Description

An autoclave door opening device

technical field

The utility model relates to the field of mechanical manufacturing, in particular to an autoclave door opening device.

Background technique

Under the prior art, the commonly used autoclave door opening device is generally a suspension type, and its device is composed of a boom, a support frame, a kettle crown, a door opening and closing motor, and an opening and closing lock motor. Its operation mode is that one end of the boom is connected to the central axis of the kettle door, and the other end is fixed on the support frame of the kettle body, and the opening, closing and rotation of the kettle door are controlled by the motor drive. The disadvantages are as follows: a) Because the connection between the kettle door and the kettle body support frame is a soft connection, when the kettle door is opened, the motor stops due to inertia, and the kettle door will swing to a certain extent. When it is closed again, manual reset is required, otherwise The kettle door cannot be closed normally; b) Since the motor is used as the driving device, if the switch lock motor is started when the kettle door is not closed in place, the switch lock motor is easily damaged; c) Since the kettle door support frame is on the top of the kettle body, the height It is relatively high, and its adjustment device is also on the top of the kettle body, so it is not convenient to adjust the kettle door and maintain it.

Utility model content

The utility model aims at the above deficiencies and provides an autoclave door opening device with reasonable design, simple structure, low production cost and convenient use.

The technical scheme that the utility model adopts for solving the problems of the technologies described above is:

A door opening device for an autoclave. Its structure includes a kettle door (1), a cross arm (2), a vertical shaft (3) and various connectors. The kettle door (1) is fixed on the side of the autoclave through the cross arm (2) and the vertical shaft (3). The opening and closing and rotation are driven by the hydraulic cylinder (4).

The kettle door (1) opens the door for the cross arm (2), that is, the kettle door (1) is supported by the cross arm (2) to open to the left or right side of the kettle body (5).

There are 8 adjusting bolts (7) on the central gland (6) of the kettle door (1), which are convenient for vertical and horizontal adjustment of the kettle door (1).

The vertical shaft (3) is fixed on the side (left or right side) of the kettle body (5), and the front, rear, left, right, up and down of the vertical shaft have adjusting bolts (7) for easy adjustment.

The drive of the door opening device of the autoclave is a hydraulic cylinder (4), one end of the door opening cylinder (8) is connected to the fixed end of the kettle body (5) and the cross arm (2), and the rotary door cylinder (9) is fixed on the kettle body (5). On the blue, it is connected with the kettle door (1) by a pin shaft.

Both the inside and the outside of the transverse arm (2) are provided with reinforcing vertical plates (10).

Fig. 2 is a top structural diagram of an autoclave door opening device of the present invention.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

As shown in the figure, an autoclave door opening device is composed of a kettle door, a gland, a cross arm, a vertical shaft, a vertical shaft support seat (11), a door opening oil cylinder and a special oil cylinder. The support seat of the kettle door is welded and fixed on the side of the kettle body (you can choose on the left or right side), the vertical shaft is installed on the support seat, one end of the cross arm is welded on the vertical shaft, and the other end is connected with the kettle door by the gland, so as to support the kettle door Get up to realize the opening and closing and rotation of the kettle door. When the kettle door is not locked, the kettle door will be opened when the door-opening cylinder shrinks, and the kettle door will open to the side front of the kettle body; when the door-opening cylinder is extended, the kettle door will be closed. When the kettle door is closed in place, the kettle door rotary plate on the kettle door is combined with the pin shaft on the rotary door cylinder. At this time, if the rotary door cylinder is extended, the kettle door can be locked; otherwise, the kettle door will be unlocked when the cylinder shrinks. . After the kettle door is installed, first adjust the adjusting bolts on the vertical shaft to roughly adjust the vertical, horizontal and height of the kettle door, and then fine-tune the 8 adjusting bolts on the gland to finally adjust the kettle door in place, so that the door can be opened and closed freely , Open and close freely.

The above is a further detailed description of the utility model in conjunction with specific preferred embodiments, and it cannot be assumed that the specific implementation of the utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the utility model belongs, without departing from the concept and connotation of the utility model, some simple deduction or replacement can also be made, which should be regarded as belonging to the protection scope of the utility model.
