[0001] This utility model relates to a tilting crane and a tilting method, specifically to a vehicle-mounted segmented tilting crane, belonging to the technical field of vehicle-mounted tilting equipment. Background Technology

[0002] Vehicle-mounted tilting gantry is used for the transfer of boats from the water surface to the vehicle platform during water-to-land transitions. Existing vehicle-mounted gantry uses a single tilting method, which causes a significant shift in the boat's center of gravity during the tilting process, posing a safety hazard; moreover, the space required for a large-scale tilting is excessive. Utility Model Content

[0003] In view of this, the present invention provides a vehicle-mounted segmented tilting hanger, which has a segmented tilting gantry hanger and a folding arm tilting frame, and can solve the above-mentioned technical problems.

[0004] The technical solution of this utility model is: a vehicle-mounted segmented tilting frame, comprising: a gantry frame, a folding arm tilting frame, a frame tilting cylinder, and a folding arm tilting cylinder;

[0005] The head of the gantry hanger is provided with double ears and connecting pins for connecting with the head ear plate of the tray, and the tail is hinged to the head of the folding arm tilting frame.

[0006] The lifting frame tilting cylinder is used to push the gantry lifting frame to tilt around its hinge point with the head of the folding arm tilting frame;

[0007] The tail of the folding arm tilting frame is hinged to the rear crossbeam of the trailer; the folding arm tilting cylinder is used to push the folding arm tilting frame to tilt around the hinge point with the rear crossbeam of the trailer.

[0008] As a preferred embodiment of this utility model: the head of the folding arm tilting frame extends towards the side where the gantry-shaped hanger is located with two connecting ears, and a crossbeam A is connected between the two connecting ears. The two connecting ears are inclined downward relative to the gantry-shaped hanger. The cylinder end of the hanger tilting cylinder is hinged to the crossbeam A between the two connecting ears, and the piston end is hinged to the crossbeam B of the head of the gantry-shaped hanger.

[0009] As a preferred embodiment of this utility model, two hanger tilting cylinders are arranged side by side between the crossbeam A and the crossbeam B.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0024] This embodiment provides a vehicle-mounted segmented tilting gantry, which adopts a segmented tilting scheme using a gantry gantry and a folding arm tilting frame. This can solve the problem of excessive space required for the vehicle-mounted gantry to tilt over a large range when a boat is being transferred from the water surface to the vehicle platform, thus enabling a low center of gravity for the boat to be transferred between water and land.

[0025] like Figure 1 and Figure 2 As shown, the tilting frame includes: a gantry-shaped frame 1, a folding arm tilting frame 2, a frame tilting cylinder 3, and a folding arm tilting cylinder 4;

[0026] The portal frame 1 is composed of box beams, and the head of the portal frame 1 ( Figure 1 and Figure 2 The left end of the portal frame 1 is provided with a pair of double ears and connecting pins that connect to the head ear plate of the pallet (the pallet is used to carry boats), and the tail is provided with a connecting ear for connecting to the folding arm tilting frame 2. The portal frame 1 is hinged to the head of the folding arm tilting frame 2 through the connecting ear.

[0027] The head of the folding boom tilting frame 2 extends forward (to the side where the gantry crane 1 is located) with two connecting lugs. A crossbeam A is connected between the two connecting lugs, and the connecting lugs are inclined downward relative to the gantry crane 1. The cylinder end of the crane tilting cylinder 3 is hinged to the crossbeam A between the two connecting lugs, and the piston end is hinged to the crossbeam B at the head of the gantry crane 1. Thus, the crane tilting cylinder 3 is inclined downward relative to the gantry crane 1.

[0028] As an example, two hanger tilting cylinders 3 are arranged side by side between beams A and B.

[0029] When the piston end of the lifting cylinder 3 extends, it pushes the gantry lifting frame 1 to rotate around the hinge point with the head of the folding arm lifting frame 2, realizing the first stage of flipping (flipping upward and forward). The gantry lifting frame 1 can flip relative to the folding arm lifting frame 2 by 0 to 120 degrees.

[0030] The folding boom tilting frame 2 is composed of a box-shaped beam. A connecting plate 21 is provided at the lower rear end of the folding boom tilting frame 2 for hinged connection with the connecting lug on the rear crossbeam 5 of the trailer. A folding boom tilting cylinder 4 is installed on each side of the outer side of the crossbeam of the folding boom tilting frame 2. The piston end of the folding boom tilting cylinder 4 is hinged to the connecting lug located in the middle of the outer side of the corresponding side of the box-shaped beam of the folding boom tilting frame 2, and the cylinder body end is hinged to the connecting lug at the front of the trailer (e.g., ...). Figure 1 As shown, the articulated boom tilting cylinder 4 has an inclined angle relative to the articulated boom tilting frame 2 to push the articulated boom tilting frame 2 to tilt. When the piston end of the articulated boom tilting cylinder 4 extends, it pushes the articulated boom tilting frame 2 to rotate around the hinge point of its connection with the connecting lug on the trailer's rear crossbeam 5, realizing the second stage of tilting. The articulated boom tilting frame 2 can tilt relative to the trailer from 0 to 100°.

[0031] During use, the limit states of the gantry crane 1 and the folding boom tilting frame 2 are determined based on the positions of the boat in the water and the vehicle. Then, under the limit states, the dimensions of each connecting lug and connecting beam are adjusted to avoid interference. Furthermore, when determining the limit states based on the positions of the boat in the water and the vehicle, the height of the lifting point connecting lugs (i.e., the connecting lugs where the gantry crane connects to the support lugs) should be kept as low as possible.

[0032] like Figure 3 As shown, the process of segmented flipping using this vehicle-mounted segmented flipping frame is as follows:

[0033] First, connect the two ears of the gantry hanger 1 to the ear plate of the tray head using a pin. Then, start the hanger tilting cylinder 3 to push the gantry hanger 1 to rotate around the hinge point with the head of the folding arm tilting frame 2 by a set angle. At this time, the head of the gantry hanger 1 tilts upward and forward. When the gantry hanger 1 tilts to the limit position (i.e., the set angle), the tray is at the highest position.

[0034] Then, the folding arm tilting cylinder 4 is activated, pushing the folding arm tilting frame 2 to rotate around the hinge point connecting it to the crossbeam 5 at the rear of the trailer at a set angle. During this process, the gantry crane 1 and the pallet are tilted forward and downward until the bottom of the front end of the pallet touches the ground; at this time, the folding arm tilting frame 2 is tilted to its limit position.

[0035] Although the present invention has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
