DETAILED DESCRIPTION

[0025] 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.

[0026] like Figure 1-Figure 4 As shown, a bridge construction safety anti-fall device includes a main frame 1, two connectors 2 are fixedly provided on the left side of the outer surface of the main frame 1, two splicing mechanisms 3 are provided on the right side of the outer surface of the main frame 1, sliding grooves 4 are provided at both ends of the left and right sides of the front side of the surface of the main frame 1, an adjusting plate 5 is slidably provided inside the sliding groove 4, and positioning grooves 501 are evenly distributed on the rear side of the surface of the adjusting plate 5, and a locking mechanism 8 is provided on the upper end of the main frame 1 at the rear side of the opening of the sliding groove 4.

[0027] By adopting the above technical solution, the connector 2 can be stably, conveniently and quickly installed with the splicing mechanism 3, so that the length of the splicing device can be flexibly adjusted according to actual conditions to meet the use requirements of the device, and effectively expand the application range of the device; and when two anti-fall devices are spliced, no additional bolt fixing parts are required;

[0028] The adjusting plate 5 can slide inside the sliding groove 4 to adjust the height up and down.

[0029] Furthermore, the splicing mechanism 3 includes a connecting block 301 fixedly mounted on the right side of the surface of the main frame 1 , and a slot 302 is provided on the surface of the connecting block 301 .

[0030] By adopting the above technical solution, the slot 302 provides a space for installing the connector 2 on the surface of the connecting block 301 .

[0031] Furthermore, the splicing mechanism 3 also includes a sink groove 303 formed at the front and rear sides of the right end of the inner surface of the slot 302 , and thrust springs 304 are fixedly provided on both the left and right sides of the inner surface of the sink groove 303 .

[0032] By adopting the above technical solution, the sink 303 provides the baffle 305 with sufficient space for shrinking and moving.

[0033] Furthermore, the splicing mechanism 3 also includes a baffle 305 fixedly installed at one end opposite to the thrust spring 304, the right side of the surface of the baffle 305 is set as an inclined surface, and a pull rod 306 is fixedly set in the middle of the opposite side of the surface of the baffle 305, and the pull rod 306 slides through the connecting block 301.

[0034] By adopting the above technical solution, the connector 2 can use the inclined surface of the baffle 305 to push the baffle 305 to shrink, thereby opening the slot 302 for splicing;

[0035] The thrust spring 304 can be quickly reset after the baffle 305 loses the pushing pressure of the plug-in component 2, and secondarily blocks the opening of the slot 302, so that the plug-in component 2 can be stably assembled with the connecting block 301;

[0036] The pull rod 306 can be manually pulled twice to shrink and move the baffle 305, open the slot 302, and disassemble the connector 2;

[0037] The shape of the connector 2 is a transversely arranged "T" shape, and a splicing mechanism 3 is divided into two sets of upper and lower baffles 305 that can limit the horizontal rod of the connector 2 up and down, and cooperate with the right side limit of the upper baffle 305 to enable the connector 2 to be stably assembled.

[0038] like Figure 5-Figure 7 As shown, the shapes of the slide groove 4 and the adjustment plate 5 are set to match each other in a "T" shape, a sub-frame 6 is fixedly installed on the front end of the adjustment plate 5, and a barrier net 7 is fixedly set on the inner side of the surface of the main frame 1 and the sub-frame 6.

[0039] By adopting the above technical solution, when the adjustment plate 5 slides along the slide groove 4, the sub-frame 6 can be driven to adjust, thereby extending the height of the entire device;

[0040] The gaps between the barrier nets 7 can effectively reduce the blowing force of the crosswind on the left and right sides of the bridge deck, making the wind resistance of the device extremely small, and preventing the device from tipping over due to the crosswind.

[0041] Furthermore, the locking mechanism 8 includes a fixed plate 801 fixedly installed on the upper end of the main frame 1, a tension spring 802 is fixedly installed on the rear side of the surface of the fixed plate 801, an insertion rod 803 is fixedly installed on the rear end of the tension spring 802, the front end of the insertion rod 803 slides through the fixed plate 801, and the lower part of the surface of the penetration part of the front end of the fixed plate 801 is set as an inclined surface.

[0042] By adopting the above technical solution, the inclined surface below the front end of the insertion rod 803 enables the edge of each positioning groove 501 to push the insertion rod 803 to move backward when the adjustment plate 5 moves upward;

[0043] The upper side of the insertion rod 803 is a normal cylindrical surface. After the height movement adjustment is completed, the tension spring 802 pulls the insertion rod 803 to insert into the corresponding positioning groove 501 to fix the adjustment plate 5, thereby fixing the adjustment position of the sub-frame 6.

[0044] Furthermore, a support foot 9 is fixedly installed below the surface of the main frame 1, and a screw suction cup 10 is threadedly provided through the middle of the surface of the support foot 9.

[0045] By adopting the above technical solution, the screw suction cup 10 rotates downward to closely adhere to the bridge deck and is adsorbed, thereby improving the stability of the device.

[0046] Working principle: When using the bridge construction safety anti-fall device, first, support the device with the support feet 9 and place it on both sides of the bridge, then turn the screw suction cup 10 downward to make the screw suction cup 10 adhere to the bridge deck for adsorption and fixation, assemble the anti-fall device according to the protection length on both sides of the bridge deck, insert the connector 2 horizontally into the slot 302 of the connecting block 301, use the inclined surface to push the baffle 305 to squeeze the thrust spring 304 to shrink into the sink 303, and then open the slot 302 to open. The plug-in component 2 can be smoothly inserted into the slot 302. When the plug-in component 2 is fully inserted, the thrust spring 304 uses its own elastic force to push the baffle 305 to move toward the middle of the slot 302 to close the slot 302. Since the left side of the baffle 305 is a right-angled surface, the plug-in component 2 cannot push the baffle 305 to retract from the left side. A splicing mechanism 3 is divided into two groups of upper and lower baffles 305 to limit the horizontal rod body of the plug-in component 2 up and down, and cooperates with the right side limit of the upper baffle 305 to enable the plug-in component 2 to be inserted smoothly into the slot 302. 2 is stably and conveniently and quickly installed with the splicing mechanism 3 until it is assembled to the required length. Then, according to the height of different bridge deck protection requirements, the sub-frame 6 can slide up and down under the limit of the slide groove 4 using the adjusting plate 5. The sub-frame 6 slides upward to expand the protection height of the upper end of the main frame 1, and then the overall height of the device can be flexibly adjusted according to actual conditions. When the adjusting plate 5 moves up, the inclined surface will be used to push the plug rod 803 backward to pull the tension spring 802 to extend. When it is adjusted to the required height, the pushing of the sub-frame 6 is stopped. At this time, the tension spring 802 will be pulled by the elastic force to pull the plug rod 803 into the corresponding positioning groove 501, thereby fixing the position of the adjusting plate 5. The entire anti-fall device is protected by the barrier net 7. The gap between the barrier net 7 mesh bodies can effectively reduce the blowing force of the crosswind on the left and right sides of the bridge deck, so that the wind resistance of the device is extremely small, avoiding the situation where the crosswind is blown and the device is overturned due to excessive wind resistance. This is the working principle of the bridge construction safety anti-fall device.
