[0037] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work also belong to the protection scope of the present application.

[0038] The terms "first", "second", "third", and "fourth" and the like in the description and in the claims of the present application and the accompanying drawings are used for distinguishing between similar objects talking about the same object and are not necessarily used to describe a particular sequential order. Also, the terms "comprises", "comprising", "includes", "including", or the like means encompassing, and specifically, does not exclude the presence of additional elements or steps. A process, method, system, product, or apparatus that comprises a list of steps or modules does not necessarily require the order of the steps or modules to be followed according to the listing.

[0039] Reference herein to "an embodiment" means that a particular feature, structure, result, or characteristic described in connection with an embodiment can be included in at least one embodiment of the application. The appearances of the phrase that an embodiment in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of other embodiments. It is expressly understood that the embodiments described herein are combinable with each other.

[0040] The ring-shaped concrete pole is a power facility made of concrete and steel bars, mainly used for supporting and erecting power transmission lines. In daily operation and maintenance work, power workers need to climb the pole from the bottom to the top to maintain and repair the power transmission lines and insulation components.

[0041] Since this type of pole is columnar and smooth in surface, a climbing pole device with a carabiner is generally used to help workers climb the pole. This climbing method requires workers to have strong lower limb strength and body coordination, and the climbing process consumes a lot of physical energy, which is not conducive to workers' maintenance and repair work at the top of the pole. On the other hand, pole breaking accidents occur from time to time, and since the safety belt of the pole climber can only be connected to the pole, pole breaking often causes the worker to lose the protection of the safety belt and fall from a high place, posing a threat to the safety of the worker.

[0042] In recent years, with the improvement of working conditions, some work sites have also equipped aerial work platforms to lift workers to a high place for power line maintenance and repair, but require the work site to have space for aerial work platform deployment, which greatly increases the operation cost and lacks competitiveness in economy, and cannot effectively deal with the risk of pole falling.

[0043] Therefore, the embodiments of the present application provide a lifting device. The related content, concepts, technical problems, technical solutions, and beneficial effects of the embodiments of the present application are described below.

[0044] Reference is made to Figure 1 , Figure 1is a schematic diagram of an application scenario of a lifting device provided by an embodiment of the present application. The support structure changes from a first working state to a second working state as shown in the figure. The first working state is a working state corresponding to a first length, and the second working state is a working state corresponding to a second length. When the support structure changes from the first length to the second length, the target object is lifted to a required height for maintenance work, so as to maintain the target pole. The first working state is usually a retracted or folded state, at which time the work platform is at a lower height, facilitating the lifting device to be set on the target pole or the initial position to be adjusted. The second working state is usually an unfolded or elongated state, at which time the work platform is raised to a height suitable for the maintenance part of the target pole. The target object can perform maintenance operations on the work platform.

[0045] Referring to Figure 2 , Figure 2 is a plan view of a lifting device based on four components provided by an embodiment of the present application. The lifting device provided by an embodiment of the present application is used to lift a target object, so that the target object performs maintenance work on a target pole 1. The lifting device includes n lifting components. n is greater than or equal to 3, so as to ensure the stability of the lifting device around the target pole and the overall support reliability. The target object can include maintenance personnel, maintenance tools, etc.

[0046] Specifically, each lifting component includes a roller 8, a power device, a surrounding structure 4, a support structure 3, a stabilizing structure 2, and a work platform 5. The work platform is used to carry the target object. The power device acts on the support structure, so that the support structure changes from a first length to a second length. The first length is less than the second length. The stabilizing structure is used to fix the other end of the support structure. When the support structure changes from the first length to the second length, the surrounding structure is driven to rise along the direction of the target pole through the connection relationship between one end of the support structure and the surrounding structure, the fixing effect of the stabilizing structure on the other end of the support structure, and the rolling connection between the roller and the target pole. The work platform changes from a first height to a second height along the direction of the target pole. The first height is less than the second height. The lifting device is used to lift the target object from the first height to the second height, so that the target object performs maintenance work on the target pole.

[0047] The surrounding structure refers to a component used to fit the outer wall of the target pole, so as to realize the surrounding positioning of the lifting device on the target pole. The stabilizing structure refers to a component used to carry the overall weight of the lifting device and maintain the stability of the lifting device during work.

[0048] Further, for each lifting component, the rollers are arranged on the inner side wall of the embracing structure; the work platform is arranged on the outer side wall of the embracing structure; the outer side wall of the embracing structure is further connected with one end of the support structure; the other end of the support structure is connected with the stabilizing structure; the n embracing structures of the n lifting components enclose a first space, and the target pole is located in the first space, and the rollers are in rolling connection with the target pole.

