[0002] Safety warning devices are also called construction signs, construction signs, and movable signs. They are used for peripheral protection reminders at road construction sites, maintenance of municipal construction, and construction. In order to ensure the normal construction of roads, provide safety warnings during road construction, and prevent the occurrence of safety accidents, people often use safety warning devices to warn people during road construction to prevent accidental collisions and reduce losses.

[0003] When the existing safety warning device for road construction is moved to a designated position for warning, each supporting leg provided at the bottom of the warning device often needs to be adjusted individually to support it on the ground, which makes the operation process more complicated and inconvenient to support and fix the safety warning device. Moreover, when the safety warning device is in use, it is easy to be blown down by strong winds. When the supporting ground is uneven, it is easy to cause the safety warning device to tilt or fall, making the support stability of the safety warning device poor, thus affecting the use of the safety warning device. In view of this, we propose a safety warning device for road construction. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figures 1 to 5As shown, the utility model provides a safety warning device for road construction, including a safety warning device body 1, a universal wheel 2 is symmetrically fixed by screws on the bottom of the safety warning device body 1, a first support plate 10 arranged in a rectangular shape is symmetrically welded on the bottom of the safety warning device body 1, a first connecting rod 5 and a second connecting rod 6 are respectively rotatably arranged between each two longitudinal first support plates 10 from left to right, and first rollers 9 are symmetrically fixed by screws at both ends of the first connecting rod 5 and the second connecting rod 6. When the pull rope 11 is used for a long time and is severely worn, the screws can be removed to facilitate the release of the pull rope 11 fixed on the first roller 9 and the re-fixation of the new pull rope 11. One end of the first connecting rod 5 passing through the first roller 9 is fixed to the output end of the motor 4 through a coupling, and the motor 4 is fixed to the safety warning device body 1 by screws. A support mechanism 3 located outside the universal wheel 2 is symmetrically fixed around the bottom of the safety warning device body 1;

[0028] The support mechanism 3 includes a first connecting plate 31 fixed to the safety warning device body 1 by screws, and a first spring 35 welded to the end of the first connecting plate 31 and welded to the second connecting plate 32. A support leg 33 is fixed to the end of the second connecting plate 32 by screws to facilitate replacement of the support leg 33 that is severely worn. A cone head 34 is slidably provided inside the support leg 33.

[0029] A pull rope 11 is fixed between the first roller 9 and the second connecting plate 32;

[0030] A first gear 7 is fixedly provided at the middle part of the first connecting rod 5 by screws, and a second gear 8 meshing with the first gear 7 is fixedly provided at the middle part of the second connecting rod 6 by screws. The interior of the supporting leg 33 is arranged as a cavity, and the cone head 34 abuts against the inner surface of the supporting leg 33. A second spring 36 is welded between the cone head 34 and the supporting leg 33. When not supported, the cone head 34 and the second spring 36 are located in the cavity of the supporting leg 33, and a fixing plate 39 for sliding of the cone head 34 is welded at the upper side end of the cone head 34. A through groove 310 matching with the fixing plate 39 is penetrated through the supporting leg 33, and the fixing plate 39 penetrates the through groove 310 transversely and extends to the outside.

[0031] Among them, the safety warning device body 1, the universal wheel 2, and the motor 4 are existing technologies and will not be described in detail; at the same time, the utility model also includes a power supply, a controller, and a switch, which are not the main technical points of this patent and will not be described in detail.

[0032] The implementation steps are divided into two steps: first, the support legs 33 can be adjusted at the same time to facilitate the safety warning device to be supported on the ground; second, the safety warning device can be stably supported on the ground, as follows:

[0033] 1. After the safety warning device body 1 is moved to the specified position by means of the universal wheel 2, the switch is turned on, and the power supply makes the controller work through the wire, and the controller controls the motor 4 to work. The power supply for the safety warning device body 1 can be used as the power supply for energizing the motor 4. In this way, there is no need to connect another power supply, which is convenient for the use of the device. When the safety warning device body 1 has not been supported and stabilized, the cone head 34 is in the supporting leg 33, the pull rope 11 is in a taut state and is wound and accumulated on the first roller 9, and the first spring 35 is in a compressed state. After the motor 4 is powered on, the output end of the motor 4 drives the first connecting rod 5 to rotate, thereby driving the first rollers 9 located at both ends of the first connecting rod 5 to rotate. At the same time, the first connecting rod 5 drives the first gear 7 to rotate, thereby driving the second gear 8 to rotate, thereby driving the second connecting rod 6 to rotate in the opposite direction relative to the first connecting rod 5, that is, the second connecting rod 6 rotates relative to the first connecting rod 5, which can bring The first rollers 9 at both ends of the second connecting rod 6 are driven to rotate, so that the pull rope 11 wound and accumulated on the first roller 9 can be released, so that the first spring 35 in the compressed state can be extended, and then the second connecting plate 32 and the supporting leg 33 can be driven to move downward until the four supporting legs 33 are all in contact with the ground. When the supporting legs 33 are supported on a harder part of the ground, the motor 4 can be turned off. When the surface layer of the ground is relatively soft, the supporting legs 33 will continue to move downward to the harder part of the ground under the action of the first spring 35. When the ground is uneven, the supporting legs 33 in the recessed part of the ground can continue to extend under the action of the first spring 35 until they are in contact with the harder part of the ground for support, so that the safety warning device body 1 can be in a horizontal position without causing tilting. In this way, the supporting legs 33 can be adjusted at the same time, so as to facilitate the effect of supporting the safety warning device body 1 on the ground.

