Description

Technical Field

[0001] The invention relates to the field of clamps, in particular to a self-adjusting steel coil transport vehicle. Background Art

[0002] When transporting steel coils by truck, due to the large mass of the steel coils, it is necessary to prevent the steel coils from moving and rolling due to inertia. At present, the steel coils are usually placed on the cargo board of the truck by their side walls, and blocks are set on the front and back of the side walls of the steel coils to limit the position of the steel coils, and the position of the blocks is fixed. There are some problems with this fixing scheme. The diameter of the steel coils is not uniform, and steel coils that are too large or too small are not firmly fixed. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a self-adjusting steel coil transport vehicle, which can realize the positioning of steel coils with different circular diameters by adjusting the relative distance between two clamping seats, so that the positioning is more stable and the harm caused by inertia during transportation is reduced.

[0004] The technical solution adopted by the present invention to solve the technical problem is: a self-adjusting steel coil transport vehicle, comprising a vehicle body, wherein a cargo plate of the vehicle body is provided with a plurality of steel coil fixing units;

[0005] The steel coil fixing unit comprises a first slide rail, a base, a clamping seat and a hydraulic cylinder;

[0006] The bases are respectively arranged at both ends of the slide rail, the two clamping seats are respectively distributed corresponding to the two bases, and the two clamping seats are respectively slidably matched with the first slide rail;

[0007] The two bases are respectively provided with the hydraulic cylinder, and the output end of the hydraulic cylinder is fixed to the corresponding clamping seat.

[0008] This solution positions the steel coil by means of a clamping seat. Two clamping seats can position a steel coil between them. Since steel coils with different circular diameters require different clamping seat spacings, this solution drives the clamping seat to move by means of a hydraulic cylinder, thereby adjusting the relative spacing between the two clamping seats so that the steel coil can be positioned from below on both sides. This can adapt to steel coils of various specifications and achieve a stable and fixed effect.

[0009] Preferably, the two opposing inner sides of the two clamping seats are provided with oblique inner arc surfaces, which are in contact with and adapted to the steel coil, so as to adapt to the outer arc of the outer wall of the steel coil and avoid the contact between the edges and the steel coil. This structure has a smaller contact area and a smaller pressure, and can prevent the steel coil from being squeezed and deformed by the external edges during transportation.

[0010] Preferably, the side of the clamping seat is provided with a side ear, the side ear is provided with a through hole, the two ends of the connecting rod extend corresponding to the side ears of the two clamping seats respectively, the two ends of the connecting rod are penetrated with the through holes, and the ends of the connecting rod are respectively adapted with bolts. The two clamping seats of the same group can be relatively limited by the side ears and the connecting rod to prevent the steel coil from rolling when the hydraulic cylinder support is unstable, which can achieve the effect of combined limiting.

[0011] Preferably, fixing rods are respectively arranged on the sides of the two clamping seats, the first ends of the fixing rods are connected to the clamping seats, and the second ends of the fixing rods are provided with hanging rods corresponding to the inner holes of the steel coils. The fixing rods can be used to limit the sides of the steel coils to a certain extent.

[0012] Preferably, the ends of the two fixing rods of the same card holder are connected by the same hanging rod, thereby improving the relative connection strength of the two fixing rods of the same card holder.

[0013] Preferably, a second slide rail is transversely arranged on the inner side of the clamping seat, the second slide rail is slidably matched with a slider, the slider is provided with a fastening bolt, the front end of the fastening bolt abuts against the second slide rail, the second slide rail is evenly provided with a plurality of concave holes corresponding to the front end of the fastening bolt, and the slider is hinged with the first end of the fixing rod in multiple degrees of freedom. By sliding the slider on the second slide rail, the width of the steel coil can be automatically adapted to fix steel coils of different widths.

[0014] Preferably, the slider is connected to the first end of the fixing rod via a ring, so that the fixing rod can rotate relative to the slider in multiple directions.

[0015] Preferably, the card holder is respectively provided with a plurality of elastic buffer structures, and the elastic buffer structures include a push pin, a first spring and a brake pin;

[0016] The inner side surfaces of the two clamping seats are provided with first pin holes, the first pin holes are provided with a push pin and the first spring, the outer end of the push pin extends to the outside of the first pin hole, and the first spring pushes the push pin outward;

[0017] The card seat is provided with a second pin hole corresponding to the first slide rail, the brake pin is slidably fitted in the second pin hole, and the outer end of the brake pin points to the first slide rail;

[0018] When the ejector pin slides toward the inner end of the first pin hole, the outer end of the brake pin slides toward the outside of the second pin hole.

