During construction, a suitable positioning opening 21 can be selected according to an actual welding position.
Adjusting screw 3 includes the spacing screw head, with the support screw body that spacing screw head is connected, with support screw body other end integrated into one piece's screw thread regulating body, and with the adjusting nut that the cooperation of screw thread regulating body was used. The Contraband shape frame roof and Contraband shape frame bottom plate are opened and are supplied the screw rod through-hole that the support screw rod body passed, lower support plate 1 is opened and is had with the height control hole that screw thread adjusting body cooperation was used.
And a positioning frame height adjusting reference ruler 6 for adjusting the height of the auxiliary positioning frame is further arranged on the top surface of the beam piece.
And the traveling system is connected with the discharging bin and is used for driving the discharging bin to move back and forth. The traveling system comprises supports 41 arranged on two sides of the beam piece, a traveling rail 42 arranged at the top of each support 41, a traveling wheel 43 connected with the traveling rail 42 in a matched mode, and a driving motor 44 connected with the traveling wheel 43, wherein the traveling wheel 43 is connected with the bottom of the lower supporting plate 1. The material discharging bin can be freely controlled to move back and forth and stop at a required position through the traveling system.
The emptying bin is located beam piece both sides and still is connected with operation platform, operation platform installs the operation chair, operation platform still be equipped with the speed regulation footboard that driving motor 44 is connected. The operation personnel can drive the discharge bin in the operation platform and move, and the moving speed of accessible speed adjustment footboard control discharge bin, for example, when speed adjustment footboard steps on to the end the moving speed of discharge bin is the fastest, discharge bin moving speed slows down when loosening speed adjustment footboard, and discharge bin stops moving when loosening speed adjustment footboard completely. The operating position of the operating platform is longitudinally staggered with the positioning frame, the width of the top surface of the beam piece is generally 230 cm, and an operator can directly weld the shear rib through the operating platform and the bracket 41.

A construction method of a shear rib positioning trolley comprises the following steps: step 1, calculating the welding height, the welding longitudinal position and the welding transverse position of the shear bar according to a drawing.
And 2, adjusting the mounting height of the positioning frame according to a drawing to adapt to the welding height of the shear rib in the step 1. The method specifically comprises the step 21 of enabling support screw bodies of two adjusting screws 3 to respectively penetrate through screw through holes at two ends of a v-shaped frame body 2, connecting thread adjusting bodies of the adjusting screws 3 with corresponding height adjusting holes of a lower support plate 1 through adjusting nuts, and enabling the relative rotation number of the adjusting nuts to be the same as that of the thread adjusting bodies.
And step 22, adjusting the reference ruler 6 according to the height of the positioning frame and adjusting the lift-shaped support body 2 to the required height through the adjusting screw rod 3. The engaging force between the adjusting nut and the thread adjusting body is kept constant all the time, the thread adjusting body moves upwards relative to the adjusting nut when the adjusting nut rotates forwards, and the thread adjusting body moves downwards relative to the adjusting nut when the adjusting nut rotates backwards. The edge of the adjusting nut can be provided with a finger pinching part which is convenient for manually rotating the adjusting nut.

And step 23, adaptively connecting the v-shaped support body 2 with the lower supporting plate 1 through the rest adjusting screws 3, wherein the adjusting nuts move on the thread adjusting bodies to adjust the relative positions of the adjusting nuts and the lower supporting plate, the engaging force between the adjusting nuts and the thread adjusting bodies is generally small, and the rest adjusting screws 3 are used for increasing the total connecting force to enable the positioning frame to be connected with the lower supporting plate 1 more firmly.
And 3, moving the positioning frame to the longitudinal position to be welded of the shear rib in the step 1 in a longitudinal front-back sequence through the traveling system. Assuming that the front-back movement direction of the positioning frame is longitudinal, the positioning frame is just located at the longitudinal initial end, the positioning frame height adjusting reference ruler 6 can be arranged at the two transverse sides of the longitudinal initial end, and the positioning frame is used for adjusting the height at the longitudinal initial end.
And 4, welding the shear ribs with the top surface gluten of the beam piece according to the transverse welding position of the shear ribs, and repeating the steps 3 to 4 to complete the welding of all the shear ribs. Specifically, step 41 is included to determine the positioning opening 21 corresponding to the welding transverse position to be welded of the shear rib.
And step 42, putting the shear rib into the positioning opening 21 of the bottom plate of the Contraband-shaped frame and enabling the top of the shear rib to be abutted to the top plate of the lift-shaped frame.
And 43, welding the shear ribs with the top surface gluten of the beam piece in an arc welding mode, and repeating the steps 41 to 43 to complete the welding of all the shear ribs at the same longitudinal position of the shear rib welding. After the shear bar is placed into the positioning opening 21 by hand, the hand is not loosened and the shear bar is welded to the gluten immediately by arc welding. And after the transverse row of shear ribs are welded, replacing the longitudinal welding position until all the shear ribs are welded. The utility model provides a positioning trolley needs two operation personnel when using, and the welding efficiency of shear rib has also improved the twice at least.
And stacking the shear bars to be welded into a discharging bin before the step 1, the step 2 or the step 3, so that the shear bars can be conveniently taken by operators, and the operation efficiency is improved.
The above-described embodiments are merely illustrative of the preferred embodiments of the present invention and do not limit the spirit and scope of the present invention. Various modifications and improvements of the technical solutions of the present invention may be made by those skilled in the art without departing from the design concept of the present invention, and the technical contents of the present invention are all described in the claims.
