Technical Field
[0001] This utility model relates to the technical field of anti-collision warning devices, specifically a bridge anti-collision warning device. Background Technology
[0002] In the process of protecting highway bridges, anti-collision warning devices are required. Patent publication number CN220704373U discloses a highway bridge anti-collision warning device, including a movable base. A sleeve column is provided on the top of the movable base, and a lifting column is movably installed inside the sleeve column. Limiting holes are provided on the corresponding surfaces of the lifting column and the sleeve column. A limiting post is inserted into the inner side of each limiting hole. A fixing frame is provided on the top of the lifting column, and adjusting plates are provided on both sides of the fixing frame. Adjusting holes are provided on the surfaces of the adjusting plates, and adjusting studs are provided inside each adjusting hole. A clamping plate is provided at the opposite end of each adjusting stud. This highway bridge anti-collision warning device allows for manual extension and retraction of the lifting column inside the sleeve column according to actual installation needs. The lifting column is fixed by inserting the limiting post into the limiting hole, thus adjusting the overall height of the warning sign. This replaces the traditional fixed structure installation, avoiding limited flexibility in use.
[0003] The existing technical solutions described above have the following drawbacks: In the design of the lifting structure of mechanical equipment, the use of limit holes and limit columns in combination can provide stable support and precise positioning for the lifting column, ensuring its stable operation and accurate adjustment in the vertical direction. However, the limit holes and limit columns are completely exposed to the external environment without any protective measures. As the equipment operates for longer periods, dust, gravel, fibers, and other impurities in the environment will continuously penetrate into the limit holes, gradually accumulating and forming blockages. At the same time, the contact parts of the limit holes and limit columns are subject to long-term exposure to environmental factors such as humidity and oxidation, making them highly susceptible to corrosion. These problems not only cause the lifting column to jam and increase resistance during adjustment, but also significantly reduce its adjustment efficiency, affecting the overall operating performance and service life of the equipment, and may even lead to safety hazards due to component jamming. Utility Model Content
[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide a bridge anti-collision warning device, which has the advantage of stable adjustment. It solves the problem that when the limiting hole and the limiting post are completely exposed to the external environment without any protective measures, as the equipment operates for a longer period of time, impurities such as dust, gravel, and fibers in the environment will continuously invade the limiting hole, gradually accumulate and form a blockage. At the same time, the contact moving parts of the limiting hole and the limiting post are easily corroded due to long-term exposure to environmental factors such as moisture and oxidation.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a bridge anti-collision warning device, including a vertical plate frame, with sliding grooves on both sides of the vertical plate frame, a sliding sleeve slidably connected to the surface of the vertical plate frame, a warning sign fixedly connected to the front side of the sliding sleeve, the surface of the sliding sleeve contacting the inner wall of the sliding groove, a slot group being provided on the right side of the inner wall of the sliding groove, a pin being provided inside the slot group, the right side of the pin penetrating into the inner cavity of the sliding sleeve, a moving strip being fixedly connected to the right side of the pin, springs being fixedly connected to the front and rear sides of the right side of the moving strip, an installation block being fixedly connected to the right side of the spring, the surface of the installation block being fixedly connected to the inner wall of the sliding sleeve, and a control mechanism being movably connected to the right side of the moving strip.
[0006] In a preferred embodiment of this utility model, the control mechanism includes a transmission plate, which is movably connected to the right side of the moving bar. A rocker plate is movably connected to the right side of the transmission plate, and the rocker plate is movably connected to the inner cavity of the sliding sleeve. A push plate is fixedly connected to the right side of the rocker plate, and a push rod is fixedly connected to the right side of the push plate. The right side of the push rod extends through to the right side of the sliding sleeve.
[0007] As a preferred embodiment of this invention, a circular plate is fixedly connected to the right side of the push rod, and the circular plate is located inside the sliding sleeve.
[0008] As a preferred embodiment of this invention, a stabilizing sleeve is fitted onto the surface of the push rod, and the surface of the stabilizing sleeve is fixedly connected to the right side of the sliding sleeve.
[0009] As a preferred embodiment of this invention, a pulley is rotatably connected to the right side of the rocker, and the surface of the pulley is in contact with the surface of the pusher plate.
[0010] As a preferred embodiment of this invention, a torsion spring is fixedly connected to the bottom of the rocker, and the bottom of the torsion spring is fixedly connected to the bottom of the inner wall of the sliding sleeve.
[0011] As a preferred embodiment of this invention, a sliding rod is fixedly connected to the left side of the mounting block, and the sliding rod is located inside the moving bar.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model involves pushing a push rod to the left, which in turn moves a push plate to the left. The push plate then rotates a rocker, which in turn pulls a transmission plate to the right. The transmission plate then moves a moving bar and a pin to the right. The moving bar compresses a spring, causing the pin to disengage from the slot assembly. The sliding sleeve then loses its fixation, allowing the warning sign to slide on the surface of the vertical frame. After adjusting the warning sign to the appropriate position, the push rod can be released, allowing the pin to re-engage with the slot assembly to position the sliding sleeve and the warning sign. This design offers the advantage of stable adjustment. The locking assembly is located in a closed space, preventing dust, sand, fibers, and other environmental contaminants from contacting the locking assembly, thus improving the stability of the warning sign.
[0014] 2. By setting up a control mechanism, this utility model can control the pin, avoiding the pin being unable to move and thus unable to separate and cooperate with the card slot assembly, thereby improving the adjustment effect of the warning sign.
[0015] 3. By setting a circular plate, this utility model can increase the contact area between the user and the push rod, avoiding a small contact area between the push rod and the user, and improving the pushing efficiency of the push rod. Attached Figure Description

Detailed Implementation
[0021] 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.
