specific Embodiment approach 1

[0016] Specific implementation mode one: combine figure 1 and figure 2 Describe this embodiment, the large-output self-locking automatic connection mechanism described in this embodiment includes a first rotating block 1, a limit block 2, an expansion sleeve 3, a worm 4, a worm wheel 8, a camshaft 9, and a second rotating block 10. Movable hook 11, two worm bearing seats 5, two return springs 6, two spring connecting rods 7 and two camshaft seats 12, the first rotating block 1, the limit block 2, the expansion sleeve 3 and the second Two rotating blocks 10 are arranged on the camshaft 9 successively from top to bottom, and the junction of the second rotating block 10 and the camshaft 9 is an eccentric shaft 9-1, and the purpose of the eccentric shaft 9-1 is for when the movable hook 11 reaches the position, The eccentric shaft 9-1 continues to rotate, and the first rotating block 1 and the second rotating block 10 are pulled back to the locked state. The upper and lower ends...

specific Embodiment approach 2

[0017] Specific implementation mode two: combination figure 2 To illustrate this embodiment, a vertical rod 7 - 1 is provided above the outer end of the spring connecting rod 7 in this embodiment, and the vertical rod 7 - 1 is used to fix the reset spring 6 . Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0018] Specific implementation mode three: combination figure 2 The present embodiment is described. In this embodiment, the distance between the first axis M-M of the camshaft 9 and the second axis N-N of the eccentric shaft 9-1 is 10 mm to 50 mm. This distance can ensure that when the movable hook 11 reaches the position of the eccentric shaft 9-1, the eccentric shaft 9-1 continues to rotate, and the first rotating block 1 and the second rotating block 10 are pulled back to the locked state. Other compositions and connections are the same as those in Embodiment 1 or 2.

Abstract

The invention relates to an arc-shaped rail docking mechanism and discloses a large-output self-locking type automatic connecting mechanism aiming at solving the problem that deflection exists in the docking and locating manner that grooves in the head end and the tail end of two rails are utilized for splicing and locating in existing rail docking. A first rotating block, a limiting block, an expansion sleeve and a second rotating block are sequentially arranged on a camshaft from top to bottom. An eccentric shaft is arranged on the connection portion between the second rotating block and the camshaft. The upper end of the camshaft and the lower end of the camshaft are connected with two camshaft seats in a rotating mode respectively. Fixed pins are fixedly arranged on the end face of the first rotating block and the end face of the second rotating block on the same side respectively. Spring connection rods are fixed to the end face of the first rotating block and the end face of the second rotating block on the other side respectively. A reset spring is fixed to each spring connection rod. The camshaft is sleeved with a worm wheel through the expansion sleeve. The axis of a worm is arranged perpendicular to the axis of the camshaft. The two ends of the worm are arranged in worm bearing pedestals respectively. The worm is meshed with the worm wheel. The large-output self-locking type automatic connecting mechanism is applicable to docking of the two arc-shaped rails.

Description

technical field [0001] The invention relates to an arc track docking mechanism, in particular to a large output self-locking automatic connection mechanism. Background technique [0002] In nuclear power plants, since the nuclear fusion reactor is a circular cavity, the equipment needs to enter the remodeling cavity during reactor maintenance. Since the load is as heavy as 4t, an arc-shaped track is built, which requires very high requirements for the docking of the track. Strictly, the track docking mechanism must have strong fixing ability and simple operation mode, which is conducive to the support and repeated installation of the track, and also puts forward higher requirements for the compactness of its structure. The existing arc track docking is Use the grooves on the head and tail ends of the two rails for splicing and positioning. This kind of docking positioning is only rough positioning, the positioning performance is not good, and deviations are prone to occur, w...
