[0017] Furthermore, it also includes a protective structure, one end of which is mounted on a supporting steel frame, and the other end is used for personal protection; the protective structure includes a fixing component, a moving component, and a clamping component;

[0018] The fixed component includes a rotating column, a rotating shaft, and a connecting column. The rotating column is mounted on a supporting steel frame, and the connecting column is rotatably mounted on the rotating column via the rotating shaft. The moving component is connected to the connecting column.

[0019] Furthermore, the movable component includes a connecting frame, a threaded rod, a turntable, and a movable frame. The connecting frame is a cuboid structure and is mounted on a connecting column. The threaded rod is rotatably mounted inside the connecting frame, and one end of the threaded rod passes through the connecting frame and connects to the turntable.

[0020] The movable frame includes a movable frame, a movable block, a connecting block, and a slider. The movable block is threaded onto a threaded rod. A slide rail is provided on the outer side wall of the connecting frame. The movable frame is fitted onto the outer side of the connecting frame, and the top of the movable frame and the movable block are connected by the connecting block. The left and right inner walls of the movable frame are provided with sliders that are adapted to the slide rails. The movable frame moves along the slide rails via the sliders. The bottom front end of the movable frame is connected to a clamping assembly.

[0021] Furthermore, the clamping assembly includes a connecting rod, a first adjusting block, a second adjusting block, a clamping connecting block, a sliding column, a clamping strap, and a clamping drive assembly. One end of the connecting rod is connected to the movable frame, and the other end of the connecting rod is connected to the first adjusting block.

The top of the adjustment component is connected to the top of the first guardrail and is connected through the second support seat and the second shaft. When the drive component drives the adjustment component to move away from the support steel frame, the adjustment component drives the first guardrail to rotate downward with the first shaft as the rotation point, thereby opening the first guardrail. When it is necessary to close, the drive component can drive the adjustment component to move towards the support steel frame, and at the same time drive the first guardrail to flip upward with the first shaft as the rotation point, thereby completing the closure.

[0027] (3) By setting up rotating columns, rotating shafts and connecting columns, the angles of moving components and clamping components can be adjusted to facilitate construction by operators.

[0028] (4) By rotating the turntable, the turntable drives the threaded rod to rotate, and the threaded rod drives the movable frame that is threaded onto it to move along the direction of the threaded rod. The movable block moves along the direction of the threaded rod, and drives the movable frame and slider to move, and the movable frame drives the clamping assembly connected to it to move.

[0029] (5) The operator can place their waist between the two clamping straps and rotate the rotating rod. The rotating rod drives the lead screw to rotate, and the lead screw drives the second adjusting block to move away from the first adjusting block. The sliding pins at both ends of the second adjusting block move along the adjusting groove, and at the same time drive the two clamping connecting blocks to move closer to each other, thereby driving the clamping straps to move towards the human body and clamping and fixing the human waist. Through the setting of the protective structure, it can play a safety protection role when the first guardrail is open and the operator operates at close range.

[0030] (6) The safety cage described in this invention enables close-range operation during high-altitude operations. At the same time, the protective structure ensures the safety of operators during construction. Attached Figure Description

Detailed Implementation

[0039] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0040] like Figures 1-6 As shown, a safety cage includes

[0041] Platform 10;

[0042] The supporting steel frame 20 is symmetrically installed at the middle position of the front and rear sides of the platform 10;

[0043] The first guardrail 30 is symmetrically located at both ends of the platform 10;

[0044] The second guardrail 40 is symmetrically arranged at both ends of the platform 10 and fixedly installed on the supporting steel frame 20;

[0045] Adjustment structure 50 is used to connect the first guardrail 30 and the platform 10, and the first guardrail 30 can be opened or closed by adjusting the structure.

[0046] In the above technical solution, the first guardrail can be opened or closed by adjusting the structure, which facilitates close-range operation during high-altitude work.

[0047] As a preferred embodiment of the above technical solution, the adjustment structure 50 includes a drive assembly 500, an adjustment assembly 501, a first support base 502, a first shaft 503, a second support base 504, and a second shaft 505. One end of the drive assembly 500 is hinged to the support steel frame 20. The bottom of the adjustment assembly 501 is rotatably connected to the platform 10 through the first support base 502 and the first shaft 503. The first shaft 503 passes through the first support base 502 and connects to the bottom of the first guardrail 30. The top of the adjustment assembly 501 is provided with a second support base 504. The second support base 504 is provided with a second shaft 505, and the second shaft 505 passes through the second support base 504 and connects to the top of the first guardrail 30. The side of the adjustment assembly 501 closest to the support steel frame 20 is hinged to the other end of the drive assembly 500.

