Description

Technical Field

[0001] The utility model relates to tunnel concrete construction equipment, in particular to a concrete paving and leveling device. Background Art

[0002] Tunnel construction is an important project in infrastructure construction, in which concrete pouring, as a key process, directly affects the quality and progress of the project. However, the existing concrete pouring technology has several shortcomings, mainly reflected in the complexity of the construction process, low work efficiency, and the difficulty of project quality assurance. In addition, the application degree of existing technologies in mechanization and automation is still insufficient, which limits the further improvement of construction efficiency and quality. In tunnel construction, paving and leveling machines are introduced to replace traditional manual vibration and leveling operations. Although this type of equipment has reduced the intensity of manual labor to a certain extent, its leveling effect is not ideal. Existing paving and leveling machines often adopt the method of vibrating and walking during operation, but due to the limited working range of the vibrating device and the fast initial setting speed of concrete, the vibration is insufficient, which affects the construction quality and progress. For example, the Chinese patent document with publication number CN112855210A discloses a concrete vibrating paving and leveling device, including a frame, a vibrating mechanism, a lifting and adjusting mechanism, and a paving and leveling mechanism, wherein the vibrating mechanism is composed of a vibrating rod, a vibrating driving member, a vibrating rod guide member, and a vibrating trolley, wherein the vibrating rod is connected to the vibrating driving member and reciprocates through the vibrating trolley. However, in this technology, the movement of the vibrating rod during operation is limited to the vertical direction, resulting in a limited effective range of vibration conduction, low vibration efficiency, and a long time consumption, which is not conducive to the rapid progress of large-scale construction operations.

[0026] Figures 1 to 6 An embodiment of the concrete paving and leveling device of the utility model is shown. The concrete paving and leveling device of this embodiment includes a paving and leveling mechanism 3, a vibrating assembly 4, a guide rail 11 arranged on the pier 1, and a running frame 2 arranged on the guide rail 11. The running frame 2 is provided with a first lifting mechanism 6 for driving the vibrating assembly 4 to rise and fall, a swinging driving mechanism 5 for driving the vibrating assembly 4 to swing, and a second lifting mechanism 7 for driving the paving and leveling mechanism 3 to rise and fall.

[0027] In the concrete paving and leveling device of this embodiment, the vibrating assembly 4 can swing under the drive of the swing drive mechanism 5, so that the vibrating assembly 4 can contact a larger range of concrete through the swing, and the first lifting mechanism 6 can drive the vibrating assembly 4 to rise and fall, so as to achieve full-depth vibration of the concrete, which significantly expands the effective vibration range of the vibrating assembly 4, improves the density of the concrete, and overcomes the problem of uneven concrete vibration caused by the limited vibration range of traditional vibrating equipment. When not working, the vibrating assembly 4 can be folded and stored by swinging to reduce the limited space occupied in the tunnel. The concrete paving and leveling device of this embodiment has a wide vibration range, good paving and leveling effect, a high degree of mechanization, reduced manual participation, and high paving and leveling work efficiency.

[0028] See Figure 1 , Figure 3 and Figure 6Furthermore, in this embodiment, guide rails 11 are provided on both sides of the trestle 1, and the running frame 2 includes two guide rails 11, which are respectively arranged one by one with the two guide rails 11. The guide rails 11 can provide guidance for the running frame 2 to prevent the running frame 2 from deflecting when running, and the structure is simple and effective; a crossbeam 8 is provided between the two running frames 2 (wherein the transverse direction is the width direction of the tunnel, and the longitudinal direction is the length direction of the tunnel), and a plurality of vibrating assemblies 4 are provided and arranged at intervals along the length direction of the crossbeam 8. The crossbeam 8 is provided between the two running frames 2, which enhances the stability of the vibrating assemblies 4 when moving, and is conducive to ensuring the construction quality of concrete paving and leveling. Multiple vibrating assemblies 4 further expand the vibration range and improve the vibration efficiency.

[0029] See Figure 5 Furthermore, in the present embodiment, the vibrating assembly 4 includes a mounting seat 41 and a vibrating rod 42 disposed on the mounting seat 41. The mounting seat 41 is hinged to the crossbeam 8 via a first hinge portion 411. The mounting seat 41 is hinged to the swing drive mechanism 5 via a second hinge portion 412. The swing drive mechanism 5 drives the mounting seat 41 to rotate around the first hinge portion 411 and thereby drives the vibrating rod 42 to swing. The structure is simple and effective.

