Abstract
The utility model belongs to the technical field of reduction gear equipment, specifically a prevent misrouting and move reduction gear. Traditional railway hopper car reduction gear has been solved because of not preventing mistake rotating device, and probably lead to bottom door open by mistake to open the discharge, the problem that constitutes a threat to to driving safety, a prevent misrouting and move reduction gear, including the reduction gear, the master jaw, chuck and jack catch, install the chuck on the output shaft of reduction gear, be equipped with a plurality of draw -in grooves on the chuck, install the master jaw on the box of reduction gear, the articulated jack catch that is connected with on the master jaw, the jack catch use the master jaw with the pin joint as the rotatable card of rotation center in the draw -in groove of chuck. This reduction gear has prevents misrouting the dynamic exercise ability, can avoid because maloperation or other factors lead to the unexpected rotation of reduction gear.
Description
Technical field
The utility model belongs to decelerator equipment technical field, specifically a kind of accidental rotation preventing decelerator.
Background technology
The manual mode of traditional bottom door opening-closing mechanism for railroad hopper wagon is to rotate decelerator handwheel by manpower, thereby makes decelerator drive power transmission shaft to rotate. Decelerator itself does not arrange incorrect rotation preventing device, exist because idler or other factors cause decelerator and rotate the possibility that lorry bottom door is opened, and lorry bottom door is as opened or not closing and put in place and will form great threat to traffic safety.
Summary of the invention
The utility model, in order to solve traditional railway hopper wagon decelerator because there is no incorrect rotation preventing device, opens unloading and may cause bottom door to open by mistake, and the problem that traffic safety is constituted a threat to provides a kind of accidental rotation preventing decelerator.
The utility model is taked following technical scheme: a kind of accidental rotation preventing decelerator, comprise decelerator, master jaw, chuck and claw, on the output shaft of decelerator, chuck is installed, chuck is provided with some draw-in grooves, on the casing of decelerator, master jaw is installed, on master jaw, be hingedly connected with claw, claw is stuck in the draw-in groove of chuck as pivot is rotatable with pin joint taking master jaw.
Described chuck hub place is provided with the open circles that can allow reducer output shaft pass, and open circles is provided with the keyway that key can be set, and described chuck is arranged on the power shaft of decelerator by key.
Described master jaw comprises symmetrically arranged two blocks of side plates, between the side plate of both sides, be provided with bearing pin, on bearing pin, be hinged with claw, the side plate of master jaw is provided with corresponding master jaw lockhole, described claw is provided with the claw lockhole corresponding with master jaw lockhole, the head of claw is provided with boss, and boss is provided with pit.
Described claw is installed on master jaw by round pin, and claw can rotate centered by round pin.
When claw being rotated down and being fallen in chuck slot with hand, power shaft is blocked, and whole decelerator cannot rotate again. Because the structural focus of claw is near head, even if Vehicular vibration amplitude is larger, claw can not depart from draw-in groove; Up rotate and leave draw-in groove and be layback state when seize claw head with hand, power shaft is removed locking, and decelerator is free to rotate, and now, because the structural focus of claw is at the head of its layback, claw can not fall in draw-in groove automatically. For ease of seize claw head with hand, be provided with pit in claw head both sides. On claw and master jaw, designed lockhole, claw rotates into after draw-in groove, and the lockhole on claw and master jaw is concentric, now can use lockset to penetrate lockhole and pin claw and master jaw, makes decelerator locking more reliable.
Compared with prior art, the beneficial effects of the utility model are as follows:
1, this decelerator has accidental rotation preventing function, can avoid causing decelerator unintentional rotation due to maloperation or other factors.
2, the ingenious combination of this incorrect rotation preventing device and decelerator, has the features such as simple in structure, reliable in function, easily dismounting, convenience maintenance. This structure can directly apply to existingly to be had on lorry decelerator.

Detailed description of the invention
As shown in Figure 1, 2, a kind of accidental rotation preventing decelerator, comprise decelerator 1, master jaw 3, chuck 4 and claw 5, chuck 4 is installed on the output shaft of decelerator 1, chuck 4 is provided with some draw-in grooves, and master jaw 3 is installed on the casing of decelerator 1, and master jaw 3 is fixed on decelerator 1 casing by screw 2, on master jaw 3, be hingedly connected with claw 5, claw 5 is stuck in the draw-in groove of chuck 4 as pivot is rotatable with pin joint taking master jaw.
Described chuck 4 centers are provided with the open circles that can allow decelerator 1 output shaft pass, and open circles is provided with the keyway that key 7 can be set, and described chuck 4 is arranged on the power shaft of decelerator by key 7.
As shown in Figure 5, described master jaw 3 comprises symmetrically arranged two blocks of side plates, between the side plate of both sides, be provided with bearing pin, on bearing pin, be hinged with claw 5, the side plate of master jaw 3 is provided with corresponding master jaw lockhole 8, described claw 5 is provided with the claw lockhole 9 corresponding with master jaw lockhole 8, and the head of claw 5 is provided with boss, and boss is provided with pit 10.
Described claw 5 is installed on master jaw by round pin 6, and claw 5 can rotate centered by round pin.
As shown in Figure 3, when claw being rotated down and being fallen in chuck slot with hand, power shaft is blocked, and whole decelerator cannot rotate again. Because the structural focus of claw is near head, even if Vehicular vibration amplitude is larger, claw can not depart from draw-in groove. As shown in Figure 4, up rotate and leave draw-in groove and be layback state when seize claw head with hand, power shaft is removed locking, and decelerator is free to rotate, and now, because the structural focus of claw is at the head of its layback, claw can not fall in draw-in groove automatically. For ease of seize claw head with hand, be provided with pit in claw head both sides. On claw and master jaw, designed lockhole, claw rotates into after draw-in groove, and the lockhole on claw and master jaw is concentric, now can use lockset to penetrate lockhole and pin claw and master jaw, makes decelerator locking more reliable.
