Description

Technical Field

[0001] This utility model relates to the field of road maintenance equipment technology, and in particular to a compaction wheel for road surface sealing tape. Background Technology

[0002] Road maintenance is a key aspect of ensuring traffic safety and smooth flow. Repairing road surface cracks is a routine and important task. Currently, one of the widely used repair methods is the use of road surface crack sealing tape. After the crack sealing tape is applied to the crack surface, it needs to be compacted with a special compaction tool to ensure that it adheres tightly to the road surface, expels air, and thus achieves a long-lasting sealing and waterproofing effect.

[0003] Existing compaction tools are mostly simple hand-push compaction rollers with a fixed width. However, in actual construction, the width of road cracks is not constant and varies. When encountering a joint sealing strip that does not match the width of the compaction roller, operators often face a dilemma. If a compaction roller that is too narrow is used, multiple passes are required to cover the entire joint sealing strip, which is inefficient and can easily cause uneven compaction. If a compaction roller that is too wide is used, it may compact the road surface outside the joint sealing strip, affecting the construction quality.

[0004] To address this issue, some designs with replaceable wheels have emerged. However, most of these designs use bolts to connect the wheel to the bracket. In dusty outdoor construction sites, replacing the wheel requires carrying and using tools such as wrenches, which is not only cumbersome but also time-consuming. Small parts such as bolts and nuts are also easy to lose. If it is necessary to frequently replace compaction wheels of different specifications, this complicated replacement process affects the overall construction efficiency and restricts the rapid maintenance of the road surface.

[0005] Therefore, this utility model proposes a compaction wheel for road surface sealing tape to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of fixed compaction wheel specifications, poor adaptability, or complex structure, inconvenient disassembly and assembly, and time and labor-intensiveness when replacing different specifications of compaction wheels in the existing technology, this utility model aims to provide a compaction wheel for road surface sealing tape with improved structure that can effectively solve the above problems.

[0007] This utility model provides a compaction wheel for road surface sealing tape, including a fixing frame, a compaction wheel body, a fixing assembly including a first fixing block and a second fixing block, and a quick-release assembly.

[0008] The first fixing block is fixed to the fixing frame, the second fixing block is slidably connected to the compaction wheel body, and the first fixing block and the second fixing block can slide and separate from each other. The quick-release assembly includes a third fixing block fixedly connected to the first fixing block, a fourth fixing block fixedly connected to the second fixing block, and a second locking block slidably disposed in the third fixing block.

[0009] Furthermore, the fourth fixing block is provided with a slot, and the second locking block can move between a locked position that engages with the slot of the fourth fixing block and an unlocked position that is separated from the slot. By switching between the locked and unlocked positions of the second locking block, the first fixing block and the second fixing block can be quickly locked or separated, thereby achieving the purpose of quickly replacing the compaction wheel body.

[0010] Preferably, the compaction wheel for road surface sealing tape further includes a handle, a slide rod whose upper end is fixedly connected to the handle, a hollow fixing rod sleeved on the outside of the slide rod, and a limiting component disposed on the fixing rod. The bottom of the fixing rod is fixedly connected to the fixing frame. The limiting component is used to selectively lock the slide rod and the fixing rod. This structure allows the overall operating length of the device to be conveniently extended and retracted as needed.

[0011] Preferably, the quick-release assembly further includes a second spring and a fourth connecting block. The fourth connecting block is fixed inside the third fixing block, and the two ends of the second spring abut against the second locking block and the fourth connecting block respectively. This design utilizes the elastic force of the spring to make the second locking block tend to automatically reset to the locked position, simplifying the locking operation.

[0012] Preferably, the first fixing block is provided with a first sliding groove, and the second fixing block is fixed with a first locking block. The first locking block is slidably engaged in the first sliding groove. This guide rail-type engagement structure provides precise guidance for the relative sliding of the first fixing block and the second fixing block, ensuring the smoothness and stability of the disassembly and assembly process.

[0013] Preferably, the slide bar has multiple positioning holes arranged along its length direction. The limiting component includes a button, a limiting rod linked to the button, and a first spring. The limiting rod is used to selectively pass through the positioning holes on the fixed rod and the slide bar that are aligned with each other. It is a reliable gear-type locking structure that can achieve precise fixing of multiple lengths.

[0014] Preferably, the limiting component further includes a first connecting block and a second connecting block fixed to the outer wall of the fixing rod. The button is rotatably connected to the first connecting block through the second connecting block, providing stable support and rotation reference for the button's operation.

[0015] Preferably, a connecting rod is provided inside the second connecting block, and the button rotates around the connecting rod as an axis, thus defining the movement mode of the button.

[0016] Preferably, the limiting component further includes a third connecting block, which is fixed to the end of the button away from the first spring, while the limiting rod is fixed inside the third connecting block. This structure ensures that the rotation of the button can be accurately transmitted to the limiting rod, achieving reliable linkage.

