Description
СЕКЦИЯ МЕХАНИЗИРОВАННОЙ КРЕПИ SECTION OF MECHANIZED FASTENERS
ОПИСАНИЕ DESCRIPTION
Область техники Technical field
Предлагаемое техническое решение относится к машиностроению, а именно, к механизации процесов крепления и управления кровлей при подземной добыче полезных ископаемых. The proposed technical solution relates to mechanical engineering, namely, to the mechanization of the processes of attaching and controlling the roof during underground mining.
Предшествующий уровень техники State of the art
Из уровня техники наиболее близкой по конструкции, взятой за прототип, является секция механизированной крепи, которая включает перекрытие, гидростойки, два основания, между которыми установлены шарнирные святи и расположен механизм перемещения, два рычага, закрепленных на каждом основании с возможностью ограничения поворота и взаимодействия с механизмом перемещения, и гидродомкрат подъема, шарнирно соединенный штоком с одним из рычагов, который отличается тем, что цилиндр гидродомкрата подъема шарнирно соединен со вторым рычагом и ось гидродомкрата подъема перпендикулярна направлению перемещения секции. [1] From the prior art, the closest in design taken as a prototype is a section of powered roof support, which includes a ceiling, water stands, two bases, between which hinged sockets are installed and a movement mechanism is located, two levers fixed on each base with the possibility of restricting rotation and interacting with a movement mechanism, and a lifting jack pivotally connected by a rod to one of the levers, which is characterized in that the cylinder of the lifting jack is pivotally connected to the second lever and s hydraulic jack lifting section perpendicular to the direction of movement. [one]
Недостатком конструкции по прототипу является то, что она не обеспечивает достаточную высоту подъема оснований секции во время перемещения самой секции, поэтому возникает необходимость дополнительно вручну расчищать путь перемещения. Особенно эта проблема актуальна в условиях слабых и разрушенных почв, корда основания секции под действием горного давления заглубляются в почву, что значительно усложняет и замедляет процесс перемещения секции. Также передняя часть оснований секции уже во время перемещения может
«срезать» верхний слой почвы, что приводит к дальнейшему заглублению в почву и загромождению рабочего пространства. Конструкция секции по прототипу не позволяет увеличивать высоту подъема основания без увеличения габаритов секции в ширину, потому что линия контакта носка рычага с толкателем механизма перемещения секции одного из рычагов и линия контакта носка рычага с толкателем механизма перемещения секции противоположно установленного рычага находяться на одной прямой. Таким образом, увеличивать длину носка рычага возможно только в пределах от точки шарнирного крепления каждого из рычагов с соответствующим основанием до оси секции, что не достаточно для решения проблемы. The disadvantage of the design of the prototype is that it does not provide a sufficient height of the base of the section during the movement of the section itself, so there is a need to additionally manually clear the travel path. This problem is especially relevant in conditions of weak and destroyed soils, the cord of the base of the section under the influence of rock pressure is buried in the soil, which greatly complicates and slows down the process of moving the section. Also, the front of the base of the section already during movement can “Cut off” the topsoil, which leads to further deepening into the soil and clutter of the working space. The design of the section according to the prototype does not allow increasing the height of the base without increasing the width of the section, because the contact line of the toe of the lever with the pusher of the mechanism for moving the section of one of the levers and the line of contact of the toe of the lever with the pusher of the mechanism for moving the section of the opposite lever is located on one straight line. Thus, it is possible to increase the length of the toe of the lever only within the range from the pivot point of each of the levers with the appropriate base to the axis of the section, which is not enough to solve the problem.
Раскрытие изобретения Disclosure of invention
В основу предлагаемого технического решения поставлена задача усовершенствования конструкции секции, взятой за прототип, которая обеспечит увеличение высоты подъема оснований секции. Эта задача решается путем расположения носков рычагов таким образом, что линия взаимодействия с толкателем носка одного рычага смещена вдоль продольной оси секции относительно линии взаимодействия с толкателем носка противоположно установленного рычага с возможностью захода носков рычагов на половину секции, противоположную от шарнира крепления соответствующего рычага к основанию, при чем величина захода каждого носка определяется зависимостью 0 < а < А/2, где а - величина захода носка; А - ширина толкателя механизма передвижения. The basis of the proposed technical solution is the task of improving the design of the section, taken as a prototype, which will increase the height of the lifting base of the section. This problem is solved by arranging the socks of the levers in such a way that the line of interaction with the pusher of the sock of one lever is offset along the longitudinal axis of the section relative to the line of interaction with the pusher of the sock of the oppositely mounted lever with the possibility of the socks of the levers entering half the section opposite from the hinge of the corresponding lever to the base, moreover, the magnitude of the approach of each sock is determined by the dependence 0 <a <A / 2, where a is the magnitude of the approach of the sock; A is the width of the pusher of the movement mechanism.
