Description

Technical Field

[0001] This invention relates to the field of optical cable transport vehicle technology, and in particular to a communication optical cable transport vehicle suitable for mountainous areas. Background Technology

[0002] Currently, the transportation of optical cables in mountainous areas mostly relies on manual carrying, and there is no good labor-saving transportation equipment. Existing conventional optical cable transport vehicles have large chassis and four wheels, occupying a large area. When facing uneven mountainous terrain, their positioning is unstable, making them difficult to apply.

[0003] For example, in Chinese patent literature, patent number CN 2013206620403, authorized and announced on June 25, 2014, entitled "A Fiber Optic Cable Roller Handcart", discloses a fiber optic cable roller handcart, which includes a push handle, a frame-type carriage body and casters connected to the bottom of the carriage body. The frame-type carriage body has a fiber optic cable roller slot in the middle, which is formed by two angle steels with an isosceles triangular cross section installed longitudinally opposite each other, and it is a cavity-type slot.

[0004] The existing technology has the following shortcomings:

[0005] 1. The loading of communication optical cable carts is inconvenient, lacking an integrated portable mechanism to assist in loading;

[0006] 2. The vehicle chassis occupies a large space and uses four-wheel alignment at each of the four corners of the chassis, making it difficult to adapt to the uneven terrain in mountainous areas;

[0007] 3. Without steering wheels, steering is inconvenient, and it is prone to tipping over when pulled on mountainous terrain, resulting in poor stability. Summary of the Invention

[0008] In view of the above-mentioned shortcomings of the prior art, the present invention provides a communication optical cable transport vehicle suitable for mountainous areas, which has an integrated tailgate to facilitate loading and unloading, improve the loading and unloading efficiency of optical cables on the communication optical cable vehicle, facilitate the application of optical cable transport vehicles in mountainous areas, and improve the efficiency of optical cable transportation.

[0009] Another objective of this invention is to facilitate transportation in mountainous areas and positioning on uneven terrain, thereby improving the reliability of optical cable transportation in mountainous regions.

[0010] To achieve the above-mentioned objectives, the present invention proposes the following technical solutions.

[0011] A communication optical cable transport vehicle suitable for mountainous areas is characterized by comprising a vehicle body, a handrail at the front end of the vehicle body, several transport wheels on the lower side of the vehicle body, an optical cable placement rack on the upper side of the vehicle body, an adjustable tail plate at the rear of the vehicle body, the adjustable tail plate being able to rotate to the outer end to abut the ground, and a binding node on the optical cable placement rack.

[0012] This application features an adjustable enclosure that can rotate to the outer end to touch the ground, forming a ramp that facilitates loading and unloading, thus improving loading and unloading efficiency. It can also be recycled onto the vehicle body for easy transport. The binding node design allows the loaded optical cable to be securely tied to the optical cable rack, improving safety and increasing the efficiency of optical cable transportation in mountainous areas.

[0013] Preferably, the optical cable rack includes a mounting plate connected to the upper side of the vehicle body. The mounting plate has an arc-shaped guard plate located at the end of the mounting plate facing the front of the vehicle body, with the guard plate protruding outwards in the middle. The guard plate corresponds to the coiled optical cable, achieving an arc-shaped positioning and fit, thus improving safety.

[0014] Preferably, the adjustable tailgate is hinged at the rear of the vehicle body. Besides this method, a traditional sliding plate with an external hinge can also be used. For example, the mounting plate has an internal receiving groove with sliding guide grooves on both sides. The front of the adjustable tailgate has guide posts on both sides, and guide pulleys at the outer ends of the guide posts. The guide pulleys slide within the receiving groove, and the outer ends of the sliding guide grooves have limiting parts for the guide pulleys. When the adjustable tailgate is pulled to the end of the sliding guide groove, it can rotate downwards and can be stored in the receiving groove when not in use. Compared to this method, the preferred adjustable tailgate is rotatably located at the rear of the vehicle body, facilitating adjustment. Furthermore, when the optical cable is placed and tightened, the adjustable tailgate can be tightened and fitted against the side of the optical cable, further improving the reliability of the optical cable's positioning and resulting in better performance.

[0015] Preferably, the handrail adopts a telescopic structure, comprising an upper section and a lower section that are slidably connected. The upper end of the upper section is equipped with an operating crossbar, and the lower end of the upper section is slidably connected to the upper end of the lower section. The lower section is rotatably connected to the vehicle body, with its lower end extending out of the vehicle body. The lower end of the lower section is equipped with a guide wheel. The height of the handrail is adjustable for ease of use; the lower section of the handrail is connected to the guide wheel, which rotates when the handrail rotates, facilitating vehicle guidance.

