DETAILED DESCRIPTION

[0023] The following will be described in detail in combination with the accompanying drawings Figures 1-4 The present application is further described in detail.

[0024] The embodiment of the present application discloses a convenient power distribution cabinet shifting and splicing device, which refers to Figure 1 and Figure 2 In the embodiment, the convenient power distribution cabinet shifting and splicing device comprises a left support 1, a right support 2, a lifting mechanism, a slide rail 3, a smooth bar 4 and a transverse adjusting assembly. The left support 1 and the right support 2 are both made of stainless steel plates, and are placed in a trench 10 in a power distribution room during operation. The lifting mechanism is provided with two, and the two lifting mechanisms are respectively arranged at the inner sides of the left support 1 and the right support 2. The slide rail 3 is provided with two, and the two slide rails 3 are respectively installed at the output ends of the two lifting mechanisms. When the lifting mechanism is started, the lifting mechanism drives the slide rail 3 to move up and down.

[0025] Meanwhile, the smooth bar 4 is provided with two, and the two smooth bars 4 are respectively slidably installed on the top of the two slide rails 3. A plurality of rollers 41 are rotatably installed in the two smooth bars 4, and the rollers 41 are in abutment with the top of the slide rail 3, so that the smooth bar 4 can slide more smoothly on the slide rail 3. The power distribution cabinet is placed on the top of the two smooth bars 4 to move forward and backward along the slide rail 3, thereby facilitating the on-site operation of the maintenance personnel.

[0026] Preferably, referring to Figure 1 and Figure 2 In the embodiment, blocking plates 31 are installed at the two ends of the two slide rails 3, and the blocking plates 31 are arranged to block the rollers 41 in the smooth bar 4, thereby preventing the smooth bar 4 from sliding out of the slide rail 3. Meanwhile, positioning plates 42 are installed at the top of one end of the two smooth bars 4, and the positioning plates 42 are arranged to effectively position the power distribution cabinet, thereby making the placement of the power distribution cabinet more convenient. When the power distribution cabinet on the smooth bar 4 is moved, the positioning plates 42 can also effectively block the power distribution cabinet.

[0027] In addition, the transverse adjusting assembly is arranged between the left support 1 and the right support 2, and the transverse adjusting assembly can not only connect the left support 1 and the right support 2 to form a bearing chassis to effectively bear, but also adjust the distance between the left support 1 and the right support 2, so that the flow bar 4 on the left support 1 and the right support 2 can adapt to power distribution cabinets of different widths.

[0028] Preferably, in the embodiment, the bearing channel steel 8 is mounted on the top outer side of the left support 1 and the top outer side of the right support 2, and the bearing channel steel 8 cooperates with the side groove 101 on the top of the ditch 10. In this way, the two bearing channel steels 8 can stably fix the left support 1 and the right support 2 in the ditch 10, and under the action of the transverse adjusting assembly, the left support 1 and the right support 2 can be stably installed in the ditch 10 of different widths, thereby improving the practicability and universality of the power distribution cabinet operation.

[0029] The structure of the lifting mechanism and the transverse adjusting assembly will be described in detail below.

[0030] Specifically, referring to Figure 1 and Figure 3 In the embodiment, the lifting mechanism includes a lead screw lifter 5, a lead screw 51, a servo motor 52, a connecting assembly, and a linkage assembly. The lead screw lifter 5 is provided in four, and the four lead screw lifters 5 are divided into two groups, each group having two. One group of lead screw lifters 5 is symmetrically mounted at the inner two ends of the left support 1, and the other group of lead screw lifters 5 is symmetrically mounted at the inner two ends of the right support 2. The lead screw 51 is provided in four, and the four lead screws 51 are threadedly connected to the output end of the lead screw lifter 5. The bottom end of the lead screw 51 located at the left support 1 penetrates the bottom of the left support 1, and the bottom end of the lead screw 51 located at the right support 2 penetrates the bottom of the right support 2.

[0031] Meanwhile, the top end of the two lead screws 51 located at the left support 1 are connected to the bottom of the two sides of one slide rail 3 through the connecting assembly, and the top end of the two lead screws 51 located at the right support 2 are connected to the bottom of the two sides of the other slide rail 3 through the connecting assembly. In this way, under the action of the lead screw lifter 5, the lead screw 51 drives the slide rail 3 and the flow bar 4 to move up and down.

