AI Technical Summary
The ladders on existing steel structure construction platforms have a reduced coefficient of friction due to mud adhering to the crossbars when climbing, increasing the risk of slipping.
Anti-slip plates A and B are installed on the surface of the ladder's crossbar. Anti-slip plate A and anti-slip plate B are connected by a fan-shaped groove, a round rod, a rotating arm, and a torsion spring. Anti-slip plate B drives the ball bearings to slide to reduce friction and prevents dirt from entering through a sealing ring. When anti-slip plates A and B rotate, the dirt falls off.
This effectively avoids slipping due to reduced friction from the mud, ensuring safety during the climbing process.

TECHNICAL FIELD
[0001] The utility model relates to steel structure construction rack technical field, concretely is a kind of anti-skid mechanism of steel structure construction rack. BACKGROUND
[0002] Steel structure construction rack is usually composed of column, crossbeam, platform and ladder and moving wheel, is a kind of temporary support structure used in the steel structure construction process, column is the main vertical support member, bears the vertical pressure of entire rack and construction load, crossbeam is used to connect column, forms an integral structure with each column, and provides horizontal support for construction platform, platform is placed on the crossbeam of frame, thereby forming a work platform on the frame, usually ladder is installed on one side to facilitate climbing, construction rack can provide a relatively flat and safe work platform at different heights for construction personnel, so that they can conveniently access steel structure components to carry out various construction operations, such as bolt connection, weld inspection.
[0003] The existing related technology often has the following defects: when steel structure needs to be constructed, the worker first needs to climb to the platform of the rack by ladder, and the soil on the shoe sole is easy to adhere to the crossbar of the ladder. The existence of soil changes the nature of the contact surface of the crossbar. The soil itself has a certain softness and slipperiness. It will form an intermediate layer between the shoe sole and the crossbar. The friction coefficient of this intermediate layer is usually much smaller than that between the clean shoe sole and the crossbar. If the soil contains a certain amount of water, the damp soil will become more slippery, further reducing the friction coefficient. Water will weaken the adhesion of soil on the crossbar, and it is easy to flow under the friction of the shoe sole. When a person climbs, the pressure of the foot sole will cause the damp soil to spread around, like applying a layer of lubricant between the shoe sole and the crossbar, greatly increasing the possibility of slipping. Therefore, the crossbar of the ladder of the existing rack is engraved with anti-skid lines or installed with protective pads with anti-skid lines, but the soil will embed into the anti-skid lines, which will reduce the friction between the foot sole and the crossbar, causing the worker to slip when climbing the ladder of the rack.

Because the soil will simultaneously dry and solidify into a block on the surfaces of the anti-slip plates A and B, the rotation of the anti-slip plate B will cause the dried soil on the surfaces of the anti-slip plates A and B to twist and crack into small pieces. At this time, the soil will fall from the worker's feet between the anti-slip plate A or anti-slip plate B. When the worker's feet step on both anti-slip plates A and B at the same time, the soil has already fallen off the surfaces of the anti-slip plates A and B, thereby preventing the worker from slipping due to the soil. It is also convenient to remove the soil from the surfaces of the anti-slip plates A and B when stepping on the crossbar of the ladder, thereby preventing the soil from reducing the friction between the foot and the crossbar, and thus preventing the worker from slipping when climbing the ladder.

