Description

Technical Field

[0001] The utility model relates to the technical field of heavy-duty unloading vehicles, in particular to a floor-standing double-side cantilever heavy-duty mobile unloading vehicle. Background Art

[0002] A heavy-duty dump truck is a large vehicle used to transport bulk materials in mines, ports, construction sites, etc. It is an indispensable means of transportation in the production process, usually with large capacity, high load capacity, strong durability, etc., which can meet the company's needs for fast and efficient transportation of large quantities of materials.

[0003] When unloading, the existing unloading truck needs to flip the hopper so that the material slides out as the hopper angle of the unloading truck is raised to achieve the purpose of unloading. However, as the tilt angle of the hopper increases, the center of gravity of the unloading truck will shift backward, causing the front of the unloading truck to tilt, resulting in high wear and failure rate of components, and frequent maintenance and replacement are required. Utility Model Content

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A floor-standing double-sided cantilever heavy-duty mobile unloading vehicle, comprising an unloading vehicle base, a side wall at the rear end of the unloading vehicle base is provided with an extension slot, the extension slot runs through the left and right sides of the unloading vehicle base, two extension plates are symmetrically arranged on the inner side of the extension slot, the extension plates are slidably connected to the extension slot, a hydraulic cylinder is fixedly installed on the opposite side of the two extension plates, and a grounding plate is fixedly installed on the lower end of the hydraulic cylinder;

[0007] A control mechanism for controlling the relative or opposite movement of the two extension plates is arranged in the extension groove.

[0008] Preferably, the control mechanism comprises two partitions fixedly installed in the extension groove, the partitions are fixedly connected to the extension groove, and the two partitions are rotatably connected with a double-headed screw, and both ends of the double-headed screw are respectively threadedly connected to the two extension plates.

[0009] Preferably, it also includes a driving motor fixedly mounted on the lower side of the unloading vehicle base, the end of the driving motor extending into the extension groove is fixedly mounted with a worm, the middle part of the double-headed screw is fixedly mounted with a worm wheel, and the worm and worm wheel are meshed with each other.

[0010] Preferably, the worm gear is located between two partition plates.

[0011] Preferably, the threads at both ends of the double-headed screw are arranged in opposite directions.

[0012] Preferably, screw holes matching the double-headed screw rods are formed on opposite sides of the two extension plates.

[0013] The utility model has the following beneficial effects:

[0014] 1. Through the design of the control mechanism, since the threads at both ends of the double-headed screw rotate in opposite directions, the two extension plates can move in opposite directions. The extension plates can be unfolded to support the rear end of the unloading vehicle and ensure the stability of the unloading vehicle;

[0015] 2. Through the design of the hydraulic cylinder and the grounding plate, the hydraulic cylinder pushes the grounding plate to contact the ground for support, so as to avoid the center of gravity shifting backwards during unloading, causing the front of the unloading truck to be lifted up.

[0016] In the utility model, a control mechanism is utilized to unfold the extension plate, and then the hydraulic cylinder cooperates with the ground plate to contact with the ground for support, so as to avoid the front of the unloading vehicle being tilted due to the center of gravity shifting backwards during unloading.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0023] Reference Figure 1-Figure 3 A floor-standing double-sided cantilever heavy-duty mobile unloading vehicle comprises an unloading vehicle base 1, a side wall at the rear end of the unloading vehicle base 1 is provided with an extension slot 6, the extension slot 6 runs through the left and right sides of the unloading vehicle base 1, two extension plates 4 are symmetrically arranged on the inner side of the extension slot 6, screw holes matching with double-headed screws 7 are provided on opposite sides of the two extension plates 4, the extension plates 4 are slidably connected with the extension slot 6, hydraulic cylinders 2 are fixedly installed on the opposite sides of the two extension plates 4, and a grounding plate 3 is fixedly installed on the lower end of the hydraulic cylinder 2;

[0024] A control mechanism for controlling the relative or opposite movement of the two extension plates 4 is provided in the extension groove 6. The control mechanism includes two partitions 10 fixedly installed in the extension groove 6. The partitions 10 are fixedly connected to the extension groove 6. A double-headed screw 7 is connected to the two partitions 10 for common rotation. The threads at both ends of the double-headed screw 7 are arranged in opposite directions. The two ends of the double-headed screw 7 are respectively threadedly connected to the two extension plates 4. It also includes a driving motor 5 fixedly installed on the lower side of the base 1 of the unloading vehicle. A worm 8 is fixedly installed at the end of the driving motor 5 extending into the extension groove 6. A worm gear 9 is fixedly installed in the middle of the double-headed screw 7. The worm 8 and the worm gear 9 are meshed with each other. The worm gear 9 is located between the two partitions 10.

[0025] Working principle:

[0026] When the hopper of the unloading truck flips over to unload, the driving motor 5 is driven first, and the output shaft of the driving motor 5 rotates to drive the worm 8 to rotate. Since the worm 8 is meshing with the worm wheel 9, the double-headed screw 7 is rotated. The rotation of the double-headed screw 7 realizes the opposite movement of the two extension plates 4. The extension plate 4 drives the hydraulic cylinder 2 to unfold. After the unfolding is completed, the hydraulic cylinder 2 pushes the ground plate 3 to contact the ground for support, so as to avoid the center of gravity moving backward during unloading, causing the front of the unloading truck to be lifted up.
