Description

Technical Field

[0001] The present invention relates to the technical field of cap beam support protection, and in particular to a safety protection device and an installation method for the construction of a large cantilever concrete cap beam support. Background Art

[0002] A highway refers to a public road that can be used for driving between cities, between urban and rural areas, and in the countryside, which has been approved by the transportation authority. It includes highways that have been built and approved by the transportation authority. During the construction of the highway, personnel will plan the route of the highway, and then the construction team will carry out the construction. During the planning process, the highway may encounter mountains or fields. For this part of the highway, due to its topography, the highway cannot be built directly. Therefore, people will first build a cap beam assembly during the construction process, and lay the highway on the upper side of the cap beam assembly. When the cap beam assembly is constructed, the concrete of the support is generally poured first, and then the cap beam is poured on the upper side of the support. The pouring height of the support is related to the topography and the planned route. When the pouring height of the support is too high, since the support cannot be directly molded and demolded by humans, people will pour it according to the height of the support. A protective platform is installed on the bracket at a high height. On the one hand, this protective platform can be used as a workbench for people, and on the other hand, it can prevent items from falling from the bracket during the construction process. However, there are some problems with the existing protection when it is used. Generally, the height of the bracket is gradually cast, and the protective platform is generally manually spliced ​​on the lower side of the bracket during installation. However, as the bracket gradually increases, when the bracket is built to a certain height, the protective platform needs to be manually removed and moved upward, and this is repeated until the bracket is completed. This type of construction can protect the bracket and provide convenience for the construction workers, but this type of construction method will cause the construction workers to disassemble and install it many times, and as the height of the device becomes higher and higher, the safety of the construction will become lower and lower, which will lead to a decrease in the practicality of the device when in use, and it is impossible to fully protect the personnel and the bracket, which invisibly reduces the efficiency of construction.

[0003] The invention with patent number CN115928591A discloses a temporary working protection platform for the final construction of the cap beam, including a platform bracket, a supported base plate, a leak-proof base plate and a supporting foot frame. The platform bracket includes two vertical protective plates and two load-bearing rods. The two vertical protective plates are arranged at intervals in the horizontal direction. The two load-bearing rods are respectively located at the bottom of the two ends of the platform bracket. The load-bearing rods are respectively fixedly connected to one of the vertical protective plates, so that the two vertical protective plates and the two load-bearing rods jointly surround the rising avoidance through hole. The rising avoidance through hole is used to accommodate the formed cap beam and enable the platform bracket to be away from the formed cap beam in the height direction when dismantled. The supported base plate includes two supported branch base plates that are independent of each other and mirror-set. The two ends of the supported branch base plates are respectively provided with downwardly protruding limit blocks, and the supported base plate is overlapped on the two load-bearing rods. The above invention also has the problems of insufficient protection and the need for multiple installation and disassembly.

[0004] Therefore, in order to solve the above problems, the present invention designs a safety protection device and installation method for the construction of a large cantilever concrete cap beam support to solve the above problems. Summary of the Invention

[0016] (a) When the supports in the cap beam assembly are built to a certain height, the device is installed on both sides of the cap beam assembly, and the two bottom plates surround the cap beam assembly. The bottom plates are fixed by hammering the stabilization mechanism, and then the first connecting mechanism and the second connecting mechanism are adjusted to surround the supports and position the supports between the two bottom plates.

[0017] (b) After the device is installed, continue to build the bracket. When the bracket is built to a certain height, control the driving mechanism to drive the lifting mechanism so that the construction height of the protective platform and the bracket are always kept consistent. When the bracket is built to a certain height, cast the cap beam in the cap beam assembly, and then control the first fixing mechanism and the second fixing mechanism and the rotating plate to disengage. When the first fixing mechanism and the second fixing mechanism and the rotating plate are disengaged, the rotating shaft slides in the slide groove. When the two rotating plates fall, the gap formed by the two rotating plates falling can adapt to the width of the cap beam, and then the driving mechanism can continue to be controlled to lift the protective platform, so as to always ensure that the device can protect the cap beam assembly.

[0018] The above technical solution has the following advantages or beneficial effects:

[0019] The present invention uses the two bottom plates in the device to work together. When the device is not working, the lifting mechanism can be stored to separate the two protective platforms from each other, which can reduce the space occupied by the device and make the device more convenient to transport.

[0020] When the device is in use, the base plate and the protective platform can be connected by the first connecting mechanism and the second connecting mechanism, so that the device is spliced ​​into a whole. The bracket is located between the base plate and the protective platform. The protective platform can serve as a workbench to prevent the bracket from falling during the construction process, such as construction steel bars, and causing injuries to the workers below.

