Description

Technical Field

[0001] The invention relates to the technical field of fixing devices for transporting cylindrical goods, and in particular to a fixing pallet and its use, and a fixing method for a steel coil. Background Art

[0002] Some cylindrical goods, especially some heavy-loaded goods such as steel coils, have rolling characteristics and relatively concentrated weight. If they are not properly packed and fixed, they are prone to installation hazards such as concentrated weight and uneven loading. Due to the huge inertia during transportation, improper operation is very likely to cause safety accidents.

[0003] At present, the commonly used loading methods include special box loading, container special bracket loading and general container loading (bulk). Special loading boxes and container special brackets can meet the fixing requirements, but they are single-purpose and can often only be transported one way, with low utilization and correspondingly increased costs. Among them, if special brackets are used in ordinary containers, they are also inconvenient to unload. The above two methods are relatively more widely used abroad, but rarely used in China. At present, the general container loading (bulk) mode is mainly used in China, where steel coils are bulked in containers, or some are directly bulked on the deck of the cabin, railway trucks and the bottom plate of the car, and fixed with wood or profiles. Each transfer requires reloading and fixing, which greatly wastes manpower and material resources and is also prone to safety hazards.

[0004] In the modern logistics industry, containers and pallets play a vital role as "transporters" due to their standardization, modularization and high flexibility. It is particularly necessary to design and develop a logistics pallet that is suitable for general containers, cylindrical cargo loading, and general cargo loading. Summary of the invention

[0005] In response to the problems existing in the prior art, this patent provides a fixed pallet to solve the problems existing in the fixation and transportation of cylindrical heavy-loaded cargo.

[0006] Specifically: the fixed pallet includes a pallet for carrying cylindrical goods and a stopper assembly for preventing the cylindrical goods from shifting on the pallet, the stopper assembly includes a circumferential stopper assembly for preventing the cylindrical goods from circumferentially rolling, and the circumferential stopper assembly includes two circumferential stoppers;

[0007] The circumferential stop member includes a fixed stop seat and a movable stop seat; the distance between the two fixed stop seats of a circumferential stop assembly is fixed; the distance between the two movable stop seats of a circumferential stop assembly is changed by adjusting the relative position between the movable stop seat and the fixed stop seat.

[0008] On the basis of the above scheme, the circumferential stop member also includes a circumferential drive assembly, which includes a limit block, a drive screw and a drive block; the limit block is fixedly connected to or integrally formed with the fixed stop seat; the drive block is fixedly connected to the movable stop seat; the distance between the two movable stop seats of the circumferential stop members that provide stops in opposite directions is changed by changing the relative position between the drive screw and the drive block.

[0009] On the basis of the above scheme, a stop ring is provided on the side of the driving screw away from the movable stop seat, and a thread is provided on the side close to the movable stop seat; the limit block is provided with a sleeve hole for the driving screw to be inserted and rotated freely, and the limit block is provided with a clamping sleeve at the entrance end of the sleeve hole for use with the stop ring; the driving block is provided with a screw hole for use with the thread on the driving screw.

[0010] This patent also provides a method for fixing cylindrical goods, the specific steps are as follows:

[0011] S1: First, according to the size of the cylindrical cargo, the circumferential stop assembly and the axial stop assembly are respectively arranged so that the dimension between the circumferential stop member and the axial stop member is larger than the outer dimension of the cargo;

[0012] S2: Place the goods on the pallet so that the outer cylindrical surface of the cylindrical goods is close to the circumferential stop assembly and the bottom surface is close to the axial stop assembly;

[0013] S3: Adjust the axial stop assembly so that the axial stop seat just contacts the cargo; then adjust the circumferential stop assembly to fix the cargo in the circumference; and then adjust the axial stop assembly to lock the cargo in the axial direction;

[0014] S4: Use straps to secure the goods to the pallet, and use the straps to secure the goods to the pallet along the circumference of the goods through the fixing holes.

[0015] The fixed pallet of this patent can realize the rapid and intensive fixation of steel coils in general container transportation, improve efficiency and reduce material and labor costs; the fixed pallet of this patent is convenient for unloading containers when transporting heavy coils, solving the problem of unloading containers when transporting coils; the stop assembly of the fixed pallet of this patent is easy to disassemble, which not only simplifies the unloading process, but also can remove the stop assembly after transporting the coils, and the pallet can be used to transport other goods, improving the utilization efficiency; if the empty pallet is returned, it can be stacked to reduce space occupancy and reduce costs.

