Description

Technical Field

[0001] This invention relates to the field of bridge construction protection technology, and more specifically, to a bridge repair and reinforcement construction protection system and its process. Background Technology

[0002] Bridge maintenance refers to the collective measures taken to ensure the normal use of bridges, including repair, emergency repair, reinforcement, and protection. This includes continuous technical inspection, repair, and maintenance of bridges; technical measures to locally reinforce bridges to improve their load-bearing and traffic capacity; rapid repair of damaged bridges; and regular camouflage, flood prevention, ice floe protection, protection against explosive drifting objects, and protection against enemy sabotage.

[0003] Chinese invention disclosure CN202110301708.0 discloses a bridge maintenance platform with safety protection function, including a base; a lifting mechanism rotatably connected to the inside of the base; a movable protective component, the bottom of which is fixedly connected to the top of the lifting mechanism, the movable protective component including a top plate, the bottom of which is fixedly connected to the top of the lifting component, and fixed plates fixedly connected to both sides of the top of the top plate; a spare protective spring, the bottom of which is fixedly connected to the top of the base; and a ladder, the back of which is fixedly connected to the front of the base. This bridge maintenance platform with safety protection function can effectively protect maintenance personnel when they climb onto the bridge maintenance platform for maintenance, and can move left and right automatically based on observation of the location requiring maintenance, solving the problem that bridge maintenance platforms cannot protect maintenance personnel during maintenance and can not automatically control left and right movement.

[0004] However, when repairing and changing the location of bridge piers and bridge joints, workers cannot adjust their positions according to their needs while working at height. They still need to control and adjust the position of the inspection platform. Moreover, each time the inspection position is changed, the corresponding protective scaffolding needs to be erected again, which is very troublesome and reduces work efficiency. Therefore, this invention proposes a bridge repair and reinforcement construction protection system to solve the above problems. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the embodiments of the present invention provide a bridge maintenance and reinforcement construction protection system and process, which solves the problems mentioned in the background art by setting an adjustable first support rod and support plate at the bottom of the maintenance platform, so that it is stably supported on the outer wall of the bridge pier and the bottom of the maintenance platform is enclosed for receiving.

The annular enclosure frame is slidably installed on the outer wall of the two limiting slide rods.

[0014] In a preferred embodiment, two inclined limiting chains are fixedly installed at the bottom of the balance block. The limiting chains are fixedly installed on the outer wall of the annular enclosure frame and the outer wall of the rubber enclosure frame.

[0015] In a preferred embodiment, a first support frame is fixedly installed on the outer wall of the annular enclosure frame, a second support frame is fixedly installed on the outer wall of the first support frame, and the second support frame is fixedly installed on the outer wall of the wear-resistant sliding sleeve.

[0016] In a preferred embodiment, the displacement mechanism includes a first base disposed at the bottom of a support platform, a caster wheel fixedly mounted on the top of the first base, a first threaded rod rotatably mounted on one side of the first base in a horizontal arrangement, a plurality of first supporting slide rods fixedly mounted on the bottom of the support platform, threaded blocks fixedly mounted on the outer walls of the plurality of first supporting slide rods, the threaded blocks engaging with the outer walls of the first threaded rods, and a plurality of second sliding grooves opened on the top of the first base, the plurality of first supporting slide rods slidably mounted in the inner cavities of the corresponding second sliding grooves, a third sliding groove opened on the top of the first base, a second supporting slide rod slidably mounted on the top of the third sliding groove, and the second supporting slide rods fixedly mounted at the vertical centerline position of the support platform.

[0017] In a preferred embodiment, the number of the first threaded rods is at least two, and both first threaded rods are rotatably mounted inside the first base and extend out of the outer wall of the first base. One end of the first threaded rod extending out of the outer wall of the first base is fixedly connected to a DC motor for driving its rotation, and gears are fixedly mounted on the outer wall of one side of the first threaded rods extending out of the first base. The outer walls of the two gears are meshed with synchronous belts.