[0021] During the operation of the device, as the bracket gradually increases in height, the driving mechanism and the lifting mechanism can be directly controlled to cooperate, so that the protective platform can synchronously follow the height change of the bracket. As a result, during the construction process of the bracket, there is no need to repeatedly disassemble the protective platform, so that the protective platform can fully protect the bracket and ensure the safety of workers working at height;

[0022] When the support is built to a certain height, a cap beam is built on the support. The space inside the protective platform can be changed directly by changing the position of the rotating plate, so that the device can adapt to a cap beam with a larger width, thereby reducing manual operation steps and workload and improving work efficiency.

[0023] After the bracket and cap beam are built, they can be reset by controlling the lifting mechanism, and the device can be disassembled by disconnecting the connected parts, making the device more efficient and convenient during installation and disassembly, while improving safety and work efficiency, further enhancing the practicality and convenience of the device.

[0034] like Figures 1 to 7As shown, this specific embodiment adopts the following technical solutions: a safety protection device for the construction of a large-arm concrete cap beam support, including a base, a protection platform assembly, a driving mechanism 6, a lifting mechanism 11 and a stabilizing device; wherein: the base includes two bottom plates 1, and the two bottom plates 1 are movably connected by a plurality of first connecting mechanisms 2; the protection platform assembly is located above the base 1, and is two, each including a protection platform 16 and a rotating plate 18 rotatably connected to one side of the protection platform 16, and the two protection platforms 16 are movably connected by a plurality of second connecting mechanisms 17; the driving mechanism 6 is arranged On the base plate 1; the lifting mechanism 11 is arranged between the base plate 1 and the protective platform 16, and the driving mechanism 6 drives the lifting mechanism 11 to drive the protective platform assembly closer or farther away from the base; the stabilizing device includes a first fixing mechanism 21, a second fixing mechanism 24, a connecting frame 27 and an anti-slip assembly 33. The first fixing mechanism 21 is arranged between the protective platform 16 and the rotating plate 18, the second fixing mechanism 24 is arranged on the bottom surface of the protective platform 16, a connecting frame 27 is provided between the second fixing mechanism 24 and the first fixing mechanism 21, and an anti-slip assembly 33 is provided between the connecting frame 27 and the protective platform 16.

[0035] Among them, the driving mechanism 6 includes a bidirectional screw 7, a driving motor 8, a driving gear 9, a transmission assembly 37 and a reversing wheel 10. The bidirectional screw 7 is rotatably connected in the two base plates 1, one of the bidirectional screws 7 is connected to the self-locking assembly 32, and the other bidirectional screw 7 is connected to the output end of the driving motor 8. A driving gear 9 is provided on the base plate 1, and the driving gear 9 is meshed with the transmission assembly 37. The transmission assembly 37 transmits and connects the driving gear 9 and the bidirectional screw 7. A reversing wheel 10 is provided on one of the base plates 1, and the reversing wheel 10 is located between the two driving gears 9 and meshes with the two driving gears 9. When the protective platform 16 needs to be lifted, the drive motor 8 is controlled to rotate. At this time, the drive motor 8 controls the bidirectional screw 7 to rotate, and at the same time, the drive gear 9 drives the reversing wheel 10 to rotate. When the reversing wheel 10 rotates, the two bidirectional screws 7 rotate at the same time. When the bidirectional screw 7 rotates, the lifting mechanism 11 on the bidirectional screw 7 moves, and then the drive mechanism 6 can cooperate with the lifting mechanism 11 to lift the protective platform 16 when the device is working, so that the device can use the height of the bracket, further improving the practicality of the device.

[0036] Among them, the lifting mechanism 11 includes a moving block 12, a first connecting arm 13, a second connecting arm 14 and a hydraulic rod 15. Two moving blocks 12 are threadedly connected to the bidirectional screw 7 in the driving mechanism 6. The moving block 12 is slidably connected to the movable groove opened in the base plate 1. The moving block 12 is rotatably connected to the first connecting arm 13, and the first connecting arm 13 is rotatably connected to the second connecting arm 14. A hydraulic rod 15 is provided between the first connecting arm 13 and the second connecting arm 14. One end of the hydraulic rod 15 is connected to the first connecting arm 13, and the other end is connected to the second connecting arm 14. A protective platform 16 is arranged on the second connecting arm 14, and the protective platform 16 and the second connecting arm 14 are installed together through a connecting assembly. When the hydraulic rod 15 is extended, the hydraulic rod 15 pushes the first connecting arm 13 and the second connecting arm 14 to move away from each other, thereby increasing the angle between the first connecting arm 13 and the second connecting arm 14, and then raising the height of the protective platform 16. When the driving mechanism 6 controls the two moving blocks 12 to move away from each other, the height of the protective platform 16 can be further increased. On the contrary, when the two moving blocks 12 approach each other, the position of the protective platform 16 drops, thereby ensuring that the lifting height of the device always adapts to different brackets and cap beams when it is working, further improving the stability of the device.

