Description
Technical field
The utility model is related to gate of hydropower station to control equipment field, more particularly to a kind of aligned with gate hydraulic pressure grasping beam fills
It sets.
Background technology
Hydraulic pressure grasping beam is an important component of power station gantry crane, is the interface that crane is attached with gate
Unit.The contraposition of existing water power hydraulic automatic grabbing beam with two kinds of lower schemes generally by being realized：One is use to be arranged in grasping beam
Contraposition signal device above lower lifting lug controls, align the iron core head of signal device by gate lifting eye top plate withstand and on
It moves, generates induced current, the signal for stopping declining is sent out to door machine when induced current reaches the minimum value of range so that at this time
The center in the axis pin center alignment gate lifting eye hole of grasping beam.This scheme advantage be to control it is simple, but due to grasping beam have compared with
Big inertia, grasping beam also will continue to decline, and cause grasping beam axis pin center to occur with the case where gate lifting eye hole off(-)center, grab
Even contraposition signal device can be made to collide and damage with gate lifting eye when beam decrease speed is very fast.Another kind is by grasping beam
Upper setting sleeve, be arranged on lock gate leaf it is matched wear pin, when making sleeve fall on to wear on pin, grasping beam axis pin center with
Gate lifting eye hole center is just aligned.The advantages of this scheme, is sleeve and wears pin and can not only be used for alignment device, plays simultaneously
Good guiding role, but contraposition process grasping beam and gate can all be hit every time, since grasping beam has larger matter
Amount, shock dynamics is larger every time, and greater impact, long-term impact meeting can be all caused to grasping beam shaft crossing device and its auxiliary device
Detection sensor in grasping beam can be damaged, it is final to influence contraposition to the cooperation precision for influencing sleeve Yu wearing pin.
Utility model content
The technical problem to be solved by the utility model is to provide one kind can cushion impact forces and can accurately realizing grab
The exactitude position at the axis pin center and gate lifting eye hole center of beam shaft crossing device effectively reduces the collision between grasping beam and gate
Gate hydraulic pressure grasping beam alignment device.
The utility model is realized by the following technical solutions：
Gate hydraulic pressure grasping beam alignment device, including：Grasping beam, the grasping beam lower section are provided with gripping arm, are arranged in the gripping arm
There is biography shaft device；Gate, the gate top are provided with shackle plate；It is particular in that, it is long to offer rectangle in the gripping arm
Hole, is fitted with groove type plate in the rectangle slot hole, the groove type plate upper surface and grabs in space between lower surface and is provided with pressure
Contracting spring；It is provided at the center of the groove type plate and declines presence sensor.
Further, the top of the shackle plate is circular arc body, and the lower surface of the groove type plate is provided with and the circular arc
The circular arc clamping portion of mates.
Further, the upper surface of the groove type plate is provided with the first spring base, and the grasping beam lower surface is provided with second
Spring base, the compressed spring are arranged between the first spring base and second spring seat.
Further, the stepped hole of perforation groove type plate top and bottom is offered at the center of first spring base, it is described
Decline presence sensor to be arranged in the stepped hole.
Compared with prior art, the utility model has the beneficial effects that：
Groove type plate movable up and down is provided in gripping arm, the centre of groove type plate, which is provided with, declines presence sensor,
By the effect of compressed spring, groove type plate is located at the bottom of rectangle slot hole and the position of multiple level marketing contraposition when working normally position.
After grasping beam declined limit, by compressing compressed spring, groove type plate can be made to carry out certain buffering, decline thereon senses in place
Device is moved with the movement of groove type plate, is avoided detection sensor in the prior art and is damaged because the decline of grasping beam is impacted.
Description of the drawings
Fig. 1 is utility model structural schematic diagram.
Specific implementation mode
The embodiments of the present invention are described in detail below, it can be by claim but the utility model is novel
It limits and the multitude of different ways of covering is implemented.
Gate hydraulic pressure grasping beam alignment device, including：Grasping beam 1,1 lower section of the grasping beam are provided with gripping arm 10, the gripping arm 10
On be provided with pass shaft device 11；Gate 2,2 top of the gate are provided with shackle plate 20.In order to solve the technology of the utility model
Problem offers in rectangle slot hole 10`, the rectangle slot hole 10` in the gripping arm 10 and is fitted with groove type plate 12, groove type plate 12
Section configuration is similar to channel steel, it can be ensured that is not fallen off when groove type plate 12 slides in rectangle slot hole 10`.On the groove type plate 12
It is provided with compressed spring 13 in space between 1 lower surface of surface and grasping beam, in order to make compressed spring 13 stablize in above-mentioned sky
In, as a preferred embodiment, can the upper surface of the groove type plate 12 be provided with the first spring base, in 1 lower surface of grasping beam
It is provided with second spring seat, compressed spring 13 is arranged between the first spring base and second spring seat.It is in place in order to facilitate declining
