Description

Technical Field

[0001] The utility model relates to the technical field of asynchronous motors, in particular to an asynchronous motor for a tunneling machine which is convenient to hoist. Background Art

[0002] An asynchronous motor, also known as an induction motor, is a motor that uses alternating current to work. Its core principle is that when the motor is running, the rotating magnetic field in the air gap interacts with the induced current in the rotor winding, thereby generating an electromagnetic torque. This electromagnetic torque is the driving force that propels the motor rotor to rotate, realizing the conversion from electrical energy to mechanical energy. In short, asynchronous motors use the principle of electromagnetic induction to effectively convert electrical energy into mechanical energy and drive the operation of various mechanical equipment.

[0003] In the process of assembling the tunnel boring machine, hoisting the asynchronous motor is a key step. However, one of the challenges currently faced is that the position of the lifting ring on the surface of the asynchronous motor is fixed and cannot be flexibly adjusted according to the lifting requirements. This means that when the length of the lifting rope is not enough to directly place the motor into the tunnel boring machine, we cannot simply shorten the length of the lifting rope by adjusting the position of the lifting ring. This inflexible design reduces the convenience and efficiency of the asynchronous motor during the lifting process to a certain extent, and brings unnecessary trouble to the assembly work.

[0004] Therefore, it is necessary to provide a new asynchronous motor for a roadheader that is convenient for lifting to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides an asynchronous motor for a tunnel boring machine which is convenient for hoisting.

[0006] The utility model provides an asynchronous motor for a tunnel boring machine that is convenient for lifting, comprising: an asynchronous motor body, a motor base and a liquid cooling tank, wherein the motor base is fixedly mounted on the surface of the asynchronous motor body, and the liquid cooling tank is arranged on the inner wall of the motor base; an adjusting mechanism, wherein the adjusting mechanism is symmetrically mounted on the upper surface of the motor base and is used for auxiliary lifting, and the adjusting mechanism comprises an adjusting mounting groove, a first bidirectional screw rod, a moving block and a lifting ring body.

[0007] The adjusting mechanism is rotated to control the lifting ring bodies to move closer or farther from each other, and the use length of the lifting rope is adjusted, thereby improving the convenience of the asynchronous motor. The coolant enters the liquid cooling tank to cool the started asynchronous motor body.

[0008] Preferably, the upper surface of the motor base is symmetrically provided with adjustment mounting grooves, the inner wall of the adjustment mounting groove is rotatably connected to a first bidirectional screw rod, the inner wall of the adjustment mounting groove is symmetrically slidably connected to a moving block, and the threaded surface of the first bidirectional screw rod is meshedly connected to the inner wall of the circular groove of the moving block, and the upper surfaces of the two moving blocks are fixedly connected to a lifting ring body.

[0009] The first bidirectional screw rod rotates on the inner wall of the adjusting installation groove, and the threaded surface of the first bidirectional screw rod contacts the inner wall of the circular groove of the moving block, driving the moving blocks closer to each other, driving the lifting ring bodies closer to each other, and the first bidirectional screw rod rotates in the opposite direction, driving the lifting ring bodies away from each other.

[0010] Preferably, rotating wheels are fixedly connected to both sides of the first bidirectional screw.

[0011] Rotating the rotating wheel drives the first bidirectional screw rod to rotate on the inner wall of the adjusting installation groove, providing drive for the rotation of the first bidirectional screw rod, and facilitating the control of the lifting ring bodies to move closer to or farther away from each other.

[0012] Preferably, a movable mounting groove is provided on the surface of the motor base near the liquid cooling tank, an injection pipe is symmetrically fixedly connected to the surface of the motor base near the liquid cooling tank, and the interior of the injection pipe is connected to the interior of the liquid cooling tank, a sealing block is symmetrically slidably connected to the inner wall of the movable mounting groove, and the clamping block part of the sealing block is slidably connected to the clamping groove of the injection pipe.

[0013] The coolant enters the liquid cooling tank through the injection pipe at the top to cool the asynchronous motor body. The heated coolant is discharged through the injection pipe at the bottom. When the asynchronous motor body is closed, the sealing block slides along the inner wall of the movable mounting groove, and the blocking part of the sealing block enters the slot of the injection pipe to seal the injection pipe, so that the coolant cannot enter the liquid cooling tank.

[0014] Preferably, the inner wall of the movable installation groove is rotatably connected to a second bidirectional screw, and the threaded surface of the second bidirectional screw is meshedly connected to the inner wall of the circular groove of the sealing block, and the upper and lower surfaces of the second bidirectional screw are fixedly connected to a driving block.

[0015] Rotate the drive block to drive the second bidirectional screw to rotate on the inner wall of the movable installation groove. The threaded surface of the second bidirectional screw contacts the inner wall of the circular groove of the sealing block, driving the sealing blocks to move closer to or away from each other, and the sealing block block part enters or moves away from the groove of the injection pipe.

[0016] Preferably, the liquid cooling tank adopts a wave-shaped design.

[0017] The contact area between the coolant and the surface of the asynchronous motor body is increased, which facilitates and quickly takes away the heat generated when the asynchronous motor body is started, and improves the cooling efficiency of the asynchronous motor body.

[0018] Preferably, the edge of the motor base is provided with rounded corners.

[0019] The friction force at the edge of the motor base is reduced. During the lifting process, when the edge of the motor base contacts the inside of the tunnel boring machine, the wear on the inner wall of the tunnel boring machine is reduced.

[0020] Preferably, the motor base is made of stainless steel.

[0021] Stainless steel material has high physical strength and excellent plasticity, which facilitates the rapid processing and molding of the motor base. When the surface of the motor base is squeezed or collided, the surface of the motor base will not easily wear or dent, thereby increasing the service life of the motor base.

[0025] 2. A second bidirectional screw is rotatably connected to the inner wall of the movable installation groove, and the threaded surface of the second bidirectional screw is meshed with the inner wall of the circular groove of the sealing block. The upper and lower surfaces of the second bidirectional screw are fixedly connected with a driving block.
