Problems solved by technology

[0004] The purpose of the present invention is to actively push the guide slider to slide down to the right position when necessary through the sliding compensation mechanism installed in the pliers arm assembly, so as to solve the problem that the guide slider in the inclined slideway does not slide down in place and the clamping force is insufficient, resulting in the jaw teeth facing each other. The slab slips and even falls off

Embodiment Construction

[0014] like Figure 1~Figure 4 The shown electric translational slab tongs with a sliding compensation mechanism include an opening and closing mechanism 3, a clamp arm assembly 5, an upper beam 1, a lower beam 4, and a hanging beam frame 2. The opening and closing mechanism 3 includes a three-in-one driving motor , sprockets, chains, nuts and screw rods; the clamp arm assembly 5 includes inclined slideways, clamp frames, guide sliders 9, clamp teeth 10, sliding support hinges 11, and sliding compensation mechanisms 7.

[0015] The sliding compensation mechanism 7 is composed of a hydraulic combination oil cylinder integrating a return spring, especially a disc spring, which includes a coupling device 12, a gland 13, a piston rod 14, a small sleeve 15, a cylinder body 16, a spring 17, a spacer 18, and a piston 19 , Cylinder bottom 20; Among them, 12 is a connecting device, which connects the hydraulic combination oil cylinder and the guide slider 9 through a hinge; 13 is a gla...

Abstract

The invention discloses an electric translation slab clamp provided with a sliding compensation mechanism, wherein, the sliding compensation mechanism consists of an integrated return spring inside a hydrocylinder, which not only retains the original reset function, but also has the function of actively pushing a guide sliding block to slide backward in place. The invention changes the situations that set teeth skid relative to the slab and slab dropping happen, which are caused by that the guide sliding block does not slide backward in place in an inclined slideway and the clamping force is not enough due to the influence of temperature, lubrication ad the like on the electric translation slab clamp, and solves the slab dropping problem of the clamp.

Description

technical field [0001] The invention relates to a crane spreader, in particular to an electric translational slab clamp. Background technique [0002] The current electric translational slab tongs include an opening and closing mechanism, a clamp arm assembly, an upper beam, a lower beam, and a hanging beam frame. The upper and lower beams are connected by hanging beams and arranged vertically; the opening and closing mechanism is placed on the upper part and inside of the lower beam; the sliding guide structure assembled by the clamp arm is placed inside the lower beam. The working process of the tongs includes four stages: 1. Clamp closing stage: the opening and closing mechanism drives the assembly of the tong arms to run inward and opposite to each other until the teeth of the tongs press the two sides of the slab and generate a certain initial clamping force. The tightening force produces the initial friction force, and the resultant force of the friction force on the ...
