[0004] To solve the above-mentioned technical problems, this utility model proposes an auxiliary device for special equipment inspection, which can stably support hazardous chemical tanks and serve as a temporary inspection platform for hazardous chemical tanks to assist in the inspection of hazardous chemical tanks.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An auxiliary device for special equipment inspection, used for inspecting hazardous chemical containers, comprising:

[0007] The base is used to install the lifting mechanism and the load-bearing mechanism.

[0008] The load-bearing mechanism has a load-bearing plate that can be rotatably mounted on the upper end of the base around the central axis of the plate body via load-bearing components, with the upper end of the plate body centrally supporting the hazardous chemical tank to be tested.

[0009] The clamping mechanism is suspended by the rotating disc of the rotating mechanism and is symmetrically clamped to the upper part of the outer peripheral wall of the hazardous chemical tank by a pair of clamping blocks;

[0010] A rotating mechanism is used to lift and clamp the mechanism and to drive the clamping mechanism and the hazardous chemical tank clamped by the clamping mechanism to rotate synchronously around a rotating shaft, which is located directly above the center of the load-bearing plate.

[0011] The lifting mechanism is installed on the upper end of the base and a rotating mechanism is suspended by a lifting plate. It is used to drive the rotating mechanism and the clamping mechanism suspended on the rotating mechanism to lift synchronously.

[0012] The structural features of this utility model also lie in:

[0013] In the load-bearing mechanism, the load-bearing component is rotatably mounted in a downwardly recessed rotary groove at the upper end of the base, with its upper end protruding above the base and fixedly connected to the bottom end of the load-bearing plate.

[0014] The lifting mechanism includes a vertical plate, a first connecting plate, a second connecting plate, a lifting plate, a threaded plate, a screw, and a lifting motor. The upper end of the base is supported by the vertical plate. The screw is vertically and rotatably mounted between the first and second connecting plates fixed on the vertical plate, with one end coaxially connected to the lifting motor. The threaded plate is threaded onto the screw through a pre-reserved threaded hole and passes through a pre-reserved lifting guide hole on the vertical plate to connect with the lifting plate, suspending the lifting plate above the load-bearing plate. Together with the lifting plate, the lifting plate can reciprocate vertically along the lifting guide hole as the threaded rod rotates.

[0015] The rotating mechanism is mounted on the lifting plate and includes a rotating motor, a worm gear, a worm wheel, a support member, and the rotating disk. The rotating motor is mounted on the upper end of the lifting plate, with its output shaft horizontal and coaxially connected to the worm gear. The worm wheel, which meshes with the worm gear, is vertical and rotatably mounted on the lifting plate. Its bottom end is fixedly supported by a support member that can slide around the central axis of the wheel axle in a circumferential direction. The wheel axle of the worm wheel passes through the lifting plate, extends downward to below the lifting plate, and is suspended from the rotating disk.

[0016] The lifting plate is provided with a support groove, and the support component is slidably installed in the support groove around the central axis of the wheel axle in the circumferential direction.

[0017] The clamping mechanism includes a bidirectional threaded rod, a guide rod, a pair of sliding components, a clamping motor, a first fixed plate, and a second fixed plate. The first and second fixed plates are located on the upper end of the rotating disk. Two external threaded sections with opposite directions are symmetrically distributed on the bidirectional threaded rod. Both ends of the rod are supported by bearings and located between the pair of first fixed plates. One end of the rod is coaxially connected to the output shaft of the clamping motor. The guide rod is parallel to the bidirectional threaded rod and located between the pair of second fixed plates. A pair of threaded blocks are respectively threaded onto an external threaded section. Each threaded block is equipped with a set of sliding components. A movable plate in the sliding components is suspended at the bottom. The sliding components can move synchronously with the threaded blocks through the movable plate. The clamping blocks in the pair of sliding components move towards each other to the clamping position or away from each other to the release position with the pair of threaded blocks. The pair of clamping blocks in the clamping position can symmetrically clamp the upper part of the outer peripheral wall of the hazardous chemical tank to be tested, which is supported in the center of the upper end of the load-bearing disk. The pair of clamping blocks in the release position are released from the hazardous chemical tank to be tested. The displacement of the pair of sliding components is guided by the guide rod.

