Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In a first aspect of the present invention, as shown in fig. 1, the lane closing mechanism includes a warning device 1, an expansion plate 21, and an expansion driving mechanism for driving the expansion plate 21 to expand and retract, a support plate 22 capable of being overlapped on the expansion plate 21 is disposed on the expansion plate 21, one end of the support plate 22 is rotatably connected to the expansion plate 21, and the warning device 1 is disposed at the other end of the support plate 22; and a limiting plate 23 for limiting the vertical movement and the horizontal unfolding angle of the support plate 22 is further arranged at the joint of the support plate 22 and the unfolding plate 21.
Wherein a lane closure of this embodiment is typically located at the side of a highway, it will be appreciated that the deployable panel is located proximate to the ground in order to avoid damage from vehicle impact. One end of the unfolding plate is connected with the unfolding driving mechanism, the other end of the unfolding plate is a free end, and the free end of the unfolding plate is normally in a retracting state. The warning device can be a warning post, a cone mark, a warning board and the like; the warning device can be made of light materials, such as foam plastics, and can still keep a vertical posture after being impacted under the action of the limiting block. The limiting plate and the unfolding plate can clamp the support plate, and the maximum unfolding angle of the support plate in the horizontal direction can be limited by the shape of the groove on the inner side of the limiting plate; in the embodiment, the support plate which is knocked open can automatically return to the position which is initially overlapped with the expansion plate when being retracted, and only an object is required to limit the warning device at the retracted position, so that the original curbs, guardrails or baffles at the roadside of the road can be utilized; in order to make the supporting plate return to the correct position above the sliding plate more easily when the unfolding plate is retracted, the limiting plate limits the maximum unfolding angle of the supporting plate to be not more than 90 degrees, and preferably can be set to be about 70-80 degrees.
When the lane closing mechanism of the embodiment operates, the unfolding driving mechanism drives the unfolding plate to be slowly unfolded to a certain angle from the retracted state parallel to the road and then to stop, when the unfolding plate is unfolded, the static friction force between the supporting plate and the unfolding plate enables the supporting plate not to move relative to the unfolding plate, and the warning device is positioned at the free end of the unfolding plate; when a vehicle passes through, if the vehicle touches the warning device, the warning device can be knocked away by the vehicle and deviates from the expansion plate by a certain angle because the support plate where the warning device is located can horizontally rotate on the expansion plate, so that the road closing mechanism can be prevented from being damaged. The limiting plate limits the unfolding angle of the support plate to a certain degree, usually, the limiting plate can be an acute angle, so that the alarm device cannot rotate by an excessively large angle to the extent that the alarm device cannot correctly return to the free end of the unfolding plate when being retracted, and the next work cannot be influenced.
The device structure for sealing the lane in the prior art has poor anti-collision effect and short service life. The embodiment arranges the support plate which can limit and rotate in the horizontal direction on the expansion plate and arranges the warning device on the support plate, so that the impact force caused by vehicle impact can be well buffered, the device is effectively prevented from being damaged due to impact, and the service life of the device is obviously prolonged.
In one embodiment, as shown in fig. 1, the deployment driving mechanism includes a first driving motor and a reduction transmission mechanism connected to an output end of the first driving motor, and an output shaft 29 of the reduction transmission mechanism is connected to the deployment plate 21. Preferably, the reduction transmission mechanism may include a gear reducer 27, an output shaft 29 of the gear reducer 27 is provided with the angle sensor 3, and the output shaft 29 of the gear reducer 27 is further connected to the deployment plate 21.
The speed reduction transmission mechanism can adopt a gear reducer and also can adopt a scheme of linear driving matched with gear reduction. As shown in fig. 1, the gear reducer may include an input shaft and an output shaft mounted on a bracket, the input shaft being provided with an input gear 28 and a coaxial gear, the coaxial gear being engaged with a driven gear on an output shaft 29; the end of the electric push rod 24 is connected to a rack 26 mounted on the guide rail 25, said rack 26 being engaged with an input gear 28 of a gear reducer 27. The electric push rod (comprising a first driving motor) provides linear driving, and the linear driving is output as the rotation of the expansion plate through the reduction gear by converting the displacement of the rack into the rotation of the gear. Thus, the unfolding plate can be unfolded stably and slowly, and drivers who pass by the road can be prevented from being scared by too high unfolding speed.
In one embodiment, as shown in fig. 1-2, the deployment plate 21 includes a sliding slot 211 having a limiting portion 2111, and a sliding plate 212 capable of sliding in the sliding slot 211, one end of the sliding slot 211 is connected to the output shaft 29 of the reduction transmission mechanism, and one end of the support plate 22 is rotatably connected to the middle of the sliding plate 212; and a telescopic driving mechanism 4 for controlling the telescopic movement of the sliding plate 212.
The limiting part is an inward bending part which is arranged on the sliding chute and used for limiting the sliding of the sliding plate in the sliding chute. The aforementioned solution is more suitable for the case of closing a single lane, while sometimes it is necessary to close a double lane. In the prior art, the sealing of a single lane and the sealing of a double lane are performed by different devices, and the sealing of the single lane and the sealing of the double lane cannot be realized at the same time. In order to realize the function of flexibly switching and sealing single and double lanes on a lane sealing device, the applicant divides an expansion plate into a sliding chute and a sliding plate and adds a telescopic driving mechanism.
