Example 1
A manual barring gear of a gearless tractor comprises a pinion 1, a tractor shell 2 and a manual force application mechanism 3 for driving the pinion 1 to rotate, wherein the pinion 1 comprises a pinion body 11 and a connecting shaft 12 penetrating through the central shaft of the pinion body 11, the connecting shaft 12 is rotatably connected to the tractor shell 2, one end of the connecting shaft 12 facing outwards is provided with a connecting hole 121 for detachably sleeving the manual force application mechanism 3 along the extending direction thereof, the manual force application mechanism 3 comprises a connecting rod, the connecting rod penetrates through the connecting hole 121, in order to make the rotation of the manual force applying mechanism 3 drive the rotation of the pinion 1, the connecting hole 121 is usually a prismatic hole, and by using the characteristic of a prismatic column, so that the connecting rod can be smoothly inserted into the connecting hole 121 in the extending direction of the connecting shaft 12, but cannot rotate radially relative to the connecting hole 121, generally, the connecting hole 121 has 3 to 8 ribs; the tractor further comprises a large gear 5 coaxially connected with the tractor rotor 4, and the large gear 5 is meshed with the small gear 1.
Specifically, the engagement of the connecting shaft 12 and the hoisting machine casing 2 is: the traction machine casing 2 is provided with a positioning groove 21 and a positioning hole 22 which are matched with the connecting shaft 12, the positioning groove 21 and the positioning hole 22 are oppositely arranged, the tip of the connecting shaft 12 is matched with the positioning groove 21, the root of the connecting shaft 12 is matched with the positioning hole 22, and the connecting hole 121 is arranged at the root end of the connecting shaft 12.
In a concrete implementation, in order to prevent the large gear 5 and the small gear 1 from being constantly engaged with each other, a spring 13 is abutted between the tip of the connecting shaft 12 and the positioning groove 21 to separate the small gear 1 from the large gear 5 when not in operation, and it should be noted that the small gear 1 has a certain movement space in the axial direction thereof in the hoisting machine casing 2.
In order to ensure that the large gear 5 and the small gear 1 are not aligned when the tractor is used every time, bolt holes are formed in the large gear 5 and the tractor shell to lock the large gear 5 through bolts, and the teeth of the large gear 5 and the teeth of the small gear 1 are staggered when the tractor shell is in a locking state; more optimally, the bolt hole is arc waist hole, adopts above design, can judge pivoted direction through the position of observing the bolt to make operating personnel have sufficient psychological preparation before the operation, avoid taking place beyond the unnecessary.
Specifically, the manual force application mechanism 3 is a hand wheel, and may also include a connecting rod and a force application rod that are perpendicular to each other, the connecting rod is in matching connection with the connecting hole 121, the force application rod is a telescopic rod, when the manual force application mechanism 3 is a hand wheel, it is convenient for an operator to rotate continuously, but compared with the case where the manual force application mechanism 3 includes a connecting rod and a force application rod that are perpendicular to each other, the occupied volume is relatively large, the manufacturing cost is also high, meanwhile, when the second condition is adopted, the force application rod may be a telescopic rod, where the telescopic rod should be understood in a broad sense, the telescopic rod is a telescopic rod as long as the direction is reduced, such as a common sleeve-type telescopic rod, a folding rod (i.e., the force application rod includes two segments that are hinged to the connecting rod, the use condition is that the force application rod is perpendicular to the connecting rod, and the non-working condition, meanwhile, the length of the force application rod can be changed according to different use scene requirements, namely the force arm is changed, and the force application rod is more labor-saving and efficient.
