Technical Field
[0001] This invention relates to the field of cable conveying technology, specifically to a cable conveyor and a crossing frame assembly. Background Technology
[0002] In the construction of new power transmission lines, it is often necessary to cross multiple railways, highways, and existing power lines in a single span. If the cables are laid directly on the ground, they are not only easily damaged or pulled by pedestrians and vehicles, but also pose serious safety hazards. In order to ensure that the normal operation of road traffic and the construction of the power lines can proceed simultaneously, power workers usually use materials such as bamboo and steel pipes to build crossing frames and net structures above the facilities to be crossed (the relevant technologies can be found in the crossing equipment / devices shown in patents such as CN112249964B, CN118630636A, CN102545093A, CN115967048A, CN119419645A, and CN118336588A). The cables are then raised to a certain height using lifting equipment to ensure that traffic in the crossing area is not affected.
[0003] As a core component of the crossover frame assembly, the performance of the conveyor directly affects the cable conveying efficiency. This type of cable conveyor mainly consists of two sets of reverse-drive conveyor belts, and the belt spacing is adjustable to meet the cable clamping requirements. When in use, the two sets of conveyor belts need to be moved away from each other by adjusting the components first. After the cable passes through, the conveyor belts are then controlled to move closer and clamp, and finally the cable is conveyed by reverse drive.
[0004] However, existing cable conveyors have significant limitations in practical applications: cable conveying for crossing structures involves multiple cables, and the conveyor belt spacing needs to be adjusted before and after each cable is conveyed to complete clamping and loosening operations, which is inconvenient. At the same time, the cable diameter is not completely uniform, and the joint area often exhibits "local thickening" or "local thinning" due to functional design requirements. Operators need to repeatedly adjust the conveyor belt spacing according to changes in cable diameter, especially when continuously conveying cables of different diameters, making the adjustment operation even more frequent, resulting in a cumbersome and inefficient cable conveying process. Therefore, there is an urgent need for a cable conveyor that can adapt to the conveying of cables of different diameters without the need for frequent adjustments to the conveyor belt spacing, in order to better meet the construction needs of crossing structures. Summary of the Invention

[0009] Preferably, a limiting rod is vertically provided at the end of the transmission housing; a limiting sleeve is rotatably connected to the outer wall of the limiting rod; the limiting rods on the two transmission housings are staggered in the cable conveying direction.
[0010] Preferably, the outer diameter of the limiting sleeve varies with axial direction.
[0011] Preferably, the transmission housing has a first toothed groove and a second toothed groove that are interconnected inside; the first toothed groove is cylindrical and the second toothed groove is elongated; the second toothed groove passes through the upper surface and the lower surface of the transmission housing; a gear is rotatably connected in the first toothed groove; a rack that meshes with the gear is slidably connected in the second toothed groove; a return groove is provided on the inner wall of the second toothed groove; a return block that is fixedly connected to the rack is slidably connected in the return groove; the upper surface of the return block is connected to the inner wall of the return groove by a second spring; a gear rod that is rotatably connected to the transmission housing is fixedly connected to the center of the gear; a gear sleeve is fitted on the outer wall of the gear rod; the gear sleeve is fixedly connected to a limiting rod.
[0012] Preferably, the inner wall of the toothed sleeve is provided with an annular groove; the inner wall of the annular groove is connected to the toothed bar by a torsion spring.
[0013] Preferably, the upper surface of the base is provided with a lifting groove; a lifting block is slidably connected in the lifting groove; the lifting block can slide close to or away from the vertical plate; the upper end of the lifting block is hinged to the lower surface of the transmission housing away from the vertical plate; the depth of the lifting groove becomes shallower as it moves away from the vertical plate.
[0014] A crossing frame assembly is provided, which is applicable to the aforementioned cable conveyor. The crossing frame assembly includes a forklift, a rotating platform, an insulated bridge, and a cable conveyor. The lower end of the forklift is mounted on and fixed to a truck bed.

