Description

Technical Field

[0001] The invention relates to the technical field of transport vehicles, in particular to a tower material transport vehicle. Background Art

[0002] Material transportation in transmission line construction has always been an important factor restricting the construction cycle. Especially with the continuous development of UHV power grid construction, tower materials need to be transported in batches during the construction of transmission line towers. The existing transportation methods mainly rely on human transportation, animal transportation, transport vehicle transportation, cableway transportation and air transportation. However, human transportation and animal transportation have the defects of low efficiency and high labor intensity, while cableway transportation and air transportation have too high transportation costs and are not easy to use for small and medium-sized projects. Therefore, transport vehicle transportation has become the most feasible transportation method.

[0003] However, when transporting tower materials, common van transport trucks may be unable to load or be loosely fixed due to the long length and heavy weight of each tower material. At the same time, tower material transportation involves a variety of terrains, including paved and unpaved roads, especially the "last kilometer" from the pole foundation, which is often mountainous, paddy fields or swamps, river beaches and other terrains. The unpaved roads of the "last kilometer" are often impassable and must be passed by building temporary roads, laying steel plates for reinforcement or replacing special vehicles, which increases the cost of tower material transportation and reduces transportation efficiency.

[0004] Therefore, it is necessary to design a transport vehicle that is suitable for transporting tower materials. Summary of the invention

[0005] The purpose of the present invention is to design a transport vehicle suitable for transporting tower materials to solve the problems raised in the above background technology.

[0008] Preferably, the rear axle assembly includes a rear axle connecting frame fixedly connected to the rear end of the main frame, a rear axle swing frame movably connected below the rear end of the rear axle connecting frame for swinging, a rear axle is fixed to the bottom of the rear axle swing frame, and a pair of rear axle swing cylinders for lifting the rear axle are movably connected between the upper part of the rear end of the main frame and the top of the rear axle swing frame.

[0009] Preferably, the lifting assembly includes a lifting frame, which is fixed on the top of the main frame, and lifting brackets are fixed on the bottom and right side of the cab, and the lifting bracket on the right side is movably connected to the lifting track of the lifting frame with a moving frame, and a lifting cylinder for adjusting the height of the cab is fixed between the lower part of the lifting frame and the bottom of the moving frame.

[0010] Preferably, a pair of movable legs are movably connected inside both left and right ends of the main frame, the other ends of the movable legs are fixed to the track assembly, and a telescopic hydraulic cylinder is provided between the inside of the main frame and the inside of the movable legs.

[0011] Preferably, a vehicle-mounted crane for lifting tower materials is arranged in front of the top of the main frame. The vehicle-mounted crane lifts the tower materials, which are reasonably matched according to the load of the vehicle and the shape and size of the tower materials. The tower materials are placed on the tower material frames on both sides of the vehicle.

[0012] Preferably, left and right ends of the top of the tower material support frame are movably connected with inclined tower material swing cylinders, and the telescopic ends of the tower material swing cylinders are movably connected to the bottom of the tower material frame.

[0013] Preferably, an intermediate platform is fixed on the top of the main body frame, and a crane support frame for supporting the vehicle-mounted crane is fixed on the rear end of the top of the intermediate platform.

[0017] 2. When climbing slopes and working conditions with high load requirements, the crawler assembly is used for driving. When rapid transfer is required, the tire bridge is lowered through the front axle assembly and the rear axle assembly to lift the crawler assembly off the ground, realizing rapid switching between wheels and tracks, thus adapting to various terrains such as mountains, paddy fields, swamps, and river beaches.

[0018] 3. When stacking tower materials on the tower material rack through the lifting assembly, the tower materials are stacked high, thus blocking the driver's field of vision in the cab. At this time, the mobile rack is driven to move along the lifting track through the extension and contraction of the top lowering cylinder. The movement of the mobile rack drives the lifting and lowering of the lifting bracket, and the lifting bracket drives the cab to meet the vision requirements in different driving processes.