[0016] Preferably, a deflector bar is fixedly installed on the lower section, with synchronizing rods rotatably connected to both ends of the deflector bar. The fiber optic cable placement frame is rotatably mounted on the vehicle body. A rotating shaft for connecting to the vehicle body is provided on the lower end face of the fiber optic cable placement frame, with the outer end of the rotating shaft extending to the underside of the vehicle body. An operating rod of the same length as the deflector bar is provided on the rotating shaft, with synchronizing rods rotatably connected to both ends of the operating rod. The deflector bar, synchronizing rod, and operating rod form a parallelogram structure, so that the fiber optic cable placement frame rotates synchronously when the guide wheels rotate, thereby synchronously adjusting the center of gravity of the fiber optic cable placement frame, shifting the center of gravity of the fiber optic cable placement frame towards the turning direction, and improving the vehicle body's anti-tipping ability.

[0017] Furthermore, the synchronizing rod is made of highly elastic material, while the deflector and operating rod are made of steel. The synchronizing rod adopts a composite rod structure with a plastic rod covered with rubber on the outside, which has stable tensile characteristics and complete deformation under compression. When the lower section rotates together with the deflector, the synchronizing rod on the compression side undergoes greater deformation, thereby making the rotation angle of the rotating shaft smaller than that of the lower section. The deflection of the guide wheel, the deflection of the second wheel group, and the first wheel group form a smooth arc-shaped turning guide, further improving the stability of the optical cable transport vehicle.

[0018] Preferably, the outer circumference of the transport wheels is provided with serrated patterns. This increases the coefficient of friction on the wheel surface, improves safety during transportation, and prevents slippage.

[0019] Preferably, the vehicle has four transport wheels, including a first wheel group located at the rear of the vehicle body and a second wheel group located at the lower end of the rotating axle. The two transport wheels of the first wheel group are located on both sides of the rear of the vehicle body, and the two transport wheels of the second wheel group are coaxially and closely arranged together. The coaxial and close arrangement of the second wheel group occupies less space, and the vehicle width can be set to be narrower. Vehicle positioning is achieved through the transport wheels and guide wheels. When the optical cable transport vehicle is transporting on uneven terrain in mountainous areas, even if the ground is uneven or the vehicle turns, at least the guide wheel, one transport wheel of the first wheel group, and one transport wheel of the second wheel group form a triangular planar positioning. Because the second wheel group is positioned corresponding to the rotating axle, it is closer to the center of gravity of the vehicle, which allows the gap between the two transport wheels of the first wheel group to be smaller than that of wheel positioning, reducing the lateral size occupied by the vehicle body and making the optical cable transport vehicle more suitable for mountainous applications.

[0020] Preferably, the lower section includes a first lower section and a second lower section. The lower end of the first lower section and the upper end of the second lower section are hinged together. The upper end of the first lower section is slidably connected to the upper section. The second lower section is rotatably connected to the vehicle body, and the lower end of the second lower section extends out of the vehicle body. This allows the first lower section to rotate around the hinge point, facilitating vehicle body steering adjustment and pulling.

[0021] The beneficial effects of this invention are: it forms a ramp that facilitates loading and unloading, improving loading and unloading efficiency; it can be recycled back to the vehicle body for easy transport during normal use; the binding node setting can tightly bind the loaded optical cable to the optical cable placement rack, improving safety and increasing the efficiency of optical cable transportation in mountainous areas; when the guide wheels rotate, they can synchronously adjust the center of gravity of the optical cable placement rack, improving the vehicle's anti-tipping ability; the wheels can form a triangular positioning surface with minimal lateral footprint, making the optical cable transport vehicle more suitable for mountainous applications.

