Description

Technical Field

[0001] This utility model relates to the field of railway track construction, specifically to a rapid excavation device for railway track construction. Background Technology

[0002] The ballast filling machine is a specialized piece of equipment used in railway maintenance to fill ballast in the core area. It improves construction efficiency and track stability through mechanized operation. Its working principle is based on an electric motor-driven transmission system, which drives the ballast hook to complete the process of ballast picking, conveying and filling. The speed control and stable operation are achieved through a self-locking component. Therefore, the ballast filling machine is often used for ballast filling operations after track laying.

[0003] In actual use, existing ballast repair machines directly dump the stones inside the ballast hook by flipping it. Since the ballast hook is at its highest point when it flips, most of the stones will concentrate below the flipping point when dumping. However, the flipping point of the existing ballast repair machine is only on one side of the track, which means that the stones cannot be dumped in the middle of the two tracks, resulting in poor ballast repair effect. Utility Model Content

[0004] Based on the above description, this utility model provides a rapid excavation device for railway track construction to solve the problem that existing ballast filling machines cannot dump stones in the middle of the track.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A rapid excavation device for railway track construction includes a frame, an electric motor installed on the top of the frame, a flexible shaft installed at the output end of the electric motor, a first reducer installed at the end of the flexible shaft away from the electric motor, a pulley installed at the output end of the first reducer, a transmission belt installed on the surface of the pulley, a ballast hook installed on the surface of the transmission belt, and a pulley installed at the bottom of the frame. The pulley is connected to the output end of the electric motor through a second reducer. A slide rail is installed on the top of the frame, a guide block is installed at the bottom of the slide rail, and a push block is installed at the bottom of the guide block; The slide has a triangular cross-section, and both the left and right sides of the slide have sloping surfaces. Baffles are installed on the side walls of the slopes on both the left and right sides of the slide. When the ballast hook moves to its highest point, it is located above the left slope of the slide.

[0006] Furthermore, mounting grooves are provided on the front and rear sides of the slide, and a slider is movably connected to the inner wall of the mounting groove. A connecting rod is fixedly connected to the end of the slider away from the mounting groove, and the end of the connecting rod away from the slider is fixedly connected to the side of the guide block.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, there are two of each of the mounting slots, sliders, and connecting rods, which are symmetrically distributed on the front and rear sides of the slide.

[0009] Furthermore, one end of the guide block is designed to be inclined, and the lower end of the slope on the left side of the slide is located above the inclined surface of the guide block.

[0010] Furthermore, one end of the guide block is movably connected to a threaded rod via a bearing, and a fixing plate is fixedly installed at the bottom of the slide, with the threaded rod threaded through the fixing plate.

[0011] Furthermore, fixing rods are fixedly installed on both the front and rear sides of the slide, and the end of the fixing rod away from the slide is fixedly connected to the frame.

[0012] Furthermore, one side of the push block has a groove, and the push block is trapezoidal in shape when viewed from below, with the groove located on the inclined side of the push block.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: 1. This utility model sets a slide on the frame so that the stones falling from the ballast hook can slide down the slide. With the guidance of the guide block, the stones fall into the middle area of ​​the two tracks. At the same time, the guide block is adjustable. The threaded rod can be turned to move the guide block according to the actual use needs, so that the guide block can guide the stones to fall into the middle area of ​​the two tracks more accurately.

[0014] 2. By installing a pusher block below the guide block, the movement of the entire device drives the pusher block to move together, which pushes the stones apart and disperses the stones that have fallen to the ground, preventing the stones from being too concentrated. At the same time, grooves are made on the pusher block, which allows the stones to be pushed along the concave surface of the grooves to the middle area of ​​the track, achieving the effect of the stones being in the middle area of ​​the track.

[0019] It is understood that spatial relation terms such as "below," "under," "below," "below," "above," "above," etc., can be used here to describe the relationship between one element or feature shown in the figure and other elements or features. It should be understood that, in addition to the orientation shown in the figure, spatial relation terms also include different orientations of the device in use and operation. For example, if the device in the figure is flipped, the element or feature described as "below" or "below" of the other element or feature will be oriented "above" the other element or feature. Therefore, the exemplary terms "below" and "below" can include both upper and lower orientations. Furthermore, the device may also include other orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptive terms used herein will be interpreted accordingly.

[0020] It should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the technical product is in use. They are used only for the convenience of describing the technology and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the technology. Furthermore, "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. Therefore, the terms "first," "second," "third," etc., are used only for distinguishing descriptions and should not be construed as indicating or implying relative importance. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0021] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted.

