Description

Technical Field

[0001] This invention belongs to the field of trailer technology, specifically relating to a factory transfer trailer. Background Technology

[0002] Factory transfer trailers are non-powered transport equipment specifically designed for enclosed environments such as factories and logistics parks. They are typically towed by a tractor or forklift and used for the efficient transport of raw materials, semi-finished products, and finished products. Their core function is to achieve bulk transfer of goods over short distances. They are widely used due to their high load-bearing capacity, flexible operation, and high adaptability. When using existing factory transfer trailers to transport pipe fittings or semi-finished products, the fittings are first stacked on the trailer's pallet and then secured with multiple straps to prevent free movement on the pallet. However, because the straps only contact the outermost layer of fittings, the stacked fittings cannot be too high; otherwise, instability and collapse or slippage may occur. Therefore, using existing trailers to transport pipe fittings results in small single-transport capacity and low operational efficiency. Furthermore, when the main body of the pipe being transported is smooth, it requires a high level of driving experience from the tractor driver to accurately control speed, steering angle, and sudden braking during straight-line and turning maneuvers, in order to minimize the adverse effects of inertia on the stability of the pipe fixed on the pallet. However, due to the special nature of the factory environment, which is not only highly variable and complex, but also involves a large and unpredictable flow of personnel, pipe collapses frequently occur during actual pipe transport, resulting in a relatively high rate of transportation accidents. Summary of the Invention

[0003] The factory transfer trailer provided by this invention can increase the amount of goods transported in a single trip, thereby improving transfer efficiency, and can also prevent pipes from falling off the pallet, thus providing good safety.

[0004] The technical solution adopted by the present invention to solve its technical problem is: a factory transfer trailer, including two limiting plate groups arranged opposite to each other on the pallet of the trailer body, and at least one limiting plate group can move relative to the pallet in the left and right direction.

[0005] Each limited plate assembly includes end plate one, multiple long strip frames, multiple sliders, end plate two, pressure plate, and multiple locking components.

[0006] An end plate is set vertically and has a groove that runs through it from left to right.

[0007] Multiple long strip frames are stacked vertically and placed in a groove, and are matched with end plates by sliding rail structures arranged vertically, so that each long strip frame can move up and down relative to end plates in the groove.

[0008] Each of the elongated frame sections has multiple sliders within its groove 2. These sliders are matched with the elongated frame via sliding rails arranged in the front-to-back direction, allowing each slider to move back and forth relative to the elongated frame within its groove 2. The groove 2 is a through groove, with both the left and right ends of the sliders extending beyond the groove 2. The inward-facing end forms a columnar portion, and the outward-facing end forms a finned portion. Both the columnar portion and the finned portion are at least partially exposed outside the groove 2, or extend outward relative to the left and right ends of the elongated frame.

[0009] End plate two is set vertically and is positioned opposite end plate one on the outside.

[0010] The pressure plate and end plate 2 are matched by a track structure arranged in the left and right direction, so that the pressure plate can move left and right relative to end plate 2, and can move closer to and away from end plate 1.

[0011] Multiple locking components are distributed between the pressure plate and the end plate, which can controllably match the plate surface of the pressure plate facing the end plate with the fins on each slider simultaneously (and in a contact matching state). In the matching state, each slider can be kept fixed relative to the end plate and the long frame. That is, after the plate surface of the pressure plate facing the end plate matches with the fins on each slider, the position of each slider can be kept fixed.

[0012] Optionally, an elastic pad is fixedly provided on the side of the pressure plate facing the end plate. When the locking assembly pushes and pulls the pressure plate to move left and right relative to the end plate, the fin portion provided on the slider can selectively contact and separate from the elastic pad.

[0013] Optionally, the fin portion provided on the slider includes multiple fins arranged vertically alternately.

[0014] Optionally, an annular bladder portion is provided on the outer peripheral surface of the cylindrical portion near the free end. At least in the inflated state, the outer peripheral surface of the bladder portion can protrude radially relative to the outer peripheral surface of the cylindrical portion.

[0015] Optionally, the number of sliders on the various elongated frames within the same defined plate group may be inconsistent or not entirely consistent. It should be noted that the total number of elongated frames on both sides of the defined plate group is consistent, and the number of sliders on the two elongated frames at the same height on the left and right sides of the defined plate group is also consistent; that is, the number of sliders on the two elongated frames at the lowest position is consistent, the number of sliders on the two elongated frames at the second height position is also consistent, the number of sliders on the two elongated frames at the third height position is also consistent, and so on, until the number of sliders on the two elongated frames at the top height position is still consistent.