[0037] Among them, sliding grooves 19 are opened on the front and rear sides of the rotating plate 18, and the rotating shaft 20 is slidably connected in the sliding groove 19. The rotating shaft 20 is rotatably connected to the protective platform 16. The rotating plate 18 and the protective platform 16 are connected through the rotating shaft 20. When the rotating shaft 20 rotates in the sliding groove 19, one end of the two rotating plates 18 falls, so that the rotating plate 18 and the protective platform 16 are in a vertical state. The two rotating plates 18 fall to form a gap to accommodate the cap beam assembly 34.

[0038] Among them, the first connecting mechanism 2 includes a connecting block 3, a bidirectional screw 4, a fixed block 36 and a rotating block 5. A plurality of slots are provided on the base plate 1. The connecting block 3 is movably connected in the slots. The bidirectional screw 4 is threadedly connected between the two connecting blocks 3. The rotating block 5 is installed on the bidirectional screw 4. A fixed block 36 is provided in the middle position of the slot. The fixed block 36 is threadedly connected to the bidirectional screw 4, providing support for the bidirectional screw 4 to drive the connecting block 3 to move. After the base plate 1 is fixed, the connecting block 3 is fixedly connected in the slot, and then the rotating block 5 is rotated. At this time, the bidirectional screw 4 rotates. When the bidirectional screw 4 rotates, the bidirectional screw 4 drives the two connecting blocks 3 closer to each other, thereby effectively improving the stability of the two base plates 1. When the device is disassembled, the bidirectional screw 4 can be rotated in the opposite direction to disassemble the device, further improving the stability of the device.

[0039] The second connecting mechanism 17 has the same structure as the first connecting mechanism 2. A guardrail 35 is provided on the protective platform 16, which also has multiple slots for placing items. The second connecting mechanism 17 connects the two protective platforms 16, effectively improving their stability. The guardrail 35 effectively protects personnel on the protective platforms 16 from falling, further enhancing the safety of the device.

[0040] The first fixing mechanism 21 includes a slide bar 22 and a spring 23. The slide bar 23 is slidably connected to the interior of the rotating plate 18. Both ends of the slide bar 23 extend through the protective platform 16. The spring 23 is sleeved on the end of the slide bar 22 and located outside the protective platform 16. The elastic force of the spring 23 acts on the slide bar 22, and the slide bar 22 is inserted between the rotating plate 18 and the protective platform 16, thereby effectively fixing the rotating plate 18 and preventing the rotating plate 18 from changing position. When the first fixing mechanism 21 and the rotating plate 18 are disengaged, the rack 26 moves at the same time. When the rack 26 moves, the rack 26 drives the force-bearing plate 25 to rotate. When the force-bearing plate 25 rotates to a certain angle, the force-bearing plate 25 and the rotating plate 18 are disengaged. At this time, the rotating plate 18 is pulled to rotate on the rotating shaft 20, so that the rotating plate 18 can be deformed from a horizontal state to a vertical state. When the rotating plate 18 is not in use, the upper side of the entire protective platform 16 is intact, which can effectively improve the protection safety of the protective platform 16. When the rotating platform rotates, the protective platform 16 can adapt to the cap beam, further improving the stability and practicality of the device.

[0041] Among them, the second fixing mechanism 24 includes a force-bearing plate 25 and a rack 26. One end of the force-bearing plate 25 with a gear is rotatably connected to the bottom surface of the protective platform 16, and the other end of the force-bearing plate extends to the lower side of the rotating plate 18. The bottom surface of the protective platform 16 is slidably connected to multiple racks 26. The racks 26 and the force-bearing plate 25 are meshed with each other. One end of the rack 26 extending from the protective platform 16 is connected to the connecting frame 27. When the device needs to adjust the position of the rotating plate 18, the connecting rod is pulled. At this time, the slide bar 22 and the rotating plate 18 are disengaged. When the position of the rotating plate 18 is disengaged, the spring 23 is first compressed. Then, when the anti-detachment component 33 is controlled, the position of the slide bar 22 is fixed. At this time, the second fixing mechanism 24 can be adjusted. The mutual cooperation of the first fixing mechanism 21 and the second fixing mechanism 24 can ensure the stability of the rotating plate 18 and prevent the rotating plate 18 from falling off during use, thereby further improving the stability of the device.

