled into the oil nozzle 51 of the roller shell 5, the cavity of the sliding bearing 7 of the roller body 3 is filled, and the sealing performance of the sliding bearing 7 is added, so that external dust can be well prevented from entering, the service life of a roller of the shaft 1 of the trolley is greatly prolonged, and the snap spring 11 and the locking nut 12 for limiting the sliding bearing 7 are arranged on the outer side of the shaft head 2, so that the roller shaft can be prevented from moving back and forth.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