[0017] 2. Before using the cable conveyor to transport cables, the present invention first turns the knob to drive the screw to rotate. The rotating screw will drive the two machine bases to move closer or further apart along the two slide bars, thereby changing the distance between the lower edges of the two transmission surfaces, thus meeting the needs of transporting cables of more diameters.
[0018] 3. During the flipping process of the transmission shell of this invention, the limiting rod will flip and fall directly above the cable, thereby limiting the cable in the upper position and preventing the cable from being squeezed out by the reaction force of the two transmission surfaces. This ensures the clamping effect of the cable inside the two transmission surfaces and improves the stability of the cable transmission. Attached Figure Description

[0034] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0035] like Figures 1 to 13 As shown, the present invention includes the following embodiments:
[0036] Example 1: A cable conveyor includes a frame 4 and two bases 5 on the frame 4; a first vertical groove 51 is provided on the upper surface of the two bases 5 at a position close to each other; a vertical plate 52 is slidably connected to the first vertical groove 51; the lower end of the vertical plate 52 is connected to the lower inner wall of the first vertical groove 51 by a first spring 53; the dimensions of the two vertical plates 52 increase as they move away from each other (the cross-section of the vertical plate 52 is an isosceles trapezoid); the upper ends of the two vertical plates 52 are hinged to the lower surface of the transmission housing 6 at a position close to each other; the side of the two transmission housings 6 that is close to each other is an opening; a rotating roller 61 is rotatably connected inside the transmission housing 6; one of the rotating rollers 61 is driven by a motor 62; the two rotating rollers 61 are connected to a transmission belt 63; the side of the two transmission belts 63 that is close to each other is a transmission surface 631; the two transmission surfaces 631 are distributed in an inverted V-shape.
[0037] The cable conveyor is installed on the upper surface of the rotating platform 2. After the truck transports the crossing frame assembly to one side of the area to be crossed, the forklift 1 is controlled to lift the rotating platform 2 to the required height. Then, the rotating platform 2 is rotated to move the insulated bridge 3 across the area to be crossed, such as a road. The cable is then placed directly on the two transmission surfaces 631. The distance between the upper edges of the two transmission surfaces 631 is much larger than the diameter of the cable, so the cable can easily enter the space between the two transmission surfaces 631. The distance between the lower edges of the two transmission surfaces 631 is much smaller than the diameter of the cable, so the cable cannot pass through the space between the two transmission surfaces. The cable is moved out from the lower edge of 631, thus confining the space between the two transmission surfaces 631. Since the cable conveyor is on the rotating platform 2 after the height is increased, after the cable rests on the two transmission surfaces 631, the cable will press down on the two transmission surfaces 631 under its own weight and tensile force. The cable will transfer the force to the transmission belt 63, and the transmission belt 63 will then transfer the force to the transmission housing 6. The lower surfaces of the two transmission housings 6 are higher in the vertical direction when they are close to each other than when they are far apart. The lower surfaces of the two transmission housings 6 are more abutting against the upper surface of the base 5 when they are far apart. Therefore, when the cable rests on the two transmission surfaces 631... After 31 is applied, the lower surfaces of the two transmission housings 6 will move downwards towards each other. That is, the two vertical plates 52 will be compressed and overcome by the first spring 53, moving downwards along the first vertical groove 51. As the vertical plates 52 move downwards, the transmission housings 6 will rotate with the vertical plates 52. The two transmission housings 6 will cause the two transmission belts 63 to flip upwards. The two transmission belts 63 will cause the two transmission surfaces 631 to flip upwards. The distance between the upper edges of the two transmission surfaces 631 will gradually decrease. After the upper edges of the two transmission surfaces 631 move closer together, they will clamp the inner cable. The included angle formed by the two transmission surfaces 631 will gradually decrease. The motor housing 62 and the... The upper surface of the transmission housing 6 is fixedly connected. The motor 62 drives the connected roller 61 to rotate. The roller 61 drives the corresponding transmission belt 63 to drive. The outer wall of the roller 61 and the inner wall of the transmission belt 63 are provided with teeth that can mesh and drive. The outer wall of the transmission belt 63 is provided with anti-slip grooves to achieve the purpose of anti-slip. During the transmission of the two transmission belts 63 in opposite directions, the cable is clamped and transported to the other side of the road. For cables with varying diameters, the included angle between the two transmission surfaces 631 will change positively with the change of cable diameter. Without adjustment, the cable can be clamped and driven adaptively according to the corresponding diameter.After completing the current cable transport and proceeding with the transport of other cables, the current cable is lifted upwards. During this lifting process, the first spring 53 pushes the vertical plate 52 upwards. As the vertical plate 52 moves upwards, it causes the angle between the two transmission surfaces 631 to widen and open, thus directly removing the current cable with high unloading efficiency. Then, other cables to be transported are placed inside the two transmission surfaces 631. The angle between the two transmission surfaces 631 is adjusted according to the diameter of the cable to achieve adaptive clamping for different diameters. After the cable is clamped, it is transported by the transmission belt 63. This process is repeated. Whether transporting multiple cables, cables with varying diameters, or cables of different diameters, the conveyor can achieve adaptive clamping without frequent adjustments while ensuring transmission, greatly facilitating the cross-transport of cables.