[0032] The servo motor 52 is provided in two, and the two servo motors 52 are arranged correspondingly. Specifically, one servo motor 52 is mounted on the lead screw lifter 5 at the left support 1, and the output end of the servo motor 52 is connected to the input end of the lead screw lifter 5. The other servo motor 52 is mounted on the lead screw lifter 5 at the right support 2, and the output end of the servo motor 52 is connected to the input end of the lead screw lifter 5.

[0033] In addition, the linkage assembly is provided with two linkage assemblies, and the two linkage assemblies are arranged correspondingly; specifically, one linkage assembly is arranged between the two lead screw elevators 5 at the two ends of the left support 1, so that the two lead screw elevators 5 on the same side can be started simultaneously to drive the lifting of the two lead screws 51 simultaneously; and the other linkage assembly is arranged between the two lead screw elevators 5 at the two ends of the right support 2, so that the two lead screw elevators 5 on the same side can be started simultaneously to drive the lifting of the two lead screws 51 simultaneously.

[0034] Preferably, the portable power distribution cabinet displacement splicing device further comprises an electric control system, which comprises a control box composed of aluminum alloy profiles, aviation aluminum alloys, aluminum alloy hinges and other accessories, and the control box is internally provided with PLC, servo drivers, low-voltage electrical appliances and battery components, and the control box is electrically connected to the two servo motors 52 through connecting cables to control the start of the servo motors 52, and the lifting distance, speed and other parameters of the servo motors 52 can also be set on the touch screen on the surface of the control box, and the equipment can run according to the set values.

[0035] In addition, in the present embodiment, limit switches 9 are installed on the inner side of the left support 1 and the inner side of the right support 2, which cooperate with the slide rails 3 and the control box; through the setting of the limit switches 9, the position of the slide rails 3 can be sensed to prevent the slide rails 3 from descending too much and colliding with other components, so that the limit switches 9 can feedback to the control box in time, and the control box can control the entire device in time, with high automation.

[0036] In this way, when the two servo motors 52 are started simultaneously by the control box, the output ends of the two servo motors 52 drive the two lead screw elevators 5 to start, and the two lead screw elevators 5 drive the other two lead screw elevators 5 to start through the linkage assembly, so that the four lead screw elevators 5 drive the four lead screws 51 to move up and down, and the lead screws 51 on the same side drive the slide rails 3 and the fluent strips 4 to move up and down, thereby realizing the automatic lifting of the power distribution cabinets on the two fluent strips 4.

[0037] Secondly, in the present embodiment, hand wheels 55 are installed at the output ends of the two lead screw elevators 5 without servo motors 52, and the two hand wheels 55 are located on one side of the corresponding two lead screw elevators; by setting the hand wheels 55, manual operation of the hand wheels 55 can be realized when there is no power supply, and the same effect of lifting the lead screws 51 can also be achieved. It should be noted that when the servo motors 52 are started for automatic operation, the two hand wheels 55 will also rotate quickly, so the operator needs to pay attention to prevent the hand wheels 55 from colliding when working.

[0038] More specifically, referring to Figure 3 and Figure 4 In this embodiment, the connecting assembly includes a connecting sleeve 6 and a fixing plate 61. The connecting sleeve 6 is sleeved on the top end of the lead screw 51, and the inside of the connecting sleeve 6 is rotationally connected with the lead screw 51 through a bearing, so that the lead screw 51 rotates in the inside of the connecting sleeve 6; the fixing plate 61 is installed on the side of the connecting sleeve 6 away from the lead screw 51, and is stably installed on the bottom of the slide rail 3, so as to realize the mutual connection of the lead screw 51 and the slide rail 3, so that the lead screw 51 drives the slide rail 3 to move up and down when moving up and down.

[0039] At the same time, referring to Figure 1 and Figure 3 In this embodiment, the linkage assembly includes a shaft coupling 53 and a connecting rod 54. The shaft coupling 53 is provided with a total of four, two of which are installed at the output end of the servo motor 52 away from the two lead screw lifts 5, and the other two are installed at the input end of the other two lead screw lifts 5 away from the hand wheel 55; the connecting rod 54 is provided with a total of two, one of which is fixedly connected between the two shaft couplings 53 located in the left support 1, so as to realize the mutual linkage between the two lead screw lifts 5; the other is fixedly connected between the two shaft couplings 53 located in the right support 2, so as to realize the mutual linkage between the two lead screw lifts 5.

