DETAILED DESCRIPTION

[0025] In order to make the purpose, principle and structure of the utility model clearer, it is further described below in conjunction with the drawings and specific embodiments.

[0026] like Figure 1-Figure 2 As shown, the utility model provides a detachable combined roller pay-off frame for subway construction, comprising a base frame 1, a support structure 2 and a pay-off roller 3 mounted on the support structure 2. The base frame 1 is the foundation of the entire pay-off frame, and is designed with a through slot 11 for connecting the support structure 2. The support structure 2 can be movably connected to the through slot 11 of the base frame 1. The support structure 2 is used to set up the pay-off roller 3 in the supporting state; in the tilted state, it is convenient for the movement or storage of the pay-off frame. The base frame is provided with two through slots 11, and each through slot 11 is configured with a group of such support structures 2 to enhance stability and bearing capacity.

[0027] The pay-off roller 3 in this embodiment is the core component of the pay-off frame, which is composed of multiple roller units 31. The multiple roller units are distributed at different positions of the pay-off roller through partitions 4 to form different installation intervals to accommodate different numbers of cables for simultaneous pay-off.

[0028] Specifically, if Figure 1-Figure 2 As shown, the base frame 1 is provided with two parallel through slots 11, which can provide a stable connection point for the support structure 2. The through slots 11 are provided with three groups of positioning holes 12 on the sides thereof, so as to fix the position of the support structure 2.

[0029] The support structure 2 includes a first oblique rod 21, a second oblique rod 22 and a vertical rod 23, both ends of which are respectively provided with through holes.

[0030] like Figure 1-Figure 2As shown, when the support structure 2 is used to set up the pay-off roller 3, the vertical pole 23 is perpendicular to the base frame 1, and the first diagonal rod 21 and the second diagonal rod 22 on both sides are symmetrically arranged on both sides of the vertical pole 23, and the lower ends of the three are all located in the through groove 11 and connected to the positioning holes 12 on the side of the through groove 11, and are fixed with bolts; the upper ends are fixed at the same point and are also positioned with bolts to form a stable triangular structure.

[0031] like Figure 3 As shown, when the pay-off rack needs to be moved or stored, the first diagonal rod 21, the second diagonal rod 22 and the vertical rod 23 will be tilted accordingly for easy operation. Specifically, first release the lower ends of the second diagonal rod 22 and the vertical rod 23 from the through slot 11, and then rotate the second diagonal rod 22 and the vertical rod 23 along the upper fixed point until the first diagonal rod 21, the second diagonal rod 22 and the vertical rod 23 are in a straight line, and then tilt the three and contact with the base frame 1, at this time, the bracket structure 2 is laid down, which is convenient for the movement or storage of the pay-off rack. Correspondingly, the pay-off roller 3 can be placed in the hollow cavity of the base frame 1 to prevent the device from rolling out of the base frame. The various components of the pay-off roller 3 can also be removed, placed in a storage box, and then placed in the hollow cavity of the base frame 1.

[0032] More specifically, a roller groove 24 is fixed at the top of the vertical rod 23 for supporting the pay-off roller 3. A rotating drum is arranged in the roller groove to facilitate the rotation of the pay-off roller. In order to prevent the pay-off roller 3 from being separated from the roller groove 24 during use, a cover groove 25 is also arranged. The roller groove 24 and the cover groove 25 are respectively provided with arc-shaped inner side surfaces, and the two ends of the cover groove 25 are fixed to the upper end surface of the roller groove 24 by bolts.

[0033] In this embodiment, Figure 4-Figure 9 As shown, each roller unit 31 is designed as a whole by a mother tube 311 and a sub-tube 312. The outer wall of the sub-tube 312 is provided with an insert 313, and the mother tube 311 is provided with a slot 314 adapted thereto. The length of the sub-tube 312 is greater than that of the mother tube 311, so that a partition 4 can be placed between adjacent roller units 31.

[0034] The pay-off roller 3 also includes a positioning shaft 32 that runs through all roller units, and a first end 33 and a second end 34 are fixedly connected at both ends. The first end 33 is provided with a fixing section 331 suitable for inserting into the mother cylinder 311, and the second end 34 is provided with a connecting section 341 to accommodate the insertion of the sub-cylinder 312. A cavity for clamping the positioning shaft 32 is also arranged in the mother cylinder 311 and the sub-cylinder 312, wherein the outer wall of the positioning shaft 32 is provided with a positioning convex strip, and the cavity is provided with a groove adapted thereto. Due to the connection structure design of the positioning convex strip and the groove between the positioning shaft 32 and the roller unit 31, and the connection structure design of the slot 314 and the insertion strip 313 of the adjacent roller unit 31, the overall structure of the pay-off roller 3 is stable.

[0035] To ensure that the partition can be stably placed between the roller units 31 , the thickness of the partition 4 is equal to the gap width formed after the adjacent roller units are plugged in. To effectively isolate multiple groups of cables, the diameter of the partition 4 is designed to be larger than the outer diameter of the mother cylinder 311 .

[0036] In this embodiment, a travel wheel with a brake function is also installed on the lower end surface of the base frame 1, so that the entire pay-off frame is more convenient and safer when moving.

[0037] In actual operation, a filling plate 5 is also provided, such as Figure 10-11 As shown, its diameter is equal to the outer diameter of the mother cylinder 311. When the distance between the partitions required by the pay-off frame needs to be designed to be larger to be suitable for thicker cables, a filling plate 5 is placed between adjacent roller units to fill the gap between adjacent roller units 31, so that the span between the two partitions 5 is the length corresponding to 2 or more roller units. The partition 4 and the filling plate 5 are respectively provided with a perforation adapted to the sub-cylinder 312 at the center for easy installation.

[0038] The detachable pay-off frame for metro electromechanical construction provided in this embodiment has a pay-off roller 3 composed of multiple groups of roller units 31, partitions 4 are arranged between the roller units 31, and multiple cable placement spaces can be formed between the partitions 4, so that multiple groups of cables can be paid out at the same time.

[0039] The detachable pay-off frame for metro electromechanical construction provided in this embodiment has a through slot 11 arranged on the base frame 1, and the first oblique rod 21, the second oblique rod 22 and the vertical rod 23 constituting the support structure 2 can form a stable tripod body to realize the installation of the pay-off roller, and can also be partially dismantled so that the first oblique rod 21, the second oblique rod 22 and the vertical rod 23 are in line and close to the base frame, which is convenient for movement or storage.

[0040] The above is only a specific implementation method of this utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the utility model, according to the technical solution and new concept of the utility model, shall be covered by the protection scope of the utility model.
