Description

Technical Field

[0001] The invention belongs to the technical field of protective devices, and in particular relates to a protective device for building construction. Background Art

[0002] Construction protection devices in the field of intelligent building construction are equipment and systems designed to ensure the safety of workers at the construction site and reduce the accident rate. These devices include guardrails, safety nets, monitoring equipment, warning signs and personal protective equipment, etc., which are designed to effectively prevent safety accidents such as falling from heights, being hit by objects, and injuries caused by construction machinery, and ensure the safety of the construction environment. Among them, guardrails are frequently used protective devices. Guardrails can protect workers working at heights and prevent workers from falling from heights;

[0003] Although the existing guardrails can play a protective role, they still have shortcomings. For example, traditional guardrails are usually fixed structures and cannot be quickly adjusted according to changes in site conditions, resulting in insufficient protection in some special cases. Secondly, the materials used in existing guardrails may rust and age after long-term use, reducing the protective effectiveness. The conventional response method is to regularly adjust the position and height of the guardrail according to changes in the construction site, and secondly, apply an anti-corrosion coating on the outside of the guardrail to extend the service life of the guardrail;

[0004] However, the disadvantage of these methods is that regular adjustment of the height of the guardrail involves the problem of disassembly and replacement of the guardrail. In order to pursue structural stability, the existing guardrails are complicated and cumbersome to disassemble. Secondly, an anti-rust coating is applied to the outside of the guardrail. The anti-rust coating is easily worn and fallen off during use, so it cannot prevent rust and aging for a long time. Therefore, a new structure is proposed to solve the above problems.

[0022] The top of the anti-collision roof cover is a slope structure with a slope gradually decreasing from the center to the left and right sides. Reinforcement frames are welded to the outside of the four groups of lifting rods under the anti-collision roof cover. The tops of the four groups of lifting rods are welded and fixed to the bottom of the anti-collision roof cover. Construction workers face the rear side when performing construction work.

The top of the anti-collision roof cover is a slope structure, which can bounce falling objects from above to the left and right sides, protecting the space above the heads of the construction workers, thereby protecting the left and right sides and the rear of the construction workers.

Therefore, there is no need to add additional protective mechanisms on the rear side, and additional protective mechanisms may have the opposite effect of obstructing the line of sight.

[0023] After adopting the above technical scheme, the beneficial effects of the present invention are as follows: by arranging the support rod, the adjusting cylinder, the adjusting rod, the adjusting knob and the support plate, the support rod can be freely rotated to adjust the supporting position of the support plate, and the rotation of the adjusting knob drives the adjusting rod to rotate inside the adjusting cylinder, thereby pushing the adjusting rod to move downward, and then making the support plate contact with the ground, which plays a role in increasing the stability of the supporting base plate and ensures the stability of the overall structure. By arranging the support cylinder, the sliding screw cylinder, the fixed cylinder and the lifting rod, the bottom of the support cylinder is inserted downward into the fixed cylinder, and then the sliding screw cylinder is rotated to make the sliding screw cylinder move downward along the outer side of the second threaded screw tube, and the threaded screw tube one is rotated downward and fixedly connected with the docking groove, and the friction between the threaded screw tube one and the docking groove is increased through the gradual extrusion of the inner side of the threaded screw tube one and the anti-slip layer, so that the connection between the sliding screw tube and the fixed cylinder is tight and stable, thereby improving the overall stability and the overall protection performance.

[0024] By setting a fixing frame, a sponge block and an oil filling port, the inner sides of the two groups of clamping grooves on the inner sides of the two groups of sponge blocks are in close contact with the outer side of the lifting rod, and lubricating oil is injected into the two groups of sponge blocks through the oil filling port, so that the two groups of sponge blocks absorb the lubricating oil and become saturated. When the lifting rod moves up and down, the sponge block evenly applies the lubricating oil to the outer side of the lifting rod through the clamping groove, thereby lubricating and preventing rust on the outer side of the lifting rod. Since the lifting rod is a movable mechanism, it is more susceptible to wear, rust and aging than the fixed tube, the sliding screw tube and the supporting tube. Therefore, the lubricating oil is evenly applied to the outer side of the lifting rod through two groups of sponge blocks, which increases the rust resistance of the lifting rod and prolongs the service life of the lifting rod, thereby ensuring the protective performance of the lifting rod and the anti-collision top cover, and ensuring the long-term stability of the overall structure.

[0058] See also Figure 1 and Figure 2 As an embodiment of the present invention, in actual use, first push the load-bearing base plate 100 to the specified position, then lock the four sets of casters with self-locking structures to keep the load-bearing base plate 100 stable, then rotate the support rod 111 to make the support rod 111 move away from the side of the load-bearing base plate 100 and rotate outward. After rotating to a suitable position, pinch the adjustment button 114 and rotate it clockwise to make the adjustment button 114 drive the adjustment rod 113 to rotate inside the adjustment cylinder 112, so that the adjustment rod 113 is pushed downward through the rotation connection between the outer side of the adjustment rod 113 and the inner side of the adjustment cylinder 112, and the support plate 115 at the bottom of the adjustment rod 113 is moved downward.

When not in use, the above steps can be reversed. First, the four groups of support plates 115 are moved upward and out of contact with the ground, and then the support rod 111 is rotated to be parallel to the side of the load-bearing base plate 100, so that the four groups of stabilizing components 110 can be stored on the side of the load-bearing base plate 100. The final effect is to increase the stability of the load-bearing base plate 100, and it is convenient to use and store.

