The invention discloses a tire steel cord fabric take-up device which comprises a centering mechanism, a driving mechanism and a travelling mechanism, wherein the travelling mechanism comprises a transport trolley, a lining fabric roll support, a take-up roller and a guide rack; the take-up roller is rotationally connected with the transport trolley; the lining fabric roll support and the guide rack are fixed on the transport trolley; the driving mechanism is in transmission connection with the take-up roller; the centering mechanism comprises a cord fabric centering transport rack, a rectification module and a transverse moving module; the rectification module comprises a main cylinder, a support, a rectification roller and a driver for driving the rectification roller to swing; the transverse moving module comprises guide rails and a moving platform; the moving platform is connected with the guide rails in a sliding way; the cord fabric centering transport rack and the rectification module are mounted on the moving platform. Through the tire steel cord fabric take-up device, the transportation, loading and unloading processes of steel cord fabric are simplified, the labor intensity of workers is reduced, and the working efficiency is improved.

The invention discloses a construction method and structure for a vertical shaft. The vertical shaft construction method comprises the steps of digging a draw shaft horizontally from a bottom roadway or a bottom underground chamber to the earth surface or above, wherein the draw shaft has multiple fold line segments and the whole body of the draw shaft moves upward along the center line of the vertical shaft; according to the stabilization and fixation condition of surrounding rocks, conducting segment blast on the draw shaft. According to the construction method and structure for the vertical shaft, the complexity of the construction process of the vertical shaft can be reduced, the construction of the vertical shaft is more simple and convenient, and the construction cost of the vertical shaft is reduced.

The invention discloses an armored cable type electromagnetic impact rotary drilling tool for polar subglacial bedrock, which includes a cuttings chamber, a water pump, a driving motor, an electromagnetic impact system, an outer pipe of the drilling tool and a drill bit, wherein the cuttings chamber is assembled on On the upper part of the water pump, the liquid outlet of the cuttings chamber is set corresponding to the liquid inlet of the water pump. The driving motor is arranged at the lower part of the water pump. The bottom is connected with the electromagnetic impact system, and the electromagnetic impact system is driven by the hollow shaft to work. Both the hollow shaft and the electromagnetic impact system are assembled in the inner cavity of the outer tube of the drilling tool, and the hollow shaft and the outer tube of the drilling tool are connected through a reducer , the bottom of the outer tube of the drilling tool is connected to the drill bit, beneficial effects: the electromagnetic impact system is added, which effectively makes up for the shortcomings of the traditional armored cable-type electric mechanical drilling tool that cannot drill into the rock formation due to insufficient drilling pressure and torque, and reduces the risk of broken rock difficulty.

The invention relates to a faceplate-type tool used for motor base fine turning. The faceplate-type tool used for motor base fine turning comprises a machine head connecting disk and a cutter bar installed on a cutter post. The outer side of the machine head connecting disk is provided with a locating plate parallel to the machine head connecting disk. A plurality of uniformly distributed connecting pillars are arranged between the machine head connecting disk and the locating plate, and the other side of the locating plate is provided with a faceplate pressing plate parallel to the locating plate. The locating plate and the faceplate pressing plate are connected with each other through a plurality of uniformly distributed faceplate connecting bars. The middle of the locating plate and the middle of the faceplate pressing plate are both provided with coaxial locating through holes. Two cutter grooves are formed in the front end of the cutter bar. An inner hole cutter and a plane cutter are installed in the cutter grooves respectively. A plurality of cutter grooves are formed in the rear end of the cutter bar, and a plane cutter is installed in one of the cutter grooves. Compared with the background technology, the faceplate-type tool used for motor base fine turning is adopted, so that the operation of two times of clamping is changed into the operation of one time of clamping and one time of turning without the need for turning round a clamping workpiece or changing the cutter or transforming processes. The coaxiality and end face parallelism degree of a motor base are assured effectively; auxiliary time is shortened effectively, and machining efficiency and benefit are improved greatly.