При таком решении достигается технический результат, который заключается в обеспечении увеличения высоты подъема секции без изменения ее габаритов. Это достигается за счет смещения вдоль продольной оси секции линии контакта носка рычага с толкателем
механизма перемещения секции одного из рычагов относительно линии контакта носка рычага с толкателем механизма перемещения секции противоположно установленного рычага таким образом, чтобы эти линии не находились на одной прямой. Это в свою очередь позволит носкам рычагов заходить на половину секции, противоположную от шарнира крепления соответствующего рычага к основанию. Кроме того, заявляемая конструкция позволяет выбирать необходимую высоту подъема оснований секции от минимальной до максимальной за счет выбора величины захода носка за продольную ось секции в пределах от расположения линии контакта носка рычага с толкателем на самой продольной оси до захода на величину, равную половине ширины толкателя. With this solution, a technical result is achieved, which consists in providing an increase in the lifting height of the section without changing its dimensions. This is achieved by shifting along the longitudinal axis of the section of the contact line of the toe of the lever with the pusher the mechanism for moving the section of one of the levers relative to the contact line of the toe of the lever with the pusher of the mechanism for moving the section of the opposite mounted lever so that these lines are not on one straight line. This, in turn, will allow the socks of the levers to go into the half section, opposite from the hinge of the corresponding lever to the base. In addition, the claimed design allows you to select the required height of the base of the section from minimum to maximum due to the choice of the approach of the sock for the longitudinal axis of the section, ranging from the location of the contact line of the toe of the lever with the pusher on the longitudinal axis to the approach by an amount equal to half the width of the pusher.
Поставленная задача решается тем, что к известным признакам секции механизированной крепи, включающей перекрытие (1), гидростойки (2), гидродомкрат подъема (4) оснований, два шарнирно связанных между собой основания (3) с возможностью размещения между ними механизма перемещения секции (5), на которых симметрично относительно продольной оси секции (6) шарнирно закреплены два рычага (7),(8), связанные между собой гидродомкратом подъема (4) посредством шарнирных соединений плеча одного рычага со штоком (9) гидродомкрата подъема (4), а плеча противоположного рычага с гидроцилиндром (10), при этом рычаги установлены носками (1 1 , 12) навстречу друг другу с возможностью взаимодействия последних с толкателем (13) механизма перемещения секции (5), в соответствии с предлагаемым техническим решением носки ( 1 1 ),( 12) рычагов располагают таким образом, что линия (14) взаимодействия с толкателем (13) носка (1 1) одного рычага (7) смещена вдоль продольной оси (6) секции относительно линии (15) взаимодействия с толкателем (13) носка (12) противоположно установленного рычага (8) с возможностью захода
носков рычагов на половину секции, противоположную от шарнира крепления соответствующего рычага к основанию, при чем величина захода каждого носка определяется зависимостью 0 < а < А/2, где а - величина захода носка; А - ширина толкателя (13) механизма перемещения (5). The problem is solved in that to the well-known features of the mechanized roof support section, which includes the overlap (1), the hydraulic stand (2), the lifting jack (4) of the bases, two bases (3) articulated to each other with the possibility of placing a section moving mechanism between them (5 ) on which two levers (7), (8) are connected pivotally symmetrically with respect to the longitudinal axis of the section (6), interconnected by a lifting jack (4) by means of hinged joints of the arm of one arm with the rod (9) of the lifting jack (4), and shoulder opposite lever with a hydraulic cylinder (10), while the levers are installed with socks (1 1, 12) to meet each other with the possibility of interaction of the latter with the pusher (13) of the movement mechanism of the section (5), in accordance with the proposed technical solution of the socks (1 1), (12) the levers are positioned so that the line (14) of interaction with the pusher (13) of the sock (1 1) of one lever (7) is offset along the longitudinal axis (6) of the section relative to the line (15) of interaction with the pusher (13) of the sock ( 12) the opposite mounted lever (8) with the possibility of entry the socks of the levers to half the section, opposite from the hinge of fastening the corresponding lever to the base, and the approach value of each sock is determined by the dependence 0 <a <A / 2, where a is the approach value of the sock; And - the width of the pusher (13) of the movement mechanism (5).
