[0002] Gantry cranes (including portal cranes) are widely used for lifting and moving operations in factories, docks, and other cargo distribution centers. Common gantry cranes primarily move by laying pre-laid tracks on the ground, generally operating within a fixed area and unable to be moved to other locations unless completely reinstalled, disassembled, and reassembled – a very cumbersome process. When the site is large and the goods are scattered, multiple machines are required, resulting in significant capital investment and low utilization.

[0003] How to conveniently and quickly realize the relocation of gantry cranes is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0055] As shown in the figure, an embodiment of the present invention provides a folding gantry lifting device, including a folding gantry 1 and a lifting device 2;

[0056] The folding gantry 1 includes a frame 11, a frame flipping mechanism 12, and multiple legs 13 and a leg rotating mechanism 14;

[0057] The frame 11 is formed by splicing two fixed beams 111 and two folding beams 112. The folding beams 112 are parallel to each other, and the folding beams include a first support beam 1121 and a second support beam 1122 that are hinged to each other.

[0058] The frame flipping mechanism 12 is used to provide power so that the first support beam 1121 and the second support beam 1122 fold or unfold each other.

[0059] The support leg 13 is hinged to the frame 11, and the support leg rotation mechanism 14 is used to provide power to rotate the support leg 13.

[0060] The lifting device 2 is installed on the folding gantry 1 and is used for lifting operations.

[0061] To address the problems existing in the prior art, this application provides a folding gantry crane device, including a folding gantry 1 and a lifting device 2. The folding gantry 1 is the lifting and bearing mechanism, and the lifting device 2 is the hoisting operation mechanism, mainly used for lifting and transferring objects. The folding gantry 1 includes a frame 11, a frame flipping mechanism 12, multiple outriggers 13, and an outrigger rotating mechanism 14. By using the frame flipping mechanism 12 to fold the first support beam 1121 and the second support beam 1122 of the folding beam, the area occupied by the frame 11 can be reduced by half. By using the outrigger rotating mechanism 14 to rotate the outriggers 13 and retract the outriggers, the folding gantry crane device can be conveniently and quickly retracted and transported when it needs to be moved, solving the problem of fixed operating sites and difficult relocation of conventional gantry cranes. Furthermore, it can be deployed independently after being transported to the field, demonstrating strong environmental adaptability.

[0062] Furthermore, the current practice of transferring highly dangerous materials such as explosives in the field mainly relies on truck cranes, which poses a safety risk and is prone to tipping over when overloaded or unevenly loaded. The folding gantry crane device provided by this invention has mobile operation capabilities and ensures stability during transfer operations. In addition, after being unfolded, the folding gantry crane device provided in this application can also be used as a field repair cabin by covering it with a tarpaulin, allowing for the repair and maintenance of damaged vehicles.

[0063] The outriggers 13 are preferably provided in four, six or more configurations.

[0064] Preferably, the frame flipping mechanism 12 includes a flipping power source 121, a first connecting rod 122, and a second connecting rod 123;

[0065] One end of the first link 122 is hinged to the first support beam 1121, and the other end is hinged to the second link 123 at hinge point A. The other end of the second link 123 is hinged to the second support beam 1122.

[0066] One end of the flipping power source 121 is hinged to the first link 122 and the second link 123 at hinge point A, and the other end is hinged to the fixed beam 111.

[0067] The preferred frame flipping mechanism 12 includes a flipping power source 121, a first connecting rod 122, and a second connecting rod 123. One end of the first connecting rod 122 and the second connecting rod 123 are hinged to each other (the hinge point is named hinge point A), and the other end is hinged to the first support beam 1121 and the second support beam 1122, respectively. At the same time, one end of the flipping power source 121 is hinged to the fixed beam 111, and the other end is hinged to hinge point A. When the flipping power source 121 operates, its power output end extends, increasing the distance between the two ends of the flipping power source 121, thereby pushing the first connecting rod 122 and the second connecting rod 123 to move. Power is transmitted through the quadrilateral linkage mechanism composed of the first connecting rod 122, the second connecting rod 123, the first support beam 1121, and the second support beam 1122, causing the second support beam 1122 to rotate around its hinge point with the first support beam 1121 (named hinge point B), thereby unfolding the folding frame. Conversely, when the power output end of the flipping power source 121 is retracted, the folding frame can be folded together.

[0068] The tilting power source 121 preferably uses a hydraulic cylinder. During installation, the cylinder barrel clevis can be hinged to the fixed beam 111, and the cylinder piston rod clevis can be hinged to hinge point A.

