Abstract
The utility model relates to a push rod for a crown block brake. The push rod for the crown block brake comprises connecting rods, a support, a cylinder piston rod, a brake and the like. One end of the first connecting rod is connected with the cylinder piston rod on the brake, the other end of the first connecting rod is connected with the second connecting rod through a cylindrical pin, the other end of the second connecting rod is connected with the support which is connected with one side of the first connecting rod, two ends of the third connecting rod are connected with the support, and roller bearings are mounted on two sides of the cylindrical pin. The push rod for the crown block brake has the advantages that the push rod is reasonable in structural design, production safety factor is increased, and especially, the problem of replacement of the brake due to abrasion of shaft pins and holes is solved, the service life of the brake is prolonged, and production cost is reduced.
Description
Technical field
The utility model belongs to a kind of day vehicle brake matching component, particularly relates to a kind of overhead traveling crane with electric power hydraulic block formula drg catch bar.
Background technology
At present, if the power hydraulic pressure block brake is a bad place in whole corollary equipment, the use, then need change equipment package.Moreover, be about 1 year the service life of catch bar point of connection, directly has influence on the brake safe of overhead traveling crane after catch bar pivot pin and the hole wearing and tearing.Above-mentioned situation causes that diversion fee is high, effort is time-consuming, and safety factor is low.
Summary of the invention
The utility model provides a kind of reasonable in design for solving the technical matters that exists in the known technology, can prolong the sky vehicle brake catch bar in drg life-span.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is:
A kind of day vehicle brake catch bar; Comprise connecting rod, support, oil cylinder piston bar, drg etc., it is characterized in that: an end of connecting rod links to each other with oil cylinder piston bar on the drg, and its other end links to each other with an end of connecting rod through straight pin; The other end of connecting rod is connected with support; Support is connected with a side of connecting rod, and the two ends of connecting rod are connected with support respectively, are fitted with antifriction-bearing box in the both sides of straight pin.
Advantage and the good effect that the utlity model has be: reasonable in design, improved the safety factor of producing, particularly solved the problem that need change drg because of the wearing and tearing in pivot pin and hole, prolonged drg life-span, reduced productive costs.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the birds-eye view of the described straight pin of the utility model.
Among the figure: 1, antifriction-bearing box; 2, connecting rod; 3, connecting rod; 4, connecting rod; 5, support; 5A, support; 6, oil cylinder piston bar; 7, straight pin; 8, drg.
The specific embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
As depicted in figs. 1 and 2, a kind of day vehicle brake catch bar comprises connecting rod, support, oil cylinder piston bar, drg etc.; One end of connecting rod 2 links to each other with oil cylinder piston bar 6 on the drg 8; Its other end links to each other with an end of connecting rod 3 through straight pin 7, and the other end of connecting rod 3 is connected with support 5, and support 5A is connected with a side of connecting rod 2; The two ends of connecting rod 4 are connected with 5A with support 5 respectively, are fitted with antifriction-bearing box 1 in the both sides of straight pin.
The principle of work of the utility model is: newspaper lock end straight pin 7 changes its antifriction-bearing box 1 into the cliding friction of support and cooperates, during drg 8 work, when the excitation coil of drg is connected rated voltage; The motor of hydraulic brake rotates, and drives the wheel rotation of hydraulic actuating cylinder, its with the effect of hydraulic oil under drive oil cylinder piston bar 6 upwards stretch out; 2 actions of piston rod drivening rod, pulling connecting rod 3,5 actions of connecting rod 3 pulling supports; Realize that connecting rod 4 rotates around bearing 1, accomplishes the action of braking with this.Moreover, also can guarantee under the situation long-time, that high-frequency uses, not go wrong.
