Description

Technical Field

[0001] The present invention relates to the technical field of fence-type protection, and particularly to a safety protection device for municipal road and bridge construction. Background Art

[0002] Municipal roads are an important part of urban infrastructure, mainly serving the traffic needs within the city and connecting various functional areas such as residential areas, commercial areas, industrial areas, and public service facilities.

[0003] As a part of the road, a bridge mainly functions to span natural or man-made obstacles, and thus is an important part of the municipal road system. The components of a bridge are the bridge deck, abutment, and pier. However, during the initial construction of the bridge, the related structures of the bridge deck are laid and installed last. Since the outer protective parts are not installed on the bridge body at this time, an outer protective device is required during the construction of the bridge deck to ensure safety during construction.

[0004] However, the existing safety protection devices for municipal road and bridge construction have the following deficiencies: The traditional protection device has poor structural unity, requires a large amount of manual assembly one by one, and the erection conditions are restricted by many factors. The formed protection device mostly uses fixed points for fixation. Therefore, the protection position cannot be changed arbitrarily, which not only makes the device difficult to disassemble and assemble, but also has a high usage limitation.

[0005] The structural strength of the traditional protection device mainly depends on the fixation method and the material itself. Due to the limitation of the installation method, when facing external impacts, it cannot buffer the force, resulting in poor toughness of the structure itself, and is extremely easy to cause deformation and loss, losing the basic protection performance.

[0006] Therefore, we propose a safety protection device for municipal road and bridge construction to solve the problems raised above. Summary of the Invention

[0007] The purpose of the present invention is to provide a safety protection device for municipal road and bridge construction.

[0018] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention realizes the ability of the device to move forward and backward and left and right by setting an adaptive two-way control mechanism and two traveling components. During the process, the first traveling component is used to transfer the device body to the side of the bridge and autonomously complete the docking process with the side of the bridge. Through the reasonable setting of relevant components, finally, some structures can adaptively control the longitudinal span height according to the thickness of the bridge deck and firmly clamp to the side of the bridge in a clamping manner. Then, by utilizing the ability of the second traveling component to move left and right and the cooperative relationship of multiple components, the two main components can be quickly driven to move away from each other without being interfered by the first traveling component, enabling the built-in protective frame to be quickly deployed. The mechanism adopts the principle of mechanical transmission, providing a relatively complete assembly, improving the many drawbacks existing in repeated disassembly and installation, and having a small dependence on the construction conditions, which can reduce the use limitations of the device. The position translation, locking, and component deployment can all be completed autonomously, greatly reducing the manual intervention items, effectively reducing the personnel input, shortening the construction time of the protective equipment, and enabling the bridge deck construction to proceed quickly.

[0019] 2. The present invention sets an image capture component and directly docks it with the device system module, aiming to capture the front image in real time for recording the situation of the bridge deck. Through the analysis of relevant system modules, it is judged whether the erected protective body is within the construction range. If the result is negative, the position of the device remains unchanged; otherwise, under the coordination of the second traveling component mentioned above, the device can follow the construction position, which can increase the intelligence and self-adaptability of the device, thereby ensuring that the device always has the best protective ability.

[0020] 3. The present invention sets a self-acting reverse thrust mechanism, which has a triple boost structure and mainly uses air pressure and reverse elastic force to provide forward reverse thrust. After the device is deployed, if it is impacted by an external object from the front, the generated impact force will force the relevant components to stretch, causing the protective frame to extend outward by a certain distance. Subsequently, a strong reverse thrust effect can be provided to the front of the protective frame, which can protect its own structure while further preventing personnel from falling and further improving the protective ability of the device.

[0026] The effects achieved by the entire Embodiment 1 are as follows: By presetting the above components, there are two traveling components in the mechanism, enabling the device body to move forward and backward and left and right.

