Description

Technical Field

[0001] The utility model relates to the field of motors, in particular to a motor used on a shortened tunneling machine and requiring to bear the pushing and pulling forces of an oil cylinder. Background Art

[0002] With the development of machinery in my country's coal industry, the main tunneling machinery in my country's efficient tunneling operations is the cantilevered tunneling machine, which will develop in the direction of heavy, large and powerful in the future. Although heavy cantilevered tunneling machines are still in the experimental stage in my country and are mainly used for large-section rock tunnel operations, the trend of domestic coal production towards high efficiency and safety remains unchanged. my country's coal mining equipment will develop in the direction of heavy, large and powerful, which makes the structure and power requirements of explosion-proof motors for tunneling machines more and more stringent. Most of the traditional flameproof three-phase asynchronous motors for tunneling machines have two support lugs at the non-axle extension end of the motor, which are used to support the rotating center axis of the motor to the up and down movement of the cutting head part, such as Figure 1 In order to further meet the working conditions, it is necessary to reduce the size of the tunnel boring machine.

[0013] Figure 1 , Figure 2 Among them, 9-rotating shaft, 10-cylinder, 11-motor, 1-machine base support ear, 13-connecting sleeve, 12-cutting head;

[0014] A motor base ear structure capable of transmitting cylinder thrust comprises a motor base 2, on which a motor outer plate 7 is arranged, and a cutting head 12 is arranged at the left end of the motor base 2. The invention is characterized in that a circular through hole 71 is arranged on the motor outer plate 7, and a circular stop platform 1a is arranged at the end of the base ear 1, wherein the circular stop platform 1a is arranged in the same shape as the circular through hole 71, and the circular stop platform 1a and the circular through hole 71 are welded together to form a whole.

[0015] A high reinforcing rib 3 is arranged on one side of the base support ear 1 close to the cutting head, and short reinforcing ribs 5 are welded on the other side surfaces.

[0016] An open enclosure plate 6 is welded around the reinforcing ribs on one side close to the cutting head.

[0017] The working principle of the utility model is: under the extension and retraction action of the oil cylinder, the force is transmitted to the machine base support ear. After the motor as a whole is connected to the main engine, it drives the reducer at the front end and the cutting head of the tunnel boring machine to move up and down, thereby realizing the movement requirement of the tunnel boring machine from top to bottom or from bottom to top during operation. This increases the structural strength requirement of the machine base of the motor. At the shaft extension end, the support ear part is transferred to the motor casing to shorten the overall length. At the same time, reinforcing ribs and enclosures of different structures are welded to ensure the strength of the overall structure. Since the machine base support ear is subjected to the thrust from the oil cylinder, the thrust of the oil cylinder also acts directly on the motor casing, driving the cutting head to move up and down, simplifying the motor structure while ensuring the transmission efficiency of the oil cylinder thrust.
