DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle for moving a hall, which is provided with a conveyor for moving the vehicle into and out of the cremation furnace, and a conveyor for moving the vehicle into and out of the cremation furnace. With the front end of the conveyor protruding into the front room, the connection of the cremation vehicle to automatically switch the connection of the trolley from the conveyor for the carrier to the conveyor for the front room, or from the conveyor for the front room to the conveyor for the carrier. Related to the device.

[0002]

2. Description of the Related Art Conventionally, in the connection device for a cremation cart described above, as shown in Japanese Utility Model Laid-Open Publication No. 60-196126 shown in FIG. Is provided on each of the conveyors for transporting vehicles, a support rod 85 is provided on a portion between the pair of left and right chains, and the conveyor for the front room is provided with a locking groove on a portion of the chains. A piece 86 is protrudingly provided, a locking piece 87 is provided on the rear side of the back surface of the bogie to engage with the support rod, and a bracket 88 is vertically provided on the front side of the back side of the bogie, and fitted into the locking groove on the bracket. The whole connecting rod 89 is supported so as to be able to move up and down, and furthermore, a lever 90 is pivotally attached to the front chamber so as to be able to swing up and down, the rear end of the lever is extended to the support piece, and the front end of the lever is connected to the front chamber. There is a structure that protrudes more toward the carrier.

[0003] When the connection of the truck is switched from the conveyor for the transport vehicle to the conveyor for the front room, the transport of the truck is automatically performed by driving the conveyor for the transport vehicle to move the truck from the transport vehicle to the front room. Cut off from the car conveyor,
After that, the bogie is connected to the anterior room conveyor by lowering the transport vehicle.
Since the operation of newly connecting is performed intermittently (separately), it is desired to complete the switching operation more quickly.

[0004] More specifically, the connection is released by driving the conveyor for the transport vehicle with the carriage approaching the front room and reversing the traveling direction of the support rod (changing from left to right). The rod naturally separates from the locking piece and is complete. In addition, the new connection, by approaching the above-mentioned bogie, the lever is held in a raised state, and in this state, the conveyor for the transport vehicle is driven and the bogie is sent to the front room, and by the feeding, By raising the connecting rod supported below the bracket along the lever, holding the connecting rod above the locking groove, and pulling the bogie away from the front chamber, the connecting rod moves into the locking groove. Depressed,
This completes.

[0005] Further, when the connection of the truck is switched from the conveyor for the front room to the conveyor for the carrier, the carriage for the front room is stopped after the carriage is moved to near the entrance of the front room, and then the carrier is moved to the front room. It was completed by approaching and finally driving the conveyor for the vehicle, and the coupling and decoupling operations were performed intermittently as described above.

[0006] In addition, in order to reliably carry out the work of connecting the bogie, the above-mentioned connecting device accurately sets the distance between the locking piece and the bracket and the stop position of the supporting piece with respect to the conveyor for the transport vehicle. Need to be kept. However, the location where the transport vehicle stops in proximity to the anterior chamber is slightly different for each crematorium, so it was necessary to adjust the distance between the locking piece and the bracket at the site accordingly. And this adjustment operation was a troublesome operation of moving the mounting position of the locking piece and the bracket back and forth.

[0007]

The first object of the present invention is as follows.
An object of the present invention is to provide a cremation truck connecting device capable of quickly performing a work of switching a truck connection.

According to the second aspect of the present invention, in addition to the problem to be solved by the first aspect of the present invention, it is possible to easily perform an adjustment operation necessary for reliably performing a connection switching operation. An object of the present invention is to provide a connecting device for a cremation cart.
