Abstract
The utility model relates to the field of engineering equipment, in particular to a safety suspension clamp for an impact grab bucket. The safety suspension clamp comprises an oil cylinder. The safety suspension clamp is characterized by comprising a support, clamp heads, connecting rods, clamp arms and springs; the support comprises two side plates and positioning plates symmetrically arranged at the side faces of the side plates, and sliding chutes are symmetrically arranged on the positioning plates; one ends of the two connecting rods are connected with a telescopic-end pin shaft of the oil cylinder, the other ends of the two connecting rods are respectively connected with top-end pin shafts of the two clamp arms, and the two clamp arms are connected with each other by the pin shafts; two ends of the springs are respectively and fixedly connected with the two clamp arms, and the springs are arranged above the a pin shaft connecting point between the two clamp arms; and the bottom ends of the two clamp arms are overhead hook-shaped, the tops of the clamp heads are overhead hook-shaped as well, and the clamp arms are in plugging connection with the clamp heads by the mutual meshing of overhead hooks of the clamp arms and the clamp heads. The design is adopted by the safety suspension clamp, so that the clamp heads and the impact grab bucket are fixedly connected with one another when the safety suspension clamp is used; and according to the action of the springs and the oil cylinder, the clamp heads are clamped by the clamp arms to be fixed to play a part in double insurance, so that the use safety of the impact grab bucket can be improved.
Description
Technical field
The utility model relates to the civil engineering plant field, is specially a kind of safety hanging clamp for Impact Bucket Grab.
Background technology
The multiplex steel rope of traditional Impact Bucket Grab cooperates winch to realize that suspention is fixing, and so, in case wire cable rupture or winch break down, Impact Bucket Grab just can be fallen, and causes the loss of ground construction personnel, preparation of construction, thereby has serious potential safety hazard.
Summary of the invention
The purpose of this utility model is to overcome existing steel rope, the existing defective of winch lifting Impact Bucket Grab, and a kind of multiple fixing safety hanging clamp that is used for Impact Bucket Grab is provided.
In order to achieve the above object, the utility model is achieved in that
A kind of safety hanging clamp for Impact Bucket Grab, it comprises oil cylinder, it comprises support, chuck, two connecting rods, two jig arm and spring; Support comprises two blocks of side plates and the locating plate that is symmetricly set in two side plate sides, and symmetry offers chute on the described locating plate; Two connecting rods all have an end to be connected with the telescopic end bearing pin of oil cylinder, and the telescopic end of oil cylinder is positioned at the chute of support, and the other end of two connecting rods is connected with the top bearing pin of two jig arm respectively, and bearing pin connects between two jig arm; Both ends of the spring is captiveed joint with two jig arm respectively, and spring is positioned at the top of the bearing pin point of connection of two jig arm; The bottom of two jig arm is barb-like, and it is barb-like that the chuck top also is, and jig arm and chuck are by the engaged realization socket connection of both barbs.
The utility model adopts above-mentioned design, during use chuck is captiveed joint with Impact Bucket Grab; Because the effect of spring and oil cylinder, chuck is gripped by jig arm, plays the effect of double insurance, thereby has improved the safety in utilization of Impact Bucket Grab.

Fig. 2 is the utility model status architecture schematic diagram that gets loose.
The specific embodiment
Below further specify the utility model by specific embodiment.
As shown in Figure 1 and Figure 2, a kind of safety hanging clamp for Impact Bucket Grab, it comprises oil cylinder 2, support 1, chuck 5, two connecting rods 4, two jig arm 3 and spring 6; Support 1 comprises two blocks of side plates and the locating plate that is symmetricly set in two side plate sides, and symmetry offers chute on the described locating plate; Two connecting rods 4 all have an end to be connected with the telescopic end bearing pin of oil cylinder 2, and the telescopic end of oil cylinder 2 is positioned at the chute of support 1, and the other end of two connecting rods 4 is connected with the top bearing pin of two jig arm 3 respectively, and 3 bearing pins of two jig arm connect; Captive joint with two jig arm 3 respectively in spring 6 two ends, spring 6 is positioned at the top of the bearing pin point of connection of two jig arm 3; The bottom of jig arm 3 is barb-like, and chuck 5 tops also are barb-like, jig arm 3 and the engaged realization socket connection of chuck 5 by both barbs.
The utility model adopts above-mentioned design, during use chuck is captiveed joint with Impact Bucket Grab; Because the effect of spring and oil cylinder; Chuck is gripped by jig arm when static, so, plays the effect of double insurance, thereby has improved the safety in utilization of Impact Bucket Grab; During action, oil cylinder receives action command and shrinks, and in the effect lower spring compression of connecting rod, jig arm is opened, and chuck breaks away from, and Impact Bucket Grab falls.
