The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The first embodiment is as follows:

as shown in fig. 1-3, the object transferring cylinder device for pressure-bearing equipment of the present invention includes a cylinder 16 (steel cylinder, the outer wall of the cylinder is welded in the cabin 15) welded on the cabin 15 and communicated with the interior of the cabin 15, two ends of the cylinder 16 are open, one end (opening) of the cylinder extends into the cabin 15 and is communicated with the interior of the cabin 15, and the other end (opening) is located outside the cabin 15 and is provided with an annular door seat 11. The door seat 11 is a steel bearing part, is an installation seat for fixing the keyhole 1, the door shaft seat 12 and the sealing strip 17, and is combined with the door 6 to form a closed bearing part.

A door 6 capable of plugging or opening the outer openings of the door seat 11 and the cylinder 16 is arranged in the door seat 11; one side of the door 6 is hinged on the door seat 11, and the other side is locked on the door seat 11 through a locking mechanism (the locking mechanism is used for locking the door 6 on the door seat 11 so as to block the door seat 11 and the barrel 16). The door 6 is a steel component with bearing capacity, and the door shaft 14 is arranged on the door shaft seat 12 and can be opened and closed in a rotating mode, the door 6 can be opened to transfer articles into the cabin 15 through the barrel 16, and the door 6 and the cabin 15 can be closed to form a pressure container. The door 6 is hinged to the door seat 11 in the following manner: one side of the door 6 is hinged on the door seat 11 through a door axle seat 12 and a door axle 14, wherein the door axle seat 12 is two cylinders which are installed on the door seat 11 and have opposite holes, the door axle 14 is fixed on the door 6, and two ends of the door axle are respectively rotatably inserted in the door axle seat 12. In order to reduce friction and reduce the resistance of the door shaft 14 in the rotating process, bushings 13 are sleeved at two ends of the door shaft 14; the bush 13 is also rotatably inserted in the door shaft seat 12, and the bush 13 is a metal structural member with a smooth surface, so that friction can be effectively reduced.

The door 6 is provided with a negative pressure gauge 18 and a communication valve 19. The negative pressure gauge 18 is usually an existing negative pressure gauge and is used for observing a pressure value in a pressure environment; the communicating valve 19 is a conventional steel pressure relief device, and when a small amount of pressure difference exists between the inside and the outside of the cabin body 15, the communicating valve 19 can be used for releasing air to balance the air pressure inside and outside the cabin body 15, and then the door 6 can be opened easily.

The specific structure of the locking mechanism is further described below, and the locking mechanism includes a keyhole 1, a latch bolt seat 3, a latch bolt 9, an eccentric shaft 8, and a handle 2.

The keyhole 1 is arranged on the door seat 11, and a clamping groove is arranged on one side of the keyhole 1 facing the door. The keyhole 1 is a steel part and has pressure bearing capacity, and when the door 6 is in a closed state, the bolt 9 can be pushed into the keyhole 1 to lock the door 6 in the closed state.

The bolt seat 3 is arranged on the door 6 corresponding to the keyhole 1, and a sliding groove is arranged on one side of the bolt seat 3 facing the keyhole 1. The lock tongue seat 3 is also a steel part, is a fixing part for installing the lock tongue 9 and the eccentric shaft 8 and has pressure bearing capacity.

The locking bolt 9 can be installed in the sliding groove in a left-right sliding mode, a strip-shaped groove is vertically arranged on the front side face of the locking bolt 9, and the upper end and the lower end of the strip-shaped groove are arc faces. The bolt 9 is a steel bearing part, and can be driven to slide back and forth in the chute of the bolt seat 3 by the rotation of the eccentric shaft 8, so as to realize the functions of locking and unlocking the door 6.

The front end of the eccentric shaft 8 is rotatably arranged on the bolt seat 3, and the eccentric part (eccentric cylinder) at the rear end is embedded in the strip-shaped groove (drives the bolt seat 3 to slide back and forth in the sliding groove). The eccentric shaft 8 is a conventional steel part, and when it rotates, the eccentric action drives the bolt 9 to slide left and right, and its eccentric stroke can make the door 6 in a locked and unlocked state.

The handle 2 is rotatably arranged outside the bolt seat 3 and is fixedly connected with the front end of the eccentric shaft 8; after the door is closed, the handle 2 is pulled, the handle 2 can drive the eccentric shaft 8 to rotate, the eccentric part of the eccentric shaft 8 rotates along with the eccentric shaft and pushes the lock tongue 9 to slide out or slide into the sliding groove of the lock tongue seat 3, and the lock tongue 9 enters or is separated from the clamping groove of the keyhole 1. The handle 2 is a steel part, and the handle 2 is rotated to form a force arm to drive the eccentric shaft 8 which is connected with the handle to rotate. Furthermore, protective patterns or anti-slip sleeves can be arranged outside the handle 2.

