[0001] The invention relates to the technical field of electric power equipment, and in particular to a vertical ladder with a working platform. Background Art

[0002] Climbing is one of the daily tasks of maintenance personnel, and the main tool used for climbing is the ladder. Traditional ladders do not have the function of material transportation. Therefore, in order to avoid lack of tools during aerial operations, maintenance personnel often need to carry a tool bag to climb the ladder. Due to the messy objects in the tool bag, maintenance personnel often need to hold the ladder with one hand and search for the required tools in the tool bag with the other hand, which is very time-consuming and laborious, and there is a greater risk of falling, which greatly threatens the life safety of maintenance personnel.

[0003] Therefore, it is necessary to improve the existing vertical ladder to solve the problem that it does not have the material transportation function and reduce the risk of maintenance personnel falling when searching for tools. Summary of the invention

[0037] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0039] See also Figure 1 to Figure 5, this embodiment provides a vertical ladder with a working platform, including a vertical ladder body and a working platform.

[0040] The vertical ladder body comprises two vertical rods 1 and a plurality of horizontal rods 2 disposed transversely between the two vertical rods 1 .

[0041] The working platform includes a fixed plate 3 fixed on the main body of the straight ladder, a working table 4 rotatably connected to the fixed plate 3, a storage plate 5 located below the working table 4 and slidably connected to the working table 4, and a winch 6 fixed to one end of the working table 4; the storage plate 5 can slide toward the direction approaching the fixed plate 3 to the bottom of the working table 4 or slide toward the direction away from the fixed plate 3 to the outside of the working table 4.

[0042] It is understandable that the rotatable connection between the work surface 4 and the fixed plate 3 can realize the storage function of the work surface 4 and save space.

[0043] Specifically, on the one hand, a winch 6 is fixed on the work surface 4, and the pull rope 601 of the winch 6 extends downward to the ground to realize the up and down transportation of materials, avoiding the operation and maintenance personnel to go up and down many times to get tools; on the other hand, after climbing the ladder, the operation and maintenance personnel can put the tools they need to use on the work surface 4 before working, so as to avoid the situation of searching for tools with one hand during the operation, which greatly reduces the risk of falling of the operation and maintenance personnel; furthermore, in order to improve the practicality of the work platform, the straight ladder with the work platform is also provided with a slidable and retractable storage board 5. For example, when a laptop is to be used for debugging in the air, the work surface 4 is already full of tools, the storage board 5 can be pulled out, and then the laptop is placed on the storage board 5. After use, the storage board 5 can be pushed back, which is convenient for operation and does not take up space.

[0044] The work platform further includes a hinge 7, a stopper 8 and a fixing bolt 9. The hinge 7 is located above the work surface 4 and is fixedly connected to the fixing plate 3 and the work surface 4 respectively. The stopper 8 is located below the work surface 4 near one end of the fixing plate 3. The fixing bolt 9 penetrates the work surface 4 and is threadedly connected to the stopper 8 downward.

[0045] Specifically, the hinge 7 can realize a large-angle rotation connection between the work surface 4 and the fixed plate 3. The limit block 8 provided below the work surface 4 can limit the rotation angle of the work surface 4 and the fixed plate 3, thereby preventing the work surface 4 from tilting downward.

[0046] Furthermore, the work surface 4 is provided with a strip-shaped through slot 401 perpendicular to the fixing plate 3 , and the fixing bolt 9 passes through the strip-shaped through slot 401 and can approach or move away from the fixing plate 3 along the strip-shaped through slot 401 .

[0047] It should be noted that adjusting the position of the fixing bolt 9 along the strip-shaped through slot 401 is equivalent to adjusting the position of the stopper 8. When the stopper 8 is away from the fixing plate 3, the maximum angle between the work surface 4 and the fixing plate 3 can be an obtuse angle, and when the stopper 8 is close to the fixing plate 3, the maximum angle between the work surface 4 and the fixing plate 3 is an acute angle to ensure that objects will not slide down from the work surface 4 to the fixing plate 3. Once the position of the stopper 8 changes, the maximum angle between the work surface 4 and the fixing plate 3 changes. Therefore, the setting of the long strip-shaped through slot 401 can adjust the inclination angle of the work surface 4.

[0048] Preferably, the limit block 8 is adjusted so that the maximum angle between the work surface 4 and the fixing plate 3 is a right angle or an acute angle.

