The base 1 and the L-shaped plate 5 are fixedly connected by welding.

The working principle is as follows: when the special support is used, as shown in fig. 1, 2, 3 and 6, the special support is firstly installed on the bottom plate of a trailer for transporting steel coils, and the installation process is as follows; firstly, the anti-skid veins 2 on the bottom surfaces of two bases 1 are attached and placed on a vehicle bottom plate, then the two bases 1 are relatively pushed from the two sides of the vehicle bottom plate, a plurality of inserted rods 3 on one base 1 are respectively inserted into a plurality of corresponding slots 4 on the other base 1, a first inserted rod 32 on one trapezoidal base plate 30 is inserted into a first slot 33 on the other trapezoidal base plate 30 (as shown in figures 1 and 3), then a second threaded rod 27 passes through two adjacent connecting plates 25, then a locking nut 28 is sleeved at the side end of the second threaded rod 27, the locking nut 28 is screwed by a wrench, when the locking nut 28 is screwed, the two bases 1 are close to each other, along with the mutual approach of the two bases 1, two L-shaped plates 5 are respectively hooked on the two side edges of the vehicle bottom plate, at the moment, the handle 8 is screwed, so that the threaded rod 7 drives the clamping plate 9 to ascend until the top surface of the first anti-skid veins 10 tightly props against the bottom, at this moment, the two bases 1 can be firmly fixed on the trailer bottom plate of the transportation steel coil, and the two bases 1 can be detached and assembled, so that the base 1 can be mounted and dismounted conveniently.

After two bases 1 are installed on a chassis for transporting a steel coil, the steel coil is placed between two trapezoidal plates 34 through a hoisting device, and a center hole of the steel coil is aligned to two guide cylinders 51, at the moment, a shaft 52 is inserted into the two guide cylinders 51, and a bolt 56 is inserted at the side end of the shaft 52, the shaft 52 penetrates through the center hole of the steel coil when penetrating through the two guide cylinders 51, at the moment, a rope of the hoisting device is loosened, so that the steel coil is loaded on the shaft 52, the gravity of the steel coil is loaded on the shaft 52, meanwhile, the bottom of the steel coil props against an inclined surface of a trapezoidal backing plate 30, the trapezoidal backing plate 30 is pushed to slowly slide towards the trapezoidal fixing plate 12, at the moment, a spring 31 is compressed, a certain buffering effect is achieved on the gravity of the hydraulic oil steel coil, and simultaneously along with the movement of the trapezoidal backing plate 30, a sliding rod 15 pushes a piston plate 14, and the piston barrel 13, the extruded hydraulic oil is discharged into the hydraulic oil tank 22 through the second connecting hose 24, the process further buffers the thrust of the steel coil pushing trapezoidal base plate 30, due to the arrangement of the first check valve 19 and the second check valve 21, the hydraulic oil in the piston barrel 13 can only be extruded through the small-diameter through hole 17, on the contrary, the hydraulic oil can only enter the piston barrel 13 through the large-diameter through hole 16, at this time, the central hole of the steel coil is loaded on the shaft 52, one side of the bottom of the steel coil is attached to the inclined surface of the trapezoidal base plate 30, the gravity received by the shaft 52 is applied to the racks 36 on the inclined surfaces of the two trapezoidal plates 34 through the two guide cylinders 51, due to the inclined arrangement of the racks 36, the gears 45 on the guide cylinders 51 roll downwards along the inclined surfaces of the racks 36 under the action of gravity, therefore, most of the gravity received by the guide cylinders 51 is dispersed to the downward inclined direction, thereby make most dynamics that guide cylinder 51 received through first slide bar 42 and retaining ring 43 use on the inclined plane of trapezoidal fixed plate 12, the focus of coil of strip is all the time towards the decurrent direction of slope of rack 36 like this, the coil of strip is preceding (to the driver's cabin direction) inertia kinetic energy when can effectually corresponding the transport vechicle emergency brake, can offset the forward inertia kinetic energy of very big partly coil of strip, and because the setting of trapezoidal backing plate 30 and trapezoidal fixed plate 12, also can have and prevent that the coil of strip from rolling to the rear, and through twisting two first in command 40, can paste the coil of strip both sides respectively with two relative one sides of side shield 37, avoid the coil of strip to slide at the axle 52 in the transportation about at will.

When the transport vehicle is in the process of transporting the steel coil and meets the emergency braking condition, because the gravity center of the steel coil always faces the downward inclined direction of the rack 36, the forward inertial kinetic energy (towards the cab) of the steel coil can be effectively corresponded to when the transport vehicle brakes suddenly, a large part of the forward inertial kinetic energy of the steel coil can be counteracted, and the inertial kinetic energy which cannot be counteracted continues to act on the shaft 52, under the action of huge inertial kinetic energy, the steel moving shaft coiling belt 52 moves forwards, when the shaft 52 moves forwards, the guide cylinder 51 can be driven to roll along the upward inclined direction of the rack 36, because the arrangement of the gear 45 and the rack 36 can ensure the stability when the shaft 52 moves, because in the moving process of the shaft 52, the gear 45 is meshed with the rack 36 to drive the guide cylinder 51 to roll, the guide effect is further played on the shaft 52, the situation that the shaft 52 is inclined because the force applied to the two guide cylinders 51 is uneven is avoided, therefore, when the shaft 52 moves along the upward inclination direction of the rack 36 under the inertia effect of the steel coil, the weight of the steel coil is always pressed on the shaft 52, and the downward inclination force of the shaft 52 along the rack 36 is given to the shaft 52, so that a part of the forward huge inertia of the steel coil can be effectively reduced and offset, meanwhile, through the arrangement of the first spring 44, as the shaft 52 moves along the upward inclination direction of the rack 36, the first sliding rod 42 can drive the check ring 43 to synchronously move and simultaneously compress the first spring 44, so that the first spring 44 can further buffer the huge inertia of the forward movement of the steel coil, and as the steel coil moves forward, the trapezoidal backing plate 30 always adheres to the steel coil to synchronously move under the action of the spring 31, as the trapezoidal backing plate 30 moves, the trapezoidal backing plate 30 can synchronously pull the piston plate 14 through the sliding rod 15, when the piston plate 14 is pulled, hydraulic oil in the hydraulic oil tank 22 is sucked into the piston barrel 13 through the first connecting hose 23 and the large-diameter through, because the aperture of the large-diameter through hole 16 is large, the large-diameter through hole will not have too large influence on the moving work of the piston plate 14, hydraulic oil can quickly enter the piston barrel 13 through the large-diameter through hole 16, after the transport vehicle brakes, due to inertia, the steel coil ascending upwards along the inclined plane of the rack 36 inclines, under the weight of the steel coil and the acting force of the rack 36, the steel coil rolls downwards along the front inclined plane of the rack 36 again, at the moment, the steel coil extrudes the inclined plane of the trapezoidal backing plate 30 to push the trapezoidal backing plate 30 to slowly slide towards the trapezoidal fixing plate 12, at the moment, the spring 31 is compressed to play a certain buffering role on the gravity of the steel coil, meanwhile, along with the movement of the trapezoidal backing plate 30, the sliding rod 15 can push the piston plate 14 to slowly extrude the hydraulic oil in the piston barrel 13 through the small-diameter through hole 17, the process further plays a buffering role in pushing, therefore, the situation that the steel coil directly falls off after ascending due to inertia can be effectively avoided, and the steel coil can stably fall off slowly along with the movement of the trapezoidal base plate 30.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
