Description

Technical Field

[0001] The invention relates to the technical field of guide rails for protective platforms, and more specifically, to an aluminum alloy guide rail for a protective platform for building construction. Background Art

[0002] In modern building construction, automatic climbing protection frames are widely used in the construction of high-rise buildings as an efficient vertical transportation and working platform. In order to ensure the safety of construction workers and construction efficiency, climbing frame systems are usually equipped with aluminum alloy rails, which not only provide stable guidance and support, but also integrate a variety of safety devices, such as top supports and fall prevention devices.

[0003] In the prior art, the guide rail is usually provided with two openings arranged front and back. The front opening is used for engaging the top support to provide additional support to prevent the climbing frame from tilting or sliding during the ascent or descent. The rear opening is used for engaging the fixing pin on the anti-fall device to form a reliable engaging point to prevent the platform from accidentally sliding down or falling off. This double opening design not only provides multiple protections, but also improves the operating convenience of construction personnel and the overall safety of the system.

[0004] However, in actual use, as shown in the instruction manual Figure 2 As shown, although the pendulum block of the anti-fall device on the end of the guide rail can be used to perform emergency braking when the protective platform slides down at high speed by using the speed of the pendulum block returning to its original position slower than the falling speed, this design still has shortcomings. Specifically, after the emergency engagement of this single protective structure, the load force is only attached to the guide rail, and the load force cannot be effectively transferred to the wall bracket used to install the guide rail, so as to use the entire wall surface to offset the impact force. In particular, when the fixing pin or locking mechanism fails, it is very likely to cause the entire anti-fall system to fail, posing a greater safety risk. Summary of the invention

[0019] Compared with the prior art, the above technical solution provided by the present invention has at least the following beneficial effects:

[0020] (1) Through the front-to-back alignment design of the first and second snap-fit ​​openings on the guide rail bracket, combined with the extension mechanism and the wall-mounted tightening mechanism in the additional snap-fit ​​mechanism, the device can use the fitting block to clamp the bolts of the wall-mounted bracket through the expansion and contraction of the annular airbag ring during the extension of the extended panel. This ensures a tight connection between the wall-mounted bracket and the extended panel, and enhances the stability of the entire system. In particular, during emergency braking, the load force can be effectively transferred to the wall-mounted bracket, and the entire wall surface can be used to offset the impact force, avoiding the instability problem in the prior art where the load force is only attached to the guide rail.

[0021] (2) Multiple protection measures are adopted to ensure that the anti-fall device is still effective when the fixing pin or locking mechanism fails. When the swing block of the anti-fall structure on the outside extends into the first engaging opening, the adjustable trigger mechanism is triggered, driving the extension mechanism to extend toward the side of the wall-mounted bracket, so that the wall-mounted clamping mechanism clamps the bolts of the wall-mounted bracket. Not only does it provide an extra layer of protection, it also ensures that the anti-fall device can be indirectly connected to the wall-mounted bracket, transferring the high-speed falling force directly to the wall. This design significantly improves the anti-fall safety of the system, reduces the risk of safety accidents, and provides more reliable safety protection for construction personnel.

[0022] (3) Through the automated design, the linkage operation of the extended panel and the wall-mounted tightening mechanism is realized, which does not require manual intervention and is easy to operate. The electric telescopic rod in the adjustable trigger mechanism can adjust the angle of the trigger support block according to the actual situation to ensure that the trigger support block can better contact the inserted pendulum block. In addition, the reset airbag sleeve in the wall-mounted tightening mechanism can transport gas to the annular airbag ring under the squeeze state, causing it to expand and clamp the bolts. In the absence of squeezing force, the reset airbag sleeve will automatically reset, so that the gas in the annular airbag ring is taken out and restored to its original state. This not only improves the reliability of the system, but also enables it to quickly return to normal use after the danger is eliminated, ensuring the continuity and efficiency of the construction process.