[0018] In a preferred embodiment, the auxiliary limiting mechanism includes a second base fixedly installed on one side of the first base, a waterproof shell fixedly installed on one side of the second base, a rotating shaft rotatably installed between the waterproof shell and the first base, a first support frame fixedly installed on the outer wall of the rotating shaft, a second support frame fixedly installed on the top of the first support frame, and a positioning bolt fixedly installed on the bottom of the first support frame.

[0019] A bevel gear is fixedly connected to one end of the rotating shaft that penetrates through the waterproof shell and extends into the interior of the waterproof shell. A turbine rod meshes with the outer wall of the bevel gear. A support block is fixedly installed on the inner wall of the waterproof shell. The turbine rod is rotatably installed inside the support block. A second threaded rod is rotatably installed on the top of the support block. The second threaded rod and the turbine rod are fixedly connected to each other. A warning label is meshed with the outer wall of the second threaded rod. The warning label is installed on the top of the waterproof shell in a sliding state.

[0020] In a preferred embodiment, the protective process of a bridge repair and reinforcement construction protection system comprises the following specific steps:

[0021] S1. First, the staff climbs onto the maintenance platform and drives the displacement mechanism to adjust the overall position of the main structure so that the maintenance platform fits against the outer wall of the pier. Then, by rotating the shaft, the positioning bolt is driven into the ground, which allows the displacement mechanism to drive the main structure to be stably limited. At the same time, the warning signs are driven upward by the rotating shaft to provide warnings on both sides of the displacement mechanism to alert pedestrians to the construction site.

[0022] S2. Then, by activating the telescopic electric cylinder to extend the platform, the staff can reach the maintenance point at a suitable height. The second support base plate between the two maintenance platforms is then locked to the first support base plate, so that the two maintenance platforms are stably assembled on the outer perimeter of the pier, allowing the staff to move freely on the outer perimeter of the pier.

[0023] S3. By activating the hydraulic telescopic rod, the circular enclosure frame is lowered to the outer wall of the maintenance platform to catch small gravel falling during construction. Simultaneously, the wear-resistant sliding sleeve is adjusted in the same position through the first and second support frames to make the first support rod more horizontal. Then, multiple support plates are laid flat at the bottom of the maintenance platform to form an enclosure to catch the falling objects and prevent workers from falling from height.

[0024] The technical effects and advantages of this invention are as follows:

[0025] 1. This invention provides a first support rod and a support plate that can be opened and closed at the bottom of the maintenance platform. When the first support rod and the support plate are unfolded, they are stably supported on the outer wall of the pier. The bottom of the maintenance platform is enclosed to catch falling stones, materials, tools or workers, thereby avoiding the problems of falling from heights and accidental injury to others. It also avoids the problem of low work efficiency caused by manual construction.

[0026] 2. This invention provides two maintenance platforms that can be enclosed on the outer wall of the bridge pier. After the two maintenance platforms are spliced ​​together on the outer wall of the bridge pier, the second support plate at the bottom of the corresponding first support plate is slid out and locked onto one side of the first support plate on top of the other maintenance platform. This allows the two maintenance platforms to be stably connected together. When the staff needs to adjust the maintenance position, they can move freely around the bridge pier without having to adjust the maintenance platform again. This avoids the problem of the platform shaking and accidentally injuring the staff when adjusting the maintenance platform.

[0027] 3. The present invention provides a second protective mechanism that can be adjusted up and down on the outer wall of the maintenance platform, which can simultaneously drive the expansion or contraction of the first protective mechanism. At the same time, it can also limit and hold the expanded first support rod and support plate, thereby enhancing the support stability of the support plate and making it more stable when catching people or materials that have fallen.

