Description

Technical Field

[0001] This utility model belongs to the field of digital X-ray inspection technology, and relates to a fixing device, particularly a fixing device for a digital X-ray inspection instrument for pressure pipelines. Background Technology

[0002] As traditional film photography gradually transitioned to digital photography in daily life, radiographic examination techniques used in medicine and industry also began to develop digital imaging technology in the 1990s. Digital radiography (DR) is a radiographic examination technique that can obtain digital images. It includes two commonly used methods: Director digital panel radiography and Computed radiography (CR). The former, often referred to as DR technology, is a direct digital radiographic examination technique. It mainly uses a rigid flat panel detector, and data acquisition takes only a few seconds, enabling near real-time imaging. It is currently widely used in the medical industry (such as chest X-ray examinations) and industrial mass production inspection (as shown in the figure below). The latter, CR technology, mainly uses a cuttable and bendable image plate (IP) to replace traditional film to record imaging information. The information on the IP plate is then read by a scanning device, and a computer generates a digital image. Therefore, it is also called indirect digital radiographic imaging technology. Compared with traditional film, IP plates can be reused for a limited lifespan.

[0003] Current digital X-ray inspection technology is used to monitor some pipeline equipment, but the surface of pipeline equipment is curved, making it difficult to use existing fixing devices.

[0004] A search revealed a Chinese patent document disclosing a fixing device for a digital X-ray inspection instrument [Application No.: 202320515287.6; Publication No.: CN 220508824 U]. This fixing device, relating to the field of digital X-ray inspection technology, includes a fixing device and a strap. The fixing device comprises two fixing seats, each with an internal cavity. A connecting strip is fixedly installed on the top of one fixing seat, and a connecting groove is provided on the top of the other fixing seat. A fixing knob is provided on the top of the connecting groove, which is fitted onto the outside of one end of the connecting strip. This invention, by having an internal cavity in the fixing seat, facilitates the fixing and installation of a flat panel inspection instrument, protecting it. The connecting strip facilitates the fixed connection of the two fixing seats, thus securely fixing and protecting the flat panel inspection instrument. The connecting groove allows for the fitting onto the outside of the connecting strip, thus fixing the two fixing seats. The fixing knob facilitates the fixing of the connecting strip inserted into the connecting groove, thus securing the two fixing seats together.

[0005] Although the patent makes it easy to fix the connecting strip inserted into the connecting groove by setting a fixed knob, thereby fixing the two fixed seats, the method of limiting the plate detector to the pipeline equipment by binding straps is relatively limited in use during installation. This is because the binding strap material is not easily deformed, which also means it is not easy to stretch. When using it with different types and formats of pipeline equipment, different lengths of binding straps need to be changed, and the installation and disassembly process is cumbersome, resulting in poor performance. Utility Model Content

[0006] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a fixing device for a digital X-ray inspection instrument for pressure pipelines. The technical problem to be solved by this utility model is: how to improve the connection effect between the instrument and pipeline equipment through adsorption fixing, and how to fix it to the inner and outer walls of the pipeline, with a wide fixing range and strong adaptability.

[0007] The objective of this utility model can be achieved through the following technical solutions:

[0008] A mounting device for a digital X-ray inspection instrument for pressure pipelines includes a mounting frame and a pair of adsorption cylinders rotatably connected to the mounting frame. Each of the two adsorption cylinders contains an adsorption fixing component, and an instrument mounting plate is fixed to the mounting frame. The mounting frame contains a control component for controlling the operation of the adsorption fixing components, and an adjustment component for controlling the angle adjustment of the two adsorption cylinders. The adjustment component includes a pair of adjusting worm gears rotatably connected to the mounting frame and a pair of adjusting worms rotatably connected to the mounting frame. Both adjusting worm gears are coaxially fixedly connected to their corresponding adsorption cylinders, and the two adjusting worms mesh with their corresponding adjusting worm gears.

[0009] The working principle of this utility model is as follows: the two adsorption cylinders can be adjusted according to the curvature of the inner or outer wall of the pressure pipe by adjusting the component, so as to better connect and fix the adsorption fixing component with the pressure pipe and improve the adsorption fixing effect. Then, the adsorption fixing component is controlled by the regulating component to perform the adsorption fixing action, thereby improving the overall operation efficiency, making it easier for personnel to operate and improving the ease of operation.

