Description

Technical Field

[0001] The utility model relates to the technical field of pressure vessels, in particular to an auxiliary positioning device for pressure vessel detection. Background Art

[0002] Pressure vessels are special equipment. Pressure vessels refer to closed equipment that contains gas or liquid and bears a certain pressure. Pressure vessels have a wide range of uses, including industry, military industry, etc.

[0003] After the pressure vessel is produced, in order to ensure the safe use of the pressure vessel, it is often necessary to inspect the pressure vessel to ensure that the produced pressure vessel meets the standards; however, it is difficult for existing pressure vessel inspection devices to accurately position the pressure vessel, resulting in the pressure vessel being offset during the inspection process, resulting in reduced inspection accuracy and inconvenience in the inspection operation. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the utility model provides an auxiliary positioning device for pressure vessel inspection, which has the function of driving two arc-shaped plates to be squeezed toward the outer surface of the pressure vessel through the action of a spring, and then starting a motor to make the two clamps approach each other and clamp the pressure vessel, thereby solving the above-mentioned technical problems.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an auxiliary positioning device for pressure vessel inspection, comprising a base plate, a workbench is arranged on the upper surface of the base plate, a fixed plate is fixedly connected to the upper end of the workbench, a first ear plate is fixedly connected to one side of the fixed plate, a support rod is arranged at the front end of the first ear plate, a second ear plate is fixedly connected to the inner wall of the support rod, and an arc plate is welded at the front end of the support rod, a fixed block is fixedly connected to the inner wall of the front end of the arc plate, a cushion block is fixedly connected to the upper end of the base plate, and a motor is fixedly installed on one side of the cushion block.

[0008] Preferably, two first ear plates are provided, and the first ear plates are in hinged relationship with the support rod.

[0009] Through the above technical solution, the support rod is arranged inside the ear plate, and the ear plate is hinged to the support rod through a latch, that is, the support rod can move forward and backward of the ear plate, and the movement of the support rod can drive the arc plate to move.

[0010] Preferably, two support rods are provided, two second ear plates are provided, a telescopic rod is hingedly provided between the two second ear plates, a spring is provided on the outer wall of the telescopic rod, and both sides of the spring are fixedly connected to the inner wall of the support rod.

[0011] Through the above technical solution, when testing the pressure vessel, the pressure vessel is placed between the two arc plates from the upper end. When the pressure vessel is in contact with the arc plates, the two arc plates will move away from each other, so that the pressure vessel can be placed between the arc plates. At the same time, the arc plates also drive the two support rods to move away from each other. Since the support rod is hinged to the ear plate, the telescopic rod and the spring are stretched. Due to the action of the spring, the two arc plates are pressed toward the outer surface of the pressure vessel, so that the pressure vessel can be positioned and can adapt to pressure vessels of different sizes.

[0012] Preferably, a rubber pad is provided on the inner wall of the arc-shaped plate.

[0013] Through the above technical solution, when the two arc-shaped plates approach the outer surface of the pressure vessel, the rubber pads arranged on the inner walls of the arc-shaped plates can protect the outer surface of the pressure vessel, avoiding scratches on the outer surface of the pressure vessel, and at the same time increase the friction force so that the pressure vessel can be better clamped.

[0014] Preferably, the motor is rotatably connected to a bidirectional screw rod.

[0015] Through the above technical solution, the output shaft of the motor is sleeved on the bidirectional screw rod, and the bidirectional screw rod is provided with two sets of opposite threads, that is, when the motor rotates forward, it can drive the bidirectional screw rod to rotate forward, and when the motor rotates reversely, it drives it to reverse.

[0016] Preferably, a clamping plate is rotatably provided on the bidirectional screw rod.

[0017] Through the above technical scheme, after the pressure vessel is placed, the motor is started in the forward direction, and the motor drives the bidirectional screw to rotate. The clamping plates on different thread groups on the bidirectional screw move along with the thread teeth on the bidirectional screw, so that the two clamping plates are close to each other. When the clamping plates are close to each other, they touch the fixed plate, which can drive the arc plates to approach each other and clamp the pressure vessel, thereby further enabling better positioning of the pressure vessel.

[0018] Compared with the prior art, the utility model provides an auxiliary positioning device for pressure vessel inspection, which has the following beneficial effects:

[0019] 1. The utility model is provided with components such as telescopic rods and springs. When testing a pressure vessel, the pressure vessel is placed between two arc plates from the upper end. When the pressure vessel is in contact with the arc plates, the two arc plates will move away from each other, so that the pressure vessel can be placed between the arc plates. At the same time, the arc plates also drive the two support rods to move away from each other. Since the support rod is hinged to the ear plate, the telescopic rod and the spring are driven to stretch. Due to the action of the spring, the two arc plates are driven to squeeze toward the outer surface of the pressure vessel, so that the pressure vessel can be positioned and can also adapt to pressure vessels of different sizes.

[0020] 2. The utility model sets a motor, a clamping plate and other components. After the pressure vessel is placed, the motor is started in the forward direction. The motor drives the bidirectional screw to rotate, and the clamping plates on different thread groups on the bidirectional screw move along with the thread teeth on the bidirectional screw, so that the two clamping plates are close to each other. When the clamping plates are close to each other, they touch the fixed plate, which can drive the arc plates to approach each other and clamp the pressure vessel, thereby further enabling better positioning of the pressure vessel.

Since the support rod 5 is hinged with the first ear plate 4, the telescopic rod 51 and the spring 52 are driven to stretch, and since the telescopic rod 51 is hinged with the second ear plate 6, the telescopic rod 51 can be stretched flexibly, and the spring 52 drives the two arc plates 7 to squeeze the outer surface of the pressure vessel, so that the pressure vessel can be positioned, and it can also adapt to pressure vessels of different sizes.

[0029] Specifically, a rubber pad 71 is provided on the inner wall of the arc plate 7.

At the same time, the arc plates 7 also drive the two support rods 5 to move away from each other. Since the support rod 5 is hinged to the first ear plate 4, the telescopic rod 51 and the spring 52 are driven to stretch. Since the telescopic rod 51 is hinged to the second ear plate 6, the telescopic rod 51 can be flexibly stretched.
