Description

Technical Field

[0001] The utility model relates to the technical field of guardrail construction, in particular to an auxiliary positioning tool for guardrail construction. Background Technique

[0002] A guardrail is a facility used to protect the safety of areas such as roads, bridges, and buildings. It can effectively block possible risk factors such as vehicles and pedestrians, providing safety protection. During the construction of guardrails, generally, the guardrail columns are first fixedly buried in the ground, and then the guardrail crossbars are fixed between multiple guardrail columns. At present, in the installation construction of steel pipe guardrails, most adopt the traditional construction method of mechanical hoisting in cooperation with manual use of bolts for installation.

[0003] Chinese Patent Publication No. CN222333474U discloses an auxiliary positioning tool for guardrail construction. By hoisting construction, the guardrail crossbar is hoisted on the clamping seat, and then the guardrail crossbar can be moved through the bottom plate for installation. It will not occupy the construction machinery for a long time, facilitating the construction machinery to carry out other guardrail hoisting operations, greatly improving the installation efficiency and reducing the installation cost. The support crossbar with adjustable height can adapt to the installation requirements of guardrail crossbars with different heights. Through two clamping seats, it is convenient to dock two guardrail crossbars, and the installation process is more stable and fast.

[0004] Although the above patent does not require a hoisting machine when installing the crossbar, before fixing the crossbar between the two clamping seats, a hoisting machine is still needed, and the hoisting machine will also shake when hoisting the crossbar, requiring the staff to stabilize the hoisted crossbar and then fix it between the two clamping seats. Content of the Utility Model

[0005] The purpose of the utility model is to provide an auxiliary positioning tool for guardrail construction to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] An auxiliary positioning tool for guardrail construction includes a bottom plate one and a bottom plate two which are symmetrically arranged up and down. The bottom plate two slides up and down above the bottom plate one. Both sides of the top surface of the bottom plate two are fixedly connected with support frames. Four corners of the bottom surface of the bottom plate one are fixedly connected with rollers. A rotating mechanism is rotatably arranged above the bottom plate two. A fixing mechanism for clamping and fixing the crossbar is arranged on the top surface of the rotating mechanism. The rotating mechanism includes a rotating plate that rotates between the two support frames.

[0008] Furthermore, two symmetrical fixing blocks are fixedly connected to the top surface of the second base plate. A worm gear ring is fixedly connected to the bottom surface of the rotating plate. A worm that meshes with the worm gear ring is rotatably connected between the two fixing blocks. One end of the worm penetrates through the fixing block at the corresponding position. A motor is fixedly connected to the top surface of the second base plate, and the output end of the motor is fixedly connected to the worm.

[0009] Furthermore, a connecting block is fixedly connected to the bottom surface of the rotating plate, and rotating shafts are fixedly connected to both ends of the connecting block and are rotatably connected to the support frames at the corresponding positions.

[0010] Furthermore, notches are formed at one ends of the first base plate and the second base plate away from the motor, and the width of the notches is greater than the width of the rotating plate.

[0011] Furthermore, the fixing mechanism includes two symmetrical clamping plates that slide on the top surface of the rotating plate. A first rectangular frame is fixedly connected to the middle of the top surface of the rotating plate, and a bidirectional screw rod that penetrates and is screwed with the two clamping plates is rotatably connected between the two ends inside the first rectangular frame.

[0012] Furthermore, second rectangular frames are fixedly connected to both ends of the top surface of the rotating plate. A sliding rod that penetrates and slides with the two clamping plates is rotatably connected between the two ends inside the second rectangular frame. Anti-slip pads are fixedly connected to one side surfaces of the two clamping plates facing each other.

[0013] Furthermore, four electric push rods distributed in a rectangle are fixedly connected between the first base plate and the second base plate, and a battery pack is detachably connected to the top surface of the first base plate.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] When taking the cross bar, there is no need to use a hoisting machine to place the cross bar in the fixing mechanism, which can avoid the cross bar slipping and hitting the staff during the hoisting process. Since one end of the cross bar is always in contact with the ground, it is relatively labor-saving for the staff to lean the cross bar against the fixing mechanism, reducing the physical consumption of the staff.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figure 1 - Figure 4 , in the embodiment of the present invention, a construction auxiliary positioning tool for guardrails includes a first bottom plate 1 and a second bottom plate 4 which are symmetrically arranged up and down. The second bottom plate 4 slides up and down above the first bottom plate 1. Support frames 11 are fixedly connected to both sides of the top surface of the second bottom plate 4. Roller 16 is fixedly connected to each of the four corners of the bottom surface of the first bottom plate 1. A rotating mechanism 2 is rotatably arranged above the second bottom plate 4. A fixing mechanism 3 for clamping and fixing the cross bar is arranged on the top surface of the rotating mechanism 2. The rotating mechanism 2 includes a rotating plate 21 that rotates between the two support frames 11.

