[0022] Example 1: This embodiment provides a method for quickly replacing the existing drive system of a bridge inspection vehicle. In view of the situation where the drive system of the bridge inspection vehicle 3 is severely corroded but the vehicle body is relatively intact, the arrangement of the inspection vehicle 3 on the bridge is as follows: Figure 1 shown.

[0023] The method described in this embodiment includes replacement of the upstream side and replacement of the downstream side. Taking the upstream side as an example, the method specifically includes the following steps: S1: Construction preparation: Preparation of machinery and materials: including one truck crane 2, two sets of I-beams 8, four sets of hand hoists 9, one set of electric hoists 10, wire ropes and other tools, etc.

[0024] S2: If Figure 1 As shown, a truck crane 2 is arranged on the bridge deck 1 , and the I-beam 8 and related components are lifted to the inspection vehicle 3 by the truck crane 2 .

[0025] S3: If Figure 2 and Figure 3 As shown, four hand hoists 9 are installed at the adjacent track connecting seats 7 in front and behind the upstream gantry 4 of the inspection vehicle 3, and two hanging I-beams 8 are set on both sides of the upstream gantry 4, which are fixed to the body truss rods of the inspection vehicle 3 with clips, and the hook at the bottom of the hand hoist 9 is connected to the hanging I-beam 8 with a wire rope. Then, an electric hoist 10 is installed on the track 6 just above the inspection vehicle 3, and the wire rope is used as a safety device to connect the body of the inspection vehicle 3 to the track 6 on the upstream and downstream sides to prevent the body of the inspection vehicle 3 from falling when the existing drive system 11 of the inspection vehicle 3 is replaced.

[0026] S4: Use the hand hoist 9 to lift the existing drive system 11 running wheel of the upstream inspection vehicle to 5 mm off the track, use the cutting machine to remove the existing drive system 11, lower the dismantled existing drive system 11 onto the inspection vehicle 3, and then transfer it to the bridge deck 1 via the truck crane 2.

[0027] S5: After the existing drive system 11 is dismantled, the electric hoist 10 is used to lift the new drive system connection base 12 to the top surface of the gantry 4 on the upstream side of the inspection vehicle 3, and the position of the new drive system connection base 12 is adjusted. The new drive system connection base 12 is welded to the upstream side gantry 4 on site.

[0028] S6: After the new drive system connecting seat 12 is installed, the new drive system walking mechanism 13 is hoisted to the installation position and assembled on the track 6 on site. After completion, it is connected to the hanging shaft of the new drive system connecting seat 12.

[0029] S7: After the new drive system is installed, the hand chain hoist 9 is loosened so that the running wheels of the new drive system fall on the track 6 to bear the weight of the inspection vehicle 3, thereby completing the replacement of the existing drive system on the upstream side.

[0030] Except that the lifting position and installation position are changed to the downstream side, the replacement method on the downstream side is the same as that on the upstream side. The replacement of the existing drive system 11 on the downstream side is completed in the same order as above, and then the hoisting I-beam 8, hand hoist 9, electric hoist 10 and safety wire rope are removed and transported to the bridge deck 1 together with other tools.
