The specific embodiment
Embodiment one: referring to Fig. 1~Fig. 4, and Fig. 6.Hydraulic support hydraulic pressure valve group protector of the present invention; Comprise two locking fixed heads 1; Two deadlock levers 2, center latching mechanism, said protector is fixedly installed togather through two locking fixed heads 1 and connecting bolt and hydraulic valve bank; Said two deadlock lever 2 two ends are hinged with two locking fixed heads 1 respectively; The same side of two deadlock levers 2 respectively is provided with a locking pin-and-hole 4, and said center latching mechanism is made up of 5 and two lockweights 3 of an eccentric locking wheel, and said eccentric locking wheel 5 is hingedly fixed in the lateral surface of one of them locking fixed head; Two lockweight 3 activities are fixed on the lateral surface of this locking fixed head; Said eccentric locking wheel is connected with two lockweights, and it is corresponding with locking pin-and-hole 4 on the deadlock lever 2 that two lockweights 3 pass the locking fixed head at place respectively, realizes and the interlocking of deadlock lever through eccentric locking wheel.
Embodiment two: referring to Fig. 1~Fig. 4, and Fig. 6, Fig. 5.The hydraulic support hydraulic pressure valve group protector of present embodiment; Different with embodiment one is; Center latching mechanism is as shown in Figure 5, also comprises locking guide 3-1 and locking adapter sleeve 3-2 and locking adapter sleeve connecting rod 3-3, in the locking guide 3-1 that packs into after the suit lockweight back-moving spring (not shown) on the lockweight 3; Locking guide 3-1 and locking fixed head are fixedly connected; Locking adapter sleeve 3-2 is arranged on outside the locking guide 3-1, respectively is provided with a circular pin hole on said lockweight, the locking adapter sleeve, and said lockweight puts and is provided with a rectangle pin-and-hole; Corresponding back, position, three pin-and-hole holes on lockweight, locking guide, the locking adapter sleeve connects (seeing Fig. 5 and Fig. 2) through connecting pin 3-4; Two locking adapter sleeves link together through locking adapter sleeve connecting rod 3-3, and the eccentric locking wheel 5 that is connected with operating grip is hingedly mounted on this side locking fixed head 1, eccentric locking wheel 5 and the interlock of locking adapter sleeve connecting rod 3-3 coupling.Two lockweights can be in locking guide 3-1 under the drive of locking adapter sleeve connecting rod 3-3 and locking adapter sleeve 3-2 and lockweight back-moving spring move left and right, thereby realize the locking and the release of lockweight 3 and deadlock lever 2.
Described hydraulic support hydraulic pressure valve group protector, locking guide one end is provided with corresponding external screw thread or the Connection Block structure is connected with the locking fixed head, on said locking fixed head, is provided with the internal thread hole with said external screw thread or Connection Block fastening screw coupling.The locking fixed head of setting-up eccentricity blocking mechanism is provided with two engaging lugs, and the eccentric locking wheel of said center latching mechanism is hingedly mounted on two engaging lugs through connecting bolt.
Hydraulic support hydraulic pressure valve group protector of the present invention, the composition step of each element is following:
1, with connecting bolt eccentric locking wheel is installed on two engaging lugs of locking fixed head;
2, put lockweight on the locking fixed connecting plate, spring is contained on the lockweight, lockweight is packed in the locking guide;
3, with locking adapter sleeve connecting rod two locking adapter sleeves are connected together, be sleeved on two lockweights and put;
4, the position, hole on adjustment lockweight, locking guide, locking adapter sleeve to three element is corresponding, puts on connecting pin, makes lockweight and locking adapter sleeve composition one, lockweight can be in the locking guide under the drive of locking adapter sleeve move left and right.
The processing and fabricating of hydraulic support hydraulic pressure valve group protector of the present invention requires:
After these blocking device Installation and Debugging, should reach:
When free state, 1, the peak excursion point of locking wheel crosses horizontal level, under the center latching mechanism tension, keeps inactive state, the lockweight end stretches out the length of locking fixed head must not be greater than 1.5 millimeters; 2, deadlock lever can around be connected in locking fixedly bearing pin and the loosening connecting bolt on the plate hole rotate flexibly.
When blocking, 1, the lockweight end stretches out about 8 millimeters of the length of locking fixed head, and reliably insert in the obturator hernia of deadlock lever; 2, deadlock lever fixedly under the acting in conjunction of the bearing pin on the plate hole, loosening connecting bolt and lockweight, is in locking state in locking.
Operating principle:
Blocking function is realized: the locking connecting rod is gone to and hydraulic valve bank operating grip both sides; Get to and operate valve handle parallel position to eccentric locking wheel handle; At this moment locking adapter sleeve connecting rod is nearest apart from the position of eccentric wheel rotating shaft; Under the effect of spring tension, lockweight and locking adapter sleeve are towards the side shifting near fixed head, and lockweight passes and inserts from the locking pin-and-hole of fixed connecting plate in the corresponding obturator hernia of deadlock lever; Deadlock lever is pinned, and assurance hydraulic valve bank operating grip is failure to actuate under external force.
Unlocking function is realized: get to and operate valve handle upright position to eccentric locking wheel handle; Lockweight and locking adapter sleeve along with locking adapter sleeve connecting rod towards a side shifting away from fixed head, at this moment eccentric locking wheel peak excursion point is crossed connecting rod, under the spring force effect; Eccentric wheel, eccentric wheel handle and locking adapter sleeve connecting rod are interlocked; Keep inactive state, locking adapter sleeve connecting rod increases apart from the position of eccentric wheel rotating shaft, and lockweight withdraws from from the locking pin-and-hole of fixed connecting plate; The deadlock lever unlocking, the support operative employee can control hydraulic valve bank according to need of work.