[0028] 4. This invention provides a rotatable and adjustable auxiliary limiting mechanism on one side of the displacement mechanism. When the auxiliary limiting mechanism stabilizes the overall position of the displacement mechanism, it can simultaneously drive the warning sign to move upward. This serves as a warning to pedestrians during construction and avoids the displacement mechanism from shaking due to external impacts during maintenance, thus protecting the personal safety of workers.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Refer to the instruction manual appendix Figure 1-10 An embodiment of the present invention provides a bridge repair and reinforcement construction protection system, such as... Figure 1 As shown, it includes the main body 1, combined with Figure 5-6As shown, the main structure 1 includes a support base 101. A telescopic electric cylinder 102 is fixedly installed on the top of the support base 101, and a maintenance platform 103 is fixedly installed on the top of the telescopic electric cylinder 102. The telescopic electric cylinder 102 is electrically connected to an external power source. The telescopic electric cylinder 102 is a YNT-04 series large lifting electric cylinder device. When in use, the telescopic electric cylinder 102 can be raised and lowered by starting it, thereby driving the height of the maintenance platform 103 to be adjusted. In actual use, when the telescopic electric cylinder 102 is in the lowest position, the staff climbs onto the maintenance platform 103 through an external ladder, and then places the maintenance platform 103 close to the outer wall of the bridge pier. The height of the maintenance platform 103 is then raised so that the staff can contact the bridge to carry out maintenance.

[0042] The top of the main structure 1 is fixedly equipped with the first protective mechanism 2, combined with Figure 6 As shown, the first protective mechanism 2 includes a telescopic rod 21 fixedly installed on the top of the support base 101. A connecting rod 22 is fixedly installed on the top of the telescopic rod 21. The connecting rod 22 is fixedly installed on the bottom of the maintenance platform 103. A limit sleeve 23 is fixedly installed on the outer wall of the telescopic rod 21. Multiple first support rods 24 are hinged in a ring-shaped manner at equal intervals on the outer wall of the limit sleeve 23. A support plate 25 is rotatably installed on the outer wall of each first support rod 24. The support plates 25 on the outer walls of every two first support rods 24 are hinged to each other. A second support rod 26 is hinged to the outer wall of each first support rod 24. A wear-resistant sliding sleeve 27 is hinged to the end of the second support rod 26 away from the first support rod 24. The wear-resistant sliding sleeve 27 is installed on the outer wall of the connecting rod 22 in a sliding up-and-down state. In use, as the telescopic electric cylinder 102 extends... The connecting rod 22 can be pulled simultaneously to extend the telescopic rod 21. Under normal conditions, the wear-resistant sliding sleeve 27 is close to the bottom of the maintenance platform 103. The first support rod 24 is tilted and supported on the outer wall of the limiting sleeve 23. The two hinged first protective mechanisms 2 are also folded and set on the outer wall of the limiting sleeve 23. When the wear-resistant sliding sleeve 27 is pressed down to move its position downward, the first support rod 24 is gradually turned into a horizontal state. At the same time, multiple support plates 25 can also be turned into a horizontal state and supported on the outer wall of the limiting sleeve 23. Thus, multiple first support rods 24 and support plates 25 are unfolded and supported on the bottom of the maintenance platform 103. During the maintenance process, falling stones or tools can be caught by unfolding the first support rods 24 and support plates 25 to avoid accidentally injuring pedestrians and staff on the bridge.

[0043] The main body 1 and the first protective mechanism 2 are each provided with a second protective mechanism 3. The second protective mechanism 3 is used to adjust the first protective mechanism 2 to open or close, and at the same time to provide a second enclosure for the outer wall of the main body 1. A displacement mechanism 4 is fixedly installed at the bottom of the main body 1, and an auxiliary limiting mechanism 5 is fixedly installed on one side of the displacement mechanism 4.

