a vertical push plate 7 is fixedly connected below the horizontal anti-falling baffle 10;
among the scaffold frame anti-falling device, when the second extension board 6 promotion push pedal 7 of dog-ear shaped plate reachs maximum distance, prevent that the round steel crosspiece of baffle upper surface distance from its top possesses difference in height H that resets, difference in height H that resets satisfies:
H/V1 is far larger than T0, T0 is the reset time of the first reset spring 8 when the second support plate 6 of the bevel-shaped plate pushes the push plate 7 to the maximum distance, V1 is the normal descending speed of the scaffold,
and H/V2 is far smaller than T0, and V2 is the average dropping speed of the scaffold under the condition of runaway.
As shown in figure 1, the invention is suitable for an attached scaffold which is provided with a plurality of parallel round steel transverse bars according to the national standard, the fixing surface of the anti-falling device is fixed on the outer vertical surface of a building, and the basic principle of anti-falling is that when the scaffold is detected to rapidly fall at an abnormal speed, the scaffold is fixed on the anti-falling device through the round steel transverse bars.
The specific operation principle of the present invention will be described below by taking the specific embodiment shown in fig. 1 as an example.
Under the normal state, the scaffold is automatically fixed in height and is arranged near a building according to engineering construction standards, the distance between the scaffold and the outer vertical surface of the building is generally 450 mm, the first support plate 5 of the angle bending plate of the anti-falling device is in an approximately horizontal state and is fixed by a certain round steel rail, the second support plate 6 is in an approximately vertical state and is fixed on the right side of the push plate 7 by the push plate 7 below the anti-falling baffle, at the moment, the first reset spring 8 is basically in a natural extension state, the second reset spring 13 is also basically in a natural extension state or has smaller tensile deformation, and the tensile force generated by the tensile deformation of the second support plate 6 in the vertical state has a certain tendency of counterclockwise rotation and is close to the push plate 7.
When the attached scaffold is normally lifted, when the lower edge of the first supporting plate 5 is blocked by another round steel transverse baffle which is positioned below the first supporting plate 5 in a normal state, the lower edge naturally acts clockwise along the rotating shaft, as shown in fig. 2, the bevel-shaped plate acts clockwise, and the connecting arm 12 connected with the first return spring 8 is far away, so that the first return spring 8 is stretched; meanwhile, the second support plate 6 is far away from the push plate 7, and the push plate 7 is not stressed and does not move; when the first supporting plate 5 rotates to exceed a certain angle, the round steel transverse bar crosses the first supporting plate 5, and the first supporting plate 5 loses the support of the round steel transverse bar and is stretched by the first return spring 8 to return to the normal state shown in fig. 1. The process is repeatedly circulated, and in the process of lifting the scaffold, the whole anti-falling device only rotates and turns back periodically by the angle-folded plate, and other components do not act.
When the attached scaffold descends at a constant speed according to construction operation rules, the speed is usually 2 mm per second or close to the speed, when the first supporting plate 5 is up along being stopped by another round steel crosspiece above the first supporting plate 5 under the normal state, the counter-clockwise motion along the rotating shaft naturally occurs, as shown in fig. 3, the counter-clockwise motion of the second supporting plate 6 enables the second supporting plate 6 to push the push plate 7, the push plate 7 drives the anti-falling baffle to move leftwards horizontally and moves to the lower side of the orthographic projection of the round steel crosspiece, at the moment, the first reset spring 8 is stretched due to the movement of the anti-falling baffle, and the second reset spring 13 is also in a stretching state due to the far away of the connecting arm.
Under the state of uniform descending, the anti-falling baffle plate does not block the normal descending of the scaffold; through setting up push pedal 7 length, the scaffold lifting speed is taken into account synthetically, vertical interval between the round steel crosspiece, the terminal factors such as displacement in the horizontal direction of second extension board 6, through experimental verification back, can set up the level and prevent weighing down the high position of baffle 10, make and rotate the surface part that the round steel crosspiece is closest to the pivot when first extension board 5 is terminal, be first extension board 5 this moment promptly and break away from when contacting the critical point of round steel crosspiece, prevent weighing down the round steel crosspiece that baffle upper surface kept away from its top and still possess a difference in height H that resets, in case first extension board 5 breaks away from contacting the round steel crosspiece, whole dog-ear shaped plate is promptly reset by second reset spring 13 rapidly, originally, second extension board 6 that leans on push pedal 7 breaks away from push pedal 7, push pedal 7 is after losing the thrust of second extension board 6, horizontal pullback under first reset spring 8's effect.
First extension board 5 breaks away from when contacting the critical point of round steel crosspiece, the scaffold still needs time H/V1 to make the scaffold stop by the anti-falling baffle and block, wherein V1 is the falling velocity when the scaffold normally descends, according to the construction requirement, the scaffold falling velocity generally is several millimeters per second, according to common knowledge, first reset spring 8 drags the required reset time T0 of anti-falling baffle pullback within ten seconds or even shorter, can set up this difference in height H that resets for centimetre magnitude if 7 centimetres, then H/V1=35 seconds, enough prevent that the baffle is pulled back by first reset spring 8 and resets before being blockked by the round steel crosspiece.