[0039] The following is a detailed description of an aluminum alloy guide rail for a protective platform for construction provided by the present invention in conjunction with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are listed as the best and preferred embodiments, and other alternatives can also be used by technicians in some known technical fields; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the present invention.

[0040] like Figures 1 to 8 As shown, an embodiment of the present invention provides an aluminum alloy guide rail for a protective platform for construction, including a guide rail bracket 1, a plurality of first snap-fitting openings 3 are sequentially opened from top to bottom on one side surface of the guide rail bracket 1, and a side of the first snap-fitting opening 3 is used as the front side of the device, and a plurality of second snap-fitting openings 4 are sequentially opened from top to bottom on the rear side of the guide rail bracket 1, and the second snap-fitting openings 4 are aligned with the first snap-fitting openings 3 front to back, and side slide grooves 2 are opened at both left and right sides of the guide rail bracket 1, and fitting rails 5 are opened at both side corners of the guide rail bracket 1, and an additional snap-fitting mechanism 6 is slidably fitted through the fitting rails 5;

[0041] The additional engaging mechanism 6 comprises a U-shaped embedded block 61 and a first reserved opening 64 formed on the outer surface of the U-shaped embedded block 61 and aligned with the first engaging opening 3. The U-shaped embedded block 61 is a U-shaped opening structure as a whole, and its opening end faces the second engaging opening 4. A partition beam frame 65 is fixedly connected to the inner side of the U-shaped embedded block 61. An adjustable trigger mechanism 67 is arranged on the front side of the partition beam frame 65, and an extension mechanism 68 is arranged on the rear side of the partition beam frame 65.

[0042] Among them, the extending mechanism 68 includes a reset spring sleeve 6810 and an extending panel 685 on the reset end of the reset spring sleeve 6810, and the adjustable trigger mechanism 67 is overall similar to an L-shaped flip plate structure, one side of which is clamped on the upper side of the extending panel 685 to fold the extending panel 685, and the anti-fall pendulum block extending into the first locking opening 3 is tilted upward to tilt the adjustable trigger mechanism 67 so that the extending panel 685 is released from the locking state and extends outward, and is sleeved on the wall bracket on one side of the second locking opening 4 for emergency braking.

[0043] In order to solve the problem that the anti-fall device configured on the guide rail of the existing protection platform fails to effectively transfer the load force to the wall bracket during emergency braking, which may cause safety risks, the above-mentioned technical solution is now adopted to solve the problem. The above-mentioned technical solution is mainly composed of a guide rail bracket 1 and an additional clamping mechanism 6. The guide rail bracket 1 is a conventional aluminum alloy guide rail for a protection platform in the prior art, which is used to provide stable guidance and support. The whole is composed of a first clamping opening 3, a second clamping opening 4 and a side slide groove 2, wherein the first clamping opening 3 and the second clamping opening 4 are arranged one after the other, and the first clamping opening 3 is a square opening as a whole, which is used to fit with the swing block of the anti-fall structure on the outside, as shown in the attached manual. Figure 2 As shown. The second engaging opening 4 is used to connect with the wall-mounted bracket. After being connected with the wall-mounted bracket, the bolts on the wall-mounted bracket will extend into the interior of the guide rail bracket 1 because of the opening. The side slide grooves 2 arranged on both sides of the guide rail bracket 1 are used to fit with the pulley of the anti-falling structure on the outside to play a guiding role. The material on one side of the side slide groove 2 is an iron-nickel alloy in the prior art, which not only has high mechanical strength, but also has good magnetic conductivity, which can meet the requirements of magnets attracting each other and moving up and down through metal plates. A corresponding metal coating is provided on the side of the pulley of the anti-falling structure, which corresponds to the adsorption of the electric-controlled magnetic suction block unit 63, so as to drive the additional engaging mechanism 6 on the inner side of the guide rail bracket 1 to be raised and lowered synchronously, so that the additional engaging mechanism 6 can be synchronized to the position of the anti-falling structure on the outside.

