Description

Technical Field

[0001] This utility model relates to the field of hydraulic drilling machine technology, and in particular to a multi-stage thrust bearing protection device for hydraulic rotary drilling machines. Background Technology

[0002] A hydraulic drilling machine is a drilling device with a hydraulic system as its core drive unit. It operates by driving a rotating mechanism or spindle through oil pressure. It mainly consists of a hydraulic system, a power unit, and an operating table. It uses high-pressure oil to drive the rotating mechanism or directly push the spindle to feed the cutting tool. For example, a hydraulic rotary drilling rig achieves continuously variable transmission through an oil pump and an oil motor, replacing the traditional gearbox; a hydraulic drilling machine uses an oil pressure system to drive the spindle to complete drilling, reaming, and other processing operations.

[0003] The existing technical solutions mentioned above have the following drawbacks: the thrust bearing used inside the hydraulic drilling machine lacks a protective structure. When the hydraulic drilling machine is working, the surrounding environment is relatively harsh, and some stains, gravel or dust can easily enter the bearing, affecting normal use. Utility Model Content

[0004] The purpose of this invention is to provide a protection device for the multi-stage thrust bearing of a hydraulic swivel machine.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A multi-stage thrust bearing protection device for a hydraulic swivel machine includes a bearing body. A first locking cover and a second locking cover are provided on the outer side of the bearing body. A first connecting member is fixedly connected to the outer side of the first locking cover. A limit groove is reserved on the inner side of the first connecting member. A first connecting piece is provided on the outer side of the first locking cover. A second connecting piece is fixedly connected to the outer side of the second locking cover. A limit rod is fixedly connected to the outer side of the second connecting piece. A second connecting piece is provided on the outer side of the second locking cover.

[0007] By adopting the above technical solution, a protective structure is added to the outside of the bearing body. The locking covers at both ends can be connected and installed through the structure between the locking cover and the connecting piece. At the same time, a connecting piece is added to the outside of each locking cover. The locking cover and the connecting piece are installed and protected on the inside of the bearing body, and the connecting piece is sleeved on the outside of the bearing body for protection. There will be no mutual friction or interference between the structures, which can ensure that the bearing can rotate normally.

[0008] Furthermore, the first locking cover has a first countersunk hole inside, the first connector has a first threaded hole inside, the first connecting member has a second threaded hole inside, the second locking cover has a second countersunk hole and a third countersunk hole inside, and the second connecting member has a third threaded hole inside.

[0009] By adopting the above technical solution, the locking cover and the connecting parts are connected by fixing bolts and threaded holes, which enables quick disassembly and assembly and facilitates installation and use.

[0010] Furthermore, both the first locking cover and the second locking cover are placed inside the bearing body, the limiting groove and the limiting rod are engaged, the first connecting member is placed outside the first connecting member and is in contact with the first locking cover, the second connecting member is placed outside the second connecting member and is in contact with the second locking cover, and both the first connecting member and the second connecting member are sleeved on the outside of the bearing body.

[0011] By adopting the above technical solution, and by installing a connector that is fitted onto the outside of the bearing body, the outside of the bearing body can be protected.

[0012] Furthermore, the connecting bolt extends through the third countersunk hole to the interior of the first threaded hole, the first threaded hole and the connecting bolt are threadedly connected, the first fixing bolt extends through the first countersunk hole to the second threaded hole and is threadedly connected to the second threaded hole, and the second fixing bolt extends through the second countersunk hole to the interior of the third threaded hole and is threadedly connected to the third threaded hole.

[0013] By adopting the above technical solution, the structure that uses bolts and threaded holes for connection can be easily disassembled and assembled.

[0014] In summary, the beneficial technical effects of this utility model are as follows:

[0015] It employs a locking cover, connectors, fittings, bolts, and threaded holes. A locking cover and a fitting that connects to the locking cover are added to the outside of the bearing body. The locking cover and the connector can be mated together for installation. The fitting is then sleeved onto the outside of the bearing body to protect the inner and outer parts, preventing dust and dirt from the working environment from entering the internal structure of the bearing, extending the bearing's service life, ensuring stable operation, and providing a convenient user experience.