Причинно-следственная связь между существенными признаками предлагаемого технического решения и достигаемым техническим результатом, поясняется следующим. Высота подъема секции зависит от длины плеча рычага с носком. Если просто увеличивать длину этого плеча рычага конструкции по прототипу, то это приведет к увеличению габаритов секции по ширине, т.к. линии контактов носков обоих рычагов с толкателем механизма перемещения расположены на одной прямой и продолжить носки рычагов без увеличения габаритов секции возможно только в пределах своей для каждого соответствующего рычага половины секции (до продольной оси секции). Введение в формулу предлагаемого технического решения нового признака - носки (1 1), (12) рычагов (7), (8) расположены таким образом, что линия (14) взаимодействия с толкателем носка (1 1) одного рычага (7) смещена вдоль продольной оси (6) секции относительно линии (15) взаимодействия с толкателем носка ( 12) противоположно установленного рычага (8) с возможностью захода носков (1 1),(12) рычагов (7), (8) на половину секции, противоположную от шарнира крепления соответствующего рычага к основанию, при чем, величина захода каждого носка определяется зависимостью 0 < а < А/2, где а - величина захода носка; А - ширина толкателя (13) механизма перемещения (5), позволяет выбирать необходимую высоту подъема оснований в зависимости от состояния почвы, исходя из того, что она пропорционально зависит от длины плеча рычага с носком, и может бать в пределах от минимальной до максимальной. Именно эти существенные
признаки обеспечивают технический результат - увеличение высоты подъема секции без изменения ее габаритов. A causal relationship between the essential features of the proposed technical solution and the achieved technical result is explained as follows. The lifting height of the section depends on the length of the shoulder of the lever with the toe. If you simply increase the length of this shoulder of the lever of the design according to the prototype, this will lead to an increase in the dimensions of the section in width, because the contact lines of the socks of both levers with the pusher of the displacement mechanism are located on one straight line and it is possible to continue the socks of the levers without increasing the dimensions of the section only within their own limits for each corresponding lever of the half section (to the longitudinal axis of the section). Introduction to the formula of the proposed technical solution of a new feature - socks (1 1), (12) of the levers (7), (8) are located in such a way that the line (14) of interaction with the pusher of the sock (1 1) of one lever (7) is shifted along the longitudinal axis (6) of the section relative to the line (15) of interaction with the toe pusher (12) of the opposite mounted lever (8) with the possibility of the socks (1 1), (12) of the levers (7), (8) entering the half of the section opposite from the hinge of fastening the corresponding lever to the base, and the approach value of each sock is determined by the dependence 0 < a <A / 2, where a is the value of the toe entry; A - the width of the pusher (13) of the movement mechanism (5), allows you to choose the required height of the base, depending on the condition of the soil, based on the fact that it proportionally depends on the length of the shoulder of the lever with the toe, and can be in the range from minimum to maximum. It is these essential the signs provide a technical result - an increase in the lifting height of the section without changing its dimensions.
Достижение заявляемого технического результата обеспечивает потребительские свойства предлагаемого технического решения, а именно, повышает производительность труда, так как уменьшает долю ручного труда по зачистке пути перемещения секции, улучшает состояние техники безопасности. Achievement of the claimed technical result provides consumer properties of the proposed technical solution, namely, it increases labor productivity, as it reduces the proportion of manual labor for cleaning the section moving path, improves the state of safety.

