The track consists of a large arc track A, two sections of transition arc tracks B and a linear track C. When the treatment head rotates, the length of the occupied track also changes, so that the length of the chain floor also needs to change so as to prevent the track from being empty.
The current proton heavy ion rotating floor generally comprises an upper layer track and a lower layer track, wherein the upper layer track is driven by a treatment head, the lower layer track is driven by a frame, and the length change of the chained floor in the rotating process of the treatment head is compensated through dislocation of the two tracks. The publication number CN 114042261A discloses a rotary floor, which relates to a rotary floor integral structure, wherein a chained floor is a single-layer track, and the stretching and the retraction of the whole chained floor are realized through waist-shaped holes on a supporting traction chain.

As shown in fig. 2 to 4, a telescopic chain type rotating floor 3 for a rotating frame according to an embodiment of the present disclosure includes: a front rail 31, a rear rail 32, a support bar 33, a flexible floor sheet 35 and a hard rubber link 34. Wherein, the front rail 31 is installed on the wall surface fixing component 1, and the wall surface fixing component 1 is fixed on the civil engineering foundation of the treatment room; a rear rail 32 disposed inside the cylinder of the rotating frame, connected to the rear end assembly 2 inside the rotating frame, and parallel to the front rail 31; the rear end component 2 is arranged inside the rotary rack barrel, and the rear end is kept horizontal when the rotary rack rotates; the two ends of the supporting rods 33 are slidably arranged on the front rail 31 and the rear rail 32, and two adjacent supporting rods 33 are connected through a hard rubber connecting piece 34; a plurality of flexible floor pieces 35, each flexible floor piece 35 being provided on two adjacent support rods 33.
As shown in fig. 2 and 3, in the present embodiment, the front rail 31 and the rear rail 32 include an arc section a, a transition arc section B and a straight line section C, the transition arc section B is disposed at the junction of the arc section a and the straight line section C, and the radius of the transition arc section B is smaller than that of the arc section a. The plurality of flexible floor pieces 35 are laid to have a total length smaller than that of the front rail 31 and the rear rail 32, and a notched area is formed on the front rail 31 and the rear rail 32; the treatment head protective housing 4 is arranged in the gap area. The length of the treatment head protective housing 4 is greater than the tangential length of the transition arc segment B.
Further, the treatment head protective housing 4 is connected to a flexible floor sheet 35, and the flexible floor sheet 35 has flexibility. When the treatment head protective shell 4 rotates, the telescopic chained rotary floor 3 is driven to rotate together, and the difference of the total track length under different angles of the treatment head is compensated by virtue of the telescopic performance of the flexible floor sheet 35.
As shown in fig. 4, in the present embodiment, both ends of the hard rubber coupling member 34 are provided with small holes for nesting two adjacent support rods 33. The number of hard rubber connectors 34 that are sleeved on the two support rods 33 in the drawing is merely illustrative, and is not limited in this regard. The front surface of the flexible floor sheet 35 faces the inside of the annular region constituted by the front rail 31 and the rear rail 32. The hard rubber link 34 is provided on the back surface of the flexible floor sheet 35.
As shown in fig. 5, in the present embodiment, rollers 331 are provided at both ends of the support bar 33, which are engaged with guide rail tracks of the front rail 31 and the rear rail 32, to assist the telescopic chain type rotating floor 3 to slide along the rails.
In the present embodiment, the back surface of the flexible floor sheet 35 is provided with a buckle 351 and/or a hook 352, and the flexible floor sheet 35 is caught on the adjacent two support rods 33. The back of each flexible floor sheet 35 may be provided with a plurality of sets of snaps 351 or hooks 352, or a combination of a plurality of sets of snaps 351 and hooks 352. As shown in fig. 6, a circular buckle 351 and a waist-shaped hook 352 are provided at the bottom of the flexible floor sheet 35, and when the flexible floor sheet is installed, the waist-shaped hook 352 is hooked on one support rod 33, and then the circular buckle 351 is buckled on the adjacent second support rod 33.
The flexible floor sheet 35 is a material having a certain flexibility, and can be bent and elongated to a certain extent to ensure that the flexible floor sheet 35 can smoothly pass through the transition arc section B of the track.
The telescopic chain type rotating floor for a rotating frame provided by the present disclosure is described below by way of a specific embodiment.
In one example, as in fig. 1, the dimensions of the track are r=1960 mm, r=600 mm, l=1200 mm, and the treatment head width is 1000mm. The total track length was calculated to be about 11722mm. When the treatment head occupies one transition circular arc track B and the rest of the track belongs to the straight line track C, namely the angle of the treatment head is about 132.7 °, the length of the track occupied by the treatment head is longest, and at the moment, the length of the telescopic chain type rotating floor 3 is shortest, and the length is 10489mm. When the treatment head rotates to the center of the straight track C, namely the angle of the treatment head is 180 degrees, the length of the track occupied by the treatment head is shortest, and the length of the telescopic chain type rotary floor 3 is longest, and the length is 10722mm. Therefore, the expansion and contraction amount of the whole expansion and contraction chain type rotary floor 3 is 233mm. The distance between the supporting rods 33 is 50mm, the number of the supporting rods 33 is 210, so that the expansion and contraction amount 233mm of the whole expansion and contraction chain type rotating floor 3 is distributed to each hard rubber connecting piece 34 to be about 1mm, the number of the flexible floor pieces 35 is 70, the space between the 3 supporting rods 33 below the flexible floor pieces 35 can be digested due to the elasticity of the flexible floor pieces 35, and the maximum gap between the flexible floor pieces 35 is only 1mm when the whole expansion and contraction chain type rotating floor 3 is stretched to the longest position.
The support rod interval that the telescopic chain type swivel floor for swivel mount provided by this disclosed embodiment is little, arranges more densely, and single hard rubber connecting piece flexible deformation is little, and the gap between floor piece and floor piece is very little. The structure is simple, the disassembly and the assembly are convenient, and the supporting rod and the flexible floor sheet can be quickly replaced. The telescopic chain type rotating floor member has high overall independence and has simpler interfaces with other peripheral members and devices; meanwhile, the floor has small section thickness due to the single-layer track, and has less interference with adjacent equipment. These significantly reduce the amount of effort in the design of the rotating gantry system integration. The telescopic chain type rotary floor has wide applicability and can be applied to various proton heavy ion projects with different floor widths and different frame inner diameters by slightly modifying the size.
Those skilled in the art will appreciate that the features recited in the various embodiments of the disclosure and/or in the claims may be provided in a variety of combinations and/or combinations, even if such combinations or combinations are not explicitly recited in the disclosure.
