Description

Technical Field

[0001] This utility model belongs to the field of structural design, specifically relating to a ventilation and dust removal device that can be installed on a railway flatcar. Background Technology

[0002] Large road maintenance machinery, such as screening machines, generates a large amount of dust during screening operations. This dust permeates the area around the machine, obstructing the operator's vision and harming their health. If operations are conducted inside tunnels, the existing dust in the air combined with the dust generated during the operation can cause a significant drop in engine power or even damage to the vehicle in a short period of time.

[0003] Currently, the existing ventilation and dust removal equipment used in railways mainly consists of two sets of interconnected devices, each with ventilation and dust removal capabilities, mounted centrally on a dedicated railway flatcar. The operating principle is as follows: the ventilation and dust removal device is installed on the flatcar and travels in conjunction with a large track maintenance machinery cleaning vehicle. Before operation, a spray system is used to spray water 2-3 times on the ballast working surfaces on both sides of the rails at the work site to eliminate the large amount of dust generated during the cleaning of the ballast by the cleaning vehicle. Secondly, when working in tunnels, water is sprayed first, and then the device is placed at the tunnel entrance, using jet fan components to suck or blow away dust, thereby eliminating existing dust inside the tunnel and dust generated during the cleaning operation. The dust removal effect increases with the length of the tunnel, requiring more devices.

[0004] The existing ventilation and dust removal system mainly consists of six parts: a water storage tank, a jet fan assembly, a spray system, a generator, an operation control console, and a dedicated fixing assembly. The first five parts are mounted on a road flatbed truck via the sixth part, a dedicated fixing assembly, to prevent the equipment from tipping over or rolling over when the flatbed truck is running at high speed.

[0005] The existing equipment has several main problems. First, the fixing components of the ventilation and dust removal device have safety shortcomings. Specifically, the fixing components securing the five parts of the equipment on the flatbed truck are not connected, failing to form a unified whole and lacking overall tension. This causes the equipment to tip over due to the inertia generated when the flatbed truck is running at high speeds. Second, the connection between the jet fan assembly, the water tank, and the truck body is achieved by welding the equipment directly to the truss, which is then welded to the ground of the flatbed truck. This makes disassembly extremely difficult during maintenance, and the repeatedly damaged truss cannot be reused. Furthermore, disassembling the welds also damages the equipment, resulting in waste. These issues urgently need to be addressed. Second, the spray system of the device is ineffective. This system consists of a water tank located on the flatbed truck, with the spray pipes connected to the tank and then mounted under the truck. First, the existing equipment uses holes drilled in steel pipes to spray water using natural water pressure, but the pressure is insufficient and the water coverage does not meet the requirements. Second, water often flows back through the holes and sprays onto the wheels and bogies of the flatbed truck, interfering with wheel rotation and posing a safety hazard to the vehicle. This problem must be eliminated. Utility Model Content

[0006] The purpose of this utility model is to provide a ventilation and dust removal device that can be installed on a railway flatcar, so as to overcome the shortcomings of existing equipment in the prior art, such as poor fixing effect on flatcars and poor effect of spraying and watering devices.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A ventilation and dust removal device that can be installed on a railway flatcar includes a spraying and watering device. The spraying and watering device includes a water storage tank, which is fixed to one side of the flatcar. A jet fan assembly is installed on the water storage tank. The water storage tank is connected to the flatcar and the jet fan assembly through a fixing component. The fixing component includes multiple crossbeams, multiple longitudinal beams, and a bottom beam. The longitudinal beams are evenly fixed on the bottom beam, and the crossbeams are arranged perpendicular to the longitudinal beams to form multiple U-shaped structures. Fastening components are provided on both sides of the base.

[0009] Furthermore, the fixing component also includes a T-shaped component. The bottom of the water storage tank is provided with two rows of I-beams. The T-shaped component includes a horizontal part and a vertical part. When fixing, the horizontal part of the T-shaped component abuts against the I-beams, and the lower part of the vertical part connects to the horizontal beam, so that the water storage tank is fixed to the horizontal beam.

[0010] Furthermore, a base is provided on the bottom beam, and the base is fixedly connected to the longitudinal beam by base fastening bolts.

[0011] Furthermore, a height adjustment pad is provided between the bottom beam and the base.

