Description

Movable gear pump Technical Field The utility model relates to the technical field of gear pumps, in particular to a movable gear pump. Background Gear pumps are rotary pumps that rely on the change and movement of working volume created between a pump cylinder and an intermeshing gear to deliver or pressurize a liquid. The gear pump consists of two gears, a pump body and a front cover and a rear cover, when the gears rotate, the volume of the space at the disengaging side of the gears is changed from small to large, vacuum is formed, liquid is sucked in, the volume of the space at the engaging side of the gears is changed from large to small, and the liquid is extruded into a pipeline. The suction chamber is separated from the discharge chamber by the meshing line of the two gears. The pressure at the discharge of the gear pump is entirely dependent on the amount of resistance at the pump outlet. At present, the Chinese patent with the application number of CN202022168041.5 on the market discloses a movable gear pump which comprises a motor and comprises a base plate, a gear pump housing, a driving shaft, a driving gear, a driven shaft, a driven gear, a liquid inlet, a mounting sleeve, a liquid inlet pipe, a filter screen, a liquid outlet pipe and universal rollers, wherein the gear pump housing is a hollow cavity, the gear pump housing is fixed on the base plate, the driving shaft penetrates through the gear pump housing, two ends of the driving shaft are rotationally connected with the gear pump housing and are connected with the motor, the driving gear is embedded in the gear pump housing, the driving gear is sleeved on the outer side of the driving shaft and is not relatively rotated with the driving shaft, the driven shaft is embedded in the gear pump housing, two ends of the driven shaft are rotationally connected with the gear housing and are positioned above the driving shaft, the driven gear is sleeved on the outer side of the driven shaft, the driven gear and the driven shaft is not relatively rotated, and the driven gear is meshed with the driving gear. In the prior art, the device can move in any direction through the four universal rollers arranged at the bottom end of the bottom plate, but the structure for replacing the universal rollers below the bottom plate is not specifically disclosed, the universal rollers are arranged on the bottom plate in a common installation mode mostly through bolt connection, and when the universal rollers are worn and damaged to be replaced, the universal rollers are arranged at the bottom end of the bottom plate, so that the device needs to be laid down to detach the bolts to replace the universal rollers, and the universal rollers are inconvenient to replace. Disclosure of Invention Aiming at the technical defects, the utility model aims to provide a movable gear pump which has the advantage of being convenient for replacing universal rollers. In order to solve the technical problems, the utility model adopts the following technical scheme: The utility model provides a movable gear pump, which comprises a bottom plate arranged below the gear pump, wherein four corners of the bottom end of the bottom plate are respectively provided with a communication groove, mounting columns are detachably mounted in the four communication grooves through mounting pieces, and universal idler wheels are mounted at the bottom ends of the four mounting columns through first bolts.
