[0002] Electromechanical equipment is an integrated system of mechanical and electronic technologies. It achieves precision operation and automation through electronic control and is widely used in industry, public services, and information technology. During the maintenance of electromechanical equipment, lifting devices are indispensable tools used to elevate maintenance personnel and equipment to a suitable working height. Currently, common lifting devices on the market mainly include scissor lifts, hydraulic lifts, and electric lifts.

[0003] Traditional hydraulic lifting platforms are inefficient to maintain, require frequent personnel movement, and lack an effective locking mechanism after being raised to the correct position. They are prone to movement due to accidental contact or equipment failure, posing a risk of personnel falling. Furthermore, prolonged operation may cause the base to become unstable due to pressure, and the lack of effective isolation of the work area poses a risk of foreign objects entering or personnel accidentally touching the platform. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this application provides a lifting device for the maintenance of electromechanical equipment, which solves the technical problems of low maintenance efficiency, frequent personnel movement, lack of effective locking mechanism after lifting into position, easy movement due to accidental contact or equipment failure, risk of personnel falling, instability of the base due to pressure during long-term operation, lack of effective isolation of the work area, and danger of foreign objects entering or personnel accidentally touching the device.

[0005] To achieve the above objectives, this application provides the following technical solution: a lifting device for maintaining electromechanical equipment, comprising a base, an electric universal wheel assembly, a scissor lift module, a load-bearing plate, and a top plate.

[0006] The control mechanism includes a limit box, a first copper plate is mounted on the top of the inner cavity of the limit box, a second copper plate is mounted on the bottom of the inner cavity of the limit box, and a control switch is mounted on the bottom of the second copper plate. Hydraulic cylinder modules are evenly distributed on the bottom of the base, and the hydraulic cylinder modules are connected to the control switch through a circuit.

[0007] The base is fitted with a hollow tube on its top, and the outside of the hollow tube is connected to the exhaust horizontal pipe.

[0008] Preferably, a nut is embedded in the inner cavity of the horizontal plate, and a lead screw is threaded into the inner cavity of the nut. A second geared motor is connected to the left side of the lead screw. The second geared motor is a common geared motor in the prior art, used to drive the lead screw to rotate. The second geared motor is controlled and driven by a control module. The rotation of the lead screw can drive the nut to move left and right on the outside. The nut can drive the horizontal plate to transmit power. The horizontal plate can drive the scissor lift module to lift and lower. The combination of the horizontal plate and the scissor lift module is a common scissor lift device in the prior art.

[0009] Preferably, guide grooves are provided on both sides of the upper end of the base. A slider is slidably connected to the inner cavity of the guide groove. The slider is fixedly connected to the bottom of the horizontal plate. The slider can slide in the inner cavity of the guide groove and guide the horizontal plate, so that the horizontal plate can perform linear reciprocating motion when moving, thereby improving the stability of the horizontal plate when moving.

[0010] Preferably, a guide plate is embedded in the inner cavity of the piston rod, and the guide plate is slidably connected to the hollow column. A return spring is bolted to the left side of the piston rod, and the other end of the return spring is bolted to the top of the inner cavity of the hollow column. The guide plate can guide the piston rod, so that the piston rod can reciprocate left and right in the inner cavity of the hollow column, and prevent the piston rod from deflecting during movement. The return spring can drive the piston rod to return to its original position after the movement is completed, thereby improving the overall stability of the device.

[0011] Preferably, the top of the hollow tube is connected to a telescopic airbag, and the top of the telescopic airbag is equipped with a limiting plate. The telescopic airbag can be inflated by gas to change its height, thus providing external protection for the scissor lift module. The limiting plate can also improve the strength of the top of the telescopic airbag and prevent it from tilting easily during movement.

[0012] Preferably, the bottom of the second geared motor is connected to the upper end of the base via a platform. The second geared motor includes a motor, and a reducer is installed at the output end of the motor. The platform can protect the second geared motor, improve the stability of the second geared motor during transmission, and the reducer can increase the torque of the second geared motor during transmission, thereby improving the stability of the cross plate in the transmission of the scissor lift module.

