Description

Technical Field

[0001] The invention relates to the technical field of cable tray installation, in particular to a cable tray hanging installation device. Background Art

[0002] Cable trays are divided into trough type, tray type, ladder type, grid type and other structures, and are composed of brackets, brackets and installation accessories. The cable trays in buildings can be erected independently or laid on various buildings (structures) and pipe gallery brackets. Cables are laid inside the cable trays, and the cable trays can be used to support and protect the cables.

[0003] The Chinese patent with application date: 2022-11-21 and announcement number: CN115864215B discloses a cable tray hanging installation device and installation method under an aerial platform, including a mobile platform, a steel cable is also arranged on the inner side of the mobile platform, a first support mechanism is arranged at one end of the steel cable, and a second support mechanism is arranged at the other end of the steel cable, the first support mechanism and the second support mechanism are used to adjust the straightness, horizontality and height of the steel cable, and the mobile platform and the construction personnel are connected to the steel cable through a safety rope. When the mobile platform falls off or the construction personnel falls during the construction of the cable tray, the steel cable pulls the mobile platform or the construction personnel through the safety rope to ensure the safe construction of the cable tray and reduce the safety risk of construction. When the mobile platform needs to be moved to the next processing area, the construction personnel only need to use the steel cable as a marking line to build the mobile platform, which effectively avoids the deviation of the mobile platform and improves the construction efficiency of the cable tray.

[0004] In this technical solution, the safety of the construction workers is ensured by connecting the steel cable with the safety rope. When the construction workers fall, a large pulling force is suddenly applied to the taut steel cable, and the steel cable will bend downward and deform into a V shape with a large angle. The force applied to the steel cable by the fall of the worker becomes larger at the two inclined parts of the steel cable, which can easily damage the steel cable or even break it. There are safety hazards in ensuring the safety of the construction workers only by a single steel cable. At this time, the first supporting mechanism and the second supporting mechanism are relatively high, with the center of gravity biased upward, and the first supporting mechanism and the second supporting mechanism are easily pulled by the steel cable to shake or even move. Therefore, further improvements can be made. Summary of the invention

[0017] Preferably, the installation method of the cable tray hanging installation device comprises the following specific steps:

[0018] S1. Pre-install the support assembly on the wall of the building through expansion bolts, and then the counterweight platform moves on the ground through the wheels at the bottom, so that the counterweight platform is directly below the middle between the two groups of support assemblies, and then the steel cable is passed around the fixed pulley;

[0019] S2, through the contraction of the output end of the hydraulic cylinder, the counterweight plate is pulled up, so that the wheel is separated from the ground, and the legs are supported on the ground, so that the counterweight platform frame moves down as a whole. In this process, the controller controls the second switch valve to be closed and the first switch valve to be opened. By reducing the distance between the support platform and the counterweight plate, the piston is squeezed to slide into the vertical oil cylinder, and the hydraulic oil in the vertical oil cylinder passes through the connecting pipe into the connecting cylinder and the horizontal oil cylinder. The two groups of piston plates are driven away from each other by hydraulic action, and then the rotating arm is pushed by the piston rod, and the pressure wheel is squeezed on the inclined part of the steel cable to tighten the steel cable;

[0020] S3, then control the switch valve 1 to close through the controller, so that the pressure wheel keeps squeezing the steel cable 1, and then build a high-altitude platform along the horizontal part of the steel cable 1;

[0021] S4, the controller controls the motor to start, driving the connecting shaft and the winding roller to rotate, thereby driving the right half of the steel cable 1 to be gradually wound on the winding roller, and the steel cable 1 wound on the winding roller is gradually released to the left, so that the steel cable 1 slides on the fixed pulley until the safety rope connecting piece moves to the top of the support platform;

[0022] S5. After that, the construction workers on the platform can connect the safety rope to the hanging ring and carry out the cable tray installation work;

[0023] S6. When a construction worker falls or experiences an accident, the pressure on the pressure sensor suddenly changes. The pressure sensor transmits a signal to the controller, which controls the switch valve 1 and the switch valve 2 to open. Under the pressure of the steel cable 1, the arm deflects toward the horizontal oil cylinder, and the piston rod and the piston plate slide toward the inside of the horizontal oil cylinder. The hydraulic oil in the horizontal oil cylinder is discharged through the oil filling supplement, the connecting pipe, the vertical oil cylinder and the drain pipe. The resistance of the hydraulic oil passing through the hollow plate causes the arm to deflect slowly, so that the steel cable 1 slowly switches from a taut state to a loose state. The horizontal part of the steel cable 1 slowly sinks into a V shape, causing the construction worker to slowly move down a certain distance.

