Description

Technical Field

[0001] The present application relates to the field of electric power construction equipment, and in particular to a lifting device used in electric power construction. Background Art

[0002] Lifting equipment in power construction refers to mechanical equipment used to lift personnel, equipment and materials to high-altitude working positions during power projects, especially during the construction and maintenance of power transmission lines. Power construction lifting equipment can quickly lift personnel and materials to high-altitude working positions, reduce the need for manual scaffolding, reduce labor costs, shorten construction time and construction costs, and improve project progress.

[0003] At present, the lifting equipment for power construction mainly includes a mobile trolley, a main structure frame, a lifting platform for carrying personnel and equipment, a lifting drive device (such as a scissor-type lifting mechanism and a driving hydraulic cylinder) for driving the lifting platform up and down, a control system for controlling the lifting of the equipment, hydraulic support legs, anti-fall safety devices, and lighting, communication equipment, tool racks, etc. equipped according to specific work needs. When a power transmission line fails, the hydraulic cylinder drives the scissor-type lifting mechanism to drive the lifting platform, personnel and equipment to the specified height, and then the hydraulic support legs are deployed to ensure the stability of the equipment. Then the construction personnel wear double hook safety The belt is fixed to the platform guardrail through the slide rail hook, and an insulation resistance tester is used to confirm that the power is off in the working area, and ground wires are hung on both sides of the wire, and then the wires or electrical components are repaired; however, the existing power construction lifting equipment is mainly suitable for flat hard ground. For inclined or steep slopes in mountainous areas, the ground is mostly soft soil, and large mobile equipment is difficult to intervene. Especially for inclined soft soil slopes, the lifting platform of the equipment is difficult to reach the construction site by vertical lifting, and it cannot stably support the slope with a large slope, making construction difficult, time-consuming and labor-intensive, resulting in the inability to carry out construction work smoothly. Summary of the invention

[0004] In order to facilitate construction workers to carry out maintenance work on power equipment in soft soil sections such as inclined or steep slopes and to improve the stability and applicability of the equipment, the present application provides a lifting device for power construction.

[0005] The present application provides a lifting device for electric power construction, which adopts the following technical solution: A lifting device for electric power construction, comprising: A mobile carrier, wherein a frame, a lifting drive device disposed on the frame, and a lifting platform disposed on the top of the lifting drive device are fixedly disposed on the mobile carrier; and further comprising: An adjustment mechanism, disposed between the lifting platform and the frame, for extending the lateral and longitudinal dimensions of the lifting platform and adjusting the inclination angle between the lifting platform and the ground; An adaptive support mechanism is arranged on the frame and the number is set to four, and the adaptive support mechanism includes a rotating component, a primary anti-displacement component, and a secondary anti-displacement component; the rotating component is used to drive the primary anti-displacement component or the secondary anti-displacement component to rotate toward or away from the ground; the primary anti-displacement component is used to provide buffer support for the frame and prevent the mobile carrier from shifting and sinking downward; the secondary anti-displacement component is used to connect the frame to the ground; Among them, when the electric construction lifting equipment is on a flat soft ground, the rotating assembly and the first-level anti-displacement assembly are started; when the electric construction lifting equipment is on an inclined soft ground, the rotating assembly, the first-level anti-displacement assembly and the second-level anti-displacement assembly are all started.

[0006] By adopting the above technical solution, when the construction site is on a flat soft ground, the construction workers first move the mobile carrier close to the construction site, and then drive the first-level anti-displacement component to rotate to the side close to the ground through the rotating component, so that the first-level anti-displacement component is in contact with the ground. The first-level anti-displacement component improves the stability of the mobile carrier and the frame on the soft ground through buffer support, and prevents the mobile carrier from shifting and sinking significantly during the construction process. Then the construction workers board the lifting platform and wear double-hook safety belts, which are fixed to the guardrail on the lifting platform through the slide rail hook. Then the lifting drive device is started to lift the lifting platform to the specified height, and the construction workers can repair or replace the wires or electrical components. When the construction site is on an inclined soft ground, after the mobile carrier moves close to the construction site, it is necessary to start the rotating component, the first-level anti-shift component and the second-level anti-shift component in the adaptive support mechanism. The rotating component synchronously drives the first-level anti-shift component and the second-level anti-shift component to rotate toward the ground side in the opposite direction. The first-level anti-shift component improves the stability of the mobile carrier and the frame on the inclined soft ground through buffer support, and at the same time makes it difficult for the mobile carrier to shift along the inclination direction of the inclined surface and to settle significantly along the inclination direction of the vertical inclined surface during construction. The second-level anti-shift component is connected to the ground to prevent the equipment from sliding or tipping over on the inclined surface. Then the construction personnel also need to adjust the inclination angle between the lifting platform and the ground through the adjustment mechanism to keep the lifting platform horizontal. Then the construction personnel board the lifting platform and wear double-hook safety belts, which are fixed to the guardrail on the lifting platform through the slide rail hook. Then the lifting drive device is started to lift the lifting platform to the specified height, and the construction personnel can repair or replace the wires or electrical components. During the construction process, construction workers can use the adjustment mechanism to adjust the lateral and longitudinal dimensions of the lifting platform within a certain area to adapt it to construction needs without having to move the position again by moving the carrier, thereby improving the convenience and efficiency of construction; the first-level anti-displacement component in the adaptive support mechanism uses buffering support to prevent the equipment from sinking and shifting on soft ground, and the second-level anti-displacement component prevents the equipment from sliding or tipping over by connecting with the inclined ground. The first-level anti-displacement component is used in conjunction with the second-level anti-displacement component, so that the equipment can operate stably on the inclined soft ground; at the same time, through the dual protection of the adaptive support mechanism and the adjustment mechanism, the construction risk of the equipment on the inclined ground is reduced, so that the equipment can quickly locate and stably operate in complex terrains such as mountainous areas and soft soil slopes where traditional equipment is difficult to intervene, thereby improving construction efficiency and flexibility, and reducing construction time and labor costs.

