Description

Portable grouting pump Technical Field The utility model relates to a portable grouting pump, and belongs to the technical field of grouting equipment. Background The grouting pump is a power device for conveying, adopts compressed oil or compressed air as a power source, and utilizes an oil cylinder or an air cylinder and a grouting cylinder to have larger action area ratio, so that the cylinder body can generate higher injection pressure with smaller pressure. Grouting pump equipment sold in the existing market is quite large, a trolley type grouting pump equipment is generally adopted, and otherwise, two people or even more people are required to move the grouting pump equipment. And searching the prior art, it can also be seen that the technical proposal disclosed in the prior art has a majority of road wheels in the structure, and the structure size and weight sold in the market are not greatly different. If CN201922124411.2 discloses a portable pneumatic grouting pump, adopts pneumatics, through the setting of lifter plate, can make the lifter plate place the below of grouting pump support, through the cooperation setting of motor and threaded rod, can make the lifter plate place different heights according to different grouting pumps in the use to play convenient to use's effect, reached the purpose that reduces artifical transport. As another example, CN201721697034.6 provides a portable grouting pump that is small in size, easy to maintain, and requires only one person to operate. The hydraulic pump has the structural principle that an oil cylinder quick connector 22 is connected with a high-pressure oil pipe of a drilling machine supporting oil cylinder, a pump head slurry suction port 5 is placed in configured cement slurry, a pump head slurry injection port 6 is connected with a drilling slurry injection pipe, the drilling machine is started, high-pressure oil firstly enters an oil cylinder body 2 from the oil cylinder quick connector 22 to push an oil cylinder piston 21 to move rightwards, and meanwhile, a connecting device 3 drives a pump head piston 4 to move rightwards, so that negative pressure is generated in the pump head cylinder body, a pump head steel ball 7 is tightly sucked on the pump head slurry suction port 5 and the pump head slurry injection port 6, and the pump head steel ball 7 cannot be completely sucked on the pump head slurry suction port 5 due to the fact that the pump head slurry suction port 5 is provided with a steel ball support frame 8, a certain gap is reserved between the pump head steel ball 7 and the pump head slurry suction port 5, and cement slurry enters the pump head through the gap. The front section of the grouting pump shell 1 is provided with a first supporting frame 11, and the rear section of the grouting pump shell 1 is provided with a second supporting frame 12.