Under the abnormal falling state, the scaffold dropping speed is far higher than the normal dropping speed, H/V2 is far lower than T0, V2 is the average dropping speed of the scaffold under the out-of-control state, and it needs to be explained that the scaffold can move in an acceleration mode under the out-of-control state, but the overall average dropping speed is usually far higher than the normal dropping speed. Supposing that the time required for pulling back the anti-falling baffle by the spring is 1 second, the reset height difference H is set to be 7 cm, according to common knowledge, the first second movement distance reaches 5 meters immediately under the movement of a free falling body, and the height of the reset height difference is far greater than the height of the reset height difference of 7 cm, so that the reset height difference is short enough when the anti-falling baffle falls freely, and the anti-falling baffle is blocked by a round steel transverse baffle before the anti-falling baffle is pulled back, so that the anti-falling is realized.
A more accurate discussion of the calculation process is as follows:
when the scaffold falls freely, the reset height difference H between the anti-falling baffle and the round steel transverse baffle can be calculated to obtain the time for the anti-falling baffle and the round steel transverse baffle to collide with each other and clamp the scaffold body, namely the time T required for falling the reset height difference H, the free falling usually occurs in the normal falling operation process,
H=V0*T+1/2GT2
wherein V0The initial speed of the carriage movement, assumed to be 2 mm/s,
g is gravity acceleration, and G =9.8 m/s is taken2
From this the time T =0.02 seconds can be deduced,
assuming that the falling speed is influenced by the friction of surrounding obstacles, it is reduced to V0If the constant motion of =2 meters per second is still far higher than the safe operation speed, T = H/V can be calculated0=0.035 seconds.
When the frame body falls, the push plate 7 drives the anti-falling baffle to move forwards, the extension length of the first return spring 8 is L, the pull-back force F = K L in the initial state, and K is the stiffness coefficient of the spring; in the whole pulling process, allowance is made, the pulling force is not reduced along with the reduction of the deformation of the spring but is kept unchanged, the friction force is 0.2 times of the gravity, the pulling process is uniform acceleration movement, and the pulling safety distance L1=0.2L of the anti-falling baffle is assumed, namely the round steel crosspiece can be blocked by the anti-falling baffle within the safety distance.
L1=1/2a*T0 2
a=(F-0.2MG)/M，
F=K*L
Taking K =60, M =2 kg, L = 0.1M,
by calculation, T0=0.45s
T0=0.45s satisfies the reset time T0And the time T required by the falling reset height difference H is far longer than that required by the abnormal falling. After the difference in height H that resets falls promptly, first reset spring 8 does not reset far away, is enough to make and prevents weighing down the baffle and is blockked by round steel crosspiece 2, in case blockked by round steel crosspiece 2, scaffold frame self gravity is prevented weighing down the baffle completely and is supported, prevents weighing down the baffle and receives strong frictional force, and the pull-back force that first reset spring 8 produced is not enough to continue to drag and prevents weighing down baffle and fixed position, realizes preventing weighing down. The tail end of the anti-falling baffle is provided with the groove 15, so that the round steel crosspiece 2 falls into the groove 15 to be clamped when falling down, and the anti-falling baffle is firmer.
Although theoretically, it is only necessary that H/V1 is smaller than T0 and H/V1 is larger than T0, for the consideration of engineering safety and the factors of various parameters in the field such as the spacing between the round steel rungs 2, the elastic modulus of the spring, and the installation error, the actual measurement needs to obtain calculation results far larger or far smaller, that is, the difference is at least 10 times or more.
The limiting mechanism is used for limiting the movement direction of the anti-falling baffle to enable the anti-falling baffle to move in the horizontal direction as much as possible, in the specific embodiment shown in fig. 1 and 5, the limiting mechanism comprises a limiting plate 4 positioned above the horizontal anti-falling baffle 10 and a supporting rod 9 positioned below the horizontal anti-falling baffle 10, the supporting rod 9 and the limiting plate 4 are both fixed on a support, the upper part and the lower part of the horizontal anti-falling baffle 10 are respectively limited by the limiting plate 4 and the supporting rod 9 with a large area, the horizontal movement is achieved, the supporting rod 9 also plays a supporting role for the anti-falling baffle, the tail end of the supporting rod 9 is generally in a circular arc shape to reduce the friction force as much as possible, the limiting plate 4 is fixed on the support, does not depend on the anti-falling baffle to support; a guide screw rod can be further arranged on the support, the first reset spring 8 is sleeved on the guide screw rod to guide the thrust of the first reset spring 8, and the spring is prevented from stretching obliquely.
FIG. 5 is a schematic diagram of peripheral components of an embodiment of the anti-falling device, wherein the anti-falling device comprises a building attachment plate 3, a pair of side guard plates 16 perpendicular to the building attachment plate 3, and a horizontal plate above the side guard plates 16, the horizontal anti-falling baffle 10, a limiting mechanism, a rotating shaft and a bevel plate are all positioned in a space enclosed by the side guard plates 16, the building attachment plate 3 and the horizontal plate, and two sides of one side of the horizontal plate, which is far away from the building attachment plate 3, are respectively provided with a half-embracing hole 17 for a vertical supporting column 1 of a scaffold to pass through; the function of the building flitch 3 is to fix the anti-falling device on the outer vertical surface of the building by utilizing the fixing device on the flitch, such as bolt screw holes and the like, and the specific anti-falling structure is arranged in a semi-closed structure below the limiting plate 4, so that the anti-falling device can be prevented from being polluted by building garbage and the like to influence the performance of each spring and each rotating shaft.
