Description

Technical Field

[0001] The present invention relates to the technical field of defect elimination frames, in particular to a subway defect elimination frame with a protective net. Background Art

[0002] As an important means of transportation in the city, the subway is bound to have various equipment defects during operation, requiring staff to carry out defect elimination operations in a timely manner. During subway defect elimination operations, staff often need to use work frames to reach specific locations for operations. Due to the complex working environment and certain risks of high-altitude operations, it is necessary to install protective nets on the frames to ensure the personal safety of staff.

[0003] However, the existing common methods of fixing protective nets, such as tying or simple hooks, are prone to loosening or even falling off when subjected to external force or accidentally touched by workers, and cannot provide reliable safety protection for workers. In actual operations, sometimes only part of the frame needs to be protected, and sometimes the entire frame needs to be protected. However, the current installation methods of protective nets are mostly relatively fixed, and it is difficult to quickly and flexibly adjust the installation position and range of the protective net according to actual needs, which reduces work efficiency.

[0004] In view of the above problems, the present invention proposes a subway defect elimination frame with a protective net, which aims to achieve stable hanging of the protective net and meet the needs of flexible adjustment of the installation position. Summary of the Invention

[0005] To achieve the above-mentioned purpose, the present invention proposes a subway defect elimination frame with a protective net, comprising a frame body and a protective net. The frame body is composed of vertical rods, horizontal rods and foot pedals. The surface of the vertical rods is installed with mounting arc plates, which are fixed to the surface of the vertical rods by fixing mechanisms. The surface of the mounting arc plates is fixedly connected with hooks. The hooks are divided into upper hooks and lower hooks. The opening of the upper hook is upward and the opening of the lower hook is downward. The rope of the protective net is located inside the upper hook and the lower hook.

[0006] In one example, the fixing mechanism includes a sliding block fixedly mounted on the inner annular surface of the mounting arc plate, a groove is formed on the surface of the vertical rod, and the surface of the sliding block overlaps the inner wall of the groove.

[0007] In one example, a mounting hole is provided on the surface of the mounting arc plate, a screw is installed inside the mounting hole, and a plurality of threaded holes adapted to the screw are provided on the surface of the vertical rod, and the surface of the screw is threadedly connected to the inner wall of the threaded hole.

[0008] In one example, T-shaped grooves are provided on both sides of the sliding block, the inner wall of the T-shaped groove is slidably connected to a moving block, the opposite surface of the moving block and the T-shaped groove is fixedly connected to a return spring, and the side of the moving block away from the return spring is fixedly connected to a positioning block.

[0009] In one example, the inner side wall of the groove is provided with a plurality of positioning grooves adapted to the positioning block, and the positions of the positioning grooves correspond laterally to the positions of the threaded holes, and the front and back sides of the positioning block are both arc-shaped.

[0010] In one example, a brake caster is fixedly connected to the bottom end of the vertical rod.

[0011] In one example, an oblique support cylinder is rotatably mounted on the surface of the crossbar, an adjusting rod is threadedly connected to the inner wall of the oblique support cylinder, a friction pad is rotatably mounted on the bottom end of the adjusting rod through a ball joint, and an adjusting block is fixedly connected to the surface of the adjusting rod.

[0012] In one example, the protective net is wrapped around the surface of the frame through hooks.

[0013] In one example, the hook is disposed on an outer surface of the frame and away from an interior of the frame.

[0014] The subway fault elimination frame with a protective net proposed by the present invention can bring the following beneficial effects: 1. The present invention installs a protective net on the surface of the frame, and the protective net is hung by a uniquely designed hook. The hook is divided into an upper hook and a lower hook. During installation, the rope on the protective net is tilted and placed on the openings of the upper hook and the lower hook respectively, and then placed inside. Such a structure blocks the rope when it moves up and down without tilting, effectively preventing the protective net from falling off, providing reliable and safe protection for the staff, reducing the risk of falling during high-altitude operations, and ensuring the safety of personnel. At the same time, the protective net can be flexibly hung at different heights and positions to meet diverse protection needs, and can better adapt to the complex environment and different working height requirements in subway fault elimination work, ensuring that the staff are within the safety protection range when working at various positions of the frame.

[0015] 2. The present invention is connected to the hook by setting an installation arc plate, and the position of the hook can be flexibly adjusted by sliding the sliding block in the groove of the vertical rod. The mounting hole of the installation arc plate and the threaded hole of the vertical rod cooperate with the screw to fix the installation arc plate in a suitable position, and the T-slots, moving blocks, return springs and positioning blocks on both sides of the sliding block interact with the positioning grooves, so that the sliding block can slide stably and automatically position in the groove of the vertical rod. This not only makes it convenient for workers to quickly adjust the position of the protective net according to work requirements and improves work efficiency, but also does not require complex tools and tedious processes.

