Description

Technical Field

[0001] This utility model relates to the field of protective device technology, and in particular to a construction site protective device. Background Technology

[0002] Construction site safety devices are various facilities or equipment used to ensure the safety of construction sites and prevent personnel injuries and equipment damage. They are usually designed and installed according to specific uses and environments.

[0003] Currently, existing construction site safety devices involve placing safety signs in front of the construction area to warn pedestrians and vehicles. However, different warning signs are needed for different content to remind pedestrians of the precautions ahead. The replacement of existing warning signs is mostly done by loosening bolts, which is too cumbersome and not conducive to the quick replacement of warning signs. Utility Model Content

[0004] The purpose of this utility model is to solve the problem of the overly cumbersome replacement of warning signs in the existing technology, and to propose a construction site protection device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A construction site protection device includes two parallel columns and a warning board. Three equidistant transverse beams are fixedly installed between the two columns. Multiple equidistant longitudinal beams are fixedly installed on the three transverse beams. Two symmetrically arranged limiting blocks are fixedly installed on the transverse beams. Two pairs of symmetrically arranged fixing blocks are fixedly installed on the warning board. A limiting rod disposed within the limiting block is fixedly installed between the two pairs of symmetrically arranged fixing blocks. The limiting block is provided with a limiting post for limiting the limiting rod.

[0007] Preferably, two symmetrically arranged guide rods are fixedly installed on the transverse beam, and springs are sleeved on the outer walls of both guide rods, with the bottom ends of the springs fixedly installed on the transverse beam.

[0008] Preferably, the outer walls of the two guide rods are jointly fitted with a [missing information - likely a specific type of sleeve]. The structure has support rods, and the upper ends of the two springs are respectively fixedly installed on the two support rods.

[0009] Preferably, the upper ends of the two limiting posts are respectively fixedly installed on the support rods, and a connecting rod is fixedly installed between the two support rods, with a handle fixedly installed at the upper end of the connecting rod.

[0010] Preferably, a rotating seat is fixedly installed on the upper end of each of the two columns, and a laser light is fixedly installed on each of the two rotating seats.

[0011] Preferably, a counterweight is fixedly installed at the bottom of each of the two columns, and a limit ring is fixedly installed at the top of each of the two guide rods.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. This utility model allows the connecting rod to move upward by pulling the handle, which in turn moves the support rod upward, causing the support rod to move the limiting post synchronously. This releases the limiting post from the limiting rod, facilitating quick replacement of warning signs and making it convenient for staff to use.

[0014] 2. This utility model turns on the laser lights and rotates the laser lights by rotating the base, so that the visible rays irradiated by multiple laser lights form a closed area, which is convenient for warning pedestrians at night. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-5A construction site protection device includes two parallel columns 1 and a warning plate 15. Three equidistant transverse beams 2 are fixedly installed between the two columns 1 by bolt assemblies. Multiple equidistant longitudinal beams 3 are fixedly installed on the three transverse beams 2 by bolt assemblies. The arrangement of transverse beams 2 and longitudinal beams 3 makes the fixation between the two columns 1 more secure. Two symmetrically arranged limiting blocks 7 are fixedly installed on the transverse beams 2 by bolt assemblies. Two pairs of symmetrically arranged fixing blocks 16 are fixedly installed on the warning plate 15 by bolt assemblies. Limiting rods 17 set in the limiting blocks 7 are fixedly installed between the two pairs of symmetrically arranged fixing blocks 16 by welding. Limiting posts 9 are provided on the limiting blocks 7 to limit the limiting rods 17.

[0023] Two symmetrically arranged guide rods 10 are fixedly installed on the transverse beam 2 to limit the movement direction of the connecting rod 13. Springs 11 are sleeved on the outer wall of both guide rods 10, and the bottom end of the springs 11 is fixedly installed on the transverse beam 2.

[0024] The outer walls of the two guide rods 10 are jointly fitted with a common shape. The structure has a support rod 8, and the upper ends of the two springs 11 are respectively fixedly installed on the two support rods 8 by welding, so that the springs 11 can pull the support rods 8, and the support rods 8 can drive the limit post 9 to reset.

[0025] The upper ends of the two limiting posts 9 are respectively fixedly installed on the support rods 8, and a connecting rod 13 is fixedly installed between the two support rods 8. A handle 14 is fixedly installed on the upper end of the connecting rod 13.

[0026] Both columns 1 are fixedly mounted with rotating seats 5 by bolt assemblies. Both rotating seats 5 are integrally fixed with laser lights 6, which facilitates the rotation of laser lights 6 so that they can illuminate different positions.

[0027] Both columns 1 are fixedly installed with counterweights 4 at their bottom ends. The counterweights 4 make the columns 1 more stable and prevent the warning board 15 from being blown over by strong winds. Both guide rods 10 are fixedly installed with limit rings 12 at their top ends to prevent the support rod 8 from sliding off the guide rod 10.

[0028] It should be noted that the bolt assembly is existing technology, specifically including the bolt and bolt hole. The specific model and specifications of the rotating seat 5 and laser lamp 6 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts existing technology in this field, so it will not be elaborated here.

[0029] The functional principle of this utility model can be explained through the following operation methods:

[0030] In use, by pulling the handle 14, the handle 14 drives the connecting rod 13 to move, and the connecting rod 13 drives the support rods 8 fixed at both ends to move linearly under the limit of the guide rod 10. Both support rods 8 pull the spring 11 and move the limit post 9 upward, releasing the limit on the limit rod 17, and allowing the limit rod 17 to slide out from the limit block 7, so that different warning plates 15 can be quickly replaced.

[0031] When the equipment is used in a nighttime environment, the laser light 6 is turned on to emit a visible beam. The laser light 6 is rotated by the rotating base 5 so that it illuminates the outer surface of the other equipment, forming a visible closed loop around the area that needs protection, thus warning pedestrians.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