[0007] Optionally, the rotating assembly includes: A rotating shaft is rotatably connected to the frame, a primary bevel gear and a worm gear are fixedly sleeved on the outer side of the rotating shaft, a secondary bevel gear is sleeved on the outer side of the rotating shaft, a worm is rotatably connected to the frame, the worm is meshed with the worm gear, and one end of the worm is connected to a driving motor; A transmission bevel gear is rotatably connected to the frame, and the transmission bevel gear is meshed with both the primary bevel gear and the secondary bevel gear; A primary rotating seat, sleeved on the outer side of the rotating shaft and fixedly connected to the primary bevel gear, and the primary anti-shifting assembly is arranged on the primary rotating seat; A secondary rotating seat is sleeved on the outer side of the rotating shaft and is rotationally connected to the secondary bevel gear, and the secondary anti-shifting component is arranged on the secondary rotating seat; A control connection component is arranged between the secondary bevel gear and the secondary rotating seat, and is used to control the connection between the secondary bevel gear and the secondary rotating seat.

[0008] By adopting the above technical solution, when the construction site is on a flat soft ground, the rotating component only needs to drive the first-level anti-displacement component to rotate toward the ground. First, the drive motor is started, and the drive motor drives the worm to rotate. The worm drives the rotating shaft to rotate through the worm gear, and the rotating shaft drives the first-level bevel gear to rotate. The first-level bevel gear drives the transmission bevel gear to rotate through meshing, and the transmission bevel gear further drives the first-level rotating seat to rotate, so that the first-level anti-displacement component rotates toward the ground and abuts the ground. After the first-level anti-displacement component abuts the ground, it prevents the equipment from shifting and sinking. When the construction site is on an inclined soft ground, the rotating assembly needs to synchronously drive the primary anti-displacement assembly and the secondary anti-displacement assembly to rotate toward the ground side in the opposite direction. First, the secondary bevel gear is connected to the secondary rotating seat by controlling the connecting component, and then the drive motor is started. The drive motor drives the worm, worm wheel, rotating shaft, primary bevel gear, transmission bevel gear, and secondary bevel gear to rotate synchronously. At this time, the primary rotating seat drives the primary anti-displacement assembly to rotate toward the ground, and the secondary rotating seat drives the secondary anti-displacement assembly to rotate toward the ground side in the opposite direction of the primary anti-displacement assembly. The rotating assembly can flexibly, quickly and accurately control the operation of the primary anti-displacement assembly and the secondary anti-displacement assembly according to the terrain conditions, so that the equipment can operate stably on both flat soft ground and inclined soft ground, simplifying the operation process.

[0009] Optionally, the control connection component includes: A connecting sleeve, rotatably connected to the frame and sleeved on the outside of the rotating shaft, the connecting sleeve is fixedly connected to the secondary rotating seat and is located between the rotating shaft and the secondary bevel gear, and the connecting sleeve is provided with a plurality of connecting holes evenly spaced along its circumference; A connecting block is slidably connected to the secondary bevel gear along the radial direction of the connecting sleeve and can be inserted into the connecting hole; The first electric telescopic rod is fixed between the connecting block and the secondary bevel gear.

[0010] By adopting the above technical solution, when controlling the connection between the secondary bevel gear and the secondary rotating seat by controlling the connecting component, first start the first electric telescopic rod, the output end of the first electric telescopic rod pushes the connecting block to slide toward the connecting sleeve along the radial direction of the connecting sleeve, and inserts the connecting block into the connecting hole, so that the secondary bevel gear can be connected to the connecting sleeve. Since the connecting sleeve is fixedly connected to the secondary rotating seat, the secondary bevel gear drives the secondary rotating seat to rotate through the connecting sleeve. When it is necessary to disconnect the connection between the secondary bevel gear and the secondary rotating seat, it is only necessary to reversely start the first electric telescopic rod again, and the first electric telescopic rod pulls the connecting block out of the connecting hole, so that the secondary bevel gear can be disconnected from the connecting sleeve, so that the secondary bevel gear can no longer drive the secondary rotating seat and the secondary anti-shift assembly to rotate; by controlling the connecting component, the construction personnel can flexibly control the rotation of the secondary anti-shift assembly according to the terrain conditions, so that the equipment can adapt to various terrains such as flat soft soil and inclined soft soil.