[0044] The additional locking mechanism 6 on the outside is composed of a U-shaped embedded block 61, a first reserved opening 64, a partition crossbeam frame 65, an adjustable trigger mechanism 67 and an extension mechanism 68. The U-shaped embedded block 61 is integrally slidably fitted inside the guide rail bracket 1, and the first reserved opening 64 corresponds to the first locking opening 3. When the swing block of the anti-falling structure on the outside extends into the first locking opening 3, it also extends into the first reserved opening 64, so as to trigger the adjustable trigger mechanism 67 to drive the extension mechanism 68 to extend toward one side of the wall-mounted bracket and be sleeved on the bolts of the wall-mounted bracket to unload and transfer the force.

[0045] like Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown, both sides of the U-shaped embedded block 61 are provided with fitting grooves 62 for sliding fitting with the fitting track 5, and both sides of the outer surface of the U-shaped embedded block 61 facing the fitting track 5 are fixedly installed with electric-controlled magnetic suction block units 63, and the adjustable trigger mechanism 67 includes a first hinged sleeve 671 fixedly installed at the middle position of the upper surface of the partition crossbeam frame 65, and both sides of the first hinged sleeve 671 are fixedly installed with torsion spring sleeves 672, and the first hinged sleeve 671 is internally movably installed with an axle sleeve 673 connected to the torsion end of the torsion spring sleeve 672, and the outer surface of the axle sleeve 673 is fixedly connected with a flip bracket 674, and the flip bracket 674 always has a tendency to rotate counterclockwise under the torsion force of the torsion spring sleeve 672, and the inner side of the first hinged sleeve 671 is also fixedly installed with a stopper 678 blocking the bottom of the flip bracket 674, so that the flip bracket 674 is in a 180-degree horizontal arrangement state.

[0046] Among them, the configured fitting groove 62 fits with the fitting track 5 inside the guide rail bracket 1. After the electrically controlled magnetic block units 63 on both sides of the U-shaped embedded block 61 are adsorbed and correspond to the pulleys on the outside of the side slide groove 2, a guiding function can be provided. The electrically controlled magnetic block unit 63 is an electrically controlled magnetic block unit 63 structure in the prior art that can continue to control the magnetic state through electric energy. It also includes a coil winding, using an electromagnet. By energizing the coil, a magnetic field can be generated, thereby activating or changing the magnetic state of the magnetic material to control the magnetic state. The torsion spring sleeves 672 installed on both sides of the first hinge sleeve 671 use the torsion force of their torsion springs to make the inner shaft sleeve 673 have the force to rotate counterclockwise, and the stopper 678 arranged at the bottom of the first hinge sleeve 671 is used to resist the flip bracket 674 that is to be rotated counterclockwise, so that the flip bracket 674 cannot be further rotated counterclockwise and can only be docked in a 180-degree horizontal arrangement state, and can only be rotated clockwise. When the pendulum block of the outer anti-falling structure extends into the interior of the first engaging opening 3, it will also extend into the first reserved opening 64, and can push up the flip bracket 674 to trigger the adjustable trigger mechanism 67 to drive the extension mechanism 68 to extend toward the side of the wall-mounted bracket.

[0047] like Figure 1 , Figure 3 , Figure 4 , Figure 5As shown, the flip bracket 674 is fixedly connected to a Y-shaped sleeve 677 on one side facing the first reserved opening 64, and a trigger support block 679 is movably hinged inside the outer opening end of the Y-shaped sleeve 677. A second hinged sleeve 6710 is fixedly installed on the surface on one side of the inner angle between the trigger support block 679 and the Y-shaped sleeve 677, and an electric telescopic rod 6711 is movably hinged between the two second hinged sleeves 6710, and the protruding end of the trigger support block 679 is a semicircular structure.

