Description

Technical Field

[0001] This application relates to the field of flaw detection equipment technology, and specifically discloses a transmission structure for an X-ray gate. Background Technology

[0002] X-ray doors are used in X-ray flaw detection rooms, which are widely used in boiler, petrochemical and other fields, mainly for non-destructive testing of workpiece welds. X-ray flaw detection rooms are generally constructed of concrete and use lead doors for protection and opening / closing.

[0003] As shown in the accompanying drawings of this application specification. Figure 1 The diagram illustrates the transmission structure of an X-ray door. Two hooks are fixedly installed at the top of the left and right sides of the X-ray door. Each hook has a rotatable roller with a rim mounted on its top. A motor is installed on the right hook to drive the roller on the same side. Simultaneously, a fixed component and a slide rail extend from the wall of the X-ray inspection room. Driven by the motor, the X-ray door moves along the slide rail via the rollers, thus locking the X-ray door. Furthermore, to ensure accurate positioning of the X-ray door and prevent X-ray leakage, two more rotatable rollers are installed on the lower side of the X-ray door. A steel rail is installed on the floor of the X-ray inspection room for the rollers to travel on.

[0004] While the above structure fulfills the functions of X-ray door movement and protection, it is only suitable for cases where tracks are laid inside the X-ray inspection room and conveyor rollers are laid outside. If tracks are laid both inside and outside the X-ray inspection room, there is a possibility that the tracks may be damaged during the opening and closing of the X-ray door when passing through the room, creating a 50-100mm gap that prevents the X-ray inspection vehicle from passing through.

[0005] This invention provides a transmission structure for an X-ray gate to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of this invention is to solve the problem that when a traditional X-ray gate travels on a track that spans both indoors and outdoors, the track may break, preventing the X-ray inspection vehicle from passing through the broken section.

[0007] To achieve the above objectives, the basic solution of this utility model provides a transmission structure for an X-ray door, including ear hooks fixed to both sides of the top of the X-ray door, roller 1 rotatably connected to the ear hooks, roller 2 rotatably connected to both sides of the bottom of the X-ray door, a slide rail fixed to the wall of the X-ray inspection room for the rollers to move, and a steel rail fixed to the floor of the X-ray inspection room for the roller 2 to move. It also includes a steel plate on the floor of the X-ray inspection room and flush with the height of the steel rail, a roller bracket fixed to the bottom side of the X-ray door, and a drive mechanism in the X-ray inspection room for moving the X-ray door. The roller 2 is rotatably connected to the roller bracket, the bottom end of the roller 2 is flush with the lower surface of the X-ray door, and the width of the steel plate is not less than the width of the X-ray door.

[0008] Furthermore, the width of the steel plate is equal to the width of the X-ray gate.

[0009] Furthermore, the roller bracket includes an L-shaped bracket fixed to the bottom side of the X-ray gate, vertical connecting plates fixed to both sides of the L-shaped bracket, and a rotating rod two rotatably connected between the vertical connecting plates on both sides for mounting the roller two.

[0010] Furthermore, a rotating rod is rotatably connected inside the ear hook, and the roller is coaxially fixed to the rotating rod.

[0011] Furthermore, it also includes several fixed platforms within the X-ray flaw detection room that support the steel plate concrete foundation.

[0012] Furthermore, the concrete foundation platform is fixed to the indoor floor of the X-ray flaw detection room at both ends and the middle of the rail.

[0013] Furthermore, the drive mechanism includes a rack fixed to one side of the X-ray gate, a drive motor located in the X-ray flaw detection chamber, and a gear transmission mechanism located between the output shaft of the drive motor and the rack.

[0014] The principle and effect of this solution are as follows:

[0015] Compared with the prior art, this utility model uses the output shaft of the drive motor to rotate and drive the rack through the gear transmission mechanism, which in turn drives the X-ray door to slide along the slide rail. During this process, the steel plate and the steel rail form an integral surface, so that the roller two is always in contact with the integral surface formed by the steel plate and the steel rail during the journey, preventing the steel rail from being broken by the lead door. This solves the problem that when the traditional X-ray door travels on the track that spans the indoor and outdoor areas, the track will be broken, causing the X-ray inspection vehicle to be unable to pass when it reaches the broken position.

[0021] The reference numerals in the accompanying drawings include: drive motor 1, X-ray gate 2, roller one 3, slide rail 4, steel rail 5, straight rack 6, steel plate 7, roller two 8, concrete foundation platform 9.

[0022] A transmission structure for an X-ray gate, implementing, for example... Figure 2 As shown:

[0023] This includes ear hooks welded to the left and right sides of the top of the X-ray gate 2, and roller brackets welded to the left and right sides of the bottom of the X-ray gate 2. Rotatable roller 3 and roller 2 are respectively installed via the ear hooks and roller brackets.

[0024] Specifically, each ear hook is equipped with a rotatable rotating rod, and roller 3 is coaxially fixedly installed on the rotating rod. The roller bracket is welded to the L-shaped bracket on the bottom side of the X-ray gate 2, vertical connecting plates are welded to both sides of the L-shaped bracket, and a rotating rod 2 is installed between the two vertical connecting plates and is rotatable. Roller 2 8 is coaxially fixedly installed on the rotating rod 2.

[0025] The transmission structure also includes a slide rail 4 bolted to the wall of the X-ray flaw detection room and a steel rail 5 bolted to the floor of the X-ray flaw detection room. The roller 3 is mounted on the slide rail 4 and slides along the slide rail 4.

[0026] In this embodiment, the transmission mechanism also includes a steel plate 7 installed on the floor of the X-ray flaw detection room and a drive mechanism installed inside the X-ray flaw detection room for driving the X-ray door 2 to move.

[0027] Specifically, the X-ray flaw detection chamber has several concrete foundation platforms 9 cast inside, which support the steel plate 7, ensuring that the height of the steel plate 7 is flush with the height of the steel rail 5. The concrete foundation platforms 9 are cast on the floor of the X-ray flaw detection chamber at both ends and the middle of the steel rail 5. Furthermore, the width of the steel plate 7 is equal to the width of the X-ray door 2; in other embodiments, the width of the steel plate 7 is required to be no less than the width of the X-ray door 2.

[0028] Furthermore, the bottom end of roller 28 is flush with the lower surface of X-ray gate 2.

[0029] like Figure 2 As shown, the drive mechanism includes a rack 6 horizontally fixed to the X-ray gate 2, a drive motor 1 fixed in the X-ray inspection chamber, and a gear transmission mechanism installed between the output shaft of the drive motor 1 and the rack 6. The gear transmission mechanism here is a commonly used gear set transmission mechanism in the prior art.

[0030] When this utility model is in use, the output shaft of the drive motor 1 rotates and drives the rack 6 through the gear transmission mechanism, which drives the X-ray door 2 to slide along the slide rail 4. During this process, the steel plate 7 and the steel rail 5 form an integral surface, so that the roller 2 is always in contact with the integral surface formed by the steel plate 7 and the steel rail 5 during the travel, preventing the steel rail 5 from being broken by the lead door.

[0031] Meanwhile, the X-ray gate 2 is driven by the rack and pinion 6, which makes the movement of the X-ray gate 2 more stable.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
