[0002] With the rapid development of the construction industry, the demand for the construction of high-rise and super-high-rise buildings is increasing. As an indispensable temporary structure in construction, the safety of scaffolding during its erection and dismantling is particularly important.

[0003] The Chinese utility model patent with patent application number CN201420562991.8 discloses a scaffolding safety construction device, including a rod body, a positioning mechanism, a tensioner and a rope, and the specific structure is as follows. A positioning mechanism is provided on one side of the rod body, and the positioning mechanism is provided with a hook fixed on the outside of the rod body, and an arc-shaped clamping part is also provided on the outside of the rod body adjacent to the hook, and an engaging groove is provided on the outside of the clamping part, and a clamping body is provided on the other side of the clamping part, and the clamping body is used to movably engage with the engaging groove of the clamping part; a plurality of tensioners are provided on the other side of the rod body relative to the positioning mechanism, and the tensioners are provided with a body, and a channel is provided inside the body, and one side of the channel is open and provided with a movable clamping body, and one side of the clamping body is provided with a ring handle, and the channel inside the body is used to allow the rope to pass through, and the clamping body is controlled by the handle to press the rope in the channel of the body, so that the rope can be movably passed through the channel inside the tensioner body.

[0015] In one embodiment of the present invention, the safety lock includes a first steel bar and a second steel bar intersecting with the bottom end of the lock hole, and a third spring welded to the first steel bar and the second steel bar away from the hole end.

[0016] In one embodiment of the present invention, a plurality of first springs are provided, which are respectively arranged on the inner wall of the vertical rod tension unit.

If the specific posture changes, the directional indication will also change accordingly.

[0044] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0045] In this patent, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of more restrictions, the elements defined by the sentence "includes..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0046] Depend on Figure 1-7 It can be seen that the embodiment of the present invention provides a safety rope synchronous lifting device for scaffold erection and dismantling, comprising a scaffold 1, a safety rope 2, a pole tension unit 3 provided on the scaffold pole, a safety rope automatic retracting unit 4 provided on the pole tension unit 3, and a safety lock 5. The scaffold 1 comprises a plurality of horizontal poles and vertical poles, thereby forming an overall frame structure, which plays a supporting role; the safety rope 2 is used to provide safety protection for workers during the erection or dismantling of the scaffold, to prevent workers from being injured due to accidental falls. The pole tension unit 3 is provided on the vertical pole of the scaffold. In the process of lifting and lowering the safety rope 2, the pole tension unit 3 may play a role in assisting in fixing or adjusting the path of the safety rope, ensuring that the safety rope can be automatically raised and lowered smoothly with the change of the scaffold height. One end of the safety rope automatic retracting unit 4 is connected to the pole tensioning unit 3, and the other end is connected to the safety rope 2. When the safety rope 2 needs to be installed, one side of the safety rope automatic retracting unit 4 is pulled outward to release the safety rope 2, keeping the safety rope always tight and neither too loose nor too tight, thereby ensuring the safety of the workers. Even when the height of the scaffold changes, the safety rope automatically adjusts its length to keep it tight. The safety lock 5 is used to ensure the reliability and stability of the connection between the safety rope 2 and the workers.

[0047] Depend on Figure 2-3It can be seen that the upright pole tension unit 3 includes a force-bearing arm 32, a first spring 31 welded to the top of the force-bearing arm 32, an anti-slip plate 33 welded to the force-bearing arm, a rubber strip 34 provided on the anti-slip plate 33 and in direct contact with the scaffolding upright pole, a connecting hole 38 provided on the upright pole tension unit 3, a handle 35 one end of which is connected to the upright pole tension unit 3 through the connecting hole 38, a horizontal safety plate 36 connected to the other end of the handle 35, and a safety fixing ring 37 welded to the outer bottom end of the horizontal safety plate 36.

[0048] There are four first springs 31, which are respectively arranged in four directions of the inner wall of the vertical pole tension unit. The force arm 32 is welded to the middle position of the inner wall of the vertical pole tension unit 3, and an anti-skid plate 33 is welded on the top of the force arm 32. A rubber strip 34 is installed on the anti-skid plate 33 to increase the contact area and friction between the force arm 32 and the vertical pole, effectively preventing sliding and ensuring the stability and safety of the vertical pole during the adjustment process. At the same time, the first spring 31 and the force arm 32 are horizontally connected to the top of the inner side.

[0049] The handle 35 is installed into the hole reserved in the vertical pole tension unit 3 by means of a plug-in connection, an anti-slip plate 33 is welded to the top of the lower end of the handle 35, a rubber strip 34 is installed on the anti-slip plate 33 to increase the friction between the force-bearing arm 32 and the vertical pole, and the top of the lower end of the handle 35 is horizontally welded to the first spring 31. By pressing the handle 35, the first spring 31 can be moved horizontally, thereby realizing the adjustment of the tightness of the vertical pole tension unit (3).

