[0002] A crane refers to a multi-action hoisting machine that vertically lifts and horizontally transports heavy objects within a certain range. It is also called an overhead crane, a gantry crane, or a hoist. A gantry crane is a deformation of a bridge crane, also known as a gantry crane. It is mainly used for outdoor cargo yards, material yards, and the loading and unloading of bulk goods. Gantry cranes have the characteristics of high site utilization rate, large operating range, wide adaptability, and strong versatility, and are widely used in port cargo yards. Its metal structure is like a gantry frame. Two support legs are installed under the load-bearing main beam, which can directly run on the ground track. The two ends of the main beam can have outstretched cantilever beams. A transverse movement mechanism is installed at the top of the gantry crane for loading and unloading goods.

[0025] The following further illustrates the present utility model with reference to the drawings and embodiments:

[0026] Such as Figures 1 to 3As shown in the figure, a transverse trolley for a single beam includes a traveling mechanism 100 movably arranged on the single beam, a hoisting mechanism 200 for vertically lifting materials, a control mechanism 300 for controlling the operation of the traveling mechanism 100 and the hoisting mechanism 200, and a protection mechanism 400 for protecting the cables of the traveling mechanism 100, the hoisting mechanism 200, and the control mechanism 300. The hoisting mechanism 200 is arranged at the bottom of the traveling mechanism 100, the control mechanism 300 is arranged on the hoisting mechanism 200, and the protection mechanism 400 is arranged above the traveling mechanism 100. The traveling mechanism 100 includes two groups of support components 110 arranged on the surface of the single beam. The two groups of support components 110 are arranged along the length direction of the single beam, and two support components 110 are symmetrically arranged about the width direction of the single beam in each group. Traveling wheels 120 in contact with the wing plates of the single beam are respectively arranged on each group of support components 110. A driving motor 130 for driving the corresponding traveling wheels 120 to rotate is arranged on one of the two groups of support components 110. An auxiliary component 140 in contact with the bottom of the single beam is respectively arranged on each group of support components 110.

[0027] Among them, the support component 110 includes a support plate 111. Limiting grooves 112 adapted to the wing plates of the single beam are respectively opened on both sides of the support plate 111. The traveling wheels 120 are movably arranged on the support plate 111. One driving motor 130 is respectively installed on the opposite sides of the two support plates 111 in one of the two groups. The output shaft of the driving motor 130 is in transmission connection with the corresponding traveling wheel 120. One auxiliary component 140 is respectively arranged between the two support plates 111 in each group. The support plate 111 can provide a support basis for the traveling wheels 120, the driving motor 130, and the auxiliary component 140. By placing the wing plate of the single beam in the inner cavity of the limiting groove 112, the support plate 111 can be limited, the support plate 111 can be kept from tilting, and a good balance state can be maintained, which helps to improve the moving stability of the traveling mechanism 100.

[0028] Among them, a group of traveling wheels 120 are respectively rotatably connected to the opposite sides of the two support plates 111 in each group, and two traveling wheels 120 in each group are arranged along the length direction of the support plate 111.

[0029] Among them, the auxiliary component 140 includes a shaft rod 141 rotatably connected between the two support plates 111 in each group.

When the traveling mechanism 100 moves, the auxiliary component 140 can be driven to rotate at the bottom of the single beam, the friction between the top of the hoisting mechanism 200 and the single beam can be reduced, and the moving flexibility of the traveling mechanism 100 can be further improved.

[0030] Among them, a pallet 150 is movably clamped between two shaft rods 141. The pallet 150 is located between two support plates 111 in each group. The pallet 150 can play an auxiliary supporting role for the shaft rods 141, and further improve the rotational stability of the shaft rods 141.

[0031] Among them, the hoisting mechanism 200 includes a winch 210 located below the single beam. Both the support plates 111 and the pallet 150 are fixedly connected to the top of the winch 210. A hook assembly 220 is suspended below the winch 210 by a steel wire rope. By starting the winch 210, the steel wire rope can be wound or released, so as to lift or lower the hook assembly 220.

[0032] Among them, the hook assembly 220 includes a T-shaped rod 221. Guide wheels 222 are installed at both ends of the T-shaped rod 221, and a hook 223 is installed at the bottom end of the T-shaped rod 221. The hook assembly 220 can hoist materials, facilitating subsequent material handling operations.

[0033] Among them, the control mechanism 300 includes a mounting plate 310 fixedly connected to one side of the winch 210 and having a U-shaped structure.

The electric control system 320 can adjust the working states or parameters of the drive motor 130 and the electric control system 320 to achieve the effect of automatic operation. The electric control system 320 can be composed of a PLC control box and a controller installed inside the control box.

[0034] Among them, the protection mechanism 400 includes a supporting component 410 provided on one side of the single beam. A drag chain 420 is provided on the supporting component 410. The cables of the drive motor 130, the winch 210, and the electric control system 320 all pass through the drag chain 420 and are electrically connected to an external power supply. The supporting component 410 can provide a supporting basis for the drag chain 420. The drag chain 420 can play a role in towing and protecting the cables of the drive motor 130, the winch 210, and the electric control system 320, effectively preventing interference and entanglement between the cables, ensuring the operation stability and reliability of the cross-travel trolley, and also effectively preventing the cables from being broken, worn, or short-circuited due to external forces, which helps to extend the service life of the cables.

[0035] Among them, the supporting component 410 includes two baffles 411 installed on one side of the single beam. The drag chain 420 is located between the two baffles 411. One end of the drag chain 420 is fixedly connected to the inner wall surface of the baffle 411, and the other end of the drag chain 420 is fixedly connected to one of the support plates 111. A number of equally spaced brackets 412 are fixedly connected to the bottom of the two baffles 411. One end of the bracket 412 is fixedly connected to the single beam. The supporting component 410 can provide a supporting basis and an installation space for the drag chain 420.

[0036] The working principle of the present utility model is as follows: By starting the winch 210 to perform the operation of releasing the steel wire rope, the hook assembly 220 is lowered to the required position, the material is suspended on the hook 223, and then the winch 210 is started again to perform the operation of winding the steel wire rope, and the material can be lifted to the required position; By starting the drive motor 130, the output end of the drive motor 130 can drive the traveling wheels 120 to roll on the cross beam to achieve the transverse movement operation, and the traveling mechanism 100 drives the hoisting mechanism 200, the control mechanism 300 and the material to move along the cross beam synchronously until the required position, so as to realize the handling operation of the material.

[0037] The present utility model has been described exemplarily above in conjunction with the accompanying drawings. Obviously, the specific implementation of the present utility model is not limited by the above-mentioned manner. As long as various improvements are made by adopting the method concept and technical solution of the present utility model, or directly applied to other occasions without improvement, they are all within the protection scope of the present utility model.