[0030] See Figure 4 and Figure 5 Furthermore, in this embodiment, the swing drive mechanism 5 includes a telescopic drive member 51 and a connecting rod 52 for making at least two vibrating rods 42 swing synchronously. One end of the telescopic drive member 51 is hinged to the cross beam 8, and the other end is hinged to one of the second hinged parts 412. The connecting rod 52 is hinged to at least two second hinged parts 412. The telescopic drive member 51 drives the vibrating assembly 4 to reciprocate around the hinge between it and the cross beam 8 through telescopic movement, thereby realizing the swing of the vibrating rod 42. When the telescopic drive member 51 is extended to a certain length, the vibrating rod 42 can be separated from the concrete and remain parallel to the cross beam 8 (see for details). Figure 4 ), which is helpful to reduce the occupied space and make transportation more convenient. When the telescopic driving member 51 is extended to a specific length, the vibrating rod 42 can be made perpendicular to the crossbeam 8 (see Figure 5 ), at this time, the vibration rod 42 can reach the maximum vibration depth. Specifically, in this embodiment, two telescopic driving members 51 are provided and located in the middle of the crossbeam 8. The two telescopic driving members 51 are respectively hinged to the vibration assemblies 4 on both sides of the crossbeam 8. The telescopic driving members 51 can be components such as oil cylinders, air cylinders or electric push rods. Of course, in other embodiments, the telescopic driving member 51 can be provided on one side of the crossbeam 8. Only one telescopic driving member 51 and the connecting rod 52 connecting each group of vibration assemblies 4 can also drive the vibration assembly 4 to swing. The actual number and arrangement position of the telescopic driving members 51 can be flexibly set according to actual conditions, and the details will not be repeated.

[0031] See Figure 1and Figure 3 Furthermore, in this embodiment, the first lifting mechanism 6 includes two first lifting driving members 61 and is disposed on two traveling frames 2, and the two ends of the beam 8 are correspondingly connected to the two first lifting driving members 61. The first lifting driving members 61 at both ends of the beam 8 simultaneously drive the beam 8 to lift and lower, with good symmetry and balance, which can ensure that the beam 8 remains horizontal, and is conducive to ensuring the consistency of the vibration depth of each group of vibration components 4.

[0032] See Figure 4 and Figure 5 Furthermore, in the present embodiment, a first lifting guide structure 62 (such as a guide column and a guide sleeve, a guide rail and a slide rail, a guide rail and a pulley, etc.) is provided between the beam 8 and the traveling frame 2, which can improve the stability and accuracy of the beam 8 during the lifting process.

[0033] See Figures 1 to 3 Furthermore, in the present embodiment, the second lifting mechanism 7 includes two second lifting driving members 71 which are separately arranged on the two running frames 2; the paving and leveling mechanism 3 includes a leveling component 31; both ends of the leveling component 31 are correspondingly connected to the two second lifting driving members 71; the two second lifting driving members 71 simultaneously drive the paving and leveling mechanism 3 to rise and fall, and have good symmetry and balance, thereby ensuring that the paving and leveling mechanism 3 remains horizontal and ensures the leveling quality of the paving and leveling mechanism 3.

[0034] See Figure 2 Furthermore, in this embodiment, the paving and leveling mechanism 3 also includes a vibrator 32, and the vibrator 32 is connected to the leveling component 31. The vibrator 32 applies vibration to the leveling component 31, which is transmitted to the concrete surface through the leveling component 31, so that the concrete surface is flat, which is conducive to improving the quality of paving and leveling.

[0035] See Figure 2 Furthermore, in this embodiment, a second lifting guide structure 72 (such as a guide column and a guide sleeve, a guide rail and a slide rail, a guide rail and a pulley, etc.) is provided between the leveling component 31 and the traveling frame 2, which can improve the stability and accuracy of the paving and leveling mechanism 3 during the lifting process.

[0036] The construction method of the concrete paving and leveling device implemented in this embodiment is as follows:

[0037] The running frame 2 first moves on the trestle 1 to the starting end of the area where paving and leveling are required (when performing concrete paving and leveling construction, the vibrating rod 42 is located in front of the leveling component 31 in the forward direction of the running frame 2). Then, according to the required vibration depth, the first lifting mechanism 6 drives the crossbeam 8 to descend, thereby driving the vibrating rod 42 to descend and insert into the concrete, and the telescopic drive member 51 can swing the vibrating rod 42 by telescoping to adjust the direction of the vibrating rod 42. According to the height of the concrete surface, the second lifting mechanism 7 drives the leveling component 31 to descend and fit closely to the concrete surface, and starts the vibrator 32. Then, the running frame 2 moves forward in the paving and leveling construction direction, and the first lifting mechanism 6 and the second lifting mechanism 7 are lifted and lowered according to actual needs. The running frame 2 moves to the terminal end of the area where paving and leveling are required, completing the concrete paving and leveling operation of a construction section. Repeat the above steps to complete the concrete paving and leveling operation of all construction sections. The concrete paving and leveling device of this embodiment can be moved and transported together with the trestle 1 . During the movement and transportation, the telescopic driving member 51 drives the vibrating rod 42 to rotate to be parallel to the crossbeam 8 .
