Description

Technical Field

[0001] This invention relates to the field of climbing formwork technology for bridge pier construction, specifically to a hydraulic triangular support lifting system for high piers. Background Technology

[0002] Climbing scaffolding is a platform facility used for the construction of high bridge piers. The applicant's new application 202411364188.8, filed in 2024, discloses a multi-functional construction platform for high bridge piers, including upper and lower main platforms. Each main platform is connected to a triangular load-bearing bracket, which is connected to the pier's pre-embedded load-bearing holes via positioning load-bearing pins. A lifting cylinder is installed on the triangular load-bearing bracket of the lower main platform, and the piston rod of the lifting cylinder is connected to the cylinder lug in the middle of the upper triangular load-bearing bracket. Using positioning load-bearing pins as the load-bearing foundation of the climbing scaffolding results in a simple structure, reduced risk of detachment, higher safety, and reusability. The triangular load-bearing bracket is an integral unit, simplifying the structure, facilitating connection with the lifting cylinder, and making operation more convenient. The entire climbing scaffolding structure has fewer components, is lightweight, has strong load-bearing capacity, and is easy to classify, store, and transport, thus saving on storage and transportation costs.

[0003] For climbing formwork structures, it is necessary to further improve the reliability and stability of the connection with the piers, simplify the load-bearing structure, shorten the construction time, and reduce production costs. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a high-pier hydraulic triangular support lifting system, which features simple structure, reliable connection, and ease of use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-pier hydraulic triangular support lifting system, comprising an upper triangular bearing mechanism, a lower triangular bearing mechanism, a pre-embedded bearing mechanism, and bearing fixing bolts. The lower triangular bearing mechanism is equipped with a lifting cylinder, and the piston rod of the lifting cylinder is connected to the cylinder lug in the middle of the upper triangular bearing mechanism. Each of the upper and lower triangular bearing mechanisms is fixedly connected to a pre-embedded bearing plate. The pre-embedded bearing mechanism is set inside the pier column and connected to the pre-embedded bearing plate through the bearing fixing bolts.

[0006] The load-bearing pre-embedded mechanism includes a pull-out plate, a pre-embedded connecting bolt, and a climbing cone. The pull-out plate is fixedly connected to the pre-embedded connecting bolt and embedded in the pier column. One end of the climbing cone is connected to the pre-embedded connecting bolt, and the other end is connected to the load-bearing fixing bolt.

[0007] The end of the climbing cone near the load-bearing fixing bolt is provided with a loading and unloading threaded hole.

[0008] Both ends of the upper triangular load-bearing mechanism and the lower triangular load-bearing mechanism are provided with guide and limiting components. The guide and limiting components include a mounting groove, a roller seat and a limiting post. The roller seat is set in the mounting groove and the circumferential surface of the roller seat abuts against the pier. An adjustment hole is opened on one side of the mounting groove, and the limiting post passes through the adjustment hole and is connected to the roller seat.

[0009] The upper triangular load-bearing mechanism is provided with an upper mounting flange, which is connected to the upper horizontal platform. The two ends of the upper horizontal platform are connected to the upper longitudinal platform.

[0010] The lower triangular load-bearing mechanism is provided with a lower connecting flange at its upper part. The lower connecting flange is connected to the lower horizontal platform, and the two ends of the lower horizontal platform are connected to the lower vertical platform.

[0011] The beneficial effects of this invention are:

[0012] 1. By setting up a load-bearing pre-embedded mechanism and embedding it into the concrete as a pre-embedded part, after the concrete has solidified, the pre-embedded load-bearing hanging plate is aligned with the hole position and the load-bearing fixing bolt is tightened, thus fixing the triangular load-bearing mechanism to the pre-embedded load-bearing mechanism. The reverse pull plate is fixedly connected to the pre-embedded connecting bolt. The reverse pull plate increases the contact area with the concrete, and the connection with the pre-embedded connecting bolt can better resist external loads and vibrations, thereby enhancing the stability and safety of the overall device connection with the pier column. At the same time, the corresponding bolts can be screwed into the loading and unloading threaded holes of the climbing cone to remove the climbing cone, reducing consumable parts.

[0013] 2. By setting a guide limit component, the rollers of the roller seat abut against the pier column, preventing the upper or lower triangular load-bearing mechanism of the lifting cylinder from directly contacting the pier column during the lifting process, which would cause wear and affect the service life.

[0014] 3. By setting up upper mounting flanges and lower connecting flanges, the connection method with the upper and lower horizontal platforms is simplified, making the components easier to install and effectively saving time and costs. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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.

