Description

Technical Field

[0001] This invention belongs to the field of building engineering technology, and specifically relates to a mobile concrete continuous vibration device. Background Technology

[0002] In concrete construction, vibration is a crucial step in ensuring the density, strength, and durability of concrete. Traditional concrete vibration often employs handheld vibrators, which are inserted by operators into the freshly poured concrete for localized vibration. This method is labor-intensive, inefficient, and the vibration quality is highly dependent on the operator's experience, easily leading to problems such as under-vibration, over-vibration, or uneven vibration. This is especially problematic in large-area or continuous pouring scenarios, where maintaining continuity and consistency in vibration is difficult. To improve automation, some mobile or track-mounted vibration equipment has emerged on the market, attempting to replace manual operation with mechanical structures.

[0003] However, existing automatic vibration compaction devices still have significant technical shortcomings. Most devices use fixed vibrating heads or single vibrating units, which can only perform limited vibration in localized areas, failing to achieve a continuous forward-moving operation mode, resulting in frequent construction interruptions and limited efficiency. Although some devices introduce multiple vibrating heads to expand the coverage area, all vibrating heads often work synchronously, and prolonged continuous operation can easily lead to overheating of the vibrating motor, affecting the reliability and service life of the equipment. In addition, existing devices usually use a constant speed when inserting and withdrawing the vibrating rod from the concrete, failing to optimize for the rheological properties of concrete: rapid insertion can reduce disturbance to the concrete structure, while slow withdrawal helps avoid the formation of voids or cracks, but existing technologies generally lack differentiated control over this process.

[0004] Another technical bottleneck lies in the coordination between walking and vibration actions. Some equipment fixes the vibration mechanism directly to the walking chassis, which requires the whole machine to be frequently started and stopped during the vibration process to match the vibration rhythm. This not only reduces construction efficiency, but may also interfere with the vibration effect due to walking vibration.

[0005] In summary, current concrete vibration technology still has significant shortcomings in terms of continuous operation capability, vibration process control, and walking-vibration coordination. There is an urgent need for a new type of mechanical device that can achieve efficient, continuous, reliable, and adaptive vibration operation. Summary of the Invention

[0006] The purpose of this invention is to solve the above-mentioned technical problems, and thus proposes a walking-type continuous concrete vibration machine, which has the advantages of improving vibration efficiency, realizing continuous operation, optimizing insertion and extraction speed control, thereby improving the quality and reliability of concrete construction.

[0007] This application provides a mobile continuous concrete vibrating machine, the technical solution of which is as follows: a walking mechanism for driving the whole machine to walk along the ground; A circular track mechanism, fixed to a traveling mechanism, is provided with a closed circular guide rail, which includes a bottom straight guide rail, a top straight guide rail, a front semicircular guide rail, and a rear semicircular guide rail. Multiple sliders circulate along a circular guide rail; Synchronous belt and synchronous belt drive assembly, used to drive the slider to move cyclically along the annular guide rail; The vibration position drive mechanism is rotatably connected to the slider and includes a first cantilever, a second cantilever, a lateral drive device and a vertical drive device. The second cantilever is sleeved outside the first cantilever, and the lateral drive device connects the first cantilever and the second cantilever and adjusts the lateral position of the second cantilever. The vibration mechanism includes a vibration motor, a hose, and a vibration rod head. The vibration motor is fixed to the lower part of the first cantilever, and the vertical drive device is fixed to the bottom of the second cantilever. Its output end is connected to the vibration rod head, driving the vibration rod head to move in the vertical direction. The linear speed of the synchronous belt is the same as the traveling speed of the traveling mechanism; When the vertical drive device moves to the area where the front semicircular guide rail and the bottom straight guide rail are connected, it drives the vibrator head to quickly insert it downward into the concrete. The vibrator head remains in the same relative position to the concrete in the bottom straight guide rail section and continues to vibrate; When the vertical drive device moves to the area where the vibrating rod head connects to the bottom straight guide rail, it drives the vibrating rod head to slowly pull the concrete upward. The vibrating rod head stops vibrating at the top straight guide rail section and returns to the insertion position with the slider, realizing continuous vibration and alternating operation.

[0008] Furthermore, this application also proposes that the walking mechanism includes a frame, a track, a first drive wheel, a first driven wheel, and a drive motor. The first drive wheel and the first driven wheel are rotatably mounted at the front and rear ends of the frame, respectively. The track is wrapped around the outside of the first drive wheel and the first driven wheel. The drive motor is fixed to the frame and is connected to the first drive wheel for transmission.

