Technical Field
[0001] The present application relates to the technical field of electric power equipment, and in particular to a lifting device that is convenient for high-altitude live-line operations. Background Art
[0002] During the power construction process, workers need to inspect and maintain the lines at high places, so they need to climb. Due to the limitations of the construction site or the lines are too high, the existing elevators cannot meet the actual needs, so a rope lifting device is needed to climb to the high lines.
[0003] like Figure 1 As shown, it is a schematic diagram of an existing lifting device, and its working process is: before climbing, first hang the insulating rope 103 on the high line through the drone, then connect the safety belt of the staff to the hanging ring 101, and finally turn the throttle handle 102. The lifting device 1 can bring the staff to a high altitude through the cooperation with the insulating rope 103, and finally carry out the line maintenance. Of course, the staff can also leave the lifting device 1 and climb to the line for maintenance. However, the existing lifting device 1 has the following shortcomings: after being lifted to the high line, since the lifting device 1 and the line are only suspended by the insulating rope 103, the stability is poor (i.e., it is easy to shake). Whether it is directly inspecting the line on the lifting device 1 or climbing from the lifting device 1 to the line, it is very inconvenient; for this reason, a lifting device that is convenient for high-altitude live work is proposed to solve the above technical problems.

[0024] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0025] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and cannot be understood as limiting the specific scope of protection of the present application.
[0026] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.
[0027] One of the preferred embodiments of the present application is as follows: Figures 1 to 6 As shown, a lifting device convenient for high-altitude live-wire work includes a lifter 1, a ladder 2 and a hook portion 3, wherein the ladder 2 is installed on the side of the lifter 1 and is a retractable structure, and the hook portion 3 is installed on the top of the ladder 2.
[0028] It can be understood that when the staff ascends to the high line through the lifter 1, the escalator 2 can be used at this time: the escalator 2 is extended upward so that the hook part 3 on the unfolded escalator 2 and the line are suspended and matched, so that the lifter 1 can be further limited and the stability is greatly improved; at the same time, the unfolded escalator 2 can also assist the staff to climb, so that the staff can climb to the line more conveniently.
[0029] Further, such as Figure 4 and Figure 5 As shown, a roller 5 can be provided at the inner upper end of the hook part 3, and the roller 5 can cooperate with the line. It should be known that in actual power construction, for safety reasons, the position where the lifter 1 rises must be at a certain horizontal distance from the position where the line is inspected, so the staff still needs to move a distance after rising. At this time, the staff can grasp one of the lines to apply force, so that the lifter 1 can move and adjust under the cooperation of the roller 5 and the suspended line, that is, it can drive the staff to move horizontally, further improving the convenience.
[0030] Since the hook portion 3 and the line are suspended in cooperation, the two can be easily separated under the action of external force, thereby making the device less safe.
[0031] Therefore, in order to solve the above technical problems, in one embodiment of the present application, Figure 5 As shown, a locking member 6 is provided in the hook portion 3. It is understandable that after the hook portion 3 is matched with the line, the opening 7 of the hook portion 3 can be kept in a closed state by the locking member 6, thereby ensuring that the match between the hook portion 3 and the line is more stable, avoiding separation due to external force, and thus improving the safety of the device.
[0032] Specifically, Figure 5 As shown, the locking member 6 includes a baffle 601, which is elastically mounted on the first end of the opening 7. It is understandable that the baffle 601 can be pressed against the second end of the opening 7 under the action of elastic force, so that the opening 7 is in a closed state.
[0033] Of course, there are many ways to install the baffle 601, including but not limited to the following two:
[0034] Method 1: If Figure 5As shown, the right end of the baffle 601 can be rotatably mounted at the first end (i.e., the right end) of the opening 7 through a torsion spring. Specifically, in the normal state, the left end of the baffle 601 will abut against the second end (i.e., the left end) of the opening 7 under the action of elastic force, and at this time, the baffle 601 can only rotate upward and cannot rotate downward, so that the opening 7 is in a closed structure, and the circuit located inside the hook portion 3 will not become detached. When detachment is required, only rotate the baffle 601 upward to open the opening 7, and at this time, the circuit can be removed from the opening 7.
