Description
Technical field
The present invention relates to a kind of concrete pump, particularly relate to a kind of cast distributing valve concrete pump.
Background technology
Piston concrete pump is respectively provided with distributing valve, and it is the critical component in concrete pump, it is desirable to have 1, good suction, discharging performance；2, good transformational；3, the relative motion position of valve and valve body should have good sealing；4, there is good wearability；5, simple in construction is required, it is simple to processing.
Cast distributing valve is the most popular distributing valve of current concrete pump, and it is that the swing with pipe fitting is to reach the purpose that concrete sucks and discharges.Cast distributing valve is typically disposed in hopper, itself is a part for conveying pipe, and its one end is connected with conveying pipe, and the other end can swing.For single cylinder concrete pump, when the cast distributing valve mouth of pipe puts away concrete cylinder mouth and sealed by bucket wall, concrete cylinder carries out suction；When the cast distributing valve mouth of pipe swings back alignment concrete cylinder mouth, concrete cylinder carries out discharge.For twin-tub concrete pump, then the cast distributing valve mouth of pipe and two concrete cylinder mouths are alternately connected, and are directed at which cylinder mouth, and which cylinder mouth just carries out discharge, and another cylinder mouth just carries out suction simultaneously.
S type that what cast distributing valve was conventional comprise, C type and skirt type (similar mini-skirt profile and gain the name), such as Fig. 1 a-1d.For the most frequently used S bend pipe type distributing valve, as illustrated in figures 2 a-2b: it is internal that S bend pipe type distributing valve 10 is placed in hopper 2, the interface of S bend pipe type distributing valve 10 and concrete cylinder 3 is on the rear wall plate 20 of hopper 2, the end opening of cast distributing valve 10 swings under the effect of oil cylinder 4, alternately dock with two concrete cylinders 3 and pump, the concrete cylinder then discharge connected, the concrete cylinder of access failure is with regard to charging.Its advantage is: 1, good transformational；2, the relative motion position of valve and valve body should have good sealing (shape of pipe is conducive to the seal groove accurate by lathe process)；3, there is good wearability；5, simple in construction, it is simple to processing (skirt valve no this item advantage).Shortcoming is: to enter concrete cylinder to the material sunk, it is necessary to occurring the flowing of 90 degree to alter course, so hopper gathering materials property difference, the concrete that slump of collapsing is little, the concrete that building stones are bigger, pump highly difficult, high density solid material and high viscosity pug are just more difficult.
At present that the little concrete of slump of collapsing or building stones is bigger concrete, is generally adopted inclined type flashboard distributing valve.As shown in Figure 3 a-3b: arrange with the angle of more than 60 degree left and right between flashboard distributing valve 11 and concrete cylinder 3, there is two-position three way function, the flashboard 110 being made flashboard distributing valve 11 by oil cylinder 4 moves up and down, control the path of concrete cylinder 3 and hopper 2 and conveying pipe 5, carry pipe 5, piston 6 rearward movement to make concrete be in from hopper 2 feed state when flashboard 110 goes down to enclose；When flashboard 110 is mentioned by oil cylinder 4, then enclose the discharging opening of hopper 2, simultaneously piston 6 and travel forward, make concrete cylinder 3 be in discharge state.Twin-tub concrete pump adopts two set inclined type flashboard distributing valve, alternately reciprocating action, continuously pump concretes.Its advantage is: 1, good suction, discharging performance；2, good transformational；3, there is good wearability.Shortcoming is: 1, the relative motion position sealing of valve and valve body is poor, causes that fed distance is short, the cleaning pump line difficulty after the end of job；2, structure is complicated, not easily processes, not easily maintains.
Blender concrete pump is stirring for the combined integrated machine of machine and concrete pump, this equipment is mainly used in the engineering construction of small building, Site, owing to these engineering construction scenes disperse, stone source is various and consumption is few, not as the easy like that specification Stone Standard Value of the mixing plant of batch production, large-scale production and buying, therefore, objectively require that building stones to be had higher adaptability by the concrete pump hopper supporting with it and distributing valve, it is especially desirable to bigger stone, less slump of collapsing can be pumped.The patent " flashboard type blender concrete pump " of CN201220553405.4 discloses the use of flashboard type distributing valve to solve the pumping of stone specification not easily occasion up to standard, but sealing is poor to be also faced with the defect of flashboard type distributing valve-----, causes that fed distance is short.
Concrete pump application in industrial circle is exactly high density solid pump, as shown in Figure 4, and mud in power plant and turf pump used by the mixed burning of waste coal；Sewage treatment plant's mechanical dehydration sludge pumping and refuse process the high density solid pump in conveying；In mine surface and underground, the high density solid pump of flotation waste material and mine tailing, mining and backfill conveying；The silt delivery pump of water body desilting top layer silt or silt, these pumps all have employed same cast distributing valve principle and structure, in order to allow high density solid better suck conveying cylinder, also to ensure longer fed distance simultaneously, so be mounted with a screw feeding device 7 on hopper top, in the way of forcing pressurization, distributing valve is helped to improve suction efficiency.This not only proves that the imbedibility of cast distributing valve needs to improve, and namely the increase of screw feeding device simultaneously adds cost, adds again the space of equipment volume and needs, is unfavorable for promoting the use.
Same cast distributing valve principle, for the removed-earth jet sowing machine (also referred to as wet-spraying machine) of greening side slope, due to the highly viscous resistance of clay, suction material property is also poor.Also face sand naturally sink in time for the tubular type mortar pump of metope mortar, spray pump, shelter from charging aperture, there is the difficult problem affecting suction material property.
