The present invention can adjust the conveying quality of the slurry and has the characteristics of high work efficiency, low cost and wide use range.
Description
Technical field
The invention belongs to the conveying device of slurry in the building operations, relate in particular to a kind of troweling machine.
Background technology
At building field, it is an important link that slurry is carried, and major part still adopts tower crane and derrick to carry out the conveying up and down of slurry at present, and this mode of movement floor space is big, construction is complicated, labor strength is big, and hidden danger is many, and human casualty accident happens occasionally.
Number of patent application provides a kind of slurry conveying device for 2003101056345 patent, it comprises double hydraulic cylinder and piston wherein, utilize the motion of piston to suck slurry, utilize hydraulic control system control hydraulic cylinder and slurry cylinder to realize the continuous conveying of slurry from charging aperture.The shortcoming of this slurry conveying device is that ash material conveying capacity is too big, and the output quantity of ash material can not be regulated according to actual needs.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective, the troweling machine that provides a kind of slurry output quantity to regulate.
For achieving the above object one of the present invention program: it comprises frame, and motor, hydraulic pump, hydraulic cylinder, slurry cylinder and feed hopper are installed on the frame, driven by motor hydraulic pump wherein, the slurry cylinder is communicated with feed hopper, and connects transfer pipeline, and the hydraulic pump of motor and drive thereof has two groups at least.
The hydraulic pump of motor and drive thereof can be that two motors drive two hydraulic pumps respectively, also can be that three motors drive three hydraulic pumps respectively.Wherein the power of three motors can be respectively 22 kilowatts, 11 kilowatts and 5.5 kilowatts, and corresponding hydraulic pump flow is respectively 125 milliliters/commentaries on classics, 65 milliliters/commentaries on classics and 32 milliliters/commentaries on classics; Corresponding therewith, internal diameter 80 millimeter of slurry transfer pipeline are good with 80 millimeters.Three motors connect pressure switch respectively, and this pressure switch is controlled by the pressure of transfer pipeline end, regulate the startup of motor and stop by pressure switch, thereby can realize the control of slurry output quantity.
Two of scheme is: it comprises frame, and motor, hydraulic pump, hydraulic cylinder, slurry cylinder and feed hopper are installed on the frame, driven by motor hydraulic pump wherein, and the slurry cylinder is communicated with feed hopper, and connects transfer pipeline, and motor has one, is frequency modulation motor.Its power can be 37 kilowatts, and corresponding with it have only a hydraulic pump, this hydraulic pump flow be 200 milliliters/change; Corresponding therewith, internal diameter 80 millimeter of slurry transfer pipeline are good with 80 millimeters.
The present invention adopts common electric machine or frequency modulation motor of three different capacities, by the control of work drive motor quantity or the change of frequency, and the output quantity that can regulate slurry, thus adapt to the field demand of building operations effectively.

The specific embodiment
Embodiment 1:
As shown in Figure 1, 2, present embodiment comprises frame, and motor, hydraulic pump, hydraulic cylinder 7, slurry cylinder 14 and feed hopper 10 are installed on frame, the driven by motor hydraulic pump, and the slurry cylinder is communicated with feed hopper, and is connected with transfer pipeline 11.Wherein motor adopts three motors 1,2,3 that power is different, and its power is respectively 22 kilowatts, 11 kilowatts and 5.5 kilowatts.Three motors drive three hydraulic pumps 4,5,6 respectively, its flow is respectively 125 milliliters/commentaries on classics, 65 milliliters/commentaries on classics and 32 milliliters/commentaries on classics, three motors connect pressure switch 14 respectively, this pressure switch is controlled by the pressure of transfer pipeline end, with the slurry transfer pipeline that above-mentioned motor and hydraulic pump are complementary, its internal diameter is good with 80 millimeters.
When slurry was exported, the structure that is connected with transfer pipeline was seen shown in Figure 4, and when work, transfer pipeline 11 connects flow divider 21; Two the bigger outlets in flow divider 21 two ends connect lateral transfer pipe 12 respectively, and two less outlets connect branch road 13 respectively in the middle of the flow divider; Lateral transfer pipe 12 connects two branch roads 13 respectively by threeway 22 again; Branch road 13 connects flexible pipe and exports slurry to terminal, and branch road 13 has six like this.By this structure, can change the slurry outgoing position as required at any time, practice of construction is convenient, high efficiency.
In real work,, just can export different hydraulic flows, thereby can reach different slurry output quantities by different motors of pressure switch switch and corresponding with it hydraulic pump.Its concrete mode: when motor 1,2,3 is worked simultaneously, can supply six roots of sensation efferent duct simultaneously and export out slurry; When motor 1,2 is worked simultaneously, can supply five efferent duct output slurries; When motor 1,3 is worked simultaneously, can supply four efferent duct output slurries; When motor 2,3 is worked simultaneously, can supply one or two efferent duct output slurries; When motor 3 works independently, can supply three efferent duct output slurries.
At preceding switch assembly place, see Fig. 2 in addition, the friction position of pricking plate up and down increases the high-abrasive material that can change, has increased the application life of this structure.
Also can in for the hydraulic oil container of hydraulic pump fuel feeding, heat sink be set simultaneously, its outlet is connected to the delivery port of brush vehicle water pump by water pipe, by the brush vehicle water pump water is transported to heat sink, has strengthened the cooling-down effect of fuel tank, and reduced the burden of the artificial water lift cooling of workman.
