Abstract
The utility model relates to a polyurethane repair strip for repairing damages of a conveyor belt, which belongs to the technical field of repair materials of conveyor belts. The technical problem to be solved is to provide the repair strip for the conveyor belt, which can well solve the problem of repairing the damages of the conveyor belt. The adopted technical scheme is as follows: the repair strip is in the shape of a long strip, one edge or two edges of the cross section is/are straight line edges, and other edges are combined by straight lines and circular arcs. According to different shapes of the cross sections, the repair strips can be divided into three types of flat repair strips, square repair strips and L-shaped repair strips. The square repair strips and the L-shaped repair strips are specially used for repairing damages on the edges of the conveyor belts, thereby filling in the blank of repairing the damages on the edges in the prior art. Thermoplastic polyurethane material is adopted in the polyurethane repair strip, thereby not only improving the mechanical properties of the repair strip, but also being more environment-friendly.

The utility model content
The utility model overcomes the deficiencies in the prior art, and technical matters to be solved provides a kind of polyurethane repairing bar that is used to repair the load-transfer device breakage, can be good at solving the damaged problem of repairing of load-transfer device.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is:
Be used to repair the polyurethane repairing bar of load-transfer device breakage, it is shaped as strip, and its cross-sectional plane has on one side or both sides are straight line, and all the other limits are the combination of straight line and circular arc.
A limit of repairing sliver transvers section is a straight line, and other limit is the combination on straight line and circular arc limit, and straight line constitutes trapezoidal with the circular arc limit.
Two limits of repairing sliver transvers section are straight line, and vertical mutually, and other limit is the circular arc limit, and straight line constitutes fan-shaped with the circular arc limit.
Two limits of repairing sliver transvers section are straight line, and vertical mutually, and the two other limit also is orthogonal straight line, is connected by circular arc between the straight line, and straight line constitutes " L " shape with the circular arc limit.
Repairing bar is made by the thermoplastic polyurethane material.
The beneficial effect that the utility model is compared with prior art had is:
1, repairing bar of the square in the utility model and L type are repaired the edge breakage that bar is used to repair load-transfer device, have filled up the blank of edge breakage reparation in the past.
2, because material of the present utility model has adopted thermoplastic polyurethane, thus wear-resisting, tension, obdurability and ageing-resistant characteristic had, and environmental protection.

Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of embodiment two;
Fig. 3 is the structural representation of embodiment three;
Fig. 4 is the running condition reference diagram of embodiment two;
Fig. 5 is the running condition reference diagram of embodiment three.
Among the figure 1 be flat repairing bar, 2 for square repair bar, 3 for the L type repair bar, 4 for load-transfer device, 5 for cambic horizon, 6 be weighting material.
The specific embodiment
As shown in Figure 1, the utility model is used to repair the polyurethane repairing bar of load-transfer device breakage, and it is shaped as strip, and its cross-sectional plane has on one side or both sides are straight line, and all the other limits are the combination of straight line and circular arc.
The polyurethane that the utility model is used to repair the load-transfer device breakage is repaired bar and is made by the thermoplastic polyurethane material.
Embodiment one
A limit of repairing sliver transvers section is a straight line, and other limit is the combination on straight line and circular arc limit, and straight line constitutes trapezoidal with the circular arc limit, and this repairs bar is flat repairing bar 1.
Embodiment two
As shown in Figure 2, two limits of repairing sliver transvers section are straight line, and vertical mutually, and other limit is the circular arc limit, and straight line constitutes fan-shaped with the circular arc limit, and this repairs bar is that square is repaired bar 2.
Square is repaired the breakage that bar 2 is bonded in belt edges, recovers the size of belt edges, prevents that material from falling, and prevents that steel wire from rubbing, preventing damaged expansion.
As shown in Figure 4, the using method of square repairing bar 2 is:
The first step, polishing: with side, upper surface, the lower surface of load-transfer device 4 the broken edges clean and roughening of angle grinding machine polishing, again the bonding plane of cambic horizon 5, flat repairing bar 1 and square repairing bar 2 is polished clean and roughening.
Second step, load-transfer device 4 chemical conversion treatment: at the side and the lower surface brushing rubberized liquid of load-transfer device 4.
The 3rd step, adhesive transition layer 5: brush coating stick twice on the side of load-transfer device 4 and cambic horizon 5, and drying in the air a moment, the bonding position to 50 of patterned heat is ℃-120 ℃ then, and cambic horizon 5 is pasted load-transfer device 4 sides, and grinding compacting.
The 5th step, bonding square are repaired bar 2: repair bar 1 on the plane and square is repaired brush coating stick twice on the bar 2, and dry in the air a moment, the bonding position to 50 of patterned heat is ℃-120 ℃ then, and square is repaired bar 2 stick on the edge that bar 1 is repaired on the plane, and grinding compacting.
The 6th step, blind:, be filled in square and repair in the slit at bar 2 and load-transfer device 4 edges, and solidify with the liquid polymers material of appointment.
Embodiment three
As shown in Figure 3, two limits of repairing sliver transvers section are straight line, and vertical mutually, and the two other limit also is orthogonal straight line, is connected by circular arc between the straight line, and straight line constitutes " L " shape with the circular arc limit, and this repairs bar and repairs bar 3 for the L type.
It is that flat repairing bar 1 is repaired 2 integration product with square that the L type is repaired bar 3, is bonded in less edge breakage place, prevents damaged expansion.
As shown in Figure 5, the using method of L type repairing bar 3 is:
