Fig. 2A and 2B are schematic front views of a cable winder for an accelerator according to an embodiment of the present invention before and after a cable is disposed. Referring to fig. 1A, 1B, 2A and 2B, the wire winder 101 is installed inside a housing 1011 of an accelerator, a wire-feeding guide wire 103 is fixedly provided on a radially outer layer of a housing drum 102 of the accelerator with respect to the housing 1011 of the accelerator, a wire winder 104 is provided on a radially inner layer of the housing drum 102 around the wire winder 101, the wire-feeding guide wire 103 and the wire winder 104 are connected by a suspension wire 105, and the wire winder 104 follows the wire winder 101 to wind when the wire winder 101 rotates, so that the suspension wire 105 exits or retracts into the wire winder 101.
In practical applications, for example, the wire coiler 101 may be fixedly disposed on the sprocket 106 of the accelerator by using a fixing member such as a nut, and thus the wire coiler 101 may rotate following the rotation of the gantry drum 102. The wire coil cable 104 may be fixed to the wire coil 101 by a fixing means. Optionally, an incoming line support plate 107 is disposed between the incoming line guide cable 103 and the coiled line cable 104. The inlet wire supporting plate 107 is fixedly provided with a supporting plate fixing lug 108, and the inlet wire supporting plate 107 can be fixedly connected with the rack 1011 through the supporting plate fixing lug 108 and holes on the rack 1011 of the accelerator. Specifically, for example, the inlet support plate 107 may be integrally formed with the support plate fixing tab 108, or the inlet support plate 107 may be fixedly connected with the support plate fixing tab 108. The housing 1011 has a hole 109. The support plate fixing tabs 108 may then be fixed at the holes 109 by fasteners such as nuts or pins, thereby fixedly connecting the inlet support plate 107 to the frame 1011 of the accelerator.
The presence of three support plate securing tabs 108 (one above the puck 101, one to the left of the puck 101, and one to the right of the puck 101) is shown in fig. 1B and 2B, respectively, it being understood that the number and location of the support plate securing tabs 108 is not limited thereto, and the support plate securing tabs 108 can have any suitable number and be disposed at suitable locations, so long as the support plate securing tabs 108 enable the inlet support plate 107 to be secured relative to the frame 1011 of the accelerator.
Optionally, the inlet support plate 107 comprises an inlet support plate 1071 located at the inlet end 120 of the inlet guide cable 103, the inlet support plate 1071 having a predetermined angle with respect to the frame 1011, the inlet support plate 1071 being adapted to support the inlet end 120 of the inlet guide cable 103 such that the inlet end 120 of the inlet guide cable 103 is fed at said predetermined angle. In particular, the inlet support plate 107 may extend down to the inlet end 120 of the inlet guide cable 103 to form an inlet support plate 1071 for supporting the inlet end 120 of the inlet guide cable 103. Likewise, the incoming support plate 107 may also comprise an entrance support plate located at the entrance end 140 of the incoming guide cable 103.
The pendant cable 105 is, for example, a bent pendant cable that can be extended and retracted by withdrawing and retracting the winder 101. Specifically, as shown in fig. 2B, the catenary cable 105 may include a first section 1051 directly connected to the incoming guide cable 103, a second section 1052 directly connected to the wire coil cable 104, and an intermediate section connecting the first and second sections 1051, 1052, which naturally sags below the wire coil 101 due to gravity.
In practical applications, the incoming guide cable 103, the messenger cable 105 and the spooled cable 104 may be different parts of the same cable (parts located at different positions with respect to the spooler 101). The inlet end 120 of the incoming guide cable 103 is connected with the cable outside the accelerator, the incoming guide cable 103 is fixedly arranged on the incoming support plate 107, the other end of the incoming guide cable 103 far from the inlet end 120 is connected with the first section 1051 of the suspension cable 105, the first section 1051 is connected with the second section 1052 through the middle section, the second section 1052 is connected with the wire coiling cable 104, and the wire coiling cable 104 is fixedly wound on the wire coiling device 101. The wire coiling cable 104 is wound along with the rotation of the wire coiling device, so as to drive the suspension wire 105 (for example, the second section 1052) to exit or enter the wire coiling device 101, when the suspension wire 105 exits the wire coiling device 101, the length of the second section 1052 in the suspension state is increased, and the position of the middle section is lowered; when the suspended cable 105 is taken up into the reel 101, the length of the second section 1052 in the suspended state is reduced, and the position of the intermediate section is raised, that is, the telescopic function of the suspended cable 105 is realized.
By disposing the winder 101 and the incoming guide mechanism (e.g., incoming guide cable 103) inside the housing 1011, the incoming guide cable 103, the catenary cable 105, and the winding cable 104 are divided into two layers as viewed from the radial direction of rotation of the housing drum 102 by the space inside the housing 1011. The wire coiling cable 104 is on the inlayer, and the cable is convoluteed around the wire coiler 101, and the skin is inlet wire direction cable 103, and the radius of curvature of inlet wire direction cable 103 is greater than the cable radius of curvature on the inlayer wire coiler 101, is favorable to the transport of inlet wire direction cable 103, and the cable 105 that dangles is the connecting cable of inlayer cable and outer cable, can send the cable to the wire coiler 101 convoluteing, also can follow the wire coiler 101 and convolute and withdraw from the cable, as above, the cable 105 that dangles is one section can extend and the crooked cable that hangs down that shortens.
