[0009]

Embodiments of the present invention will be described below with reference to the drawings.

1 to 3, a guide rail 2 is provided along a wall of a shaft 1 by a plurality of wall connecting members 3. An elevator cage (hereinafter referred to as a cage) 4 is provided on the guide rail 2 so as to be able to move up and down by wheels 4a (FIG. 4), and is moved up and down by a rack 5, a pinion 6 (FIG. 5) and a motor (not shown). I have.

On the other hand, a separate second guide rail 2a is provided on the ground portion so as to be continuous with the guide rail 2, and is entirely raised and lowered by a raising and lowering device indicated by reference numeral 10 as a moving means. I have. In addition, the code | symbol 7 in a figure is a ground entrance, 8 is a basement door, and 9 is a ground call switch.

4 and 5, the undulating device 10 includes:
A base frame 12 fixed to a wellhead base D with anchor bolts 11, and a pin 1 on the side of the wellhead 1 a of the frame 12.
The support frame 14 is pivotally connected via the support frame 3 and connected to the second guide rail 2a by the wall connecting member 3, and a hydraulic cylinder 15 interposed between the two frames 12, 14.

Next, the manner of movement of the cage 4 will be described.

First, the cage 4 is raised and positioned on the second guide rail 2a above the dividing plane C. Then, the user pushes down the switch on the operation panel (not shown). Then, the hydraulic cylinder 15 is contracted, the support frame 14 is rotated clockwise, and the cage 4 is moved from the normal position, that is, from the starting position A to the lying position B. As a result, the opening 1a of the shaft 1 is opened, and the inside of the shaft 1 can be effectively used.

FIG. 6 shows another embodiment of the present invention, in which the moving means is constituted entirely by a turning device indicated by the reference numeral 20. That is, a turning frame 24 is rotatably provided on a base frame 21 fixed to the wellhead foundation D with the anchor bolt 11 via a turning shaft 22 also serving as a floating prevention device and a pair of turning rollers 23. I have. A support frame 25 is erected on the side of the wellhead 1a of the revolving frame 24, and a second guide frame 2a is connected to the support frame 25 by the wall connecting member 3. A hydraulic cylinder 26 is interposed between the turning frame 24 and the base frame 21.

In this embodiment, when the hydraulic cylinder 26 is contracted, the cage 4 is moved through the swivel base 24 to the normal position E.
To the turning position F outside the wellhead 1a.

FIG. 8 shows another embodiment of the present invention, in which the moving means is constituted entirely by a slide device indicated by reference numeral 30. That is, the base frame 31 fixed to the wellhead foundation D with the anchor bolts 11 is provided with a rectangular frame-shaped base 32.
Is erected. Inside the gantry 32, a rectangular frame-shaped support frame 33 includes a pair of upper and lower moving wheels 34,
35 and a slide motor 36 so as to be movable in a direction facing the cage 4. And the support frame 3
A second guide frame 2a is connected to the wellhead 3 via a wall connecting member 3 so as to be able to ascend and descend by a lift L, and is lifted by, for example, 50 mm by a lift device 37.

In this embodiment, after the cage 4 is lifted together with the second guide rail 2a by the lift device 37,
By operating the slide motor 36, the support frame 33 is moved to the side facing the wellhead 1a, and the cage 4 is moved from the normal position G on the wellhead 1a to the moving position H.

[0019]

According to the present invention, as described above, the elevator cage can be moved out of the wellhead to increase the gap of the shaft and the space for carrying in and out the machine.

Therefore, in order to secure a small cross section and a space for carrying in and out of the slip and the machine, it is possible to safely and easily ascend and descend by using an elevator even in a vertical shaft using a monkey ladder or a gondola.
