Description

Technical Field

[0001] This utility model relates to the field of hydraulic vibratory trolley front bar technology, specifically a hydraulic vibratory trolley front bar frame 360-degree rotator. Background Technology

[0002] Traditional vibration compaction methods are limited by dense reinforcement and irregularly shaped formwork in large concrete slabs, resulting in numerous dead corners, low efficiency of manual vibration, and high risks. Fixed-angle hydraulic rod supports can only swing vertically or slightly, leading to frequent downtime due to oil pipe bending, entanglement, and bursting. The third-generation trolley places the slewing support and central slewing joint at the front, giving the front rod support continuous circumferential freedom. The vibrator can reach any corner, while the oil circuit remains unobstructed and entanglement-free. Quick disassembly and assembly of interfaces reduce downtime for rod replacement. The enclosed protective cover and centralized lubrication reduce maintenance intensity. It has now been promoted in dams, inverts, trenches, pipe corridors, and other scenarios, achieving one-time molding and continuous operation, significantly shortening the construction period, improving quality, and reducing safety risks.

[0003] Traditional vibratory trolleys can only swing vertically or at a limited angle. When faced with complex formwork, densely packed reinforcement, or narrow spaces, the vibratory rod often cannot reach dead corners due to the limited angle, requiring manual supplementary vibration, which is inefficient and results in inconsistent quality. At the same time, the hydraulic oil pipes are easily tangled or even torn due to repeated bending during the swing, and downtime for maintenance slows down the construction period and increases costs. In addition, manually dragging cables and vibratory rods is labor-intensive and carries the risk of electric shock and mechanical injury. The root cause of the above defects is the lack of a rotating mechanism that can rotate continuously, keep the oil circuit unobstructed, and quickly dock with existing trolleys. Utility Model Content

[0004] The purpose of this invention is to provide a 360-degree rotator for the front bar frame of a hydraulic vibrating trolley, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a 360-degree rotator for the front bar frame of a hydraulic vibrating trolley, comprising an upper rotating support plate, a lower rotating support plate, a slewing support, a slewing drive motor, and a central slewing joint. The upper rotating support plate is fixed to the inner ring of the slewing support by bolts, and the lower rotating support plate is fixed to the outer ring of the slewing support by bolts. A gear is provided on the outer circumference of the outer ring and meshes with the pinion of the slewing drive motor. The rotating body of the central slewing joint is connected to the upper rotating support plate through an adapter joint. The fixed body of the central slewing joint is disposed in the lower rotating support plate and forms an anti-rotation fit with the upper rotating support plate through a stop pin.

[0006] As a further embodiment of this utility model: the upper plate of the rotating bracket is detachably connected to the excavator boom via a connecting pin and a pin fixing bolt.

[0007] As a further embodiment of this utility model: the lower plate of the rotating support is provided with connecting bolts for fixing to the hydraulic vibrator assembly.

[0008] As a further embodiment of this utility model: the rotary drive motor is fixed to the side wall of the upper plate of the rotary bracket by bolts, and its output shaft passes through the through hole of the upper plate of the rotary bracket and is connected to the pinion key.

[0009] As a further embodiment of this utility model: the fixing body of the central rotary joint is locked in the inner cavity of the lower plate of the rotating bracket by the fixing plate of the central rotary joint.

[0010] As a further embodiment of this utility model: a front guard and a slewing support guard are installed between the upper plate of the rotating bracket and the lower plate of the rotating bracket to enclose and protect the slewing support.

[0011] As a further embodiment of this utility model: the upper plate of the rotating bracket is provided with a grease nipple, which is connected to the oil passage of the rotary support for adding lubricating grease.

