[0042] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0043] It should be understood that although the terms upper, middle, lower, top, end, etc. appear in this article to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish elements from each other for easy understanding, and are not used to define any direction or order limitation.

[0044] like Figure 1-10 As shown, a foldable, damage-resistant transport vehicle comprises a frame assembly and a limit assembly, wherein the frame assembly comprises an upper frame 1, a side frame 2 and a lower frame 3 which are spliced ​​to each other, and the upper frame 1, the side frame 2 and the lower frame 3 are spliced ​​to each other to form an integral transport frame;

[0045] The limiting assembly includes a vertical limiting module 4 arranged between the upper frame 1 and the lower frame 3, and a lateral limiting module 5 rotatably arranged on the side frame 2. The vertical limiting module 4 and the lateral limiting module 5 include a plurality of flexible clamping units. The hatch cover is limitedly connected with the flexible clamping units, so that the hatch cover can cope with elastic bounce during transportation. The plurality of flexible clamping units separate a plurality of clamping spaces in the front-to-back direction. The lateral limiting module 5 releases the hatch cover in the front-to-back direction by rotating.

[0046] The side frame 2 includes an upper tube body 2.1, a lower tube body 2.2, and a locking frame 6 connecting the upper tube body 2.1 and the lower tube body 2.2, the locking frame 6 is used to connect and limit the upper tube body 2.1 and the lower tube body 2.2 during the transportation of the hatch cover, the upper tube body 2.1 is detachably arranged on the locking frame 6 toward the other upper frame 1 in the lateral direction, and the upper tube body 2.1 is slidably arranged on the locking frame 6 in the vertical direction, so that the upper tube body 2.1 can be vertically separated from the interference of the lower tube body 2.2, so that when the transfer vehicle is unloaded, the upper frame 1 can be removed to make the upper tube body 2.1 and the lower tube body 2.2 rotate relative to each other to achieve a folding effect, thereby facilitating the overall logistics transportation of the transfer vehicle.

[0047] like Fig.10 As shown, in other embodiments, a polyurethane brush 8 is provided in the clamping space along the limiting direction of the hatch cover to allow the hatch cover to elastically bounce in the clamping space.

[0048] like Figure 3 As shown, as a further implementation of the locking frame 6, a vertically arranged slide groove 6.1 is provided on the locking frame 6, and a latch 7 is provided at the bottom of the upper tube body 2.1 and penetrates the slide groove 6.1 along the front-back direction, and the latch 7 passes through the locking frame 6 and the upper tube body 2.1.

[0049] Specifically, the locking frame 6 is arranged in a concave shape and covers the rear part of the upper tube body 2.1 and the lower tube body 2.2, and the locking frame 6 is arranged to be open toward the other upper frame 1 laterally. Under normal conditions, the upper tube body 2.1 is vertically abutted against the lower tube body 2.2, and the latch 7 is located at the bottom of the slide groove 6.1. The locking frame 6 is supported on the back of the upper tube body 2.1 and the lower tube body 2.2, so as to keep the two in a fixed position. When folding is required, the upper frame 1 is first removed, and then the latch 7 is pulled out, the upper tube body 2.1 is slid upward to leave the interference position, and then the upper tube body 2.1 is rotated toward the side frame 2 on the other side to realize the folding of the upper tube body 2.1, so as to reduce the transportation volume of the transfer vehicle in an empty state, which is convenient for long-distance transportation.

[0050] The upper frame 1 includes side fixing rods connecting the left and right side frames 2 in the lateral direction. There are two side fixing rods arranged in the front-to-back direction. An upper fixing rod fixed in the front-to-back direction is arranged between the two side fixing rods.

[0051] Preferably, a shelf block 14 is provided between the two laterally opposite lower tube bodies 2.2, the shelf block 14 is provided with a groove, and the spacing between the two shelf blocks 14 matches the length of the side fixing rod of the upper frame 1, so that the upper frame 1 can be stored in a folded state, which is beneficial to the empty transportation of the transfer vehicle.

