Description

Technical Field

[0001] This utility model relates to the field of prefabricated sluice gate construction technology, specifically to a concrete foundation marking and positioning mechanism. Background Technology

[0002] During the construction of prefabricated sluice gates, the prefabricated sluice gate components are usually transported to the construction site and then lifted by a crane and placed on a concrete foundation. The concrete foundation is usually poured in three sections on the foundation, and the spacing between adjacent concrete foundations is equal after pouring. After confirming that the dimensions and flatness of the foundation layer meet the requirements, the designers delineate the central axis of the sluice gate based on the channel centerline and the foundation dimensions of each component of the sluice gate. This ensures that the sluice gate components can be correctly installed from the hook onto the concrete foundation layer, reducing installation errors. However, due to the long and discontinuous spacing of the concrete foundation layer, the existing marking mechanism has several problems. First, the lack of a positioning mechanism between the marking mechanism and the foundation layer leads to offset during the marking process. Second, since the foundation layer is in three sections, the marking usually needs to be done in three sections, and the lines of adjacent sections cannot be guaranteed to be on the same straight line, affecting the subsequent installation accuracy of the prefabricated sluice gate.

The adjusting shaft 12 passes through the interior of the two sets of slide rods 13. The hand lever 11 is provided with a receiving hole 112 for accommodating the adjusting shaft 12.

[0018] Furthermore, such as Figure 4 As shown, the adjusting shaft 12 has a threaded section 123 on its outer side and in the area inside the retraction groove 111, and the corresponding threaded sections 123 in the two sets of retraction grooves 111 have opposite helical directions; The slide bar 13 has a threaded hole 131 inside that is threadedly connected to the threaded section 123, which is used to drive the two sets of clamping blocks 14 to move in opposite directions; One end of the adjusting shaft 12 and inside the hand handle 11 is fixedly connected to a limiting plate 122 for limiting the adjusting shaft 12, and the limiting plate 122 is rotatably connected to the hand handle 11. A knob 121 is fixedly connected to one end of the adjusting shaft 12 relative to the limiting disk 122 for rotating and adjusting the adjusting shaft 12.

[0019] As an improvement, such as Figure 2 , Figure 5 As shown, the first side extension mechanism 22 includes: A first side guide rod 222 has a first rotating shaft 2221 fixedly connected to one side near its end. A first limiting shaft 2222 is fixedly connected to one end of the first side guide rod 222 and inside the hand handle 11. The first limiting shaft 2222 is rotatably connected to the hand handle 11. A second limiting hole 114 is provided inside the hand handle 11 and outside the first limiting shaft 2222 for accommodating and limiting the first limiting shaft 2222. The pad 221 is fixedly connected to the upper end of the middle guide rod 21 and is used to support the bottom of the first side guide rod 222; The first side support rod is fixedly connected to one end of the hand handle 11. The first side support rod is L-shaped with its upper end face at the same level as the upper end face of the pad 221, and is used to cooperate with the pad 221 to support the first side guide rod 222.

[0020] Furthermore, such as Figure 2 , Figure 6 As shown, the second side extension mechanism 23 includes: The second side guide rod 231 has a second rotating shaft 2311 fixedly connected to one side near the end.

The second support rod 232 is fixedly connected to one end of the hand handle 11 relative to the first support rod 223, and is used to cooperate with the middle guide rod 21 to support the lower end of the second side guide rod 231.

[0021] Furthermore, the central guide rod 21, the first side guide rod 222, and the second side guide rod 231 are located on the same horizontal plane relative to one side of the handheld lever 11, which is used to guide the marking work.

[0022] It should be noted that: in the specific implementation process of this utility model, if... Figure 1-4 As shown, when marking the upper end of the three sets of casting pads 101, the hand lever 11 is placed on the upper end of the casting pad 101 of the middle part, and the two sets of clamping blocks 14 are located on both sides of the casting pad 101. The knob 121 is turned, and the knob 121 drives the adjusting shaft 12 to rotate in the hand lever 11. The adjusting shaft 12 drives the two sets of sliding rods 13 to move relative to each other along the retraction groove 111 through the threaded section 123 and the threaded hole 131. The sliding rods 13 drive the clamping blocks 14 to clamp on both sides of the middle casting pad 101, so that the hand lever 11 is positioned to avoid the phenomenon of line deviation during subsequent marking. like Figure 1-6 As shown, subsequently, the first side guide rod 222, located at the upper end of the second side guide rod 231, is rotated 180° relative to the second side guide rod 231 under the action of the first rotating shaft 2221, so that the lower end of the first side guide rod 222 is placed on the casting pad 101 on one side of the intermediate casting pad 101. Then, the second side guide rod 231, located at the upper end of the middle guide rod 21, is rotated 180° relative to the middle guide rod 21 under the action of the second rotating shaft 2311, so that the second side guide rod 232 is rotated 180° relative to the middle guide rod 21. The lower end of 1 is placed on the other side of the middle casting pad 101. At this time, the second side guide rod 231, the middle guide rod 21, and the first side guide rod 222 form a guide surface on the three intermittent casting pads 101. By using a scribing pen to scribing lines on the casting pad 101 along the second side guide rod 231, the middle guide rod 21, and the first side guide rod 222 in sequence, the scribing work can be completed, and the effect of ensuring that the lines of two adjacent segments are on the same straight line can be achieved.