[0023] Please see Figure 1 , Figure 2 and Figure 3 A rapid excavation device for railway track construction includes a frame 1, an electric motor 2 mounted on the top of the frame 1, a flexible shaft 3 mounted on the output end of the electric motor 2, a first reducer 4 mounted on the end of the flexible shaft 3 away from the electric motor 2, a pulley 5 mounted on the output end of the first reducer 4, a transmission belt 6 mounted on the surface of the pulley 5, and a ballast hook 7 mounted on the surface of the transmission belt 6. The ballast hook 7 moves in the direction of rotation of the transmission belt 6. When it reaches the end of the transmission belt 6, it flips over, which will dump the stones in the ballast hook 7. A pulley 9 is mounted on the bottom of the frame 1. The pulley 9 is connected to the output end of the electric motor 2 through a second reducer, a transmission gear, and a transmission shaft. A slide 8 is installed on the top of the frame 1, a guide block 84 is installed at the bottom of the slide 8, and a push block 10 is installed at the bottom of the guide block 84. When the ballast hook 7 is flipped, the stone will fall from the ballast hook 7, fall onto the slide 8, slide onto the guide block 84, and finally fall from the guide block 84 into the space between the two tracks. The slide 8 has a triangular cross-section and inclined slopes on both sides. The stones will slide down the inclined slopes onto the guide block 84. Baffles are installed on the side walls of the slopes on both sides of the slide 8 to limit the sliding stones and prevent them from sliding down the sides of the slide 8. When the ballast hook 7 is moved to its highest point, it is located above the left slope of the slide 8, which makes it easy to ensure that the stones fall onto the left slope when it is flipped. The stones can slide down the left slope onto the guide block 84 and then slide down from the guide block 84 into the track. Compared with falling directly from the flipped ballast hook 7, the stones can get closer to the middle area of ​​the track.

[0024] Please see Figure 3 and Figure 4 In this embodiment, the slide 8 has mounting grooves 81 on both the front and rear sides. A slider 82 is movably connected to the inner wall of the mounting groove 81. A connecting rod 83 is fixedly connected to the end of the slider 82 away from the mounting groove 81. The end of the connecting rod 83 away from the slider 82 is fixedly connected to the side of the guide block 84.

[0025] Please see Figure 3 and Figure 4 In this embodiment, there are two mounting slots 81, two sliders 82, and two connecting rods 83. The two mounting slots 81, two sliders 82, and two connecting rods 83 are symmetrically distributed on the front and rear sides of the slide rail 8. The symmetrically distributed connecting rods 83 can ensure the stability of the guide block 84.

[0026] Please see Figure 1 In this embodiment, one end of the guide block 84 is designed to be inclined, and the lower end of the slope on the left side of the slide 8 is located above the inclined surface of the guide block 84, so that the stones sliding down from the left slope of the slide 8 can slide from the inclined surface of the guide block 84 into the middle area of ​​the track.

[0027] Please see Figure 3 and Figure 4 In this embodiment, one end of the guide block 84 is movably connected to a threaded rod 85 via a bearing, and a fixing plate 86 is fixedly installed at the bottom of the slide rail 8, with the threaded rod 85 threaded through the fixing plate 86.

[0028] Tighten the threaded rod 85 to push the guide block 84 to move. At this time, the slider 82 will slide in the mounting groove 81, thereby adjusting the position of the guide block 84. The position of the guide block 84 can be adjusted according to the actual use, so that the stone can slide from the guide block 84 and get closer to the middle area of ​​the track. Please see Figure 3 and Figure 4 In this embodiment, fixing rods 87 are fixedly installed on the front and rear sides of the slide 8. The end of the fixing rod 87 away from the slide 8 is fixedly connected to the frame 1. The fixing rod 87 is used to fix the slide 8.

[0029] Please see Figure 1 and Figure 3 In this embodiment, the push block 10 has a groove 11 on one side, and the push block 10 is trapezoidal in shape when viewed from below. The groove 11 is located on the inclined side of the push block 10. When the device is in use, the pulley 9 on the frame 1 is placed on the track, and then the motor 2 is started to drive the pulley 9 to move on the track. At this time, the push block 10 will push the stone away from the push block 10, and the pushed stone will be pushed away from the inclined concave surface of the groove 11 in the direction away from the push block 10, that is, the middle area of ​​the two tracks.
