Description

Technical Field

[0001] The utility model relates to the field of transportation equipment for automobile parts, in particular to a foldable engine transportation tray. Background Technique

[0002] The engine is like the heart of a car. During the production and assembly of commercial vehicles, special transportation trays are used to transport the engine. Columns are provided at the four corners of the transportation tray to limit the position of the engine. The transportation tray can reduce the manual burden on the one hand and protect the engine on the other hand. Since the transportation tray is usually large in size and the columns at the four corners will occupy storage space when not in use, the columns are usually designed as a foldable structure.

[0003] The existing foldable engine transportation rack can refer to the Chinese patent document with the publication number of CN108146777A. The above patent document discloses a foldable engine rack, which mainly includes a metal bottom tray assembly, a leg assembly and a buckle assembly. The two leg assemblies are detachably fixed to the metal bottom tray through the buckle assembly, so that the leg assemblies on both sides are folded and stored towards the center, and the leg assemblies are placed parallel to the surface of the metal bottom tray, so as to save space.

[0004] However, in the above solution, if folding is to be achieved, the height of the legs must be less than half of the length of the metal bottom tray. Therefore, when the height of the legs is increased, the length of the metal bottom tray needs to be increased by twice the height. Although the height occupied by the transportation rack is reduced, the floor area of the chassis is increased. Content of the Utility Model

[0005] In order to expand the height of the column without changing the size of the chassis, the present application provides a foldable engine transportation tray.

[0006] A foldable engine transportation tray provided by the present application adopts the following technical solutions:

[0007] A foldable engine transportation tray includes a chassis and columns. Fixed seats are respectively provided at the four corners of the chassis. The columns are connected to the fixed seats one by one. A rotating shaft is provided on the column. The cross-section of the fixed seat is in a U shape, and the open side is used for the column to rotate. Waist-shaped holes are symmetrically opened on the two side walls of the fixed seat adjacent to the open side. The length direction of the waist-shaped holes is perpendicular to the chassis. Both ends of the rotating shaft are inserted into the waist-shaped holes. The length of the waist-shaped holes is greater than the height of the column after folding. A limiting groove is opened on the top surface of the fixed seat, and a limiting member protrudes from the column. The limiting member is inserted into the limiting groove to limit the rotation of the column.

[0008] By adopting the above technical solution, the column is connected to the fixing seat with a waist-shaped hole through a rotating shaft to realize the folding of the column, and the column is locked by plugging and matching the limiting piece with the limiting groove. The length of the waist-shaped hole is greater than the height of the column after folding, so that two columns with a height not greater than the length of the chassis can be stacked on each other when folded inward, thereby expanding the height of the column without changing the length of the chassis, breaking through the original limitation that the height of the folding column must be less than 1 / 2 of the length of the chassis, and a higher column can provide better lateral protection for the engine to prevent the higher engine from accidentally tipping over.

[0009] Furthermore, it also includes an adjustment component. A support member is detachably fixed on the chassis, and the support member is used to overhead support the engine. The adjustment component is used to adjust the position of the support member on the chassis.

[0010] By adopting the above technical solution, a support member is provided to overhead support the engine, which can prevent the parts at the bottom of the engine from being deformed or damaged due to pressure during transportation. The support member is detachably connected to the chassis and an adjustment component is provided at the same time. The position of the support member on the chassis can be adjusted according to the size, specification and position of the support point of the engine, so that the support member can be adapted to different engines, thereby expanding the scope of application of the device.

[0011] Furthermore, a slide groove is provided on the bottom wall of the chassis, and the adjusting component includes a slider, which is slidably arranged in the slide groove. A positioning hole is provided at a portion of the chassis opposite to the slide groove, and a plurality of positioning holes are arranged at intervals along the length direction of the slide groove. A connecting plate is provided at the bottom of the support member, and a mounting hole is provided on the connecting plate. A slot is provided on the top wall of the slider, and the adjusting component also includes a pin, which passes through the mounting hole and the positioning hole in sequence and then engages with the slot.

[0012] By adopting the above technical solution, a slide groove is specifically opened on the chassis, and a slider with a slot on the top is slidably set in the slide groove. The sliding of the slider facilitates adjustment of the installation position of the support member, and the latch is used to fix the slider and the support member.

[0013] Furthermore, a rope is connected between the latch and the support member.

[0014] By adopting the above technical solution, the provision of the rope can prevent the pin from being lost.

[0015] Furthermore, the rope is a flexible rope, the rope can be twisted around the axial direction, and the pin is threadedly matched with the slot.

[0016] By adopting the above technical solution, the threaded cooperation between the pin and the slot can improve the fixing strength. Compared with iron chains or steel wire ropes, the flexible rope can be freely twisted around its own axis, which facilitates the rotation of the pin.

[0017] Furthermore, a receiving groove is formed on a side wall of the support member, and the receiving groove is used to receive the latch.

[0018] By adopting the above technical solution, providing a storage groove on the side wall of the support to store the pin can avoid the pin and the rope from being entangled and knotted when multiple supports are stacked together, making it easier to store or use the pin and the support in a one-to-one matching manner.