[0009] Furthermore, this application also proposes that there are two first drive wheels, symmetrically arranged along the centerline of the width direction of the frame; two tracks are provided, respectively wrapped around the outside of the corresponding first drive wheel and the first driven wheel; the annular track mechanism is correspondingly configured as two sets, respectively fixed on the left and right sides of the frame, and respectively connected to the corresponding first drive wheel for transmission.

[0010] Furthermore, this application also proposes that the annular track mechanism includes a housing and an annular guide rail, the housing being fixed to the frame and the annular guide rail being fixed to the outer wall of the housing; the bottom straight guide rail and the top straight guide rail are arranged horizontally, the front semicircular guide rail connects the front end of the bottom straight guide rail and the front end of the top straight guide rail, and the rear semicircular guide rail connects the rear end of the bottom straight guide rail and the rear end of the top straight guide rail.

[0011] Furthermore, this application also proposes that the slider includes a roller and a connecting seat; the roller is installed at the bottom of the slider and rolls in contact with both sides of the annular guide rail; one end of the connecting seat is fixed to the slider, and the other end is hinged to the timing belt through a pin.

[0012] Furthermore, this application also proposes that the synchronous belt drive assembly includes a second drive wheel, a second driven wheel, a synchronous belt drive shaft, and a bushing. The second drive wheel is connected to the first drive wheel via a chain drive mechanism. The second drive wheel and the second driven wheel are rotatably mounted at the front and rear ends of the housing, respectively. The synchronous belt is wound around the outside of the second drive wheel and the second driven wheel. The synchronous belt drive shaft is coaxially and fixedly connected to the second drive wheel. The bushing is sleeved on the synchronous belt drive shaft and fixed to the housing.

[0013] Furthermore, this application also proposes that the slider further includes a support shaft, which is vertically fixed to the front end face of the slider; one end of the first cantilever is rotatably connected to the support shaft via a bearing; the cylinder of the lateral drive device is hinged to the side wall of the first cantilever, and the piston rod is hinged to the side wall of the second cantilever; the cylinder of the vertical drive device is fixed to the bottom of the second cantilever, and the output end is connected to the vibrating rod head; a guide key and a keyway are provided between the first cantilever and the second cantilever, the guide key is fixed to the outer wall of the first cantilever, and the keyway is provided to the inner wall of the second cantilever, the two working together to restrict the relative rotation of the first cantilever and the second cantilever.

[0014] Furthermore, this application also proposes that the hose is a flexible drive shaft, with one end connected to the output shaft of the vibrating motor and the other end connected to the vibrating rod head; the vibrating rod head is fixedly connected to the output end of the vertical drive device.

[0015] Furthermore, this application also proposes that the device further includes a seamless annular sliding contact line, a current collector, and an intermediate power supply; the seamless annular sliding contact line is fixed to the outer wall of the housing and arranged around the annular guide rail; the current collector is fixed to the slider and electrically connected to the seamless annular sliding contact line; the intermediate power supply is electrically connected to both the seamless annular sliding contact line and an external power source.

[0016] Furthermore, this application also proposes that multiple vibrating rod heads are evenly distributed in the horizontal direction on the bottom straight guide rail section; the front semicircular guide rail and the rear semicircular guide rail have the same radius of curvature, and are connected to the bottom straight guide rail and the top straight guide rail by a smooth arc transition.

[0017] Compared with existing technologies, the beneficial effects achieved by this invention are as follows: By setting up a cooperative structure of a walking mechanism and a circular track mechanism, this invention enables the entire machine to move stably along the ground tracks on both sides of the concrete, achieving effective immersion vibration and coordinated forward movement of the device, thus enabling continuous operation. The circular track mechanism has a closed circular guide rail on which multiple sliders circulate and are driven by a synchronous belt. The linear speed of the synchronous belt is consistent with the walking speed of the walking mechanism, thereby ensuring that the vibrator head is stationary relative to the concrete surface in the bottom straight guide rail section, achieving efficient and dense vibration. The vibration position drive mechanism adopts a double cantilever structure, combined with a lateral drive device and a vertical drive device, which can adjust the lateral working range and vertical insertion and withdrawal action of the vibrator head respectively. Especially in the area where the front semicircular guide rail connects to the bottom straight guide rail, the vibrator head is quickly inserted to reduce secondary disturbance or vibration to the upper layer of concrete, thereby avoiding over-vibration of the upper layer of concrete. In the area where the rear semicircular guide rail connects to the bottom straight guide rail, it is slowly withdrawn to prevent voids and allow sufficient time for air bubbles to escape, significantly improving the vibration quality. Multiple vibration mechanisms work in turn, avoiding overheating caused by prolonged operation of a single vibration unit, thus improving the equipment's continuous operation capability and reliability. Furthermore, the use of a seamless annular sliding contact line with a current collector for power supply completely solves the problem of cable entanglement in cyclic moving parts, ensuring the stability of the entire machine's operation and ease of maintenance. The overall structure achieves automated, continuous, and adaptive control of the vibration process. Attached Figure Description