[0016] Optionally, the number of sliders on each of the elongated frames in the same defined plate group is inconsistent, and gradually decreases from bottom to top. For example, seven sliders can be set on each of the two elongated frames at the lowest position; five sliders can be set on each of the two elongated frames at the second height; four sliders can be set on each of the two elongated frames at the third height; and so on, until one or two sliders are set on each of the two elongated frames at the top height.

[0017] Optionally, a recessed groove is provided on the second end plate, with its end face facing the first end plate. The pressure plate is disposed in the recessed groove and is matched with the inner wall of the recessed groove by a track structure arranged in the left-right direction, so that the pressure plate can move left and right relative to the recessed groove, and one end face of the pressure plate can extend out of the port of the recessed groove and retract into the port of the recessed groove.

[0018] Optionally, vertically extending flange plates are provided on the front and rear side walls of end plate one. Vertically extending flange plates are provided on the front and rear side walls of pressure plate two. Strip-shaped slots communicating with the settling groove one are provided on the front and rear side walls of end plate two. The thickness of flange plate two is less than the width of the strip-shaped slot.

[0019] After the pressure plate is inserted into the sink, the front and rear edge plates 2 can extend out of the strip-shaped slot and are positioned opposite edge plate 1. Multiple locking components are distributed between edge plate 1 and edge plate 2 on the front and rear sides, and can apply force between edge plate 1 and edge plate 2, thereby controllably controlling the simultaneous matching and de-matching of the pressure plate's surface facing end plate 1 with the fins on each slider.

[0020] Optionally, the locking assembly includes a bolt, a spring sleeved on the threaded rod of the bolt, and a nut disposed at the free end of the threaded rod of the bolt.

[0021] Multiple through holes are provided on flange one and flange two, arranged vertically and opposite to each other, for the bolts of the bolt to pass through, connecting flange one and flange two together. At that time, the two ends of the spring can contact the nut of the bolt and the end face of flange two respectively; the nut can press against the end face of flange one.

[0022] Optionally, the limiting plate assembly on one side is fixedly mounted on the slide, and the slide and the pallet are matched by a track structure arranged in the left and right direction. It is also matched with at least one hydraulic telescopic cylinder fixed on the pallet, and can move relative to the pallet in the left and right direction as the cylinder rod of the hydraulic telescopic cylinder performs telescopic movements.

[0023] The beneficial effects of this invention are: it can increase the single transport volume of pipe fittings when transporting them by trailer, thereby improving the transport efficiency; at the same time, it can also prevent pipe fittings from collapsing and falling off the pallet during the transport process, thus helping to reduce the transport accident rate and effectively protect the safety of factory property and personnel.

Detailed Implementation

[0031] The structures, proportions, and sizes illustrated in the accompanying drawings are merely for illustrative purposes and to aid those skilled in the art in understanding and reading the invention. They are not intended to limit the scope of the invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of the invention, should still fall within the scope of the technical content disclosed herein. Furthermore, terms such as "upper," "lower," "front," "rear," and "middle" used in this specification are merely for clarity and not intended to limit the scope of the invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention's implementation.

[0032] like Figures 1 to 6 The illustrated factory transfer trailer includes two limiting plate assemblies arranged opposite each other on a pallet 101 of the trailer body 10. Both limiting plate assemblies on the left and right sides are movable relative to the pallet 101 in the left-right direction, allowing for adjustment of their fixed positions on the pallet 101. This design better accommodates pipe fittings 100 of different lengths during transfer operations, enabling the limiting plate assemblies on both sides to fix the left and right ends of the pipe fitting 100 respectively. In the illustrated scheme, a first slide 20 and a second slide 30 are respectively provided on the left and right sides of the pallet 101. The limiting plate assembly on the left side is fixed to the first slide 20, and the limiting plate assembly on the right side is fixed to the second slide 30. The two slides carry the two limiting plate assemblies and allow them to move left and right relative to the pallet 101. Specifically, groove structures extending in the left and right directions can be provided on the left and right sides of the upper end face of the tray 101, and convex rail structures corresponding to and matching the aforementioned groove structures can be provided on the lower part of the slide 1 20 and the lower part of the slide 2 30, so that the two slides can move linearly relative to the tray 101 in the left and right directions.