[0013] Preferably, a first geared motor is mounted on the top of the top plate via a bracket. The output end of the first geared motor is connected to the load-bearing plate. An annular groove is mounted on the top of the top plate. A guide slider is slidably connected to the inner cavity of the annular groove. The top of the guide slider is connected to the bottom of the load-bearing plate. The first geared motor can rotate the load-bearing plate, changing its angle, thereby enabling maintenance and repair of devices in different directions. The annular groove allows the guide slider to slide inside, guiding the load-bearing plate, making it more stable during movement, and supporting the bottom of the load-bearing plate.

[0014] Preferably, a guardrail is fitted on the top of the load-bearing plate. A vertical groove is provided on the right side of the guardrail. A guardrail door is connected to the back of the inner cavity of the vertical groove via a hinge. A handle is fitted on the outside of the guardrail door. A door lock is fitted between the guardrail door and the guardrail plate. A control module is fitted on the top of the load-bearing plate. The guardrail can protect the electromechanical equipment or personnel on the top of the load-bearing plate, preventing personnel from falling from the top of the load-bearing plate and causing personal injury and economic loss. The guardrail door can close the outside of the guardrail, facilitating the transport of personnel and electromechanical equipment to the top of the load-bearing plate for lifting. The control module can control the movement of the electromechanical equipment inside the device, thereby improving the overall automation performance of the device.

[0015] Preferably, grooves are provided on both sides of the top of the horizontal plate. The top of the inner cavity of the groove is connected to the outside of the limiting cylinder by bolts. The inner cavity of the groove is slidably connected to the output end of the limiting cylinder. The groove facilitates the fixing and limiting of the control mechanism, and at the same time facilitates the up and down movement of the limiting cylinder, so as to insert into the inner cavity of the control mechanism to limit the position of the horizontal plate.

[0016] Preferably, the control mechanism is located directly below the piston rod, and the bottom of the piston rod is slidably connected to the top of the control mechanism. When the piston rod is not in operation, it can shield the top of the control mechanism to prevent external dust from entering the inner cavity of the limit box and thus affecting the normal operation of the control mechanism.

[0017] In summary, this application provides a lifting device for the maintenance of electromechanical equipment, which has the following beneficial effects:

[0018] 1. The lifting device for maintenance of electromechanical equipment, through the addition of a top plate and a load-bearing plate, allows the load-bearing plate to be driven to rotate by the top plate after the scissor lift module is lifted, thereby facilitating the movement of personnel and electromechanical equipment, enabling detection and installation in different positions, improving maintenance efficiency, and reducing the frequency of movement of maintenance personnel.

[0019] 2. The lifting device for maintenance of this electromechanical equipment, through the added control mechanism, limit cylinder and locking arm, automatically locks the position of the scissor lifting module after the top plate and load-bearing plate are lifted to the designated position by the scissor lifting module, so as to avoid accidental movement of the scissor lifting module, thereby improving the stability of the scissor lifting module, preventing movement during operation, and reducing the risk of maintenance personnel falling.

[0020] 3. The lifting device for maintenance of this electromechanical equipment, through the addition of a limit box, a first copper plate, a second copper plate and a hydraulic cylinder module, when the limit cylinder is inserted into the inner cavity of the control mechanism to lock the scissor lift module, automatically drives the first copper plate and the second copper plate to fit together, thereby activating the hydraulic cylinder module to lift the base, improving the stability of the base during operation, and at the same time avoiding the problem of the electric universal wheel assembly being squeezed for a long time during operation, which would lead to a reduction in service life;

[0021] 4. The lifting device for maintenance of this electromechanical equipment, through the addition of a horizontal plate, automatically guides the bottom of the scissor lift module to move in a straight line when the scissor lift module is in motion, thereby improving the stability of the scissor lift module during movement and avoiding the problem of unstable movement caused by the scissor lift module shaking during operation.

