Abstract

The utility model relates to a clamping device for a carbon brick. The clamping device for the carbon brick comprises a small hanging beam, pull arms, clamping arms, an upper pin shaft, a lower pin shaft and anti-skid clamping plates and is characterized in that shaft holes are formed at two ends of the pull arms; shaft holes are formed at the upper ends and in the middles of the clamping arms; upper shaft holes of the two pull arms are overlapped and hinged; lower shaft holes of the two pull arms are hinged with the upper shaft hole of one clamping arm respectively; and the shaft holes in the intersected middles of the two clamping arms are overlapped and hinged; the pull arms and the clamping arms for a four-linkage mechanism and form a clamping arm; two sets of clamping arms are arranged in parallel; two ends of the small hanging beam are connected with the upper shaft holes of the pull arms of the two sets of clamping arms; the upper pin shaft is connected with the pull arms of the two sets of clamping arms and the hinged shaft holes of the clamping arms; the lower pin shaft is connected with the middle shaft holes of the clamping arms of the two sets of clamping arms; and one anti-skid clamping plate is arranged at the lower end of each clamping arm. The clamping device for the carbon brick has the advantages that in the process of mounting and transporting the carbon bricks, the action such as clamping, lifting, operating, loosing and the like can be implemented quickly.

Description

The carbon brick gripping mechanism

Technical field:

The utility model relates to a kind of carbon brick gripping mechanism, belongs to the gripping mechanism field of building metallurgical construction.

Background technology:

In metallurgical construction, the furnace lining of some metallurgical industrial furnace etc. need to adopt carbon brick as refractory material.Build by laying bricks or stones such as adopting carbon brick at the bottom of the State of Blast Furnace of ironmaking usefulness; Also have the furnace bottom of the electrolytic bath of electrolgtic aluminium also to build by laying bricks or stones with carbon brick, this moment, carbon brick was both worked as refractory material, worked as the cathode block of conduction usefulness again.The monolithic weight of these carbon bricks is generally the hundreds of kilogram, therefore in transportation, needs lifting in the processes such as installation.General carbon brick is a strip, and cross sectional shape be near square, and needs used the clamp clamps carbon brick in hoisting process, operation such as sling again, fall.Thereby need a kind of high-efficiency reliable instrument to supply the workmen to use.

Summary of the invention:

The purpose of the utility model provides a kind of carbon brick that can failure-free clamps, and can enough hoist cables or the sling carbon brick gripping mechanism of carbon brick of suspension hook failure-free.

The purpose of the utility model realizes in the following manner:

The utility model comprises little hanging beam, torque arm, jig arm, upper pin, lower bearing pin, anti-skidding clamping plate; It is characterized in that: all there is axis hole at the two ends of torque arm; The upper end and the middle part of jig arm are provided with axis hole; With the overlapping hinge of the upper shaft hole of two torque arm connect, the lower shaft hole of two torque arm is connected with the upper shaft hole hinge of a jig arm respectively, two jig arm intersects in the middle part of the overlapping and hinge connection of axis hole; Torque arm and jig arm form four-bar linkage, constitute a cover holder arms of the utility model, and two cover holder arms are laterally arranged; The upper shaft hole that connects the torque arm of two cover holder arms therebetween with the two ends of little hanging beam as hinge axis respectively; Connect the torque arm and the hinged axis hole of jig arm of two cover holder arms with the two ends of upper pin respectively as hinge axis, connect two with the two ends of lower bearing pin respectively as hinge axis and overlap the middle part axis hole of the jig arm of holder arms, anti-skidding clamping plate are installed in the lower end of each jig arm.

The utility model has the advantages that: install at carbon brick, can fast speed in the transportation implement clamping, lifting, operation, action such as unclamp.

Description of drawings:

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the lateral plan of Fig. 1.

The specific embodiment:

With reference to accompanying drawing, the utility model comprises little hanging beam 1, torque arm 2, jig arm 7, upper pin 3, lower bearing pin 6, anti-skidding clamping plate 8, and torque arm 2 usefulness steel plates are processed, and two ends are porose, and little hanging beam 1 is inserted in the upper end, and bearing pin 3 is plugged in the lower end; Jig arm 7 is also processed by steel plate, and the upper end and the middle part of jig arm 7 are provided with axis hole.With the overlapping hinge of the upper shaft hole of two torque arm 2 connect, the lower shaft hole of two torque arm 2 is connected with the upper shaft hole hinge of a jig arm 7 respectively, two jig arm 7 intersects in the middle part of the overlapping and hinge connection of axis hole; Torque arm 7 forms four-bar linkage with jig arm 2; Constitute a cover holder arms of the utility model; Two cover holder arms are laterally arranged; Connect the upper shaft hole of the torque arm of two cover holder arms with the two ends of little hanging beam 1 respectively as hinge axis therebetween, the termination is fixing with zero diopter pad 4, nut 5, connects two with upper pin 3 respectively as hinge axis and overlaps the torque arm of holder arms and the hinged axis hole of jig arm; Connect two with lower bearing pin 6 respectively as hinge axis and overlap the middle part axis hole of the jig arm of holder arms, anti-skidding clamping plate 8 are installed in the lower end of each jig arm 7.

During use, hang little hanging beam 1, for ease lifting with suspension hook or hoist cable; Middle part at little hanging beam 1 is provided with lifting hole(eyelet), and this device is put in the centre on the carbon brick 9, and draws back jig arm 7; Make it be in the state of clamping carbon brick 9, when suspension hook lifted by crane, this clamp just can be clamped carbon brick and lift by crane simultaneously; When carbon brick fell within the desired location, clamp also unclamped automatically when suspension hook or hoist cable unclamped.
