Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering technology, specifically to a hydraulic climbing formwork device for dam deck surfaces. Background Technology

[0002] The construction of cast-in-place dams in water conservancy projects usually involves manual handling and assembly of formwork layer by layer, which is inefficient, extremely labor-intensive, and results in inconsistent and unreliable construction quality.

[0003] Chinese Patent No. CN 224063432 U discloses a dam concrete pouring formwork lifting device, including a combined steel formwork. A support plate is fixedly connected to the upper surface of the combined steel formwork, and a guardrail (A-shaped) is fixedly connected to one side of the support plate. A steel frame is fixedly connected to the other side of the upper surface of the combined steel formwork. In use, after the foundation excavation of the grouting cover plate is completed, a winch is installed at the top of the foundation with counterweights. The combined steel formwork is connected by steel ropes, and the winch is used to move the combined steel formwork to the concrete pouring position. After the counterweights are determined, the formwork counterweight blocks are installed and fixed on the combined steel formwork. After the concrete pouring is completed, the formwork counterweight blocks are removed, and the winch is used to lift the combined steel formwork to the next pouring section and fix it. After the combined steel formwork is lifted, a specialist is dispatched to the operating platform to perform finishing work on the previous pouring section.

[0004] However, existing formwork lifting devices require manual operation, repeated disassembly and assembly of the formwork, poor process coordination, low efficiency in formwork installation and lifting, and difficulty in controlling construction quality.

[0005] Therefore, how to effectively improve the efficiency, stability, and reliability of template installation and lifting on the dam deck has become an urgent problem to be solved in this field. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the purpose of this invention is to provide a highly efficient and stable hydraulic climbing formwork device for dam deck surfaces.

[0007] To achieve the above objectives, the present invention provides a hydraulic climbing formwork device for dam decks, comprising a top platform, a lifting system, a formwork system, a traveling support system, and a control system. The traveling support system is detachably installed on both sides of the dam surface; the bottom of the top platform is equipped with several outriggers, which are supported by the traveling support system and the dam surface respectively through a lifting system; the outriggers can move axially along the dam surface through the traveling support system, and can also move along the top platform to adapt to the cross-sectional changes of the dam surface; the template system is set on the traveling support system and can move relative to the traveling support system, dynamically conforming to the dam surface; the lifting system can lift the outriggers and cooperate with the traveling support system to lift the top platform and template system layer by layer; the control system can control the operating conditions of the lifting system, template system, traveling support system and outriggers.

[0008] Furthermore, the top platform is composed of several Bailey frame modules that can be detachably assembled.

[0009] Furthermore, the walking support system includes a support frame and a translation track. The support frame is arranged on both sides of the dam surface, and the translation track is arranged on the support frame and distributed along the axial direction of the dam surface.

[0010] Furthermore, embedded parts for cooperating with the support frame are distributed on both sides of the dam surface.

[0011] Furthermore, the support frame and embedded parts are configured as a detachable anchoring connection.

[0012] Furthermore, several outriggers are respectively arranged on the outer and inner periphery of the top platform to form an outer outrigger group and an inner outrigger group. The outer outrigger group is slidably mounted on the walking support system, and the inner outrigger group is mounted on the dam surface.

[0013] Furthermore, a horizontal slide rail is provided below the top platform, and the support legs corresponding to the downstream side of the dam deck are slidably mounted on the horizontal slide rail.

[0014] Furthermore, the outer support leg assembly and the inner support leg assembly can alternately support the top platform during the lifting and climbing process.

[0015] Furthermore, the template system includes a support base, a drive rod, and a template body. The support base is mounted on the walking support system, and one end of the drive rod is connected to the support base, while the other end is connected to the template body, enabling the template body to move.

[0016] Furthermore, the template body extends axially along the dam surface.

[0017] The hydraulic climbing formwork device for dam surfaces provided by this invention, through the coordinated operation of a lifting system and a traveling support system, enables the top platform and the formwork system to climb synchronously layer by layer. The outriggers at the bottom of the top platform can not only move along the axial direction of the dam surface with the traveling support system, but also adjust their position relative to the top platform, flexibly adapting to the cross-sectional changes of the dam surface and realizing continuous and uninterrupted climbing formwork construction. At the same time, the formwork system can move relative to the traveling support system to complete the precise fitting and positioning with the dam surface and the smooth demolding operation, effectively improving the efficiency of formwork assembly and disassembly and the overall climbing operation, and ensuring the stable operation of the climbing formwork device and the safe and reliable construction.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to specific illustrations.

[0022] See Figures 1 to 4 The image shows an example of a hydraulic climbing formwork device for dam decks provided by the present invention.

[0023] As shown in the figure, the hydraulic climbing formwork device for the dam surface in this example mainly includes a top platform 1, a lifting system 2, a formwork system 3, a walking support system 4, and a control system.