[0019] Furthermore, the positioning hole is a strip-shaped hole.

[0020] By adopting the above technical solution, a plurality of positioning holes can determine the approximate installation position of the support member, and setting the positioning holes as strip holes can fine-tune the position of the support member within a single positioning hole.

[0021] Furthermore, the part of the chassis facing the slider is bulged upward to form a slideway with two ends penetrating therethrough, the slide groove is provided on the inner wall of the slideway, and a handle is provided on the side of the slider facing the end of the slideway.

[0022] By adopting the above technical solution, since the slide groove is set on the bottom wall of the chassis, there is a problem of inconvenience in adjusting the position of the slider. The chassis is raised upward to form a slideway with two ends passing through, which can enable the slider to slide above the surface of the chassis, and a handle is correspondingly provided on the slider, so that the user can push and pull the slider by holding the handle.

[0023] Furthermore, two symmetrical sides of the connecting plate are bent downward to form a bent portion, and the bent portion is attached to the side wall of the slideway.

[0024] By adopting the above technical solution, setting the bent portion to fit the side wall of the slide can improve the fixing strength and stability between the support member and the slide, and try to avoid horizontal slippage of the support member after being subjected to force, thereby enhancing the reliability of the device.

[0025] Furthermore, a permanent magnet is embedded in the bottom wall of the connecting plate, and a magnetic part is provided on a side of the sliding block facing the connecting plate, and the permanent magnet attracts the magnetic part to drive the sliding block to slide.

[0026] By adopting the above technical solution, a permanent magnet is arranged on the connecting plate, and a magnetic part is correspondingly arranged on the slider. When the position of the support part is adjusted, the slider can automatically slide along with the support part under the attraction of the magnetic force.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. By making the length of the waist-shaped hole greater than the height of the pillar after folding, two pillars whose height is not greater than the length of the chassis can be stacked on each other when folded inward, thereby extending the height of the pillar without changing the length of the chassis, breaking through the original limitation that the height of the folded pillar must be less than 1 / 2 of the chassis length. A taller pillar can provide better lateral protection for the engine and prevent a taller engine from accidentally tipping over.

[0029] 2. By providing a support member to support the engine in the air, deformation and damage of the components at the bottom of the engine due to pressure can be avoided during transportation. The support member is detachably connected to the chassis and an adjustment component is provided at the same time. The position of the support member on the chassis can be adjusted according to the size, specification and position of the support point of the engine, so that the support member can be adapted to different engines, thereby expanding the scope of application of the device.

[0030] 3. By raising the chassis upward to form a slideway with two ends connected, the slider can slide above the surface of the chassis, and a handle is correspondingly provided on the slider, so that the user can push and pull the slider by holding the handle, thereby easily solving the problem of inconvenience in adjusting the position of the slider due to the slide groove being located on the bottom wall of the chassis.

[0040] The following is combined with the attached Figure 1-7 The technical solutions of this application are described clearly and completely.

[0041] Embodiment 1

[0042] The embodiment of this application discloses a folding engine transportation tray.

[0043] Referring to Figure 1 , Figure 2 , a folding engine transportation tray includes a rectangular chassis 1 and columns 2. Fixed seats 11 corresponding to the columns 2 one by one are respectively arranged at the four corners of the chassis 1. A kidney-shaped hole 111 with a length direction perpendicular to the chassis 1 is opened on the fixed seat 11. The column 2 is connected to the fixed seat 11 through a rotating shaft 3. The rotating shaft 3 is inserted into the kidney-shaped hole 111, and the rotating shaft 3 can slide up and down along the kidney-shaped hole 111. The length of the kidney-shaped hole 111 is greater than the height of the column 2 after folding. The columns 2 at both ends of the long side of the chassis 1 can be rotated to a horizontal position and stacked up and down.

[0044] Without changing the length of the chassis 1, the height of the column 2 is expanded in this device, breaking through the limitation that the height of the original folding column 2 must be less than 1 / 2 of the length of the chassis 1. The higher column 2 can provide better lateral protection for the engine and prevent the relatively high engine from accidentally tipping over during transportation.

[0045] Referring to Figure 1 , Figure 2 , load-bearing beams are arranged around and at the bottom of the chassis 1, and the load-bearing beams are fixed by welding. In order to improve the stability of the column 2, a triangular steel plate is welded between the bottom of the fixed seat 11 and the load-bearing beam as a diagonal brace. The fixed seat 11 is formed by cutting and cold bending a steel plate. The cross-section of the fixed seat 11 is in a U shape, and the open side faces the long side of the chassis 1. The open part is used for the column 2 to rotate. The two kidney-shaped holes 111 are symmetrically opened on the two opposite side walls of the fixed seat 11 respectively, and both ends of the rotating shaft 3 are inserted into the kidney-shaped holes 111. The column 2 is preferably a square column so that it can be stably placed horizontally after folding. A limit groove 112 is opened on the top surface of the fixed seat 11, and a limiting member 21 protrudes from the outer wall of the column 2. When the column 2 rotates to be vertically upward, the limiting member 21 can be inserted and matched with the limit groove 112, thereby locking the fixed seat 11 and the column 2 and restricting the rotation of the column 2.

