Description

Technical Field

[0001] This utility model relates to the field of trolley technology, and in particular to a trolley for transporting and installing corrugated steel plates for tunnel reinforcement. Background Technology

[0002] Older highways didn't have ventilation shafts. Now, for tunnels, adding ventilation shafts in the middle and openings on the sides of the existing tunnels requires damaging the original concrete load-bearing structure, necessitating reinforcement. Here, corrugated steel sheets are used, attached to the inside of the tunnel, and then grout is injected.

[0003] Through comparison and optimization of various construction schemes, the steel corrugated plate reinforcement technology for tunnel intersection areas was developed.

[0004] Whether using traditional manual scaffolding or modified arch frame installation vehicles, construction must be carried out while traffic is interrupted.

[0005] Given that traditional installation methods cannot meet the actual needs of steel corrugated plate reinforcement construction in tunnel intersection areas.

[0006] However, using a shield trolley as a protective and construction platform, with manual installation of corrugated steel sheets, resulted in a narrowest point where the shield trolley and the tunnel secondary lining were only about 30 centimeters apart, making it impossible for personnel to operate. Through repeated demonstrations and discussions, the corrugated steel sheet construction equipment was efficiently integrated with the shield trolley.

[0007] This allows for the installation of corrugated steel sheets using a shield trolley under continuous traffic conditions. Utility Model Content

[0043] Construction process of corrugated steel plate integral reinforcement

[0044] Through comparison and optimization of various construction schemes, it was found that the corrugated steel sheet reinforcement process in tunnel intersection areas, whether using traditional manual scaffolding or modified arch frame installation vehicles, requires construction to be carried out under traffic interruption conditions. Given that traditional installation methods cannot meet the actual needs of corrugated steel sheet reinforcement construction in tunnel intersection areas, and that using shield trolleys as a protective and construction platform for manual installation of corrugated steel sheets presents challenges, the narrowest point between the shield trolley and the tunnel secondary lining is only about 30 centimeters, making manual operation impossible. Through repeated demonstrations and discussions, and by efficiently integrating corrugated steel sheet construction equipment with shield trolleys, it was achieved that corrugated steel sheet installation can be carried out using shield trolleys under continuous traffic conditions.

[0045] The overall reinforcement of the corrugated steel sheet is carried out through three main stages: 1. Assembly of the corrugated steel sheet outside the tunnel; 2. Overall transportation of the corrugated steel sheet inside the tunnel; 3. Installation of the corrugated steel sheet. Utilizing a lightweight down-the-hole drill rig and grouting machinery mounted on an installation trolley, the anchor bolts and grouting operations are completed, ensuring that the construction of the corrugated steel sheet at the tunnel intersection can proceed while maintaining normal traffic flow.

[0050] 4. The transport trolley is equipped with a generator set and travels between the tunnel entrance and the middle of the tunnel. Its function is to transport the corrugated steel sheets from outside the tunnel into the installation position inside the tunnel.

[0051] 5. The transport trolley allows slow-moving vehicles to pass underneath without disrupting traffic. The transport trolley is equipped with walkway protection and anti-fall devices to ensure safe passage for vehicles.

[0052] II. Installation trolley

[0054] 2. Lifting and translation devices are installed at the four corners of the gantry.

[0055] 3. A trolley track is designed above the gantry, which can transport the corrugated steel sheet from the transport trolley to the installation trolley via the track.

[0056] 4. The installation trolley is equipped with a corrugated steel plate extension device and a translation device for adjusting the position of the corrugated steel plate.

[0057] 5. The trolley allows slow-moving vehicles to pass underneath without disrupting traffic. The trolley is equipped with walkway safety devices and anti-fall devices to ensure safe passage for vehicles.

[0058] 6. The side walkways on both sides of the installation trolley are designed with hydraulic cylinder pushing devices to push the corrugated steel plate to the designed installation position.

[0059] The walking device includes: 4 solid tires and 2 sets of motor reducers K97-142-4kW-4.

[0060] Beneficial effects:

[0061] Both the transport trolley and the installation trolley are designed to be accessible to other vehicles traveling at reduced speeds. This ensures that traffic can be maintained during the tunnel steel corrugated plate reinforcement construction without interrupting traffic, effectively guaranteeing normal traffic flow within the tunnel, reducing the impact of construction on traffic, and minimizing interference with the surrounding traffic environment and economic activities.

