Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

In one embodiment, referring to fig. 1, fig. 4 and fig. 5, a cleaning pump apparatus 100, the cleaning pump apparatus 100 includes: a base 110, a motor 120, a power pump 130, and a control valve 140. The motor 120 is mounted on the base 110. The power pump 130 comprises a pump shell 131 and a movable plug 134, the movable plug 134 is in driving fit with the output shaft 121 of the motor 120, and the pump shell 131 is provided with an output port 133 and an input port 132 for communicating with a supply device. A movable plug 134 is movable within the pump housing 131 for drawing cleaning agent from the inlet port 132 and for forcing it out of the outlet port 133. One end of the control valve 140 is communicated with the output port 133, the other end of the control valve 140 is communicated with the spray gun 300, and the control valve 140 is used for controlling the output port 133 to be connected with or disconnected with the spray gun 300.

In the cleaning pump device 100, the input port 132 on the pump shell 131 is communicated with the cleaning agent device in the cleaning process; then, one end of the control valve 140 is communicated with one end of the spray gun 300 to complete the assembly of the cleaning system; then, the motor 120 is started to drive the movable plug 134 to reciprocate in the pump housing 131, so that the cleaning agent is sucked from the input port 132 and is pressed out from the output port 133 to the control valve 140; the control valve 140 is opened, so that the output port 133 is communicated with the spray gun 300, the cleaning agent in the control valve 140 is conveyed into the spray gun 300, the cleaning agent is sprayed onto the outer locking turnout part through the spray gun 300 by an operator, the outer locking turnout is kept clean, and the driving safety is ensured. Meanwhile, because the motor 120, the power pump 130 and the control valve 140 are all integrated on the base 110, when the outer locking turnout at different positions needs to be cleaned, an operator only needs to move the base 110 to realize the movement of the whole cleaning pump device 100, thereby greatly facilitating the cleaning operation of the outer locking turnout, reducing the mobility of the cleaning operation and improving the cleaning efficiency.

It should be noted that the cleaning agent of the present embodiment may be various, such as: the cleaning agent can be water-based, semi-water-based, solvent-based and the like; of course, the cleaning agent may be an oily substance. When the cleaning agent is an oily substance, the cleaning agent can provide power oil for a cleaning system and can also be used for spraying and cleaning an external locking turnout part. After the cleaning agent is used for cleaning positions of externally locking turnout latch hooks, locking frames, locking irons, locking rods and the like, the cleaning agent can be used for avoiding being coated with engine oil for lubrication. In addition, the cleaning agent is used as power oil, so that the service life of hydraulic equipment is not affected. In addition, the supply equipment can be a tank, a basin, a cylinder, a barrel, a box and the like, and the interior of the supply equipment is filled with cleaning agents.

Specifically, referring to fig. 4, the cleaning agent is prepared from at least one of kerosene, diesel oil, and engine oil. Meanwhile, the output shaft 121 of the motor 120 is provided with a cam 123, and one end of the movable plug 134 abuts against the cam 123. When the motor 120 is activated, the output shaft 121 rotates, which rotates the cam 123, and the rotating cam 123 moves the movable plug 134 up and down, so that the cleaning agent is sucked from the input port 132 and pressed out of the output port 133.

It should be noted that, the output port 133 and the input port 132 on the pump housing 131 are provided with one-way valve plugs, so that the flow direction of the cleaning agent in the input port 132 and the output port 133 respectively keeps one-way flow, and the cleaning agent can stably flow in from the input port 132 and flow out from the output port 133. Meanwhile, the present embodiment does not specifically limit the type of the control valve 140, and only needs to satisfy the connection/disconnection between the output port 133 and the spray gun 300.

Specifically, referring to fig. 2, the control valve 140 is a three-way reversing valve, and when a handle of the three-way reversing valve is pulled to a working mode, the cleaning agent can stably flow into the spray gun 300; when the handle of the three-way reversing valve is pulled to the unloading mode, the power pump 130 and the spray gun 300 are unloaded and flow back completely.

Further, referring to fig. 2, the purge pump apparatus 100 further includes a relief valve 150. The overflow valve 150 is installed on the base 110, and the control valve 140 is communicated with the output port 133 through the overflow valve 150, so that it can be known that the overflow valve 150 is additionally arranged between the output port 133 and the control valve 140, when the fluid pressure of the cleaning agent is higher than the overflow pressure, the cleaning agent automatically flows back to the cleaning agent equipment through the overflow valve 150, for example: in the tank 200, as such, the flow pressure in the relief valve 150 is controlled to be kept stable by the relief valve 150.

Specifically, the operating pressure of the relief valve 150 is 2Mpa, and the relief pressure of the relief valve 150 is 8 Mpa.

It should be noted that the relief valve 150 is also called a safety valve to ensure safe operation of the pressure pipeline and the pressure vessel. When the system pressure exceeds the specified value, the safety valve is opened, and a part of gas/liquid in the system is discharged, so that the system pressure does not exceed the allowable value, and the system is ensured not to have accidents due to overhigh pressure. Since the relief valve 150 is an existing device, which is not an object of improvement of the present embodiment, the specific internal structure of the relief valve 150 can be directly referred to in the existing literature, and is not described in detail here.

Further, referring to fig. 3, the washing pump device 100 further includes a check valve 160. The check valve 160 and the overflow valve 150 are connected in series to the output port 122, so that the flow direction of the cleaning agent in the system is limited by the check valve 160, and the cleaning agent is prevented from flowing back on the system.

