Dynamic pump is heavier, carries intensity greatly, needs additionally to use air pump additional mechanical supercharging during use, pressure is adjusted repeatedly, causes tensioning thousand
Jin top tensioning speed is slower, and labor strength is big, and often results in that the anchor force of anchor cable is inadequate, supporting quality is poor.
Utility model content
Technical problem to be solved in the utility model is to provide one kind, and can to reduce labor strength, tensioning speed fast
And the anchor cable quick tensioning device of operation.
The utility model solves the technical scheme that its technical problem used：Anchor cable quick tensioning device, including tensioning
Jack, high-pressure rubber pipe, operation valve, feed tube, liquid back pipe, hydraulic pump, the quantity of high-pressure rubber pipe is 2, and stretch-draw jack leads to
Cross high-pressure rubber pipe to be connected with operation valve, high-pressure rubber pipe connects upper operation valve by U-shaped card；Operation valve passes through feed tube and liquid back pipe
It is connected with hydraulic pump；Draining device is respectively arranged with two high-pressure rubber pipes, the draining device includes three-way connection, pressure
Table, stop valve, pressure gauge and stop valve connect three-way connection respectively, and three-way connection is connected with high-pressure rubber pipe by snap joint.
Wherein, in addition to pressure inductor, controller, alarm, pressure inductor is arranged on high-pressure rubber pipe, feeling of stress
Device is answered to be connected with controller, controller is connected with alarm.
It is further that alarm is audible-visual annunciator.
Wherein, a diameter of 10mm of three-way connection, stop valve is diameter 10mm Plane stop valve.
The beneficial effects of the utility model are：There is provided power by hydraulic pump for stretch-draw jack, compared with prior art and
Speech, hydraulic pump is carried more easily, while no longer needing the additional mechanical supercharging equipment such as air pump, reduces the labor intensity of workman；Hydraulic pressure
The pressure that pump is provided can one-time-reach-place, tensioning speed is fast, it is not necessary to adjust repeatedly, easy to operate；On two high-pressure rubber pipes
Draining device is provided with, anchor force can be observed by pressure gauge, output pressure be adjusted by stop valve, it is easy to control, it is to avoid
Draw jack excessively to use, jack pair anchor cable can be made to apply desired pretightning force with accurate stretching force；In addition also set up
There is warning device, alarm can be sent to operating personnel when output pressure is excessive.
Brief description of the drawings
Fig. 1 is the schematic diagram of the utility model one of which embodiment；
Marked in figure：It is stretch-draw jack 1, high-pressure rubber pipe 2, operation valve 3, feed tube 4, liquid back pipe 5, hydraulic pump 6, U-shaped
Card 7, three-way connection 8, pressure gauge 9, stop valve 10, snap joint 11, pressure inductor 12, controller 13, alarm 14.
Embodiment
The utility model is further illustrated below in conjunction with the accompanying drawings.
As shown in figure 1, the utility model anchor cable quick tensioning device, including stretch-draw jack 1, high-pressure rubber pipe 2, operation valve
3rd, feed tube 4, liquid back pipe 5, hydraulic pump 6, the quantity of high-pressure rubber pipe 2 is 2, and stretch-draw jack 1 passes through high-pressure rubber pipe 2 and operation
Valve 3 is connected, and high-pressure rubber pipe 2 connects upper operation valve 3 by U-shaped card 7；Operation valve 3 passes through feed tube 4 and liquid back pipe 5 and hydraulic pump 6
Connection, it is to be understood that feed liquor, return liquid system are formed between operation valve 3 and hydraulic pump 6；Set respectively on two high-pressure rubber pipes 2
Draining device is equipped with, the draining device includes three-way connection 8, pressure gauge 9, stop valve 10, and pressure gauge 9 and stop valve 10 are distinguished
Three-way connection 8 is connected, the control fluid flow of stop valve 10 is so as to avoid stretch-draw jack 1 from excessively using, and pressure gauge 9 is used to observe
Anchorage cable stretching and the degree loosened, three-way connection 8 are connected with high-pressure rubber pipe 2 by snap joint 11.
The mode of operation of above-mentioned technical proposal is that two stop valves 10 are first opened to a quarter respectively to 1/2nd,
Then stretch-draw jack 1 is loaded into anchor cable to be drawn, the slow operation handle for opening operation valve 3, now the feed liquor of feed tube 4, returns liquid
5 times liquid of pipe；The pressure gauge 9 in water influent pipeline is observed simultaneously, when pressure is reached in 24MPa~30MPa, by the operation of operation valve 3
Handle returns zero-bit；Operating personnel holds stretch-draw jack 1, reversely the slow operation handle for opening operation valve 3, while observing back
Pressure gauge 9 on liquid pipeline, when pressure is in 0MPa, removes stretch-draw jack 1, completes anchorage cable stretching process.