[0050] The horizontal safety plate 36 is provided with a reserved groove 361, and a safety fixing ring 37 is welded to the outer bottom end of the groove 361. When the length of the safety rope 2 erected horizontally on the scaffold exceeds the conventional requirements, the safety fixing ring 37 can be used to conveniently fix the excessively long safety rope 2 and effectively tighten it, thereby ensuring that the safety performance during the construction process is not affected and providing a stable and reliable working environment for the operators.

[0051] It can be known that two holes are reserved on the outer side of the groove 361 for the elastic pin to extend into and fix the automatic retracting and releasing unit 4 of the safety rope.

[0052] Depend on Figure 4-5 It can be seen that the safety rope automatic retracting and releasing unit 4 is divided into a first space and a second space. The first space includes a ratchet main shaft 41 disposed in the middle position thereof, a ratchet 43 fixed to the safety rope automatic retracting and releasing unit 4 through the ratchet main shaft 41, a coil spring 42 disposed on the ratchet main shaft 41, and a double stop shaft 45 disposed on the lower side of the ratchet 43;

[0053] The ratchet main shaft 41 bears the main load of the rotational motion, and also ensures smooth and accurate rotation through precise bearing design. The coil spring 42 is wound and installed on the ratchet main shaft 41. When the safety rope is stretched and released, the coil spring gradually accumulates energy; and when recovery is required, the coil spring releases energy, driving the ratchet and the safety rope to rotate in the opposite direction, thereby achieving rapid recovery.

[0054] The safety rope 2 is pulled out of the device through the double stop shaft 45. The worker moves along the horizontal rod of the scaffold to pull out the safety rope 2 for erection. When the worker pulls the safety rope 2 with force, the double stop shaft 45, under the force of the safety rope 2 and the tension spring, will hook the ratchet 43 at the tip to make the ratchet 43 clamp the safety rope 2 and tighten it, thus playing a protective role. The double stop shaft 45 is a safety locking mechanism to prevent the safety rope from being accidentally released quickly under certain circumstances. The setting of the double stop shaft 45 increases the redundancy and reliability of the system, ensuring that the safety rope 2 can be effectively locked in any emergency situation to protect the safety of the user.

[0055] The second space includes a fixing member 46 welded at the middle position thereof, a hole is provided at the top of the fixing member 46, and a second spring 47 is welded at the bottom of the hole;

[0056] The second space further includes an elastic pin 49 and a hanging plate 48 which are arranged in the hole and welded to the second spring 47 .

[0057] The elastic pin 49 and the hanging plate 48 are used to fix the safety rope automatic retracting and releasing unit 4 to prevent the safety rope automatic retracting and releasing unit 4 from being moved horizontally or vertically by external force. The elastic pin extends into the reserved hole of the groove, and the hanging plate is buckled on the outside of the groove.

[0058] In one embodiment of the present invention, by setting up an automatic safety rope retracting and releasing unit 4, the safety rope 2 can be automatically retracted and released as needed, and the length can be adjusted conveniently. The speed difference anti-falling principle is adopted to ensure that the safety rope 2 is taut, and high hanging and low use are achieved to ensure the safety of the operators. This unit and the vertical pole tensioning unit 3 are connected by a pin type, and an elastic pin 49 and a hanging plate 48 are provided to prevent the automatic safety rope retracting and releasing unit 4 from being subjected to external force and causing horizontal or vertical movement.

[0059] The safety lock buckle 5 includes a first steel bar 51 and a second steel bar 52 intersecting the bottom end of the lock hole, and a third spring 53 welded to the first steel bar 51 and the second steel bar 52 away from the hole end.

[0060] The first steel bar and the second steel bar are arranged in parallel, the first steel bar is longer than the second steel bar, one end of the first steel bar is fixed to the safety lock, and the other end is movably connected to the safety lock hole, and the second steel bar is shorter and fixed to one side of the first steel bar.

[0061] The third spring 53, as a key component connecting the first steel bar 51 and the second steel bar 52 away from the hole end, is made of a highly elastic and corrosion-resistant alloy spring material. The setting of the third spring 53 provides the necessary resilience, so that it can quickly return to its original state after unlocking.

[0062] In one embodiment of the present invention, by using the safety lock buckle 5 and the safety rope 2 as a set, the workers are allowed to move freely between scaffolds, and the safety lock buckle 5 can slide flexibly on the safety rope 2. Once encountering the vertical pole tension unit 3, there is no need to tediously unfasten and re-fasten the safety lock buckle 5, and the obstacle can be easily crossed, ensuring the continuous protection state of the workers and seamlessly connecting each step of the operation; at the same time, the safety lock buckle 5 has an automatic reset function, and the steel bar on the safety lock buckle 5 can be automatically reset after touching the horizontal safety plate, which not only simplifies the operation process of passing the safety rope support point and avoids the tediousness of repeated fastening, but also invisibly speeds up the operation rhythm and significantly improves work efficiency. In addition, the automatic reset function also ensures that the safety lock buckle can always respond quickly when the workers are moving quickly or in an emergency.

