Abstract
The utility model provides a protection device for the cage of the shaft well, wherein, each side of the cage and a tension weight near the shaft well is provided with a convex block; the two sides of the shaft well are respectively provided with a work positioning switch and an overwinding positioning switch; and the work positioning switch and the overwinding positioning switch are respectively provided with a switch contact that can rotate upward and downward. When the switch contact rotates downward, the switches are connected; when the switch contact rotates upward, the switches are disconnected. The utility model has characteristics of simple structure and convenient using.
Description
Technical field:
The utility model relates to a kind of vertical shaft cage fender guard.
Background technology:
When existing vertical shaft cage promotes operation, hoister is observed the position at cage place by pointer displayed position on the depth indicator, this fully by people's control, when driver attention was not concentrated or be sleeping, it is inaccurate that the cage stop position more easily takes place.Even be raised to and when not having the space slippery fellow drawn badly, steel rope is broken, and accident causes casualties.
Summary of the invention:
The purpose of this utility model just provides a kind of vertical shaft cage fender guard, and this device can stop to rise or descending when cage is elevated to certain altitude or when dropping to a certain degree automatically.
The purpose of this utility model can realize by following scheme.
Lean on a side of vertical shaft to be provided with a projection at cage and bob-weight, respectively be provided with work limit switch and two switches of pulleying limit switch in the both sides of vertical shaft, described work limit switch and pulleying limit switch are provided with a switch contact that can rotate up and down, switch connection when switch contact down rotates, switch disconnects when it up rotates.
Principle of work of the present utility model is, when cage rose to certain altitude, the switch contact that the projection of cage side can touch the work limit switch upwards rotated it, and work limit switch cut off sends control command, makes winch orderly shutdown band-type brake; When cage surpasses the work limit switch, the switch contact that projection backs down the pulleying limit switch once more makes the gig sudden stop, when cage drops to wellbore bottom, then utilize projection on the bob-weight to the work limit switch and the pulleying limit switch on the vertical shaft left side, touch and make cage to stop to descend.The utlity model has characteristics such as simple in structure, easy to use.
Description of drawings:
Fig. 1, the utility model structural representation
The specific embodiment:
Contrast Fig. 1 as can be known, lean on a side of vertical shaft 3 to be provided with a projection 4 at cage 1 and bob-weight 2, respectively be provided with work limit switch 5 and 6 two switches of pulleying limit switch in the both sides of vertical shaft 3, described work limit switch 5 and pulleying limit switch 6 are provided with a switch contact that can rotate up and down 7, switch connection when switch contact 7 down rotates, switch disconnects when it up rotates.
