Abstract
The utility model discloses a lower horizontal type gate locking device and relates to a lower horizontal type gate locking structure applied to water conservancy and hydropower. The lower horizontal type gate locking device comprises a locking arm welded to a gate, and a first locking hole is formed in the upper end of the locking arm. The locking device further comprises a locking support which is fixed to a gate buttress through a locking burying piece, the locking support comprises two locking plates arranged vertically, each locking plate is provided with a second locking hole, the two locking plates are connected through a connecting plate, the outer side of one locking plate is connected with a locking guide sleeve, the other side of the locking guide sleeve is connected a locking oil cylinder, a piston rod of the locking oil cylinder is connected with a locking pin shaft, the locking pin shaft is arranged in the locking guide sleeve in a penetrating mode, and the free end of the locking pin shaft is inserted in the first locking hole of the locking arm and the second locking holes of the two locking plate in a separable mode. Compared with the prior art, the lower horizontal type gate locking device is simple and effective in structure, convenient to mount, accurate in locking position, high in reliability and good in stability, and locking moment is lowered through the tail end of the locking support.
Description
Technical field
The utility model relates to the lower sleeping gate lock structure that is applied to water conservancy and hydropower.
Background technology
In water conservancy and hydropower industry, locking device is the necessary part of gate safety guarantee, a kind of effectively lock mode, and its quality and safety more and more come into one's own.
When gate entirety is done halted state within the scope of 70 °, headstock gear oil cylinder is failure to actuate, because headstock gear oil cylinder exists internal leakage, when longer in this position time of staying, due to headstock gear load pressure (gate deadweight+water flow pressure etc.) Dynamic Effect etc., headstock gear piston rod glides, and makes to stir work under gate entirety, and serious accident easily occurs.
Existing safe locking device adopts gate lock arm upper end that hydraulic lock assembly is installed and locks, and owing to stretching out arrival lock hole from lock arm side, existing gate latch-up-free device, so cause gate easily to glide.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, provide a kind of latch-up structure more rationally, high, the lock in place lower horizontal gate locking device accurately of safety factor.
The purpose of this utility model is achieved in that lower horizontal gate locking device, comprises the lock arm being welded on gate, and the upper end of described lock arm arranges the first lock hole, described locking device also comprises lock bracket, lock bracket is fixed on gate buttress by locking embedded part, lock bracket comprises two vertical lockplates of arranging, the second lock hole is set respectively on every lockplate, two the second lock holes are arranged on same axis, two lockplates connect by junction plate, the outside of one of them lockplate connects locking guide pin bushing, the opposite side of locking guide pin bushing connects locked cylinder, the piston rod of locked cylinder connects locking bearing pin, locking bearing pin is set in locking guide pin bushing, detachable being plugged in the first lock hole of lock arm and the second lock hole of two lockplates of free end of locking bearing pin.
The utility model, by increasing locked cylinder at lock bracket tail end, increases locking embedded part, lock shaft and locking Hydraulic Station simultaneously.When locking Hydraulic Station obtains after external signal enabling signal, motor action in locking Hydraulic Station, drive hydraulic pump forward fuel feeding to enter locked cylinder rodless cavity, rodless cavity oil-feed piston rod is stretched out forward, and lock shaft is synchronizeed extend action forward by connecting to do with piston rod head end.Lock shaft is inserted in lock arm lock hole through lock bracket (lock bracket plays support lock dead axle), forms mechanical rigid locking.
The utility model is compared with prior art, simple in structure effective, convenient installation, and latched position is accurate, by lock bracket tail end, reduces locking moment, and reliability is high, good stability.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model use occasion.
Detailed description of the invention
As shown in Figure 1, be lower horizontal gate locking device, comprise lock arm 1 and lock bracket 6, the upper end of lock arm 1 arranges the first lock hole 2.Lock bracket 6 is fixed on gate buttress 8 by locking embedded part 7, lock bracket 6 comprises two vertical lockplate 6-1 that arrange, the second lock hole 6-3 is set respectively on every lockplate 6-1, two the second lock hole 6-3 are arranged on same axis, two lockplate 6-1 connect by junction plate 6-2, the outside of one of them lockplate 6-1 connects locking guide pin bushing 5, the opposite side of locking guide pin bushing 5 connects locked cylinder 3, the piston rod of locked cylinder 3 connects locking bearing pin 4, locking bearing pin 4 is set in locking guide pin bushing 5, detachable being plugged in the first lock hole 2 of lock arm 1 and the second lock hole 6-3 of two lockplate 6-1 of free end of locking bearing pin 4.
As shown in Figure 2, at the both sides of gate 10 welding lock arm 1, on the gate buttress 8 of both sides, locking device is installed respectively, gate 10 is driven by headstock gear 9, realizes opening and closing.When locking, stretch out and drive locking bearing pin 4 to put in the first lock hole 2 of lock arm 1 and the second lock hole 6-3 of two lockplate 6-1 by the piston rod of locked cylinder 3, form mechanical rigid locking.
