Description

Technical Field

[0001] The present application relates to the technical field of fully enclosed sound barrier construction, and in particular to a crane for the construction of fully enclosed sound barriers for rail transit. Background Art

[0002] In rail transit projects, fully enclosed sound barriers are often installed along the tracks to reduce noise disturbance to residents on both sides of the road. These barriers primarily consist of two components: steel columns and sound-absorbing panels. The columns are fixed to the road's crash barriers or pre-buried steel plates along the track, while the panels are secured within the column slots.

[0003] During the construction of a fully enclosed sound barrier, workers typically install or adjust the transparent PC panels at the top of the barrier by scaffolding or ladders placed underneath the inner side of the barrier. They then move the scaffolding or ladders to install or adjust the panels elsewhere. However, the presence of tracks underneath the inner side of the barrier hinders the movement and adjustment of the scaffolding or ladders, which takes a long time and reduces construction efficiency. Summary of the Invention

The mounting rail is used to be detachably arranged on the top end of the inner side of the sound barrier. The length direction of the mounting rail is arranged in the horizontal direction. The sliding direction of the boom is parallel to the length direction of the mounting rail. A hanging basket is arranged on the boom, and the hanging basket is used to load workers. The mounting rail is provided with a driving member for driving the boom to slide.

[0007] By adopting the above technical solution, workers stand in the hanging basket and drive the boom through the driving part to drive the hanging basket to move horizontally inside the sound barrier, which is convenient for workers to install or adjust the transparent PC panels at different positions of the sound barrier, saving workers' time in climbing and moving ladders or scaffolding, and helping to improve work efficiency.

[0009] By adopting the above technical solution, the lifting member drives the hanging basket to slide in the direction away from the mounting rail, so that the hanging basket moves to the ground, making it easier for workers to enter the hanging basket. Workers do not need to climb the scaffolding to enter the hanging basket at a certain height, which can save a certain amount of time, help improve work efficiency, and improve safety at the same time.

[0010] Preferably, the driving member includes a connecting rope and a first winch arranged on the mounting rail, the connecting rope is relatively arranged on both sides of the boom along the length direction of the mounting rail, the ends of the connecting ropes on both sides away from the boom are wound around the first winch and are wound in opposite directions, the first winch is located at one end in the length direction of the mounting rail, a guide pulley is provided on the side of the mounting rail away from the first winch, and the connecting rope on the side away from the first winch is slidably overlapped on the guide pulley.

[0011] By adopting the above technical solution, the first winch is started, and the first winch is rotated forward or reversed to achieve the goal of reeling in the connecting rope on one side while unreeling the connecting rope on the other side. This enables the connecting rope to pull the boom and drive the hanging basket to slide on the mounting rail, making it convenient for workers to install or adjust the transparent PC panels at different positions of the sound barrier, saving workers' time in climbing and moving ladders or scaffolding, and helping to improve work efficiency.

[0014] Preferably, the length direction of the mounting rail is parallel to the length direction of the sound barrier.

[0015] By adopting the above technical solution, the boom drives the hanging basket to slide along the length direction of the sound barrier, with a large movable range. The transparent PC panels can be adjusted or installed in more positions on the sound barrier, thereby further saving time and helping to improve work efficiency.

[0017] By adopting the above technical solution, when a worker falls from a side panel, he will first press the first extrusion bar on the corresponding side panel to make the first extrusion bar slide toward the direction close to the corresponding side panel. At this time, the second adsorption part on the corresponding side is separated from the first adsorption part through the transmission part, and the protective frame rotates in the direction away from the corresponding side panel under the action of its own gravity, so that the lifting rope is tensioned and the protective frame is unfolded, which helps to catch the falling worker and improves the safety performance to a certain extent.

[0018] Preferably, the first adsorption component includes an iron sheet arranged on the protective frame, and the second adsorption component includes a magnet arranged on the side panel, and the magnet is used to be adsorbed and cooperated with the iron sheet on the corresponding side, and the adsorption force between the magnet and the corresponding iron sheet is greater than the gravity of the protective frame.

[0019] By adopting the above technical solution, the protective frame can be kept close to the corresponding side panels through the adsorption cooperation between the magnets and the corresponding iron sheets, so that the protective frame can be folded and stored, providing convenience for workers to enter and exit the hanging basket, while taking up little space and being easy to transport.