[0052] Furthermore, the lower frame 3 has side storage spaces at both ends in the front-rear direction for accommodating the side fixing rods, and a middle storage space is provided in the middle of the lower frame 3 for accommodating the upper fixing rods, thereby realizing the folding and storage of the transfer vehicle.

[0053] like Figure 2 As shown, as a further implementation of the lateral limit module 5, the lateral limit module 5 includes a rotating shaft 5.1 extending in the front-to-back direction, and a connecting sleeve 5.8 and a plurality of side clamping plates 5.2 fixed on the rotating shaft 5.1, one end of the rotating shaft 5.1 is connected to an operating rod 5.3 for driving its rotation, and a lateral clamping space 5.4 is separated between the two side clamping plates 5.2, and the lateral clamping space 5.4 limits the hatch cover in the front-to-back direction.

[0054] Among them, the side clamping plate 5.2 refers to a flexible clamping unit. Under normal circumstances, the side clamping plate 5.2 rotates to a horizontal position, and the two sides of the hatch cover are clamped in the lateral clamping space 5.4 of the two side clamping plates 5.2. When it is necessary to take out or feed materials to the hatch cover, the operating rod 5.3 is manually rotated to drive the side clamping plate 5.2 to flip upward to a vertical state, thereby releasing the hatch cover in the front and rear directions for the hatch cover to be taken out.

[0055] Specifically, a lateral fixing rod 5.5 fixed along the front-to-back direction is provided in the middle and upper part of the upper tube body 2.1, and the lateral fixing rod 5.5 is used for fixing and installing the lateral limiting module 5. The rotating sleeve is fixed on the lateral limiting module 5. The operating rod 5.3 is L-shaped, and the operating rod 5.3 abuts against the lateral fixing rod 5.5 when the side clamping plate 5.2 is locked, and one end of the operating rod 5.3 extends out of the lateral fixing rod 5.5.

[0056] like Figure 6 As shown, as a further explanation of the lateral snap-in space 5.4, the lateral snap-in space 5.4 is configured to converge from the inside to the outside, so that the side of the hatch cover can be smoothly placed in the lateral snap-in space 5.4. At the same time, this method is also convenient for matching with the outer contour shape of different hatch covers.

[0057] Among them, the side clamping block includes an arc clamping surface 5.6 and a flat clamping surface 5.7 in the front-to-back direction, so as to form a lateral clamping space 5.4 between the two side clamping blocks spaced apart in the front and rear directions. The arc clamping surface 5.6 enables the contour of the hatch cover to play a guiding role when it is inserted, thereby facilitating the smooth placement of the hatch cover.

[0058] from Figure 1and Figure 4 It can be seen that as a further implementation of the vertical limit module 4, the vertical limit module 4 includes an upper card plate 4.1 and a lower card plate 4.2 arranged on the upper frame 1 and the lower frame 3 along the front-to-back direction. The upper card plate 4.1, the lower card plate 4.2 and the side card plate 5.2 together constitute a flexible card unit. The upper card plate 4.1 is provided with an upper card space 4.3, and the lower card plate 4.2 is provided with a lower card space 4.4. The upper card space 4.3 and the lower card space 4.4 are staggered in the front-to-back direction. This arrangement can adapt to the contour curvature of the hatch cover to improve the limiting stability. On the other hand, this method can also place the hatch cover in an inclined posture to facilitate the hatch cover to be placed in the card space.

[0059] The polyurethane brush 8 may also be arranged on the upper clamping space 4.3 and the lower clamping space 4.4.

[0060] Specifically, the lower card plates 4.2 are symmetrically arranged on both sides, and the upper card plate 4.1 is set between the lower card plates 4.2 and located above the center line of the lower card plates 4.2. Through the above improvements, a triangular support is formed between the upper card plates 4.1 and the lower card plates 4.2, further improving the stability of the hatch cover.

[0061] like Figure 3 As shown, specifically, the lateral clamping space 5.4 is respectively provided with a first flexible stopper 9 and a second flexible stopper 10 at the upper and lower parts corresponding to the side clamping block, and the first flexible stopper 9 and the second flexible stopper 10 extend in the lateral clamping space 5.4 with respect to the front-rear direction, and the first flexible stopper 9 and the second flexible stopper 10 are spaced apart in the left-right direction to abut against the lateral contour of the hatch cover.