[0012] As a further embodiment of this utility model: one end of the stop pin is fixed to the fixing body of the central rotary joint, and the other end is inserted into the corresponding hole of the upper plate of the rotating bracket to prevent the fixing body from rotating with the lower plate of the rotating bracket.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: By coaxially integrating the slewing support, hydraulic motor and central slewing joint, the front bar frame can rotate continuously 360° in the horizontal plane, and the vibrating rod can flexibly extend into any corner, eliminating the need for manual vibration. Construction efficiency and concrete compaction uniformity are improved simultaneously. The central slewing joint provides an independent channel for the oil circuit throughout the rotation, completely avoiding oil pipe entanglement and breakage, and significantly extending the equipment's trouble-free operation time. The upper and lower plates of the rotating support are rigidly connected to the trolley boom and vibrating rod respectively. Installation and disassembly use the original pin and bolt method, and can be directly replaced without modifying the main unit. The overall structure is compact, the weight increase is limited, the trolley's mobility is not affected, and the enclosed cover and centralized lubrication design reduce the workload of on-site maintenance. Workers can switch from directly holding the rod to remote control operation, reducing labor intensity and safety hazards simultaneously. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-2 In this embodiment of the utility model, the 360-degree rotator of the front rod frame of the hydraulic vibrating trolley includes an upper rotating bracket 4, a lower rotating bracket 11, a rotary support 13, a rotary drive motor 3, and a central rotary joint 9. The upper rotating bracket 4 and the inner ring of the rotary support 13 are fixed by bolts, and the lower rotating bracket 11 and the outer ring of the rotary support 13 are fixed by bolts. The outer ring is provided with gears on its outer circumference and meshes with the pinion 2 of the rotary drive motor 3. The rotating body of the central rotary joint 9 is connected to the upper rotating bracket 4 through an adapter joint 10. The fixed body of the central rotary joint 9 is set in the lower rotating bracket 11 and forms an anti-rotation fit with the upper rotating bracket 4 through a stop pin 15.

[0017] Preferably, the upper plate 4 of the rotating support is detachably connected to the excavator boom via connecting pin 1 and pin fixing bolt 6, requiring no welding or modification on site and significantly shortening replacement time. The lower plate 11 of the rotating support is directly locked to the vibrator assembly with connecting bolt 6, rigidly transmitting vibration energy and achieving sufficient vibration depth. The rotating drive motor 3 is mounted against the wall with connecting bolt 6, and its output shaft passes through the through hole of the upper plate and connects to the pinion key, resulting in rapid rotation response and eliminating dead angles in one go. The fixing body of the central rotary joint 9 is pressed tightly into the inner cavity of the lower plate by the fixing plate. The entire hydraulic circuit is independent, completely eliminating the need for winding around the upper plate of the rotating support. The front guard 7 between the upper and lower plates and the guard of the slewing support 13 are sealed together, isolating the concrete slurry and extending the lubrication cycle. The oil circuit of the concentrated grease nipple 8 on the upper plate and the slewing support 13 is connected, allowing a single person to complete maintenance on the ground, reducing the risk of working at height. One end of the stop pin 15 is locked to the joint fixing body, and the other end is inserted into the positioning hole of the upper plate to prevent the fixing body from rotating with the lower plate. The hydraulic signal is always stable, the whole machine runs smoothly and reliably, and construction efficiency, quality and safety are improved simultaneously.

[0018] The working principle of this utility model is as follows: In use, first insert the connecting pin 1 into the hole of the excavator boom and lock it with the pin fixing bolt 5. The upper plate 4 of the rotating support is then integrated with the boom. Next, align the hydraulic vibrator assembly with the connecting bolt 6 of the lower plate 11 of the rotating support and tighten it. The entire machine is rigidly connected to the vibrator body. The hydraulic station supplies oil through the rotating body of the central rotary joint 9 into the fixed body. The oil circuit is constrained by the stop pin 15 and does not rotate with the lower plate 11 of the rotating support, achieving continuous oil delivery without entanglement. Start the rotary drive motor 3, whose output shaft drives the pinion 2 to mesh with the outer ring gear of the rotary support 13, driving the lower plate 11 of the rotating support. The vibrator rotates smoothly 360° around the axis of the slewing support 13, allowing it to reach any dead angle. The inner ring of the slewing support 13 is bolted to the upper plate 4 of the rotating bracket, and the outer ring is bolted to the lower plate 11 of the rotating bracket. When the inner and outer rings rotate relative to each other, the front guard 7 and the slewing support guard 14 seal the gap to prevent concrete slurry from entering. During the work interval, grease is injected into the slewing support 13 through the grease nipple 8 to keep it lubricated. If the vibrator needs to be replaced or the whole machine needs to be overhauled, it can be quickly replaced by simply loosening the connecting bolt 6 or pulling out the connecting pin 1. The whole process does not require additional welding or modification, saving time and effort in disassembly and assembly, and ensuring high efficiency for continuous operation.

[0019] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
