Referring to fig. 10, in the present embodiment, the guide wheel 321 is composed of a roller shaft 322, a forklift bearing 323, and a bearing cover 324, the roller shaft 322 is fixed to the inner gantry, the forklift bearing 323 is sleeved on the roller shaft 322, the bearing cover 324 is fixed to the roller shaft 322 by a bolt, an inner ring of the forklift bearing 323 is fixed, and an outer ring of the forklift bearing 323 is in rolling fit with the upright column of the outer gantry. The guide wheel 321 is matched with two opposite side walls of a single upright of the outer gantry, a connecting wall between the two side walls may generate certain friction with the inner gantry, a roller 326 can be arranged on the inner gantry at the moment, and the rotating axis of the roller 326 is perpendicular to that of the guide wheel 321, so that the fluency of the lifting of the inner gantry is further improved.
Based on any one of the above-described airtight inspection lid parking mount carts 1000, embodiments of the present application provide a mobile airtight inspection apparatus including an airtight inspection lid 2000 and an airtight inspection lid parking mount cart 1000. The airtight inspection cover 2000 is placed on the chassis 10 in a vertical posture, and the hoisting device 70 can hang the airtight inspection cover 2000. The movable airtight inspection device can be convenient for finding the position in the factory building for storage, and can be directly moved to the position where the inspected object is located as required without interfering the proceeding of other work in the factory building, so that the use is very convenient.
The principle of the embodiment is as follows:
in the current use of the airtight inspection cap 2000, it is lifted by means of a bridge crane. However, other more important works in the factory building also need to use the bridge crane, so that the use of the airtight inspection cover 2000 can affect the development of other more important works on the one hand, and the corresponding operation space is occupied on the other hand, and the development of other works is not facilitated.
The current factory building has corresponding work arrangement and space requirement for field use, so the use of the current airtight inspection cover 2000 is time consuming and delays other work.
In addition, in daily storage, the airtight inspection cover 2000 is buckled on the sleeper, and after the sealing rubber strip is stored for a long time, the deformation is not easy or the airtight inspection cover can not return to the initial state, so that the development of the airtight inspection is influenced. And, since it is a reverse-type, it is inconvenient for daily maintenance, and the inner surface condition of the airtight inspection cover 2000 cannot be ascertained.
In view of this, the present application provides an airtight inspection lid parking mount 1000, it can play to rise airtight inspection lid 2000 to in airtight inspection, also can save airtight inspection lid 2000, convenient maintenance, and make joint strip can not produce the deformation, guarantee airtight inspection's reliability.
In addition, the airtight inspection cover 2000 may be detachably connected directly to the lifting device 70, and used as a mobile airtight inspection device for inspecting the airtightness of the cylindrical body.
In daily storage, the second door frame 32 is in a lower position, and the upper support assembly 90 and the bottom support assembly 110 together support the airtight inspection cover 2000 in an upright position. Because the position that airtight inspection lid 2000 was located is lower, whole airtight inspection lid parking mount frame car 1000 and airtight inspection lid 2000 can all stably be deposited, can not overturn, and because can not extrude airtight inspection lid 2000's joint strip, guaranteed joint strip's is intact. And airtight inspection lid parking mount frame car 1000 can also be according to the condition of developing of other work in the factory building, with airtight inspection lid 2000 transfer under the condition that does not occupy bridge crane, it is very convenient to use.
When the airtightness inspection is performed, the airtightness inspection cap parking mount cart 1000 is moved to the vicinity of one end of the cylinder, and then the support leg frame 14 is unfolded so that the support leg frame 14 enters the support state.
Then the winch 153 works to lift the second portal 32, after the second portal 32 is lifted to a proper position, the winch 153 keeps pulling, so that the position of the second portal 32 keeps unchanged, the inserting plate of the inserting plate mechanism is adjusted to the bottom of the upright post of the second portal 32 to support the second portal 32, and the stability of the second portal 32 can be effectively guaranteed by combining the limiting and supporting effect of the locking inserting plate 3253 inserted into the clamping hole 311 on the outer portal.
Then, the chain hoist operates to adjust the height of the airtight inspection cover 2000, and to move the airtight inspection cover 2000 along the length direction of the cantilever 50 to adjust the horizontal position of the airtight inspection cover 2000 with respect to the cylinder to be inspected.
If the orientation of the hermetic inspection cover 2000 is found to be misaligned with respect to the cylinder, the swing mechanism may be driven to rotate the entire elevating bracket 30, thereby changing the orientation of the hermetic inspection cover 2000 to be aligned with respect to the cylinder to be tested, and then the hermetic inspection cover 2000 may be mounted to one end of the cylinder according to a conventional mounting procedure and a corresponding hermetic inspection operation may be performed.
After the inspection is completed, the airtight inspection cover 2000 is disconnected from the cylinder, the airtight inspection cover 2000 is moved to a position of the cantilever 50 closer to the second door frame 32, the endless chain hoist further lowers the airtight inspection cover 2000, the limit support of the pallet mechanism is released, the winch 153 works in the reverse direction, the second door frame 32 is lowered, and finally the airtight inspection cover 2000 returns to the original state. The airtight inspection cover parking mounting frame 1000 drives the airtight inspection cover 2000 to return to the storage location of the factory. It can be understood that, during the airtight inspection, the electric cabinet 1001 may be used to control the raising of the second door frame 32, the operation of the chain hoist, and the like, and the user may press the corresponding operation key. The electric control box 1001 is relatively common, and can be selected and matched by persons in the field according to requirements, which is not described herein again.
To sum up, the airtight inspection cover parking mounting frame vehicle 1000 of the present application can drive the airtight inspection cover 2000 to go up and down through the hoisting device 70, and comprehensively adjust the height of the airtight inspection cover 2000 through the lifting support 30, and make it capable of butting against the cylinder by adjusting the horizontal position of the airtight inspection cover 2000 on the cantilever beam 50. In addition, the airtight inspection cover 2000 can be stored conveniently, the damage of a sealing rubber strip of the airtight inspection cover 2000 is avoided, and the existing technical problem is effectively improved.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
