Abstract
A 6-line stretching machine for setting up ultrahigh-voltage transmission lines has 6 active stretch wheels and 6 braking stretch wheels, pair of which are coaxially installed to commmon supporting frame. The conducting lines are drawn out from the stretch wheels by drawing machine and drive the stretch weels to rotate and then the hydraulic motor via chain drive, so generating rotary resistance to stretch wheels for streching the lines. The stretching force can be controlled by regulating the oil pressure at outlet of hydraulic motor. There is a power unit, where high-pressure gear pump supplies hydraulic oil to hydraulic motor and then drives the stretch wheels via chain drive for reverse drawing lines.
Description
The present invention relates to a kind of six stretching machines that are used for the setting up ultra-high-voltage transmission line, it belongs to the construction equipment of ultra-high-tension power transmission line.
In the prior art, 725 type tensioners and the ZD4-30 type tensioner produced of Chinese Shanghai water conservancy project machinery plant for example, and the T50-4AH type tensioner produced of Canadian TE company is one of conductors on quad bundled construction and leads four equipment, these four stretching machines can not set up more transmission lines simultaneously, novel circuit is a compact line, its lead need adopt six splitted construction, be that every phase conductor is made up of six roots of sensation sub-conductor, if use existing equipment construction, can only take unwrapping wire in batches, or the multi-machine collaborative mode, the man power and material consumes very big, inefficiency, and be difficult to ensure the quality of products.
The objective of the invention is, a kind of six stretching machines that are used to set up ultra-high-tension power transmission line are provided, it adopts six lines to divide control to open, the six groups of wire tension wheels that can independently regulate and control are equipped with, can implement the tension stringing operation of 1 to 6 lead simultaneously, both can six line lockings draw, also can do the individual conductors traction, provide simultaneously and can tighten up lead, the same ability of leading that equates with tension force.
Technical scheme of the present invention is: six stretching machines that are used for the setting up ultra-high-voltage transmission line, be provided with the tension force wheels, active tension wheel and braking straining pulley are wherein arranged, each is organized straining pulley and is installed on separately the support, each support is fixed on the chassis of a twin shaft trailer, be respectively equipped with the inlet wire guider in the front-end and back-end on this chassis and go out wire guider, the braking straining pulley has been set up fluid brake, and each is organized the active tension wheel and links to each other with hydraulic motor by chain and sprocket driving device; Also be provided with the power set that comprise diesel engine, high-pressure gear pump and transmission device on this chassis, it links to each other with hydraulic motor and hydraulic oil radiator, hydraulic oil container and fuel tank; On this chassis, also be provided with control cabinet, comprise operation, monitoring, measurement and indicating equipment, the feature of this machine is: described tension force wheels are six groups, comprising six active tension wheels, with six braking straining pulleys, active tension wheel and braking straining pulley all are coaxially installed on the common support in couples; Six active tension wheels link to each other with six hydraulic motors by six cover chain and sprocket driving devices respectively.Advantage of the present invention is:
1, applied widely: because it is provided with the six groups of wire tension wheels that can independently regulate and control, so can
Make the tension stringing operation of opening 1 to 6 lead simultaneously.
2, save lead: can provide with make equate return the ability of leading, therefore recyclable surplus line.
3, regulate steadily, be quick on the draw, have height reliability.
4, operate simple and easyly, be convenient to inspect and keep in repair.
Below with regard to an embodiment and consult accompanying drawing the present invention is elaborated:
Fig. 1 is a structural representation of the present invention
Fig. 2 is a schematic top plan view of the present invention
Fig. 3 is the section of structure of active tension wheel
Fig. 4 is lead winding direction figure
Be illustrated in figure 1 as six stretching machines that are used for the setting up ultra-high-voltage transmission line, oil pump-overflow regulate and control method is adopted in the generation of its tension force and regulation and control.Be provided with six tension force wheels, comprise 1 and six braking of six active tension wheels straining pulley 2, below each braking straining pulley, be provided with hydraulic pressure rim brake gear 3, in order to after shutdown, to check straining pulley 1 and 2, to keep wire tension, each straining pulley is coaxial in pairs to be installed on the common support 4, and three cover supports, 4 spiral shells arranged side by side are contained on the chassis 5 of a twin shaft trailer; Before active tension wheel 1 on the same group was arranged in, driven braking straining pulley 2 was positioned at the rear end of support 4, and attaching has the hinge wheel of chain and sprocket driving device 6 on the active tension wheel 1, is connected with hydraulic motor 7 by chain and sprocket driving device 6.The leading-out terminal of lead 8 links to each other with the hauling machine (not shown).Under the tension force traction working condition, lead 8 is pulled machine and involves from tensioner, drives straining pulley and rotates, and by chain and sprocket driving device 6 driving hydraulic motors 7, this moment, hydraulic motor 7 was pressed the operating mode operation of hydraulic pump, thus straining pulley had been produced steering resistance, made on the lead 8 and had produced tension force; Be in desirable numerical value in order to control tension force, in the outlet of hydraulic motor 7 overflow valve is housed, regulate the tension force of the oil pressure of overflow valve with regard to may command lead 8, hydraulic motor 7 has absorbed mechanical energy from lead 8 through overflow running, make it major part and be converted into heat energy and hydraulic oil is heated up,, need make stream of hot oil through radiator 10 for avoiding the oil temperature too high, cooled hydraulic oil is by the inlet port of the closed oil circuit hydraulic return motor 7 that comprises hydraulic oil container 11, XianCheng's whole circulation; Because of the finite capacity of radiator 10, when using hightension, need suitably to reduce payingoff speed, to guarantee the normal operation of tensioner.
Six stretching machines are provided with hydraulic power unit 9 and hydraulic system thereof, and this device comprises diesel engine, high-pressure gear pump and transmission device thereof, and are furnished with fuel tank 16, and high-pressure gear pump links to each other with hydraulic motor 7.Lead under the operating mode returning, high-pressure gear pump is supplied with hydraulic motor 7 with hydraulic oil, drives by 6 pairs of each active tension wheels 1 of chain and sprocket driving device, thereby lead 8 is oppositely drawn.
As shown in Figure 3: straining pulley 1 and 2 all is installed on the same mandrel 19 in pairs, and be supported on the support 4, on the outer rim of active tension wheel 1, trough of belt offset plate 17 is housed, connect with interlocking latch 18 between two straining pulleys, be provided with a positioning sleeve 20 that is used to install bearing in the outside of mandrel 19, the hinge wheel of a chain and sprocket driving device 6 respectively is housed in two outsides forming right active tension wheel 1.
As shown in Figure 4: inlet wire one end of lead 8 is wrapped on one group of straining pulley 1 and 2 after by inlet wire guider 15, after twining filled band groove offset plate 17, leads to hauling machine through going out wire guider 14.
