Description

Technical Field

[0001] The utility model relates to the technical field of railway maintenance engineering, and more specifically to a mobile ballastless track bed concrete crushing device. Background Art

[0002] There are many types of ballastless track structures in my country, and the service environments of ballastless tracks vary greatly. During operation, it is inevitable that track structure components need to be replaced. The replacement of high-speed railway ballastless track structure components requires the dismantling of the original structure and reconstruction. In principle, the construction process is basically the same as the construction process. However, since the high-speed railway is in operation, in order to minimize the impact on driving, the line needs to be opened as soon as possible. The existing concrete crushing equipment has low breaking efficiency and occupies a large area of ​​the skylight, which can no longer meet the requirements for the replacement of ballastless track structure components.

[0003] In the replacement operation of high-speed railway ballastless track structural components, the removal of ballast bed concrete is an important link that affects the operation efficiency and skylight occupancy. At present, the main methods of removing ballast bed concrete are mechanical chiseling, hydraulic breaking and rope saw cutting. The two commonly used mechanical chiseling equipment are electric hammer and pneumatic pick. The electric hammer is driven by electricity and can be used with a generator. It is currently the most commonly used concrete breaking equipment. It uses its own weight and external forces to hammer the physical objects on the surface to achieve the purpose of crushing. The pneumatic pick is powered by compressed air and needs to be equipped with a generator and an air compressor. It is a handheld construction machine that uses impact to break hard objects. It has a compact structure and is easy to use.

[0004] Field tests have found that although high-pressure water jets can effectively protect the steel bars inside the ballast bed, their removal efficiency is low, and the ballast bed concrete needs to be removed layer by layer. Concrete chain saws are not installed in the ballast bed concrete construction in the turnout area, and the chain saws cut at high speed at the bottom of the rail, which poses a risk of damaging the rails. In contrast, traditional mechanical removal methods are more suitable for ballast bed concrete removal. Pneumatic picks need to be equipped with large air compressors for on-road construction, which is inconvenient to carry. In addition, the removal efficiency of electric picks is low.

[0005] Chiseling away the concrete on the ballast bed is a time-consuming and labor-intensive process, and is the most important step in the entire ballastless track structural component replacement process. Therefore, rapid chiseling away the concrete on the ballast bed can save more preparation time for structural component replacement.

[0006] However, in the process of replacing structural components using the above two conventional breaking equipment, it was found that it took at least 8 hours to chisel out the concrete of the roadbed around a single double-block sleeper or a single switch sleeper, which could not meet the needs of rapid replacement of damaged structural components within the 4-hour window. The hydraulic breaker is favored by the majority of users due to its low working noise and high working efficiency. At the same time, the hydraulic breaker can work under continuous extreme conditions, including underwater operations at a certain depth, cities, mountainous areas, plateaus, etc., which is unattainable by electric picks and pneumatic picks. Research results show that according to the rock fracture mechanism, under the condition of a certain hardness of rock, the working efficiency of the hydraulic breaker is higher than that of blasting construction and can replace blasting construction.

[0007] Therefore, in order to meet the needs of on-site roadbed concrete removal construction, it is urgent to design a mobile ballastless roadbed concrete crushing device based on a hydraulic breaker, which can be used for on-site roadbed concrete chiseling to further improve the roadbed chiseling efficiency.

[0049] Example:

[0050] like Figure 1 , Figure 2 As shown, the utility model is a mobile ballastless track concrete crushing device, which includes a rail running frame 10, a transverse trolley 20, a rotating frame 30, a hydraulic power station 50, a lever mechanism 60, and a hydraulic breaker 70.

[0051] The rail traveling frame 10 is installed on the upper part of the rail 90 and can move along the longitudinal direction of the rail. The transverse moving vehicle 20 is installed on the upper part of the rail traveling frame 10 and can move transversely perpendicular to the rail 90.

[0052] Specifically, Figure 3 , Figure 4As shown, the rail running frame 10 includes a flange roller 11 and a transverse guide rail 12 that rolls on the rail 90 using the flange roller 11. The transverse guide rail 12 is arranged perpendicular to the rail 90, and the upper part of the transverse guide rail 12 is provided with a guide rail groove for connecting with the lower walking guide wheel 21 of the transverse trolley 20.

[0053] Furthermore, in order to ensure the stable running of the rail running frame 10, two flanged rollers 11 are provided on the single rail 90 for corresponding rolling. The two flanged rollers are connected by a longitudinal steel, and the transverse guide rail 12 is erected and fixed on the upper part of the two longitudinal steels.

[0054] At the same time, in order to ensure the stable movement of the transverse moving trolley 20, four walking guide wheels 21 are correspondingly arranged at the lower part of the transverse moving trolley 20.

[0055] The rail traveling frame 10 of the utility model takes into account the rail running ability and insulation performance, and can be loaded with the hydraulic power station 50 and the hydraulic breaker 70 and move quickly along the line. A transverse slideway is also installed on the rail traveling frame 10, and the hydraulic power station 50 and the hydraulic breaker 70 can be loaded and moved back and forth transversely in the slideway to facilitate position adjustment, so as to crush different positions of the concrete ballast plate that needs to be crushed.

[0056] The rotating frame 30 is installed on the upper part of the transverse movement trolley 20, and is connected to the transverse movement trolley 20 through a universal mechanism 40 that can rotate horizontally and pitch up and down.

