Specific embodiment
As shown in Figure 1, a kind of headstock gear protective device, screw rod 2 are mounted on headstock gear 1, it is welded in the lower end of screw rod 2
Upgrade block 3, connecting rod 4 is symmetrically hinged on upgrade block 3, and the lower end of each connecting rod 4 is hinged with assembly sea 8, the sliding card of assembly sea 8
It connects in the upper end of gate 10, and is provided with Buffer Unit 6 in assembly sea 8.
As shown in Fig. 2, Buffer Unit 6 includes cushion collar 601, cushion collar 601 is connected in assembly sea 8, and cushion collar
601 are internally provided with buffer spring 602 and top plate 603, and the both ends of buffer spring 602 are against assembly sea 8 and top plate 603 respectively
Opposing sidewalls on, top plate 603 is being welded with buffer bar 604, the telescopic end of buffer bar 604 away from the side of buffer spring 602
Level is socketed on rubber pad 5 after cushion collar 601, and assembly sea 8 is specially L shape, L-shaped vertical portion and connecting rod 4
Lower end is hinged, and L-shaped horizontal component sliding is connected on gate 10, and specifically, the lower surface of L-shaped horizontal component is provided with
The sliding rail of swallow-tail form is provided with and the sliding slot that has swallow-tail form sliding rail to match in 10 upper surface of gate.The open end of cushion collar 601
It is threadedly attached on the side wall of L-shaped vertical portion.When gate 10 drops to lowest position, headstock gear 1 continues to drive
Screw rod 2 declines, and screw rod 2 drives assembly sea 8 to slide along the upper end of gate 10 towards two sides by the decline of drive upgrade block 3,
Until buffer bar 604 drives rubber pad 5 to be against on the side wall of floodgate sliding rail 9, it is sliding that power of the screw rod 2 to gate 10 is distributed to gate
On the side wall in road 9, in the prior art, screw rod 2 pushes gate and can be formed to connection bolt or connecting pin to be squeezed effective solution
Shearing leads to the problem of connecting bolt or connecting pin fracture.
As shown in figure 3, there are gaps for gate 10 and river bed in order to prevent, guarantee the leakproofness of gate 10 and river bed, in lock
The upper surface of door 10, which is provided with, holds down assembly 7, and holding down assembly 7 includes fixing seat 701 and clamping sleeve 705, and fixing seat 701 passes through spiral shell
Bolt is mounted on the upper surface of gate 10, clamping sleeve 705 is welded in fixing seat 701, and clamping sleeve 705 is internally provided with pressure