[0048] Among them, the configured Y-shaped sleeve 677 is for hingedly contacting the trigger support block 679, and the protruding end of the trigger support block 679 is a semicircular structure, which is more convenient for contacting the inserted pendulum block, and the configured electric telescopic rod 6711 is a telescopic rod structure that can be controlled according to needs in the prior art. The outward tilt angle of the trigger support block 679 can be adjusted according to actual conditions, so that it can be arranged inside the U-shaped embedded block 61 with a better triggering position.

[0049] like Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown, the side of the flip bracket 674 facing the opening of the U-shaped embedded block 61 is composed of two fork plate structures that extend outward in a flush manner, and a bearing sleeve 675 is fixedly installed on one end of the extension, and a roller 676 is fixedly installed on the movable end inside the two bearing sleeves 675, and a friction coating is fixedly installed on the outer surface of the roller 676. A remote camera unit 66 is fixedly installed on the side wall of the U-shaped embedded block 61 on one side of the trigger support block 679, and the camera end of the remote camera unit 66 is aligned with the trigger support block 679.

[0050] The configured bearing sleeve 675 is a bearing sleeve ring structure in the prior art, which enables the roller 676 to have a better rolling effect, and the friction coating fixedly installed on the outer surface of the roller 676 is a coating with high hardness, good wear resistance and low friction coefficient in the prior art, such as titanium nitride coating. The configured remote camera unit 66 is a module in the prior art that can transmit the shooting content in real time, and can output the state of the internal trigger support block 679 in real time, which can not only make the trigger support block 679 better adjusted to a suitable angle, but also can know the internal engagement status in real time.

[0051] like Figure 1 , Figure 3 , Figure 4 , Figure 5As shown, the extension mechanism 68 includes a first cylindrical sleeve 681 fixedly installed at the axial position of the rear side of the partition crossbeam frame 65, the first cylindrical sleeve 681 is flush with the axial center of the first reserved opening 64 front and back, a plurality of telescopic slide grooves 682 are sequentially opened on the inner circle of the first cylindrical sleeve 681, a second cylindrical sleeve 683 is inserted and installed inside the first cylindrical sleeve 681, and a plurality of limiting protrusions 684 are sequentially fixedly connected on one side end of the outer surface of the second cylindrical sleeve 683, the limiting protrusions 684 are engaged with the telescopic slide grooves 682, and an extension panel 685 is fixedly installed on the side of the outer surface of the second cylindrical sleeve 683 away from the limiting protrusions 684.

[0052] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, an extension bracket 687 is fixedly installed at the middle position of the upper side of the extended panel 685, an inclined guide frame 688 is fixedly installed on the side of the extension bracket 687, the roller 676 is slidably sleeved on the bottom of the inclined edge of the inclined guide frame 688, and a friction coating is fixedly installed on the inclined edge surface where the inclined guide frame 688 contacts the roller 676.

[0053] Among them, the configured roller 676 is slidably sleeved on the bottom of the oblique side of the oblique guide frame 688. At one end of the roller 676, that is, when the flip bracket 674 does not rotate and remains horizontal, it will be sleeved at the topmost position of the oblique guide frame 688. If the flip bracket 674 is lifted up, it will rotate clockwise, that is, lift up, so that the roller 676 moves synchronously along the oblique guide frame 688, and the extended panel 685 is slowly extended outward. Therefore, after the flip bracket 674 is quickly lifted up, its extended panel 685 will be synchronously extended outward immediately.

[0054] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the extension mechanism 68 also includes a U-shaped limit frame 689 fixedly connected to the two side ends of the rear side of the partition beam frame 65, and the two side edges of the extended panel 685 are fixedly connected with L-shaped bending plates 686, and the upper and lower side ends of the L-shaped bending plates 686 are provided with openings corresponding to the U-shaped limit frame 689, and the two support rods located on the U-shaped limit frame 689 are fixedly installed with reset spring sleeves 6810 corresponding to the L-shaped bending plates 686. Under the elastic reset action of the reset spring sleeves 6810 on the four sides, the extended panel 685 always has a tendency to extend toward the second engaging opening 4.

