Self-propelled underground boring jumbo

Abstract

The invention provides a self-propelled underground boring jumbo. The jumbo comprises a rack, a platform, an upper platform, transition platforms, a cross beam, a travelling mechanism and cantilevers and the like, wherein the rack is an open-web-type frame and arranged on the travelling mechanism, the cross beam is arranged on the rack, the platform is arranged on the cross beam, the two side end parts of the platform in the width direction thereof are connected to the rack through brackets, an arc orbit and a cantilever are respectively arranged on the platform and at the two ends of the platform along the length direction of a tunnel, the upper platform is arranged above the platform, a transition platform is respectively arranged above the platform and on the left and right sides of the a position below the upper platform, and a hoisting device is arranged between the cantilevers at the two ends of the platform and below the upper platform. The jumbo is reasonable in structure and low in manufacturing cost, and can solve the traffic problem in tunnels, achieve an effect of synchronously carrying out boring, transportation and other operations, reduce the repeated installation of boring equipment and the transportation and removal of framed bents, increase the constructable distance of boring equipment, increase the time of boring operation, greatly improve the operating efficiency, and shorten the construction period.

Description

Technical field: [0001] The invention relates to a self-propelled tunnel drilling trolley, which is mainly used in the technical field of tunnel construction, especially for the drilling operation of long-distance and large-size diversion tunnel construction projects. Background technique: [0002] At present, in the domestic water conservancy and hydropower industry, the drilling construction of large-scale water diversion tunnels uses the construction mode of scaffolding and drilling equipment. This mode of construction method involves repeated installation and handling of drilling equipment, and the construction distance of drilling equipment is short. , and continuously set up bent frames, move drilling equipment, lay cables and pipes, dismantle bent frames, etc., which greatly increased the ineffective construction time, thus causing problems such as long construction period, large resource investment and high cost, and scaffolding bent in The tunnel occupies a consider...

Problems solved by technology

[0002] At present, in the domestic water conservancy and hydropower industry, the drilling construction of large-scale water diversion tunnels uses the construction mode of scaffolding and drilling equipment. This mode of construction method involves repeated installation and handling of drilling equipment, and the construction distance of drilling equipment is short. , and continuously set up bent frames, move drilling equipment, lay cables and pipes, dismantle bent frames, etc., which greatly increased the ineffective construction time, thus causing problems such as long construction period, large resource investment and high cost, and scaffolding bent in The tunnel occupies a considerable space, and transport vehicles cannot pass through during drilling construction, causing space interference between drilling operations and transport vehicles, affecting the facilities and other materials required for tunnel construction, and interfering with other processes Serious, resulting in delays in work due to traffic in the tunnel, greatly reducing work efficiency, increasing project investment and labor intensity, resulting in low efficiency, long construction period, and at the same time, the use of scaffolding has great safety hazards, so it cannot be adapted to long-distance, large-size tunnels. Construction requirements, it is necessary to seek advanced, practical and low-cost construction facilities
