A gantry with a reinforcing structure

Abstract

This utility model discloses a hoisting gantry with a reinforced structure, comprising two symmetrical inverted U-shaped frames and two fixedly installed moving tracks on the ground. A moving platform is installed above the two inverted U-shaped frames, and a movable hoisting device is installed on the moving platform. Mounting seats are installed at both ends of each inverted U-shaped frame, and long shells are fixedly connected to both sides of the bottom of each mounting seat. Two pulleys that roll on the moving tracks are rotatably connected to the inner cavity of each long shell. When the hoisting device is used for hoisting operations, the inverted U-shaped frames are in a stopped state. At this time, the U-shaped plates extend, causing the trapezoidal pressure blocks to contact the ground, thus restricting the movement of the inverted U-shaped frames and effectively ensuring their stability during hoisting. This achieves the goal of limiting the gantry frame through friction, preventing displacement during hoisting, and improving hoisting stability.

Description

Technical Field

[0001] This utility model belongs to the field of gantry crane technology, and in particular relates to a hoisting gantry crane with a reinforcement structure. Background Technology

[0002] A hoisting gantry mainly consists of a gantry frame, a hoist, a crossbeam, a traveling mechanism, and a control system. The gantry frame is typically constructed from welded or bolted steel sections, providing stable support for the entire system. The hoist is responsible for lifting heavy objects; electric hoists are driven by an electric motor and utilize wire ropes and pulley systems for lifting and lowering. The crossbeam supports the hoist and provides a track for its horizontal movement. The traveling mechanism can be either rail-mounted or trackless. Rail-mounted gantry frames move by laying tracks on the ground, while trackless gantry frames move using tires or tracks.

[0003] Typically, at the beginning of lifting a heavy object—that is, during the process of lifting the object from the ground and detaching it from the support surface—the gantry crane needs to remain stationary. This is because it is crucial to ensure a smooth lifting process and that the lifting devices, such as ropes, are evenly stressed. This prevents instability caused by movement of the gantry crane, such as swaying or tilting, which could affect lifting safety and subsequent operations. To improve the stability of the gantry crane when stationary, we have designed a lifting gantry crane with a reinforced structure. When the gantry crane is stationary, friction is used to limit its position, preventing displacement during lifting and improving lifting stability. Utility Model Content

[0004] The purpose of this utility model is to provide a lifting gantry with a reinforced structure, which limits the position of the gantry by friction, prevents displacement during lifting, and improves the stability of lifting, thereby solving the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A hoisting gantry with a reinforced structure includes two symmetrical inverted U-shaped frames and two moving tracks fixedly installed on the ground. A moving platform is installed above the two inverted U-shaped frames. A movable hoisting device is set on the moving platform. Mounting seats are installed at both ends of the inverted U-shaped frames. Long shells are fixedly connected to both sides of the bottom of the mounting seats. Two pulleys that roll on the moving tracks are rotatably connected to the inner cavity of the long shells. Two symmetrical fixed seats are fixedly connected to the surface of the mounting seats. A U-shaped plate is fixedly connected to the top of the two fixed seats. A cylinder is fixedly installed on the top of the U-shaped plate. The output end of the cylinder extends through to the bottom of the U-shaped plate and is fixedly installed with a trapezoidal pressure block.

[0006] Preferably, a slide rail is fixedly connected to one side of the fixed base, and two sliding sleeves are slidably connected to the surface of the slide rail. One side of the two sliding sleeves is fixedly connected to the trapezoidal pressure block.

[0007] Preferably, guide rods are fixedly connected to both sides of the top of the trapezoidal pressure block, and the top of the guide rods extends through to the top of the U-shaped plate and is slidably connected to the U-shaped plate.

[0008] Preferably, the bottom of the trapezoidal pressure block is provided with multiple stripes.

[0009] Preferably, both ends of the inverted U-shaped frame are fixedly connected to connecting seats, and the mounting seats are fixedly installed in the inner cavity of the connecting seats.