[0034] Second, after the support leg 33 is supported on the ground, a downward force can be applied to the fixing plate 39 using a hammer or other tool to move the cone head 34 downward, so that the cone head 34 can be embedded below the ground supported by the support leg 33, thereby enhancing the support stability of the safety warning device body 1 and making the safety warning device stably supported on the ground. At this time, the second spring 36 changes from the initial state to the extended state;

[0035] When it is necessary to move the safety warning device body 1 after support, the cone head 34 can be pulled up through the fixing plate 39, and under the action of the second spring 36, the cone head 34 will be pulled into the support leg 33, and the inner surface of the cone head 34 and the support leg 33 will abut against each other. When there is dirt and other debris on the cone head 34, the support leg 33 can scrape off the dirt and other debris, and then, the motor 4 is started in reverse. Under the action of the above-mentioned components, the first roller 9 can be rotated in the opposite direction, so that the pull rope 11 is wound and accumulated on the first roller 9, so that the second connecting plate 32 moves upward, thereby moving the support leg 33 upward and retracting it, releasing the support on the ground, until the first spring 35 is compressed to the initial state, and the motor 4 is turned off to stop the first roller 9 from rotating, and then, the safety warning device body 1 is moved through the universal wheel 2.

[0036] Specifically, the support mechanism 3 further includes a first guide plate 37 fixed to the first connecting plate 31 by screws, a second guide plate 38 fixed to the second connecting plate 32 by screws is slidably arranged on the first guide plate 37, and the first spring 35 is located between the two first guide plates 37. In the utility model, the arrangement of the first guide plate 37 and the second guide plate 38 can ensure that the support leg 33 moves in the vertical direction, and at the same time, can reduce the disturbance of the support leg 33 caused by the shaking of the first spring 35 when it is extended or compressed, thereby increasing the stability of the safety warning device body 1;

[0037] The first guide plate 37 is provided with a slider (not shown in the figure), and the second guide plate 38 is provided with a slide groove matching the slider. When the first spring 35 is compressed to the initial state (that is, when the safety warning device body 1 is not supported), the second guide plate 38 slides to fit the surface of the first guide plate 37. At the same time, the first guide plate 37 and the second guide plate 38 are not limited to the two plates sliding on each other. According to the elastic force of the first spring 35, the number of plates that slide on each other can be increased to meet the better use of the device.

[0038] Furthermore, the second support plates 14 located above the support mechanism 3 are symmetrically fixed by screws around the bottom of the safety warning device body 1, and a second roller 12 is rotatably arranged between every two second support plates 14 through a rotating shaft, and the pull rope 11 movably passes through the first connecting plate 31 and the first spring 35 and is placed on the second roller 12. In the present utility model, the arrangement of the second roller 12 can adjust the pull rope 11 fixed in the middle of the second connecting plate 32 and vertically upward to a horizontal direction, and play a role in steering and supporting the pull rope 11, so that the force of the first roller 9 on the pull rope 11 can be converted from a horizontal force to a vertical force on the second connecting plate 32, thereby ensuring that the device can be used more smoothly.

[0039] Furthermore, a support rod 15 located between the first roller 9 and the second roller 12 is symmetrically welded at the bottom of the safety warning device body 1, and a guide ring 13 for guiding the pull rope 11 is welded at the lower end of the support rod 15, and the pull rope 11 passes through the middle of the guide ring 13. In the utility model, the guide ring 13 guides and supports the pull rope 11, and when the ground is uneven, the support leg 33 at the convex part of the ground will contact the ground first, and at this time, the first roller 9 at this position will continue to rotate, and the pull rope 11 will continue to be released from the first roller 9 to loosen, and at this time, the guide ring 13 will support the pull rope 11 and prevent the pull rope 11 from being entangled and knotted. When the support leg 33 is retracted and the first roller 9 is reversed, the guide ring 13 will straighten the pull rope 11 and re-wind it on the first roller 9. At the same time, the guide ring 13 can also prevent the pull rope 11 from slipping off;

[0040] The pull rope 11 can be made of steel wire rope or nylon rope, which can ensure that the pull rope 11 has high strength and tensile properties, ensuring the normal operation and use of the device, including, but not limited to, if there is a better material, it can be used.

[0041] It is worth noting that the first roller 9 and the second roller 12 are both provided with an arc groove for winding the pull rope 11. The upper end of the arc groove of the first roller 9 is flush with the upper end of the arc groove of the second roller 12, and the side end of the arc groove of the second roller 12 is on the same vertical line as the middle of the second connecting plate 32. In the utility model, the setting of the arc groove is used for winding and stacking the pull rope 11, and can also prevent the pull rope 11 from slipping off. The upper ends of the arc grooves of the first roller 9 and the second roller 12 are flush, the pull rope 11 is fixed to the middle of the second connecting plate 32, and the side end of the arc groove of the second roller 12 is flush with the middle of the second connecting plate 32, thereby ensuring that the pull rope 11 can be better transmitted in the horizontal and vertical directions, so that the effect on the support leg 33 is better, so that the device can be better used.

[0042] In the present invention, when the supporting ground is a hard concrete or other road surface, the safety warning device can be supported on the ground through the supporting legs 33 by using the above-mentioned step one, and there is no need to use the cone head 34 in step two, and only the supporting legs 33 are used for support; the first spring 35 adopts a spring with higher strength to ensure that the first spring 35 has higher elastic force and supporting effect.

[0043] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
