[0002] With the development of the construction industry, attached lifting scaffolding has been widely used in more and more high-rise building construction due to its safety, reliability and cost-saving characteristics, which also drives the scaffolding industry forward.

[0003] In the prior art, after the guide rail climbs to a corresponding height, it is fixed on the guide rail with a unloading push rod. At this time, only anti-fall mechanisms such as the anti-fall pendulum block are used to block the movement. However, when the unloading push rod fails, since there are many possible heights for the guide rail to be fixed, in the existing mechanical device, the anti-fall pendulum block and the upper guide rail cross bar cannot be triggered to block the movement immediately. When the guide rail falls after climbing, the time of the fall is uncertain, and the guide rail cross bar cannot block the movement immediately, which will cause the guide rail to move down a certain distance and then collide with the anti-fall pendulum block. This distance will accelerate the guide rail, increasing the kinetic energy of the impact, and thereby increasing the impact of the guide rail on the anti-fall mechanism, causing a greater impact on the anti-fall mechanism.

[0040] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below with reference to specific diagrams. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0041] See also Figure 1 - Fig.18 The embodiment of the present invention provides a technical solution: a high-energy swing block type anti-fall device wall support, including a base 1 and a roller 2 arranged at one end of the base 1, a top rod 4 is arranged in the base 1, and a rotating wheel 5 is arranged on the lower side of the top rod 4 and is rotatably arranged in the base 1, a fixing plate 6 is fixedly connected to the side of the top rod 4 away from the roller 2 in the base 1, a shift block 7 is arranged on the lower side of the top rod 4 and is rotatably arranged in the base 1, and a blocking column 12 is abutted on the upper side of the shift block 7, and a reset spring 11 is connected between the shift block 7 and the fixing plate 6, and also includes:

[0042] The locking mechanism 8 is used to stop the lower brake wheel 3 from rotating immediately when the top rod 4 is unloaded, so as to facilitate the subsequent timely braking. The locking mechanism 8 is arranged in the base 1;

[0043] The offset mechanism 9 is used to disengage the brake wheel 3 from the guide rail when the brake wheel 3 is rotated to prevent the rotation from affecting the guide rail. The offset mechanism 9 is arranged in the base 1;

[0044] And the brake mechanism 10 is used for friction braking when the guide rail climbs and suddenly falls, so as to reduce the kinetic energy when the rotating wheel 5 hits the shifting block 7. The brake mechanism 10 is arranged in the base 1 and the brake wheel 3.

[0045] Each roller 2 and brake wheel 3 are arranged opposite to each other.

[0046] Specifically, when unloading is required, the brake wheel 3 can be fixed when it is rotated to any position through the cooperation of the offset mechanism 9 and the locking mechanism 8. At the same time, the brake wheel 3 can also be kept away from the guide rail to prevent the rotation of the brake wheel 3 from affecting the guide rail. Through the braking mechanism 10, the brake wheel 3 can be transformed from the role of auxiliary guide rail movement to the role of reducing the kinetic energy of the guide rail, and the rotation direction of the brake wheel 3 is opposite to the falling direction of the guide rail. The friction force does more work and offsets more of the kinetic energy of the guide rail. At the same time, after the rotating rod on the rotating wheel 5 contacts the shift block 7, the sliding friction between the brake wheel 3 and the guide rail is greater, so that the friction force can be further increased before the guide rail stops completely, thereby further reducing the kinetic energy of the guide rail falling.

[0047] In another embodiment provided by the present invention, the braking mechanism 10 includes a trapezoidal pressure plate 101 movably inserted on the surface of the rotating rod of the rotating wheel 5, the end of the trapezoidal pressure plate 101 located in the rotating wheel 5 abuts against the trapezoidal rod 3 108, and the two opposite sides of the end of the trapezoidal rod 3 108 away from the trapezoidal rod 3 108 both abut against the sliding circular plate 106, the end of the sliding circular plate 106 away from the trapezoidal rod 3 108 is fixedly connected to a transmission rod 107 movably inserted in the rotating wheel 5, and the outer side of the end of the transmission rod 107 located outside the rotating wheel 5 is movably sleeved with a gear set 102, one of the bevel gears of the gear set 102 is fixedly connected to the rotating wheel 5, the end of the transmission rod 107 located outside the rotating wheel 5 abuts against the cone column 1014, and the end of the gear set 102 away from the transmission rod 107 A sleeve column 1012 is fixedly connected, and the sleeve column 1012 is rotatably set in the base 1, and a conical column 1014 is horizontally movably inserted in the sleeve column 1012, and an insertion column 1011 is movably inserted at one end of the sleeve column 1012 away from the conical column 1014, and a spring five 1013 is connected between the insertion column 1011 and the conical column 1014, and the end of the insertion column 1011 away from the sleeve column 1012 is connected to a gear set 2 109, and the other end of the gear set 2 109 is fixedly connected to a rotating shaft 1010, a ratchet 103 is fixedly connected to the outer wall of the rotating shaft 1010, and the ratchet 103 is rotatably set at the inner center of the brake wheel 3, and a pawl 104 that is clamped in the ratchet 103 is rotatably set on the inner wall of the brake wheel 3, and a torsion spring 105 is fixedly connected between the center axis of the pawl 104 and the brake wheel 3.

