Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic coupling disassembly and assembly devices, and particularly relates to a new type of hydraulic coupling disassembly and assembly auxiliary device. Background Art

[0002] When the motor is overhauled, the coupling needs to be disassembled. Some equipment uses a non-rigid hydraulic coupling (i.e., a hydraulic coupling), and there are the following problems in the disassembly of this coupling:

[0003] First, since the shell of the non-rigid hydraulic coupling is made of aluminum and has insufficient hardness, existing shaft pulling tools cannot be used for disassembly and assembly, otherwise the shell will be damaged.

[0004] Second, since there is oil inside the non-rigid hydraulic coupling, disassembly and assembly cannot be carried out by means of high-temperature heating.

[0005] Third, in order to meet the production needs, the prior art can only disassemble and assemble the non-rigid hydraulic coupling destructively, and the existing shaft puller in the prior art cannot simultaneously meet the disassembly and assembly requirements of non-rigid hydraulic couplings of different models. Summary of the Utility Model

[0006] In view of the problems existing in the prior art, the utility model provides a new type of hydraulic coupling disassembly and assembly auxiliary device, and the specific content of the utility model includes the following:

[0007] A new type of hydraulic coupling disassembly and assembly auxiliary device includes a connecting flange, an auxiliary pipe and a chassis.

[0008] The hole specifications, quantity and positions of the connecting flange correspond to those of the holes on the coupling flange of the hydraulic coupling.

[0009] The diameter of the auxiliary pipe is larger than the diameter of the end shaft of the hydraulic coupling and smaller than the diameter of the circle where the centers of multiple holes on the connecting flange are located; the auxiliary pipe includes a first end and a second end, and the first end of the auxiliary pipe is connected to one side surface of the connecting flange; a first reserved hole is arranged on the pipe wall of the auxiliary pipe near the second end.

[0010] The chassis is arranged at the second end of the auxiliary pipe, and a second reserved hole is opened at the center of the chassis.

[0011] Preferably, the auxiliary pipe is perpendicularly connected to one side surface of the connecting flange, and the center of the connecting flange is located on the straight line where the central axis of the auxiliary pipe is located.

[0012] Preferably, the center of the second reserved hole is located on the straight line where the central axis of the auxiliary pipe is located.

[0013] Preferably, the connecting flange, auxiliary pipe and chassis are all made of stainless steel, and the wall thickness of the auxiliary pipe is not less than 5 mm.

[0014] Preferably, the inner diameter of the connecting flange is not less than the inner diameter of the coupling flange of the hydraulic coupling.

[0015] Preferably, the outer diameter of the connecting flange is larger than the outer diameter of the hydraulic coupling coupling flange.

[0016] Preferably, the first reserved hole is a semi-elliptical hole obliquely opened on the tube wall of the auxiliary tube close to the second end, which can accommodate jacks of different sizes.

[0017] Beneficial effects of the utility model:

[0018] When the novel hydraulic coupling disassembly and assembly auxiliary device of the utility model is used, the connecting flange is first fixedly installed between the two flanges of the hydraulic coupling coupling by bolts, and the auxiliary pipe is sleeved on the outside of the axis (i.e., the power output shaft of the hydraulic coupling) at the center of the hydraulic coupling coupling flange, and the first reserved hole is set downward. The length of the auxiliary pipe is greater than the length of the shaft extension, and the first reserved hole is located at the end of the auxiliary pipe that exceeds the center axis of the hydraulic coupling coupling flange.

[0019] When the hydraulic coupler needs to be separated from the motor shaft, the device can be used in conjunction with a jack. The method of use is: extend the upper end of the jack from the first reserved hole into the auxiliary pipe, and press against the inner wall of the auxiliary pipe, and continue to lift the top of the jack so that the auxiliary pipe is subjected to an upward force, which is then transmitted to the hydraulic coupler through the connecting flange. When the force is large enough, the connection between the hydraulic coupler and the motor shaft will become loose, and the two will be separated. The device is connected to the hydraulic coupler coupling through a connecting flange and multiple bolts, and then force is applied to the auxiliary pipe through the jack, and force is transmitted to the hydraulic coupler through the connecting flange, so that the force is relatively more uniform, avoiding damage to the outer shell of the hydraulic coupler caused by the jack directly pushing the hydraulic coupler.

[0020] When the hydraulic coupler needs to be separated from the motor shaft, the device can also be used in conjunction with a shaft puller, and the method of use is: insert the central axis of the shaft puller's claws into the auxiliary tube of the device through the second reserved hole, so that it abuts against the shaft of the hydraulic coupler inside the auxiliary tube. Then fix the claws of the shaft puller on the circumferential side of the connecting flange of the device and hold it tightly, operate the shaft puller to make its central axis continuously move into the auxiliary tube, and then push out the motor shaft.

[0021] Using the device of the present utility model, not only can the disassembly of the hydraulic coupling be realized, but also damage to the housing of the hydraulic coupling can be avoided. Moreover, according to actual needs, the way of separating the hydraulic coupling from the motor shaft can be selected to adapt to different working environments. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present utility model will be described in detail below with reference to the drawings and specific embodiments. The embodiments shown below do not limit the content of the utility model recorded in the claims in any way. In addition, all the contents shown in the following embodiments are not limited to what is necessary for the solution of the utility model recorded in the claims.