[0033] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0034] Example 1

[0035] Fixed tray, such as Figure 1 and Figure 2 As shown in A, it includes a pallet 1 for carrying cylindrical goods and a stop assembly for preventing the cylindrical goods from moving on the pallet 1, the stop assembly includes a circumferential stop assembly 2 for preventing the cylindrical goods from circumferentially rolling, and the circumferential stop assembly 2 includes two circumferential stop members 2-1; (from Figure 2 A shows two circumferential stop assemblies 2, a1 and a2 show one circumferential stop assembly 2, and a3 and a4 show another circumferential stop assembly 2). The above-mentioned fixed pallet is mainly used to carry cylindrical goods, and "cylindrical goods" refers to heavy material coils such as steel coils, copper coils, and aluminum coils. The following embodiments are also described by taking steel coils as an example.

[0036] Steel coils, also known as coiled steel, are steel materials that are hot-pressed or cold-pressed into a coiled shape that is cylindrical in shape. In order to facilitate storage and transportation, and to facilitate various processing (such as processing into steel plates, steel strips, etc.), current steel coils do not have dedicated fixing devices during transportation, and accidents are prone to occur.

[0037] The fixed pallet provided in the above-mentioned scheme can provide circumferential stops for the steel coil (i.e., prevent the steel coil from rolling), so the circumferential stop assembly 2 includes two circumferential stops 2-1 that provide opposite direction stops for the steel coil, and the circumferential stop 2-1 is used to prevent the steel coil from rolling.

[0038] Since the size of the steel coil carried each time is not fixed, the above solution is difficult to adapt to steel coils of different sizes.

[0039] In order to solve the above problems, Figure 2As shown in A, the circumferential stop member 2-1 of the fixed tray of the present embodiment includes a fixed stop seat 2-11 and a movable stop seat 2-12; the distance between the two fixed stop seats 2-11 of a circumferential stop assembly 2 is fixed (that is, the positions of the fixed stop seat 2-11 and the tray 1 are fixed, and there are many ways to fix the positions of the two, such as directly fixing the fixed stop seat 2-11 and the tray 1 by conventional means such as bolts); the distance between the two movable stop seats 2-12 of a circumferential stop assembly 2 is changed by adjusting the relative position between the movable stop seat 2-12 and the fixed stop seat 2-11.

[0040] by Figure 2 Taking A as an example, the movable stop seats 2-12 of a1-a2 and / or a3-a4 are adjusted so that the distance between the movable stop seats 2-12 of a1 and a2 and / or the distance between the movable stop seats 2-12 of a3 and a4 becomes larger or smaller.

[0041] In one embodiment, the solution to the above-mentioned "the distance between the two fixed stop seats 2-11 of a circumferential stop assembly 2 is fixed" is: the tray 1 uses the tray in Chinese utility model patent: 2021220149921 or 2021220133694, because the tray 1 is provided with a through hole 1-1 (the name in patent 2021220149921 is the first through hole, and the name in patent 2021220133694 is the connecting through hole), such as Figure 3 As shown, a protrusion 2-14 with a shape complementary to the through hole 1-1 is provided at the lower part of the fixed stop seat 2-11 (the protrusion 2-14 and the fixed stop seat 2-11 can be fixedly connected or integrally formed). When in use, the protrusion 2-14 is directly inserted into the through hole 1-1. Because the weight of the steel coil is very large, the fixed stop seat 2-11 does not need to be fixed to the pallet 1 in an additional manner to ensure the relative fixation between the fixed stop seat 2-11 and the pallet 1. Another advantage of this method is that after the steel coil is unloaded from the pallet 1, the circumferential stopper 2-1 can be directly removed from the pallet 1, and the pallets 1 can be stacked to reduce space as much as possible.

[0042] like Figure 1 and 2 As shown in A, the pallet 1 is also provided with fixing holes 1-2. After the steel coil is placed on the fixed pallet, in order to ensure the stability between the pallet 1 and the steel coil, a strap 5 is used to tie the steel coil to the pallet 1 along the circumference of the steel coil through the fixing holes 1-2.

