Specific Embodiment

[0034] To describe in detail the technical content, achieved purpose and effect of the present invention, the following is described in conjunction with the embodiments and with reference to the drawings.

[0035] Refer to the attached Figures 1 to 7 , a guide rail of an attached lifting protection platform of the present invention, the guide rail is an aluminum alloy guide rail, the guide rail includes two U-shaped channel steel imitation parts 1 with opposite opening directions and a connecting plate 2 fixedly connected between the two channel steel imitation parts 1, and the channel steel imitation parts 1 and the connecting plate 2 are integrally arranged;

[0036] The channel steel imitation part 1 includes two parallel flange plates and a web plate fixedly connected between the two flange plates;

[0037] There are two connecting plates 2 which are arranged in parallel with each other. The side edges of the connecting plates 2 are fixedly connected to the connection parts of the flange plates and the web plate of the channel steel imitation part 1, and the connecting plates 2 and the flange plates of the channel steel imitation part 1 are in the same plane;

[0038] A plurality of anti-falling holes 3 with equal spacing are formed in the surface of one of the connecting plates 2, a cross bar 31 is arranged between adjacent anti-falling holes 3, and a plurality of connecting holes 4 with equal spacing are formed in the surface of the other connecting plate 2.

[0039] The working principle of the present invention is as follows: The cross-sectional shape of the channel steel imitation part 1 of the aluminum alloy guide rail is similar to the cross-sectional shape of the channel steel. When the climbing frame climbs on the guide rail, the channel steel imitation part 1 can play a role in guiding and preventing inclination. The connecting plate 2 provided with the anti-falling holes 3 contacts with the external anti-falling guide seat. When the guide rail falls rapidly during the ascending process, the anti-falling device will be stuck in the anti-falling holes 3, so as to fix the guide rail and avoid the direct fall of the guide rail.

[0040] It can be seen from the above description that the beneficial effects of the present invention are as follows: The guide rail made of aluminum alloy can greatly reduce the weight, thereby improving the construction efficiency; the aluminum alloy guide rail is integrally formed, and welding is not required between each part, and the production precision and strength are relatively high; the anti-falling holes can ensure that the guide rail will be stuck by the anti-falling device when falling, so as to avoid the danger caused by the direct fall of the guide rail.

[0041] Furthermore, a deep hole is formed in the web plate of the channel steel imitation part 1 along the length direction of the guide rail, a removable steel wire 12 is arranged in the deep hole, and the hardness of the steel wire 12 is greater than that of the guide rail.

[0042] It can be seen from the above description that the steel wire and the deep hole are in clearance fit. Under normal circumstances, the staff can relatively easily take out the steel wire from the deep hole. When the guide rail undergoes a slight deformation, because the steel wire has a greater hardness and is not easily deformed along with the guide rail, the steel wire will be stuck in the deep hole and cannot be taken out. In this way, it can be quickly judged whether the guide rail has deformed, thereby improving the use safety of the guide rail.

[0043] Furthermore, the anti-falling holes 3 are square holes.

[0044] It can be seen from the above description that the square holes can make the surface contact with the anti-falling device, which is beneficial to reducing the anti-falling shear force and further improving the reliability of the anti-falling device.

[0045] Furthermore, the connecting holes 4 are round holes.

[0046] Further, the anti-falling holes 3 and the connecting holes 4 correspond to each other one by one.

[0047] Further, a plurality of equally spaced transverse grooves 11 are formed on the surface of the imitation channel steel part 1.

[0048] As can be seen from the above description, the transverse grooves can facilitate greater friction when the rollers on the external platform roll on the surface of the guide rail.

[0049] Further, the guide rail is prepared from the following guide rail raw materials in parts by mass: 0.1 part of copper, 0.7 - 1.3 parts of silicon, 0.5 part of iron, 0.4 - 1.0 parts of manganese, 0.6 - 1.2 parts of magnesium, 0.2 part of zinc, 0.25 part of chromium, 0.1 part of titanium, and 95.35 - 97.15 parts of aluminum.

[0050] As can be seen from the above description, the aluminum alloy guide rail processed from the above raw materials not only has a light weight, but also has a better overall structural strength than the steel guide rail, and has the characteristics of corrosion resistance, thus greatly extending its service life.

