Embodiment Construction
[0020] In order to illustrate the present invention more clearly, the present invention will be further described below in conjunction with preferred embodiments and accompanying drawings. It should be understood by those skilled in the art. The content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.
[0021] see figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 and Figure 6 , in the embodiment of the present invention, a drag-type self-balancing round hole holer is proposed, which is characterized in that the hole holer includes: a wire rope 1, a wire rope bayonet 2, a wire rope interface 6, a drill bit 3, a torque motor, a pressure Buffer mechanism, universal joint 16, anti-twist mechanism and armored cable 23, the central axis of described steel wire rope 1, steel rope interface 6, drill bit 3, torque motor and pressure buffer mechanism are all located on the same axis; T...

The invention discloses a drag and drop type self-balancing round hole reaming perforator and belongs to the field of non-excavation crossing construction. The drag and drop type self-balancing roundhole reaming perforator comprises a steel wire rope, a steel wire rope bayonet, a steel wire rope joint, a drill, a torque motor, a pressure buffer mechanism, a universal joint, a reverse twisting mechanism and an armor cable. The upper part of the pressure buffer mechanism is connected to the torque motor and is connected to the reverse twisting mechanism located on the lower part of the pressurebuffer mechanism through the universal joint; the upper part of the torque motor is connected to the drill; and the lower part of the reverse twisting mechanism is connected to the armor cable. The drag and drop type self-balancing round hole reaming perforator balances a reaction torque generated by the drill which drills by means of a reverse twisting knife in the reverse twisting mechanism anda friction force generated by contact with a hole wall and self-balance of torque of the perforator is achieved, so that the perforator completes a task of connecting two existing holes in a state ofonly applying pull of the steel wire rope for completing a penetrating operation.
Description
technical field [0001] The invention belongs to the field of non-excavation crossing construction, and relates to a through-hole device, in particular to a drag-type self-balancing round hole through-hole device. Background technique [0002] In construction projects, it is often necessary to connect various prefabricated cement prefabricated parts together. In actual work, it is often encountered that there are internal hollow passages in the cement prefabricated parts that need to be connected, and these passages are generally reserved for pipes placed inside them. However, in the pouring work of cement prefabricated parts, there is often a certain positioning deviation in the channel reserved by each prefabricated part and is not in an accurate position. Therefore, when connecting the cement prefabricated parts, since the hollow passages of each section cannot be accurately connected, it will lead to the problem that the preset pipeline cannot be laid. In response to th...