[0038] The present invention utilizes a support structure consisting of a transmission surface 631 with an adaptively adjustable included angle, a vertical plate 52, and a first spring 53, as well as an anti-slip design for the transmission belt 63. This allows it to adapt to cables of different diameters and multiple cables without frequent adjustments, while also accelerating cable loading and unloading speeds, ensuring stable transport, significantly improving operational convenience, and making cable transport across distances more efficient and reliable.
[0039] Example 2: A slide rod 41 is horizontally fixed to the frame 4; a screw 42 is rotatably connected to the frame 4; the screw 42 is threadedly connected to two machine bases 5; the slide rod 41 is slidably connected to the two machine bases 5; a knob 43 is fixedly connected to the end of the screw 42; the threads at both ends of the screw 42 are arranged in opposite directions.
[0040] In this embodiment, the two first vertical grooves 51 are connected on one side close to each other; the two first vertical grooves 51 are provided with a second vertical groove 54 on the side away from each other; the two second vertical grooves 54 are movably connected to a synchronization bar 55; the two vertical plates 52 are provided with a synchronization groove 56 on one side close to each other; the two synchronization grooves 56 are slidably connected to the synchronization bar 55; the end of the synchronization bar 55 is fixedly connected to an anti-detachment block 57.
[0041] After the cable falls onto the two transmission surfaces 631, the tension and gravity of the cable are transmitted to the two transmission surfaces 631, which will cause the two vertical plates 52 to move downward against the corresponding first springs 53. Since the synchronous grooves 56 on the two vertical plates 52 pass through the synchronous strips 55, the two vertical plates 52 will move downward synchronously under the synchronization of the synchronous strips 55, avoiding the situation where the two transmission surfaces 631 are misaligned in the vertical direction, which would cause the cable clamping to fail. The distance between the lower edges of the two transmission surfaces 631 directly affects the cable conveying range. Specifically, before using the cable conveyor to convey the cable, first turn the knob 4. 3 drives the screw 42 to rotate. The rotating screw 42 will cause the two bases 5 to move closer or further apart along the two slide bars 41, thereby changing the distance between the lower edges of the two transmission surfaces 631, thus meeting the needs of conveying cables of more diameters. This adjustment only needs to be completed before the cable is conveyed. Other cables with similar diameters can be directly clamped by the two transmission surfaces 631. The distance between the two bases 5 is only to meet the clamping needs of a wider range of diameters, and does not affect the clamping of cables with similar diameters by the two transmission surfaces 631, thus meeting the diverse cable conveying needs.
[0042] Example 3: A limiting rod 7 is vertically provided at the end of the transmission housing 6; a limiting sleeve 71 is rotatably connected to the outer wall of the limiting rod 7; the two limiting rods 7 on the transmission housing 6 are staggered in the direction of cable conveying.
[0043] In this embodiment, the outer diameter of the limiting sleeve 71 fluctuates along the axial direction.
