Abstract
Description
Technical Field
[0001] This utility model relates to the field of warning device technology, and more specifically, it relates to a safety warning device for road rollers. Background Technology
[0002] While existing safety warning devices used on road rollers can provide some level of alertness and warning, their structural design is generally flawed, particularly in terms of the ease of angle adjustment and installation / removal. Current warning devices typically employ a fixed installation structure, requiring manual adjustment with tools. This process is not only cumbersome but also severely limited in the high-vibration, dusty, and noisy environment of construction sites. Operators often need to stop the machine to make adjustments, which not only delays construction progress but may also result in inaccurate coverage of the warning area due to delayed angle adjustments, thus reducing the effectiveness of safety warnings.
[0003] Meanwhile, existing safety warning devices also present inconveniences in terms of installation and disassembly. Most devices are fixed to the top of the roller body or cab using bolts or welding. The installation process requires the use of various tools and even multiple workers, which is time-consuming and labor-intensive. There are also certain safety risks when operating at heights. Disassembly is equally complicated. It not only requires disconnecting the power or signal lines, but also easily causes cable damage or loosening of the interfaces, affecting subsequent use. Due to the lack of modular and standardized design, there is poor compatibility between different models of rollers or warning devices. Installation often requires additional modification or custom-made connectors, further increasing the cost of use and maintenance difficulty. Utility Model Content
[0004] In view of the problems existing in the prior art, this utility model provides a safety warning device for road rollers to solve the technical problems mentioned in the background art, such as the inconvenience of adjusting the angle of the warning device and the inconvenience of installing and disassembling the warning device.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a safety warning device for a road roller, comprising a mounting base, a rotation adjustment mechanism, a quick installation mechanism, and an installation auxiliary mechanism. The rotation adjustment mechanism includes a base and a rotating disk. The base is mounted on one end face of the mounting base, and the rotating disk is rotatably mounted on the base. An arc groove is formed on the rotating disk. A locking bolt is installed on the base, which can pass through the arc groove and the base to fix the rotating disk on the base. The quick installation mechanism includes a clamping tube and a clamping rod. A clamping groove is formed on the outer wall of the clamping tube. A clamping block and a push rod are rotatably mounted on the outer wall of the clamping rod, and the push rod and the clamping block are slidably connected. A push spring is installed between one end of the push rod and the outer wall of the clamping rod, and the push spring pushes the clamping block into the clamping groove. A moving ring is slidably mounted longitudinally on the outer wall of the clamping tube, and a push-receiving slope block is installed at the bottom end of the moving ring.
[0006] The present invention is further configured such that the installation auxiliary mechanism includes a double-layer clamping ring and an outer rotating ring. The outer rotating ring is rotatably mounted on the outer wall of the clamping tube, and the double-layer clamping ring is fixedly mounted on the outer wall of the clamping tube. The double-layer clamping ring has a positioning hole, and the outer rotating ring is equipped with a bidirectional spring block. The bidirectional spring block is embedded into the positioning hole in stages to make the outer rotating ring rotate stably. A swivel block is installed on one end face of the outer rotating ring. The swivel block pushes the pushed swivel block to move the moving ring.
[0007] The present invention is further configured such that an installation plate is mounted on the rotating disk, and a warning light assembly is mounted on the installation plate. The warning light assembly is mounted on the installation plate to provide a safety warning lighting function when the road roller is operating.
[0008] The present invention is further configured such that the moving ring presses against the locking block, thereby fixing the locking block in the slot. The locking block is rotatably mounted on the outer wall of the locking rod and slides in cooperation with the push rod. Under the drive of the push spring, it is pushed into the slot to achieve quick locking.
[0009] The present invention is further configured such that an unlocking sleeve is longitudinally slidably installed on the outer wall of the card tube, and the unlocking sleeve can press against the card block, so that the card block is inserted back into the card connecting rod.
[0010] The present invention is further configured such that a screw plate is fixedly installed on one end face of the mounting base, and the snap-fit rod is threadedly fixedly connected to the screw plate. The screw plate is fixedly installed on one end face of the mounting base and threadedly fixedly connected to the snap-fit rod, providing a reliable foundation for threaded connection.
[0011] The present invention is further configured such that a retraction groove is provided on the outer wall of the locking rod, and the locking block and the push rod can be embedded in the retraction groove. The retraction groove allows the locking block and the push rod to be embedded and retracted, thereby realizing the withdrawal and reset of the locking block.
[0012] The present invention is further configured such that external bolt holes are provided around the mounting base, and external bolts pass through the external bolt holes to fix the mounting base in the required position. The mounting base provides a fixed connection foundation for the warning device and the road roller.
