Description

The invention relates to devices for lifting and closing hatch covers of gondola cars. According to the main author. St. No. 802112, a device for closing hatch covers of gondola cars is known, comprising a frame mounted parallel to a railway track, on which a hitch lifter configured as a lever connected to an output shaft of a drive reducer, a crank-connecting rod mechanism is mounted, which can be rotated in a vertical and horizontal plane; mounted between the output shaft of the gearbox and the lever and pivotally connected with them, the connecting rod of the mechanism being made of two parts spring-loaded one relative to the other, and the lever is made once We have a shoulder and a short arm connected to a crank connecting rod (tunnel mechanism 1). However, an efficient device is unreliable due to the fact that when the hatch covers are closed (the hatch cover is 25 °) the device lever sometimes touches the design elements of the undercarriage the gondola, leading to damage to the lockbox itself and to the deterioration of the gondola cars.Therefore, a very precise activation of the device’s electric motor is required, which is very difficult, since the composition of the gondola cars moves at a speed of 3 km / h. And when closing the middle hatches (their opening angle is up to 33 °), in some cases the lever does not grab the hatch cover (they are often bent) and passes into the space of the hatch, which also leads to device breakage. The purpose of the invention is to increase the reliability of the device. To achieve this goal, a device for closing hatch covers of gondola cars, comprising a frame mounted parallel to the railway track, on which a hatch lifter, made in the form of a lever connected to the output shaft of the drive reducer, is mounted, crank-and-connecting rod mounted on the vertical and horizontal planes a mechanism mounted between the gearbox output shaft and the lever and pivotally connected to them, the mechanism crank being made of two parts spring-loaded one relative to the other; the lever is made It is raznoplechim and its short arm is connected to the crank rod crank mechanism, equipped with a ski for interacting with the gondola trolleys, connected by a lever spring lever to the razgulim lever mechanism. Equipping the device with a ski allows you to automatically change the length of the equal-arm lever depending on the at the moment, the middle or supra-hatching hatch, which increases the reliability of the device by eliminating its breakdown and increases the speed of pulling the composition of gondola cars from 3 to 5 km / h FIG. 1 shows the device, front view in FIG. 2 - the same, top view; in FIG. 3, view A in FIG. one; in fig. 4 - crank positions during device operation; in fig. 5 - connecting rod; in fig. 6 is a view B in FIG. 1 in the off position; in fig. 7 - the same, in the working position, (closing the middle hatches); in fig. 8 - the same, in the position under the undercarriage (closing of the carts); in fig. 9 is a view of B in FIG. 7 The device consists of a frame 1 on which the gearbox 2 is mounted, the high-speed shaft 3 of which is connected with the help of the sleeve-and-pin coupling 4 with the electric motor 5. On the low-speed (output) shaft 6 of the gearbox is mounted a crank-crank mechanism consisting of the crank 7 and the connecting rod 8 It is connected to a double-arm lever 9, the long end of which serves to lift the hatch covers 10.1, 10.2 gondola cars and has the ability to rotate in the vertical and horizontal planes. The connecting rod 8 (Fig. 5) is made up of parts G and D and is equipped with a spring L, serving to maintain the lever in the upper position for 0.8-1 s, as well as to compensate for the lever force depending on the location of the bottom of the gondola car. The electric motor of the device is equipped with an electro-hydraulic brake shoe 12. The device is equipped with a ski 13 connected by means of a lever-spring mechanism 14 with a ratchet arm 9 for lifting hatch covers of gondola cars. The ski is fixed in the working position by the pin 15. The ski has the opportunity to occupy three positions (Fig. 6-9) 1st position (non-working) - horizontal, beyond the dimensions of the approach of buildings. The length of the lever is of size N. At this time, shunting operations with gondola cars in any direction can be made. 2nd position (working) - vertical The device is prepared for closing the hatch covers of gondola cars. The length is of the size I. In this position, the middle hatches 10.1 can be closed when removing the gondola cars from the unloading front at a speed of no more than 5 km / h. 3rd position - under the undercarriage of the gondola. The length of the lever is size N. The device is prepared to close the carriage hatches 10.2. The movement of cars is only possible in the direction of withdrawal of empty cars from the unloading front. The operation of the device for closing the gondola composition is carried out as follows. Before starting work on closing the hatches, the ski 13 must be brought into the working (vertical) position, fixing it with pin 15. When the first gondola approaches with the open hatches to the device, the first drive car 16 of the gondola interacts with the ski 13 and the retractor. The force from the ski through the lever-spring mechanism 14 is transmitted to the lever 9, which deviates from the vertical position, by 40-45 ° in the direction opposite to the thrust of the cars (Fig. 8). At the same time, the length of the lever for lifting the hatch covers is reduced to the size I, which allows the hatch covers of the hatches to be closed, without affecting the design elements of the undercarriage carriages (Fig. 9). At the approach of the second and all subsequent, their sublend hatches (depending on the pt of the gondola car), the operation of closing the hatches is repeated. After closing the hatches, middle hatches are suitable for the device. The ski 13 of the device ceases to interact with the undercarriage of the gondola and under the action of the mass of the lever 9 through the lever-spring mechanism 14, it returns to the vertical initial position. Lever 9 takes upright position. Its length has increased to the size of I. The device is prepared for closing medium hatches. The middle hatches of the gondola cars are closed. When approaching the device of hatchels located above the second undercarriage of the gondola, the device’s operation is similar to the work of closing the manhole covers over the first undercarriage. Then the cycle repeats. Upon completion of the closing of the hatch covers of the entire gondola composition, the ski 13 is moved to a non-operating horizontal position beyond the envelope of the buildings. In comparison with the known, the proposed device provides an increase in the speed of pulling the composition of gondola cars, as a result of which labor productivity increases.
