Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of lifting equipment, and in particular relates to a lifting device for a transformer substation. Background Art
[0002] In large-scale high-voltage substations, since the high-voltage transmission lines that receive electricity are mostly laid overhead, when entering the high-voltage substation, in order to adapt to the low-altitude laying of transmission lines and improve the safety of personnel patrolling the high-voltage substation, steel frame supporting insulation facilities are used to provide traction support for the high-voltage transmission lines, so as to achieve a better bearing effect and reduce the traction load on the substation facilities.
[0003] In the process of erecting these steel frames, after the vertical steel frame and the ground piles are installed, the transverse steel frame needs to be hoisted on the top of the vertical steel frame, first pre-installed, then installed, and finally the insulation installation.
[0004] At present, the transverse steel frame is connected and fixed by square box sections, and the connection length can be selected according to the erection length requirements.
[0005] During the hoisting process, steel ropes are first inserted into both sides of the transverse steel frame, and rope locks are used to tighten the steel ropes on both sides of the transverse steel members. Then the crane's rope hook is hung on the rope buckle of the steel rope, and the crane retracts the rope to drive the transverse steel frame up. The transverse steel frame can be lifted to the top of the vertical steel frame through the movement of the crane, the rotation of the crane platform, and the extension and retraction and flipping of the boom. After the initial connection and installation, the rope lock is released to separate the steel rope from the transverse steel frame.
[0006] However, under this lifting method, the steel rope loops are prone to slide on both sides of the transverse steel frame due to the lifting movement and the imbalance of gravity at the lifting position. This situation often occurs during the lifting and translation process and the lowering process. Especially in the batch lifting work of large-scale high-voltage substations, it is necessary to ensure both the safety of the lifting and the efficiency of the lifting, which puts a great test on the operating experience of the crane operators and the personnel who climb to the vertical steel frame area; secondly, when the steel rope loops are installed on both sides of the transverse steel frame, it is difficult to ensure the gravity balance of the transverse steel frame at the lifting position. Therefore, in common cases, the transverse steel frame is tilted during the lifting and lowering process. When the top of the vertical steel frame is placed below, it is easy to cause the transverse steel frame to slip off the vertical steel frame on one side. The personnel who operate the crane and the personnel who climb to the vertical steel frame area need to adjust the position of the transverse steel frame in time.
[0007] Therefore, in order to hoist the transverse steel frame in the substation more safely and efficiently, it is necessary to provide a lifting device that can automatically adjust the center of gravity of the load and has high hoisting adaptability and stronger hoisting stability.

The rear side plate 6 is thickened and weighted to ensure the weight balance of the front and rear positions of the support plate 5. The front side plate 6 is bolted to a motor 7.

The bearing is inserted into the bearing groove by interference, and the swivel is inserted into the inner ring of the bearing.
[0036] Both sides of the lead screw 8 are screwed with a moving plate 9, and the screw holes of the moving plates 9 at the front and rear positions are screwed in opposite directions, so that when the lead screw 8 rotates, the moving plates 9 at the front and rear positions move towards or in opposite directions; a slider 10 is integrally arranged at the bottom of the moving plate 9, and sliding openings are arranged at the front and rear sides of the support plate 5, and the slider 10 is slidably arranged in the sliding openings, and the bottom bolts of the slider 10 are fixed to clamp the leg column 11;
[0037] The operation of the motor 7 drives the screw 8 to rotate, thereby driving the movable plates 9 at the front and rear positions to move towards or in the opposite directions, thereby achieving the front and rear positions of the clamping leg column 11 to move towards or in the opposite directions.
[0038] The left and right sides of the beam plate 1 are bolted to fix the mounting plate 30, and the mounting plate 30 is bolted to fix the electro-hydraulic push rod 31, and the top rod of the electro-hydraulic push rod 31 passes through the mounting plate 30 and is flange-connected to the vertical bearing plate 28.

