Abstract
The utility model discloses a push pawl device of a car puller, which comprises a chain plate (1) of the car puller and a push pawl (3), wherein the push pawl (3) is articulated with the chain plate (1) of the car puller by a hinge shaft (2); the push pawl device of the car puller further comprises a driving gear (6) provided with a touch block (5), and a driven gear (7); the driven gear (7) is articulated with the push pawl (3) by the hinge shaft (2); the push pawl (3) is provided with a limit pin (8) used for limiting the unidirectional rotation of the driven gear (7); the driven gear (7) is provided with a sliding groove used for reverse sliding of the limit pin (8); and the driving gear (6) is meshed with the driven gear (7). By adopting the technical scheme, the push pawl device of the car puller is capable of running along two directions, is simple and compact in structure as well as is safe and reliable through the trial.
Description
Technical field
The utility model relates to a kind of rail transportation device, relates 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 through 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 through 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 through 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 purpose of the utility model is the deficiency to prior art, and 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 scheme that the utility model adopted is:
A kind of car puller device of pawling; Comprise the car puller carrier bar and pawl that hinged through jointed shaft and car puller carrier bar, also comprises the driving gear and the driven gear that are provided with collision block; Driven gear is through 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 utility model 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; Collision block has touched pawl mechanism, and 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, has 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 the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, through a most preferred embodiment, the utility model technical scheme is elaborated, but the protection domain of the utility model is not limited to said embodiment.
As shown in the figure; A kind of car puller device of pawling comprises car puller carrier bar 1, pawls 3, is provided with the driving gear 6 and the driven gear 7 of collision block 5, and it is 3 hinged through jointed shaft 2 and car puller carrier bar 1 with driven gear 7 to pawl; Pawl 3 be provided with restriction driven gear 7 unidirectional rotation locating dowel pin 8; 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 4 rear drive gears 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, and 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; Protect the car puller device of pawling, realized safe driving in the wrong direction, improved the safety factor of this device; And it is simple in structure; Passed through pawl mechanism rear drive gear and driven gear and under the effect of extension spring, set back at once, do not caused the collision block touching less than playing a pawl mechanism because collision block resets when preventing next forward travel, the reliability when further having improved this device operation.
Claims (2)
1. car puller device of pawling; Comprise car puller carrier bar (1) and pawl (3); Pawl (3) hinged through jointed shaft (2) and car puller carrier bar (1); It is characterized in that: also comprise the driving gear (6) and the driven gear (7) that are provided with collision block (5), driven gear (7) is hinged with pawl (3) through jointed shaft (2), and pawl (3) are provided with the locating dowel pin (8) of restriction driven gear (7) unidirectional rotation; Driven gear (7) is provided with the chute that is used for the reverse slip of locating dowel pin (8), driving gear (6) and driven gear (7) engagement.
