Description

Technical Field

[0001] This utility model relates to the field of grouting sleeve tightening technology, specifically a grouting sleeve quick tightening device. Background Technology

[0002] A grouting sleeve is an assembly consisting of a specially processed sleeve, matching grouting material, and reinforcing bars. When connecting reinforcing bars, a fast-hardening, non-shrink grouting material is injected, relying on the bonding and interlocking action between the materials to connect the reinforcing bars and the sleeve. Grouting sleeve joints offer advantages such as reliable performance, wide applicability, and easy installation. Grouting sleeve connection technology is suitable for reinforced concrete structures, steel structures, bridges, offshore oil exploration platforms, and near-shore wind power towers. This technology is a new type of steel structure connection method that arose due to engineering needs and technological advancements. Its emergence has overcome the shortcomings of traditional steel structure connections, primarily welding and bolting, and has led to its rapid development and application. Before use, the grouting sleeve needs to be tightened.

[0003] Currently, the tightening of grouting sleeves is usually done manually by workers. Due to the long hours of mechanical work, not only is the tightening force insufficient, increasing the labor intensity of workers, but the tightening efficiency of grouting sleeves is also significantly reduced. Therefore, those skilled in the art have provided a quick-tightening device for grouting sleeves to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a quick-tightening device for grouting sleeves to solve the problems mentioned in the background art.

Detailed Implementation

[0022] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Please see Figures 1-5In this embodiment of the utility model, a grouting sleeve quick-tightening device includes a grouting sleeve tightening component 3 and a grouting sleeve positioning component 4. The grouting sleeve tightening component 3 includes a fixing plate 301, and a grouting sleeve tightening platform 1 is installed on the outer surface of the fixing plate 301. Two support frames 2 are installed on the outer surface of the grouting sleeve tightening platform 1. The grouting sleeve positioning component 4 includes a sliding groove 401, which is opened on the outer surface of the grouting sleeve tightening platform 1. This allows the device to automatically tighten grouting sleeves of different sizes, thereby solving the problem mentioned in the background art that the tightening of grouting sleeves is usually done manually by workers. Due to the long-term mechanical work of workers, not only is the tightening force insufficient, which increases the labor intensity of workers, but also significantly reduces the tightening efficiency of grouting sleeves.

[0025] The outer surface of the fixed plate 301 is inlaid with a first bearing 302. The inner ring of the first bearing 302 is equipped with a rotating rod 303. The outer surface of the rotating rod 303 is engaged with a grouting sleeve tightening head 304. Both the outer surface of the grouting sleeve tightening head 304 and the outer surface of the rotating rod 303 are provided with mounting holes 307. The inner walls of the two mounting holes 307 are threaded with mounting screws 308. The outer surface of the grouting sleeve tightening platform 1 is equipped with a mounting plate 305. The outer surface of the mounting plate 305 is equipped with a drive motor 306. The output end of the drive motor 306 is connected to the rotating rod 303. This not only enables the equipment to automatically tighten the grouting sleeve, but also allows people to easily disassemble and replace the grouting sleeve tightening head 304, so that the equipment can meet the tightening operation of grouting sleeves of different sizes.

[0026] The sliding groove 401 has two sliding blocks 402 internally connected. The outer surfaces of the two sliding blocks 402 are each equipped with a grouting sleeve positioning plate 403. The outer surfaces of the two grouting sleeve positioning plates 403 are each equipped with a grouting sleeve anti-slip pad 404. The inner wall of the sliding groove 401 is inlaid with symmetrical second bearings 405. The inner rings of the two second bearings 405 are jointly equipped with a double-acting screw 406. The outer surfaces of the two sliding blocks 402 are each provided with threaded holes 407. The inner walls of the two sliding blocks 402 are threadedly connected to the double-acting screw 406. The outer surface of the double-acting screw 406 is equipped with a connecting rod 408. The outer surface of the connecting rod 408 is equipped with a circular plate 409. The outer surface of the circular plate 409 is equipped with a ring-shaped handle 410. This not only allows the equipment to fix grouting sleeves of different sizes, but also greatly increases the stability of the grouting sleeve during the tightening process.

[0027] The working principle of this utility model is as follows: First, the grouting sleeve can be placed between two grouting sleeve positioning plates 403 and the sleeve can be inserted into the grouting sleeve tightening head 304. Then, the double-acting screw 406 can be rotated using the handle 410. The double-acting screw 406 can drive the sliding block 402 and the grouting sleeve positioning plate 403 to move and fix the grouting sleeve. Then, the drive motor 306 can be started. The drive motor 306 can drive the rotating rod 303 and the grouting sleeve tightening head 304 to rotate and automatically tighten the grouting sleeve. The anti-slip pad 404 of the grouting sleeve can prevent the grouting sleeve from slipping during the tightening process.
