吊装固定用锁链的收紧装置

Abstract

本实用新型公开了吊装固定用锁链的收紧装置，包括主体，主体正面设有贯穿上下底面的U型通道，所述U型通道内部中心固定设有直槽口，所述u型通道底部左右两侧壁均通过弹簧组件活动插接设有用于梳理锁链的斜板，所述U型通道上部一侧壁设有空腔，空腔内部转动设有用于收紧固定锁链的收紧齿轮，本实用新型通过设置收紧齿轮与驱动组件，只需转动转轮即可带动收紧齿轮转动，实现对固定锁链的机械收紧，大幅降低了操作强度，单人即可完成收紧作业，借助齿轮传动的特性，能够比较省力的将固定锁链收紧，同时，直槽口与斜板组成的梳理结构能对固定锁链的走向进行约束，避免锁链偏移，确保收紧齿轮能和锁链单环稳定啮合。

Claims

1. A tightening device for a hoisting and fixing chain, comprising a main body (1), a U-shaped channel (2) penetrating the upper and lower bottom surfaces on the front of the main body (1), a hoisting chain (3) connected to the upper end of the main body (1), and a fixing chain (4) connected to one side of the lower end of the main body (1), characterized in that: The U-shaped channel (2) has a straight groove (5) for combing the chain fixed in the center. The other end of the chain (4) passes through the straight groove (5) from the bottom and extends to the top of the U-shaped channel (2). The bottom left and right side walls of the U-shaped channel (2) are movably connected with inclined plates (6) for combing the chain through spring assemblies. The upper side wall of the U-shaped channel (2) has a cavity (7). The cavity (7) is rotatably provided with a tightening gear (8) for tightening the chain (4). A drive assembly for driving the tightening gear (8) to rotate is also provided. The right side wall of the cavity (7) is threadedly connected with a positioning bolt (9) for limiting the rotation of the tightening gear (8).

2. The take-up device for hoisting chains according to claim 1, characterized in that: The spring assembly includes a cavity (10) located on the bottom side wall of the U-shaped channel (2). A guide rod (11) is inserted into the cavity (10). A limiting plate (12) is fixedly provided at one end of the guide rod (11) that extends into the cavity (10). A spring (13) is provided between the limiting plate (12) and the bottom surface of the cavity (10). An inclined plate (6) is fixedly provided at the other end of the guide rod (11).

3. The take-up device for hoisting chains according to claim 1, characterized in that: The drive assembly includes a driven gear (14) fixed on the shaft of the tightening gear (8) and a driving gear (15) rotatably mounted on the front side wall of the cavity (7). The driving gear (15) meshes with the driven gear (14), and a wheel (16) is fixedly mounted on one end of the shaft of the driving gear (15) extending outside the cavity (7).

4. The take-up device for hoisting chains according to claim 1, characterized in that: After the single ring of the fixed chain (4) passes through the straight slot (5), its opening direction is consistent with the entry direction of the tooth end of the tightening gear (8), and the tightening gear (8) meshes with the single ring of the fixed chain (4).

5. The tightening device for the hoisting and fixing chain according to claim 4, characterized in that: The pitch of the single ring of the chain is equal to the pitch of the tooth of the tightening gear (8).