[0027] See also Figure 1-Figure 7 In an embodiment of the present invention, the present invention provides a tower material transport vehicle, including a main body frame 1, including a main body frame 1, both left and right ends of the main body frame 1 are provided with track assemblies 2 for driving the main body frame 1, tower material support frames 3 are fixed at the centers of the left and right ends above the track assemblies 2, and mounting hole plates for fixing with the track assemblies 2 are added on both sides of the tower material support frames 3, the top of the tower material support frames 3 is movably connected with a tower material frame 4 through a rotating shaft, a bracket is used to span above the two tracks, and mounting hole plates are added on both sides to facilitate users to expand the platform, a front axle assembly 5 for lifting the front end of the main body frame 1 is provided at the front end of the main body frame 1, a rear axle assembly 6 for lifting the rear end of the main body frame 1 is provided at the rear end of the main body frame 1, a cab 7 is provided at the top front end of the main body frame 1, and a lifting assembly 8 for driving the cab 7 to rise and fall is fixed between the cab 7 and the main body frame 1.

[0028] When climbing and working under high load requirements, crawler driving is adopted, with a maximum speed of 5km / h; when rapid transfer is required, the tire bridge is lowered through the front axle assembly 5 and the rear axle assembly 6, so that the crawler assembly 2 is off the ground, and the wheel-track dual-use is quickly switched; it is planned to use rubber crawler tracks, with an effective grounding of 3200mm, a width of 450mm, an empty grounding pressure of 39kpa, and a full-load grounding pressure of 69kpa. It meets the allowable grounding pressure requirements of swamp soil in common soils. A winch is also added for emergency rescue; the tower material rack meets the loading requirements of various irregular special parts such as slender tower parts, tower feet and screw packages.

[0029] The front axle assembly 5 includes a front axle connecting frame 9 fixedly connected to the front end of the main frame 1, a front axle swing frame 10 for swinging is movably connected to the lower front end of the front axle connecting frame 9, a front axle 11 is fixed to the bottom of the front axle swing frame 10, a front axle steering cylinder 12 for controlling the direction is arranged at the bottom of the front axle 11, and a pair of front axle swing cylinders 13 for lifting the front axle 11 are movably connected between the upper front end of the main frame 1 and the top of the front axle swing frame 10.

[0030] The rear axle assembly 6 includes a rear axle connecting frame 14 fixedly connected to the rear end of the main frame 1, a rear axle swing frame 15 movably connected to the lower part of the rear end of the rear axle connecting frame 14 for swinging, a rear axle 16 is fixed to the bottom of the rear axle swing frame 15, and a pair of rear axle swing cylinders for lifting the rear axle are movably connected between the upper part of the rear end of the main frame 1 and the top of the rear axle swing frame 15.

[0031] Taking into account that tires are used for normal driving, and track assembly 2 is used for large climbing and muddy sections, track assembly 2 basically will not be driven on hardened roads such as conventional highways, so when practical tires are needed as a driving mode, the front axle steering cylinder 12 needs to be started to make it extend and retract, and the extension and retraction of the front axle steering cylinder 12 drives the front axle swing frame 10 to rotate counterclockwise with the front end rotation axis of the main frame 1 as the center, and at the same time drives the front axle to contact the ground, and the front axle steering cylinder 12 is continuously extended to make the front axle tire and the ground exert interaction force, so that the front end of the track assembly 2 is airborne, and at this time the rear axle steering cylinder 17 is started at the same time, and the above steps are repeated, so that the track assembly 2 is slightly suspended, ensuring that tires are used as a driving tool on hardened roads such as conventional highways. The driving form is planned to adopt a wheel-side drive scheme similar to that of an aerial work vehicle, and the hydraulic drive motor is a low-speed and high-torque motor specially used by Poclain.

[0032] The lifting assembly 8 includes a lifting frame 18, which is fixed on the top of the main frame 1. Lifting brackets 19 are fixed at the bottom and right side of the cab 7, and a moving frame 20 is movably connected between the right lifting bracket 19 and the lifting track of the lifting frame 18. A lifting cylinder 21 for adjusting the height of the cab 7 is fixed between the lower part of the lifting frame 18 and the bottom of the moving frame 20.

