Technical Field

[0001] This application belongs to the field of building engineering technology, specifically relating to a civil engineering safety warning device. Background Technology

[0002] The warning device is set at the top of the pit, 1.5 meters from the edge of the pit. When construction workers are working at the bottom of the pit, they can see the warning device at the top of the pit. As the depth of the pit increases, the warning device may become invisible at the central axis of the pit, so it is necessary to raise the height of the warning device.

[0003] In the prior art, the raising and lowering of the warning device is achieved through the cooperation of a lifting rod and a sleeve. Several positioning holes are provided along the axis on the outer peripheral wall of the lifting rod, and a through hole is provided on the sleeve that is aligned with one of the positioning holes. Then, the warning device can be fixed at the adjusted height by inserting a pin into the sleeve and the lifting rod.

[0004] The above adjustment process requires construction workers to lift the lifting rod upwards, and also to pay attention to the height of the lifting rod and limit its rotation, so that the positioning hole is aligned with the through hole on the sleeve, before it can be positioned by inserting the pin. The operation is cumbersome. Utility Model Content

[0033] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0034] Please refer to the following: Figures 1 to 8 This application describes a civil engineering safety warning device. The device includes two support sleeves 1, a warning sign 2, and an electric push rod 3. The two support sleeves 1 are arranged along the height direction and connected by a connecting plate 4. The bottom of the support sleeves 1 is fixed at a predetermined position at the top of the pit, away from the edge. The warning sign 2 is connected to the top of the support sleeves 1. Support rods 21, corresponding to the support sleeves 1, are connected to the warning sign 2. A guide structure 5 is detachably connected to the bottom of each support rod 21. Rollers 6, which rotatably engage with the inner sidewall of the support sleeves 1, are located on the sidewall of the guide structure 5. A gap exists between the support rods 21 and the support sleeves 1 to reduce friction and wear. The electric push rod 3 is connected to the connecting plate 4. The drive end of the electric push rod 3 is connected to the warning sign 2. The drive end of the electric push rod 3 can drive the warning sign 2 to rise and fall. The connection between the support rods 21 and the bottom of the warning sign 2 can be welded.

[0035] This application provides a civil engineering safety warning device. Compared with the prior art, the warning sign 2 can be moved upward by pushing the drive end of the electric push rod 3 upward, increasing the height of the warning sign 2; the warning sign 2 can be moved downward by resetting the drive end of the electric push rod 3, decreasing the height of the warning sign 2. Two support rods 21 are slidably engaged with corresponding support sleeves 1. The bottom of the support rods 21 is connected to the guide structure 5, and the guide structure 5 is rotatably engaged with the inner wall of the support sleeve 1 through rollers 6, which can reduce the friction between the guide structure 5 and the support sleeve 1. During the raising and lowering of the warning sign 2, the guide structure 5 can also play a horizontal limiting role for the warning sign 2, making the warning sign 2 more stable during the raising and lowering process. Here, the horizontal direction refers to the front-back direction and the left-right direction of the warning sign. With the above-mentioned settings of this application, the raising and lowering process of the warning sign 2 is simple to operate, and the wear between the support rods 21 and the support sleeves 1 can be reduced during the raising and lowering process.

[0036] The working principle of the electric linear actuator 3, the wiring connection between the electric linear actuator 3 and the power supply, and the location of the power supply are all existing technologies and will not be described in detail here.

[0037] The electric push rod 3 is located in the middle between the two support sleeves 1. The cylinder of the electric push rod 3 is connected to the connecting plate 4, and the drive end of the electric push rod 3 is connected to the bottom of the warning sign 2. When the drive end extends upward, it can drive the warning sign 2 to move upward. When the drive end returns to its original position downward, the warning sign 2 can move downward.

[0038] In some embodiments, such as Figures 1 to 8 As shown, the side wall of the support sleeve 1 has an installation port 11 near the bottom, and the installation port 11 communicates with the interior of the support sleeve 1; the guide structure 5 can be placed into the support sleeve 1 through the installation port 11.

