Description

Technical Field

[0001] The utility model belongs to the technical field of lifting devices, in particular to a slag grab bucket lifting device. Background Art

[0002] The slag grab is a device for picking up materials under the crane. It is usually suspended and moved by the overhead crane to realize the grabbing and transfer of materials between different positions. Its main function is to grab and carry various industrial waste residues such as slag, coal slag, aluminum slag, etc., to ensure the smooth operation of the production line and reduce environmental pollution.

[0003] Slag grabs play an important role in industrial production and become an indispensable material handling equipment due to their high efficiency, strong adaptability, high durability, easy operation and high safety.

[0004] In the prior art, the grab bucket lifting device uses a hydraulic lever to provide power to pull the grab bucket up and down to drive the grab bucket to complete the slag removal operation. However, since the hydraulic rod grab bucket lifting device is exposed to the working environment for a long time, waste slag splashed when the grab bucket is working is likely to remain on the surface of the hydraulic rod, which will contaminate the surface of the hydraulic rod and affect the normal operation of the hydraulic rod.

[0005] To this end, the utility model provides a slag grab bucket lifting device. Utility Model Content

[0006] In order to make up for the deficiencies of the prior art and solve at least one problem raised in the background technology, a slag grab bucket lifting device is proposed.

[0007] The technical solution adopted by the utility model to solve its technical problems is: a slag grab bucket lifting device described in the utility model comprises a hydraulic cylinder, a hydraulic rod is fixedly connected to the bottom of the hydraulic cylinder; a grab bucket bracket is fixedly connected to the bottom of the hydraulic rod; a grab bucket is installed at the bottom of the grab bucket bracket; the side wall of the hydraulic cylinder is fixedly connected; the end is fixedly connected to an injection pipe; the top of the injection pipe is connected to an air inlet; the middle of the injection pipe is connected to an air supply pipe; the end of the air supply pipe is connected to a nozzle; through the above structure, the harm of waste slag generated during work to the hydraulic system and the environment is reduced, and the continuous injection of air to the hydraulic rod also alleviates to a certain extent the influence of high temperature generated when the hydraulic system is working on the hydraulic system; at the same time, the injection can reduce the influence of surface dust on the extension and retraction of the hydraulic rod when it is extended and retracted.

[0008] Preferably, a baffle is fixedly connected to the middle of the jet pipe; the baffle is arranged in an arc shape; the above structural design effectively reduces the phenomenon that when the operator tries to clean the scum attached to the surface of the hydraulic rod during the slag removal operation, the scum is scattered due to the external force. This design optimization significantly reduces the range of scum splashing, thereby providing a safer and cleaner working environment for cleaning work.

[0009] Preferably, the side wall of the baffle is fixedly connected with a spring bracket; the bottom of the spring bracket is fixedly connected with a scraper; the bottom of the scraper is fixedly connected with a rope; the other end of the rope is connected to a grab bracket; when the scraper contacts the baffle for work, the grab bracket moves downward to drive the rope to move synchronously, and at the same time, the rope pulls the scraper to scrape the surface of the baffle. During the extension and retraction of the hydraulic rod, the above structural design can realize the synchronous cleaning of foreign objects adsorbed on the outside of the baffle while the machine performs its work tasks, which not only improves the work efficiency, but also makes the subsequent cleaning work more convenient. This design takes into account the dual factors of work efficiency and cleanliness, ensuring that the machine can keep its surrounding environment clean while working efficiently. It improves the convenience of using the machine.

[0010] Preferably, a plurality of brushes are fixedly connected to the middle of the hydraulic rod; the brushes are arranged in an inverted cone shape; when the grab bracket is working, the brushes can move up and down to sweep off the scum adhering to the hydraulic rod. Through the above structure, when the machine is working, the hydraulic rod is extended and retracted back and forth to drive the brushes to clean the hydraulic rod, thereby ensuring the cleanliness around the hydraulic rod and reducing the jamming problem that occurs when the hydraulic rod is extended and retracted.

[0011] Preferably, a collection box is fixedly connected to the bottom of the hydraulic rod; the collection box is bowl-shaped; when working, the brush sweeps the scum on the hydraulic rod and drops it into the collection box. Through the above structure, the scum falls into the tray after the brush sweeps off the scum, reducing corrosion and wear on the grab bracket and facilitating cleaning.

[0012] Preferably, a telescopic rod is fixedly connected to the bottom of the hydraulic cylinder; the bottom of the telescopic rod is fixedly connected to the grab bucket bracket; during operation, the hydraulic rod moves up and down to drive the telescopic rod to extend and retract back and forth. Through the above structure, the stability of the grab bucket lifting device during operation is increased and the swing of the grab bucket during operation is reduced.

[0013] The beneficial effects of the utility model are as follows:

[0014] 1. The slag grab bucket lifting device described in the utility model reduces the harm of waste slag generated during operation to the hydraulic system and the environment, and continuously sprays air to the hydraulic rod, which also alleviates the impact of high temperature generated when the hydraulic system is working on the hydraulic system to a certain extent; at the same time, the air jet from the air jet pipe can reduce the impact of surface dust on the extension and retraction of the hydraulic rod.

[0015] 2. The slag grab bucket lifting device described in the utility model ensures the cleanliness around the hydraulic rod by driving the brush to clean the hydraulic rod when the hydraulic rod is extended and retracted back and forth when the machine is working, and reduces the jamming problem that occurs when the hydraulic rod is extended and retracted.
