Abstract
The invention discloses a car puller push pawl device. The car puller push pawl device comprises a car puller link plate (1) and a push pawl (3), wherein the push pawl (3) is hinged with the car puller link plate (1) by a joint shaft (2). The car puller push pawl device also comprises a driving gear (6) provided with a collision block (5) and a driven gear (7); the driven gear (7) is hinged with the push pawl (3) by the joint shaft (2); the push pawl (3) is provided with a spacing pin (8) which restraining the unidirectional rotation of the driven gear (7); the driven gear (7) is provided with a chute used for realizing the inverse sliding of the spacing pin (8); and the driving gear (6) and the driven gear (7) are meshed. The car puller push pawl device adopting the technical scheme can operate in a bidirectional way, has simple and compact structure and is safe and reliable after trial.
Description
Technical field
The present invention relates to a kind of rail transportation device, relate in particular to a kind of car puller that mine car advances device of pawling that is used to promote.
Background technology
The tradition car puller device of pawling has the new line formula, promptly pawl upwards lift always by counterweight or extension spring, the go-cart that travels forward of car puller carrier bar, mine car axletree or baffle plate are depressed and are pawled when moving backward, automatically reset by pawling behind mine car axletree or the baffle plate, this kind structure only allows the direction motion of mine car along the go-cart of pawling, and does not allow mine car to drive in the wrong direction.
The another kind of car puller device of pawling is to have touched pawl mechanism by collision block will pawl and lift, device cannot oppositely pass through pawl mechanism but this kind car puller is pawled, if force oppositely to have passed through pawl mechanism, the pawl drive mechanism of device of car puller will be damaged, and cause potential safety hazard.
Summary of the invention
Goal of the invention: the objective of the invention is at the deficiencies in the prior art, the device of can car puller way traffic, safe and reliable pawling is provided.
Technical scheme: in order to realize the foregoing invention purpose, the technical solution adopted in the present invention is:
A kind of car puller device of pawling, comprise the car puller carrier bar and pawl, it is hinged by jointed shaft and car puller carrier bar to pawl, also comprise the driving gear and the driven gear that are provided with collision block, driven gear is by jointed shaft and pawl hinged, pawling is provided with the locating dowel pin of restriction driven gear unidirectional rotation, and driven gear is provided with the chute that is used for the reverse slip of locating dowel pin, driving gear and driven gear engagement.
Described pawl to be provided be used for the extension spring that driven gear resets.
Beneficial effect: the present invention compared with prior art, its beneficial effect is:
1, the car puller device forward travel of pawling, when having touched the rear drive gear rotation of pawl mechanism, the collision block of driving gear drives the driven gear rotation, because it is the obstruction of locating dowel pin drives the perk of pawling, simple in structure, transmission device is flexible, and actv. advances mine car;
2, pawl and be provided with the locating dowel pin of restriction driven gear unidirectional rotation, driven gear is provided with the chute that is used for the reverse slip of locating dowel pin, and the car puller device of pawling drives in the wrong direction, and collision block has touched pawl mechanism, driving gear drives the driven gear rotation, because driven gear is provided with chute, the reverse idle running of driven gear, the original position of pawling is motionless, protected the car puller device of pawling, realize safe driving in the wrong direction, improved the safety factor of this device, and simple in structure;
3, described pawl to be provided be used for the extension spring that driven gear resets, when car puller pawl device when driving in the wrong direction, having passed through pawl mechanism rear drive gear and driven gear sets back under the effect of extension spring at once, because resetting, collision block do not cause the collision block touching when preventing next forward travel, the reliability when further having improved this device operation less than playing a pawl mechanism.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, by a most preferred embodiment, technical solution of the present invention is elaborated, but protection scope of the present invention is not limited to described embodiment.
As shown in the figure, a kind of car puller device of pawling, comprise car puller carrier bar 1, pawl 3, be provided with the driving gear 6 and the driven gear 7 of collision block 5, pawl 3 and driven gear 7 hinged by jointed shaft 2 and car puller carrier bar 1,3 locating dowel pins 8 that are provided with restriction driven gear 7 unidirectional rotation of pawling, driven gear 7 is provided with the chute that is used for locating dowel pin 8 reverse slips, driving gear 6 and driven gear 7 engagements, and described pawling 3 is provided with and is used for the extension spring 9 that driven gear 7 resets.
Principle of work: the car puller device forward travel of pawling, when having touched the rear drive gear rotation of pawl mechanism, the collision block of driving gear drives the driven gear rotation, because it is the obstruction of locating dowel pin drives the perk of pawling, simple in structure, transmission device is flexible, and actv. advances mine car; The car puller device reverse driving of pawling; collision block has touched pawl mechanism; driving gear drives the driven gear rotation; because driven gear is provided with chute; the reverse idle running of driven gear; the original position of pawling is motionless; protected the car puller device of pawling; realized safe driving in the wrong direction; improved the safety factor of this device, and simple in structure, passed through pawl mechanism rear drive gear and driven gear and under the effect of extension spring, set back at once; because resetting, collision block do not cause the collision block touching when preventing next forward travel, the reliability when further having improved this device operation less than playing a pawl mechanism.
Claims (2)
