Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, and in particular to a lifting and stabilizing device for materials with large depth. Background Technology

[0002] Mobile gantry cranes are a common type of lifting equipment, mainly used for lifting and moving large and heavy items. When in operation, gantry cranes often struggle to stably handle large, especially long or narrow, materials. For example, with excessively long materials, the distance between the lifting hooks may be too close, causing the material to become unbalanced at both ends during lifting, potentially leading to the material detaching from the hooks. Similarly, for narrow materials, the gantry crane's lifting mechanism may not be well-suited, resulting in the material not being properly clamped and unstable lifting. Utility Model Content

[0003] The purpose of this invention is to provide a lifting and stabilizing device for materials with large depth, so as to solve the problem that existing gantry cranes cannot stably lift some materials with large depth.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A lifting and stabilizing device for deep-penetrating materials includes a mobile chassis, a variable-span gantry frame, and lifting mechanisms. The variable-span gantry frame is mounted on the mobile chassis, and the lifting mechanisms are symmetrically arranged and respectively installed on the non-variable-span sides of the variable-span gantry frame.

[0006] The lifting mechanism includes a rope reel, steel rope, cross plates, and hooks. The three rope reels are all installed on the non-variable span side of the variable span gantry frame. The three steel ropes respectively connect the two cross plates and the rotating connection points of the two cross plates to the working ends of the three rope reels. The two hooks are respectively set on the outer ends of the two cross plates.

[0007] A further technical solution is as follows: The variable span gantry includes columns, fixed beams, telescopic beams, a motor, and a screw. The four columns are distributed at four corners and slidably installed on the mobile chassis in the same direction. The two fixed beams and two telescopic beams are arranged alternately in quadrilaterals and are respectively connected to the four columns. The motor is installed on the mobile chassis. The screw is rotatably installed on the mobile chassis and is arranged parallel to the telescopic beams. One end of the screw is connected to the motor. The screw is threadedly connected to the column. The mobile chassis is provided with a stopper adapted to the column.

[0008] A further technical solution is that the stopper is a push rod motor, and the telescopic end of the push rod motor is adapted to the column.

[0009] A further technical solution is that the telescopic beam consists of an outer beam and an inner beam that is slidably connected to the outer beam.

[0010] A further technical solution is that the outer beam is provided with an electric latch that is compatible with the inner beam.

[0011] A further technical solution is that the rope reel is an electric hoist.

[0012] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0013] This invention proposes a lifting and stabilizing device for materials with large depth. This device is highly effective for lifting large and narrow materials, ensuring lifting stability in two ways: First, the variable-span gantry frame extends the distance between lifting mechanisms, preventing imbalance at both ends when lifting longer and larger materials. Second, the horizontal plates of the lifting mechanisms can be angled to ensure that the hooks can clamp even narrow materials. This device prevents materials from slipping off the hooks during clamping, ensuring a stable and reliable lifting process. Attached Figure Description

[0023] This implementation example Figure 1 and Figure 2 As shown, a lifting and stabilizing device for materials with large depth includes a mobile chassis 1, a variable-span gantry frame 2, and a lifting mechanism 3. The variable-span gantry frame 2 is mounted on the mobile chassis 1, and the lifting mechanism 3 is symmetrically arranged and installed on the non-variable-span sides of the variable-span gantry frame 2.

[0024] The lifting mechanism 3 includes a rope winder 4, a steel rope 5, a cross plate 6, and a hook 7. The three rope winders 4 are all installed on the non-variable span side of the variable span gantry 2. The three steel ropes 5 respectively connect the two cross plates 6 and the rotating connection points of the two cross plates 6 to the working ends of the three rope winders 4 one by one. The two hooks 7 are respectively set on the outer ends of the two cross plates 6.

[0025] Before lifting materials, adjust the span of the variable-span gantry 2 and the clamping point distance of the lifting mechanism 3 according to the specifications of the materials to be lifted, such as length and width, to prevent imbalance at both ends of the material or loose clamping during lifting, and ensure the stability of the material lifting. Specifically, for longer materials, to ensure sufficient distance between the lifting point of the device and the center of gravity of the material, the span of the variable-span gantry 2 can be increased; for narrower materials, a rope reel 4 can be controlled to lift the rotating connection of the two horizontal plates 6 upwards through the steel rope 5, so that the two horizontal plates 6 will move closer to each other, that is, the two hooks 7 will also move closer to each other, thus clamping or adapting to the narrower material. This device can achieve stable lifting and movement of some longer or narrower materials, or both. Example

[0026] Based on the above embodiments, this embodiment shows that the variable span gantry 2 includes columns 8, fixed beams 9, telescopic beams 10, a motor 11, and a screw 12. The four columns 8 are distributed at four corners and slidably mounted on a movable chassis 1 in the same direction. The two fixed beams 9 and two telescopic beams 10 are arranged alternately in a quadrilateral shape and connected to the four columns 8 respectively. The motor 11 is mounted on the movable chassis 1. The screw 12 is rotatably mounted on the movable chassis 1 and arranged parallel to the telescopic beams 10. One end of the screw 12 is connected to the motor 11, and the screw 12 is threadedly connected to the columns 8. A stopper 13 adapted to the columns 8 is provided on the movable chassis 1. The stopper 13 is a push rod motor, and the telescopic end of the push rod motor is adapted to the columns 8.

[0027] Four upright columns 8 are vertically distributed at the four corners and their bottoms are slidably mounted on the mobile chassis 1. The adjacent sides of the four upright columns 8 are connected by fixed beams 9 and telescopic beams 10, respectively. Then, the motor 11 drives the screw 12 to rotate, and the screw 12 moves the upright columns 8 along the telescopic direction of the telescopic beams 10 to achieve changes in span. When the span of the variable-span gantry 2 changes, the stopper 13 will remain stationary against one side of the upright column 8, while the upright column 8 on the other side can move.

[0028] Preferably, the telescopic beam 10 consists of an outer beam 14 and an inner beam 15 that is slidably connected to the outer beam 14.

[0029] The outer beam 14 and the inner beam 15 are slidably connected, which serves to connect the column 8 and guide the movement of the column 8.

[0030] Preferably, the outer beam 14 is provided with an electric latch 16 that is compatible with the inner beam 15.

[0031] The electric latch 16 is used to lock the position between the outer beam 14 and the inner beam 15.

[0032] Preferably, the rope winder 4 is an electric hoist.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
