(54) ДВУХКАТКОВАЯ МОНОРЕЛЬСОВАЯ ТЕЛЕЖКА(54) TWO-CART MONORAIL TRUCK

II

Изобретеш1е относитс к подъемно-транспортному машиностроению, а именно к двухкатковым монорельсовым тележкам электроталей.The invention relates to a lifting and transport machinery, in particular to two-roll monorail trolleys of electric hoists.

Известны двухкатковые монорельсовые тележки, содержащие катки, св занные с заключенными в корпус редукторами, соединенными между собой проставкой и кинематически св занными валом, и двигатель, укрепленный на корпусе одного из редукторов 1).Dvuhkatkovye monorail trolleys are known, containing rollers connected with gearboxes enclosed in a housing, interconnected by a spacer and kinematically connected shaft, and an engine mounted on the housing of one of the gearboxes 1).

Однако эти тележки имеют такие недостатки как необходимость высокой точности изготовлени редукторов и проставки, возможность возникновени перекоса соединительного вала от внешних нагрузок, его поломки и выхода из стро зубчатых колес редуктора, низка технологичность конструкции предохранительных элементов.However, these trolleys have such disadvantages as the need for high precision manufacturing of gearboxes and spacers, the possibility of a misalignment of the connecting shaft from external loads, its breakage and breakage of the gears of the gearbox, low manufacturability of the design of safety elements.

Целью изобретени вл етс повышение технологичности изготовлени тележки и упрощени ее монтажа.The aim of the invention is to improve the manufacturability of the cart and simplify its installation.

Поставленна цель достигаетс в результате того, что проставка выполнена из соединенных между собой щек, в каждой из которых имеетс центрирующий элемент, в котором размещен вал, кинематически св зывающий редукторы , корпусы которых смонтированы на щеках проставки.The goal is achieved as a result of the fact that the spacer is made of interconnected cheeks, each of which has a centering element in which is placed a shaft that kinematically connects gearboxes whose shells are mounted on the spacer cheeks.

На фиг. 1 показана предлагаема тележка; на фиг. 2 разрез А фиг. 1; на фиг. 3 разрез фиг. 2; на фиг. 4 - то же, вариант выполнени ; на фиг. 5 - узел Т фиг. 1.FIG. 1 shows the proposed trolley; in fig. 2 a section A of FIG. one; in fig. 3 a section of FIG. 2; in fig. 4 - the same, the embodiment; in fig. 5 - node T of FIG. one.

Двухкаткова монорельсова тележка содержит левый и правый редукторы 1 и 2, соединенные между собой проСтавкой, состо щей из двух щек 3 и 4, св занных поперечиной 5. В каждой щеке выполнен центрирующий элемент , представл ющий, собой кольцевой выступ 6. Выступы выполнены соосно один другому и размещены соответственно в корпусах редукторов 1 и 2.A two-wheeled monorail cart contains left and right gearboxes 1 and 2 interconnected by an extension consisting of two cheeks 3 and 4 connected by a cross member 5. Each cheek has a centering element, which is an annular protrusion 6. The projections are made coaxially one different and are located respectively in the gearbox housing 1 and 2.

Claims

The motor 7 is attached to the gearbox housing 2, the cranking moment from which the gears B, 9, 10, I, 12 and 13 is transmitted to the running rollers 14 and 15. The torque from the gearbox 2 to the gearbox 1 is transmitted by the shaft 16 placed in annular ledges 6 cheeks 3 and 4 spacers. The housing 38 of each gearbox is fastened respectively to the cheeks 3 and 4 spacers with bolts 17, 18, 19. The gears of each gearbox are attached to the console in the wall of its gearbox. The gearboxes 1 and 2 are covered with lids 20 and 21 and have 1 shafts 22 and 23 in which guide rollers 24 and 25 are installed. To ensure the trolley passes along curvilinear paths of small radius in the middle part of the cross member 5, a vertical opening 26 is made, in which the pin 27 is placed, having in the upper part a horizontal opening 28, through which the yoke 29 passes, carrying the load-lifting mechanism 30. To increase the safety of the work of the trolley on the cheeks 3 and 4 of the spacer, safety elements-clamps are provided, executed in the form of appl 31 (fig. 3); in the embodiment, the bolt 19 is made elongated, and it itself performs the role of pickup (Fig. 4). The centering element can be made in the form of a sleeve 32 (Fig. 5) installed in the cheek 3 (respectively, and in the cheek 4) of the spacer and gearbox housing 1 (respectively, also in the gearbox housing 2). Monorail trolley works as follows. The torque from the engine 7 is transmitted through the gears and the connecting shaft 16 to the rollers 14 and 15, whereby the trolley is set in motion. The mutual displacements of the gearboxes 1 and 2 in the vertical plane do not reflect on the transmission work, since the presence of circular coaxially arranged ribs 6 through which the shaft 16 passes allows centering the gears. The spacer can be practically made of plastic npoimoro material, for example steel. Gearbox housings can be made of ShP1 aluminum cast iron, i.e. fragile materials and relatively less durable than spacer material. In the event of failure of the gearbox housing under the action of the support reaction to the roller, the trolley is loaded with safety elements (clamps) and tides 31 or elongated parts of the bolts 19, thereby eliminating the fall of the lifting machine (electric hoist) and load. The part of the reducer that is broken off cannot be stored, since it will be confined to the steel lid that covers the gearbox cavity. All this will increase the reliability of the cart. The presence of centering elements in the spacer and the separate mounting of gearbox housings to the spacer minimizes the number of high-precision parts, simplifies the process of manufacturing the trolley, as well as its installation at the place of operation. Claim 1. A two-roll monorail trolley containing rollers connected to gearboxes harnessed to the housing, interconnected by a spacer and kinematically connected shaft, and an engine mounted on the housing of one of the gearboxes, characterized in that, in order to increase the manufacturability of the carriage and simplification of its Montahs, the spacer is made of interconnected cheeks, each of which has a centering element in which a shaft is placed, kinematically connecting gearboxes, the cases of which are mounted Ovans cheeks spacers.

2. Trolley according to claim 1, characterized in that the centering element is designed as an annular protrusion fixed on the cheek and located in the gearbox housing.

3. Trolley according to claim. characterized in that the centering element is made of a sleeve disposed in the cheek and in the gearbox housing. Sources of information taken into account during the examination 1. Electric hoist type ТЭ1. Installation and operation manual, M., p. 18, fig. eleven.
