Description

Ground ox roller dismounting tool Technical Field The utility model relates to a floor-cattle maintenance tool, in particular to a floor-cattle roller dismounting tool. Background The utility model provides a ground ox, also known as hydraulic carrier, is a heavy object conveyer that commonly uses, has hydraulic means between chassis and the gyro wheel, can be convenient push into the car under the packing box base, then rise the chassis with hydraulic pressure, hold up the goods, alright drag the goods and remove, after reaching the destination, land the chassis with hydraulic pressure, the goods falls to the ground along with it also, the carrier that takes out that can be convenient. The ground ox roller is installed on the crane through the shaft, and the roller is generally made of a material with good wear resistance, but the roller still can be worn to a certain extent after long-time use, and the roller needs to be replaced after the roller is worn. When the ground ox roller is replaced, a maintainer needs to hold the punch by one hand, the end part of the punch is aligned with the end part of the roller shaft, then the other hand holds the hammer to strike the punch, and the roller shaft of the roller is axially detached by the impact force of the punch, so that the roller is detached. In the existing mode that a maintainer holds the punch to disassemble the cow roller, the punch is easy to deviate from the end part of the wheel shaft, and a certain danger exists. Disclosure of utility model The utility model aims to provide a ground ox roller dismounting tool which solves the problem that the existing mode of dismounting the ground ox roller by holding a punch is high in risk. The ground ox roller dismounting tool comprises a first sleeve, a second sleeve, a connecting arm, an adjusting sleeve and a punch, wherein the first sleeve, the second sleeve and the adjusting sleeve are coaxially arranged, the first sleeve and the second sleeve are connected with each other through the connecting arm positioned at one side, the adjusting sleeve penetrates through the second sleeve, the extending length of the adjusting sleeve can be adjusted in the second sleeve by the adjusting sleeve, the punch is connected in the adjusting sleeve in a penetrating mode, and the punch is connected with the adjusting sleeve in a sliding mode. As a further improvement of the local cow roller dismounting tool, the inner wall of the second sleeve is provided with an inner thread, the outer wall of the adjusting sleeve is provided with an outer thread, and the second sleeve is connected with the adjusting sleeve through threads. As a further improvement of the cow roller dismounting tool, a rotary operation part is arranged at the outer end part of the adjusting sleeve and is used for rotating the adjusting sleeve. As a further improvement of the local cow roller dismounting tool, the connecting arm is arc-shaped, U-shaped or V-shaped. As a further improvement of the bull roller removal tool of the present utility model, the length of the adjustment sleeve is greater than the length of the second sleeve. As a further improvement of the local cow roller dismounting tool, the diameter of the inner wall of the first sleeve is larger than the diameter of the roller shaft, and the diameter of the punch is smaller than the diameter of the roller shaft. As a further improvement of the dismounting tool for the local cow roller, the punch is of a cylindrical structure. As a further improvement of the bovine roller removal tool of the present utility model, the spacing between the first sleeve and the second sleeve is greater than the length of the roller axle. As a further improvement of the cow roller dismounting tool, a conical guide part is arranged at the inner end part of the adjusting sleeve. The utility model is used for replacing the hand fixing punch of an operator when the ground ox roller is dismounted, the utility model is fixed at the two ends of the wheel shaft of the ground ox roller through the adjusting sleeve and the first sleeve, the second sleeve and the adjusting sleeve are coaxial with the wheel shaft, and the punch is coaxial with the wheel shaft after penetrating into the adjusting sleeve. The punch is guided by the adjusting sleeve, so that the punch can move along the axial direction and cannot shift along the radial direction. The outer end of the punch is knocked by external force, so that the punch contacts with the end part of the wheel shaft and gradually ejects the wheel shaft into the first sleeve in the axial direction, the wheel shaft is completely ejected, the ground ox roller is detached, a person does not need to hold the punch in the whole process, and the safety of the ground ox roller in the detaching process is improved.