[0019] The ejector pin is used to abut against the outer wall of the steel coil. When the vehicle brakes, the steel coil moves forward under the action of inertia. The inertial force of the steel coil will squeeze the outer end of the ejector pin, and then act on the first spring. This process converts part of the kinetic energy of the inertia of the steel coil into the elastic potential energy of the spring. When the vehicle stabilizes, the elastic potential energy of the first spring is slowly released, thereby reducing the impact of the inertia of the steel coil on the card seat.

[0020] At the same time, in this solution, the ejector pin and the brake pin are linked together. The pressure on the ejector pin will act on the first slide rail through the brake pin, thereby increasing the friction between the clamping seat and the first slide rail, preventing the clamping seat from being pushed by the inertia force of the steel coil, reducing the impact force on the hydraulic cylinder, increasing its service life, and making the overall fixation of the steel coil safer.

[0021] Preferably, the inner ends of the first pin hole and the second pin hole are connected to each other, and a second spring is arranged between the first pin hole and the second pin hole. Since the first pin hole and the second pin hole are in different directions, the second spring can be used to better transmit the force of the ejection pin to the brake pins in different directions.

[0022] Preferably, the first pin hole is distributed at the upper part of the inner side surface of the holder. Because the steel coil moves more upward along the inclined surface of the inner side surface of the holder due to inertia force, the first pin hole is arranged at the upper part, which can prevent the steel coil from moving upward to the holder while playing a buffering role.

[0023] Advantages of the present invention:

[0024] By adopting this solution, the relative distance between the two clamping seats can be adjusted to achieve positioning of steel coils with different circular diameters, so that the positioning is more stable and the harm caused by inertia during transportation is reduced.

DETAILED DESCRIPTION

[0030] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. The embodiments are only used to explain the present invention and do not limit the protection scope of the present invention.

[0031] Example

[0032] like Figure 1 As shown, a self-adjusting steel coil transport vehicle comprises a vehicle body 1, wherein a cargo plate 2 of the vehicle body 1 is provided with a plurality of steel coil fixing units;

[0033] The steel coil fixing unit comprises a first slide rail 3, a base 4, a clamping seat 5 and a hydraulic cylinder 6;

[0034] The bases 4 are respectively arranged at both ends of the slide rail, and the two clamping seats 5 are respectively distributed corresponding to the two bases 4, and the two clamping seats 5 are respectively slidably matched with the first slide rail 3;

[0035] The two bases 4 are respectively provided with the hydraulic cylinder 6 , and the output end of the hydraulic cylinder 6 is fixed to the corresponding clamping seat 5 .

[0036] In this solution, the steel coil 19 is positioned by the holder 5. Two holders 5 can position one steel coil 19 between them. Since the steel coils 19 with different circular diameters require different spacings between the holders 5, in this solution, the holder 5 is driven to move by the hydraulic cylinder 6, and then the relative spacing between the two holders 5 is adjusted so that the steel coil 19 can be positioned from below both sides. This can adapt to steel coils 19 of various specifications and achieve a stable and fixed effect.

[0037] The two opposing inner sides of the two clamping seats 5 are provided with oblique inner arc surfaces 7, which are in contact with and adapted to the steel coil 19. This facilitates the adaptation to the outer arc of the outer wall of the steel coil 19, and avoids the contact between the edges and the steel coil 19. This structure has a smaller contact area and a smaller pressure, and can prevent the steel coil 19 from being squeezed and deformed by the external edges during transportation.

[0038] The side of the clamping seat 5 is provided with a side ear 8, and the side ear 8 is provided with a through hole. The two ends of the connecting rod 9 extend corresponding to the side ears 8 of the two clamping seats 5, and the two ends of the connecting rod 9 are penetrated by the through holes, and the ends of the connecting rod 9 are respectively adapted with bolts. The two clamping seats 5 of the same group can be relatively limited by the side ears 8 and the connecting rod 9 to prevent the steel coil 19 from rolling when the hydraulic cylinder 6 is unstable, which can play a combined limiting effect.

