Description
Technical field
The utility model relates to mining ventilating tunnel operational monitoring field, specifically a kind of oval clip Wind tunnel sensor.
Background technology
The air duct that impact during downhole blasting and air quantity instability produce swings, and is easy to cause damage, and easily causes false alarm to existing Wind tunnel sensor, simultaneously in air duct extension process, during mobile Wind tunnel sensor, cramp frame easily misplaces, and causes false alarm.Due to Wind tunnel sensor false alarm, the master switch fail secure caused can have a significant impact switch application life, also can form the mindset of " false alarm ", likely cause security incident to field personnel's thought.In addition, existing Wind tunnel sensor must according to the change of air duct diameter, and frequent air duct of changing presss from both sides, and reduces worker productivity.
The unreasonable structure existed for existing Wind tunnel sensor, self suspension arrangement easily damage, the problem such as false alarm, reduction staffing effectiveness, are necessary to develop a kind of economy, general, reliable and stable Wind tunnel sensor.
Summary of the invention
The problems that the utility model exists for existing Wind tunnel sensor, provide a kind of oval clip Wind tunnel sensor.
The utility model is achieved through the following technical solutions: oval clip Wind tunnel sensor, comprise the anti-explosion terminal box built with tongue tube, permanent magnet, also comprise the support frame of rectangular U-shaped structure, place two adjusting bolts slided in support frame left side central portion elongated slot from left to right, the gripper shoe at longitudinal bracing (fore-and-aft direction shown in Fig. 1) middle part before and after support frame, is connected to two jig arm below gripper shoe by hinge
Permanent magnet is fixedly supported between two adjusting bolts, and gripper shoe all laterally has a sliding tray up and down, and anti-explosion terminal box is by it is fixed in gripper shoe with the spacing bolt be slidably matched of sliding tray;
Two jig arm strutted are downward opening more than half ellipsoidal structure, and the top of this more than half ellipsoidal structure is keep off with support frame bottom surface the plane connecing and coordinate, and the major axis of this more than half ellipsoidal structure and support frame bottom surface perpendicular.
During concrete use, the above-below direction of permanent magnet relative to anti-explosion terminal box is controlled by two adjusting bolts of sliding, anti-explosion terminal box is regulated to control the right position of anti-explosion terminal box relative to permanent magnet relative to the right position of gripper shoe, spacing between the two and relative position adjustable, be convenient to the best induction point finding both, guarantee the stability, adjustability, the versatility that use.To the impact of anti-explosion terminal box and damage when the setting of gripper shoe reduces downhole blasting, reduce false alarm.And the structure of permanent magnet and anti-explosion terminal box longitudinal left and right installation, at utmost solve the problem of false alarm, ensure that the reliability and stability of warning.Two jig arm of more than half ellipsoidal structure ensure that the utility model is applicable to the air duct of various diameter, avoid the problem frequently changing air duct folder because of the change of air duct diameter, improve the operating efficiency of employee.
Oval clip Wind tunnel sensor novel structure described in the utility model, to be skillfully constructed, at utmost to solve the problem of false alarm, ensure that the reliability and stability of warning; Avoid the problem frequently changing air duct folder because of the change of air duct diameter, improve the operating efficiency of employee.

In figure: 1-anti-explosion terminal box, 2-support frame, 3-adjusting bolt, 4-permanent magnet, 5-gripper shoe, 6-bearing pin, 7-jig arm, 7a-presss from both sides rod, 8-sliding tray, 9-balancing weight, 10-iron chains, and 11-links up with.
Detailed description of the invention
Oval clip Wind tunnel sensor, comprise the anti-explosion terminal box 1 built with tongue tube, permanent magnet 4, also comprise the support frame 2 of rectangular U-shaped structure, place two adjusting bolts 3 slided in support frame 2 left side central portion elongated slot from left to right, the gripper shoe 5 at longitudinal bracing middle part before and after support frame 2, to be articulated and connected two jig arm 7 below gripper shoe 5 by bearing pin 6
Permanent magnet 4 is fixedly supported between two adjusting bolts 3, and gripper shoe about 5 all laterally has a sliding tray 8, and anti-explosion terminal box 1 is by it is fixed in gripper shoe 5 with the spacing bolt be slidably matched of sliding tray 8;
Two jig arm 7 strutted are in downward opening more than half ellipsoidal structure, and the top of this more than half ellipsoidal structure is keep off with support frame 2 bottom surface the plane connecing and coordinate, and the major axis of this more than half ellipsoidal structure and support frame 2 bottom surface perpendicular.
During concrete enforcement, two jig arm 7 are all that the folder rod 7a be arranged in parallel by front and back two-phase is formed.Reduce the weight of jig arm 7 self.
Further, two jig arm 7 Basolateral are fixed with a balancing weight 9 respectively.During concrete enforcement, the weight of balancing weight 9 can be regulated according to wind tube wind quantity, add the stability of Wind tunnel sensor.
Further, described support frame 2 and gripper shoe 5 overhung are connected with iron chains 10 and the hook 11 for suspending in midair.By regulating the use length of iron chains 10, regulating the suspension height of Wind tunnel sensor when ensure that down-hole uses according to the suspension situation of air duct in certain limit easily, improve practicality of the present utility model; And this flexible suspension structure is avoided, because impact during downhole blasting is to the damage of Wind tunnel sensor, enhancing environmental suitability.