[0055] Among them, the configured U-shaped limit frame 689 is U-shaped as a whole, and is sleeved on the rear side of the partition beam frame 65, and is used to slide and cover the protruding panel 685, and the configured reset spring sleeve 6810 is arranged on the inner side of the protruding panel 685, so that the protruding panel 685 has a tendency to be ejected outward, and its elastic capacity is lower than the torsional force of the torsion spring sleeve 672 on both sides of the first hinge sleeve 671. Under the torsional force of the torsion spring sleeve 672, it can cover the protruding panel 685.

[0056] The specific working principle of the additional locking mechanism 6 is as follows:

[0057] First, the guide rail bracket 1 is connected to the wall bracket on the wall through the second snap-fit ​​opening 4, and the guide rail bracket 1 is installed and fixed on the outer wall of the building, providing a guide rail that can be raised and lowered for the external protection platform. In order to make the up and down movement more stable and safe, an anti-fall structure will be configured on the external protection platform, and the anti-fall pendulum block of the anti-fall structure will be stuck in the first snap-fit ​​opening 3 of the guide rail bracket 1, and the anti-fall pendulum block in the prior art is as shown in the attached manual. Figure 2 As shown, it can be divided into an upper swing block and a lower swing block. The lower swing block will be inserted into the first engaging opening 3 in sequence during the normal up and down movement of the platform. Since it is equipped with a spring, it can be withdrawn after each insertion, and it reciprocates in sequence. When the platform is moving up and down at high speed, that is, in the event of an accident, the high-speed up and down movement speed of the platform is higher than the withdrawal speed of the lower swing block. At this time, the upper swing block will be stuck in the first engaging opening 3 of the guide rail bracket 1, that is, the swing block extends into the interior of the first engaging opening 3;

[0058] Then, when it extends into the interior of the first engaging opening 3, it will push up the trigger support block 679, causing the trigger support block 679 to tilt upward, that is, to rotate clockwise around the hinged end of the first hinge sleeve 671. Since the Y-shaped sleeve 677 and the flip bracket 674 are integrated, during the process of the trigger support block 679 tilting upward, the flip bracket 674 will rotate downward, causing the roller 676 pressed against the bottom of the inclined guide frame 688 to move downward synchronously. Under the reset action of the four-side reset spring sleeve 6810, the roller 676 moves downward and the outward panel 685 will extend outward, causing the outward panel 685 to extend toward the second engaging opening 4. The second engaging opening 4 is at the bolt position of the wall bracket. Therefore, the outward panel 685 will extend toward the bolt position of the wall bracket synchronously after the flip bracket 674 is triggered.

[0059] Among them, the specific process of the protruding panel 685 extending outward is as follows: since the first cylindrical sleeve 681 is fixedly installed on the rear side of the partition beam frame 65, its outer surface is sleeved with the second cylindrical sleeve 683 through the sliding relationship between the telescopic slide groove 682 and the limiting protrusion 684. In the process of the reset spring sleeve 6810 being pushed outward, the second cylindrical sleeve 683 will extend outward, driving the protruding panel 685 to extend outward along the U-shaped limiting frame 689.

[0060] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, a wall-mounted tightening mechanism 7 corresponding to the wall-mounted bracket bolt inserted from the second engaging opening 4 is also arranged at the axial position of the surface of the extended panel 685 on the side facing the second engaging opening 4, and the wall-mounted tightening mechanism 7 includes a third cylindrical sleeve 71, and a buffer circular ring rubber sleeve 73 is fixedly installed inside the third cylindrical sleeve 71, and a circular ring airbag ring 75 is fixedly installed on the inner ring of the buffer circular ring rubber sleeve 73, and two second air ducts 74 separated by 180 degrees are fixedly installed on the outer circular ring edge of the buffer circular ring rubber sleeve 73, and the second air duct 74 is connected to the circular airbag ring 75.

