Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 2 to 8, the lengthening device for a crane according to the present invention includes a moving frame 100, a lengthening mechanism 200, a buffer 400, and a scraper 300.

Both ends of removing frame 100 all are equipped with extension mechanism 200, all be equipped with electrically conductive frame 500 on every extension mechanism 200, when the installation, people need to install extension mechanism 200 on the position that removes frame 100 and correspond, and install electrically conductive frame 500 on the position that extension mechanism 200 corresponds, afterwards, people alright connect the supply cable 600 who is used for the hoist and twine on a plurality of electrically conductive frames 500, when people remove electrically conductive frame 500, alright extension supply cable's length, and this kind of design is often used for hoist running length to exceed more than 70 meters, need the workshop of very long cable, that is, satisfy people's production demand.

Each lengthening mechanism 200 comprises a shell 210, at least two vertical plates 220 and at least two reinforcing plates 230 are arranged in the shell 210, each reinforcing plate 230 is perpendicular to the vertical plate 220, and the firmness of the shell 210 is effectively enhanced through the arrangement of the vertical plates 220 and the reinforcing plates 230, so that the lengthening mechanism 200 is not easy to damage in the using process.

When the roller 110 rotates, and when the moving frame 100 moves, the roller 110 will move along the predetermined orbit of the crane, and in the utility model, the scraper 300 can be detachably connected to each lengthening mechanism 200, the bottom of the moving frame 100 is provided with at least one pair of rollers 110, and the lowest position of the roller 110 and the bottom end of the scraper 300 are located on the same horizontal plane, so that when the moving frame 100 moves, the scraper 300 can block the obstacle in the orbit outside the moving frame 100, thereby making the roller 110 smoothly pass through the orbit.

The casing 210 has been seted up first opening 211 on being close to the terminal surface of scraper blade 300, has been seted up second opening 212 on the bottom surface of casing 210 to first opening 211 and second opening 212 UNICOM, during the installation, people need with scraper blade 300 threaded connection on the casing 210 is close to a terminal surface of first opening 211, and in the installation, people can stretch into the casing 210 through second opening 212 with the palm, thereby make things convenient for people to install scraper blade 300 screw thread on casing 210.

The buffer 400 can be detachably connected to each scraper 300, when the scraper is installed, people need to connect the buffer 400 to the scraper 300 in a threaded manner, and due to the arrangement of the first opening 211, the shell 210 is prevented from abutting against a bolt for installing the buffer 400, so that people can smoothly install the buffer 400 on the scraper 300, and the scraper 300 can smoothly install on the shell 210.

The buffer 400 is made of a rubber material, and the rubber material has certain flexibility, so that when an external object impacts the end of the housing 210, the buffer groove 410 is spirally formed on the side surface of the buffer 400 along the central axis thereof, the buffer 400 can reduce the impact force of the external object, and the possibility that the housing 210 is damaged is reduced.

The movable frame 100 is provided with a connecting plate 240 for installing the lengthening mechanism 200, the connecting plate 240 and the corresponding lengthening mechanism 200 can be welded or detachably connected, the connecting plate 240 and the corresponding lengthening mechanism 200 are connected through at least two fixing plates 250, specifically, when the length of the shell 210 is less than 0.5m, the connecting plate 240 and the shell 210 are in threaded connection, the two fixing plates 250 are welded between the connecting plate 240 and the fixing plates 250, and when the length of the shell 210 is greater than 0.5m, the connecting plate 240 and the shell 210 are welded, the two fixing plates 250 are welded between the connecting plate 240 and the fixing plates 250, so that the connection strength between the connecting plate 240 and the shell 210 meets the installation requirements of people.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
