Description
Technical Field
The invention belongs to the field of foundation excavation of power transmission towers, relates to a foundation excavation reaming technology of the power transmission towers, and particularly relates to a multi-tool reaming device which can realize efficient reaming and cutting of drilling without large equipment and meet the foundation excavation technical requirement of the power transmission towers.
Background
The transmission tower is the main support unit for overhead transmission lines. It is not only required to carry heavy transmission lines from the ground at a sufficient safety height, but it is also capable of withstanding a wide variety of natural disasters. It is very sensitive to inclination deformation and has high requirement for uneven settlement of foundation. The common structural form of the transmission tower foundation comprises an independent foundation, an enlarged foundation and a pile foundation, and the structural form of the transmission tower mainly adopts a steel structure. However, like some northern areas, coal mines are relatively more, and goafs exist underground. So that the conventional power transmission iron tower and foundation structure are difficult to adapt to the ground surface movement of the goaf at present, and the power transmission iron tower is possibly inclined or even overturned. The original scheme is to drill holes with the depth of 10 meters and the diameter of 1.8 meters from the ground to the underground to fix the power transmission tower foundation. For the above reasons, it is currently required to expand the hole with the original diameter of 1.8 m to the hole with the diameter of 2.4 m at the depth of about 8 m, and the depth of the hole is 2 m, so that the firmness of the iron tower base can be increased by adopting the method that the diameter of the hole of the base is increased, and the iron tower is prevented from tipping. The internal expanding of the underground hole has a great technical problem, and the hole expanding is realized by using large-scale expanding equipment. However, most of the power transmission towers are on the field uphill, the terrain is complex, the environment is bad, and large-scale equipment is difficult to directly use. At present, pile foundation reaming of a power transmission tower is achieved by adopting small-sized working equipment such as a small excavator and a loader, and equipment such as a Luoyang shovel is refitted on the basis, so that pile foundation excavation is achieved, and a manual reaming mode is adopted. The manual excavation mode has hidden dangers such as efficiency and personnel safety, so that the equipment technology for reaming and excavating the power transmission tower is urgently needed.
In order to solve the underground hole expanding requirement, most of the devices depend on large equipment, such as an authorized bulletin number CN 101315021B, and Chinese patent publication date 2011.11.02 discloses an automatic diameter-changing reaming drilling tool, when the automatic diameter-changing reaming drilling tool works, a diameter-changing connecting rod mechanism needs to be opened by the acting force of a large equipment drilling machine, a cutter is arranged on the connecting rod mechanism, and the cutting efficiency is low. Similarly, the Chinese patent with the grant publication number of CN 104763328B and the grant publication date of 2017.03.08 discloses a hydraulic reaming circulation drilling machine and a reaming pile construction process thereof, wherein large-scale equipment of a crane is utilized to support a guide rail through a hydraulic column, a reaming tool is arranged on the guide rail, and a reaming drill bit is hydraulically driven to ream. Therefore, the method must be used in large equipment such as a crane, a drilling machine and the like, and cannot be used in a reaming and cutting environment of the transmission tower.
Although some prior art does not use large-scale equipment, the device has problems, such as the grant publication number is CN 102003146B, chinese patent publication date is 2012.12.12 discloses a full hydraulic reamer, the inner end of a reamer blade is provided with an incomplete gear, the gear is meshed with a rack with an internal structure, the displacement of a pump is changed to open the reamer blade, and although the device does not use large-scale equipment, the device is complex to operate and can work normally only by controlling the pump pressure and the drilling pressure. When the device is used, the device falls into a plurality of limiting steel balls through pressure to normally work, one steel ball needs to be thrown into a drill rod from the ground to seal an oil way, the inertia of the thrown steel ball is large in a deep hole, and if the thrown steel ball is large, other parts and the device are easily damaged, so that the stability and the reliability of the whole device are affected, and the device cannot normally work. Similarly, the chinese patent with the grant publication number CN 104806170a and grant publication date 2015.07.29 discloses a drilling and coal mining large-diameter-variable reaming bit, which can realize diameter-variable reaming, but has a complex structure, and also needs to strictly control different oil pressures to perform actions, and needs oil pressure to control steel balls to perform actions, so that misoperation is easy to occur. Also, for example, chinese patent publication No. CN 107083923B, publication No. 2019.02.19 discloses a variable diameter reaming tool, in which the position of the cam is controlled by hydraulic oil, so that the reaming tool is opened, but the tool has a complex structure and high requirements.
The existing underground hole reaming devices are mostly large-scale equipment and cannot meet the application requirements of power transmission towers, so that the multi-tool reaming device is provided, can ream holes in established vertical holes, meets the small-scale excavation requirements of the power transmission towers, can be used as accessories, and is suitable for most of iron tower construction in north of China.
