The telescopic assembly 16 may be fixed to one side of the longitudinal rod 14 by a fixed rope 22 and a hoist 21 without rotating relative to the longitudinal rod 14 through the second pivot assembly 15. When the longitudinal rod 14 rotates relative to the transverse rod 12 through the first pivot assembly 13 and is vertically installed outside the bridge, the user can change the length of the fixed rope 22 by operating the winch 21, so that the telescopic assembly 16 can The second pivot assembly 15 slowly rotates relative to the longitudinal rod 14 and changes from the state of FIG. 4 to the state of FIG. 5.

One end of the auxiliary rope body 171 is fixed to the longitudinal rod 14, and the other end of the auxiliary rope body 171 is fixed to the end of the fixing rod 161 away from the second pivot assembly 15. Of course, the longitudinal rod 14 and the fixed rod 161 may have a structure for interconnecting with the auxiliary rope body 171, such as a hook and loop, etc., which is not limited herein.

Through the arrangement of the auxiliary rope body 171, the deformation amount of the fixed rod 161 relative to the longitudinal rod 14 can be effectively limited, so that the movable rod 162 can smoothly move relative to the fixed rod 161. When the lengths of the fixed rod 161 and the movable rod 162 are relatively long, for example, when the lengths of the fixed rod 161 and the movable rod 162 exceed 2 meters, respectively, the fixed rod 161 is not provided with the auxiliary rope body 171 Next, the end of the fixed rod 161 away from the longitudinal rod 14 will easily hang down, which may cause the movable rod 162 to be unable to move relative to the fixed rod 161. Therefore, through the installation of the auxiliary rope body 171, the deformation of the fixing rod 161 relative to the longitudinal rod 14 can be greatly reduced. Of course, in a better embodiment, the auxiliary support assembly 17 may further include a tension adjusting unit 172, which can adjust the tension of the auxiliary rope body 171 correspondingly, and the user can adjust the tension according to the needs The distance the fixed rod 161 moves) correspondingly changes the tension of the auxiliary rope body 171. In the embodiment where the length of the fixing rod 161 is greater than 2 meters, the included angle θ of the auxiliary rope body 171 and the central axis of the fixing rod 161 is between 5 and 10 degrees, which will achieve a better auxiliary supporting effect.

In addition, when the movable bar 162 moves to the maximum movable position relative to the fixed bar 161, at least one tenth of the section of the movable bar 162 is located in the fixed bar 161, so that the movable bar 162 can be greatly reduced relative to the fixed bar The amount of deformation of 161. In more detail, in the embodiment in which the movable rod 162 and the fixed rod 161 are connected by a sleeve, one end of the movable rod 162 is connected to the fixed rod 161, and the other end of the movable rod 162 is a free end. The free end of the movable rod 162 is also provided with a detection device 18. Therefore, when the movable rod 162 moves to the maximum movable range relative to the fixed rod 161, if the section of the movable rod 162 in the fixed rod 161 is too small, the movable rod 162 The connection between the 162 and the fixed rod 161 will easily cause the problem of stress concentration, which may lead to the problem of the destruction of the related structure where the movable rod 162 and the fixed rod 161 are connected. Therefore, in the embodiment in which the movable rod 162 and the fixed rod 161 are connected to each other in a sleeve manner, by limiting the maximum movable range of the movable rod 162 relative to the fixed rod 161 (ie, the movable rod 162 moves relative to the fixed rod 161 At the maximum movable position, at least one tenth of the movable rod 162 is located in the fixed rod 161), which will greatly damage the above-mentioned structural damage at the connection between the low movable rod 162 and the fixed rod 161.

As described above, in the embodiment in which the movable rod 162 and the fixed rod 161 are connected to each other by a sleeve, the above-mentioned design of the auxiliary support assembly 17 and the restriction of the movable rod 162 relative to the fixed rod 161 will greatly improve the telescopic assembly 16 Overall structural stability and service life.

In addition, it should be noted that in special applications, one end of the auxiliary rope body 171 may not be fixed to the fixed rod 161, but fixed to the end of the movable rod 162 away from the fixed rod 161. In this embodiment, when When the movable rod 162 moves to the maximum movable position relative to the fixed rod 161, the triangle formed by the auxiliary rope body 171, the longitudinal rod 14, the fixed rod 161, and the movable rod 162 will restrict the movable rod 162 relative to the bottom surface of the bridge B B2 distance. In other words, the embodiment where the end of the auxiliary rope body 171 is fixed to the end of the movable rod 162 away from the longitudinal rod 14 will not be applicable to the situation where the height of the bottom surface B2 of the bridge B and the water surface is relatively low; otherwise, the auxiliary rope body The embodiment in which one end of 171 is fixed to the fixing rod 161 is applicable to the situation where the height of the bottom surface B2 of the bridge B and the water surface is relatively low.

In the embodiment where the movable rod 162 and the fixed rod 161 are connected to each other in a sleeve manner, the movable rod 162 and the fixed rod 161 may be, for example, square tubes, round tubes, or triangular tubes, wherein the movable rod 162 and the fixed rod 161 are square The sleeves are connected to each other, and the movable rod 162 and the fixed rod 161 can have relatively better connection support strength.
