Description

Technical Field

[0001] The present invention relates to the technical field of power engineering, and particularly to a power maintenance device. Background Art

[0002] Regular maintenance of electricity is very necessary to keep power lines and equipment in a stable and reliable operating state. Since power lines are generally installed at a certain height, especially in outdoor or factory buildings, many are overhead or high-hanging cables; in addition, when maintaining some large power equipment (such as transformers, large-scale electromechanical equipment), a workbench at a corresponding height is also required.

[0003] Currently, for an open environment, a knuckle boom aerial lift is a very convenient auxiliary device. However, it is not applicable to some smaller environments. Therefore, people have specifically designed some power maintenance auxiliary devices with relatively simple structures. Among them, the commonly used one is the scissor lift.

[0004] For example, the patent with the application number 2023105191926 discloses a power maintenance device, including a mobile base, a maintenance platform that can be lifted and installed on the mobile base, and an anti-electric shock mechanism. The patent with the application number 202420581384X discloses a power maintenance device, including a scissor lift vehicle body, a horizontal plate is arranged at the top of the scissor lift vehicle body, a fence is fixedly installed around the top of the horizontal plate, and a placement mechanism for conveniently storing maintenance supplies is arranged on the fence. The patent with the application number 2023106824146 discloses a power maintenance device, including a scissor lift connected to the base, the top of the scissor lift is connected to a maintenance platform, a first support component and a second support component are arranged on the base, the second support component is arranged vertically, and the movable end is connected to the platform base of the maintenance platform. When the maintenance platform rises vertically driven by the scissor lift, the second support component extends following the upward movement.

[0005] The above-mentioned disclosed technical solutions and some devices on the market can all provide a suitable workbench for power maintenance operations. However, their drawbacks are also relatively obvious. Due to their structural control and lift table characteristics, they are suitable for the environment where they are moved to the lower part of the area to be processed and then lifted to provide a workbench. For some environments that require working from the side or side above, they cannot be well adapted. In addition, due to the limitation of the scissor structure, the general working height is limited, and it is relatively troublesome to expand the height. Moreover, in various devices, when working at height, if the gravity on one side deviates, causing the imbalance of the workbench, it is also a problem that needs to be solved. Summary of the Invention

[0013] In some embodiments, a safety rope connecting sliding cylinder is slidably arranged on the handrail rod; The safety rope connecting sliding cylinder is in the form of a C-shaped open sleeve that fits the outer diameter of the handrail rod and avoids the connection position of the handrail rod and the L-shaped connecting rod; The C-shaped opening size of the safety rope connecting sliding cylinder is larger than the outer diameter of the handrail rod; When the safety rope connecting sliding cylinder moves upward, it quickly passes through the connection position between the handrail rod and the L-shaped connecting rod; when moving downward, it is not easy to pass through the connection position between the handrail rod and the L-shaped connecting rod. The upper end of the safety rope connecting sliding cylinder is set as: an inclined plane that fits the C-shaped opening.

[0014] In some embodiments, the side blocking member further has: a fourth form that rotates inward to form a protective cage.

[0015] In some embodiments, an adjustable counterweight assembly is provided below the top platform plate; The counterweight assembly includes: a clamping plate, a counterweight block, and a counterweight driving mechanism; The two ends of the counterweight block are respectively provided with a front guide wheel and a rear guide wheel; a horizontal sliding groove is provided on the clamping plate to cooperate with the front guide wheel, and an opening sliding groove is provided to cooperate with the rear guide wheel; When the front guide wheel reaches the front end of the horizontal sliding groove, the rear guide wheel enters the downward opening section of the opening sliding groove; the counterweight block swings downward with the front guide wheel as the center to adjust the center of gravity.

