There are those described in each publication of No. 0243.

In each of these inventions, a coffin pedestal on which a coffin is placed is positioned below a cremation chamber having a lower opening, the coffin pedestal is raised by an elevating device, and the coffin is placed into the cremation chamber from the lower opening. It was configured to carry a loading platform.

[Problems to be Solved by the Invention] However, in the conventional invention as described above, the entire coffin platform was raised and lowered by a lifting device, so an extremely large load was placed on the lifting device to raise and lower it. The equipment needed to be constructed with high-output equipment such as a hydraulic system.

Therefore, there was a risk that the output would be reduced due to an unexpected accident such as a breakage of the pressure oil piping, and the coffin stand would naturally fall, separating from the cremator wall and breaking the seal.

Furthermore, in order to obtain high output, the hydraulic dawn structure has become larger and more complex, and the battery that serves as the power source has also had to become larger.

This invention was devised in view of the above-mentioned conventional problems, and an object of the present invention is to provide a cremation cart capable of sealing between a coffin and a cremation chamber without lifting a heavy coffin stand.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a truck body with a coffin mount, and an incineration system in which the truck body moves and the coffin mount has a lower opening. a sealing member positioned below the chamber and moving up and down along the side of the coffin stand to seal between the coffin stand and the cremation chamber; and a lifting drive device for driving the sealing member up and down. The cremation cart was constructed with

[Function] According to the configuration of the present invention, when the body of the cremation cart moves and the coffin table is positioned below the cremation chamber having the lower opening, the coffin can be placed without raising or lowering the coffin table itself. By raising and lowering a light sealing member along the side of the platform using the lifting drive device, it is possible to completely seal between the coffin platform and the cremation chamber.

[Example] Hereinafter, an example of the present invention will be described based on FIGS. 1 to 5.

The upper end of the link 41 is pivotally connected to the sealing member 17 by a pin 59, and the lower end is provided on the rail 55 via a roller 61 so as to be horizontally movable.

The links 43 and 45 are connected to each other by having one end pivotally connected by a pin 63, the other end of the link 43 is pivotally connected to the sealing member 17 by a pin 64, and the other end of the link 45 is connected to the main body 13. It is pivotally connected to the rail 57 of the main body via a pin 65.

The bin 51 and the bin 63 are connected by a connecting rod 47.

The lifting hydraulic jack 35 is installed on the trolley body 9,
It is connected to the link 41 via an operating rod 67.

The drive mechanism 37 of this hydraulic jack 35 includes six eccentric discs attached to the drive motor 29, and the eccentric discs 6
The crank movement mechanism 73 connects the cylinder part 71 of the hydraulic jack 35 to the cylinder part 71 of the hydraulic jack 35. That is,
The six eccentric discs rotated by the drive motor 29 apply crank motion to the crank mechanism 73, and this crank motion increases the oil pressure in the cylinder section 71, causing the operating rod 6 to move.

moves forward (at this time, the eccentric disk 69 is not driven to rotate).

) Limits 1 to switches 85 provided at the front end of the truck body 9
When sensing the forward end, the drive motor 29 is stopped and the cremation cart 7 is stopped.

Further, when the forward/backward switching clutch lever 81 is operated to the backward side, the drive motor 29 rotates in the opposite direction, the rubber tires 25 are driven in the reverse direction via the belt transmission mechanism 27, and the cremation cart 7 moves backward.

In addition, when the cremation cart 7 moves forward or backward, it is guided by a guide rail 87 (FIG. 3) attached to the floor 13 within the crematorium 1.

Furthermore, when the up/down switching clutch lever 83 is operated to the up side, the drive motor 29 rotates in the forward direction to rotate the eccentric disk 69 (at this time, the belt transmission mechanism 27 is not driven to rotate). By applying a crank motion to the crank motion mechanism 73, the oil pressure in the cylinder portion 71 of the hydraulic jack 35 is increased, and the operating rod 67 is extended.

to rise.

Further, when the ascending/descending switching clutch 83 is operated to the descending side, the hydraulic pressure of the cylinder portion 71 of the hydraulic jack 35 is released and the operating rod 67 is shortened. This shortening of the operating rod 67 causes the link mechanism 33 to collapse and lower the seal member 17.

An apron 89 is attached to the outside of the seal member 17.

A cam surface 3a is formed on the front surface of the loading/unloading door 3 of the crematorium 1, and when the loading/unloading door 3 is closed, the cam surface 3a
is pressed by the roller 91, and the carry-in hanging door 3 is cremated.
It is designed to come into pressure contact with the wall 1f side.

According to the above embodiment, since the light sealing member 17 is raised and lowered to seal between the crematorium F3 wall 1f and the coffin stand 11, the lifting mechanism 19, its piping (not shown), etc. are damaged. However, the seal can be reliably held without the seal member 17 falling.

As a result, unlike in the past, outside air will not flow into the incineration chamber 1a due to seal breakage and normal combustion conditions will be impaired, or combustion gas and odor will not leak outside.

Furthermore, the elevating mechanism 19, the link mechanism 33, etc. can be made smaller and simpler.

In the above embodiment, the upper surface of the seal member 17 is the cremator wall 1f.
Although it has been described that the upper surface of the sealing member 17 is in close contact with the cremator wall 1[, the upper surface of the sealing member 17 may be in contact with the cremator wall 1[] to such an extent that even if combustion gas or odor leaks to the outside, there is no problem.

Further, although a hydraulic jack for lifting and lowering is used for the lifting mechanism, it is not limited to hydraulic jacks. That is, the hydraulic jack for lifting and lowering may not be driven by a motor, but may be operated by foot or manually.

Furthermore, for raising and lowering the sealing member, a chino and a so-called sprocket, or a belt and a pulley may be used instead of the link ml.

Further, a female thread is attached to the sealing member, and this female thread is screwed into a male thread rotatably protruding from the main body, and by rotating the male thread, the sealing member is moved up and down via the female thread. You can also.

Further, in the above embodiment, the sealing member is formed on the left and right side walls and the front wall of the coffin mount, that is, in a portion other than the portion where the haiku hanging door is located, but it can also be formed along the entire circumferential wall of the casket mount.

Note that the present invention is not limited to the above-described embodiments, and can be implemented in other embodiments by making appropriate changes.

[Effects of the Invention] As is clear from the above description, according to the configuration of the present invention, it is possible to lift the light sealing member and seal between the coffin table and the cremation chamber without lifting the heavy coffin table. can. Therefore, the seal will not break during the cremation of the corpse.