[0020] Preferably, the transmission member includes an abutment rod arranged at one end of the first extrusion strip close to the side plate, the abutment rod is slidably passed through the corresponding side plate, and the end of the abutment rod away from the first extrusion strip is used to abut against the protective frame on the corresponding side.

[0021] By adopting the above-mentioned technical solution, when the first extrusion strip slides toward the direction close to the corresponding side panel, it drives the abutment rod to slide toward the direction close to the protective frame, so that the abutment rod pushes the protective frame on the corresponding side to rotate toward the direction away from the side panel, thereby separating the magnet on the side panel and the corresponding patch, which can facilitate the rotation of the protective frame.

[0023] By adopting the above technical solution, when a worker falls from a side panel, he will first press the first extrusion strip on the corresponding side panel, so that the first extrusion strip drives the abutment rod to slide toward the direction close to the protective frame, and the abutment rod pushes the protective frame to separate the magnet and the corresponding iron sheet, and at the same time, the rack drives the corresponding gear to rotate, and the reel unwinds the transmission rope. At this time, the protective frame rotates downward under the action of gravity, and then the falling worker presses the second extrusion strip on the corresponding side panel, driving the second extrusion strip to slide toward the direction close to the side panel, and the adjustment member drives the push rod to move toward the direction close to the protective frame. The push rod pushes the protective frame to rotate further away from the side panel, so that the protective frame remains in an inclined state away from the side panel, which helps to catch a falling worker; if the worker just presses on the first extrusion bar when leaning against the side panel to rest, the second extrusion bar remains in its original position. When the worker releases the pressed first extrusion bar, the compressed spring pushes the first extrusion bar to slide away from the corresponding side panel, causing the rack to drive the gear to rotate, the reel rotates to rewind the transmission rope, and the transmission rope pulls the protective frame to rotate toward the corresponding side panel for reset, reducing the occupied space and facilitating adaptation to different situations.

[0024] The cam is connected to the second sliding member by a spring, and the cam has a first end connected to the second sliding member and a second end connected to the second sliding member by a spring.

[0025] By adopting the above technical solution, when the second extrusion bar slides toward the direction close to the corresponding side panel, the second extrusion bar presses the opening and closing plate to rotate downward. At this time, the tension of the second extrusion bar on the thin rope is reduced, and the push rod slides toward the direction close to the protective frame under the action of the tension spring, so that the push rod continues to push the protective frame to rotate in the direction away from the corresponding side panel. Since the tension of the tension spring is greater than the push force of the spring, the protective frame can be prevented from rotating toward the side panel under the pull of the transmission rope, which helps the protective net catch the falling workers and improves safety.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. Workers stand in the hanging basket and use the driving parts to drive the hanging arm to move the hanging basket in the horizontal direction inside the sound barrier, which is convenient for workers to install or adjust the transparent PC panels at different positions of the sound barrier, saving workers the time of climbing and moving ladders or scaffolding, and helping to improve work efficiency;

[0028] 2.

Workers do not need to climb the scaffolding to enter the hanging basket at a certain height, which can save a certain amount of time, help improve work efficiency, and improve safety.

The ends of the connecting ropes 41 on both sides of the sliding arm 201 away from the sliding arm 201 are both wound around the corresponding first winch 42 and are wound in opposite directions. A support plate 23 is fixed on the side of the mounting rail 1 away from the first winch 42, and a guide pulley 6 is fixedly mounted on the support plate 23. The connecting rope 41 between the side of the sliding arm 201 away from the first winch 42 and the first winch 42 is slidably overlapped on the guide pulley 6.

[0040] During use, the mounting rail 1 is installed on the top of the inner side of the sound barrier, and the worker stands on the base plate 31. Then, the first winch 42 on the mounting rail 1 is started at the same time. The two first winches 42 simultaneously reel in the connecting rope 41 on the same side and unreel the connecting rope 41 on the other side. The connecting rope 41 can pull the sliding arm 201 to slide in the same direction along the length direction of the mounting rail 1, so that the worker can install or adjust the transparent PC board in sequence along the length direction of the sound barrier, saving the workers' time in climbing mobile scaffolding or ladders, and improving work efficiency to a certain extent.

One end of the pull rope 51 is fixedly connected to the side of the boom 32 close to the connecting arm 202, and the other end is wound around the second winch 52 in the corresponding slide groove 24.

