Description

Technical Field

[0001] This utility model relates to the field of aviation maintenance equipment technology, and in particular to a cable winding and unwinding vehicle. Background Technology

[0002] In the aviation industry, aircraft maintenance and support are of paramount importance. To ensure the safe operation of aircraft, various support equipment is required on the ground during pre-flight, post-flight, scheduled maintenance, and troubleshooting operations. This equipment includes work ladders, lighting equipment, hydraulic systems, and various power supply devices. This support equipment must be quickly in place and reliably secured after the aircraft arrives at the airport to support efficient maintenance work; and after maintenance is completed, this equipment must be quickly removed to ensure the normal operation of the airport.

[0003] Currently, most cable winding and unwinding vehicles use hydraulic pallet trucks or fixed reels to achieve cable winding and unwinding. Hydraulic pallet trucks are relatively cumbersome to use when moving and fixing equipment, and hydraulic trucks are prone to failure. Fixed reels cause the cable to rub against the ground during winding and unwinding, which can easily damage the cable and is laborious to operate.

[0004] Based on this, in order to improve the convenience of cable winding and unwinding, we propose a cable winding and unwinding vehicle. Utility Model Content

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0036] Reference Figure 1-9 As one embodiment of this utility model, a cable winding and unwinding vehicle is disclosed. Specifically, the cable winding and unwinding vehicle includes: a frame 1 and a drum 2 rotatably connected in the frame 1, with a wire 3 wound around the outside of the drum 2;

[0037] The frame 1 has a drive assembly 4 installed on its side to drive the drum 2 to rotate, a cable assembly 5 installed on the frame 1 in the cable outlet direction, a roller assembly 6 and a brake assembly 7 for stopping the roller assembly 6 at the bottom of the frame 1.

[0038] In some embodiments, the frame 1 of this utility model includes a base frame 11 and two side frames 12 fixed on the base frame 11. The side frames 12 have a U-shaped structure, and a pressure shaft 13 surrounding the outside of the drum 2 is rotatably connected between the two side frames 12. The design of the pressure shaft 13 can prevent the wire 3 from becoming loose or tangled. Of course, multiple pressure shafts 13 can be provided in this embodiment to ensure the stability of the outer protection of the entire drum 2.

[0039] The two ends of the drum 2 are rotatably connected to the two side frames 12 respectively.

[0040] Furthermore, in this embodiment, the inside of the drum 2 is a hollow structure, and one end of the wire 3 passes through the drum 2 and extends into the interior of the hollow structure;

[0041] A cable connector 8 is rotatably connected to one end of the shaft of the drum 2. The connecting wire of the cable connector 8 passes through the hollow structure along the shaft end and is electrically connected to one end of the conductor 3 through an electric slip ring.

[0042] Specifically, in this embodiment, the shaft end of the drum 2 is provided with a through hole that connects to the interior of its hollow structure. The electric slip ring can be installed in this through hole. By adopting the design of the cable connector 8, convenient wiring of the entire conductor 3 can be achieved. At the same time, the electric slip ring can meet the stable power supply requirements of the drum 2 when it is rotating.

[0043] Based on the above embodiments, the cable assembly 5 in this embodiment includes a cable shaft 51 and a slide bar 52 fixedly installed between two side frames 12. The outer side of the cable shaft 51 is formed with a spiral guide groove 53.

[0044] A slide block 54 is sleeved on the outer side of the cable spool 51. A guide shaft 55 is threadedly connected to the end face of the slide block 54. The guide shaft 55 is slidably connected in the spiral guide groove 53. The slide block 54 and the slide rod 52 are slidably connected. A spiral baffle 21 is also installed on the outer side of the drum 2. The spiral baffle 21 provided in this utility model can be used to wind the wire 3 to ensure that the wire 3 is stably wound around the entire outer side of the drum 2.

[0045] When the drum 2 winds up the wire 3, the wire guide shaft 51 also rotates. When the wire guide shaft 51 rotates, the entire slide 54 can be controlled to move linearly by means of the cooperation of the guide shaft 55 and the spiral guide groove 53. Since one side of the slide 54 and the slide rod 52 are connected by a sliding connection, the slide 54 will not rotate, thus ensuring the stability of the linear movement.

[0046] Of course, in order to guide the wire 3, four corner plates 56 are distributed in a matrix above the slide 54 in this embodiment. Guide wheels 57 are connected between the opposite faces of the four corner plates 56. The wire 3 passes through the multiple guide wheels 57. It should be noted that in this embodiment, the two lower corner plates 56 are fixedly connected to the upper part of the slide 54.

[0047] Specifically, when the drum 2 is winding and the slide 54 is moving laterally, the guide wheel 57 constrains the wire 3, which can drive the wire 3 to move while winding, so as to spirally wind and wind it around the outside of the entire drum 2. Preferably, the guide wheel 57 in this embodiment is set as a V-shaped wheel to ensure the guiding stability of the wire 3.

[0048] Preferably, in this embodiment, the drive assembly 4 includes a first sprocket 41 and a second sprocket 42 fixed on the shaft end of the drum 2, and a third sprocket 43 is fixedly installed on the outer side of the cable shaft 51. The third sprocket 43 and the second sprocket 42 are driven by a chain.

