Abstract

The utility model discloses a non-joint conveyor, comprising a plurality of ring-shaped rubber layers and a plurality of successive enhanced layers arranged between the ring-shaped rubber layers. The utility model overcomes the trumpet-shaped conveyer caused by inaccurate cutting of straps or inaccurate alignment of straps in the jointing process when straps are adopted to joint the conveyor, thus, eliminates the problems like inconsistent stress and frequent deviation of the conveyor while in use; and the strength of the non-joint conveyor with the same material is greatly enforced because the enhanced layers are successive.

Description

Joint-free conveyer belt

Technical field

The utility model relates to a kind of load-transfer device.

Background technology

Existing load-transfer device all is that strip material passes through engaged at end and forms ring-type, and strip material is made up of rubber layer and steel wire enhancement Layer usually, junction joint method commonly used is to adhere to one deck rubber layer again by rivet connection or in the junction, the steel wire enhancement Layer of junction is not bonded with each other in the said method, thereby the intensity of load-transfer device is reduced greatly; In addition, in engaging process, the end part aligning that cuts strip material in inaccurate or the engaging process owing to strip material is inaccurate, load-transfer device after all causing easily engaging is horn-like, thereby make load-transfer device problems such as discontinuity, easy sideslip in use occur, and the problems referred to above appear in supper wide type load-transfer device especially easily.

The utility model content

At the problems referred to above, the purpose of this utility model be to provide a kind of intensity height, stressed evenly, be difficult for the joint-free conveyer belt of sideslip.

For achieving the above object, technical solution of the present utility model is:

A kind of joint-free conveyer belt is made up of ring-shaped rubber layer and the continuous enhancement Layer that is arranged at the ring-shaped rubber interlayer.

Further, the described continuous enhancement Layer method that adopted left-hand lay and right-laid by two steel ropes from the centre of described ring-shaped rubber layer respectively is entwined to both sides along the length direction of rubber layer.

Further, described continuous enhancement Layer is entwined from the beginning to the end continuously by the length direction of steel cable along the ring-shaped rubber layer.

Further, be parallel to each other in the described steel rope winding process braiding or interlacing or fried dough twist formula the braiding.

Further, described continuous enhancement Layer is made up of the several layers canvas, is separated with rubber layer between all between every two-layer canvas.

After adopting said structure, because the utility model load-transfer device is made up of ring-shaped rubber layer and continuous enhancement Layer, therefore avoided in engaging process, the end part aligning that cuts strip material in inaccurate or the engaging process owing to strip material is inaccurate, and the load-transfer device after causing engaging is trumpet-shaped situation generation, thereby avoid load-transfer device problems such as discontinuity, easy sideslip in use to occur, and, the belt intension of same material is strengthened greatly because enhancement Layer is continuous.

Fig. 3 is the another kind of winding method scheme drawing of the utility model steel rope;

Fig. 4 is the section drawing of another embodiment of the utility model.

The specific embodiment:

As shown in Figure 1, the utility model joint-free conveyer belt comprises ring-shaped rubber layer 1 and is arranged at the middle continuous enhancement Layer of this rubber layer, described continuous enhancement Layer can be selected the steel rope 2 of continuous winding as shown in Figure 1 for use, this steel rope 2 can adopt as shown in Figure 2, the method that is adopted left-hand lay and right-laid by two

steel ropes

21,22 from the centre of ring-shaped rubber layer respectively is entwined to both sides along the length direction of rubber layer, can adopt parallel as shown in the figure weave or interlacing method or fried dough twist formula weave etc. in the steel rope winding process; Described steel rope also can adopt as shown in Figure 3, be entwined continuously from the beginning to the end by the length direction of steel cable 23 along the ring-shaped rubber layer, can adopt parallel as shown in Figure 2 weave or interlacing method or fried dough twist formula weave etc. in the winding process, winding process can be finished or machinery is entwined by artificial winding;

Described continuous enhancement Layer also can be made up of several layers canvas 24 shown in Fig. 4 embodiment two, is separated with rubber layer between all between every two-layer canvas 24, and described each layer canvas all fits on the rubber layer, and the number of plies of canvas can be decided according to the actual strength needs of load-transfer device.

Claims