DETAILED DESCRIPTION
[0028] Referring to Figure 1 The utility model provides a technical scheme: an anti-skid mechanism of steel structure construction rack, including frame 1, moving wheel 2, table plate 3, ladder 4, the ladder 4 is installed in one side of frame 1, the surface of ladder 4 is installed with several crossbars 5, the surface of crossbar 5 is uniformly fixedly connected with several anti-skid plates A 601, the surface of crossbar 5 is opened with several fan-shaped grooves 602, several fan-shaped grooves 602 are respectively opened in both sides of anti-skid plate A 601, both sides of the inner wall of fan-shaped groove 602 are rotatably connected with round rod 603, and one end of two round rods 603 is fixedly connected with rotating arm 604 and is close to each other, and the camber surface of round rod 603 is covered with torsional spring 605, and both ends of torsional spring 605 are fixedly connected with the inner wall of fan-shaped groove 602 and the surface of rotating arm 604 respectively, and one end of rotating arm 604 is fixedly connected with anti-skid plate B 606, and the surface of crossbar 5 is slidably connected with one side of anti-skid plate B 606, by setting anti-skid structure 6, reach when the crossbar 5 of the ladder 4 of convenient in stepping on can remove the soil on the surface anti-skid plate A 601 and anti-skid plate B 606, to avoid the friction between the soil of lowering foot and crossbar 5, to avoid the situation of foot slipping when climbing ladder 4.
[0029] Referring to Figure 2 - Figure 7As shown, in the present embodiment: the surface anti-skid strips of the anti-skid plate A601 and the anti-skid plate B606 are arranged transversely, the thickness of the anti-skid plate B606 is higher than that of the anti-skid plate A601, the longitudinal anti-skid strips can further improve the anti-skid effect, and the higher anti-skid plate B606 than the anti-skid plate A601 can make the soles of the staff first step on the surface of the anti-skid plate B606. The surface of the anti-skid plate A601 is provided with an arc-shaped hole 607, the length of the arc-shaped hole 607 is greater than the slot of the fan-shaped groove 602, the inner wall of the arc-shaped hole 607 is slidably penetrated by a connecting rod 608, and the two ends of the connecting rod 608 are respectively fixedly connected with two anti-skid plates B606. Since the connecting rod 608 is used to drive multiple anti-skid plates B606 to rotate at the same time, it does not need too much force, so the diameter of the connecting rod 608 is relatively small. The size of the slot of the fan-shaped hole determines the angle of rotation of the connecting rod 608, and the length of the arc-shaped hole 607 is greater than the slot of the fan-shaped groove 602, so as to avoid the connecting rod 608 from colliding with the inner wall of the arc-shaped hole 607 when rotating, thereby avoiding the connecting rod 608 from being damaged due to the collision. The two sides of the rotating arm 604 are fixedly connected with two protective pads 609, the protective pads 609 are made of rubber material, and the protective pads 609 can avoid the rotating arm 604 from being damaged due to the direct impact on the inner wall of the fan-shaped groove 602. The side of the anti-skid plate B606 close to the horizontal rod 5 is fixedly connected with a sealing ring 610, the sealing ring 610 is a hollow cavity, and the sealing ring 610 is installed on the side of the anti-skid plate B606 close to the horizontal rod 5. Therefore, the sealing ring 610 can block the soil and the mud water contained in the soil from entering the position of the anti-skid plate B606 and the horizontal rod 5 support, thereby avoiding the soil from drying and being solidified on the anti-skid plate B606 and the horizontal rod 5 support to affect the movement thereof. The side of the anti-skid plate B606 close to the horizontal rod 5 is rotatably connected with a plurality of rolling balls 611, the anti-skid plate B606 can drive the rolling balls 611 to slide along the circular surface of the horizontal rod 5, and the rolling balls 611 can reduce the friction between the anti-skid plate B606 and the horizontal rod 5 support, thereby facilitating the movement of the anti-skid plate B606.
[0030] The working principle is that when the worker uses the trestle to construct the steel structure, the worker will step on the crossbar 5 of the ladder 4 to climb to the platform 3 to construct. Since the height of the anti-skid plate B 606 is slightly higher than that of the anti-skid plate A 601, when stepping on the crossbar 5, the soles will first contact the anti-skid plate B 606. After the soles of the worker contact the anti-skid plate B 606, a downward force will be generated. The anti-skid plate B 606 will slide on the surface of the crossbar 5 by the downward force. The anti-skid plate B 606 will drive the ball 611 to slide along the arc surface of the crossbar 5. The ball 611 will reduce the friction between the anti-skid plate B 606 and the crossbar 5 support, thereby facilitating the movement of the anti-skid plate B 606. The sliding of the anti-skid plate B 606 will drive the rotating arm 604 to rotate. The rotating of the rotating arm 604 will drive the round rod 603 to rotate in the fan-shaped groove 602. The rotating of the rotating arm 604 will cause the torsional springs 605 on both sides to be twisted. When the rotating arm 604 drives the protective pad 609 to adhere to one side in the fan-shaped groove 602, the rotating arm 604 will stop rotating, thereby stopping the anti-skid plate B 606 from rotating. When the anti-skid plate B 606 stops rotating, the soles of the worker will step on the surfaces of the anti-skid plate A 601 and the anti-skid plate B 606 at the same time. Since the crossbar 5 has the anti-skid plate A 601 and the anti-skid plate B 606, the friction between the soles and the crossbar 5 is improved when climbing, thereby avoiding the situation of slipping. When the soles of the worker step on another crossbar 5 away from the anti-skid plate B 606 and the anti-skid plate A 601, the mud attached to the soles will adhere to the anti-skid plate A 601 and the anti-skid plate B 606 on the crossbar 5. Since the side close to the crossbar 5 of the anti-skid plate B 606 is provided with a sealing ring 610, the sealing ring 610 will block the mud and the mud water contained in the mud from entering the position of the anti-skid plate B 606 and the crossbar 5 support, thereby avoiding the mud from drying and sticking to the anti-skid plate B 606 and the crossbar 5 support to affect the movement. The anti-skid plate B 606 will reset by the torsional force of the torsional spring 605 until the worker climbs to the platform 3. At this time, the anti-skid plate A 601 and the anti-skid plate B 606 on the crossbar 5 will have mud adhered thereto. When the worker uses the ladder 4 to go down to the ground, the mud on the anti-skid plate A 601 and the anti-skid plate B 606 will dry and stick to the surface. At this time, when the worker steps on the anti-skid plate B 606, the anti-skid plate B 606 will rotate. Since the mud will dry and stick to the surfaces of the anti-skid plate A 601 and the anti-skid plate B 606 to form an integral block, the rotation of the anti-skid plate B 606 will cause the mud dried and stuck to the surfaces of the anti-skid plate A 601 and the anti-skid plate B 606 to twist and crack into small pieces. At this time, the mud will fall from between the soles of the worker and the anti-skid plate A 601 or the anti-skid plate B 606. When the soles of the worker step on the anti-skid plate A 601 and the anti-skid plate B 606 at the same time, the mud has fallen from the surfaces of the anti-skid plate A 601 and the anti-skid plate B 606, thereby avoiding the situation that the worker slips due to the mud.The anti-skid plates B606 can be rotated by the connecting rods 608, so that when one foot is stepped on the anti-skid plate B606, several anti-skid plates B606 can be rotated simultaneously, and then the mud adhered to the anti-skid plates A601 and the anti-skid plates B606 is removed, and the above operation is repeated when the worker steps on the ground, so that the mud on the anti-skid plates A601 and the anti-skid plates B606 is removed when the worker steps on the ground, and the situation that the feet slip when the ladder 4 is climbed is avoided.
