[0026] The auxiliary tube placing assembly 4 comprises a first stabilizing plate 41, a supporting plate 42, a first bearing 43 and a connecting shaft 44. The upper surface of the first stabilizing plate 41 is fixedly connected with two supporting plates 42 symmetrically along the center. The top end of the side wall of the supporting plate 42 is inlaid with the first bearing 43. The interior of the first bearing 43 is fixedly sleeved with the connecting shaft 44.

[0027] The lower surface of the first stabilizing plate 41 is connected to the top of the fire hydrant 1, the surface of the connecting shaft 44 is fixedly sleeved with a retracting tube 45, one end of the connecting shaft 44 is fixedly connected with a first limiting rod 46, the surface of the first limiting rod 46 is fixedly sleeved with a first driving wheel 47, the surface of the first driving wheel 47 is connected with a transmission belt 48, the bottom end of the side wall of the support plate 42 is detachably mounted with a forward and reverse motor 49, one end of the forward and reverse motor 49 is fixedly connected with a second limiting rod 410, the surface of the second limiting rod 410 is fixedly sleeved with a second driving wheel 411, the surface of the second driving wheel 411 is in contact with one side of the transmission belt 48, and the sliding limiting assembly 5 includes a second stabilizing plate 51, a first limiting frame 52 and a second bearing 53. A first limiting frame 52 is fixedly connected to the middle of the upper surface of the second stabilizing plate 51, and two second bearings 53 are symmetrically inlaid and installed on the surface of the first limiting frame 52 along the center. The lower surface of the second stabilizing plate 51 is connected to the bottom end of the inside of the fire hydrant 1, and the inside of the second bearing 53 is fixedly sleeved with a first limiting wheel 54. The upper surface of the first limiting frame 52 is provided with four grooves in a rectangular array, and the bottom end of the inside of the groove is fixedly connected to a telescopic rod 55, and the surface of the telescopic rod 55 is fixedly sleeved with a return spring 56, and the top of the return spring 56 is fixedly connected to a second limiting frame 57, and the surface of the second limiting frame 57 is symmetrically inlaid and installed with two third bearings 58 along the center, and the inside of the third bearing 58 is fixedly sleeved with a second limiting wheel 59.

[0028] Benefits: The arrangement of the first limiting wheel 54 and the second limiting wheel 59 is conducive to limiting the position of the water pipe, thereby avoiding the phenomenon of the position of the water pipe being offset.

[0029] The working process of the utility model is as follows:

[0030] When the auxiliary pipe placing device is in use, in order to reduce the cost of use, a sliding limit assembly 5 is provided. Before the auxiliary pipe placing assembly 4 works, the second limit frame 57 inside the sliding limit assembly 5 is first stretched outward, and then the second limit frame 57 will drive the telescopic rod 55 and the return spring 56 to move. After moving to a certain distance, one end of the water pipe is passed through the center of the first limit wheel 54 and the second limit wheel 59, and then the second limit frame 57 is released. At this time, the return spring 56 will drive the second limit frame 57 to return to its original position, so that the first limit wheel 54 and the second limit wheel 59 will limit the passing water pipe. Because the first limit wheel 54 is connected to the first limit frame 52 through the second bearing 53, and the second limit wheel 59 is connected to the second limit frame 57 through the third bearing 58, sliding friction can be used instead of static friction to reduce the friction force applied to the water pipe when it is pulled, thereby saving costs.

[0031] In the above scheme, in order to reduce the workload of the staff when the auxiliary pipe release device is in use, a forward and reverse motor 49, a second driving wheel 411, a transmission belt 48 and a first driving wheel 47 are provided. When the water pipe needs to be reeled in, the water pipe passing through the sliding limit assembly 5 is first connected to the surface of the retracting cylinder 45, and then the forward and reverse motor 49 is started to rotate, and then the forward and reverse motor 49 will drive the second limit rod 410 and the second driving wheel 411 to rotate. Because the first driving wheel 47 is connected to the second driving wheel 411 through the transmission belt 48, and the retracting cylinder 45 is connected to the first driving wheel 47 through the connecting bearing 44, the first bearing 43 and the first limit rod 46, the rotation of the second driving wheel 411 can drive the retracting cylinder 45 to rotate, so that the water pipe is reeled in. Because the forward and reverse motor 49 has the function of automatic rotation, it can replace the staff to reel in the water pipe, thereby reducing the workload of the staff.