[0069] Preferably, each support leg 13 is provided with a support leg rotation mechanism 14, one end of which is hinged to the support leg 13 and the other end is hinged to the fixed beam 111.

[0070] A single outrigger rotation mechanism 14 can be used to control the rotation of multiple outriggers 13, or they can be configured separately. Preferably, each outrigger 13 rotates through a corresponding outrigger rotation mechanism 14. The outrigger 13 itself is hinged to the frame 11, and one end of the outrigger rotation mechanism 14 is hinged to the outrigger 13, while the other end is hinged to the fixed beam 111. When the outrigger rotation mechanism 14 extends or retracts, it can push or pull the outrigger 13 to rotate around the hinge point where it is hinged to the fixed beam 111.

[0071] The outrigger rotation mechanism 14 preferably uses a hydraulic cylinder, with the cylinder barrel end hinged to the fixed beam 111 and the piston rod end hinged to the outrigger 13.

[0072] Preferably, the outrigger 13 includes a base section 131, a telescopic section 132, and an outrigger telescopic mechanism 133. The base section 131 is sleeved on the outer periphery of the telescopic section 132, and the telescopic section 132 extends and retracts relative to the base section 131 under the drive of the outrigger telescopic mechanism 133.

[0073] The outrigger rotation mechanism 14 is hinged to the outer wall of the base section 131.

[0074] Preferably, the outrigger 13 is telescopic, providing a higher working height when extended and maintaining a small footprint when retracted. Height adjustment addresses the fixed working range of conventional gantry cranes, offering greater flexibility. Specifically, the outrigger 13 includes a base section 131, a telescopic section 132, and an outrigger telescopic mechanism 133. The base section 131 is fitted around the telescopic section 132, which extends and retracts relative to the base section 131 under the drive of the outrigger telescopic mechanism 133. The outrigger telescopic mechanism 133 can be a hydraulic cylinder and is located within the base section 131 and the telescopic section 132.

[0075] When the outrigger 13 is telescopic, the outrigger rotation mechanism 14 is hinged to the outer wall of the base section 131, so the extension and retraction of the outrigger 13 does not affect the operation of the outrigger rotation mechanism 14.

[0076] Preferably, the lifting device 2 includes a mobile trolley 21, a lifting mechanism 22, a mobile trolley frame 23, a first translation mechanism 24, and a second translation mechanism 25.

[0077] The lifting mechanism 22 is mounted on the mobile trolley 21 and is used for lifting operations;

[0078] The mobile trolley 21 is slidably mounted in the mobile trolley frame 23, and the first translation mechanism 24 is used to provide power to drive the mobile trolley 21 to move along the X-axis;

[0079] The mobile trolley frame 23 is slidably disposed in the frame 11, and the second translation mechanism 25 is used to drive the mobile trolley frame 23 to move along the Y-axis; and the X-axis is perpendicular to the Y-axis.

[0080] By slidably mounting the mobile trolley 21 within the mobile trolley frame 23 and translating it under the drive of the first translation mechanism 24, the lateral span of the entire gantry crane can be adjusted. The movement of the mobile trolley frame 23 within the frame 11 enables the translation of the suspended object.

[0081] The folding gantry lifting device provided in this application has a lifting device 2 that moves in the plane formed by the X-axis and Y-axis, which is achieved by a moving trolley 21, a lifting mechanism 22, a moving trolley frame 23, a first translation mechanism 24, and a second translation mechanism 25.

[0082] Specifically, the mobile trolley 21 moves within the mobile trolley frame 23, with the power for movement provided by the first translation mechanism 24; the mobile trolley frame 23, together with the mobile trolley 21, can move within the frame 11, with the power for movement provided by the second translation mechanism 25. By setting the direction of movement of the mobile trolley 21 perpendicular to the direction of movement of the mobile trolley frame 23, the mobile trolley 21 can move in a plane, thereby enabling the lifting mechanism 22 located on the mobile trolley 21 to move in a plane and perform lifting operations at various positions.

[0083] Preferably, the mobile trolley frame 23 is provided with rollers 231 at both ends, and the frame 11 is provided with matching track grooves 113; and / or,

[0084] The mobile trolley 21 is equipped with wheels, which roll on the mobile trolley frame 23.

[0085] The movement of the preferred mobile trolley frame 23 is achieved through the cooperation of rollers 231 and track grooves 113. Specifically, rollers 231 are provided at both ends of the mobile trolley frame 23, and matching track grooves 113 are provided on the frame 11. The rollers 231 are embedded in the track grooves 113, which can roll flexibly and prevent them from falling off.