[0033] Preferably, both slides (slide 1 20 and slide 2 30) can slide relative to the pallet 101 in the left-right direction. Slide 1 20 is positioned closer to the side of the trailer body 10 that connects with the tractor, and slide 2 30 is positioned closer to the rear end of the trailer body 10. Slide 1 20 is also matched with at least one hydraulic telescopic cylinder 201 fixed to the pallet 101, allowing it to move left-right via the extension and retraction of the cylinder rod. Slide 2 30 is manually adjusted to its left-right position relative to the pallet 101 and is fixed to the pallet 101 with bolts / studs, preventing further relative movement.

[0034] Each of the defined plate assemblies includes an end plate 1, multiple elongated frames 2, multiple sliders 3, a second end plate 4, a pressure plate 5, and multiple locking components 6. The first end plate 1 and the second end plate 4 are fixedly mounted on the first slide 20 or the second slide 30, with a lateral distance between their opposing surfaces. The lateral distance between the first end plate 1 and the second end plate 4 within the same defined plate assembly is controlled between 10mm and 50mm. The first end plate 1 and the second end plate 4 mounted on the first slide 20 can be integrally formed with the body of the first slide 20; similarly, the first end plate 1 and the second end plate 4 mounted on the second slide 30 can also be integrally formed with the body of the second slide 30.

[0035] The end plate 1 is vertically mounted and has a through groove 11 formed on its surface. Vertically extending protruding rails 111 are respectively provided on the front and rear inner walls of the groove 11. (See reference...) Figure 2 , Figure 4 As shown.

[0036] Multiple elongated frames 2 are stacked vertically and disposed in the groove 11, and are respectively matched with the end plate 1 by sliding structures arranged vertically, so that each elongated frame 2 can move up and down relative to the end plate 1 in the groove 11. Therefore, the front and rear end faces of the elongated frames 2 are provided with groove structures corresponding to and matching the vertical convex rails 111, so that each elongated frame 2 can slide independently relative to the end plate 1. It should be noted that, as shown in the figure... Figure 2 The sum of the vertical thicknesses of the multiple elongated frames 2 on the same end plate 1 is less than the vertical height of the groove 11, and the multiple elongated frames 2 need to have a large vertical space / distance relative to the groove 11.

[0037] The groove 11 is in the shape of a square slot, specifically a square slot or a rectangular slot; and preferably the groove 11 is formed into a rectangular slot that is close to a square shape.

[0038] The inner frame of the elongated frame 2 is formed as a through-groove 21, and the through-groove 21 is significantly rectangular in shape, preferably a narrow rectangular slot. Each of the elongated frame 2 has multiple sliders 3 in its through-groove 21, and these sliders 3 are respectively matched with the elongated frame 2 via a sliding track structure arranged in the front-back direction, allowing the sliders 3 to move back and forth relative to the elongated frame 2 within their through-groove 21. See below. Figure 4 As shown, extensions (for) are formed on the upper and lower inner walls of the groove 21 of the elongated frame 2. Figure 4 The horizontal convex rail 22 (in the left-right direction in the view) is provided; correspondingly, a groove structure matching the horizontal convex rail 22 on both sides is provided on the wall surface of the slider 3, so that each slider 3 provided on the same long frame 2 can slide independently relative to the long frame 2.

[0039] Both the left and right ends of the slider 3 extend out of the groove 21, and a columnar part 31 is formed at the inward end of the slider 3, and a finned part 33 is formed at the outward end.

[0040] The second end plate 4 is vertically arranged and positioned opposite the first end plate 1 on its outer side.

[0041] The term "inner" as used above can be understood as the side facing the center of the length of the tray 101; conversely, the term "outer" can be understood as the side facing both ends of the length of the tray 101.

[0042] The pressure plate 5 and the end plate 2 4 are matched by a track structure arranged in the left and right direction, so that the pressure plate 5 can move left and right relative to the end plate 2 4, and can move closer to and away from the end plate 1.

[0043] Multiple locking components 6 are distributed between the pressure plate 5 and the end plate 1, which can simultaneously match the plate surface of the pressure plate 5 facing the end plate 1 with the fin portion 33 on each slider 3, thereby keeping each slider 3 in a fixed state relative to the end plate 1 and the long frame 2. That is, after the plate surface of the pressure plate 5 facing the end plate 1 matches the fin portion 33 on each slider 3, the position of each slider 3 can be kept in a fixed state.

