[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0024] Embodiment 1:

[0025] See also Figure 1 - Figure 2 As shown, an adjustable concrete guardrail reinforcement spacing control device includes:

[0026] Base plate 1, universal wheels 11 are movably mounted at the four corners of the bottom of base plate 1, and two support rods 12 are fixedly mounted at the top of base plate 1;

[0027] The distance control component 2 is arranged on one side of the top of the bottom plate 1. The distance control component 2 includes a mounting plate 21 movably mounted on one side of the top of the bottom plate 1. An adjusting frame 24 is movably mounted on one side of the mounting plate 21. A start bar 26 is fixedly connected to one side of the adjusting frame 24. A threaded block 28 is movably mounted inside the adjusting frame 24. A pointer 212 is fixedly mounted on one side of the threaded block 28. A scale 211 is arranged on the top of the adjusting frame 24.

[0028] The adjustment component 3 is arranged on one side of the two support rods 12. The adjustment component 3 includes a plurality of mounting grooves 31 opened on one side of the two support rods 12. Two mounting blocks 32 are fixedly installed on the mounting plate 21 close to one side of the support rods 12. The two mounting blocks 32 are slidably fitted with the inner wall of the mounting groove 31. A mounting hole 33 is opened on one side of the two mounting blocks 32. A locking rod 36 is movably installed inside the mounting groove 31.

[0029] Specifically, a mounting plate 21 is movably mounted on one side of the two support rods 12, two sliding rods 22 are fixedly mounted on the side of the mounting plate 21 away from the support rods 12, a slider 23 is movably sleeved between the two sliding rods 22, an adjusting frame 24 is fixedly connected to one side of the slider 23, a starting block 25 is fixedly mounted on one side inside the adjusting frame 24, and a starting bar 26 is fixedly mounted on the side of the starting block 25 away from the adjusting frame 24.

[0030] As can be seen from the above, the two slide bars 22 are used to limit the slider 23 so that the slider 23 can only move in a straight line and simultaneously drive the adjustment frame 24 to move. The starting bar 26 is used as a starting reference point when tying steel bars.

[0031] Specifically, a threaded rod 27 is movably installed between the starting block 25 and the inner wall of the adjusting frame 24 through a bearing, a threaded block 28 is installed on the outer side of the threaded rod 27 through a threaded engagement, the threaded block 28 slides in contact with the inner wall of the adjusting frame 24, an electric clamp 29 is fixedly installed on the side of the threaded block 28 away from the adjusting frame 24, a knob 210 is movably installed on the outer side of the adjusting frame 24, the knob 210 is connected to the shaft of the threaded rod 27 through a transmission connection, a scale 211 is set on the top of the adjusting frame 24, and a pointer 212 is fixedly installed on the side of the threaded block 28 close to the scale 211, and the pointer 212 faces the scale 211.

[0032] As can be seen from the above, the threaded rod 27 can drive the threaded block 28 to move inside the adjustment frame 24 by rotation. The electric clamp 29 is used to clamp the steel bars to be tied. When it moves synchronously with the threaded block 28, the spacing of the steel bars can be controlled. In this embodiment, an inclination sensor is arranged inside the electric clamp 29 to ensure that the clamped steel bars always remain perpendicular to the horizontal line, avoiding the situation where the steel bars are tilted and it is difficult to accurately grasp the spacing when tying in an inclined area on the ground. This allows the device to adapt to a variety of areas and has a wider adaptability. The scale 211 and the pointer 212 can easily see and control the moving distance of the threaded block 28.

[0033] During specific use, the starting bar 26 is placed close to one of the steel bars, and then the steel bar to be tied is clamped by the electric clamp 29. Then, the knob 210 is turned according to the spacing requirement, and the threaded rod 27 drives the threaded block 28 and the electric clamp 29 to move inside the adjustment frame 24 until the pointer 212 points to the specified scale 211 value. At this time, the spacing between the steel bar clamped by the electric clamp 29 and the steel bar stuck to the starting bar 26 is the required value. At this time, the steel bars can be tied. When continuing to tie, there is no need to move the position of the electric clamp 29. Just let the electric clamp 29 clamp the new steel bar and push the adjustment frame 24 back and forth. Refer to the starting method to make the starting bar 26 stick to the second steel bar. At this time, the spacing between the new steel bar clamped by the electric clamp 29 and the previously tied steel bar is consistent. At this time, the binding can continue. Repeated operations can ensure the accuracy and consistency of the steel bar spacing.

[0034] Embodiment 2:

[0035] See also Figure 1 and Figure 3 - Figure 4 As shown, a U-shaped plate 34 is fixedly installed on the outside of the two support rods 12 near the mounting groove 31, a baffle 35 is fixedly installed inside the U-shaped plate 34, and a locking rod 36 is movably installed between the baffle 35 and the U-shaped plate 34 through an opening, one end of the locking rod 36 passes through the inside of the mounting groove 31, and one end of the locking rod 36 extends into the inside of the mounting hole 33, and the locking rod 36 slides and fits against the inner wall of the mounting hole 33.

[0036] Specifically, a reset plate 37 is fixedly installed on the outer side of the locking rod 36 , and two reset springs 38 are connected between the reset plate 37 and the inner wall of the U-shaped plate 34 . The two reset springs 38 are symmetrically arranged on both sides of the reset plate 37 .

[0037] As can be seen from the above, the mounting groove 31 cooperates with the mounting block 32 to realize the rapid disassembly and assembly of the mounting plate 21 and the adjustment frame 24, which is convenient for changing the use height of the adjustment frame 24. At the same time, the mounting hole 33 cooperates with the locking rod 36 to achieve locking of the mounting block 32 to prevent the mounting block 32 from detaching from the inside of the mounting groove 31. The reset plate 37 and the reset spring 38 can drive the locking rod 36 to complete the reset.

[0038] During specific use, it is only necessary to pull the locking rod 36 to move the locking rod 36 away from the mounting slot 31. At this time, the return spring 38 is in a compressed state, and then the mounting block 32 is placed into the mounting slot 31. At this time, the position of the mounting hole 33 and the locking rod 36 just correspond. Then release the locking rod 36, and the locking rod 36 will extend into the mounting hole 33 under the action of the return spring 38 to complete the locking.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