[0021] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0022] Please see the appendix Figure 1-6 In response, this embodiment provides a mobile concrete continuous vibration device, which includes: A traveling mechanism 100 is used to drive the entire machine to travel along the ground above both sides of the concrete surface; a circular track mechanism 200 is fixed to the traveling mechanism 100 and is provided with a closed circular guide rail 220, which includes a bottom straight guide rail 221, a top straight guide rail 222, a front semicircular guide rail 223, and a rear semicircular guide rail 224; multiple sliders 230 circulate along the circular guide rail 220; a synchronous belt 240 and a synchronous belt drive assembly are used to drive the sliders 230 along the circular guide rail. 220 cyclic motion; Vibration position drive mechanism 300, rotatably connected to slider 230, includes a first cantilever 310, a second cantilever 320, a lateral drive device 330, and a vertical drive device 340. The second cantilever 320 is sleeved outside the first cantilever 310. The lateral drive device 330 connects the first cantilever 310 and the second cantilever 320 and adjusts the lateral position of the second cantilever 320; Vibration mechanism 400 includes a vibration motor 410, a hose 420, and a vibrating rod. The head 430, the vibrating motor 410 is fixed to the lower part of the first cantilever 310, the vertical drive device 340 is fixed to the bottom of the second cantilever 320, and its output end is connected to the vibrating head 430, driving the vibrating head 430 to move vertically; the linear velocity of the synchronous belt 240 is the same as the travel speed of the traveling mechanism 100; the vertical drive device 340 drives the vibrating head 430 when it runs to the area where the front semi-circular guide rail 223 and the bottom straight guide rail 221 are connected. 430 is quickly inserted downward into the concrete; the vibrator head 430 maintains a constant relative position with the concrete in the bottom straight guide rail 221 section and continues to vibrate; when the vibrator head 430 runs to the area where the rear semicircular guide rail 224 connects with the bottom straight guide rail 221, the vertical drive device 340 drives the vibrator head 430 to slowly pull the concrete upward; the vibrator head 430 stops vibrating in the top straight guide rail 222 section and returns to the insertion position with the slider 230, realizing continuous vibration and alternating work.

[0023] This embodiment of the mobile continuous concrete vibratory compaction device effectively solves the problems of high labor intensity, low efficiency, and uneven compaction quality associated with traditional vibration methods by utilizing the coordinated action of the walking mechanism 100 and the circular track mechanism 200, as well as the synchronous belt 240 driving multiple vibration mechanisms 400 in cyclic operation. The device achieves continuous vibration of the vibratory head 430 while maintaining a constant relative position to the concrete on the bottom straight guide rail 221. Furthermore, it can optimize the vibration process by allowing for rapid insertion and slow withdrawal of the vibratory head 430 in specific areas based on the rheological properties of the concrete. In addition, the alternating operation mode of multiple vibratory heads 430 avoids overheating issues caused by prolonged operation of a single vibratory head, significantly improving the continuity, consistency, and reliability of concrete vibration operations.

[0024] like Figure 1 , Figure 2As shown, in trackless vibratory compaction applications, the traveling mechanism 100 can adopt a tracked structure. This application further proposes the specific composition of the traveling mechanism 100, which includes a frame 130, tracks 110, a first drive wheel 120, a first driven wheel 150, and a drive motor 140. The frame 130 is the main structure of the traveling mechanism 100, and its main function is to provide robust support and a mounting platform for the entire traveling mechanism. The frame 130 is welded from high-strength steel, possessing sufficient rigidity and strength to withstand the loads and vibrations during operation. The tracks 110 are key components that allow the traveling mechanism 100 to contact the concrete ground on both sides and generate traction. The tracks 110 are made of rubber material and have a large ground contact area. Simultaneously, the surface texture design of the tracks 110 provides excellent grip, ensuring sufficient traction even on wet or soft ground and preventing slippage. The first drive wheel 120 is the power output component that drives the tracks 110. It is typically a toothed wheel or friction wheel, which closely engages with the teeth or surface of the inner side of the track 110, driving the track 110 to circulate through rotation. The first driven wheel 150 is arranged opposite to the first drive wheel 120, and its main function is to support the track 110 and guide its circulation path. The structure of the first driven wheel 150 is the same as that of the first drive wheel 120. Its installation position and tensioning device can adjust the tension of the track 110 to ensure that the track 110 maintains appropriate tension during operation, avoiding derailment or excessive wear. The drive motor 140 is the core component that provides power to the traveling mechanism 100. The drive motor 140 can be an AC motor or a DC motor, which transmits power to the first drive wheel 120 through a transmission device such as a reducer, thereby driving the track 110 to move. The power and speed of the drive motor 140 should be matched with the overall traveling speed and required traction force of the machine, and have precise speed control capabilities. Specifically, the first drive wheel 120 and the first driven wheel 150 are rotatably mounted at the front and rear ends of the frame 130 via bearings or other means, ensuring that they can rotate freely and bear loads. The track 110 is wound around the outside of the first drive wheel 120 and the first driven wheel 150, forming a closed transmission circuit. The drive motor 140 is fixed to the frame 130 and is connected to the first drive wheel 120 for transmission, effectively transmitting power to the track 110.

