Description

Technical Field

[0001] The invention belongs to the technical field of switch cabinet installation and assembly, and particularly relates to a pretreatment device for switch cabinet manufacturing and assembly. Background Technique

[0002] The main function of the switch cabinet is to open, close, control and protect electrical equipment during the processes of power generation, power transmission, power distribution and power conversion in the power system. Before the switch cabinet is put into use, it is necessary to install the external shell of the switch cabinet at a designated location, and then assemble the switch cabinet components inside the shell, and finally put it into use; before installing the switch cabinet shell, it is necessary to level the installation location of the switch cabinet to avoid instability after installation, which affects the use.

[0003] Currently, when installing the switch cabinet shell, usually installers manually measure the ground at the designated installation location, and then manually level it after placing the switch cabinet. Since the installation location of the switch cabinet is relatively narrow, the installation location may only be able to accommodate the placement of the switch cabinet, making it inconvenient to level the cabinet feet of the switch cabinet, which has certain limitations. At the same time, during the leveling process, only the spirit level is used to visually observe, and there is a certain error in the leveling accuracy.

[0004] The existing leveling work before assembling the switch cabinet is rather troublesome. The limited installation location does not support leveling after placing the switch cabinet, and there is a certain error in the early measurement and leveling, resulting in unstable subsequent use of the switch cabinet. Therefore, the present invention proposes a pretreatment device for switch cabinet manufacturing and assembly. Summary of the Invention

[0005] The purpose of the present invention is to provide a pretreatment device for switch cabinet manufacturing and assembly, to solve the problems that the existing leveling work before assembling the switch cabinet is rather troublesome, the limited installation location does not support leveling after placing the switch cabinet, and there is a certain error in the early measurement and leveling, resulting in unstable subsequent use of the switch cabinet.

[0006] To solve the above technical problems, the present invention is realized through the following technical solutions:

[0007] The present invention is a pretreatment device for switch cabinet manufacturing and assembly, including a processing device and a processing system for controlling the operation of the processing device. The processing device includes an installation frame, and a sliding component is arranged inside the installation frame. Both ends of the sliding component are respectively provided with a leveling component and a leveling adjustment component. The installation frame is used to install each structural component of the processing device;

[0008] The sliding assembly includes a drive shaft. A gear is sleeved on each of the two ends of the circumferential side of the drive shaft. A rack is meshed and connected to the upper and lower ends of each gear respectively. The upper ends of the two racks are fixedly connected to the leveling assembly, and the lower ends of the two racks are fixedly connected to the ground leveling assembly. The drive shaft is driven to rotate by a drive motor, so as to drive the two meshed racks to move linearly. The lower rack is used to drive the ground leveling assembly to level the ground, and the upper rack is used to drive the leveling assembly to run to the designated installation location.

[0009] The ground leveling assembly includes a pressure sensor. The bottom of the pressure sensor is fixedly connected to the top end of a spring. The bottom end of the spring is fixedly installed with a contact block. The bottom end of the contact block contacts the ground where the switch cabinet is designated to be installed and slides back and forth along the designated direction on the ground. The pressure sensor is connected to the spring and the contact block. After the contact block touches the ground, it compresses the spring. After the spring contracts, an upward force is generated. Therefore, the pressure data received by the pressure sensor is the pressure generated by the compression deformation of the spring. Therefore, through Hooke's law, the pressure of the spring compression and the spring stiffness coefficient itself are known, so as to clearly understand the deformation amount of the spring.