[0043] In a specific embodiment, Figure 4 and Figure 5As shown, the circumferential stop member 2-1 also includes a circumferential drive assembly 2-13, and the circumferential drive assembly 2-13 includes a limit block 2-131, a drive screw 2-132 and a drive block 2-133; the limit block 2-131 is fixedly connected to or integrally formed with the fixed stop seat 2-11; the drive block 2-133 is fixedly connected to the movable stop seat 2-12; the distance between the two movable stop seats 2-12 is changed by changing the relative position between the drive screw 2-132 and the drive block 2-133.

[0044] As a preferred solution, Figure 6 As shown, the driving screw 2-132 is provided with a stop ring 2-1321 on the side away from the movable stop seat 2-12, and a thread (not shown in the figure) is provided on the side close to the movable stop seat 2-12; the limiting block 2-131 is provided with a sleeve 2-1311 for the driving screw 2-132 to be inserted and freely rotated, and the limiting block 2-131 is provided with a sleeve 2-1312 used in conjunction with the stop ring 2-1321 at the entrance end of the sleeve 2-1311 (i.e., the end originally away from the movable stop seat 2-12); the sleeve 2-1312 sleeves the driving screw 2-132 at the stop ring 2-1321, so that the driving screw 2-132 can rotate freely in the sleeve 2-1312 but cannot fall out; the driving block 2-133 is provided with a screw hole 2-1331 used in conjunction with the thread on the driving screw 2-132. When in use, the drive screw 2-132 is rotated, and the drive screw 2-132 idles in the sleeve 2-1312 and the sleeve hole 2-1311, and the drive screw 2-132 is screwed in or out of the screw hole 2-1331. Since the fixed stop seat 2-11 is relatively fixed to the tray 1, and the sleeve 2-1312 prevents the drive screw 2-132 from completely passing through the sleeve hole 2-1311, at this time, the drive screw 2-132 is screwed in or out of the screw hole 2-1331, which drives the movable stop seat 2-12 to approach the fixed stop seat 2-11 or move away from the fixed stop seat 2-11; thereby achieving the increase or decrease of the distance between the two movable stop seats 2-12 of the same circumferential stop assembly 2. Figure 2 As shown in A, during adjustment, two circumferential stop assemblies 2 (a1-a2 and a3-a4) need to be adjusted simultaneously to adapt to steel coils of different sizes.

[0045] The weight of the steel coil is very large, and stability and safety during loading and unloading are very important. For this reason, the relative movement between the movable stop seat 2-12 and the fixed stop seat 2-11 is preferably carried out according to a fixed track. For this reason, as an optimized and implementable solution, Figure 6As shown, a first movable track 2-15 for use with a fixed stop seat 2-11 and / or a second movable track 2-16 for use with a limit block 2-131 are provided at the bottom of the movable stop seat 2-12. Through this structure, when the movable stop seat 2-12 moves, it always moves along the fixed stop seat 2-11 and / or the limit block 2-131. Because the fixed stop seat 2-11 and the pallet 1 are relatively fixed, the stability of the steel coil fixation during loading and unloading is increased.

[0046] like Figure 2 As shown in A, the side of the movable stop seat 2-12 close to the steel coil is a stop surface 2-121, and the stop surface 2-121 is a slope.

[0047] After all, the steel coil is more prone to the risk of circumferential rolling during transportation. The above-mentioned fixed pallet with circumferential stopper 2-1 can form a circumferential stop for the steel coil, effectively preventing the steel coil from rolling during transportation.

[0048] When the above-mentioned fixed tray is in use, Figure 2 As shown in A, at least two circumferential stop assemblies 2 are arranged on the tray 1, wherein a1-a2 is one and a3-a4 is one. A circumferential stop 2-1 may be added between a1 and a3 and a corresponding circumferential stop 2-1 may be added between a2 and a4.

[0049] However, in order to further increase the safety of the fixed pallet fixing the steel coil, based on the above solution, as an optimized implementation scheme, Figure 2 B. Figure 4 , Figure 5 and Figure 7 As shown, the stop assembly also includes an axial stop assembly 3 for providing axial stops for cylindrical goods (such as steel coils), and the axial stop assembly 3 includes two axial stop members 3-1, and the two axial stop members 3-1 are respectively located on both sides of the axial direction of the cylindrical goods. As a simple mode, the axial stop members 3-1 can be directly fixed on the pallet 1 (such as Figure 2 C).