[0044] As a further expansion of this plan, combined with Figure 4 and Figure 6 As shown, a first support base plate 104 is fixedly installed on the top of the maintenance platform 103, and a second support base plate 105 is slidably installed on the bottom of the first support base plate 104. A first groove 106 is formed on the top of the second support base plate 105, and a limiting block 107 is fixedly installed on the bottom of the first support base plate 104. The limiting block 107 is slidably installed in the inner cavity of the first groove 106. The purpose of this arrangement is that, under normal conditions, the second support base plate 105 is retracted between the first support base plate 104 and the maintenance platform 103. When needed, by sliding the second support base plate 105 out from the bottom of the first support base plate 104, the second support base plate 105 extends beyond the bottom of the first support base plate 104, thereby expanding the usable range of the maintenance platform 103. The number of maintenance platforms 103 is at least... The system is configured with two support base plates. The first support base plate 104 is positioned at the horizontal centerline of the maintenance platform 103. A limit clamp 108 is fixedly installed on one side of the second support base plate 105, which is engaged with the outer wall of the first support base plate 104 on top of the other maintenance platform 103. The purpose of this configuration is to allow the second support base plate 105 to be placed between the two maintenance platforms 103 when the two maintenance platforms 103 are enclosed on the outer wall of the pier. This avoids gaps at the joint between the two maintenance platforms 103, which could lead to workers slipping and getting injured while repairing the bridge. Furthermore, it allows workers to move freely in a circular motion on top of the maintenance platform 103 when adjusting their position, making it more convenient for workers to perform maintenance at different locations at the joint between the bridge and the pier.

[0045] Furthermore, to enhance the stability of the first support rod 24 and the support plate 25 in catching falling objects, a rubber enclosure frame 28 is fixedly connected to one end of each of the first support rods 24. The rubber enclosure frame 28 is used to increase the enclosure depth of the first support rods 24 and the support plate 25, so that when an object falls onto the support plate 25, it can be blocked by the rubber enclosure frame 28 and will not easily fall off again. At the same time, to enhance the supporting stability of the first support rods 24 and the support plate 25, a first bracket 29 is hinged to the outer wall of each of two adjacent first support rods 24, and the two first support rods 24 are also connected to the support plate 25. Each bracket 29 is hinged with a second bracket 210. When the multiple first support rods 24 and support plates 25 are unfolded, the second brackets 210 set between the two first support rods 24 near the outer wall of the pier can bend the two first brackets 29 toward the limiting sleeve 23 by contacting the outer wall of the pier, thereby assisting in limiting the two first support rods 24. This allows the two first support rods 24 near the outer wall of the pier to be supported on the outer wall of the pier, thus preventing the unfolded first support rods 24 and support plates 25 from shaking and affecting actual use.

[0046] As a further expansion of this plan, refer to Figure 6 As shown, the second protective mechanism 3 includes a balance block 31 fixedly installed on the outer wall of the maintenance platform 103. A vertically arranged hydraulic telescopic rod 32 is fixedly installed on one side of the balance block 31. An annular enclosure frame 33 is fixedly connected to the bottom of the hydraulic telescopic rod 32. The annular enclosure frame 33 is slidably installed on the outer wall of the maintenance platform 103. Two limiting slide rods 35 are fixedly installed on the outer wall of the maintenance platform 103. The annular enclosure frame 33 is slidably installed on the outer wall of the two limiting slide rods 35. The annular enclosure frame 33 is used to provide further limiting protection for the perimeter of the maintenance platform 103. When the annular enclosure frame 33 is lowered, it can be used to enclose and collect materials around the construction site. When the annular enclosure frame 33 is raised, materials collected inside or fallen stones can be cleaned and removed for future use. In actual use, by starting... The hydraulic telescopic rod 32 allows the annular enclosure frame 33 to move downwards as a whole, thereby enabling the annular enclosure frame 33 to slide stably on the outer wall of the maintenance platform 103 and the limiting slide rod 35. At the same time, two inclined limiting chains 34 are fixedly installed at the bottom of the balance block 31. The limiting chains 34 are fixedly installed on the outer wall of the annular enclosure frame 33 and the outer wall of the rubber enclosure frame 28. The purpose of this arrangement is that after the rubber enclosure frame 28 is unfolded, the limiting chains 34 can limit and fix the support plate 25 as a whole again, thereby maintaining the stability of the support plate 25 during operation. When an object falls onto the top of the support plate 25, the limiting chains 34 can buffer and disperse the force on the support plate 25, thereby avoiding the problem of sudden damage to the support plate 25.

