Description

Technical Field

[0001] The utility model relates to the field of boiler inspection, in particular to a boiler inspection device. Background Art

[0002] The existing patent (publication number: CN221260304U) proposes a boiler inspection device, including a positioning component, a detection component slidably fitted on the positioning component, and two adjusting arms hinged between the positioning component and the detection component. This device solves the problem that it is difficult to perform leakage detection on boiler pressure vessels of different heights and sizes before use. However, for this device, "the feed inlet of the boiler pressure vessel to be detected is fixedly connected to the first connecting flange by bolts, and at the same time, the feed inlet of the boiler pressure vessel to be detected is fixedly connected to the second connecting flange by bolts", and the two flanges are arranged longitudinally, which requires a long-distance handling of the boiler during boiler detection and affects the convenience during pressure detection. Summary of the Invention

[0003] Aiming at the above deficiencies of the existing technology, the utility model provides a boiler inspection device. When performing internal pressure detection of a boiler, the main lifting frame is pushed to the position where the boiler to be detected is located, and the lifting belt is sleeved on both sides of the boiler to be detected. Then, the lifting motor is started to drive the bidirectional driving screw to rotate, so that the lifting rope traction blocks on both sides approach each other, and the boiler to be detected is lifted as a whole. After the boiler to be detected is lifted, it will automatically center due to its own gravity. At this time, the discharge port plugging plate can be fixedly connected to the boiler discharge port, and the feed inlet plugging plate can be fixedly connected to the boiler feed inlet. The inside of the boiler to be detected is pressurized through a pressurized air pipe, and the value of the pressure detector is continuously recorded after the pressurization stops, so as to complete the pressure detection. During the detection process, this device can move freely, and at the same time, this device can lift the boiler to be detected as a whole and then perform pressure detection, so that this device does not require a large amount of handling of the boiler to be detected during pressure detection, making the pressure detection of this device more convenient and labor-saving.

[0007] Beneficial effects: 1. When the internal pressure of the boiler is detected by the present utility model, the main lifting frame is pushed to the position where the boiler to be detected is located, and the lifting belt is sleeved on both sides of the boiler to be detected. Then, the lifting motor is started to drive the bidirectional driving screw to rotate, so that the lifting rope traction blocks on both sides approach each other, and the whole boiler to be detected is lifted.

[0008] 2. When the detection block connecting platform slides longitudinally in the present utility model, multiple longitudinally arranged longitudinal movement positioning rollers are pressed against the side of the middle positioning slideway, so that the detection block connecting platform will not generate left and right vibrations when sliding longitudinally, ensuring the stability of the longitudinal movement of the detection block connecting platform. At the same time, multiple longitudinal movement positioning rollers share the force of positioning the detection block connecting platform at the same time, reducing the pressure on a single longitudinal movement positioning roller and further increasing the stability of the movement of the detection block connecting platform.

[0009] 3. When the pressure of the boiler to be detected is detected by the present utility model, the boiler to be detected can be lifted, so that when the operator detects the bottom of the boiler to be detected, the boiler to be detected can be lifted higher, facilitating the operator to directly detect the bottom of the boiler to be detected and further increasing the convenience of this device when conducting the pressure detection.

[0010] 4. The screw connecting platform of the present utility model is threadedly connected to the bidirectional driving screw, and the threaded connection has good self-locking property, so that this device will automatically lock after lifting the boiler to be detected, ensuring the safety and stability of the lifted boiler to be detected.
