Description

Technical Field

[0001] The utility model relates to the technical field of building guardrails, in particular to a building construction safety protection mechanism. Background Art

[0002] Construction refers to the production activities in the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations. It includes foundation engineering construction, main structure construction, roof engineering construction, decoration engineering construction, etc. In order to improve the safety of the construction site and prevent unauthorized personnel from entering the construction site, construction workers will install guardrails outside the construction area for isolation and protection.

[0003] An existing construction safety protection mechanism (publication number: CN220522236U) has at least the following disadvantages: the above-mentioned device can drive the telescopic isolation plate to rise and fall during installation by setting a lifting mechanism to meet the convenience during transportation and the protection requirements of the construction area. However, since the area of ​​the telescopic isolation plate is fixed, a gap will appear at the bottom when the telescopic isolation plate is lifted and lowered. As the telescopic isolation plate continues to rise, the gap at the bottom of the telescopic isolation plate will gradually increase, allowing people or animals to pass through the gap, thereby failing to achieve a protective effect. If the lifting height of the telescopic isolation plate is too small, the transportation convenience requirement cannot be met. For this reason, the present utility model is proposed.

[0012] Reference Figure 1-Figure 4 A construction safety protection mechanism comprises two bases 1, the two bases 1 are arranged at intervals, a telescopic assembly is arranged on the top surface of the base 1, the telescopic assembly comprises a screw rod 2 rotatably connected to the top surface of the base 1, the outer wall of the screw rod 2 is threadedly connected with a threaded sleeve 201, the outer walls of the screw rod 2 and the threaded sleeve 201 are movably sleeved with a plurality of connecting rings 202, the connecting ring 202 close to the top end of the threaded sleeve 201 is fixed to the outer wall of the threaded sleeve 201, a telescopic sleeve 203 is fixed to the outer wall of the connecting ring 202 located on the left side of the device, and a telescopic sleeve rod 204 is fixed to the outer wall of the connecting ring 202 located on the right side of the device, and the telescopic sleeve rod 204 is inserted into the inside of the telescopic sleeve 203.

[0013] Reference Figure 1-Figure 4In this embodiment, a first bevel gear 206 is fixed to the bottom end of the screw rod 2, a driving rod 207 is rotatably connected to the front side of the base 1, a second bevel gear 208 is fixed to one end of the driving rod 207, the first bevel gear 206 is meshed with the second bevel gear 208, and a plurality of telescopic sleeves 204 and a plurality of telescopic sleeves 203 are provided with a steel cable 205 between two telescopic sleeves 204 adjacent to each other and between two telescopic sleeves 203 adjacent to each other. By providing two bases 1, a threaded sleeve 201 and a screw rod 2 are provided on the base 1, so that the screw rod 2 can drive the threaded sleeve 201 to rise, and by A plurality of extendable and retractable telescopic sleeves 203 and telescopic sleeve rods 204 are arranged between each threaded sleeve 201 and the two screw rods 2, and each adjacent telescopic sleeve 203 and telescopic sleeve rod 204 are connected by a steel cable 205. During the ascending process of the threaded sleeve 201, the telescopic sleeve 203 and the telescopic sleeve rod 204 can be pulled and unfolded, so that the plurality of telescopic sleeves 203 and the telescopic sleeve rod 204 evenly cover the space between the two threaded sleeves 201 and the two screw rods 2, thereby effectively avoiding leaving an excessively large gap to cause people or animals to pass through the device through the gap while taking into account the maximum lifting and unfolding distance of the device.

[0014] Reference Figure 1-Figure 4 In this embodiment, a limiting sleeve 3 is fixed on the top surface of the base 1, and the screw rod 2 and the threaded sleeve 201 are movably sleeved inside the limiting sleeve 3. A sliding groove 301 is provided on the outer wall of the limiting sleeve 3. The width of the sliding groove 301 is equal to the maximum width of the telescopic sleeve 204 and the telescopic sleeve 203. The diameter of the connecting ring 202 is equal to the inner diameter of the limiting sleeve 3. The connecting ring 202 near the bottom end of the limiting sleeve 3 is fixed to the inner wall of the limiting sleeve 3. The limiting sleeve 3 can limit the connecting ring 202 to prevent the inner diameter of the connecting ring 202 from being larger than the screw rod 2, which causes the connecting ring 202 to fit with the outer wall of the screw rod 2 and hinder the lifting and lowering of the threaded sleeve 201.

[0015] Reference Figure 1-Figure 4 In this embodiment, a first limiting ring 4 is fixed to the outer wall of the telescopic sleeve 203, and a second limiting ring 401 is fixed to the outer wall of the telescopic rod 204. By setting and using the first limiting ring 4 and the second limiting ring 401, the maximum telescopic stroke of the telescopic sleeve 203 and the telescopic rod 204 can be limited to prevent the telescopic rod 204 from escaping from the inside of the telescopic sleeve 203.

[0016] Reference Figure 1-Figure 4 In this embodiment, universal wheels 5 are fixed to the bottom surface of the base 1 near the front and rear sides. The universal wheels 5 are provided to facilitate the staff to better move and arrange the device.

[0017] Reference Figure 1-Figure 4In this embodiment, the outer walls of the two limiting sleeves 3 are fixed with mounting plates 6, and three mounting holes 601 are opened on one side of the mounting plates 6. The two mounting plates 6 are staggered. By setting the mounting plates 6 and the mounting holes 601, it is convenient for the staff to connect and install two adjacent protective devices together, so that multiple protective devices form a whole protective guardrail.

[0018] From the above description, it can be seen that the above-mentioned embodiment of the utility model achieves the following technical effects: in use, by moving the device to the protection point and then pulling the two bases 1, the two bases 1 are moved away from each other, at this time, the telescopic sleeve 204 slides inside the telescopic sleeve 203, and the telescopic sleeve 204 and the telescopic sleeve 203 extend to the maximum distance, and then the rotating drive rod 207 drives the second bevel gear 208 to rotate, and under the meshing action of the first bevel gear 206 and the second bevel gear 208, the first bevel gear 206 rotates and drives the screw rod 2 to rotate, and under the threaded connection action of the screw rod 2 and the threaded sleeve 201, the threaded sleeve 201 moves upward, and pulls the telescopic sleeve 203 and the telescopic sleeve 204 near the top of the threaded sleeve 201 to move upward, because the connecting ring 202 near the bottom end of the limiting sleeve 3 is fixed to the inner wall of the limiting sleeve 3, at this time, multiple telescopic sleeves 20 3 and the telescopic sleeve rod 204 are pulled upward, and the spacing between the multiple telescopic sleeves 203 and the telescopic sleeve rod 204 becomes larger until the steel cable 205 is completely straightened, and then the arrangement and installation of the device can be completed. By setting the limiting sleeve 3, the connecting ring 202 can be limited to prevent the connecting ring 202 from being attached to the outer wall of the screw rod 2 due to the inner diameter of the connecting ring 202 being larger than the screw rod 2, which hinders the lifting and lowering of the threaded sleeve 201. By setting and using the first limiting ring 4 and the second limiting ring 401, the maximum telescopic stroke of the telescopic sleeve 203 and the telescopic sleeve rod 204 can be limited to prevent the telescopic sleeve rod 204 from escaping from the inside of the telescopic sleeve 203. By setting the universal wheel 5, it is convenient for the staff to better move and arrange the device. By setting the mounting plate 6 and the mounting hole 601, it is convenient for the staff to connect and install two adjacent protective devices together, so that multiple protective devices form a whole protective fence.
