Description

Technical Field

[0001] This utility model relates to the field of road guardrail construction technology, and in particular to a guardrail transfer lifting tool. Background Technology

[0002] Common road guardrails typically consist of multiple railings and support piers, with the railings threaded onto the support piers. Currently, during road guardrail assembly, operators first place the support piers, then multiple operators work together to move the railings to the support piers, and finally thread the railings onto the support piers. This method requires multiple operators to complete the assembly and railing movement, increasing the assembly difficulty. Furthermore, during assembly, the high friction between the support piers and railings can cause the support piers to tilt, further complicating the railing installation. Utility Model Content

[0003] This utility model provides a railing transfer lifting tool to overcome the shortcomings of the prior art. It can fix the railing and facilitate its transfer. It can also reduce friction during railing assembly, thereby facilitating the assembly operation and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0005] A railing transfer lifting device includes a lifting plate with side plates at both ends;

[0006] Both ends of the side panel are equipped with rotatable support legs, and the outer wall of the support legs is equipped with connecting pins; the support legs allow the hanging platform to be raised off the ground, thus facilitating the transfer of the railing.

[0007] A connecting seat is rotatably mounted on the connecting pin, and an internal threaded sleeve is rotatably mounted on one of the connecting seats. An adjusting screw is installed inside the internal threaded sleeve, and the adjusting screw is located on the other connecting seat. Through this design, the span of the outrigger can be adjusted by changing the length between the internal threaded sleeve and the adjusting screw, thereby adjusting the height of the hanging plate. This allows the railing to be adjusted according to the assembly height of the railing.

[0008] A rotating seat is installed on the hanging plate, and a rotating head is rotatably mounted on the rotating seat. A lifting screw is installed at the lower end of the rotating head, and a movable plate is installed on the lifting screw. A pair of guide frames are installed on the movable plate, and the vertical sections of the guide frames pass through the hanging plate. In this way, the height of the railing can be finely adjusted during assembly, which facilitates the assembly operation of the railing.

[0009] The movable platform has end plates installed at both ends, and U-shaped rods are installed on the end plates. A first movable plate is movably mounted on one vertical section of the U-shaped rod. An arc plate is provided on the inner end of the first movable plate, and a second movable plate is provided on the other end of the arc plate. The second movable plate is fitted onto the other vertical section of the U-shaped rod, and a clamping screw is screwed to the end of the second movable plate. The upper end of the clamping screw is rotatably mounted on the end plate. The U-shaped rod provides support and constraint for the railing, thus ensuring safety during railing transfer. Furthermore, the movable arc plate acts on the upper wall of the railing, further clamping and positioning the railing.

[0010] Furthermore, the lower end of the outrigger is equipped with rollers. The rollers facilitate the operator's movement of the railing.

[0011] Furthermore, the inner end of the internal threaded insert is provided with anti-slip patterns. The anti-slip patterns facilitate the operator's rotation of the internal threaded insert.

[0012] Furthermore, a rotating disk is provided at the lower end of the clamping screw. The rotating disk facilitates the operator's rotation of the clamping screw.

[0013] The advantages of the above technical solution are:

[0014] This utility model addresses the problems existing in the prior art by facilitating the transfer operation during railing assembly. During the transfer, the railing can be stably and securely fixed, and during assembly, it can be adjusted according to the actual assembly position, thereby assisting operators in quickly completing the assembly work. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will provide a further detailed description of this utility model in conjunction with the accompanying drawings.

[0017] Figure 2 A three-dimensional structure of one embodiment is shown. Figure 2 .

[0018] Figure 3 A magnified view of point A is shown. Detailed Implementation

[0019] like Figures 1-3 As shown, a railing transfer lifting device includes a lifting plate 1, with side plates 10 at both ends of the lifting plate 1.

[0020] Both ends of the side plate 10 are rotatably equipped with support legs 2, and the outer wall of the support leg 2 is provided with connecting pins 21. The lower end of the support leg 2 is provided with a roller 20.

[0021] A connecting seat 3 is rotatably mounted on the connecting pin 21. An internal threaded sleeve 30 is rotatably mounted on one of the connecting seats 3. An adjusting screw 32 is mounted inside the internal threaded sleeve 30. The adjusting screw 32 is mounted on the other connecting seat 3. The inner end of the internal threaded sleeve 30 is provided with anti-slip patterns.

[0022] A rotating seat 40 is installed on the hanging plate 1. A rotating head 41 is rotatably mounted on the rotating seat 40. A lifting screw 42 is provided at the lower end of the rotating head 41. A movable plate 43 is provided on the lifting screw 42. A pair of guide frames 44 are installed on the movable plate 43. The vertical section of the guide frame 44 passes through the hanging plate 1.

[0023] The movable plate 43 has end cross plates 5 installed at both ends. A U-shaped rod 50 is installed on the end cross plates 5. A first movable plate 51 is movably installed on one vertical section of the U-shaped rod 50. An arc plate 52 is provided on the inner end of the first movable plate 51. A second movable plate 53 is provided on the other end of the arc plate 52. The second movable plate 53 is sleeved on the other vertical section of the U-shaped rod 50. A clamping screw 55 is screwed to the end of the second movable plate 53. The upper end of the clamping screw 55 is rotatably mounted on the end cross plate 5. A rotating disk 56 is provided at the lower end of the clamping screw 55.

[0024] In this embodiment, during the auxiliary transfer and assembly of the railing, the angle between the legs 2 is first adjusted according to the approximate assembly height of the railing. During adjustment, the operator can rotate the internal threaded sleeve 30 to move the adjusting screw 32 inward or outward from the internal threaded sleeve 30, thereby decreasing or increasing the angle between the legs 2. Next, the operator places the railing onto the U-shaped bar 50 and then rotates the clamping screw 55 using the rotating disk 5. The rotation of the clamping screw 55 will drive the arc plate 52 to move downward, causing the arc plate 52 to act on the upper wall of the railing, thus finally completing the fixing of the railing. It is best to place the U-shaped bar 50 in the middle position of the railing during fixing, as this position will prevent tilting or other problems when the railing is moved. When the guardrail is moved to the designated position, the lifting screw 42 is rotated by the rotating head 41, and the height of the guardrail is adjusted under the drive of the lifting screw 42. After the adjustment is completed, the operator pushes the guardrail to move inward to the support block and completes the assembly operation of the road guardrail.

[0025] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
