Problems solved by technology

Since the diameter of the TBM shield body exceeds 8m and the weight is more than 680 tons, when the cylindrical shield body slides forward on two slide rails with a height of less than 28cm, it is easy to leave the slideway and roll to both sides and become unstable.
It will cause damage to the equipment and tools such as the door crane in the expanded excavation hole, and cause injury to the construction operators on site, which is a very serious safety hazard.

Embodiment 1

[0035] see Figure 1-6 , TBM shield body anti-rolling walking support device, which includes a floor 17 laid at the bottom of the tunnel expansion section, the middle part of the bottom plate 17 is fixedly installed with a raceway 11, and the two outer sides of the raceway 11 are symmetrically arranged. Road 10, the outer sides of the two slideways 10 are respectively provided with symmetrically arranged rails 9; the tops of the raceways 11, slideways 10 and rails 9 support the front shield 5 of the shield body, and the bottom of the front shield 5 The anti-roll support wheel box 4 for preventing the shield body from rolling sideways is installed symmetrically on both sides, and the bottom of the anti-roll support wheel box 4 forms a sliding fit with the track 9; It is connected with the traction power device that drives it to walk along the raceway 11, the slideway 10 and the track 9. By adopting the invention, the construction problem that the shield body of the cylindrical...

Embodiment 2

[0045] Adopt the using method of any described TBM shield body anti-rolling walking supporting device, it comprises the following steps:

[0046] Step1: Lay the bottom plate 17 on the bottom of the tunnel, and fix the raceway 11, slideway 10 and track 9 on the bottom plate 17, and support the stick on the top of the raceway 11;

[0047] Step2: Weld and fix the anti-roll support wheel box 4 symmetrically on both sides of the bottom of the front shield lower block 18, and make the steel wheel 33 of the anti-roll support wheel box 4 support on the rail 9;

[0048] Step3: Weld traction lugs 3 symmetrically on both sides of the bottom of the front shield lower block 18;

[0049] Step4: Fix the traction hoist 16 on the bottom plate 17, and wind the traction steel rope 13 of the traction hoist 16 around multiple sets of movable pulleys 1 and fixed pulleys 15, and connect the movable pulley 1 with the anti-twist device through the balance pulley 14. Connect to the traction lugs 3 on ...

Abstract

The invention provides a TBM shield anti-side-rolling walking support device and a using method thereof. The middle portion of a bottom plate is fixedly mounted with a rolling way, and slide rails aresymmetrically arranged on both outer sides of the rolling way. The outer sides of the two slide rails are respectively provided with symmetrically arranged tracks; the top of the rolling way, the slide rail and the track supports the front shield of a shield body, and the bottom two sides of the front shield are symmetrically and fixedly mounted with anti-side-rolling support roller boxes for preventing the shield body from rolling during the moving process. The bottom of the anti-side-rolling support roller boxes are in sliding engagement with the tracks; the front shield is connected to a traction power device for driving the front shield walking along the rolling way, the slide rail and the track. The TBM shield anti-side-rolling walking support device not only solves the constructionproblem of the shield body of the cylindrical TBM tunneling machine easily rolling to the both sides when slipping and walking in the gate tunnel, but also bears part of the front shield load and reduces the pressure of the front shield on the slide rail.

Description

technical field [0001] The invention relates to the field of a dismantling device in a shield hole, in particular to a TBM shield body anti-rolling walking support device and a use method thereof. Background technique [0002] The tunnel diameter of the TBM is 8.13m, the center height of the hole is 4.065m, there is only a 35mm gap between the front shield shell and the hole wall, and only an 80mm gap between the support shield and the hole wall. In such a small excavation hole, it is impossible to dismantle the shield part of the TBM roadheader. Therefore, the shield body must be excavated from the hole diameter of 8.13m, slide and walk 20m forward along the slide rail laid at the bottom of the hole, and walk to The city gate-shaped cave with a roof height of 14.2m was excavated inside. Since the TBM shield has a diameter of more than 8m and a weight of more than 680 tons, when the cylindrical shield slides forward on two slide rails with a height of less than 28cm, it is ...