[0024] S7, the controller controls the motor to start, the connecting shaft and the winding roller rotate, so that the steel cable 1 slides on the fixed pulley, and the construction workers move along with the steel cable 1. During this process, the construction workers first approach the wall and then gradually move to the ground.

[0025] (III) Beneficial effects

[0026] Compared with the prior art, the present invention provides a cable tray hanging installation device, which has the following beneficial effects:

[0027] 1. The cable tray hanging installation equipment and installation method are connected between two steel cables through a safety rope connector. When the safety rope is connected to the hanging ring, the weight of the construction workers is shared by the two steel cables, making the construction process safer and more reliable.

[0028] 2. The cable tray hanging installation equipment and installation method, when the construction workers fall or other accidents occur, the pressure on the pressure sensor suddenly changes, the pressure sensor transmits the signal to the controller, and the controller controls the switch valve 1 and the switch valve 2 to open. Under the pressure of the steel cable 1, the swing arm deflects toward the horizontal oil cylinder, the piston rod and the piston plate slide toward the inside of the horizontal oil cylinder, and the hydraulic oil in the horizontal oil cylinder is discharged through the oil filling supplement, the connecting pipe, the vertical oil cylinder and the drain pipe, and the resistance of the hydraulic oil passing through the hollow plate causes the swing arm to deflect slowly, so that the steel cable 1 is slowly switched from a taut state to a loose state, so that the construction workers fall smoothly and slowly, avoiding panic among the construction workers;

[0029] 3. The cable tray hanging installation equipment and installation method, and then control the motor to start through the controller, the connecting shaft and the winding roller rotate, so that the steel cable slides on the fixed pulley, and the construction personnel move along with the steel cable. In this process, the construction personnel first approach the wall and then gradually move to the ground, so as to achieve the purpose of facilitating rescue after the construction personnel fall.

[0051] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] See also Figure 1A cable tray hanging and installation device comprises a counterweight platform 100 and two groups of supporting components 400, a winding component 200 is fixedly installed on the top of the counterweight platform 100, and two groups of steel cables 300 are wound on the winding component 200; it also comprises a high-altitude platform 600 fixedly installed on the top wall of the building, and the two groups of supporting components 400 are fixedly installed on the two side walls of the building through expansion bolts; the steel cable 300 passes around the surface of the two groups of supporting components 400, so that the steel cable 300 is in a triangular shape, the steel cable 300 between the two groups of supporting components 400 is horizontal, and the steel cable 300 between the supporting component 400 and the winding component 200 is inclined; a safety rope connector 500 is detachably installed between the two groups of steel cables 300, and a hydraulic buffer component 700 is fixedly installed on the top of the winding component 200, and the hydraulic buffer component 700 is used to apply pressure to the inclined part of the steel cable 300.

[0053] See also Figure 2-Figure 3 The counterweight platform 100 includes a support platform 101, and four groups of legs 102 are fixedly installed at the bottom of the support platform 101. The four groups of legs 102 are distributed in a matrix. The four groups of legs 102 are slidably connected with a counterweight plate 103, and the counterweight is performed through the counterweight plate 103. A hydraulic cylinder 104 is fixedly installed at the center of the bottom of the support platform 101. The signal of the hydraulic cylinder 104 is connected to the controller. The output end of the bottom of the hydraulic cylinder 104 is fixedly installed on the top of the counterweight plate 103. A traveling vehicle 105 is fixedly installed at the bottom of the counterweight plate 103. Wheels 106 are arranged on both sides of the traveling vehicle 105. The controller controls the output shaft of the hydraulic cylinder 104 to extend, driving the counterweight plate 103 to move downward, so that the wheels 106 contact the ground. The output shaft of the hydraulic cylinder 104 continues to extend, which can make the legs 102 leave the ground. At this time, the counterweight platform 100 can move freely on the ground. When the wheels 106 are away from the ground and the legs 102 are supported on the ground, the counterweight platform 100 is prevented from moving on the ground.

