Description

Technical Field

[0001] The present invention relates to the technical field of engineering machinery, in particular to a multifunctional concrete forming machine. Background Art

[0002] Currently, large-scale concrete construction is still primarily labor-intensive, supplemented by small-scale equipment for concrete paving, slurry treatment, and finishing. This construction method suffers from unstable construction quality, slow construction progress, and high construction costs. To address these issues, Chinese patent CN102561263A discloses a light collecting machine. A motor-driven chain drive is mounted on the main frame of the light collecting machine. Light collecting devices are installed at regular intervals on the chain of the chain drive. The light collecting device is equipped with a floating and variable light collecting plate for shaping the surface of the light-collecting concrete. However, the light collecting device is driven by a chain. When the light collecting plate encounters an uneven concrete surface, the chain bends, resulting in insufficient positive pressure on the trowel plate, an unsatisfactory troweling effect, and the trowel plate cannot achieve a slurry treatment effect. Furthermore, the truss structure of the machine is not suitable for applications with variable slope ratios or variable slope lengths.

[0003] The current concrete surface finishing machine represented by patent CN102561263A has improved construction efficiency and saved construction costs to a certain extent compared with manual operation methods, but it still has limitations and poor construction effects. Summary of the Invention

[0004] The present invention aims to provide a multifunctional concrete forming machine to solve the technical problem that conventional concrete forming machines cannot perform concrete surface finishing and forming operations in scenarios with large flat surfaces, variable slope ratios, variable slope lengths, and flat and inclined surfaces. The specific technical solution is as follows: The present invention provides a multifunctional concrete forming machine, comprising: an upper walking system, the upper walking system comprising a first liftable movable vehicle and a turntable, the turntable being rotatably mounted on the first liftable movable vehicle; a lower walking system, the lower walking system comprising a second liftable movable vehicle; a telescopic truss, a first end of the telescopic truss being hinged to the turntable, and a second end of the telescopic truss being hinged to the second liftable movable vehicle; a vibration forming assembly, the vibration forming assembly being slidably mounted on the telescopic truss; the vibration forming assembly comprising two first vibration forming rollers, the two first vibration forming rollers being slidably mounted on the outer truss and the inner truss respectively; the first vibration forming roller comprising an eccentric shaft, a roller body and a plurality of trowel blades, the roller body being mounted on the eccentric shaft, and the plurality of trowel blades being mounted on the surface of the roller body in the same rotation direction.

[0005] A further improvement of the multifunctional concrete forming machine of the present invention is that the first liftable movable vehicle includes a wheel set, a lifting drive member and a vehicle frame, the lifting drive member is connected between the vehicle frame and the wheel set, and the turntable is rotatably mounted on the vehicle frame.

[0006] A further improvement of the multifunctional concrete forming machine of the present invention is that the frame body includes a U-shaped base frame, the turntable is rotatably mounted on the middle of the base frame, and the turntable is provided with two hinged columns for hinged connection of two sides of the telescopic truss.

[0007] A further improvement of the multifunctional concrete forming machine of the present invention is that a generator set for power supply is provided on the frame body.

[0008] A further improvement of the multifunctional concrete forming machine of the present invention is that the lifting drive member is a hydraulic oil cylinder, and the frame body is provided with a hydraulic pump station connected to the hydraulic oil cylinder.

[0009] A further improvement of the multifunctional concrete forming machine of the present invention is that the telescopic truss includes an outer truss and an inner truss, the outer truss is slidably mounted on the outer periphery of the inner truss, a slide rail is provided on the outer side of the inner truss, and a sliding wheel group that cooperates with the slide rail is provided inside the outer truss.

[0012] The application of the technical solution of the present invention has the following beneficial effects: The multifunctional concrete forming machine of the present invention utilizes a vibrating forming assembly mounted on a telescopic truss to achieve finishing and plastering operations on various slopes. A turntable can be used to horizontally rotate around the center of the upper travel system chassis to resolve the issue of asynchrony between the upper and lower travel systems during large-angle turns. The telescopic truss is hinged to the turntable, enabling vertical swing of the truss, addressing the common problem of the machine operating at different slope ratios. The telescopic trusses can slide relative to each other, adaptively changing the truss length when the slope length varies. Furthermore, the equipment can also adaptively change the length and angle of the telescopic truss when the slope length, slope ratio, or large-angle turns vary. Two sets of vibrating forming rollers are used to achieve finishing and plastering operations.