In order to ensure the sealing performance, an annular sealing strip 17 is arranged on the inner side wall of the door seat 11. The sealing strip 17 is a soft rubber-like product which prevents leakage of the pressure environment when the door 6 is closed and locked.

When articles need to be transferred in the cabin body 15 under the pressure environment, the door 6 can not be opened due to the existence of the internal and external pressure difference, the communicating valve 19 needs to be rotated and unscrewed to enable the internal and external air of the cabin body 15 (the barrel 16) to be communicated to achieve pressure balance, when the negative pressure meter 18 displays that the pointer returns to zero, the handle 2 is rotated anticlockwise, the handle 2 drives the eccentric shaft 8 to rotate to pull the bolt 9 to be opened, the handle 2 is pulled to open the door 6, after the articles needing to be transferred are placed in the barrel 16, the handle 2 is pushed to enable the door 6 to be in a closed state, the handle 2 is rotated clockwise to enable the handle 2 to drive the eccentric shaft 8 to rotate, and the eccentric shaft 8 pushes the bolt 9 to the lock hole 1 to be locked under the action of the eccentric distance.

Example two:

the difference between this embodiment and the first embodiment is:

in order to limit the sliding direction of the bolt 9, a guide block 7 is transversely arranged at the position of the door 6, which is positioned in the sliding groove of the bolt seat 3; a guide groove matched with the guide block 7 is correspondingly and transversely arranged on the back of the lock tongue 9; the bolt 9 can move left and right in the sliding groove of the bolt seat 3 along the guide block 7 and enter or leave the clamping groove of the keyhole 1. The guide block 7 is a steel part which is mounted in a recess in the door 6.

Example three:

the difference between this embodiment and the first or second embodiment is:

in order to achieve the purpose of safe use, the danger of injuring people caused by the mistaken opening of the lower door 6 by misoperation of the lock tongue 9 and the danger caused by the rapid pressure loss of the cabin body 15 are prevented.

The delivery cylinder device for the pressure equipment further comprises a safe self-locking mechanism, and the safe self-locking mechanism comprises a self-locking pin 10, a joint 5, a guide pipe 4 and a limiting groove.

The self-locking pin 10 is arranged on the bolt seat 3, and a pin shaft at the lower end of the self-locking pin 10 can extend into the bolt seat 3 under external force (the self-locking pin 10 is usually formed by combining a plurality of parts such as a pin shaft, a spring, an outer steel sleeve and the like, the spring is sleeved in the region from the lower step of the pin shaft to the bottom of the outer steel sleeve, a limiting nut is screwed at the bottom of the pin shaft to limit the position of the pin shaft, when the pin shaft is subjected to external pressure, the spring is compressed, the pin shaft moves downwards along the outer steel sleeve, when the pressure on the pin shaft disappears, the spring resets, the pin shaft moves upwards under the action of the spring to reset, and finally the positioning effect is achieved). The self-locking pin 10 is a safety self-locking device under the existing pressure environment, when pressure exists in a cabin body 15 (a barrel 16), after the air pressure is applied to the self-locking pin 10 through the PU guide pipe 4, a pin shaft of the self-locking pin 10 automatically pops out to be clamped in a limiting groove on the lock tongue 9, the stroke of the lock tongue 9 is limited, and the safety problem caused by opening of the door 6 under the pressure environment is avoided. After the pressure in the cabin 15 is balanced with the outside, the pin shaft of the self-locking pin 10 retracts to the original position again under the action of the spring, and the movement of the lock tongue 9 is not limited any more.

The connector 5 is mounted on the door 6 and communicates with the interior of the barrel 16.

Two ends of the conduit 4 are respectively communicated with the self-locking pin 10 and the joint 5. The conduit 4 is a PU pipe, and is a pressure-bearing hose for communicating the self-locking pin 10 (communicating with the top of an outer steel sleeve of the self-locking pin 10) and the cabin body 15.

The limiting groove is arranged on the lock tongue 9 corresponding to the self-locking pin 10, and after the lock tongue 9 is inserted into the keyhole 1, the limiting groove is positioned under the self-locking pin 10.

When the internal pressure and the external pressure of the cabin body 15 are unbalanced, the pressure in the cabin body 15 applies pressure to the self-locking pin 10 through the PU guide pipe 4 and the joint 5 which are communicated, the pin shaft of the self-locking pin 10 moves downwards under the influence of the pressure and extends into the limiting groove on the locking tongue 9, and the situation that the locking tongue 9 is automatically opened to hurt people and cause the danger caused by the rapid pressure loss of the cabin body under the misoperation is prevented through limiting. So as to achieve the purpose of safe use.

It is to be noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.

The scope of the present invention is not limited to the technical solutions disclosed in the embodiments, and any modifications, equivalent substitutions, improvements, etc. made to the above embodiments according to the technical spirit of the present invention fall within the scope of the present invention.