[0042] Through the operation of motor 2 101, the rotary shovel plate 19 is driven to rotate at the lower part of the clamping leg column 11, thereby changing the direction of the rotary shovel plate 19. The load-bearing and rotation-bearing arrangement in the clamping leg column 11 enables the rotating force axis 15 to not only rotate stably in the clamping leg column 11, but also provide strong guarantee for the stability of the rotary shovel plate 19 supporting the transverse steel frame.

The distance between the laser head of the laser ranging head 23 and the port of the mounting hole is 3 mm, which can avoid damage to the laser ranging head 23 during the clamping process.
[0046] The laser distance measuring head 23 is provided to calculate the distance between the clamping leg column 11 and the transverse steel frame when the clamping leg column 11 clamps the transverse steel frame, thereby providing strong support for the automatic control of the start and stop operation of the clamping drive mechanism.

[0050] By extending and retracting the top rod of the electro-hydraulic push rod 2 33 , the support plate 34 is driven to move left and right on the beam plate 2 26 , thereby changing the hanging position of the traction rope 38 on the beam plate 26 and changing the inclination state of the towed transverse steel frame.
[0051] See also Figure 1 and Figure 5The control mechanism includes a driver group 43 bolted in the control box 41. The driver group 43 consists of 8 drivers, of which the power control input ends of two drivers are connected to the power controlled ends of the motor 17 and the electro-hydraulic push rod 131 through cables, the power control input ends of four drivers are connected to the power controlled ends of the motor 2101 through cables, and the power control input ends of the last two drivers are connected to the power controlled ends of the electro-hydraulic push rod 233 through cables, and the main power input ends of all drivers are connected to the external power supply through a drag cable. The development board 44 is screwed fixed in the control box 41 and located at the side of the driver group 43, and the battery 45 is screwed fixed in the control box 41 and located at the side of the development board 44.