[0013] Compared with the prior art, this utility model provides a safety warning device for road rollers, which has the following beneficial effects: This utility model is equipped with a rotation adjustment mechanism. The base is installed on one end face of the mounting base, and the rotating disk is rotatably installed on the base and equipped with a warning light assembly. The orientation angle of the warning light can be adjusted by rotating the rotating disk. The arc groove on the rotating disk allows free rotation within a certain range. After adjustment, the locking bolt passes through the arc groove and the base to fix and lock the rotating disk. This realizes multi-angle flexible adjustment and stable fixation of the warning light assembly, ensuring that the warning light can adjust its orientation according to the road roller's operating direction and environmental needs, and providing an effective safety warning coverage range.
[0014] This utility model features a quick-installation mechanism. The snap-fit rod is threadedly fixed to the screw plate. A snap-fit block and push rod are rotatably mounted on the outer wall of the snap-fit rod. A push spring provides elastic driving force. When the snap-fit tube is inserted into the snap-fit rod, the push spring automatically pushes the snap-fit block out and into the slot to achieve quick snap-fit fixation. The moving ring slides longitudinally and presses against the snap-fit block to stably fix it in the slot. When disassembly is required, the unlocking sleeve presses against the snap-fit block to retract it into the slot and exit the slot. This enables quick installation and disassembly of the warning device without the need for complex tools, significantly improving equipment installation efficiency and maintenance convenience. It is particularly suitable for the rapid deployment needs of road roller operation sites.
[0015] This utility model features an installation auxiliary mechanism. The outer rotating ring is rotatably mounted on the outer wall of the clamping tube. The bidirectional spring blocks on the outer rotating ring are progressively embedded into the positioning holes on the double-layer clamping ring during rotation, providing graded positioning feedback and rotational stability. When the outer rotating ring rotates, the rotating ramp pushes the pushed ramp, converting the rotational motion into the longitudinal sliding of the moving ring. The moving ring presses against the clamping block to achieve locking. The precise positioning of the moving ring and the reliable locking of the clamping block can be achieved through a simple rotation operation. The positioning holes provide clear feedback to ensure that the quick installation mechanism is locked in place, preventing the clamping block from loosening or accidentally falling off, thus improving the reliability and safety of the warning device installation.

[0021] Please see Figures 1-5 A safety warning device for a road roller includes a mounting base 1, a rotation adjustment mechanism, a quick installation mechanism, and an installation auxiliary mechanism. The rotation adjustment mechanism includes a base 2 and a rotating disk 3. The base 2 is mounted on one end face of the mounting base 1, and the rotating disk 3 is rotatably mounted on the base 2. The rotating disk 3 has an arcuate groove 4. A locking bolt 5 is installed on the base 2. The locking bolt 5 can pass through the arcuate groove 4 and the base 2 to fix the rotating disk 3 on the base 2. The quick installation mechanism includes a clamping tube 6 and a clamping rod 7. The outer wall of the clamping tube 6 has a clamping groove 8. The outer wall of the clamping rod 7 has a clamping block 9 and a push rod 10 rotatably mounted, and the push rod 10 and the clamping block 9 are slidably connected. A push spring 11 is installed between one end of the push rod 10 and the outer wall of the clamping rod 7. The push spring 11 pushes the clamping block 9 into the clamping groove 8. A moving ring 12 is slidably mounted longitudinally on the outer wall of the clamping tube 6. A push-receiving slope block 13 is installed at the bottom end of the moving ring 12.
[0022] In this embodiment, the rotating disk 3 is rotatably mounted on the base 2. By rotating the rotating disk 3, the orientation angle of the mounting plate 19 and the warning light assembly 20 mounted on it can be adjusted. The arc groove 4 on the rotating disk 3 allows the rotating disk 3 to rotate freely within a certain angle range. After adjusting to the required angle, tighten the locking bolt 5 so that it passes through the arc groove 4 and the base 2, locking the rotating disk 3 onto the base 2. This achieves multi-angle adjustment and stable fixation of the warning light assembly 20, ensuring that the warning light can provide effective warnings in different directions according to the operational needs. The snap-fit rod 7 is threadedly fixed to the screw plate 22 on one end face of the mounting base 1. The outer wall of the snap-fit rod 7 is rotatably mounted. There is a locking block 9 and a push rod 10. A push spring 11 is installed between one end of the push rod 10 and the outer wall of the locking rod 7. During installation, the locking tube 6 is inserted into the locking rod 7. The push spring 11 pushes the locking block 9 outward through the push rod 10. The locking block 9 is pushed into the slot 8 opened in the outer wall of the locking tube 6 to achieve quick locking and fixation. The moving ring 12 slides longitudinally to the position of the locking block 9 and presses against the locking block 9 to make the locking block 9 stably fixed in the slot 8 to prevent loosening. When disassembly is required, the unlocking sleeve 21 slides longitudinally and presses against the locking block 9 to overcome the elasticity of the push spring 11 and make the locking block 9 and the push rod 10 fit back into the retraction slot 23 opened in the outer wall of the locking rod 7. The locking block 9 exits the slot 8 to release the locking and the locking tube 6 can be quickly disassembled.