[0086] The movement of the mobile trolley 21 within the mobile trolley frame 23 can be achieved by setting wheels that cooperate with the mobile trolley frame 23.

[0087] Both the first translation mechanism 24 and the second translation mechanism 25 can use hydraulic cylinders, which can be extended and retracted to achieve movement.

[0088] Preferably, the frame 11 is provided with 4 folding beams 112, two folding beams 112 form a group, and each group is provided with 1-2 lifting devices 2, and the track groove 113 is provided on the folding beams 112.

[0089] More preferably, the frame 11 is provided with four folding beams 112, with two folding beams 112 forming a group. Each group is provided with one or two lifting devices 2, and the track groove 113 is provided on the folding beams 112. Thus, the folding gantry crane provided in this application is provided with two or four lifting devices 2, which can be used separately or in combination, solving the problem of conventional gantry cranes having single operation and frequent swaying when lifting long objects, and is more flexible.

[0090] Preferably, there are two frame flipping mechanisms 12, which are located on the two folding beams 112 in the middle.

[0091] The preferred frame tilting mechanism 12 has two parts, one on each of the two middle folding beams 112. The two outer folding beams 112 are fixedly connected at both ends to the two ends of the two fixed beams 111, forming a rectangular shape. The four folding beams 112 can support multiple lifting devices 2 for operation and also realize a multi-point gantry structure with a large longitudinal span. The lifting operation is more stable than that of conventional gantry cranes, which can effectively prevent uneven loading and avoid tipping.

[0092] Preferably, the lifting mechanism 22 includes a wire rope 221, a fixed pulley 222, a movable pulley 223, and a lifting power mechanism 224. The movable pulley 223 is located at the power output end of the lifting power mechanism 224 and is close to or far from the fixed pulley 222.

[0093] The wire rope 221 is wound around the outer periphery of the fixed pulley 222 and the movable pulley 223, and the wire rope 221 is equipped with a lifting device to lift or lower objects as the movable pulley 223 moves.

[0094] The preferred lifting mechanism 22 includes a wire rope 221, a fixed pulley 222, a movable pulley 223, and a lifting power mechanism 224. By extending or retracting the lifting power mechanism 224, the distance between the movable pulley 223 and the fixed pulley 222 is increased or decreased, thereby pulling or releasing the wire rope 221, causing the hanging part of the wire rope 221 (i.e. the part equipped with the lifting device) to move up or down, thus lifting or lowering the object.

[0095] The lifting power mechanism 224 can be a hydraulic cylinder, with a fixed pulley 222 located at one end of the cylinder and a movable pulley 223 located at one end of the piston rod. The lifting power can also be transmitted using a lead screw or other methods.

[0096] Preferably, the lifting device and the wire rope 221 are detachably connected.

[0097] If the preferred lifting tool and wire rope 221 are detachably connected, different special lifting tools can be replaced according to different working conditions.

[0098] The folding gantry crane device provided in this application, when transferred using a transport vehicle, follows these steps:

[0099] 1) The transport vehicle moves to a position below the folding gantry crane and below the first support beam 1121, using the transport vehicle to support the plane formed by the multiple first support beams 1121. For example... Figure 13 As shown.

[0100] 2) Then, activate the outrigger extension mechanism 133 on one side of the second support beam 1122 to retract the outrigger on that side; if the outrigger 13 is retractable, activate the outrigger extension mechanism 133 before or simultaneously with retracting the outrigger to shorten it. Afterwards, activate the frame flipping mechanism 12, causing multiple second support beams connected to the fixed beams on that side to rotate around hinge point B, folding this part above the first support beam 1121. For example... Figure 14 As shown.

[0101] 3) At this point, the side legs of the first beam gradually retract, as... Figure 15 As shown.

[0102] 4) Activate the outrigger extension mechanism 133 on one side of the first support beam 1121 to retract the outrigger 13 closest to the first support beam 1121. If the outrigger 13 is retractable, activate the outrigger extension mechanism 133 before or simultaneously with retracting the outrigger to shorten it. At this point, the entire folding gantry crane is folded up and positioned on the transport vehicle, forming a transport configuration. Figure 16 As shown; another angle view is as follows Figure 17 As shown.

[0103] Upon arrival at the destination, the folding gantry crane provided in this application can be unloaded by itself and unfolded into an operational state.

[0104] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