[0048] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0049] Refer to Figure 1-25, A power maintenance device, including a scissor lift base vehicle 1, which provides basic mobile support and a lifting tabletop through the scissor lift base vehicle 1. On the top plate 11 of the scissor lift base vehicle 1, a working platform 2 is assembled to move along its length direction; thus, a working environment extending to the side can be obtained, which can be better adapted to some environments with limited ground conditions; for example, when the base of some equipment is large or the ground environment does not support getting closer, the scissor lift base vehicle 1 cannot get very close, resulting in the inability to approach the basic working surface to meet the requirements; at this time, the working platform 2 of the present application extends to the side, and an enhanced working surface can be obtained.

[0050] In some embodiments, a ladder 3 is detachably assembled with a railing on the long side surface of the working platform 2.

[0051] Among them, one ladder 3 can be mounted on the working platform 2, or ladders 3 can be mounted on both sides.

[0052] It should be noted that the ladder 3 is set to cooperate with the scissor lift base vehicle 1 to obtain a further extended adaptation environment; for example, in some environments where it is difficult to get close even when the working platform 2 is shifted to the side, with the cooperation of the working platform 2 and the ladder 3, the working requirements can be met.

[0053] Correspondingly, a terminal cylinder seat 4 for inserting the bottom end of the ladder 3 is swingably arranged on the bottom surface of the working platform 2.

[0054] It should be noted that in the daily state, the ladder 3 is mounted on the long side surface of the working platform 2; when it is needed, it is assembled with the terminal cylinder seat 4.

[0055] It can be understood that two sets of terminal cylinder seats 4 can be arranged on the working platform 2 to cooperate with the installation of the ladder 3 on both sides. As Figure 18 shown, a set of ladder 3 is installed on each side to obtain a further expanded working auxiliary surface.

[0056] As Figure 3 , 9 ~11 shown; the terminal cylinder seat 4 is: a cylindrical structure matching the bottom end of the ladder 3; a groove is opened on the working platform 2, and rotating shafts are arranged at both ends of the terminal cylinder seat 4, and it is swingably assembled in the groove of the working platform 2; when not in use daily, the terminal cylinder seat 4 is hidden in the groove (such as Figure 9 the right - hand set of terminal cylinder seats 4); when it is needed, it is swung out and the ladder 3 is inserted; in addition, corresponding holes are opened on the terminal cylinder seat 4 and the ladder 3 for inserting connecting pieces such as pin shafts and bolts to enhance safety.

[0057] In addition, in order to further enhance the stability of the placement of the ladder 3, a side clamping seat 41 is rotatably assembled on the short side of the working platform 2; as Figure 11As shown, the side card seat 41 is rotatably arranged and has an opening structure for clamping the ladder 3; during use, the two side card seats 41 strengthen the limit on the ladder 3.

[0058] Preferably, short railings 21 are fixedly arranged on the short sides of the workbench 2; the sleeve part of the side card seat 41 is sleeved on the handrail of the short railing 21, and a pressing screw is threadedly assembled on the sleeve part and can be screwed inward to limit the rotation of the side card seat 41.

[0059] Furthermore, a pressing screw is rotated on the outer side of the opening structure of the side card seat 41 and can be screwed inward to tightly press the ladder 3 and lock the relative positions of the two.

[0060] It should be supplemented that: generally, the ladder 3 is limited by the cooperation of the end cylinder seat 4 and the side card seat 41, and this is in a fixed inclined form; in some special environments, the ladder 3 can also be limited only by the side card seat 41.

[0061] For example, when the distance is larger and the fixed-angle ladder form is difficult to meet the requirements; the ladder 3 is disengaged from the end cylinder seat 4 and only clamped into the side card seat 41; at the same time, the front end of the ladder 3 is found for a suitable placement position; after the preliminary placement, the relative state of the side card seat 41 and the ladder 3 is locked; the ladder 3 forms a working auxiliary surface.

[0062] Furthermore, an adjustable-length traction structure (such as a coiled rope, chain, small winch device, manual hoist, etc.) is arranged on the workbench 2; the traction structure is connected to the tail end of the ladder 3; in cooperation with the connection position of the side card seat 41, the ladder 3 is limited.

[0063] At this time, there is no need to find the placement position of the front end of the ladder; it is more convenient to use and adjust the ladder 3.