[0017] Preferably, the first spring is disposed between the first connecting block and the pressing end of the button. When the button is pressed, the spring is compressed. After the button is released, the spring resets, causing the button and the limiting rod to reset, making the locking and unlocking operation of the entire length adjustment intuitive and effortless.

[0018] This utility model has the following beneficial effects: 1. This utility model solves the problem that existing compaction wheel tools have limited specifications, or that changing to different specifications of wheel bodies requires the use of tools and the removal and installation of screws, which is cumbersome, time-consuming and laborious. It achieves the technical effect of enabling the quick disassembly and installation of compaction wheel bodies of different specifications by hand, thus improving construction flexibility and work efficiency.

[0019] 2. This utility model solves the problem that traditional compaction tools have a fixed length, cannot adapt to the working habits of operators of different heights, or are difficult to operate flexibly in confined spaces such as under bridges or next to guardrails, by setting a limiting component consisting of a button, spring, connecting rod and limiting rod, and making it cooperate with multiple positioning holes on the sleeved sliding rod and fixed rod. It achieves the technical effect of being able to conveniently and quickly adjust the overall length of the device, enhancing the ergonomic performance and scene adaptability of the tool, and improving the operating comfort.

[0020] 3. This utility model solves the problems of existing tools having single functions, rigid design, and poor overall user experience by integrating a quick-release component that can quickly replace the compaction wheel with a limit component that can easily adjust the length. It achieves the comprehensive technical effect of making the whole device compact, functional, and user-friendly, and able to efficiently meet diverse road maintenance needs.

Detailed Implementation

[0023] 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.

[0024] Please refer to Figures 1 to 4 This utility model provides a compaction wheel for road surface sealing tape, which aims to solve the problems of inconvenient operation caused by the fixed length of existing compaction tools, and the single specification of compaction wheel and the cumbersome and time-consuming replacement process.

[0025] The compaction wheel for road surface sealing tape has an overall structure including a telescopic rod and a compaction wheel assembly installed at the bottom of the rod. Specifically, the device includes a handle 1, the upper end of a sliding rod 2 is fixedly connected to the handle 1, a hollow fixing rod 4 is sleeved on the outside of the sliding rod 2, the sliding rod 2 can slide along its length in the inner cavity of the fixing rod 4, thereby adjusting the overall length of the device, the bottom of the fixing rod 4 is fixedly connected to a fixing frame 5, and the compaction wheel body 6 is installed on the fixing frame 5 through a quick-release mechanism.

[0026] The mechanism for quickly replacing the compaction wheel body 6 is composed of a fixing component 7 and a quick-release component 8. The fixing component 7 includes a first fixing block 701 and a second fixing block 702. The first fixing block 701 is fixedly connected to the fixing frame 5, while the second fixing block 702 is slidably connected to the compaction wheel body 6. In order to guide and constrain the separation and closing of the two fixing blocks, a first sliding groove is provided on the first fixing block 701, while a first locking block 703 is fixed on the second fixing block 702. The first locking block 703 is slidably engaged in the first sliding groove.

[0027] The quick-release assembly 8 is used to lock or unlock the first fixing block 701 and the second fixing block 702. The quick-release assembly 8 includes a third fixing block 801, a fourth fixing block 802, and a second locking block 803. The third fixing block 801 is fixedly connected to the first fixing block 701, and the fourth fixing block 802 is fixedly connected to the second fixing block 702. The fourth fixing block 802 has a slot. The second locking block 803 is slidably disposed within the third fixing block 801. The second locking block 803 can move between two positions, the first being a locked position where it engages with the slot of the fourth fixing block 702. 701 and the second fixing block 702 are locked and cannot be separated. Another position is the unlocked position where they are separated from the slot. In this unlocked position, the second fixing block 702 can slide and separate from the first fixing block 701 along the direction of the first slide groove. In order to provide a reset spring force for the second locking block 803, the quick release assembly 8 also includes a second spring 804 and a fourth connecting block 805. The fourth connecting block 805 is fixed inside the third fixing block 801. The two ends of the second spring 804 abut against the second locking block 803 and the fourth connecting block 805 respectively, and continuously apply a pushing force towards the locked position to the second locking block 803.

[0028] The limiting component 3 is used to selectively lock and unlock the sliding rod 2 and the fixed rod 4. To achieve this function, multiple positioning holes are provided on the wall of the sliding rod 2 along its length. When the sliding rod 2 slides to a specific length in the fixed rod 4, a positioning hole on the sliding rod 2 can be aligned with a positioning hole on the fixed rod 4. The limiting component 3 includes a button 301, a first spring 302, a first connecting block 303, a second connecting block 304, a connecting rod 305, a third connecting block 306, and a limiting rod 307. The first connecting block 303 is fixed to the outer wall of the fixed rod 4 and serves as the mounting base for the entire limiting component 3. The second connecting block 304 is provided with a connecting rod 305. The button 301 is rotatably connected to the first connecting block 303 through the second connecting block 304 with the connecting rod 305 as the rotation axis. This connection method allows the button 301 to swing slightly around the connecting rod 305.