[0047] Simultaneously, a first support frame 36 is fixedly installed on the outer wall of the annular enclosure frame 33, and a second support frame 37 is fixedly installed on the outer wall of the first support frame 36. The second support frame 37 is fixedly installed on the outer wall of the wear-resistant sliding sleeve 27. The purpose of this arrangement is to enable the wear-resistant sliding sleeve 27 to slide on the outer wall of the connecting rod 22 synchronously when the annular enclosure frame 33 moves down as a whole, through the arrangement of the first support frame 36 and the second support frame 37, thereby limiting the flat unfolding of the first support rod 24 and the support plate 25.

[0048] In practice, workers first climb onto the maintenance platform 103 and move it to fit against the outer wall of the pier. Simultaneously, the telescopic cylinder 102 is extended, allowing the maintenance platform 103 to stably move upwards to the maintenance height. Then, by sliding the second support plate 105 and engaging it with one side of another first support plate 104, the two maintenance platforms 103 are joined together to enclose the outer wall of the pier. This allows workers to move freely between the two maintenance platforms 103, facilitating the maintenance of the pier and bridge. The maintenance position can be freely adjusted when repairing beams in different positions, so that the main body 1 can be moved again. Then, by activating the hydraulic telescopic rod 32 to extend it downward, when the ring enclosure frame 33 is pressed and pushed down, the wear-resistant sliding sleeve 27 is moved down to the outer wall of the connecting rod 22 through the first support frame 36 and the second support frame 37. Then, the first support rod 24 and the support plate 25 are unfolded flat, and the limit chain 34 is straightened and tightened. This allows the support plate 25 to be quickly unfolded at the bottom of 031 to protect against falling stones or workers.

[0049] As a further expansion of this plan, combined with Figure 9 As shown, the displacement mechanism 4 includes a first base 41 located at the bottom of the support platform 101. A caster wheel 42 is fixedly mounted on the top of the first base 41. This arrangement facilitates the movement of the main body mechanism 1 and also allows for adjustment of the distance between the support platform 101 and the outer wall of the pier. Figure 10As shown, a first threaded rod 43 arranged horizontally is rotatably mounted on one side of the first base 41. Multiple first supporting slide rods 44 are fixedly mounted on the bottom of the support platform 101. Threaded blocks 45 are fixedly mounted on the outer walls of each of the multiple first supporting slide rods 44. The threaded blocks 45 mesh with the outer walls of the first threaded rods 43. Multiple second sliding grooves 46 are opened on the top of the first base 41. The multiple first supporting slide rods 44 are slidably installed in the corresponding inner cavities of the second sliding grooves 46. In use, by rotating the first threaded rod 43, the threaded blocks 45 can be moved within their respective second sliding grooves 46. The outer wall is translated, and then, in conjunction with the first supporting slide rod 44 sliding in the inner cavity of the second slide groove 46, the supporting base 101 is moved to the top of the first base 41. This makes it more convenient to adjust the distance between the main body 1 and the pier. To enhance the stability of the supporting base 101 during its overall movement, a third slide groove 47 is provided on the top of the first base 41. A second supporting slide rod 48 is slidably installed on the top of the third slide groove 47. The second supporting slide rod 48 is fixedly installed at the vertical centerline of the supporting base 101. Simultaneously, in conjunction with... Figure 8 As shown, the number of first threaded rods 43 is at least two, and both first threaded rods 43 are rotatably installed inside the first base 41 and extend out of the outer wall of the first base 41. One end of the first threaded rod 43 extending out of the outer wall of the first base 41 is fixedly connected to a DC motor for driving its rotation. Gears 49 are fixedly installed on the outer wall of both first threaded rods 43 extending out of the first base 41. The outer walls of both gears 49 are meshed with synchronous belts 410. In actual use, when the first threaded rod 43 is rotated by starting the DC motor, the threaded block 45 can be translated on its outer wall, thereby causing the first supporting slide rod 44 to synchronously drive the support base 101 to translate, and then stop moving after the maintenance platform 103 contacts the outer wall of the pier.

