Description

Technical Field

[0001] The invention relates to the technical field of bagged cement stacking, and more specifically to a lifting device for bagged cement stacking. Background Art

[0002] Bag cement is one of the commonly used materials in the construction industry. The lifting device for bag cement stacking is a special equipment designed to solve the storage and handling problems of bulk materials such as cement.

[0003] For the transportation of bagged cement, it is very common to use vehicles with a load bucket or load box. These vehicles are usually designed for handling and transporting bulk or bagged materials.

[0004] DumpBody: DumpBody is usually installed on the chassis of a truck and is used to load and transport bulk or bagged materials. When the material needs to be unloaded, the dumpBody can be tilted by hydraulic or mechanical devices to allow the material to slide out of the dumpBody. This design is particularly suitable for scenarios where fast and large-scale unloading of materials is required.

[0005] CargoBox: Unlike a bucket, a cargo box is usually enclosed to protect the material from weather, pollution, and other external factors. The box usually has an openable door or lid to facilitate loading and unloading of materials. For bagged cement, the box can ensure that the cement bags remain dry, clean, and safe during transportation.

[0006] The existing vehicles for transporting bagged cement are mostly vehicles with a load bucket or a load car. The existing bagged cement stacking lifting device has a single function. The common processing method is to lift the bagged cement from top to bottom on the vehicle with the load bucket to stack them in sequence. It cannot be effectively adapted for use when loading a vehicle with a load car. Therefore, it is particularly important to propose a lifting device that can freely adapt to vehicles with load buckets and load cars to load bagged cement. In view of this, we propose a lifting device for stacking bagged cement. Summary of the invention

[0023] The lifting clamp is delivered to the appropriate position of the carrier in the load bucket by adjusting the spatial position and the horizontal lifting adjustment with the crane arm. The cylinder stroke causes the connecting drive arm to rotate with the axial axis of the driving main shaft as the center of the circle, causing the swing main arm to rotate and adjust to separate the bagged cement. At the same time, the cylinder stroke causes the pressure plate to increase the downward force on the bagged cement to reduce the deviation of the bagged cement.

The bagged cement is stacked in the load bucket of the truck from top to bottom in sequence through the horizontal state and the above-mentioned clamping and suspension combined with the lifting mechanical arm; the present invention adjusts the clamping and stacking system to the following state by rotating the fourth movable end of the lifting mechanical arm. Figure 8 In the horizontal state shown, the main arm adjustment mechanism and the movable sub-arm mechanism are in a quasi-right angle state, and the bagged cement is clamped by the main arm adjustment mechanism, and the bagged cement is pressed by the pressing mechanism, and the lifting mechanical arm is used for suspension, and then the fourth movable end of the lifting mechanical arm is rotated and adjusted to adjust the clamping and stacking system to the following Fig. 9 The vertical state shown is then adjusted by adjusting the main arm adjusting mechanism and the movable sub-arm mechanism at the upper end, so that the main arm adjusting mechanism and the movable sub-arm mechanism at the upper end are unfolded and separated from the bagged cement, and then the movable sub-arm mechanism at the lower end is adjusted to rotate and unfold, and the bagged cement is tilted outward in cooperation with the pressing mechanism, and then the main arm adjusting mechanism and the movable sub-arm mechanism at the upper end are adjusted to fold and shrink, and the variable distance mechanism is used to move closer, so that the movable sub-arm mechanism at the upper end is inserted into the comb tooth gap between the lower movable sub-arm mechanisms, and the bagged cement is pushed to slide along the inclined movable sub-arm mechanism at the lower end by real-time adjustment of the fourth movable end of the lifting mechanical arm for tilting and the upper movable sub-arm mechanism for rotation and unfolding, and pushed to the rear door at the rear end of the truck load-bearing car; the functionality of the lifting device is improved through the above-mentioned two manual adaptation operation switching adjustments, and it is adapted to the loading requirements of two different trucks to meet diverse loading requirements.

By adapting the length of the thread groove A and the thread groove B to the sliding distance of the dynamic clamping unit and the rotating base, the rotating base is always located at the center axis position of the fixed clamping unit and the dynamic clamping unit, which is convenient for the operator to adjust the actual operation of the clamping and stacking system, and adapt to the approach movement of the dynamic clamping unit in one of the operation modes, and effectively compress the distance between the dynamic clamping unit and the fixed clamping unit, so as to facilitate the pushing operation of the bagged cement.

[0029] 3. The present invention increases the downward force on the bagged cement by causing the pressure plate to operate through the stroke of the cylinder, causing the bagged cement to deviate during the process of lowering and unloading the two sets of movable sub-arm mechanisms of the truck with a loading bucket, resulting in uneven stacking; and the bagged cement is easily dumped to the outside during the lateral pushing operation of the truck with a load-bearing car, so as to facilitate the lateral pushing operation.