[0049] The first space refers to a closed or semi-closed space formed by the n embracing structures of the n lifting components after splicing, which is used to accommodate the target pole. The target pole is located in the first space, and the rollers on the inner side wall of the embracing structure are in rolling connection with the outer wall of the target pole, which not only ensures that the lifting device can be stably positioned on the target pole, but also enables the lifting device to adjust the position along the height direction of the pole or adjust the orientation of the work platform along the circumferential direction of the pole according to the maintenance requirements, thereby improving the flexibility of maintenance.

[0050] For each lifting component, the rollers are arranged on the inner side wall of the embracing structure, which forms rolling contact between the embracing structure and the outer wall of the target pole, thereby reducing the frictional resistance when the lifting device moves along the axial direction of the pole or adjusts the circumferential direction. The work platform is arranged on the outer side wall of the embracing structure as a load carrier for the target object. The outer side wall of the embracing structure is further fixed or detachably connected with one end of the support structure, and the other end of the support structure is fixed or detachably connected with the stabilizing structure, thereby forming a longitudinal support chain to provide vertical support force for the work platform.

[0051] Optionally, the first connecting structure is arranged between adjacent embracing structures of the n embracing structures; and each group of adjacent embracing structures is connected through the first connecting structure. The first connecting structure connects the adjacent embracing structures of the lifting components, so that the n embracing structures form a complete annular whole, thereby avoiding the device deviation caused by the poor fit of a single embracing structure with the pole.

[0052] The first connecting structure refers to a component for connecting the adjacent embracing structures of the lifting components into a whole.

[0053] Optionally, the embracing structure is an n-th hollow cylindrical body.

[0054] Optionally, when n is 3, the embracing structure corresponds to an arc of 120 degrees; and when n is 4, the embracing structure corresponds to an arc of 90 degrees. This design can ensure that the n components form an annular structure that is adapted to the shape of the cylindrical target pole after splicing, thereby maximizing the fit area of the embracing structure with the pole and further optimizing the stability of the lifting device.

[0055] Optionally, the second connecting structure is arranged between adjacent stable structures of the n stable structures of the n lifting components; and each group of adjacent stable structures is connected through the second connecting structure. The stable structures of adjacent lifting components are connected through the second connecting structure, and the n stable structures can form a complete annular support base, thereby enhancing the bearing capacity and anti-toppling performance of the bottom of the device, and the device is particularly suitable for maintenance operations in complex environments such as outdoor wind load.

[0056] The second connecting structure refers to a component for connecting the stable structures of adjacent lifting components into a whole.

[0057] Optionally, the stable structure is an n-th part of a hollow cylinder.

[0058] Optionally, when n is 3, the stable structure corresponds to an arc of 120 degrees; and when n is 4, the stable structure corresponds to an arc of 90 degrees. This design can ensure the stability of the lifting device through the ground support area of the stable structure after the n components are spliced.

[0059] Optionally, one end of the support structure is provided with a first hinge 7, and the other end of the support structure is provided with a second hinge 6; the support structure is connected to the outer side wall of the embracing structure through the first hinge; and the support structure is connected to the stable structure through the second hinge.

[0060] The first hinge refers to a component for realizing the rotatable connection between the support structure and the embracing structure; and the second hinge refers to a component for realizing the rotatable connection between the support structure and the stable structure. The provision of the hinges provides the support structure with the freedom of rotation around the connection points, and enables the support structure to realize the state conversion.

[0061] Optionally, the power equipment can be a hydraulic mechanism. The hydraulic mechanism, also known as an oil press, is an industrial machine that uses liquid as a working medium and realizes energy transmission based on Pascal's law. The hydraulic mechanism is composed of a main machine, a power system, and a hydraulic control system, and the driving mode is divided into two types: pump direct driving and pump-accumulator driving. The support structure of each component can be controlled by the hydraulic mechanism, and the length change can be adjusted in coordination to ensure that the working platform of the lifting device can be smoothly lifted.

[0062] When the power equipment acts on the support structure, the support structure can be driven to rotate around the first hinge and the second hinge, and the length of the support structure can be increased, so that the support structure is converted from the first length to the second length. During the state conversion process, the rolling cooperation between the rollers and the electric poles can assist in adjusting the overall position of the device, and ensure that the working platform is accurately lifted to the maintenance area.