Through the reasonable setting of relevant components, the final part of the structure can adaptively control the longitudinal span height according to the thickness of the bridge deck and firmly clamp to the side of the bridge in a clamping manner. In the second stage, by utilizing the ability of the second traveling component to move left and right and the collaborative relationship of multiple components, the two main components can be quickly driven to move away from each other without being interfered by the first traveling component, enabling the built-in protective frame to be quickly deployed.

The input end of each information line 8 is respectively connected to the output end of a corresponding macro camera 6.

[0028] The effect achieved by the entire Example 2 is as follows: By presetting the above components, image capture components are installed in the set main components and directly docked with the device system module, aiming to capture the front image in real time for recording the bridge deck conditions. Through the analysis of relevant system modules, it is judged whether the erected protective body is within the construction range. If the result is negative, the device position remains unchanged. Otherwise, with the coordination of the above second traveling component, the device can follow the construction position. This effect can increase the intelligence and self - adaptability of the device, thus ensuring that the device always has the best protection ability.

[0029] Example 3, according to Figure 1 、 Figure 6 and Figure 7 As shown, the self - actuated counter - thrust mechanism 4 includes two inner trough bodies 401, each inner trough body 401 is respectively opened inside a corresponding main housing cover 1. Inside each inner trough body 401, an alloy plate 402 is fixedly installed. On the front surface of each alloy plate 402, a set of cavities 403 is fixedly installed. Inside the inner wall of each cavity 403, a cylindrical piston 404 is movably arranged. At the end of each cavity 403, a sealing joint 405 is fixedly installed. Inside the inner wall of each sealing joint 405, a metal pull rod 406 is movably inserted. One end of each metal pull rod 406 is respectively fixedly inserted inside a corresponding cylindrical piston 404. Between the outer ends of the outer walls of each group of metal pull rods 406, an induction housing sleeve 408 is fixedly installed. Between the outer wall of each cylindrical piston 404 and the inner wall of a corresponding cavity 403, a first cooperation spring 407 is fixedly installed. Between the opposite sides of the alloy plate 402 and the induction housing sleeve 408, a set of second cooperation springs 409 is fixedly installed. Each group of second cooperation springs 409 is equal to a set of cavities 403, and each second cooperation spring 409 is respectively movably sleeved on the outer surface of a corresponding metal pull rod 406. Between the inner walls of the two induction housing sleeves 408, a folding protective frame 410 is provided.

[0030] The effect achieved by the entire Example 3 is as follows: By presetting the above components, the mechanism is provided with a triple boost structure, mainly using air pressure and reverse elastic force to provide forward counter - thrust. After the device is deployed, if it is impacted by an external object from the front, the generated impact force will force the relevant components to stretch, causing the protective frame to extend outward by a certain distance. The purpose is, on the one hand, to continuously weaken the external force impact on the protective frame body under the treatment of each component, and on the other hand, to quickly separate the protective frame from the impact point to avoid serious damage to some areas of the protective frame. The subsequent counter - thrust generated by each component can act positively on the impact object. For example, when a relevant person collides with the protective frame, the self - generated counter - thrust of the protective frame can push the person away to a safe place. Thus, in this way, while protecting its own structure, it can also further prevent people from falling and further improve the protection ability of the device.

[0031] Example 4, according toFigures 8-10 As shown, after the bridge body is formed, during the bridge deck construction process, the protection positions are mainly concentrated on both sides of the bridge deck to prevent construction workers from falling. The operation of the equipment is divided into three stages. In the first stage, the relevant driving components continuously deliver power to the second auxiliary wheel, driving the equipment to move back and forth until the end component is suspended and freely falls, forcing the upper component to fully contact the bridge deck. Then, the collaborative component reasonably lowers the height of the lower component according to the thickness of the bridge deck. In the second stage, when the upper component and the lower component can longitudinally enter the bridge body, with the cooperation of the first transverse auxiliary wheel and the second transverse auxiliary wheel, they further penetrate into one side of the bridge body, clamping the upper and lower components to one side of the bridge body to minimize the distance between the structure and one side of the bridge body. In the third stage, the height of the lower component is continuously lowered through the collaborative component, causing the second transverse auxiliary wheel to disengage from the bottom of the bridge body, and at the same time lowering the height of the third transverse auxiliary wheel to jack up the main body of the equipment. Subsequently, under the action of the driving component, the two main components move away from each other, quickly unfolding the built-in protection component.