[0044] With the two transmission surfaces 631 in a V-shape at their maximum opening, the vertical plate 52 is at its upper limit position, and the limiting rod 7 is vertically positioned. The vertical position of the limiting rod 7 on the two transmission shells 6 does not affect the insertion of the cable. After the cable rests on the two transmission surfaces 631, it transmits tension and gravity to them, causing the vertical plate 52 to move downwards. The two transmission surfaces 631 rotate as the transmission shells 6 rotate. During this rotation, the limiting rod 7 rotates, landing directly above the cable. This effectively limits the cable's position, preventing it from being squeezed out by the reaction force of the two transmission surfaces 631. This ensures the cable is clamped within the two transmission surfaces 631, improving the stability of the cable transmission. Because the outer wall of the limiting rod 7 is rotatably connected to… As the limiting sleeve 71 is used, during the process of the limiting rod 7 pressing down and contacting the cable through the limiting sleeve 71, the limiting sleeve 71 presses down on the cable on the one hand, and on the other hand, the limiting sleeve 71 moves with the cable. The corrugated outer wall of the limiting sleeve 71 moves with the cable, allowing the limiting sleeve 71 to oscillate the cable. The cable vibrates under the oscillation, which allows the cable to better enter the depth of the two transmission surfaces 631, avoiding the situation where the cable is not properly fitted in the space between the two transmission surfaces 631, and improving the subsequent clamping effect of the cable. During the cable transmission process, the corrugated outer wall of the limiting sleeve 71 can also laterally limit the cable, making the cable transmission more stable. During the cable transmission process, the limiting sleeve 71 will rotate on the outer wall of the limiting rod 7, and the limiting sleeve 71 and the cable roll in contact, resulting in less wear.
[0045] Example 4: The transmission housing 6 has a first toothed groove 64 and a second toothed groove 65 that are interconnected inside; the first toothed groove 64 is cylindrical and the second toothed groove 65 is elongated; the second toothed groove 65 passes through the upper and lower surfaces of the transmission housing 6; a gear 72 is rotatably connected in the first toothed groove 64; a rack 73 that meshes with the gear 72 is slidably connected in the second toothed groove 65; a return groove 66 is provided on the inner wall of the second toothed groove 65; a return block 74 that is fixedly connected to the rack 73 is slidably connected in the return groove 66; the upper surface of the return block 74 is connected to the inner wall of the return groove 66 by a second spring 75; a gear rod 76 that is rotatably connected to the center of the gear 72 is fixedly connected to the center of the transmission housing 6; a gear sleeve 77 is fitted on the outer wall of the gear rod 76; the gear sleeve 77 is fixedly connected to the limiting rod 7.
[0046] In this embodiment, the inner wall of the toothed sleeve 77 is provided with an annular groove 78; the inner wall of the annular groove 78 is connected to the toothed bar 76 by a torsion spring 79.
[0047] In the initial state, the lower end of rack 73 rests against the upper surface of base 5, and the lower end of rack 73 protrudes from the gap between the lower surface of transmission housing 6 and the upper surface of base 5. As the cable falls onto the two transmission surfaces 631, the vertical plate 52 moves downward, and the two transmission housings 6 flip. The transmission housings 6 drive the second tooth groove 65 closer to base 5. Rack 73, under pressure, slides along the second tooth groove 65. Rack 73 drives return block 74 to slide along return groove 66 against the second spring 75. Rack 73 drives meshing gear 72 to rotate. During the rotation of gear 72, gear 72 drives gear bar 76 to rotate. During the rotation of gear bar 76, gear sleeve 77 rotates. During the rotation of gear sleeve 77, limit bar 7 flips. During the flip of limit bar 7, limit sleeve 71 presses against the cable, achieving cable limiting and clamping. After being clamped by limit sleeve 71, the cable is held more tightly by the two transmission surfaces 631. To further improve the stability of subsequent cable transmission, the inner wall of the toothed sleeve 77 is provided with an annular groove 78. The toothed sleeve 77 and the toothed bar 76 are rotatably connected by a torsion spring 79. Therefore, the limiting sleeve 71 can press the cable tightly when facing cables of different diameters, thus improving the applicability of the limiting bar 7 and the limiting sleeve 71. During the process of lifting the cable, the two transmission shells 6 will drive the two transmission surfaces 631 to open, the vertical plate 52 will move upward, the transmission shells 6 will drive the second tooth groove 65 away from the upper surface of the base 5, the second spring 75 will push the return block 74 to reset along the return groove 66, the return block 74 will drive the rack 73 to reset along the second tooth groove 65, the rack 73 will drive the gear 72 to rotate and reset, the gear 72 will drive the toothed bar 76 and the toothed sleeve 77 to rotate and reset, and the limiting bar 7 and the limiting sleeve 71 will move away from above the cable. In this embodiment, the torsion spring 79 has a large enough torque to ensure that the limiting sleeve 71 presses the cable tightly.
