Vibrating device for cleaning gondola cars

Description

[0001] Technical field

[0002] The proposed utility model relates to railway transport, namely to devices that make it possible to facilitate and speed up the process of cleaning gondola cars from bulk cargo, in particular crushed stone, by means of vibratory action on the gondola car body.

[0003] Technology Level

[0004] The prior art includes numerous vibratory machines designed to facilitate and accelerate the process of unloading bulk cargo from gondola cars. The primary idea behind the development of this utility model was to create a device capable of powering the vibratory plate's electric motor from the electrical circuit of the crane involved in this process.

[0005] A "Mounted Vibratory Machine for Unloading Bulk Cargo from Gondola Cars" is known. A disadvantage of this invention is the use of a belt drive for the vibration exciter, which, when operating outdoors at sub-zero temperatures, can lead to belt breakage and, consequently, the inoperability of the entire system. In this invention, the center of gravity and the vibration exciter are located above the gondola car's frame, which reduces the intensity of the vibration wave, as the impact is uniform in all directions. This is a disadvantage compared to the claimed utility model, in which the vibration exciter is located below the top frame of the gondola car, allowing the vibration wave to act exclusively on the side walls of the gondola car.Another disadvantage is the placement of the fixing points of the lifting devices (hooks, slings, cables) in only two places, in close proximity to the center of the invention, which does not allow for the minimization of oscillatory and rotational movements during the lifting of the device and its installation on the gondola car, while in the claimed utility model such places are located at the outermost four points on the support beams, which reduces the “harmful” movements of the device during its lifting and installation, and therefore reduces the time of such operations. RU 2094353 B65G 67 / 24 (1995.01).

[0006] Also known as the "Overhead Vibration Machine." The design drawbacks of this device include its complex construction, which includes two centrifugal exciters with shafts and unbalance weights, requiring a specialized double-ended electric motor. The large number of structural components increases production costs, increases weight, and reduces the overall reliability of the unit. The electric motor's power supply method is also not specified, although the claimed utility model requires power from the crane's electrical circuit. RU 2811192 B65G 67 / 24 (2000.01).

[0007] The closest solution in terms of the supporting frame design is the "Supply-Mounted Vibratory Machine for Unloading Bulk Cargo from Gondola Cars." A disadvantage of this invention is its complex design, which, in addition to the frame, includes a self-synchronizing dual-shaft vibration exciter with multiple electric motors and reaction masses equipped with strikers and anvils. This increases manufacturing costs, increases the weight of the structure, and reduces operational reliability due to the increased number of moving parts. Disadvantages of this invention relative to the claimed utility model also include the lack of structural elements that allow the device to be secured to the edges of the gondola car's upper frame. The claimed utility model, however, includes grooves and stops corresponding to the width of the gondola car wall, ensuring fixation to the gondola car walls and facilitating and speeding up the installation of the vibratory device.The method for powering the electric motors is not specified in the materials. However, the stated advantage of the claimed utility model is the technical feasibility of powering the vibratory plate drive electric motor from the crane's on-board electrical system. Another disadvantage is the mounting locations for the lifting mechanisms, which are offset toward the center of the structure, preventing the reduction of vibrations and rotation of the structure during lifting and installation of the device on a gondola car. In contrast, in the claimed utility model, such locations are located at the four outermost points on the support beams, which reduces the "harmful" movements of the device during lifting and installation, and therefore reduces the time of such operations. RU 2181688 C2 B65G 67 / 24 (2000.01).

[0008] The invention "Resonance vibrating machine for unloading bulk cargo from gondola cars" is also known from the existing prior art. Like the previously considered devices, it contains an excessive number of elements that complicate and increase the cost of the design, in particular 2 vibration exciters, 4 inertial masses, which is the main disadvantage with respect to the claimed utility model. Another disadvantage is the location and method of transmitting vibrations along the upper parts of the side walls, by acting on their ends, which leads to more rapid attenuation of the pulse as the wave passes towards the bottom of the walls, and the bottom of the car in which the unloading hatches are located. RU 2160222 C1 B65G 67 / 24, B65G 69 / 20 (2000.01).

[0009] The technical problem, which the claimed utility model is aimed at solving, is the creation of a universal device of a simplified design that facilitates and accelerates the process of cleaning gondola cars from bulk cargo, in particular crushed stone, by vibrating the walls of the gondola car body, with the possibility of powering the drive electric motor of the vibratory plate from the on-board network of the crane in order to reduce the number of workers involved in the technological process.

