Abstract
Description
Technical Field
[0001] The utility model relates to the field of equipment fixing devices, in particular to a heavy equipment base fixing and locking device. Background Art
[0002] As we all know, the main component of tire production, rubber, is sheared, squeezed, and plasticized by the rotor of the internal mixer. Since the heavy equipment of the internal mixer will generate large vibrations during operation, the rotor of the equipment itself and the discharge process will generate vibrations, which requires high connection and tightening of the equipment. While ensuring the torque strength of the equipment's own connection, it is important to keep the connection non-loose. If the base of the equipment is loose, abnormal operation will cause irreparable equipment damage, and major equipment accidents are prone to occur. At the same time, the operating accuracy of the equipment cannot be guaranteed after daily loosening, which reduces the service life of the equipment. Summary of the invention
[0003] In order to overcome the deficiencies of the prior art, the utility model provides a heavy equipment base fixing and locking device to reduce the risk of equipment damage caused by loosening due to vibration during the use of the equipment.
[0004] The technical solution adopted by the utility model to solve the technical problem is: a heavy equipment base fixing and locking device is provided with an internal mixer bottom plate and an internal mixer base connecting plate, and is characterized in that a main fastening bolt passes through the internal mixer bottom plate and the internal mixer base connecting plate, a pressure-bearing gasket is sleeved on the main fastening bolt above the internal mixer bottom plate and is screwed into a top screw disc nut, top screw screw holes are evenly distributed on the top screw disc nut, fastening top screws are screwed into the top screw holes, and a fastening nut is screwed on the main fastening bolt below the internal mixer base connecting plate.
[0005] The beneficial effect of the utility model is that the force contact surface between the fastening nut and the bolt is pushed open to within the required pre-tightening force range, the locking nut cannot vibrate and loosen, and the stability of equipment operation is guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS
[0006] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0007] Figure 1 A schematic structural diagram of the utility model.
[0008] Figure 2 It is a top view of the utility model.
[0009] In the figure, 1. main fastening bolt, 2. fastening top screw, 3. top screw disc nut, 4. internal mixer bottom plate, 5. internal mixer base connecting plate, 6. fastening nut, 7. pressure gasket. DETAILED DESCRIPTION
[0010] In the figure, the utility model is provided with an internal mixer bottom plate 4 and an internal mixer base connecting plate 5, a main fastening bolt 1 passes through the internal mixer bottom plate 4 and the internal mixer base connecting plate 5, a pressure-bearing gasket 7 is mounted on the main fastening bolt 1 above the internal mixer bottom plate 4 and is screwed into a top screw disc nut 3, top screw screw holes are evenly distributed on the top screw disc nut 3, a fastening top screw 2 is screwed into the top screw hole, and a fastening nut 6 is screwed on the main fastening bolt 1 below the internal mixer base connecting plate 5.
[0011] The fastening screws 2 on the screw disc nut 3 are gradually tightened in the same direction. After the fastening screws 2 lift the main fastening bolts 1 to reach the expected torque, the rotation of the fastening screws 2 is stopped. The radial force of the bolt threads is borne by multiple fastening screws 2, so that the main fastening bolts 1 cannot be loosened due to vibration, thereby achieving a safe fixing effect and ensuring the stability of equipment operation.
