Description

Technical Field

[0001] The utility model relates to the technical field of transportation, in particular to a special pallet for transporting steel coils in a motor vehicle mode. Background Art

[0002] Existing road transport methods generally use special pallets to transport steel coils, and there are generally two types of special pallets. One is the container pallet, which is modified from the frame chassis of the container and can transport multiple steel coils at a time. During loading and unloading, the container pallet is directly hoisted as a whole, which improves the transportation efficiency. The other is the independent pallet, which can be fixed on the frame chassis and can transport one steel coil at a time, with high flexibility.

[0003] Regardless of the type of specialized pallet mentioned above, all feature a V-shaped groove for placing steel coils. The groove extends perpendicular to the vehicle's forward direction, allowing the steel coils to be placed horizontally within the groove, providing a secure clamping mechanism. However, existing V-shaped grooves only support the coil cross-section at a single point on either side of the groove. This type of support can easily cause the coils to roll out of the groove during sudden braking, posing a safety hazard. Utility Model Content

[0004] The utility model aims to provide a special pallet for transporting steel coils by automobile transportation, which increases the contact area between the steel coils and the steel coil placement grooves, increases the rolling resistance, and reduces the probability of the steel coils rolling out of the steel coil placement grooves.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a special pallet for transporting steel coils by road transport, comprising a base frame detachably mounted on a pallet truck and a front bracket and a rear bracket symmetrically arranged on the base frame front and back, a steel coil placement trough extending left and right is formed between the base frame, the front bracket and the rear bracket, the steel coil is placed horizontally in the steel coil placement trough, the left and right sides of the front bracket and the rear bracket are fixedly connected by connecting plates, thereby closing the left and right sides of the steel coil placement trough; the front and rear side walls of the steel coil placement trough respectively include at least two inclined surfaces with different inclination angles, and each inclined surface is tangent to the steel coil.

[0006] After adopting the above structure, the front and rear side walls of the steel coil placement trough include at least two inclined surfaces with different inclination angles. Due to the change in the angle of the inclined surface, the steel coil placement trough forms an approximately arc-shaped inclined edge; compared with the original V-shaped groove, the support surface is increased, thereby increasing the contact area between the steel coil placement trough and the steel coil, reducing the force between the single support surface and the steel coil, and avoiding the steel coil from being deformed or damaged due to excessive single-point force; when the steel coil rolls inertially due to sudden braking or acceleration, the upper inclined surface gives the steel coil a resistance in the opposite direction, thereby reducing the probability of the steel coil rolling out of the steel coil placement trough; in addition, by increasing the inclination angle of the inclined surface from bottom to top, the side wall height will increase under the premise of the same front and rear width of the top of the steel coil placement trough, so that the rolling resistance of the steel coil will increase exponentially, reducing the probability of the steel coil rolling out of the steel coil placement trough.

[0007] In order to facilitate production and support steel coils of different specifications within a certain range, the front and rear side walls respectively include two inclined surfaces with different inclination angles.

[0008] In order to achieve fast fixed installation and standardization, standard corner fittings are set on the four corners of the chassis, and the standard corner fittings are fixed to the pallet truck through container fixing locks.

[0009] In order to meet the requirements of container pallets and improve lifting efficiency, the chassis is made according to the standard length and width dimensions of the container, and multiple steel coil placement slots are set in parallel on the chassis.

[0010] In order to increase the stability of the steel coil in the steel coil placement trough, rope tighteners are arranged on the front bracket and the rear bracket relative to each other. The oppositely arranged rope tighteners are connected by ropes, and the ropes lock the steel coil in the steel coil placement trough from the top of the steel coil placement trough.

[0011] In order to provide the last line of defense for the steel coil, a front baffle is provided at the front end of the chassis and a rear baffle is provided at the rear end of the chassis. The heights of the front baffle and the rear baffle are made according to the standard height dimensions of the container.