[0010] Disclosure of the essence of the utility model.

[0011] The technical result is achieved due to the fact that the vibrating device for cleaning gondola cars, containing a rectangular supporting frame formed by longitudinal, transverse and diagonal beams, some of which perform a reinforcing role, also having two parallel support beams in its upper plane, made with the possibility of transmitting the vibration effect to the walls of the gondola car, which, extending beyond the dimensions of the frame, form together with it an H-shaped structure in plan, and connecting at each of its ends with its lower plane by stiffening ribs, form a trapezoidal structure in profile, 2 platforms in the upper and lower planes of the frame, a vibrating plate and an electric motor, characterized in that the said support beams have grooves-stops at each of the ends corresponding to the width of the gondola car wall, made with the possibility of fixing the device on the upper strapping of the gondola car, the ends of each of the support beams also contain brackets,designed with the possibility of fastening hooks of lifting mechanisms and devices, creating a symmetrical arrangement with a maximum distance from the center of the structure, the lower plane of the frame contains a rigidly fixed vibration plate, in the body of which a shaft with unbalances is installed through bearing supports, the drive of the unbalances is carried out from an electric motor through a cardan shaft, the electric motor is mounted on a platform located on the upper plane of the frame and offset relative to the center of the device, thereby creating a combination of the axis of the electric motor shaft with the drive of the unbalances, on one of the walls of the platform a power socket is fixed, made with the possibility of supplying power to the electric motor from the on-board circuit of the crane.

[0017] Implementation of a utility model

[0018] A vibrating device for cleaning gondola cars comprises a rectangular supporting frame formed by longitudinal, transverse and diagonal beams, some of which perform a reinforcing role, also having two parallel support beams in its upper plane, providing the transmission of vibration action to the walls of the gondola car, which, extending beyond the dimensions of the frame, form together with it an H-shaped structure in plan, and, connecting at each of its ends with its lower plane by stiffening ribs, form a trapezoidal structure in profile, 2 platforms in the upper and lower planes of the frame, a vibrating plate and an electric motor, characterized in that the said support beams have grooves-stops at each of the ends corresponding to the width of the gondola car wall, providing fixation of the device on the upper strapping of the gondola car, facilitating and accelerating the process of installing the vibrating device, the ends of each of the beams also contain brackets,providing the possibility of fastening the hooks of lifting mechanisms and devices, such a symmetrical arrangement with the maximum distance from the center of the structure allows to reduce the amplitude of swinging and rotation of the device around its axis when it is installed on a gondola car before bringing it into the working position, the lower plane of the frame contains a rigidly fixed vibration plate, in the body of which a shaft with unbalances is installed through bearing supports, the drive of the unbalances is carried out from the electric motor through the cardan shaft, the electric motor is mounted on a platform located on the upper plane of the frame and offset from the center of the device, thereby ensuring the alignment of the axis of the electric motor shaft with the drive of the unbalances, a power socket is fixed on one of the walls of the platform, providing the possibility of supplying power to the electric motor from the on-board circuit of the crane.

[0019] The vibratory device for cleaning gondola cars operates as follows. A KZhDE-16 railway crane is used to place the vibratory device on the car body. To power the crane, an electric cable is first run from its on-board power supply along the boom, connecting to a power outlet near the hook. This power outlet is connected to the power outlet on the vibratory device before work begins. After securing the slings to the loops on the vibratory device's support beams and to the crane hook, the vibratory device is placed on the gondola car's upper frame, securing it in place with grooved stops. When the electric motor is turned on, rotational energy is transferred through the cardan shaft to the vibratory plate, driving the shaft with the unbalance weights.The vibrations created are transmitted to the car body via support beams, spreading across the entire plane of the side walls and the bottom of the car; they are transmitted to the cargo, destroying the connections between its individual elements and allowing it to be unloaded through the open lower hatches of the gondola cars due to gravity.

[0020] Previously, before the introduction of the vibratory device, cleaning gondola cars after crushed stone unloading required seven people to clean 14 gondola cars per shift, loosening frozen and compacted crushed stone with hand tools. Using the vibratory device and a crane frees up five people, and two people are required for the final cleaning of the gondola car bottom from dust and individual crushed stone particles. Powered by the crane, external power sources and power cable monitoring are eliminated.

[0021] Made of recycled materials: channel (140 mm and 80 mm profile), vibratory plate - 1 pc., DC electric motor - 1 pc., power socket 1 pc.
