The embodiment has the advantages that the meshing transmission mode of the gear 302 and the rack part 3041 is used for determining whether the working air cylinders 401 are positioned on the same height by observing whether the heights of racks of each group of racks extending out of the top of the water tank 2 are the same, the adjustment mode is simple and convenient, the sliding mode of the T-shaped groove 3031 ensures that the sliding plate 304 can only move in the height direction, running positions are difficult to occur in other directions, and the embodiment is more stable and reliable.
Example 3
The third embodiment of the pneumatic-hydraulic detection device for air-filled sealed pipe fittings is different from the first embodiment in that, as shown in fig. 1 to 2:
The automatic pressure control device comprises a chassis 1, a linear driving assembly 4, a lifting mechanism 3, a control panel 8, an air release valve 504, external pressurizing equipment and control panel 8, wherein the control panel 8 is arranged at the top end of the outer side wall of the chassis 1, the linear driving assembly 4 and the lifting mechanism 3 are electrically connected with the control panel 8, the air release valve 504 is electrically connected with the control panel 8, the control panel 8 is electrically connected with the external pressurizing equipment and is used for realizing pressurizing control on a pipe or a pipe to be tested, and the electric connection arrangement of the control panel 8 can enable the detected action process to be relatively semi-automatic, so that the working efficiency is improved.
In the working process of the above embodiment, the control panel 8 is operated to start the external pressurizing device to pressurize the inner air cushion 5023 and the outer air cushion 5024 of the clamping assembly 502, and then the control panel 8 is operated to control the lifting mechanism 3 to lift and descend, so as to control the linear driving assembly 4 to fix the pipe or the pipe in the horizontal direction.
The embodiment has the beneficial effects that the electric connection setting of the control panel 8 improves the automation degree of operation, reduces some complicated manual operation procedures and improves the working efficiency.
In the specific content of the above embodiment, any combination of the technical features may be performed without contradiction, and for brevity of description, all possible combinations of the technical features are not described, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
It is to be understood that the above examples of the present utility model are provided by way of illustration only and not by way of limitation of the embodiments of the present utility model. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments. Any modification, equivalent replacement, improvement, etc. which come within the spirit and principles of the utility model are desired to be protected by the following claims.