[0050] As an optimized implementation scheme, Figure 3 As shown, a fixing groove 2-122 is provided on the stop surface 2-121 of the movable stop seat 2-12 along the stop direction (axial direction of the cylindrical cargo) provided by the axial stop assembly 3; Figure 2 , Figure 4 , Figure 7 , Figure 8 and Fig. 9As shown, the axial stopper 3-1 includes an axial fixing seat 3-11, an axial stopper seat 3-12 and an axial drive assembly 3-13; the axial stopper seat 3-12 is fixedly connected or integrally formed with the axial fixing seat 3-11; the axial fixing seat 3-11 is arranged in the fixing groove 2-122; the axial drive assembly 3-13 is used to adjust the distance between the axial stopper seats 3-12 of the two axial stoppers 3-1 that provide opposite direction stops for the steel coil. In this way, after the steel coil is placed on the fixed tray, the axial stopper seat 3-12 can be adjusted to clamp the two bottom surfaces of the steel coil by adjusting the axial drive assembly 3-13.

[0051] As a preferred solution, in order to ensure the stability of the axial fixing seat 3-11 when moving in the fixing groove 2-122, as shown in FIG. Figure 3 , Figure 6 and Figure 8 As shown, axial protrusions 2-1221 are arranged on both sides of the fixing groove 2-122, and axial grooves 3-111 for use with the axial protrusions 2-1221 are arranged on both sides of the axial fixing seat 3-11.

[0052] As a specific implementation scheme, Figure 8 and Fig. 9 As shown, the axial drive assembly 3-13 includes a drive fixing seat 3-131 and an axial drive screw 3-132, and the drive fixing seat 3-131 is fixedly connected to the axial fixing seat 3-11 or is integrally formed; the drive fixing seat 3-131 and the axial stop seat 3-12 are respectively arranged on both sides of the movable stop seat 2-12, wherein the axial stop seat 3-12 is located on the outside (i.e., the side close to the bottom surface of the steel coil); the axial drive screw 3-132 is threadedly connected to the drive fixing seat 3-131 and the end of the axial drive screw 3-132 abuts against the movable stop seat 2-12.

[0053] When in use, first rotate the axial drive screw 3-132 to move the axial drive screw 3-132 away from the movable stop seat 2-12, pull the two axial stop seats 3-12 used in conjunction with each other, place the steel coil between the two axial stop seats 3-12, and then rotate the axial drive screw 3-132. Because the axial drive screw 3-132 is threadedly connected to the drive fixing seat 3-131 and the end of the axial drive screw 3-132 is against the movable stop seat 2-12, the axial drive screw 3-132 will drive the axial fixing seat 3-11 to make axial movement along the fixing groove 2-122 (axial direction refers to the axis of the cylindrical steel coil) through the drive fixing seat 3-131, thereby allowing the two axial stop seats 3-12 used in conjunction with each other to clamp and lock the steel coil.

[0054] As another specific embodiment, Fig.10 , Fig.11 and Fig.12 As shown, the axial drive assembly 3-13 includes a drive fixing seat 3-131 and an axial drive screw 3-132. The drive fixing seat 3-131 is fixedly connected to the axial fixing seat 3-11 or is integrally formed. The axial drive screw 3-132 is threadedly connected to the movable stop seat 2-12. The axial stop seat 3-12 is adjusted to be close to or away from the bottom of the steel coil by the depth of the axial drive screw 3-132 rotating into the movable stop seat 2-12.

[0055] Specifically, Fig.12 As shown, the side of the axial drive screw 3-132 away from the movable stop seat 2-12 is sleeved on the drive fixed seat 3-131 (that is, the connection relationship between the axial drive screw 3-132 and the drive fixed seat 3-131 is similar to the connection relationship between the drive screw 2-132 and the limit block 2-131), and as the axial drive screw 3-132 rotates, the position between the axial drive screw 3-132 and the drive fixed seat 3-131 remains unchanged in the direction in which the axial drive screw 3-132 extends, and the axial drive screw 3-132 drives the drive fixed seat 3-131 to approach or move away from the bottom of the steel coil through the depth of the threaded connection between the axial drive screw 3-132 and the movable stop seat 2-12. Fig.12 In the figure, the axial stop seat 3-12 and the driving fixed seat 3-131 are located on the same side of the movable stop seat 2-12. In actual application, they can also be located on both sides of the movable stop seat 2-12 respectively.

