Description

Technical Field

[0001] This utility model relates to the technical field of hydraulic oil replacement equipment for construction machinery, specifically to a quick hydraulic oil replacement device for construction machinery. Background Technology

[0002] Construction machinery is a general term for mechanical equipment used in engineering construction and urban and rural construction. In China, it is also known as "construction machinery" or "engineering machinery." It consists of various types of machinery, including excavators, earthmoving and transport machinery, compaction machinery, engineering cranes, piling machinery, road machinery, concrete machinery, concrete product machinery, reinforced concrete and prestressed concrete machinery, decoration machinery, and aerial work platforms. Engineering machinery is an important part of the equipment manufacturing industry. In general, it refers to the mechanical equipment necessary for comprehensive mechanized construction projects such as earthmoving, road construction and maintenance, mobile lifting and loading operations, and various building projects. Construction machinery generally uses hydraulic oil, which needs to be changed regularly over a long period of time. However, the current method of changing hydraulic oil in construction machinery involves workers directly pouring hydraulic oil from a hydraulic oil container into the hydraulic oil tank, which is prone to spillage and is not convenient. Therefore, we propose a quick hydraulic oil changing device for construction machinery. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides a quick hydraulic oil replacement device for construction machinery.

[0004] The technical solution adopted by this utility model to solve its technical problem is a quick hydraulic oil replacement device for construction machinery, including a housing. The outer wall surface of the housing is equipped with a pump body for hydraulic oil transportation, and the discharge end of the pump body is equipped with a flow valve for measurement. The end of the flow valve away from the pump body and the inlet end of the pump body are both screwed with hoses for guiding flow.

[0005] A battery box electrically connected to the pump body is inserted into the outer wall surface of the housing, and a plug electrically connected to the housing is mounted on the outer wall surface of the battery box. A locking block that is inserted into the housing is integrally constructed on the outer wall surface of the battery box, and there are two sets of locking blocks. A pin hole is opened on the outer wall surface of the locking block, and a rotating rod that is screwed into the pin hole is screwed onto the outer wall surface of the housing, and there are two sets of rotating rods.

[0006] By adopting the above technical solution, when changing the hydraulic oil of construction machinery, the pump body on the outside of the machine casing can operate and easily draw the hydraulic oil from the inside of the hydraulic oil tank through the hose, and then transport the hydraulic oil into the hydraulic oil tank inside the construction machinery through the hose at the other end. At the same time, the flow valve at the pump body outlet can measure the amount of hydraulic oil added in real time, so as to facilitate the operator to control the amount of hydraulic oil added, and to add it quickly and accurately.

[0007] During the use of the pump, the battery box on the outside of the housing is electrically connected to the housing via a plug, which facilitates the provision of power to the pump. This makes the pump portable and allows it to operate without an external power source. At the same time, the battery box on the outside of the housing can be removed by simply unscrewing the screw on the outside of the housing, making it easy to disassemble and replace the battery box. The disassembly and assembly are simple and convenient.

[0008] Specifically, the outer wall surface of the housing is equipped with a controller electrically connected to the pump body, and the outer wall surface of the housing is equipped with a display screen electrically connected to the flow valve.

[0009] By adopting the above technical solution, the controller can easily control the operation of the pump body, while the display screen can easily display the data measured by the flow valve, so as to facilitate personnel observation.

[0010] Specifically, the bottom surface of the battery box is provided with a T-shaped groove that engages with the housing.

[0011] By adopting the above technical solution, the T-shaped groove at the bottom of the battery box fits into the protrusion on the housing, which facilitates the improvement of the stability of the battery box when it is snapped onto the outer periphery of the housing, enabling the battery box to provide power support to the pump body more stably.

[0012] Specifically, the battery box has a groove on the side near the housing that fits into the housing, and there are multiple sets of grooves. The outer wall surface of the battery box has a pull groove for lifting, and there are multiple sets of pull grooves.

[0013] By adopting the above technical solution, the grooves on the outer periphery of the battery box make it easier to disassemble and assemble the battery box, and the grooves on the battery box fit together with the protrusions on the casing, which further improves the stability of the battery box during installation.

[0014] Specifically, the outer periphery of the housing is provided with a pull hole for lifting.

[0015] By adopting the above technical solution, the drilling makes it easy and convenient to lift the casing, making it easy to use.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The technical solution of this application, through the design of the pump body, flow valve, and hose, enables the pump body on the outside of the machine casing to operate and conveniently draw hydraulic oil from the hydraulic oil tank through the hose when changing the hydraulic oil in construction machinery. The hydraulic oil is then transported into the hydraulic oil tank inside the construction machinery through the hose at the other end. At the same time, the flow valve at the pump body's discharge end can measure the amount of hydraulic oil added in real time, so that the operator can control the amount of hydraulic oil added, and add it quickly and accurately.

[0018] 2. The technical solution of this application, through the design of battery box, plug, clip, pin hole and screw rod, allows the battery box on the outside of the housing to be electrically connected to the housing through the plug during the use of the pump body, which facilitates the provision of power to the pump body. This makes the pump body easy to carry and can operate without an external power source. At the same time, the battery box on the outside of the housing can be removed by simply unscrewing the screw rod, which makes it easy to disassemble and replace the battery box. The disassembly and assembly are simple and convenient. Attached Figure Description
