Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic car unloading machines, in particular to a side-turning hydraulic car unloading machine. Background Art

[0002] Hydraulic platform unloaders are primarily used for the rapid unloading of bulk materials, improving their transport efficiency. They primarily include side-tip and rear-tip hydraulic platform unloaders. The rear-tip hydraulic platform unloader is used for rear-tip unloading. The truck, loaded with bulk materials, is driven onto the rear platform, with the rear of the vehicle positioned at the unloading port. A hydraulic transmission drives the rear platform backward, causing the truck to flip backward, completing the unloading process. Side-tip unloaders are used for side-tip unloading. The truck, loaded with bulk materials, is driven onto the side platform, with the side of the vehicle positioned at the unloading port. A hydraulic transmission drives the side platform sideways, causing the truck to flip, completing the unloading process.

[0003] In the existing technology, common side-tipping hydraulic unloaders often have a protective plate fixed to the flap to increase the rollover angle and improve unloading efficiency. After the unloading vehicle is driven onto the flap, the vehicle's wheels are adjusted to contact the protective plate before continuing the unloading operation. This unloading method requires multiple driving to adjust the vehicle's tire position to ensure that the tires are in close contact with the protective plate. This adjustment process requires experienced drivers and takes a long time, resulting in reduced unloading efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a side-rolling hydraulic unloading machine, which is provided with automatically movable anti-roll side plates on the flip plate. After the vehicle is moved onto the flip plate, the anti-roll side plates can be automatically adjusted close to the vehicle tires without moving the vehicle, thereby providing protection for the truck.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figures 1 to 7 As shown, a side-tipping hydraulic unloading machine includes several flap articulated seats 2 and hydraulic rod articulated seats 4, and the several flap articulated seats 2 and hydraulic rod articulated seats 4 are respectively arranged linearly and parallel to each other, and the flap articulated seats 2 and hydraulic rod articulated seats 4 are fixed on the unloading site, and the fixed position of the flap articulated seat 2 is close to the unloading port of the unloading site; one side of the flap 1 is hingedly matched with the flap articulated seat 2; the other side of the flap 1 is hingedly connected to a first hydraulic rod 3, and the driving arm of the first hydraulic rod 3 is articulatedly matched with the hydraulic rod articulated seat 4.

[0026] A plurality of guide grooves 101 are provided on one side of the flap 1 close to the flap hinge seat 2, and a push plate 5 is slidably provided in the guide groove 101. The push plate 5 extends to the end above the flap 1 and is fixedly connected to the anti-roll side plate 11. The push plate 5 extends to the end below the flap 1 and is hinged to a movable link 6. The movable link 6 is hinged to a fixed link 7 on the side away from the push plate 5, and the fixed link 7 is hinged to the bottom of the flap 1 at one end away from the movable link 6; a second hydraulic rod 9 for driving the fixed link 7 to rotate is also provided at the bottom of the flap 1.

[0027] As the fixed link 7 rotates, the push plate 5, through the movable link 6, moves forward and backward within the guide groove 101. This movement of the push plate 5 simultaneously drives the anti-roll side plates 11. When a truck drives over the flap 1, the anti-roll side plates 11 are adjusted to one side of the truck's tires, providing a positional limit for the truck. This prevents the truck from tipping over, eliminating the need for repeated adjustments to the truck's position. This improves unloading efficiency.

[0028] In this embodiment, Figure 5 and Figure 6 As shown, the driving direction of the second hydraulic rod 9 is perpendicular to the extension direction of the guide slot 101. The movable link 6 and the fixed link 7 are hingedly connected via a hinge shaft 10. The driving link 8 is provided with a keyway hole 801 extending in the same direction as the guide slot 101, and the hinge shaft 10 passes through the keyway hole 801. When the second hydraulic rod 9 drives the fixed link 8 to rotate, the keyway hole 801 drives the fixed link 8 to move and accommodates the horizontal rotational displacement caused by the rotation of the fixed link 8.

[0029] Preferably, one fixed link 8 drives two groups of fixed links 7 to rotate. Figure 5 and Figure 6 As shown, both ends of the fixed link 8 are provided with keyway holes 801, and the two keyway holes 801 are respectively connected to the corresponding hinge shafts 10 of the two sets of fixed links 7. The second hydraulic rod 9 is provided at the bottom of the flap 1, and the driving arm of the second hydraulic rod 9 is connected to the middle part of the driving link 8 via a connecting piece.

[0030] Furthermore, a guide plate 14 is provided on the top of the anti-roll side plate 11. The guide plate 14 is used for transitional unloading of bulk materials. Since after the truck drives above the flap 1, there is still a certain distance between the side of the truck and the unloading port of the unloading site, some of the goods may flow along the truck body and onto the flap 1 during the unloading process. To reduce this phenomenon, a guide plate 14 is provided on the top of the anti-roll side plate 11. The guide plate 14 is close to the unloading port of the side of the truck facing the anti-roll side plate 11, and the other side of the guide plate 14 extends outward and covers the flap 1. In this way, the bulk materials flowing out of the truck first pass through the guide plate 14 and then flow into the unloading port of the external unloading site, avoiding the problem of materials flowing on the flap 1 and requiring secondary cleaning.

[0031] As a specific implementation method, Figure 2 、 Figure 3 and Figure 7As shown, a fixing sleeve 12 is provided on the outer side of the anti-roll side plate 11, and the guide plate 14 is connected to the fixing sleeve 12 via a column 13. The column 13 is welded to the bottom of the guide plate 14 and inserted into the fixing sleeve 12. This plug-in connection facilitates the assembly and disassembly of the guide plate 14. This design is intended to address the problem of some trucks with downward-folding side rails, where the guide plate 14 may interfere with these types of side rails. Therefore, when unloading such trucks, the guide plate 14 can be removed to continue unloading operations, improving the device's applicability.

[0032] It should be noted that this embodiment also includes a hydraulic rod controller for controlling the first hydraulic rod 3 and the second hydraulic rod 9. The above hydraulic rod controller belongs to the existing conventional technology, and its specific setting method is not described in detail here.

[0033] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