[0042] Reference Figure 2 and Figure 4 A slot 25 is defined on the side of the connecting arm 202 away from the base plate 31. A guide rod 26 is inserted into the slot 25. The longitudinal cross-section of the guide rod 26 is an inverted L-shaped. A guide bar 27 is fixed to the side of the suspension rod 32 near the guide rod 26. The length of the guide bar 27 is perpendicular to the length of the suspension rod 32 and parallel to the depth of the slot 25. The guide rod 26 has a strip hole 28 for the guide bar 27 on the corresponding suspension rod 32 to slide through. The length of the strip hole 28 is arranged in the vertical direction and is perpendicular to the plane of the strip hole 28.

At this time, the hanging basket 3 is on the ground. Then the worker enters the hanging basket 3 and moves the guide rod 26 toward the direction close to the slot 25, so that the guide rod 26 is plugged into the corresponding slot 25, and the guide bar 27 on the corresponding suspension rod 32 passes through the bar hole 28 of the guide rod 26. Then start the second hoist 52 to rewind the pull rope 51, and the pull rope 51 pulls the corresponding suspension rod 32 to slide toward the direction close to the mounting rail 1. Due to the guide bar 27 and the bar hole 28 slides together to guide the rise of the boom 32, so that the basket 3 is not prone to violent shaking. Then the boom 32 gradually enters the corresponding slide groove 24, and the basket 3 is moved to the required height, so that the socket 30 is aligned with the pin 29, and then the pin 29 is passed through the corresponding socket 30, which can reduce the load of the second winch 52, thereby transporting the basket 3 to a certain height, making it convenient for workers in the basket 3 to install or adjust the transparent PC board of the sound barrier. There is no need for workers to enter the basket 3 by climbing the scaffolding, which can save a certain amount of time and improve work efficiency. At the same time, it is highly safe.

When the hanging rope 9 is in a tensioned state, the angle between the side of the protective frame 7 close to the corresponding side panel 33 and the corresponding side panel 33 is 60°-90°. In this embodiment, when the hanging rope 9 is in a tensioned state, the angle between the side of the protective frame 7 close to the corresponding side panel 33 and the corresponding side panel 33 is 70°.

[0046] Reference Figure 4 A first adsorption component is fixedly connected to one side of the protective frame 7 close to the corresponding side panel 33, and the first adsorption component includes an iron sheet 11 fixedly connected to one side of the protective frame 7 close to the corresponding side panel 33; a second adsorption component is fixedly provided on one side of the side panel 33 close to the corresponding protective frame 7, and the second adsorption component includes a magnet 12 fixedly connected to one side of the side panel 33 close to the corresponding protective frame 7, the magnet 12 and the iron sheet 11 are located between the hanging ropes 9 on both sides, and the magnet 12 and the iron sheet 11 are located at the end of the protective frame 7 away from the rotating shaft 34, the magnet 12 is used to be adsorbed and cooperated with the iron sheet 11 on the corresponding protective frame 7, and the adsorption force between the magnet 12 and the corresponding iron sheet 11 is greater than the gravity of the protective frame 7. In other embodiments, the iron sheet 11 provided on the protective frame 7 and the magnet 12 provided on the side panel 33 can be replaced with Velcro, and the relative fixation or separation between the protective frame 7 and the corresponding side panel 33 can also be achieved through the adhesion between the Velcro.

[0047] Reference Figure 4 and Figure 5 The side panel 33 is provided with a mounting groove 35 on a side away from the protective frame 7. The mounting groove 35 is located at the upper end of the corresponding side panel 33. A first extrusion strip 10 is slidingly arranged in the mounting groove 35. The cross section of the first extrusion strip 10 is a rectangular frame. The length direction of the first extrusion strip 10 is parallel to the length direction of the corresponding side panel 33. The sliding direction of the first extrusion strip 10 is perpendicular to the plane of the corresponding side panel 33. The distance from the side of the first extrusion strip 10 away from the corresponding protective frame 7 to the side of the corresponding side panel 33 close to the protective frame 7 is greater than the thickness of the corresponding side panel 33, so that part of the first extrusion strip 10 is located outside the mounting groove 35. A transmission member is provided on the side panel 33. The transmission member is used to separate the magnet 12 and the corresponding iron sheet 11 when the first extrusion strip 10 slides toward the direction close to the corresponding side panel 33.

