Description

Technical Field

[0001] This utility model relates to the field of building construction equipment technology, and in particular to a concrete vibrator for channel lining. Background Technology

[0002] In the construction of canal linings for water conservancy projects, the density of concrete directly affects the canal's seepage prevention performance and service life. Currently, the compaction of concrete mainly relies on vibratory compactors. Common concrete vibratory compactors typically consist of a power source, a flexible shaft, and vibrating rods. The power source drives the vibrating rods through the flexible shaft to generate high-frequency vibrations, thereby expelling air bubbles from the concrete and making it denser.

[0003] However, in actual canal lining construction, canals are often long and narrow, and the lining work surface is usually in the open air. The work path is long, and the construction environment is relatively complex. In actual construction, this traditional vibratory compaction equipment relies mainly on operators holding the vibratory hose for extended periods. Because the vibratory hose and vibrator themselves have a certain weight and generate continuous, strong vibrations during operation, operators not only need to bear the weight of the equipment but also overcome the reaction force from the vibration. Maintaining this handheld posture for a long time easily leads to muscle soreness and exhaustion in the operator's arms, severely affecting the continuity of work and construction efficiency. Furthermore, this method of operation, relying solely on arm strength, makes it difficult to maintain the stability of the vibrator's position for extended periods, easily causing uneven compaction and affecting construction quality.

[0004] Therefore, this utility model proposes a concrete vibrator for channel lining to address the shortcomings of existing technologies. Utility Model Content

[0005] In view of the problems of high labor intensity, rapid physical exertion and poor operational stability when manually operating concrete vibrating equipment in the prior art, this utility model aims to provide a channel lining concrete vibrating machine with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a channel lining concrete vibrator, comprising: an engine, a vibrating hose connected to the output end of the engine, and a vibrating rod connected to the end of the vibrating hose away from the engine; it also includes a carrying mechanism disposed on the outside of the vibrating hose and a splash-proof mechanism disposed on the end of the vibrating rod.

[0007] The carrying mechanism includes a first mounting block, a second mounting block, and a connecting strap. The first and second mounting blocks are fixedly surrounding the outer surface of the vibrating hose. The connecting strap connects to the outer surfaces of the first and second mounting blocks to transfer the equipment load to the user's back. The splash-proof mechanism includes a fixed plate, a fixed ring, a slide rail, a connecting ring, a first connecting rod, a second connecting rod, and a connecting cloth. The fixed plate and the fixed ring are fixedly connected to the outer surface of the vibrating rod. The slide rail is axially fixed between the fixed plate and the fixed ring, and the connecting ring is slidably connected to the outer surface of the slide rail. The first connecting rod is rotatably connected to the fixed plate, and the second connecting rod is rotatably connected to the connecting ring, with the second connecting rod hinged to the first connecting rod. The connecting cloth is sewn onto the outer side of the first connecting rod. The sliding of the connecting ring drives the linkage mechanism to move, thereby controlling the unfolding or retraction of the connecting cloth.

[0008] Preferably, in order to prevent the carrying mechanism from relative displacement on the vibrating hose, a plurality of locking blocks are fixedly connected to the outer surface of the vibrating hose along the axial direction. The inner walls of the first mounting block and the second mounting block are recessed and provided with locking grooves that are adapted to the locking blocks. The first mounting block and the second mounting block restrict their axial sliding and circumferential rotation on the vibrating hose through the tight fit between the locking grooves and the locking blocks.

[0009] Preferably, in order to facilitate the disassembly and fixing of the carrying mechanism, the outer side walls of the first mounting block and the second mounting block are both fixedly connected with a fixing block protruding outwards. A first bolt is provided between the two fixing blocks. The first bolt passes through and threadedly locks the two fixing blocks, thereby fastening the first mounting block and the second mounting block together.

[0010] Preferably, in order to improve carrying comfort and reduce vibration transmission, an airbag is fixedly connected to one side of the connecting strap away from the first mounting block and the second mounting block. The airbag extends along the length of the connecting strap to form a flexible buffer layer between the human back and the device.

