Description

Technical Field

[0001] The utility model relates to the technical field of straddle carriers, and more specifically to a three-support point container straddle carrier. Background Art

[0002] Straddle carriers, also known as container straddle carriers, energy storage cabinet straddle carriers or bridge cranes, are responsible for lifting, moving and unloading containers and transporting them to their destinations.

[0003] The straddle carriers in the prior art are generally controlled and moved by four wheels. When the straddle carrier needs to turn on the spot, the required turning radius is large, the steering flexibility is poor, and a large turning space is required, which is inconvenient to operate. In addition, the existing straddle carriers all use the winding of wire ropes to achieve the lifting of containers. However, during the transportation and transfer process, when the straddle carrier is performing braking, deceleration, steering and rotation, the wire ropes are very likely to swing in the air with the lifted containers, which not only affects the operation of the straddle carrier, but also causes great wear between the wire ropes and the equipment, and even causes the wire ropes to break and the containers to fall, posing a great safety hazard.

[0004] Based on the above background, a three-pivot container straddle carrier is proposed to solve the problem. Summary of the invention

[0005] Other features and advantages of the utility model will be described in the following description, and partly become apparent from the description, or understood by implementing the utility model. The purpose and other advantages of the utility model can be realized and obtained through the structures specifically pointed out in the description and other drawings of the description.

[0006] The utility model aims to overcome the above-mentioned shortcomings and provide a three-support point container straddle carrier.

[0007] To achieve the above-mentioned purpose, the technical solution of the utility model is: a three-point container straddle carrier, comprising: an electric hoist assembly, a wire rope, a lifting support frame, a moving wheel, a connecting frame, and a clamping and anti-sway component. Three lifting support frames are installed on both sides of the electric hoist assembly, two of the three lifting support frames are on the same side of the electric hoist assembly, and the other is located on the other side of the electric hoist assembly. Moving wheels are arranged on the lower sides of the three lifting support frames, and a wire rope is passed through and wound on the electric hoist assembly. Two connecting frames are respectively installed on both sides of the electric hoist assembly, and the clamping and anti-sway components are installed on the connecting frames and the clamping and anti-sway components are located on the sides of the four corners of the container; wherein the clamping and anti-sway component comprises a telescopic arm, a linear module, a motor, and a clamping arm. The telescopic arm is installed on the connecting frame and the other side is connected to the linear module. The motor is arranged on the linear module, and the clamping arm is installed on the linear module and located on the sides of the corners of the container.

[0008] Preferably, a cab is arranged between two lifting support frames located on the same side.

[0009] Preferably, the steel wire rope is detachably connected to the upper part of the container.

[0010] Preferably, the three lifting support frames stand on the electric hoist assembly in the form of an isosceles triangle.

[0011] Preferably, the linear module includes a housing, a slide rail, a screw rod, a nut block, and a connecting plate. The slide rail is installed on the side of the housing, the screw rod is inserted into the housing, the screw rod is threadedly connected to the nut block, the nut block is connected to the connecting plate, and both sides of the connecting plate are installed on the slide rail.

[0012] Preferably, the motor is mounted on the housing and is transmission-connected to the screw rod, and the housing is connected to the telescopic arm.

[0013] Preferably, the clamping arm is connected to the connecting plate.

[0014] Preferably, the clamp arm is divided into a V-shaped plate and a bottom support plate, the bottom support plate is installed on the lower side of the V-shaped plate, and the V-shaped plate is connected to the linear module.

[0015] The beneficial effects of the utility model are as follows: the utility model controls the linear module with the clamp arm to lift and adjust to the corresponding corner position of the container through a motor, and the telescopic arm then pushes the linear module with the clamp arm forward until the clamp arm is tightly clamped on the corner of the container, and the four corners are tightly clamped, which has the effect of fixing the container, making the straddle carrier more stable during driving, not prone to shaking due to wire rope suspension, and has higher safety. In addition, three lifting support frames form a three-point support on the electric hoist assembly, so that the turning radius required for the straddle carrier during the original turning is smaller, thereby improving the steering flexibility, especially for the straddle carrier that can provide a smaller channel width when performing tunnel operations, and the three-point straddle carrier can also adapt to work in a narrow space.

[0025] According to some embodiments of the present application, optionally, a cab 7 is provided between two lifting support frames 3 on the same side, which has the function of controlling the circuit equipment such as the travel, start and stop of the straddle carrier.

[0026] According to some embodiments of the present application, the steel wire rope 2 is optionally detachably connected to the upper part of the container, so as to realize the function of the steel wire rope 2 to lift, transport and unload the container.

[0027] According to some embodiments of the present application, optionally, three lifting support frames 3 stand in an isosceles triangle on the electric hoist assembly 1.