[0010] The control assembly includes a main drive worm gear rotatably connected within the fixed frame and two transmission worm wheels rotatably connected within the fixed frame. Each of the two transmission worm wheels is coaxially and fixedly connected to a winding wheel. One end of a traction rope is fixedly connected to each of the two winding wheels. The other end of each traction rope is connected to a corresponding adsorption and fixing assembly. An adjustment wheel is provided outside the fixed frame, and the adjustment wheel is coaxially and fixedly connected to the main drive worm gear.

[0011] With the above structure, the main drive worm gear can be rotated by the control wheel. After the main drive worm gear rotates, it will drive the two transmission worm gears to rotate. After the two transmission worm gears rotate, they will drive the two winding wheels to rotate. After the winding wheels rotate, they will wind up or release the traction rope and connect it to the adsorption fixing component through the traction rope, thereby realizing the ability to control the adsorption state of the adsorption fixing component.

[0012] The adsorption fixing assembly includes two adsorption cylinders with suction grooves inside, and pistons slidably connected in both suction grooves. The bottom of each adsorption cylinder has a suction hole that communicates with the corresponding suction groove. A return spring is fixed between each piston and the bottom of the corresponding suction groove. The other ends of the corresponding traction ropes of the two pistons are fixedly connected.

[0013] With the above structure, the piston can be pulled when the traction rope is wound up, causing the piston to move and draw air through the suction hole. This creates a negative pressure at the contact point between the suction hole and the pressure pipe, forming an adsorption force, thereby achieving the ability to adsorb and fix. When the traction rope is released, the return spring loses its restraint and pushes the piston back to its original position, expelling the drawn-in air and invalidating the negative pressure state, thus facilitating disassembly and improving the overall fixing efficiency.

[0014] Both adsorption cylinders have sealing gaskets fixed at their bottoms, surrounding the corresponding suction holes.

[0015] With the above structure, the contact point between the gasket and the pressure pipeline can be sealed to ensure stable negative pressure suction.

[0016] The fixed frame is equipped with a pair of adjusting torsion wheels, and the two adjusting torsion wheels are coaxially fixedly connected to the corresponding adjusting worm gear.

[0017] With the above structure, the rotation of the adjusting worm gear can be made more convenient by adjusting the torsion wheel, thereby further facilitating the adjustment of the angle of the two adsorption cylinders.

[0018] Compared with existing technologies, this digital X-ray inspection instrument fixing device for pressure pipelines has the following advantages:

[0019] 1. By adjusting the components, the two adsorption cylinders are adjusted at corresponding angles according to the curvature of the inner or outer wall of the pressure pipe, so as to better connect and fix the adsorption fixing components with the pressure pipe and improve the adsorption fixing effect.

[0020] 2. When the traction rope is wound up, it pulls the piston, causing the piston to move and draw air through the suction hole. This creates a negative pressure at the contact point between the suction hole and the pressure pipe, forming an adsorption force, thus achieving the ability to adsorb and fix. When the traction rope is released, the return spring loses its restraint and pushes the piston back to its original position, expelling the drawn-in air and dissolving the negative pressure state, thereby facilitating disassembly and improving the overall fixing efficiency.

[0026] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0027] like Figures 1-4 As shown, a fixing device for a digital X-ray inspection instrument for pressure pipelines includes a fixing frame 1 and a pair of adsorption cylinders 2 rotatably connected to the fixing frame 1. Each adsorption cylinder 2 is provided with an adsorption fixing component, and an instrument mounting plate 3 is fixed on the fixing frame 1. The fixing frame 1 is provided with a control component for controlling the operation of the adsorption fixing component, and an adjustment component for controlling the angle adjustment of the two adsorption cylinders 2 is provided in the fixing frame 1. The adjustment component includes a pair of adjusting worm gears 4 rotatably connected to the fixing frame 1 and a pair of adjusting worms 5 rotatably connected to the fixing frame 1. Both adjusting worm gears 4 are coaxially fixedly connected to the corresponding adsorption cylinders 2, and the two adjusting worms 5 mesh with the corresponding adjusting worm gears 4.

[0028] The two adsorption cylinders 2 can be adjusted at corresponding angles according to the curvature of the inner or outer wall of the pressure pipe by adjusting the component, so as to better connect and fix the adsorption fixing component with the pressure pipe and improve the adsorption fixing effect. Furthermore, the adsorption fixing component can be controlled by the regulating component to perform the adsorption fixing action, thereby improving the overall operation efficiency, making it easier for personnel to operate, and improving the convenience of operation.