[0022] 5. The lifting device for maintenance of this electromechanical equipment, through the addition of a horizontal plate, hollow column, piston rod, exhaust horizontal pipe and hollow tube, automatically forces the gas inside the hollow column into the inner cavity of the hollow tube when the horizontal plate guides the scissor lift module, forming a fence around the outside of the scissor lift module. This prevents foreign objects from entering the scissor lift module during operation, or personnel from entering the scissor lift module and causing injury to personnel when the scissor lift module returns to its original position.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] This application provides a technical solution; please refer to [link / reference]. Figure 1 and Figure 2 A lifting device for maintaining electromechanical equipment includes a base 1, an electric universal wheel assembly 11, a scissor lift module 2, a load-bearing plate 4, and a top plate 3. The electric universal wheel assembly 11 is mounted at the four bottom corners of the base 1. The scissor lift module 2 is mounted on the upper surface of the base 1. The top plate 3 is mounted on the upper surface of the scissor lift module 2. A horizontal plate 6 is mounted inside the scissor lift module 2. Limit cylinders 7 are embedded on both sides of the top of the horizontal plate 6. The output end of the limit cylinder 7 is connected to a locking arm 71. Control mechanisms 8 are evenly distributed on both sides of the upper end of the base 1. Piston rods 65 are connected to both ends of the left side of the horizontal plate 6. A hollow column 64 is sleeved on the outside of the piston rod 65. The hollow column 64 is welded to the top of the base 1. An exhaust horizontal pipe 67 is connected to the outside of the hollow column 64.

[0033] The base 1 supports the scissor lift module 2, the top plate 3, and the load-bearing plate 4. The electric universal wheel set 11 is a common type of electric mobile wheel in the prior art, which can drive the base 1 to move. The base 1 is controlled by the control module 43. The scissor lift module 2 is a common type of scissor lift platform in the prior art. The scissor lift module 2 consists of multiple sets of scissor arms, guide rails, sliders, speed limiters, and overload protection devices. It is used to drive the top plate 3 to move up and down. The top plate 3 can support the load-bearing plate 4. The load-bearing plate 4 can support the electromechanical equipment and personnel. The piston rod 65 can slide in the inner cavity of the hollow column 64 and guide the horizontal plate 6 to make the horizontal plate 6 move in a straight line. The movement of the piston rod 65 inside the hollow column 64 can generate airflow, and the airflow is pressed into the inner cavity of the hollow tube 5 through the exhaust horizontal pipe 67, causing the telescopic airbag 51 to expand, thereby achieving the purpose of shielding and protecting the outside of the scissor lift module 2.

[0034] Please see Figure 6 The control mechanism 8 includes a limit box 81. A first copper plate 82 is mounted on the top of the inner cavity of the limit box 81, and a second copper plate 83 is mounted on the bottom of the inner cavity of the limit box 81. A control switch is mounted on the bottom of the second copper plate 83. Hydraulic cylinder modules 12 are evenly distributed on the bottom of the base 1. The hydraulic cylinder modules 12 are connected to the control switch through a circuit. When the second copper plate 83 contacts the first copper plate 82, current can pass through and drive the control switch to work, thereby driving the hydraulic cylinder modules 12 to work, so that the base 1 is lifted. While supporting the base 1, the electric universal wheel assembly 11 stops contacting the ground, avoiding the electric universal wheel assembly 11 from supporting the base 1 for a long time, thereby reducing its service life.

[0035] The limit box 81 can limit the limit cylinder 7 and the locking arm 71, and then limit the position of the horizontal plate 6, ultimately achieving the purpose of self-locking the scissor lift module 2. After the first copper plate 82 and the second copper plate 83 are attached and connected, the airflow can be controlled by the controller to control the hydraulic cylinder module 12, thereby making it lift and lower. The hydraulic cylinder module 12 is a common hydraulic lifting device in the prior art. The top of the first copper plate 82 is also equipped with a spring, which can make the first copper plate 82 return to its original position after the movement is completed, thereby improving the overall automation and stability of the device.

[0036] A hollow tube 5 is mounted on the top of the base 1, and the outside of the hollow tube 5 is connected to the exhaust horizontal pipe 67. The hollow tube 5 is bolted to the upper end face of the base 1, thereby improving the stability of the device in use. The hollow tube 5 is made of alloy steel and processed to ensure that the inner wall is smooth and seamless. The hollow tube 5 is rigidly connected to the upper end face of the base 1 by bolts. During the assembly process, a torque wrench is used to control the pre-tightening force to ensure the reliability of the connection. The axial channel of the hollow tube 5 and the annular gas collection chamber of the exhaust horizontal pipe 67 are smoothly connected through a specially designed three-dimensional bend. The junction adopts a double-layer fluororubber sealing sleeve structure, which effectively reduces the turbulence phenomenon of gas during transmission, reducing the working noise of the entire pneumatic system to below 58dB, and extending the service life of the seals.