[0040] In this way, by setting the linkage structure of the shaft coupling 53 and the connecting rod 54 cooperating with each other, the two lead screw lifts 5 located on the same side can be started at the same time, and then the two lead screws 51 on the same side can be lifted at the same time.

[0041] Specifically, referring to Figure 1 In this embodiment, the transverse adjustment assembly includes a left adjustment sleeve 11, a right adjustment sleeve 21, a reverse tooth lead screw 7, and an adjustment rotating block 71. One end of the left adjustment sleeve 11 is fixedly installed at the inner side of the left support 1; one end of the right adjustment sleeve 21 is fixedly installed at the inner side of the right support 2; the center axes of the left adjustment sleeve 11 and the right adjustment sleeve 21 are on the same straight line, and the inner sides of the left adjustment sleeve 11 and the right adjustment sleeve 21 are provided with reverse tooth threads; the two ends of the reverse tooth lead screw 7 are threadedly connected with the left adjustment sleeve 11 and the right adjustment sleeve 21 respectively; the adjustment rotating block 71 is installed on the middle outer side wall of the reverse tooth lead screw 7.

[0042] When the rotating block 71 is adjusted by rotating, the left adjusting sleeve 11 and the right adjusting sleeve 21 can be clamped or loosened to each other under the action of the mutual screw connection of the positive and negative teeth at the two ends of the positive and negative toothed rod 7 and the positive and negative teeth inside the left adjusting sleeve 11 and the right adjusting sleeve 21, so that the distance between the left support 1 and the right support 2 can be adjusted, and then the load-bearing channel steel 8 on the left support 1 and the right support 2 can be respectively installed in cooperation with the side groove 101 on the top of the ditch 10 on both sides.

[0043] Preferably, in the embodiment, guide columns 12 are symmetrically installed on the inside of the left support 1 and located between the two left adjusting sleeves 11; sleeves 22 are symmetrically installed on the inside of the right support 2 and located between the two right adjusting sleeves 21, and the sleeves 22 and the guide columns 12 are in sliding cooperation with each other, so that the sleeves 22 are sleeved on the outside of the guide columns 12, thereby not only facilitating the combination of the left support 1 and the right support 2 into one, but also achieving the effect of effective mutual bearing to improve the stability of the entire support.

[0044] Therefore, by setting the left support 1, the right support 2, the lifting mechanism, the sliding rail 3, the flow bar 4 and the transverse adjusting assembly in cooperation with each other, the power distribution cabinet can be effectively lifted and moved to the specified position, which not only reduces the labor intensity of the operation and maintenance personnel, realizes accurate and reliable splicing of the power distribution cabinet body and elements, but also improves the work efficiency and facilitates on-site operation.

[0046] 1) Insert the power plug of the control box into the AC 220V power socket, and place the power switch in the open position.

[0047] 2) Then place the entire device on the ditch 10 where the power distribution cabinet is installed, and adjust the left support 1 and the right support 2 to be far away from each other by the transverse adjusting assembly, so that the load-bearing channel steel 8 on the left support 1 and the right support 2 is clamped on the side groove 101 on the top of the ditch 10 on both sides.

[0048] 3) Return the flow bar 4 to the original position, select the manual gear, press the down button, and lower the flow bar 4 to about 5mm below the horizontal plane of the left support 1 and the right support 2 to the limit switch 9.

[0049] 4) Place the power distribution cabinet above the left support 1 and the right support 2, and measure the distance from the bottom of the power distribution cabinet to the flow bar 4, and set the lifting distance on the touch screen to be greater than this distance by 5-10mm.

[0050] 5) Turn the manual / automatic button on the control box to the automatic position, press the up button, so that the two servo motors 52 are started at the same time, the output of the two servo motors 52 drives the two lead screw elevators 5 to start, and the two lead screw elevators 5 drive the other two lead screw elevators 5 through the linkage assembly to start, so that the four lead screw elevators 5 drive the four lead screws 51 to move upwards, so that the lead screws 51 on the same side drive the sliding rails 3 and the flow bars 4 to move upwards, and then the power distribution cabinet is automatically lifted and moved upwards, and then the power distribution cabinet is manually pushed to the corresponding position.

[0051] 6) Loosen the left support 1 and the right support 2 by the transverse adjustment assembly, move the device to the next work station, and enter the next cycle.

[0052] 7) After the work is completed, turn off the power, clean the impurities, and maintain the device for the next use.