[0022] like Figures 1 to 4As shown, the bridge anti-collision warning device provided by this utility model includes a vertical plate frame 1. Slide grooves 2 are provided on both sides of the vertical plate frame 1. A sliding sleeve 3 is slidably connected to the surface of the vertical plate frame 1. A warning sign 4 is fixedly connected to the front side of the sliding sleeve 3. The surface of the sliding sleeve 3 contacts the inner wall of the slide groove 2. A slot group 5 is provided on the right side of the inner wall of the slide groove 2. A pin 6 is provided inside the slot group 5. The right side of the pin 6 extends through to the inner cavity of the sliding sleeve 3. A moving strip 7 is fixedly connected to the right side of the pin 6. Springs 8 are fixedly connected to the front and rear sides of the right side of the moving strip 7. An installation block 9 is fixedly connected to the right side of the spring 8. The surface of the installation block 9 is fixedly connected to the inner wall of the sliding sleeve 3. A control mechanism 10 is movably connected to the right side of the moving strip 7.
[0023] refer to Figure 4 The control mechanism 10 includes a transmission plate 101, which is movably connected to the right side of the moving bar 7. A rocker plate 102 is movably connected to the right side of the transmission plate 101. The rocker plate 102 is movably connected to the inner cavity of the sliding sleeve 3. A push plate 103 is fixedly connected to the right side of the rocker plate 102. A push rod 104 is fixedly connected to the right side of the push plate 103. The right side of the push rod 104 extends through to the right side of the sliding sleeve 3.
[0024] As a technical optimization of this utility model, by setting up a control mechanism 10, the pin 6 can be controlled, avoiding the pin 6 from being unable to move, which would prevent it from separating and engaging with the card slot group 5, thus improving the adjustment effect of the warning sign 4.
[0025] refer to Figure 4 A circular plate 11 is fixedly connected to the right side of the push rod 104, and the circular plate 11 is located inside the sliding sleeve 3.
[0026] As a technical optimization of this utility model, by setting the circular plate 11, the contact area between the user and the push rod 104 can be increased, avoiding the small contact area between the push rod 104 and the user, and improving the pushing efficiency of the push rod 104.
[0027] refer to Figure 4 A stabilizing sleeve 12 is fitted onto the surface of the push rod 104, and the surface of the stabilizing sleeve 12 is fixedly connected to the right side of the sliding sleeve 3.
[0028] As a technical optimization of this utility model, by setting the stabilizing sleeve 12, the push rod 104 can slide stably, avoiding the push rod 104 from shaking during the sliding movement, which would cause the push rod 104 to loosen, thus improving the sliding stability of the push rod 104.
[0029] refer to Figure 4 A pulley 13 is rotatably connected to the right side of the rocker 102, and the surface of the pulley 13 is in contact with the surface of the push plate 103.
[0030] As a technical optimization of this utility model, by setting the pulley 13, the rocker 102 can be isolated from the push plate 103, avoiding friction between the push plate 103 and the surface of the rocker 102 when the push plate 103 moves, which would cause the surface of the rocker 102 to be worn, thus improving the installation safety of the rocker 102.
[0031] refer to Figure 4 A torsion spring 14 is fixedly connected to the bottom of the rocker 102, and the bottom of the torsion spring 14 is fixedly connected to the bottom of the inner wall of the sliding sleeve 3.
[0032] As a technical optimization of this utility model, by setting a torsion spring 14, the rocker 102 can be pulled to automatically reset and move, avoiding the rocker 102 from failing to automatically return to its original position after being pushed, requiring manual reset, thus improving the ease of use of the rocker 102.
[0033] refer to Figure 4 A slide bar 15 is fixedly connected to the left side of the mounting block 9, and the slide bar 15 is located inside the moving bar 7.
[0034] As a technical optimization of this utility model, by setting the slide bar 15, the moving bar 7 can slide stably, avoiding the shaking of the moving bar 7 during the sliding process, which would cause the moving bar 7 to loosen, thus improving the sliding stability of the moving bar 7.
[0035] The working principle and usage process of this utility model are as follows: When it is necessary to adjust the position of the warning sign 4, push the push rod 104 to move to the left. The push rod 104 drives the push plate 103 to move to the left. The push plate 103 drives the rocker 102 to rotate. The rocker 102 drives the transmission plate 101 to pull to the right. The transmission plate 101 drives the moving bar 7 and the pin 6 to move to the right. The moving bar 7 compresses the spring 8. The pin 6 exits the inside of the slot group 5. The sliding sleeve 3 loses its fixation. The sliding sleeve 3 can then drive the warning sign 4 to slide on the surface of the vertical plate frame 1. After adjusting the warning sign 4 to the appropriate position, the push rod 104 can be released so that the pin 6 can re-engage with the slot group 5 to position the sliding sleeve 3 and the warning sign 4.
[0036] In summary, this bridge anti-collision warning device, through the coordinated use of the vertical plate frame 1, sliding groove 2, sliding sleeve 3, warning sign 4, card slot group 5, pin 6, moving strip 7, spring 8, mounting block 9, and control mechanism 10, solves the problem that when the limiting hole and limiting post are completely exposed to the external environment without any protective measures, as the equipment operates for a longer period of time, dust, gravel, fibers, and other impurities in the environment will continuously invade the limiting hole, gradually accumulate, and form a blockage. At the same time, the contact moving parts of the limiting hole and limiting post are easily corroded due to long-term exposure to environmental factors such as moisture and oxidation.
