Description

Technical Field

[0001] The present invention relates to the technical field of transportation equipment, and in particular to a cabinet detection and transportation device and a vertical transportation detection method for cabinets. Background Art

[0002] Cabinets, also known as electrical cabinets, distribution cabinets, etc., are metal cabinets used for installing electrical equipment, and are usually used in power distribution systems, control systems, and data processing equipment, etc. In the power system, cabinets are widely used for installing switchgear, protection equipment, control equipment, and related measuring instruments, etc.

[0003] Currently, the transportation methods of cabinets and electrical cabinets mainly involve pushing the cabinets down and lying them horizontally, and then using a trolley or a forklift for handling. In this way, since cabinets are usually relatively heavy, it is difficult to directly load or unload them on the trolley, and often additional hoisting equipment is required as an auxiliary, increasing the complexity and cost of the operation. In addition, since some cabinets are equipped with specific electrical devices inside and do not allow the transportation method of pushing down and lying horizontally, vertical transportation must be adopted. Manual pushing of the trolley is not only time-consuming and laborious, but also when transporting on an uneven slope ground, if not detected in time, it is easy to cause the cabinet to deviate too much in angle, increasing the risk of tipping over.

[0004] Although using a forklift improves the transportation efficiency, it cannot ensure the stability of the cabinet on uneven ground and is easy to cause the cabinet to deviate. Moreover, when the road surface is bumpy, the vibration and collision with the forklift may damage the electrical devices inside the cabinet and the external structure, affecting the safety and service life of the equipment. Therefore, it is necessary to provide a cabinet detection and transportation device and a vertical transportation detection method for cabinets that are convenient for vertical hoisting and transportation, effectively prevent the cabinet from tipping over during transportation, improve safety, and reduce the collision and vibration of the cabinet during transportation. Summary of the Invention

[0005] The present invention proposes a cabinet detection and transportation device and a vertical transportation detection method for cabinets to solve the problems raised in the above background art.

[0006] To achieve the above object, the present invention adopts the following technical solutions:

[0007] A cabinet detection and transportation device includes a pushable main frame. The middle part of the main frame is the mounting area for the cabinet. A hydraulic lifting structure is installed at the top of the main frame. There are several movable hooks with load sensors on the hydraulic lifting structure. A controller with an alarm function and a hydraulic pump are respectively installed on the side of the main frame. The hydraulic lifting structure is connected to the hydraulic pump. Each load sensor and the hydraulic pump are electrically connected to the controller to form a multi-functional cabinet detection and transportation device integrating detection, control, and alarm. The load sensor can also be a pressure sensor, both of which are existing mature technologies and are not uniquely limited here.

[0008] Preferably, the hydraulic lifting structure includes a long square frame composed of two long steel bars and two short steel bars. The movable hook is installed on the two long steel bars. A chute is provided at the top of the long steel bar, and tooth grooves are provided at the top on both sides of the chute. Four hydraulic cylinders are installed at the top of the main frame. The telescopic ends of the hydraulic cylinders all face upward, and the telescopic ends of the hydraulic cylinders are fixedly connected to the four corners of the bottom surface of the long square frame through flange plates respectively. Each hydraulic cylinder is connected to a hydraulic pump through a pipe.

[0009] Preferably, the movable hook includes a hanging frame sleeved on the outer peripheral side of the long steel bar. A hook is fixed to the bottom surface of the hanging frame. Two through holes are provided at the top of the hanging frame. A guide rod is sleeved in the through hole. A slider is fixed to the bottom of the guide rod. The slider is located in the chute and slides in contact with the chute. The slider slides back and forth along the length direction of the chute in the chute, driving the hanging frame to move synchronously through the suspension rod. The guide rod also plays a guiding role in the up and down movement of the hanging frame.

[0010] Preferably, a stop block is fixed to the top of the guide rod. A spring is sleeved on the outer peripheral surface of the guide rod, and the upper end of the spring contacts the hanging frame, and the lower end of the spring contacts the slider. When the hook is not hanging the switch cabinet, the hanging frame can always maintain a certain distance from the chute by using the elastic force of the spring, so that the tooth groove is separated from the tooth block, thereby ensuring that the slider can slide in the chute. The stop block is used to limit the hanging frame to prevent the hanging frame from detaching from the guide rod.

