Embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1:
As shown in Figure 1, the utility model embodiment's the concrete pump set with approach switch is mainly by carrying cylinder 1, concrete piston 2, water tank 3, concrete piston adpting flange 4, clip 5, master cylinder front cover 6, main oil cylinder piston bar 7, rod chamber hydraulic fluid port 8, rod chamber 9, master cylinder 10, repairing pipe 11, main oil cylinder piston 12, rodless cavity mouth 13, sleeve 14, approach switch 15, flange 16 to form;
Concrete piston 2 dresses are arranged on to be carried in cylinder 1, carry cylinder 1 to connect water tank 3 by flange 16, water tank 3 is arranged on the outside of concrete piston 2, master cylinder 10 is arranged on the rear end of carrying cylinder 1, master cylinder front cover 6 is arranged on the front end of master cylinder 10, main oil cylinder piston bar 7 is arranged on the inside of master cylinder 10, clip 5 is arranged on the top of main oil cylinder piston bar 7, clip 5 is by concrete piston adpting flange 4 connecting concrete pistons 2, rod chamber hydraulic fluid port 8 is arranged on the offside of master cylinder front cover 6, rod chamber 9 be arranged on main oil cylinder piston bar 7 a side, repairing pipe 11 is arranged on master cylinder 10, main oil cylinder piston 12 is arranged on the inside of master cylinder 10, and be connected with main oil cylinder piston bar 7 by sleeve 14, rodless cavity mouth 13 is arranged on the end of master cylinder 10, approach switch 15 is arranged on the correct position of master cylinder 10.
Fill a flange 16 that concrete piston 2 is fallen back on to 3 position-limiting actions of water tank at water tank 3 with a side of carrying cylinder 1 to be connected, the effect of flange 16 is the protective actions that rise in the time of electrical signal loss signal, while preventing work concrete pour out produce danger, approach switch is arranged on the appropriate location of master cylinder;
Working principle of the present utility model:
When the utility model working state, press play button, main oil cylinder piston 12 is during near approach switch 15, and approach switch 15 sends signal, and selector valve commutation, changes the direction that main oil cylinder piston 5 moves, and completes normal pumping; While moving back piston mode, press and move back piston button (comprising that Dan Shuan moves back), main oil cylinder piston 12 is during near approach switch 15, and approach switch 15 sends signal, and selector valve does not commutate, and the direction that main oil cylinder piston 12 moves is constant, continues to retreat;
Master cylinder 10 is in the time stretching out, in the time that sleeve 14 enters the master cylinder front cover 6 with damping hole, the gap that fluid between sleeve 14 and master cylinder front cover 6 can only form from both, be extruded, sleeve 14 will be subject to a back pressure effect very large, that set up by gap throttling, thus the buffering of realization;
When concrete piston 2 in conveying cylinder 1 falls back on water tank 3 position, complete and change concrete piston 2, while having changed concrete piston 2, press reset button, main oil cylinder piston 12 advances to approach switch 15 places, can carry out normal pumping work by play button again, by connecting signal that the signal processor of approach switch 15 provides, to make to move back piston be that Dan Shuan moves back piston and switches arbitrarily.
The above is only to preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, every foundation technical spirit of the present utility model is to any simple modification made for any of the above embodiments, equivalent variations and modification, all belong in the scope of technical solutions of the utility model.