[0048] Reference Figure 5 and Figure 6 The transmission member includes an abutment rod 13 fixedly connected to the side of the first extruded strip 10 close to the side plate 33. Two abutment rods 13 are symmetrically arranged along the midline of the first extruded strip 10. The length direction of the abutment rod 13 is perpendicular to the plane where the corresponding side plate 33 is located. The abutment rod 13 is slidably passed through the side of the corresponding side plate 33 close to the protective frame 7. The end of the abutment rod 13 away from the first extruded strip 10 is used to abut the protective frame 7 on the corresponding side.

[0049] In the initial state, the iron sheet 11 on the protective frame 7 is attracted and matched with the magnet 12 on the corresponding side panel 33, and the protective frame 7 is now in a folded and tilted state. When a worker falls from a side panel 33, he or she will first press the first extrusion bar 10 on the corresponding side panel 33, pushing the first extrusion bar 10 to slide in the direction close to the corresponding side panel 33. The first extrusion bar 10 drives the corresponding abutment rod 13 to slide in the direction close to the protective frame 7, so that the abutment rod 13 pushes the protective frame 7 to rotate away from the side panel 33, causing the magnet 12 and the corresponding iron sheet 11 to separate. At this time, the protective frame 7 rotates in the direction away from the corresponding side panel 33 under the action of gravity, and the lifting rope 9 is gradually tightened, causing the protective frame 7 to rotate to a tilted state. The lifting rope 9 limits the protective frame 7, thereby helping the protective net 8 to catch the falling worker, thereby improving safety to a certain extent.

[0050] Reference Figure 5 and Figure 6 A spring 14 is provided in the mounting groove 35 for pushing the first extrusion strip 10 to slide in a direction away from the side plate 33. The spring 14 corresponds to the abutment rod 13 one by one. The spring 14 is movably sleeved on the corresponding abutment rod 13. The elastic force of the spring 14 is greater than the gravity of the protective frame 7. One end of the spring 14 is fixed to a side of the first extrusion strip 10 close to the side plate 33, and the other end is fixed to the bottom wall of the mounting groove 35. A cavity 36 is provided in the side plate 33, and the cavity 36 is located below the mounting groove 35. The cavity 36 is communicated with the mounting groove 35. Two racks 15 are fixed relatively to the bottom wall of the first extruded strip 10. The two racks 15 are symmetrical along the center line of the first extruded strip 10.

A gear 16 is rotatably provided in the cavity 36, and the rotation axis of the gear 16 is perpendicular to the sliding direction of the first extruded strip 10. The gear 16 and the rack 15 correspond one to one. The gear 16 is located below the corresponding rack 15, and the gear 16 is meshed with the corresponding rack 15. A reel 17 is coaxially provided on the gear 16, and the reel 17 rotates in the cavity 36. A transmission rope 18 is wound around the reel 17, and the transmission rope 18 extends downward and slides through a side of the corresponding side plate 33 close to the protective frame 7 and is fixed to the lower end of the protective frame 7. When the first extruded strip 10 slides in the direction close to the corresponding side plate 33, the reel 17 unwinds the transmission rope 18.

The length direction of the second extruded strip 19 is parallel to the length direction of the corresponding side panel 33, and the sliding direction of the second extruded strip 19 is set in the vertical direction. A push rod 20 is slidably penetrated at the lower end of the side panel 33, and the push rod 20 passes through the cavity 36. Three push rods 20 are arranged along the length direction of the side panel 33. The sliding direction of the push rod 20 is perpendicular to the plane of the corresponding side panel 33. A disc 38 is fixed on the side of the push rod 20 close to the protective net 8. The diameter of the disc 38 is larger than the side length of the mesh of the protective net 8, so that the disc 38 is not easy to enter the mesh of the protective net 8. The disc 38 is used to abut against the protective net 8. An adjusting member 21 is provided in the cavity 36. The adjusting member 21 is used to drive the push rod 20 to slide when the second extrusion strip 19 slides. When the second extrusion strip 19 slides toward the direction close to the side panel 33, the push rod 20 slides toward the direction close to the protective frame 7.