[0042] The four corners of the base plate 1 are equipped with stabilizing mechanisms 28, which include ground spikes 29 and expansion blocks 30. The ground spikes 29 are slidably connected to the base plate 1. The underside of the ground spikes 29 is conical and has barbs on its surface. The bottom surface of the base plate 1 is also equipped with multiple protrusions 31. The base plate 1 is placed in the appropriate position, and the expansion blocks 30 are hammered. The ground spikes 29 are driven into the ground, and the protrusions 31 are also driven into the ground. Because the ground spikes 29 are equipped with barbs, the fixing plate is more stable when the ground spikes 29 are fixed, further improving the stability of the device during fixing, thereby improving the safety of the device. Example 2

[0043] In order to better implement the technical solution of the present invention, the present invention also provides a method for installing a large cantilever concrete cap beam support, such as Figures 1 to 7 As shown, this specific embodiment adopts the following installation method:

[0044] (a) When the brackets in the cap beam assembly 34 are built to a certain height, the devices are placed on both sides of the cap beam assembly 34, and the two bottom plates 1 surround the cap beam assembly 34. The bottom plates 1 are fixed by hammering the stabilizing mechanism 28. The first connecting mechanism 2 and the second connecting mechanism 17 are then adjusted to surround the brackets and position them between the two bottom plates 1. The two protective platforms 16 are connected, and the brackets are simultaneously surrounded. At this time, the rotating plate 18 and the protective platform 16 are in a horizontal state.

[0045] b After the installation of the device is completed, continue to build the bracket. When the bracket is built to a certain height, control the driving mechanism 6 to drive the lifting mechanism 11 so that the construction height of the protective platform 16 and the bracket are always kept consistent. When the bracket is built to a certain height, cast the cap beam in the cap beam assembly 34, and then control the first fixing mechanism 21 and the second fixing mechanism 24 and the rotating plate 18 to disengage. When the first fixing mechanism 21 and the second fixing mechanism 24 and the rotating plate 18 are disengaged, the rotating shaft 20 slides in the slide groove 19. When the two rotating plates 18 fall, the gap formed by the two rotating plates 18 falling can adapt to the width of the cap beam, and then the driving mechanism 6 can continue to be controlled to lift the protective platform 16, so as to always ensure that the device can protect the cap beam assembly 34.

[0046] By adopting the above technical solution, the present invention can store the lifting mechanism 11 when not in use, and the two protective platforms 16 can be separated from each other, thereby reducing the space occupied by the device and making the device more convenient to transport.

[0047] During operation, the base plate 1 and the protective platform 16 can be connected by the first connecting mechanism 2 and the second connecting mechanism 17, so that the device is spliced ​​into a whole. The bracket is located between the base plate 1 and the protective platform 16. The protective platform 16 can serve as a workbench to prevent the bracket from falling during the construction process and causing injuries to the workers on the lower side due to the falling of construction steel bars;

[0048] During the operation of the device, as the bracket gradually increases in height, the driving mechanism 6 and the lifting mechanism 11 can be directly controlled to cooperate so that the protective platform 16 can synchronously follow the height change of the bracket. Therefore, during the construction process of the bracket, there is no need to repeatedly disassemble the protective platform 16, and the protective platform 16 can fully protect the bracket. At the same time, the increase in the height of the bracket increases the working environment of the staff accordingly, which can ensure the safety of the staff.

[0049] When the support is built to a certain height, a cap beam is built on the support. By directly changing the position of the rotating plate 18 and the space inside the protective platform 16, the device can also adapt to a wider cap beam, reducing the operating steps and workload of the staff and improving work efficiency.

[0050] After the construction of the bracket and the cap beam is completed, the lifting mechanism 11 is controlled to reset, and the connected parts can be disconnected to disassemble the device, making the device more convenient and more effective during installation and disassembly, and improving the safety, work efficiency, practicality and convenience of the device.

[0051] Although the above describes the specific implementation methods of the invention in conjunction with the accompanying drawings, it does not limit the scope of protection of the invention. Based on the technical solution of the present invention, various modifications or variations that can be made by those skilled in the art without creative work are still within the scope of protection of the present invention.
