[0066] like Figures 1 to 10 As shown, in one embodiment, the present invention provides a powered folding arm crane platform vehicle suitable for a shore-side unloading platform, the powered folding arm crane platform vehicle suitable for a shore-side unloading platform comprises a chassis vehicle 1, a jacking mechanism assembly 2 at both ends, and a folding arm crane 4;

[0067] A support platform 3 is provided on the chassis vehicle 1;

[0068] Both ends of the chassis 1 are provided with a lifting mechanism assembly 2 to achieve free and independent lifting, and one end is also provided with a hydraulic system 5;

[0069] The knuckle boom crane 4 is arranged at the other end of the chassis vehicle 1 .

[0070] In this embodiment, a powered folding arm crane platform vehicle suitable for shore-side unloading platforms is provided. The powered folding arm crane platform vehicle is mainly composed of a chassis vehicle 1, a jacking mechanism assembly 2, a support platform 3, a folding arm crane 4, a hydraulic system 5, etc. The folding arm crane is used to assist in erection and withdrawal operations. The hydraulic system of the powered folding arm crane platform vehicle is provided with a quick connector, which is used to provide power to the support platform trailer connection, or to provide mutual rescue between powered support platform vehicles.

[0071] In actual application, the folding arm crane 4 is used to place the horizontal deck at both ends of the jacking mechanism assembly 2, and then not only adjust the jacking mechanism assembly 2 to adapt to the height of the ground, but also help solve the technical problem of the lack of a mobile platform for shore-side unloading platforms in the prior art.

[0072] In one embodiment, the chassis vehicle 1 includes a frame structure 1.1 and a suspension assembly 1.2, and a steering system 1.3;

[0073] The suspension assembly 1.2 is arranged at both ends of the frame structure 1.1;

[0074] The steering system 1.3 is installed at both ends of the frame structure 1.1 to enable the suspension assembly 1.2 to achieve steering.

[0075] The chassis 1 is mainly used for carrying the upper body and providing short-distance maneuvering function; it adopts a hydraulically driven multi-axle flatbed vehicle structure, and is mainly composed of a frame structure 1.1, a suspension assembly 1.2, a steering system 1.3, a stabilizing leg 1.4, etc.

[0076] In one embodiment, the suspension assembly 1.2 includes a suspension structure, a luffing cylinder, a wheel set, and a drive motor.

[0077] The suspension assembly 1.2 is mainly composed of the suspension structure, luffing cylinder, wheel set, drive motor, etc., and can be adjusted in height. When in the load-carrying state, the suspension is in a low position, and the lower edge of the tire is lower than the frame structure; when in the driving state, the suspension is in a neutral position, and the lower edge of the tire is higher than the frame structure. When encountering uneven ground, it can automatically adjust between the neutral position and the high position to adapt to different terrain conditions.

[0078] Each suspension is set up with dual tires and driven by dual motors, and the drive motor has the function of driving brake.

[0079] In one embodiment, stabilizing legs 1.4 are respectively provided at both ends of the frame structure 1.1 and can move up and down to support the chassis vehicle 1.

[0080] In one embodiment, the frame structure 1.1 includes a support frame 1.1.1 and left and right platforms 1.1.2, and a fixing bracket 1.1.3;

[0081] The supporting frame 1.1.1 is a truss structure;

[0082] The left and right platforms 1.1.2 are arranged at both ends of the supporting frame 1.1.1;

[0083] The fixed bracket 1.1.3 is arranged on the left and right platforms 1.1.2, and is lifted and lowered by the jacking mechanism assembly 2.

[0084] The frame structure 1.1 is mainly composed of a central support frame 1.1.1, left and right platforms 1.1.2, fixed brackets 1.1.3, etc. The left and right platforms are welded to the fixed brackets for mounting the suspension and the stabilizing legs, and the fixed brackets are welded to form a whole through the central support frame, and the power station assembly is mounted on the left platform.

[0085] In one embodiment, the lifting mechanism assembly 2 includes a sprocket assembly 2.1 and a chain 2.2, as well as a lifting cylinder 2.3 and a chain fixing seat 2.4;

[0086] The sprocket assembly 2.1 is suspended above by a fixed bracket 1.1.3;

[0087] The chain 2.2 is wound around the sprocket assembly 2.1;

[0088] The extended end of the cylinder diameter of the lifting cylinder 2.3 is fixed to the fixed bracket 1.1.3 to realize the lifting and lowering of the top structure;

[0089] The chain fixing seat 2.4 is arranged on the fixing bracket 1.1.3.

[0090] The lifting mechanism assembly 2 is used to lift the support platform to adjust the height of the trestle channel. It adopts chain transmission and is mainly composed of a sprocket assembly 2.1, a chain 2.2, a lifting cylinder 2.3, a chain fixing seat 2.4, etc. In addition, when the channel is erected and the equipment being supported is unloaded, the lifting mechanism also plays a role in load transmission. The force transmission process is as follows: the load acts on the support platform; the load is transferred to the chain and sprocket through the connecting support between the support platform and the chain; the load is distributed to the lifting cylinder through the sprocket crossbeam, and finally transmitted to the deck surface through the fixed bracket on the platform vehicle.