[0032] The working principle of the entire equipment is as follows: Using a specified conveying tool, first transfer the equipment to the bridge deck under construction, check the equipment status, and ensure that the energy in the two lithium battery boxes 15 is sufficient. The purpose is to continuously deliver the energy to the main component through the wire 16 to provide energy for each electrical component.

[0033] In the positioning stage, each first driving component 316 is synchronously activated. Utilizing the movable connection between the first lower support plate 312 and the second cross bar 313, and the collaborative work of the first traction component 315, the power is directly applied to the second transverse auxiliary wheel 314, driving the main housing 1 and its connected components to slowly move towards one side of the bridge deck until the second transverse auxiliary wheel 314 is completely disengaged from the bridge deck. At this time, under the action of gravity, the main housing 1 can quickly fall downward. Since the second transverse auxiliary wheel 314 is arranged at the end of the main housing 1, during the falling process, the actual gravity of the main housing 1 is still on the bridge deck, and by extending the width of the extended extension plate 2, it is ensured that the main housing 1 does not roll over backward. The electric telescopic component 307 is activated, and its inner shaft extends outward. Utilizing the movable connection between the sliding sleeve 302 and the T-shaped sliding table 303, and the inner opening limiting groove 304 and the linkage clamping seat 305, the first associated frame 308 and its connected components are driven to slowly move downward until one of the second transverse auxiliary wheels 314 can fully contact the bottom of the bridge deck. The first driving component 316 is activated again, and by utilizing the movable connection between the first cross bar 310 and the first transverse auxiliary wheel 311, the first associated frame 308 is slowly driven to deeply insert into the side of the bridge body to minimize the distance between the first associated frame 308 and the side of the bridge body. During the unfolding stage, the electric telescopic component 307 further lowers the height of the second lateral auxiliary wheel 314 to disengage it from the bottom of the bridge deck, and the hydraulic component 319 is activated to extend its inner shaft outward, driving the cooperation frame 321 and its connected components to continuously lower their heights. When the third lateral auxiliary wheel 328 contacts the bridge deck and continues with the downward pressure trend, the main housing cover 1 will be slowly lifted, ensuring that neither the first lateral auxiliary wheel 311 nor the second lateral auxiliary wheel 314 contacts the bridge body. At the same time, two second drive components 326 are activated to rotate in opposite directions. With the cooperation of the second traction component 325 and the third traction component 327, power is directly applied to each group of third lateral auxiliary wheels 328, driving the two main housing covers 1 to move away from each other until the folding protection frames 410 in the two induction housing sleeves 408 are fully unfolded. During this process, the macro camera 6 captures the image directly in front of the device in real time, and the range is determined by the wide angle of the macro camera 6. The obtained data can be shared with the relevant system modules in real time and analyzed to make a judgment, controlling the second drive component 326 to complete position following and setting the protection position within the optimal range. Subsequently, the pneumatic component 12 is activated to quickly extend its inner shaft outward and act on the second connection frame 13, driving the alloy cone head 14 to be slightly inserted into the bridge deck to complete the final fixation of the main component.

[0034] During the counter - push stage, when an external object or person impacts the front of the folding protection frame 410, using the movable connection of the sealing joint 405 and the metal pull rod 406, and under the reaction of the first cooperation spring 407, the second cooperation spring 409, and the compressed gas, the folding protection frame 410 shows an intermittent backward movement state to continuously remove the external force. When the folding protection frame 410 moves backward to the maximum range, both the first cooperation spring 407 and the second cooperation spring 409 are in a stretched state. Then, the reaction forces generated by the two and the reverse effect generated by the columnar piston 404 compressing air jointly assist the folding protection frame 410 to reset.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