[0011] Preferably, the weighing sensor is installed on the top of the slider. A pressing block is provided on the inner top surface of the hanging frame. The pressing block is located directly above the weighing sensor, and the pressing block contacts the weighing sensor as the hanging frame moves. Tooth blocks corresponding perpendicularly to the tooth grooves are symmetrically provided on the inner top surface of the hanging frame. When the pressing block contacts the weighing sensor, the tooth block is embedded in the tooth groove to prevent the slider from sliding. At the same time, the distance from the bottom surface of the pressing block to the top of the weighing sensor is greater than the distance from the tooth block to the inner bottom surface of the tooth groove, preventing the bottom surface of the tooth block from contacting the inner bottom surface of the tooth groove prior to the contact of the pressing block with the weighing sensor, and avoiding the tooth block from dispersing the weight of the switch cabinet, resulting in inaccurate detection by the weighing sensor.

[0012] Preferably, the main frame includes four columns. Three bottom beams are connected to the lower part of the columns, and three top beams are connected to the upper ends of the columns to form a one-sided open cubic frame. Universal wheels are also installed on the bottom surfaces of the columns. The columns and the top beams are all I-beams with a specification of not less than 125 mm, and the bottom beam is a square steel with a specification of 100*100*2 mm.

[0013] Preferably, the hydraulic cylinders are symmetrically mounted on two opposite roof beams through flange plates, the controller is mounted on the side bottom beam, and a guardrail is hinged on the column corresponding to the open side of the cubic frame. The guardrail plays a protective role to prevent the cabinets from falling out of the hanging area when the cabinet accidentally topples, improving safety.

[0014] A crossbeam is connected between the two columns on the side opposite to the guardrail, a fixing plate is mounted on the crossbeam, the hydraulic pump is mounted on the fixing plate, a push-pull grip is further provided on the column, and a buzzer and an alarm lamp are provided on the controller.

[0015] A vertical transportation detection method for cabinets based on the cabinet conveying device as described above includes the following steps:

[0016] 1) Open the guardrail, face the open side of the cubic frame towards the cabinet, and push the main frame so that the main frame receives the cabinet from the open side into the hanging area. Move the hanging frame so that the hanging frame slides through the slider in the chute to adjust the position and match the size of the cabinet. Hang the cabinet with the hook and close the guardrail;

[0017] 2) Start the hydraulic pump through the controller. The hydraulic pump drives the hydraulic cylinders to work, thereby lifting the long rectangular frame upward. At the same time, the hanging frame moves downward, so that the pressing block presses on the weighing sensor, and the tooth block is embedded in the tooth groove to prevent the hanging frame from moving along the long steel during the hanging and transportation;

[0018] 3) When the hydraulic cylinders work to lift, the four weighing sensors are simultaneously pressed to detect the weight pressure when the hook lifts, and transmit the detection data to the controller. If any one of the weighing sensors fails to detect the weight or there is a large deviation of a predetermined value from the weight detected by other weighing sensors, that is, the cabinet is not correctly hung on the four hooks, the controller issues a warning through the buzzer and the alarm lamp;

[0019] 4) When the hydraulic pump works, the controller automatically adjusts the corresponding output power of the hydraulic pump according to the weight detected by the weighing sensor;

[0020] 5) During the transportation journey, the four weighing sensors continuously detect the weight pressure received. When the weight detected by any one or more weighing sensors exceeds the predetermined difference from the weight detected by other weighing sensors, that is, the overall angle of the transportation device deviates too much and there is a risk of tipping over, the controller issues a warning through the buzzer and the alarm lamp;