[0063] In another embodiment of the present invention, a construction method of a safety rope synchronous lifting device for scaffold erection and dismantling is provided, and the specific steps include:

[0064] S100: Device assembly: Process parts according to the patent drawings and assemble them to form a rod elastic unit 3 and a safety rope free retractable unit 4.

[0065] S200: Device installation: Install the vertical pole tension unit 3 on the vertical pole, and move it upward along the vertical pole to the specified position, weld the horizontal safety plate 36 on the horizontal pole, and install the safety rope free retraction unit 4 on the horizontal safety plate 36, and connect the safety rope to the safety rope free retraction unit 4.

[0066] S300: Setting up the safety rope: Pull out the safety rope from the safety rope free retracting unit 4, and set the length of the safety rope as required. If a longer safety rope needs to be set up, the safety rope can be put into the safety fixing ring 37 at the next safety rope node to tighten the safety rope.

[0067] S400: Scaffolding removal: After the operation is completed, the safety rope in the safety rope free retracting unit 4 is retracted, and the device is removed and recycled.

[0068] Specifically, two connection holes 38 are provided on one side of the vertical pole tension unit 3 to facilitate the installation of the handle. Four first springs 31 are welded on the four directions of the inner wall of the vertical pole tension unit 3. The force arm 32 is welded to the middle position of the inner wall of the vertical pole tension unit 3. The anti-slip plate 33 is welded on the top of the force arm 32. The rubber strip 34 is installed on the anti-slip plate 33. The first spring 31 is horizontally connected to the top of the inner side of the force arm 32. Repeat the above operation and weld another one at an adjacent position. The handle 35 is installed in the connection hole 38 reserved for the vertical pole tension unit 3. The anti-slip plate 33 is welded on the top of the lower end of the handle 35 by a pin connection. The rubber strip 34 is installed on the anti-slip plate 33. The lower end of the handle 35 is horizontally welded to the first spring 31. The spring is moved by pressing the handle 35, thereby realizing the tension of the vertical pole. Repeat the above operation and install another one in the connection hole 38 reserved for the vertical pole tension unit 3 at an adjacent position. After installation, by pressing the handle 35, the pole tension unit 3 is installed at the bottom of the scaffold pole and moved upward, and the handle 35 is released to fix it on the pole. The top of the handle 35 facing the inside of the scaffold is welded to the horizontal safety plate 36, a groove 361 is set at the top of the horizontal safety plate 36, and the bottom of the outer side of the groove 361 is welded to the safety fixing ring 37. A ratchet spindle 41 is installed in the middle of the first space of the automatic retracting and releasing unit 4 of the safety rope, and the ratchet 43 is fixed on the ratchet spindle 41. A coil spring 42 is arranged on the ratchet spindle 41. The safety rope 2 is fixed on the ratchet spindle 41 through the device opening and the internal coil spring 42. A double stop shaft 45 is installed at the lower position of the ratchet 43. The safety rope is pulled out of the device opening through the double stop shaft 45. The staff moves along the horizontal rod of the scaffolding to pull out the safety rope 2 for erection. When the staff pulls the safety rope hard, the double stop shaft 45, under the action of the force given by the safety rope and the tension spring 44, the tip of the double stop shaft 45 will hook the ratchet 43 to make the ratchet 43 stuck. At this time, the safety rope will be tightened to play a protective role. A fixing part 46 is welded in the middle of the second space of the automatic retractable safety rope unit 4. A hole is provided at the top of the fixing part 46. A second spring 47 is welded at the bottom of the hole. An elastic pin 49 is set in the hole and welded to the second spring 47. A hole is provided at the outer side of the automatic retractable safety rope unit 4 to allow the elastic pin 49 to extend. A hanging plate 48 is welded at the outer side of the automatic retractable safety rope unit 4. The elastic pin 49 and the hanging plate 48 are used to fix the automatic retractable safety rope unit 4 to prevent the automatic retractable safety rope unit 4 from being subjected to external forces and moving horizontally or vertically. Repeat the above operation to install the second automatic retractable safety rope unit 4. The two automatic retractable safety rope units 4 share a safety rope and are connected through the device port. The two automatic retractable safety rope units 4 are installed in the groove 361 reserved in the horizontal safety plate 36. The elastic pin 49 extends into the reserved hole of the groove 361, and the hanging plate 47 is buckled on the outer side of the groove 361.Two steel bars are welded inside the hole at the top of the lock, and the first steel bar 51 intersects with the hole at the bottom of the lock. The first steel bar 51 is welded with the second steel bar 52 and one side of the top of the lock hole by a third spring 53.