[0011] Preferably, in order to achieve stable locking of the splash-proof mechanism in the deployed state, a limit block is fixedly connected to one end surface of the slide rail near the fixed plate, and a first fixing strip is fixedly connected to the outer side wall of the connecting ring. When the connecting ring slides to abut against the limit block, the first fixing strip is fixed to the limit block by a locking member.

[0012] Preferably, in order to achieve stable locking of the splash-proof mechanism in the stored state, a second fixing strip is fixedly connected to the outer wall of the fixing ring. The surface of the first fixing strip is provided with a through hole, and the side of the limiting block and the second fixing strip are provided with threaded holes. A second bolt passes through the first fixing strip and is screwed into the corresponding threaded hole to achieve dual-position locking.

[0013] Preferably, in order to prevent mud from leaking from the base of the anti-splash mechanism, a rubber ring is fitted on the outer surface of the vibrator between the fixed plate and the connecting cloth. The outer wall of the rubber ring is in close contact with the inner wall of the connecting cloth near the fixed plate to form an effective sealing structure.

[0014] This invention solves the problem of excessive physical exertion and arm pain caused by operators carrying heavy vibratory hoses for extended periods. It utilizes a detachable carrying mechanism consisting of a first mounting block and a second mounting block on the outside of the vibratory hose, and an airbag on the inside of the connecting strap. This achieves the technical effects of transferring the lifting load from the arms to the shoulders and back, using the airbag's cushioning effect to distribute pressure and isolate some high-frequency vibrations, effectively reducing labor intensity, improving operational comfort, and increasing continuous work efficiency. Furthermore, by installing a foldable splash-proof component consisting of a slide rail, connecting ring, first connecting rod, and second connecting rod at the end of the vibrator, in conjunction with the connecting cloth, it solves the problem of mud splashing outwards during concrete vibration, polluting the environment and operators' clothing. This achieves the technical effects of using a linkage mechanism to drive the connecting cloth to unfold and form a fan-shaped barrier, effectively blocking mud splashes, maintaining a clean working environment, and quickly folding it up to reduce volume when not in use, facilitating equipment transport and storage.

[0017] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0018] like Figure 1-4 As shown, the present invention provides a channel lining concrete vibrator, which aims to solve the technical problems in the prior art, such as the huge physical exertion caused by operators carrying the vibrating equipment for a long time, and the easy splashing of mud during concrete vibration operations, which pollutes the environment and the operator's clothing.

[0019] like Figure 1 and Figure 2 As shown, the main structure of the channel lining concrete vibrator includes an engine 1 and a vibrating hose 2 fixedly connected to the output end of the engine 1. The vibrating hose 2 serves as the power transmission medium, and a vibrating rod 3 is fixedly connected to the end of the hose away from the engine 1. The rotational power generated by the engine 1 during operation is transmitted to the vibrating rod 3 through the flexible shaft inside the vibrating hose 2, driving the vibrating rod 3 to generate high-frequency vibration to compact the concrete. In order to change the traditional purely hand-carrying operation method, a first mounting block 4 and a second mounting block 5 are detachably fixedly connected to the outer surface of the vibrating hose 2. After the first mounting block 4 and the second mounting block 5 are combined, they surround the outer perimeter of the vibrating hose 2. A ring-shaped connecting strap 10 is fixedly connected to the outer side of both the first mounting block 4 and the second mounting block 5. The connecting strap 10 is used for the operator to carry on their shoulders, thereby transferring the weight of the vibrating hose 2 and part of the vibrating rod 3 to the back and shoulders of the operator.