[0054] See also Figure 4-Figure 5 The winding assembly 200 includes a storage box 201 fixedly mounted on the top of the counterweight platform 100, a box cover 202 fixedly mounted on the top of the storage box 201, a reducer 203 fixedly mounted on the back of the storage box 201, a motor 204 connected to the back input end of the reducer 203, and the motor 204 is connected to the controller signal.

[0055] A connecting shaft 205 is fixedly installed at the output end of the front side of the reducer 203, and the connecting shaft 205 penetrates and rotates to be connected to the storage box 201. Two sets of winding rollers 206 are fixedly installed on the circumferential surface of the connecting shaft 205, and the two sets of winding rollers 206 are located inside the storage box 201. Two sets of guide tubes 207 are fixedly installed on both sides of the storage box 201. The ends of the guide tubes 207 are horn-shaped, and the steel cable 1 300 passes through the inside of the guide tubes 207 to reduce the friction between the steel cable 1 300 and the ends of the guide tubes 207. The two sets of steel cables 1 300 are respectively wound on the two sets of winding rollers 206 to prevent the steel cables 1 300 from slipping on the winding rollers 206. When the motor 204 and the reducer 203 drive the connecting shaft 205 to rotate, the winding roller 206 winds up the steel cable 300 while releasing the steel cable 300, thereby ensuring that the steel cable 300 is always in a taut state and allowing the steel cable 300 to move.

[0056] See also Figure 6 Each support assembly 400 includes a mounting seat 401, on which two sets of supports 402 are fixedly mounted. The two sets of supports 402 are distributed front and back. A mounting slot 403 is provided through the front side of the supports 402. A pressure sensor 404 is fixedly mounted on the bottom wall of the mounting slot 403. The pressure sensor 404 is connected to the controller signal. A shaft seat 405 is inserted into the mounting slot 403. The shaft seat 405 fits the top wall of the mounting slot 403 and the top of the pressure sensor 404. A rotating shaft 406 is rotatably connected through the center of the shaft seat 405. A fixed pulley 407 is fixedly mounted on one end of the rotating shaft 406. A clamping plate 408 is fixedly mounted on the other end of the rotating shaft 406. The two sets of fixed pulleys 407 are located between the two sets of supports 402. Moreover, the fixed pulley 407 and the clamping plate 408 are clamped on both sides of the support 402, so that the shaft seat 405 is stably set inside the installation groove 403 to prevent the shaft seat 405 from being separated from the installation groove 403. The steel cable 1 300 is attached to the surface of the fixed pulley 407. When the steel cable 1 300 is tightened, it will generate an extrusion force on the fixed pulley 407, so that the shaft seat 405 presses the pressure sensor 404.

[0057] See also Figure 1 and Figure 7The safety rope connector 500 includes a steel cable 2 501, and both ends of the steel cable 2 501 are fixed to the surface of the steel cable 1 300 through a lap joint 502. Two sets of hanging rings 503 are fixedly installed on the surface of the steel cable 2 501. In actual operation, the steel cable 1 300 is composed of a steel cable and a lap joint 502. After the support assembly 400 is installed on the wall, one end of the steel cable 1 300 is passed around the surface of the fixed pulleys 407 of the two sets of support assemblies 400 in turn, and the other end of the steel cable 1 300 is wound on the winding roller 206, and then the two ends of the steel cable 1 300 are connected together through the lap joint 502 to form a ring structure. The length of the steel cable 1 300 that is not wound is controlled by the number of turns of the steel cable 1 300 wound on the winding roller 206 to adapt to different heights and different widths of the building. By rotating the winding roller 206, the steel cable 300 is driven to move to the high-altitude platform 600, and the construction personnel can connect the safety rope to the hanging ring 503. Thus, the safety is protected by the two steel cables 300. When the construction personnel fall, the two steel cables 300 share the pulling force, which is safer.

