Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of the hole protection, and specifically relates to a multifunctional foldable guardrail. BACKGROUND

[0002] A wind turbine, also known as a windmill or windmill, is a power device that converts wind energy into electrical energy. Its working principle is based on the process of converting wind energy into mechanical energy, and then converting mechanical energy into electrical energy. Specifically, when the wind blows the blades of the wind turbine, the blades begin to rotate, and then drive the rotor inside the generator to rotate. The rotation of the rotor produces electrical energy through electromagnetic induction principle, and finally outputs usable alternating current or direct current.

[0003] At present, in the wind turbine cabin, a guardrail is usually arranged around the lifting hole to protect the workers during lifting operation. As the wind turbine cabin becomes more and more compact, the hole cover on the cabin cover and the cover plate on the platform plate need to be closed when not in use to serve as a personnel passage. However, the lifting hole guardrails in the prior art are mostly simple in structure, not convenient for quick disassembly when the lifting hole is not in use and quick installation when in use, and have single protection function, reducing the practicability of the device. Therefore, in view of the above technical problems, a multifunctional foldable guardrail is proposed. SUMMARY

[0004] In view of the deficiencies in the prior art, the utility model provides a multifunctional foldable guardrail, which is convenient for quick disassembly when the lifting hole is not in use and quick installation when in use, and can protect the generator side to avoid the workers stepping into the gap behind the generator, improving the practicability of the device.

[0005] The multifunctional foldable guardrail comprises:

[0006] The side rail is provided with two groups, one end of each group of the side rail is rotatably provided with a fixed column, the bottom end of each group of the fixed column is fixed on the rear rack platform, and the other end of each group of the side rail is rotatably provided with a movable column;

[0007] The short rail is provided with two groups, one end of each group of the short rail is rotatably arranged on each group of the movable column; and

[0008] The fixed assembly is arranged on each group of the short rail and can be connected with the rear rack platform, and adjusting the connection position of the fixed assembly and the rear rack platform can make each group of the side rail and each group of the short rail have a first state located between the generator and the lifting hole cover plate and a second state that each group of the side rail is located at both ends of the lifting hole cover plate and each group of the short rail is located on the side away from the generator of the lifting hole cover plate.

[0009] The multifunctional foldable guardrail has the following advantages:

[0010] When the lifting hole is not used, the connection between the fixing assembly and the rear rack platform is cancelled, and then the two groups of side rails are rotated in the same direction, and the rotation of the two groups of side rails drives the rotation of the two groups of short rails. When the two groups of side rails and the two groups of short rails are located between the generator and the lifting hole cover plate, the fixing assembly is connected with the rear rack platform again. At this time, the protection of the lifting hole can be cancelled. Conversely, by cancelling the connection between the fixing assembly and the rear rack platform, and then rotating the two groups of side rails in the opposite direction, the reverse rotation of the two groups of side rails drives the reverse rotation of the two groups of short rails. When the two groups of side rails are located at both ends of the lifting hole cover plate, and the two groups of short rails are located away from the generator side of the lifting hole cover plate, the fixing assembly is connected with the rear rack platform again. At this time, the protection of the lifting hole can be carried out. It is convenient to quickly disassemble when the lifting hole is not used and quickly install when it is used. When the two groups of side rails and the two groups of short rails are located between the generator and the lifting hole cover plate, the two groups of side rails and the two groups of short rails can protect the generator side, avoid the staff stepping into the gap behind the generator, and improve the practicability of the device.

[0011] In one embodiment, the fixing assembly includes a latch; the other end of the two groups of short rails is provided with the latch which can slide in the vertical direction, and the top surface of the rear rack platform is provided with two groups of first pin holes located between the generator and the lifting hole cover plate and located at one end of the lifting hole cover plate. The top surface of the rear rack platform is provided with two groups of second pin holes located away from the generator side of the lifting hole cover plate. The two groups of latches can be selectively inserted into the two groups of first pin holes or the two groups of second pin holes. By moving the two groups of latches upward or downward to make the two groups of latches and the two groups of first pin holes or the two groups of second pin holes insert or separate, the two groups of side rails and the two groups of short rails can be fixed or the fixation of the two groups of side rails and the two groups of short rails can be cancelled. The operation is convenient and fast.

[0012] In one embodiment, the two groups of short rails are provided with a fixing sleeve, and the bottom end of the latch can slide through the fixing sleeve in the vertical direction. By providing the fixing sleeve, the stability of the latch sliding in the vertical direction can be improved, and the latch can be taken out of the fixing sleeve by moving upward, which facilitates the separate replacement of the damaged latch and reduces the use cost of the device.

[0013] In one embodiment, the top end of the two groups of latches is provided with a finger buckle. By providing the finger buckle, the staff can hook their fingers in the finger buckle to drive the latch to move upward, which is convenient to move upward and is not easy to slip.

[0014] In one of the embodiments, one end of the side rail is provided with two groups of first connecting sleeves, the two groups of first connecting sleeves are rotatably sleeved on the fixed column, the other end of the side rail is provided with two groups of second connecting sleeves, and the two groups of second connecting sleeves are rotatably sleeved on the movable column.

[0015] In one of the embodiments, the two groups of side rails are provided with limiting blocks, and when the two groups of short rails are away from the generator side, the two groups of limiting blocks abut against the inner sides of the two groups of short rails to limit the inward rotation of the two groups of short rails. The setting of the limiting blocks enables the two groups of short rails to only rotate outwardly to be opened, avoiding the interference between the short rails and the lifting operation.

