Abstract
The utility model discloses a stop protection device for an operation valve group of a hydraulic support. A limiting locking base plate and a locking rod base plate are fixed on two sides of the operation valve group respectively; a pair of locking grooves are formed in the limiting locking base plate; one end of each of two locking rods is hinged to the locking rod base plate, and the other end of each of the two locking rods is movably clamped into the corresponding locking groove. According to the stop protection device for the operation valve group of the hydraulic support, an operation handle of the hydraulic support can be timely placed at a neutral position (a zero position) and is locked, so that the hydraulic support cannot be falsely operated in any case, and the safety of an operator on a working face is guaranteed. The device is safe, reliable, time-saving and labor-saving, and can be conveniently operated by the operator; the intrinsic safety of the hydraulic support is improved, and the recycling rate reaches 100 percent.
Description
Technical field
The utility model relates to operating valve group resist technology in field, colliery, is specifically related to a kind of hydraulic support operating valve group restraint protective device.
Background technology
The ZF2800/16/24/28 type hydraulic support operating valve that existing fully-mechanized mining working uses designs between two front columns, in convenient operation, also brings certain hidden danger.Hydraulic support operating valve group handle is a lot, and maloperation when false hit or personnel work in personnel are walking about process, easily causes, as: the roof accidents such as wall caving, roof fall, damage staff.Or due to pumping plant maintenance or other reasons, when hydraulic system can not normally be moved, maloperation valve group handgrip, hydraulic support did not have any action at that time, can work as that pumping plant has overhauled or other reasons is processed, can there is misoperation in hydraulic support, this has brought very large hidden danger to production, is easy to the staff of work plane to damage.So need to restraint protective device be installed on hydraulic support operating valve group handle.In the time not carrying out support operation, effectively prevent misoperation.Traditional restraint protective device is too heavy, and in use, pulls moving draw-in groove of two side handle time limits of valve group and easily operating personnel's hand is damaged.
Utility model content
The purpose of this utility model is to provide a kind of device that can quick and precisely locate shaft-like workpiece, thereby operating efficiency can be provided, and reduces operation easier.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of hydraulic support operating valve group restraint protective device, comprise operating valve group and position-limit mechanism, and described position-limit mechanism comprises deadlock lever, limited position stoppage substrate and deadlock lever substrate; On limited position stoppage substrate and deadlock lever substrate, be respectively arranged with installing hole, and be bolted on the both sides of operating valve group; On limited position stoppage substrate, have a pair of locking slot, one end hinge of two deadlock levers is on deadlock lever substrate, and other end activity snaps in locking slot.Described locking slot is the Eight Character trough that two terminal circle bore dia is greater than groove width.The installing hole being positioned on limited position stoppage substrate and deadlock lever substrate is bar shaped installing hole.Facilitate limited position stoppage substrate and deadlock lever substrate to do up-down adjustment, thereby can provide best locked position for two deadlock levers.
Beneficial effect: the utility model both can be used for conventional hydraulic support, can be used for again compound beam cantilever support, and the length of deadlock lever can be according to the length adjustment of the control valve group of hydraulic support.After moving frame or when support overhauls, in time hydraulic support operating handle is placed in to meta (zero-bit) and locking, makes hydraulic support that the phenomenon of support misoperation can not occur in any case again, improved guarantee to work plane staff's safety.This invention adopts simple chain notch, simple in structure, in hydraulic support operating valve group, adopts bolton, and safe and reliable, staff is easy to operate, time saving and energy saving, has improved hydraulic support intrinsic safety, and reclaims reusability up to 100%.
The utility model, for providing safety guarantee the employee of work plane work, makes staff more relieved in the time of work, more feels at ease.Can not cause and cause hydraulic support misoperation, effectively contain that operator in support operating valve group is misoperation phenomenon, the generation of avoid occurring roof fall, leaking top, minimizing personnel drop into, and the input of material, has improved production efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model limiting and protecting device;
Fig. 2 is the Facad structure schematic diagram of limited position stoppage substrate in Fig. 1;
Fig. 3 is the Facad structure schematic diagram of deadlock lever substrate in Fig. 1.
In figure, label 1 is valve group, and 2 is limited position stoppage substrate, and 3 is deadlock lever substrate, and 4 is bolt, and 5 is valve rod, and 6 is deadlock lever, and 7 is bearing pin, and 8 is bearing pin bearing, and 9 is bar shaped installing hole, and 10 is the Eight Character trough.
The specific embodiment
Embodiment 1: a kind of hydraulic support operating valve group restraint protective device, referring to Fig. 1, is respectively arranged with limited position stoppage substrate 2 and deadlock lever substrate 3 in the both sides of valve group 1.On limited position stoppage substrate 2 and deadlock lever substrate 3, be respectively arranged with installing hole, and be fixed on the both sides of operating valve group 1 by bolt 4.
In Fig. 1, on limited position stoppage substrate 2, have a pair of locking slot.In Fig. 2, one end hinge of two deadlock levers 6 is on deadlock lever substrate 3.The other end activity of two deadlock levers snaps in the Eight Character trough 10.When two deadlock levers be installed on the Eight Character trough 10 interior after, can position respectively the valve rod 5 having separated, prevent that each valve rod is struck.
Embodiment 2: referring to Fig. 1, Fig. 2 and Fig. 3, content is substantially the same manner as Example 1, and something in common does not repeat, different: the installing hole being positioned on limited position stoppage substrate 2 and deadlock lever substrate 3 is bar shaped installing hole 9.Facilitate limited position stoppage substrate 2 and deadlock lever substrate 3 to do up-down adjustment, thereby can provide best locked position for two deadlock levers 6.
Claims (3)
1. a hydraulic support operating valve group restraint protective device, comprises operating valve group and position-limit mechanism, it is characterized in that: described position-limit mechanism comprises deadlock lever, limited position stoppage substrate and deadlock lever substrate; On limited position stoppage substrate and deadlock lever substrate, be respectively arranged with installing hole, and be bolted on the both sides of operating valve group; On limited position stoppage substrate, have a pair of locking slot, one end hinge of two deadlock levers is on deadlock lever substrate, and other end activity snaps in locking slot.
2. hydraulic support operating valve group restraint protective device according to claim 1, is characterized in that: described locking slot is the Eight Character trough that two terminal circle bore dia is greater than groove width.
3. hydraulic support operating valve group restraint protective device according to claim 1, is characterized in that: the installing hole being positioned on limited position stoppage substrate and deadlock lever substrate is bar shaped installing hole.