[0028] Example 1,

[0029] like Figure 1As shown, a communication optical cable transport vehicle suitable for mountainous areas includes a vehicle body 1. A handrail is provided at the front end of the vehicle body 1. The handrail has a telescopic structure and includes a slidingly connected upper section 2 and a lower section. The lower section is rotatably connected to the vehicle body 1, and its lower end extends out of the vehicle body 1. Specifically, the lower section includes a first lower section 3 and a second lower section 4. The lower end of the first lower section 3 and the upper end of the second lower section 4 are hinged. The upper end of the first lower section 3 is slidably connected to the upper section 2, and the second lower section 4 is rotatably connected to the vehicle body 1. The lower end of the second lower section 4 extends downwards from the vehicle body 1. The cross-section of both the upper section 2 and the second lower section 4 is cylindrical. A bearing assembly is provided on the vehicle body 1 to rotatably connect with the second lower section 4. A guide wheel 5 is provided at the lower end of the second lower section 4 via a wheel frame. An operating crossbar 6 is provided at the upper end of the upper section 2. The middle position of the operating crossbar 6 is fixedly connected to the upper end of the upper section 2, and the operating crossbar 6 is perpendicular to the plane where the guide wheel 5 is located. The lower end of the upper section 2 and the upper end of the lower section are slidably connected. The inner diameter of the lower section and the outer diameter of the upper section 2 are clearance-fitted. The upper section 2 and the lower section are provided with recessed radial synchronous grooves 7 along their axes to prevent relative rotation. The lower section wall is provided with locking bolts 20 that fit with the upper section 2. The position of the upper section 2 within the lower section is adjusted by tightening the locking bolts 20. The height of the handrail is adjustable for ease of use. The lower section of the handrail is connected to the guide wheel 5, which can drive the guide wheel 5 to rotate when the handrail rotates, facilitating the guidance of the vehicle body 1. Several transport wheels 8 are provided on the lower side of the vehicle body 1, corresponding to the lower side of the middle and rear of the vehicle body 1. An optical cable placement rack is provided on the upper side of the vehicle body 1, and the optical cable placement rack is embedded and fixedly installed on the vehicle body 1. An adjustable tail plate 9 is provided at the rear of the vehicle body 1, and the adjustable tail plate 9 is hinged at the rear of the vehicle body 1. The adjustable tailplate 9 can rotate to its outer end touching the ground. On a horizontal plane, when the outer end of the adjustable tailplate 9 touches the ground, the rotation angle of the adjustable tailplate 9 is 24 degrees. A binding node 10 is provided on the optical cable placement rack. The optical cable placement rack includes a mounting plate 11 connected to the upper side of the vehicle body 1. An arc-shaped guard plate 12 is provided on the mounting plate 11, located at the end of the mounting plate 11 facing the front of the vehicle body 1, with the guard plate 12 protruding outwards in the middle. More precisely, the guard plate 12 is semi-cylindrical in shape, with the inner diameter of the guard plate 12 corresponding to the diameter of the tube frame 19. The binding nodes 10 are located at both ends and the middle of the inner side of the guard plate 12. The binding node 10 has a circular ring structure, facilitating rope routing. The guard plate 12 corresponds to the tube frame 19 on which the communication optical cable is wound, achieving an arc-shaped positioning and fit, improving safety. This application features an adjustable enclosure that can rotate to its outer end to contact the ground, forming a ramp that facilitates loading and unloading, thus improving loading and unloading efficiency. It can also be retracted onto the vehicle body 1 for easy transport. The binding node 10 can securely bind the loaded optical cable to the optical cable rack, improving safety and increasing the efficiency of optical cable transportation in mountainous areas. When the optical cable is placed in position and secured, the adjustable tail plate 9 can also be secured and attached to the side of the optical cable, further improving the reliability of the optical cable limit and achieving better results. Figure 1 The dashed line in the middle indicates the position where the adjustable tailplate 9 can rotate.