[0064] It should be noted that at this time, the center of gravity of the ladder 3 needs to be controlled outside the connection position of the side card seat 41; in the natural state, the top end of the ladder 3 always swings downward.

[0065] In some embodiments, short railings 21 are fixedly assembled above the workbench 2, and long railings 22 are vertically slidably assembled; the long railings 22 are used to better cooperate with the ladder 3.

[0066] The long railing 22 has: A first form of lowering downward to cooperate with the ladder 3; And a second form of raising upward and being assembled and connected to the short railing 21.

[0067] Such as Figure 1 As shown; in the first form, the ladder 3 is clamped above the long railing 22, and its end is assembled and connected to the short railing 21; at this time, the ladder 3 cooperates with the long railing 22 to serve as a fence structure.

[0068] like Figure 9 As shown; the long rail 22 is pulled up and assembled with the short rail 21 to serve as a fence structure alone.

[0069] Preferably, the long railing 22 consists of a top rod 221 and a plurality of vertical rods 222 .

[0070] At the same time, a hole is opened on the workbench 2 corresponding to the vertical rod 222, and the vertical rod 222 penetrates the workbench 2 downward.

[0071] It should be noted that the downward penetration position of the vertical rod 222 should be located on the outside of the top plate 11; that is, the width of the workbench 2 should be greater than the width of the top plate 11; the downward penetration state of the vertical rod 222 does not affect the relative movement of the workbench 2 and the top plate 11.

[0072] Furthermore, a plurality of sockets 223 cooperating with the ladder 3 are provided on the top rod 221 .

[0073] like Figure 6 As shown, the holder 223 is an arc-shaped structure with an open top, and the ladder 3 is inserted into the holder.

[0074] In the first form, the top rod 221 of the long railing 22 is close to the workbench; optionally, in order to control the falling height, a limit ring or other structure is fixedly welded on the vertical rod 222 to contact with the workbench, so as to control the falling height of the long railing 22 and prevent the long railing 22 from being close to the workbench.

[0075] In some embodiments, holes are formed at the ends of the short railing 21, the long railing 22, and the ladder 3; at the same time, a clamp 23 is swingably mounted at the end of the short railing 21; after the other end of the clamp 23 corresponds to the end hole of the long railing 22 or the ladder 3, a plug-in connector is inserted for assembly and connection.

[0076] like Figure 2 As shown, the upper and lower plates of the clamping plate 23 are clamped on the short railing 21, and are swung and assembled with the short railing 21 through structures such as screws and fixed shafts; at the same time, a hole is opened at the other end of the clamping plate 23; when it is swung to match the end hole of the ladder 3, connecting parts such as pins and bolts are inserted for assembly.

[0077] like Figure 9 As shown, after the clamping plate 23 corresponds to the long railing 22, the connecting parts are inserted and assembled.

[0078] In some embodiments, a central guardrail 31 is provided through the middle of the ladder 3 .

[0079] It should be noted that the width of the ladder 3 needs to be greater than the normal human body width; moreover, since this application takes into account the changes in the inclined shape, no pedal structure is provided in cooperation; the ladder 3 is composed of a long side rod and a footrest rod; in this state, the safety factor of the ladder 3 is relatively low; once a person steps on empty, danger may occur; thus, a central guard rod 31 is designed to be added.

[0080] Through the setting of the central guard rod 31, the footrest surface of the ladder 3 is divided into two sides; in this state, even if an operator steps on empty, the person will be blocked by the central guard rod 31 and there will be no risk of falling; the overall safety performance is better; moreover, due to the addition of a central guard rod 31 in the middle, the structural strength, anti-deformation ability, and load-bearing performance of the ladder 3 have all been improved.

[0081] In some embodiments, a side guard 5 is swingably arranged on the side of the ladder 3; Thus, it can not only serve as the handrail part of the ladder 3, but also has other functional forms.

[0082] Specifically, the side guard 5 has: a first form of rotating and storing inward, a second form of swinging to form a vertical side guard, and a third form of swinging to form a raised railing.