[0037] Please see Figure 3 The inner cavity of the horizontal plate 6 is fitted with a nut 61, and the inner cavity of the nut 61 is threaded with a lead screw 62. The left side of the lead screw 62 is connected to a second geared motor 63. The second geared motor 63 is a common geared motor in the prior art, which is used to drive the lead screw 62 to rotate. The second geared motor 63 is controlled and driven by the control module 43. The rotation of the lead screw 62 can drive the nut 61 to move left and right on the outside. The nut 61 can drive the horizontal plate 6 to perform transmission. The horizontal plate 6 can drive the scissor lift module 2 to lift and lower. The combination of the horizontal plate 6 and the scissor lift module 2 is a common scissor lift device in the prior art.

[0038] Guide grooves 13 are provided on both sides of the upper end of the base 1. A slider is slidably connected to the inner cavity of the guide groove 13. The slider is fixedly connected to the bottom of the horizontal plate 6. The slider can slide in the inner cavity of the guide groove 13 and guide the horizontal plate 6 so that the horizontal plate 6 can move in a linear left and right reciprocating motion when it moves, thereby improving the stability of the horizontal plate 6 when it moves.

[0039] Please see Figure 4 The piston rod 65 has a guide plate embedded in its inner cavity. The guide plate is slidably connected to the hollow column 64. A return spring 66 is bolted to the left side of the piston rod 65. The other end of the return spring 66 is bolted to the top of the inner cavity of the hollow column 64. The guide plate can guide the piston rod 65, so that the piston rod 65 can reciprocate left and right in the inner cavity of the hollow column 64, and prevent the piston rod 65 from deflecting when moving. The return spring 66 can drive the piston rod 65 to return to its original position after the movement is completed, thus improving the overall stability of the device.

[0040] The top of the hollow tube 5 is connected to a telescopic airbag 51. A limit plate is installed on the top of the telescopic airbag 51. The telescopic airbag 51 can be inflated by gas to change its height and protect the exterior of the scissor lift module 2. The limit plate can also increase the strength of the top of the telescopic airbag 51 and prevent it from tilting easily during movement.

[0041] The bottom of the second geared motor 63 is connected to the upper end of the base 1 via a platform. The second geared motor 63 includes a motor, and a reducer is installed at the output end of the motor. The platform can protect the second geared motor 63 and improve the stability of the second geared motor 63 during transmission. The reducer can also increase the torque of the second geared motor 63 during transmission, thereby improving the stability of the horizontal plate 6 in transmitting the scissor lift module 2.

[0042] The top of the top plate 3 is equipped with a first reduction motor 31 via a bracket. The output end of the first reduction motor 31 is connected to the load-bearing plate 4. The top of the top plate 3 is equipped with an annular groove block 32. The inner cavity of the annular groove block 32 is slidably connected to a guide slider 33. The top of the guide slider 33 is connected to the bottom of the load-bearing plate 4. The first reduction motor 31 can rotate the load-bearing plate 4, thereby changing the angle of the load-bearing plate 4, and then performing maintenance and repair on the device in different directions. The annular groove block 32 allows the guide slider 33 to slide inside it, thereby guiding the load-bearing plate 4, making the load-bearing plate 4 more stable during movement, and also supporting the bottom of the load-bearing plate 4.

[0043] The top of the load-bearing plate 4 is equipped with a guardrail plate 41. A vertical groove is provided on the right side of the guardrail plate 41. A guardrail door 42 is connected to the back of the inner cavity of the vertical groove via a hinge. A handle is installed on the outside of the guardrail door 42. A door lock is installed between the guardrail door 42 and the guardrail plate 41. A control module 43 is installed on the top of the load-bearing plate 4. The guardrail plate 41 can protect the electromechanical equipment or personnel on the top of the load-bearing plate 4, preventing personnel from falling from the top of the load-bearing plate 4, thereby causing personal injury and economic loss. The guardrail door 42 can close the outside of the guardrail plate 41, making it convenient for personnel and electromechanical equipment to be transported to the top of the load-bearing plate 4 and driven and lifted by the load-bearing plate 4. The control module 43 can control the movement of the electromechanical equipment inside the device, thereby improving the overall automatic performance of the device.

