[0026] Please refer to Figures 1 - 5 , a truss positioning and clamping tooling, which includes a carrier assembly. The carrier assembly includes a base 2 and two bases 3 fixedly connected to the bottom of the base 2 at the front and back. The carrier assembly is cooperatively installed on the track 1 through the bases 3. A clamping device is arranged on the base 2. The clamping device includes a first clamping seat 4, a second clamping seat 5 and a clamping driving mechanism. The clamping driving mechanism drives the second clamping seat 5 to move in the front-back direction, so that the first clamping seat 4 and the second clamping seat 5 clamp the truss 6 together.

[0027] Continue to refer to Figure 3 , in an embodiment of the present utility model, the first clamping seat 4 includes a first support seat 400 and a first clamping plate 401 connected vertically. The first support seat 400 is horizontally arranged, and the first clamping plate 401 is vertically arranged. The two form an L-shaped structure. The first support seat 400 is used to support the truss 6, and the first clamping plate 401 is used to limit the truss 6 from the side. The second clamping seat 5 includes a second support seat 500 and a second clamping plate 501 connected vertically. The second support seat 500 is horizontally arranged, and the second clamping plate 501 is vertically arranged. The two form an L-shaped structure. The second support seat 500 is used to support the truss 6, and the second clamping plate 501 is used to limit the truss 6 from the side.

[0028] Continue to refer to Figures 1 - 3 , in an embodiment of the present utility model, the clamping driving mechanism includes a first screw rod 7. One end of the first screw rod 7 is rotatably matched with the first clamping seat 4, and the other end is screwed with the second clamping seat 5. The first clamping seat 4 and the second clamping seat 5 are connected as a whole through the first screw rod 7. Rotating the first screw rod 7 can drive the second clamping seat 5 to move away from or close to the first clamping seat 4. The clamping device further includes an adjustment driving mechanism, and the adjustment driving mechanism drives the first clamping seat 4 to drive the second clamping seat 5 to move together in the front-back direction.

[0029] Continue to refer to Figures 1 - 3 , in an embodiment of the present utility model, the adjustment driving mechanism includes a second screw rod 8. One end of the second screw rod 8 is rotatably connected to the base 2, and the other end is screwed with the first clamping seat 4. Rotating the second screw rod 8 can drive the first clamping seat 4 and the second clamping seat 5 to adjust their positions together in the left-right direction.

[0030] Continue to refer to Figures 1 - 3, in an embodiment of the present utility model, the clamping device further includes a slide rail 9 laid on the base 2 in the front-rear direction, and the first clamping seat 4 and the second clamping seat 5 are respectively slidably engaged with the slide rail 9 through sliders 10.

[0031] Continue to refer to Figure 1 and Figure 2 , in an embodiment of the present utility model, a row of centering auxiliary pulleys 11 are respectively arranged on the left and right of the base 2. Each row includes a plurality of centering auxiliary pulleys 11 arranged at intervals in the front-rear direction. The clamping device is located between the two rows of centering auxiliary pulleys 11. The centering auxiliary pulleys 11 are used to support the truss 6 to enable the truss 6 to move smoothly.

[0032] It should be noted that the tops of the first support seat 400 and the second support seat 500 are slightly higher than the tops of the centering auxiliary pulleys 11. When the truss 6 is placed on the present utility model, it is jointly supported by the first support seat 400, the second support seat 500, and the centering auxiliary pulleys 11. The weight of the truss 6 is very large, which will cause the tops of the first support seat 400 and the second support seat 500 to drop to the same height as the tops of the centering auxiliary pulleys 11. In this way, the first support seat 400 and the second support seat 500 will share more weight, reduce the burden on the centering auxiliary pulleys 11, and facilitate the movement of the truss 6. The tops of the first support seat 400 and the second support seat 500 can be increased in height by adding cushion plates, which can reduce the wear of the truss 6 on the first support seat 400 and the second support seat 500.

[0033] Continue to refer to Figure 5 , in an embodiment of the present utility model, a parking mechanism is arranged on the base 3, and the carrier assembly can adjust its position on the track 1 and lock the position of the carrier assembly through the parking mechanism.

[0034] Specifically, an adjustment pulley 12 for cooperating with the track 1 is arranged on the base 2. The parking mechanism is preferably a third screw 13, which is used to press against the end face of the adjustment pulley 12 to make the adjustment pulley 12 unable to rotate.

[0035] Among them, the bottom of the base 3 has a chute, the adjustment pulley 12 is located in the chute, the upper end of the track 1 has a rib, and the rib is inserted into the chute and cooperates with the adjustment pulley 12. The present utility model avoids derailment by arranging the chute.

[0036] In the present utility model, the first screw 7 and the second screw 8 of the present utility model are both manually adjustable structures, and in other embodiments, an electrically adjustable structure driven by a motor can be adopted.

The structure composed of the centering auxiliary pulley 11, third screw rod 13, and adjusting pulley 12 is used to assist the truss in clamping and centering work and adjust the distance between the two toolings on the track 1 to meet the centering requirements of trusses of different lengths of escalators.

[0038] The structure of the present utility model is simple, compact, easy to install, safe and reliable. The usage process is as follows:

[0039] Lift the truss 6 of the escalator above the track 1 by a crane, move the two truss positioning and clamping toolings to adjust the distance so that they can be distributed at both ends of the truss 6. Place the truss 6 on the two truss positioning and clamping toolings by the crane, then adjust the front and rear positions of the truss 6 on the track 1 by moving the two truss positioning and clamping toolings. Tighten the third screw rod 13 to fix the position of the truss positioning and clamping tooling. Then rotate the first screw rod 7 to clamp both sides of the bottom of the truss 6 with the clamping seat, and then rotate the second screw rod 8 to adjust the centering position of the truss 6. Finally, measure and finely adjust the second screw rod 8 to complete the centering work.
