The clamping mechanisms 4 on each positioning device are four and are respectively distributed on one side opposite to the vertical supporting mechanism 2 and the left side and the right side of the transverse supporting mechanism 4, and the four clamping mechanisms 4 respectively correspond to the four corners of the box-type precast beam reinforcement cage so as to clamp and fix the reinforcement.
The clamping mechanism 4 comprises an annular fixed disc 401, an annular driving groove 402 is formed in the fixed disc 401, an inner gear ring 403 is concentrically arranged in the driving groove 402, the inner gear ring 403 is rotationally connected with the fixed disc 401, and the upper end face of the inner gear ring 403 is lower than the upper end face of the fixed disc 401. A plurality of pinion gears 404 which are evenly distributed are meshed on the inner gear ring 403, and the pinion gears 404 are in rotary connection with the bottom surface of the driving groove 402, so that the pinion gears 404 are driven to rotate through the inner gear ring 403. The height of the pinion 404 is greater than the height of the ring gear 403, and the upper end surface of the pinion 404 is higher than the upper end surface of the fixed disk 401. Each pinion 404 is correspondingly meshed with a rack 405, and a plurality of racks 405 are slidably connected with the upper end face of the fixed disc 401. Since the height of the upper end surface of the ring gear 403 is lower than the height of the upper end surface of the fixed disk 401, a certain distance exists between the rack 405 and the ring gear 403, and the rotation of the ring gear 403 is not hindered. And each of the racks 405 is disposed in the radial direction of the fixed disk 401 such that each of the racks 405 faces the center of the fixed disk 401. The end face of the rack 405 is connected with clamping blocks 407 through connecting columns 406, one side of each clamping block 407 facing the center of the fixed disc 401 is of an arc-shaped structure, and the steel bars are clamped among a plurality of clamping blocks 407.

The fixing plate 401 is provided with a connecting seat 410 on the circumferential side, and the clamping device 4 is connected to the nut housing 2042 and the nut seat 304 through the connecting seat 410.
A limiting rod 411 is also respectively connected between the clamping mechanisms 4 positioned at the upper side and the lower side. Since the upper clamping mechanism 4 needs to be adjusted in height along the vertical supporting mechanism 2, and the lower clamping mechanism 4 needs to be adjusted in distance along the horizontal supporting mechanism 3, in this embodiment, two ends of the limiting rod 411 are hinged to the upper and lower clamping mechanisms 4 respectively, so as to adapt to the angle change occurring when the upper and lower clamping mechanisms 4 are adjusted. The cross section of the stop lever 411 may be triangular, rectangular or other prismatic, which is not particularly limited by the present invention. As another alternative embodiment, both ends of the limit lever 411 are respectively connected with two clamping mechanisms 4 located at the upper and lower sides through ball joints. Through setting up gag lever post 411, both can adapt to and go on corresponding regulation between the clamping mechanism 4 of upper and lower both sides, can play the spacing effect to clamping mechanism 4 again, prevent that clamping mechanism 4 from beating with nut cover 2042 or nut seat 304, play the effect of guide rail.
In order to facilitate adjustment of the clamping mechanism 4 on the positioning device on the same horizontal line, so that the steel bar is always parallel to the horizontal plane, a laser positioning instrument is arranged on the nut sleeve 2042 of one positioning device, a positioning groove 205 is arranged on the nut sleeve 2042 of the other positioning device, the positioning groove 205 and the laser positioning instrument are oppositely arranged, and when laser of the laser positioning instrument just falls into the positioning groove 205, the front positioning device and the rear positioning device are positioned on the same horizontal line, so that horizontal calibration is conveniently realized.
The working principle is that when the box-type precast beam reinforcement cage inner formwork installing and positioning device is used, a plurality of positioning devices are firstly adjusted to be positioned on the same horizontal line through the laser positioning device and the positioning groove 205 on the positioning devices, then the adjusting handle 2043 and the starting motor 303 are respectively rotated according to the size of a precast beam to be manufactured, the angle and the distance between the plurality of clamping mechanisms 4 are adjusted, or when the distance between the clamping mechanisms 4 on the left side and the right side is required to be increased, the telescopic rods 305 between the two screw rods 301 can be extended by moving the distance between the two vertical supporting mechanisms 2, then four reinforcing bars at four corners of the reinforcement cage inner formwork can be respectively clamped in the clamping mechanisms 4, the plurality of positioning devices erect the reinforcing bars in parallel and are then bundled and built by matching with other reinforcing bars.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