[0030] Example 2,

[0031] like Figures 2 to 4As shown, a communication optical cable transport vehicle suitable for mountainous areas includes a vehicle body 1, which is a rectangular flat structure. A handrail is provided at the front end of the vehicle body 1. The handrail has a telescopic structure and includes a slidingly connected upper section 2 and a lower section. The lower section is rotatably connected to the vehicle body 1, and its lower end extends out of the vehicle body 1. Specifically, the lower section includes a first lower section 3 and a second lower section 4. The lower end of the first lower section 3 and the upper end of the second lower section 4 are hinged. The upper end of the first lower section 3 is slidably connected to the upper section 2, and the second lower section 4 is rotatably connected to the vehicle body 1, with its lower end extending out of the vehicle body 1. A guide wheel 5 is provided at the lower end of the second lower section 4 via a wheel frame. An operating crossbar 6 is provided at the upper end of the upper section 2. The middle position of the operating crossbar 6 is fixedly connected to the upper end of the upper section, and the operating crossbar 6 is perpendicular to the plane where the guide wheel 5 is located. The lower end of the upper section 2 and the upper end of the lower section are slidably connected. The inner diameter of the lower section and the outer diameter of the upper section 2 are clearance-fitted. The upper section 2 and the lower section are provided with recessed radial synchronous grooves 7 along their axes to prevent relative rotation between them. The height of the handrail is adjustable for ease of use. The lower section of the handrail is connected to the guide wheel 5, which can drive the guide wheel 5 to rotate when the handrail rotates, facilitating the guidance of the vehicle body 1. Several transport wheels 8 are provided on the lower side of the vehicle body 1, corresponding to the lower side of the middle and rear of the vehicle body 1. A fiber optic cable placement rack is provided on the upper side of the vehicle body 1. The fiber optic cable placement rack is rotatably mounted on the vehicle body 1. The lower end face of the fiber optic cable placement rack is provided with a rotating shaft 13 for connecting with the vehicle body 1. The vehicle body 1 is provided with a bearing assembly that matches the rotating shaft 13. The bearing assembly can withstand axial and radial loads. A deflector rod 14 is fixedly provided on the second lower section 4. The middle part of the deflector rod is provided with a sleeve for screw fixing after being sleeved with the second lower section 4. Synchronizing rods 15 are rotatably connected to both ends of the steering lever 14. The outer end of the rotating shaft 13 extends to the lower side of the vehicle body 1. An operating lever 16 of the same length as the steering lever 14 is provided on the rotating shaft 13. A sleeve for screw fixing after being sleeved with the rotating shaft 13 is provided in the middle of the rotating shaft 13. The two ends of the operating lever 16 are rotatably connected to the synchronizing rods 15. There are four transport wheels 8, and the outer circumference of the transport wheels 8 is provided with serrated patterns. The transport wheels 8 include a first wheel set 17 located at the rear of the vehicle body 1 and a second wheel set 18 located at the lower end of the rotating shaft 13. The two transport wheels 8 of the first wheel set 17 are located on both sides of the rear of the vehicle body 1, and the two transport wheels 8 of the second wheel set 18 are coaxially and closely arranged together. The synchronizing rod 15 is made of a highly elastic material, while the deflecting rod 14 and the operating rod 16 are made of steel. The synchronizing rod 15 is a composite rod structure with a plastic rod covered with rubber on the outside. It has stable tensile characteristics and is completely deformed under pressure. When the lower section rotates together with the deflecting rod 14, the synchronizing rod 15 on the pressure side undergoes greater deformation, which makes the rotation angle of the rotating shaft 13 smaller than that of the lower section. The deflection of the guide wheel 5, the deflection of the second wheel group 18, and the first wheel group 17 form an arc-shaped smooth turning guide, further improving the stability of the optical cable transport vehicle.

[0032] An adjustable tailplate 9 is provided at the rear of the vehicle body 1, and the adjustable tailplate 9 is hinged at the rear of the vehicle body 1. The adjustable tailplate 9 can rotate to the point where its outer end touches the ground. On a horizontal plane, when the outer end of the adjustable tailplate 9 touches the ground, the rotation angle of the adjustable tailplate 9 is 24 degrees. A binding node 10 is provided on the optical cable rack. The optical cable rack includes a mounting plate 11 connected to the upper side of the vehicle body 1. The mounting plate 11 has an arc-shaped guard plate 12, which is located at the end of the mounting plate 11 facing the front of the vehicle body 1. The guard plate 12 protrudes outward at the middle position. The guard plate 12 is semi-cylindrical in shape, and the diameter of the inner side of the guard plate 12 corresponds to the diameter of the tube frame 19. The binding nodes 10 are located at both ends and the middle position of the inner side of the guard plate 12.

[0033] The deformation rod, synchronization rod 15, and operating rod 16 form a quadrilateral structure, so that when the guide wheel 5 rotates, the optical cable placement frame rotates synchronously, thereby synchronously adjusting the center of gravity of the optical cable placement frame, shifting the center of gravity of the optical cable placement frame towards the turning direction, and improving the anti-tipping ability of the vehicle body 1. The second wheel set 18 is set coaxially and close together, occupying little space, and the width of the vehicle body 1 can be set to be narrower. The positioning of the vehicle body 1 is achieved by the transport wheel 8 and the guide wheel 5. When the optical cable transport vehicle is transported on uneven mountainous ground, even if the ground is uneven or the vehicle body 1 turns, at least the guide wheel 5, one transport wheel 8 of the first wheel set 17, and one transport wheel 8 of the second wheel set 18 form a triangular plane positioning, which is not easy to tip over. Moreover, because the second wheel set 18 is set to correspond to the rotation shaft 13, the second wheel set 18 is close to the center of gravity of the vehicle body 1, so the gap between the two transport wheels 8 of the first wheel set 17 can be controlled to be smaller than that of wheel positioning, reducing the lateral size occupied by the vehicle body 1, making the optical cable transport vehicle more suitable for mountainous applications.