[0010] The leveling assembly includes a leveling plate. The left and right sides of the leveling plate are fixedly connected to the two racks respectively; four electric push blocks are installed at the corner positions of the top of the leveling plate. The top of each electric push block contacts the bottom end of a lifting column; the four lifting columns are movably installed through a fixing frame. The top end of each lifting column is set as an inclined surface, and a leveling block is movably connected to the inclined surface of the lifting column. The other end of the leveling block is provided with a clamping groove. The clamping grooves between the two leveling blocks are clamped with each other, and several through holes are opened inside the clamping groove; a bearing plate is installed at the top of the fixing frame, and the top end of the bearing plate is fixedly connected to the switch cabinet body. The leveling plate is used to carry the upper leveling assembly and the switch cabinet body; the four electric push blocks correspond to four pressure data points. The deformation amount of the spring at each pressure data point is the upward pushing distance of the electric push block. Each lifting column corresponds to an electric push block below. When the electric push block pushes upward, the lifting column rises at the same time, so as to simulate the ground flatness of the designated installation location in advance. The leveling block is subjected to the force of moving horizontally to one side generated by the rising of the lifting column. The greater the rising distance of the lifting column, the greater the moving distance of the leveling block to the horizontal side. The clamping grooves at one end of the two leveling blocks are continuously approaching and clamped with each other. The through holes opened on its surface are used for the locking rod to pass through the through holes communicated with the four clamping grooves, so as to lock the leveling assembly and prevent the leveling block from displacing after the leveling is completed. The fixing frame plays a role in fixedly installing the lifting column to prevent the lifting column from falling during transportation. The bearing plate is used to install the switch cabinet body in advance. When the switch cabinet body is installed at the designated location, it is installed together with the bottom leveling assembly.

[0011] Preferably, a pulley is fixedly connected to each corner position at the bottom of the mounting frame, and a square groove is formed in the bottom surface of the mounting frame near each pulley. A telescopic motor is fixedly connected to the bottom of each square groove, and the bottom output end of the telescopic motor is fixedly connected to the support base; a three-way spirit level is fixedly installed at the top of the mounting frame near the leveling assembly. The pulleys are used for sliding, the telescopic motors are used for driving the support bases to telescopically move, and the four support bases are used for supporting the mounting frame and leveling the mounting frame. First, ensure that the mounting frame is in a balanced state, and the three-way spirit level is used to assist in leveling the mounting frame.

[0012] Preferably, the sliding assembly further includes a driving motor, which is fixedly connected to the outer wall of one side of the mounting frame. The output end of the driving motor penetrates through the outer wall of the mounting frame to its interior and is fixedly connected to one end of the driving shaft. The other end of the driving shaft is rotatably connected to the inner wall of the other side of the mounting frame; sliding grooves are formed in the inner walls of the opposite sides of the mounting frame, and one side of each of the four racks is slidably disposed inside the sliding grooves.

[0013] Preferably, the leveling assembly further includes a leveling plate, which is fixedly connected between the two racks located at the lower positions; fixing plates are respectively installed on both sides of the bottom of the leveling plate. A stepping motor is welded to the outer side of one of the fixing plates. The output end of the stepping motor penetrates through the fixing plate to its inner side and is fixedly connected to one end of the lead screw. The other end of the lead screw is rotatably connected to the inner side of the other fixing plate.

[0014] Preferably, the length of the lead screw is longer than the length of the switch cabinet body. Two sets of leveling assembly structures including fixing plates, lead screws and stepping motors are installed at the bottom of the leveling plate and are respectively located on both sides of the bottom surface of the leveling plate. The distance between the two lead screws is exactly equal to the width of the switch cabinet body.

[0015] Preferably, a slider is threadedly connected to each lead screw. The top of the slider is slidably connected to the bottom of the leveling plate, and the bottom end of the slider is welded to the top end of the pressure sensor; a telescopic rod is arranged inside the spring. The top end of the telescopic rod is fixedly connected to the bottom end of the pressure sensor, and the bottom end of the telescopic rod is fixedly connected to the top end of the contact block.

[0016] Preferably, the cross section of the leveling block is trapezoidal, and the contact surfaces between the leveling block and the lifting columns are inclined surfaces; the leveling assembly further includes a locking rod. When the locking rod penetrates through the through holes formed in the four clamping grooves, the four leveling blocks are locked, and at this time, the four lifting columns cannot move up and down.

[0017] Preferably, four circular mounting grooves are respectively formed at the corner positions of the top surface of the leveling plate. The bottom of each circular mounting groove is welded to the ground of the electric push block; the electric push block is movably arranged inside the circular mounting groove.

[0018] Preferably, an electric lifting rod is installed on each of the two racks located at the upper end. The two electric lifting rods are respectively located on the opposite side surfaces of the switch cabinet body, and an electric suction cup is installed at the top of each electric lifting rod. The electric suction cup adsorbs on the side surface of the switch cabinet body.

