Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for transporting fireworks such as bridge girders.

Conventionally, in the construction of the chest girder, in Section 5, when transferring (i) from Kishi Kotobuki to Kyokyo, place the value wire on the transfer device,
In addition, by winding up the wire connected to the bridge girder with a winch, the 1ali QCT is pulled and transferred while sliding on the transfer device. A conventional example of the transfer device is shown in FIG.

This transfer device QJ)G and biasability C) is equipped with a large number of rollers 1.5 as sliding means, and the rollers 1.5 are connected in sets of two by a connecting rod. Roller φ
The structure is such that υ is supported on the base by the support rod αf [accompanying movement LIJ=]. This little sister's transportation outfit +ff (1)1
In this case, the bridge girder (C) and the roller C4 blade come into close contact, and one mental force is concentrated on the contact part of the roller ψη in the girder (C), which may cause damage to the bridge girder (C). This damage is vj
Tozube (Conventional bridge girders have each part reinforced to a level greater than the strength required for the main deck, so that it can withstand stress concentration during transportation. For this reason, conventional bridge girders require a large amount of steel each time, resulting in additional costs.

On the other hand, bridge girders are not only straight but also bent or curved, and when such non-linear bridge girders are transferred using the conventional transfer device I, the conventional device σ is installed. Since it is difficult to change its position and orientation, there is a risk that the bridge girder will come off the rollers 9υ. Therefore, the conventional device i! ■), the solution is to make the length of roller 0υ much longer than the width of the bridge girder, but in this way roller Q
If it is made longer, the entire device 6 becomes larger.

The present invention was made with the aim of solving the above-mentioned technical problems, and it is possible to reduce the cost of structures by transporting them without reinforcing them with conventional balls. The present invention provides a structure transfer device α which is capable of reliably transferring a non-linear structure even if the device itself is small.

In order to achieve the above object, the first light of the present invention supports an oblong elliptical support body with an IPi line part on support legs that stand up on a pedestal, and a ring-shaped chain roller is placed around the outer periphery of this support body. The movable chain roller has a width of 1J, and an infinite track fence is attached to the outer periphery of the chain roller to allow for circumferential movement.The second invention also has a pair of supports and legs on the pedestal. A hydraulic cylinder is provided to be able to slide left and right with respect to the direction in which the structure is transferred, and to urge these support legs so that they can slide independently. A long elliptical support body is constructed, and both ends of the support body are supported on support legs so as to be able to rotate left and right with respect to the transport direction of the 148 structures. 61 Ta, and an endless track belt is wound around the outer periphery of the chain roller at the circumferential movement I-If11.

That is, according to the first invention, the structure is placed on the endless track belt that runs along the straight part of the support, and the structure is pulled in that state, so that the endless track belt is flush with the structure. Since the structure is transferred by smoothly rotating along with the rotation of the chain rollers and the rotation of each roller while in contact with the chain roller, the structure does not receive concentrated stress locally at the contact part with the endless track belt. Therefore, it becomes possible to transport the structure without reinforcing it as in the past, and the cost of the structure can be reduced.

Further, according to the second investigation, in addition to the effects of the first invention, the following effects are obtained. That is, by simultaneously sliding a pair of support legs in the same direction with a hydraulic cylinder, the support body is moved in parallel, or by sliding the other support leg 2 with one support leg fixed, or By simultaneously sliding the supports in opposite directions, the support rotates to the left and right in the horizontal direction, so the position and orientation of the support can be changed according to the degree of bending of the non-linear Jr4 pickle. Even if the device itself is small, it is possible to transfer non-linear structures to M1.

Hereinafter, an embodiment of the present invention will be explained from the diagram O diagram m1.