[0062] Optionally, the first flexible stopper 9 and the second flexible stopper 10 are used to further follow the contour of the hatch cover to ensure the position of the hatch cover and to prevent the hatch cover from bouncing and abrasion during transportation.

[0063] Preferably, the first flexible stopper 9 and the second flexible stopper 10 are both in plate shape, and polyurethane brushes 8 are arranged thereon, so as to further improve the flexible abutment of the hatch cover and the wear of the contact position.

[0064] In other embodiments, a side stop bar 11 is provided between the side card plate 5.2 and the upper card plate 4.1. The side stop bar 11 is located on the outside of the side card plate. The stop bar is used to limit the hatch cover to an extreme position to prevent the hatch cover from detaching laterally when the transfer vehicle collides.

[0065] Specifically, the utility model also provides a manual operation space for the transfer vehicle, wherein the lower frame 3 includes a left bottom frame 3.1 and a right bottom frame 3.2, the side frames 2 are respectively fixed on the outer sides of the left bottom frame 3.1 and the right bottom frame 3.2, and the lower frame 3 is fixed on the inner sides of the left bottom frame 3.1 and the right bottom frame 3.2, and a manual operation space is separated between the left bottom frame 3.1 and the right bottom frame 3.2, wherein the manual operation space is specifically located between the two lower card plates 4.2, so that the manual operation space is located in the center position of the transfer vehicle, which is convenient for operators to operate each card connection space.

[0066] An operating platform 12 is provided at the bottom of the manual operation space.

[0067] like Figure 8 As shown, in other embodiments, in order to prevent the operating rod 5.3 from rotating due to vibration and impact during transportation, which would affect the stability of the hatch cover loading, a stop assembly 13 is provided at both ends of the operating rod 5.3. The stop assembly 13 includes a sleeve 13.1 formed on the operating rod 5.3, a spring 13.2 supported at one end of the sleeve 13.1, and a gear sleeve 13.3 fixed on the lateral fixing rod 5.5.

[0068] Further integration Fig. 9 As shown, specifically, there are relatively arranged step portions 13.4 between the rotating shaft and the sleeve body 13.1, and both ends of the spring 13.2 abut against the step portions 13.4, and the opposite ends of the rotating sleeve and the sleeve have extended edges 13.5 shielded on the outside of the spring 13.2 to prevent the radial movement of the spring 13.2, and an engaging portion 13.6 is provided at one end of the sleeve away from the spring 13.2, and the gear sleeve 13.3 is arranged on the rotating shaft 5.1 on a side corresponding to the engaging portion 13.6 of the sleeve. Under normal circumstances, the spring 13.2 presses the sleeve toward one side of the gear sleeve 13.3, so that the engaging portion 13.6 is engaged with the teeth on the end face of the gear sleeve 13.3, thereby limiting the rotation of the rotating shaft. When it is necessary to rotate the lateral limit assembly, it is necessary to manually push the sleeve and the operating rod 5.3, thereby compressing the spring 13.2, so that the engaging portion 13.6 is relatively away from the gear sleeve 13.3.

[0069] As a fixing method of the gear sleeve 13.3, one side of the gear sleeve 13.3 has a limit sleeve 13.7 sleeved on the lateral fixing rod 5.5 and the rotating shaft 5.1, and a nut 13.8 for locking the limit sleeve 13.7 is provided at the end of the lateral fixing rod 5.5, thereby fixing the gear sleeve 13.3 to the end of the rotating shaft 5.1.

[0070] The above-mentioned clamping spaces refer to the upper clamping space 4.3, the lower clamping space 4.4 and the lateral clamping space 5.4, and the polyurethane brush 8 can be arranged in the upper clamping space 4.3, the lower clamping space 4.4 and the lateral clamping space 5.4 respectively.

[0071] The above-mentioned flexible card connection unit refers to the side card plate 5.2, the upper card plate 4.1 and the lower card plate 4.2.

[0072] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