[0025] This application further proposes that there be two first drive wheels 120, which are symmetrically arranged along the centerline of the width direction of the frame 130; two tracks 110 are provided, which are respectively wrapped around the outside of the corresponding first drive wheel 120 and the first driven wheel 150; and two sets of annular track mechanisms 200 are respectively fixed on the left and right sides of the frame 130 and respectively connected to the corresponding first drive wheels 120 for transmission.

[0026] Considering that the typical application scenario of the device of the present invention in actual engineering is the concrete vibration operation of large longitudinal structures or components, such structures or components usually have a certain height and internal steel reinforcement, making it impossible for tracks to travel on them. Therefore, in such applications, the walking mechanism 100 can be adapted to a track-type walking structure: parallel guide rails are pre-laid on both sides of the width direction of the large longitudinal structure or component (or automatically laid by the front end of the device), and the walking mechanism 100 eliminates the tracks 110, the first drive wheel 120, and the first driven wheel 150, replacing them with a set of walking rollers that roll along the tracks on both sides. The roller set is mounted on both sides of the bottom of the frame 130 through bearings, and its axles are arranged along the longitudinal direction of the structure or component to ensure that the whole machine moves stably along the track. The drive motor 140 is still retained and is connected to any of the walking rollers through a reduction transmission mechanism to achieve uniform speed walking.

[0027] When a single circular track mechanism 200 is used for vibration operation, its vibration width is limited, and it may not be able to cover a wide concrete pouring surface in one go. This requires multiple trips or adjustments to the equipment position, reducing construction efficiency. By setting a set of circular track mechanisms 200 on each of the left and right sides of the frame 130, synchronous vibration of dual areas or a wider amplitude can be achieved.

[0028] like Figure 1 , Figure 4 As shown, this application further proposes a ring track mechanism 200 including a housing 210 and a ring guide rail 220. The housing 210 is fixed to the frame 130, and the ring guide rail 220 is fixed to the outer wall of the housing 210. The bottom straight guide rail 221 and the top straight guide rail 222 are arranged horizontally. The front semicircular guide rail 223 connects the front end of the bottom straight guide rail 221 and the front end of the top straight guide rail 222, and the rear semicircular guide rail 224 connects the rear end of the bottom straight guide rail 221 and the rear end of the top straight guide rail 222.

[0029] Specifically, the housing 210 typically refers to a shell with a closed or semi-closed structure, which provides support and installation space for the annular track mechanism 200. The housing 210 can be welded or integrally formed from steel plates, aluminum alloys, or other high-strength materials to ensure sufficient rigidity and strength. The frame 130 is the main structure of the entire mobile continuous concrete vibrating machine, bearing all major components. The housing 210 is securely fixed to the frame 130, for example, by bolting, welding, or riveting. The annular guide rail 220 is the path for the slider 230 to run along; it is fixed to the outer wall of the housing 210. The annular guide rail 220 can be made of high-wear-resistant steel or other composite materials and is tightly connected to the outer wall of the housing 210 by welding, bolting, or slotting. The bottom straight guide rail 221 is the main area where the vibrator head 430 performs vibration work in the concrete, while the top straight guide rail 222 is the area where the vibrator head 430 returns in the air. Arranging these two straight guide rails horizontally ensures that the vibrator head 430 maintains a stable vibration depth on the bottom straight guide rail 221 after insertion into the concrete, avoiding inconsistent vibration depth due to guide rail tilt. Simultaneously, the horizontal arrangement on the top straight guide rail 222 facilitates a smooth return stroke for the vibrator head 430, preparing it for the next insertion. The front semi-circular guide rail 223 serves as a transition section, connecting the bottom straight guide rail 221 and the top straight guide rail 222. Its function is to guide the slider 230 and its connected vibrator head 430 smoothly from the top straight guide rail 222 to the bottom straight guide rail 221, completing the rapid downward insertion of the vibrator head 430 in this area. The arc connection provides a smooth movement trajectory, reducing impact and wear. Similar to the front semi-circular guide rail 223, the rear semi-circular guide rail 224 also serves as a transition section, connecting the bottom straight guide rail 221 and the top straight guide rail 222. Its function is to guide the slider 230 and its connected vibratory rod head 430 to smoothly transition from the bottom straight guide rail 221 to the top straight guide rail 222, and to complete the slow upward pulling action of the vibratory rod head 430 in this area. The arc connection also ensures the smoothness and continuity of the movement.

