Description

Technical Field

[0001] The invention relates to the technical field of transformer equipment transportation, and in particular to a novel instrument control box transportation device. Background Art

[0002] The transformer instrument and control box is a device used to monitor and control the operating status of the transformer. It usually contains various instruments, indicator lights, control switches and communication interfaces, etc., which are used to display the transformer's current, voltage, temperature and other key parameters, and can achieve remote control and protection of the transformer through control logic. At present, the transformer instrument and control box needs to be placed in a transport box for protection during transportation.

[0003] A Chinese patent discloses a convenient transformer transport box (authorization announcement number CN215246353U). When the four limit plates are in contact with the four sides of the transformer, the support plate stops moving down, and the transformer is completely fixed between the support plate and the limit plate. The transformer can be completely fixed inside the box without the need for a fastening device.

[0004] According to the above reference cases, the above device requires that the four limit plates are in contact with the four sides of the transformer when in use, which requires the transformer to have a cubic shape. However, in real life, the shape of the transformer instrumentation and control box is mostly a rectangular block with different lengths and widths. This will result in only two of the relative limit plates being able to stably press the transformer, while the other two sides are in an unobstructed state and cannot effectively lock the transformer.

[0005] Therefore, a new type of instrument and control box transportation device is proposed to solve the above problems. Summary of the invention

[0006] The purpose of the present invention is to provide a new type of instrument and control box transportation device in order to solve the above problems, which improves the problem that the existing transformer instrument and control box transportation device is difficult to effectively lock the transformer instrument and control box, resulting in poor transportation stability.

[0007] The present invention achieves the above-mentioned purpose through the following technical scheme: a new type of instrument and control box transportation device, including: a protection box and an adaptive locking mechanism, the adaptive locking mechanism includes a hydraulic adjustment component fixedly connected to the inside of the protection box, the opposite ends of the hydraulic adjustment component are fixedly connected with vertical pressure plates, the surface of the vertical pressure plate is installed with a telescopic component, both ends of the telescopic component are fixedly connected with side pressure plates, the horizontal cross-sectional shape of the side pressure plate is a V-shape with an opening toward the center point of the protection box, the adaptive locking mechanism utilizes the gravity of the transformer instrument and control box to synchronously lock the four corners of the transformer instrument and control box, which can simultaneously prevent the transformer instrument and control box from moving horizontally in any direction, and firmly lock the transformer instrument and control box on the top of the bearing plate, so that the transportation of the transformer instrument and control box can be more stable, so as to solve the problem that the existing transformer instrument and control box transportation device is difficult to effectively lock the transformer instrument and control box, resulting in poor transportation stability.

[0008] Preferably, the V-shaped cross-section angle of the side pressure plate is one hundred and thirty-five degrees, and one end of the side pressure plate is parallel to the vertical pressure plate, which can ensure that the side pressure plate can be effectively locked in the corner of the transformer instrumentation and control box, further improving the stability of the transformer instrumentation and control box.

[0009] Preferably, an insertion cavity is opened at one end of the vertical pressure plate, and the telescopic assembly includes a bidirectional lead screw rotatably connected to the insertion cavity, and the surfaces of two opposite threads of the bidirectional lead screw are threadedly connected with a threaded barrel, and one end of the threaded barrel passes through the insertion cavity and is fixedly connected to the side pressure plate. The telescopic assembly can adjust the spacing between the two side pressure plates according to the side width of the transformer instrument and control box, so that it can meet the needs of transformer instrument and control boxes of different specifications, thereby expanding the overall scope of application of the instrument and control box transportation device.

[0010] Preferably, the telescopic assembly also includes a servo motor fixedly connected to the surface of the vertical pressure plate, the end of the servo motor output shaft passes through the interior of the insertion cavity, the end of the servo motor output shaft is fixedly connected to a driving bevel gear, and the surface of the driving bevel gear is meshingly connected to a driven bevel gear, which can stably and effectively adjust the distance between the two side pressure plates by electric means to reduce the adjustment burden of the staff.

[0011] Preferably, the cross-sectional dimensions of the insertion cavity and the threaded cylinder are both matching rectangles; a guide cavity parallel to the insertion cavity is opened at one end of the vertical pressure plate, and two guide rods are slidably connected inside the guide cavity, and one end of the guide rod is fixedly connected to the side pressure plate, which can ensure that the side pressure plate moves in a horizontal direction and avoid the possibility of the side pressure plate rotating or offsetting.

