The utility model provides an in case the quick change device of current engineering machine tool have the handle of maloperation pilot valve, the accessory dangerous problem that drops will appear.
Description
Technical field
This utility model relates to technical field of engineering machinery, the stopping means of a kind of pilot valve handle for engineering truck.
Background technology
Pilot valve is a kind of control valve controlling banked direction control valves (distributing valve) valve rod action, it is achieved the action of hydraulic jack on the action of equipment and accessory, fast replacing device.It is equipped with the engineering machinery of fast replacing device, only needs driver to handle pilot valve handle in driver's cabin, just can complete the fast assembling-disassembling of equipment.As shown in Figure 1, the fast replacing device of existing engineering machinery includes pilot valve 1, distributing valve 4, hydraulic jack 5, bearing pin 6, pilot valve 1, distributing valve 4, hydraulic jack 5 are connected by fluid pressure line 3, bearing pin 6 is installed on the outfan of hydraulic jack 5, accessory is connected fixing by bearing pin 6 with quick-change frame, during use, handles pilot valve handle 2, control the flexible of corresponding hydraulic jack 5 by distributing valve 4 and promote bearing pin 6 action, it is achieved accessory and the connection of quick-change frame and disconnection.This fast replacing device can easily realize scraper bowl, chain stay, embrace the replacing of the accessories such as fork, arm, and accessory is once locked, and must not operate the handle of the pilot valve of control fast replacing device, otherwise there will be accessory and drops and cause danger.At present, market there is not limiting the device of the action of pilot valve handle.
Utility model content
The purpose of this utility model is to provide a kind of pilot valve handle stopping means, and this device can solve the fast replacing device of existing engineering machinery and there is the handle of once maloperation pilot valve, arises that accessory drops the problem of danger.
In order to solve the problems referred to above, the technical solution adopted in the utility model is: this pilot valve handle stopping means includes that bearing and limiting plate, described limiting plate are provided with the bayonet socket of clamping pilot valve handle, and described limiting plate is connected with described bearing by locking member.
In the technical scheme of above-mentioned pilot valve handle stopping means, more specifically technical scheme is it may also is that described limiting plate is provided with elongated hole, and described locking member includes that the clamping screw through described elongated hole, described clamping screw are threadeded with described bearing.
Further, the afterbody of described clamping screw is provided with the jack inserting bayonet lock.
Further, described bearing includes support and for supporting the gripper shoe of described limiting plate, and described gripper shoe is connected with described support by connector, and described gripper shoe is provided with the screwed hole connecting described clamping screw.
Further, described support offers the stopper slot being slidably matched with described limiting plate.
Further, described support has base plate, and the two ends of described base plate are provided with mounting groove.
Owing to have employed technique scheme, this utility model compared with prior art has the advantages that
1, bearing and the limiting plate with bayonet socket are set, the action of pilot valve handle can be limited, it is to avoid maloperation, cause accessory to drop；Locking member is set；I.e. lockable limiting plate, again can be when needs Quick universal, and Rapid reversal locks, and handles pilot valve handle.
2, limiting plate arranges elongated hole, and locking member uses the clamping screw through elongated hole, only needs sliding skateboard manual latch assembly that slide plate is fixed on T-shaped and props up and take, can easily realize the locking of pilot valve handlebar during locking, and it is simple to operate, convenient.
3, clamping screw afterbody sets jack and inserts bayonet lock, limits clamping screw and gets loose, and reliability is high.
4, support base plate two ends set mounting groove, bearing can be made to share one group of installation screw with the installing hole of pilot valve, install simple.

Detailed description of the invention
The utility model is described in further detail for embodiment below in conjunction with the accompanying drawings:
Pilot valve handle stopping means shown in Fig. 2 mainly includes that bearing 7, limiting plate 8 and locking member 9, limiting plate 8 are connected with bearing 7 by locking member 9.As it is shown on figure 3, bearing 7 includes support 7-1 and gripper shoe 7-2, gripper shoe 7-2 is used for support limit plate 8, and gripper shoe 7-2 is fixed on support 7-1 top by screw 7-3；Support 7-1 has an a base plate 7-11 and riser 7-12, riser 7-12 is perpendicular with base plate 7-11, the upper end of riser 7-12 has a stopper slot 7-14, this stopper slot 7-14 is used for placing limiting plate 8, limiting plate 8 is slidably matched with stopper slot 7-14, and the bottom of riser 7-12 is connected to, in the middle part of base plate 7-11, be provided with mounting groove 7-13 at the two ends of base plate 7-11, the position of mounting groove 7-13 is corresponding with pilot valve installing hole, so that bearing 7 and pilot valve 1 share one group installs screw.As shown in Figure 4, one end of limiting plate 8 offers the bayonet socket 8-1 matched with pilot valve handle 2, and limiting plate 8 also has an elongated hole 8-2, and locking member is connected through this elongated hole 8-2 with bearing 7, sees Fig. 2.Locking member shown in Fig. 5 includes that clamping screw 9-1 and bayonet lock 9-2, clamping screw 9-1 have Handheld Division 9-11 and screw rod 9-12, and the afterbody at screw rod 9-12 has the jack for grafting bayonet lock 9-2.
As shown in Figure 6, during installation, bearing 7 is arranged on the mounting platform 1-1 of pilot valve 1, limiting plate 8 loads in the stopper slot 7-14 of support 7, make its bayonet socket 8-1 towards pilot valve handle 2, gripper shoe 7-2 of bearing 7 and limiting plate 8 have the part contact of elongated hole 8-2 simultaneously, are then passed by clamping screw 9-1 in the screwed hole 7-21 of elongated hole 8-2 screw-in gripper shoe 7-2 of limiting plate 8.
This pilot valve handle stopping means utilizes machinery to realize the spacing of pilot valve handle 2, its simple in construction, and reliability is high, and easily operated.During operation, according to the position slip limiting plate 8 of pilot valve handle 2, block pilot valve handle 2 with the bayonet socket 8-1 of limiting plate 8, then tighten clamping screw 9-1, limiting plate 8 is connected with gripper shoe 7-2 fixing, thus limits the action of pilot valve handle 2.After having assembled, the jack that bayonet lock 9-2 is inserted clamping screw 9-1, then bayonet lock 9-2 afterbody is pulled open, to prevent set and locking screw 9-1 from getting loose.