[0011] Optionally, a damping sleeve is fixedly provided on the outer side of the rotation connection between the connecting sleeve and the frame.

[0012] By adopting the above technical solution, the damping sleeve limits the free rotation of the connecting sleeve through friction or damping force. When the secondary bevel gear is disconnected from the connecting sleeve, the damping sleeve can prevent the connecting sleeve from rotating freely due to inertia or external force, thereby ensuring that the connecting sleeve remains stable.

[0013] Optionally, the primary anti-displacement assembly includes a support spaced apart on one side of the primary rotating seat, a plurality of damping telescopic rods fixed between the support and the primary rotating seat, and a spring sleeved on the outside of the damping telescopic rod.

[0014] By adopting the above technical scheme, when the support rotates to abut against the ground, the spring is in a compressed state and applies downward pressure to the support. The compression force of the spring presses the support against the ground, increases friction, and prevents the equipment from shifting during construction. At the same time, under the joint action of the spring and the damping telescopic rod, the equipment can be protected from strong wind shaking and shock absorption. Regardless of whether the strong wind blows upward or downward along the slope, it can buffer the support and absorb the impact force, so that the secondary anti-displacement component is not easy to be pulled out of the ground. When used in conjunction with the secondary anti-displacement component, the secondary anti-displacement component can be ensured to have a stable connection and reduce the pulling force along the vertical slope. After the secondary anti-displacement component is stably connected, it can in turn make the primary anti-displacement component not easy to slide along the slope.

[0015] Optionally, a support shell is provided along the circumferential fixed sleeve of the first-level rotating seat, and the support shell is slidably connected to the support along the length direction of the damping telescopic rod; a shrinkage block is fixedly provided on one side of the first-level rotating seat close to the support; and the bottom of the support close to the side of the frame is arranged in an arc shape.

[0016] By adopting the above technical scheme, the supporting shell is used to enhance the connection strength between the damping telescopic rod and the primary rotating seat and the support, so that the connection between the damping telescopic rod and the primary rotating seat and the support is not easy to break; the shrinkage limit block is used to prevent the damping telescopic rod and the spring from being over-pressurized, thereby increasing the service life of the damping telescopic rod and the spring; when the support rotates toward the ground, the bottom of the support close to the frame side will first contact the ground, and the bottom of the support close to the frame side is arranged in an arc shape to prevent the part of the support that first contacts the ground from being easily subjected to excessive stress during the rotation of the support, thereby reducing the lateral shear force at the connection between the damping telescopic rod and the primary rotating seat and the support.

[0017] Optionally, the secondary anti-displacement component includes: A telescopic support rod is rotatably connected to the secondary rotating seat, the telescopic support rod can be telescoped along its own length direction, and a drill bit is fixedly arranged at one end of the telescopic support rod away from the secondary rotating seat; A driven bevel gear, fixedly sleeved on the outside of the telescopic support rod; A transmission shaft is rotatably connected to the secondary rotating seat, and a driving bevel gear is provided on the outer fixed sleeve of the transmission shaft, and the driving bevel gear is meshed with the driven bevel gear; A transmission is arranged on the secondary rotating seat, the output shaft of the transmission is connected to the transmission shaft, and a rotating motor is arranged at one end of the input shaft of the transmission.

[0018] By adopting the above technical solution, when connecting with the ground through the secondary anti-displacement component, the rotating motor is started first, and the rotating motor transmits power to the transmission shaft through the transmission. The transmission shaft drives the driving bevel gear to rotate, and the driving bevel gear engages with the driven bevel gear and drives the telescopic support rod to rotate. Then the telescopic support rod drives the drill bit to drill toward the ground. During the drilling process, the telescopic support rod extends until the telescopic support rod drives the drill bit to reach a preset depth, and then it can be firmly connected to the ground to prevent the equipment from sliding or tipping over on an inclined surface.

[0019] Optionally, the telescopic support rod includes a plurality of protective shells which are sequentially mounted, and adjacent protective shells are slidably connected along their own length directions. A multi-stage hydraulic telescopic rod is arranged inside the telescopic support rod, and both ends of the multi-stage hydraulic telescopic rod are respectively rotatably connected to the protective shell away from the secondary rotating seat and the protective shell close to the secondary rotating seat.

[0020] By adopting the above technical solution, when the multi-stage hydraulic telescopic rod is started, the end of the multi-stage hydraulic telescopic rod will drive the protective shell away from the side of the secondary rotating seat to move below the ground, cooperate with the drill bit to drill into the ground and connect with the ground. At the same time, the protective shell can protect the internal multi-stage hydraulic telescopic rod from being affected by the soil, ensuring that the telescopic support rod can be extended smoothly.