[0019] Preferably, the processing system includes a central control module, and a feedback module, a calculation module, and an adjustment module that are communicatively connected to it for control;

[0020] Central control module: It is used to receive the operation data of the processing device, organize the operation data and transfer it to the other modules of the processing system, and is also used for data transfer between the other modules;

[0021] Feedback module: It is used to receive the pressure data measured by the two pressure sensors in the leveling component, select the pressure data of two points in each pressure sensor according to the length of the switch cabinet body. The distance between the two points is exactly the length of the switch cabinet. The rectangular area enclosed by the four pressure data points selected by the two sensors is equal to the bottom area of the switch cabinet body; transfer the pressure data of the four points to the calculation module;

[0022] Calculation module: According to the pressure data of each point and combined with Hooke's law, calculate the compression length of the spring at each point where the pressure data is located, as shown in formula (1):

[0023] F = kx (1)

[0024] Where, F is the pressure data, that is, the pressure received by the spring; k is the spring stiffness coefficient; x is the deformation amount of the spring;

[0025] Thus, calculate the deformation amount x of the spring, obtain the deformation amounts of the springs at the four pressure data points, and output them to the adjustment module;

[0026] Adjustment module: It is used to adjust the upward pushing distance of the four electric push blocks according to the spring deformation amount data of the four pressure data points. Taking the pressure data point with the minimum spring deformation amount as a reference, subtract the spring deformation amount of the pressure data point with the minimum spring deformation amount from the spring deformation amounts of the other three pressure data points respectively, which is the upward pushing distance of the corresponding electric push blocks of the three pressure data points. Among them, the upward pushing distance of the electric push block at the pressure data point with the minimum spring deformation amount is 0.

[0027] The present invention has the following beneficial effects:

[0028] 1. The present invention sets a sliding component and two sets of racks, one on top of the other. When assembling a switchgear cabinet, the leveling component surrounded by the lower rack is moved directly above the designated installation location of the switchgear cabinet. The leveling component is used to level the ground flatness at the four corner points of the designated installation location. The four corner points are the four pressure data points. According to the spring deformation amounts at the four pressure data points, the upward pushing distances of the four electric push blocks are adjusted, thereby leveling the leveling component. After leveling is completed, the switchgear cabinet body installed on the leveling component surrounded by the upper rack is driven by the drive shaft to drive the gear to rotate, thereby driving the leveling component to gradually translate directly above the designated installation location. Align the four lifting columns with the four pressure data points, and place the pre-leveled switchgear cabinet body and the leveling component installed at the bottom together at the designated installation location through the electric lifting rod and the electric suction cup. This can improve the installation efficiency, is applicable to the assembly of switchgear cabinets in more spaces, and avoids hindering the assembly of the switchgear cabinet due to narrow assembly space.

[0029] 2. The present invention sets a leveling component. The contact block is installed directly below the slider. The rotation of the lead screw drives the slider to slide on the surface of the lead screw, thereby driving the lower contact block to slide on the ground in contact. Since the mounting frame has been leveled first, when the installation ground is uneven, the spring deformation amounts are different when the contact block touches the ground, so the pressures generated on the pressure sensors are different. According to the pressure data at the four pressure data points, the deformation amounts of the spring at the four pressure data points are obtained. When the deformation amount is larger, it means the ground protrusion is higher, so the upward pushing distance of the corresponding electric push block should be higher. When the deformation amount is smaller, it means the ground protrusion is smaller, so the upward pushing distance of the corresponding electric push block should be smaller. Thus, the leveling function is realized. This method can accurately measure the ground flatness of the installation location and thus accurately level it.

[0030] 3. The present invention sets a leveling component. According to the spring deformation amounts at the four pressure data points obtained by pre-measurement, the lifting heights of the corresponding four lifting columns are adjusted. The higher the ground protrusion, the higher the lifting height required for the lifting column to ensure balance. During the leveling process, the adjacent leveling blocks get closer and closer as the lifting heights of their respective lifting columns increase. After leveling is completed, the locking rod passes through the through hole on the clamping groove to lock the leveling block and prevent the leveling block from displacing, realizing the locking after leveling.
