Detailed Description

For a better understanding of the objects, structures and functions of the present utility model, a linear positioning device for an arch ring on an arch skeleton according to the present utility model will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, the linear positioning device for an upper arch ring of an arch skeleton of the present utility model comprises a main rod 1, wherein one end of the main rod 1 is a scribing part 11, the other end of the main rod 1 is a holding part 12 for holding by hands during scribing, a guiding mechanism 3 is arranged on the holding part 12, the guiding mechanism 3 comprises an extending block 31 formed by outwards extending two sides of the main rod, guiding rods 32 perpendicular to the main rod 1 and parallel to each other are arranged on the extending blocks 31 on two sides, the guiding rods 32 are used for abutting against the outer side of a water-retaining edge template 4, a scribing rod 2 is arranged on the scribing part 11, the scribing rod 2 and the guiding rods 32 are positioned on the same side of the main rod 1, and the arrangement position of the scribing rod 2 is determined by the radian of the water-retaining edge template 4, the distance between the guiding rods 32 and the width of the upper arch ring. By abutting the guide bar 32 against the outside of the water-blocking-edge die plate 4, the upper arch ring line type can be positioned quickly.

In an alternative embodiment, the main rod 1 is detachably and fixedly connected with the guide rod 32, the main rod 1 and the guide rod 32 are provided with positioning grooves which are mutually clamped, and then are fixed by fixing screws 33, and the adjustment of the scribing distance can be realized by arranging a plurality of positioning grooves 13 on the main rod 1 at equal intervals.

The marking rod 2 is detachably and fixedly connected with the main rod 1, the upper part of the marking rod 2 is provided with threads, the marking rod 2 penetrates into a through hole positioning hole 14 arranged on the main rod 1 and is fixed by screwing a fixing nut 21 up and down, a plurality of positioning holes 14 are arranged on the main rod 1 at equal intervals, smaller intervals can be arranged between the positioning holes 14, and the positioning holes are matched with the positioning grooves 13 in an adjusting way, so that the adjustment of the marking distance with higher precision in a larger range can be realized.

Simple and easy positioner's preparation, mobile jib 1 adopts 70cm long 25mm square pipe of wall thickness 1mm, and extension piece 31 adopts 30cm long 25mm square pipe of wall thickness 1mm, and guide bar 32 adopts two 1cm long diameters to be 6mm round steel, and marking off pole 2 adopts a 10cm long diameter to be 6mm round steel, and extension piece 31 symmetry vertical welding is in mobile jib 1's both sides, and guide bar 32 and marking off pole 2 parallel arrangement weld respectively on extension piece 31 and mobile jib 1.