[0010] The beneficial effects of this utility model are: 1. When the inverted U-shaped frame is hoisted by the hoisting equipment, it is in a stopped state. At this time, the U-shaped plate is extended, so that the trapezoidal pressure block contacts the ground, which can restrict the movement of the inverted U-shaped frame and effectively ensure the stability of the inverted U-shaped frame during the hoisting process. This can achieve the goal of limiting the gantry frame through friction, avoiding displacement during the hoisting process, and improving the stability of the hoisting. 2. This utility model uses the cooperation of slide rail, slide sleeve and guide rod. During the movement of the trapezoidal pressure block, the slide sleeve will slide on the surface of the slide rail, which will stabilize the movement and use of the trapezoidal pressure block. During the movement of the trapezoidal pressure block, the guide rod will also slide on the U-shaped plate, which will also increase the stability of the trapezoidal pressure block in use. 3. By designing the stripes, this utility model increases the friction between the trapezoidal block and the ground, ensuring the stability of the trapezoidal block. Attached Figure Description

Detailed Implementation

[0013] In the following description, embodiments of the hoisting gantry with a reinforced structure of the present invention will be described with reference to the accompanying drawings.

[0014] Figure 1-4 This invention illustrates a hoisting gantry with a reinforced structure according to an embodiment of the present invention. It includes two symmetrical inverted U-shaped frames 1 and two fixedly mounted moving tracks 8. A moving platform 2 is mounted above the two inverted U-shaped frames 1, and a movable hoisting device 3 is mounted on the moving platform 2. Mounting seats 5 are mounted at both ends of each inverted U-shaped frame 1, and connecting seats 4 are fixedly connected to both ends of each inverted U-shaped frame 1. The mounting seats 5 are fixedly installed in the inner cavity of the connecting seats 4. Long shells 6 are fixedly connected to both sides of the bottom of the mounting seats 5. Two pulleys 7 that roll on the moving tracks 8 are rotatably connected to the inner cavity of the long shells 6. Two symmetrical fixing seats 9 are fixedly connected to the surface of the mounting seats 5. A U-shaped plate 10 is fixedly connected to the top of the two fixing seats 9. A cylinder 11 is fixedly mounted on the top of the U-shaped plate 10. The output end of the cylinder 11 extends through to the bottom of the U-shaped plate 10 and is fixedly mounted with a trapezoidal pressure block 12. A slide rail 13 is fixedly connected to one side, and two sliding sleeves 14 are slidably connected to the surface of the slide rail 13. One side of the two sliding sleeves 14 is fixedly connected to the trapezoidal pressure block 12. Guide rods 15 are fixedly connected to both sides of the top of the trapezoidal pressure block 12. The top of the guide rods 15 extends through to the top of the U-shaped plate 10 and is slidably connected to the U-shaped plate 10. Through the cooperation of the slide rail 13, sliding sleeves 14 and guide rods 15, the trapezoidal pressure block 12 will drive the sliding sleeves 14 to slide on the surface of the slide rail 13 during movement, which will stabilize the movement and use of the trapezoidal pressure block 12. The trapezoidal pressure block 12 will also drive the guide rods 15 to slide on the U-shaped plate 10 during movement, which will also increase the stability of the trapezoidal pressure block 12 during use. The bottom of the trapezoidal pressure block 12 is provided with multiple stripes 16. The stripes 16 increase the friction between the trapezoidal pressure block 12 and the ground, ensuring the stability of the trapezoidal pressure block 12.

[0015] Working principle: When this utility model is used, the inverted U-shaped frame 1 is in a stopped state when the hoisting equipment 3 is used for hoisting. At this time, the U-shaped plate 10 extends, so that the trapezoidal pressure block 12 contacts the ground, which can restrict the movement of the inverted U-shaped frame 1 and effectively ensure the stability of the inverted U-shaped frame 1 during the hoisting process. After the hoisted item is lifted, the U-shaped plate 10 shortens, so that the trapezoidal pressure block 12 leaves the ground. Then, the pulley 7 at the bottom of the inverted U-shaped frame 1 moves on the moving track 8 to realize the hoisting movement. When the item is placed, the trapezoidal pressure block 12 contacts the ground to ensure hoisting stability.

[0016] In summary, when the gantry crane with reinforced structure is hoisted by the hoisting equipment 3, the inverted U-shaped frame 1 is in a stopped state. At this time, the U-shaped plate 10 extends, causing the trapezoidal pressure block 12 to contact the ground, which can restrict the movement of the inverted U-shaped frame 1 and effectively ensure the stability of the inverted U-shaped frame 1 during the hoisting process. This achieves the goal of limiting the gantry crane through friction, avoiding displacement during the hoisting process, and improving the stability of the hoisting.