[0026] Refer to the attached Figures 1 - 3 , a new type of hydraulic coupling disassembly and assembly auxiliary device, including a connecting flange 1, an auxiliary pipe 2 and a chassis 3,

[0027] The hole specifications, quantity and positions of the connecting flange 1 correspond to the hole specifications, quantity and positions of the holes on the coupling flange of the hydraulic coupling;

[0028] The diameter of the auxiliary pipe 2 is larger than the diameter of the end shaft of the hydraulic coupling and smaller than the diameter of the circle where the centers of multiple holes on the connecting flange 1 are located; the auxiliary pipe 2 includes a first end and a second end, and the first end of the auxiliary pipe 2 is connected to one side surface of the connecting flange 1; a first reserved hole 4 is arranged on the pipe wall of the auxiliary pipe 2 near the second end;

[0029] The chassis 3 is arranged at the second end of the auxiliary pipe 2, and a second reserved hole 5 is opened at the center of the chassis 3.

[0030] In some embodiments of the present utility model, the auxiliary pipe 2 is perpendicularly connected to one side surface of the connecting flange 1, and the center of the connecting flange 1 is located on the straight line where the central axis of the auxiliary pipe 2 is located.

[0031] In some embodiments of the present utility model, the center of the second reserved hole 5 is located on the straight line where the central axis of the auxiliary pipe 2 is located.

[0032] In some embodiments of the present utility model, the connecting flange 1, the auxiliary pipe 2 and the chassis 3 are all made of stainless steel, and the wall thickness of the auxiliary pipe 2 is not less than 5 mm.

[0033] In some embodiments of the present utility model, the inner diameter of the connecting flange 1 is not less than the inner diameter of the flange of the hydraulic coupling shaft coupling.

[0034] In some embodiments of the present utility model, the outer diameter of the connecting flange 1 is greater than the outer diameter of the flange of the hydraulic coupling shaft coupling.

[0035] In some embodiments of the present utility model, the first reserved hole 4 is a semi-elliptical hole obliquely opened on the wall of the auxiliary pipe 2 near the second end, which can accommodate jacks of different sizes.

[0036] When the novel hydraulic coupling disassembly and assembly auxiliary device of the present utility model is in use, first, the connecting flange 1 is fixedly installed between the two flanges of the hydraulic coupling shaft coupling through bolts, and the auxiliary pipe 2 is sleeved outside the shaft (i.e., the power output shaft of the hydraulic coupling) at the center of the flange of the hydraulic coupling shaft coupling, and at the same time, the first reserved hole 4 is arranged downward. The length of the auxiliary pipe 2 is greater than the length of the shaft extending outwards, and the first reserved hole 4 is located at the end of the auxiliary pipe 2 that extends beyond the central axis of the flange of the hydraulic coupling shaft coupling.

[0037] When it is necessary to separate the hydraulic coupling from the motor shaft, this device can be used in cooperation with a jack. The usage method is as follows: The upper end of the jack is inserted into the auxiliary pipe 2 from the first reserved hole 4 and abuts against the inner wall of the auxiliary pipe 2. Continuously lift the position of the top of the jack, so that the auxiliary pipe 2 receives an upward force, and then transmits it to the hydraulic coupling through the connecting flange 1. When the force is large enough, the connection between the hydraulic coupling and the motor shaft will become loose, and then the two will be separated. This device is connected to the hydraulic coupling shaft coupling through the connecting flange 1 and multiple bolts, and then a force is applied to the auxiliary pipe 2 through the jack, and the force is transmitted to the hydraulic coupling through the connecting flange 1, which can make the force relatively more uniform and avoid damage to the outer shell of the hydraulic coupling caused by directly jacking the hydraulic coupling with the jack.

[0038] When it is necessary to separate the hydraulic coupler from the motor shaft, this device can also be used in conjunction with a shaft puller. The usage method is as follows: Insert the central shaft of the claw of the shaft puller through the second reserved hole 5 into the auxiliary pipe 2 of this device, so that it abuts against the shaft of the hydraulic coupler inside the auxiliary pipe 2. Then fix the claw of the shaft puller on the circumferential side of the connecting flange 1 of this device and grip it tightly. Operate the shaft puller to continuously move its central shaft into the auxiliary pipe 2, thereby ejecting the motor shaft. This device is connected to the hydraulic coupler coupling through the connecting flange 1 and multiple bolts. Then, the claw of the shaft puller grips the connecting flange 1 tightly, and the force is transmitted to the shaft of the hydraulic coupler through the central shaft of the claw, which can avoid the direct contact between the claw and the outer shell of the hydraulic coupler, and avoid the damage to the outer shell of the hydraulic coupler caused by directly jacking the hydraulic coupler with a jack.

[0039] Using the device described in the present utility model, not only can the disassembly of the hydraulic coupler be realized, but also the damage to the outer shell of the hydraulic coupler can be avoided. Moreover, according to actual needs, the method of separating the hydraulic coupler from the motor shaft can be selected, which can adapt to different working environments.
