Next, a concrete product installation apparatus according to one embodiment of the present invention will be described with reference to FIGS.
Lifts and slide hydraulic cylinders 1, 1 that can be moved up and down, left and right, and back and forth one by one so that they can support concrete products, for example, box culverts 23.
8 is provided on the frame body, and the frame body is integrally connected with the joint member 22 in a substantially U-shape when viewed from above.

Here, a specific embodiment of the installation device 24 will be described in detail. The traveling wheel 4 made of urethane is provided on the wheel support member 25 so as to be driven by the drive reduction gear 5 and the drive hydraulic motor 6 via the chain 19. The lift hydraulic cylinder 1 is provided on the upper part of the wheel support member 25. The lift hydraulic cylinder 1 has a mounting plate 2 as a support member for supporting the box culvert 23 as a concrete product.
And the set bolt 3, and the box culvert 23 is held by the mounting plate 2 and the set bolt 3.

Further, the wheel support member 25 is provided with a slide hydraulic cylinder 18 as shown in the drawing, which is capable of moving left and right with respect to a support member including the mounting plate 2 and the set bolt 3. Reference numeral 7 denotes an auxiliary wheel.

Each operation lever is provided at an appropriate position of the joint member 22 connecting the installation devices. It is for example: 10 is a left, back (front) lift operation lever, 11 is a left, front lift operation lever, 12 is a left,
Drive operation lever, 13 is right, drive operation lever, 14 is right, front lift operation lever, 15 is right, back (front) lift operation lever, 16 is left, slide operation lever, 17 is right, slide operation lever .

Then, the diesel engine 20 is operated by the fuel of the light oil tank 8 for operating the lift hydraulic cylinder 1 and the slide hydraulic cylinder 18, and the oil of the hydraulic oil tank 21 is pumped by the hydraulic pump 9. The lift and slide hydraulic cylinders 1 and 18 are driven by the operation lever.

Further, as shown in FIG. 8, the width of the installation device can be changed using the joint material 22 so as to cope with a change in the size of the concrete product as an embodiment. That is, a number of positioning holes 26 are formed in the joint member 22, and the width is determined by selecting the positioning holes 26 and fixing them with bolts and nuts.

Next, one embodiment of the actual installation method will be described. (1) The foundation is cast in place. Overhang 50cm or more from the entire width of the concrete product (the strength of the foundation must be strong enough to run the installation device). (2) There are four inserts or mounting holes on the side of the concrete product. (3) Hang the concrete product on the foundation with a truck crane or the like. (4) The installation device can operate all of the power of the engine. The engine uses a self-starter-equipped engine. The starter is inserted and the engine is started. For traveling (driving), a hydraulic motor for driving, lift-up and left / right slide are operated by hydraulic cylinders, and are operated by respective operation levers. (5) The left and right traveling (driving) operation levers are moved forward by pushing forward. Move the installation device to a position where the concrete product can be fastened to the mounting plate with the set bolt. The height position of the set bolt hole is adjusted by the lift operation lever and moved up and down to a position where the bolt can be set. (6) Move the gap between the concrete product and the mounting plate with the left and right slide operation lever until it is in close contact, and lightly tighten the set bolt. (7) Raise the lift with the lift operation levers (4 front / rear, left / right), lift up until the lower surface of the set bolt hits the lower side of the upper and lower slots formed in the mounting plate, and securely tighten the bolt to complete the preparation. . (8) Simultaneously operate four lift operation levers to lift up the concrete product. Check that the concrete product has completely lifted from the foundation. (9) The left and right drive operation levers are simultaneously operated to move forward. The direction of travel can be corrected by stopping or retracting one of the drive operation levers. (10) Move to a position just before the joint with the previously installed concrete product. Since there is a height difference of about 50 to 70 mm between the concrete product installed before and the concrete product which is transported next, the concrete product is gradually lowered with the lift operation levers (four). (11) If the left and right positions are deviated, the left and right slide operation levers are operated in the same direction to adjust the left and right positions, and the joint is moved down and forward. (12) Since the four lift operation levers are independent of the front, rear, left and right, when it is difficult to joint, it is preferable to move the lift only up or down only at the front or only at the rear. (13) The rotational speed of the operation can be adjusted by an engine throttle lever (not shown). (14) After installation at a predetermined position, remove the four set bolts and move the mounting plate outward with the left and right slide operation levers. (15) Retract with the drive operation lever, and start transporting and installing the next concrete product. It will be installed by repeating the above. By adjusting the positioning holes of the joint material, it is possible to cope with concrete products of all sizes.

A method of continuously moving the concrete product to the right or left will be described with reference to FIGS. The case of moving to the right will be described as an example. (1) Slide the concrete product all the way to the right with the slide operation lever. (2) Lower the concrete product with the lift operation lever and continue operating the installation device itself until it floats in the air. (3) Slide the installation device all the way to the left with the slide operation lever. (4) The concrete product is lifted up by the lift operation lever. The horizontal movement can be performed by repeating the above (1) to (4).

[0021]

According to the present invention, as a result of employing the above configuration,
The following effects can be obtained. (1) No need to lay rails, etc., and transport can be performed freely. (2) Since fine adjustment in up, down, left, right, front and back is possible, accurate installation is possible. The construction can be performed safely without requiring a large amount of labor.
