Description

Technical Field

[0001] This utility model relates to the field of crane technology, specifically to a trolley running device for a single-girder crane. Background Technology

[0002] A crane mainly consists of a hoisting mechanism, traveling mechanism, luffing mechanism, slewing mechanism, and metal structure. The hoisting mechanism is the basic working mechanism of a crane, mostly composed of a hoisting system and a winch, though some use a hydraulic system to lift and lower heavy objects. The traveling mechanism is used to move heavy objects horizontally or adjust the crane's working position, generally consisting of a motor, reducer, brake, and wheels. The luffing mechanism is only equipped on boom-type cranes; the boom's amplitude decreases when raised and increases when lowered, and it is divided into balanced and unbalanced luffing mechanisms. The slewing mechanism is used to rotate the boom and consists of a drive unit and a slewing bearing. The metal structure is the crane's skeleton; main load-bearing components such as the bridge frame, boom, and gantry can be box-shaped, truss, or web-plate structures. Some use structural steel as support beams. Single-girder cranes usually refer to single-girder bridge cranes; the main beams of single-girder crane bridge frames often use I-beams or a combination of steel profiles and plates. Crane trolleys are typically assembled using hand-operated hoists, electric hoists, or hoists as lifting mechanism components, and offer both ground and overhead operation options. Ground operation includes both wired handle operation and remote control handle operation; overhead operation refers to cab operation. Cabs are available in open and closed types, and can be installed on the left or right side depending on the specific needs. Entry directions include side and end views, allowing users to choose according to various requirements.

[0003] The existing single-girder crane trolley traveling device has poor stability in the movement of the crane trolley, which affects work efficiency. In addition, the existing single-girder crane trolley traveling device is not convenient for cleaning dust and debris in the track groove, which affects the movement of the crane trolley. The present invention solves the above problems by providing a single-girder crane trolley traveling device. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example 1

[0022] Please see Figures 1 to 5 This utility model provides a technical solution: a single-girder crane trolley running device, including a crossbeam 1 and a crane trolley 2. The crossbeam 1 has rectangular grooves on both its front and rear sides, with the front-to-back direction as the depth direction and the left-to-right direction as the length direction. The ends of rectangular sliders 10 are located inside the rectangular grooves, and the rectangular sliders 10 can slide along the length direction of the rectangular grooves. A dual-axis motor 3 is installed inside the crane trolley 2. First round rods 4 are installed at both ends of the dual-axis motor 3. A first transmission wheel 5 with the same center as the first round rod 4 is installed on the outer surface of the first round rod 4. The first transmission wheel 5 is connected to a second transmission wheel 5 via a transmission chain. The first round rod 4 is rotatably connected to the inner wall of the trolley 2 via a bearing. The second round rod 6 is rotatably connected to the inside of the trolley 2 via a bearing. The second round rod 6 and the roller 8 are at the same center. The highest position of the trolley 2 is higher than the position of the crossbeam 1. The second transmission wheel 7 is rotatably connected to the outer surface of the second round rod 6. The roller 8 is installed at the end of the second round rod 6. The position of the roller 8 is located inside the track groove. The cleaning brush 21 and the scraper 23 are both in contact with the track groove. Fixed rods 9 are installed at the front and rear of the trolley 2. A rectangular slider 10 is installed at the end of the fixed rod 9 away from the trolley 2.

[0023] In use, when the trolley 2 moves, the dual-axis motor 3 drives the first round rod 4 and the first transmission wheel 5 to rotate. The first transmission wheel 5 is connected to the second transmission wheel 7 through a transmission chain, which in turn drives the second round rod 6 and the roller 8 to rotate. This causes the roller 8 to move inside the track groove. The end of the rectangular slider 10 is located inside the rectangular slide groove. The rectangular slider 10 moves with the trolley 2, moving along the length of the rectangular slide groove. This serves as a positioning and guiding function, improving the stability of the trolley 2 and enhancing its practicality. Example 2

[0024] Please see Figures 1 to 4This utility model provides a technical solution: a single-girder crane trolley running device, wherein a support block 11 and a mating block 12 are installed on the top of the crane trolley 2, the height of the support block 11 being higher than the height of the mating block 12; a dual-shaft motor 3, an electric push rod 13, and a drive motor 20 are all electrically connected to an external power source via wires; electric push rods 13 are installed on both sides of the support block 11, and an adjusting block 14 is installed on the movable end of the electric push rod 13; positioning sliders 15 are installed on the front and rear of the adjusting block 14; an L-shaped rod 16 is rotatably connected to one side of the mating block 12 via a shaft, and a [missing information - likely a component or component] is installed on one side of the L-shaped rod 16. A horizontal plate 17 has a connecting rod 18 mounted on its top. The front of the connecting rod 18 has a positioning groove with the depth direction in the front-back direction and the length direction in the up-down direction. The end of the positioning slider 15 is located inside the positioning groove and can slide along the length direction of the positioning groove. A mating plate 19 is mounted on the end of the L-shaped rod 16. A drive motor 20 is mounted on the top of the mating plate 19. A cleaning brush 21 is mounted on the output end of the drive motor 20. A support rod 22 is mounted on the inner wall of the L-shaped rod 16. A scraper 23 is mounted on the end of the support rod 22 away from the L-shaped rod 16. A track groove is opened on the top of the crossbeam 1.

[0025] In use, the cleaning brush 21 and scraper 23 move with the crane trolley 2, and both the cleaning brush 21 and scraper 23 are located inside the track groove. The drive motor 20 drives the cleaning brush 21 to rotate, so that the cleaning brush 21 washes the dust and debris in the track groove. The scraper 23 pushes the dust and debris to move, so as not to affect the movement of the crane trolley 2. When the crane trolley 2 moves to the left, the cleaning brush 21 and scraper 23 on the left side are in contact with the track groove, and the cleaning brush 21 and scraper 23 on the right side are raised. The electric push rod 13 drives the adjusting block 14 and the positioning slider 15 to move. The end of block 15 is located inside the positioning groove. The movement of positioning slider 15 drives the connecting rod 18 to move. The L-shaped rod 16 rotates at the connection point with the mating block 12, causing the L-shaped rod 16 to drive the cleaning brush 21 and scraper 23 to tilt upwards, so that the cleaning brush 21 and scraper 23 move away from the track groove. Conversely, when the crane trolley 2 moves to the right, the cleaning brush 21 and scraper 23 on the right side descend and abut against the track groove, while the cleaning brush 21 and scraper 23 on the left side rise, which facilitates the cleaning of dust and debris in the track groove as the crane trolley 2 moves, avoids affecting the movement of the crane trolley 2, and improves practicality.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