[0029] The control assembly includes a main drive worm gear 6 rotatably connected within the fixed frame 1, and two transmission worm wheels 7 rotatably connected within the fixed frame 1. Both transmission worm wheels 7 are coaxially fixedly connected to a winding wheel 8. One end of a traction rope 9 is fixedly connected to each of the two winding wheels 8. The other end of each traction rope 9 is connected to a corresponding adsorption fixing assembly. An adjustment wheel 10 is provided outside the fixed frame 1, and the adjustment wheel 10 is coaxially fixedly connected to the main drive worm gear 6.

[0030] With the above structure, the main drive worm gear can be rotated by the regulating wheel 10. After the main drive worm gear rotates, it will drive the two transmission worm gears 7 to rotate. After the two transmission worm gears 7 rotate, they will drive the two winding wheels 8 to rotate. After the winding wheels 8 rotate, they will wind up or release the traction rope 9 and connect it to the adsorption fixing component through the traction rope 9, thereby realizing the ability to control the adsorption state of the adsorption fixing component.

[0031] The adsorption fixing assembly includes two adsorption cylinders 2 with suction grooves 11 inside, and pistons 12 slidably connected in both suction grooves 11. The bottom of each adsorption cylinder 2 has a suction hole 13 that communicates with the corresponding suction groove 11. A return spring 14 is fixed between each piston 12 and the bottom of the corresponding suction groove 11. The other end of the traction rope 9 corresponding to the two pistons 12 is fixedly connected.

[0032] With the above structure, when the traction rope 9 is wound up, it pulls the piston 12, causing the piston 12 to move and draw air through the suction hole 13. This creates a negative pressure at the contact point between the suction hole 13 and the pressure pipe, forming an adsorption force, thereby achieving the ability to adsorb and fix. When the traction rope 9 is released, the return spring 14 loses its restraint and pushes the piston 12 back to its original position, expelling the drawn air and making the negative pressure state invalid. This facilitates disassembly and improves the overall fixing efficiency.

[0033] Both adsorption cylinders 2 have sealing gaskets 15 fixed at their bottoms, surrounding the corresponding suction holes 13.

[0034] With the above structure, the sealing gasket 15 can be used to seal the joint with the pressure pipeline, thus stably achieving the operation of suction negative pressure.

[0035] A pair of adjusting torsion wheels 16 are provided on the fixed frame 1, and the two adjusting torsion wheels 16 are coaxially fixedly connected to the corresponding adjusting worm gear 5.

[0036] With the above structure, the rotation of the adjusting worm gear 5 can be made more convenient by adjusting the torsion wheel 16, thereby making it easier for personnel to adjust the angle of the two adsorption cylinders 2.

[0037] The working principle of this utility model is as follows: The digital X-ray instrument is fixed to the instrument mounting plate 3 by screw fastening or external surface pressing. Then, according to the curvature of the inner or outer wall of the pressure pipe, the adjusting torsion wheel 16 drives the corresponding adjusting worm 5 to rotate. The rotation of the adjusting worm 5 drives the corresponding adjusting worm wheel 4 to rotate, which in turn drives the corresponding adsorption cylinder 2 to rotate, thus adjusting the angle and better connecting the inner or outer wall of the pressure pipe. The adjusting wheel 10 drives the main drive worm wheel to rotate, which in turn drives the adsorption cylinder 2 to rotate. Two drive worm gears 7 rotate, which in turn drives two winding wheels 8 to rotate. The winding wheels 8 then wind up the traction rope 9. As the traction rope 9 winds up, it pulls the piston 12, causing the piston 12 to move and draw air through the suction hole 13. This creates a negative pressure at the contact point between the suction hole 13 and the pressure pipe, forming an adsorption force, thus achieving the ability to adsorb and fix the object. When the winding wheel 8 rotates in the opposite direction to release the traction rope 9, the return spring 14 loses its restraint and pushes the piston 12 back to its original position, expelling the drawn-out air and dissolving the negative pressure state. This facilitates disassembly and improves the overall fixing efficiency.

[0038] In summary, by adjusting the components to control the two adsorption cylinders 2 to adjust their angles according to the curvature of the inner or outer wall of the pressure pipe, the adsorption fixing components can be better connected and fixed to the pressure pipe, thereby improving the adsorption fixing effect. Furthermore, by controlling the adsorption fixing components to perform adsorption fixing actions, the overall operating efficiency can be improved, making it easier for personnel to operate and enhancing the convenience of operation.