[0046] Reference Figure 1 , Figure 3 , a support member 4 is detachably fixed on the chassis 1. In the present embodiment, four support members 4 are respectively installed at the four corners of the chassis 1. The support members 4 jointly support the engine, and the engine is suspended above the chassis 1. The device is also provided with an adjustment component 5, and the adjustment component 5 can adjust the position of the support member 4 on the chassis 1. The overhead support engine can prevent the parts at the bottom of the engine from being deformed and damaged due to pressure during transportation. The support member 4 is detachably connected to the chassis 1 and the adjustment component 5 is provided at the same time. The position of the support member 4 on the chassis 1 can be adjusted according to the size, specification and position of the support point of the engine, so that the support member 4 can be adapted to different engines, thereby expanding the scope of application of the device.

[0047] Reference Figure 3 , Figure 4 The adjustment assembly 5 includes a slider 51 and a latch 52. A slide groove 12 is provided on the bottom wall of the chassis 1. The slider 51 is slidably arranged in the slide groove 12. The slide groove 12 is arranged along the length direction of the chassis 1. A positioning hole 13 is provided at a position of the chassis 1 facing the slide groove 12. A plurality of positioning holes 13 are provided at intervals along the length direction of the slide groove 12. A connecting plate 41 is welded to the bottom of the support member 4. A plurality of mounting holes 411 are provided on the connecting plate 41. The mounting holes 411 are distributed around the support member 4. A slot 511 is provided on the top wall of the slider 51. The size of the slot 511 is consistent with that of the mounting hole 411.

[0048] Reference Figure 5 The sliding of the slider 51 facilitates the adjustment of the installation position of the support member 4. After the slider 51 is slid to the position of a certain positioning hole 13, the latch 52 passes through the installation hole 411 and the positioning hole 13 in sequence and then plugs into the slot 511 to fix the slider 51, the chassis 1 and the support member 4 together. It is preferred to set the positioning hole 13 as a strip hole, so that the position of the support member 4 can be fine-tuned within a single positioning hole 13, thereby improving the adjustment accuracy.

[0049] Reference Figure 3 , Figure 5 A rope 6 is connected between the latch 52 and the support 4, and the provision of the rope 6 can prevent the latch 52 from being lost. In order to improve the fixing strength, the latch 52 is threadedly matched with the slot 511, and the rope 6 is preferably a flexible rope made of fabrics such as hemp rope and cloth rope. Compared with other ropes 6 such as chains and wire ropes, flexible ropes can be freely twisted around the axis, which is convenient for rotating the latch 52 during installation. The side wall of the support 4 is also provided with a storage groove 42. When not in use, the latch 52 is inserted into the storage groove 42, which can prevent the latch 52 and the rope 6 from being entangled and knotted when multiple supports 4 are stacked together, making it more convenient for the latch 52 to be stored or used in a one-to-one matching manner with the support 4.

[0050] Reference Figure 1 , Figure 3 The part of the chassis 1 facing the slider 51 is convex upward to form a slideway 14 with two ends passing through. The slide groove 12 is opened on the inner wall of the slideway 14, and a handle 512 is provided on the side of the slider 51 facing the end of the slideway 14. Since the slide groove 12 is set on the bottom wall of the chassis 1, it is inconvenient to adjust the position of the slider 51. The chassis 1 is convex upward to form a slideway 14 with two ends passing through, so that the slider 51 can slide above the surface of the chassis 1, so that it is convenient for the user to push and pull the slider 51 by holding the handle 512. The two symmetrical sides of the connecting plate 41 are bent downward to form a bending portion 412. The bending portion 412 is attached to the outer wall of the slideway 14, which can improve the fixing strength and stability between the support member 4 and the slideway 14, and try to avoid horizontal slippage of the support member 4 after being subjected to force, thereby enhancing the reliability of the device.

[0051] Except for the rope 6, the other parts of the device are all made of steel, which is beneficial to improving the bearing capacity of the transport pallet.

[0052] Example 2

[0053] The embodiment of the present application discloses a foldable engine transport pallet. The difference between the embodiment 2 and the embodiment 1 is that the structure of the adjustment component 5 is different.

[0054] Reference Figure 6 , Figure 7 , the slide groove 12 is located below the surface of the chassis 1, the slider 51 slides on the back of the chassis 1, and the bottom wall of the connecting plate 41 is embedded with a plate-shaped permanent magnet 7, and the size of the permanent magnet 7 is determined by the bottom surface size of the connecting plate 41. The slider 51 is provided with a plate-shaped magnetic member 8 on the side facing the connecting plate 41, and the size of the magnetic member 8 is determined by the top surface size of the slider 51. When the position of the support member 4 is adjusted, the slider 51 can automatically slide with the support member 4 under the attraction of the magnetic force. After the position is adjusted, the support member 4 and the slider 51 are fixed with a latch 52.

[0055] The above are all preferred embodiments of the present application. Obviously, the embodiments described above are only preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made by ordinary technicians in this field based on the structure, shape, and principle of the present application without making any creative work should be covered within the protection scope of the present application.