[0062] The transport trolley is designed with walkway protection devices and fall protection devices, providing safety for construction personnel and equipment and reducing safety risks during transportation. At the same time, the transport trolley is equipped with a generator set, which can independently supply power to ensure stable operation inside the tunnel, accurately transporting the corrugated steel sheets from outside the tunnel to the installation location inside.

[0063] The installation trolley gantry is equipped with lifting and translating devices at its four corners, and a trolley track is designed above the gantry for precise adjustment of the corrugated steel sheet position. The side walkways on both sides of the installation trolley are designed with hydraulic cylinder pushing devices, which can accurately push the corrugated steel sheet to the designed installation position, ensuring the accuracy and quality of installation.

[0064] This utility model efficiently integrates corrugated steel sheet construction equipment with a shield trolley, using the shield trolley as a protective and construction platform for corrugated steel sheet installation. This overcomes the limitations of traditional installation methods in tunnel intersection areas, improves construction efficiency, and ensures the safety of construction personnel.

[0065] The vertical lifting mechanism of the trolley is located at the lower part of the trolley gantry, which allows the trolley to be raised and lowered as a whole. This facilitates the adjustment of the trolley to adapt to changes in cross slope and superelevation, ensuring the stability of the trolley under different geological conditions and tunnel slopes, and expanding the scope of application of the equipment.

[0066] The trolley's translation cylinder has a maximum stroke of 100mm and an adjustable stroke of 50mm to the left and right of the tunnel center, which can flexibly adjust the trolley position according to actual construction needs, improving the flexibility and adaptability of construction.

[0067] The installation trolley is equipped with a lightweight down-the-hole drill and grouting machinery, which can complete the anchor bolt locking and grouting operations. It realizes the integration of corrugated steel plate installation and related auxiliary operations, reduces the number of construction equipment and construction procedures, improves construction efficiency, and reduces construction costs.

[0068] Both the transport trolley and the installation trolley are equipped with complete hydraulic systems. There must be no leakage at any pipe joints in the hydraulic systems. The commissioning pressure is as required, and the rated pressure of the hydraulic systems is clearly defined, ensuring stable operation and reliable operation of the equipment. Furthermore, there are clear requirements for adding hydraulic oil before operation, ensuring the normal functioning of the hydraulic systems. Attached Figure Description

The lower longitudinal beams 7 of the transport trolley are symmetrically fixed to both sides of the bottom of the transport trolley gantry column 4 of the transport trolley body 46. A rubber-wheeled traveling device 8 is installed at the bottom of the lower longitudinal beam 7. The traveling device uses solid rubber wheels and is equipped with two sets of motor reducers (K97-142-4kW-4) and a motor drive system. Power is supplied by a generator set 17 installed inside the transport trolley body 46. The top of the transport trolley gantry column 4 is connected to a full-coverage platform 9 via an upper crossbeam 2. A longitudinal connecting beam 14 for the longitudinal trolley is installed between the two upper crossbeams 2, and a longitudinal trolley 10 for the transport trolley is installed on top of the upper crossbeams 2. A top-level platform ladder 3 and a first lateral working platform 5 are configured on both sides of the column 4. A lateral platform ladder 6 is installed on the side of the first lateral working platform 5, and a side-arched corrugated steel plate 13 is fixed via a connecting assembly. The connecting assembly consists of side guide wheels 43 and limiting grooves 44. The side guide wheels 43 are slidably connected to the side of the side arch corrugated steel plate 13. Traveling wheels 45 are installed on the side of the side arch corrugated steel plate 13, and the traveling wheels 45 are embedded in the limiting grooves 44 for guidance. The top of the two side arch corrugated steel plates 13 is fixed with a top arch corrugated steel plate 11, and guardrails 1 are set on both sides of the top arch corrugated steel plate 11. A clearance clearance 12 is maintained between the main body 46 of the transport trolley and the tunnel wall. A vertical hydraulic cylinder 19 of the transport trolley is set at the bottom, and its piston rod is connected to the transport trolley translation device 20 to realize the overall lifting and translation function of the trolley.

The trolley's traveling system uses a cycloidal pinwheel reducer, which requires 220-320 medium-load gear oil before operation. During the first operation of the hydraulic system, 46# anti-wear hydraulic oil needs to be added in multiple stages to ensure the pump station level meets requirements and to purge air from the pipelines. When positioning the trolley, first align the center of the top formwork with the tunnel centerline, then support the side formwork in place.
