Description

Technical Field

[0001] This utility model belongs to the field of slipform concrete paving construction technology, and in particular relates to a leveling device for slipform concrete paving construction. Background Technology

[0002] A slipform paver is a type of equipment used for paving concrete. Unlike manual concrete paving, slipform pavers are more efficient, have a larger paving surface, and produce more uniform concrete. Therefore, slipform pavers are widely used in industry.

[0003] For example, slipform pavers can be used for paving operations on slopes, enabling efficient paving on challenging slopes. After the concrete is paved, it needs to be compacted by rollers, and then smoothed.

[0004] Currently, the compaction of paved concrete by roller is mostly carried out on horizontally set roads, specifically by manually pulling the rollers to compact the concrete.

[0005] Slope work presents significant challenges. When the roller is placed on a slope, its own weight can cause it to slip down, preventing it from smoothly rolling over the concrete structure. Furthermore, this is especially true for wide slopes. After the slipform paver has initially spread the concrete, the increased width makes manual rolling operations even more difficult. In actual construction, the length of the paved concrete road is often considerable, resulting in a large total area requiring roller compaction. Clearly, rolling and smoothing large areas of concrete on slopes is both labor-intensive and inefficient.

[0006] Therefore, in actual work, the efficiency of slope paving operations can be greatly improved by using an automated roller pressing and smoothing device in conjunction with a slipform paver. Utility Model Content

[0007] Based on the above background, the purpose of this utility model is to provide a leveling device for slipform concrete paving construction.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A leveling device for slipform concrete paving construction includes a paving roller leveling mechanism for leveling concrete slopes. The paving roller leveling mechanism includes an inclined leveling frame, on which a plurality of leveling rollers are assembled and connected.

[0010] The paving roller leveling mechanism also includes tracks spaced at intervals, and the upper and lower ends of the leveling frame are respectively fixedly connected to a drive structure that supports rolling on the tracks. The drive structure includes a motor and a support wheel installed on the output end of the motor, and the support wheel supports rolling on the top of the track.

[0011] The leveling frame is equipped with concrete smoothing mechanisms at both ends. The concrete spread by the slipform paver is smoothed by the concrete smoothing mechanism.

[0012] Preferably, a pair of leveling rollers spaced apart are rotatably connected inside the leveling frame;

[0013] One end of the leveling roller is driven by a drive motor.

[0014] Preferably, a lower end frame is fixedly connected to the lower end of the leveling frame;

[0015] The upper end of the leveling frame is fixedly connected to an upper end frame, and the motors in the drive structure are fixedly installed on the upper end frame and the lower end frame respectively.

[0016] The drive motor is fixedly mounted on the lower end frame.

[0017] Preferably, the track includes a track base portion, the top of which is integrally formed with a protruding track protrusion, and the track protrusion has a limiting wheel groove for limiting and supporting the track wheel.

[0018] Preferably, the bottom of the upper frame is fixedly connected to an upper support roller structure that supports the upper support rollers that roll on the track base. The upper support roller structure includes a wheel frame seat fixedly connected to the bottom of the upper frame, and a plurality of upper support rollers are rotatably connected to the wheel frame seat. The upper support rollers roll on the track base.

[0019] Preferably, a plurality of lower support wheels are rotatably connected to the lower end frame, and the lower support wheels support the rolling motion at the top position of the track base.

[0020] Preferably, the concrete smoothing mechanism includes a long rotating shaft rotatably connected to the side of the leveling frame, a smoothing plate fixedly connected to the long rotating shaft, and a smoothing motor for driving the long rotating shaft to rotate installed on the leveling frame.

[0021] Preferably, the upper and lower ends of the leveling frame are integrally formed with protruding bosses on both sides, and the long rotating shaft is rotatably connected between the bosses.

[0022] Preferably, the outer end of the squeegee plate has an integrally formed squeegee portion.

[0023] This utility model has the following beneficial effects:

[0024] 1. During the working process, under the drive of the motor, the support rail wheel is limited to rolling in the limiting wheel groove on the rail protrusion. Furthermore, under the drive of the drive motor, the leveling roller rolls the paved concrete. Because the support rail wheel is rolled, the roller moves automatically during the rolling process, which greatly improves the efficiency of leveling and rolling concrete.

[0025] 2. The stability of the entire device's rolling movement is increased by using upper and lower support rollers.

[0026] 3. During the working process, the sizing plate is rotated to a specific angle by the sizing motor, and the sizing part contacts the concrete structure layer, continuously smoothing the concrete as the entire device moves. This method achieves simultaneous smoothing of the concrete structure during roller pressing and leveling, further improving construction efficiency. Furthermore, because the angle and posture of the sizing plate are adjustable, the pressure intensity of the sizing part on the concrete can be adjusted, thereby improving smoothing efficiency.

[0037] Example 1

[0038] like Figure 1-5 As shown, a leveling device for slipform paving concrete construction includes a paving roller leveling mechanism 2 for leveling concrete slopes. The paving roller leveling mechanism 2 performs roller leveling on the concrete structure paved by the slipform paver on the slope. This allows for coordinated operation with the slipform paver, overcoming the technical shortcomings of difficult and inefficient slope operations.

