Telescopic arm supporting roller of iron mixing car capping robot

Abstract

The invention discloses a supporting roller for a telescopic arm of a capping robot of a torpedo car. The supporting roller is designed and installed at the bottom of a fixed arm of the telescopic arm of the capping robot, and sliding friction between a movable arm and the fixed arm in the original design can be converted into rolling friction. Therefore, friction force between the movable arm and the fixed arm can be greatly reduced, the abrasion condition of the copper sliding block is improved, and the service life of the copper sliding block is prolonged. And therefore, the replacement cost of the copper sliding block is reduced, the maintenance cost of the capping robot is reduced, and the labor intensity of maintenance personnel is relieved. Meanwhile, as the friction force is reduced, the energy consumption is reduced, the electric power resource is greatly saved, and the device is more environment-friendly. In addition, the supporting roller is compact in internal structure and light in weight, so that workers can maintain the supporting roller conveniently.

Description

Technical Field

[0001] The invention belongs to the field of iron and steel metallurgical machinery and production automation, and more specifically, relates to a telescopic arm support roller of a mixing iron car capping robot. Background Art

[0002] As the international community pays more attention to the ecological environment, countries around the world have taken measures to promote carbon emission reduction.

[0003] In recent years, most large steel mills in China have used iron-mixing cars to transport molten iron. In the process of transporting molten iron, iron-mixing cars produce a lot of smoke and dust due to open transportation, which is harmful to the natural environment. In addition, open transportation also reduces the temperature of molten iron, causing energy loss. Because iron-mixing cars carry high-temperature molten iron, there are also potential hazards such as slagging at the furnace mouth and tipping. In order to solve the above problems, Baowu Heavy Industries Co., Ltd. successfully developed an iron-mixing car capping robot, but the friction is too large during use, which easily causes wear of the telescopic arm, high maintenance costs, and high energy consumption.

[0004] The present invention provides a telescopic arm support roller of a hybrid car capping robot to solve the above-mentioned technical problems, and specifically adopts the following technical solutions:

[0005] A telescopic arm support roller of a hybrid car capping robot comprises: a roller sleeve and a transverse axis; the transverse axis is arranged through the roller sleeve; both ends of the transverse axis extend out of the roller sleeve; both ends of the roller sleeve are provided with end covers for closing the roller sleeve; threaded holes are formed in the circumference of both ends of the roller sleeve; the end covers are screwed into the threaded holes through the holes formed by the end covers to be fixed to the ends of the roller sleeve; bearings are installed between the roller sleeve and the transverse axis at both left and right ends of the transverse axis, which are divided into left bearings and right bearings; the left end and the right end of the transverse axis are respectively formed with a left shaft shoulder and a right shaft shoulder; the right side of the left bearing abuts against the left shaft shoulder, and the left side of the left bearing is provided with A left retaining ring is provided for fixing the left bearing; the left retaining ring is clamped on the outer periphery of the left end of the horizontal shaft; the inner side of the end cover provided on the left side of the roller sleeve abuts against the outer periphery of the left bearing; the left side of the right bearing abuts against the right shaft shoulder, and a right retaining ring for fixing the right bearing is provided on the right side of the right bearing; the right retaining ring is clamped on the outer periphery of the right end of the horizontal shaft; a grease cavity for storing grease is provided between the roller sleeve and the horizontal shaft; an oil filling pipeline is provided inside the horizontal shaft; a threaded cavity for installing an oil cup is provided at the end of the horizontal shaft; the two ends of the oil filling pipeline are respectively connected to the oil cup and the grease cavity in the threaded cavity.

[0022] like Figure 1As shown, a telescopic arm support roller 10 of a hybrid car covering robot of the present application is provided, comprising: a roller sleeve 11 and a transverse axis 12. The transverse axis 12 is arranged to penetrate inside the roller sleeve 11. Both ends of the transverse axis 12 extend out of the roller sleeve 11. End covers 13 are provided at both ends of the roller sleeve 11, which are used to close the end covers 13 of the roller sleeve 11. Threaded holes are formed in the circumference of both ends of the roller sleeve 11. The end cover 13 passes through the hole formed by the end cover 13 through a screw 131, and then is screwed into the threaded hole, so that the end cover 13 is fixed to the end of the roller sleeve 11. A bearing is installed between the roller sleeve 11 and the transverse axis 12, and the bearing is divided into a left bearing 14 and a right bearing 15 at the left and right ends of the transverse axis 12. A left shoulder 121 and a right shoulder 122 are formed at the left end and the right end of the transverse axis 12, respectively. The right side of the left bearing 14 abuts against the left shoulder 121. A left retaining ring 16 is provided on the left side of the left bearing 14, and the left retaining ring 16 is used to fix the left bearing 14. The left retaining ring 16 is clamped on the outer periphery of the left end of the horizontal shaft 12. The inner side of the end cover 13 provided on the left side of the roller sleeve 11 abuts against the outer periphery of the left bearing 14. The left side of the right bearing 15 abuts against the right shoulder 122. A right retaining ring 17 is provided on the right side of the right bearing 15, and the right retaining ring 17 is used to fix the right bearing 15. The right retaining ring 17 is clamped on the outer periphery of the right end of the horizontal shaft 12. A grease chamber 18 is provided between the roller sleeve 11 and the horizontal shaft 12 for storing grease. An oil filling pipeline 19 is provided inside the horizontal shaft 12. A threaded cavity is provided at the end of the horizontal shaft 12, and the threaded cavity is used to install an oil cup 20. The two ends of the oil filling pipeline 19 are respectively connected to the oil cup 20 and the grease chamber 18 in the threaded cavity. When filling grease, the oil filling pipeline 19 is connected to the oil cup 20, and the grease is filled into the grease chamber 18 through the oil filling pipeline 19, thereby achieving the purpose of bearing lubrication.

[0023] As a further solution, a 1 mm gap is formed between the right side of the right bearing 15 and the end cover 13 provided on the right side of the roller sleeve 11. A 1 mm gap is formed between the left side of the right bearing 15 and the roller sleeve 11. This is to ensure that there is enough space between the right bearing 15, the end cover 13 and the roller sleeve 11 when the support roller is in a high temperature state.

[0024] As a further solution, a sealing ring 21 for preventing grease leakage is installed between the end cover 13 and the transverse shaft 12. The sealing ring 21 plays a role in protecting the support roller from grease erosion.

[0025] As a further solution, a bolt is fixed on one side of the oil cup 20 close to the horizontal axis 12. The oil cup 20 is screwed to the threaded cavity by the bolt. In this way, the oil cup 20 can be connected to the oil filling pipeline 19, which is convenient for filling grease.

[0026] As a further solution, the bearing is a spherical roller bearing. The spherical roller bearing can bear radial load and axial load at the same time, increase the bearing capacity of the support roller, and better meet the actual working conditions of the telescopic arm.

[0027] As a further solution, the roller sleeve 11 is made of medium carbon steel or alloy steel. The horizontal shaft 12 is made of medium carbon steel or alloy steel. Such materials have been quenched and tempered, have good mechanical properties and processing properties, and better meet the needs of telescopic arm operation.

[0028] As a further solution, the end cover 13 is made of low carbon steel.

[0029] The above shows and describes the basic principles, main features and advantages of the present invention.