[0083] Such as Figure 3 、 4 、5 shown; when the side guard 5 is stored in the first form, it has a smaller occupied space.

[0084] Such as Figure 1 、 9 、10 shown; in the second form, the side guard 5 forms the side fence of the ladder 3; at the same time, when the ladder 3 is used as the railing of the workbench 2, the outward-extending side guard has a better fence protection effect.

[0085] Such as Figure 7 、 8 shown; when the ladder 3 is used as the railing of the workbench 2, the side guard 5 is swung to the vertical form to form a raised fence, and the protection effect is better.

[0086] In some embodiments, the side guard 5 is composed of: a plurality of sleeves 51 rotatably assembled with the ladder 3, a handrail rod 52, and several L-shaped connecting rods 53 connecting the sleeves 51 and the handrail rod 52.

[0087] Through the sleeve 51 structure, the side guard 5 can swing; the appropriately spaced L-shaped connecting rods 53 ensure the effectiveness of the side guard; the handrail rod 52 provides a grip for people.

[0088] In addition, the sleeve 51 and the ladder 3 are correspondingly provided with a limit locking member.

[0089] The limit locking parts do not need to be complicated to set up, the main requirements are reliability and easy operation.

[0090] Preferably, the limit locking member is a push bolt; holes are opened at positions corresponding to various forms of the sleeve 51 and the ladder 3; the push bolt is threadedly matched with the opening of the sleeve 51; after adjustment into place, the push bolt is screwed inwardly into the opening of the ladder 3; and the relative relationship between the two is locked.

[0091] Among them, at least one jack bolt is set at each end; the middle position can be set with a reasonable number according to the length of the ladder 3 to ensure that the limit locking of the sleeve 51 and the ladder 3 is effective and reliable.

[0092] In some embodiments, a safety rope connecting slide cylinder 6 is slidably provided on the handrail rod 52 .

[0093] It can be understood that a safety rope hanging ring is fixedly provided on the outside of the safety rope connecting slide cylinder 6 .

[0094] like Figure 16 , 17 As shown; the safety rope connecting slide 6 slides on the handrail 52; the operator's safety buckle is connected to the safety rope connecting slide 6; when the personnel moves on the ladder 3, they drag the safety rope connecting slide 6 to move; providing a safety connection point for anti-falling.

[0095] like Figure 12 , 13 As shown; the safety rope connecting slide cylinder 6 is: matched with the outer diameter of the handrail rod 52, and avoids the connection position of the handrail rod 52 and the L-shaped connecting rod 53 in the form of a C-shaped open sleeve.

[0096] The C-shaped opening size of the safety rope connecting slide cylinder 6 is larger than the outer diameter of the handrail rod 52 .

[0097] Furthermore, when the safety rope connecting slide cylinder 6 moves upward, it quickly passes through the connection position between the handrail rod 52 and the L-shaped connecting rod 53; when it moves downward, it is not easy to pass through the connection position between the handrail rod 52 and the L-shaped connecting rod 53.

[0098] In order to achieve the above effect, the upper end of the safety rope connecting slide 6 is configured as: a beveled surface 61 that matches the C-shaped opening.

[0099] Thus, when a person moves upward, the safety rope connecting slide 6 is swung to a connection position where it can quickly pass through the handrail rod 52 and the L-shaped connecting rod 53 through the cooperation of the beveled surface 61; when moving downward, due to the smaller C-shaped opening, it is not suitable to pass through the connection position between the handrail rod 52 and the L-shaped connecting rod 53, thereby avoiding the safety rope connecting slide 6 from sliding down in dangerous situations such as falling, which is safer and more reliable.

[0100] Preferably, the C-shaped opening of the safety rope connecting sliding cylinder 6 and the safety rope hanging ring are located on two symmetrical sides of the safety rope connecting sliding cylinder 6; in the normal state, the safety rope connecting sliding cylinder 6 is driven by the safety rope and is in a skewed state, and the C-shaped opening is misaligned with the handrail rod 52.

[0101] In some embodiments, a hanging ring structure is fixedly arranged at a position near the top end of the ladder 3.

