Description

Planet carrier multi-claw hanger

Technical Field

The utility model relates to a hoist especially relates to a planet carrier multi-claw hoist.

Background

The planet carrier is an output component of the transmission device, has the advantages of small volume, large transmission ratio, strong bearing capacity and the like, bears all torque output in the planetary reducer and is an important component of the planetary reducer, so the quality of the planet carrier influences the working performance of the machine.

The lifting appliance of the planet carrier commonly adopted in the prior art is a lifting rope and an iron chain, and because the two types of lifting appliances are flexible structures, the condition that the axis is vertical and the end surface is horizontal in the lifting, translating and side turning processes of the planet carrier cannot be guaranteed, so that a workpiece is easy to collide with the ground in the putting-down process, the quality cannot be guaranteed, especially when a vehicle is loaded, the planet carrier is a cylinder and requires the end surface to be leveled, otherwise, the planet carrier can roll everywhere, and the loading time is prolonged. Chinese patent with publication number CN203529720U discloses a planet carrier mounting and rotating adjustment mechanism for a planetary reducer, which comprises a circular connecting plate, wherein a first lifting lug is fixed at the center of the upper surface of the connecting plate, three first lifting hooks are uniformly arranged on the circumference of the lower surface of the connecting plate, which uses the first lifting lug as the center of a circle, a second lifting lug is hung on each first lifting hook, the lower end of each second lifting lug is connected to a connecting nut, and the lower end of each connecting nut is in threaded connection with a second lifting hook. The height of the lifting lugs is adjusted to adjust the height of the planet carrier when the planet carrier is lifted; the planet carrier can be conveniently and quickly installed into the shell by using the hoisting mechanism, but still needs to be manually adjusted.

SUMMERY OF THE UTILITY MODEL

To the above-mentioned prior art defect, the utility model discloses a task lies in providing a planet carrier multitooth hoist, solves the steady hoist and mount problem of planet carrier.

The utility model discloses technical scheme is such: the utility model provides a planet carrier multi-jaw hoist, includes rings, jib, hanging wall, hook and lower wall, rings connect in the top of jib, the lower wall with the bottom fixed connection of jib, the hanging wall suit in on the jib and with jib is at vertical direction sliding fit, the hook is equipped with and is no less than three, the hook with the hanging wall is articulated and is in the circumferencial direction equipartition of hanging wall, the hook with the outer border contact of lower wall, the distance of the pin joint to the upper wall center of hook and hanging wall is less than the contact point to the lower wall center distance of hook and lower wall, the hanging wall center with the coaxial setting in lower wall center.

Further, the distance from the contact point of each claw and the lower disc to the center of the lower disc is equal, and the distance from the hinge point of each claw and the upper disc to the center of the upper disc is equal.

Furthermore, the hook claw is hinged to the edge of the upper disc through a pin shaft.

Preferably, the number of the hooks is three.

Furthermore, the claw is in an L shape with the bottom bent outwards.

Furthermore, the side edge of the lower disc is provided with sliding grooves which are the same in number as the hook claws, and the hook claws are in sliding fit with the sliding grooves.

The planet carrier multi-claw hanger is used for lifting a planet carrier by utilizing the contact of the claw and a blank surface which is not processed by the opening aiming at the structural characteristics (a rotary body and the radially and uniformly distributed opening) of the planet carrier. Compared with the prior art, the utility model the advantage lie in: (1) the hoisting process is stable: by utilizing the characteristics of the planet carrier revolving body, the axis of the planet carrier is automatically aligned by the inner support of the lifting appliance, and the lifting, putting down and translation processes are stable. (2) Reducing collision deformation: because the stable characteristics of this hoist and mount, the axis of planet carrier can keep vertical to the terminal surface keeps the level with ground, when putting down, and the terminal surface contacts with ground, has increased the contact surface area, has reduced the emergence that sharp arris and excircle head spline collided with.

Detailed Description

The present invention will be further described with reference to the following examples, which should not be construed as limiting the invention.

Referring to fig. 1, 2 and 3, the planet carrier multi-jaw hanger according to the present embodiment includes a hanging ring 1, a hanging rod 3, an upper plate 4, a hook 5 and a lower plate 6, wherein the hanging ring 1 is connected to the top end of the hanging rod 3 through a connecting sleeve 2. The lower disc 6 is disc-shaped and is fixedly connected with the bottom end of the suspender 3. The embodiment is a three-jaw hanger, the upper disc 4 is in a three-tooth shape, the convex tooth-shaped edge of the upper disc is hinged with the top of the bent L-shaped hook claw 5, and the upper disc and the bent L-shaped hook claw are connected through a spring gasket and a bolt 8. The hook claw 5 is positioned at the trisection position of the circumference of the upper disc 4, the center of the upper disc 4 is provided with a through hole, and the upper disc 4 is sleeved on the suspension rod 3 and is in sliding fit with the suspension rod 3 in the vertical direction. The hook claw 5 is contacted with the outer edge of the lower disc 6, and the bottom of the hook claw 5 is bent outwards towards the circumference. The distance from the hinged point of the claw 5 and the upper disc 4 to the center of the upper disc is less than the distance from the contact point of the claw 5 and the lower disc 6 to the center of the lower disc. The distances from the contact points of the hooks 5 and the lower disc 6 to the center of the lower disc are equal, the distances from the hinged points of the hooks 5 and the upper disc 4 to the center of the upper disc are equal, and the center of the upper disc and the center of the lower disc are coaxially arranged. As an optimized structure, the side edge of the lower disc 6 can be provided with sliding grooves with the same number as the hook claws 5, and the hook claws 5 are in sliding fit with the sliding grooves.

The use process of the device is that the three-jaw lifting appliance is placed in the central hole of the planet carrier 8, and the travelling crane lifts the lifting ring 1 of the three-jaw lifting appliance, so that the lower disc 6 is lifted to drive the three hook claws 5 to hook the planet carrier 8, and the planet carrier 8 is lifted or lowered. The working principle of the hanger is that upward forces borne by the hanger rod 3 and the lower disc 6 are transmitted to the three hooks 5, the forces borne by the three hooks 5 are equal in magnitude and outward from the axis in the direction, and the resultant force of the forces and the self weight of the planet carrier 8 keep balance, so that the planet carrier 8 keeps balance in the hoisting process.
