It is fixed.
The advantages of the utility model：
1st, hydrologic monitoring technology conventional at present stills need substantial amounts of manpower and materials, and operating efficiency is relatively low, the utility model
After fixed pulley system is arranged, substantial amounts of manpower and materials can be saved, while operating efficiency greatly improves.
2nd, improved fixed pulley can effectively solve the friction between conventional communication cable and hydrologic monitoring aperture, avoid operating
During potential safety hazard, while greatly improve the service life of cable.
3rd, on the one hand the support on fixed pulley top can be used as carrying handle, and on the one hand the cable of afterbody can be entered
Row locking, cable is fixed on support by can so during gathered data does not continue Dragging Line so as to just have to manpower
Cable.
4th, improved fixed pulley is not merely applied to the hydrologic monitoring hole of a certain determination bore, can pass through adjustable pulley two
Distance of the side hydraulic support away from center, suitable for the measurement of different bores；Hydraulic means can be expired by adjusting lifting simultaneously
The different height of sufficient hydrologic monitoring pitch-row from the ground.

Embodiment
As shown in Figure 1-Figure 3, a kind of fixed pulley structure, including a pair of symmetrically arranged hydraulic jacks 6, two hydraulic jacks
The lifting pin on top 6 is vertically arranged respectively, and the bottom of two hydraulic jacks 6 is connected to horizontal base 8, and each base 8 divides
It is not fixed on ground, the horizontal pulley center shaft member 5 of central shaft is supported by between the lifting pin upper end of two hydraulic jacks 6,
Concentrically axle is rotatablely equipped with pulley 4 in pulley center shaft member 5, and the metal across pulley 4 is also associated with pulley center shaft member 5
Support 3, coiling stake 1 is connected with vertically on metallic support 3.
Each base 8 is respectively equipped with multiple base fixing holes, and each base 8 is respectively by through base fixing hole
Anchor studs are fixed on ground.
Each lifting pin upper end is connected to annulus buckle 9, and concentrically axle is assemblied in two annulus cards to pulley center shaft member 5
On button 9.
Cable locking device 2 is also associated with metallic support 3, cable locking device 2 is included perpendicular to pulley center shaft member 5
A pair of vertical metal splint 2-2 are slidably fitted with central axial slide rail 2-4, slide rail 2-4,2-2 hangs down in two metal splints
Direct puncture has crossed at least two screw 2-1, and each screw 2-1 is locked by nut 2-3 and metal splint 2-2 respectively.
The utility model mainly includes 3 parts：1) fixed pulley support：Including coiling stake, cable locking device；2) it is fixed
Pulley, center shaft member；3) hydraulic lift：Annulus buckle etc..Specifically include the following steps：
