Description

Technical Field

[0001] The utility model relates to the technical field of rail grinding vehicles, and particularly relates to a dust collection hopper for a rail grinding vehicle. Background Technique

[0002] With the rapid development of the railway transportation industry, the maintenance work of rails has become increasingly important. The rail grinding vehicle can repair the surface damage of the rails and eliminate the unevenness of the rail surface by grinding the rail surface, so as to ensure the safety and smoothness of train operation. However, during the grinding operation, a large amount of impurities such as metal chips and dust will be generated. If these impurities are not collected in time, they will not only float in the working environment, threatening the physical health of the staff, but also may enter the mechanical transmission parts, electrical components and other parts of the grinding vehicle, causing equipment failures, shortening the service life of the equipment, increasing the maintenance cost, and at the same time polluting the surrounding ecological environment.

[0003] For example, a Chinese patent with the application number 202020090792.7 discloses a dust collection hopper for a rail grinding vehicle, belonging to the technical field of rail grinding vehicles, which solves the problem that when the existing dust collection hoppers are used together by splicing, there are gaps between the dust collection hoppers, resulting in easy dust accumulation. The technical solution adopted by this dust collection hopper for a rail grinding vehicle is as follows: the dust collection hopper for a rail grinding vehicle includes a bottom plate and side plates connected to the four sides of the bottom plate. The bottom plate and the side plates form a dust collection cavity with an open top. At least one of the two opposite side plates is provided with a concave platform, and the concave platform protrudes towards the dust collection cavity. The concave platform directly forms a handle groove or a handle is arranged in the concave platform, and the thickness of the handle is not greater than the depth of the concave platform. By adopting the above structure, when the dust collection hoppers are used together by splicing, the gaps between the dust collection hoppers are very small, and the residual amount of dust between the gaps of the dust collection hoppers can be significantly reduced. For example, four dust collection hoppers are placed in a "field" shape in the rail grinding vehicle, which can avoid forming gaps at the splicing points and reduce dust accumulation. The utility model is applicable to the dust removal system of rail grinding vehicles.

[0004] However, when cleaning this dust collection hopper for a rail grinding vehicle, the staff needs to manually open the dust collection hopper and re-introduce the internal impurities into the collection bag.

[0021] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1-4 As shown, this utility model provides a technical solution: including a dust collection hopper assembly 1, wherein the bottom end of the dust collection hopper assembly 1 is provided with a push-out flipping assembly 2;

[0023] The dust collection hopper assembly 1 includes a dust collection hopper body 101. The top of the dust collection hopper body 101 is provided with a U-shaped dust collection bag mouth cover 103. The bottom surface of the U-shaped dust collection bag mouth cover 103 is provided with a nesting groove 104. The U-shaped dust collection bag mouth cover 103 is movably fitted onto the top opening of the dust collection hopper body 101 through the nesting groove 104.

[0024] The push-out flipping assembly 2 includes a first linear motor 201. A mounting plate 202 is fixedly installed on the top of the slider of the first linear motor 201. A stepped groove is opened on one side of the top surface of the mounting plate 202. A second linear motor 203 is fixedly installed on the rear part of the bottom surface of the stepped groove. A toothed plate 204 is fixedly installed on the top surface of the slider of the second linear motor 203. Adapter plates 205 are fixedly installed on both sides of the rear part of the top surface of the mounting plate 202. A rotating shaft 206 is rotatably installed between the two adapter plates 205. A flipping plate 208 is fixedly sleeved on the shaft of the rotating shaft 206.

[0025] In this embodiment, two fixing threaded holes 102 are provided on the top of the front and back sides of the dust collection hopper body 101, and fixing mounting ears 105 are fixedly installed on the front and back of the bottom of the U-shaped dust collection bag mouth cover 103.

[0026] Meanwhile, each of the four fixed mounting ears 105 has a fixing bolt 106 threaded into the middle of its outer side. The four fixing bolts 106 correspond one-to-one with the four fixing threaded holes 102. One end of the fixing bolt 106 is threaded into the fixing threaded hole 102. By screwing one end of the fixing bolt 106 into the fixing threaded hole 102, a stable connection can be achieved between the U-shaped dust collection bag opening cover 103 and the dust collection hopper body 101. When it is necessary to inspect or replace the dust collection bag, the fixing bolts 106 can be removed for easy separation, which facilitates operation inside the dust collection hopper.

[0027] One end of the shaft of the rotating shaft 206 extends to the outside of the adapter plate 205 provided on one side, and a rotating gear 207 is fixedly sleeved on the extended end of the rotating shaft 206. The rotating gear 207 meshes with the toothed plate 204.

[0028] Both sides of the top front of the mounting plate 202 are fixedly installed with pads 209, which serve to support and stabilize the mounting plate 202.

[0029] The dust collection hopper body 101 is fixedly installed on the top surface of the flip plate 208.

[0030] Based on the structural layout of the rail grinding vehicle, a suitable installation location was selected. High-strength bolts were used to firmly fix the No. 1 linear motor 201 to the vehicle frame, ensuring accurate installation orientation, parallel and unbiased running track, and smooth motor operation.

[0031] Remove the dust collection bag and place it inside the dust collection hopper body 101. Then, expand the top opening of the dust collection bag and fit it over the opening of the dust collection hopper body 101. Next, install the U-shaped dust collection bag opening cover 103. The U-shaped dust collection bag opening cover 103 is movably fitted onto the top opening of the dust collection hopper body 101 through the nesting groove 104, so that the fixing mounting ear 105 is aligned with the fixing threaded hole 102 on the dust collection hopper body 101. Then, insert the fixing bolt 106 into the fixing threaded hole 102 and tighten it to ensure that the U-shaped dust collection bag opening cover 103 is tightly connected to the dust collection hopper body 101 without looseness or gaps. The top opening of the dust collection bag is pressed down by the U-shaped dust collection bag opening cover 103, and then impurities can be conveniently discharged directly into the dust collection bag without having to repeatedly import the dust and impurities collected in the dust collection hopper body 101 back into the dust collection bag, reducing the secondary dust collection steps, avoiding dust dispersion, and reducing the difficulty of recycling.

[0032] When the impurities collected in the dust collection hopper reach a certain amount and need to be cleaned, the operator starts the first linear motor 201 through the control system. The slider of the first linear motor 201 drives the mounting plate 202 and the dust collection hopper assembly 1 to be smoothly pushed outward along the linear track, moving the dust collection hopper to a position outside the vehicle body that is easy to clean. After the dust collection hopper is pushed out to the position, the second linear motor 203 is started. The slider of the second linear motor 203 drives the toothed plate 204 to move. The toothed plate 204 meshes with the rotating gear 207, driving the rotating shaft 206 to rotate, which in turn drives the tilting plate 208 and the dust collection hopper body 101 to tilt, emptying the dust collection bag in the dust collection hopper body 101 into the designated collection container. There is no need to manually remove the dust collection bag from the dust collection hopper body 101. During the cleaning process, the pad 209 always supports the mounting plate 202 to ensure the stability of the dust collection hopper during the tilting process.

[0033] After the impurities are emptied, reverse the operation of linear motor 201 and linear motor 203 to restore the dust collection hopper assembly 1 to a vertical state. Then, use linear motor 201 to retract the dust collection hopper to its initial position. Next, remove the fixing bolts 106, remove the U-shaped dust collection bag cap 103, and install a new dust collection bag inside the dust collection hopper body 101. Then, prepare for the next dust collection operation.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