[0021] Optionally, the adjustment mechanism includes: A hydraulic adjustment cylinder is hinged between the frame and the bottom of the lifting drive device, and one side of the bottom of the lifting drive device is rotatably connected to the frame; Extension plates are slidably connected to the inside of the lifting platform, and are provided in four numbers. Two opposite extension plates form a group, and the two groups of extension plates are staggered along the height direction of the lifting platform, and the moving directions of the extension plates in the two groups are perpendicular to each other; A driving shaft is rotatably connected to the lifting platform in a direction perpendicular to the lifting platform, and a power motor is provided at one end of the driving shaft; A driving gear is rotatably sleeved on the outside of the driving shaft, two of which are arranged and distributed along the length direction of the driving shaft, two groups of extension plates correspond to the two driving gears one by one, each of the extension plates is fixed with a driving rack, and the driving racks on the two extension plates in each group are meshed with the corresponding driving gears at the same time; A control drive assembly is disposed between the drive shaft and the drive gear, and is used to achieve the connection between the drive shaft and the drive gear.

[0022] By adopting the above technical solution, when the construction site is on an inclined soft ground, when adjusting the inclination angle of the lifting platform through the adjustment mechanism, the hydraulic adjustment cylinder is first started, and the hydraulic adjustment cylinder pushes the bottom of the lifting drive device to change the inclination angle between the lifting platform and the ground until the lifting platform is adjusted to a horizontal state. When adjusting the horizontal and vertical dimensions of the lifting platform through the adjustment mechanism, the control drive component is first started to realize the connection between the drive shaft and the drive gear, and then the drive shaft is driven to rotate by the power motor, and the drive shaft can drive the drive gear to rotate, and the drive gear is engaged with the drive rack on the extension plate, driving the extension plate to slide to the outside of the lifting platform, and the moving directions of the two groups of extension plates are perpendicular to each other, respectively adjusting the horizontal and vertical dimensions of the lifting platform; wherein the two groups of extension plates can be adjusted separately according to the actual needs during construction, that is, by controlling the drive component to separately control one of the drive gears to connect with the drive shaft, so as to independently and flexibly adjust the horizontal and vertical dimensions of the lifting platform to adapt to different terrain conditions.

[0023] Optionally, the control drive component includes: A plug-in block is connected to the driving gear by sliding along the radial direction of the driving shaft. The driving shaft is provided with a plurality of plug-in slots evenly spaced along its circumference, and the plug-in block can be plugged into the plug-in slots; The second electric telescopic rod is fixed between the plug-in block and the driving gear.

[0024] By adopting the above technical solution, when one of the driving gears is connected to the driving shaft by controlling the driving assembly alone, the second electric telescopic rod is first started, and the second electric telescopic rod pushes the plug-in block to slide into the plug-in slot on the driving shaft along the radial direction of the driving shaft, so that the plug-in block is inserted into the plug-in slot, and the driving gear can be connected to the driving shaft, so that when the driving shaft rotates, the driving gear rotates accordingly. When the connection between the driving shaft and the driving gear needs to be disconnected, the second electric telescopic rod is started in the reverse direction, and the second electric telescopic rod pulls the plug-in block out of the plug-in slot, and the connection between the driving gear and the driving shaft can be disconnected.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. During the construction process, construction workers can adjust the horizontal and vertical dimensions of the lifting platform within a certain area through the adjustment mechanism to adapt it to construction needs without having to move the position again through the mobile carrier, thereby improving the convenience and efficiency of construction; the first-level anti-displacement component in the adaptive support mechanism uses buffer support to prevent the equipment from sinking and shifting on soft ground, and the second-level anti-displacement component prevents the equipment from sliding or tipping over by connecting with the inclined ground. The first-level anti-displacement component and the second-level anti-displacement component are used together to enable the equipment to operate stably on the inclined soft ground; at the same time, through the dual protection of the adaptive support mechanism and the adjustment mechanism, the construction risk of the equipment on the inclined ground is reduced, so that the equipment can quickly locate and stably operate in complex terrains such as mountainous areas and soft soil slopes where traditional equipment is difficult to intervene, thereby improving construction efficiency and flexibility and reducing construction time and labor costs; 2. The rotating assembly can flexibly, quickly and accurately control the operation of the primary anti-displacement assembly and the secondary anti-displacement assembly according to the terrain conditions, so that the equipment can operate stably on both flat soft ground and inclined soft ground, simplifying the operation process. By controlling the connecting parts, the construction personnel can flexibly control the rotation of the secondary anti-displacement assembly according to the terrain conditions, so that the equipment can adapt to various terrains such as flat soft ground and inclined soft ground; the damping sleeve limits the free rotation of the connecting sleeve through friction or damping force. When the secondary bevel gear is disconnected from the connecting sleeve, the damping sleeve can prevent the connecting sleeve from rotating freely due to inertia or external force, ensuring that the connecting sleeve remains stable; 3. In the primary anti-shift component, when the support rotates to contact the ground, the spring is in a compressed state and applies downward pressure to the support. The compression force of the spring presses the support against the ground, increasing friction and preventing the equipment from shifting during construction. At the same time, under the joint action of the spring and the damping telescopic rod, the equipment can be protected from strong wind shaking and shock absorption. Regardless of whether the strong wind blows upward or downward along the slope, it can buffer and support and absorb the impact force, so that the secondary anti-shift component is not easy to be pulled out from the ground. When used in conjunction with the secondary anti-shift component, the secondary anti-shift component can be ensured to be stably connected and the pulling force along the vertical slope can be reduced. After the secondary anti-shift component is stably connected, it can in turn prevent the primary anti-shift component from sliding along the slope. 4. The support shell is used to enhance the connection strength between the damping telescopic rod and the primary rotating seat and the support, so that the connection between the damping telescopic rod and the primary rotating seat and the support is not easy to break; the shrinkage limit block is used to prevent the damping telescopic rod and the spring from being over-pressed, thereby increasing the service life of the damping telescopic rod and the spring; when the support rotates toward the ground, the bottom of the support close to the frame side will first contact the ground, and the bottom of the support close to the frame side is arranged in an arc shape to prevent the support from being easily subjected to excessive stress at the contact part with the ground during the rotation of the support, thereby reducing the lateral shear force at the connection between the damping telescopic rod and the primary rotating seat and the support; 5. The secondary anti-shift component can be firmly connected to the ground to prevent the equipment from sliding or tipping over on the inclined surface. When the multi-stage hydraulic telescopic rod is started, the end of the multi-stage hydraulic telescopic rod will drive the protective shell away from the side of the secondary rotating seat to move below the ground, cooperate with the drill bit to drill into the ground and connect with the ground. At the same time, the protective shell can protect the internal multi-stage hydraulic telescopic rod from being affected by the soil, ensuring that the telescopic support rod can be extended smoothly; 6. When the construction site is on an inclined soft ground, the adjustment mechanism can change the inclination angle between the lifting platform and the ground until the lifting platform is adjusted to a horizontal state. At the same time, the two sets of extension plates can be adjusted separately according to the actual needs during construction, that is, by controlling the drive assembly to separately control one of the drive gears to connect with the drive shaft, so as to independently and flexibly adjust the lateral and longitudinal dimensions of the lifting platform to adapt to different terrain conditions.

