Description
Technical field
The utility model belongs to turbine equipment technical field, specifically, being related to a kind of hydraulic turbine blades angle linkage
Mechanism.
Background technique
Operating oil pipe of hydraulic turbine is opened with blade, closing moves up and down, and is laterally referred to by its end bearing end cap, two sides
Shank and upright sliding bar drive displacement sensor activity, realize blade unlatching, the acquisition and feedback of closing angle signal.It is existing to set
Standby middle upright sliding bar bottom is equipped with screw rod, and horizontal pointer is then equipped with the screw hole matched with screw rod, upright sliding bar and horizontal pointer
The rigid connection being screwed between bar using bolt.It is limited to slide bar and the limitation of horizontal pointer shank diameter, the diameter of screw rod is smaller,
Cause the intensity of screw rod not high, screw rod, which is easy to happen, in the process of running fractures, cause speed-regulating system can not carry out blade unlatching,
The acquisition and feedback of closing angle signal, influence the safe and stable operation of unit.
Utility model content
For deficiency above-mentioned in the prior art, the utility model provides a kind of hydraulic turbine blades angle linkage mechanism, adopts
Replace traditional bolt rigid connection with telescopic activity connection, it is strong to improve the structure connected between upright sliding bar and horizontal pointer
Degree eliminates conventional equipment screw rod and is easy the security risk being broken off.
In order to achieve the above object, the solution that the utility model uses is: a kind of hydraulic turbine blades angle linkage machine
Structure, including upright sliding bar, horizontal pointer and connection sleeve, the end of the horizontal pointer is fixedly connected with bearing (ball) cover, described
Connection sleeve is sheathed on the horizontal pointer and is fixedly connected with one end of the upright sliding bar, the other end of the upright sliding bar
It is connect with the mover of displacement sensor.
Further, the connection sleeve includes outer cylinder and bushing, and the bushing is set in the outer cylinder.
Further, resigning rubber layer is equipped between the outer cylinder and the bushing.
Further, the material of the outer cylinder is stainless steel, and the material of the bushing is copper.
Further, the inner wall of the connection sleeve is equipped with limiting groove, is equipped with ball, the company in the limiting groove
Female connector cylinder is abutted by the ball with the peripheral wall of the horizontal pointer.
The beneficial effects of the utility model are:
(1) replace traditional bolt connection sleeve to be set in outside horizontal pointer with telescopic connection, the diameter of sleeve not by
The limitation of horizontal pointer diameter can according to need the certain thickness sleeve wall of setting, between horizontal pointer and upright sliding bar
Connection structure it is firmer, eliminate conventional equipment screw rod be easy the security risk being broken off；
(2) exist since equipment processing and installation has certain error, have certain journey in upright sliding bar motion process
The horizontal displacement of degree is rigidly connected for conventional stud, and bolt will receive the effect of cross shear when equipment is run, and leads to original
Originally thinner screw rod is more easier to fracture, and the utility model replaces traditional rigid connection, upright sliding bar with activity connection
Can transversely pointer length direction it is free to slide, upright sliding bar not will receive the effect of cross shear, and service life of equipment is more
It is long；
(3) for classic screw connection structure, when installation, needs that screw rod is first screwed into screw hole, during being screwed on screw rod
Thread locking glue is applied, finally fixes screw rod and horizontal pointer spot welding, installation is cumbersome, and when the utility model installation, only
It needs to connect sleeve to be set on horizontal pointer, it is easier for installation.

Specific embodiment
The utility model is further described below in conjunction with attached drawing:
The present embodiment provides a kind of hydraulic turbine blades angle linkage mechanisms, as shown in Figure 1, including upright sliding bar 2, laterally referring to
Needle 3 and connection sleeve 4, the horizontal pointer 3 are cylindrical, and the end of horizontal pointer 3 is fixedly connected with bearing (ball) cover 5, institute
Connection sleeve 4 is stated to be sheathed on the horizontal pointer 3 and be fixedly connected with one end of the upright sliding bar 2, the upright sliding bar 2
The other end is connect with the mover of displacement sensor 1.In the present embodiment, the two sides of bearing (ball) cover 5 are symmetrically arranged with two sets of gears
Structure and two displacement sensors 1, displacement sensor 1 are fixedly connected with the outer housing 6 of equipment, and upright sliding bar 2 runs through outer housing 6,
The end of two upright sliding bars 2 is connect with the both ends of 1 mover of displacement sensor simultaneously, and upright sliding bar 2 is symmetrical arranged in place
The two sides of displacement sensor 1.
In order to promote the service life of connection sleeve 4, as shown in Fig. 2, the connection sleeve 4 includes the outer of stainless steel material
Cylinder 41 and copper bushing 42, the bushing 42 are set in the outer cylinder 41.Since upright sliding bar 2 during the motion may
Run-off the straight is equipped with resigning rubber layer 43 between the outer cylinder 41 and the bushing 42, when 2 run-off the straight of upright sliding bar,
It can be to avoid stuck between connector sleeve cylinder 4 and horizontal pointer 3 by the deformation of resigning rubber layer 43.
It is more smooth in order to slide connection sleeve 4 on horizontal pointer 3, as shown in Figure 3 and Figure 4, the connection sleeve 4
Inner wall is equipped with limiting groove 44, and ball 45 is equipped in the limiting groove 44, and the connection sleeve 4 passes through the ball 45 and institute
