DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in combination with the embodiments of the present invention and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] like Figure 1-4 As shown, a preferred embodiment of the present invention provides a connection and support structure for a shield machine connecting bridge, including a connection structure A, wherein the connection structure A includes a connection seat 1 and a traction seat 2. The connection seat 1 is fixed on the trailer 3, and the traction seat 2 is fixed on the connecting bridge 4. The connection seat 1 and the traction seat 2 are detachably connected to connect the trailer 3 and the connecting bridge 4 together. And a support structure B, wherein the support structure B includes a support frame 5 and a rubber support block 6. The support frame 5 is fixed on the trailer 3. The rubber support block 6 is attached to the connecting bridge 4. The rubber support block 6 can slide relative to the support frame 5.

[0027] The connecting seat 1 includes a first support plate 11 and a second support plate 12. The first support plate 11 is fixed vertically on the trailer 3, and the second support plate is fixed on the trailer 3 in an inclined shape. A first connecting plate 13 is fixed on the first support plate 11, and a second connecting plate 14 is fixed to the first support plate 11 below the first connecting plate 13. The traction seat 2 is fixed on the connecting bridge 4 and can be located between the first connecting plate 13 and the second connecting plate 14. The first connecting plate 13, the second connecting plate 14 and the traction seat 4 are connected together by a pin 7. A first mounting hole is provided on the first connecting plate 13, a second mounting hole is provided on the second connecting plate 14, and a third mounting hole is provided on the traction seat 4. The positions of the first mounting hole, the second mounting hole and the third mounting hole correspond to each other, and the pin 7 extends through the first mounting hole, the second mounting hole and the third mounting hole in sequence, thereby connecting the first connecting plate 13, the second connecting plate 14 and the traction seat 4 together. After the pin 7 connects the connecting bridge 4 with the trailer 3, this large-span connecting bridge 4 can stably adapt to various tunnel constructions. The diameters of the first mounting hole, the third mounting hole, and the second mounting hole are 5 mm larger than the outer diameter of the pin 7. The gaps between the pin 7 and the first mounting hole 131, the third mounting hole 141, and the second mounting hole 41 allow the connecting bridge 4 to work normally under a slope. A locking plate 8 is also provided at a position close to the pin 7 on the first connecting plate 13 to fix the pin 7. The pin 7 includes a plug-in portion and a cap portion. When the pin 7 is plugged and fixed in the first mounting hole, the second mounting hole, and the third mounting hole, the locking plate 8 abuts between the cap portion and the plug-in portion of the pin 7 to fix the pin 7. The locking plate 8 is detachably fixed to the first connecting plate 13 by bolts 81 and washers.

[0028] The top surface of the support frame 5 is a horizontal plane. The rubber support block 6 is fixed on the crossbeam of the connecting bridge 4 by bolts 61 and washers and is located between the crossbeam of the connecting bridge 4 and the support frame 5, so that the crossbeam of the connecting bridge 4 is supported on the support frame 5 by the rubber support block 6 and can slide relative to the top surface of the support frame 5. The rubber support block 6 is a square structure, and the upper surface is inlaid with a first steel plate 63 fixed to the crossbeam of the connecting bridge 4, and the lower surface is inlaid with a second steel plate 64 supported by the support frame 5. The rubber block in the middle has a certain amount of deformation and bearing capacity, so that the connecting bridge 4 does not have a hard contact between steel and steel when the tunnel has a large slope. The rubber support block 6 can slide on the support frame 5. This design solves the displacement generated by the connecting bridge 4 rotating around the connecting pin 7 of the trailer 3 and the connecting bridge 4 when turning. A total of four rubber support blocks 6 are arranged under the front and rear end support beams of the connecting bridge 4. Since the weight of the connecting bridge 4 and the auxiliary equipment on it is very large, four support points are set to share the total weight of the connecting bridge 4. The rubber support block 6 is designed to be detachable, which is convenient for overall installation and replacement. The lower surface of the second steel plate 64 embedded at the bottom of the rubber support block 6 is a processed surface, and grease is applied during installation. When the shield machine turns, since the entire connecting bridge 4 needs to slide relatively on the trailer 3 with the help of the second steel plate 64 at the bottom of the rubber support block 6, this surface is processed to reduce friction and grease is applied during installation.

[0029] The trailers 3 include two, which are respectively arranged at the two ends of the connecting bridge 4 and can be connected to the connecting bridge 4. The supporting structure includes four groups, and the connecting structure includes two groups. The steel plate surface on the top of the supporting frame 5 is a processed surface, and reinforcing ribs are welded on the front and rear of the steel plate.

[0030] The method of using the connection and support structure for the shield machine connecting bridge of this embodiment is as follows: first, the rubber support block 6 is bolted to the four fulcrum positions under the cross beam of the connecting bridge 4 with bolts 61, and then the connecting bridge support frame 5 is spot welded and fixed on the two trailers 3 that have been placed in position according to the designed position, and then the connecting bridge 4 that has been connected with the rubber support block 6 is dropped as a whole onto the fixed connecting bridge support frame 5, and after being laid flat, the trailer welding connecting seat 1 and the connecting bridge traction seat 2 are connected together with the pin shaft 7, and after the pin shaft 7 is fixed with the locking plate 8, the trailer welding connecting seat 1 is welded to the trailer 3 according to the adjusted position. After the rubber support block 6 is combined under the supporting cross beam of the connecting bridge 4, the entire connecting bridge 4 can slide freely on the upper surface of the connecting bridge support frame 5 through the second steel plate 64 at the bottom of the rubber support block 6 under the action of traction. The sliding range of the upper surface of the connecting bridge support frame 5 meets the movement amount of the supporting cross beam of the connecting bridge 4 of the shield machine under the minimum turning radius.