[0063] In the embodiment, the lifting device forms a first space suitable for the target electric pole through the splicing of the embracing structures of the n lifting components, and realizes low friction with the electric pole in combination with the rollers, so as to facilitate the positioning and position adjustment of the device.

[0064] In the embodiments of the present application, the rotating freedom of the support structure is provided through the hinge connection, and the height adjustment of the work platform is realized in combination with the power equipment, so as to meet the requirements of different maintenance positions.

[0065] In the embodiments of the present application, the first and second connecting structures are used to respectively enhance the integrity of the embracing structure and the stability structure, and the shape design of the n-th hollow cylinder is used to improve the fitting degree and the overall stability of the device to the electric pole, so that the overall structure is reliable and flexible to operate, and can effectively support the target object to complete the maintenance work on the target electric pole, thereby reducing the difficulty and safety risk of maintenance.

[0066] In specific embodiments, referring to Figure 3 and Figure 4 , Figure 3 is a top view of a lifting device based on four components provided by the embodiments of the present application; Figure 4 is a top view of a lifting device based on three components provided by the embodiments of the present application. As shown in Figure 3 , when n is 4, the corresponding arc of the stability structure 2 and the embracing structure 4 is 90 degrees. As shown in Figure 4 , when n is 3, the corresponding arc of the stability structure 2 and the embracing structure 4 is 120 degrees.

[0067] The embodiments of the present application also provide an electrical equipment including the lifting device described above in part or in whole.

[0068] Referring to Figure 5 , Figure 5 is a flowchart of a lifting method provided by the embodiments of the present application. As shown in Figure 5 , the embodiments of the present application also provide a lifting method, which is applied to the lifting device described above in part or in whole. The method includes but is not limited to the following steps:

[0069] Step S101: obtaining structure data of a target electric pole;

[0070] The structure data includes the type of the electric pole, the diameter of the electric pole, and the height of the electric pole.

[0071] Step S102: obtaining work data;

[0072] The work data includes the work height, the work weight, and the work terrain.

[0073] Step S103: determining the first position of the stability structure according to the work terrain;

[0074] Step S104: determining the embracing parameters of the embracing structure according to the type of the electric pole, the diameter of the electric pole, the height of the electric pole, and the work height;

[0075] The embracing parameter is used to reflect the size of the embracing structure.

[0076] Step S105: determining the power parameter of the power equipment according to the first position, the working height and the working weight.

[0077] The power parameter includes power.

[0078] Step S106: changing the support structure from the first length to the second length according to the first position, the embracing parameter and the power parameter, to complete the lifting operation.

[0079] Specifically, the structure data refers to a parameter set characterizing the physical characteristics of the target pole, used to adapt the embracing structure of the lifting device; the working data refers to a parameter set characterizing the requirements of the maintenance work and the environmental conditions, used to determine the support and power of the lifting device; the embracing parameter refers to a size parameter of the fitting adaptability of the embracing structure and the target pole, such as the inner diameter, the axial length, the splicing gap, etc.; the power parameter refers to an output characteristic parameter of the power equipment that can smoothly drive the state conversion of the support structure; and the first position refers to the fixed placement position of the stable structure on the work terrain.

[0080] In a possible embodiment, the structure data of the target pole is obtained by field measurement or archive retrieval to obtain the pole type, the pole diameter and the pole height. The pole type includes equal-diameter poles, tapered poles, concrete poles, steel poles, composite material poles, etc.; the pole diameter needs to measure the cross-sectional diameter at the position corresponding to the working height, which can be measured by a laser caliper or a ring gauge at three points along the circumference of the pole to take the average value to ensure data accuracy; and the pole height is the total length from the ground fixed end to the top end of the pole, which can be measured vertically from the ground to the top insulator installation position by a laser range finder.

[0081] In a possible embodiment, the working data is obtained. The working height is the radial height of the target object to be reached, which can be determined according to the maintenance task, and the vertical distance from the maintenance site to the ground is located by a laser range finder; the working weight is the total mass of the target object, including the weight of the maintenance personnel and the weight of the tools and equipment, which can be weighed by a portable weighing instrument and then summed up, wherein 10%-15% of the weight margin is reserved to cope with dynamic load, such as the center of gravity shift caused by personnel movement; and the work terrain is the ground condition of the placement area of the lifting device, which is determined by field survey to determine the terrain type, such as flat hard ground, gentle slope ground, muddy ground and gravel ground, and the ground slope is measured by a slope meter and the bearing capacity is determined by a drop hammer type bearing capacity instrument.