[0030] like Figure 4 , Figure 5 As shown, this application further proposes a structure for a slider 230, which includes a roller 232 and a connecting seat 233. The roller 232 is mounted on the bottom of the slider 230 and rolls in contact with both sides of the annular guide rail 220; one end of the connecting seat 233 is fixed to the slider 230, and the other end is hinged to the synchronous belt 240 via a pin.

[0031] Specifically, the slider 230 is a key component that supports the vibratory mechanism 400 and moves along the annular guide rail 220. Its internal structural design is crucial for achieving smooth and reliable movement. The roller 232 enables the slider 230 to move on the annular guide rail 220 through rolling friction. The roller 232 can take various forms, such as a roller with a V-groove that cooperates with a V-shaped guide rail to ensure the positioning accuracy and operational stability of the slider 230 on the guide rail. Through rolling contact with both sides of the annular guide rail 220, the roller 232 can effectively support the weight of the slider 230 and guide it to move smoothly along a predetermined path, avoiding jamming or deviation. The connecting seat 233 is a key structure for transmitting driving force from the synchronous belt 240 to the slider 230. One end is firmly fixed to the slider 230, ensuring that the driving force can be reliably transmitted to the slider 230 body. The other end is hinged to the synchronous belt 240 via a pin. This hinged connection allows for a certain degree of relative rotational freedom between the synchronous belt 240 and the slider 230. This flexible connection can effectively compensate for the slight angular deviation or vibration that may occur in the synchronous belt 240 during movement, and avoid stress concentration or jamming caused by rigid connection, thereby ensuring the smoothness and reliability of power transmission.

[0032] like Figure 4 , Figure 5 As shown, this application further proposes a specific structure for a synchronous belt drive assembly, which includes a second drive wheel 250, a second driven wheel 260, a synchronous belt drive shaft 251, and a bushing 252. The second drive wheel 250 and the second driven wheel 260 are rotatably mounted at the front and rear ends of the housing 210, respectively, and the synchronous belt 240 is wound around the outside of the second drive wheel 250 and the second driven wheel 260. The synchronous belt drive shaft 251 is coaxially and fixedly connected to the second drive wheel 250, while the bushing 252 is sleeved on the synchronous belt drive shaft 251 and fixed to the housing 210.

[0033] Specifically, the second drive wheel 250 is the power input end of the synchronous belt 240. The second drive wheel 250 is connected to the first drive wheel 120 via a chain drive mechanism 160. Through engagement with the synchronous belt 240, it transmits the driving force from the first drive wheel 120 to the synchronous belt 240, causing it to circulate along the annular guide rail 220. The chain drive mechanism 160 consists of sprockets and chains of the same diameter. Since the second drive wheel 250 has the same diameter as the first drive wheel 120, the linear velocity of the track 110 is the same as that of the synchronous belt 240. The second driven wheel 260 serves as a guide and tensioning component for the synchronous belt 240. Together with the second drive wheel 250, it supports and guides the running trajectory of the synchronous belt 240, ensuring that the synchronous belt 240 maintains appropriate tension during operation and preventing slack or skipped teeth. The second drive wheel 250 and the second driven wheel 260 are both designed to be rotatably mounted at the front and rear ends of the housing 210. This layout helps to form a closed and stable transmission circuit and makes full use of the structural space of the housing 210 to achieve a compact design. The synchronous belt drive shaft 251 is a key component connecting the chain drive mechanism 160 and the second drive wheel 250. It is coaxially fixedly connected to the second drive wheel 250, ensuring the directness and efficiency of power transmission and avoiding additional transmission losses and backlashes. The bushing 252 provides stable rotational support for the synchronous belt drive shaft 251. By fixing it to the housing 210, the radial and axial displacement of the synchronous belt drive shaft 251 can be effectively limited, thereby ensuring the operating accuracy and long-term stability of the drive system.

[0034] like Figure 3 , Figure 6 As shown, this application further proposes the following technical solutions. The slider 230 also includes a support shaft 231, which is vertically fixed to the front end face of the slider 230. One end of the first cantilever 310 is rotatably connected to the support shaft 231 via a bearing. The cylinder of the transverse drive device 330 is hinged to the side wall of the first cantilever 310, and the piston rod is hinged to the side wall of the second cantilever 320. The cylinder of the vertical drive device 340 is fixed to the bottom of the second cantilever 320, and its output end is connected to the vibrating rod head 430. A guide key and a keyway are provided between the first cantilever 310 and the second cantilever 320. The guide key is fixed to the outer wall of the first cantilever 310, and the keyway is provided to the inner wall of the second cantilever 320. The two cooperate to restrict the relative rotation of the first cantilever 310 and the second cantilever 320.

