Rotary table hydraulic oil tank protection device for insulated boom truck

Abstract

The utility model relates to the technical field of rotary table parts, and discloses a rotary table hydraulic oil tank protection device for an insulated boom truck. The rotary table hydraulic oil tank protection device for the insulated boom truck comprises a shell, a mounting groove is formed in the surface of the shell, a connecting column is fixedly installed on the inner side of the shell, an inner pipe is fixedly installed on the inner side of the connecting column, a connecting hole is formed in the surface of the inner pipe, and the contact face of a silica gel plate is located in the center of the mounting groove and the connecting hole. During use, a pipeline can penetrate through the shell and the inner pipe through the mounting grooves and the connecting holes and is located between the silica gel plates, and due to the fact that silica gel materials have certain deformation capacity, the silica gel plates can deform under the limitation of the appearance of the connecting pipe; in this way, gaps between the pipeline and the mounting groove and between the pipeline and the connecting hole can be reduced while the pipe string hook shell and the inner pipe are conveniently connected, and therefore the probability that dust and marl possibly fall to the position above the oil tank through the gaps is reduced.

Description

Technical Field

[0001] The utility model relates to the technical field of turntable parts, in particular to a turntable hydraulic oil tank protection device for an insulating bucket arm vehicle. Background Art

[0002] The turntable is driven by hydraulic means. The hydraulic equipment of the turntable is connected to the hydraulic oil tank through pipelines. The main function of the hydraulic oil tank is to store oil. In addition, it also plays the role of heat dissipation, impurity precipitation and air escape from the oil. According to whether the oil tank liquid level is connected to the atmosphere, the oil tank can be divided into open type and closed type. Open oil tanks are used in general hydraulic systems; closed oil tanks are used in underwater hydraulic systems and hydraulic systems with strict requirements on working stability and noise.

[0003] The existing referenceable Chinese utility model patent with announcement number: CN221003494U discloses a protective cover, including a cover body and a cap body connected to the cover body, the cover body including a first connection part that cooperates with the cap body and a second connection part that abuts against the surface of an object, the first connection part is provided with a mounting groove, the bottom of the mounting groove is provided with a deformable abutting end, and a mounting hole located at the abutting end for the locking member to pass through. The utility model solves the problem that after the screw is installed and connected, it is easily corroded by moisture and rusted when exposed to the external environment. Through the structural setting of the utility model, the screw generates pressure during the installation process, and the abutting end is elastically deformed to disperse the pressure, thereby enhancing the pressure resistance of the cover body and extending the service life of the protective cover, saving resources, and improving the user experience.

[0004] At present, the hydraulic oil tank is located inside the turntable. The turntable is provided with an open structure for the pipeline to pass through. The pipeline is connected to the hydraulic oil tank through a metal connecting pipe. At the same time, foreign objects such as leaves and branches accumulated on the turntable may be transmitted to the turntable support surface through the open structure. Foreign objects accumulated on the top of the oil tank may cause damage to the oil tank. The connection is exposed and may be damaged by the impact of heavy objects. At present, the opening of the turntable is generally closed by a protective cover. During use, due to the influence of the pipeline direction, a certain gap will be left between the pipeline opening structure and the pipeline. Dust and mud may fall through the gap to the top of the oil tank and cause corrosion to the oil tank. Utility Model Content