[0048] Gear set 1 102 and gear set 2 109 each include two bevel gears meshing perpendicularly with each other.

[0049] Specifically, when the rotating rod on the rotating wheel 5 finally contacts the shift block 7, the guide rail cross bar will squeeze the trapezoidal pressure plate 101 downward, and the trapezoidal pressure plate 101 will squeeze the trapezoidal rod three 108 toward the sliding circular plate 106, so that the sliding circular plate 106 and the transmission rod 107 move toward the cone column 1014, and the cone column 1014 is squeezed toward the plug column 1011 by the transmission rod 107, so that the thrust of the cone column 1014 on the plug column 1011 becomes greater and greater, and through the transmission of the plug column 1011, the second ring 87, the first ring 86, the rotating shaft 1010, the ratchet 103 and the brake wheel 3, the vertical pressure between the ratchet 103 and the guide rail becomes greater and greater. The greater the vertical pressure, the greater the sliding friction between the brake wheel 3 and the guide rail, so that the friction can be further increased before the guide rail stops completely, and the kinetic energy of the guide rail falling is further reduced, so as to prevent the kinetic energy of the guide rail falling from having too much influence on the anti-fall mechanism.

[0050] In another embodiment provided by the present invention, the locking mechanism 8 includes a pressure rod 81 fixedly connected to two opposite sides of the top rod 4, the lower side of the pressure rod 81 is located in the base 1 and is movably inserted with a lifting frame 82, a spring 1 83 is fixedly connected between the side wall of one end of the lifting frame 82 and the base 1, a pressure block 85 is movably inserted with the bottom end of the lifting frame 82, and a spring 3 812 is fixedly connected between the upper end of the pressure block 85 and the lifting frame 82, a collar 1 86 is rotatably sleeved on the outer wall of one end of the rotating shaft 1010 close to the gear set 2 109, a collar 2 87 is connected to one side of the collar 1 86, and the collar 2 87 is rotatably sleeved on the outer wall of the plug column 1011, and the collar 1 86 and the collar 2 87 are both horizontally slidably arranged In the base 1, a resistance block 88 is movably inserted on the outer wall of the upper side of the ring 86 at the lower side of the pressure block 85, and a trapezoidal rod 813 is abutted on the lower side of the resistance block 88, and the trapezoidal rod 813 is horizontally slidably set in the ring 86, and a spring 2 84 is fixedly connected between the upper side wall of the trapezoidal rod 813 and the ring 86, and one end of the trapezoidal rod 813 close to the brake wheel 3 extends to the outside of the ring 86, and one end of the trapezoidal rod 813 close to the brake wheel 3 is fixedly connected to an extrusion block 89, and a side of the extrusion block 89 away from the trapezoidal rod 813 is fixedly connected to a plurality of arc-shaped inclined blocks 810 on the brake wheel 3, and a slot 811 is provided on the brake wheel 3 between adjacent arc-shaped inclined blocks 810.

[0051] A plurality of arc-shaped inclined blocks 810 and squeeze blocks 89 are arranged in a ring shape at equal intervals, and an inclined sliding surface is provided at opposite ends of the arc-shaped inclined blocks 810 and the squeeze blocks 89.

[0052] In another embodiment provided by the present invention, the offset mechanism 9 includes a pressing portion 91 fixed to the bottom end of the lifting frame 82, a notch 92 is provided on a side wall of the pressing portion 91 close to the sleeve column 1012, a conical ring 93 is movably inserted in the second sleeve ring 87 at the lower side of the pressing portion 91, and a trapezoidal rod 97 is fixedly connected to one end of the conical ring 93 located in the second sleeve ring 87, the trapezoidal rod 97 is horizontally slidably arranged in the second sleeve ring 87, the other end of the trapezoidal rod 97 abuts against a trapezoidal block 95, and the trapezoidal block 95 is slidably arranged in the second sleeve ring 87 up and down, a spring four 96 is fixedly connected between the upper end of the trapezoidal block 95 and the second sleeve ring 87, the end of the trapezoidal block 95 away from the trapezoidal rod 97 abuts against a fixing rod 94, and the fixing rod 94 is movably inserted in the second sleeve ring 87, and the other end of the fixing rod 94 is fixed to the sleeve column 1012.

[0053] When the pressing portion 91 presses the cone ring 93 inward, the pressing block 85 presses the abutting block 88 downward.

[0054] Specifically, it should be noted that the scaffolding is usually provided with a plurality of anti-falling devices on the same horizontal plane and the same vertical plane, so when the upper end of the top rod 4 is pressed against the guide rail cross bar in turn, the offset mechanism 9 moves the brake wheel 3 away from the guide rail, which will not cause the guide rail to deviate.