[0049] Optionally, the height of the upper portion of the fixing plate 3 is higher than the work surface 4 to form an insulating guardrail 301 .

[0050] Specifically, the insulating guardrail 301 can prevent objects from sliding off the end of the work surface 4 close to the fixing plate 3 .

[0051] In this embodiment, the work surface 4 is provided with a plurality of through holes 402 for inserting tools.

[0052] Specifically, the through hole 402 can facilitate the insertion of a tool from a vertical direction.

[0053] Optionally, an opening slot 403 for inserting a tool is provided on the work surface 4 , and the opening slot 403 extends from a side of the work surface 4 away from the winch 6 toward a direction close to the winch 6 .

[0054] Specifically, the open slot 403 can facilitate the insertion of the tool from a horizontal direction.

[0055] Preferably, an end of the work surface 4 away from the fixing plate 3 is provided with a concave arc portion 404 .

[0056] Specifically, the arc-shaped portion 404 can make room for the body of the operation and maintenance personnel, allowing the human body to be closer to the main body of the elevator, thereby preventing the operation and maintenance personnel from falling due to leaving the main body of the elevator.

[0057] In this embodiment, a near-electricity protector 10 is provided inside the vertical rod 1 .

[0058] Specifically, the near-electricity protector 10 is a personal protection device commonly used by power personnel. When the distance between the near-electricity protector 10 and the live area is less than the safe distance, the near-electricity protector 10 will emit a buzzer to remind the operation and maintenance personnel. Optionally, the safety level of the near-electricity protector 10 is adjustable, and different voltage levels can be selected through the gear position to ensure the accuracy of the corresponding safety distance alarm value when working at the voltage level.

[0059] Optionally, a connecting joint 11 fixedly connected to the rotating shaft of the hoist 6 is provided on the outside of the hoist 6 .

[0060] Preferably, the connecting joint 11 is a hexagonal joint.

[0061] In this embodiment, the winch 6 may include a housing, a rotating shaft located inside the housing and rotatably connected to the housing, a pull rope 601 having one end fixed to the middle of the rotating shaft, and a connecting joint 11 fixed to the end of the rotating shaft for driving the rotating shaft to rotate; the connecting joint 11 is located outside the housing and coaxial with the rotating shaft. The connecting joint 11 provided by the present invention is also externally connected to an electric mechanism, such as a motor or a hand drill, etc., and the pull rope 601 can be retracted and extended by starting the electric mechanism.

[0062] The vertical ladder with a working platform provided in this embodiment has the following advantages:

[0063] ① In this embodiment, the work platform is made of insulating plates, and the insulation level reaches above 10kV. The hinge 7 and the limit block 8 allow the work surface 4 and the fixed plate 3 to be fixedly adjusted within the folding range of 0 to 90 degrees, so that the work surface 4 can remain horizontal when the main body of the ladder is at different inclination angles;

[0064] ② The winch 6 is mainly used to extract heavy objects, and uses an external electric tool such as a hand drill to drive the rotating shaft through the connecting joint 11. The winch 6 is installed at one end of the work surface 4, and the other end of the pull rope 601 is equipped with a hawk hook. The winch 6 provides a stainless steel twisted rope with a safe load-bearing capacity of 35kg and a maximum load-bearing capacity of 250kg as the pull rope 601. The maximum extension length of the pull rope 601 is 6 meters; a rechargeable electric drill or other electric mechanism is used in conjunction with the connecting joint 11 to rotate the rotating shaft of the winch 6 to realize the retraction and release of the stainless steel twisted rope, and realize electric lifting up and down on the ladder;

[0065] ③ The working platform is equipped with an insulating guardrail 301, which can prevent electric shock and prevent tools from falling;

[0066] ④ The working platform is equipped with a retractable storage board 5, so that a laptop can be placed on the working platform, providing convenience for debugging parameters and programs on the ladder;

[0067] ⑤ A tool bag hook is provided under the work surface 4, on which the tool bag can be hung to avoid the operation and maintenance personnel having to carry it on their shoulders, which can not only reduce the burden but also improve the safety of aerial operations;

[0068] ⑥ Through holes 402 of various diameters may be provided to accommodate different tools. Optionally, 10 holes are provided on the work surface 4, 5 small holes with a diameter of 7 mm, and 5 large holes with a diameter of 26 mm. The small holes are mainly used to place frequently used tools such as screwdrivers and hexagonal keys, and the large holes are used to place frequently used tools such as wrenches, pliers, and pressure pliers.
