Problems solved by technology

[0004] In the process of realizing the present invention, the inventor found that in the existing concrete delivery pump, when the concrete piston needs to be repaired, there are many steps to disassemble the concrete piston, the disassembly process is complicated, it takes a long time, and the disassembly labor intensity is high; at the same time If the concrete piston is disassembled during the construction process, the concrete is easy to solidify and block the conveying pipeline during the dismantling process for a long time, which will affect the construction effect of the concrete conveying pump

Abstract

The invention discloses a concrete transfer pump comprising a main oil cylinder, a concrete cylinder and a water tank arranged between the main oil cylinder and the concrete cylinder; the main oil cylinder is internally provided with a main piston connected with a concrete piston arranged in the concrete cylinder through a main piston rod, and the main piston drives the concrete piston to do reciprocating motion under the action of hydraulic oil in the main oil cylinder; the end part of the main oil cylinder is also provided with a multi-stage oil cylinder which limits the motion stroke of the main piston by a way of supporting against the main piston; and the motion stroke of the main piston is shifted between a working stroke and a dismantling stroke through the protrusion or retraction of the multi-stage oil cylinder. In the embodiment, when the concrete piston of the concrete transfer pump is maintained, the concrete piston can be directly withdrawn to the water tank through retracting the multi-stage oil cylinder so as to be dismantled with simple process and short time; meanwhile, the concrete transfer pump has compact whole structure and small size.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of concrete delivery, and in particular to a concrete delivery pump. Background technique [0002] When the concrete delivery pump is working, the concrete piston needs to reciprocate in the concrete cylinder to press the concrete into the delivery pipeline. Therefore, the concrete piston is a key component in the concrete delivery pump. At the same time, because it needs to be in direct contact with the concrete, the concrete piston It is also a vulnerable part that requires frequent disassembly and maintenance. [0003] figure 1 It is a structural schematic diagram of an existing concrete delivery pump. Such as figure 1 As shown, in the existing concrete delivery pump, the concrete piston 10 and the main piston rod 11 are connected by a detachable connecting rod 12. During normal operation, the main piston rod 11 can pass through the main cylinder 13 under the action of hydraulic o...
