Description

Operating device for hydraulic inverting (shift) valve

The utility model relates to a kind of Effector that is used for hydraulic pressure commutation (gearshift) valve.

In known technology, using both at home and abroad the Effector major part of utilizing hydraudynamic drive hydraulic pressure commutation (gearshift) valve to make vehicle advance, retreat, stop with speed change on engineering Transport Machinery vehicle is based on electromagnetically-operated.This electromagnetically-operated device deficiency is that in a single day electromagnet portion goes wrong just makes car load to use, particularly homemade electromagnet often goes wrong, the engineering Transport Machinery vehicle of China's import is because major part is the electromagnetically-operated device at present, every replacing once this device will spend foreign exchange 250 end scholar Francs nearly, therefore cause the car phenomenon of lying prone a lot.

The purpose of this utility model is exactly to overcome the deficiency of known technology and a kind of Effector that is used for hydraulic pressure commutation (gearshift) valve of providing.

The purpose of this utility model realizes by following measure:

Operating mechanism is connected with execution commutation support by the flexible axle that is surrounded by flexible axle skin wire rope.

The structure of operating mechanism provided by the utility model is the anchor plate that being equipped with of cuboid bumped pearl, tightening up seat board on it, little axle is housed on the seat board, being equipped with on the little axle has the location that also is shaped on of circumferential groove to use on the rotating circumferential surface, and with bump the disk that on a side circumferential groove of nest, is shaped on card post blind hole that bumps the pearl nest that pearl is complementary, bump on the disk pearl nest symmetrical beyond solid dead handlebar on the circumference, it is a bit solid extremely in disk card post blind hole with it with the card post to be wound with wire rope in the circumferential groove of disk, the two ends a of wire rope, b is placed in the narrow groove of anchor plate, the flexible axle skin that the wire rope outside is surrounded by is placed in the sipes ditch of anchor plate, the termination withstands on the narrow groove plane, the operating mechanism outside is fixed with protective housing, and stuffing box gland is equipped with at the circular hole place that protective housing passes handlebar.

The joint that is equipped with on the flexible axle skin with the dead admittedly flexible axle b that is connected with operating mechanism of nut on the facade that it is support that the utility model provides first kind of structure of carrying out the commutation support, the termination that wire rope passes nipple orifice extremely is being installed on commutation (gearshift) valve rod admittedly, admittedly extremely on the support facade, rack-mount upper saw pulley is walked around admittedly extremely on pull bar in the termination that wire rope passes nipple orifice in the flexible axle to the joint that is equipped with on the flexible axle skin of the flexible axle a that is connected with operating mechanism with nut.

The joint that is equipped with on the flexible axle skin of dead admittedly the flexible axle a, the b that are connected with operating mechanism of two nuts is housed on the facade that it is support that the utility model provides second kind of structure of carrying out the commutation support, the termination that wire rope passes nipple orifice relatively symmetrically with screw admittedly extremely on reversing plate, reversing plate is fixed on commutation (gearshift) valve rod.

That advantage of the present utility model is is simple in structure, volume is little, in light weight, partly compare with former import fork truck electromagnetically-operated and can alleviate 10 kilograms, saved steel; Be difficult for breaking down, through 20,000 destructive tests, as excellent as before; Operating mechanism is installed under the steering wheel of vehicle, brings convenience to driver operation; This plant area space is little, settles not to be subjected to position limit; Maintenance, installation, debugging are conveniently; Cost is low, the 1/4-1/5 of only suitable electromagnetically-operated device price.

Description of drawings:

Fig. 1 is embodiment's general assembly schematic representation provided by the utility model;

Fig. 2 is Figure 1A-A sectional view;

The another kind of embodiment's that Fig. 3 provides execution commutation supporting structure schematic representation.

In conjunction with the accompanying drawings embodiment provided by the utility model is described in further detail:

First embodiment's structure is made up of three parts, and operating mechanism C is connected with execution commutation support Z by 2 flexible axle a, b that are surrounded by flexible axle skin wire rope.The structure of operating mechanism is that cuboid is equipped with spring and ball are housed in the hole, the oral area reducing prevents the anchor plate that bumps pearl 10 12 that ball falls down, tightening up rectangle seat board 7 with screw 11 on it, little axle 9 is housed on the seat board, on it with check ring 5 block and rotating side face on have circumferential groove also be shaped on three location usefulness and with bump the disk 8 that on a side circumferential groove of nest, is shaped on card post blind hole that bumps the pearl nest that pearl is complementary, bump the pearl nest is equipped with taper knob 1 beyond symmetrical on the circumferential surface with solid dead the end of pin 6 handlebar 2 on the disk, the wire rope 13 usefulness card post 14 that is wound with in the circumferential groove of disk is solid extremely in disk card post blind hole with it, the two ends of wire rope are placed in the narrow groove at anchor plate 33 places, the flexible axle skin 15 that the wire rope outside is surrounded by is placed in the sipes ditch at anchor plate 34 places, thereby the termination withstands on and forms flexible axle a on the narrow groove plane, the two ends of b, operating mechanism is outside with solid dead the protective housing of screw 16, and stuffing box gland 4 is equipped with at the circular hole place that protective housing passes handlebar.The structure of carrying out the commutation support is to consolidate the joint 19 that is equipped with on the flexible axle skin of the dead flexible axle b that is connected with operating mechanism with two nuts 18 on the facade of support 17, wire rope 13 passes the termination of nipple orifice admittedly extremely on the pull bar 21 that is installed on the selector valve 20, also have the joint 23 that is equipped with on the flexible axle skin with the solid dead flexible axle a that is connected with operating mechanism of two nuts 22 on the facade of support 17, wire rope passes joint, and to walk around rack-mount upper saw pulley 24 solid dead on the pull bar that is installed on the selector valve.

The 2nd embodiment's provided by the utility model structure is that operating mechanism C is identical with the 1st embodiment with two flexible pipe a, b, just repeats no more.The structure of carrying out the commutation support is two nuts of two usefulness 26 to be housed on the support facade 25 consolidate the joint 27 that is equipped with on the flexible axle skin of dead the flexible axle a, the b that link to each other with operating mechanism, the termination that wire rope passes nipple orifice is solid extremely on rectangle reversing plate 29 with screw 28 relatively symmetrically, and reversing plate is fixed on the commutation valve rod 31 with key 30 and uses nut 32 that reversing plate is dead admittedly.When reversing plate is swung, thus the oil circuit that just can change selector valve reach vehicle forward and back, stop, action.