[0044] Please see Figure 5 The top two sides of the horizontal plate 6 are provided with grooves. The top of the inner cavity of the groove is connected to the outside of the limiting cylinder 7 by bolts. The inner cavity of the groove is slidably connected to the output end of the limiting cylinder 7. The groove facilitates the fixing and limiting of the control mechanism 8, and at the same time facilitates the up and down movement of the limiting cylinder 7, so as to insert into the inner cavity of the control mechanism 8 to limit the position of the horizontal plate 6.

[0045] The control mechanism 8 is located directly below the piston rod 65. The bottom of the piston rod 65 is slidably connected to the top of the control mechanism 8. When the piston rod 65 is not in operation, it can shield the top of the control mechanism 8 to prevent external dust from entering the inner cavity of the limit box 81 and thus affecting the normal operation of the control mechanism 8.

[0046] This solution opens the connection between the fence gate 42 and the fence panel 41. Workers place the electromechanical equipment on top of the load-bearing plate 4 and enter the top of the load-bearing plate 4. The control module 43 controls the second reduction motor 63 to start, driving the lead screw 62 to rotate. Then, through the nut 61, the horizontal plate 6 slides, thereby driving the scissor lift module 2 to work as a whole, driving the top plate 3 and the load-bearing plate 4 to rise and fall. When the load-bearing plate 4 rises to the designated position, the limit cylinder 7 is activated, causing the locking arm 71 to descend and insert into the inner cavity of the limit box 81, thereby locking the position of the horizontal plate 6. The locking arm 71 also drives the first copper plate 82 to move, contacting the second copper plate 83. The hydraulic cylinder module 12 is activated by the control switch to lower the scissor lift module 2, thereby raising the base 1 and supporting its bottom. When the horizontal plate 6 slides, it drives the piston rod 65 to slide within the hollow column 64, generating airflow within the hollow column 64. This airflow is then forced into the hollow tube 5 through the exhaust horizontal pipe 67, ultimately causing the telescopic airbag 51 to inflate. This inflates the telescopic airbag 51, protecting the scissor lift module 2 from external contamination and preventing foreign objects or personnel from entering the module during operation. This would prevent injury to personnel when the module returns to its original position.

[0047] With the addition of the top plate 3 and the load-bearing plate 4, after the scissor lift module 2 is lifted, the load-bearing plate 4 can be driven by the top plate 3 to rotate, which makes it convenient for staff and electromechanical equipment to follow the movement, thereby realizing detection and installation in different positions, improving maintenance efficiency and reducing the frequency of movement of maintenance personnel.

[0048] With the addition of control mechanism 8, limit cylinder 7 and locking arm 71, when the scissor lift module 2 drives the top plate 3 and load-bearing plate 4 to rise and fall to the designated position, the position of the scissor lift module 2 is automatically locked to prevent accidental movement of the scissor lift module 2, thereby improving the stability of the scissor lift module 2, preventing movement during operation, and reducing the risk of maintenance personnel falling.

[0049] By adding a limit box 81, a first copper plate 82, a second copper plate 83, and a hydraulic cylinder module 12, when the limit cylinder 7 is inserted into the inner cavity of the control mechanism 8 to lock the scissor lift module 2, the first copper plate 82 and the second copper plate 83 are automatically driven to fit together, thereby activating the hydraulic cylinder module 12 to lift the base 1, improving the stability of the base 1 during operation, and avoiding the problem of the electric universal wheel assembly 11 being squeezed for a long time during operation, which would lead to a reduction in service life.

[0050] By adding a horizontal plate 6, the bottom of the scissor lift module 2 is automatically guided to move in a straight line when the scissor lift module 2 is moving, thereby improving the stability of the scissor lift module 2 during movement and avoiding the problem of unstable movement caused by shaking of the scissor lift module 2 during operation.

[0051] By adding a horizontal plate 6, a hollow column 64, a piston rod 65, an exhaust horizontal pipe 67, and a hollow tube 5, when the horizontal plate 6 guides the scissor lift module 2, it automatically presses the gas inside the hollow column 64 into the inner cavity of the hollow tube 5, causing the telescopic airbag 51 to rise. This forms a fence around the outside of the scissor lift module 2, preventing foreign objects from entering the scissor lift module 2 during operation, or personnel from entering the scissor lift module 2 and causing injury to personnel when the scissor lift module 2 returns to its original position.