[0023] The installation auxiliary mechanism includes a double-layer clamping ring 14 and an outer rotating ring 15. The outer rotating ring 15 is rotatably mounted on the outer wall of the clamping tube 6, and the double-layer clamping ring 14 is fixedly mounted on the outer wall of the clamping tube 6. The double-layer clamping ring 14 has a positioning hole 16. The outer rotating ring 15 is equipped with a bidirectional spring block 17, which is inserted into the positioning hole 16 in stages to make the outer rotating ring 15 rotate stably. A swivel block 18 is installed on one end face of the outer rotating ring 15. The swivel block 18 pushes the pushed swivel block 13 to move the moving ring 12.
[0024] In this embodiment, the outer rotating ring 15 is rotatably mounted on the outer wall of the clamping tube 6, and the double-layer clamping ring 14 is fixedly mounted on the outer wall of the clamping tube 6. The bidirectional spring block 17 on the outer rotating ring 15 is embedded into the positioning hole 16 opened on the double-layer clamping ring 14 in stages when the outer rotating ring 15 rotates, providing graded positioning feedback to make the outer rotating ring 15 rotate stably. When the outer rotating ring 15 rotates, the swivel block 18 on one end face pushes the push-receiving slope block 13 at the bottom end of the moving ring 12. Through the slope action, the rotational motion of the outer rotating ring 15 is converted into the longitudinal sliding motion of the moving ring 12. After the moving ring 12 moves longitudinally to the position of the clamping block 9, it presses against the clamping block 9, so that the clamping block 9 is fixed in the clamping groove 8. The longitudinal positioning of the moving ring 12 is achieved through the rotation operation, ensuring that the clamping block 9 is locked reliably. At the same time, the positioning hole 16 provides positioning feedback.
[0025] Please see Figures 1-5As a supplementary embodiment of a safety warning device for a road roller, which includes a rotation adjustment mechanism, a quick installation mechanism, and an installation auxiliary mechanism: A mounting plate 19 is installed on the rotating disk 3, and a warning light assembly 20 is installed on the mounting plate 19. The moving ring 12 presses against the locking block 9, so that the locking block 9 is fixed in the locking groove 8. An unlocking sleeve 21 is longitudinally slidably installed on the outer wall of the locking tube 6, and the unlocking sleeve 21 can press against the locking block 9, so that the locking block 9 is inserted back into the locking rod 7. A screw plate 22 is fixedly installed on one end face of the mounting base 1. The locking rod 7 is threadedly fixedly connected to the screw plate 22. A retraction groove 23 is opened on the outer wall of the locking rod 7, and the locking block 9 and the push rod 10 can be inserted into the retraction groove 23. External bolt holes 24 are opened around the mounting base 1, and external bolts pass through the external bolt holes 24 to fix the mounting base 1 in the required position.
[0026] More specifically, the mounting base 1 is fixed to the required position on the road roller by external bolts passing through the external bolt holes 24 opened around the perimeter. The base 2 is installed on one end face of the mounting base 1. The locking rod 7 is threadedly fixed to the screw plate 22 on one end face of the mounting base 1. During installation, the locking tube 6 is inserted into the locking rod 7, and the push spring 11 pushes the locking block 9 out and into the locking groove 8 to achieve quick locking. Rotating the outer rotating ring 15, the rotating ramp block 18 pushes the pushed ramp block 13 to make the moving ring 12 slide longitudinally and press against the locking block 9, thus stably locking the locking block 9 in the locking groove 8. The bidirectional spring block 17 is embedded step by step into the positioning hole 16 to provide rotation. With stability and proper feedback, after the locking mechanism is secured, the rotating disc 3 is rotated to adjust the orientation angle of the warning light assembly 20. After adjustment, the locking bolt 5 is tightened through the arc groove 4 to fix the rotating disc 3 onto the base 2. The warning light assembly 20 can then work normally to provide safety warnings. When disassembly is required, the longitudinally sliding unlocking sleeve 21 is pressed against the locking block 9 to make it retract into the return groove 23. The locking block 9 is then removed from the locking groove 8, allowing for quick disassembly of the locking pipe 6. This achieves rapid installation and disassembly of the warning device, flexible angle adjustment, and stable and reliable installation, significantly improving the installation efficiency and ease of use of the road roller safety warning device.
