Description

Technical Field

[0001] This application relates to the technical field of tunnel drilling and blasting excavation, and particularly to a device for widening the platform of a drilling and blasting jumbo. Background Art

[0002] At present, tunnel construction by drilling and blasting is relatively common. During the drilling and blasting process, a drilling and blasting jumbo is usually used. However, due to the change in the type of tunnel support, the cross-section also changes, and there are defects in the current design of drilling and blasting jumbos. For Class IV and V surrounding rocks, I-beams are usually constructed. Compared with Class III surrounding rocks with better surrounding rocks, the width increases by at least 15 cm. If there is further influence from the lining, the difference in the excavation cross-section for different surrounding rocks will become relatively large, reaching 80 - 90 cm on one side. At the same time, drilling construction must be carried out close to the rock wall, resulting in the steel frame jumbo having difficulty in dealing with different excavation cross-sections, being unable to adapt to the cross-section changes of different surrounding rocks for excavation, and having limitations in the construction scope. Summary of the Utility Model

[0025] As shown in the figure, the platform widening device of the drill and blast jumbo includes: platform main beam 1, support plates 4, platform pipes 3, and steel bar meshes. The platform main beam 1 is connected to the jumbo column 2. Four support plates 4 are vertically installed at the bottom of the platform main beam 1, and the support plates 4 are erected at equal intervals on the same horizontal line. Installation holes are opened in the center of the support plates 4, and the four installation holes are on the same horizontal line. The platform pipes 3 pass through the installation holes and are inserted into the support plates 4 to be connected to the support plates 4. Limiting holes are opened on the platform pipes 3 and on the platform main beam 1 inside the support plates 4. The platform pipes 3 and the platform main beam 1 are connected by inserting pins 5 through the limiting holes. Threads are opened at the tail ends of the pins 5. After the pins 5 are sequentially inserted into the platform pipes 3 and the platform main beam 1, the pins 5 are locked by locking nuts to achieve the fixed connection of the pins 5, the platform pipes 3 and the platform main beam 1. The steel bar meshes are laid on the platform pipes 3 to form a temporary platform.

[0026] Specific implementation method: The drill and blast platform widening device is made of simple materials such as steel plates and steel pipes. Four steel plates with a size of 18*18 cm and a thickness of 5 mm are used. A hole with a diameter of 11 cm is dug in the middle as the support for platform widening. The four steel plates are firmly welded to the main I-beam of the existing platform. Then, a steel pipe with a diameter of 10 cm and a wall thickness of 3.5 mm is passed through the middle of the four steel plates. When excavating a tunnel with a smaller cross-section, the steel pipe is retracted and the existing platform is used for construction. When excavating a tunnel with a larger cross-section, the steel pipe is pulled out, and the protruding steel pipe is supported by two end pads. The end of the steel pipe is fixed with a pin 5. After the steel pipe set on the platform protrudes, a steel mesh is covered on it. After temporary fixation, it can be used as the widened construction platform. After use, the steel mesh platform is removed and the steel pipe is retracted, and then the tunnel with a smaller cross-section can be constructed.

[0027] Finally, it should also be noted that in this article, relationships such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "including", "comprising" or any other variant are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
