Description

[Detailed Description of the Invention] When moving a bridge, the follower uses ball bearings to move the bridge.
It was mounted on a roller, etc., and pulled and moved using a winch, etc.

In addition, a front and rear fixing device that supports and fixes both ends of a frame body on which a heavy object such as a bridge is mounted, a lifting mechanism drive device incorporated in the both fixing devices, a front and rear sliding cradle, A moving device with a front sliding cradle that functions to move the entire diamond road, heavy objects, and the aforementioned front sliding cradle by a fixed amount, and a rear sliding holder for moving the rear sliding cradle by a fixed amount at a time. BACKGROUND ART A device for moving large heavy objects such as a bridge, which is composed of various devices such as a moving device with a platform, is well known. (For example, Samurai Seki 48-9862
(See Publication No. 8). The former has problems with the stability of the bridge during movement, as well as poor workability as it requires changing the position of rollers, etc., while the latter requires the entire device to be a combination of several devices. If any one device breaks down, it will take time to find the fault, making it difficult to expect a quick repair, and the entire device will become larger. have. The present invention has been made by focusing on such well-known moving construction methods and moving straight lines, and is a simple method constructed by associating a small number of main components such as a machine frame, a transfer jack, a bed plate, and a push-up jack. Regarding the moving device of the structure, it is possible to move the bridge stably and reliably one step at a time, and
To provide a moving device for a bridge, etc., which can be moved safely and quickly and can be repaired immediately even if a failure occurs.

An example of implementation of the present invention will be described.

The machine frame 1 is assembled and molded from H-shaped steel or wedge-shaped steel so that it has a mouth-shaped cross section, and a transfer jack A is installed on one side, so that it can be moved freely in the machine frame 1. A rail 5 is provided on the upper edge of the machine frame 1 so that the feed shaft 3 of the transfer jack A is inserted into the frame 1, and the base plate 2 on which the push-up jack B is fixedly installed is reciprocated along the rail 5. Mount it so that it can slide freely.

The base plate 2 that slides back and forth on the upper surface of the machine frame 1 is connected to the rail 5 of the machine frame 1.
The push-up jack B is erected and fixed on the base plate 2 so that the push-up shaft 4 of the push-up jack B can move up and down in the vertical direction, and the connecting piece 6 is suspended from the bottom of the base plate 2, The feed shaft 3 of the transfer jack A is connected via the connecting shaft 7.
The base plate 2 reciprocates on the machine frame 1 by moving the feed shaft 3 in and out.

The transfer jack A has a cylinder 8 disposed on an extension in the lateral center direction from one side of the machine frame 1, which is fixed to one side of the machine frame 1, and a feed shaft 3 protruding from the cylinder 8. is inserted into the machine frame 1, its tip is connected to the connecting piece 6 of the base plate 2 via the connecting shaft 7, and the feed shaft 3 is moved in and out of the cylinder 8 by hydraulic operation of the movable jack A. The inside of the frame 1 is moved repeatedly to cause the platform 2 to reciprocate and slide along the top of the machine frame 1.

The push-up jack B is erected and fixed on the base plate 2, which moves back and forth on the machine frame 1, so that the push-up shaft 4 of the push-up jack B moves up and down in the vertical direction. A support plate 9 is attached to the tip of the lifting shaft 4, and the support plate 9 is pushed up against the bottom of the bridge C, and the bridge C to be temporarily constructed on the sandle D is floated from the monkey D, and the feed shaft 3 of the transfer jack A is moved forward. As a result, the floating bridge C is supported and moved forward.

With the structure as described above, when the bridge C is moved forward, the present invention first installs the machine frame 1 immediately below the bridge C which is temporarily constructed on the sandals D etc. so as to be in the same direction as the movement direction, The platform 2 moving on the machine frame 1 is moved by the transfer jack A to one end of the machine frame 1 on the transfer jack side, and then the push-up jack B is operated to move the push-up shaft 4 of the push-up jack B upward, When the support plate 9 is pushed up onto the bridge C, separated from the sandle D, and floated up, the transfer jack A is operated in that state and the feed shaft 3 is reciprocated toward the inside of the machine frame 1. It begins to move along the machine frame 1, and accordingly, the bridge C supported by the support plate 9 begins to move forward.

Then, after the feed shaft 3 of the transfer jack A has moved forward to the maximum extent, when the push-up shaft 4 of the push-up jack B is moved downward, the bridge C is lowered and repositioned by the sandle D, and the support piece 9 is Leave C. Next, when the transfer jack A is moved back, the feed shaft 3 of the transfer jack A moves back inside the machine frame 1, and the base plate 2 for fixing the push-up jack B is returned to one end of the machine frame 1 on the transfer jack side. If it is moved and stopped, and the push-up jack B is operated again to push the push-up shaft 4 up against the bridge C, the bridge C can be moved further forward. Therefore, if this operation is repeated, the bridge will move forward. As described above, in the present invention, the transfer jack is installed in the same direction as the machine frame so that the feed shaft of the transfer jack is inserted into the machine frame, and the platform on which the push-up jack is erected and fixed on the top surface of the machine frame is reciprocated. Since the bridges are arranged freely, if the machine frame is installed in the same direction as the forward movement direction of the bridge, the bridge can be moved forward stably and reliably one step at a time, and it can also be moved safely and quickly.

The simple structure of the device makes it easy to operate, and even if a breakdown occurs, it can be quickly discovered and repaired, allowing work to be carried out safely and efficiently. , has the effect of achieving the intended purpose.
