[0002] Safety railings are facilities that protect people from the risk of falling. They are commonly found in places where there may be a risk of falling. Railings are usually installed on the edge protection of steel temporary bridges to ensure the safety of people when using temporary bridges and prevent injuries caused by accidental falls. In traditional solutions, the edge protection of steel temporary bridges mostly uses channel steel, round steel pipes or square tubes to make railings, and uses bolts or welding to fix and splice the existing railings. However, the height of the existing steel structure railing protection is not adjustable and cannot be quickly adjusted according to different protection needs, which limits the protection scenarios.

[0019] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0020] A manually adjustable lifting steel structure safety railing, such as Figure 1-Figure 5As shown, it includes a longitudinal T-shaped beam 3, a triangular rib for reinforcement is provided on the longitudinal T-shaped beam 3, sleeves 4 are placed on both sides of the longitudinal T-shaped beam 3, the sleeves 4 are detachable connection structures, the lower part of the sleeves 4 are provided with anti-slip grooves 5, a first locking member 6 is connected between the sleeves 4 and the longitudinal T-shaped beam 3, a first railing 1 is slidably connected between the left and right sleeves 4, a second locking member 7 is connected between the first railing 1, the sleeve 4 and the longitudinal T-shaped beam 3, and the left and right parts of the first railing 1 are both It is connected with a buckle 8, and several reserved holes 9 are opened on the left and right parts of the first railing 1. The left side of the first railing 1 is contact-connected with the second railing 2, and three bolts 10 are connected between the second railing 2 and the first railing 1. A lifting assembly 11 is installed on the first railing 1, and the lifting assembly 111 includes a connecting rod 112. The left and right parts of the first railing 1 are movably connected with the connecting rod 112, and the connecting rod 112 is connected with a block 113. The connecting rods 112 are rotatably connected with a lifting rod 111.

[0021] It should be noted that the safety railing is a facility to protect people from the risk of falling. It is commonly used in places where there may be a risk of falling. Steel temporary bridge edge protection usually installs railings to ensure the safety of people when using the temporary bridge and prevent injuries caused by accidental falls. When installing the first railing 1, first place the sleeve 4 at the corresponding position on the longitudinal T-beam 3. The anti-slip pattern 5 can increase the friction between the sleeve 4 and the longitudinal T-beam 3, making the sleeve 4 more stable. Then use the first locking member 6 to lock and fix the sleeve 4 and the longitudinal T-beam 3, and then insert the first railing 1 into the corresponding sleeve 4. The first locking member 6 can lock and fix the sleeve 4 and the longitudinal T-beam 3. The component 6 can play an auxiliary supporting role for the bottom of the first railing 1, and the second locking component 7 is used to lock and fix the sleeve 4, the first railing 1 and the longitudinal T-shaped beam 3, thereby completing the installation of the first railing 1 and the longitudinal T-shaped beam 3. Then, the bolt 10 is used to pass through the corresponding reserved hole 9 to lock the first railing and the second railing 2, so that multiple first railings 1 and second railings 2 can be spliced together to meet the protection requirements of sites of different specifications. At the same time, the protection height of the second railing 2 can be adjusted according to the reserved holes 9 on the first railing 1 and the second railing 2, thereby adapting to the protection requirements of higher heights;

[0022] When the protection height of the first railing 1 needs to be increased, the angle of the block 113 on the connecting rod 112 is rotated to be consistent with the first railing 1, and then the connecting rod 112 is lifted upward, thereby driving the lifting rod 111 to be lifted upward. As the connecting rod 112 is lifted upward, the block 113 will be higher than the first railing 1, and then the block 113 is rotated to a direction perpendicular to the first railing 1, thereby completing the locking of the connecting rod 112 and the first railing 1 by the block 113, thereby increasing the overall protection height of the first railing 1, thereby adapting to protection needs of different heights. This adjustment method is more convenient and can help construction workers save adjustment and installation time, thereby improving work efficiency.

[0023] The above description is merely an example of the implementation of the present invention and is not intended to limit the present invention. Any equivalent substitutions made within the principles of the present invention shall be included within the scope of protection of the present invention. Any matters not fully described in the present invention are prior art known to those skilled in the art.
