[0021] The utility model provides a pipeline laying device for water conservancy and hydropower engineering construction, Figures 1 to 3 Including bottom plate 1, four corner places of bottom plate 1 bottom setting roller 11, two groups of supports 2 corresponding positions are hinged on the top surface of bottom plate 1, two fixed shafts 3 that each group support 2 is away from bottom plate 1 one end are penetrated in proper order respectively and the roller 4 that is set above bottom plate 1 and two ends are fixedly connected with fixed shaft 3, fixed shaft 3 is rotatably connected with support 2, the fixed wheel 41 with sawtooth edge is fixedly connected in roller 4 two ends respectively, the fixed ring 31 is sleeved in the fixed shaft 3 near roller 4 one end, the fixed ring 31 is fixedly connected on support 2, the protruding plate 32 is set on the fixed ring 31, the sliding groove 33 is horizontally set on the protruding plate 32, the sliding rod 34 is set on the protruding plate 32, the sliding rod 34 two ends are penetrated protruding plate 32 and are slidably connected on protruding plate 32 along sliding groove 33, the first elastic member 35 is set in sliding groove 33 in protruding plate 32, the first elastic member 35 two ends are fixedly connected in sliding groove 33 inner wall and sliding rod 34.

[0022] When working normally, each group of supports 2 fixes the position of the fixed shaft 3 through two supports 2 in a triangular structure, the roller 4 is fixedly connected with the fixed shaft 3 and rotates together on the support 2, the roller 4 drives the fixed ring 31 to rotate, the protruding plate 32 on the fixed shaft 3 remains stationary due to the fixed connection with the support 2, the pipeline is separated from the laying device and the laying is completed through movement, when the route deviates and is wrong, the sliding rod 34 is moved, the sliding rod 34 is compressed at both ends by the first elastic member 35 and is clamped on the sawtooth at the edge of the fixed wheel 41, a pin or a small stick can be inserted into the sliding groove 33 on the side of the sliding rod 34 away from the first elastic member 35 to keep the sliding rod 34 stationary, at this time, the fixed wheel 41 and the roller 4 cannot rotate, and the position of the pipeline that has been laid can be changed or the pipeline can be tightened to adjust the laying direction of the pipeline by continuing to move the laying device.

[0023] Further, referring to Figure 2 、 Figures 4 to 5 , the bottom plate 1 is provided with a pulling mechanism 5 for moving the laying device, the pulling mechanism 5 includes a fixed seat 51 fixedly connected to the top surface of the bottom plate 1 at a position corresponding to one side of the roller 4, a rotating shaft 52 penetrating through the fixed seat 51 in the direction of the roller 4, a pull rod 53 fixedly connected at both ends of the rotating shaft 52, a handrail 54 fixedly connected at one end of the pull rod 53 away from the rotating shaft 52, an arc-shaped groove 55 opened in the fixed seat 51 with the rotating shaft 52 as the center, a pressing rod 56 movably connected to the fixed seat 51 along the arc-shaped groove 55, and a second elastic member 57 arranged in the arc-shaped groove 55, both ends of the pressing rod 56 are fixedly connected with the two pull rods 53 respectively, and both ends of the second elastic member 57 are fixedly connected with the pressing rod 56 and the inner wall of the arc-shaped groove 55 respectively.

[0024] In a natural state, the second elastic member 57 presses the pressing rod 56, the pressing rod 56 drives the pull rod 53 to rotate around the rotating shaft 52, the pull rod 53 drives the handrail 54 to move upwards until the pull rod 53 and the handrail 54 are collected within the range of the bottom plate 1, thereby saving the occupied space, when the laying device is pulled, the handrail 54 is pressed downwards, the handrail 54 drives the pull rod 53, the pull rod 53 drives the pressing rod 56 to compress the second elastic member 57 and move in the arc-shaped groove 55 until the handrail 54 and the pull rod 53 move to a position outside the bottom plate 1 suitable for the force of the staff.

[0025] It is worth noting that, referring to Figures 2 to 3The protruding plate 32 is arranged towards the pull rod 53, and the first elastic member 35 pushes the sliding rod 34 to be separated from the fixed wheel 41 in operation, so that the roller 4 rotates normally. When the laying device is stopped for laying, the handrail 54 is loosened, the pull rod 53 is rotated by the pressure rod 56 under the action of the second elastic member 57, until the pull rod 53 contacts with the sliding rod 34 and pushes the sliding rod 34 to compress the first elastic member 35, and the sliding rod 34 clamps the fixed wheel 41, so that the roller 4 cannot rotate. The pull rod 53 abutting against the sliding rod 34 can fix the roller 4 when the laying device is stopped, and the pipeline is tightened, so that the roller 4 cannot rotate to cause the pipeline to be separated from the roller and scattered on the laying device.

The sliding seat 62 is threadedly connected with a fixing bolt 66 for fixing the relative position of the sliding seat 62 and the angle plate 61. Since the pipeline can be wound on any part within the range of the roller 4, the position of the pipeline when separated from the roller 4 is uncertain. The sliding seat 62 is fixed at a suitable position by using the fixing bolt 66, and then the pipeline is passed through between the limiting rod 63 or the sleeve 64, so that the position of the pipeline separated from the laying device is determined, and the laying position of the pipeline is determined, so that the route of the pipeline is not deviated.

[0027] Further, referring to Figures 1 to 2 The end of the limiting rod 63 close to the connecting plate 65 is provided with a thread, and the inner walls of both ends of the sleeve 64 are provided with threads. The thread on the limiting rod 63 is matched with the thread on the sleeve 64.
