Description

Technical Field

[0001] This application relates to the field of road construction technology, and in particular to a leveling device for roadbed slope construction. Background Technology

[0002] A leveling device for roadbed slope construction in highway engineering is a type of mechanical equipment specifically used in road and bridge construction to level roadbed slopes. Its main function is to use mechanical means to trim roadbed slopes to achieve the required flatness and slope, thereby ensuring the stability of the roadbed and the quality of construction.

[0003] However, existing leveling devices for roadbed slope construction have the following disadvantages: the tilt angle of traditional leveling devices is fixed and difficult to adjust, and different slopes have different leveling requirements, which limits the devices and makes them difficult to apply to slopes with different angles; and the overall compaction of the soil is low after leveling the slope, which reduces the stability of the slope.

[0004] Therefore, there is an urgent need for a leveling device for roadbed slope construction to solve the above problems. Utility Model Content

[0005] This application provides a leveling device for roadbed slope construction, which aims to ensure applicability to slope construction environments with different angles, while improving the stability and flatness of the slope.

[0006] To achieve the above objectives, this application provides the following technical solutions:

[0007] A leveling device for roadbed slope construction includes a frame and the angle adjustment component;

[0008] The frame of the U-shaped structure is inclined, and the angle of inclination of the frame is consistent with the slope angle of the side slope;

[0009] The angle adjustment component is rotatably mounted at one end of the frame;

[0010] The angle adjustment assembly includes a base frame, two connecting plates, two limiting rods, at least two limiting sliders, a pressure plate, and a leveling assembly.

[0011] The bottom frame is horizontally positioned on the lower surface of the slope, and one end of the bottom frame is rotatably connected to the bottom end of the frame body;

[0012] One end of each of the two connecting plates is fixedly connected to the two ends of the bottom frame near the frame body, and the circumferential surface of the other end is rotatably engaged with the bottom two ends of the frame body.

[0013] The two limiting rods pass horizontally through the corresponding connecting plates and are rotatably connected to the bottom ends of the frame.

[0014] The pressure plate is horizontally positioned on one side of the frame, with the side of the pressure plate away from the frame abutting against the slope surface.

[0015] The leveling component is disposed on one side of the frame relative to the pressure plate, and the working surface of the leveling component abuts against the slope.

[0016] Furthermore, through grooves are provided at both ends of the bottom of the frame along its thickness direction, the opening of the through grooves faces one side of the bottom frame, and the groove wall of the through groove slides in contact with the circumferential surface of the corresponding connecting plate.

[0017] Furthermore, the leveling assembly includes two mounting plates, two connecting plates, two screws, two connecting blocks, a pressure cylinder, and two fixing rods;

[0018] The two mounting plates are horizontally and symmetrically arranged on one side of the frame opposite to the pressure plate;

[0019] The bottom of the groove of the connecting plate with the two groove-shaped structure is fixedly connected to the corresponding mounting plate;

[0020] The two screws pass vertically through the corresponding connecting plates and are fixedly connected to the corresponding mounting plates;

[0021] One end of each of the two connecting blocks extends into the groove of the corresponding connecting plate, and the other end extends away from the connecting plate.

[0022] The circumferential surface of the pressure cylinder is fixedly connected to the end of the two connecting blocks away from the connecting plate;

[0023] The two fixing rods pass through the groove width direction of the corresponding connecting plate and are rotatably connected to the periphery of the corresponding connecting block.

[0024] Furthermore, the pressure plate has a flange on the side away from the frame, and the length direction of the flange is set at an acute angle to the length direction of the pressure plate.

[0025] Furthermore, at least two connecting rods are provided between the pressure plate and the frame, and at least two limiting grooves are provided on the side of the frame near the pressure plate along its height direction, with one end of the two connecting rods abutting against the groove wall of the corresponding limiting groove.

[0026] Furthermore, reinforcing rods are provided at equal intervals along the length of the inner side of the frame.

[0027] In this application, the U-shaped frame is tilted at the same angle as the slope, ensuring initial stable contact. When the slope angle changes, the bottom ends of the frame can rotate around the limiting rods to adapt. The pressure plate is horizontally positioned on one side of the frame, with its end furthest from the frame abutting the slope surface. This design prevents excessive shaking or deviation of the frame during operation, ensuring precise operation of the leveling component and distributing pressure on the slope to avoid localized damage. The leveling component is positioned on the side of the frame opposite the pressure plate, with its working surface abutting the slope. As the device moves along the slope, the leveling component uses its working surface to smooth the slope, removing excess soil or uneven areas, achieving the designed flatness and slope.

[0036] like Figures 1 to 4 As shown, a leveling device for roadbed slope construction includes a frame 1 and an angle adjustment component 2. The frame 1, with a U-shaped structure, is inclined, and the inclination angle of the frame 1 is consistent with the slope angle. The angle adjustment component 2 is rotatably mounted on one end of the frame 1. The angle adjustment component 2 includes a bottom frame 203, two connecting plates 202, two limiting rods 201, at least two limiting sliders, a pressure plate 206, and a leveling component 3. The bottom frame 203 is horizontally mounted on the lower surface of the slope, and one end of the bottom frame 203 is rotatably connected to the bottom end of the frame 1. One end of the connecting plate 202 is fixedly connected to the two ends of the bottom frame 203 near the frame 1, and the circumferential surface of the other end is rotatably engaged with the two bottom ends of the frame 1; the two limiting rods 201 pass horizontally through the corresponding connecting plates 202 and are rotatably connected to the two bottom ends of the frame 1; the pressure plate 206 is horizontally disposed on one side of the frame 1, and the side of the pressure plate 206 away from the frame 1 is in contact with the slope surface; the leveling component 3 is disposed on the side of the frame 1 opposite to the pressure plate 206, and the working surface of the leveling component 3 abuts against the slope.

