Only because cannot intercommunication using with the hydraulic efficiency installation newly purchased, cause the great wasting of resources. Hydraulic efficiency installation between different brands not can intercommunication use (namely the hydro-pump of homologous series can only arrange in pairs or groups homologous series hydraulic pressure Work tool use). Concrete needs according to power supply enterprise's service work, change the original structure of existing installation, or increase new parts to used equipment, new device, to improve prior art performance and service index. The development multiple hydraulic efficiency installation intercommunication transfer equipment of repacking, is not only a kind of interim measure that is not enough for new installation and that take, and is overcome equipment owning amount outmoded. Can arrange in pairs or groups by flexible utilization the old and new's equipment on the one hand, it is to increase safety coefficient, reduce the Job readiness time, thus allow maintenance troop have more maneuvering ability; The more important thing is that greatly reducing new installation purchases, ensureing to save a large amount of capital inputs under service work safety, the prerequisite that efficiently carries out. Power supply enterprise service technique personnel need a kind of quick, safety, easily device, it is possible to allow existing hydraulic efficiency installation intercommunication collocation use. If using conventional equipment joint, it changes trouble, and working efficiency is low, and maneuvering ability and safety coefficient are lower.
Above-mentioned these are all areas for improvement.
Summary of the invention:
For overcoming the defect of prior art, the purpose of this utility model is to provide a kind of hydraulic efficiency installation X-over, carries out electric power repair, repairing fast for technician.
The utility model technical solution problem adopts following technical scheme:
Hydraulic efficiency installation X-over, comprises male joint and the female joint of hollow structure, and the front end right alignment of described male joint is inserted in the front end of described female joint:
The tightening screw of the hollow that is threaded in the rear end inner chamber of described male joint, the front end inner chamber of male joint is provided with the first spool, it is provided with the first stage clip between described tightening screw and described first spool, the inner chamber of tightening screw, valve core cavity are asphalt channel, are provided with shutoff steel ball between described spool top and the oil outlet of male joint;
The inner chamber of described female joint is coaxially provided with the long spiro nail of valve pocket, valve body and hollow successively, it is connected to the 2nd stage clip in described long spiro nail outer cover, the two ends of described 2nd stage clip are respectively taking the step surface in the big end of long spiro nail and described valve pocket as spring support, and the inner chamber of long spiro nail is asphalt channel;
Radial hole it is provided with in the front end of described female joint, and it is provided with spacing steel ball in described radial hole, front end outer wall in described male joint is provided with a circle groove, and it is connected to adapter sleeve in the outer cover of described female joint, there is between described adapter sleeve inwall and female joint the cavity volume holding described spacing steel ball, between the outer wall and the inwall of adapter sleeve of described female joint, there is relative step surface, and it is provided with return spring in the closed cavity volume formed between two described step surfaces.
Described adapter sleeve has two working positions, and under normality, spacing steel ball described in adapter sleeve shutoff, when return spring stretches, the cavity volume of described adapter sleeve is concordant with the radial hole of described female joint, gives up the throne for holding spacing steel ball.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, outmoded hydraulic efficiency installation good for existing present situation can be made full use of, reduce new installation and purchase, save fixed assets investment.
2, overhaul troop's maneuvering ability to strengthen, select space and collocation mode without expanding under the prerequisite of newly added equipment.
3, the use safety coefficient of hydraulic efficiency installation is significantly improved.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Number in the figure: 1 male joint, 2 female joints, 3 tightening screws, 4 first spools, 5 first stage clips, 6 shutoff steel balls, 7 valve pockets, 8 valve bodies, 9 long spiro nails, 10 the 2nd stage clips, 11 spacing steel balls, 12 grooves, 13 adapter sleeves, 14 cavity volumes, 15 return springs.
Below by way of embodiment, and the utility model is described in further detail by reference to the accompanying drawings.
Embodiment:
Embodiment: composition graphs 1, the hydraulic efficiency installation X-over of the present embodiment, it comprises male joint 1 and the female joint 2 of hollow structure, and the front end right alignment of male joint 1 is inserted in the front end of female joint 2.
The tightening screw 3 of the hollow that is threaded in the rear end inner chamber of male joint, the front end inner chamber of male joint is provided with the first spool 4, the first stage clip 5 it is provided with between tightening screw and the first spool, the inner chamber of tightening screw, valve core cavity are asphalt channel, are provided with shutoff steel ball 6 between spool top and the oil outlet of male joint.
The inner chamber of female joint is coaxially provided with the long spiro nail 9 of valve pocket 7, valve body 8 and hollow successively, it is connected to the 2nd stage clip 10 in long spiro nail outer cover, the two ends of the 2nd stage clip are respectively taking the step surface in the big end of long spiro nail and valve pocket as spring support, and the inner chamber of long spiro nail is asphalt channel.
Radial hole it is provided with in the front end of female joint 2, and it is provided with spacing steel ball 11 in radial hole, front end outer wall in male joint is provided with a circle groove 12, and it is connected to adapter sleeve 13 in the outer cover of female joint 2, there is between adapter sleeve 13 inwall and female joint the cavity volume 14 holding spacing steel ball, between the outer wall and the inwall of adapter sleeve of female joint, there is relative step surface, and it is provided with return spring 15 in the closed cavity volume formed between two step surfaces.
Adapter sleeve 13 has two working positions, and under normality, the spacing steel ball 11 of adapter sleeve shutoff, when return spring stretches, the cavity volume of adapter sleeve 13 is concordant with the radial hole of female joint, gives up the throne for holding spacing steel ball 11.
In using, the rear end of male joint 1 is connected with hydraulic efficiency installation (or hydraulictool) by oil pipe, the rear end of female joint 2 is connected with hydraulictool (or hydraulic efficiency installation) by oil pipe, male joint is docked with the front end of female joint, hydraulic oil channel can be formed rapidly between hydraulic efficiency installation and hydraulictool, when the front end that the front end of male joint 1 is inserted in female joint 2 is inner, a part for spacing steel ball 11 stretches in the groove 12 of male joint periphery, male joint is carried out axial limiting, simultaneously, long spiro nail 9 in female joint supports the shutoff steel ball 6 in male joint, making to form gap between shutoff steel ball and the oil outlet of male joint allows hydraulic efficiency oil pass through. when male joint 1 is extracted by needs in female joint 2, the power overcoming return spring upwards pulls adapter sleeve 13, now the cavity volume 14 of adapter sleeve 13 and the radial hole of female joint are concordant, and spacing steel ball 11 exits from the groove of male joint, can facilitate and easily male joint be extracted in female joint.