[0035] Specifically, the support shaft 231, as a key connecting component between the slider 230 and the vibration position drive mechanism 300, provides a stable vertical support point. It is vertically fixed to the front end face of the slider 230, ensuring that the vibration position drive mechanism 300 can be connected to the slider 230 with a defined reference point and providing a pivot for subsequent rotational connections. The support shaft 231 can be a solid or hollow cylindrical rod, securely fixed to the front end face of the slider 230 by welding, bolting, or integral molding. Its material is typically high-strength steel to withstand the forces and torques generated by the vibration mechanism 400 during operation.

[0036] One end of the first cantilever 310 is rotatably connected to the support shaft 231 via a bearing. This connection allows the first cantilever 310 to rotate around the support shaft 231, thus providing the vibrating mechanism 400 with a certain degree of swing freedom. One end of the first cantilever 310 is usually designed with a hole, the bearing is installed in the hole, and the support shaft 231 passes through the inner ring of the bearing, thereby achieving the rotatable connection.

[0037] The cylinder of the lateral drive device 330 is hinged to the side wall of the first cantilever 310, and the piston rod is hinged to the side wall of the second cantilever 320. The lateral drive device 330 is used to achieve lateral displacement of the second cantilever 320 relative to the first cantilever 310. By hinged the cylinder and piston rod to the two cantilever arms respectively, the lateral drive device 330 can precisely control the lateral position of the second cantilever 320 by pushing and pulling, thereby adjusting the lateral vibration range of the vibrator head 430. The lateral drive device 330 can be a hydraulic cylinder, a pneumatic cylinder, or an electric actuator, preferably a servo electric actuator.

[0038] The cylinder of the vertical drive device 340 is fixed to the bottom of the second cantilever 320, and its output end is connected to the vibrating rod head 430. The vertical drive device 340 is responsible for driving the vibrating rod head 430 to perform vertical insertion and extraction actions. Fixing its cylinder to the bottom of the second cantilever 320 ensures that the force transmission path between the vertical drive device 340 and the vibrating rod head 430 is direct and stable. The direct connection of the output end to the vibrating rod head 430 ensures that the driving force can be applied to the vibrating rod head 430 efficiently and accurately, achieving precise vertical motion control. The vertical drive device 340 adopts an electrically controlled adjustable speed servo electric actuator or a proportionally controlled hydraulic cylinder. Its core feature is that it can dynamically adjust the output speed and thrust according to the position of the vibrating rod head 430 in the circular trajectory, thereby outputting high-speed, low-load motion during the insertion phase and low-speed, high-load motion during the extraction phase. The cylinder is firmly fixed to the bottom of the second cantilever 320 by bolts or welding. Its output end (such as the piston rod) is connected to the upper end of the vibrating rod head 430 through threaded connection, pin connection or flange connection.

[0039] A guide key and a keyway are provided between the first cantilever 310 and the second cantilever 320. The guide key is fixed to the outer wall of the first cantilever 310, and the keyway is located on the inner wall of the second cantilever 320. The combination of the guide key and keyway restricts the relative rotation between the first cantilever 310 and the second cantilever 320. The cooperation of the guide key and keyway is the key structure to prevent relative rotation between the first cantilever 310 and the second cantilever 320. The guide key is typically a long strip structure with a rectangular or trapezoidal cross-section, fixed to the outer wall of the first cantilever 310 by bolts or welding. The keyway is a groove machined into the inner wall of the second cantilever 320 that matches the shape of the guide key. When the second cantilever 320 is fitted onto the first cantilever 310, the guide key slides into the keyway, allowing relative linear sliding between the two cantilever arms, but preventing relative rotation.

[0040] like Figure 6 As shown, this application further proposes that the hose 420 of the vibration mechanism 400 is a flexible transmission shaft, one end of which is connected to the output shaft of the vibration motor 410, and the other end is connected to the vibration rod head 430; the vibration rod head 430 is fixedly connected to the output end of the vertical drive device 340.

[0041] Specifically, the hose 420 is a flexible drive shaft. A flexible drive shaft is a mechanical component capable of transmitting torque and rotational motion while allowing a certain degree of bending and displacement. It is typically made of multiple layers of high-strength steel wire or metal strip spirally wound, and externally wrapped with a wear-resistant and oil-resistant protective sleeve to prevent dust and moisture intrusion and provide additional support and protection. This structure allows the flexible drive shaft to transmit the rotational power of the vibratory motor 410 while accommodating the vertical movement of the vibratory rod head 430 and the relative lateral displacement between the first cantilever 310 and the second cantilever 320, ensuring the continuity and stability of power transmission.

