Description

Technical Field

[0001] The utility model relates to the technical field of industrial metal non-destructive testing, and specifically relates to a track movable connection device for a horizontal vehicle in a ray exposure room. Background Art

[0002] Shielding protection requires the construction of a radiographic inspection room (consisting of an exposure room and an operating room). Workpieces are transported to the exposure room for inspection by a horizontal vehicle. Due to the large transport capacity of the exposure room's horizontal vehicle, it must operate on rails, moving from inside the exposure room to outside, and transporting the workpieces back and forth. Furthermore, before X-ray exposure, the exposure room's shielding door must be closed to prevent radiation from reaching outside the room and potentially harming personnel. Because the shielding door is large, it operates on separate tracks, opening and closing the door.

[0003] To meet protection requirements and prevent radiation from escaping through the gaps below the shielding doors, exposure rooms typically require manual disassembly and removal of the track. This increases the number of steps and mechanical failures, as well as the operator's workload. Forgetting to connect the track poses a significant safety hazard. Therefore, we propose a removable track connection device for the track in radiation exposure rooms to provide effective protection. Utility Model Content

[0004] The purpose of the utility model is to provide a track movable connection device for a floor vehicle in a ray exposure room, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a movable connection device for a floor car track in a X-ray exposure room, comprising a base plate, the upper surface of which is symmetrically and fixedly connected to a second double track, and the second double track is vertically symmetrically arranged, the inner side wall of the base plate is provided with a sliding track structure, the upper surface of the base plate is fixedly connected to a shielding door frame, the inner cavity of the shielding door frame is installed with a shielding door panel, the side wall of the shielding door panel is fixedly connected to a through-hole plate, the lower surface of the through-hole plate is in contact with the upper surface of the sliding track structure, and the through-hole plate is fixedly connected to the sliding track structure by bolts.

[0006] Preferably, the sliding track structure includes an inner track, both ends of the inner track are fixedly connected to the inner side wall of the bottom plate, the outer wall of the inner track is sleeved with a support plate, the lower surface of the support plate is symmetrically fixedly connected with rollers, the side walls of the support plate are in contact with the inner side wall of the bottom plate, the center of the upper surface of the support plate is fixedly connected with a first double track, the two ends of the first double track are in contact with the end parts of the second double track, the upper surface of the support plate is in contact with the lower surface of the through-hole plate, and the through-hole plate is fixedly connected to the support plate by bolts.

[0007] Compared with the prior art, the beneficial effects of the present invention are: when performing shielding protection work, through the cooperation of the bottom plate and the sliding track structure, when the shielding door is completely opened, the sliding track structure connected to the shielding door panel moves together, and the first double track on the surface of the sliding track structure is just connected to the track disconnection point of the second double track. When the shielding door is closed, the power of the door is used to push the sliding track structure open, so that it is stored in the inner cavity of the through groove of the bottom plate, and the second double track is disconnected, so that the door is smoothly closed. There is no need to manually disassemble the track. The track assembly is completed when the shielding door switch is closed, which reduces the operating intensity of the staff, avoids multiple disassembly that may easily cause damage to the equipment, ensures the safe operation of the leveling vehicle and the shielding door, and eliminates safety hazards.

The upper surface of the support plate 22 is in contact with the lower surface of the through-hole plate 6, and the through-hole plate 6 is fixedly connected to the support plate 22 by bolts.

[0016] Working principle: Before carrying out the shielding protection work, a base plate 1 is set at the door of the radiographic inspection room in advance. The base plate 1 is a pre-buried casting setting, which is fully combined with the ground of the radiographic inspection room. At the same time, a second double track 3 is symmetrically set on both sides of the base plate 1, and the second double track 3 on both sides is disconnected. A rectangular through groove is set at the disconnection, and a sliding track structure 2 is set at the through groove. Then, a shielding door frame 4 is installed on the surface of the base plate 1. The shielding door frame 4 is installed on the top of the through groove of the base plate 1. The shielding door frame 4 and the shielding door panel 5 form a complete shielding door. A through-hole plate 6 is fixed on one side of the shielding door panel 5. The bottom of the through-hole plate 6 fits with the upper surface of the sliding track structure 2 and is connected and fixed to one side of the shielding door panel 5 by bolts. In addition, a plurality of sets of side-by-side screw holes are provided on the surface of the support plate 22 of the sliding track structure 2, which can be fixed according to the track so that the distance at one end can be adjusted to ensure the The first double track 23 and the second double track 3 are combined to form a straight line. When the shielding door is working, the shielding door panel 5 will slide between the door openings of the shielding door frame 4 using the power of the shielding door switch, and at the same time pull the sliding track structure 2. The center of the support plate 22 is sleeved with the inner track 21, and the two ends of the inner track 21 are fixed to the through groove of the bottom plate 1. At the same time, the bottom of the support plate 22 is provided with rollers 24, which slide along the through groove ground. When the shielding door is completely opened, the first double track 23 on the surface of the support plate 22 is just connected to the track disconnection point of the second double track 3. When the shielding door is closed, the power of the door is used to push the branch plate 22 to disconnect the second double track 3, so that the door can be closed smoothly. There is no need to manually disassemble the track. The track assembly is completed when the shielding door switch is closed, avoiding the increase of operation links. Repeated disassembly is prone to mechanical failure and reduces the operating intensity of the staff.