[0027] In summary, during the use or operation of the overall equipment: when the adjustment mechanism needs to be rotated, the rotating disk 3 is rotatably mounted on the base 2. By rotating the rotating disk 3, the orientation angle of the mounting plate 19 and the warning light assembly 20 mounted on it can be adjusted. The arc groove 4 on the rotating disk 3 allows the rotating disk 3 to rotate freely within a certain angle range. After adjusting to the required angle, tighten the locking bolt 5 so that it passes through the arc groove 4 and the base 2, locking the rotating disk 3 onto the base 2. This achieves multi-angle adjustment and stable fixation of the warning light assembly 20, ensuring that the warning light can provide effective warnings in different directions according to the needs of the operation.
[0028] When the mechanism needs to be installed quickly, the locking rod 7 is threadedly fixed to the screw plate 22 on one end face of the mounting base 1. The locking block 9 and push rod 10 are rotatably installed on the outer wall of the locking rod 7. The push spring 11 is installed between one end of the push rod 10 and the outer wall of the locking rod 7. During installation, the locking tube 6 is inserted into the locking rod 7. The push spring 11 pushes the locking block 9 outward through the push rod 10. The locking block 9 is pushed into the slot 8 opened on the outer wall of the locking tube 6 to achieve quick locking and fixing. The moving ring 12 slides longitudinally to the position of the locking block 9 and presses against the locking block 9 to make the locking block 9 stably fixed in the slot 8 to prevent loosening. When disassembly is required, the unlocking sleeve 21 slides longitudinally and presses against the locking block 9 to overcome the elasticity of the push spring 11 and make the locking block 9 and push rod 10 fit back into the retraction slot 23 opened on the outer wall of the locking rod 7. The locking block 9 exits the slot 8 to release the locking and the locking tube 6 can be quickly disassembled.
[0029] When the auxiliary mechanism needs to be installed, the outer rotating ring 15 is limited to rotate and installed on the outer wall of the clamping tube 6. The double-layer clamping ring 14 is fixedly installed on the outer wall of the clamping tube 6. The bidirectional spring block 17 on the outer rotating ring 15 is inserted into the positioning hole 16 opened on the double-layer clamping ring 14 in stages when the outer rotating ring 15 rotates, providing graded positioning feedback to make the outer rotating ring 15 rotate stably. When the outer rotating ring 15 rotates, the swivel block 18 on one end face pushes the push-receiving slope block 13 at the bottom of the moving ring 12. Through the slope action, the rotational motion of the outer rotating ring 15 is converted into the longitudinal sliding motion of the moving ring 12. After the moving ring 12 moves longitudinally to the position of the clamping block 9, it presses against the clamping block 9, so that the clamping block 9 is fixed in the clamping groove 8. The longitudinal positioning of the moving ring 12 is achieved through the rotation operation, ensuring that the clamping block 9 is locked reliably. At the same time, the positioning hole 16 provides positioning feedback.
[0030] Mounting base 1 is fixed to the required position on the road roller by external bolts passing through the external bolt holes 24 on all four sides. Base 2 is installed on one end face of mounting base 1. The locking rod 7 is threadedly fixed to the screw plate 22 on one end face of mounting base 1. During installation, the locking tube 6 is inserted into the locking rod 7, and the push spring 11 pushes the locking block 9 out and into the locking groove 8 to achieve quick locking. Rotating the outer rotating ring 15, the rotating ramp block 18 pushes the pushed ramp block 13 to make the moving ring 12 slide longitudinally and press against the locking block 9, so that the locking block 9 is stably locked in the locking groove 8. The bidirectional spring block 17 is embedded in the positioning hole 16 in stages to provide rotational stability. After the feedback and locking are completed, rotate the rotating disk 3 to adjust the orientation angle of the warning light assembly 20. After adjustment, tighten the locking bolt 5 through the arc groove 4 to fix the rotating disk 3 on the base 2. The warning light assembly 20 can then work normally to provide safety warnings. When disassembly is required, slide the unlocking sleeve 21 longitudinally and press it against the locking block 9 to make it retract into the return groove 23. The locking block 9 will then exit the locking groove 8, allowing for quick disassembly of the locking pipe 6. This achieves quick installation and disassembly of the warning device, flexible angle adjustment, and stable and reliable installation, significantly improving the installation efficiency and ease of use of the road roller safety warning device.
