It will be appreciated by those skilled in the art that the following examples illustrate only some, but not all, of the specific embodiments of the invention and that the scope of the invention is not limited thereto.
Referring to fig. 1, this embodiment discloses a safety warning device for road traffic safety facility construction, which comprises a warning sign 1 and a mounting bracket as common warning equipment from the main structure, wherein the warning sign 1 is mounted on the mounting bracket, and in particular to the invention, the mounting bracket comprises a main body 2, a threaded disc 3 is mounted in the main body 2, the threaded disc 3 can be mounted in a self-rotation manner around the center of the main body 2, a planar thread is provided on the upper surface of the threaded disc 3, a plurality of moving columns 6 are in threaded engagement on the planar thread, each moving column 6 is arranged along the radial direction of the threaded disc 3, and all the moving columns 6 are arranged in a circular array on the threaded disc 3, so that all the moving columns 6 move synchronously in the radial direction of the threaded disc 3 when the threaded disc 3 rotates, namely all the moving columns 6 are radially arranged on the surface of the threaded disc 3 and synchronously move.
The movable column 6 is horizontally arranged on the thread disc 3, one end of the movable column can be moved out of the main body 2 so as to be hinged with a connecting shaft 9, the warning board 1 is fixedly connected to the connecting shaft 9, and the warning board 1 is arranged at a certain included angle with the connecting shaft. The upper part of the side surface of the main body 2 is fixedly connected with a rigid limiting rod 7 which is vertically arranged, the lower part of the main body is fixedly connected with an elastic telescopic rod 8 which is horizontally arranged, and the connecting shaft 9 is positioned between the free end of the limiting rod 7 and the free end of the telescopic rod 8 and always keeps extrusion contact with the two free ends in the moving process of the moving column 6. Therefore, when the movable column 6 is used, as long as the threaded disc 3 rotates, all the movable columns 6 are driven to synchronously linearly move towards the directions where the movable columns are located, when the movable columns 6 move towards the outer sides, the connecting columns rotate downwards under the extrusion limiting effect of the end parts of the limiting rods 7, and when the movable columns 6 move towards the central side of the threaded disc 3, the connecting columns rotate upwards, so that the pitching angles of the warning boards 1 are flexibly and synchronously adjusted, the inclination angles of the warning boards 1 can be better selected according to the field environment to better play a warning role when the road is constructed, and the installation height of the movable column is provided with greater selection flexibility, so that the visible range of the movable column can not be adjusted through the height because the inclination positions of the warning boards 1 are fixed. On the other hand, the warning board 1 surrounds the periphery of the main body 2 in a circumferential direction, so that the warning board 1 can be seen in all directions around, and the warning board can not be seen only by head-on observation like the conventional warning board 1.
As a specific implementation structure, the driving mechanism of the screw disc 3 of the present invention is as follows: referring to fig. 1, a vertically arranged mandrel 10 is fixedly connected to the center of the main body 2, a driven fluted disc 11 is fixedly connected to the top end of the mandrel 10, the driven fluted disc 11 is meshed with a driving gear 12 for transmission, referring to fig. 2, an input housing 14 is fixedly connected to a gear shaft of the driving gear 12, a first magnet 18 is installed inside the input housing 14, and an annular chute is formed on the inner wall of the input end of the locking cover 23, and in specific manufacturing, the part of the chute can be in a detachable structure with the rest of the locking cover 23, for example, the part of the chute is separately made into a section and is connected with the rest of the locking cover 23 through bolts, which are specific manufacturing structures which can be easily realized by those skilled in the art. Meanwhile, the embodiment further comprises an output housing 15 fixedly connected with the main shaft of the motor 16, a second magnet 19 mutually exclusive to the first magnet 18 is installed inside the output housing 15, an annular protruding block 21 is arranged at the output end of the output housing 15, the protruding block 21 is installed in the sliding groove in a rotating fit mode, and the repulsive interaction between the first magnet 18 and the second magnet 19 enables the protruding block 21 to be tightly attached to the side wall of the sliding groove, and the input housing 14 and the output housing 15 are integrally connected. In the above design structure, firstly, the motor 16 is started as an output power component to drive the output housing 15 to rotate, that is, torque is transmitted to the input housing 14 through the output housing 15, as shown in fig. 2, the two magnets of the two housings are in a repulsive state, so that the two housings keep a trend of being separated from each other, and the integral connection between the output housing 15 and the input housing 14 is realized by combining the non-separable limiting function between the protruding block 21 and the sliding groove. When the motor 16 rotates, the input housing 14 rotates synchronously, so that the gear shaft is driven to rotate, that is, the driving gear 12 rotates, so that the mandrel 10 is driven to rotate, that is, the threaded disc 3 rotates, and when all the moving posts 6 synchronously move towards the outside of the threaded disc 3 during the movement of the moving posts 6 outwards, the connecting shaft 9 hinged with the moving posts 6 can only rotate downwards due to the limiting effect of the free ends of the limiting rods 7, and therefore, the installation angle of the whole warning sign 1 can be adjusted downwards. On the contrary, when the screw thread disc 3 reversely rotates, all the movable columns 6 move towards one side of the center of the screw thread disc 3, the connecting shaft 9 is driven to move towards one side close to the screw thread disc 3, and at the moment, the connecting columns rotate upwards due to the pushing action of the telescopic rod 8, so that the warning sign 1 is upwards bent for a certain angle.
