Abstract

The utility model provides a device for quickly disassembling and assembling piston, which cancels the traditional piston connector which directly connects the flange of the piston rod with the concrete piston. A sink is provided with a limit bracket which is sleeved on the piston rod so as to limit the movement of the concrete piston and avoid bumping cylinder. By removing the limit bracket, the utility model can conveniently pull the concrete piston to the sink so as to expose the concrete piston and the connected flange in the sink. By the structure, the abrasion of the concrete piston can be checked, and disassembling and assembling as well as maintaining are more convenient. The utility model has advantages of greatly saving time and remarkably prolonging service life of the concrete piston, thereby being a very practical reforming device.

Description

A kind of device of being convenient to the fast assembling-disassembling piston

This practicality relates to the piston connection device in a kind of concrete pump pumping system, especially a kind of device of being convenient to the fast assembling-disassembling piston.

At present, the pumping system of traditional concrete pump, in Fig. 3, pumping master cylinder (9) is connected with concrete piston (2), all be that a end by piston connector (10) is connected with the flange (5) of piston rod, the other end is connected with concrete piston (2), this jockey is when dismounting and installation concrete piston (2), need quite complicated step, expend a large amount of time, this brings great inconvenience for the Operation and maintenance personnel in use in the building site, and when not pulling down piston connector (10), can't check the wearing and tearing of concrete piston (2); In addition, this Unit Installation also can increase the same axis error of master cylinder (9) and concrete piston cylinder (2-1), adds galling; " hitting cylinder " phenomenon of main shaft oil cylinder (9) also easily takes place during malfunctioning switch.

The utility model proposes a kind of device of being convenient to the fast assembling-disassembling piston, its dismounting is simply easy, can save the plenty of time, can check the concrete wearing for piston at any time, and " hitting cylinder " phenomenon can not take place its axiality height.

The purpose of this utility model is achieved in that it is piston connector (10) complete removal, the flange (5) of piston rod (6) directly is connected with concrete piston (2), go up an installation limiting bracket (7) at piston rod (6), with it concrete piston (2) and main shaft oil cylinder (9) are kept apart, can effectively prevent to hit the generation of cylinder phenomenon.

Owing to adopted such scheme, can make concrete piston (2) easy disassembling, a large amount of dismounting time can be saved, and the abrasion condition of concrete piston (2) can be checked at any time, its axiality height can prolong service life of concrete piston (2), also can not hit the cylinder phenomenon.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 is a structure principle chart of the present utility model;

Fig. 2 is for after the utility model takes away limiting bracket, and concrete piston and adpting flange are exposed to the view in the tank;

Fig. 3 is piston connector (10) and concrete piston (2) and piston rod (6) syndeton schematic diagram;

Fig. 4 is the front view (left figure) of limiting bracket and the structural representation of side view (right figure).

Among the figure, 1. concrete piston/cylinder 2. concrete piston 2-1.

In Fig. 4, left side figure is the front view of limiting bracket (7), right figure is the side view of limiting bracket (7), the bottom of limiting bracket (7) is the round frame (7-3) of a lower aperture, opening is greater than the diameter of piston rod, its middle part is link (7-2), its top is the support grillage (7-1) of a spill, supporting coincide corresponding with tank (8) of grillage (7-1) installs, cover rides over the both sides of piston rod, as shown in Figure 1, can limit the scope of activities of concrete piston (2), can avoid concrete piston (2) to hit cylinder; Take away limiting bracket (7), concrete piston (2) is moved in the tank (8), as shown in Figure 2, one can check the degree of wear of concrete piston (2), two can easy disassembly, maintenance, can save maintenance time greatly.
