Detailed Description
The present invention will be further illustrated with reference to the accompanying drawings and specific embodiments, which are to be understood as merely illustrative of the invention and not as limiting the scope of the invention. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.
As shown in fig. 1, fig. 2 and fig. 3, the self-locking hoisting pin for holes of the present invention comprises a lifting platform and a guide chain; the butt joint end of the root of the guide chain 1 is in transmission connection with the hanging plate 2 through a fixing piece, an auxiliary mechanism is installed at the root of the hanging plate 2, the middle section of the hanging plate 2 is movably connected with the hanging rod 3 through a movable bolt, the hanging rod 3 is inserted into the guide sleeve 6 in the vertical direction, and the guide sleeve 6 is fixedly installed on the side wall of the lifting platform 8. Wherein, the utility model discloses to lift by crane chain 1 that leads of driving bottom and self-adaptation gravity lift by crane the self-lock device and be connected. Before that, an operator manually shifts the transverse hanging plate 2 back to a vertical state, and the hoisting self-locking equipment is fixedly butted with the butt joint end of the root part of the guide chain 1 on the hanging plate 2 to complete the initial hoisting connection process. And in the process that the hanging plate 2 is pulled back to the vertical state, the hanging rod 3 at the tail part of the hanging plate 2 moves downwards along the vertical direction until being inserted into the guide sleeve 6, and the head part positioning procedure is completed. Because the caliber of the guide sleeve 6 is larger than the width of the suspender 3, the root of the suspender 2 is provided with an auxiliary mechanism which can subsequently assist the suspender 3 to complete the locking process. The guide sleeve 6 is fixedly arranged on the side wall of the lifting platform 8, so that the guide sleeve 6 and the lifting platform 8 form an integrated structure.
As shown in fig. 1, 2 and 3, the auxiliary mechanism includes a connecting rod 4 and a positioning block 5, the top of the connecting rod 4 is in transmission connection with the folded edge at the root of the hanging plate 2 through a movable bolt, the root of the connecting rod 4 is fixedly connected with the bent arm of the positioning block 5 through a positioning bolt, and the positioning block 5 is selectively inserted into the guide sleeve 6 along the vertical direction. Wherein, the connecting rod 4 in the auxiliary mechanism is matched with the hanging plate 2 to vertically move in the process of vertical poking action, and the hem at the root of the connecting rod drives the connecting rod to vertically move downwards. In the movement process, the connecting rod 4 drives the positioning block 5 at the root of the connecting rod to be inserted into the guide sleeve 6, so that the positioning block 5 extrudes the suspender 3 to complete the self-locking process.
As shown in fig. 1, 2 and 3, the extending edge of the positioning block 5 is exposed along the left side edge of the suspension rod 3, the extending edge of the positioning block 5 is in pushing contact with the left side edge of the suspension rod 3, and the bottom end of the positioning block 5 is in an acute angle structure. The plane of the extending edge of the positioning block 5 is larger than the plane area of the side edge of the suspender 3, so that the situation that the suspender 3 and the positioning block 5 are laterally moved in the extrusion process can be avoided. The acute angle structure at the bottom end of the positioning block 5 is favorable for the positioning block 5 to be vertically inserted into the guide sleeve 6 filled with the suspender 3.
As shown in fig. 1, 2 and 3, the outer ring of the guide sleeve 6 is fixedly connected with a fixing frame through a reinforcing rib, the fixing frame is fixedly installed on the side wall of the lifting platform 8 through a fixing bolt, and a plurality of groups of fixing frames are uniformly distributed on the side wall of the lifting platform 8. Wherein, fixed intensity of guide pin bushing 6 is reinforceed to fixed frame accessible strengthening rib, has also disperseed the stress surface of guide pin bushing 6 simultaneously.
As shown in fig. 1, 2 and 3, a hanger bar boss 7 is installed at the bottom of the hanger bar 3, the horizontal size of the bottom of the hanger bar boss 7 is larger than that of the hanger bar 3, and the hanger bar boss 7 is in ejection contact with the bottom end of the guide sleeve 6. The suspender boss 7 can play a role in collision limitation and limit the upward movement of the guide sleeve 6 inserted in the guide sleeve 6.
The technical means disclosed in the invention scheme are not limited to the technical means disclosed in the above embodiments, but also include the technical scheme formed by any combination of the above technical features.
