[0001] This invention relates to the field of anti-fall hangers for color steel roof tiles, specifically an anti-fall hanging point fixture for color steel roof tiles. Background Technology

[0002] The prior art, disclosed in CN207597911U, pertains to the field of safety protection tools for high-altitude operations, and particularly relates to a fall arrest device and a roof system. The fall arrest device includes a fixed base and a first cable; the fixed base includes a first frame and a first fixing clamp, which are detachably connected; multiple fixed bases are spaced apart, and a second cable connects the first frames of adjacent fixed bases; one end of the first cable along its length is connected to the second cable and is movable along the length of the second cable, while the other end is used to connect to the worker. The roof system includes the aforementioned fall arrest device and a roof. The purpose of this device and roof system is to provide a fall arrest device and roof system to solve the technical problem in the prior art where the fixed base cannot adapt to roofs of different shapes.

[0003] However, the device still has some obvious defects in use: the various fixing clips of the device need to be fixed one by one, and the installation and disassembly process is time-consuming and laborious. In addition, the device is connected to the corrugated steel tile by a clamping method, and its main body cannot slide on the corrugated steel tile, which is not conducive to later adjustment. Summary of the Invention

[0004] The purpose of this invention is to provide a fall-prevention hanging point fixture for color steel tile roofs to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A fall arrestor fixture for a color steel tile roof includes a connecting frame with telescopic sleeves fixedly installed at its four corners. A telescopic hanger is movably inserted into the telescopic sleeve. The telescopic hanger extends outward from the telescopic sleeve without external force, connected to an elastic mechanism. An embedding groove is also provided at the axis of the connecting frame. A fastening turntable is movably installed in the embedding groove via a bearing. The fastening turntable is connected to the telescopic hanger one-to-one via a winding fastening rope. During the rotation of the fastening turntable, the fastening rope winds up, thereby causing the telescopic hanger to retract into the telescopic sleeve against the work done by the elastic mechanism. Each telescopic bracket has a clamping wheel fixed at the end away from the telescopic sleeve via a rotating shaft. The clamping wheel is movably engaged with a clamping block that is slidably moved. The clamping wheel and the clamping block clamp the corrugated steel sheet. The clamping block is connected to the telescopic piston via a telescopic connecting rod. The telescopic piston is movably installed in a driven telescopic cylinder. The driven telescopic cylinder is connected to an active piston cylinder in the fastening turntable via an oil passage opened in the telescopic bracket, connecting frame, and fastening turntable. The active piston cylinder is connected to a lifting piston rod. The lifting and lowering of the lifting piston rod synchronously drives the telescopic movement of the clamping block. A spinning rod is also mounted on the fastening turntable via a mounting bracket. The spinning rod moves downward by abutting against the lifting piston rod. The fastening turntable is also equipped with a locking mechanism to restrict the return of the spinning rod. The locking mechanism keeps the spinning rod pressed against the lifting piston rod. One side of the connecting frame is also equipped with an anti-rotation mechanism to limit the reverse rotation of the fastening turntable.

[0006] Preferably, the elastic mechanism that pushes the telescopic bracket to extend outward without external force includes a fixed seat, a movable seat, and a compression spring. The fixed seat is fixedly installed inside the telescopic sleeve, the movable seat is fixedly connected to one end of the telescopic bracket inserted into the telescopic sleeve, and the two ends of the compression spring are respectively connected to the fixed seat and the movable seat.

[0007] Preferably, the locking mechanism for preventing the spinning rod from disengaging from the lifting piston rod includes a limiting seat, a limiting rod, and a limiting spring arranged symmetrically at the top and bottom. The limiting seat has a through hole for the limiting rod to pass through. The two ends of the limiting spring are respectively connected to the limiting seat and the limiting rod. The spinning rod has a corresponding limiting hole for the limiting rod to be inserted. When the limiting rod enters the limiting hole, the spinning rod remains in contact with the lifting piston rod.

[0008] Preferably, the anti-rotation mechanism for limiting the reverse rotation of the fastening turntable includes several anti-slip claws, abutment springs, and abutment seats. The anti-slip claws are movably mounted on the connecting frame via a rotating shaft. The outer edge of the fastening turntable protruding from the embedded groove is provided with an anti-rotation tooth groove that cooperates with the anti-slip claws. The abutment springs push the anti-slip claws to cooperate with the anti-rotation tooth grooves, thereby preventing the fastening turntable from rotating.