[0058] Of course, in order to strengthen the connection strength of the ends of the first steel cable 300, the two ends of the first steel cable 300 may overlap a portion, and a plurality of lap joints 502 may be installed at the overlapping portion. Similarly, in order to strengthen the connection strength between the second steel cable 501 and the first steel cable 300, a longer second steel cable 501 may be provided, so that the overlapping portion between the end of the second steel cable 501 and the first steel cable 300 is lengthened, and a plurality of lap joints 502 may be installed at the overlapping portion.

[0059] See also Figure 4 The aerial platform 600 includes four groups of suspension rods 601 fixedly installed on the top wall of the building. The four groups of suspension rods 601 are distributed in a matrix. A support platform 602 is fixedly installed at the bottom end of the four groups of suspension rods 601. A fence rod 603 is fixedly installed between two adjacent groups of support platforms 602. The fence rod 603 is located below the horizontal part of the steel cable 300.

[0060] See also Figure 8The lap joint 502 includes a U-shaped rod 5021 and a clamping plate 5022. Two groups of through holes 5023 are formed on the surface of the clamping plate 5022. The two ends of the U-shaped rod 5021 are inserted into the through holes 5023, so that the U-shaped rod 5021 and the clamping plate 5022 form a ring buckle, and the overlapping part of the steel cable 1 300 and the steel cable 2 501 passes through the inside of the ring buckle. In addition, the clamping plate 5022 is provided with an arc surface facing the steel cable 2 501 to increase the contact area between the clamping plate 5022 and the steel cable 2 501. Threads are provided on the circumferential surfaces of both ends of the U-shaped rod 5021, and nuts 1 5024 are threadedly connected on both ends of the U-shaped rod 5021. The U-shaped rod 5021 and the clamping plate 5022 are clamped on the surface of the steel cable 2 501 and the surface of the steel cable 1 300. Thus, by screwing the nut 1 5024, the clamping plate 5022 is moved on the U-shaped rod 5021, reducing the length inside the annular buckle, so that the U-shaped rod 5021 and the clamping plate 5022 can stably clamp the steel cable 1 300 and the steel cable 2 501.

[0061] See also Fig. 9 Each hanging ring 503 includes a boss 5031 fixedly mounted on the second steel cable 501, a right half ring 5032 is fixedly mounted on the bottom of the boss 5031, a sleeve frame 5033 is sleeved on the outer side of the top of the right half ring 5032, and a left half ring 5034 is fixedly mounted on the bottom of the left end of the sleeve frame 5033. A threaded rod 5035 is fixedly mounted on the right side of the top of the right half ring 5032, a hole is penetrated through the right end of the sleeve frame 5033, and the threaded rod 5035 is inserted into the hole, and a nut 5036 is threadedly connected on the surface of the threaded rod 5035, and the nut 5036 is attached to the right end of the sleeve frame 5033. Therefore, by loosening the nut 5036, the sleeve frame 5033 can move left and right relative to the right half ring 5032, so that the right half ring 5032 is separated from the left half ring 5034.

[0062] The left half ring 5034 has an embedded column 5037 fixedly mounted on the right side of the bottom end, and the right half ring 5032 has an embedded hole 5038 on the left side of the bottom end. The embedded column 5037 and the embedded hole 5038 are adapted to be plugged in. The strength of the bottom connection between the left half ring 5034 and the right half ring 5032 is further enhanced.

[0063] Before the construction personnel enter the aerial platform 600, the winding roller 206 can be rotated to drive the steel cable 1 300 to move, so that the safety rope connector 500 moves close to the ground. The right half ring 5032 can be fitted together with the left half ring 5034 by loosening the nut 2 5036, and then the nut 2 5036 is tightened to stably connect the cable hanger with the hanging ring 503. The winding roller 206 is then rotated to drive the steel cable 1 300 to move; the cable hanger moves with the steel cable 1 300. When the cable hanger moves along the horizontal direction with the steel cable 1 300, the cable hanger will be blocked by the enclosure rod 603, and the cable hanger continues to move with the steel cable 1 300, so that the cable hanger gradually deflects from the vertical state to the horizontal state; until most of the cable hanger is located above the enclosure rod 603, and the hanging ring 503 is still inside the aerial platform 600.