[0021] 6) After moving to the end position, the hydraulic cylinders descend and reset, place the cabinet on the ground, disengage the hook, and at the same time the spring resets to lift the hanging frame, and the tooth block disengages from the tooth groove, so that the hanging frame can move along the chute through the slider to carry out the next transportation work.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] The cabinet conveying device of the present invention has one side of the main frame set as the open side and the middle part set as the hanging side, which can realize directly hanging the cabinet on the ground without using additional lifting equipment to lift the cabinet body, avoiding the problem that the cabinet is not easy to load due to its large weight, occupying a small space, and realizing vertical hanging and transportation at the same time. The moving hook can adjust its position on the hydraulic lifting structure to realize the hanging and transportation of cabinets of different sizes. By using multiple weighing sensors to individually detect the moving hook, it can achieve a multi-functional effect of real-time detection, automatic power control, and timely alarm, effectively preventing the situation that the cabinet topples horizontally due to excessive angle deviation during transportation. Using a lifting hook to lift and transport the cabinet reduces the contact with the cabinet and simultaneously reduces the collision and vibration of the cabinet during transportation, with good protection performance.

[0024] The cabinet transportation detection method of the present invention adopts the method of directly hanging and lifting the cabinet in place without using additional tools to lift and rotate the cabinet. It is convenient and fast to hang, and at the same time, it can realize the detection of the fixing of the lifting hook to the cabinet before hanging, the automatic adjustment of the power of the hydraulic pump during hanging, and the real-time detection and alarm of the angle deviation of the cabinet during transportation. The operation is convenient and the transportation is stable.

[0025] The present invention realizes a multi-functional effect of not requiring additional lifting equipment, being able to automatically adjust the power, and real-time detecting the angle deviation of the cabinet by directly hanging and lifting the cabinet on the ground, ensuring the smooth and safe transportation process.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Embodiment 1, referring to Figure 1-3 , a cabinet detection and transportation device, including a pushable main frame 1. The middle part of the main frame 1 is a mounting area 11 for cabinets. A hydraulic lifting structure 2 is installed on the top of the main frame 1. A plurality of movable hooks 3 with weighing sensors 31 are provided on the hydraulic lifting structure 2. A controller 4 with an alarm function and a hydraulic pump 5 are respectively installed on the side of the main frame 1. The hydraulic lifting structure 2 is connected to the hydraulic pump 5. Each of the weighing sensors 31 and the hydraulic pump 5 is electrically connected to the controller 4 to form a multifunctional cabinet detection and transportation device integrating detection, control, and alarm. The weighing sensor 31 can also be a pressure sensor, both of which are existing mature technologies and are not uniquely defined here.

[0035] The hydraulic lifting structure 2 includes a rectangular frame composed of two long steels 21 and two short steels 22. The movable hook 3 is installed on the two long steels 21. A chute 23 is provided at the top of the long steel 21. Tooth grooves 24 are provided on the tops of both sides of the chute 23. Four hydraulic cylinders 25 are installed on the top of the main frame 1. The telescopic ends of each of the hydraulic cylinders 25 face upward, and the telescopic ends of the hydraulic cylinders 25 are fixedly connected to the four corners of the bottom surface of the rectangular frame through flanges 26 respectively. Each of the hydraulic cylinders 25 is connected to the hydraulic pump 5 through a pipe.

[0036] The movable hook 3 includes a hanging frame 32 sleeved on the outer peripheral side of the long steel 21. A hook 33 is fixed to the bottom surface of the hanging frame 32. Two through holes 34 are provided at the top of the hanging frame 32. A guide rod 35 is sleeved in the through hole 34. A slider 36 is fixed to the bottom of the guide rod 35. The slider 36 is located in the chute 23 and slides in contact with the chute 23. The slider 36 slides back and forth in the chute 23 along the length direction of the chute 23, driving the hanging frame 32 to move synchronously through the suspension rod. The guide rod 35 also plays a guiding role in the up and down movement of the hanging frame 32.