[0009] Preferably, the clamping block and the clamping wheel are provided with anti-slip grooves on the side they abut against each other during the clamping process, and the rotation of the clamping wheel is restricted by the cooperation of the anti-slip grooves.

[0010] Preferably, a return spring is also sleeved on the outer side of the lifting piston rod to push it upward without external force.

[0011] Preferably, the fastening rope consists of an outer steel strand braided tube and an inner oil delivery pipe, wherein the oil delivery pipe connects the active piston cylinder to an oil delivery channel opened on one side of the telescopic bracket.

[0012] Preferably, a pair of wire rope fixing blocks are also installed on the connecting frame.

[0013] Compared with the prior art, the beneficial effects of the present invention are: The four corners of this invention that contact the corrugated steel tile edges use four clamping wheels. Before clamping, the parts can be slidably adjusted on the corrugated steel tile edges. When it is necessary to tighten them, simply press the screw rod to lock all four clamping wheels at the same time. This fixing method is efficient and convenient, greatly reducing the difficulty of disassembly and assembly and improving work efficiency. Attached Figure Description

Detailed Implementation

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figure 1-7 The present invention provides a technical solution: Example 1: A fall-prevention hanging point fixture for a color steel tile roof includes a connecting frame 1. Telescopic sleeves 2 are fixedly installed at the four corners of the connecting frame 1. Telescopic hangers 3 are movably inserted into the telescopic sleeves 2. The telescopic hangers 3 are connected to the elastic mechanism and extend outwards from the telescopic sleeves 2 without external force. An embedding groove 4 is also provided at the axis of the connecting frame 1. A fastening turntable 6 is movably installed in the embedding groove 4 through a bearing 5. The fastening turntable 6 is connected to the telescopic hangers 3 one-to-one through a fastening rope 7 that is wound and coiled. During the rotation of the fastening turntable 6, the fastening rope 7 is wound up, thereby driving the telescopic hangers 3 to retract into the telescopic sleeves 2 by overcoming the elastic mechanism. The telescopic bracket 3 is equipped with a clamping wheel 8 at the end away from the telescopic sleeve 2 via a rotating shaft. The clamping wheel 8 is in movable cooperation with the clamping block 9 which is slidably moved. The clamping wheel 8 and the clamping block 9 clamp the color steel corrugated sheet 10. The clamping block 9 is connected to the telescopic piston 12 via the telescopic connecting rod 11. The telescopic piston 12 is movably installed in the driven telescopic cylinder 13. The driven telescopic cylinder 13 is connected to the active piston cylinder 15 in the fastening turntable 6 via the oil passage 14 opened in the telescopic bracket 3, the connecting frame 1, and the fastening turntable 6. The active piston cylinder 15 is connected to the lifting piston rod 16. The lifting piston rod 16 drives the extension and retraction of the clamping block 9 synchronously. A spinneret 18 is also mounted on the fastening turntable 6 via a mounting bracket 17. The spinneret 18 pushes the lifting piston rod 16 downward by abutting against it. The fastening turntable 6 is also provided with a locking mechanism to limit the reset of the spinneret 18. The locking mechanism keeps the spinneret 18 pressed against the lifting piston rod 16. One side of the connecting frame 1 is also equipped with an anti-rotation mechanism to limit the reverse rotation of the fastening turntable 6.

[0018] In this embodiment, the connecting frame 1 serves as the main load-bearing structure for various components. Telescopic sleeves 2 are installed at its four corners, and telescopic hangers 3 are telescopically mounted inside the telescopic sleeves 2. The rotation of the fastening turntable 6 drives the fastening rope 7 to retract, thereby causing the telescopic hangers 3 to telescopically extend and retract. When the fall arrestor fixture needs to be installed on the corrugated steel ribs 10, rotating the fastening turntable 6 causes the telescopic hangers 3 to extend and retract from their maximum extended state into the telescopic sleeves 2. Since a clamping wheel 8 is provided at the end of the telescopic hanger 3 away from the telescopic sleeve 2, the four clamping wheels 8 tighten the adjacent pair of corrugated steel ribs 10, thus allowing the fall arrestor fixture to be installed movably. In this state, the fall arrestor fixture can slide horizontally on the corrugated steel ribs 10 via the four clamping wheels 8, thereby adjusting the fixed position of the fall arrestor fixture. When it is necessary to fix it... At a set time, the lifting piston rod 16 is pressed by the swivel rod 18. The lifting piston rod 16 descends and pushes the hydraulic oil filled in the active piston cylinder 15 through the oil channel 14 into the driven telescopic cylinder 13, thereby pushing the telescopic piston 12 to move. The movement of the telescopic piston 12 drives the telescopic connecting rod 11 and the clamping block 9 to move. Thus, the color steel corrugated 10 is fixedly clamped by the bidirectional clamping of the clamping block 9 and the clamping wheel 8. During the clamping process, the clamping block 9 abuts against the clamping wheel 8. Anti-slip grooves 29 are opened on the side of the clamping block 9 and the clamping wheel 8 that abut against each other. The anti-slip grooves 29 restrict the rotation of the clamping wheel 8, further ensuring the fixation of the anti-fall hanging point fixture. The swivel rod 18 is kept pressed against the lifting piston rod 16 under the drive of the locking mechanism, and the fastening turntable 6 is kept traction on the telescopic hanging frame 3 under the action of the anti-rotation mechanism.