Similarly, the internal structure of the check valve 160 is also conventional and will not be described herein.

It should be noted that, referring to fig. 3, the communication sequence of the check valve 160, the output port 133 and the relief valve 150 of the present embodiment includes two types, such as: the output port 133, the check valve 160 and the overflow valve 150 are communicated in sequence; alternatively, the output port 133, the relief valve 150, and the check valve 160 are communicated in this order. In this embodiment, the communication sequence of the check valve 160 and the overflow valve 150 at the output port 133 is not particularly limited, and only the one-way flow of the cleaning agent among the check valve 160, the output port 133 and the overflow valve 150 is required.

In one embodiment, referring to fig. 2, the motor 120 and the power pump 130 are respectively located at two opposite sides of the base 110. The relief valve 150 is located on the same side of the base 110 as the motor 120. The power pump 130, the check valve 160 and the connection pipe 170 are located on the same side of the base 110. Therefore, in the present embodiment, the cleaning pump device 100 is divided into two parts, one part is the motor 120 and the overflow valve 150; the other part is a power pump 130, a one-way valve 160 and a connecting pipe 170, and the two parts are respectively positioned at two opposite sides of the base 110, so that the cleaning pump device 100 is reasonably distributed, and the space utilization rate on the base 110 is improved.

Specifically, referring to fig. 1, the base 110 is a plate-shaped structure, and the length × width × height thereof is: 350mm by 230mm by 410 mm. The diameter of the output shaft 121 of the motor 120 is 14mm, the power is 0.37KW, and in the using process, the two-phase alternating-current 0.75KW miniature generator 120 can be configured.

In one embodiment, referring to fig. 2, overflow pipe 151 is disposed on overflow valve 150. The overflow pipe 151 serves to press out the overflowing cleaning agent, so that when the flowing pressure in the overflow valve 150 is greater than the overflow pressure, the surplus cleaning agent is discharged through the overflow pipe 151.

Specifically, referring to fig. 3, the cleaning agent is an oily substance, one end of the overflow pipe 151 is also communicated with the oil tank 200, and when the oil pressure exceeds the overflow pressure, the cleaning oil automatically flows back to the oil tank 200 through the overflow pipe 151.

In one embodiment, referring to fig. 2, a pressure gauge 152 is disposed on the relief valve 150. The pressure gauge 152 is used for detecting the pressure in the overflow valve 150, so that the pressure in the overflow valve 150 is constantly monitored by the pressure gauge 152, and the flow condition in the overflow valve 150 is controlled in time.

In one embodiment, referring to fig. 3, the washing pump apparatus 100 further includes a filter screen 135. The filter screen 135 sets up in pump case 131, and the filter screen 135 is used for filtering the cleaner, so, through filter screen 135, filters the cleaner in the inflow system, guarantees that the cleaner is in clean, no miscellaneous state for the cleaner can be followed spray gun 300 middling pressure smoothly and go out, effectively avoids spray gun 300 to take place to block up.

In one embodiment, the motor 120 needs to be electrically connected to an external power source when it is activated. In the connection process, a control switch can be installed on the wire of the motor 120, and the start and stop of the motor 120 can be better controlled through the control switch.

In one embodiment, referring to fig. 2, the washing pump device 100 further includes a handle 122, and the handle 122 may be disposed on the motor 120 or the base 110. Thus, the handle 122 facilitates the operator to carry the washing pump device 100, thereby facilitating the improvement of the convenience of the washing operation.

In one embodiment, referring to fig. 3 and 5, an external locking switch cleaning system includes a spray gun 300, a fuel tank 200 and a cleaning pump device 100, wherein the spray gun 300 is communicated with one end of the control valve 140, the fuel tank 200 is communicated with the input port 132, and the fuel tank 200 is used for supplying cleaning oil to the power pump 130.

In the external locking turnout cleaning system, the cleaning pump device 100 is adopted, and in the cleaning process, the input port 132 on the pump shell 131 is communicated with the cleaning agent equipment; then, one end of the control valve 140 is communicated with one end of the spray gun 300 to complete the assembly of the cleaning system; then, the motor 120 is started to drive the movable plug 134 to reciprocate in the pump housing 131, so that the cleaning agent is sucked from the input port 132 and is pressed out from the output port 133 to the control valve 140; the control valve 140 is opened, so that the output port 133 is communicated with the spray gun 300, the cleaning agent in the control valve 140 is conveyed into the spray gun 300, the cleaning agent is sprayed onto the outer locking turnout part through the spray gun 300 by an operator, the outer locking turnout is kept clean, and the driving safety is ensured. Meanwhile, because the motor 120, the power pump 130 and the control valve 140 are all integrated on the base 110, when the outer locking turnout at different positions needs to be cleaned, an operator only needs to move the base 110 to realize the movement of the whole cleaning pump device 100, thereby greatly facilitating the cleaning operation of the outer locking turnout, reducing the mobility of the cleaning operation and improving the cleaning efficiency.

It should be noted that, the cleaning agent of this embodiment is cleaning oil, and in the cleaning process, the cleaning oil has two functions: firstly, cleaning up stains on the external locking turnout as a cleaning agent; and secondly, the lubricating oil is used as power oil, so that the lubricating oil can be prevented from being coated for lubrication, and the service life of hydraulic equipment cannot be influenced.
