The double-loop hydraulic system comprises a hydraulic oil tank, an oil pump arranged inside the hydraulic oil tank, and a direction valve and a check valve which are arranged outside the hydraulic oil tank, wherein the oil pump is connected with a motor and the motor drives the oil pump to rotate. The hydraulic oil tank, the direction valve and the check valve are connected through oil pipelines, double oil pipes are arranged inside the hydraulic oil tank to supply oil for the hydraulic system, and the double oil pipes are respectively connected with a pressure gauge. When extraction earth-retaining design is conducted, designing standards do not need to be enhanced, production cost is further lowered, the work period is greatly shortened, and the double-loop hydraulic system is safe and reliable, high in working speed and long in working time.
Description
[technical field]
The utility model relates to the civil works mechanical field, more particularly, relates to a kind of double loop hydraulic system for anchor cable tensioning machine tool.
[background technology]
The used mode of present anchorage cable stretching locking at home all locks with the strength of steel wire retraction.Its personnel's when construction specialty all can't accurately operate, and all very large prestress lose can be arranged, and these unpredictable loss amounts all may make the anchor cable latching force can not reach design standard, and cause unpredictable follow-up accident.
The single hydraulic cylinder jack is used in traditional type stretch-draw mostly, and it is feasible when executing prestressing force during stretch-draw; But in when locking, its lock value is unequal, and is uncontrollable on design load, and prestress lose is all greater than more than 30% of design load, can greatly be affected and causes disaster to occur therefore apply rear lock value.The domestic safety factor that at present this only strengthened when design of foundation pit reduces its offset variable, has so both increased very many costs, very wastes again resource.
[summary of the invention]
The utility model is intended to solve the lock value inequality that prior art exists, and uncontrollable on design load, prestress lose greatly easily causes the problems such as disaster, and a kind of double loop hydraulic system for anchor cable tensioning machine tool is provided.
For achieving the above object, the utility model provides a kind of double loop hydraulic system for anchor cable tensioning machine tool, should be used for the double loop hydraulic system of anchor cable tensioning machine tool by comprising hydraulic oil container, being located at the oil pump in the hydraulic oil container, this oil pump is connected with motor, the driven by motor oil pump rotates, is located at hydraulic oil container outer direction valve and flap valve, be connected by oil pipeline between described hydraulic oil container, direction valve and the flap valve, being provided with double tube in the described hydraulic oil container is the hydraulic system fuel feeding, and this double tube connects respectively a pressure meter.
Described hydraulic oil container top is provided with locking plate and advances control valve.
Contribution of the present utility model is, it efficiently solves the problem that traditional single-cylinder hydraulic system that is used for anchor cable tensioning machine tool exists, and has following beneficial effect:
1 needn't strengthen design standard when doing the design of excavation gear soil, further reduce production costs, greatly the reduction of erection time.
2 is safe and reliable, and operating rate is fast, longevity of service.

[specific embodiment]
As shown in Figure 1 and Figure 2, double loop hydraulic system for anchor cable tensioning machine tool of the present utility model is by comprising hydraulic oil container 1, be located at oil pump 2 in the hydraulic oil container, be located at hydraulic oil container 1 outer direction valve 4 and flap valve 5, described oil pump 2 is connected with motor 3, behind the starter motor 3, motor 3 drives oil pump 2 rotations and is this double loop hydraulic system fuel feeding.
As shown in Figure 1 and Figure 2, be connected by oil pipeline between described hydraulic oil container 1, direction valve 4 and the flap valve 5.Be full of hydraulic oil in the described hydraulic oil container 1, being provided with double tube in the hydraulic oil container 1 is the hydraulic system fuel feeding, and this double tube is divided into No. 1 oil pipe 7 and No. 2 oil pipes 8, and described No. 1 oil pipe 7 connects respectively No. 1 pressure meter 9 and No. 2 pressure meters 10 with the number of being connected oil pipe 8.Described with No. 1 interface (not shown) of No. 1 oil pipe 7 connection hydraulic jack on the hydraulic system, described with No. 2 interface (not shown)s of No. 2 oil pipes 8 connection hydraulic jack on the hydraulic system.
As shown in Figure 1 and Figure 2, described hydraulic oil container 1 top is provided with locking plate and advances control valve 6, is used for advancing the pressure of lockplate.Described hydraulic oil container 1 both sides are provided with handle, are convenient to movable hydraulic fuel tank 1.
As shown in Figure 1 and Figure 2, described direction valve 4 and flap valve 5 are any known direction valve 4 and flap valve 5, and this direction valve 4 is divided into 3 grades, and direction valve 4 is provided with direction valve rod 41, and this direction valve rod 41 can be positioned at any one position such as A1, B1, C1.Described flap valve 5 is provided with two positions, is decompress(ion) position A and stretch-draw position B, and described flap valve 5 is provided with check-valve lever 51, when check-valve lever 51 is positioned at the A position, represents stretch-draw, when check-valve lever 51 is positioned at the B position, represents decompress(ion).
The operating procedure of double loop hydraulic of the present utility model system:
The operation of double loop hydraulic jack:
First lockplate is placed on the ground tackle (ground tackle is loaded onto intermediate plate), hydraulic jack is incorporated on the ground tackle from steel strand, lockplate is placed on the hydraulic jack front end, hydraulic jack is held up to consistent with the bearing plate angle, loading onto post-tensioning moveable anchor and first-class lockplate.
The double loop hydraulic machine operation:
1, first check-valve lever 51 is placed on the B position before the operation;
2, direction valve rod 41 is put and is given the A1 position. the oil pipe of No. 1 pressure meter 9 on the hydraulic press is connected to No. 1 interface of jack. the oil pipe of No. 2 pressure meters 10 on the hydraulic press is connected to No. 2 interfaces of jack;
3, primer fluid press power supply (110V or 220V). the jack piston axle can stretch out, and No. 1 pressure meter 9 can show force value;