DETAILED DESCRIPTION

[0028] The following is combined with Figure 1-Figure 10 This application is described in further detail.

[0029] After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of this application.

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] The present application embodiment discloses a lifting device for electric power construction. Figure 1 and Figure 2 The electric power construction lifting equipment includes a mobile carrier 1. The mobile carrier 1 adopts a crawler chassis. The crawler chassis can move smoothly on the soft ground and is not easy to sink into the soft soil. A frame 2 is fixed on the mobile carrier 1. A lifting drive device 3 is arranged on the frame 2. The lifting drive device 3 includes a hydraulic cylinder 31 and a scissor-type lifting mechanism 32; a lifting platform 4 is arranged on the top of the lifting drive device 3. An adjustment mechanism 5 is arranged between the lifting platform 4 and the frame 2. The adjustment mechanism 5 is used to extend the lateral and longitudinal dimensions of the lifting platform 4 and adjust the inclination angle between the lifting platform 4 and the ground. The frame 2 is provided with four adaptive support mechanisms 6 along its four sides. The adaptive support mechanism 6 includes a rotating component 61, a primary anti-displacement component 62, and a secondary anti-displacement component 63. The rotating assembly 61 is used to drive the primary anti-displacement assembly 62 or the secondary anti-displacement assembly 63 to rotate toward or away from the ground; the primary anti-displacement assembly 62 is used to provide buffer support for the frame 2 and prevent the mobile carrier 1 from shifting and sinking; the secondary anti-displacement assembly 63 is used to connect the frame 2 to the ground. When the electric power construction lifting equipment is on a flat soft ground, the rotating assembly 61 and the primary anti-displacement assembly 62 are started; when the electric power construction lifting equipment is on an inclined soft ground, the rotating assembly 61, the primary anti-displacement assembly 62 and the secondary anti-displacement assembly 63 are all started.

[0032] When the construction site is on a flat soft ground, the construction personnel first move the mobile carrier 1 close to the construction site, and then drive the first-level anti-displacement component 62 to rotate to the side close to the ground through the rotating component 61, so that the first-level anti-displacement component 62 abuts against the ground. The first-level anti-displacement component 62 improves the stability of the mobile carrier 1 and the frame 2 on the soft ground through buffer support, and prevents the mobile carrier 1 from shifting and settling significantly during the construction process. The construction personnel then board the lifting platform 4, wear a double-hook safety belt, and fix it to the guardrail on the lifting platform 4 through the slide rail hook. Then the lifting drive device 3 is started to lift the lifting platform 4 to the specified height, and the construction personnel can repair or replace the wires or electrical components.

[0033] When the construction site is on an inclined soft ground, after the mobile carrier 1 moves to the construction site, it is necessary to start the rotating component 61, the first anti-displacement component 62 and the second anti-displacement component 63 in the adaptive support mechanism 6. The rotating component 61 synchronously drives the first anti-displacement component 62 and the second anti-displacement component 63 to rotate toward the ground side. The first anti-displacement component 62 improves the stability of the mobile carrier 1 and the frame 2 on the inclined soft ground through buffer support, and at the same time makes it difficult for the mobile carrier 1 to shift along the inclined direction of the inclined surface and sink significantly along the vertical inclined direction during the construction process. The second anti-displacement component 63 is connected to the ground to prevent the equipment from sliding or tipping on the inclined surface. Then the construction personnel also need to adjust the inclination angle between the lifting platform 4 and the ground through the adjustment mechanism 5 to keep the lifting platform 4 in a horizontal state. Then the construction personnel board the lifting platform 4, wear a double-hook safety belt, and fix it to the guardrail on the lifting platform 4 through the slide rail hook. Then the lifting drive device 3 is started to lift the lifting platform 4 to a specified height, and the construction personnel can repair or replace the wires or electrical components.