[0064] When the construction workers enter the high-altitude platform 600, the cable hanger can be removed from the hanging ring 503. At this time, the cable hanger is supported by the enclosure rod 603 to keep the cable hanger away from the enclosure rod 603. When installing the cable hanger, the lifting distance of the cable hanger by the construction workers is reduced. Similarly, one end of the cable can be tied to the hanging ring 503 by a cable tie or rope, and the cable can be transported into the high-altitude platform 600 through the above operation process. It plays a role in facilitating the transportation of installation accessories into the high-altitude platform 600.

[0065] See also Figure 10-11 The hydraulic buffer assembly 700 includes a connecting plate 701 fixedly mounted on the top of the winding assembly 200, a transverse oil cylinder 702 fixedly mounted on the top of the connecting plate 701, piston rods 703 are slidably connected to the left and right sides of the transverse oil cylinder 702, a piston plate 704 is fixedly mounted on one end of the piston rod 703 located inside the transverse oil cylinder 702, and two groups of limiting rings 705 are fixedly mounted on the middle of the inner wall of the transverse oil cylinder 702. A connecting cylinder 706 is fixedly mounted on the bottom of the transverse oil cylinder 702, the connecting cylinder 706 is connected to the transverse oil cylinder 702, and the connecting cylinder 706 is located between the two groups of limiting rings 705, and the limiting rings 705 block the piston plates 704, so that the two piston plates 704 are prevented from always being on both sides of the connecting cylinder 706. An oil filling supplement 707 is connected to the bottom of the connecting cylinder 706, and hydraulic oil is transported into the connecting cylinder 706 through the oil filling supplement 707. Under the action of hydraulic pressure, the two groups of piston plates 704 will be driven away from each other.

[0066] Two groups of rotating arms 708 are hinged on the top of the winding component 200, and the two groups of rotating arms 708 are distributed on the left and right. Two groups of piston rods 703 are located on the outside of the horizontal oil cylinder 702 and are hinged at one end in the middle of the rotating arm 708. An arch plate 709 is fixedly installed on the top of the rotating arm 708, and pressure wheels 710 are fixedly installed at both ends of the arch plate 709. The piston plates 704 move away from each other, and the piston rods 703 push the rotating arms 708 to deflect. The pressure wheels 710 fit on the inclined part of the steel cable 300, and as the two piston plates 704 continue to move away from each other, the pressure wheels 710 continue to apply pressure to the inclined part of the steel cable 300, so that the inclined part of the steel cable 300 produces a bend, and in the process, the steel cable 300 is tightened.

[0067] The oil filling and replenishing member 707 includes a connecting pipe 7071 connected to the bottom of the connecting cylinder 706, and the other end of the connecting pipe 7071 is connected to a vertical oil cylinder 7072. A switch valve 1 7073 is provided on the connecting pipe 7071, and a squeeze piston 7074 is slidably connected to the bottom of the vertical oil cylinder 7072. A discharge pipe 7075 is connected to the top circumferential surface of the vertical oil cylinder 7072, and a switch valve 2 7076 is provided on the discharge pipe 7075. The switch valve 1 7073 and the switch valve 2 7076 are connected to the controller signal. The vertical oil cylinder 7072 is fixedly installed at the bottom of the support platform 101, and the squeeze piston 7074 is fixedly installed on the top of the counterweight plate 103. Therefore, when the counterweight plate 103 moves up and separates from the ground, the counterweight platform 100 moves downward as a whole, and the winding assembly 200 moves downward synchronously to tighten the steel cable 1 300. At the same time, as the hydraulic cylinder 104 continues to pull the counterweight plate 103 upward, the distance between the support platform 101 and the counterweight plate 103 is further reduced, and the controller opens the switch valve 1 7073 and closes the switch valve 2 7076. The extrusion piston 7074 presses the hydraulic pressure inside the vertical oil cylinder 7072 into the inside of the horizontal oil cylinder 702, driving the swing arm 708 to deflect, and further tightening the steel cable 1 300. A hollow plate 711 is fixedly installed on the inner wall of the connecting cylinder 706. The controller opens the switch valve 1 7073 and the switch valve 2 7076, and the tightened steel cable 1 300 is squeezed by the pressure wheel 710, driving the swing arm 708 to deflect toward the horizontal oil cylinder 702, and the piston rod 703 and the piston plate 704 slide toward the limit ring 705, squeezing the hydraulic oil, and causing the hydraulic oil to pass through the hollow plate 711, the connecting pipe 7071, the vertical oil cylinder 7072 and the drain pipe 7075.