[0048] Example 5: The upper surface of the base 5 is provided with a lifting groove 58; a lifting block 59 is slidably connected in the lifting groove 58; the lifting block 59 can slide close to or away from the vertical plate 52; the upper end of the lifting block 59 is hinged to the lower surface of the transmission housing 6 away from the vertical plate 52; the depth of the lifting groove 58 becomes shallower as it moves away from the vertical plate 52.
[0049] After the cable falls onto the two transmission surfaces 631, it will cause the vertical plate 52 to move downwards, and the two transmission surfaces 631 to flip inwards. During the downward movement of the vertical plate 52, it will cause the transmission shell 6 to flip. The edge of the lower surface of the transmission shell 6 away from the vertical plate 52 will cause the lifting block 59 to slide along the lifting groove 58. The depth of the lifting groove 58 will become shallower as it moves away from the vertical plate 52. Therefore, the lifting block 59 will gradually move upwards as it slides along the bottom of the lifting groove 58. During the downward movement of the vertical plate 52 and the upward movement of the lifting block 59, the two transmission surfaces 631 will quickly clamp the cable, improving the clamping efficiency and effect. During the upward movement of the two vertical plates 52, the two lifting blocks 59 will approach the vertical plate 52 along the lifting groove 58. The lifting blocks 59 will gradually decrease, causing the two transmission surfaces 631 to open quickly.
[0050] Example 6: A crossing frame assembly, which is applicable to the above-mentioned cable conveyor, the crossing frame assembly includes a forklift 1, a rotating platform 2, an insulated bridge 3, and a cable conveyor; the lower end of the forklift 1 is mounted on and fixed to the truck bed; the upper end of the forklift 1 is fixedly connected to the rotating platform 2; the cable conveyor is fixedly connected to the rotating platform 2; the rotating platform 2 extends outward and is fixedly connected to the insulated bridge 3.
[0051] Traditional crossing construction methods utilize materials such as bamboo and steel pipes to erect crossing frames and netting structures above the facilities being crossed. However, due to the inherent limitations of these traditional crossing frames, they cannot well adapt to the new situation of crossing construction. For example, bamboo crossing frames occupy a large area, have high requirements for terrain and topography, and take a long time to erect. Steel pipe crossing frames are heavy, require a large amount of transportation, and take a long time to install and dismantle. Both are only suitable for crossing low-voltage power lines. When the object being crossed is high above the ground, erecting traditional crossing frames requires multiple rows of crossing frames to be erected on both sides of the object, requiring a large investment of manpower and resources to complete the crossing construction task.
[0052] To overcome the shortcomings of existing line crossing frames, such as large area occupation, long erection time, heavy weight, and large investment of manpower and resources, this invention provides a crossing frame assembly. This crossing frame assembly has the advantages of fast operation speed, short erection period, and low safety risk. It is not only lightweight and small in size, making it easy to move, but also low in cost and reusable, greatly reducing construction costs. It is a brand-new line crossing method. Specifically, after the crossing frame assembly is assembled and fixed on the truck bed and the cables are installed, the forklift 1 drives the rotating platform 2 to rise to the target position. After the rotating platform 2 rotates 90 degrees, the cable conveyor transports the cables. The forklift 1 is bolted to the truck bed, utilizing the truck's own weight for good stability. The insulated bridge 3 in the crossing frame assembly adopts a diagonal design for greater stability, and is pulled by the overhead line.
