There is a counterweight side guide rail 5 that guides the counterweight 3.

  Next, the hoistway drilling apparatus 20 will be described. First, as a mechanism to be installed on the counterweight, U-shaped steels 6a and 6b that can be attached to counterweights of different sizes by long holes and fixing bolts 7a and 7b are attached to the counterweight 3. Due to the long holes of the U-shaped steels 6a and 6b, the U-shaped steel 8 whose depth direction can be adjusted with respect to the drilling construction part is attached. Brackets 9a and 9b that can be adjusted in the horizontal direction with respect to the drilling portion are attached by the elongated holes of U-shaped steel 8 and bolts 10a and 10b. Drills 11a and 11b are attached to the brackets 9a and 9b, respectively.

  FIG. 2 shows a side view of the hoistway 1 as seen from the side. FIG. 2 is a side view seen from the lower side of FIG. A U-shaped steel 6 is attached to the upper frame of the counterweight 3 using brackets 12 and 13. A cable 15 extends from the drill 11 and a remote controller 16 is attached to the tip. The remote controller 16 includes a “+” button, a “−” button, and a “start drilling” button. The operator operates this button to perform drilling work.

  FIG. 3 shows a detailed view in which the U-shaped steel 6 is attached to the counterweight upper frames 3 a and 3 b of the counterweight 3. FIG. 3 is an enlarged view of part A of FIG. The U-shaped steel 6 is attached to the counterweight upper frames 3a, 3b using the brackets 12, 13 and the holding bolts 14a, 14b and the fixing bolt 7. The bracket 13 is fixed by welding, and the bracket 12 is fixed by a fixing bolt 7. Since the fixing bolt 7 is attached to the elongated hole of the U-shaped steel 6, it can be attached with different widths of the counterweight upper frames a and 3b. Further, by adjusting the fixing bolts 14a and 14b, the fixing bolts 14a and 14b can be attached to the counterweight upper frames 3a and 3b having different heights.

  FIG. 4 shows a detailed view of the drill 11 viewed from the side. FIG. 4 is a view showing a mechanism for pushing out the drill. There is a motor 17 fixed to the car side of the bracket 9. There is a threaded rod 18 that attaches to the motor 17 and rotates as the motor 17 operates. The screw 19 is also cut in the bracket 19 installed on the threaded rod 18, the motor 17 is operated, the threaded rod 18 rotates, and the bracket 19 moves. There is a drill 11 attached to the hole of the bracket 19, and the drill 11 moves together with the bracket 19. A cable 15 is connected to the motor 17 and the drill 11, and a power source and a command are received by the cable 15.

  FIG. 5 shows a view from the B part of FIG. The bracket 19 has a width substantially equal to the inner dimension of the bracket 9 and can move in the depth direction with respect to the drilling portion without turning the bracket 19 even if the threaded rod 18 rotates.

  The “+” button, “−” button, and “drilling start” button of the remote controller 16 will be described. If the “+” button is continuously pressed, the drill 11 is operated, and at the same time, the motor 17 is operated, the threaded rod 18 is rotated, and the drill 11 is moved in a direction approaching the drilling section of the hoistway 1. . If the “−” button is kept pressed, the motor 17 is rotated in the direction opposite to the “+” button, and the drill 11 is moved away from the drilling portion of the hoistway 1. When the “Start Drilling” button is pressed once, the motor 17 and the drill 11 are operated, and after drilling the necessary dimensions for anchor bolt placement automatically, the drill 11 reaches the position before pressing the “Start Drilling” button. Returning, the motor 17 and the drill 11 stop.

  Since the “+” button and the “start drilling” button provided on the remote control 16 have a function of approaching the drilling section of the hoistway 1, the wall surface of the hoistway 1 that is the drilling section has irregularities. Even if it is a drilling construction part of various depths, it is possible to make a drilling operation by pressing the “start drilling” button after making contact with the drilling construction part with the “+” button. In addition, since the “−” button provided on the remote controller 16 has a function of pulling back the drill 11, the function of pulling back the drill 11 after drilling is performed, Obstacles can be avoided.

  FIG. 6 shows the drilling procedure in this embodiment. Work is started in S1. In S2, the counterweight 3 is lowered to the pit. At S 3, the apparatus is attached to the counterweight 3 at the pit portion of the hoistway 1. In S4, the mounting position of the bracket 9 is adjusted by the long hole provided in the U-shaped steel 8 at the horizontal position of the drilling portion. In S5, the counterweight 3 is raised and lowered, and the height of the drilling position is adjusted.

  After S6, a button provided on the remote controller 16 is operated to perform drilling work. In step S6, the "+" button is kept pressed. In step S7, when the contact sound between the drill 11 and the drilling section of the hoistway 1 is heard, the "+" button is released in step S8 to stop the movement of the motor 17 and the drill 11. The drill 11 comes into contact with the construction portion of the hoistway 1 until S8.

  In S9, the “drilling start button” is pressed to drill the dimensions necessary for anchor bolt placement. In S10, it is determined whether or not the construction sound for drilling construction has stopped. When the construction sound has stopped, the "-" button of the remote control 16 is kept pressed in S11 and the drill 11 is pulled back.

  In S12, a place where drilling construction is required in other places is confirmed. If there is a construction place, the process returns to S5, and S5 and subsequent steps are performed. If there are no other drilling locations at S12, the counterweight 3 is lowered to the pit at S13, the device is removed at S14, and the operation is terminated at S15.