[0012] In order to effectively improve the firmness and reliability of the front baffle and the rear baffle, and enhance the impact resistance of the front baffle or the rear baffle when the steel coil rolls out accidentally, multiple diagonal rods are set between the baffle and the base frame, and between the rear baffle and the base frame.

[0013] In order to meet the flexibility requirements of independent pallets, a steel coil placement slot is set on the base frame.

[0014] In order to facilitate forklift insertion and manual climbing, a forklift opening and climbing handles are provided on the base frame.

[0015] In order to facilitate the lifting of the pallet, lifting holes are symmetrically set on the connecting plates on the left and right sides, and lifting rings can be detachably installed in the lifting holes.

[0016] After adopting the above technical solution, the beneficial effects of the utility model are:

[0017] The utility model discloses a special pallet for transporting steel coils by road, which solves the technical problem that in the prior art, the two side groove walls of the V-shaped groove only adopt single-point support for the cross section of the steel coil. If this support encounters a sudden brake, the steel coil is likely to roll out of the V-shaped groove, which poses a safety hazard. The utility model adds inclined surfaces of multiple angles to the front and rear side walls, thereby changing the original force mode and reducing the probability of the steel coil rolling out of the steel coil placement groove.

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] The orientations mentioned in this specification are based on the orientations of the special pallet for transporting steel coils by road in normal operation of the present invention, and do not limit the orientations during storage and transportation. They only represent relative position relationships, not absolute position relationships.

[0025] Example 1:

[0026] For the convenience of description, in this embodiment, the forward and backward directions of the vehicle are referred to as the front-to-back directions, and the width direction of the vehicle is referred to as the left-to-right direction.

[0027] like Figure 1 、 Figure 2 and Figure 3As shown together, a special pallet for transporting steel coils by road transport includes a base frame 1 that can be detachably mounted on a pallet truck, and a front bracket 2 and a rear bracket 3 that are relatively arranged on the base frame 1 in the front and rear directions. The base frame 1, the front bracket 2 and the rear bracket 3 form a steel coil placement groove extending left and right, and the steel coil 4 is placed horizontally in the steel coil placement groove.

[0028] The front bracket 2 and the rear bracket 3 have the same structure and are only arranged relative to each other in the front and rear directions. Therefore, the following structural description will only be based on the front bracket 2. The contact surface of the front bracket 2 with the steel coil 4 (i.e., the front side wall of the steel coil placement slot) includes at least two inclined surfaces with different inclination angles, and each inclined surface is tangent to the steel coil 4. In this embodiment, it is preferred to include two inclined surfaces with different inclination angles. In actual applications, three or four inclined surfaces with different inclination angles can also be provided, and this embodiment does not limit this. The left and right sides of the front bracket 2 and the rear bracket 3 are fixedly connected by a connecting plate 5, thereby closing the left and right sides of the steel coil placement slot.

[0029] The front and rear side walls of the steel coil placement trough include at least two inclined surfaces with different inclination angles. Due to the change in the angle of the inclined surface, the steel coil placement trough forms an approximately arc-shaped inclined edge; compared with the original V-shaped groove, the support surface is increased, thereby increasing the contact area between the steel coil placement trough and the steel coil 4, reducing the force between the single support surface and the steel coil 4, and avoiding deformation or damage of the steel coil 4 due to excessive single-point force; when the steel coil 4 rolls inertia due to sudden braking or acceleration, the upper inclined surface gives the steel coil 4 a resistance in the opposite direction, thereby reducing the probability of the steel coil 4 rolling out of the steel coil placement trough; in addition, by increasing the inclination angle of the inclined surface from bottom to top, the side wall height will increase under the premise of the same front and rear width of the top of the steel coil placement trough, so that the rolling resistance of the steel coil 4 will increase exponentially, reducing the probability of the steel coil rolling out of the steel coil placement trough.