[0029] Meanwhile, the first spring 302 is disposed between the first connecting block 303 and the pressing end of the button 301, providing elastic force for the button 301 to reset. At the end of the button 301 away from the first spring 302, a third connecting block 306 is fixedly connected, and the limiting rod 307 is fixed inside the third connecting block 306 and extends toward the fixing rod 4. In the assembled state, when the button 301 is not pressed, the first spring 302 is in a naturally extended state, and its elastic force pushes the pressing end of the button 301, causing the button 301 to rotate around the connecting rod 305, and driving the third connecting block 306 and the limiting rod 307 at the other end, so that the limiting rod 307 passes through the positioning hole aligned on the fixing rod 4 and the slide rod 2, thereby locking the two together firmly and ensuring the length stability of the device during use.

[0030] Based on the above embodiments, the present invention may further include the following preferred technical solutions: In a preferred embodiment, in order to achieve automatic reset and reliable locking of the second locking block 803 in the quick-release assembly 8, the quick-release assembly 8 further includes a second spring 804 and a fourth connecting block 805. The fourth connecting block 805 is fixedly installed in the internal cavity of the third fixing block 801. The second spring 804 is disposed between the second locking block 803 and the fourth connecting block 805. The two ends of the second spring 804 abut against the inner side of the second locking block 803 and the outer side of the fourth connecting block 805, respectively. This structure ensures that the second spring 804 always applies an elastic thrust to the second locking block 803 in the direction of the fourth fixing block 802.

[0031] As another preferred embodiment, in order to ensure the stability and guidance of the first fixing block 701 and the second fixing block 702 during the sliding separation and merging process, a first sliding groove is provided on the side wall of the first fixing block 701 along the direction of its separation from the second fixing block 702. Correspondingly, a first locking block 703 is fixedly connected to the side wall of the second fixing block 702. The shape and size of the first locking block 703 are adapted to the first sliding groove, and it can be slidably accommodated in the first sliding groove in the assembled state. This sliding groove and sliding block cooperation structure provides precise guidance for the relative sliding of the two fixing blocks.

[0032] As a further optimization of the limiting component 3, in order to make the rotation of the button 301 more stable, the limiting component 3 also includes a second connecting block 304. The button 301 is rotatably connected to the first connecting block 303 through the second connecting block 304. A connecting rod 305 is also provided inside the second connecting block 304. The button 301 rotates around the axis of the connecting rod 305. This structure ensures smooth and reliable rotation.

[0033] As another preferred design for the limiting component 3, in order to achieve reliable linkage between the action of the button 301 and the action of the limiting rod 307, the limiting component 3 also includes a third connecting block 306. The third connecting block 306 is fixed on the end of the button 301 away from the first spring 302, while the limiting rod 307 is firmly fixed inside the third connecting block 306 and moves synchronously with it.

[0034] The working principle of the compaction wheel for road surface sealing tape of this utility model is as follows: When it is necessary to replace the compaction wheel body 6 with a different specification to adapt to road surface cracks of different widths, the operator first needs to press the second locking blocks 803 symmetrically arranged on both sides. Under the action of pressing pressure, the second locking blocks 803 overcome the elastic force of the second spring 804 and slide inward along the inner slide of the third fixing block 801 until they are completely disengaged from the slot of the fourth fixing block 802. At this time, the lock between the first fixing block 701 and the second fixing block 702 is released. Subsequently, the operator can remove the second fixing block 702 and the first locking block 702. Together, slide along the first groove on the first fixing block 701 until the two are completely separated, and the old compaction wheel body 6 can be removed. When installing the new compaction wheel body 6, simply align the first locking block 703 on the new second fixing block 702 with the first groove on the first fixing block 701 and slide it in. When the two fixing blocks are about to be completely fitted, the inclined surface of the second locking block 803 will contact the edge of the fourth fixing block 802 and automatically slide into the slot of the fourth fixing block 802 under the elastic force of the second spring 804, thus completing the quick locking.

[0035] When the overall length of the device needs to be adjusted according to the operator's height or the working environment, the operator presses the push end of button 301. The push end compresses the first spring 302, causing button 301 to rotate around the connecting rod 305. The third connecting block 306, which is fixed at the other end of button 301, rotates synchronously and drives the limiting rod 307 fixed inside it to be pulled out from the positioning holes that were originally aligned on the fixed rod 4 and the sliding rod 2. At this time, the lock between the sliding rod 2 and the fixed rod 4 is released. The operator can use the handle 1 to drive the sliding rod 2 to slide up and down along the inner wall of the fixed rod 4 to the appropriate target length. After releasing button 301, the compressed first spring 302 returns to its original shape. Its elastic force pushes button 301 to rotate in the opposite direction and reset, and drives the limiting rod 307 to be re-inserted into the other set of positioning holes that are now aligned, thereby quickly completing the length locking.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