The safety warning device for road traffic safety facility construction can realize the warning effect around a construction site, can be seen in all directions, can enable people around the site to see warning marks more clearly by matching with the pitching adjusting function of the warning board 1, and can ensure that the moving amount of the moving column 6 is tiny when the threaded disc 3 is in threaded connection with the moving column 6 for adjustment, so that finer adjustment of the pitching angle of the warning board 1 can be realized. On the other hand, the invention has overload prevention function compared with the traditional mechanical direct connection transmission because the connection transmission of the input shell 14 and the output shell 15 is ensured by adopting the repulsive action of two magnets repulsive to each other; that is, in the process of the screw disc 3 and the moving post 6, and the corresponding gear transmission, if an unexpected jamming condition occurs, the input housing 14 and the corresponding gear connected with the input housing are not forced to rotate due to the output torque of the motor 16, that is, once jamming occurs, the repulsive force of the two magnets causes the friction force generated between the protruding block 21 and the inner side wall of the chute to be insufficient to resist the output torque of the motor 16, so that the two housings can relatively slip, thereby playing an overload protection role.
As one of implementation details, as shown in fig. 4-6, a pair of notches 22 are formed on the end surface of the locking cover 23, the notches 22 are communicated with the chute, and two insertion holes 32 are respectively formed on two opposite inner side walls of the chute; the protruding block 21 is not in a ring-shaped structure, but is in a rectangular steel bar-shaped structure, the free end of the protruding block 21 is provided with a sliding pin 34 in a sliding manner through a spring, one end of the sliding pin 34 is installed in the protruding block 21 in a sliding manner, the other end of the sliding pin extends out of the protruding block 21, so that after the protruding block 21 slides downwards into the sliding groove from the notch 22, the two spherical surfaces of the sliding pins 34 extend into the two insertion holes 32 after rotating for a certain angle, and therefore reliable connection between the output shell 15 and the input shell 14 is achieved, and transmission is stable and reliable. Based on the above structure, one specific implementation structure is as follows: the end surface of one end of the sliding pin 34 extending out of the protruding block 21 is a sphere, the port of the inner side end of the insertion hole 32 facing the sliding groove is provided with a rounding angle, after the spherical end of the sliding pin 34 is inserted into the insertion hole 32, when the output housing 15 rotates under the set torsion, the spherical end of the sliding pin 34 can completely slide out of the insertion hole 32, and further the sliding function is realized together with the magnetic repulsive force. And another specific implementation structure is as follows: at least two thirds of the sliding pin 34 is inserted into the jack 32 to better realize the connection transmission of the two shells, and a thimble is connected near the port of one end of the jack 32 away from the chute, and when the thimble is inserted into the jack 32, the sliding pin 34 can be completely pressed back into the protruding block 21, and the angle is slightly rotated, so that the sliding pin 34 temporarily stays at a position which is not matched with the jack 32, and the connection relation between the two shells can be released, and the two shells can recover to realize the overload slipping function by taking account of the repulsive force of the two magnets.