[0037] A stop block 38 is fixed to the top of the guide rod 35. A spring 37 is sleeved on the outer peripheral surface of the guide rod 35, and the upper end of the spring 37 contacts the hanging frame 32, and the lower end of the spring 37 contacts the slider 36. When the hook 33 is not hanging the switch cabinet, the elastic force of the spring 37 enables the hanging frame 32 to always maintain a certain distance from the chute 23, so that the tooth groove 24 is disengaged from the tooth block 310, thereby ensuring that the slider 36 can slide in the chute 23. The stop block 38 is used to limit the hanging frame 32 to prevent the hanging frame 32 from detaching from the guide rod 35.

[0038] The weighing sensor 31 is installed on the top of the slider 36. A pressing block 39 is provided on the inner top surface of the hanging frame 32. The pressing block 39 is located directly above the weighing sensor 31, and the pressing block 39 moves with the hanging frame 32 and contacts the weighing sensor 31. Tooth blocks 310 perpendicular to the tooth groove 24 are symmetrically provided on the inner top surface of the hanging frame 32. When the pressing block 39 contacts the weighing sensor 31, the tooth block 310 is inserted into the tooth groove 24 to prevent the slider 36 from sliding. At the same time, the distance from the bottom surface of the pressing block 39 to the top of the weighing sensor 31 is greater than the distance from the tooth block 310 to the inner bottom surface of the tooth groove 24, preventing the bottom surface of the tooth block 310 from contacting the inner bottom surface of the tooth groove 24 prior to the contact of the pressing block 39 with the weighing sensor 31, and avoiding the tooth block 310 from dispersing the weight of the switch cabinet, resulting in inaccurate detection by the weighing sensor 31.

[0039] The main frame 1 includes four columns 13. Three bottom beams 15 are connected to the lower part of the columns 13, and three top beams 14 are connected to the upper ends of the columns 13 to form a one-sided open cubic frame. Universal wheels 7 are also installed on the bottom surfaces of the columns 13. Both the columns 13 and the top beams 14 are I-beams with a specification of not less than 125 mm, and the bottom beam 15 is a square steel with a specification of 100*100*2 mm.

[0040] The hydraulic cylinders 25 are symmetrically installed on two opposite top beams 14 through flange plates 26. The controller 4 is installed on the side bottom beam 15. A protective fence 6 is installed on the column 13 corresponding to the open side of the cubic frame through hinges. The protective fence 6 plays a protective role, preventing the switch cabinet from falling out of the mounting area 11 accidentally when it is accidentally toppled, and improving safety.

[0041] A crossbeam 51 is connected between two columns 13 on the side opposite to the protective fence 6. A fixing plate 52 is installed on the crossbeam 51. The hydraulic pump 5 is installed on the fixing plate 52. A push-pull grip 12 is also provided on the column 13. A buzzer and an alarm light are provided on the controller 4.

[0042] A method for vertically transporting and detecting a switch cabinet based on the switch cabinet conveying device as described above includes the following steps:

[0043] 1) Open the protective fence 6, orient the open side of the cubic frame towards the switch cabinet, and push the main frame 1 so that the main frame 1 receives the switch cabinet from the open side into the hanging area 11. Move the hanging frame 32 so that the hanging frame 32 slides through the slider 36 in the chute 23 to adjust the position and match the size of the switch cabinet. Hang the switch cabinet with the hook 33 and close the protective fence 6;

[0044] 2) Start the hydraulic pump 5 through the controller 4. The hydraulic pump 5 drives the hydraulic cylinder 25 to work, thereby lifting the long rectangular frame upward. At the same time, the hanging frame 32 moves downward, so that the pressing block 39 presses on the weighing sensor 31, and the tooth block 310 is embedded in the tooth groove 24 to prevent the hanging frame 32 from moving along the long steel 21 during the hanging and transportation;

[0045] 3) When the hydraulic cylinder 25 works to lift, the four weighing sensors 31 are simultaneously pressed to detect the weight pressure when the hook 33 lifts, and transmit the detection data to the controller 4. If any one of the weighing sensors 31 fails to detect the weight or there is a large deviation of a predetermined value from the weight detected by other weighing sensors 31, that is, the switch cabinet is not correctly hung on the four hooks 33, the controller 4 issues a warning through the buzzer and the alarm light;