The drive motor 111 can ensure accurate positioning of the vehicle and move along a pre-set track to ensure the accuracy of the smoothing and finishing construction.

[0020] Preferably, the frame body 14 includes a U-shaped base frame 15, and the turntable 16 is rotatably installed in the middle of the base frame 15. The turntable 16 is provided with two hinged columns for hinged connection of the telescopic truss 3 on both sides. The telescopic truss 3 is located between the two hinged columns. The midpoint of the turntable 16 is connected to the base frame 15 by a pin shaft, so that the turntable 16 can realize horizontal rotation. The first liftable mobile vehicle and the second liftable mobile vehicle have the same structure. The second liftable mobile vehicle is provided with an hinged frame for hinged connection of the telescopic truss 3 only on the side of the base frame 15 close to the first liftable mobile vehicle, so as to realize the application of variable slope ratio and large turning scenarios, and under the drive of the lifting drive 13, the telescopic truss 3 can swing up and down in the vertical direction.

[0021] Preferably, the frame body 14 is provided with a generator set 181 for powering the machine. When operating without power, the generator set 181 serves as a backup power source, automatically switching to the backup power source in the event of a power outage to ensure normal operation. Alternatively, the machine can be operated independently of the mains electricity supply and powered solely by the generator set. The frame body 14 is provided with a top platform 18, to which the generator set 181 is fixed. An electrical control cabinet 182 is also provided on the top platform 18 of the frame body 14. The generator set 181 is connected to the electrical control cabinet 182, and all electrical equipment on the first elevating movable vehicle, the telescopic truss 3, the second elevating movable vehicle, and the vibration molding assembly is connected to the electrical control cabinet 182. The second elevating movable vehicle is also provided with a top platform 18, on which an operating console 19 and an electrical control cabinet 182 are provided. The operating console 19 is connected to the electrical control cabinet 182, and the operating console 19 is connected to all operating equipment of the multifunctional concrete forming machine, enabling remote control of all operations of the machine. In this embodiment, the generator set 181 can be composed of a diesel generator.

[0022] Preferably, the lifting drive 13 is a hydraulic cylinder, and the frame body 14 is provided with a hydraulic pump station 17 connected to the hydraulic cylinder. The wheel set is hinged to the hydraulic cylinder piston rod, and the cylinder body is hinged to the frame body 14 column. The telescopic column of the wheel set is placed in the four square holes of the base frame 15. Wear-resistant strips are provided on the periphery of the telescopic column, which can be extended and retracted along the square holes. The hydraulic pump station 17 of the second liftable mobile vehicle is set in the middle position of the base frame 15. When the molding machine crosses an obstacle, the entire walking system can be raised by the hydraulic cylinder. The upper and lower walking system 2 support cylinders cooperate with each other to drive the middle telescopic truss 3 to rise and fall, and control the height of the first vibration molding roller 4 according to construction requirements.

[0023] Preferably, Figure 6 and Figure 7 As shown, the telescopic truss 3 includes an outer truss 31 and an inner truss 32. The outer truss 31 is slidably mounted on the outer periphery of the inner truss 32. A slide rail 35 is provided on the outer side of the inner truss 32, and a sliding wheel set that cooperates with the slide rail 35 is provided inside the outer truss 31. The inner and outer trusses can slide relative to each other along the slide rail, and the length of the telescopic truss 3 can be adaptively changed in scenarios where the slope length varies. A limit device 34 is provided at the end of the slide rail. The limit device 34 is fixed to the end position of the slide rail 35 and is used to prevent the sliding wheel set from sliding out of the slide rail 35. A proximity switch 36 is provided on the slide rail 35 at a position corresponding to the limit device 34. The proximity switch 36 is used to generate a signal with the drive motor of the sliding wheel set. When the sliding wheel set approaches the limit device 34, the drive motor is controlled to stop running.

