Woven strip of conveyor belt

 

(57) Abstract:

The invention relates to the field of the textile industry and relates to a woven strip of conveyor belt, made with synthetic weave of warp and weft threads. It is made of twisted yarns, plain weave with a relation of linear densities of the warp and weft of 0.95 to 1.00, with respect to technological density of 2.44-2,72, and its structure belongs 6,95-7,42 phase structure, while the woven strip has a filling on the basis of 74,75-78,35%, the padding duck 28,82-34-89%, arabuko warp 9,4-12,31%, arabuko weft threads of 5.3 to 7.1%, the coefficient of coupling is 6.19-6,44. This gasket has a minimal deformation elongation zone workloads. table 1.

The invention relates to the textile industry and can be used as a reinforcing traction strip one - and mnogoproletnyh conveyor belts, flat belts and other technical products with an elastomeric coating, mainly mnogoproletnyh conveyor belts designed for transportation of rock mass.

The basic technical requirements of a woven strip conveyor belts for transportation of mining mA is axenia to a minimum (no more than 3) number of inevitable processes fumbling conveyor belts in operation and the subsequent stretching and sufficient tensile load on a duck (not less than 25% of the breaking load of the warp), providing quality and reliable joining of the ends of the conveyor belt, precluding separation of the mechanical expansion joints. In addition, to avoid spreading of the warp and weft threads in the process are woven strip conveyor belts must have a high coefficient of coupling threads (not less than 5.0).

Known woven strip conveyor belt made polutorapolnymi weave formed by joining two chetyrehrjadnyh (front and back) satin weave by alternating front and back of the main beams, United by a common weft [Patent Germany 2436922, CL 29 D 29/00, D 03 D 1/00, 65 G 15/30].

This woven strip conveyor belt due to insufficient compaction of the warp and weft has a significant drawback - the distance between the threads in process, due to the low coupling coefficient, equal 1,01.

Also known woven strip conveyor belt containing interwoven longitudinal - basic and cross - weft yarn. The main threads are arabuko to 22.5%, and the weft yarn diameter in the range of 0.2-1.0 mm [Patent Germany 25194448, CL 65 G 15/34].

T workloads, due to the high orebody warp, and low strength on a duck. As a consequence, the woven strip can be used in conveyor belts of low load. In addition, this woven strip is the ratio of the breaking loads on the basis of duck and not exceeding 20%, which is insufficient to ensure the quality of the dock.

Closest to the technical essence and the achieved result is woven strip of conveyor belt fabric TC-200-2 having to 7.77-7.87 order phase structure formed by the interweaving of the two systems woven synthetic perpendicular yarns, the filling on the basis of equal 93,69-97,37%, the padding duck 34,91-38,59, the ratio of the linear density of warp and weft threads is 1.0, the ratio of technological densities in the warp and weft is 2,43-2,79, robotka warp 16.6-19,41%, the elongation of the fabric in a range of working loads (10% elongation) 6,01,0 and technological shrinkage on the basis of the hot air is 9,02,0% ["polyamide Fabric for conveyor belts and flat belts" GOST 18215-87].

The disadvantage of this woven strip conveyor belts are significant deformation extending to frequent perestykoval conveyor belt during operation (>4).

An object of the invention is the creation of a woven strip of conveyor belt for transportation of rock mass with minimal (not more than 4.5%) deformation movements in the area of workloads, providing reduced to a minimum (no more than 3) number of inevitable processes fumbling conveyor belts in operation and subsequent stretching.

This problem is solved by the fact that the structure of the woven strip conveyor belt belongs 6,95-7,42 phase structure made of plain weave woven synthetic yarns with respect to the linear densities of the warp and weft of 0.95 to 1.00, with respect to technological densities in the warp and weft of 2.44-2,72, filled on the basis of 74,75-78,35%, filling in duck 28,82-34-89%, urabotat warp 9,40-12,31%, urabotat threads duck and 5.30-7,10%, the coefficient of coupling is 6.19-6,44.

These distinctive features, each separately and all together are significant, aimed at solving the problem.

The inventive structure allows the fabric to obtain a woven strip of conveyor belt with elongation in the range of operating loads 2,5-4,5%, sufficient tenacity on a duck (not less 42,0% from bursting on khnichenkova of the invention were experimental samples of woven strips of conveyor belts of the proposed design.

Samples of woven strips of conveyor belts, corresponding to the formula of the invention, with a positive result tested at ZAO kurskrezinotehnika". Test results the woven frames recommended for industrial application in mnogoproletnyh conveyor belts and flat transmission belts, received trade mark TLA-200-3M, TLC-200-3M, t-200-3M, they are drawn up, agreed and approved by the technical conditions of JSC "NIIT" THE 8378-024-00302379-2000 (extract from the test report attached).

Main technical characteristics of the prototype and the proposed structures of woven strips are summarized in table. The table shows that the inventive woven strip surpass woven strip - prototype in terms of elongation in the range of workloads in 2.0-2.8 times, against breaking loads on the basis of duck and 16.7-30,5%, which ensures that during operation of conveyor belts based on the proposed woven strips minimum degree of vitiagivaet and reduce the number of inevitable Perestyuk conveyor belts.

Woven strip conveyor belts, made by synthetic weave of warp and weft threads, characterized in that it is made of twisted yarns of lunesta 2,44-2,72, and its structure belongs 6,95-7,42 phase structure, while the woven strip has a filling on the basis of 74,75-78,35%, the padding duck 28,82-34,89%, arabuko warp 9,4-12,31%, arabuko weft threads of 5.3 to 7.1%, the coefficient of coupling is 6.19-6,44.