[0037] In the above scheme, the frame 1 with a U-shaped structure is tilted, and its tilt angle is consistent with the slope angle, so that the device is in stable contact with the slope in the initial state. When the slope angle changes, the two ends of the bottom of the frame 1 can rotate around the limiting rod 201 to adapt to slopes with different angles. The pressure plate 206 is horizontally set on one side of the frame 1, and the side of the pressure plate 206 away from the frame 1 is in contact with the slope surface. The purpose of this setting is to ensure that the frame 1 will not shake excessively or deviate from the predetermined position due to external forces during operation, and to ensure that the leveling component 3 can accurately work along the slope. At the same time, the contact between the pressure plate 206 and the slope surface also helps to disperse the pressure of the device on the slope and avoid excessive local pressure that could damage the slope. The leveling component 3 is set on the side of the frame 1 opposite to the pressure plate 206, and the working surface of the leveling component 3 is in contact with the slope. As the device moves along the slope, the leveling component 3 uses its working surface to trim the slope, removing excess soil or uneven parts, so that the slope reaches the design requirements for flatness and slope.

[0038] The bottom ends of the frame 1 are provided with through grooves 101 along its thickness direction. The opening of the through groove 101 faces the side of the bottom frame 203, and the groove wall of the through groove 101 slides in contact with the circumferential surface of the corresponding connecting plate 202.

[0039] In the above scheme, when the frame 1 needs to adjust its tilt angle to adapt to slopes of different angles, the connecting plate 202 will slide relative to the frame 1 along its thickness direction within the through groove 101. For example, when the slope angle increases and the tilt angle of the frame 1 needs to be increased, the frame 1 rotates around its rotational connection point with the bottom frame 203 to adapt to the change in the angle of the frame 1. At the same time, the rotational cooperation between the connecting plate 202 and the frame 1 and the bottom frame 203 ensures the stability and continuity of the entire structure during the angle adjustment process.

[0040] The leveling assembly 3 includes two mounting plates 301, two connecting plates 302, two screws 303, two connecting blocks 305, a pressure cylinder 306, and two fixing rods 304. The two mounting plates 301 are horizontally symmetrically arranged on one side of the frame 1 opposite to the pressure plate 206. The bottom of the grooves of the two groove-shaped connecting plates 302 are fixedly connected to the corresponding mounting plates 301. The two screws 303 pass vertically through the corresponding connecting plates 302 and are fixedly connected to the corresponding mounting plates 301. One end of the two connecting blocks 305 extends into the groove cavity of the corresponding connecting plate 302, and the other end extends away from the connecting plate 302. The circumferential surface of the pressure cylinder 306 is fixedly connected to the end of the two connecting blocks 305 away from the connecting plate 302. The two fixing rods 304 pass through the groove width direction of the corresponding connecting plate 302 and are rotatably connected to the circumference of the corresponding connecting block 305.

[0041] In the above scheme, the two mounting plates 301 are horizontally symmetrically arranged, and the pressure cylinder 306 is fixedly connected to the two connecting blocks 305, so that the pressure cylinder 306 can maintain a relatively stable movement trajectory and pressure distribution during operation, thereby ensuring the uniformity of the leveling operation. When the device performs roadbed slope leveling operation, the frame 1 moves along the slope, driving the leveling component 3 to move as a whole. Since the pressure cylinder 306 is fixedly connected to the connecting blocks 305, and the connecting blocks 305 are rotatably connected to the connecting plate 302 through the fixing rod 304, the pressure cylinder 306 can roll on the slope surface with the movement of the device. At the same time, due to the fixing effect of the screw 303 on the connecting plate 302, the pressure cylinder 306 can compact and level the slope surface with appropriate pressure and angle, removing the uneven parts of the slope surface, so that the slope reaches the design requirements for flatness and slope.

[0042] The pressure plate 206 has a flange 2061 on the side away from the frame 1, and the length direction of the flange 2061 is set at an acute angle to the length direction of the pressure plate 206.

[0043] In the above scheme, when the leveling device moves along the slope to perform its operation, the flange 2061 will first come into contact with the slope surface. Since the flange 2061 and the pressure plate 206 form an acute angle along their length, this arrangement allows the flange 2061 to make contact with the slope soil in a "cutting" manner when it comes into contact with the slope, further compacting the soil and reducing soil loosening and slippage.

[0044] At least two connecting rods 205 are provided between the pressure plate 206 and the frame 1. At least two limiting grooves 204 are provided on one side of the frame 1 near the pressure plate 206 along its height direction. One end of the two connecting rods 205 abuts against the groove wall of the corresponding limiting groove 204.

[0045] In the above scheme, the limiting groove 204 is set along the height direction of the frame 1, providing clear guidance for the movement of the connecting rod 205. When the angle of the frame 1 is adjusted or the device moves on the slope, the connecting rod 205 will move accordingly along the direction of the limiting groove 204, ensuring that the pressure plate 206 can always be in contact with the slope surface in a predetermined direction and trajectory. At the same time, the limiting groove 204 constrains the range of motion of the connecting rod 205, preventing the connecting rod 205 from excessively deviating or leaving the normal working position during movement, ensuring the safety and stability of the device within the normal working range.

[0046] The inner side of the frame 1 is provided with reinforcing rods 102 at equal intervals along its length.

[0047] In the above scheme, the purpose of setting the reinforcing rod 102 is to improve the modal strength of the frame 1, so that the frame 1 can withstand greater external forces without deformation or damage. At the same time, it reduces the stress concentration around the frame 1 and reduces fatigue damage caused by long-term stress on the frame 1.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
