And are detachably connected by hydraulic piping.

Since both the pump section and the prime mover section are installed on the mini-trailer, they can be towed to the operating site by a towing vehicle and transported, and can be moved in the same manner as a normal concrete pump vehicle. At the site, it can be made stationary immediately by removing the towing vehicle. Furthermore, since the pump section has outriggers on both front and rear sides, thrust when the viscous fluid pump is operating can be maintained.

Further, the crane is mounted on the mini-trailer of the pump section, so that the work for mounting the components of the viscous fluid pump on the mini-trailer can be performed by using the simple crane.

Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 to 4 show an embodiment of the present invention. Instead of the bases 9 and 25 fixedly installed on the ground with anchor bolts 32 shown in FIGS. Small trailers (mini-trailers) 33 and 34 having wheels 35 and supporting legs 36 attached to the front side so that they can be undulated are used, and the pump section I shown in FIG.
6 is mounted on the mini-trailer 34 so that the discharge side of the swing valve 7 faces forward.
(A) A prime mover section II similar to the prime mover section II shown in (b),
The hydraulic pipe connecting portion 31 is mounted so as to be positioned forward, and the hydraulic pipe relay portion 37 is mounted on the front side of the prime mover portion II, and one end side of the flow path 38 for each hydraulic pipe in the relay portion 37 is mounted. And the hydraulic pipe connection portion 31 are connected by hydraulic pipes 39, respectively, and the other end side of the flow path 38 in the relay portion 37 and the supply / discharge portions 15 and 16 of the pump portion I and the pressure accumulator 11 are connected. The spaces are connected by hydraulic pipes 40 with one-touch couplers at both ends so that they can be attached and detached by one-touch system.

Further, as shown in FIG. 2, on the mini-trailer 33 on which the pump section I is installed, outriggers 41 and 42 are attached to the front end and the rear end so that they can be expanded and contracted in the horizontal and vertical directions. , A small size in which a trolley 47 is movably supported by a girder 46 which can be moved in the left-right direction along a rail 45 on a gate-shaped leg 44 which is installed as a crane 43 on the mini-trailer 33 with a required interval in the front-rear direction. As the crane 48, a small one in which the trolley 47 is supported so as to be movable in the left and right direction is installed on the horizontal portion of the gate frame 49 installed so as to straddle the swing valve 7, and the viscous fluid pump is installed. It should be used when installing each component device.

Reference numeral 50 is a connecting member at the front ends of the mini-trailers 33 and 34 when the pump unit I and the prime mover unit II are transported to the operation site.

Now, when the viscous fluid pump device of the present invention, which is independent of the pump section I and the prime mover section II, is transported to the installation position near the construction site which is the operation site, the pump section I
The mini-trailer 33 and the mini-trailer 34 of the prime mover section II are separately connected to the towing vehicle and transported by the towing vehicle.
When the pump section I and the prime mover section II are transported to the operation site,
The towing vehicle is removed from the mini-trailers 33 and 34, and the support legs 36 of the mini-trailers 33 and 34 are stood up and stably placed. At this time, as shown in FIG. 1, the rear end side of the mini-trailer 33 on which the pump unit I is mounted and the front end side of the mini-trailer 34 on which the prime mover unit II is mounted are placed close to each other.

Next, the supply / discharge parts 15 and 16 of the pump part I and the pressure accumulator 11 and the relay part 37 on the side of the prime mover part II are connected by a hydraulic pipe 40 having a one-touch coupler at both ends, and the prime mover part II is connected. By the operation of the main oil pump 21, the pressure oil is supplied to the penetrating cylinder 4, the main cylinder 5 and the pressure accumulator 11 of the pump unit I, and at the same time, the return oil is returned to the oil tank 23 of the engine unit II.

Further, in order to further stabilize the pump portion I, the front and rear outriggers 41 and 42 are extended and grounded to stabilize the mini-trailer 33.

On the discharge side of the oscillating pipe 6, a transport pipe mounted on the mini-trailer 33 of the pump unit I is connected, and the transport pipes are sequentially added to transport the viscous fluid to a desired location. It can be so.

When the preparation is completed as described above, the main electric motor 19 of the prime mover section II is driven to operate the main oil pump 21, and the oil from the oil tank 23 is sent to the pump section I to operate the viscous fluid pump. The viscous fluid in the hopper 1 is pumped through the swing pipe 6 through the transport pipe. At this time, in the pump part I, the vibrating fluid may be largely shaken due to thrust or the like associated with suction and discharge, but the outriggers 41 and 42 provided in the mini-trailer 33 can suppress the movement of the mini-trailer 33, and the stationary type can be used. There is no trouble.

Depending on the progress of on-site work, the pump unit I
And it may be necessary to move the installation position of the prime mover section II. In such a case, in the pump section I, the outriggers 41 and 42 can be slightly shortened to be easily moved to an arbitrary position by the mini-trailer 33, and the prime mover section II can also be easily moved by the mini-trailer 34. Therefore, it is possible to enhance the mobility even though it is a stationary type, and it is possible to save labor in the relocation work.

Further, in the viscous fluid pump device of the present invention, since the small cranes 43 and 48 are equipped on the pump section I side, mounting and assembling of the components of the viscous fluid pump on the mini-trailer 33, etc. Small crane 43,
48 can be used and workability can be improved.

The penetration type viscous fluid pump of the pump section I is shown, but the viscous fluid pump may be of another type, and the prime mover section II is also an example, and is not shown. In addition, the small crane 43 is an example, and it is sufficient that the trolley 47 can move back and forth and left and right. For example, a gate arranged so as to straddle a viscous fluid pump. Needless to say, the mold frame may be allowed to travel in the front-rear direction on the mini-trailer 33, and various changes may be made without departing from the scope of the present invention.

[0022]

As described above, according to the stationary viscous fluid pump device of the present invention, the pump portion and the prime mover portion, which have independent structures, have wheels for traveling and support legs for installation, and Separately installed on different mini-trailers that have a connector to the towing vehicle, and attached outriggers to the front and rear sides of the mini-trailer that installs the pump section. Since the viscous fluid pump is a stationary viscous fluid pump, it can be easily moved, mobility can be improved, and labor for changing the location for stationary can be saved. Also, since the mini-trailer on which the pump section is installed is equipped with an outrigger, it is possible to hold thrust when the pump is operating and to function as a stationary type. By equipping the lane, the handling of the devices in the assembly or the like of the viscous fluid pump can be enhanced workability eased, an excellent effect like.