[0039] The specific structure of the paving roller leveling mechanism 2 is as follows:

[0040] The paving roller leveling mechanism includes an inclined leveling frame 21 (with a rectangular cross-section, made of welded steel frame), on which a pair of leveling rollers 22 are mounted and connected at intervals; the bottom of the leveling rollers 22 protrudes from the bottom of the leveling frame 21.

[0041] Furthermore, the lower end of each leveling roller 22 is driven by a drive motor 23 (similar to existing methods, the upper and lower ends of the leveling roller 22 are fixedly mounted with rotating shafts, which are rotatably connected to the leveling frame 21, and correspondingly, suitable bearings are installed on the leveling frame 21). The output shaft of the drive motor 23 is fixedly mounted on the rotating shaft via a coupling.

[0042] Meanwhile, in order to achieve automatic roller compaction and leveling, the above-mentioned paving roller compaction and leveling mechanism also includes upper and lower rails 1 spaced apart. That is, during construction, the upper and lower rails 1 are fixedly installed at the top and bottom of the slope respectively, according to the existing method. The structure of the rail 1 is as follows: the rail 1 includes a rail base, the top of which is integrally formed with a protruding rail protrusion (the longitudinal interface shape is T-shaped), and the rail protrusion has a limiting wheel groove for limiting the following support rail wheel 32.

[0043] Meanwhile, in order to achieve automatic walking roller pressing, the upper and lower ends of the above-mentioned leveling frame 21 are respectively fixedly connected with a drive structure 3 that supports rolling on the track 1. The drive structure 3 includes a motor 31 and a support wheel 32 installed on the output end (output shaft) of the motor 31. The support wheel 32 supports rolling on the top of the track 1 (a limiting wheel groove is provided on the protrusion of the track 1 to limit the support wheel 32).

[0044] Specifically, a lower end frame 5 is fixedly connected to the lower end of the leveling frame 21; similarly, an upper end frame 6 is fixedly connected to the upper end of the leveling frame 21. The lower end frame 5 and the upper end frame 6 are fixed to the leveling frame 21 by welding, and the lower end frame 5 and the upper end frame 6 are irregularly shaped structures.

[0045] Meanwhile, the motors in the aforementioned drive structure 3 are fixedly mounted on the upper frame 6 and the lower frame 5, respectively. Furthermore, the drive motor 23 (driving the leveling roller 22) is fixedly mounted on the lower frame 5.

[0046] During operation, under the drive of the motor, the support wheel 32 is limited to rolling in the limiting wheel groove on the protrusion of the track 1. Under the drive of the drive motor 23, the leveling roller 22 rolls the paved concrete. Because the support wheel 32 is rolled, the roller moves automatically during the rolling process, which greatly improves the efficiency of the leveling roller 22 in rolling concrete.

[0047] Example 2

[0048] like Figure 1-5 As shown, in this embodiment, based on the structure of Embodiment 1, the bottom of the upper frame 6 is fixedly connected to an upper support roller structure that supports the rollers rolling on the base of the track 1. The upper support roller structure includes a wheel frame seat 71 (the longitudinal cross-sectional shape of the wheel frame seat 71 is L-shaped and welded to the bottom of the upper frame 6) fixedly connected to the wheel frame seat 71. Several upper support rollers 72 are rotatably connected to the wheel frame seat 71, and the upper support rollers 72 roll on the base of the track 1. This method increases stability during rolling movement.

[0049] Similarly, several lower support wheels 33 are rotatably connected to the lower end frame 5. The lower support wheels 33 support the rolling motion at the top position of the base of the track 1 (the lower support wheels 33 are rotatably connected to axles, which are fixedly installed on the lower end frame 5). With the assistance of the lower support wheels 3333 and the upper support rollers 72, the stability of the rolling movement of the entire device is increased.

[0050] Example 3

[0051] like Figure 1-5 As shown, in this embodiment, based on the structure of embodiment 2, in order to achieve the smoothing of concrete during the roller pressing process, concrete smoothing mechanisms are installed at both ends of the leveling frame 21. The concrete spread by the slipform paver is smoothed by the concrete smoothing mechanism.

[0052] Specifically, the concrete smoothing mechanism includes a long rotating shaft 42 rotatably connected to the side of the leveling frame 21 (the upper and lower ends of the leveling frame 21 are integrally formed with protruding bosses on both sides, and the long rotating shaft 42 is rotatably connected between the bosses; according to the existing method, bearings are installed on the bosses). A smoothing plate 43 is fixedly connected to the long rotating shaft 42, and a smoothing motor 41 that drives the long rotating shaft 42 to rotate is installed on the leveling frame 21 (similarly, the smoothing motor 41 is fixedly installed on the lower end frame 5).

[0053] The outer end of the aforementioned screed plate 43 is integrally formed with a smoothing section. The smoothing section is located at the bottom of the outer end of the screed plate 43 and is in a sloping state. During operation, the screed plate 43 is driven to rotate to a specific angle by the smoothing motor 41, and the smoothing section abuts against the concrete structure layer and moves with the entire device to continuously smooth the concrete.

[0054] This method enables simultaneous smoothing of the concrete structure during the roller pressing and leveling process, further improving construction efficiency. Furthermore, the adjustable angle of the 43° trowel allows for adjustable pressure intensity of the troweled portion on the concrete, further enhancing smoothing efficiency.

[0055] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