[0012] Preferably, a protective pad is bonded to one end of the vertical pressure plate and the side pressure plate facing the center point of the protection box, and the protective pad is a rubber material component, which can not only increase the friction between the vertical pressure plate and the side pressure plate and the transformer instrument and control box to improve the locking strength of the transformer instrument and control box, but also reduce the probability of the vertical pressure plate or the side pressure plate scratching the transformer instrument and control box to ensure the appearance of the transformer instrument and control box is intact.

[0013] The beneficial effects of the present invention are:

[0014] 1. The adaptive locking mechanism uses the gravity of the transformer instrument and control box to synchronously lock the four corners of the transformer instrument and control box, which can simultaneously prevent the transformer instrument and control box from moving horizontally in any direction, and firmly lock the transformer instrument and control box on the top of the load-bearing plate, making the transportation of the transformer instrument and control box more stable, so as to solve the problem that the existing transformer instrument and control box transportation device is difficult to effectively lock the transformer instrument and control box, resulting in poor transportation stability;

The telescopic component can adjust the distance between the two side pressure plates according to the side width of the transformer instrument and control box, so that it can meet the needs of transformer instrument and control boxes of different specifications, thereby expanding the overall application scope of the instrument and control box transportation device.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Example 1: Figure 1 and Figure 2 As shown, a novel instrument control box transport device includes a protection box 100, and the protection box 100 includes:

[0024] The outer transport box is a frame-type wooden structure. The top of the outer transport box is fixedly connected with evenly distributed lifting box ears. The bottom of the outer transport box is fixedly connected with a bracket. The outer side of the outer transport box can be covered with a waterproof tarpaulin according to the transportation weather and environment. The inner side of the outer transport box is covered with tin foil wrapping paper to meet the requirements of rainproof, moisture-proof and frostproof. It should be noted that the waterproof tarpaulin and tin foil wrapping paper are structures commonly used for protection by technicians in this field. The specific model and material need to be selected according to actual needs, which will not be described in detail here.

[0025] The inner lifting box is a frame-type steel structure, and the steel structures are fixed together by bolts. The staff can adjust the overall size of the inner lifting box according to the volume of the transformer instrument box. The inner side of the inner lifting box is fixedly connected with a cable fixing frame, which can firmly lock the exposed cables outside the transformer instrument box to prevent the cables from shaking and colliding during transportation. The outer side of the inner lifting box is fixedly connected with a mechanical interlocker, an anti-loosening device, a vibration sensor and a temperature and humidity controller from top to bottom. The mechanical interlocker can stably lock the inner lifting box inside the outer transport box, and the anti-loosening device can prevent the inner lifting box from tilting in the outer transport box, so that the transformer instrument box can be transported smoothly. The vibration sensor is used to monitor and record the transportation status in real time, and the temperature and humidity controller is used to keep the interior dry and constant temperature.

[0026] The method of using the device is as follows:

[0027] The first step: connecting the transformer instrument control box with the adaptive locking mechanism 200 through the frame steel structure and the mechanical interlocker, and installing a transfer trolley or a supporting pad at the bottom of the frame steel structure.

[0028] Step 2: Assemble the cable fixing frame and the frame steel structure as a whole so that they together form a complete inner lifting box, then disconnect the transformer electric control box cable from the transformer assembly, and coil them on the cable fixing frame respectively.

[0029] Step 3: Remove the connecting bolts between the transformer instrumentation and control box and the transformer oil tank.

[0030] Step 4: Use the lifting box together with the transformer instrumentation box to lift and place it inside the outer transport box, then close the outer transport box and install relevant fixing and protective devices to meet the requirements of long-distance transportation.

[0031] Step 5. When the transformer instrument and control box arrives at the site, open the outer transport box and lift out the lifting box. Use a lifting or transfer trolley or forklift to place it on the transformer body. Connect the instrument box mounting bracket to the transformer, untie the cables and cable fixing brackets, remove the inner lifting box, and then you can take out the transformer instrument and control box for installation.