[0042] In some embodiments of this application, the vibratory motor 410 and vertical drive device 340 in the vibratory mechanism 400 circulate on the annular guide rail 220, requiring a continuous power supply. However, if a traditional cable power supply method is used, the cable is prone to tangling and wear as the slider 230 circulates, which may even limit the range of motion of the slider 230, affecting the continuous and stable operation of the equipment and the convenience of maintenance.

[0043] In this application, the device further includes a seamless annular sliding contact line 270, a current collector 280, and an intermediate power supply 290. The seamless annular sliding contact line 270 is a conductive device for providing continuous power to mobile equipment. It is typically made of conductive material, such as copper or aluminum alloy, and designed in an annular structure to accommodate the cyclic movement path of the slider 230. The sliding contact line can employ a multi-pole design to provide power at different voltages or phases. The seamless annular sliding contact line 270 is fixed to the outer wall of the housing 210 and arranged around the annular guide rail 220, ensuring continuous contact with the current collector 280 on the slider 230. The current collector 280 is a device for obtaining electrical energy from the seamless annular sliding contact line 270. It typically consists of components such as conductive brushes, conductive blocks, or rollers, which maintain sliding contact with the sliding contact line 270, thereby transferring electrical energy to the electrical equipment on the slider 230. The current collector 280 is fixed to the slider 230 and electrically connected to the seamless annular sliding contact line 270, enabling real-time power transmission. The intermediate power supply unit 290 connects the external power source to the seamless annular sliding contact line 270. It includes components such as a transformer, rectifier, voltage regulator, or overload protection circuit, converting the external power into the voltage and current required by the internal electrical equipment of the sliding contact line system and vibrating machinery, and providing necessary protection functions. The intermediate power supply unit 290 is electrically connected to both the seamless annular sliding contact line 270 and the external power source, serving as the hub of the entire power supply system.

[0044] This power supply method completely avoids the problems of tangling, wear, and movement restrictions that can occur with traditional cable power supply, significantly improving the operational reliability and safety of the equipment. At the same time, since there is no need to frequently handle cable issues, the workload of equipment maintenance is greatly reduced, thus ensuring the continuous operation capability and overall operational efficiency of the mobile concrete continuous vibrating machine.

[0045] This application further proposes a scheme to optimize the vibration effect and operational stability, specifically including: multiple vibrating rod heads 430 are distributed at equal intervals along the horizontal direction on the bottom straight guide rail 221 section; the front semicircular guide rail 223 and the rear semicircular guide rail 224 have the same radius of curvature, and are connected to the bottom straight guide rail 221 and the top straight guide rail 222 by a smooth arc transition.

[0046] Specifically, multiple vibratory heads 430 are evenly distributed horizontally along the bottom straight guide rail 221 section to ensure uniform coverage within the concrete vibration area, avoiding missed or repeated vibrations. This is achieved through precise design of the number of sliders 230, the fixed spacing of the sliders 230 on the timing belt 240, and the length of the annular guide rail 220. The front semicircular guide rail 223 and the rear semicircular guide rail 224 have the same radius of curvature, ensuring symmetrical and smooth movement trajectories of the vibratory head 430 as it enters and exits the bottom and top straight guide rails 221 and 222 within the circular path of the annular guide rail 220. The front and rear semicircular guide rails 223 and 224 are smoothly connected to the bottom and top straight guide rails 221 and 222 via a circular arc, eliminating abrupt changes in movement at the connection points between the straight and circular guide rails, ensuring the continuity and smoothness of its movement trajectory. Using a smooth arc transition connection means that at the connection point between the straight guide rail and the arc guide rail, the tangent direction of the guide rail is continuous, without any sharp corners.