[0046] 4) When the hydraulic pump 5 works, the controller 4 automatically adjusts the corresponding output power of the hydraulic pump 5 according to the weight detected by the weighing sensor 31;

[0047] 5) During the transportation journey, the four weighing sensors 31 continuously detect the weight pressure received. When the weight detected by any one or more weighing sensors 31 exceeds a predetermined difference from the weight detected by other weighing sensors 31, that is, the overall angle of the transportation device deviates too much and there is a risk of tipping over, the controller 4 issues a warning through the buzzer and the alarm light;

[0048] 6) After moving to the end position, the hydraulic cylinder 25 descends and resets, places the switch cabinet on the ground, disengages the hook 33. At the same time, the spring 37 resets to lift the hanging frame 32, and the tooth block 310 disengages from the tooth groove 24, so that the hanging frame 32 can move along the chute 23 through the slider 36 to perform the next transportation work.

[0049] Example 2, refer to Figure 4 - Figure 5 , switch cabinet detection and transportation device calculation;

[0050] Assume that this device needs to lift a switch cabinet weighing 2000 kg. The top beam 14 is made of I-beam with a specification of 125x125x5x5 as a component to bear 1 / 2 of the load, with a length of 2000 mm and fixed connections at both ends.

[0051] According to the equipment drawings and steel structure design standards and other materials, the force is calculated as follows ( Figure 4 ):

[0052] The following table is the force calculation of this device

[0053]

[0054] The following table is the internal force calculation of this device

[0055]

[0056]

[0057] The calculation formula is the bending moment and deformation calculation formula on page 42 of the Practical Handbook of Static Calculation of Building Structures (Third Edition), as Figure 5 shown.

[0058] The following table is the strength design value of the top beam 14 of this device

[0059]

[0060] The following table is the safety check of the top beam 14 of this device

[0061]

[0062] As can be seen from the above, the bending deformation value of this device is 1.88 mm, which is less than the specified deflection limit requirement of 5 mm. Therefore, the switch cabinet transportation tooling can be used safely.

[0063] Example 3. Reference Figure 6 , anti-tipping calculation;

[0064] Assume that the switch cabinet is fastened to this device. The total mass of the switch cabinet and this device is 1 t, the center of gravity is 0.3 m from the ground, the maximum width is 1.150 m, the running speed is 3 km / h, and the braking time is 3 s.

[0065] As Figure 6 shown, 1. When the outer frame is fastened to the internal objects, an overall analysis should be carried out; 2. Assume that the coordinate of wheel 1 is (0,0), and the coordinate of the center of gravity is (0.575 m, 0.3 m); 3. The force analysis is as shown in the above figure. The critical condition for tipping is F pull = 0 and Fy2 = 0.

[0066] The following table is the force calculation of this device

[0067]

[0068]

[0069] The following table shows the internal force calculation of this device (taking moments about (0,0))

[0070]

[0071] The following table shows the anti-overturning check of this device (the total moment is 0, i.e., M1 = M2)

[0072]

[0073] As can be seen from the above, when this device transports the panel cabinet on the flat surface, the actual operating acceleration is a = 18.78, which is less than the critical acceleration a max = 450. Therefore, it can play a role in preventing overturning.

[0074] The present invention realizes the multi-functional effects of no need for additional lifting equipment, automatic power adjustment and real-time detection of the angle deviation of the panel cabinet by directly hanging and lifting the panel cabinet on the ground, ensuring the smooth and safe transportation process.

When the weight detected by any one or more weighing sensors (31) exceeds a predetermined difference from the weight detected by other weighing sensors (31), that is, the overall angle of the transportation device deviates too much and there is a risk of tipping over, the controller (4) issues a warning through the buzzer and the alarm lamp; 6) After moving to the end position, the hydraulic cylinder (25) descends and resets, places the switchgear cabinet on the ground, disengages from the hook (33). At the same time, the spring (37) resets and pushes up the hanging frame (32), and the tooth block (310) disengages from the tooth groove (24), so that the hanging frame (32) can move along the sliding groove (23) through the slider (36) to carry out the next transportation work.
