Description

Technical Field

[0001] This utility model relates to the field of unloading auxiliary devices, and in particular to a mobile hydraulic tipping device. Background Technology

[0002] With the increasing demand for bulk material trucks, the need for unloading auxiliary devices is also growing. Hydraulic tipper unloading devices can achieve rapid unloading and centralized processing, avoiding excessive dust generation during unloading. However, installing hydraulic tippers requires excavating foundation pits in the ground to accommodate hydraulic cylinders and other servo mechanisms. If the hydraulic tippers need to be used in different locations, multiple sets need to be installed, increasing construction intensity and costs. Therefore, it is necessary to improve the hydraulic tipper to a mobile type, allowing for flexible use at different unloading locations.

[0003] Furthermore, the material carts are driven into the hydraulic tipper in reverse, which can easily cause the carts to tilt during the process, resulting in the rear wheels of the carts being misaligned after parking. Traditional hydraulic tippers would prompt the driver to drive the carts out and reposition them precisely. This repeated stopping and starting leads to high energy consumption and low work efficiency. Utility Model Content

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example

[0015] like Figure 1-14 As shown: A mobile hydraulic tipping device includes a mobile platform 1 and a lifting tipping plate 2. The mobile platform 1 and the lifting tipping plate 2 are hinged at one end and open at the other end. The mobile platform 1 includes a mobile frame 3. A front moving wheel 4 and a rear moving wheel 5 are provided on the mobile frame 3. A main oil cylinder 6 is provided between the front moving wheel 4 and the rear moving wheel 5. A guide plate 7 is provided at the front end of the mobile frame 3. The lifting flap 2 includes a flap support 21, guardrails 22 are provided on the left and right sides of the flap support 21, and a connecting frame 23 is provided on the outside of the guardrails 22 and in the middle of the flap support 21. The connecting frame 23 is hinged to the main oil cylinder 6 at the bottom and a gantry frame 8 is provided above it. A wheel stop device 9 is provided at the rear end of the flip plate bracket 21, and a hydraulic station 10 is provided below the movable frame 3.

[0016] Both the front moving wheel 4 and the rear moving wheel 5 are hydraulic moving wheels, including a driving hydraulic cylinder 41. The driving hydraulic cylinder 41 is connected to the moving frame 3 through a mounting base 42. The piston rod of the driving hydraulic cylinder 41 is connected to a swing rod 43. One end of the swing rod 43 is hinged to the end of the piston rod of the driving hydraulic cylinder 41, and the other end is hinged to the mounting base 42. A moving wheel 44 is provided below the swing rod 43.

[0017] The wheel stop device 9 includes a wheel stop frame 91, which extends upward through the flip plate bracket 21. A wheel stop cylinder 92 is connected to the lower part of the wheel stop frame 91, and the lower end of the wheel stop cylinder 92 is connected to the flip plate bracket 21.

[0018] The wheel stop device 9 includes two groups, each group including four independent wheel stop devices 9.

[0019] The mobile frame 3 is a ramp-type mobile frame, and its slope gradually increases from front to back.

[0020] The front moving wheel 4 and the rear moving wheel 5 are symmetrically arranged on the moving frame 3, and the wheel stop device 9 is symmetrically arranged on the flip plate bracket 21.

[0021] The working principle and process of this utility model are as follows: First, the piston rod of the drive hydraulic cylinder 41 extends, driving the swing arm 43 to extend downwards, which in turn drives the moving wheel 44 to extend out of the moving frame 3, lifting the moving frame 3 from the ground. A traction device is installed at the bottom of the moving platform 1. By dragging the traction device with a tractor or loader, the hydraulic tipping device is moved to the working position as a whole. The piston rod of the drive hydraulic cylinder 41 retracts, driving the swing arm 43 to retract upwards, which in turn drives the moving wheel 44 to retract the moving frame 3. The moving frame 3 slowly falls until it is stably placed in the working position.

[0022] The material cart reverses and drives past the guide plate 7 towards the lifting platform 2. Once the material cart is fully inside the lifting platform 2, the main hydraulic cylinder 6 starts working, raising the lifting platform 2 from an inclined state to a horizontal state. The material cart continues to reverse and stops when the rear wheels 11 are in the working position of the wheel stop device 9.

[0023] The hydraulic cylinder 92 extends upward, pushing the wheel stop frame 91 to rise. Once the top of the wheel stop frame 91 is higher than the radius of the rear wheel 11 of the material cart, the hydraulic cylinder 92 stops, and the wheel stop frame 91 effectively locks the rear wheel of the material cart.

[0024] Open the rear door of the truck bed, and the main hydraulic cylinder 6 continues to operate, raising the lifting flap 2 from a horizontal position, causing the material inside the truck bed to tilt downwards and be unloaded. During the unloading process, depending on the material, a vibrator can be installed on the outside of the truck bed to assist in unloading, or a high-pressure air gun can be used to blow the material down.

[0025] The material cart reverses into the lifting platform 2, which can easily cause the cart to tilt during the process, resulting in the rear wheels 11 of the material cart being tilted after parking. A traditional lifting platform 2 would prompt the driver to drive the material cart out and park it precisely again.

[0026] This utility model's wheel stop device 9 includes two groups, each group comprising four independent wheel stop devices 9, i.e., the wheel stop devices 9 are installed in a separate manner. The wheel stop devices 9 are arranged from left to right as A, B, C, and D, as shown below. Figure 6 As shown. After the rear wheels deflect, the parking state is as follows. Figure 7 As shown, the wheel stops at points A and C cannot extend, while the other two wheel stops can extend normally. Parking status as Figure 8As shown, the rear wheels 11 of the material cart are not precisely aligned with the wheel stop devices, but the four wheel stop devices 9 (A, B, C, and D) can still extend normally to achieve the function of stopping the cart. This avoids the material cart repeatedly driving in and out, improving unloading efficiency.