[0059] See also Figures 1 to 6As the second embodiment of the present invention: Based on the further elaboration of the above embodiment, during installation, firstly start the four sets of electric push rods 440, retract the four sets of lifting rods 410 into the support tube 400, so that the bottom of the four sets of lifting rods 410 is at the lowest point that can be retracted inside the support tube 400, and then rotate the four sets of sliding screw-on tubes 300 respectively, so that the sliding screw-on tubes 300 rotate upward along the threaded screw-on tube 2 430 and rise to the highest point, exposing the bottom of the support tube 400, and then a worker lifts the bottom of the anti-collision top cover 420 with both hands, The bottoms of the four groups of support cylinders 400 are lifted off the ground, and another worker guides the bottoms of the four groups of support cylinders 400 to be inserted into the four groups of fixed cylinders 210. After the insertion is completed, one worker can be removed and one worker can be left to carry out the next installation work. The two groups of symmetrically arranged installation handles 310 are rotated to a horizontal state respectively, and then the two groups of rotating handles are respectively held with both hands to rotate the sliding screw-on cylinder 300 so that the sliding screw-on cylinder 300 moves downward along the outer side of the threaded screw-on tube 2 430. When the threaded screw-on tube 1 at the bottom of the sliding screw-on cylinder 300 is When the threaded tube 320 is opposite to the docking groove 211, the sliding screw-on cylinder 300 is continuously rotated to make the bottom of the threaded screw-on tube 320 rotate downwardly along the bottom of the docking groove 211 to connect. When the threaded screw-on tube 320 moves downwardly, the inner side of the threaded screw-on tube 320 contacts the outer side of the anti-slip layer 212. Since the top radius length of the anti-slip layer 212 is smaller than the bottom radius length, the inner side of the threaded screw-on tube 320 and the outer side of the anti-slip layer 212 are gradually squeezed and tightly pressed during the process of the threaded screw-on tube 320 gradually moving downward, which greatly increases the ease of the threaded screw-on tube. The friction between the handle 320 and the fixed cylinder 210 increases the friction between the sliding screw-on cylinder 300 and the fixed cylinder 210, thereby increasing the friction between the sliding screw-on cylinder 300 and the fixed cylinder 210, and then making the connection between the supporting cylinder 400 and the fixed cylinder 210 more stable and firm. If disassembly is required, only the above steps need to be followed to remove four groups of supporting cylinders 400 and one group of anti-collision top covers 420 at one time. The final effect is that the installation handle 310 can make the rotation of the sliding screw-on cylinder 300 more labor-saving, while ensuring the stability of the overall structure, greatly improving the efficiency of disassembly and installation, and being convenient and reliable to use.

[0060] See also Figure 1 , Figure 3 , Figure 4 and Figure 7As the third embodiment of the present invention: Based on the further elaboration of the above embodiment, after the installation is completed, the hydraulic lift can be started first to lift the manned floor 200 upward (the hydraulic lift is a prior art, and its model can be selected according to the existing models on the market, as long as it can ensure the stability during lifting, and no further description is given), so that the manned floor 200 rises to a specified height, and then the four groups of electric push rods 440 are started at the same time. The four groups of electric push rods 440 are synchronous mechanisms. The electric push rods 440 simultaneously push the lifting rods 410 upward inside the support tube 400, so that the lifting rods 410 move upward from the inside of the support tube 400 (the electric push rods 440 are a prior art, and its model can be selected according to the existing models on the market, and no further description is given), so that the four groups of lifting rods 410 drive the anti-collision top cover 420 to move upward , stop rising after adjusting the height. When performing construction work, the anti-collision top cover 420 can prevent falling objects from high altitude from injuring construction workers. Construction workers face the rear side during construction, and their rear side is blocked by the protective plate 230, and their left and right sides are blocked by a group of protective plates 230 respectively, thereby protecting the construction workers' top, rear and left and right blind spots. At the same time, the height of the lifting rod 410 and the anti-collision top cover 420 can be flexibly adjusted, which greatly increases the flexibility of use. Construction workers face the rear side during construction and can observe the situation at the rear side at any time. At the same time, the construction workers wear safety clothes, and the other ends of the safety clothes are respectively tied to the outside of the two groups of protective plates 1 220 and the group of protective plates 2 230. Therefore, there is no need to add additional protective mechanisms on the rear side, and additional protective mechanisms may have the opposite effect of obstructing vision.

[0061] See also Figure 7 , Figure 8 and Fig. 9As the fourth embodiment of the present invention: during the lifting and lowering of the lifting rod 410 inside the support cylinder 400, the outer side of the lifting rod 410 is always wrapped by two groups of mirror-symmetrical sponge blocks 520, and the sponge blocks 520 absorb a sufficient amount of lubricating oil and reach a saturated state. During the up and down movement of the lifting rod 410, the outer side of the lifting rod 410 rubs against the clamping grooves 521 inside the two groups of sponge blocks 520, so that the two groups of sponge blocks 520 evenly apply the lubricating oil to the outer side of the lifting rod 410 through the two groups of clamping grooves 521, thereby increasing the rust resistance of the lifting rod 410 and lubricating the lifting rod 410 at the same time, reducing the wear of the lifting rod 410. Since the lifting rod 410 is a movable mechanism, Compared with the fixed cylinder 210, the sliding screw cylinder 300 and the supporting cylinder 400, the lifting rod 410 is more susceptible to wear and rust damage. The two sets of oiling mechanisms can provide sufficient lubrication protection for the lifting rod 410, and the lifting rod 410 can be coated with lubricating oil only through a simple lifting action. The operation is simple and convenient. It is known that the sponge block 520 can work normally for one week after being saturated with oil. When the lubricating oil inside the sponge block 520 is insufficient, the sealing top cover can be opened to expose the oil filling port 401, and the lubricating oil can be injected into the two sets of sponge blocks 520 through the oil filling port 401, and then the sealing cover 402 can be re-covered to complete the oil filling. The final effect is to extend the service life of the lifting rod 410 and make it easy to use.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