[0049] A handwheel 44 and a transmission gear 45 are rotatably connected to the outer side of the side frame 12. A drive gear 46 that meshes with the transmission gear 45 is fixedly installed on the outer side of the handwheel 44. A fourth sprocket 47 is fixedly installed on the side of the transmission gear 45. The fourth sprocket 47 is driven by a chain and the first sprocket 41.

[0050] That is, when the conductor 3 is actually wound up, the handwheel 44 mentioned above can be turned to drive the transmission gear 45 to rotate by means of the drive gear 46. Then the transmission gear 45 drives the drum 2 to rotate through the fourth sprocket 47 and the first sprocket 41, so as to realize the winding operation of the conductor 3.

[0051] At the same time, when the drum 2 rotates, the second sprocket 42 and the third sprocket 43 will also be driven by the chain, so as to synchronously drive the cable shaft 51 to ensure that when the wire 3 is wound, the wire 3 is spirally wound on the outside of the cable shaft 51.

[0052] Similarly, when laying out the wire, simply pull one end of the conductor 3 outward to achieve the operation of unwinding while moving.

[0053] The above embodiment uses a sprocket and chain transmission structure as an example. In other embodiments, the chain and sprocket structure can be replaced with a synchronous belt and synchronous pulley transmission structure to achieve the same technical effect.

[0054] Preferably, in this embodiment, the outer side of the frame 1 is detachably connected to a cover plate 9 that covers the drive assembly 4. The cover plate 9 covers the outer side of the plurality of sprockets and chains. Of course, the gripping part of the handwheel 44 should protrude from the outer side of the cover plate 9. In this embodiment, the cover plate 9 can be fixed to the side of the frame 1 with bolts. In addition, in order to facilitate the convenient movement of the entire device, a handle 10 is also fixedly installed on the side of the frame 1 in this embodiment.

[0055] In some embodiments, the roller assembly 6 of the present invention includes two directional wheels 61 rotatably connected to the underside of the frame 1 and at least one universal wheel 62, and the brake assembly 7 is used to brake the two directional wheels 61 to a stop.

[0056] Based on the above embodiments, the brake assembly 7 in this embodiment includes a brake plate 71 and a drive shaft 72 rotatably connected to the underside of the frame 1. Two connecting pieces 73 are fixedly installed on the outer side of the drive shaft 72. A pull rod 75 is snapped onto the end face of the connecting piece 73 through a waist hole 74. It should be noted that the end of the pull rod 75 in this embodiment has an inwardly recessed portion, which slides in the waist hole 74. At the same time, the end of the inwardly recessed portion is limited by a threaded nut. The design of the inwardly recessed portion sliding in the waist hole 74 can satisfy the rotational movement path of the drive shaft 72 and meet the control stability of the pull rod 75. The other end of the pull rod 75 is pin-connected to the brake plate 71, and a tension spring 76 is fixedly connected between the other end of the pull rod 75 and the frame 1.

[0057] Furthermore, in this embodiment, a foot pedal 77 is rotatably connected to the outer side of the drive shaft 72, and a limiting plate 78 is fixedly installed at the bottom of the frame 1. An L-shaped groove 79 is provided on the end face of the limiting plate 78, and the shaft end of the foot pedal 77 is slidably connected in the L-shaped groove 79.

[0058] In the specific braking operation, the foot pedal 77 mentioned above can be pressed first. The foot pedal 77 will drive the drive shaft 72 to rotate. The drive shaft 72 pulls the lever 75 laterally through the connecting piece 73 on its outer side. Then the lever 75 drives the brake plate 71 to rotate until the brake plate 71 abuts against the outer surface of the directional wheel 61 to achieve the braking effect on the entire device.

[0059] Of course, in order to maintain the braking state, the foot pedal 77 can be rotated further so that the axle of the foot pedal 77 slides into the lateral part of the L-shaped groove 79 for locking and limiting, thus maintaining the braking state.

[0060] Reference Figure 8 , Figure 9 In this embodiment, telescopic rods 14 are fixedly installed on both sides of the frame 1. The two sections of the telescopic rod 14 are locked together by bolts. Several U-shaped frames 15 are rotatably connected between the tops of the two telescopic rods 14. Specifically, a connecting plate is fixedly installed on the top of the telescopic rod 14. The U-shaped frames 15 are rotatably connected to the connecting plate by bolts. Of course, the bolts and the connecting plate are threaded together. Thus, the rotation angle of the U-shaped frames 15 can be locked and positioned by locking the bolts.

[0061] A tarpaulin 16 is fixedly connected between the outer sides of several of the U-shaped frames 15. The design of the tarpaulin 16 enables rain and sun protection for the top of the entire device, thereby improving its reliability for outdoor use.

[0062] In this embodiment, a power distribution cabinet 17 is fixedly installed on both sides of the vehicle frame 1. An electrical component 18 is fixedly installed inside the power distribution cabinet 17. Preferably, the electrical component 18 in this embodiment can be a transformer, an air switch, or an aviation plug, etc., for the purpose of supplying power to the outside. Of course, the electrical component 18 is electrically connected through wires and cable connectors 8, so as to realize the power supply to the electrical component 18.

[0063] In summary, the combination of the drum 2 and the cable assembly 5 in this utility model allows the wire 3 to be evenly arranged on the outside of the drum 2 for winding, which greatly improves the stability and convenience of winding and unwinding operations. Secondly, the integrated roller assembly 6 can meet the purpose of convenient overall movement, and the brake assembly 7 can be used to conveniently stop the roller assembly 6, further improving the stability during winding and operation.

[0064] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