[0032] Example 2: Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a novel instrument control box transport device comprises: an adaptive locking mechanism 200, the adaptive locking mechanism 200 comprises a hydraulic adjustment assembly 210 fixedly connected to the inside of the protection box 100, the opposite ends of the hydraulic adjustment assembly 210 are fixedly connected with a vertical pressing plate 220, a telescopic assembly 230 is installed on the surface of the vertical pressing plate 220, both ends of the telescopic assembly 230 are fixedly connected with a side pressing plate 240, the horizontal cross-section shape of the side pressing plate 240 is a V-shape with an opening toward the center point of the protection box 100, the V-shaped cross-section angle of the side pressing plate 240 is one hundred and thirty-five degrees, and one end of the side pressing plate 240 is parallel to the vertical pressing plate 220;

[0033] The hydraulic adjustment assembly 210 includes a lower hydraulic cylinder, an electric cylinder and a spring fixedly connected to the inner bottom wall of the inner lifting box, the top of the lower hydraulic cylinder is fixedly connected to a bearing plate, the surface of the lower hydraulic cylinder is fixedly connected and connected to a high-pressure resistant pipe, the surface of the high-pressure resistant pipe is fixedly connected and connected to an upper hydraulic cylinder of the inner lifting box, and the output end of the upper hydraulic cylinder is fixedly connected to the vertical pressing plate 220;

[0034] When the transformer instrument and control box is placed on the top of the load-bearing plate, the transformer instrument and control box presses down the load-bearing plate, and the load-bearing plate squeezes the lower hydraulic cylinder downward. The hydraulic oil inside the lower hydraulic cylinder enters the upper hydraulic cylinder through the high-pressure resistant pipeline. The upper hydraulic cylinder expands and drives the vertical pressure plate 220 to move toward the transformer instrument and control box until the two vertical pressure plates 220 cooperate to clamp the transformer instrument and control box.

[0035] like Figure 4As shown, a plug cavity 221 is provided at one end of the vertical pressure plate 220, and the telescopic assembly 230 includes a bidirectional lead screw 234 rotatably connected to the plug cavity 221, and the surfaces of the two opposite threads of the bidirectional lead screw 234 are both threadedly connected with a threaded cylinder 235, and one end of the threaded cylinder 235 passes through the plug cavity 221 and is fixedly connected to the side pressure plate 240; the telescopic assembly 230 also includes a servo motor 231 fixedly connected to the surface of the vertical pressure plate 220, and the end of the output shaft of the servo motor 231 passes through the interior of the plug cavity 221, and the end of the output shaft of the servo motor 231 is fixedly connected to Active bevel gear 232, the surface of active bevel gear 232 is meshedly connected with driven bevel gear 233; the cross-sectional dimensions of the insert cavity 221 and the threaded cylinder 235 are both matched rectangles; one end of the vertical pressure plate 220 is provided with a guide cavity 222 parallel to the insert cavity 221, and two guide rods 236 are slidably connected inside the guide cavity 222, and one end of the guide rod 236 is fixedly connected to the side pressure plate 240; the end of the vertical pressure plate 220 and the side pressure plate 240 facing the center point of the protection box 100 is bonded with a protection pad 250, and the protection pad 250 is a rubber material component;

[0036] When it is necessary to lock transformer control boxes of different specifications, first manually control the side width of the transformer control box, and then control the servo motor 231 to rotate the active bevel gear 232 in the corresponding direction, the active bevel gear 232 drives the driven bevel gear 233 to rotate, the driven bevel gear 233 drives the bidirectional lead screw 234 to rotate, the bidirectional lead screw 234 drives the two threaded cylinders 235 to move toward or away from each other through two opposite threads, so that the two threaded cylinders 235 cooperate to drive the two side pressure plates 240 to move toward or away from each other until the spacing between the hook portions of the two side pressure plates 240 is adjusted to match the side width of the transformer control box.

[0037] When the present invention is in use, when the vertical pressing plate 220 is close to the transformer control box, the vertical pressing plate 220 simultaneously drives the two side pressing plates 240 to be close to the transformer control box through the telescopic assembly 230. When the vertical pressing plate 220 is pressed against the side of the transformer control box, the two side pressing plates 240 firmly press against the lateral corners of the transformer control box. At this time, the four corners of the transformer control box are all locked, which can simultaneously prevent the transformer control box from moving horizontally in any direction, and firmly lock the transformer control box on the top of the load-bearing plate, so that the transportation of the transformer control box can be more stable.

[0038] It should be noted that the vibration sensor, mechanical interlock, temperature and humidity controller, electric cylinder, hydraulic cylinder and servo motor 231 in the above description are all devices with relatively mature application of existing technologies. The specific models can be selected according to actual needs. At the same time, the vibration sensor, temperature and humidity controller, electric cylinder and servo motor 231 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0039] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
