In daily inspection and maintenance operations, it is necessary to disassemble and maintain the wheels, bearings, impellers, etc. During the operation, a puller is required to disassemble the bearings and replace spare parts. When the shaft is long or the bearing is installed deep, the puller cannot be used to pull out the bearing due to the short distance of the pull claws. Manual pulling is time-consuming and laborious, which seriously affects the progress of the inspection and maintenance work. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a digital display multi-pulling claw split hydraulic puller to solve the technical problem that when the rotating shaft is long or the bearing is installed deep, the puller cannot be used to pull out the bearing due to the short distance between the pulling claws, and manual pulling out is time-consuming and labor-intensive, which seriously affects the progress of inspection and maintenance work.

[0004] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0005] A digital display type multi-claw split hydraulic puller, comprising: a hydraulic cylinder, a puller ring, a thimble, a puller tab, a puller claw, a hydraulic line, a hydraulic pump body, a handle and a pressure gauge, wherein the handle is mounted on the hydraulic pump body, one end of the hydraulic line is connected to the hydraulic pump body, and the other end is connected to the hydraulic cylinder body, and the pressure gauge is mounted at the inlet of the hydraulic cylinder body. The puller ring is mounted on the hydraulic cylinder body.

[0006] Preferably, one end of the pull tab is connected to the pull ring, and the other end is connected to the pull claw, and the ejector pin is installed at the lower part of the hydraulic cylinder body.

[0007] Preferably: the digital display multi-claw split hydraulic puller is equipped with two to three sets of claws.

[0008] Preferably, the hydraulic line is detachably connected to the hydraulic cylinder body.

[0009] The utility model has the following beneficial effects:

[0010] Bearing pumps are widely used in industrial production. In daily inspection and maintenance operations, it is necessary to disassemble and maintain wheels, bearings, impellers, etc. During the operation, a puller is needed to disassemble and replace spare parts of bearings, etc. When the shaft is long or the bearing is installed deep, the puller cannot be used to pull out the bearing due to the short distance between the pulling claws. Manual pulling out is time-consuming and labor-intensive, which has a serious impact on the progress of inspection and maintenance operations. The existing puller has a limited pulling range and cannot meet the requirements of the operation. The utility model provides a puller that can adapt to the disassembly and pulling out of bearings of various depths and sizes. At the same time, it can display the puller hydraulic pressure value in real time, accurately control the pulling force, and prevent the occurrence of barbaric operations. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The above description is only an overview of the technical solution of the utility model. In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the following is a detailed description of the preferred embodiments of the utility model in conjunction with the accompanying drawings.

[0012] Figure 1 It is the overall structure diagram of the utility model.

[0013] Legend: 1. Hydraulic cylinder; 2. Puller ring; 3. Ejector pin; 4. Pull tab; 5. Pull claw; 6. Hydraulic line; 7. Hydraulic pump body; 8. Handle; 9. Pressure gauge.

[0014] The embodiment of the present application provides a digital display multi-claw split hydraulic puller to effectively solve the technical problem that when the rotating shaft is long or the bearing is installed deep, the puller cannot be used to pull out the bearing due to the short distance between the claws, and manual pulling out is time-consuming and labor-intensive, which seriously affects the progress of inspection and maintenance work.

[0015] The overall idea of ​​the technical solution in the embodiment of the present application is as follows:

[0016] like Figure 1 As shown, in view of the problems existing in the prior art, the utility model provides a digital display type multi-claw split hydraulic puller, comprising: a hydraulic cylinder body 1, a puller ring 2, a thimble 3, a pull piece 4, a pull claw 5, a hydraulic line 6, a hydraulic pump body 7, a handle 8 and a pressure gauge 9, wherein the handle 8 is installed on the hydraulic pump body 7, one end of the hydraulic line 6 is connected to the hydraulic pump body 7, and the other end is connected to the hydraulic cylinder body 1, the pressure gauge 9 is installed at the inlet of the hydraulic cylinder body 1, the puller ring 2 is installed on the hydraulic cylinder body 1, one end of the pull piece 4 is connected to the puller ring 2, and the other end is connected to the pull claw 5, and the thimble 3 is installed at the lower part of the hydraulic cylinder body 1;

[0017] The puller is equipped with two sets of pulling claws 5 or three sets of pulling claws 5, and each set of pulling claws 5 is equipped with multiple pulling claws 5 of different lengths, which can be switched according to the needs of disassembling bearings with different depths. The length specifications of the pulling claws 5 are 150mm, 250mm, 350mm, etc.; multiple pulling claws 5 of different lengths can be installed on the puller for a long time, and can also be disassembled and stored at any time. The hydraulic line 6 is detachably connected to the hydraulic cylinder body 1, and the hydraulic line 6 and the hydraulic cylinder body 1 are detachable and easy to carry. The pressure gauge 9 is used to accurately display the pulling force to prevent rough operation caused by incorrect pulling angles, thereby damaging the bearings.

[0018] Working principle: Select the pulling claw 5 of appropriate length according to the needs of different disassembly depths of bearings, install the puller on the bearing disassembly equipment, press the handle 8 to start pulling the bearing, and pay attention to the pressure changes of the pressure gauge 9 during the process. If the pulling force is too large, adjust the installation angle of the puller in time and perform the pulling operation again until the bearing is disassembled.

[0019] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
