[0002] The ventilation system of a TBM (Tunnel Boring Machine) is a core device for ensuring tunnel construction safety. It consists of ventilation ducts, fans, dust suppression equipment, etc., and solves problems such as oxygen deficiency, dust accumulation, and excessive levels of harmful gases within the tunnel through forced ventilation. The ventilation ducts are typically made of high-strength flame-retardant composite materials, possessing antistatic and corrosion-resistant properties. They are 0.8-1.5 meters in diameter and connected in sections using quick-connect couplings to ensure airtightness. Dismantling the ventilation ducts usually involves using a work trolley. Traditional work trolleys are mostly fixed structures designed for tracks with a fixed inclination angle. When erected on tracks at different angles, the levelness of the work platform is often low, affecting the dismantling and transportation process of the ventilation ducts. Utility Model Content

Detailed Implementation

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Please see Figure 1-4This utility model provides a ventilation duct dismantling and transportation trolley, including a traveling platform 1 and a working platform 2. The traveling platform 1 has support wheels 3 at the four corners of its lower surface. The working platform 2 has a support frame 4 on its lower surface. The support frame 4 has a support end 5 on one side of its lower surface. The traveling platform 1 has a connecting seat 6 at a position corresponding to the support end 5. The support end 5 is rotatably connected to the connecting seat 6 via a rotating shaft. The support frame 4 has an adjusting plate 7 on the other side of its lower surface. The traveling platform 1 has an adjusting seat 8 at a position corresponding to the adjusting plate 7. The adjusting plate 7 has an adjusting groove 9. The adjusting seat 8 has adjusting bolts 10 passing through the adjusting groove 9 at both ends. The working platform 2 has a guardrail 11 on the outer side of its upper surface.

[0014] In use, support wheels 3 are installed at the lower end of the walking platform 1. The support wheels 3 are pressed against the rail, thereby sliding the entire work trolley onto the rail. The work platform 2 is installed at the upper end of the walking platform 1 via a support frame 4. One side of the support frame 4 is rotatably connected to the connecting seat 6 via a support end 5, thereby rotatably connecting the work platform 2 to the walking platform 1 under the support of the support frame 4.