[0082] In a possible embodiment, the first position of the stabilizing structure is determined according to the work terrain, and the force balance and settlement risk of the stabilizing structure are ensured in combination with the terrain characteristics. If it is a flat hard ground, for example, when the slope is ≤ 3° and the bearing capacity is ≥ 150 kPa, the first position can be selected as a symmetrically distributed area around the target pole axis, for example, when n = 3, the three stabilizing structures are distributed at an angle of 120°.

[0083] In a possible embodiment, the embracing parameters of the embracing structure are determined according to the pole type, the pole diameter, the pole height, and the work height, and the embracing parameters are the inner diameter and the axial length. The inner diameter needs to be adapted to the pole diameter at the work height, and the axial length is determined according to the pole height and the work height and needs to cover a range of 0.3-0.5 m above and below the work height, for example, when the work height is 3 m, the axial length is set to 0.8 m, covering a range of 2.6-3.4 m, so as to ensure that the support range of the embracing structure on the pole is sufficient and the work platform is prevented from shaking.

[0084] In a possible embodiment, the power parameters of the power equipment are determined according to the first position, the work height, and the work weight, and the determination of the power parameters needs to be based on the coupled calculation of the load and the motion demand.

[0085] Firstly, the work weight is the total load, which includes the work platform weight G1, the target object weight G2, and the self-weight G3 of the support structure, that is, the total load G4 = G1 + G2 + G3, and according to the dynamic load coefficient K1, the actual load G5 = G × K1.

[0086] Then, the elongation of the support structure is determined according to the work height H, and in combination with the motion trajectory of the support structure, which can be a circular arc path rotating around the hinge, the lifting distance S = H / sinθ of the support structure can be calculated, and θ is the included angle between the support structure and the horizontal plane, which is determined according to the horizontal distance between the first position and the pole.

[0087] Therefore, the output power P1 of the power equipment needs to meet: P1 ≥ (G5 × v) / η, wherein v is the rated lifting speed of the support structure, which can be 0.1-0.3 m / s to ensure stability, and η is the mechanical efficiency of the lifting device, which includes the friction loss of the hinge and the transmission mechanism.

[0088] In addition, if the first position is on a terrain with a slope ≥ 10°, the slope compensation coefficient K2 needs to be additionally calculated, and the calculation method of K2 can be: K2 = 1 + 0.05 × slope value, that is, the final power P2 = P1 × K2, so as to avoid insufficient power caused by the terrain and ensure that the support structure can complete the state conversion at a uniform speed.

[0089] In a possible embodiment, the support structure is changed from the first length to the second length according to the first position, the embracing parameter and the power parameter, first, the embracing structure of each lifting component is adjusted according to the embracing parameter, and the embracing structure is sleeved outside the target electric pole; then the power equipment is started, and the driving force is output according to the determined power parameter, to drive the support structure to rotate synchronously around the first hinge and the second hinge, the support structure is in a folded state in the first length, the power equipment drives the support structure to elongate through the hydraulic push rod or the electric screw rod, to drive the embracing structure to ascend along the electric pole in the axial direction, and meanwhile the embracing structure is closely attached to the outer wall of the electric pole under the action of gravity; when the height sensor of the operation platform detects that it reaches the set operation height, the power equipment is automatically switched to the pressure maintaining mode, and the support structure remains in the elongated state, at this time, the operation platform is in a horizontal stable state, and the target object can enter the operation platform to perform the maintenance operation, and the lifting operation is completed.

[0090] In the embodiment of the application, the embracing parameter, the power parameter and the stable structure position are determined based on the structure data and the operation data, so as to avoid problems such as poor adaptability of the device, lifting jam and the like caused by blind operation. Moreover, through calculation of the power parameter, the dynamic load and the slope compensation coefficient are determined, to ensure that the lifting process is stable and safe. The lifting method of the embodiment of the application takes into account different electric pole types, operation heights and terrains, and has strong universality, effectively reduces the operation difficulty of the maintenance operation, and improves the safety reliability and operation accuracy of the lifting device.

[0091] In summary, the application can realize controllable lifting of the attached operation platform through the embracing type hydraulic control hinge structure combination, and provides a labor-saving pole climbing means for the operation personnel, and reduces the requirement for physical quality of the operation personnel.

[0092] The application adopts a combined design, has small occupied area when in use, is more convenient to transport and carry, is suitable for operation areas that cannot be reached by the aerial work vehicle, reduces operation cost, and improves operation convenience.

[0093] The application adopts the embracing electric pole design, and the shear resistance of the electric pole is assisted to improve, and the risk of pole falling is reduced.