[0033] When transporting tower materials, it is necessary to stack higher tower materials on the tower material rack 4, thereby blocking the driver's field of vision in the cab 7. At this time, it is necessary to start the top-down cylinder 21, and the top-down cylinder 21 is extended and retracted to drive the mobile rack 20 to move along the lifting track. The movement of the mobile rack 20 drives the lifting and lowering of the lifting bracket 19, and the lifting bracket 19 drives the cab 7 to meet the vision requirements during different driving processes; at the same time, the safety protection plate, cylinder fixing card and pulley on the lifting rack 18 are used to protect it, save effort and reduce friction.

[0034] A pair of movable legs 22 are movably connected inside both left and right ends of the main frame 1 , and the other ends of the movable legs 22 are fixed to the track assembly 2 . A telescopic hydraulic cylinder is provided between the inside of the main frame 1 and the inside of the movable legs 22 .

[0035] When the wide band of the tower material is wider, because the inner side of the tower material frame 4 is closer to the middle platform 25, the middle platform 25 hinders the placement of the tower material. By starting the front axle assembly 5 and the rear axle assembly 6, the crawler track is slightly suspended. At this time, the telescopic hydraulic cylinder is started, and the telescopic hydraulic cylinder drives the movable legs 22 to extend outward, and the movable legs 22 drives the crawlers on both sides to extend outward. At the same time, the tower material frame 4 on the top is also extended to both sides, so that the tower material frame 4 can be away from the middle platform 25, so that wider tower materials can be placed. At the same time, when processing tower materials of normal width, the movable legs 22 are retracted to prevent the distance between the two tower material frames 4 from being large, resulting in a wider transport vehicle, thereby affecting the normal driving of the vehicle.

[0036] A vehicle-mounted crane 23 for lifting tower materials is arranged at the front of the top of the main frame 1 .

[0037] The vehicle-mounted crane 23 mainly includes a telescopic boom, an adjusting cylinder, and a slewing support. The telescopic boom is mainly used to expand the lifting radius and increase the working range. The adjusting cylinder is used to lift the lifting object. The slewing support is mainly responsible for completing the rotation of the boom. In specific work, the telescopic boom is used to lift tower materials. The tower materials are reasonably matched according to the load of the vehicle and the shape and size of the tower materials. The tower materials are placed on the tower material racks 4 on both sides of the vehicle. When the operating radius of the vehicle-mounted crane 23 is 3m, the lifting capacity can reach 3650kg, and the maximum lifting torque is 125kN.m.

[0038] The left and right ends of the top of the tower material support frame 3 are movably connected with inclined tower material swing cylinders 24, and the telescopic ends of the tower material swing cylinders 24 are movably connected to the bottom of the tower material frame 4.

[0039] When the tower materials need to be unloaded, it is only necessary to start the tower material swing cylinders 24 on both sides to make one cylinder contract and the other cylinder extend, so that the tower material frame 4 rotates around the rotating shaft connected to the tower material support frame 3, so that the tower material frame 4 tilts, and then start the transport vehicle to move, and the tower materials on the tower material frame 4 slide down, so that it can be unloaded quickly and conveniently.

[0040] An intermediate platform 25 for protecting the power system 27 is fixed on the top of the main frame 1 , and a crane support frame 26 for supporting the vehicle-mounted crane 23 is fixed on the top rear end of the intermediate platform 25 .

[0041] A power system 27 located inside the middle platform 25 is arranged on the top of the main frame 1 .

[0042] The power system 27 includes an engine, a pump, a fuel tank, a control valve, a track drive motor, a travel motor, and a drive axle. The power system 27 is used to control the entire power of the transport vehicle.

[0043] A pair of fastening hooks 28 for fixing the tower materials are arranged at equal distances in parallel arrays at the bottoms of the left and right ends of the tower material frame 4 .

[0044] The tower materials stacked in multiple layers on the tower material frame 4 are contacted and fixed by fastening the hooks 28 and the fixing ropes, thereby facilitating the fixing of the tower materials.

[0045] At the same time, the manual or remote control operating system can be selected according to the road conditions at the transfer site, the cab 7 is manually controlled + 100m wireless remote control, and the operating components in the cab 7 are all controlled by wire control.