[0039] The above configuration facilitates the installation of the guide structure 5 on the support rod 21, as detailed below:

[0040] First, insert the support rod 21 from the top of the support sleeve 1. When the end of the support rod 21 is inserted to a position close to the bottom of the support sleeve 1, insert the guide structure 5 into the support sleeve 1 through the mounting port 11 and connect the guide structure 5 to the support rod 21. At this time, the roller 6 on the guide structure 5 can contact the inner wall of the support sleeve 1. During the sliding process of the guide structure 5 in the support sleeve 1, the guide structure 5 can reduce the friction between the guide structure 5 and the support sleeve 1 by rolling cooperation with the inner wall of the support sleeve 1 through the roller 6.

[0041] After the guide structure 5 is inserted into the support sleeve 1 through the mounting port 11, in order to improve the stability of the guide structure 5 and reduce the possibility of the guide structure 5 detaching from the mounting port 11, a sealing plate 7 is provided at the mounting port 11. The inner side of the sealing plate 7 has a protrusion 71 that contacts the rollers 6 of the guide structure 5. After the sealing plate 7 is fixed on the support sleeve 1, the protrusion 71 contacts the rollers 6 on one side of the guide structure 5, and the rollers 6 on the other three sides of the guide structure 5 contact the corresponding inner sidewalls of the support sleeve 1. With the above arrangement, all four sidewalls of the guide structure 5 can roll in cooperation with the four inner sidewalls of the support sleeve 1.

[0042] The connection between the sealing plate 7 and the support sleeve 1 can be a bolt connection. Specifically, the sealing plate 7 has a through hole, and the outer peripheral wall of the support sleeve 1 has a threaded hole that communicates with the sealing plate 7. After the sealing plate 7 seals the installation port 11, the sealing plate 7 is fixed to the support sleeve 1 by bolts.

[0043] In some embodiments, such as Figures 1 to 8 As shown, the two support sleeves 1 are arranged in the left-right direction relative to each other, and the direction perpendicular to the left-right direction on the support sleeve 1 is the front-back direction. That is, among the four side walls of the support sleeve 1, excluding the left and right sides, the direction of the remaining two sides is the front-back direction. At least one roller 6 is rotatably arranged on the left and right side walls of the guide structure 5, because in the left-right direction, the guide structures 5 in the two support sleeves 1 can cooperate with each other, thereby playing a role in left and right limiting.

[0044] At least two rollers 6 are rotatably arranged on the side walls of the guide structure 5 in both the front and rear directions. Therefore, the front and rear direction limit cannot be achieved by the cooperation of two guide structures 5. So, at least two rollers 6 can be arranged on the front and rear sides of a single guide structure 5 respectively. By increasing the contact position, the purpose of front and rear limit can be achieved.

[0045] In some embodiments, such as Figures 1 to 8 As shown, the guide structure 5 is provided with support seats 51 on both the left and right sides, and the roller 6 is rotatably engaged with the support seats 51. With the above arrangement, the roller 6 can be installed on the support seats 51 on the left and right sides of the guide structure 5. The diameter of the roller 6 on the left and right sides of the guide structure 5 is larger than the diameter of the roller 6 on the front and rear sides of the guide structure 5, so support seats 51 need to be provided on the left and right sides of the guide structure 5.

[0046] The diameters of the rollers 6 on the front and rear sides of the guide structure 5 are small, so placement grooves 52 are provided on both the front and rear sides of the guide structure 5 to place the rollers 6 in the placement grooves 52; the guide structure 5 has a through hole that runs through the axis of the placement groove 52, and the rollers 6 in the placement groove 52 have a central hole; a rotating shaft is inserted into the guide structure 5, and the rotating shaft is inserted into the central hole to make the rollers 6 rotate around the rotating shaft.

[0047] Taking the rollers 6 on the front and rear sides of the guide structure 5 as two examples, after the rollers 6 on the front and rear sides of the guide structure 5 are installed, the two rollers 6 on the front and rear sides of the guide structure 5 are in contact with the inner wall of the support sleeve 1, thus restricting the back-and-forth swing of the guide structure 5.