[0050] Furthermore, to ensure that the main structure 1 remains stable after the two maintenance platforms 103 are stably positioned on the outer wall of the pier, refer to... Figure 7 As shown, the auxiliary limiting mechanism 5 includes a second base 51 fixedly installed on one side of the first base 41, and a waterproof shell 52 fixedly installed on one side of the second base 51, combined with... Figure 8As shown, a rotating shaft 53 is rotatably mounted between the waterproof shell 52 and the first base 41. A first support frame 54 is fixedly mounted on the outer wall of the rotating shaft 53. A second support frame 55 is fixedly mounted on the top of the first support frame 54, and a positioning bolt 56 is fixedly mounted on the bottom of the first support frame 54. Under normal conditions, the second support frame 55 moves into the gap between the first base 41 and the waterproof shell 52, at which time the positioning bolt 56 is located on the top of the second base 51. When the rotating shaft 53 is rotated, the second support frame 55 can rotate around the center of the rotating shaft 53 in a direction away from the second base 51, causing the positioning bolt 56 to... As the shaft gradually descends and contacts the ground, the positioning bolt 56 penetrates the soil and stops after the first support frame 54 flips and engages with one side of the second base 51, thus stably positioning the second base 51 on the ground. Simultaneously, a bevel gear 57 is fixedly connected to one end of the rotating shaft 53, which passes through the waterproof shell 52 and extends into its interior. A turbine rod 58 meshes with the outer wall of the bevel gear 57. A support block 59 is fixedly installed on the inner wall of the waterproof shell 52. The turbine rod 58 is rotatably mounted inside the support block 59, and a second threaded rod 510 is rotatably mounted on the top of the support block 59. The second threaded rod 510 and the turbine rod 58 are fixedly connected to each other, and a warning label 511 is engaged with the outer wall of the second threaded rod 510. The warning label 511 is installed on the top of the waterproof shell 52 in a sliding state. In use, by stabilizing the second base 51 and the first base 41 on the ground, the rotation of the shaft 53 synchronously drives the bevel gear 57 to rotate, which in turn causes the turbine rod 58 to drive the support block 59 to rotate. This causes the warning label 511 on its outer wall to move upward and extend out of the top of the waterproof shell 52 for early warning display, so as to inform passers-by that a small construction is underway. After construction is completed, the positioning bolt 56 is pulled out of the ground by rotating the shaft 53 in the opposite direction, and the second support frame 55 retracts into the space between the first base 41 and the waterproof shell 52. This allows the second base 51 to move again with the movement of the caster wheel 42. At the same time, the rotating shaft 53 can simultaneously reverse the bevel gear 57, which in turn causes the turbine rod 58 and the support block 59 to reverse, thereby causing the warning sign 511 to retract into the interior of the waterproof shell 52. This prevents the warning sign 511 from being exposed to the outside for a long time when not in use, thus avoiding damage and affecting the next display and warning use.

[0051] A protective process for a bridge repair and reinforcement construction protection system, the specific operation steps of which are as follows:

[0052] S1. First, the staff climbs onto the maintenance platform 103 and drives the displacement mechanism 4 to adjust the overall position of the main body 1 so that the maintenance platform 103 fits against the outer wall of the pier. Then, by rotating the shaft 53, the positioning bolt 56 is driven into the ground, which allows the displacement mechanism 4 to drive the main body 1 to be stably limited. At the same time, the warning sign 511 is driven upward by the rotating shaft 53 to provide warnings on both sides of the displacement mechanism 4 to alert pedestrians to the construction site.

[0053] S2. Then, by activating the telescopic electric cylinder 102 to extend the platform, the staff can reach the maintenance point at a suitable height. The second support base plate 105 between the two maintenance platforms 103 is then locked to the first support base plate 104, so that the two maintenance platforms 103 are stably assembled on the outer periphery of the pier, allowing the staff to move freely on the outer periphery of the pier.

[0054] S3. By activating the hydraulic telescopic rod 32, the annular enclosure frame 33 is lowered to the outer wall of the maintenance platform 103 to catch small gravel falling during construction. Simultaneously, the wear-resistant sliding sleeve 27 is adjusted in position through the first support frame 36 and the second support frame 37, so that the first support rod 24 tends to be horizontal. Then, multiple support plates 25 are laid flat at the bottom of the maintenance platform 103 to form an enclosure to catch the falling objects and prevent workers from falling from height.

[0055] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
