Description
Technical field
The utility model relates to a kind of to pump truck end hose fixed mechanism, specifically, relates to a kind of pump truck end hose safety device.
Background technology
Development along with urban construction, urban construction is also more and more higher with dependence to the mechanization technical requirements, because concrete pump truck (abbreviation pump truck) is more flexible when fluid concrete, convenient, become one of leading equipment of fluid concrete in the building trade at present.Concrete mixer is the machinery that utilizes pressure that concrete is carried continuously along specific pipeline, and as shown in Figure 1, it mainly is made up of chassis 1, pumping mechanism 3, boom system 2 etc.Wherein boom system is part relatively more dangerous in the concrete mixer; Concrete conveying pipe 8 mainly by hinged forming such as more piece jib 4, connecting rod 5, oil cylinder 6 and connectors 7, is being fixed by system above the jib.As shown in Figure 2, cloth is provided with flexible pipe at the not end of pipeline, claims not hold flexible pipe 9.Do not hold the danger of flexible pipe 9 to be that swing, the factors such as pressure variation in the conveyance conduit 8 of jib 4 cause and do not hold flexible pipe 9 swings, and do not hold flexible pipe 9 to be and the scope of operation and the immediate position of operating personnel, generally not holding flexible pipe 9 to adopt length is 3 meters, so its deathtrap of having swung is the diameter range of hose length twice, namely 6 meters, so injure peripheral operating personnel easily.
At present, some concrete mixer manufacturers have have also researched and developed the swing that some devices reduce jib; But the pipeline inner concrete causes the moment swing of not holding flexible pipe still to exist with the variation of the frictional force of not holding flexible pipe and pipeline inner concrete pressure.
For example: Chinese patent, a kind of concrete mixer and terminal hose arrangement thereof, application number: CN201110025823.6, a kind of terminal hose arrangement of concrete mixer is disclosed, the traction element that comprises flexible pipe and the described hose movement direction of control, also comprise the outside that is arranged at described flexible pipe, and the flexible member along the axial stretching of described flexible pipe, both ends along the flexible direction of described flexible member are connected with the sidewall of described flexible pipe respectively, and an end of described traction element is connected with described flexible member; Operating personnel are when this hose arrangement of control, only need overcome flexible pipe along the active force of its axial float, and on guaranteeing that flexible pipe axially can movable basis along it, have the easier characteristics of control ratio, but this invention still can't solve the problem of end hose moment backswing, and the elasticity original paper damages to single easy appearance simultaneously.
Summary of the invention
The utility model is at the problem of the easy backswing that exists in the existing pump truck end hose, a kind of pump truck end hose safety device is provided, when not holding flexible pipe moment swing, limit its amplitude of oscillation, thereby reach the convenience that neither influences end hose, also improve the handling safety performance of not holding flexible pipe.
Scheme of the present utility model is by such realization: construct a kind of pump truck end hose safety device, be used for reducing the swing of end hose, comprise the retainer ring that is fixed on end hose top and the ring that resets that is fixed on the end hose middle part, the pulling force ring is movable up and down to be arranged in the end hose and at retainer ring with reset between the ring, it is connected with retainer ring by the pulling force safety rope that is arranged on the end hose limit, and described pulling force ring bottom is connected with the ring that resets by back-moving spring.
The know-why of the utility model scheme is: by the upper and lower of flexible pipe endways fixing two draw rings, and by pulling force safety rope and spring the pulling force ring of one activity slidably is arranged on the flexible pipe middle part.When end hose under normal mode of occupation, the amplitude of its swing is little, and because the safe nettle of pulling force is flexible, so do not influence the working region of end hose; When end hose is swung suddenly significantly, because the bending of end hose makes in the camber line and outer stressed the differing of the safe nettle of pulling force of camber line, the safe nettle pulling of the pulling force pulling force ring that camber line is outer, make pulling force ring and end hose form an angle and tightly block end hose, like this, the safe nettle of pulling force and pulling force ring have just tightly been held and have not been held flexible pipe, have limited and have not held soft amplitude of fluctuation; When not holding flexible pipe to turn back to the moment of upright position, the back-moving spring that is fixed on the ring that resets just is withdrawn into the pulling force ring on the home position automatically.Under action of inertia, do not hold flexible pipe still can swing to opposite direction, at this moment, the safe nettle of reciprocal pulling force and pulling force ring are tightly held in the other direction again and are not held flexible pipe; In addition, the ring that resets is fastened on and does not hold on the flexible pipe, holds the pulling force ring by the back-moving spring pretension, except allowing the pulling force ring resets, plays also fixedly that the pulling force ring can not rotate, and guarantees that the safe nettle of pulling force remains on the effect on the camber line.
In the utility model; as preferred version; described pulling force safety rope has 4; it is evenly distributed on the end hose limit; owing in 4 directions of not holding flexible pipe the safe nettle of pulling force is arranged; so no matter hold flexible pipe toward which direction swing all can not be restricted, thereby reach the effect of safeguard protection, and make the safe nettle of pulling force not influence the work of end hose.
In the utility model, as another kind of preferred version, described back-moving spring has the 8-10 bar, and it is evenly distributed on the end hose limit, and the back-moving spring of these quantity can make better that the pulling force ring resets rapidly.
In the utility model, as further restriction, the height size of described pulling force ring is 10-12cm, and described back-moving spring length is 1-3cm, the scope that existing 3 meters end hoses arrange that is based on more than is set, like this limit pendulum best results that is arranged so that end hose of position.
Substantive distinguishing features of the present utility model and progress are:
1. the utility model has the advantages that and limit can be to end hose moment swing the time, thereby improve the handling safety performance of end hose, the danger coefficient when reducing construction.
2. the utility model is simple in structure, and cost of manufacture is low, and the safe nettle of the pulling force of employing is arranged on the end hose periphery, and the soft material of matter is light, does not influence the use of end hose; The effect of back-moving spring simultaneously is, the pulling force ring can be withdrawn into the home position, also plays the effect that fixing pulling force ring can not rotate, and guarantees that the pulling force safety rope remains on the effect on the camber line.
3. the utility model is obvious to the restriction effect of end hose, can the swing of end hose all directions be limited.
4. the utility model is simple in structure, and cost of manufacture is low, is easy to be extended and applied.
