Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

Example 1

As shown in the combined drawing 1, the sublance lifting frame comprises a frame body 1 and lifting rings, wherein the lifting rings are respectively connected with two sides of the top surface of the frame body 1 through two lifting ropes 2, two lifting lugs can be arranged on the top surface of the frame body 1, two ends of the lifting ropes 2 are respectively connected with the lifting lugs and the lifting rings, the vertical line passing through the lifting rings passes through the gravity center of the frame body 1, one side of the bottom surface of the frame body 1 is provided with a plurality of binding ropes 6, each binding rope 6 comprises a hook 63, the hook 63 is respectively connected with one side of the bottom surface of the frame body 1 through a first lifting rope 61 and a second lifting rope 62, and the other side of the bottom surface of the frame body 1 is provided with a plurality of hanging holes 51 for hanging the hook 63. The first and second lifting ropes 61 and 62 are preferably soft ropes such as nylon ropes and belts, and have good binding property and certain friction force.

Further, in order to improve the strength of the frame body 1, a first rib plate 4 is arranged on one side of the bottom surface of the frame body 1, a second rib plate 5 is arranged on the other side of the bottom surface of the frame body 1, and the hanging hole 51 is arranged on the second rib plate 5.

When the sublance is dispatched and transported, the lifting ring is hooked by the lifting hook of the overhead traveling crane, the support body 1 is controlled to be located above the horizontally placed sublance, the center of gravity of the sublance may deviate from the center of the support body by a few degrees at the moment, the hook 63 penetrates through the lower part of the sublance, then the hook passes upwards through the upper part of the sublance, and then the hook passes through the lower part of the sublance, the hook 63 is upwards hung on the hanging hole 51, at the moment, the binding rope 6 is wound around the sublance for a circle, after the overhead traveling crane lifts the support body 1, under the action of the gravity of the sublance, the binding rope 6 can be tightly wound outside the sublance, and under the condition that the center of gravity of the sublance deviates from the center of the support body 1, the sublance causes the support body 1 to incline, the sublance is not easy to slide. Therefore, the sublance is not easy to fall off and be damaged in the process of distribution.

Example 2

When one of the two slings 2 is disconnected or falls off from the lifting lug for some reason, the end of the frame body 1 is caused to descend, even the end of the sublance collides with the ground, and in order to avoid the damage of the sublance caused by the collision with the ground as much as possible, the embodiment is improved on the basis of the embodiment 1 as shown in fig. 1-2 as follows: the utility model discloses a support body, including support body 1, both sides at both ends are provided with bedplate 3, one side that bedplate 3 upper portion is close to rings is provided with shaft hole 31, still includes buffer 7, buffer 7 is including rotating piece 71, the both sides that rotate piece 71 upper portion are provided with the pivot 711 of being connected with shaft hole 31 rotation, it has inserted bar 712 to rotate piece 71 at the position sliding connection of pivot 711 below, the below of shaft hole 31 and the one side of keeping away from rings are provided with the pinhole 32 that is used for inserting inserted bar 712, it has moving part 73 to rotate piece 71 lower part sliding connection, be provided with second spring 72 between moving part 73 and the rotation piece 71, the moving part 73 lower extreme rotates and is connected with gyro wheel 732. The length of the frame 1 should be close to the length of the sublance so that the sublance does not protrude or protrudes very little from the ends of the frame. Before hoisting, the buffer device 7 is in a horizontal state, when the sublance is bound by the binding rope 6 and is lifted for about 1 m, the inserted rod 712 is pulled out, the buffer device 7 is turned to a vertical state, and then the inserted rod 712 is inserted into the pin hole 32 below the shaft hole 31 to fix the buffer device. The lower end of the damping device 7 is lowered below the position of the sub lance. When one of two hoist cables 2 breaks off or drops with the lug because of some reason, will descend this end of support body back buffer 7 will contact with ground earlier, play the cushioning effect, reduce the dynamics of striking to the sublance is tied up and be difficult to the fly-out, ties up rope 6 and should be short a little as far as possible, can prevent to a certain extent that the sublance from colliding with ground and damaging.

Specifically, the rotating member 71 is provided with an accommodating cavity 713 at a position below the rotating shaft 711, a first spring 714 is arranged in the accommodating cavity 713, the insertion rod 712 penetrates through the first spring 714, a through hole capable of allowing the insertion rod 712 to penetrate out is arranged on the outer side of the accommodating cavity 713, the diameter of the through hole is smaller than the inner diameter of the first spring 714, a stop ring is arranged on the insertion rod 712, and the first spring 714 is located between the stop ring and the through hole. The plug 712 does not fall out of the pin hole 32 by itself.

Specifically, the lower end of the rotating member 71 is provided with a connecting plate 715, two sides of the connecting plate 715 are provided with guide holes, two sides of the upper end of the movable member 73 are provided with guide posts 731 slidably connected with the guide holes, the second spring 72 is sleeved outside the guide posts 731, one end of the guide posts 731, which is far away from the rotating member 71, is provided with an external threaded portion, and the nut is in threaded connection with the external threaded portion, so that the sliding connection between the rotating member 71 and the movable member 73 can be realized by the structure.