[0051] An attached lifting and protective platform includes an anti-falling device and the above-mentioned guide rail;

[0052] The guide rail can move up and down on the anti-falling device;

[0053] The anti-falling device includes a support 5, a trigger pendulum 6, and an anti-falling pendulum 7;

[0054] The anti-falling pendulum 7 includes a lightweight part 71 and a heavy part 72 which are integrally arranged, and the center of gravity of the anti-falling pendulum 7 is located in the heavy part 72;

[0055] The trigger pendulum 6 and the lightweight part 71 of the anti-falling pendulum 7 are rotationally connected to the support 5 through the same rotating shaft;

[0056] The support 5 is internally provided with a lower baffle 8 and an anti-falling baffle 9 for limiting the rotation range of the anti-falling pendulum 7 relative to the support 5 within 0 - 90 degrees. The lower baffle 8 is located in the direction of the counterclockwise rotation of the heavy part 72 around the rotating shaft, and the anti-falling baffle 9 is located in the direction of the clockwise rotation of the heavy part 72 around the rotating shaft;

[0057] The lightweight part 71 is provided with an L-shaped limiting surface 73 for limiting the rotation range of the trigger pendulum 6 relative to the support 5 within 0 - 90 degrees;

[0058] The trigger pendulum 6 is in contact with the cross bar 31 or located in the anti-falling hole 3, and when the anti-falling pendulum 7 rotates to 90 degrees, it is clamped in the anti-falling hole 3.

[0059] As can be seen from the above description, the anti-falling device includes the following four states: a stationary state (such as Figure 4 ) and a rising state (such asFigure 5 ), the descending state (such as Figure 6 ) and the falling and jamming state (such as Figure 7 ).

[0060] Such as Figure 4 , in the static state, the external guide rail, the trigger pendulum block 6 and the anti-falling pendulum block 7 all remain stationary. Among them, the anti-falling pendulum block 7 remains vertical under the action of its own gravity, while the end of the trigger pendulum block 6 away from the rotating shaft opens outward and is located outside the support 5.

[0061] Such as Figure 5 , in the ascending state, the external guide rail moves upward under the action of the lifting power. When the trigger pendulum block 6 touches the crossbar 31 on the guide rail, the crossbar 31 will push the trigger pendulum block 6 to rotate counterclockwise around the rotating shaft, while the anti-falling pendulum block 7 remains stationary; when the trigger pendulum block 6 moves into the anti-falling hole 3 between the crossbars 31, since the trigger pendulum block 6 is separated from the crossbar 31, the trigger pendulum block 6 rotates clockwise and resets under the action of its own weight and falls into the anti-falling hole 3; as the external guide rail continues to move upward, when the trigger pendulum block 6 touches the crossbar 31 on the guide rail, the crossbar 31 will push the trigger pendulum block 6 to rotate counterclockwise around the rotating shaft again, and so on.

[0062] Such as Figure 6 , in the descending state, the external guide rail moves slowly downward under the action of the lifting power. When the trigger pendulum block 6 touches the position of the crossbar 31, the surface of the crossbar 31 contacts the end of the trigger pendulum block 6, and the crossbar 31 pushes the trigger pendulum block 6 to rotate clockwise. At the same time, the end of the trigger pendulum block 6 also moves relative to the surface of the descending crossbar 31. When the trigger pendulum block 6 rotates to contact the bottom end of the L-shaped limiting surface 73 of the light part 71, the trigger pendulum block 6 cannot continue to rotate relative to the anti-falling pendulum block 7, so it will drive the anti-falling pendulum block 7 to rotate clockwise together until the trigger pendulum block 6 touches the top end of the lower baffle 8 and cannot continue to rotate. As the external guide rail continues to move downward, when the crossbar 31 moves to not contact the trigger pendulum block 6, that is, when the trigger pendulum block 6 falls into the anti-falling hole 3, the anti-falling pendulum block 7 quickly returns to the stationary state under its own gravity.

[0063] Such as Figure 7In the falling blocking state, when the protection platform loses its supporting force and lifting force, the protection platform 4 and the guide rail drop rapidly, triggering the pendulum block 6 to disengage from the crosspiece 31 of the guide rail and enter the anti-falling hole 3. Since the guide rail descends at a speed much faster than the anti-falling pendulum block 7 resets, the time it takes for a crosspiece 31 on the guide rail to drop to the upper end of the anti-falling pendulum block 7 is less than the reset time of the anti-falling pendulum block 7. The anti-falling pendulum block 7 has no time to reset quickly and is impacted downward by the previous crosspiece 31. It is also blocked by the anti-falling baffle 9 and the crosspiece 31 of the guide rail through the rotating shaft as a fulcrum to form a lever. The anti-falling pendulum block 7 is stuck in the anti-falling hole 3, and the guide rail is stuck and cannot drop, thereby preventing the protection platform and the guide rail from falling.