[0048] The guide structure 5 has three or more rollers 6 on both the front and rear sides.

[0049] In some embodiments, such as Figures 1 to 8 As shown, the support rod 21 has a T-shaped groove 22, and the guide structure 5 is connected to a T-shaped slider 53, which slides in conjunction with the T-shaped groove 22; wherein, the guide structure 5 and the support rod 21 are fixed by bolts.

[0050] When installing the guide structure 5 on the support rod 21, align the T-shaped slider 53 on the guide structure 5 with the T-shaped groove 22 on the support rod 21, and then slide the T-shaped slider 53 into the T-shaped groove 22 to achieve initial fixation of the guide structure 5 and the support rod 21.

[0051] The guide structure 5 also has a mounting plate 54 with a through hole; the support rod 21 has a threaded hole aligned with the through hole of the mounting plate 54. After the guide structure 5 and the support rod 21 are inserted into place, the mounting plate 54 is fixed to the support rod 21 with bolts to finally fix the position between the guide structure 5 and the support rod 21.

[0052] After the guide structure 5 wears out, the guide structure 5 can be removed from the mounting port 11 by opening the sealing plate 7 and removing the bolts between the guide structure 5 and the support rod 21, making it easy to replace the guide structure 5.

[0053] In some embodiments, such as Figures 1 to 8 As shown, a cover plate 12 is detachably connected to the top of the support sleeve 1, and a positioning component 13 is connected to the bottom of the cover plate 12; the cross-sectional dimension of the guide structure 5 is larger than the cross-sectional dimension of the support rod 21 located in the support sleeve 1, the positioning component 13 is located on the movement path of the guide structure 5, and the positioning component 13 can contact the guide structure 5 to limit the highest position of the guide structure 5.

[0054] The cover plate 12 is connected to the support sleeve 1 by bolts. The top of the support sleeve 1 has a threaded hole, and the cover plate 12 has a through hole that is aligned with the threaded hole at the top of the support sleeve 1. After the cover plate 12 is placed on the support sleeve 1, the cover plate 12 is fixed to the support sleeve 1 by bolts.

[0055] To reduce friction between the cover plate 12 and the support rod 21, there is a gap between the through hole on the cover plate 12 and the support rod 21; there is also a gap between the positioning component 13 and the support rod 21.

[0056] When the support rod 21 is in its lowest position, the cross-sectional dimension of the part of the support rod 21 outside the support sleeve 1 is larger than the cross-sectional dimension of the part of the support rod 21 inside the support sleeve 1, thus forming a step between the two parts of the support rod 21; when the support rod 21 slides down to its lowest position, the step on the support rod 21 can contact the top of the cover plate 12.

[0057] In some embodiments, such as Figures 1 to 8 As shown, a stabilizing plate 14 is fixedly installed at the bottom of the support sleeve 1. Several connecting holes are provided on the stabilizing plate 14 at intervals along its circumference. The stabilizing plate 14 is fixed to the top of the pit at a preset position from the edge by anchor bolts.

[0058] With the above settings, the support sleeve 1 can be stably fixed at a preset position at the top of the pit, which is 1.5 meters away from the edge of the pit.

[0059] Concrete is poured at the top edge of the foundation pit, and anchor bolts are pre-embedded at the locations where support sleeve 1 needs to be installed. After the concrete has solidified and reached the preset strength, support sleeve 1 is installed.

[0060] In some embodiments, such as Figures 1 to 8 As shown, the warning sign 2 is equipped with an audible and visual alarm 8 on its top, and reflective stickers 9 are affixed to the front and back sides of the warning sign 2 respectively; the audible and visual alarm 8 is electrically connected to an external controller, and the audible and visual alarm 8 and the external controller are connected to a power supply; with the above settings, the audible and visual alarm 8 will light up at night, which can serve as a warning; the warning sign 2 has warning text written on it, and the warning sign 2 is coated with reflective paint.

[0061] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