[0035] Method 2 (not shown): The baffle 601 can be elastically and horizontally slidably arranged at the first end (i.e., the right end) of the opening 7 through a spring. Specifically, in the normal state, the left end of the baffle 601 will abut against the second end (i.e., the left end) of the opening 7 under the action of elastic force, thereby realizing the closure of the opening 7. When demolding is required, move the baffle 601 to the right to open the opening 7.
[0036] It should be noted that for Method 1, its structural stability and convenience are better. For example, when hanging, the baffle 601 can be rotated and opened by the acting force of the circuit itself; while in Method 2, the staff needs to manually move the baffle 601 during both the hanging and detachment processes; therefore, Method 1 is preferably adopted in this application. Of course, both methods can meet the actual requirements, and those skilled in the art can make a choice according to the actual situation.
[0037] In one embodiment of the present application, as Figure 4 shown, the escalator 2 includes a plurality of U-shaped frames 201, and the plurality of U-shaped frames 201 are distributed from bottom to top and their sizes decrease, and adjacent U-shaped frames 201 are sleeved and slidably arranged; as the name implies, the U-shaped frame 201 has a "U" - shaped structure.
[0038] Specifically, as Figure 4 shown, assuming there are four U-shaped frames 201, the uppermost (i.e., the fourth) U-shaped frame 201 has the smallest size, and the third U-shaped frame 201 is sleeved and slidably arranged at two brackets of the fourth U-shaped frame 201. Similarly, between adjacent U-shaped frames 201, the lower U-shaped frame 201 is sleeved and slidably arranged at two brackets of the upper U-shaped frame 201, and the lowermost (i.e., the first) U-shaped frame 201 is fixedly installed on the side of the lifter 1. It can be understood that at this time, the telescopic escalator 2 is similar to a telescopic rod structure.
[0039] Furthermore, in order to improve the stability of the escalator 2 after contraction, as Figure 3 shown, a limit component 4 can be provided on the lifter 1; when the escalator 2 contracts, the limit component 4 can lock the escalator 2.
[0040] Specifically, as Figure 3 As shown, the limiting assembly 4 includes a limiting plate 401, which is horizontally rotatably mounted on the top of the lifter 1; when the escalator 2 is locked, the limiting plate 401 can be rotated until it abuts against the top of the escalator 2; when the escalator 2 is in use, the limiting plate 401 can be reversed until it is away from the escalator 2. Of course, in order to improve the stability of the limiting plate 401 when limiting, the limiting plate 401 can be rotatably mounted on the top of the lifter 1 through a damping shaft, that is, when the limiting plate 401 stops rotating, the limiting plate 401 can remain stationary through the damping force of the damping shaft.
[0041] In this embodiment, Figure 6 As shown, a pair of escalators 2 can be provided, that is, two escalators 2 are symmetrically distributed up and down. It can be understood that the upper escalator 2 can be extended upward, and the lower escalator 2 can be extended downward, that is, the two escalators are extended back to back to form a long ladder structure, which can make it easier for workers to climb and further improve the climbing efficiency.
[0042] In addition, a hook portion 3 can also be provided on the upper side of the lower escalator 2, so that the two escalators 2 can be suspended and coordinated with the line at the same time after being extended. Of course, the two escalators 2 are in a nearly horizontal state at this time, that is to say, the two escalators 2 are suspended between two almost parallel lines at this time, and then the entire lifter 1 is equivalent to a "line bridge". For example, the staff can sit on the "line bridge" to operate or take a rest and adjust.
[0043] The working principle of the utility model is:
[0044] First, operate the drone to hang the insulating rope 103 on the high line, and then connect the safety belt on the staff to the hanging ring 101. For safety reasons, a safety rope can be hung on the line by the drone, and the staff is connected to the safety rope to prevent the insulating rope 103 from breaking during lifting.
[0045] Of course, at the bottom of the actual lifter 1, a support frame is also installed, and the staff can sit on the support frame and put their feet on the support frame; when ascending, the staff holds the throttle handle 102 and starts the lifter 1 through the throttle handle 102. The lifter 1 can bring the staff to a high altitude by cooperating with the insulating rope 103. When it rises to a suitable height, the staff can stretch out the escalator 2 and suspend it with the high-altitude line through the hook part 3, so that the lifter 1 can be further limited and the stability can be greatly improved; at the same time, the unfolded escalator 2 can also assist the staff in climbing, which is convenient for subsequent line maintenance operations.
[0046] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought. The scope of protection claimed by the present application is defined by the attached claims and their equivalents.