[0023] The technical solution of the present invention will be described in detail below with reference to specific embodiments. The following specific embodiments may be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0024] Example 1

[0025] like Figures 1 to 5 As shown, the present invention provides a high-pier hydraulic triangular support lifting system, including an upper triangular load-bearing mechanism 1, a lower triangular load-bearing mechanism 2, a load-bearing pre-embedded mechanism 3, and load-bearing fixing bolts 4. The lower triangular load-bearing mechanism 2 is equipped with a lifting cylinder 5. The piston rod of the lifting cylinder 5 is connected to the cylinder lug 101 in the middle of the upper triangular load-bearing mechanism 1. The upper triangular load-bearing mechanism 1 and the lower triangular load-bearing mechanism 2 are each fixedly connected to a pre-embedded load-bearing hanging plate 6. The load-bearing pre-embedded mechanism 3 is set in the pier column 7 and connected to the pre-embedded load-bearing hanging plate 6 through the load-bearing fixing bolts 4.

[0026] Specifically, the load-bearing pre-embedded mechanism 3 includes a pull-back plate 301, a pre-embedded connecting bolt 302, and a climbing cone 303. The pull-back plate 301 is fixedly connected to the pre-embedded connecting bolt 302 and embedded in the pier column 7. One end of the climbing cone 303 is connected to the pre-embedded connecting bolt 302, and the other end is connected to the load-bearing fixing bolt 4. The end of the climbing cone 303 near the load-bearing fixing bolt 4 is provided with a loading and unloading threaded hole 304.

[0027] By setting up a load-bearing pre-embedded mechanism 3 and embedding it into the concrete as a pre-embedded part, after the concrete solidifies, the pre-embedded load-bearing hanging plate 6 is aligned with the hole position and the load-bearing fixing bolt 4 is tightened, thus fixing the triangular load-bearing mechanism to the pre-embedded load-bearing mechanism 3. The reverse pull plate 301 is fixedly connected to the pre-embedded connecting bolt 302. The reverse pull plate 301 increases the contact area with the concrete, and the connection with the pre-embedded connecting bolt 302 can better resist external loads and vibrations, thereby enhancing the stability and safety of the overall device connection with the pier column 7. At the same time, the corresponding bolts can be screwed into the loading and unloading threaded hole 304 of the climbing cone 303 to remove the climbing cone 303, reducing consumable parts.

[0028] Furthermore, both the upper triangular load-bearing mechanism 1 and the lower triangular load-bearing mechanism 2 are equipped with guide and limiting components 8 at their upper and lower ends. Each guide and limiting component 8 includes a mounting groove 801, a roller seat 802, and a limiting post 803. The roller seat 802 is positioned within the mounting groove 801, and the circumferential surface of the roller of the roller seat 802 abuts against the pier column 7. An adjustment hole 804 is provided on one side of the mounting groove 801, and the limiting post 803 passes through the adjustment hole 804 and connects to the roller seat 802. The abutment between the roller of the roller seat 802 and the pier column 7 creates a gap between the triangular load-bearing mechanism and the pier column, effectively preventing direct contact between the triangular load-bearing mechanism and the pier column, thus avoiding wear during the lifting process of the lifting cylinder 5 and affecting the service life of the triangular load-bearing mechanism.

[0029] Furthermore, the upper triangular load-bearing mechanism 1 is provided with an upper mounting flange 102, which is connected to the upper horizontal platform 9. The upper horizontal platform 9 is connected to the upper vertical platform 10 at both ends. The lower triangular load-bearing mechanism 2 is provided with a lower connecting flange 201, which is connected to the lower horizontal platform 11. The lower horizontal platform 11 is connected to the lower vertical platform 12 at both ends. By setting the upper mounting flange 102 and the lower connecting flange 201, the connection method with the upper horizontal platform 9 and the lower horizontal platform 11 is simplified, the components are easier to install, and time costs are effectively saved.

[0030] The working principle of this invention is as follows: During the pouring of bridge piers, the pre-embedded load-bearing mechanism 3 and the load-bearing fixing bolt 4 are assembled and embedded in the concrete. After complete solidification, the load-bearing fixing bolt 4 is removed. The hole of the pre-embedded load-bearing hanging plate 6 on the lower triangular load-bearing mechanism 2 is aligned with the pre-embedded hole. The load-bearing fixing bolt 4 is tightened to fix the lower triangular load-bearing mechanism 2. At this time, the upper triangular load-bearing mechanism 1 is lifted to the pre-embedded hole of the next segment by the lifting cylinder 5. The hole of the pre-embedded load-bearing hanging plate 6 on the upper triangular load-bearing mechanism 1 is aligned. The load-bearing fixing bolt 4 is tightened to fix the upper triangular load-bearing mechanism 1. At this time, the load-bearing fixing bolt 4 at the lower triangular load-bearing mechanism 2 is removed. The lifting cylinder 5 retracts to move the lower triangular load-bearing mechanism 2 upward. After reaching the predetermined hole position, the lower triangular load-bearing mechanism 2 is fixed. One cycle of climbing is completed. The climbing is repeated in this way to climb to the set position.

[0031] In addition to the preferred embodiments described above, there are other embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection claimed by the present invention.