[0024] The walking support system 4 is detachably installed on both sides of the dam surface 5; the bottom of the top platform 1 is equipped with several support legs 6, which are supported by the walking support system 4 and the dam surface 5 respectively through the lifting system 2; the support legs can move axially along the dam surface 5 through the walking support system 4, and can also move along the top platform 1 to adapt to the cross-sectional changes of the dam surface 5; the formwork system 3 is set on the walking support system 4 and can move relative to the walking support system 4, dynamically fitting with the dam surface 5; the lifting system 2 can lift the support legs 6, and cooperate with the walking support system 4 to lift the top platform 1 and the formwork system 3 layer by layer; the control system can control the operating conditions of the lifting system 2, the formwork system 3, the walking support system 4 and the support legs 6; it can effectively improve the efficiency of formwork assembly and disassembly and overall climbing operations, and ensure the stable operation of the climbing formwork device and the safe and reliable construction.

[0025] Combination Figure 4 The top platform 1 includes several Bailey bridge modules 11, which can be disassembled and assembled to form the overall top platform 1, thus forming a modular and detachable top platform 1 structure that can be adaptively adjusted according to the overall width of the dam deck 5.

[0026] In conjunction with this, the top platform 1 is equipped with a concrete placing boom 7, which can deliver concrete to the pouring area inside the formwork to realize the on-site pouring operation of the dam. Here, the concrete placing boom 7 is a conventional technical means in this field, and will not be described in detail.

[0027] Combination Figure 5 Furthermore, the walking support system 4 includes a support frame 41, which is respectively set on both sides of the dam surface 5. Correspondingly, embedded parts 51 are evenly distributed on both sides of the dam surface 5 to cooperate with the support frame 41. Preferably, the embedded parts 51 include a number of embedded anchor bars embedded in the concrete at the side end of the dam surface 5, so that the support frame 41 is stably connected to the side end of the dam surface 5 through the embedded parts 51, providing a stable support platform for the climbing formwork device.

[0028] Meanwhile, the support frame 41 and the dam surface embedded part 51 are configured to be detachably anchored. When the device is lifting the climbing formwork, the walking support system 4 can be detached from the embedded part 51 of the lower dam surface and anchored to the embedded part 51 of the upper dam surface.

[0029] The walking support system 4 also includes a horizontal track 42, which is set on the support frame 41 and distributed along the axial direction of the dam surface 5, so that the support legs 6 at the bottom of the top platform 1 can move on the horizontal track 42, thereby enabling the climbing formwork device to move along the axial direction of the dam surface 5 to cover the outer formwork installation area of ​​the dam surface 5, thus ensuring the installation efficiency of the formwork.

[0030] Combination Figures 2 to 4 In coordination with this, several legs 6 at the bottom of the top platform 1 are respectively arranged in the outer and inner peripheral areas of the top platform 1. Preferably, four legs 6 are arranged circumferentially in the outer area of ​​the bottom of the top platform 1, and four legs 6 are also arranged axially in the inner area, so as to form an outer leg group 61 and an inner leg group 62.

[0031] The outer support leg assembly 61 is slidably mounted on the horizontal track 42 via the lifting system 2, while the inner support leg assembly 62 is mounted on the dam surface 5 via the lifting system 2. This allows the outer support leg assembly 61 and the inner support leg assembly 62 to cooperate with each other to stably support the top platform 1. Furthermore, the outer support leg assembly 61 can move axially along the horizontal track 42, and drive the inner support leg assembly 62 and the top platform 1 to move synchronously along the dam surface 5, ensuring that the installation area of ​​the template covers the side end face of the dam surface 5.

[0032] Furthermore, a horizontal slide rail 12 is provided below the top platform 1. The horizontal slide rail 12 is arranged in the downstream area of ​​the dam surface 5, and the legs of the outer support leg group 61 and the inner support leg group 62 corresponding to the downstream of the dam surface 5 are respectively slidably set on the horizontal slide rail 12.

[0033] For example, in this example, the two legs in the outer support leg group 61 corresponding to the downstream side of the dam surface 5, and the two legs in the inner support leg group 62 corresponding to the downstream side of the dam surface 5 are slidably mounted on the horizontal slide rail 12, so that the four legs corresponding to the downstream area can move horizontally along the horizontal slide rail 12 and slide into the dam surface 5 to reduce the distance between the two relative support legs. The distribution positions of the outer support leg group 61 and the inner support leg group 62 can be adjusted synchronously to adapt to the cross-sectional changes of the dam surface 5.

[0034] At the same time, the horizontal movement of the support legs downstream of the dam surface 5 can drive the support frame 41 to move horizontally in sync, ensuring that the support frame 41 can always fit against both sides of the dam surface 5 during the jacking and climbing formwork process, and ensuring that the formwork system 3 on the support frame 41 can be stably and tightly fitted against both sides of the dam surface 5, so as to complete the precise positioning and installation of formwork at different elevation positions, and adapt to the continuous climbing formwork construction of the dam variable cross section surface.

[0035] In conjunction with this, the lifting system 2 is installed at the bottom of each support leg 6, which can lift the corresponding support leg 6, thereby raising the top platform 1, and driving the top platform 1 and the formwork system 3 to be raised layer by layer on the dam surface 5, so as to realize continuous climbing formwork operation.

[0036] Preferably, the lifting system 2 can be composed of hydraulic jacks.