[0048] In the above technical solutions, such as Figures 1-4 As shown, the bottom of the adjusting component is connected to the bottom of the first guardrail and is rotatably mounted on the platform via the first support base. The top of the adjusting component is connected to the top of the first guardrail and is connected via the second support base and the second shaft. When the driving component drives the adjusting component to move away from the supporting steel frame, the adjusting component causes the first guardrail to rotate downward around the first shaft, thereby opening the first guardrail. When closing is required, the driving component can drive the adjusting component to move towards the supporting steel frame, while simultaneously causing the first guardrail to flip upward around the first shaft, thereby completing the closing.

[0049] As a preferred embodiment of the above technical solution, the adjustment component 501 is composed of an upper connecting block and a lower connecting block connected together, and the angle between the upper connecting block and the lower connecting block is 90-150°.

[0050] As a preferred embodiment of the above technical solution, the adjustment structure 50 further includes a sliding wheel 506, which is sleeved on the second shaft 505 and located inside the second support seat 504.

[0051] In the above technical solution, by setting up sliding wheels, it can prevent the operator's hand from being injured or pinched when the first guardrail hits the wall or panel when the first guardrail is placed; in addition, when the first guardrail is opened, the sliding wheels can prevent scratches on the wall or panel of the contact channel.

[0052] As a preferred embodiment of the above technical solution, the drive assembly 500 is a cylinder.

[0053] As a preferred embodiment of the above technical solution, it further includes reinforcing blocks 60, which are symmetrically installed on both sides of the supporting steel frame 20 and fixed on the platform 10. Lifting rings 70 are installed on the supporting steel frame 20.

[0054] In the above technical solution, the stability of the supporting steel frame can be improved by setting up reinforcing blocks.

[0055] As a preferred embodiment of the above technical solution, it further includes a protective structure 80, one end of which is mounted on the supporting steel frame 20, and the other end is used for human protection; the protective structure 80 includes a fixing component, a moving component, and a clamping component.

[0056] The fixed component includes a rotating column 801, a rotating shaft, and a connecting column 802. The rotating column 801 is mounted on the supporting steel frame 20, and the connecting column 802 is rotatably mounted on the rotating column 801 via the rotating shaft. The moving component is connected to the connecting column 802.

[0057] In the above technical solutions, such as Figure 4 As shown, the angles of the moving and clamping components can be adjusted by using the rotating column, rotating shaft, and connecting column to facilitate construction by operators.

[0058] As a preferred embodiment of the above technical solution, the movable component includes a connecting frame 803, a threaded rod 804, a turntable 805, and a movable frame. The connecting frame 803 is a cuboid structure and is mounted on a connecting column 802. The threaded rod 804 is rotatably mounted inside the connecting frame 803, and one end of the threaded rod 804 passes through the connecting frame 803 and connects to the turntable 805.

[0059] In the above technical solution, the connecting post 802 can be adopted as follows: Figure 4 The horizontally placed cylinder shown has a connecting frame whose two ends near the connecting column can be connected to the two ends of the connecting column via shafts, facilitating adjustment of its longitudinal angle. Furthermore, a snap-fit ​​structure 90 can be installed at the connection between the connecting column and the connecting frame; after adjusting the longitudinal angle, the connecting frame can be fixed to the connecting column using the snap-fit ​​structure 90. Figure 7 As shown, the snap-fit ​​structure specifically includes a gear 901, a locking block 902, a pull rod 903, and a spring 904. The gear 901 is sleeved on the shaft 905. The connecting end of the connecting frame 803 is a connecting sleeve 906, which is sleeved on the shaft 905. The connecting sleeve 906 has a hole through which the pull rod 903 passes and connects to the locking block 902. The locking block 902 can be engaged between the teeth of the gear 901. The spring 904 is sleeved on the pull rod 903 and located between the locking block 902 and the connecting sleeve 906. When adjustment is needed, by pulling the pull rod upward, rotating the connecting sleeve, and then releasing the pull rod, the locking block is engaged in the gear teeth under the action of the spring.

[0060] By rotating the turntable, the turntable drives the threaded rod to rotate, and the threaded rod drives the movable frame, which is threaded onto it, to move along the direction of the threaded rod.

