[0040] Embodiment 2

[0041] like Figure 8As shown, compared with Example 1, another implementation of the present invention is: a plurality of long hairs 43 are fixedly connected to the bottom surface of the elastic push plate 35, and the bottom surface of the long hairs 43 slides with the bottom surface of the transverse slide groove 5; when working, the elastic push plate 35 jumps and slides along the bottom surface of the transverse slide groove 5, driving the long hairs 43 to clean the bottom surface of the transverse slide groove 5, and the wind blown away by the airbag 36 further improves the cleanliness of the inside of the transverse slide groove 5.

[0042] During operation: the lifting platform 4 is lowered to the ground under the drive of the motor, and the staff places the I-beam to be installed on the top surface of the lifting platform 4, pushes the column 7 to drive the transverse slide 6 to slide along the transverse slide groove 5, and when the transverse slide 6 slides inside the transverse slide groove 5, it drives the moving roller 34 to roll, drives the elastic push plate 35 to slide in accordance with the transverse slide groove 5, and pushes away the stones that fall into the transverse slide groove 5, and the elastic push plate 35 is subjected to the friction force of the bottom surface of the transverse slide groove 5, so that the elastic push plate 35 is bent, squeezing the airbag 36, so that the gas in the airbag 36 is ejected from the air nozzle 37, and the dust on the bottom surface of the transverse slide groove 5 is blown away; when the elastic push plate 35 is bent to the point where the elastic force is greater than the friction force, the elastic push plate 35 is reset, driving the airbag 36 to be reset, and the outside air is sucked into the airbag 36 from the air nozzle 37;

[0043] After the columns 7 on both sides are close to the placed I-beam, the internal threaded sleeve 9 is rotated to move the internal threaded sleeve 9 out of the storage groove 8, and the screw rod 10 is rotated to make the screw rod 10 move out of the internal threaded sleeve 9, align the block 11 with the slot 12, push the block 11 into the slot 12, and continue to rotate the nut 14 to drive the screw rod 10 to move out of the internal threaded sleeve 9, push the top seat 13 close to the base 15, so that the spring telescopic rod 16 is compressed, and the column 7 is supported and fixed, which improves the stability of the I-beam on the top surface of the lifting platform 4; at the same time, when the block 11 is inserted into the slot 12, the hollow capsule 17 is squeezed and compressed, pushing the elastic rod 20 to slide into the sliding hole 19, so that the No. 1 spring 21 is compressed, and the air inside the hollow capsule 17 is ejected from the air hole 18 to blow away the dust in the slot 12, thereby reducing the probability of the block 11 detaching from the slot 12;

[0044] At the same time, when the internal threaded sleeve 9 is rotated out of the storage groove 8, the pull rope 25 is pulled out from the connecting hole 24, and the isosceles trapezoidal slider 23 is driven to slide upward, so that the No. 3 spring 30 is stretched, and the isosceles trapezoidal slider 23 pushes the trapezoidal blocks 26 on both sides to slide to both sides, so that the No. 2 spring 29 is compressed. When the trapezoidal block 26 approaches the side wall of the horizontal slide 5, it pushes the movable rack 32 to engage with the fixed rack 31, and fixes the horizontal slider 6 inside the horizontal slide 5, thereby further improving the stability of the column 7, and then improving the safety of the I-beam during transportation.

[0045] After the column 7 is fixed, the staff uses the sleeve handle to rotate the screw 40, driving the vertical slider 39 to slide downward along the vertical slide groove 38, driving the pin block 42 to slide downward, and the inclined surface of the pin block 42 squeezes the side of the I-beam, so that the I-beams are squeezed close to each other, further reducing the probability of shaking when the I-beam moves; after the I-beam is fixed on the top surface of the lifting platform 4, the motor drives the lifting platform 4 to rise, the crawler 2 drives the trolley frame 1 to move to the installation area, and the arch frame installation mechanism 3 installs the I-beam, reducing the probability of the I-beam falling during transportation and improving the safety of installation.

Figure 1 As a benchmark, according to the person's observation perspective, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
