Embodiment Construction

[0011] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0012] Such as figure 1 As shown, an automatic hooking device for a gravity slab clamp includes two suspenders 11, 12, the suspenders 11, 12 are hingedly connected to the clamp body 100, and a multi-link is arranged between the two suspenders mechanism, including two first connecting rods 21, 22 and two second connecting rods 31, 32, one ends of the two first connecting rods 21, 22 are hinged to each other, and the other ends are respectively connected to the second connecting rods 31 One end of . The two second connecting rods 31, 32 are welded and fixed to the two suspension rods 11, 12 respectively. Two first links, two second links and two clamp booms form a five-bar linkage.

[0013] A limiting plate 40 is provided on the outside of each of the suspenders 11, 12 to limit the open...

Abstract

The present invention discloses an automatic coupling device for a gravity slab clamp, comprising two steeves. A multiple link lever mechanism is arranged between the two steeves. The multiple link lever mechanism comprises two first link levers and two second link levers. The two first link levers are hinged by one end, while the other ends are hinged to one end of each of the second link levers. The two second link levers are respectively connected with the two steeves. The device solves the difficulties that the length dimension of the lever member of the steeve device is excessive and the length of the hook neck of the correspondingly associated double hook is limited. Furthermore, the arranged hinge joint spoke avoids linear friction so that the device is practical and durable.

Description

technical field [0001] The invention relates to an automatic hooking device for gravity slab clamps. Background technique [0002] Usually, the vertical height of the lifting point of the suspension rod of the gravity slab clamp is relatively large, and the manual hook has potential safety hazards, and the labor intensity of the workers is very high. The automatic hook (double hook) device of the gravity slab tong is a mechanical device that uses the mechanical movement caused by the gravity of the hook to drive the suspension rod device of the gravity slab tong to close automatically, so as to achieve the purpose of automatic hooking. [0003] Some of the existing devices are only suitable for the gravity slab tongs under the condition that the rod length of the suspension rod device is not large and the length of the neck of the double hook is sufficient, or the device is fragile due to the friction force generated by linear motion. Contents of the invention [0004] Th...