A secondary bevel gear 615 is also sleeved on the outer side of the rotating shaft 610, a transmission bevel gear 616 is rotatably connected to the frame 2, and the transmission bevel gear 616 is meshed with both the primary bevel gear 611 and the secondary bevel gear 615. A primary rotating seat 617 is sleeved on the outer side of the rotating shaft 610, and the primary rotating seat 617 is fixedly connected to the primary bevel gear 611, and the primary anti-shift assembly 62 is arranged on the primary rotating seat 617. A secondary rotating seat 618 is sleeved on the outer side of the rotating shaft 610, and the secondary rotating seat 618 is rotatably connected to the secondary bevel gear 615, and the secondary anti-shift assembly 63 is arranged on the secondary rotating seat 618. A control connection component 619 is provided between the secondary bevel gear 615 and the secondary rotating seat 618 . The control connection component 619 is used to control the connection between the secondary bevel gear 615 and the secondary rotating seat 618 .

[0035] When the construction site is on a flat soft ground, the rotating component 61 only needs to drive the first-level anti-displacement component 62 to rotate toward the ground. First, the drive motor 614 is started. The drive motor 614 drives the worm 613 to rotate. The worm 613 drives the rotating shaft 610 to rotate through the worm gear 612. The rotating shaft 610 drives the first-level bevel gear 611 to rotate. The first-level bevel gear 611 drives the transmission bevel gear 616 to rotate through meshing. The transmission bevel gear 616 further drives the first-level rotating seat 617 to rotate, so that the first-level anti-displacement component 62 rotates toward the ground and abuts against the ground. After the first-level anti-displacement component 62 abuts against the ground, it prevents the equipment from shifting and sinking.

[0036] When the construction site is on an inclined soft ground, the rotating component 61 needs to synchronously drive the primary anti-displacement component 62 and the secondary anti-displacement component 63 to rotate toward the ground in the opposite direction. First, the secondary bevel gear 615 is connected to the secondary rotating seat 618 by controlling the connecting component 619, and then the driving motor 614 is started. The driving motor 614 drives the worm 613, the worm wheel 612, the rotating shaft 610, the primary bevel gear 611, the transmission bevel gear 616, and the secondary bevel gear 615 to rotate synchronously. At this time, the primary rotating seat 617 drives the primary anti-displacement component 62 to rotate toward the ground, and the secondary rotating seat 618 drives the secondary anti-displacement component 63 to rotate toward the ground in the opposite direction of the primary anti-displacement component 62.

[0037] Reference Figure 5 and Figure 6 The control connection component 619 includes a connection sleeve 6191 which is rotatably connected to the frame 2 and sleeved on the outside of the rotating shaft 610. The connection sleeve 6191 is fixedly connected to the secondary rotating seat 618, and the connection sleeve 6191 is located between the rotating shaft 610 and the secondary bevel gear 615. The connection sleeve 6191 is also evenly spaced along its circumference with a plurality of connection holes 6192. A connection block 6193 is slidably connected to one side of the secondary bevel gear 615 along the radial direction of the connection sleeve 6191, and the connection block 6193 can be inserted into the connection hole 6192. A first electric telescopic rod 6194 is fixedly arranged between the connection block 6193 and the secondary bevel gear 615. A damping sleeve 6195 is also fixedly arranged on the outside of the rotation connection between the connection sleeve 6191 and the frame 2.

[0038] When the connection between the secondary bevel gear 615 and the secondary rotating seat 618 is controlled by controlling the connecting component 619, the first electric telescopic rod 6194 is first started, and the output end of the first electric telescopic rod 6194 pushes the connecting block 6193 to slide toward the connecting sleeve 6191 along the radial direction of the connecting sleeve 6191, and the connecting block 6193 is inserted into the connecting hole 6192, so that the secondary bevel gear 615 can be connected to the connecting sleeve 6191. Since the connecting sleeve 6191 is fixedly connected to the secondary rotating seat 618, the secondary bevel gear 615 drives the secondary rotating seat 618 to rotate through the connecting sleeve 6191. The damping sleeve 6195 limits the free rotation of the connecting sleeve 6191 through friction or damping force. When the secondary bevel gear 615 is disconnected from the connecting sleeve 6191, the damping sleeve 6195 can prevent the connecting sleeve 6191 from rotating freely due to inertia or external force, ensuring that the connecting sleeve 6191 remains stable.

