Abstract
The utility model discloses a foldable-type anchor rod eye position control instrument, which includes a foldable-type calibrated scale, wherein a position fixing hole is arranged at a folding part; an upwards-opened semicircular clamping groove with the diameter equal to that of the anchor rod is arranged on the calibrated scale on the left side of the folding part; a downwards-opened semicircular clamping groove with the diameter equal to that of the anchor rod is arranged on the calibrated scale on the right side of the folding part; level meters are installed on the left and the right calibrated scales respectively; and both the spaces between the semicircular clamping grooves and the position fixing hole are equal to the row and line space of the anchor rod. The foldable-type anchor rod eye position control instrument has high precision and meets requirements of safety production through quantitatively controlling the row and line space of the anchor rod.
Description
Technical field
The utility model relates to the measurement apparatus.
Background technology
At present when underworkings is beaten anchor pole, adopt the method for range estimation or backguy rope control anchor pole between array pitch, this precision of method is low, be difficult to control array pitch between anchor pole, anchor pole sets not straight, had a strong impact on the construction quality and the supporting intensity in tunnel, the tunnel is yielding, thereby can not satisfy requirement of safe production.
Summary of the invention
The purpose of this utility model is a kind of collapsible square of design position controller.
Technical solutions of the utility model are: it comprises one by collapsible rule, burst is provided with fixed hole, on the rule in burst left side, establish the semicircle draw-in groove that diameter that an opening makes progress equals bolt diameter, on the rule on burst right side, establish the semicircle draw-in groove that a diameter that Open Side Down equals bolt diameter; About install a level meter respectively on two rules; The spacing of above-mentioned semicircle draw-in groove and fixed hole be equal to anchor pole between array pitch.
For the ease of in inclined drift, using, on the rule on burst right side, grade rod is housed.
Below by using method of the present utility model its advantage is described.
During use, at first open two rules of collapsible square position controller, should arrange last root anchor pole and insert fixed hole, and the draw-in groove of burst left-hand scale chi blocked second from the bottom anchor pole, burst right side rule is got to horizontal level, at this moment, the position of right side rule draw-in groove is that the place ahead sets the anchor pole position.
If in inclined drift, use, then will there be an end of grade rod to rush at the position of meeting head on, the other end is arranged groove down have an end of grade rod to find value of slope accurately by rotation, sets anchor pole in the draw-in groove position and gets final product.So adopt the utility model accurate positioning.
Description of drawings
Fig. 1 is the synoptic diagram of the utility model embodiment.
Marginal data: 1-left scale chi; The right rule of 2-; The 3-fixed hole; The 4-level meter; 5,5/-draw-in groove; The 6-grade rod.
Embodiment
As shown in Figure 1, collapsible square of the present utility model position controller comprises the collapsible rule by left scale chi 1 and the right rule 2 hinged length 2m that form, burst is provided with the fixed hole 3 of a diameter 25mm, on left scale chi 1, establish the semicircle draw-in groove 5 that diameter that an opening makes progress equals bolt diameter, on right rule 2, establish the semicircle draw-in groove 5/ that a diameter that Open Side Down equals bolt diameter; And about install a level meter 4 respectively on two rules, on right rule 2, load onto grade rod 6 again; Above-mentioned semicircle draw-in groove 5 and 5/ and the spacing of fixed hole 3 equal anchor pole between array pitch.
Claims (2)
1. collapsible square position controller, it is characterized in that, it comprises a collapsible rule, burst is provided with fixed hole, on the rule in burst left side, establish the semicircle draw-in groove that diameter that an opening makes progress equals bolt diameter, on the rule on burst right side, establish the semicircle draw-in groove that a diameter that Open Side Down equals bolt diameter; About a level meter is housed on two rules respectively; The spacing of above-mentioned semicircle draw-in groove and fixed hole be equal to anchor pole between array pitch.
2. collapsible square as claimed in claim 1 position controller is characterized in that, on the rule on burst right side grade rod is housed.