[0020] like Figure 1 , Figure 3 and Figure 4As shown, an openable splash-proof mechanism is provided at the end of the vibrating rod 3. A disc-shaped fixing plate 12 is fixedly connected to the outer surface of the end of the vibrating rod 3 near the vibrating hose 2. A fixing ring 18 is fixedly connected to the outer surface of the vibrating rod 3 on the side of the fixing plate 12 away from the vibrating hose 2. The fixing plate 12 serves as the front support base of the splash-proof mechanism, and the fixing ring 18 serves as the rear limiting base of the splash-proof mechanism. A slide rail 19 is fixedly connected axially between the fixing plate 12 and the fixing ring 18. A connecting ring 17 is slidably connected to the outer surface of the slide rail 19. The connecting ring 17 is located in the area between the fixing plate 12 and the fixing ring 18 and can reciprocate linearly along the slide rail 19. Several first connecting seats 13 are fixedly connected in a ring array on the outer surface of the fixing plate 12. The outer surface of the ring 17 is also fixedly connected with several second connecting seats 16 in a ring array. The first connecting seat 13 is rotatably connected to the first connecting rod 14 through a pin. The second connecting seat 16 is rotatably connected to the second connecting rod 15 through a pin. The end of the second connecting rod 15 away from the connecting ring 17 is rotatably connected to the middle of the first connecting rod 14 through a hinge or pin. The outer sides of the multiple first connecting rods 14 are jointly sewn with a flexible connecting cloth 25. The connecting cloth 25 covers the adjacent first connecting rods 14 in a fan shape or arc shape. When the connecting ring 17 slides, the second connecting rod 15 pushes or pulls the first connecting rod 14 to deflect, thereby causing the connecting cloth 25 to unfold or fold in an umbrella shape, thus forming a barrier above the working area of ​​the vibrator 3.

[0021] To address the aforementioned technical issues regarding carrying stability and ease of installation, this embodiment features a targeted design for the connection structure between the vibrating hose and the carrying mechanism.

[0022] like Figure 1 and Figure 2 As shown, a number of locking blocks 11 are fixedly connected to the outer surface of the vibrating hose 2 along the axial direction. These locking blocks 11 are distributed in rectangular or cylindrical protrusions to provide a positioning reference for the carrying mechanism and transmit axial load. Correspondingly, the inner walls of the first mounting block 4 and the second mounting block 5 are recessed and have slots 8 that are adapted to the shape and size of the locking blocks 11. During installation, the operator needs to align the first mounting block 4 and the second mounting block 5 and cover the outside of the vibrating hose 2, and make the slots 8 accurately engage with the corresponding outer surfaces of the locking blocks 11. Through the tight engagement of the slots 8 and the locking blocks 11, not only is the rapid positioning of the mounting blocks on the hose achieved, but the mechanical interlocking action also effectively restricts the axial displacement and circumferential rotation of the mounting blocks on the vibrating hose 2, ensuring a stable connection between the carrying system and the vibrating hose 2.

[0023] To further lock the first mounting block 4 and the second mounting block 5 in place, and keep them in an engaged state, the outer side walls of the first mounting block 4 and the second mounting block 5 are both fixedly connected with a fixing block 6. A first bolt 7 is provided between the two corresponding fixing blocks 6. The first mounting block 4 and the second mounting block 5 are fixedly connected by the first bolt 7 passing through and threadedly locking the two fixing blocks 6. This structure makes the disassembly and assembly process simple and quick, and the clamping force is adjustable.

[0024] In addition, to improve comfort when carrying the device and reduce the direct impact of equipment vibration on the human body, an airbag 9 is fixedly connected to the side of the connecting strap 10 away from the first mounting block 4 and the second mounting block 5, that is, the side that fits against the back of the human body. The airbag 9 extends along the length of the connecting strap 10. The gas filling the airbag 9 can form a flexible buffer layer between the back of the human body and the connecting strap 10, effectively dispersing the pressure brought by the weight of the device, and using the air damping characteristics to absorb part of the high-frequency vibration energy transmitted by the vibration hose 2.

[0025] Based on the above embodiments, this utility model also optimizes the positioning and sealing performance of the splash-proof mechanism, including the following specific technical solutions: As a preferred embodiment for locking the splash guard in its open / closed state, please refer to [the relevant documentation / reference]. Figure 3 and Figure 4 To ensure that the connecting cloth 25 remains stable during both the unfolding and splash protection operations and during storage and relocation, a limiting block 20 is fixedly connected to one end of the slide rail 19 near the fixed plate 12, a first fixing strip 21 is fixedly connected to the outer wall of the connecting ring 17, and a second fixing strip 22 is fixedly connected to the outer wall of the fixed ring 18.

