Description
Изобретение относитс к горной промышленности, а конкретнее к землеройным машинам.The invention relates to the mining industry, and more specifically to earth-moving machines.
Известно устройство дл разработки м гких пород способом обрушени ,, включающее самоходную тележку, платформу с дйухканатной подвеской, рабочим органом и стабилизирующими кронштейнами fl ..A device for developing soft rocks by the method of collapse is known, which includes a self-propelled trolley, a platform with a rope suspension, a working body and stabilizing brackets fl ..
Однако двухканатна подвеска и стабилизирующие кронштейны платформы не обеспечивают точности при удержании машины в заданном направлении из-за неровной навивки кана- ов на барабан. Последнее объ сн етс различными изменени ми длин канатов и диаметров навивки из-за их выт жки и загр знени .However, a two-gang suspension and stabilizing brackets of the platform do not provide accuracy when holding the machine in a given direction due to uneven winding of channels onto the drum. The latter is due to various changes in rope lengths and winding diameters due to their stretching and contamination.
Известна также машина дл разработки пород, включающа самоходную тележку, платформу с канатной подвеской/ рабочим органом и датчиком положени блока канатной подвески 2.A machine for developing rocks is also known, which includes a self-propelled trolley, a platform with a cable suspension / implement and a sensor for positioning the cable suspension block 2.
Недостатком машины вл етс низ-ка точность обеспечени направленного движени рабочего органа, особенно при значительных на него толчковых нагрузках в период входа рабочего органа в забой и при преодолении твердых включений. Это объ сн етс тем.The disadvantage of the machine is the low accuracy of providing directional movement of the working body, especially when there are significant jolts on it during the period when the working body enters the face and when overcoming solid inclusions. This is so.
что перемещение -блока канатной подвески платформы осуществл етс при раздвижке гидроцилиндра по дуге окружности с радиусом, равным длине корфмысла. Така траектори обуславливает выполнение работы гидроцилиндром по перемещению платформы относительно канатной подвески в продольном направлении. При малых приращени х that the movement of the α-block of the cable suspension of the platform is carried out when the hydraulic cylinder is moved apart along an arc of a circle with a radius equal to the length of the corm of the arm. Such a trajectory causes the work of the hydraulic cylinder to move the platform relative to the cable suspension in the longitudinal direction. At small increments
10 силы сопротивлени поступательному движению рабочего органа в процессе подрезани уступа эта работа незначительна и мало сказываетс на процессе стабилизации положени рабочего орга15 на в забое. При значитеиьных приращени х силы сопротивлени выполнение работы по дополнительному перемещению платформы из-за конечной мощности гидроцилйндра приводит к замедлению 10, the force of resistance to the translational movement of the working body in the process of cutting the ledge, this work is insignificant and has little effect on the process of stabilizing the position of the working body on the face. When significant increments of the resistance force, the performance of work on the additional movement of the platform due to the final power of the hydrocylinder leads to a slowdown
20 процесса восстановлени первоначального положени платформы, снижаетс КПД узла стабилизации. В итоге снижаетс производительность машины.20, the process of restoring the platform to its original position reduces the efficiency of the stabilization unit. As a result, the performance of the machine decreases.
Цель изобретени - повышение произ25 водительности путем улучшени стабилизации положени рабочего органа.The purpose of the invention is to increase the productivity by improving the stabilization of the position of the working member.
Цель достигаетс тем, что машина дл разработки пород способом обрушени , включающа самоходную тележку, The goal is achieved by the fact that the machine for the development of rocks by the method of breaking, including a self-propelled car