[0039] When it is necessary to disconnect the secondary bevel gear 615 from the secondary rotating seat 618, it is only necessary to reversely start the first electric telescopic rod 6194 again, and the first electric telescopic rod 6194 pulls the connecting block 6193 out of the connecting hole 6192, so that the secondary bevel gear 615 can be disconnected from the connecting sleeve 6191, so that the secondary bevel gear 615 can no longer drive the secondary rotating seat 618 and the secondary anti-shifting assembly 63 to rotate. By controlling the connecting component 619, the construction personnel can flexibly control the rotation of the secondary anti-shifting assembly 63 according to the terrain conditions, so that the equipment can adapt to various terrains such as flat soft ground and inclined soft ground.

[0040] Reference Figure 2 and Figure 3 The primary anti-displacement assembly 62 includes a support 621 spaced apart on one side of the primary rotating seat 617, and the bottom of the support 621 close to the frame 2 is arranged in an arc shape 6211. A plurality of damping telescopic rods 622 are fixedly arranged between the support 621 and the primary rotating seat 617, and a spring 623 is sleeved on the outer side of the damping telescopic rod 622. The primary rotating seat 617 is sleeved with a support shell 624 along its circumference, and the support shell 624 is slidably connected with the support 621 along the length direction of the damping telescopic rod 622. The support shell 624 is used to enhance the connection strength between the damping telescopic rod 622 and the primary rotating seat 617 and the support 621, so that the connection between the damping telescopic rod 622 and the primary rotating seat 617 and the support 621 is not easy to break. A shrinkage limiting block 625 is fixedly provided on one side of the primary rotating seat 617 close to the support 621 . The shrinkage limiting block 625 is used to prevent the damping telescopic rod 622 and the spring 623 from being over-pressed, thereby increasing the service life of the damping telescopic rod 622 and the spring 623 .

[0041] When the support 621 rotates toward the ground, the bottom of the support 621 near the rack 2 will first contact the ground. The bottom of the support 621 near the rack 2 is in an arc shape 6211, which is used to prevent the support 621 from first contacting the ground during the rotation of the support 621, thereby reducing the lateral shear force at the connection between the damping telescopic rod 622, the primary rotating seat 617 and the support 621. When the support 621 rotates to abut against the ground, the spring 623 is in a compressed state and applies downward pressure to the support 621. The compression force of the spring 623 causes the support 621 to press against the ground, increasing friction and preventing the equipment from shifting during construction. At the same time, under the joint action of the spring 623 and the damping telescopic rod 622, the equipment can be prevented from shaking in strong winds and achieve shock reduction. No matter the strong wind blows obliquely upward or downward along the slope, it can provide buffer support and absorb the impact force, so that the secondary anti-displacement component 63 is not easy to be pulled out from the ground. When used in conjunction with the secondary anti-displacement component 63, the connection of the secondary anti-displacement component 63 can be ensured to be stable and the pulling force along the vertical slope can be reduced. After the secondary anti-displacement component 63 is stably connected, it can in turn make the primary anti-displacement component 62 not easy to slide along the slope.

[0042] Reference Figure 2 and Figure 3 The secondary anti-displacement assembly 63 includes a telescopic support rod 631 rotatably connected to the secondary rotating seat 618. The telescopic support rod 631 can be telescoped along its own length direction, and a drill bit 632 is fixedly arranged at one end of the telescopic support rod 631 away from the secondary rotating seat 618. A driven bevel gear 633 is arranged on the fixed sleeve outside the telescopic support rod 631, a transmission shaft 634 is rotatably connected to the secondary rotating seat 618, and a driving bevel gear 635 is arranged on the fixed sleeve outside the transmission shaft 634, and the driving bevel gear 635 is meshed with the driven bevel gear 633. A transmission 636 is arranged on the secondary rotating seat 618, and the output shaft of the transmission 636 is connected to the transmission shaft 634, and a rotating motor 637 is arranged at one end of the input shaft of the transmission 636.

[0043] Reference Figure 3 The telescopic support rod 631 includes a plurality of protective shells 6311 which are sequentially sleeved, and adjacent protective shells 6311 are slidably connected along their length direction. A multi-stage hydraulic telescopic rod 6312 is arranged inside the telescopic support rod 631, and both ends of the multi-stage hydraulic telescopic rod 6312 are rotatably connected to the protective shell 6311 away from the secondary rotating seat 618 and the protective shell 6311 close to the secondary rotating seat 618 respectively.

[0044] When connecting with the ground through the secondary anti-shift component 63, first start the rotating motor 637, the rotating motor 637 transmits power to the transmission shaft 634 through the transmission 636, the transmission shaft 634 drives the driving bevel gear 635 to rotate, the driving bevel gear 635 is meshed with the driven bevel gear 633, and drives the telescopic support rod 631 to rotate, then the telescopic support rod 631 drives the drill bit 632 to drill toward the ground, during the drilling process, the multi-stage hydraulic telescopic rod 6312 is started, and the end of the multi-stage hydraulic telescopic rod 6312 will drive the protective shell 6311 away from the side of the secondary rotating seat 618 to move below the ground, cooperate with the drill bit 632 to drill into the ground, and connect with the ground, at the same time, the protective shell 6311 can protect the internal multi-stage hydraulic telescopic rod 6312 from being affected by the soil, ensuring that the telescopic support rod 631 can be smoothly extended until the telescopic support rod 631 drives the drill bit 632 to reach a preset depth, and then it can be firmly connected to the ground to prevent the equipment from sliding or tipping over on the inclined surface.