[0019] Example 2: The elastic mechanism that pushes the telescopic bracket 3 to extend outward without external force includes a fixed seat 19, a movable seat 20, and a compression spring 21. The fixed seat 19 is fixedly installed inside the telescopic sleeve 2. The movable seat 20 is fixedly connected to one end of the telescopic bracket 3 inserted into the telescopic sleeve 2. The two ends of the compression spring 21 are connected to the fixed seat 19 and the movable seat 20, respectively.

[0020] In this embodiment, the specific structure of the elastic mechanism is further disclosed, in which the movable seat 20 is pushed outward by the thrust of the compression spring 21.

[0021] Example 3: The locking mechanism used to prevent the spinning rod 18 from disengaging from the lifting piston rod 16 includes a limiting seat 22, a limiting rod 23, and a limiting spring 24 arranged symmetrically at the top and bottom. The limiting seat 22 has a through hole for the limiting rod 23 to pass through. The two ends of the limiting spring 24 are respectively connected to the limiting seat 22 and the limiting rod 23. The spinning rod 18 has a corresponding limiting hole 25 for the limiting rod 23 to be inserted. When the limiting rod 23 enters the limiting hole 25, the spinning rod 18 remains in contact with the lifting piston rod 16.

[0022] In this embodiment, the specific structure of the locking mechanism is further disclosed. When the spinning rod 18 is pressed down against the lifting piston rod 16, the limiting rod 23 is inserted into the limiting hole 25 to restrict the movement of the spinning rod 18. When it is necessary to release the restriction, it is only necessary to pull the limiting rod 23 to disengage it from the limiting hole 25.

[0023] Example 4: The anti-rotation mechanism for limiting the reverse rotation of the fastening turntable 6 includes several anti-slip claws 26, abutment springs 27, and abutment seats 28. The anti-slip claws 26 are movably mounted on the connecting frame 1 via a rotating shaft. The outer edge of the fastening turntable 6 protruding into the embedded groove 4 is provided with anti-rotation tooth grooves that cooperate with the anti-slip claws 26. The abutment springs 27 push the anti-slip claws 26 to cooperate with the anti-rotation tooth grooves, thereby preventing the fastening turntable 6 from rotating.

[0024] In this embodiment, the specific structure of the anti-rotation mechanism is further disclosed. The anti-rotation tooth groove is opened on the outer edge of the fastening turntable 6 protruding into the groove 4 by the anti-rotation claw 26, thereby restricting its rotation. When it is necessary to release the rotation restriction, the anti-rotation claw 26 can be moved to disengage from the anti-rotation tooth groove.

[0025] Example 5: In this embodiment, a return spring 30 is also sleeved on the outside of the lifting piston rod 16 to push it upward without external force. The setting of the return spring 30 makes the lifting piston rod 16 maintain an outward extension state without external force.

[0026] Example 6: The fastening rope 7 consists of an outer steel strand braided tube 31 and an inner oil supply pipe 32. The oil supply pipe 32 connects the active piston cylinder 15 to the oil supply channel 14 opened on one side of the telescopic bracket 3.

[0027] In this embodiment, the structure is further simplified. The fastening rope 7 serves not only as the traction mechanism of the telescopic bracket 3, but also as the communication mechanism between the driven telescopic cylinder 13 and the active piston cylinder 15.

[0028] Example 7: In this embodiment, a pair of wire rope fixing blocks 33 are also installed on the connecting frame 1. The anti-fall wire is installed through the wire rope fixing blocks 33, so that maintenance personnel can connect the anti-fall safety rope to the anti-fall wire through the hook when working on the roof, thereby ensuring their safety.

[0029] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