[0091] In one embodiment, the steering system 1.3 is driven by the drive motor to form different independent wheel group orientations.

[0092] In one embodiment, the orientation includes an eight-shaped turn, front wheel steering, rear wheel steering, oblique driving, lateral driving, turning in circles, and a reset mode.

[0093] like Figure 7 As shown, the front wheel set is tilted to one side and has different rotation angles, and the rear wheel set is tilted in the opposite direction on the same side, and the wheel sets on the same side form an "eight" arrangement;

[0094] When the front wheels are turned, the front wheel set is arranged to face forward, and the rear wheel set is inclined to one side.

[0095] When the rear wheels are turned, the rear wheel set is arranged to face forward, and the front wheel set is tilted to one side.

[0096] Drive diagonally, with the front and rear tilted to the same side.

[0097] When traveling transversely, the front and rear wheel sets are perpendicular to the traveling direction.

[0098] The front wheel set and the rear wheel set rotate in circles on the spot, with the two sides of the front wheel set and the rear wheel set tilted in opposite directions, so that the front wheel set and the rear wheel set form an inwardly opened figure eight arrangement.

[0099] The power support platform vehicle has a multi-mode all-wheel steering function. By using a swing cylinder as a steering device, a single-bridge ±90° steering is achieved. The vehicle's steering modes include eight-shaped steering, front / rear wheel steering, oblique driving, lateral, in-situ circle, reset and other modes. The steering mode is selected by the handle (button). When steering, the center lines of the axes of all steering mechanisms intersect at the same common point to ensure smooth steering of the towing device.

[0100] For example, the steering function is mainly used when turning. When ordinary vehicles turn, the rear wheel is the center of the circle and the length of the vehicle is the radius. For example, a 12m long vehicle needs a large area of ​​R12m to turn. However, our vehicle, because the wheel set has a multi-mode steering function, the wheel set can turn around, almost turning around on the spot. The vehicle is 12m long and can turn around within a range of D12m.

[0101] Furthermore, in narrow places, U-turns are not allowed and you can move directly sideways.

[0102] In one embodiment, the stabilizing leg 1.4 comprises a transversely extending beam and an adjustment support, wherein the transversely extending beam can be extended and retracted to both sides, and the height of the support can be adjusted by arranging the adjustment support at the end thereof.

[0103] The platform vehicle serves as a pier for the trestle channel. When unfolded, it has a relatively high height. Considering the lateral stability of the channel, laterally deployable stabilizing legs are provided at the front and rear ends of the platform vehicle to serve as lateral supports for the platform vehicle, thereby improving the overall stability.

[0104] The support platform 3 is an important part of the trestles along the shore. It is a direct load-bearing component and adopts an orthogonal plate-beam structure. Four sets of rollers are respectively arranged on the left and right sides of the support platform for guiding and limiting the height when lifting. Two pairs of connecting ear plates are respectively arranged at the front and rear ends of the support platform for connecting the springboard and the channel board.

[0105] The powered folding arm crane platform vehicle is equipped with a folding arm crane at the front end of the platform vehicle to assist in the erection and removal of the gangway and channel board.

[0106] The platform vehicle is a carrier of the shore-side unloading platform on the one hand, and is used to adjust the horizontal height of the shore-side unloading platform on the other hand.

[0107] In one embodiment, the present invention further provides a control method for a powered folding arm crane platform vehicle for unloading a platform by a bank, based on the powered folding arm crane platform vehicle for unloading a platform by a bank, the control method comprises:

[0108] Moving the powered folding arm crane platform vehicle to a predetermined position;

[0109] The height of the jacking mechanism assemblies 2 at both ends is continuously adjusted through the electrical control system 6 to achieve a horizontal state at the top and support the horizontal plate at the top of the shore-side unloading platform.

[0110] Among them, the horizontal plate is overlapped between the top of the jacking mechanism assembly 2, and multiple platform vehicles are set. After being set at intervals, the horizontal plates are overlapped in between in turn. Each platform vehicle will provide a stable base platform, and adjust the horizontal state of the horizontal plate so that vehicles can drive normally on it.

[0111] Beneficial effects:

[0112] The shore-side unloading platform and operation method provide a self-protecting unloading channel that can be constructed at multiple angles; it can adapt to high tide scenarios, and the height difference adjustment does not interrupt the unloading process, as well as the principles and operation methods of this solution.

[0113] (1) Possessing self-support function: It can maneuver on its own, has crab-walking function, and is equipped with auxiliary operation devices to assist in completing the erection and removal of the channel.

[0114] (2) Strong site adaptability: The platform vehicle is equipped with a height-adjustable suspension. When in transport mode, the suspension is between the middle and high positions. When encountering side damage or uneven ground, the suspension height can be automatically adjusted to adapt to the ground conditions. When in the through state, the suspension is retracted to the low position, and the wheel group height is lower than the platform vehicle frame structure, so the wheel group does not participate in the force. In addition, the front and rear of the support platform vehicle are equipped with stabilizing legs to adapt to uneven ground.

[0115] In an emergency, without relying on external equipment, the unloading channel can be quickly built relying only on the equipment itself, that is, it is based on self-protection.

[0116] The above embodiments are only exemplary embodiments of the present invention and are not intended to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present invention.