[0037] Combination Figures 6 to 8 Furthermore, the template system 3 is set on the walking support system 4 on both sides and can move relative to the walking support system 4 to adjust its position and posture, so as to realize the rapid positioning and demolding of the templates on both sides of the dam surface 5, eliminating the repeated disassembly and assembly of the templates and effectively improving construction efficiency.

[0038] Specifically, the template system 3 includes a support base 31, a drive rod 32, and a template body 33. The support base 31 is mounted on the support frame 41, and a moving device 34 is also provided on the support base 31. The moving device 34 is connected to the drive rod 32 and the template body 33 respectively, and can drive the drive rod 32 and the template body 33 to move along the support base 31 to get closer to the side of the dam surface 5, so as to ensure that the template body 33 can be accurately positioned.

[0039] Preferably, the top surface of the support base 31 is provided with a rack 311, and the middle area of ​​the moving device 34 is provided with a drive gear 341 that meshes with the rack 311. One end of the moving device 34 near the dam surface 5 is hinged to the template body 33, and the other end is hinged to the drive rod 32, so that the drive gear 341 meshes with the rack 411 to drive the drive rod 32 and the template body 33 to move synchronously along the support base 31. Furthermore, the drive rod 32 is preferably composed of a hydraulic drive rod, and its output end is hinged to the template body 33, so that the extension and retraction of the drive rod 32 can drive the template body 33 to move.

[0040] Based on the above structure, the extension and retraction of the drive rod 32 can drive the template body 33 to rotate around the moving device 34 towards the dam surface 5, thereby closely fitting the side end of the dam surface 5 with different inclination angles, adapting to dam surface 5 with different cross sections, ensuring that the template fits tightly and has high installation accuracy.

[0041] At the same time, the drive rod 32 can also extend and retract in the opposite direction to drive the template body 33 to rotate around the moving device 34 away from the dam surface 5, so as to disengage from the side of the dam surface 5 and achieve rapid demolding, thereby realizing the integrated operation of automatic and accurate template positioning and rapid demolding.

[0042] To ensure the stability and reliability of this climbing formwork device, it also includes a control system. The control system can coordinate the operation of the lifting system 2, the formwork system 3, the walking support system 4, and the outriggers 6, thereby effectively improving the efficiency of formwork disassembly and assembly and the overall climbing operation, and ensuring the smooth operation of the climbing formwork device and the safety and reliability of construction.

[0043] As an example, after the concrete pouring of the lower dam surface is completed, the formwork system 3 can drive the formwork body 33 to detach from the side of the dam surface 5, so as to achieve rapid demolding and ensure that the formwork body 33 maintains a safe distance from the dam surface 5 and does not interfere with the dam body and the frame of this device throughout the process.

[0044] Furthermore, the inner support leg assembly 62 is stably supported on the lower dam surface, serving as the main load-bearing point of the entire device; the support frame 41 and the embedded part 51 on the lower dam surface are removed to release the support frame 4 from the lower dam surface, and the inner support leg assembly 62 temporarily bears the load.

[0045] Next, multiple sets of hydraulic jacks in the lifting system 2 are started simultaneously, lifting the outer support leg group 61 evenly upwards. This causes the outer support leg group 61 to drive the support frame 41, horizontal track 42, template system 3, and top platform 1 to climb upwards by one standard floor height, reaching the upper dam surface.

[0046] At this point, the support frame 41 is connected and anchored to the embedded part 51 on the upper dam surface, completing the connection between the upper walking support system 4 and the dam body.

[0047] Furthermore, the lifting system 2 lowers the outer support leg assembly 61 back onto the support frame 41 and retracts the inner support leg assembly 62, separating it from the lower dam surface, so that the main stress points of the entire device are switched to the outer and outer support leg assemblies 61 and the walking support system 4.

[0048] The template system 3 can drive the template body 33 to move along the support base 31 and approach the side of the dam surface 5, ensuring that the template body 33 is accurately positioned on the upper dam surface and that concrete is poured on the upper dam surface.

[0049] Therefore, before climbing, the embedded parts of the lower dam surface are removed, and after climbing to the position, the embedded parts of the upper dam surface are connected. The outer support leg group 61 and the inner support leg group 62 are used to alternately support the main body of the device to ensure the stability and safety of the lifting and climbing formwork.

[0050] The hydraulic climbing formwork device for dam surfaces provided by this invention, through the coordinated operation of the lifting system 2 and the traveling support system 4, enables the top platform 1 and the formwork system 3 to climb synchronously layer by layer. The outriggers 6 at the bottom of the top platform 1 can not only move along the axial direction of the dam surface 5 with the traveling support system 4, but also adjust their position relative to the top platform 1, flexibly adapting to the cross-sectional changes of the dam surface 5, and realizing continuous and uninterrupted climbing formwork construction. At the same time, the formwork system 3 can move relative to the traveling support system to complete the precise fitting and positioning with the dam surface and the smooth demolding operation, effectively improving the efficiency of formwork assembly and disassembly and the overall climbing operation, and ensuring the stable operation of the climbing formwork device and the safe and reliable construction.