[0012] Furthermore, the fastening component includes a crimp fastener with a column hole sleeved on it. One end of the crimp fastener is provided with a fastening bolt for fixed connection to the bottom beam, and the other end is provided with a column hole limiting plate with a column hole fixing bolt.

[0013] Furthermore, one end of the crimp fastener is equipped with a fastening bolt and a height adjustment pad for fixed connection, and the other end is equipped with a column hole limiting plate and a column hole fixing bolt is provided on the column hole limiting plate.

[0014] Furthermore, the sprinkler system also includes a generator, a water pump, a motor, water pipes, and nozzles; the generator, water tank, water pump, motor, water pipes, and nozzles are connected in sequence.

[0015] Furthermore, there are multiple nozzles, and the nozzles are arranged in a horizontally staggered manner, perpendicular to the direction of the track and respectively aligned with the ballast positions on both sides of the rail.

[0016] Furthermore, the generator is connected to an operating console.

[0017] Furthermore, the water pump is equipped with an overload protector.

[0018] Compared with the prior art, the present invention has the following beneficial technical effects:

[0019] This utility model provides a ventilation and dust removal device that can be installed on railway flatcars. The fixing components feature a modular design, facilitating easy assembly and disassembly, and allowing for reuse, thus saving costs. Multiple crossbeams, longitudinal beams, and a bottom beam are staggered to form multiple U-shaped structures, securing the jet fan assembly and water tank. This effectively distributes the weight of the water tank and jet fan assembly, ensuring a secure installation on the flatcar, unaffected by the bumps during railway transport, and greatly reducing the risk of malfunctions due to loosening. Fastening components on both sides of the base ensure a reliable connection between the water tank and the flatcar. This design makes installation more convenient and allows for easy disassembly or adjustment of the device's position, enhancing its flexibility. The structure and connection method of the fixing components allow it to adapt to various types of railway flatcars, reducing installation difficulty and cost, improving the device's versatility, and providing an effective ventilation and dust removal solution for different railway transportation scenarios.

[0020] Specifically, the fixing components include T-shaped parts that work in conjunction with the I-beams at the bottom of the water tank to further reinforce the connection between the water tank and the crossbeams.

[0021] Specifically, a base is installed on the bottom beam, and a height adjustment pad is installed between the bottom beam and the base. During the actual installation process, the staff can flexibly adjust the height of the entire device by increasing or decreasing the number of height adjustment pads or replacing the adjustment pads with different thicknesses, according to the different structures of the flatbed car and the specific needs of the installation site, so as to ensure the accuracy and stability of the device installation and make it adaptable to various types of railway flatbed cars.

[0022] Specifically, an overload protector was added to the water pump in the sprinkler system to prevent the pump from burning out due to overload. The method of drilling holes in the steel pipe for water spraying was replaced with a nozzle-based system. Drilling holes in the steel pipe before installing the nozzles directly eliminates the safety hazard of water backflow damaging the equipment. The nozzles are arranged in a staggered pattern to ensure full coverage of the work area, effectively expanding the water spray range. Furthermore, the high-pressure water mist effectively suppresses dust, saving water and improving dust suppression. Attached Figure Description

[0029] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0030] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0031] See Figure 1 and Figure 2 This utility model provides a ventilation and dust removal device that can be installed on a railway flatcar, including a spraying and watering device. The spraying and watering device includes a water storage tank 2, which is fixed to one side of the flatcar 1. A jet fan assembly 3 is installed on the water storage tank 2. The water storage tank 2 is connected to the flatcar 1 and the jet fan assembly 3 through a fixing component. The fixing component includes multiple crossbeams 4, multiple longitudinal beams 5, and a bottom beam 9. The bottom beam 9 serves as a foundation, and multiple longitudinal beams 5 are evenly fixed on the bottom beam 9. A base 10 is installed on the bottom beam 9, and the base 10 is fixedly connected to the longitudinal beams 5 by base fastening bolts 11. The base 10 provides longitudinal support for the entire fixing component. The crossbeams 4 and longitudinal beams 5 are arranged perpendicularly and intersect each other to form multiple U-shaped structures. Fastening components 6 are provided on both sides of the base 9. The upper part of this fixing component can fix the jet fan assembly 3, the middle part spans the water storage tank 2 to prevent it from swaying, and the fastening part 6 provided on the base 9 fixes the base 9 to the flatbed 1. Through the force transmission of the mechanical structure, the jet fan assembly 3 and the water storage tank 2 are fixed to the flatbed 1.

