An electric control button controls an external oil source to enter the pure liquid type machine core, so that a piston is controlled to reciprocate to strike a punch, and further a detached part is struck; the taper sleeve device guides the punch head to realize accurate positioning and dismounting of the dismounted part. The utility model can reduce the labor intensity of workers and improve the dismantling efficiency.

Description

Pure hydraulic intelligent shaft dismantling device

Technical Field

The utility model relates to a hydraulic hammer for removing machine parts, in particular to a pure hydraulic intelligent shaft remover.

Background

The bolt and the pin shaft connection have the characteristics of simplicity, convenience and firmness, and are widely applied to various mechanical equipment. In the process of equipment maintenance and overhaul, damaged bolts and pin shafts are often required to be replaced. In small devices, such replacement is relatively easy. But in large plants, for example: engineering machinery, mining equipment, metallurgical equipment and the like are large in size, parts such as bolts and pin shafts are also large in size, and most large-scale equipment works in severe environments such as open air, dust, corrosion and the like for a long time, so that the parts are corroded, deformed and the like, the equipment needs to be maintained frequently, and the parts are difficult to remove. Clearly, the removal of these large parts by hand alone is a tremendous amount of labor and has safety concerns and inefficiencies.

SUMMERY OF THE UTILITY MODEL

Aiming at the problems of low efficiency and potential safety hazard in the process of removing large-scale equipment shaft parts, the utility model provides a pure hydraulic intelligent shaft remover which is used for removing large-scale shaft parts.

In order to solve the above technical problems, the present invention comprises: the device comprises an outer shell, a pure liquid type machine core, a punch, a reset spring, a taper sleeve device, a horizontal lifting hook, a vertical lifting hook, a rear handle, a left handle, a right handle, an electric control button, a rear seat spring and damping rubber. The electric control button is arranged in the rear handle at the rear end of the outer shell and used for controlling the on-off of an external oil source; the pure liquid type machine core is arranged in the inner cavity of the outer shell; the reset spring is coaxially arranged on the punch and used for resetting the punch so that the piston can strike the punch and the punch is tightly pressed on the detached part; the outer shell is lifted by a crane or a crane, the intelligent shaft remover is moved to a corresponding position by lifting, and corresponding punches are installed according to the diameters of different shaft parts; the taper sleeve device is used for positioning the horizontal shaft parts; under the drive of hydraulic oil, the piston reciprocates in the pure liquid type machine core to strike the punch, and the punch presses on the removed part to finish the removal work.

Has the advantages that: the pure liquid type machine core is driven by hydraulic pressure, has the characteristics of strong hitting power and high frequency, and can reduce the labor intensity of workers, improve the dismantling efficiency and protect the workers from being injured during dismantling operation. A spring is arranged between the pure liquid type machine core and the outer shell, so that vibration can be effectively reduced; the taper sleeve device is used for positioning the horizontal shaft parts, and can realize accurate removal; the starting and stopping actions are started and stopped in an electric control mode, and the device has the advantages of small volume, low cost, sensitive response and high integration degree.

Detailed Description

The following describes embodiments of the present invention in detail with reference to the drawings (fig. 1, 2, 3, 4, and 5).

A pure fluid pressure type intelligence axle type stripper includes: the device comprises an outer shell 1, a pure liquid type machine core 2, a punch 3, a return spring 4, a taper sleeve device 5, a horizontal lifting hook 6, a vertical lifting hook 7, a rear handle 8, left and right side handles 9, an electric control button 10, a backseat spring 11, damping rubber 12 and a piston 13.

The external oil source is controlled through the electric control button 10, when the electric control button 10 is pressed down, the external oil source can enter the pure liquid type machine core 2, at the moment, hydraulic oil is fully filled in the cavities of the front cavity Q and the rear cavity H, and the front cavity Q is always in a high-pressure state. When the rear cavity H enters high-pressure oil with the same pressure as the front cavity Q, because the area S2 is larger than the area S1, the thrust of the rear cavity H to the piston 13 is larger than the thrust of the front cavity Q to the piston 13, the piston 13 can move towards the direction M, the piston 13 impacts the punch 3, and the punch 3 impacts the shaft part to be removed through the taper sleeve device 5, so that the purpose of removing is achieved; the taper sleeve device 5 consists of an outer sleeve 5.1 and an inner sleeve 5.2, matching surfaces of the outer sleeve 5.1 and the inner sleeve 5.2 are conical surfaces, and the taper fit has a self-locking function; when the rear cavity H is communicated with the oil return, the rear cavity H is in a low-pressure state, the front cavity Q is always in a high-pressure state, the acting force of the front cavity Q on the piston 13 is larger than that of the rear cavity H on the piston 13, then the piston 13 can move towards the direction N, the piston 13 is far away from the punch 3, and the punch 3 circularly strikes the disassembled shaft part until the disassembled shaft part is disassembled.

The utility model is not limited to the above-described embodiments, and other variations within the knowledge of a person skilled in the art are within the scope of the utility model.