[0026] Specifically, the side of the limiting block 20 and the side of the second fixing strip 22 are both provided with threaded holes with internal threads. The surface of the first fixing strip 21 is provided with a through hole, and a second bolt 23 is fitted on the first fixing strip 21. When it is necessary to keep the connecting cloth 25 unfolded, the connecting ring 17 is pushed until it touches the limiting block 20. At this time, the connecting ring 17 is screwed into the threaded hole of the limiting block 20 through the second bolt 23, thereby achieving a rigid fixed connection with the limiting block 20. Conversely, when it is necessary to retract the connecting cloth 25, the connecting ring 17 is pulled back to the fixing ring 18. At this time, the connecting ring 17 is screwed into the threaded hole of the second fixing strip 22 through the second bolt 23, thereby achieving a fixed connection with the fixing ring 18. This double-position locking structure effectively prevents the protective cover from accidentally retracting or unfolding due to vibration during vibration operation.

[0027] As another preferred embodiment for the sealing performance of the splash guard root, in order to prevent mud from leaking and splashing from the root gap where the connecting cloth 25 connects to the vibrator 3, please refer to... Figure 3 and Figure 4 A rubber ring 24 is fitted on the outer surface of the vibrating rod 3 between the fixed plate 12 and the connecting cloth 25. The rubber ring 24 is elastic and has sealing properties. The outer wall of the rubber ring 24 is in close contact with the inner wall of the end of the connecting cloth 25 near the fixed plate 12. The interference fit of the rubber ring 24 fills the gap between the rigid connector and the flexible cloth, forming an effective seepage barrier.

[0028] When using this utility model, the operator first prepares to wear it before channel lining operations. After starting the engine 1, the operator selects a suitable locking block 11 on the vibrating hose 2 according to the working posture requirements of the channel slope and bottom during channel lining construction, based on their own body type and operating habits. The first mounting block 4 and the second mounting block 5 are aligned and locked into the selected locking block 11. At this time, the locking block 11 and the locking groove 8 lock the installation position. Then, the first bolt 7 is tightened to clamp and fix the two mounting blocks. The operator carries the connecting strap 10 on their back and adjusts their carrying posture to adapt to the bending, side-turning and other working actions of channel lining. At this time, the airbag 9 fits against the back, using the air cushion effect to distribute the weight of the vibrating hose 2 and isolate the high-frequency vibration generated by the vibration operation. The load originally concentrated on the hands is transferred to the shoulders and back, significantly reducing the fatigue of the operator's arms and ensuring the comfort and stability of long-term operation in long-strip channel lining operations.

[0029] During the concrete vibration stage of the channel lining, power is transmitted to the vibrator 3 via the vibrating hose 2, causing it to vibrate at high frequency to break the flocculated structure of the concrete mixture and expel air bubbles. To meet the requirement of uniform concrete paving thickness during channel lining construction, the operator inserts the vibrator 3 into the lining concrete on the channel slope or bottom to the specified depth. To prevent concrete slurry from splashing and contaminating the channel lining construction surface or adhering to the equipment during vibration, the operator pushes the connecting ring 17 forward, causing it to slide along the slide rail 19 towards the vibrator 3. As the connecting ring 17 moves forward, the second connecting seat 16 on it... The second connecting rod 15 is pushed forward, which in turn pushes the first connecting rod 14 to rotate outward around the first connecting seat 13. When the connecting ring 17 touches the limiting block 20, the first connecting rod 14 is fully extended, causing the connecting cloth 25 to form an umbrella-shaped protective cover. At this time, the first fixing strip 21 is locked to the limiting block 20 by the second bolt 23 to keep the protective cover unfolded. The unfolded connecting cloth 25, together with the rubber ring 24 at the root, forms a closed area, effectively blocking the mud stirred up by the vibrator 3 during the channel lining vibration operation, and preventing the mud from affecting the surface flatness of the uncured lining concrete.

[0030] When the vibration operation of a section of the channel lining is completed or the site needs to be moved to the next construction area, loosen the second bolt 23, pull the connecting ring 17 backward, the second connecting rod 15 pulls the first connecting rod 14 inward, and the connecting cloth 25 folds accordingly. When the connecting ring 17 moves to the fixing ring 18, use the second bolt 23 again to lock the first fixing strip 21 onto the second fixing strip 22, thus completing the storage and fixing of the protective mechanism, reducing the space occupied by the equipment, and facilitating transportation and storage in the narrow channel construction area.