[0068] The resistance of the hydraulic oil passing through the hollow plate 711 slows down the deflection process of the rotating arm 708, so that the steel cable 300 slowly changes from a taut state to a loose state. This prevents the steel cable 300 from becoming loose quickly, and after the construction worker falls and tightens the steel cable 300 again, it bounces upward due to the reaction force. This prevents the construction worker from falling suddenly and causing panic.

[0069] After rescuing the construction workers, the switch valve 1 7073 can be closed, the switch valve 2 7076 can be opened, and the counterweight plate 103 can be moved downward to squeeze the piston 7074 downward relative to the vertical oil cylinder 7072, so that negative pressure is generated in the vertical oil cylinder 7072, and hydraulic oil can be added to the vertical oil cylinder 7072 through the drain pipe 7075.

[0070] When in use, the installation method of the cable tray hanging installation device has the following specific steps:

[0071] S1. The support assembly 400 is pre-installed on the wall of the building by means of expansion bolts, and then the counterweight platform 100 moves on the ground through the wheels 106 at the bottom, so that the counterweight platform 100 is located directly below the middle between the two sets of support assemblies 400, and then the steel cable 300 is passed around the fixed pulley 407;

[0072] S2, through the contraction of the output end of the hydraulic cylinder 104, the counterweight plate 103 is pulled upward, the wheel 106 is separated from the ground, and the support leg 102 is supported on the ground, so that the counterweight platform 100 moves downward as a whole, and in this process, the switch valve 2 7076 is closed and the switch valve 1 7073 is opened through the controller, and the distance between the support platform 101 and the counterweight plate 103 is reduced, and the piston 7074 is squeezed to slide into the vertical oil cylinder 7072, and the hydraulic oil inside the vertical oil cylinder 7072 passes through the connecting pipe 7071 into the connecting cylinder 706 and the horizontal oil cylinder 702, and the two groups of piston plates 704 are driven away from each other through the hydraulic action, and then the rotating arm 708 is pushed by the piston rod 703, and the pressure wheel 710 is squeezed on the inclined part of the steel cable 1 300 to tighten the steel cable 1 300;

[0073] S3, the controller controls the switch valve 7073 to close, so that the pressure wheel 710 keeps squeezing the steel cable 300, and then the high-altitude platform 600 is built along the horizontal part of the steel cable 300;

[0074] S4, the controller controls the motor 204 to start, driving the connecting shaft 205 and the winding roller 206 to rotate, thereby driving the right half of the steel cable 300 to be gradually wound on the winding roller 206, and the steel cable 300 wound on the winding roller 206 is gradually released to the left, so that the steel cable 300 slides on the fixed pulley 407 until the safety rope connector 500 moves to the top of the support platform 602;

[0075] S5. After that, the construction workers on the support platform 602 can connect the safety rope to the hanging ring 503 to carry out the cable tray installation operation;

[0076] S6. When a construction worker falls or encounters an accident, the pressure on the pressure sensor 404 suddenly changes. The pressure sensor 404 transmits a signal to the controller, which controls the switch valve 1 7073 and the switch valve 2 7076 to open. Under the pressure of the steel cable 1 300, the arm 708 deflects toward the horizontal oil cylinder 702, and the piston rod 703 and the piston plate 704 slide toward the inside of the horizontal oil cylinder 702. The hydraulic oil in the horizontal oil cylinder 702 is discharged through the oil filling supplement 707, the connecting pipe 7071, the vertical oil cylinder 7072 and the drain pipe 7075. The resistance of the hydraulic oil passing through the hollow plate 711 causes the arm 708 to deflect slowly, so that the steel cable 1 300 is slowly switched from a taut state to a loose state. The horizontal part of the steel cable 1 300 slowly concave into a V shape, causing the construction worker to slowly move down a certain distance.