In summary, the wire winder for the accelerator provided by the invention is installed inside a rack of the accelerator, the wire inlet guide cable is fixedly arranged on the radial outer layer of a rack drum of the accelerator relative to the rack of the accelerator, the wire winding cable is arranged on the radial inner layer of the rack drum, the wire inlet guide cable is connected with the wire winding cable through the suspension cable, and when the wire winder rotates, the wire winding cable winds along with the wire winder, so that the suspension cable exits or retracts into the wire winder. Because the radius of curvature of the outer incoming line guide cable is larger than the radius of curvature of the upper coiling cable of the inner coiling device, the incoming line guide cable is conveyed and the overhanging cable is wound and unwound, and meanwhile, the coiling device and the incoming line guide cable are arranged inside the rack, the whole transportation size of the accelerator is reduced, and the whole accelerator can conveniently enter a machine room for placing the accelerator through a bending channel.
Alternatively, the incoming guide cable 103 includes a first incoming guide cable and a second incoming guide cable, the pendant cable 105 includes a first pendant cable and a second pendant cable, the coiled cable 104 includes a first coiled cable and a second coiled cable, the first incoming guide cable is connected to the first coiled cable by the first pendant cable, the second incoming guide cable is connected to the second coiled cable by the second pendant cable, a first group of cables is formed by the first incoming guide cable, the first pendant cable and the first coiled cable, a second group of cables is formed by the second incoming guide cable, the second pendant cable and the second coiled cable, the first group of cables and the second group of cables are arranged side by side in the axial direction of the rack, the first group of cables is incoming from the left side of the rack, and the second group of cables is incoming from the right side of the rack. That is, referring to fig. 3A and 3B, two sets of cables are arranged side by side in the axial direction of the rack drum 102 on the line winder 101 of the accelerator, the constituent parts and arrangement of each set of cables being similar to those described with reference to fig. 1A to 2B, but the difference being that the incoming directions of the two sets of cables are different from each other and the winding directions are opposite to each other. For example, a first set of cables may be fed from the left side of the rack 1011 (the incoming line end is the entry end 140 shown in FIG. 2B. the first drop cable is the drop cable 150 shown in FIG. 2B (including the first section 1501 and the second section 1502)), and a second set of cables may be fed from the right side of the rack 1011 (the incoming line end is the entry end 120 shown in FIG. 2B).
As shown in fig. 3B, the second incoming guide cable may be the incoming guide cable 103 and the first messenger may be the messenger 150. It should be understood that each of the first and second sets of cables may include a plurality of cables arranged in parallel, as shown in fig. 3B.
The first wire coiling cable and the second wire coiling cable can be fixed on the wire coiling device through fixing devices respectively. When the winder 101 rotates clockwise, the wire winding cable winds clockwise following the winder 101, and the first catenary cable is drawn into the winder 101, and the second catenary cable is drawn out of the winder 101 due to the opposite winding direction of the first group cable and the second group cable. Accordingly, when the winder 101 rotates counterclockwise, the wire winder cable winds counterclockwise following the winder 101, the second catenary cable is taken up into the winder, and the first catenary cable is taken out of the winder.
That is, the incoming guide cable 103, the catenary cable 105, and the wire-coiling cable 104 shown in fig. 1A to 2B may be divided into two layers along the axial direction of the rack drum 102, one layer being incoming from the right side of the rack, passing through the incoming guide cable, the catenary cable, and the wire-coiling cable into the inside of the rack, and the other layer being incoming from the left side of the rack, passing through the incoming guide cable, the catenary cable, and the wire-coiling cable into the inside of the rack. The cables are subjected to factors such as gravity, the take-in and take-out reels, and the load (stress) on the rack drum 102 is not the same. For single-side incoming, if the wire coiling device retracts along the rotating cable of the pointer, the load of the rack rotating drum 102 is increased, when the wire coiling device rotates anticlockwise, the cable withdraws, at the moment, the load of the rack rotating drum 102 is reduced, when the rack rotating drum 102 rotates anticlockwise or clockwise, the transmission system of the rack is always in an unbalanced stress state, the alternating load is unfavorable for the transmission system of the rack, and the service life of a transmission part is shortened. The two-side incoming line provided by the embodiment of the invention has the advantages that: no matter the rack rotating drum 102 rotates clockwise or anticlockwise, the load of the rack rotating drum 102 is relatively balanced, so that the transmission is more stable, and the service life of a transmission part is longer.
In summary, in the wire winder structure provided by the embodiment of the present invention, the bending radius of the outer wire-incoming guide cable is larger than the bending radius of the cable on the inner wire winder, which is beneficial to the transmission of the wire-incoming guide cable and the winding and unwinding of the suspended cable. No matter the frame is clockwise or anticlockwise rotatory, the loading of left and right two-layer cable to the motor is the same, can solve the unbalanced state that frame positive and negative rotation, unilateral inlet wire cable produced. Meanwhile, the wire coiling device is arranged in the machine room, and the space is partially vacated, so that the whole transportation size of the accelerator is reduced, and the whole accelerator can conveniently enter the machine room for placing the accelerator through the bent channel. In addition, the cables are arranged into two rows which are arranged side by side along the axial direction of the rack, and high and low voltage wires can be separately arranged according to needs, so that the reliability and the safety of the accelerator system are improved.
In addition, to further accommodate different racks, the winder can be arranged in the rack as an independent isolation assembly.
The above embodiments are merely illustrative of the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the content of the present invention and implement the present invention, and not to limit the scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered in the scope of the present invention.