[0016] In one of the embodiments, the two groups of short rails are respectively detachably connected with the two groups of movable columns. The separate replacement of the short rails after damage is facilitated, and the use cost of the device is reduced.

[0017] In one of the embodiments, one end of each of the two groups of short rails is provided with two groups of connecting assemblies, the connecting assembly comprises two groups of semicircular sleeves, one group of the semicircular sleeves is connected with the short rail, the two groups of semicircular sleeves can be sleeved on the movable column, and the two ends are connected through bolts. The two groups of semicircular sleeves can be separated by disassembling the bolts on the two groups of semicircular sleeves, so that the short rail can be conveniently disassembled from the movable column, and the disassembly of the short rail is facilitated.

The following embodiments are only used to more clearly illustrate the technical scheme of the utility model, and therefore only serve as examples, and cannot limit the protection scope of the utility model.

[0030] Please refer to Figures 1 to 3 A multifunctional foldable guardrail in an embodiment includes a side rail 10, a short rail 20, and a fixing assembly.

[0031] The side rail 10 is provided with two groups, and one end of each group of the side rail 10 is rotatably provided with a fixed stand 101. The bottom end of each group of the fixed stand 101 is fixed on the rear rack platform 1, and the other end of each group of the side rail 10 is rotatably provided with a movable stand 102. Specifically, one end of the side rail 10 is provided with two groups of first connecting sleeves 103, and the two groups of first connecting sleeves 103 are rotatably sleeved on the fixed stand 101. The other end of the side rail 10 is provided with two groups of second connecting sleeves 104, and the two groups of second connecting sleeves 104 are rotatably sleeved on the movable stand 102. By connecting the fixed stand 101 and the movable stand 102 through the two groups of first connecting sleeves 103 and the two groups of second connecting sleeves 104, the stability of the connection between the side rail 10, the fixed stand 101, and the movable stand 102 can be improved.

[0032] The short rail 20 is provided with two groups, and one end of each group of the short rail 20 is rotatably arranged on each group of the movable stand 102. The fixing assembly is arranged on the two groups of the short rail 20 and can be connected with the rear rack platform 1. Adjusting the connection position of the fixing assembly and the rear rack platform 1 can make the two groups of the side rail 10 and the two groups of the short rail 20 have a first state of being located between the generator 2 and the lifting hole cover plate 3 and a second state of the two groups of the side rail 10 being located at both ends of the lifting hole cover plate 3 and the two groups of the short rail 20 being located on the side of the lifting hole cover plate 3 away from the generator 2.

[0033] In the above embodiment, when the lifting hole is not used, the protection of the lifting hole can be cancelled by disconnecting the fixing assembly from the rear rack platform 1, then rotating the two sets of side rails 10 and the two sets of short rails 20 to make the two sets of side rails 10 and the two sets of short rails 20 located between the generator 2 and the lifting hole cover plate 3, and then connecting the fixing assembly with the rear rack platform 1. Conversely, the protection of the lifting hole can be achieved by disconnecting the fixing assembly from the rear rack platform 1, then rotating the two sets of side rails 10 and the two sets of short rails 20 in the opposite direction to make the two sets of side rails 10 located at both ends of the lifting hole cover plate 3 and the two sets of short rails 20 located on the side of the lifting hole cover plate 3 away from the generator 2, and then connecting the fixing assembly with the rear rack platform 1. This facilitates quick disassembly when the lifting hole is not used and quick installation when the lifting hole is used. When the two sets of side rails 10 and the two sets of short rails 20 are located between the generator 2 and the lifting hole cover plate 3, the two sets of side rails 10 and the two sets of short rails 20 can protect the side of the generator 2, preventing workers from stepping into the gap behind the generator 2, and improving the practicability of the device. It can be understood that, in normal state, the two sets of side rails 10 and the two sets of short rails 20 are located between the generator 2 and the lifting hole cover plate 3 to protect the side of the generator 2, and the lifting hole cover plate 3 is closed to be used as a personnel passage.

[0034] Please refer to Figures 1 to 3 In an embodiment, the fixing assembly includes a latch 30. The other end of each of the two sets of short rails 20 is provided with the latch 30 which can slide in the vertical direction. The top surface of the rear rack platform 1 is provided with two sets of first pin holes 301 which are located between the generator 2 and the lifting hole cover plate 3 and at one end of the lifting hole cover plate 3. The top surface of the rear rack platform 1 is also provided with two sets of second pin holes 302 which are located on the side of the lifting hole cover plate 3 away from the generator 2. The two latches 30 can be selectively arranged in the two sets of first pin holes 301 or the two sets of second pin holes 302.

[0035] In the above embodiment, the two sets of side rails 10 and the two sets of short rails 20 can be fixed or unfixed by moving the two latches 30 upward or downward to make the two latches 30 inserted into or separated from the two sets of first pin holes 301 or the two sets of second pin holes 302, which is convenient and fast.

[0036] Based on the above embodiment, further, each of the two sets of short rails 20 is provided with a fixing sleeve 201, and the bottom end of the latch 30 can slide through the fixing sleeve 201 in the vertical direction. The fixing sleeve 201 can improve the stability of the latch 30 sliding in the vertical direction. The latch 30 can be taken out of the fixing sleeve 201 by moving the latch 30 upward, which facilitates the separate replacement of the damaged latch 30 and reduces the use cost of the device.

[0037] Further, the top end of the two groups of the latches 30 is provided with a finger buckle 303. By setting the finger buckle 303, the staff can hook the fingers in the finger buckle 303 to drive the latch 30 to move upward, which is convenient and not easy to produce the phenomenon of slipping.
