When the safety net 200 is lifted, the lifting rope 310 is pulled, the lifting rope 310 pulls the support rod 210 to move toward the direction close to the support frame 100, and the pulley 320 and the lifting rope 310 roll relatively, thereby reducing the friction between the lifting rope 310 and the support frame 100.
Referring to fig. 2 and 5, the locking assemblies 400 are provided in a plurality of sets, and one set of the locking assemblies 400 is provided corresponding to one support rod 210. Every group locking subassembly 400 all includes locking pole 410 and a plurality of locking hook 420, and a plurality of locking hooks 420 set up along the length direction interval in proper order of locking pole 410, and the interval between two adjacent locking hooks 420 equals. Each locking hook 420 is fixedly connected to the locking rod 410.
A plurality of accommodating grooves 111 are formed in the bottom of the accommodating cavity 110, and one accommodating groove 111 corresponds to one locking rod 410. The direction of seting up of every holding tank 111 all is on a parallel with the length direction of lock pole 410, and the length of seting up of every holding tank 111 all is less than corresponding lock pole 410 length. Each lock pole 410 is disposed in the corresponding receiving groove 111, and the lock pole 410 is disposed in parallel to the opening direction of the receiving groove 111. Both ends of each locking rod 410 penetrate into the support frame 100 from the wall of the receiving groove 111. The locking rod 410 is rotatably connected to the support frame 100, and the locking rod 410 is slidably connected to the receiving groove 111 in a direction parallel to the length direction of the locking rod 410.
A plurality of grooves 120 are formed in the supporting frame 100, each groove 120 is communicated with the accommodating cavity 110, and one groove 120 corresponds to one locking hook 420 and is matched with the locking hook 420. When the locking rod 410 is rotated, the locking rod 410 and the support frame 100 rotate relatively, meanwhile, the locking rod 410 drives the locking hook 420 to rotate, the locking hook 420 rotates to the corresponding groove 120, the cavity opening of the accommodating cavity 110 is opened, and the support rod 210 moves to the accommodating cavity 110. The locking bar 410 is rotated reversely again, the locking hook 420 is separated from the groove 120, the locking hook 420 moves into the accommodating chamber 110, and simultaneously the locking hook 420 collides with the support bar 210.
The support frame 100 is provided with a plurality of springs 130, and one spring 130 is provided corresponding to one locking rod 410. The spring 130 and the corresponding locking rod 410 are coaxially arranged, one end of the spring 130 abuts against one end of the locking rod 410, and the other end of the spring 130 is fixedly connected with the support frame 100. When the spring 130 is in a natural unstressed state, the locking hooks 420 are misaligned with the corresponding grooves 120. When the locking lever 410 is rotated, the locking lever 410 is slid first, the spring 130 is compressed, and then the locking hooks 420 are positioned at the corresponding grooves 120. The locking rod 410 is rotated, the locking rod 410 drives the locking hook 420 to move, the locking hook 420 moves to the corresponding groove 120, the locking hook 420 is tightly abutted to the groove 120 under the action of the spring 130, and therefore the effect that a worker can lift and drop the supporting rod 210 conveniently is achieved.
The implementation principle of the safe anti-falling net for the construction engineering is as follows: when the safety anti-falling net is used, the support frame 100 is fixedly connected with a scaffold erected in building construction, so that the support frame 100 is in a horizontal state. When a wounded person falling on the safety net 200 is first treated, the locking rod 410 is pushed, the locking rod 410 slides relative to the receiving groove 111, the spring 130 is compressed, and the locking hook 420 moves to the corresponding groove 120. When the locking rod 410 is rotated, the locking rod 410 and the support frame 100 rotate relatively, the locking hook 420 moves into the groove 120, and the locking hook 420 is separated from the support rod 210. The locking hook 420 is pressed against the groove 120 by the spring 130, so that the locking hook 420 is in a static state.
Loosening lift cords 310 causes pulley 320 to roll relative to lift cords 310. Safety net 200 and bracing piece 210 move towards the direction that is close to ground under the effect of self gravity, make then safety net 200 descend to subaerial, and then reach the effect that makes things convenient for the rescuer to carry out the first aid to the wounded.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