[0052] Reference Figure 5 and Figure 6 In order to facilitate the sliding of the push rod 20 toward the direction close to the protective net 8, the adjusting member 21 includes a tension spring 211, a thin rope 212, an opening and closing plate 213 and a torsion spring 214. The tension spring 211 corresponds to the push rod 20 one by one. The tension spring 211 is sleeved on the corresponding push rod 20. One end of the tension spring 211 is fixedly connected to the side of the push rod 20 away from the protective frame 7, and the other end is fixedly connected to the inner wall of the cavity 36 close to the protective frame 7. The tension spring 211 is used to pull the corresponding push rod 20 to slide toward the direction close to the protective frame 7. The tension of the tension spring 211 The force is greater than the thrust of the spring 14; the bottom wall of the second extrusion strip 19 is fixedly connected with a fixed ball 39, the fixed ball 39 corresponds one to one with the push rod 20, the diameter of the fixed ball 39 is greater than the width of the second extrusion strip 19, the thin rope 212 corresponds one to one with the fixed ball 39, one end of the thin rope 212 is fixedly connected to the corresponding fixed ball 39, and the other end slides out of the side of the side panel 33 away from the protective frame 7 and is fixedly connected to the side of the corresponding push rod 20 away from the protective frame 7. The thin rope 212 is used to pull the corresponding push rod 20 to slide in the direction away from the protective frame 7.

[0053] Reference Figure 5 and Figure 6, the opening and closing plate 213 is hinged in the cavity 36, the opening and closing plate 213 is located between the first extrusion strip 10 and the push rod 20, and a rotating rod 22 is fixedly provided on the opening and closing plate 213. The rotating rod 22 is located on the side of the cavity 36 close to the protective frame 7, and the rotating rod 22 rotates in the cavity 36. The rotation axis of the rotating rod 22 is parallel to the length direction of the corresponding side plate 33. The second extrusion strip 19 is located on the side of the opening and closing plate 213 away from the rotating rod 22. The torsion spring 214 is sleeved on the rotating rod 22. One end of the torsion spring 214 is fixedly connected to the inner wall of the cavity 36, and the other end is fixedly connected to the opening and closing plate 213. The torsion spring 214 is used to drive the opening and closing plate 213 to maintain a horizontal position. The fixed ball 39 is located above the opening and closing plate 213, and the torsion force of the torsion spring 214 is greater than that of the second extrusion strip 19, the tension of the tension spring 211 and the gravity of the fixed ball 39; the sum of the length of the opening and closing plate 213 in the rotation direction perpendicular to the rotating rod 22 and the diameter of the fixed ball 39 is greater than the width of the cavity 36, and the sum of the length of the opening and closing plate 213 in the rotation direction perpendicular to the rotating rod 22 and the width of the lower end of the second extrusion strip 19 is adapted to the width of the cavity 36, so that when the opening and closing plate 213 is in a horizontal state, the lower end of the second extrusion strip 19 can pass through the gap between the side of the opening and closing plate 213 away from the rotating rod 22 and the inner wall of the cavity 36, thereby facilitating the resetting of the second extrusion strip 19 and the fixed ball 39; when the fixed ball 39 is located above the opening and closing plate 213 and the opening and closing plate 213 is in a horizontal state, the disc 38 is close to the corresponding side plate 33.

[0054] When a worker falls from a side panel 33, he will first press the first extrusion bar 10 on the corresponding side panel 33. The first extrusion bar 10 drives the abutment rod 13 to slide toward the direction close to the protective frame 7. The abutment rod 13 pushes the protective frame 7, so that the magnet 12 and the corresponding iron sheet 11 are separated. At the same time, the rack 15 drives the corresponding gear 16 to rotate, so that the reel 17 unwinds the transmission rope 18. At this time, the protective frame 7 rotates in the direction away from the corresponding side panel 33 under the action of gravity; then the body of the falling worker presses on the corresponding side panel 33. 3, the weight of the person is greater than the torsion of the torsion spring 214, causing the second extrusion bar 19 to slide toward the side plate 33, causing the fixed ball 39 to push the opening and closing plate 213 to rotate downward, reducing the tension on the string 212, and the stretched tension spring 211 pulls the push rod 20 to slide toward the protective frame 7, and the disc 38 pushes the protective net 8 and the protective frame 7 to rotate away from the side plate 33. The protective frame 7 remains in a tilted state away from the side plate 33, which helps to catch falling workers and has high safety.

