Description

TECHNICAL FIELD The present invention relates to a traverse device for a long heavy object such as a railway vehicle, a container, and a large truck.

[Conventional technology and its problems]

Conventionally, there are various methods for moving a long heavy object, but as compared with a longitudinal movement, a lateral movement, that is,
For traverses, large-scale devices are often required due to restrictions such as safety. Hereinafter, a railroad vehicle will be described as an example of the long heavy object.

A general conventional method for moving a vehicle on a track to an adjacent track will be described with reference to FIGS.

18 and 19 are the most commonly used transfer means of the vehicle 1 by the traverser, FIG. 18 is a side view, and FIG. 19 is a plan view thereof. On the traverser 3 provided in the pit position where the floor is dug down from the surface of the track 2, the vehicle 1 is mounted together with the bogie 4 using another tow vehicle, and the traverser 3 is moved to the position of another track 5 shown in FIG. , Orbit 2
The upper vehicle 1 is transferred to the track 5.

Further, FIG. 20 is a front view showing means for transferring vehicles by an overhead crane or a tow truck, and FIG. 21 is a side view thereof. In this conventional example, at least two tow trucks or an overhead crane 7 are used to lift the vehicle 1 together with the bogie 4 with a wire or a rope 8 to form a track 2
Is transferred to the orbit 5. As a means other than these, there is an air bearing method, but it cannot be used depending on the shape of the object. Such a conventional traverse method has the following problems.

(A) A large amount of cost is required to install a device for traversing, and the construction becomes large.

(B) When a traverse device is installed, the location is limited, it cannot be traversed in other places, and it is difficult to use the device for other purposes. (C) The object to be traversed must be moved to the traverse position by another towing vehicle each time.

(D) Since the running surface of the traverser is lower than that of a general floor, there is a risk of a pedestrian falling, which is not preferable for safety.

(E) If another object interferes with the traversing object, it must be escaped to another place.

(F) In the layout of a dead end factory,
It is not possible to adopt a tact production system that sequentially feeds objects in the order of production processes.

Further, as means for intercepting a long heavy object, Japanese Patent Laid-Open No. 52-1
Some were disclosed in No. 23079.

This means connects two arms that move in a circular motion on the ground and installs a fork on the two arms to load and unload the container with the freight car. However, since the equipment on the ground side is fixed and large-scale, and the freight car has to be driven, various restrictions are caused more than the conventional apparatus, and the initial purpose especially in a factory cannot be satisfied.

On the other hand, apart from such a method, there is also a method of traversing using a so-called jack, and as this device, there are known Japanese Utility Model Publication No. 57-178008 and Japanese Utility Model Publication No. 45-16336. The former has a screw jack on a trolley that runs on rollers, and although it is simple, the number of rollers corresponding to the wheels is large, so the running resistance is large, and the directional movement of the trolley is constant due to the resistance from the approximate surface. There is a problem that it is difficult to fix in the direction and it is difficult to set the course.

Further, the latter cannot run while supporting a heavy object, and even if it can run by wheels, it cannot solve the above-mentioned problems of increasing running resistance and maintaining the direction of the carriage.

[Means for Solving the Problems]

The configuration of the present invention that solves the problems of the prior art is such that a main wheel attached to an axle is mounted on the lower front side of a bogie frame, and a long heavy object (target) is mounted on the upper front side of the bogie frame. A supporting device having a supporting surface having a region in which a tipping moment against the contact surface due to its own weight is larger than a moment due to a driving force acting on the contact surface between the object) and the bogie frame; An elevating device for vertically elevating the support device is provided, and a vertical line of the center of the grounding line of the main wheel is set within the support surface of the support device to form a trolley, and two trolleys are set as two sets. A combination of more than one set, and a main wheel attached to an axle is mounted on the lower front side of the bogie frame, and a long heavy load (target) is mounted on the upper front side of the bogie frame. Object) and the trolley frame body A support device having a support surface having a region in which a tipping moment that acts on the contact surface due to its own weight is larger than that of the object, and an elevating device for vertically elevating the support device. Set the vertical line of the grounding wire center of the above in the supporting surface of the above supporting device, and further,
It is characterized in that the center of the lifting device coincides with the vertical line to form a trolley, and two trolleys constitute one set, and two or more sets are combined.

[Action]

 The operation of the present invention is as follows.

Each trolley has a main wheel, which is fixed in a certain direction during transportation due to its own weight. Also, when the guide wheel is unloaded,
Alternatively, it is used for incorporation into an object and positioning, and the handle is steered by changing the direction with a handle. A trolley having a drive unit is self-propelled, and a trolley without a drive unit is manually handled and placed at a support position of an object.

Next, the elevating device is actuated, and the object is lifted by the supporting device having the supporting surface and set to the required height. This operation will be described later.

The object and the supporting device are configured to be fitted to each other so as not to slip in the horizontal direction due to the force received from the road surface at the time of transportation, and this fitting force acts on the trolley as well as the friction force due to the own weight of the object. The object is firmly fixed. Thereafter, when the guide wheel is pulled up and separated from the ground, the supporting center, that is, the point of action of the force, becomes the center of the axle of the main wheel, so that the truck no longer falls.

Since this fixing force is caused by the weight of the object, it is difficult for the dolly to change its direction by an external force, and it is easy to maintain the moving direction fixed. Further, during traverse, the guide wheels are not in contact with the ground and are supported only by the main wheels, so that the running resistance is small and the movement is easy.