[0056] There are many ways to thread the axial drive screw 3-132 and the movable stop seat 2-12. Fig.12 In the figure, a nut 2-133 is used, and the nut 2-133 is fixedly connected to the movable stop seat 2-12. A threaded hole for use with the axial drive screw 3-132 can also be directly opened on the movable stop seat 2-12, which will not be repeated here.

[0057] Because the two bottom surfaces of the steel coil are both planes, as a preferred solution, the surface where the axial stop seat 3-12 of the axial stop member 3-1 contacts the steel coil is perpendicular to the plane where the tray 1 is located.

[0058] As a specific implementation scheme, Figure 2 As shown in FIG. 2B , a fixed tray is provided with two circumferential stopper assemblies 2 on the tray 1, and an axial stopper 3-1 is provided on each circumferential stopper 2-1 of the circumferential stopper assemblies 2, wherein the axial stoppers 3-1 on the circumferential stopper 2-1 on the same side form an axial stopper assembly 3 (as shown in FIG. Figure 2As shown in A, the axial stopper 3-1 provided on a1 and a3 is one axial stopper assembly 3, and the axial stopper 3-1 provided on a2 and a4 is another axial stopper assembly 3. ), that is, two circumferential stopper assemblies 2 and two axial stopper assemblies 3 are provided on a fixed tray.

[0059] As an implementable solution, the fixed stop seat 2-11, the movable stop seat 2-12, the limit block 2-131, the protrusion 2-14 and the axial fixing seat 3-11 can be made of wood, nylon or engineering plastics, etc.

[0060] As an implementable solution, the movable stop seat 2-12 can be integrated (such as Figure 2 A), or it can be assembled in parts (as shown in Figure 3 ).

[0061] Example 2

[0062] This embodiment provides another fixed tray with another axial stop assembly 3. The axial fixing seat 3-11 of the axial stop assembly 3 in embodiment 1 is arranged in the fixing groove 2-122, and when the axial stop is performed, the axial fixing seat 3-11 slides in the fixing groove 2-122.

[0063] like Fig.13 As shown, the axial stop assembly 3 includes two axial stoppers 3-1, and the two axial stoppers 3-1 are respectively located on both sides of the axial direction of the cylindrical cargo. The circumferential stop assembly 2 refers to the content of the embodiment 1.

[0064] like Fig.14 and Fig.15 As shown, the axial stop member 3-1 includes an axial fixing seat 3-11, an axial stop seat 3-12 and an axial driving assembly 3-13; the axial fixing seat 3-11 is fixedly connected to the movable stop seat 2-12; the axial driving assembly 3-13 includes a driving fixing seat 3-131 and an axial driving screw 3-132; the driving fixing seat 3-131 is fixedly connected to the axial fixing seat 3-11 or is integrally formed; one end of the axial driving screw 3-132 is sleeved on the driving fixing seat 3-131 (that is, the connection relationship between the axial driving screw 3-132 and the driving fixing seat 3-131 is similar to the connection relationship between the driving screw 2-132 and the limit block 2-131 in Example 1), and the other end is threadedly connected to the axial stop seat 3-12; the axial stop seat 3-12 is made to approach or move away from the cylindrical cargo by adjusting the threaded connection depth between the axial driving screw 3-132 and the axial stop seat 3-12.

[0065] In this embodiment, the axial fixing seat 3-11 can be an integral whole.

[0066] Example 3

[0067] This embodiment provides a method for fixing cylindrical goods using the above-mentioned fixed pallet, and the specific steps are as follows:

[0068] S1: First, adjust the circumferential stop assembly 2 and the axial stop assembly 3 according to the size of the cylindrical cargo, so that the size between the circumferential stop 2-1 and the axial stop 3-1 is larger than the outer size of the cargo;

[0069] S2: Place the goods on the pallet so that the outer cylindrical surface of the cylindrical goods is close to the circumferential stop assembly 2 and the bottom surface is close to the axial stop assembly 3;

[0070] S3: Adjust the axial stop assembly 3 so that the axial stop seat 3-12 just touches the goods; then adjust the circumferential stop assembly 2 to fix the goods in the circumference; and then adjust the axial stop assembly 3 to lock the goods in the axial direction;