[0024] like Figures 1 to 8 As shown, the present invention proposes a subway fault-eliminating frame with a guard net, including a frame body 1, a ladder installed inside the frame body 1, and the ladder can be used to climb to the top of the frame body 1. The frame body 1 is composed of a vertical rod 101, a horizontal rod 102 and a foot pedal 103. An entrance is provided on the upper surface of the foot pedal 103, and the position of the entrance corresponds to the top of the ladder. A shielding plate is installed on the inner wall of the entrance by rotating a hinge. The shielding plate can be rotated. When climbing to the foot pedal 103 through the ladder, the shielding plate can be pushed open to facilitate the staff to pass through the entrance. After passing, the shielding plate can be covered to block the entrance to prevent the foot pedal 103 from stepping on empty space. The vertical rod 101 and the horizontal rod 102 are fixed by connecting pieces. The number of vertical rods 101 and horizontal rods 102 can be increased or decreased by disassembling and assembling the connecting pieces, thereby adjusting the height of the entire frame. There are many types of connecting pieces, and the attached Figure 8The present invention provides a kind of commonly used connecting buckle for demonstration, and the connecting buckle is sleeved on the surface of vertical rod 101, and the connecting buckle is installed with mounting bolts, and the mounting bolts are clamped in the countersunk holes provided on the vertical rod 101. In order to facilitate the height adjustment of the frame body 1, the vertical rod 101 is divided into a plurality of branch rods for connection, and the bottom end of the branch rod is installed with a threaded column, and the top end of the branch rod is provided with a threaded mounting groove adapted to the threaded column. By screwing the threaded column into the threaded mounting groove, the height adjustment of the vertical rod 101 can be achieved, thereby adjusting the height of the entire frame body 1. The footrest 103 is installed on the top of the frame body 1, and both sides of the footrest 103 are fixedly connected with a clamping ring, which is sleeved on the surface of the cross bar 102, making it convenient for the staff to work above the frame body 1. A protective net 5 is installed on the surface of the frame body 1, and a groove is provided on the surface of the vertical rod 101. The inner wall of the groove is slidably connected to a sliding block 2, and the surface of the sliding block 2 is fixedly connected to the mounting arc plate 3, and the inner ring surface of the mounting arc plate 3 overlaps the surface of the vertical rod 101.

[0025] The hook 4 is fixed on the surface of the arc plate 3, and the protective net 5 is hung by the hook 4 to facilitate the installation of the protective net 5 on the frame 1. In order to ensure the stability of the protective net 5 on the hook 4, as shown in FIG. Figure 3 As shown, the hook 4 is divided into an upper hook 401 and a lower hook 402. The opening of the upper hook 401 is upward, and the opening of the lower hook 402 is downward. When the protective net 5 is installed, as shown in FIG. Figure 6 As shown, the rope on the protective net 5 is tilted and located at the openings of the upper hook 401 and the lower hook 402 respectively, and the rope is placed inside the upper hook 401 and the lower hook 402 through the openings of the upper hook 401 and the lower hook 402. With this design, when the rope on the protective net 5 is not tilted, it will be blocked when moving up and down. When the rope moves upward to the opening of the upper hook 401, the rope will be blocked by the lower hook 402. Similarly, when the rope moves downward to the opening of the lower hook 402, it will be blocked by the upper hook 401, thereby ensuring that the rope of the protective net 5 is located inside the hook 4, ensuring the stability of the hook 4 hanging the protective net 5.

[0026] Because in actual work use, sometimes only part of the frame 1 needs to be protected by the protective net 5, and sometimes the entire frame 1 needs to be protected by the protective net 5, so we need to flexibly adjust the position of the hook 4. Since the hook 4 is fixed on the surface of the mounting arc plate 3, the position of the mounting arc plate 3 can be adjusted by moving the position of the mounting arc plate 3. After adjusting the position of the mounting arc plate 3, we need to fix the position of the mounting arc plate 3, open a mounting hole on the surface of the mounting arc plate 3, and open a number of threaded holes on the surface of the vertical rod 101, install a screw 6 inside the mounting hole, and screw the screw 6 into the threaded hole and press the mounting arc plate 3 with the screw 6 to complete the position fixation of the mounting arc plate 3.

[0027] In order to ensure that the screw 6 can be smoothly inserted into the threaded hole, T-slots are provided on both sides of the sliding block 2, and the inner wall of the T-slot is slidably connected with a moving block 7, and the moving block 7 is fixedly connected to the opposite surface of the T-slot with a return spring 8, and the side of the moving block 7 away from the return spring 8 is fixedly connected with a positioning block 9, and a number of positioning grooves adapted to the positioning block 9 are provided on the inner side wall of the groove, and the position of the positioning groove corresponds laterally to the position of the threaded hole. When the positioning block 9 is inserted into the positioning groove, since the position of the positioning groove corresponds to the position of the threaded hole, it can be ensured that the position of the mounting hole on the mounting arc plate 3 corresponds to the position of the threaded hole, which facilitates the installation of the screw 6.

[0028] The front and back sides of the positioning block 9 are both arc-shaped. When the sliding block 2 is inserted into the groove, the arc surface of the positioning block 9 is forced to be retracted. At this time, the positioning block 9 pushes the moving block 7 to squeeze the return spring 8. The return spring 8 is squeezed, and then the sliding block 2 is moved up and down to drive the positioning block 9 to move. When the positioning block 9 moves to the position of the positioning groove, the elastic force of the return spring 8 will push the positioning block 9 to insert into the positioning groove. At this time, the positioning of the sliding block 2 can be completed. Similarly, when the sliding block 2 is pulled out of the groove, the arc surface of the positioning block 9 is forced to be retracted, and the sliding block 2 can be pulled out, thereby facilitating the increase or decrease of the hook 4 or the replacement of the position.

[0029] In order to facilitate the movement of the frame 1, a brake caster 10 is fixedly connected to the bottom end of the vertical rod 101, and an oblique support cylinder 11 is rotatably installed on the surface of the horizontal rod 102. The inner wall of the oblique support cylinder 11 is threadedly connected to an adjusting rod 12, and a friction pad 13 is rotatably installed on the bottom end of the adjusting rod 12 through a ball joint, and an adjusting block is fixedly connected to the surface of the adjusting rod 12 to facilitate the rotation of the adjusting rod 12. After moving the frame 1 to a suitable position, the oblique support cylinder 11 is rotated so that the friction pad 13 overlaps the ground. At this time, the rotating adjustment block drives the adjusting rod 12 to move, and the adjusting rod 12 pushes the friction pad 13 to rub against the ground to increase resistance, so that the oblique support cylinder 11 obliquely supports the frame 1, ensuring that the position of the frame 1 is stable.
