Detailed Description

The following detailed description of the present invention is provided in connection with the accompanying drawings and the embodiments, and is not intended to limit the scope of the invention.

As shown in fig. 1, the lifting appliance for the self-displacement of the front axle of the embodiment comprises an underframe 1 capable of being inserted into a front axle fabrication hole and a hanger 2 forming a ═ shape with the underframe 1, wherein the underframe 1 is provided with a locking mechanism 3 for preventing the front axle from sliding off; locking mechanism 3 includes round bar 31, round bar 31 runs through chassis 1 and relative chassis 1 is rotatable and slides, the one end of round bar 31 is fixed with end plate 32 and is located chassis 1 inserts the outside of end, the other end of round bar 31 is fixed with turns round board 33 and is located chassis 1 lifts by crane the outside of end, round bar 31 is fixed with jam plate 34 and is located chassis 1 insert the end and lift by crane the centre of end. Specifically, the hanger rods 21 of the hanger 2 are fixed at one end of the underframe 1, the end is a lifting end, an included angle between each hanger rod 21 and the underframe 1 is 45-90 degrees, the number of the hanger rods 21 is two, pin shafts 22 penetrate through the tops of the two hanger rods 21, two ends of each pin shaft 22 are locked through nuts, and the pin shafts 22 are rotatably connected with horseshoe-shaped hanging rings 23.

The utility model is mainly used for turning over the front axle with the fabrication hole and also can be used for turning over other workpieces with holes, during operation, the bottom frame 1 suspended on the lifting rope is inserted into the fabrication hole of the front axle, then the twist plate 33 is rotated to 90 degrees, so that the locking plate 34 stands up, and the height of the standing locking plate 34 is greater than the width of the fabrication hole of the front axle, thereby preventing the front axle from sliding off from the bottom frame 1 during lifting; in order to better lock the front axle, the locking plate 34 is designed in a trapezoidal shape, when in lifting, the shorter end of the bottom edge of the locking plate 34 is inserted into the front axle fabrication hole in a wedge shape, and at the moment, the front axle is locked by the cross and cannot move relative to the underframe 1. If the underframe 1 is inserted into the front axle fabrication hole, the hanger 2 is arranged on the upper portion, when the front axle is lifted, the front axle can automatically turn over by 30-60 degrees under the action of gravity, and then when the front axle falls down, the front axle can turn over by 90 degrees by matching with manpower; if the underframe 1 is inserted into the front axle fabrication hole, the hanger 2 is arranged below, the front axle can automatically turn over by 120-150 degrees under the action of gravity when lifted, and then the front axle can turn over by 180 degrees by matching with manual work when falling. The utility model discloses utilized the gravity of front axle self, made it overturn certain angle when lifting by crane, the manual work only need fall to the ground at the front axle and adjust its position of placing when placing, then continue the pine hoist, the front axle is from looking for the balance under the action of gravity to reach 90 or 180 effects of upset. And the hoisting ring 23 is rotatably connected with the pin shaft 22, so that the front shaft and the lifting appliance can be easily turned around the pin shaft 22 during hoisting.

In order to facilitate operation and prevent the locking plate 34 from freely rotating when the underframe 1 is inserted into the front axle fabrication hole, so that a worker cannot insert the underframe 1 by one hand, and the operation efficiency is affected, the round rod 31 is sleeved with a spring 35, and two ends of the spring 35 respectively abut against the lifting end of the underframe 1 and the locking plate 34; the spring 35 is a compression spring, under normal conditions, the locking plate 34 is pressed against the underframe 1 under the action of the spring 35 and cannot rotate, after the underframe 1 is inserted into the front axle process hole, a worker pulls the torsion plate 33 to separate the locking plate 34 from the underframe 1, rotates the torsion plate 33 to enable the locking plate 34 to rotate 90 degrees, releases the torsion plate 33, and presses the underframe 1 again after the locking plate 34 is erected, so that the locking plate 34 is controlled and cannot rotate under gravity or other external forces to cause the error unhooking during hoisting of the front axle.

In order to further increase the safety and prevent the locking plate 34 from being controlled and rotated manually, which causes difficulty in operation when the chassis 1 is inserted or unhooking when the chassis is lifted, two clamping plates 4 are arranged on the inner side of the insertion end of the chassis 1, the two clamping plates 4 are respectively arranged on the left side and the right side of the round rod 31, and the minimum distance between the two clamping plates 4 is greater than the thickness of the locking plate 34.

It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
