Abstract

The utility model discloses a concrete pumping hydraulic device, which comprises a cylinder A with a cavity a1 and a cavity a2, a cylinder B with a cavity b1 and a cavity b2, a manual reversing valve and a connecting plate. The manual reversing valve is a two-station four-way manual reversing valve, the connecting plate is provided with four oil channel through holes which are respectively communicated with the cavity a1 and the cavity a2 of the cylinder A and the cavity b1 and the cavity b2 of the cylinder B, the two stations of the reversing valve are a high-pressure station and a low-pressure station, wherein the high-pressure station is connected with the cavity b1 of the cylinder B through one path of the connecting plate and is also connected with the cavity a1 of the cylinder A through one path of the connecting plate; and the low-pressure station is connected with the cavity b2 of the cylinder B through one path of the connecting plate and is also connected with the cavity a2 of the cylinder A through one path of the connecting plate. With the manual reversing valve instead of the original valve body and valve cover, only the handle of the reversing valve is required to be pulled during the conversion of the high-pressure station and the low-pressure station. The utility model has the advantages of simple structure and convenient assembly, disassembly and use, and significantly saves the time of the user.

Description

The concrete pumping hydraulic pressure installation

Technical field

The utility model relates to a kind of concrete pumping hydraulic pressure installation, particularly a kind of concrete pumping hydraulic pressure installation that adopts hand-operated direction valve.

Background technique

Available coagulation soil pumps hydraulic device, form by two oil cylinders, two selector valves, a connecting plate, two selector valves are installed in two oil cylinder afterbodys respectively and are connected by connecting plate, the valve body of two selector valves adopts bolt to be connected with valve gap, all bolts must be pulled down when commutating if desired valve gap is rotated moving 90 degree, bolt on after the commutation of realization oil duct, therefore commutation bothers very much again.

The model utility content

The purpose of this utility model is to provide a kind of loading and unloading quick, easy to use and oil tight concrete pumping hydraulic pressure installation.

This concrete pumping hydraulic pressure installation that the utility model provides, comprise the A oil cylinder with a1 chamber and a2 chamber, B oil cylinder, hand-operated direction valve and connecting plate with b1 chamber and b2 chamber, described hand-operated direction valve is a two-position four-way hand-operated direction valve, described connecting plate has four oil circuit through holes to be communicated with a1 chamber, the a2 chamber of A oil cylinder respectively, be communicated with b1 chamber, the b2 chamber of B oil cylinder, two of described selector valve is high pressure position and low pressure position, its mesohigh position is by the b1 chamber of connecting plate one tunnel connection B oil cylinder, and one the tunnel connects the a1 chamber of A oil cylinder; The low pressure position is by the b2 chamber of connecting plate one tunnel connection B oil cylinder, and one the tunnel connects the a2 chamber of A oil cylinder.

The high pressure position of described hand-operated direction valve is crossed oiled-plate method 3 by one respectively with the low pressure position and is connected with the b2 chamber of B oil cylinder, is connected with the a2 chamber of A oil cylinder.

The described oiled-plate method 3 of crossing is fixed on the connecting plate, and hand-operated direction valve is installed in two and crosses on the oiled-plate method 3, and they all are positioned at an end of A oil cylinder and B oil cylinder.

This new concrete pumping hydraulic pressure installation that the utility model provides adopts a hand-operated direction valve to replace original valve body and valve gap, and the handle that only need spur selector valve when carrying out the high low pressure conversion gets final product.Of the present utility modelly not only structurally become simple by complexity, its loading and unloading, use also convenient, the time of having saved the user greatly.

Embodiment

From Fig. 1 to Fig. 2 as can be seen, this concrete pumping hydraulic pressure installation that the utility model provides, comprise two A oil cylinders of laying side by side and B oil cylinder, a hand-operated direction valve 1 and the connecting plate 2 that two-position four-way is manual, the rod chamber of this A oil cylinder is the a1 chamber, rodless cavity is the a2 chamber, the rod chamber of B oil cylinder is the b1 chamber, rodless cavity is the b2 chamber, also be connected with an oiled-plate method 3 excessively respectively in the outside in A oil cylinder a2 chamber and the outside in B oil cylinder b2 chamber, crossing oiled-plate method 3 is fixed on the connecting plate 2, hand-operated direction valve 1 is installed in two and crosses on the oiled-plate method 3, and two of this hand-operated direction valve 1 is high pressure position and low pressure position, and this connecting plate 2 has four and the corresponding oil circuit through hole of hand-operated direction valve 1 four-way, its respectively with the a1 chamber of A oil cylinder, the a2 chamber is communicated with, with the b1 chamber of B oil cylinder, the b2 chamber is communicated with.

As can be seen from Figure 3, when hand-operated direction valve 1 is in the low pressure position, whole oil circuit is in low-pressure state, pressure oil enters from the P mouth of hand-operated direction valve 1, through hand-operated direction valve 1 a right B2 mouth, and connecting plate 2 enters the b1 chamber of B oil cylinder, pass through oiled-plate method 3, connecting plate 2 again from the b2 chamber and entered hand-operated direction valve 1 left side B1 mouth, flow out through connecting plate 2, cross the a2 chamber that oiled-plate method 3 enters another A oil cylinder from 1 right A2 mouth of hand-operated direction valve, enter hand-operated direction valve 1 left side A1 mouth by the a1 chamber through connecting plate 2 at last and flow out, realize operating on low voltage from the T mouth.

As can be seen from Figure 4, when hand-operated direction valve 1 is in the high pressure position, whole oil circuit is in high pressure conditions, pressure oil enters from the P mouth of hand-operated direction valve 1, through hand-operated direction valve 1 left side B1 mouth, and connecting plate 2, cross the b2 chamber that oiled-plate method 3 enters the B oil cylinder, enter hand-operated direction valve 1 a right B2 mouth from the b1 chamber through connecting plate 2 again, flow out the a1 chamber that enters the A oil cylinder through connecting plate 2 from hand-operated direction valve 1 left side A1 mouth, enter hand-operated direction valve 1 a right A2 mouth by the a2 chamber through oiled-plate method 3, connecting plate 2 at last and flow out, realize high-pressure work from the T mouth.
