Description

Technical Field

[0001] The utility model belongs to the technical field of plunger pump auxiliary operation, and in particular relates to an auxiliary device for the operation of a plunger pump. Background Art

[0002] The plunger pump is an important device in the hydraulic system. It relies on the reciprocating motion of the plunger in the cylinder to change the volume of the sealed working chamber to achieve oil suction and oil pressure. The plunger pump has the advantages of high rated pressure, compact structure, high efficiency and convenient flow regulation. It is widely used in high pressure, large flow and flow regulation occasions, such as hydraulic presses, engineering machinery and ships. However, because the pump body of the plunger pump is heavy and the plunger pump is often connected to the oil drum, the overall weight is heavier, so it is more cumbersome to move it out of or into the electric control box, lift the plunger pump to fill the oil drum, etc. The process is relatively cumbersome. Therefore, whether it is possible to provide an auxiliary device for the plunger pump that can easily lift the plunger pump, push the plunger pump and the oil drum and move it out of the electric control box is a technical problem that needs to be solved by the utility model. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides an auxiliary device for the plunger pump, which can easily realize the movement of the oil drum with the plunger pump and the replacement of the oil in the oil drum, simplifying the operation steps and not requiring excessive manpower.

[0004] The utility model discloses an auxiliary device for working a plunger pump, comprising a hoisting mechanism and a sliding bottom plate; an oil barrel for the plunger pump is installed on the sliding bottom plate so as to move the plunger pump and the oil barrel into or out of the electric control box; a plurality of lifting rings are arranged on the outer top of the plunger pump, and the hoisting mechanism controls the lifting and lowering of the plunger pump above the oil barrel by connecting the plurality of lifting rings.

[0005] Optimized, the lifting mechanism includes a support frame, a plurality of fixed pulleys installed on the top rod of the support frame, a winder installed on the side rod of the support frame, a rope, a hook, a chain, and a lifting buckle; the end of the rope is fixed and wound and stored on the winder, and the middle position of the rope is respectively passed through the top of the plurality of fixed pulleys; the starting end of the rope hangs down, the hook is installed at the starting end of the rope, and a plurality of the lifting buckles are respectively connected to the hook through a plurality of the chains, and a plurality of the lifting rings are hooked by the lifting buckle to connect the plunger pump to the lifting mechanism.

[0006] Further optimized, the winder is installed on the support frame through a first bracket.

[0007] Further optimized, the sliding base plate includes a supporting base plate and a plurality of rollers installed on the bottom of the supporting base plate.

[0008] For further optimization, a solenoid valve is installed in the electric control box, one end of the solenoid valve is connected to the oil outlet of the plunger pump through an oil inlet pipe, and the other end of the solenoid valve is connected to the device to be lubricated through an oil outlet pipe.

[0009] For further optimization, a controller and an alarm buzzer are also provided in the electric control box, a liquid level sensor is installed at the bottom of the plunger pump, the liquid level sensor, the solenoid valve, the plunger pump and the buzzer are all connected to the controller, and the working process of the plunger pump is supervised by the controller.

[0010] The beneficial effects of the utility model are:

[0011] The operating steps are simplified. In the past, the plunger pump was lifted manually and then oil was poured into the oil barrel. Now, the plunger pump can be separated from the oil barrel by directly controlling the winder and driving the rope to be retracted through two fixed pulleys in turn. A liquid level gauge is set on the inside of the plunger pump to monitor the oil level in the oil barrel in real time. When the oil level is too low, the controller controls the buzzer to alarm, thereby serving as an oil level warning. There is no need to expend too much effort. The oil barrel is placed on a sliding bottom plate and can be easily moved by pushing the oil barrel. BRIEF DESCRIPTION OF THE DRAWINGS