[0102] During operation, the safety rope can be fixed on the hanging ring structure fixed at the top end, which is more stable.

[0103] In some embodiments, the side baffle 5 further has: a fourth form of rotating inward to form a protective cage.

[0104] It should be noted that when forming the fourth form of the protective cage, the handrail rods 52 of the two side baffles 5 approach each other; according to the length of the L-shaped connecting rod 53 (the height of the side baffle 5), control the handrail rods 52 to lock after contacting each other, or leave a gap.

[0105] Such as Figure 15 、 16 shown; due to the limited height of the side baffle 5, if the handrail rods 52 contact each other, it will result in a smaller internal space and it is difficult for personnel to pass through; thus, a certain gap is left (if the height of the handrail rods 52 is designed larger, they can contact each other).

[0106] Furthermore, a rope or a connecting rod is connected between the two side baffles 5 to enclose the gap between the two, forming a more reliable and safe protective cage form.

[0107] Such as Figure 15 shown; the ladder 3, the side baffle 5 and the rope or the connecting rod cooperate to form a fully enclosed protective structure.

[0108] Preferably, when using a rope, one end is fixedly connected and the other end is detachably connected, such as tying a knot on-site, etc.; when using a connecting rod, corresponding connecting pieces are provided, such as the connecting rod passing through the side baffle 5 and installing bolts for fixing, etc.

[0109] In some embodiments, a guiding slide rail 7 in a clamping form is cooperatively arranged between the top platform plate 11 and the operation table 2; to ensure the relative sliding of the two.

[0110] Preferably, a guiding slide rail 7 with a T-shaped fit is adopted.

[0111] In some embodiments, a long rack is fixedly arranged at the lower end of the operation table 2, and multiple groups of gears are arranged above the top platform plate 11 in cooperation with the long rack; one or more of the gears are connected to a power motor; through the meshing drive of the gears and the long rack, the relative positions of the operation table 2 and the top platform plate 11 are adjusted.

[0112] In some embodiments, an adjustable counterweight assembly 8 is provided below the top table board 11; to perform adaptive adjustment when the load of the workbench 2 is unbalanced.

[0113] Specifically, the counterweight assembly 8 includes: a clamping plate 81, a counterweight block 82, and a counterweight driving mechanism 83.

[0114] Among them, two clamping plates 81 cooperate with one counterweight block 82; front guide wheels 84 and rear guide wheels 85 are respectively arranged at both ends of the counterweight block 82; a horizontal chute 811 is arranged on the clamping plate 81 to cooperate with the front guide wheel 84, and an open chute 812 is arranged to cooperate with the rear guide wheel 85.

[0115] As Figure 22 、 24 、shown in 25; in the centered state, the front guide wheel 84 and the rear guide wheel 85 are respectively located in the horizontal parts of the horizontal chute 811 and the open chute 812; the counterweight block 82 is in a centered and flat state.

[0116] As Figure 23 shown; when the front guide wheel 84 reaches the front end of the horizontal chute 811, the rear guide wheel 85 enters the downward opening section of the open chute 812; by the force applied by the counterweight driving mechanism 83, the counterweight block 82 swings downward with the front guide wheel 84 as the center to adjust the center of gravity.

[0117] Preferably, the counterweight driving mechanism 83 includes: a power lead screw 831, a lower base 832 driven by the power lead screw 831, and a telescopic rod 833 with one end hinged to the lower base 832 and the other end hinged to the tail end of the counterweight block 82; among them, the telescopic rod 833 is in an electric or hydraulic form.

[0118] It should be noted that the counterweight assembly 8 needs to cooperate with the lifting change of the scissor lift base vehicle 1; during the lifting process, when the position of the counterweight block 82 does not need to be adjusted, the telescopic rod 833 is adjusted to a passive state; as the scissor lift base vehicle 1 lifts and lowers, the telescopic rod 833 is stretched or compressed, and cooperates with the active movement of the lower base 832 to keep the position of the counterweight block 82 unchanged.