[0039] Combination Figure 2 As shown, the sides of the two clamping seats 5 are respectively provided with fixing rods 10, the first ends of the fixing rods 10 are connected to the clamping seats 5, and the second ends of the fixing rods 10 are provided with hanging rods 11 corresponding to the inner holes of the steel coils 19. The fixing rods 10 can limit the sides of the steel coils 19 to a certain extent.

[0040] The ends of the two fixing rods 10 of the same card holder 5 are connected by the same hanging rod 11. The relative connection strength of the two fixing rods 10 of the same card holder 5 is improved.

[0041] A second slide rail 12 is transversely arranged on the inner side of the holder 5, and a slider 13 is slidably matched with the second slide rail 12. The slider 13 is provided with a fastening bolt 14, and the front end of the fastening bolt 14 abuts against the second slide rail 12. The second slide rail 12 is evenly provided with a plurality of concave holes corresponding to the front end of the fastening bolt 14. The slider 13 is hinged with the first end of the fixing rod 10 with multiple degrees of freedom. By sliding the slider 13 on the second slide rail 12, the width of the steel coil 19 can be automatically adapted so as to fix the steel coils 19 of different widths.

[0042] The slider 13 is connected to the first end of the fixing rod 10 via a ring, so that the fixing rod 10 can rotate relative to the slider 13 in multiple directions.

[0043] Combination Figure 3 As shown, the holder 5 is provided with a plurality of elastic buffer structures, each of which includes a top pin 15, a first spring 16 and a brake pin 17;

[0044] The inner side surfaces of the two clamping seats 5 are provided with first pin holes, and the first pin holes are provided with a push pin 15 and the first spring 16. The outer end of the push pin 15 extends to the outside of the first pin hole, and the first spring 16 pushes the push pin 15 outwards;

[0045] The holder 5 is provided with a second pin hole corresponding to the first slide rail 3, the brake pin 17 is slidably fitted in the second pin hole, and the outer end of the brake pin 17 points to the first slide rail 3;

[0046] When the ejector pin 15 slides toward the inner end of the first pin hole, the outer end of the brake pin 17 slides toward the outside of the second pin hole.

[0047] The ejector pin 15 is used to abut against the outer wall of the steel coil 19. When the vehicle brakes, the steel coil 19 moves forward under the action of inertia. The inertial force of the steel coil 19 will squeeze the outer end of the ejector pin 15, and then act on the first spring 16. This process converts part of the kinetic energy of the inertia of the steel coil 19 into the elastic potential energy of the spring. When the vehicle stabilizes, the elastic potential energy of the first spring 16 is slowly released, thereby reducing the impact of the inertia of the steel coil 19 on the card seat 5.

[0048] At the same time, in this solution, the push pin 15 and the brake pin 17 are linked together. The pressure on the push pin 15 will act on the first slide rail 3 through the brake pin 17, so that the friction force of the holder 5 relative to the first slide rail 3 is increased, and the holder 5 is prevented from being pushed under the inertia force of the steel coil 19, thereby reducing the impact force on the hydraulic cylinder 6, increasing its service life, and making the overall fixation of the steel coil 19 safer.

[0049] Preferably, the inner ends of the first pin hole and the second pin hole are connected to each other, and a second spring 18 is provided between the first pin hole and the second pin hole. Since the first pin hole and the second pin hole are in different directions, the second spring 18 can be used to better transmit the force of the ejector pin 15 to the brake pins 17 in different directions. It should be noted that the elastic force of the second spring 18 must be large to prevent the ejector pin 15 from being excessively retracted into the first pin hole.

[0050] Preferably, the first pin hole is distributed at the upper part of the inner side surface of the holder 5. Because the steel coil 19 moves upward along the inclined surface of the inner side surface of the holder 5 when the inertial force moves, the first pin hole is arranged at the upper part, which can prevent the steel coil 19 from moving upward to the holder 5 while playing a buffering role.

[0051] Advantages of the present invention:

[0052] By adopting this solution, the steel coils 19 with different circular diameters can be positioned by adjusting the relative distance between the two clamping seats 5, so that the positioning is more stable and the harm caused by inertia during transportation is reduced.

To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