[0045] Reference Figure 7 and Figure 8 The adjustment mechanism 5 includes a hydraulic adjustment cylinder 51 hinged between the frame 2 and the bottom of the lifting drive device 3, and one side of the bottom of the lifting drive device 3 is rotatably connected to the frame 2. Four extension plates 52 are slidably connected inside the lifting platform 4, and two opposite extension plates 52 form a group and are located in the same plane. The two groups of extension plates 52 are staggered along the height direction of the lifting platform 4, and the moving directions of the two extension plates 52 in the same group are opposite, and the moving directions of the extension plates 52 in the two groups are perpendicular to each other.

[0046] Reference Fig. 9 and Fig.10 The lifting platform 4 is connected to a driving shaft 53 in a direction perpendicular to itself, and a power motor 54 is provided at one end of the driving shaft 53. Two driving gears 55 are provided on the outer side of the driving shaft 53, and the two driving gears 55 are distributed along the length direction of the driving shaft 53. The two groups of extension plates 52 correspond to the two driving gears 55 one by one. Each extension plate 52 is fixed with a driving rack 56. The driving racks 56 on the two extension plates 52 in each group are meshed with the corresponding driving gears 55 at the same time. A control driving assembly 57 is provided between the driving shaft 53 and the driving gear 55, and the control driving assembly 57 is used to realize the connection between the driving shaft 53 and the driving gear 55.

[0047] When the construction site is on a tilted soft ground, when adjusting the tilt angle of the lifting platform 4 through the adjustment mechanism 5, the hydraulic adjustment cylinder 51 is first started, and the hydraulic adjustment cylinder 51 pushes the bottom of the lifting drive device 3 to change the tilt angle between the lifting platform 4 and the ground until the lifting platform 4 is adjusted to a horizontal state. When adjusting the transverse and longitudinal dimensions of the lifting platform 4 through the adjustment mechanism 5, the control drive component 57 is first started to realize the connection between the drive shaft 53 and the drive gear 55, and then the drive shaft 53 is driven to rotate by the power motor 54, and the drive shaft 53 can drive the drive gear 55 to rotate, and the drive gear 55 is engaged with the drive rack 56 on the extension plate 52, driving the extension plate 52 to slide toward the outside of the lifting platform 4, and the moving directions of the two groups of extension plates 52 are perpendicular to each other, respectively adjusting the transverse and longitudinal dimensions of the lifting platform 4. The two groups of extension plates 52 can be adjusted separately according to the actual needs during construction, that is, the control drive component 57 is used to control one of the drive gears 55 to be connected to the drive shaft 53, so as to independently and flexibly adjust the transverse and longitudinal dimensions of the lifting platform 4 to adapt to different terrain conditions.

[0048] Reference Fig. 9 and Fig.10 The control driving assembly 57 includes a plug-in block 571 which is radially slidably connected to one side of the driving gear 55 along the driving shaft 53. The driving shaft 53 is provided with a plurality of plug-in slots 531 evenly spaced along its circumference, and the plug-in block 571 can be plugged into the plug-in slots 531. A second electric telescopic rod 572 is fixed between the plug-in block 571 and the driving gear 55.

[0049] When one of the driving gears 55 is controlled to be connected to the driving shaft 53 by controlling the driving assembly 57 alone, the second electric telescopic rod 572 is first started, and the second electric telescopic rod 572 pushes the plug block 571 to slide along the radial direction of the driving shaft 53 into the plug slot 531 on the driving shaft 53, so that the plug block 571 is inserted into the plug slot 531, and the driving gear 55 is connected to the driving shaft 53, so that when the driving shaft 53 rotates, the driving gear 55 rotates accordingly. When it is necessary to disconnect the connection between the driving shaft 53 and the driving gear 55, the second electric telescopic rod 572 is started in the reverse direction, and the second electric telescopic rod 572 pulls the plug block 571 out of the plug slot 531, and the connection between the driving gear 55 and the driving shaft 53 is disconnected.

[0050] The implementation principle of an electric power construction lifting equipment in an embodiment of the present application is as follows: during the construction process, the construction personnel can adjust the lateral and longitudinal dimensions of the lifting platform 4 in a certain area through the adjustment mechanism 5 to adapt it to the construction needs without having to move the position again through the mobile carrier 1, thereby improving the convenience and efficiency of the construction; the first-level anti-displacement component 62 in the adaptive support mechanism 6 uses buffer support to prevent the equipment from sinking and shifting on soft ground, and the second-level anti-displacement component 63 prevents the equipment from sliding or tipping over by connecting with the inclined ground. The first-level anti-displacement component 62 and the second-level anti-displacement component 63 are used in conjunction to enable the equipment to operate stably on the inclined soft ground; at the same time, through the dual protection of the adaptive support mechanism 6 and the adjustment mechanism 5, the construction risk of the equipment on the inclined ground is reduced, so that the equipment can be quickly positioned and stably operated in complex terrains such as mountainous areas and soft soil slopes where traditional equipment is difficult to intervene, thereby improving construction efficiency and flexibility and reducing construction time and labor costs.