[0032] To ensure that the water tank 2 and the jet fan assembly 3 do not tip over during the movement of the flatbed trolley 1, the water tank 2 is further secured to the fixing components, see [reference needed]. Figure 3The fixing assembly also includes a T-shaped component 7. Two rows of I-beams 8 are provided at the bottom of the water tank 2. The T-shaped component 7 includes a horizontal part 7-1 and a vertical part 7-2. During the fixing operation, the horizontal part 7-1 of the T-shaped component 7 tightly abuts against the I-beams 8. By utilizing the large contact area and friction between the two, the horizontal displacement of the water tank 2 is effectively prevented. The lower part of the vertical part 7-2 is firmly connected to the horizontal beam 4 by welding, bolting or other means, so as to stably transfer the weight of the water tank 2 to the horizontal beam 4, thereby achieving reliable fixing of the water tank 2 and the horizontal beam 4, and further enhancing the stability of the entire ventilation and dust removal device.

[0033] Preferred options, please refer to Figure 4 The fastening component 6 includes a crimp fastener 12, which is fitted with a column hole 23. One end of the crimp fastener 12 is provided with a fastening bolt 14 and is fixedly connected to the bottom beam 9. The other end is provided with a column hole limiting plate 13, and the column hole limiting plate 13 is provided with a column hole fixing bolt 15. During installation and fixing, align the recess of the crimp fastener 12 with the connection between the bottom beam 9 and the flatbed 1, pass the fastening bolt 14 through the corresponding hole of the crimp fastener 12, and make a tight threaded connection with the bottom beam 9. By tightening the bolt, the crimp fastener 12 and the bottom beam 9 are firmly fixed together, ensuring the stable installation of the entire fastening component on the bottom beam 9. Then tighten the column hole fixing bolt 15 to make the column hole limiting plate 13 and the column hole 23 in close contact, so that the bottom beam 9 and the flatbed 1 are tightly fixed together, realizing a stable and reliable connection between the water tank 2 and the flatbed 1. This ensures the stability of the ventilation and dust removal device when running on the railway flatbed, and can effectively prevent the water tank 2 from loosening or shifting even in complex railway transportation environments.

[0034] Preferably, the height adjustment pad 22 provided between the bottom beam 9 and the base 10 is made of a material with certain strength and wear resistance, such as rubber or metal pads. During actual installation, workers can flexibly adjust the height of the entire device by increasing or decreasing the number of height adjustment pads 22 or replacing them with pads of different thicknesses, according to the different structures of the flatbed car 1 and the specific needs of the installation site. This ensures the accuracy and stability of the device installation and allows it to adapt to various types of railway flatbed cars.

[0035] Preferably, in the existing technology, the sprinkler system uses holes drilled in steel pipes to spray water using natural water pressure. However, the pressure is insufficient and the water coverage is inadequate. Secondly, water often flows back through the holes and sprays onto the wheel bogies of the flatbed truck, interfering with wheel rotation and posing a safety hazard. Therefore, the sprinkler system needs improvement. (See reference...) Figure 5The sprinkler system also includes a generator 16, a water pump 17, a motor 21, a water pipe 18, and sprinkler heads 19. The generator 16, water tank 2, water pump 17, motor 21, water pipe 18, and sprinkler heads 19 are connected sequentially. Multiple sprinkler heads 19 are arranged laterally in a staggered manner, perpendicular to the track direction and aligned with the ballast on both sides of the rail. The water pump 17 draws water from the water tank 2 and delivers it to each sprinkler head 19 through the water pipe 18. The motor 21 may be used to assist in controlling the water flow rate or the direction of the sprinkler heads 19. Because the sprinkler heads 19 are arranged laterally in a staggered manner, perpendicular to the track direction and aligned with the ballast on both sides of the rail, water sprayed from the sprinkler heads 19 can be evenly distributed onto the ballast, thus wetting the ballast and preventing dust from being stirred up. The water pump 17 is equipped with an overload protector, which can cut off the power supply in time when the water pump 17 is abnormally overloaded, protect the motor of the water pump 17 from damage, extend the service life of the equipment, and also avoid safety hazards caused by equipment failure. The generator 16 is connected to the control panel 20, which makes it convenient for operators to monitor and control the operating status of the entire device.

[0036] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