[0024] Preferably, the vibration forming assembly includes two first vibration forming rollers 4, which are respectively slidably mounted on the outer truss 31 and the inner truss 32. The device for slidingly mounting the first vibration forming rollers 4 can adopt a conventional sliding structure in the prior art, such as a structure in which a track and a motorized pulley cooperate.

[0025] Preferably, the first vibrating forming roller 4 includes an eccentric shaft 43, a roller body 42, and a plurality of trowel blades 41. The roller body 42 is mounted on the eccentric shaft 43, and the plurality of trowel blades 41 are mounted on the surface of the roller body 42 in the same rotation direction. Specifically, the same rotation direction refers to clockwise or counterclockwise. There is partial overlap between two adjacent trowel blades 41. The high-speed rotation of the roller body 42 simulates the effect of manual smoothing, ensuring that the concrete surface is smoothed and leveled. At the same time, the interior of the forming roller is designed with an eccentric shaft 43 to provide high-frequency vibration. Specifically, the internal hydraulic drive motor drives the eccentric shaft 43 to rotate at high speed. The high-speed rotation of the eccentric shaft 43 provides an exciting force, causing the roller body to vibrate at high frequency and transmit it to the trowel blades distributed on the surface of the roller body 42. The trowel blades 41 vibrate at high frequency and beat the concrete surface to achieve a slurry-raising effect. The first vibrating forming roller 4 moves up and down along the slope, and the trowel blades 41 smooth the concrete surface while vibrating at high frequency, thereby achieving a lightening and slurry-raising effect during smoothing.

[0026] Preferably, Figure 7 As shown, both the inner truss 32 and the outer truss 31 are equipped with roller frames 33, with second vibration forming rollers 6 located below the roller frames 33. Specifically, the second vibration forming rollers 6 are bolted to the roller frames 33 via flange plates on both sides. The roller frames 33 are positioned near the ends of the inner and outer trusses 31, respectively. While not affecting the telescopic truss 3's extension and retraction, the roller frames 33 allow the telescopic truss 3 to slide forward and backward along the slope's length. This sliding motion drives the second vibration forming rollers 6 to smooth and finish the surface. When the telescopic truss 3 is fully extended, a cross section exists between the inner and outer trusses 31, ensuring that the operating positions of the vibration forming rollers of the inner and outer trusses 32 and 31 overlap.

[0027] Preferably, the multifunctional concrete forming machine further includes two cleaning systems 5, each fixed to the first and second elevating movable vehicles. The cleaning systems 5 include a water tank 51 and a water pump 52 for connecting an external water source to the water tank 51. The cleaning systems 5 can also be equipped with cleaning tools, such as spray guns, as needed to facilitate cleaning operations on the first and second vibrating forming rollers 4, 6, and other equipment.

[0028] The operation steps of the multifunctional concrete forming machine are as follows: 1. Lay tracks on both sides of the construction site, hoist the upper and lower travel systems 2 to one side of the site, place the active track wheel set 11 on the track, and then hoist the telescopic truss 3 to complete the assembly of the multifunctional concrete forming machine.

[0029] 2. Install two sets of first vibration forming rollers 4 onto the roller frame 33.

[0030] 3. The whole machine stops at the position where the lining surface needs to be smoothed, and the first vibration forming roller 4 is operated to smooth and smooth the surface. After completion, the whole machine moves forward and continues to work at the next position. This uninterrupted cycle completes the smoothing and smoothing of the entire lining surface.

[0031] The multifunctional concrete forming machine of the present invention utilizes a vibrating forming assembly mounted on a telescopic truss 3 to achieve finishing and plastering operations on various slopes. A turntable 16 allows horizontal rotation around the center of the upper travel system 1 chassis 15, resolving the issue of asynchrony between the upper and lower travel systems 2 during steep turns. The telescopic truss 3 is hinged to the turntable 16, enabling vertical swinging of the truss 3, addressing the machine's commonality with varying slope ratios. The telescopic trusses 3 can slide relative to each other, adaptively changing their length as the slope length changes. Furthermore, the length and angle of the telescopic trusses 3 can be adjusted adaptively during steep turns with varying slope lengths and ratios. Two sets of vibrating forming rollers are used to achieve finishing and plastering. This eliminates the need for manual intervention, reduces labor intensity, accelerates construction progress, and saves construction costs.