[0057] Specifically, Figure 4 , Figure 5 As shown, the universal mechanism 40 includes a vertical shaft 41 extending from top to bottom into the middle of the body 22 of the transverse moving trolley 20 and rotatably connected to the body 22, the upper end of the vertical shaft 41 is connected to a U-shaped frame 42 with an opening facing upward, the two side plates of the U-shaped frame 42 are arranged along the longitudinal direction of the rail, and a circular hole 43 is opened on the side plate of the U-shaped frame; the U-shaped frame 42 extends into the rotating frame 30, and a circular hole 43 is opened at a position corresponding to the circular hole 43 on the rotating frame 30, and a pin 32 is adapted to pass through the circular hole 43 and the circular hole 43, so as to rotatably connect the rotating frame 30 to the U-shaped frame 42.

[0058] The rotating frame 30 in the utility model can rotate horizontally around the center of the transverse movement trolley 20 with the help of the vertical axis 41 in the universal joint 40, and is further connected with the U-shaped frame 42 in the universal joint 40, so as to perform up and down pitching movements around the upper support point of the trolley center, so as to facilitate the position adjustment so as to perform crushing operations on concrete sleeper plates that need to be crushed at different positions.

[0059] The hydraulic power station 50 is installed on one side of the rotating frame 30. The lever mechanism 60 is installed on the other side of the rotating frame 30 and extends outward in a direction perpendicular to the steel rail 90. At the same time, the length of the lever mechanism 60 is adjustable.

[0060] Specifically, Figure 1 , Figure 5 As shown, the rotating frame 30 includes a connecting frame 31 with two circular holes 2 and a rectangular supporting frame 33 for supporting and fixing the hydraulic power station 50 . One end of the connecting frame 31 away from the rectangular supporting frame 33 is connected to the lever mechanism 60 .

[0061] Furthermore, the lever mechanism 60 includes an outer tube 61, an inner tube 62 and a locking pin. One end of the outer tube 61 is connected to the rotating frame 30, and the inner tube 62 is arranged in the tube cavity of the other end. The inner tube 62 can slide relative to the outer tube 61; a plurality of connecting holes 1 are axially opened on the outer tube 61, and a connecting hole 2 is opened on the inner tube 62. The locking pin passes through the connecting hole 1 and the connecting hole 2 which are aligned up and down to realize the length adjustment of the lever mechanism 60.

[0062] Furthermore, in order to ensure a firm connection, a rib plate 63 is vertically fixed at the connection node between the outer tube 61 and the rotating frame 30 .

[0063] like Figure 1 , Figure 7 As shown, the hydraulic breaker 70 is vertically arranged and connected to the end of the lever mechanism 60 away from the rotating frame 30, that is, the distal end of the inner tube 62, through the universal hinged mounting frame 80. The hydraulic breaker 70 is connected to the hydraulic power station 50 by a hydraulic hose and a quick connector, and the hydraulic power station 50 provides hydraulic power for the hydraulic breaker 70.

[0064] The utility model adopts hydraulic power technology. The hydraulic power station 50 drives the crushing drill rod hammer component on the hydraulic breaker 70. After the crushing drill rod hammer component is aimed at the concrete rail sleeper plate to be crushed, the concrete is knocked by hammering, which can quickly and efficiently crush the roadbed plate concrete, and gradually crush the concrete through powerful impact energy.

[0065] One end of the lever mechanism 60 in the utility model is the hydraulic breaker 70, and the other end is the hydraulic power station 50 as a counterweight. By adjusting the length of the lever, the counterweights at both ends of the hydraulic power station 50 and the hydraulic breaker 70 are balanced. For example, if the weight ratio of the hydraulic power station 50 to the hydraulic breaker 70 is 4:1, the length of the lever is adjusted to a corresponding ratio of 1:4. In this way, when the hydraulic breaker 70 is carried, the actions of lifting, lowering, moving angles, pressing down, etc. are all very light.

[0067] The universal articulated mounting frame 80 allows the head of the hydraulic breaker 70 to freely rotate the crushing angle, so that during the crushing operation, the crushing head can be rotated at any angle as needed and the center of gravity of the crushing head can be maintained, making the operation stable and easy.

[0068] In the utility model, the hydraulic breaker is used to break the concrete of the roadbed slab. It is installed on the lever mechanism and is used to directly hit the concrete to break it after the concrete position is aligned. Moreover, the hydraulic breaker can be adapted to be installed with any one of the pointed breaking drill rod, the flat breaking drill rod and the chisel breaking drill rod. The utility model increases the types of corresponding breaking drill rods in the hydraulic breaker for selection, so that it can adapt to more breaking conditions.

[0069] It should be noted that the hydraulic breaker used in the utility model is generally a small hydraulic breaker, which belongs to the existing equipment. For details, please refer to the corresponding hydraulic breaker disclosed in the utility model patent with authorization announcement number CN201874570U.

[0070] In the utility model, the rail running frame and the transverse trolley, the transverse trolley and the rotating frame, the rotating frame and the hydraulic power station, and the lever mechanism and the hydraulic breaker are all connected in a detachable manner, so that the device of the utility model can be decomposed into multiple pieces within the window point and transported and installed on the line, achieving high-efficiency concrete crushing and meeting the need for rapid replacement of damaged switch sleepers within the 4-hour window time.

[0071] After the prototype of the utility model was completed, various tests were conducted in the internal site for operational flexibility, diversity of crushing angles, actual effect of crushing impact work, etc. The test results met the expected requirements. The various mechanisms in the device can be disassembled and transported to the site, quickly assembled and placed on the line, the hydraulic breaker can quickly travel to the working position, and can use almost any angle to fully crush the line bottom plate concrete, with high crushing efficiency and high precision, and the impact work is 3 to 4 times that of the electric pick, the operator consumes less physical energy, the construction intensity is low, the trial effect is good, and it can meet the needs of on-site application.