[0055] If a worker simply presses the first extrusion bar 10 while resting against the side panel 33, after the worker releases the first extrusion bar 10, the compressed spring 14 pushes the first extrusion bar 10 to slide away from the corresponding side panel 33, causing the rack 15 to drive the gear 16 to rotate, and the reel 17 to rotate and rewind the transmission rope 18. The transmission rope 18 pulls the protective frame 7 to slide toward the corresponding side panel 33 to reset, so that the iron sheet 11 on the protective frame 7 and the magnet 12 on the side panel 33 are attracted and matched, reducing the space occupied by the protective frame 7 and facilitating its adaptation to different situations. Due to the high torsion force of the torsion spring 214, when the worker lightly holds the top of the side panel 33, it is difficult to drive the second extrusion bar 19 to slide.

[0056] Reference Figure 2 The upper end of the second extruded strip 19 is covered with a protective cover 40, and the bottom wall of the protective cover 40 abuts against the corresponding side plate 33. When a worker enters or exits the hanging basket 3, the protective cover 40 is placed on the second extruded strip 19 to prevent the worker from pressing the second extruded strip 19. After the worker enters the hanging basket 3, the protective cover 40 is removed from the second extruded strip 19 to protect the worker.

[0057] The implementation principle of the embodiment of the present application is as follows: when in use, start the second hoist 52 to unwind the pull rope 51, so that the pull rope 51 is long enough, and then fix the mounting rail 1 to the top of the inner side of the sound barrier by bolts or clamps. At this time, the hanging basket 3 is on the ground and the boom 32 is aligned with the connecting arm 202, and the protective cover 40 is respectively covered on the second extruded strips 19 on the four sides. Then the worker enters the hanging basket 3, and then removes the protective cover 40 from the second extruded strip 19, and then moves the guide rod 26 toward the direction close to the slot 25, so that the guide rod 26 is plugged into the corresponding slot 25, and the corresponding boom 32 is on The guide bar 27 passes through the bar hole 28 of the guide rod 26, and then the second winch 52 is started to reel in the pull rope 51. The pull rope 51 pulls the corresponding boom 32 to slide toward the mounting rail 1, and then the boom 32 gradually enters the corresponding slide groove 24, and the hanging basket 3 is moved to the required height, so that the socket 30 is aligned with the pin 29, and then the pin 29 is passed through the corresponding socket 30, and the guide rod 26 is taken out from the corresponding slot 25, so that the bar hole 28 on the guide rod 26 is disengaged from the guide bar 27. The worker stands on the base plate 31 to install or adjust the transparent PC board on the inside of the sound barrier.

[0058] When it is necessary to move the position of the hanging basket 3, the first winches 42 on the two mounting rails 1 are started at the same time. The two first winches 42 simultaneously reel in the connecting rope 41 on the same side and unreel the connecting rope 41 on the other side. The connecting rope 41 can pull the sliding arm 201 to slide in the length direction of the mounting rail 1, so that workers can install or adjust the transparent PC panels in sequence along the length direction of the sound barrier, saving workers' time in climbing mobile scaffolding or ladders, and improving work efficiency to a certain extent.

[0059] The first extrusion bar 10 of the corresponding side plate 33 is pressed by the first extrusion bar 10, and the first extrusion bar 10 drives the abutment rod 13 to push the protection frame 7, so that the magnet 12 and the corresponding iron sheet 11 are separated. At the same time, the rack 15 drives the corresponding gear 16 to rotate, so that the reel 17 unwinds the transmission rope 18. At this time, the protection frame 7 rotates downward under the action of gravity. Then the body of the falling worker presses on the second extrusion bar 19 of the corresponding side plate 33, so that the second extrusion bar 19 slides in the direction close to the side plate 33, so that the fixed ball 39 pushes the opening and closing plate 213 to rotate downward. The fixed ball 39 moves below the opening and closing plate 213, reducing the tension on the thin rope 212. The stretched tension spring 211 pulls the push rod 20 to slide in the direction close to the protection frame 7, and the disc 38 pushes the protection net 8 and the protection frame 7 to rotate in the direction away from the side plate 33, so that the protection frame 7 remains in an inclined state away from the side plate 33, which is helpful to catch the falling worker and has high safety.

[0060] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