[0044] The number of elongated frames 2 on the left-side limiting plate group is the same as the number of elongated frames 2 on the right-side limiting plate group, and both are shown as 6. This allows the elongated frames 2 on both limiting plate groups to be distributed and arranged opposite each other, as shown in the figure. Figure 1 Meanwhile, the number of sliders 3 on the two elongated frames 2, which are respectively located on the left and right limiting plate groups and are at approximately the same height, is also the same. However, the number of sliders 3 on multiple elongated frames 2 located on the same limiting plate group may be completely different or partially the same, as shown in the example below. Figure 4 .

[0045] An elastic pad 52 is fixedly provided on the surface of the pressure plate 5 facing the end plate 1. When the pressure plate 5 is pushed and pulled by the locking assembly 6 to move left and right relative to the end plate 1, the end of the wing portion 33 provided on the slider 3 can selectively contact and separate from the elastic pad 52, thereby fixing the position of the slider 3 (in vertical space) and preventing it from moving relative to the end plate 1 and the elongated frame 2; and allowing the slider 3 to move and change position in vertical space.

[0046] The fin portion 33 includes a plurality of fins arranged vertically alternately. When the fin portion 33 presses on the elastic pad 52, the fins can compress the elastic pad 52 to produce elastic deformation and sink into the elastic pad 52, preventing the slider 3 from moving freely in vertical space.

[0047] In the technical solution of this application, the relative positions between the limiting plate groups on the left and right sides are adjusted according to the length of the pipe 100 to be transported, that is, the left and right distance between them is adjusted. Generally, the position of the limiting plate group near the rear of the trailer body 10 is adjusted first, that is, the position of the slide block 2 30 is set first and fixed; then the position of the limiting plate group near the end of the trailer body 10 that is connected to the tractor is adjusted, that is, the position of the slide block 1 20 is adjusted again, until the distance between the limiting plate groups on both sides is slightly greater than the length of the pipe 100. Then the loading operation of the pipe 100 is carried out. During this process, the pipe 100 is loaded onto the pallet 101 one by one. First, one end of the pipe 100 is deeply inserted into the column part 31 provided on the slide block 2 30, and after the other end is aligned with the column part 31 on the corresponding slide block 1 20, the pipe 100 is pulled to the left so that both ends of the pipe 100 are respectively inserted into the column parts 31 on the two opposite sliders 3. The pipe 100 is basically arranged in the left and right direction. This operation allows multiple pipe fittings 100 to be stacked from bottom to top, with both ends of each pipe fitting 100 inserted into the corresponding column portion 31, all arranged substantially in the left-right direction. Next, moving the slide block 20 brings the limiting plate assemblies on both sides closer together, ensuring that both ends of each pipe fitting 100 are stably inserted into the corresponding column portion 31. Finally, adjusting the locking components 6 on the limiting plate assemblies on both sides until the positions of each slider 3 are fixed completes the loading operation of the pipe fittings 100.

[0048] By fixing the two ends of the pipe fitting 100 with the column portions 31 arranged opposite to each other, and keeping the vertical spatial position of each column portion 31 fixed, the purpose of safely transferring multiple pipe fittings 100 stacked in multiple layers can be achieved. This application aims to increase the amount of pipe fittings 100 transported in a single trip, improve the transfer efficiency, and prevent the pipe fittings 100 from falling off the pallet 101, thus making the transfer operation of the pipe fittings 100 safe.

[0049] like Figure 1 , Figure 2 , Figure 6 As shown, an annular bladder portion 32 may be provided on the outer peripheral surface of the column portion 31 near the free end. When the bladder portion 32 is fully inflated, its outer peripheral surface protrudes radially relative to the outer peripheral surface of the column portion 31, and can contact the inner wall of the tube 100 inserted into the column portion 31, so as to more firmly fix the end of the tube 100, suppress the impact intensity of the tube 100 during transportation, reduce noise, and protect the outer coating or outer wall surface of the tube 100.

[0050] The externally located fitting (which is connected to the air pump unit) that is connected to the air supply pipe on the bladder body 32 can be fixed on the long frame 2 and extended laterally in the front-back direction. Then, branch pipes extend downward and are inserted into the air supply pipes on each bladder body 32.

[0051] like Figures 2 to 4 As shown, a recessed groove 41 is provided on the end plate 2 4, with one end face facing the end plate 1. A pressure plate 5 is placed in the recessed groove 41 and matches a convex rail structure extending laterally on the inner wall of the recessed groove 41. This allows the pressure plate 5 to move laterally relative to the recessed groove 41, enabling one end face (facing the end plate 1) of the pressure plate 5 to extend outside the port of the recessed groove 41 and retract inside the port of the recessed groove 41, thus switching between matching and de-matching with the fin portion 33 on the slider 3. When the elastic pad 52 is provided on the pressure plate 5, the elastic pad 52 can retract into and extend out of the port of the recessed groove 41, contacting or separating from the fin portion 33. The free end of the fin portion 33 can extend to a position close to the port of the recessed groove 41, as shown in [reference needed]. Figure 3 The fact that the pressure plate 5 is embedded in the end plate 4 helps to reduce the thickness (left-right dimension) of the limiting plate assembly.

