Description of the Related Art A horizontal cylinder type pressure vessel (can) is a pressure vessel for performing various processes and medical treatment by closing both ends in the axial direction of the cylinder with disc-shaped lids to make the inside high or low pressure. At least one of the lids is provided so as to be openable and closable so that people and things can enter and leave it. The lid is opened and closed by overhanging the lid open just above the can body, which is important because it requires less floor space and space.

As a mechanism for opening and closing the lid body 23 of the above, a pillar 21 is erected on the base 20, and a sleeve 31 is provided on the pillar 21 so as to be swingable via a shaft 30. The sleeve 31 is provided with rollers 36, 37, 38. , A hydraulic cylinder 26 that connects an arm 28 slidably held by a cover 39 to a lid 23 and that is swingably supported by a shaft 25 between the arm 28 and the base 20.
Is connected to the piston rod 27 of the shaft 29 by a shaft 29, and an equalizer 33 is swingably supported on the base 20 by a shaft 35.
The receiving portion 34 is provided with a pin 32 projecting from the arm 28 so as to be engageable therewith.

The arm 28 translates forward because 6 is tilted forward. The arm 28 includes a sleeve 31 and rollers 36-
Since it is supported by 39, there is little sliding resistance and it slides out smoothly. Further, since the equalizer 33 is supported on the lid body 23 side, the left and right arms 28 move while maintaining the left and right parallelism. Is pulled away from the end of the pressure can 22, the claw 42 comes out from the notch 43, and the lock ring 4

It can be prevented by a. Then, when the lid body 23 becomes substantially horizontal above the can body 22, the safety lock device 48 operates. That is, the pin 53 provided on the bracket 52 projecting from the lid 23 engages with the recess of the hook 51 swingably supported by the shaft 50 on the bracket 49 fixed to the upper portion of the can 22 to engage the lid 52. Hold it fixed so that 23 does not move.

Comes out of the recess of the hook 51. Therefore, when the hydraulic cylinder 26 is operated to contract the piston rod 27, the lid body 23 is brought into a vertical state via a path opposite to the above, and the pin 32 of the arm 28 engages with the receiving portion 34 to move the arm 28. It is supported by the equalizer 33.

Therefore, when the claw portion of the lid body 4 is fitted into the cutout portion 42 of the lock ring 41 and the movement of the lid body 23 is stopped, the hydraulic cylinder 4
4 is operated to contract the piston rod 45 and the lock ring 41 is rotated to move the notch from the claw,
The lid 23 was fixed so as not to come off the pressure can 22.

Since it is necessary to perform the parallel movement operation to and the subsequent operation of overhanging due to the rotation of the lid body 23, the mechanism is complicated, the number of parts is increased, and the cost must be increased. There are drawbacks.

That is, in the vicinity of the opening of the can body fixed to the lateral location, a rolling <br/> times frame pivotally journaled to a site which is fixed to the can body, through the hinge bracket to said transfer times frame lid The body is rotatably supported, and the swivel plate is rotatably supported on the turning frame, and the swivel plate and the lid are connected by a link, while the swivel plate closes the lid. State
Does not come into contact with the turning frame before the end of the opening operation of the lid.
A pin that comes into contact with the turning frame is provided, and a drive unit that rotates the swivel plate is provided.

The recess 28 of the hook 27 that is swingably supported by the shaft 26
There is provided a safety lock device 29 which is fixedly held to prevent the lid body 4 from moving by engaging with the. Hook 27 is a piston rod recess 28 rotates clockwise by 31 pin 4 advancing and retreating from the oil pressure cylinder 30 fixed to the bracket 25
It can be removed from a. The safety lock device 29 is substantially the same as that of the conventional example.

１とのロックを解く。To explain the operation of the above embodiment, when the lid 4 is opened from the state shown in FIG. 1 in which the lid 4 is closed,
First, as shown in FIG. 4, the piston rod 31 of the hydraulic cylinder 30 is projected and the hook 27 is rotated clockwise about the shaft 26, whereby the pin 4a of the lid 4 is rotated.
By releasing the engagement of the concave portion 28 with the lid 28, the lid body 4 and the can body 1 are unlocked.

It is ready to be removed from the edge of the opening.

の軸７中心で時計回りに回動させる。Then, by driving the hydraulic cylinder 19 to extend the piston rod 18, the swivel plate 12 rotates clockwise about the shaft 11. Therefore,
The link 15 moves to the lid 4 side via the shaft 14, and the shaft 13 (pin) contacts the turning frame 8 to rotate the turning frame 8 clockwise around the shaft 7.

る。Therefore, as shown in FIG. 5, the lid body 4 rotates counterclockwise about the shaft 10 of the hinge bracket 9 to open the opening of the can body 1, and further as shown in FIG. As the turning frame 8 is pushed by the shaft 13 of the swivel plate 12 and rises, the lid body 4 is gradually lifted to the upper portion of the can body 1.

く安全である。Then, as shown in FIG. 7, when the piston rod 18 is fully extended, the lid body 4 overhangs substantially parallel to the upper portion of the can body 1 and stops. Therefore, when the piston rod 31 is retracted into the hydraulic cylinder 30 of the safety lock device 29, the hook 27 rotates counterclockwise about the shaft 26 due to its own weight, and the recess 28 engages with the pin 4a to cover the lid body. The horizontal state of 4 is locked. Therefore, the state in which the lid body 4 is overhung does not unravel inadvertently and is safe.

４は缶体１から自由な状態となる。The action of closing the lid 4 is such that when the piston rod 31 is first projected from the hydraulic cylinder 30 of the safety lock device 29, the hook 27 rotates clockwise around the shaft 26 and the recess 28 is formed. When the lid 4 is disengaged from the pin 4a, the lid 4 is free from the can 1.

Although the turning frame 8 is pivotally supported by the column 6, it may be pivotally supported by the body of the can body 1 if possible, and the hydraulic cylinder 19 for rotating the swivel plate 12 and the piston rod 18 thereof.
May be replaced by any other suitable rotary drive means, such as hydraulic or electric motors and wire ropes towed by them.