[0064] The support of the above-mentioned anti-fall device itself can provide support and connection between the guide rail and the wall when it is stationary; the anti-fall pendulum block and the trigger pendulum block will not affect the operation of the guide rail when the guide rail rises or descends normally; when the guide rail falls rapidly, the anti-fall pendulum block will rotate to a parallel state to form a lever jam and cannot be reset in time, so it will engage with the guide rail, thereby preventing the guide rail from continuing to fall.

[0065] Furthermore, a support member 61 is fixedly connected to a surface of the trigger pendulum block 6 that is opposite to the L-shaped limiting surface 73 and is at one end away from the rotation axis.

[0066] From the above description, it can be seen that when the anti-fall pendulum block is in the state of falling and blocking, the trigger pendulum block is held against the lower baffle, and the top of the support member will hold against the lightweight part, so that the force borne by the lightweight part can be transmitted to the lower baffle through the support member, avoiding the lightweight part from being deformed due to excessive impact, thereby further improving stability.

[0084] A guide rail of an attached lifting protection platform similar to that in Example One, the difference being that the guide rail comprises raw materials with the following mass percentages: 0.1% copper, 1.0% silicon, 0.5% iron, 0.6% manganese, 0.8% magnesium, 0.2% zinc, 0.25% chromium, 0.1% titanium and 96.45% aluminum.

[0085] Example Four

[0086] Please refer to Figures 4 to 7 , a falling prevention system for an attached lifting protection platform, comprising a falling prevention device and a guide rail as described in any one of Embodiments 1 to 3;

[0087] The guide rail moves up and down on the falling prevention device through an external power system;

[0088] The falling prevention device includes a support 5, a trigger pendulum block 6 and a falling prevention pendulum block 7;

[0089] The falling prevention pendulum block 7 includes a lightweight part 71 and a heavy part 72 which are integrally arranged, and the center of gravity of the falling prevention pendulum block 7 is located in the heavy part 72;

[0090] The trigger pendulum block 6 and the lightweight part 71 of the falling prevention pendulum block 7 are rotationally connected to the support 5 through the same rotating shaft;

[0091] A lower baffle 8 and a falling prevention baffle 9 for restricting the rotation range of the falling prevention pendulum block 7 relative to the support 5 within 0 to 90 degrees are provided inside the support 5. The lower baffle 8 is located in the counterclockwise rotation direction of the heavy part 72 around the rotating shaft, and the falling prevention baffle 9 is located in the clockwise rotation direction of the heavy part 72 around the rotating shaft;

[0094] In summary, the beneficial effects provided by the present invention are as follows: The guide rail made of aluminum alloy can greatly reduce the weight, thereby improving the construction efficiency; the aluminum alloy guide rail is integrally formed, and welding is not required between each part, and the production accuracy and strength are relatively high; the falling prevention hole can ensure that the guide rail will be caught by the falling prevention device when falling, thereby avoiding the danger of the direct fall of the guide rail. The square hole can make the contact between it and the falling prevention device a surface contact, which is beneficial to reducing the falling prevention shear force and further improving the reliability of the falling prevention device. The transverse groove can facilitate the rollers on the external platform to have greater friction when rolling on the surface of the guide rail. The wire and the deep hole are in clearance fit. Under normal circumstances, the staff can relatively easily take out the wire from the deep hole. When the guide rail undergoes slight deformation, because the wire is harder and not easily deformed along with the guide rail, the wire will be stuck in the deep hole and cannot be taken out.

When the anti-fall pendulum block is in a state of falling blocking, the trigger pendulum block is held against the lower baffle, and the top of the support member will hold against the light part, so that the force on the light part can be transmitted to the lower baffle through the support member, preventing the light part from being deformed due to excessive impact, and further improving stability.

[0096] The aluminum alloy guide rails made from the above raw materials are not only light in weight, but also have better overall structural strength than steel guide rails, and are corrosion-resistant, which greatly extends their service life. The T6 heat treatment process is a state of artificial aging after solution heat treatment. The aluminum alloy profiles that have undergone T6 heat treatment can ensure that they have the highest strength and can be used in high-load conditions.

[0097] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention.