[0055] Working principle: when in use, the rollers 2 and brake wheels 3 on both sides are sleeved on the outside of the guide rail, and the two ends of the guide rail are fitted with the rollers 2 and brake wheels 3, and the rotating rod on the rotating wheel 5 is placed between the adjacent cross bars of the guide rail. When unloading is required, the top rod 4 is rotated in the direction of the guide rail, and then the upper end of the top rod 4 is pressed against the cross bar of the guide rail. When the top rod 4 rotates, the pressure rod 81 will rotate counterclockwise and press the lifting frame 82 downward. The lifting frame 82 drives the lower pressing part 91 to press the cone ring 93 downward, so that the cone ring 93 presses the trapezoidal rod 2 97 inward, and then the trapezoidal block 95 is squeezed upward. When the bottom end of the trapezoidal block 95 is separated from the fixed rod 94, the lower pressing part 91 squeezes the cone ring 93, the trapezoidal rod 2 97, the trapezoidal block 95 and the second collar 87 together toward the side away from the brake wheel 3, thereby making the brake wheel 3 away from the guide rail;

[0056] Then, the lifting frame 82 drives the pressing block 85 to press the abutting block 88 downward, and the abutting block 88 presses the trapezoidal rod 1 813 and the squeezing block 89 toward the brake wheel 3. The squeezing block 89 presses the inclined sliding surface on the arc-shaped inclined block 810, so that the arc-shaped inclined block 810 drives the brake wheel 3 to rotate, and finally the squeezing block 89 is inserted into the slot 811, so that the brake wheel 3 is connected with the collar 1 86 and the collar 2 87, so that the brake wheel 3 is fixed. After the pressing part 91 continues to move downward, the notch 92 moves to the cone ring 93, so that the collar 2 87 and the plug 1011 are reset due to the elastic force of the spring 5 1013, and finally the trapezoidal block 95 pops up downward and contacts with the fixing rod 94, and the brake wheel 3 is fixed.

[0057] When the guide rail is climbing, the top rod 4 is away from the guide rail, and the brake wheel 3 can be movable. The rotation of the brake wheel 3 and the roller 2 can reduce the friction with the guide rail and prevent the guide rail from deflecting. When the guide rail is climbing, the brake wheel 3 rotates clockwise, and the rotating wheel 5 also rotates clockwise. The transmission of the rotating wheel 5, the gear set 1 102, the sleeve column 1012, the plug column 1011, the gear set 2 109, the rotating shaft 1010 and the ratchet 103 makes the ratchet 103 rotate counterclockwise. At this time, the pawl 104 and the ratchet 103 will not be stuck. When the guide rail suddenly falls, the brake wheel 3 will rotate counterclockwise, so that the pawl 104 and the ratchet 103 are stuck. The brake wheel 3 drives the pawl 104 to rotate counterclockwise, so that The rotating wheel 5 continues to rotate clockwise. When the rotating rod on the rotating wheel 5 conflicts with the guide rail crossbar, the crossbar presses downward to rotate the rotating wheel 5 counterclockwise. At this time, the ratchet 103 rotates clockwise, and the brake wheel 3 rotates clockwise through the pawl 104. As a result, when the guide rail falls, the rotation direction of the brake wheel 3 is opposite to the falling direction of the guide rail, which can make the brake wheel 3 produce a large friction force on the guide rail, and the clockwise rotation of the brake wheel 3 can increase the distance between the brake wheel 3 and the guide rail due to the friction work. Then the guide rail crossbar contacts the rotating rod on the rotating wheel 5 on its lower side, until the rotating rod on the rotating wheel 5 finally rotates until the rotating wheel 5 conflicts with the shift block 7, and the friction work between the brake wheel 3 and the guide rail ends.

[0058] Finally, when the rotating rod on the rotating wheel 5 conflicts with the shift block 7, the guide rail cross bar will squeeze the trapezoidal pressure plate 101 downward, and the trapezoidal pressure plate 101 will squeeze the trapezoidal rod three 108 toward the sliding circular plate 106, so that the sliding circular plate 106 and the transmission rod 107 move toward the cone column 1014, and the cone column 1014 is squeezed toward the plug column 1011 by the transmission rod 107, so that the thrust of the cone column 1014 on the plug column 1011 becomes greater and greater, and through the transmission of the plug column 1011, the second ring 87, the first ring 86, the rotating shaft 1010, the ratchet 103 and the brake wheel 3, the vertical pressure between the ratchet 103 and the guide rail becomes greater and greater. The greater the vertical pressure, the greater the sliding friction between the brake wheel 3 and the guide rail, so that the friction can be further increased before the guide rail stops completely, and the kinetic energy of the guide rail falling is further reduced, thereby preventing the kinetic energy of the guide rail falling from having an excessive impact on the anti-fall mechanism.
