The mounting seat can be provided with a plurality of monitoring instruments at the same time, so that the rest of bracket structures can be saved, and the brackets of all the detection instruments are integrated together (at ordinary times, different instruments are required to be arranged at different heights, so that the brackets cannot be shared, but in the invention, the height is adjustable, so that the bracket integration can be performed). In addition, when the monitoring instrument at the high position is required to be maintained and replaced, the mounting seat and the monitoring instrument can be moved downwards to the vicinity of the ground together, and the monitoring instrument does not need to be climbed to the high position to be maintained and replaced as in the prior art.
When high-altitude maintenance is needed (for example, the first electric winch needs maintenance), or when high-altitude numerical reading is needed, an operator can stand in the hanging basket, and then the hanging basket is driven to the needed height by the second electric winch.
It should be noted that the electric hoist with self-locking function belongs to the prior art, and the self-locking mode can be various conventional self-locking modes such as worm gear self-locking, electric control self-locking and the like. The monitoring instrument needs to have a data recording function, or is connected with a display device, a controller and the like on the ground in a data connection and a signal connection (preferably without wireless signal connection, or can be connected by a data wire, and the data wire needs to reserve a length allowance and can adapt to the position and the height change of the monitoring instrument).

The starting cavity is arranged between the front-end rotating wheel and the starting oil cavity, the protecting cavity is arranged between the movable friction block and the protecting oil cavity, the protecting cylinder body is arranged below the movable friction block, the winch rope passes through the upper part of the axis of the front-end rotating wheel, the winch rope passes through the lower part of the axis of the middle rotating wheel, and the winch rope passes through the upper part of the axis of the terminal rotating wheel;
in the vertical direction: the second electric winding drum is positioned between the front end rotating wheel and the middle rotating wheel, and the middle rotating wheel is positioned between the second electric winding drum and the terminal rotating wheel;

When the hanging basket is at a lower position, the hanging basket can directly fall on the elastic protection pad even if the second electric hoist fails in self-locking and the second sliding block slides down, so that operators in the hanging basket can be protected. When the hanging basket is at a higher position, the protection effect of the elastic protection pad is weak. While in this embodiment another form of effective protection is provided.
Taking the perspective of figures 4-7 as an example,
when the self-locking of the second electric hoist fails, the free end of the second winding lifting rope begins to fall rapidly, and the rotation speeds of the second electric winding drum, the front end rotating wheel, the middle rotating wheel and the terminal rotating wheel are all increased (at least far greater than the normal maximum rotation speed at ordinary times). Because the front end rotating wheel suddenly becomes very large, the broach spring is stretched very long under the action of a large centrifugal force, the cutting edge of the cutting knife leaves the cutting groove (when normal rotation is carried out at ordinary times, the rotating speed is not very large, the centrifugal force is not very large, the cutting edge of the cutting knife does not leave the cutting groove), the front end rotating wheel is contacted with the hoisting rope to bypass the part of the front end rotating wheel, the part is cut (the hoisting rope can not be directly cut off, because the large centrifugal force and the very sharp cutting edge are needed, the function can be realized only by requiring the effect of cutting a rope), a thin point appears on the second winding rope, then the fixed end gravity cannot be borne, the thin point is broken, the left pulling force (from the second winding rope) originally born by the front end rotating wheel is eliminated, the starting spring drives the front end wheel frame to move right, the transverse piston rod and the starting piston move right, hydraulic oil in the starting oil cavity flows into the protecting piston, the vertical and the friction block move up, the friction protecting piston rod passes through the friction protecting gap (the friction block and the second winding rope) and the friction block is tightly pressed down to the piston rod and the piston rod is finally pressed down along with the friction protecting block. If the second hoisting rope is tightly pressed by the fixed friction block and the movable friction block, the hanging basket connected with the fixed end does not fall on the elastic protection pad yet, so that the ground contact collision can not occur; if the second hoisting rope is tightly pressed by the fixed friction block and the movable friction block, the hanging basket falls onto the elastic protection pad, and the second hoisting rope is pressed by the fixed friction block and the movable friction block to continuously reduce the speed in the early stage, so that the speed is not high at the moment that the hanging basket falls onto the elastic protection pad, and operators in the hanging basket can be effectively protected. It should be noted that the front end runner, the middle runner and the terminal runner are designed to make the length of the vertical delay section and the transverse delay section of the second winding lifting rope long enough, so that after the second winding lifting rope breaks, before the fixed friction block and the movable friction block press the second winding lifting rope, the second winding lifting rope can always pass through between the fixed friction block and the movable friction block (otherwise, the friction speed reduction and final clamping functions cannot be realized without the second winding lifting rope always passing between the friction block and the movable friction block).