[0020] Compared with existing technologies, the beneficial effects of this utility model are reflected in:

[0021] This invention utilizes a rotatable support plate to support the hazardous chemical container to be tested. A lifting mechanism drives a rotating mechanism and a clamping mechanism to move up and down synchronously above the hazardous chemical container, accommodating hazardous chemical containers of different heights and specifications. A pair of clamping blocks of the clamping mechanism symmetrically clamp the hazardous chemical container on both sides of the top outer peripheral wall, achieving stable placement of the container and facilitating testing operations. Furthermore, during the testing process, the rotating mechanism can drive the hazardous chemical container held by the pair of clamping blocks to rotate, thereby taking into account the testing needs of all parts of the container's outer surface as much as possible and improving the completeness of the testing operation.

[0042] In the load-bearing mechanism, the load-bearing component 22 is rotatably disposed in the downward recessed rotary groove 11 at the upper end of the base 1, with its upper end protruding above the base 1 and fixedly connected to the bottom end of the load-bearing plate 21.

[0043] The lifting mechanism 3 includes a vertical plate 31, a first connecting plate 32, a second connecting plate 33, a lifting plate 34, a threaded plate 35, a screw 36, and a lifting motor 37.

The screw 36 is vertically and rotatably set between the first connecting plate 32 and the second connecting plate 33 fixed on the vertical plate 31. One end of the screw 36 is coaxially connected to the lifting motor 37.

The guide rod 56 is parallel to the bidirectional threaded rod 54 and disposed between the pair of second fixing plates 52. A pair of threaded blocks 55 are respectively threadedly fitted onto the pair of second fixing plates 52. On the external thread section, each threaded block 55 is equipped with a set of sliding components. The bottom end of the sliding component is equipped with a moving plate 57. The sliding component as a whole can move synchronously with the threaded block 55 through the moving plate 57. The clamping blocks 510 in a pair of sliding components move towards each other to the clamping position or move away from each other to the release position with the pair of threaded blocks 55. The pair of clamping blocks 510 in the clamping position can symmetrically clamp the upper part of the outer peripheral wall of the hazardous chemical tank 6 to be tested, which is supported in the middle of the upper end of the load-bearing plate 21.

[0049] The clamping block 510 is a flexible board, which can be made of rubber or other materials.

[0050] When used for inspecting hazardous chemical containers, this device can serve as a platform for the inspection. Its main functions are twofold: firstly, it can stably hold the hazardous chemical containers; secondly, the containers can rotate, providing assurance and convenience for inspection operations such as visual inspection, thickness measurement, leak detection, weld inspection, and corrosion detection. The following methods can be used as a reference when placing hazardous chemical containers:

[0051] Step 1: Place the hazardous chemical container in the center on the support plate on the base;

[0052] Step 2: Start the lifting motor. The lifting motor drives the screw to rotate, which in turn drives the threaded plate and the lifting plate to descend together along the lifting guide hole until the rotating plate is placed on top of the hazardous chemical tank.

[0053] Step 3: Start the clamping motor to drive the bidirectional threaded rod to rotate, causing a pair of threaded blocks to move towards each other. A pair of moving plates move synchronously and are guided by the sliding fit between a pair of sliders and guide rods until they symmetrically clamp the two sides of the top outer peripheral wall of the hazardous chemical tank and reach the clamping position. At this point, the stable placement of the hazardous chemical tank is completed.

[0054] Step 4: Conduct inspection of the hazardous chemical tanks. If the hazardous chemical tanks need to be rotated during the inspection process, the rotating motor can be started to drive the worm gear to rotate. Through the meshing transmission of the worm gear and worm wheel, the rotating disk and its clamping mechanism will rotate synchronously with the worm wheel, and then the hazardous chemical tanks will be rotated along with it through the clamping mechanism.

[0055] The following procedures can be followed when unloading hazardous chemical containers after inspection:

[0056] Step 1: Start the clamping motor, drive the bidirectional threaded rod to rotate in the opposite direction, drive a pair of threaded blocks to move in the opposite direction, and a pair of moving plates move synchronously. They are guided by the sliding cooperation between a pair of sliders and guide rods until they are separated from the hazardous chemical tank and reach the release position.

[0057] Step 2: Start the lifting motor. The lifting motor drives the screw to rotate in the opposite direction, which in turn drives the threaded plate and the lifting plate to rise together along the lifting guide hole until the rotating plate is placed above the hazardous chemical tank.

[0058] Step 3: Remove the hazardous chemical container from the support plate on the base.

[0059] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
