Description

Technical Field

[0001] This utility model belongs to the technical field of pier hoisting equipment, specifically relating to a hoisting device for a dam concrete observation pier. Background Technology

[0002] Due to the limited amount of concrete used and the dispersed monitoring sections with long distances between them, using cast-in-place concrete for dam safety monitoring is not only time-consuming and labor-intensive but also carries certain safety risks. Furthermore, the monitoring points are easily damaged during on-site cross-operations, leading to reduced monitoring accuracy and unnecessary economic losses. To improve construction efficiency, the dam slope concrete monitoring piers are prefabricated and hoisted to their designed positions after meeting on-site construction conditions. Therefore, clamps must be made during hoisting to ensure the stability of the concrete monitoring piers.

[0003] Currently, there is a lack of specialized equipment for hoisting concrete observation piers for dams. Most existing hoisting clamps are complex in structure, inconvenient to operate, and cannot be well adapted to the shape and size characteristics of the observation piers. During the hoisting process, the observation piers are prone to slippage and damage, which affects the construction progress and the quality of the observation piers. Utility Model Content

Detailed Implementation

[0017] like Figures 1 to 4As shown, this utility model discloses a hoisting device for a dam concrete observation pier. The dam concrete observation pier includes a pier body 13 and a pier column 14. It includes two symmetrically arranged steel clamps for holding the dam concrete observation pier. The clamps include a bracket 7, a base support 8 set at the bottom of the bracket 7 for holding the bottom of the pier body 13, and a crossbeam 15 installed at the top of the bracket 7. One end of the crossbeam 15 is connected to a clamping plate 1 for holding the pier column 14 through a clamping plate connecting seat 12. The crossbeam 15 has multiple lifting holes 4 for connecting lifting equipment and multiple bracket connecting holes 5 located below the lifting holes 4 for connecting the bracket 7 along its length. The bottom of the clamping plate 1 is connected to multiple supporting ribs 3 that abut against the upper surface of the pier body 13. Multiple clamping bolt holes 9 are respectively opened at both ends of the clamping plate 1. The two ends of the two clamping plates 1 are respectively connected by clamping connecting bolts 11. Locking nuts 10 are respectively set on the two outer sides of the clamping plates 1.

[0018] It should be noted that the clamps are made of high-strength steel to ensure sufficient load-bearing capacity and stability during hoisting. The clamping plates are mounted on the crossbeams to clamp the pier column 14. Support ribs 3 are welded to the bottom of the clamping plates, with their bottoms pressed tightly against the upper surface of the pier body 13. This increases stability and prevents slippage during hoisting, preventing swaying or detachment. Multiple lifting holes 4 for connecting lifting equipment and multiple bracket connection holes 5 located below the lifting holes 4 for connecting the brackets 7 are used to adjust the position to accommodate concrete observation piers of different sizes and shapes. The lifting holes are used to connect the hoisting device to the lifting equipment, enabling the hoisting operation of the concrete observation pier.

[0019] In actual fabrication, the entire structure is made of 5mm high-strength steel, ensuring its robustness and stability during hoisting. This significantly reduces safety risks and potential damage to the observation piers caused by instability during hoisting, thereby improving the accuracy and reliability of dam safety monitoring data. Furthermore, the adjustable size of the hoisting device allows it to accommodate concrete observation piers of different specifications, demonstrating its excellent applicability and flexibility. Compared to traditional on-site casting methods, this significantly improves construction efficiency while effectively reducing construction costs.

[0020] In this embodiment, the bracket 7 is connected to the crossbeam 15 by the bracket connecting bolt 6.

[0021] In this embodiment, the clamp connecting seat 12 is welded to the back of the clamp 1, and the clamp connecting seat 12 is connected to the crossbeam 15 by a plurality of clamp connecting bolts 2.

[0022] In this embodiment, the supporting rib 3 is welded to the bottom of the clamping plate 1.

[0023] In this embodiment, one end of the crossbeam 15 is connected to the middle of the clamping plate 1. In this embodiment, the base 8 is a wedge-shaped base.

[0024] In this embodiment, the sidewalls of the two supports 7 abut against the sidewalls of the pier 13.

[0025] When using this utility model, firstly, the clamp 1 is fixed to the crossbeam 15 via the clamp connecting seat 12 and the clamp connecting bolt 2. The dimensions of the concrete observation pier base are determined, the bracket 7 is adjusted to a suitable position and fixed via the bracket connecting bolt 6, the bottom support 8 is inserted into the bottom of the pier body 13, ensuring that the support rib 3 is tightly attached to the upper concrete surface of the pier body 13. The clamp fixing bolt 11 is passed through the clamp bolt hole 9 and the locking nut 10 is tightened. The crane rope is passed through the lifting hole 4, and the lifting equipment slowly lifts the concrete observation pier. The device has advantages such as simple overall structure, convenient operation, high lifting efficiency, and safety and reliability. The lifting operation of the concrete observation pier can greatly improve construction efficiency and reduce construction costs, while ensuring installation accuracy and stability of the concrete observation pier during the lifting process. This greatly reduces the safety risks and potential damage to the observation pier that may be caused by unstable lifting, thereby improving the accuracy and reliability of dam safety monitoring data. In addition, this device is also suitable for the lifting operation of concrete observation piers of different sizes and shapes, and can be widely used in areas with limited terrain conditions, demonstrating its excellent applicability and flexibility. Compared to traditional on-site pouring methods, this significantly improves construction efficiency while effectively reducing construction costs. The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