[0061] The movable frame includes a movable frame 807, a movable block 808, a connecting block 809, and a slider 810. The movable block 808 is threaded onto the threaded rod 804. A slide rail 811 is provided on the outer wall of the connecting frame 803. The movable frame 807 is sleeved on the outer side of the connecting frame 803, and the top of the movable frame 807 is connected to the movable block 808 via the connecting block 809. The left and right inner walls of the movable frame 807 are provided with sliders 810 that are adapted to the slide rail 811. The movable frame 807 moves along the slide rail 811 via the sliders 810. The bottom front end of the movable frame 807 is connected to the clamping assembly.

[0062] In the above technical solution, the moving block moves along the direction of the threaded rod, and drives the moving frame and slider to move, and the moving frame drives the clamping component connected to it to move.

[0063] As a preferred embodiment of the above technical solution, the clamping assembly includes a connecting rod 812, a first adjusting block 813, a second adjusting block 814, a clamping connecting block 815, a sliding column 816, a clamping strap 817, and a clamping drive assembly. One end of the connecting rod 812 is connected to the moving frame 807, and the other end of the connecting rod 812 is connected to the first adjusting block 813. Both ends of the first adjusting block 813 are rotatably connected to the clamping connecting block 815 via shafts. An adjusting groove 818 is provided on the clamping connecting block 815. Both ends of the second adjusting block 814 are disposed in the adjusting groove 818 via the sliding column 816 and can move along the adjusting groove 818. The clamping drive assembly is disposed between the first adjusting block 813 and the second adjusting block 814 and is used to adjust the distance between the second adjusting block 814 and the first adjusting block 813. The clamping connecting block 815 is hinged to the clamping strap 817.

[0064] The clamping drive assembly includes a lead screw 819 and a rotating rod 806. One end of the lead screw 819 is rotatably connected to the first adjusting block 813, and the other end of the lead screw 819 passes through the second adjusting block 814 and is connected to the rotating rod 806. The lead screw 819 and the second adjusting block 814 are threadedly connected.

[0065] In the above technical solution, the operator can place their waist between two clamping straps. By rotating a lever, the lever drives a lead screw to rotate, which in turn moves the second adjusting block away from the first adjusting block. The sliding pins at both ends of the second adjusting block move along the adjusting groove, simultaneously moving the two clamping connecting blocks closer together. This causes the clamping straps to move towards the operator and clamp and fix their waist. The protective structure provides safety protection when the first guardrail is open and the operator is operating at close range.

[0066] As a preferred embodiment of the above technical solution, the two clamping straps 817 together form a circular or elliptical ring, and the inner wall of the clamping straps 817 is provided with rubber or sponge pads.

[0067] The implementation principle of this invention is as follows:

[0068] like Figure 1-6 As shown, the first guardrail can be opened or closed by adjusting the structure, thus facilitating close-range operation during high-altitude work. Specifically:

[0069] The bottom of the adjusting component is connected to the bottom of the first guardrail and is rotatably mounted on the platform via the first support. The top of the adjusting component is connected to the top of the first guardrail and is connected via the second support and the second shaft. When the driving component drives the adjusting component to move away from the supporting steel frame, the adjusting component causes the first guardrail to rotate downward around the first shaft, thereby opening the first guardrail. When closing is required, the driving component can drive the adjusting component to move towards the supporting steel frame, while simultaneously causing the first guardrail to flip upward around the first shaft, thereby completing the closure.

[0070] like Figure 4 As shown, the angles of the moving and clamping components can be adjusted by using the rotating column, rotating shaft, and connecting column, facilitating operator work. Furthermore, the connecting column can be designed as follows: Figure 4 The horizontally placed cylinder shown has a connecting frame with the two ends of the connecting column on the side closest to the connecting column, which can be connected by a shaft to facilitate the adjustment of its longitudinal angle. In addition, a snap-fit ​​structure can be set at the connection between the connecting column and the connecting frame. After the longitudinal angle is adjusted, the connecting frame can be fixed to the connecting column by the snap-fit ​​structure.

[0071] By rotating the turntable, the turntable drives the threaded rod to rotate, which in turn drives the movable frame, which is threaded onto the turntable, to move along the direction of the threaded rod. The movable block moves along the direction of the threaded rod, which in turn drives the movable frame and slider to move, and the movable frame drives the clamping assembly connected to it to move.

[0072] Furthermore, the operator can place their waist between the two clamping straps. By rotating the lever, the lever drives the lead screw to rotate, which in turn moves the second adjusting block away from the first adjusting block. The sliding pins at both ends of the second adjusting block move along the adjusting groove, simultaneously moving the two clamping connecting blocks closer to each other. This causes the clamping straps to move towards the operator and clamp and secure their waist. This protective structure provides safety protection when the first guardrail is open and the operator is operating at close range.

[0073] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