[0061] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, two second reserved openings 72 for the second gas delivery conduit 74 to pass through are fixedly installed on the outer annular edge of the third cylindrical sleeve 71, and a plurality of fitting blocks 76 are fixedly installed in sequence on the annular surface of the annular airbag ring 75.

[0062] Among them, the several fitting blocks 76 which are fixedly installed in sequence are metal sleeve blocks, which are used to increase the clamping force of the clamping end of the annular airbag ring 75 in the inflated state, and the annular airbag ring 75 is a high-strength rubber airbag in the prior art.

[0063] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the wall-mounting and tightening mechanism 7 also includes a reset airbag sleeve 6811 fixedly mounted on the inner side of the U-shaped limit frame 689 on each side, and a first air supply duct 6812 is fixedly mounted on the side of the reset airbag sleeve 6811, and the first air supply duct 6812 is connected and corresponds to the second air supply duct 74.

[0064] Among them, the configured reset airbag sleeve 6811 is an airbag structure that can be reset in the prior art. In the squeezed state, the gas stored inside will enter the interior of the annular airbag ring 75 along the first air duct 6812 and the second air duct 74, causing the annular airbag ring 75 to expand. In the absence of squeezing force, the reset airbag sleeve 6811 will automatically reset, and the automatic reset of the reset airbag sleeve 6811 will generate negative pressure, which will cause the gas stored in the annular airbag ring 75 to be taken out again.

[0065] The specific working principle of the configured wall-attaching and tightening mechanism 7 is as follows:

[0066] During the process of the protruding panel 685 extending outward, the wall-mounted tightening mechanism 7 on its outer side surface will contact the bolts of the wall-mounted bracket, that is, the third cylindrical sleeve 71 will contact the bolts of the wall-mounted bracket, and during the process of the protruding panel 685 extending outward, the L-shaped bending plates 686 on both sides of the protruding panel 685 will approach the U-shaped limit frame 689, squeezing the reset airbag sleeves 6811 on both sides of the U-shaped limit frame 689, so that the gas in the reset airbag sleeve 6811 enters the annular airbag ring 75 along the first air supply duct 6812 and the second air supply duct 74, causing the annular airbag ring 75 to expand. As the extended panel 685 gradually approaches the U-shaped limit frame 689, its annular airbag ring 75 also gradually shrinks, and the fitting block 76 is used to tighten the bolts. After clamping, its wall-mounted bracket is tightly fastened to the wall-mounted tightening mechanism 7, and the wall-mounted tightening mechanism 7 is engaged with the anti-falling pendulum block on the outside of the guide rail bracket 1 due to the additional locking mechanism 6, so that the anti-falling device is indirectly connected to the wall-mounted bracket, and the high-speed descending force is directly transferred to the wall. It not only provides an extra layer of protection, but also ensures that the anti-falling device is still effective when the fixing pin or locking mechanism fails, thereby significantly improving the anti-falling safety of the system.

[0067] And, further, the trigger end adjustable trigger mechanism 67 used for its additional locking mechanism 6 can control the trigger state of its trigger support block 679 through the electric telescopic rod 6711. After the danger is eliminated, the trigger support block 679 can be controlled to tilt through the electric telescopic rod 6711 to break away from the state of being lifted by the swing block, and the flip bracket 674 can be restored to a horizontal state. The wall-mounted tightening mechanism 7 can also be retracted to automatically release the fixed state with the wall-mounted bracket, so that the protective platform can be quickly restored to a normal use state. Moreover, since the state of the additional locking mechanism 6 is fitted inside the guide rail bracket 1, multiple ones can be fitted according to needs to provide multiple emergency fixing points, thereby further improving the protection performance and safety performance.