As an optimized embodiment, as shown in fig. 1, the telescopic driving mechanism 4 includes a second driving motor 41, a screw rod 42 connected to an output end of the second driving motor 41, a winding reel 43 disposed on the screw rod 42 and in threaded connection with the screw rod 42, and a wire rope; the two ends of the steel wire rope are respectively wound on the winding reel 43 and fixed on the two sides of the winding reel 43, the steel wire rope penetrates between the sliding chute 211 and the sliding plate 212 and bypasses the winding post 2113 arranged at the position close to the free end of the sliding chute, and the steel wire rope and the sliding plate 212 are fixed on one side, far away from the warning device, of the sliding plate 212.
The second driving motor can be connected with the screw rod through a coupler. The free end of the sliding groove is the end of the sliding groove far away from the output shaft of the speed reduction transmission mechanism. The two ends of the steel wire rope are wound on the winding reel and fixed, the steel wire rope bypasses the winding posts at the free ends of the sliding grooves and is fixed with one side of the sliding plate far away from the warning device, the fixed point of the steel wire rope on the sliding plate can be moved by controlling the rotating direction of the second driving motor, and then the sliding plate can be moved in the sliding grooves.
When the winding reel operates, the winding reel rotates and moves axially along one side under the driving of the second driving motor and the screw rod; the steel wire rope is wound at one end of the winding reel and is paid out at the other end of the winding reel, and the steel wire rope is always wound in one direction without being repeatedly wound in one place or being disorderly due to the axial movement. The other side of the steel wire rope fixedly connected with the sliding plate is also driven to move, so that the sliding plate can extend out or retract in the sliding groove through the telescopic driving mechanism.
In one embodiment, as shown in fig. 1-2, the retaining portion 2111 is disposed near the free end of the sliding slot 211.
The applicant has found that if the chute is made in a conventional manner, i.e. the limiting parts are arranged in the length direction of the whole chute, the following problems are encountered: when the vehicle passes through the deployment floor, if the slide board is already extended, the vehicle is likely to run over the slide groove stopper portion without the support of the slide board, which easily damages the structure of the stopper portion so that the extended slide board cannot be retracted. Considering that the slide plate can not extend out of the slide groove completely, a part of the slide groove is always positioned in the slide groove, and the part of the slide groove limiting part can not be damaged even if the slide groove limiting part is rolled over the structure of the slide groove due to the support of the slide plate, so that the applicant cancels the limiting part of the slide groove in most places in the conventional design and only keeps a part of the slide groove limiting part at a position close to the free end of the slide groove so as to prevent the slide plate from being separated from the slide groove.
In one embodiment, as shown in fig. 1-2, the sliding slot 211 has two sides with inclined surfaces 2112 inclined outward, and the top surface of the sliding plate 212 is slightly higher than the height of the limiting portion 2111 of the sliding slot 211.
Wherein, if the both sides of slide are conventional straight face, the height of slide is flushed with the spout or is lower, then can cause the impact to the spout when the vehicle passes by, influences stable in structure. In the embodiment, the inclined plane is arranged on the sliding chute and the height of the top surface of the sliding plate is raised, so that when a vehicle passes by, the wheel firstly contacts the inclined plane on one side of the sliding chute, then comes to the top surface of the sliding plate and finally leaves from the inclined plane on the other side of the sliding chute. Therefore, on one hand, the wheels can be prevented from directly applying pressure to the limiting parts, on the other hand, the impact force of the inclined planes of the sliding grooves can be reduced, the abrasion of the expansion plates is effectively reduced, and the service life is prolonged. The scheme of the embodiment is combined with the previous embodiment, so that the effect is better.
In a second aspect of the present invention, a lane closing apparatus, as shown in fig. 3, includes the aforementioned lane closing mechanism having the first drive motor, and further includes:
the angle sensor 3 is used for acquiring the rotation angle of an output shaft of the speed reduction transmission mechanism and sending the rotation angle to the control device;

Wherein, the control device can adopt MCU. The instructions may include an unfolding instruction, a stopping instruction, a retracting instruction and the like, wherein the unfolding and retracting instruction is used for starting the first driving motor to operate, and the stopping instruction is used for stopping the first driving motor to operate. The deployment instruction includes a target rotation angle value.
When the road closing device runs, if the wireless communication module receives an instruction, the wireless communication module sends the instruction to the control device, and the control device controls the first driving motor to run according to the instruction. If the control device detects that the rotation angle reaches the target value through the angle sensor when the control device operates the unfolding/folding instruction, the first driving motor stops operating, feedback information is generated, and the feedback information is sent to the cloud server through the wireless communication module. If the control device detects that the current value reaches the threshold value through the current acquisition device when the control device operates the unfolding/folding instruction, the unfolding plate is judged to be blocked, the first driving motor is stopped to operate, feedback information of the blocking is generated, and the feedback information is sent to the cloud server through the wireless communication module. Thus, the remote control of the site lane closing mechanism can be realized.
Preferably, as shown in fig. 3, the lane closing device includes the lane closing mechanism having the first and second drive motors, and further includes:
the angle sensor 3 is used for acquiring the rotation angle of an output shaft of the speed reduction transmission mechanism and sending the rotation angle to the control device;