Under such a setting, the charging head 46 can be connected through a charging line to charge the battery 45. The power output end of the transformer is connected to the power pin of the power module of the development board 44 through a cable, and the battery 45 is used to supply power for the operation of each module in the development board 44 .
[0052] See also Figure 6 The development board 44 is provided with a transmission control module, which includes a distance data acquisition module, a pressure data acquisition module and a balance data acquisition module. The distance data acquisition module is used to receive the distance signal of the laser distance measuring head 23 and convert the distance signal into distance data. The signal line of the laser distance measuring head 23 is connected to the signal input pin of the distance data acquisition module; the pressure data acquisition module is used to receive the pressure signal input by the pressure sensor 20 and convert the pressure signal into a pressure value. The transmission line of the pressure sensor 20 is connected to the signal access pin of the pressure data acquisition module; the balance data acquisition module is used to receive the inclination signal obtained by the inclination sensor 42 in real time, and convert the inclination signal into an inclination value. The transmission line of the inclination sensor 42 is connected to the signal input pin of the balance data acquisition module;
[0053] The distance data acquisition module, the pressure data acquisition module and the balance data acquisition module are connected to the data distribution module, which is connected to the analysis and processing module. The data distribution module is used to input the distance data, the pressure value and the inclination angle value into the analysis and processing module in a chronological order. The analysis and processing module is connected to the drive control module 1 and the drive control module 3. The analysis and processing module is used to analyze the distance data and the pressure data, and issue an instruction to stop the operation of the clamping drive mechanism to the drive control module 1. The analysis and processing module is also used to analyze the balance data, and issue an instruction to stop the operation of the push mechanism to the drive control module 3.
[0054] When clamping, when the distance data obtained by the analysis and processing module is 5 cm, the analysis and processing module sends an automatic operation instruction to the drive control module, so that the clamping drive mechanism continues to operate in the original operation mode. When the average pressure value collected by the pressure data acquisition module reaches 800 Newtons, the analysis and processing module sends a stop operation instruction to the drive control module, and the clamping drive mechanism stops running. In this process, the analysis and processing module sends a priority instruction to the drive control module, and the drive control module does not execute the peripheral wireless control signal.
[0055] After the clamping action is completed, when one side of the clamped transverse steel frame is overweight, when the analysis and processing module receives an inclination angle value greater than 0 degrees, the analysis and processing module sends a driving instruction to the drive control module 3, controls the pushing mechanism in the light direction to push the support frame 34 to move in the heavy direction, and controls the pushing mechanism in the heavy direction to push the support frame 34 to move toward the middle side of the beam slab 26, thereby changing the lifting position of the traction rope 38 and changing the lifting center of gravity. When the inclination angle value is equal to 0 degrees, the analysis and processing module sends a stop operation instruction to the drive control module 3.
[0056] The transmission and control module also includes a wireless signal transceiver module, which is used to receive the wireless control signal of the peripheral device in real time. The wireless transmission protocol can be reached between the peripheral laptop computer and the wireless signal transceiver module, and the driver control program is loaded in the peripheral laptop computer; the wireless signal transceiver module is connected to the signal processing module, and the signal processing module is used to divide and process each wireless control signal; the signal processing module is connected to the signal dividing module, and the signal dividing module is connected to the drive control transmission module 1, the drive control transmission module 2 and the drive control transmission module 3, and the signal dividing module is used to transmit the divided and processed wireless control signal to the drive control transmission module 1, the drive control transmission module 2 and the drive control transmission module 3 respectively;
[0057] The drive control module 2 is used to control the operation of the load-bearing rotation drive mechanism.
[0058] After the wireless control command is issued by the external laptop computer, it is received by the wireless signal transceiver module, and the control signal is divided and processed by the signal processing module, and the signal division module inputs the drive control module 1, the drive control module 2 and the drive control module 3 respectively, and the drive control module 1 controls the clamping and reverse operation of the clamping drive mechanism. After the clamping action is automatically completed, it takes 20 seconds to receive the reverse and clamping direction control command in the wireless control signal, and after receiving the reverse operation command, the drive control module 1 controls the clamping drive mechanism to run in the reverse direction;
[0059] During the process from when the analysis and processing module issues a control instruction to the drive control and transmission module 3 until the drive control and transmission module 3 completely executes the instruction, the drive control and transmission module 3 does not receive the wireless control signal. After the drive control and transmission module 3 completely executes the automatic operation instruction for 20 seconds, the drive control and transmission module 3 can receive the wireless control signal.
[0060] When the pressure data received by the analysis and processing module exceeds 0 Newton, the drive control module 2 cannot receive the wireless control signal. When the pressure data received by the analysis and processing module is 0 Newton, the drive control module 2 can receive the wireless control signal, thereby controlling the operation of the load-bearing rotation drive mechanism.
[0061] The working principle of this embodiment is as follows:
[0062] Clamping drive mechanism, clamping leg column 11, rotary shovel plate 19: The clamping drive mechanism drives the clamping leg column 11 to clamp the transverse steel frame, and the rotary shovel plate 19 supports the bottom four sides of the transverse steel frame, which makes the lifting stability of the transverse steel frame stronger;
[0063] Clamping leg column 11, clamping drive mechanism, pressure distance sensing mechanism and control mechanism: the pressure distance sensing mechanism feeds back distance data and pressure data to the control mechanism in real time, and when the clamping leg column 11 approaches the transverse steel frame, the wireless control is disengaged and the clamping drive mechanism is automatically controlled, which can effectively realize the support of the transverse steel frame by the clamping leg column 11 and avoid excessive or insufficient clamping pressure of the clamping leg column 11 on the transverse steel frame;
[0064] Inclination sensor 42, control mechanism, and pushing mechanism: The control mechanism receives the inclination signal obtained by the inclination sensor 42 in real time, converts the inclination signal into an inclination value, and sequentially analyzes and controls the pushing mechanism to change the hoisting position of the traction rope 38 on the beam slab 26, and level the lifting center of gravity, thereby leveling the tilted state of the transverse steel frame during the lifting process.