[0023] Specifically, first, the staff moves the device to the place where the cross bars are stacked. Then, by rotating the rotating plate 21, the rotating plate 21 drives the fixing mechanism 3 to tilt. Then, the staff can lift the stacked cross bars from the end far away from the rotating plate 21, making the stacked cross bars change from horizontal to inclined until the cross bars lean against the inside of the fixing mechanism 3 (similar to the hour hand of a clock rotating clockwise from 9 o'clock to 1 o'clock or 2 o'clock). Then, continue to lean the cross bars against the fixing mechanism 3 in the same way until the fixing mechanism 3 is full. Then, fix multiple cross bars through the fixing mechanism 3 and make the rotating plate 21 rotate in the reverse direction to return to its original position (as Figure 1 shown). Then, move the device between two columns where the cross bars need to be installed. When the device takes the cross bars, it does not need to use a hoisting machine to place the cross bars in the fixing mechanism 3, which can avoid the cross bars falling and hitting the staff during the hoisting process. Since one end of the cross bar is always in contact with the ground, it is relatively labor-saving for the staff to lean the cross bar against the fixing mechanism 3, reducing the physical consumption of the staff.

[0024] Embodiment 1

[0025] AsFigure 3 As shown in the figure, in this embodiment, two symmetrical fixing blocks 12 are fixedly connected to the top surface of the second base plate 4. A worm gear ring 22 is fixedly connected to the bottom surface of the rotating plate 21. A worm 23 meshing with the worm gear ring 22 is rotatably connected between the two fixing blocks 12. One end of the worm 23 penetrates through the fixing block 12 at the corresponding position. A motor 24 is fixedly connected to the top surface of the second base plate 4. The output end of the motor 24 is fixedly connected to the worm 23. A connecting block 25 is fixedly connected to the bottom surface of the rotating plate 21. Rotating shafts fixedly connected to the corresponding support frames 11 are fixedly connected to both ends of the connecting block 25. Notches 13 are formed at one ends of the first base plate 1 and the second base plate 4 away from the motor 24. The width of the notch 13 is greater than the width of the rotating plate 21.

[0026] In this embodiment, the worm gear ring 22 is an incomplete structure (as Figure 3 shown, it is a D-shaped structure). The rotating plate 21 is fixed to both ends of the worm gear ring 22, and the axis of the worm gear ring 22 and the axis of the rotating shaft are at the same height. By driving the motor 24, the worm 23 can drive the rotating plate 21 to rotate through the worm gear ring 22. The rotating rotating plate 21 can drive the fixing mechanism 3 to rotate, so that the fixing mechanism 3 follows the rotating plate 21 and is in an inclined state, facilitating the staff to lean the cross bar against the fixing mechanism 3.

[0027] Embodiment Two

[0028] As Figure 4 shown, in this embodiment, the fixing mechanism 3 includes two symmetrical clamping plates 31 sliding on the top surface of the rotating plate 21. A first rectangular frame 32 is fixedly connected to the middle of the top surface of the rotating plate 21. A bidirectional screw 33 penetrating and screwing with the two clamping plates 31 is rotatably connected between the two ends inside the first rectangular frame 32. Second rectangular frames 34 are fixedly connected to both ends of the top surface of the rotating plate 21. A sliding rod 35 penetrating and sliding with the two clamping plates 31 is rotatably connected between the two ends inside the second rectangular frame 34. Anti-slip pads are fixedly connected to the opposite side surfaces of the two clamping plates 31.

[0029] In this embodiment, first, the distance between the two clamping plates 31 is adjusted by rotating the bidirectional screw 33 so that the distance between the two clamping plates 31 is slightly greater than the diameter of the cross bar. Then, the staff leans the cross bar against the two clamping plates 31. When enough cross bars are placed between the two clamping plates 31, the two clamping plates 31 are used to clamp and fix multiple cross bars through the bidirectional screw 33, so that the multiple cross bars are flush with each other, preventing the cross bars from being squeezed out by the two clamping plates 31. The anti-slip pads can increase the friction between the clamping plates 31 and the cross bar.

[0030] Embodiment Three

[0031] As Figure 2As shown, in this embodiment, four electric push rods 14 distributed in a rectangle are fixedly connected between the first bottom plate 1 and the second bottom plate 4, and a battery pack 15 is detachably connected to the top surface of the first bottom plate 1.

[0032] In this embodiment, first, the motor 24 and the four electric push rods 14 are electrically connected to the battery pack 15 through wires, so that the battery pack 15 provides power for the electric push rods 14 and the motor 24. The cross bar fixed between the two clamping plates 31 can be lifted by the electric push rods 14, so that the cross bar can be installed at different heights between the two columns.

[0033] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced by the present invention. Any reference signs in the claims should not be regarded as limiting the claims involved.

[0034] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