[0052] To reduce the weight of the pressure plate 5, a recess 53 can be provided on the end face of the pressure plate 5 opposite to the end plate 1. Meanwhile, in this application, the main bodies of the elongated frame 2 and the slider 3 can both be made of plastic to reduce their weight and facilitate manual lifting for loading operations. Furthermore, a metal shell can be wrapped around the outer layer of the elongated frame 2 and the outer layer of the slider 3 to increase their strength and rigidity while maintaining a relatively low weight. The main bodies of the end plate 1 and the end plate 4 are generally made of metal.

[0053] like Figures 2 to 5 As shown, vertically extending flanges 12 are respectively provided on the front and rear side walls of end plate 1, and the flanges 12 are close to end plate 4. Vertically extending flanges 51 are respectively provided on the front and rear side walls of pressure plate 5. The flanges 51 are detachably connected to the main body of pressure plate 5. The front and rear side walls of end plate 4 are provided with strip-shaped slots 42 that communicate with the recessed groove 41. The length of the strip-shaped slot 42 is along the vertical direction, and the width is along the left and right direction, forming a narrow and elongated through-hole structure. The thickness (left and right dimension) of flange 51 is smaller than the width of the strip-shaped slot 42.

[0054] After the pressure plate 5 is inserted into the settling groove 41, the edge plates 51 on the front and rear sides can extend forward and backward to the outside of the strip-shaped slot 42, respectively, and are oriented opposite to the edge plate 12. (See also...) Figure 2 , Figure 3 The greater the difference between the thickness of the second edge plate 51 and the width of the strip-shaped slot 42, the greater the stroke of the pressure plate 5 relative to the second end plate 4 in the left-right direction.

[0055] Multiple locking components 6 are evenly distributed between the first edge plate 12 and the second edge plate 51 on the front and rear sides. The locking components 6 can apply force between the first edge plate 12 and the second edge plate 51, and can controllably switch the pressure plate 5 towards the end plate 1 and the fin portion 33 on each slider 3 to a state of simultaneous matching and a state of simultaneous dematching.

[0056] like Figure 2 , Figure 3 As shown, the locking assembly 6 includes a bolt 61, a spring 62 sleeved on the screw of the bolt 61, and a nut 63 disposed at the free end of the screw of the bolt 61.

[0057] like Figures 2 to 5 As shown, multiple through holes are provided on the first flange 12 and the second flange 51, arranged vertically and opposite to each other, for the bolt of the bolt 61 to pass through, thereby connecting the first flange 12 and the second flange 51 together. At this time, both ends of the spring 62 can contact the nut of the bolt 61 and the end face (the side facing away from the first flange 12) of the second flange 51, respectively; the nut 63 can press against the end face (the side facing away from the second flange 51) of the first flange 12.

[0058] See Figure 4 , Figure 5Multiple vertically alternating through holes are provided on the first rim plate 12, and multiple vertically alternating through holes are also provided on the second rim plate 51. When the first rim plate 12 and the second rim plate 51 are arranged opposite each other, the multiple through holes on the first rim plate 12 can be connected to the multiple through holes on the second rim plate 51 in a one-to-one correspondence. Between each pair of mutually connected through holes, a locking assembly 6 is respectively arranged, and the screw of the bolt 61 therein passes between the two mutually connected through holes, connecting the first rim plate 12 and the second rim plate 51 together. Tightening the nut 63 (in conjunction with the elastic force of the spring 62) can push and pull the pressure plate 5 to move in the left and right direction. The spring 62 provides an elastic preload on the second rim plate 51 at all times, which not only ensures that the pressure plate 5 and the fin portion 33 are firmly connected and matched, but also buffers the inertial impact in the left and right directions. In conjunction with the elastic pad 52 structure, it can better disperse / dissipate the lateral inertial impact load from the pipe fitting 100, thereby improving the overall ability of the pressure plate 5 to withstand lateral inertial impact and further enhancing the safety of the transfer operation.

[0059] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Many aspects of the present invention can be improved without departing from the overall concept. Those skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