[0030] The four corners of the chassis 1 are provided with standard corner fittings 11. The standard corner fittings 11 are container standard corner fittings and are fixed to the pallet truck via container fixing locks. In this embodiment, in order to meet the requirements of container pallets and to lift multiple steel coils 4 onto the pallet truck at one time and improve lifting efficiency, the chassis 1 is made according to the standard length and width dimensions of the container, and multiple steel coil placement slots are arranged in parallel on the chassis 1, such as Figure 1 and Figure 2 As shown, three steel coil placement slots are arranged in parallel on the base frame 1. In actual applications, four or five can also be arranged. The symmetry of this embodiment is not limited.

[0031] Rope tighteners 6 are disposed opposite each other on the front bracket 2 and the rear bracket 3. These oppositely disposed rope tighteners 6 are connected by ropes 61, which can be steel wire ropes or nylon ropes. Ropes 61 lock the steel coil 4 from the top of the steel coil storage slot into the steel coil storage slot. To increase the density of ropes 61, multiple groups of rope tighteners 6 are disposed along the left and right sides of the front bracket 2 and the rear bracket 3. In this embodiment, three groups are provided. In actual applications, four groups or another number can also be provided. The symmetry of this embodiment is not a limitation. Multiple groups of ropes 61 form a "net" composed of nylon ropes or steel wire ropes, which firmly secure the steel coil 4 in the "net."

[0032] The existing pallet truck's baffle height is only 1200mm, which is of little use for a steel coil 4 with a diameter of 2500mm. To increase the pallet's risk resistance, a front baffle 71 is provided at the front end of the chassis 1, and a rear baffle 72 is provided at the rear end of the chassis 1 to provide a final safety device for the steel coil 4 if it accidentally falls out of the steel coil storage slot. The heights of the front baffle 71 and the rear baffle 72 are designed based on the standard height dimensions of a container, which has a height of 2438mm. In actual applications, to reduce costs, the front and rear baffles of the container can be directly used. To increase their strength, multiple diagonal tie rods 73 are provided between the front baffle 71 and the chassis 1, and between the rear baffle 72 and the chassis 1. In this embodiment, four diagonal tie rods 73 are provided at the front and rear ends, respectively. The diagonal tie rods 73 effectively enhance the firmness and reliability of the front baffle 71 and the rear baffle 72, and strengthen the impact resistance of the front baffle 71 or the rear baffle 72 when the steel coil 4 accidentally rolls out.

[0033] The chassis 1 is provided with a forklift opening 12 and a climbing handle 13. The climbing handle 13 is evenly arranged on the connecting plate 5.

[0034] In order to facilitate the lifting of the pallet, lifting holes 14 are symmetrically provided on the connecting plates 5 on the left and right sides. Lifting rings are detachably installed in the lifting holes 14, and the lifting operation can be achieved through the lifting rings.

[0035] Example 2:

[0036] In order to meet the flexibility requirements of independent pallets, this embodiment is convenient for assembling pallets of different specifications onto the same pallet truck. Figure 4 As shown, the left and right widths of the chassis 1 in this embodiment are made according to the width of the pallet truck, and a steel coil placement groove is provided thereon. The steel coil placement groove is customized according to the directness of the steel coil 4. Its structure is consistent with the structure in Example 1. The only difference is that the front and rear widths of the chassis 1 are reasonably set, and standard corner fittings 11 are also provided on its four corners. The standard corner fittings 11 adopt standard container corner fittings and are fixed to the pallet truck through container fixing locks.

[0037] During transportation, different pallets can be installed in the front and rear directions of the pallet truck. When lifting, the pallets need to be lifted one by one.

[0038] The utility model discloses a special pallet for transporting steel coils by road, which solves the technical problem that in the prior art, the two side groove walls of the V-shaped groove only adopt single-point support for the cross section of the steel coil. If this support encounters a sudden brake, the steel coil is likely to roll out of the V-shaped groove, which poses a safety hazard. The utility model adds inclined surfaces of multiple angles to the front and rear side walls, thereby changing the original force mode and reducing the probability of the steel coil rolling out of the steel coil placement groove.

[0039] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