Секция механизированной крепи состоит из перекрытия ( 1), гидростоек (2), которые в верхней части связаны с перекрытием ( 1), а в нижней - с двумя связанными между собой основаниями (3), между которыми размещен механизм перемещения (5) секции, в состав которого входит толкатель (13) и гидродомкрат (16). На каждом основании (3) симметрично относительно продольной оси (6) шарнирно закреплены рычаги (7) и (8). Рычаги (7) и (8) связаны между собой гидродомкратом подъема (4) оснований (3). Один из рычагов (7) шарнирно соединен со штоком (9) гидродомкрата подъема (4), а противоположный рычаг (8) шарнирно связан с гидроцилиндром (10) гидродомкрата подъема. Рычаги (7) и (8) имеют носки (11) и (12), которые непосредственно контактируют с толкателем ( 13) во время перемещения секции. Рычаги (7) и (8) прикреплены к основаниям (3) таким образом, что их носки (1 1) и ( 12) направлены навстречу друг другу, но линии контакта носков (1 1) и (12) с толкателем ( 13) не образуют единую прямую, а смещены одна относительно другой вдоль продольной оси (6) секции таким образом, что носки (И) и (12) имеют возможность пересекать ось (6) и заходить на половину секции, противоположную от шарнирного крепления соответствующего рычага к основанию. The mechanized roof support section consists of a ceiling (1), hydraulic stands (2), which in the upper part are connected with the ceiling (1), and in the bottom - with two interconnected bases (3), between which the movement mechanism (5) of the section is located, which includes a pusher (13) and a hydraulic jack (16). On each base (3), levers (7) and (8) are symmetrically relative to the longitudinal axis (6). The levers (7) and (8) are interconnected by a lifting jack (4) of the bases (3). One of the levers (7) is pivotally connected to the rod (9) of the lifting jack (4), and the opposite lever (8) is pivotally connected to the hydraulic cylinder (10) of the lifting jack. The levers (7) and (8) have socks (11) and (12), which are in direct contact with the pusher (13) during the movement of the section. The levers (7) and (8) are attached to the bases (3) so that their socks (1 1) and (12) are directed towards each other, but the contact lines of the socks (1 1) and (12) with the pusher (13) they do not form a single straight line, but are displaced one relative to the other along the longitudinal axis (6) of the section so that the socks (I) and (12) are able to cross the axis (6) and go halfway into the section opposite from the hinged mounting of the corresponding lever to the base .
Промышленная применимость Секция механизированной крепи работает следующим образом. В рабочем состоянии перекрытие ( 1) и основания (3) прижаты гидростойками (2) к кровле и почве. Для перемещения секции гидростойки (2) складывают. Одновременно складывают гидродомкрат подъема (4), что сопровождается сближением шарнирных узлов, которые расположены на
штоке (9) и гидроцилиндре (10) и поворотом рычагов (7) и (8) до упора их носков ( 1 1) и (12) в толкатель (13). При этом передние части оснований (3) секции поднимаются относительно толкателя (13), прижимая его к почве. Перемещения секции осуществляют путем раздвижки гидродомкрата перемещения (16). В это время положение гидродомкрата подъема (4) остается неизменным за счет поддержания постоянного давления жидкости в гидросистеме, что обеспечивает поднятыми над почвой передние части оснований (3) до завершения процесса перемещения. Носки (1 1) и ( 12) рычагов (7) и (8) скользят по поверхности толкателя ( 13). После окончания процесса перемещения секции производят ее распор и одновременно раздвижку гидродомкрата подъема (4), что сопровождается отдалением шарнирных узлов, которые размещены на штоке (9) и гидроцилиндре (10), и поворотом рычагов (7) и (8) в обратном от толкателя ( 13) направлении, что поднимает носки (1 1), (12), и основания (3) опускаются на почву. Industrial applicability Section powered roof supports as follows. In working condition, the ceiling (1) and the base (3) are pressed against the roof and soil by hydrostations (2). To move the section of the hydraulic stand (2) is folded. At the same time, the lifting jack (4) is folded, which is accompanied by the approximation of the hinge nodes, which are located on the rod (9) and the hydraulic cylinder (10) and turning the levers (7) and (8) until their socks (1 1) and (12) abut against the pusher (13). In this case, the front parts of the bases (3) of the section rise relative to the pusher (13), pressing it to the soil. The movement of the section is carried out by sliding the hydraulic jack of movement (16). At this time, the position of the lifting jack (4) remains unchanged by maintaining a constant fluid pressure in the hydraulic system, which ensures that the front parts of the bases (3) are raised above the soil until the completion of the displacement process. Socks (1 1) and (12) of levers (7) and (8) slide along the surface of the pusher (13). After the end of the process of moving the section, it is stretched and at the same time the lifting hydraulic jack of the lift is extended (4), which is accompanied by the removal of the hinge assemblies that are placed on the rod (9) and hydraulic cylinder (10), and by turning the levers (7) and (8) in the opposite direction from the pusher (13) the direction that raises the socks (1 1), (12), and the bases (3) sink to the ground.
