Description

Technical Field

[0001] The utility model belongs to the technical field of highway engineering construction, in particular to a safety protection frame. Background Art

[0002] Safety protection frames in highway construction mainly refer to temporary structures erected at the construction site to ensure the safety of workers, prevent objects from falling, and isolate the construction area from other areas; its main functions and effects include:

[0003] 1. Ensure construction safety: The protective frame can provide a relatively closed and stable construction environment, effectively preventing dangerous situations such as falling and splashing of objects that may occur during the construction process, thereby protecting the lives of workers;

[0004] 2. Isolate the construction area: By building a protective frame, the construction area can be effectively isolated from the surrounding environment, reducing the impact of construction on the surrounding environment, while preventing non-construction personnel from mistakenly entering the construction area, ensuring the smooth progress of the construction process;

[0005] 3. Improve construction efficiency: Reasonable protective frame design can optimize the construction process, reduce unnecessary material handling and personnel movement, and thus improve construction efficiency.

[0006] In contrast, a Chinese patent with authorization publication number CN115012729A discloses a safety protection frame for highway engineering construction, including two guardrail posts and a guardrail body. The guardrail body is connected between the two guardrail posts to form a guardrail structure. The guardrail body includes a bottom connecting frame and a top connecting frame arranged parallel to each other. A plurality of railings are equidistantly connected between the bottom connecting frame and the top connecting frame. Both ends of the bottom connecting frame are rotatably connected to the guardrail posts through bearings, and both ends of the top connecting frame are connected to the guardrail posts through elastic locking members. When the guardrail body is collided, the elastic locking members are automatically unlocked.

[0007] The above patent will tip over to avoid a violent collision, but the critical value of the collision force during tipping is fixed and cannot be adjusted, which cannot meet the use requirements of different scenarios. Therefore, a new device needs to be designed. Utility Model Content

DETAILED DESCRIPTION

[0027] 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.

[0028] See also Figure 1-Figure 4 A safety protection frame includes a main device for buffering collisions and avoiding tipping, and also includes three adjustment components evenly arranged on the front of the bottom of the main device for elastic positioning and adjusting the avoidance threshold by the compression amount of the spring 304. A support component for supporting vertical enclosures and bottom sliding release support is arranged between the adjustment component and the main device.

[0029] In this embodiment: the main device includes a baffle 101, a rotating seat 103 is arranged at the bottom of the baffle 101, a rotating shaft 104 is installed between the rotating seat 103 and the baffle 101, two fixed plates 105 are symmetrically arranged on both sides of the front of the rotating seat 103, four ground piles 106 are evenly arranged on the fixed plate 105, and the bottom shape of the ground pile 106 is conical, and a buffer plate 102 is arranged behind the baffle 101. The buffer plate 102 is made of silicone material. The ground piles 106 on the fixed plate 105 are inserted into the ground to fix the device on the ground, so that the baffle 101 is used to enclose the construction environment. When the front of the device is hit, the buffer plate 102 absorbs and buffers the collision. At the same time, the baffle 101 rotates around the rotating shaft 104 under the support of the rotating seat 103, and tilts forward to avoid the collision;

[0030] In this embodiment: the support assembly includes a support rod 201, a first hinge seat 202 and a second hinge seat 203 are respectively provided at both ends of the support rod 201, a hinge shaft 204 is provided in the first hinge seat 202 and the second hinge seat 203, a slider 205 is installed under the second hinge seat 203, the support rod 201 is fixed on the slider 205 through the second hinge seat 203, and the baffle 101 is supported by the first hinge seat 202, and the support rod 201 can rotate around the hinge shaft 204 to ensure that the baffle 101 can be smoothly dumped when avoiding;

[0031] In this embodiment, the adjustment component includes a support plate 301, a slide groove 302 is provided on the support plate 301, two top balls 303 are symmetrically arranged at the rear end of the slide groove 302, and springs 304 are arranged on the opposite sides of the two top balls 303. A screw rod 305 is arranged on the side of the spring 304 away from the top ball 303. The screw rod 305 is threadedly connected to the support plate 301, and a knob 306 is arranged on the end of the screw 305 away from the spring 304. The knob 306 and the screw 305 are integrally formed. When the front of the device is hit, the collision force is transmitted to the support rod 201 by the baffle 101, so that the support rod 201 pushes the slider 205 forward along the slide groove 302 through the second hinge seat 203. At this time, the slider 205 is supported by the top ball 304. 03 is stuck and cannot slide, thereby ensuring the vertical state of the baffle 101. When the collision force is too large, the slider 205 will overcome the elastic force of the spring 304, push the top beads 303 on both sides to move back and forth to squeeze the spring 304, so that it can slide forward, so that the support rod 201 rotates around the hinge shaft 204 under the support of the hinge seat, and the support for the baffle 101 is released, so that the baffle 101 rotates around the rotating shaft 104 under the support of the rotating seat 103, and tilts forward to avoid the collision; the screw rod 305 is rotated by the knob 306 to make the screw rod 305 rotate into the support plate 301, compress the spring 304, and increase the thrust of the spring 304 on the top bead 303, thereby realizing the adjustment of the tipping threshold of the baffle 101 to meet different needs.

[0032] Working principle: the device is fixed to the ground by inserting the ground stakes 106 on the fixing plate 105, so that the baffle 101 can enclose the construction environment; when the front of the device is hit, the buffer plate 102 first absorbs and buffers the collision, and then the collision force is transmitted to the support rod 201 by the baffle 101 through the first hinge seat 202, so that the support rod 201 pushes the slider 205 forward along the slide groove 302 through the second hinge seat 203. At this time, the slider 205 is blocked by the top bead 303 supported by the spring 304 and cannot slide, thereby ensuring the vertical state of the baffle 101; when the collision force is too large, the slider 205 will overcome the elastic force of the spring 304 and push the two sides The top balls 303 move in opposite directions to squeeze the spring 304, thereby sliding forward, causing the support rod 201 to rotate around the hinge axis 204 under the support of the hinge seat, thereby releasing the support for the baffle 101, causing the baffle 101 to rotate around the rotation axis 104 under the support of the rotating seat 103, and tipping forward to avoid collision; the screw rod 305 is rotated by the knob 306 to screw the screw rod 305 into the support plate 301, compressing the spring 304, increasing the thrust of the spring 304 on the top ball 303, thereby increasing the tipping threshold of the baffle 101 to meet different needs, or the tipping threshold can be reduced by the opposite operation, and the baffle 101 can be actively tipped for folding and storage.

[0033] 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.