[0077] S7. The controller controls the motor 204 to start, and the connecting shaft 205 and the winding roller 206 rotate, so that the steel cable 300 slides on the fixed pulley 407, and the construction workers move along with the steel cable 300. During this process, the construction workers first approach the wall and then gradually move to the ground.

9. The installation method of the cable tray hanging installation equipment according to claim 8, characterized in that: The specific steps are as follows: S1. The support assembly (400) is pre-installed on the wall of the building by means of expansion bolts, and then the counterweight platform (100) moves on the ground via the wheels (106) at the bottom, so that the counterweight platform (100) is located directly below the middle between the two groups of support assemblies (400), and then the steel cable 1 (300) is passed around the fixed pulley (407); S2, the output end of the hydraulic cylinder (104) contracts, the counterweight plate (103) is pulled upward, the wheel (106) is separated from the ground, the legs (102) are supported on the ground, and the counterweight platform (100) is moved downward as a whole. In this process, the controller controls the second switch valve (7076) to close and the first switch valve (7073) to open, and the distance between the support platform (101) and the counterweight plate (103) is reduced, so that the extrusion piston (7074) slides into the vertical oil cylinder (7072), and the hydraulic oil in the vertical oil cylinder (7072) passes through the connecting pipe (7071) and enters the connecting cylinder (706) and the transverse oil cylinder (702). The two sets of piston plates (704) are driven away from each other through the hydraulic action, and then the rotating arm (708) is pushed by the piston rod (703), and the pressure wheel (710) is pressed on the inclined part of the steel cable (300), so that the steel cable (300) is tightened; S3, the controller is then used to control the switch valve 1 (7073) to close, so that the pressure wheel (710) remains in a state of squeezing the steel cable 1 (300), and then a high-altitude platform (600) is built along the horizontal portion of the steel cable 1 (300); S4, the controller controls the motor (204) to start, driving the connecting shaft (205) and the winding roller (206) to rotate, thereby driving the right half of the steel cable (300) to be gradually wound on the winding roller (206), and the steel cable (300) wound on the winding roller (206) is gradually released to the left, so that the steel cable (300) slides on the fixed pulley (407) until the safety rope connecting member (500) moves to the top of the support platform (602); S5. Afterwards, the construction workers on the support platform (602) can connect the safety rope to the hanging ring (503) and carry out the cable tray installation operation; S6. When a construction worker falls or experiences an accident, the pressure on the pressure sensor (404) suddenly changes. The pressure sensor (404) transmits a signal to the controller, which controls the switch valve 1 (7073) and the switch valve 2 (7076) to open. Under the pressure of the steel cable 1 (300), the rotating arm (708) deflects toward the horizontal oil cylinder (702), and the piston rod (703) and the piston plate (704) slide toward the inside of the horizontal oil cylinder (702). The hydraulic oil in the horizontal oil cylinder (702) is discharged through the oil filling supplement (707), the connecting pipe (7071), the vertical oil cylinder (7072) and the drain pipe (7075). The resistance of the hydraulic oil when passing through the hollow plate (711) causes the rotating arm (708) to slowly deflect, thereby slowly switching the steel cable 1 (300) from a taut state to a loose state. The horizontal part of the steel cable 1 (300) slowly sinks into a V shape, causing the construction worker to slowly move down a certain distance. S7, the controller controls the motor (204) to start, the connecting shaft (205) and the winding roller (206) to rotate, so that the steel cable (300) slides on the fixed pulley (407), and the construction workers move along with the steel cable (300). During this process, the construction workers first approach the wall and then gradually move to the ground.
