Description

Technical Field

[0001] This utility model belongs to the field of hydraulic pipeline reel technology, specifically relating to a reel with a series spring structure. Background Technology

[0002] Electro-hydraulic reels integrate hydraulic hoses and cables onto a single reel, enabling synchronous transmission of hydraulic power and electrical signals. This design solves the problem of requiring a separate cable reel for signal transmission in traditional equipment, thereby reducing equipment weight and improving the performance of construction machinery vehicles during high-altitude operations. However, due to the specific environmental limitations of electro-hydraulic reels, while radially increasing the outer diameter of the coil spring can effectively extend the total cable path, it also necessitates increasing the reel diameter, thus increasing the overall weight and space occupied by the reel, making it unsuitable for high-altitude operations.

[0003] A search revealed that among the existing published documents, the utility model patent with publication number CN219839317U discloses a multi-spring drive mechanism suitable for a hose reel. By increasing the number of springs in the axial direction and connecting two springs end to end into a single spring, the total number of turns that the springs can make is increased. Without changing the outer diameter of a single spring, the outer diameter of the rotating disk remains unchanged, and the number of winding turns of the rotating disk is increased.

[0004] However, the technical solution of this utility model cannot be applied to cable operation at the same time. During frequent and high-speed rotation, the cable is prone to twisting and tangling, which affects the working performance of the cable. Utility Model Content

[0005] The purpose of this utility model is to provide a series spring structure reel, comprising:

[0006] A reel assembly, wherein the reel assembly is movably mounted on a base via a spindle, and a ratchet is fitted onto the surface of the spindle;

[0007] A guide, connected to the base, is positioned on the side of the reel assembly;

[0008] A slip ring is installed at the end of the spindle away from the base.

[0009] Preferably, the reel assembly is provided with a first coil spring, a second coil spring, and a third coil spring, each of which includes an outer vortex end and an inner vortex end; the inner vortex ends of the first coil spring and the second coil spring are coaxially connected through a core sleeve on the surface of the main shaft, and the outer vortex end of the first coil spring is synchronized with the reel assembly.

[0010] Preferably, a partition is provided between the first coil spring and the second coil spring, and the partition has a hole at its center to accommodate the main shaft and the core sleeve passing through it.

[0011] Preferably, the third coil spring is disposed on the side of the second coil spring away from the first coil spring via the core sleeve on the surface of the main shaft, and the outer end of the spiral of the second coil spring and the outer end of the spiral of the third coil spring are synchronously connected.

[0012] Preferably, a spring box is provided between the second coil spring and the third coil spring.

[0013] Preferably, an end cap is mounted on the surface of the slip ring, and the end cap is fixed to the outer surface of the reel assembly.

[0014] The beneficial effects of this utility model are:

[0015] By setting a slip ring at the main shaft, signal transmission is converted into sliding contact of conductive contacts. The continuous transmission of electricity and signals is achieved through the relative movement between the rotating and fixed parts. This effectively solves the problem of needing to install a separate cable drum for signal transmission in traditional equipment, thereby reducing the weight of the equipment and improving the performance of engineering machinery vehicles when working at heights.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] like Figures 1 to 4 As shown, this embodiment provides a series spring structure reel, including: a reel assembly 1, which is movably mounted on a base 3 via a main shaft 2. (Reference) Figure 4 The main shaft 2 is fitted with a ratchet 4 structure commonly used in the art, which adopts a gear-shaped tooth design to achieve unidirectional rotation locking; the guide 5 is connected to the base 3 and is placed on the side of the reel assembly 1 to guide the path of the wound material; the slip ring 6 is installed at the end of the main shaft 2 away from the base 3. The slip ring consists of a rotating part (rotor) and a fixed part (stator). The two are connected to the brush through a conductive ring to achieve transmission. When the rotor rotates with the equipment, the brush slides on the surface of the conductive ring to maintain the electrical path, so that the signal transmission is continuous, there is no risk of entanglement, and it is suitable for 360° infinite rotation.

[0027] The reel assembly 1 is internally equipped with a first coil spring 7, a second coil spring 8, and a third coil spring 9, all made of high-strength spring steel to ensure sufficient elasticity and durability. Each of the first coil spring 7, the second coil spring 8, and the third coil spring 9 includes an outer spiral end and an inner spiral end. The inner spiral ends of the first coil spring 7 and the second coil spring 8 are coaxially connected via a core sleeve 11 on the surface of the main shaft 2. The outer spiral end of the first coil spring 7 moves synchronously with the reel assembly 1, ensuring synchronized movement.

[0028] A partition 10 is provided between the first coil spring 7 and the second coil spring 8, and the partition 10 has a hole in its center to accommodate the main shaft 2 and the core sleeve 11, preventing interference between the coil springs. The third coil spring 9 is disposed on the side of the second coil spring 8 away from the first coil spring 7 through the core sleeve 12 on the surface of the main shaft 2, and the outer end of the spiral of the second coil spring 8 and the outer end of the spiral of the third coil spring 9 are synchronously connected.

[0029] A spring box 13 is provided between the second coil spring 8 and the third coil spring 9 to limit the radial displacement of the coil springs and avoid friction between them. An end cap 14 is installed on the surface of the slip ring 6. The end cap 14 is fixed to the outer surface of the reel assembly 1 to form a closed structure for protection.

[0030] In summary, as shown in the appendix Figure 2 and 3 As shown, the first coil spring 7 and the second coil spring 8 are mounted on the surface of the core sleeve 11 with opposite spiral directions. The outer spiral end of the first coil spring 7 serves as the driving start end and is fixed to the reel assembly 1 via a positioning shaft. The third coil spring 9 is fixed on the surface of the core sleeve 12, with the spiral direction opposite to that of the second coil spring 8. The outer spiral ends of the second coil spring 8 and the third coil spring 9 are synchronously connected via a positioning shaft. At this time, the driving mechanism includes three sets of axially parallel coil springs. Since the three sets of coil springs are connected in series, when the first coil spring 7 rotates with the reel assembly 1, the outer spiral end of the first coil spring 7 drives the inner spiral end of the first coil spring 7 to rotate. Then, the inner spiral end of the second coil spring 8 is driven to rotate via the core sleeve 11. The outer spiral end of the second coil spring 8 then rotates, which in turn drives the outer spiral end of the third coil spring 9 to rotate, thereby increasing the overall number of coil springs in the series. Throughout the rotation process, the presence of the slip ring ensures that the signal transmission remains stable, guaranteeing continuous transmission, eliminating the risk of cable tangling, and enhancing the anti-interference capability of the signal transmission, making the device more suitable for the needs of engineering machinery vehicles operating at heights.
