Description
Technical Field
The invention relates to the technical field of transfer equipment, in particular to a heavy-load semi-trailer flat car.
Background
At present, large-scale equipment such as a machine room of a shore container crane and the like is required to be transported among different factories in intermediate links such as structural member manufacturing, mechanism assembly, paint spraying, in-factory inspection, test run and the like, and the transportation work of the equipment such as a temporary renting heavy truck, a heavy truck crane and the like is completed by the combined operation of the equipment in a traditional mode. Because the equipment is heavy, the overall dimension is big, and on-site transportation is time consuming and laborious, influences work efficiency, occupies a large amount of equipment resources again, and economic nature is very poor.
The traditional semi-trailer has the following defects that the transportation of large equipment is required to be completed:
the shipping capacity is small. The loading weight of a common semi-trailer flat car is below 15 tons, and the wheel pressure is increased by increasing the loading weight, so that the wheel body (typically a tire) and the road surface cannot bear such a large load.
The front wheels have no steering function or are inflexible to steer. The traditional semi-trailer type flat car can realize passive steering because of small wheel pressure and the front wheels generally have no steering function, but the heavy flat car has overlarge wheel pressure because of overlarge loading weight, so that the steering function of the front wheels is required to be set in order to ensure flexible steering of the flat car, and no effective means is required to finish steering of the large wheel-pressure wheel set under the condition of not adopting complex technologies such as hydraulic and pneumatic.
The wheel pressure cannot be automatically adjusted. When the single side of the traditional semi-trailer flat car adopts double rows of wheels, the heights of the two rows of wheels cannot be automatically adjusted along with the height change of the ground, so that the wheel pressure of one side of the two rows of wheels is overlarge, and the improvement effect of the double rows of wheels on the carrying capacity is not obvious.
Disclosure of Invention
According to the technical problems that the traditional semi-trailer is small in loading capacity, front wheels are inflexible to steer and wheel pressure cannot be balanced automatically, the heavy-load semi-trailer is provided.
The invention adopts the following technical means:
a heavy duty semi-trailer flatbed comprising:
traction hooks, steering wheels, a flat frame, driven wheels, universal guides, a dragging device, a steering rod and a steering seat;
the flat frame is a supporting frame of the whole equipment, the traction hook is connected with the flat frame through the universal guide, namely the universal guide is fixed with the flat frame, and the traction hook is connected and fixed with the free end of the universal guide;
the universal guide is arranged, so that the traction hook can swing around the universal guide in any direction;
the steering wheel is fixed with the flat frame through a steering seat and is positioned at the end where the traction hook is positioned, the driven wheel is fixed at the bottom of the flat frame and is positioned at the opposite end of the traction hook, and the steering wheel and the driven wheel form a running wheel group which enables the flat frame to run together;
the central spindle of the steering wheel is a cross shaft, two ends of a horizontal shaft of the cross shaft are rotatably provided with wheel bodies, and a vertical shaft which is vertical to the horizontal shaft and the steering seat are rotatably assembled through a rotary bearing, so that the horizontal shaft can rotate around the central axis of the vertical shaft;
the steering rod is a U-shaped frame body formed by two horizontal cross rods at the end part and a middle straight rod, the horizontal cross rods are vertically fixed with the middle straight rod, the middle parts of horizontal shafts of the central core shafts of the steering wheels are fixed with the horizontal cross rods, and further the horizontal cross rods can be driven to rotate in the horizontal shafts by left-right swinging, so that the steering wheels are finally rotated;
the dragging device is of a telescopic rod body structure which can freely stretch and retract, one end of the dragging device is hinged with the rod body part of the traction hook, and the other end of the dragging device is fixed with the middle straight rod of the steering rod; the rod body of the traction hook floats up and down and is offset by the expansion of the traction device, and the left-right swing of the rod body of the traction hook drives the middle straight rod of the steering rod through the traction device so as to finally realize synchronous swing of the steering wheel.
The assembly position of the dragging device ensures that the dragging device is arranged vertically to the horizontal plane.
The invention adopting the technical scheme adopts the working principle that: the flat frame is a supporting frame of the whole equipment, the traction hook is connected with the flat frame through the universal guide, the whole flat car is driven to advance and retreat, the traction hook causes lateral deflection when bearing lateral force, and the set of 'link mechanism' of the steering seat causes steering of the steering wheel through the dragging device, the steering rod and the steering seat, so that automatic steering in the running process of the transfer flat car is realized.
The equipment has stronger capability of adapting to uneven ground. The wheel plane of the towing vehicle and the wheel plane of the flat car are not always on the same plane in the towing process, and the towing hook horizontally swings and simultaneously allows the vertical swing. The universal guide device realizes that the traction hook can swing around the universal guide device in any direction.
The universal guide device creatively adopts a four-pin shaft crossed arrangement and pin shaft external structure, and can swing in any direction of the traction hook by rotating around a horizontal shaft and a vertical shaft crossed by the middle and four pin shafts, so that the traction hook is convenient to detach;
in addition, the polytetrafluoroethylene material is used as an antifriction gasket, so that friction force and noise in the swing process of the traction hook are greatly reduced.
The dragging device is a part of the 'link mechanism' mechanism, and is provided with a set of sliding block mechanism for relative displacement between the dragging hook and the steering rod in the swinging process of the dragging hook in release, and the friction force and noise in the sliding process of the sliding block in the dragging device are reduced by using polytetrafluoroethylene as an antifriction gasket.
In order to improve the bearing capacity of the wheels, the steering wheel and the driven wheel body adopt 'glue hanging' cast steel wheels, the 'glue hanging' treatment increases the contact area between the wheels and the ground, reduces the specific pressure between the wheels and the ground, and prevents the ground from being damaged. Compared with the prior tire wheel, the bearing capacity of the single wheel is greatly improved by 5-8 times. Compared with the traditional single-row wheel arrangement, the double-row wheel arrangement is adopted, and the bearing capacity is improved by 10-16 times.
The following measures ensure the flexible steering of the steering wheel:
1. the 'link mechanism' ensures that the rigid rod formed by the steering seat and the steering wheel in the horizontal direction is consistent with the steering angle of the traction hook 1, and the traction hook in the 'link mechanism' pushes the steering rod to be a set of labor-saving lever, so that the steering flexibility is greatly improved.
2. The steering wheel is a special device with a cross shaft and a rotary bearing, and the device reduces the friction force between the steering wheel and the pallet during steering and ensures the flexible steering of the steering wheel.
The flat car has the capability of automatic equalization of wheel pressure, and is ensured by the following measures:
1. the surface of the wheel body is coated with the adhesive, so that running impact and running resistance are reduced, the wheel can adapt to unevenness of four groups of wheels contacting the ground, and the pressure of four corners is balanced within a certain range.
2. In comparison to conventional double row wheel arrangements, the "spider" arrangement automatically equalizes the wheel pressures of the two rows of wheels when the ground surface contacted by the two rows of wheels in the steering or driven wheel is uneven.
The device is simple and practical, and flexible driving of the heavy-duty flat car can be completed as long as the traction hook of the heavy-duty flat car is pulled on the driving car.
Compared with the prior art, the invention has the following advantages:
1. the structure is simple, and the maintainability is good;
2. the shipment capability is high;
3. the front wheel steering function is flexible;
4. the wheel pressure can be balanced automatically, and the adaptability to uneven ground is strong;
