As shown in Figure 1, the tunnel steel arch frame I-steel grabbing device of the present embodiment, including girder 1 and can on girder 1
The walking beam 2 of stretching motion is connected between girder 1 and walking beam 2 by spring 3.
As shown in Fig. 2, girder 1 and 2 bottom of walking beam are uniformly provided with several L shape hooks, the L shape hook 5 and walking beam 2 of girder 1
The L shape hook 4 of bottom is oppositely arranged, when so that girder and walking beam relative motion are to a certain position, 2 bottom of girder 1 and walking beam
L shape hook cooperation, tunnel steel arch frame I-steel is picked up.
As shown in Figure 1, girder 1 includes two sides angle steel 1.1 disposed in parallel, 1.1 bottom both ends of angle steel are respectively arranged on connection
On plate 1.2, the angle steel 1.1 of 1.2 top of connecting plate is equipped with square steel 1.3, and square steel 1.3 and angle steel are equipped with baffle between 1.2 middle part
1.4, as shown in Figure 1,3.
Walking beam 2 includes two sides angle steel 2.1, and both ends are equipped with round steel 2.2 between two sides angle steel 2.1, wherein side round steel 2.2
Neighbouring angle steel is equipped with square steel 2.4, and angle steel 2.1 moves on connecting plate 1.2, and side round steel both ends 2.3 are connect with the other side
The corresponding both ends 1.5 of plate are equipped with spring 3, girder 1 and walking beam 2 and pass through on the baffle 1.4 and walking beam 2 on girder 1
The round steel 2.2 of side and the square steel 2.4 of the other side limit.
As shown in Fig. 2, being symmetrically arranged with several lifting hole(eyelet)s 1.6 on girder 1, it is symmetrically arranged with several lifting hole(eyelet)s 2.5 on walking beam 2, leads to
Cross the lifting of hawser 6.
In the present embodiment, L shape hook height is 25cm, and the maximum distance of 2 relative motion of girder 1 and walking beam is 30cm.It is main
1.1 height of angle steel of beam 1 is 120cm, and 2.1 height of angle steel of walking beam 2 is 100cm.The angle steel length of girder 1 and walking beam 2

Steel plate used in embodiment is Q235 steel plate.
The manufacturing process of the utility model is as follows:
Two 1.5cm thickness connecting plates 1.2 are put to neat, length 120cm, centre distance 80cm side by side first；Then by two
1.1 12 × 10 × 1.5cm of ∠ of root angle steel is placed on connecting plate 1.2, and beyond angle steel 1.1 is shorter and 1.2 outside of connecting plate is right
Together, it is then welded on connecting plate 1.2；L shape hook 5 is welded on 1.1 corner of angle steel simultaneously, middle centering distance is about
30cm。
After the completion of girder 1 welds, the assembling of walking beam 2 is carried out, 2 assembling mode of walking beam is with 1 mounting means of girder, wait live
After dynamic beam angle steel 2.1,1.2 plates of connection and L shape hook 4 install, the welding of 2 upper end connecting cross beam of walking beam, connecting cross beam are carried out
The round steel 2.2 of both ends 48 × 4mm of diameter, square steel 2.4 is having a size of 40 × 4mm in the outer part.Then walking beam 2 is placed under girder
On portion's connecting plate 1.2, and two 1.3 40 × 4mm of square steel are welded on the angle steel 1.1 of girder 1, four block baffles 1.4 are distinguished
It is welded on girder connecting plate 1.2 and top square steel 1.3, limits walking beam scope of activities.
Finally L shape hook 4, L shape hook 5 are welded on girder 1 and walking beam 2, and spring 3 installed, hole for hoist can thing
