[0002] In the construction of secondary water supply pipelines in urban pipe networks, the layout direction of pipelines often turns left, turns right or changes direction vertically upward according to needs. Therefore, in pipeline construction, elbow joints are used to connect two pipelines at the turning point, and the connection between the elbow joint and the pipeline is often carried out by welding or bonding. During the construction process, in order to ensure welding or bonding operations, the elbow joint needs to be kept in a fixed state, but there is a lack of corresponding tooling equipment on site. For the connection of pipelines with horizontal right-angle changes (turning left or right), a support plate is usually used to simply support the elbow joint to ensure the fixed state of the elbow joint when connecting with the pipeline; for the connection of pipelines with vertical upward changes, the connection of the elbow joint requires two people to complete. One person controls the position of the elbow joint to ensure that one open end of the elbow joint is vertically upward and is aligned with the corresponding pipeline, and the other person performs the connection operation, which brings great inconvenience to the construction.

[0021] The present utility model will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0022] An installation tool for elbow joints in secondary water supply construction, as Figure 1 、 2 shown in and Figure 3, includes a flat plate 1. Universal wheels are provided at the bottom of the flat plate 1, and the universal wheels are provided with a braking structure (not shown in the figure). A push rod 8 is provided on the flat plate 1 to push the flat plate 1 to move. A base 2 and a vertical plate 7 are arranged on the flat plate 1, and the vertical plate 7 is located on one side of the base 2.

[0023] The base 2 is a U-shaped block structure with an opening facing downwards, which includes a top plate and two side plates arranged opposite to each other. The two side plates are fixedly installed on the flat plate 1. A stud 11 is threadedly connected to the top plate of the base 2. A handwheel 9 is provided at the bottom end of the stud 11, and the upper end of the stud 11 is rotatably connected to a support block 10. For example, the stud 11 is connected to the support block 10 through a bearing. At this time, the support block 10 is supported by the stud 11, and the stud 11 can rotate relative to the support block 10. When the stud 11 rotates, the support block 10 can be driven to move up and down. Guide posts 3 are respectively provided at the left and right ends of the bottom surface of the support block 10 facing downwards. The top plate of the base 2 is provided with guide holes corresponding to the guide posts 3. The guide posts 3 pass through the corresponding guide holes, and the guide posts 3 and the guide holes form a guiding structure to ensure the up and down movement of the support block 10, ensure the linearity of the movement of the support block 10, and at the same time limit the rotational freedom of the support block 10, so that the support block 10 can only move in the vertical direction and cannot rotate with the stud 11. A V-shaped iron 4 is provided on the support block 10, and the center line of the V-shaped iron 4 is perpendicular to the vertical plate 7. The V-shaped iron 4 is used to support the elbow joint. Bending pipe fixing structures are respectively provided at the top end and the left and right ends of the vertical plate 7.

[0024] The structure of the vertical plate 7 is as Figure 4 shown. The bending pipe fixing structure at the top end of the vertical plate 7 includes a horizontal strip hole 71 opened at the top of the vertical plate 7. The bending pipe fixing structures at the left and right ends of the vertical plate 7 include vertical strip holes 72 opened at the left and right ends of the vertical plate. U-shaped clamps 6 for fixing the bending pipe are respectively arranged in the horizontal strip hole 71 and the vertical strip holes 72.

[0025] The operation process of the present utility model is as follows: Place the elbow joint 5 on the V-shaped iron 4. At this time, the V-shaped iron 4 supports the pipe diameter part corresponding to one opening end of the elbow joint 5. Adjust the position of the flat plate 1 and the position of the V-shaped iron 4 so that this opening end is directly opposite to the port of the horizontal pipe to be connected. Rotate the elbow joint 5 according to the position of the other port of the pipe to be connected, that is, make the other port of the elbow joint 5 face upwards or leftwards or rightwards according to the construction needs. In this embodiment, Figures 1 - 3The following shows the construction of a vertically upward pipe direction change. The other port of the elbow joint 5 is vertically upward. The U-shaped clamp 6 is used to fix the pipe diameter position of the elbow joint corresponding to this other port to the vertical plate 7, so that the position of the elbow joint 5 is fixed, and the positions of its two ports are fixed, facilitating the connection construction with the pipe. By the same token, when the pipe changes direction to the left or right, after the V-shaped iron 4 supports one end of the pipe joint 5, the other port of the pipe joint 5 is adjusted to be in a horizontal state, and then it is fixed to the corresponding vertical strip hole 72 using the U-shaped clamp 6 to achieve the fixation of the pipe joint 5.

[0026] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
