Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3 The utility model discloses an auxiliary positioning tool for guardrail construction, including a base plate 1 and a positioning assembly 2, the positioning assembly 2 is arranged on the base plate 1, the positioning assembly 2 includes a supporting cross bar 21, an adjusting rod 23 and a screw rod 24 located on both sides of the adjusting rod 23 are rotatably arranged inside the supporting cross bar 21, two nut sleeves 26 are movably sleeved on the supporting cross bar 21 and are respectively located on both sides of the adjusting rod 23, a nut seat with one end extending into the interior of the supporting cross bar 21 and threadedly sleeved with the screw rod 24 is arranged inside the nut sleeve 26, a disc 261 is fixedly arranged on the top of the nut sleeve 26, a supporting arm 27 is clamped on the top of the disc 261, a clamping seat 28 is arranged on the top of the end of the supporting arm 27 away from the disc 261, and at least one clamping screw 281 is arranged on both sides of the clamping seat 28.

[0023] Specifically, the top of the disc 261 and the bottom of one end of the support arm 27 are provided with docking grooves 29 that are movably engaged with each other. When the angle of the support arm 27 is required, the end of the support arm 27 with the docking groove 29 is vertically lifted to separate the docking groove 29 on the support arm 27 from the docking groove 29 on the disc 261. After rotating the support arm 27, the support arm 27 can be reinserted into the disc 261 through the docking groove 29. When the installation environment is complicated and it is inconvenient to hoist the base plate 1, the lifting direction can be adjusted by rotating the support arm 27.

[0024] Specifically, one end of the clamping screw 281 extends to the interior of the clamping seat 28 and is provided with a hinged seat through a bearing. The end of the hinged seat away from the clamping screw 281 is hinged with a clamping plate 282. Multiple clamping screws 281 cooperate with the clamping plate 282 that can be rotated and adjusted in angle, and can be adapted to clamp guardrail cross bars of different shapes, such as square, round, curved, etc. The clamping process is more stable and the operation is more convenient. The height of the supporting cross bar 21 is adjusted so that the clamping seat 28 lifts the guardrail cross bar, and the clamping screw 281 is rotated to drive the clamping plate 282 to clamp the guardrail cross bar.

[0025] Specifically, a fixed seat 11 is provided on the top of the base plate 1, and a support rod 22 whose bottom end is movably inserted into the fixed seat 11 is provided at the bottom of the support cross bar 21. A fixed screw barrel 12 is fixedly provided inside the fixed seat 11. The bottom end of the adjusting rod 23 passes through the support rod 22 and is provided with a threaded section threadedly engaged with the fixed screw barrel 12. The adjusting rod 23 is rotatably provided inside the column and the support cross bar 21. When the height of the support cross bar 21 needs to be adjusted, the height of the support cross bar 21 can be adjusted by rotating the adjusting rod 23 by hand wheel 231.

[0026] Specifically, hand wheels 14 are movably provided at the top of the four corners of the base plate 1, and a gripping screw 15 whose bottom end is screwed into the base plate 1 is provided at the bottom of the hand wheel 14. A plurality of movable wheels 13 are provided at the bottom of the base plate 1, and the base plate 1 can be moved by the movable wheels 13, which makes the operation on the construction site more convenient. When it is necessary to lift and support the guardrail cross bar, the gripping screw 15 is rotated by the hand wheel 14 to penetrate the ground, thereby avoiding the movement of the movable wheel 13 and ensuring the stability of the base plate 1. The level of the base plate 1 can also be adjusted according to the uneven ground through the gripping screw 15.

[0027] Specifically, the top of the adjusting rod 23 extends to the top of the supporting cross bar 21 and is provided with a second hand wheel 231. By rotating the screw rod 24 through the second hand wheel 231, the nut sleeve 26 can be driven to drive the supporting arm 27 and the clamping seat 28 to move. When in use, when rotating the first guardrail cross bar, two auxiliary positioning tools for guardrail construction can be used to hold up the two ends of the guardrail cross bar, and the mobile base plate 1 fixes the guardrail cross bar to the guardrail column with bolts. When the first guardrail cross bar is installed, the auxiliary positioning tool for guardrail construction is moved to the second guardrail cross bar installation position, and the auxiliary positioning tool for guardrail construction is used to hold up the second guardrail cross bar. The two ends of the rod are connected, and the second guardrail cross bar is moved to dock with the first guardrail cross bar. Each supporting cross bar 21 has two independently driven clamping seats 28. After starting one clamping seat 28 to connect with the second guardrail cross bar, the second clamping seat 28 is connected to the first guardrail cross bar that has been fixed. The user rotates the screw rod 24 through the handwheel three 241 to drive the clamping seat 28 holding the second guardrail cross bar to move, so that one end of the second guardrail cross bar is docked with one end of the first guardrail cross bar. During the docking operation, it is necessary to first rotate the handwheel one 14 to drive the gripping screw 15 to contact the ground, which ensures the stability of the base plate 1 and avoids shaking during the docking operation.

[0028] Specifically, one end of the screw rod 24 away from the adjusting rod 23 extends to one side of the supporting cross bar 21 and is provided with a hand wheel three 241. The two nut sleeves 26 and the supporting arm 27 are independently driven by the two screw rods 24, which facilitates the user to connect one guardrail cross bar with another guardrail cross bar.

[0029] Specifically, both ends of the bottom of the support crossbar 21 are provided with diagonal braces 25 , and the bottom ends of the two diagonal braces 25 are respectively fixedly connected to the two sides of the support rod 22 . The provision of the diagonal braces 25 ensures the stability of the support crossbar 21 .

[0030] To sum up, the auxiliary positioning tooling for guardrail construction can hoist the guardrail cross bar onto the clamping seat 28 through hoisting construction, and the guardrail cross bar can be moved through the base plate 1 for installation, which will not occupy the construction machinery for a long time, making it convenient for the construction machinery to carry out other guardrail hoisting operations, greatly improving the installation efficiency and reducing the installation cost. The adjustable height support cross bar 21 can adapt to the installation requirements of guardrail cross bars of different heights. Through the two clamping seats 28, it is convenient to connect the two guardrail cross bars, and the installation process is more stable and quick.