[0047] The working principle of the walking-type continuous concrete vibrating machine of the present invention is as follows: The whole machine moves at a constant speed above the ground tracks preset on both sides of the concrete pouring area via the walking mechanism 100. The walking mechanism 100 includes a frame 130, a track 110, a first drive wheel 120, a first driven wheel 150, and a drive motor 140. The track 110 is driven by the drive motor 140 to rotate the first drive wheel 120, thereby driving the whole machine to move stably over the newly poured concrete area and avoiding disturbance to the surface of the unset concrete. The circular track mechanism 200 is fixed on the frame 130. Its circular guide rail 220 is composed of a bottom straight guide rail 221, a top straight guide rail 222, a front semicircular guide rail 223, and a rear semicircular guide rail 224 forming a closed loop. Multiple sliders 230 circulate along the circular guide rail 220. The slider 230 rolls against both sides of the annular guide rail 220 via rollers 232 at its bottom, ensuring smooth operation. One end of the connecting seat 233 is fixed to the slider 230, and the other end is hinged to the synchronous belt 240 via a pin, allowing the slider 230 to move synchronously with the synchronous belt 240. The synchronous belt 240 is driven by a synchronous belt drive assembly, which includes a second drive wheel 250, a second driven wheel 260, a synchronous belt drive shaft 251, and a bushing 252. The second drive wheel 250 is connected to the first drive wheel 120 via a chain drive mechanism 160. Since the sprocket pitch circle diameters are the same, the linear velocity of the synchronous belt 240 is consistent with the traveling linear velocity of the track 110, thereby ensuring that the vibrator head 430 remains stationary relative to the concrete surface below on the bottom straight guide rail 221 section, achieving effective vibration.

[0048] During the machine's movement, multiple vibrating mechanisms 400 circulate along the annular guide rail 220 with the slider 230. Each vibrating mechanism 400 performs different actions in different sections: when the vibrating head 430 reaches the area where the front semicircular guide rail 223 connects to the bottom straight guide rail 221, the vertical drive device 340 initiates a rapid descent program, driving the vibrating head 430 to insert into the concrete at high speed to reduce disturbance to the concrete structure; after entering the bottom straight guide rail 221 section, the vibrating head 430 remains relatively stationary with respect to the concrete, and the vibrating motor 410 continuously drives the vibrating head 430 to rotate through the hose 420. The vibrating rod head 430 moves to the area where the rear semicircular guide rail 224 connects to the bottom straight guide rail 221. The vertical drive device 340 switches to a low-speed upward mode, so that the vibrating rod head 430 is slowly pulled out to avoid forming voids or cracks. Then the vibrating rod head 430 enters the top straight guide rail 222 section. In this section, the vibrating motor 410 stops, and the vibrating rod head 430 returns to the area of ​​the front semicircular guide rail 223 with the slider 230, ready for the next insertion. This enables multiple vibrating rod heads 430 to work in turn and continuously, effectively avoiding the overheating problem caused by the long-term operation of a single vibrating unit.

[0049] To achieve precise timing control of the aforementioned actions, the device incorporates multiple position sensors at key locations on the annular guide rail 220: a first proximity switch S1 is installed at the connection between the front semicircular guide rail 223 and the bottom straight guide rail 221 to trigger the rapid insertion of the vibrating rod head 430; a second proximity switch S2 is installed at the connection between the end of the bottom straight guide rail 221 and the rear semicircular guide rail 224 to trigger the slow withdrawal; and a third proximity switch S3 is installed at the beginning of the top straight guide rail 222 to stop the vibrating motor 410 and prepare for the next cycle. The control system receives these position signals and, in conjunction with the running speed and phase of the synchronous belt 240, dynamically adjusts the output speed and direction of the vertical drive device 340 and controls the start and stop of the vibrating motor 410. Furthermore, the lateral drive device 330 can adjust the lateral displacement of the second cantilever 320 relative to the first cantilever 310 according to construction requirements, thereby adjusting the lateral working range of the vibrating rod head 430. This adjustment is also executed by the controller based on preset parameters or external input commands.

[0050] Furthermore, the device is equipped with a vibration time control module, used to control the vibration time parameters corresponding to the concrete mix proportions. t The machine's travel speed is dynamically adjusted. Before construction, the operator inputs the corresponding vibration time t into the control system according to the concrete mix proportion. This time parameter can be preset. SWI -Relationship between vibration time and vibration time t = k·SWI + b The calculations are obtained. Based on this, the control system determines the minimum time that slider 230 needs to stay on the bottom straight guide rail 221 section, and then calculates the overall traveling speed of the machine. v = L / t ,inL The effective vibration length of the bottom straight guide rail 221 is specified. The speed of the drive motor 140 is adjusted by a frequency converter or servo drive, causing the track 110 to move at a certain speed. v As the vibrator moves, the synchronous belt 240 runs synchronously at the same linear speed, thus ensuring that the time during which the vibrator head 430 remains relatively stationary with the concrete on the bottom straight guide rail 221 section exactly meets the requirement. t The control logic achieves closed-loop matching between vibration time and walking speed, ensuring optimal vibration results for concrete with different rheological properties.

[0051] The current collector 280 on the slider 230 draws power along the seamless annular sliding contact line 270, providing a continuous and stable power supply to the vibratory motor 410, vertical drive device 340, horizontal drive device 330, position sensor and control system, avoiding the problem of traditional cable entanglement and ensuring continuous, efficient and reliable operation of the whole machine.
