[0027] The utility model provides a long spiral pressure irrigation process reinforcement cage elevation auxiliary control device.

[0028] Embodiment one:

[0029] As Figures 1-2 It includes stand 1 and support arm 2, and the bottom of stand 1 is fixedly connected with base 3, and the bottom of base 3 is fixedly connected with positioning column 31, and the bottom end of positioning column 31 is a sharp head, and by stepping on base 3, positioning column 31 is inserted into the ground through the sharp head, so that stable supporting force can be provided for stand 1, and the top of stand 1 is hingedly connected with limiting rod 4, and recess 41 is formed in the top of limiting rod 4, and cylindrical bubble 42 is fixedly installed in recess 41, and one side of stand 1 is fixedly connected with support plate 43, and adjusting bolt 44 is screw-connected in support plate 43, and limiting rod 4 is rotated, and the bottom of limiting rod 4 is overlapped on the top of adjusting bolt 44, and by rotating adjusting bolt 44 in support plate 43, limiting rod 4 can be rotated, and the height of one end of limiting rod 4 is adjusted, and then whether the straight line where limiting rod 4 is located is horizontal or not can be judged by cylindrical bubble 42.

[0030] The bottom of support arm 2 is fixedly installed with bearing 21, and support arm 2 is rotatably connected with sleeve pipe 22 through bearing 21, and the outer surface of sleeve pipe 22 is screw-connected with fixed bolt 23, and fixed bolt 23 penetrates into the inside of sleeve pipe 22, and sleeve pipe 22 is sleeved on the top end of one main reinforcement of reinforcement cage, and then by rotating fixed bolt 23, the top of fixed bolt 23 abuts against the main reinforcement of reinforcement cage, so that sleeve pipe 22 can be fixed on the outer surface of the main reinforcement of reinforcement cage, and the top of support arm 2 is fixedly installed with connecting arm 24.

[0031] Preferably, as Figure 1 The side surface of stand 1 is provided with receiving groove 5, and when not in use, limiting rod 4 can be rotated into receiving groove 5, so as to avoid the problem that limiting rod 4 is bumped in the process of carrying and is bent, and one side of stand 1 is screw-connected with positioning bolt 51, and after limiting rod 4 is rotated into receiving groove 5, positioning bolt 51 is rotated, so that the surface of limiting rod 4 is abutted against, limiting rod 4 is positioned, and the problem that limiting rod 4 is rotated out in the process of carrying can be avoided.

[0032] Preferably, as Figure 2As shown, a hinge sleeve 25 is fixedly connected to the top of the support arm 2, and the connecting arm 24 is hinged inside the hinge sleeve 25. When the support arm 2 descends with the steel cage, the connecting arm 24 presses against the top of the limiting rod 4. If the steel cage continues to descend, the connecting arm 24 will rotate inside the hinge sleeve 25 to prevent the connecting arm 24 from pressing hard on the limiting rod 4, which could cause the connecting arm 24 or the limiting rod 4 to deform or bend.

[0033] The working principle of this embodiment is as follows: The column 1 and support arm 2 are customized according to the elevation of the top of the steel cage. When in use, the column 1 is fixed to one side of the pile hole through the base 3 and the positioning column 31 at the bottom. Then, the limiting rod 4 is rotated so that it overlaps the top of the adjusting bolt 44. The height of one end of the limiting rod 4 is adjusted by adjusting the adjusting bolt 44. By observing the cylindrical spirit level 42, the limiting rod 4 is adjusted to be horizontal.

[0034] The support arm 2 is fixed to the top of one of the main bars of the steel cage by the sleeve 22 and the fixing bolt 23. Then, the steel cage is lowered into the pile hole by the hoisting equipment. When the connecting arm 24 is lowered to a certain height and is about to approach the height of the limit rod 4, the support arm 2 is rotated so that the connecting arm 24 is directly above the limit rod 4. Then the steel cage continues to be lowered. When the connecting arm 24 contacts the limit rod 4, the descent stops, thereby achieving the purpose of strictly controlling the elevation of the steel cage.

[0035] Example 2:

[0036] like Figure 3 As shown, based on Embodiment 1, the column 1 includes a sleeve 11 and a vertical rod 12. A piston rod 121 is fixedly connected to the bottom end of the vertical rod 12. The piston rod 121 is slidably inserted into the inside of the sleeve 11. By sliding the piston rod 121 up and down inside the sleeve 11, the overall height of the column 1 can be adjusted. A limit bolt 111 is threadedly connected to one side of the sleeve 11. By tightening the limit bolt 111, it is pressed against the surface of the piston rod 121, thereby fixing the piston rod 121 and achieving the purpose of fixing the height of the column 1. An anti-slip pad 122 is embedded in one side of the piston rod 121. The anti-slip pad 122 is elastic. By tightening the limit bolt 111, the end of the limit bolt 111 can be inserted into the inside of the anti-slip pad 122, thereby improving the firmness of the limit bolt 111 in fixing the piston rod 121.

[0037] The working principle of this embodiment is as follows: In use, according to the elevation of the top of the steel cage, after fixing the column 1, the height of the column 1 can be adjusted by sliding the piston rod 121 in the sleeve 11, thereby achieving the purpose of adjusting the height of the limit rod 4. Therefore, it can be used for steel cages with different elevations without the need to customize the column 1, thus having universality.

[0038] Example 3:

[0039] As Figure 4 shown, on the basis of example two, the outer surface of the sleeve 11 is fixedly connected with the fixed plate 6, the top of the fixed plate 6 is provided with the laser line projector 61, the laser line projector 61 is the prior art, and the use method and structural principle thereof are the technology well known to the person skilled in the art, the laser line projector 61 is leveled before use, can project the plumb line, before the reinforcement cage enters the pile hole, by observing whether the plumb line and the main reinforcement of the reinforcement cage coincide, whether the reinforcement cage is vertical can be judged, the top of the fixed plate 6 is provided with a plurality of positioning grooves 62, three feet at the bottom of the laser line projector 61 are used for inserting into the positioning grooves 62, the laser line projector 61 can be simply fixed, and the problem of the laser line projector 61 falling off is avoided.

[0040] When the reinforcement cage is inclined to the direction of the laser line projector 61, the plumb line projected by the laser line projector 61 can still coincide with one of the main reinforcements of the reinforcement cage, thus possibly leading to the misjudgment, in order to solve the problem, preferably, the number of the laser line projectors 61 is two, by making the two laser line projectors 61 project two plumb lines, two plumb lines coincide with one or two main reinforcements of the reinforcement cage, thus when the reinforcement cage is inclined, one plumb line will not coincide with the main reinforcement of the reinforcement cage, thus the problem of misjudgment can be avoided.

[0041] The working principle of the embodiment is as follows: in use, after the reinforcement cage is vertically hoisted, the laser line projector 61 is leveled, then the plumb line is projected on the main reinforcement of the reinforcement cage, whether the plumb line and the main reinforcement coincide can be observed to judge whether the reinforcement cage is vertical, thus the reinforcement cage is convenient to adjust.
