Description

Technical Field

[0001] The invention belongs to the technical field of switch cabinet assembly, and in particular relates to an auxiliary pre-positioning device for switch cabinet assembly. Background Art

[0002] When assembling the switch cabinet, the side panels need to be assembled to the cabinet body. To facilitate the assembly of the side panels to the cabinet body, Figure 1 As shown, a square hole is provided on the cabinet body 1, and an insert block 33 for inserting into the square hole is fixed on the side panel 2, or an insert block 33 is fixed on the cabinet body 1, and a square hole for inserting the insert block 33 is provided on the side panel 2, and the insert block 33 is inserted into the square hole to achieve pre-positioning, and then the side panel 2 can be welded (or other connection methods) to the cabinet body 1.

[0003] During the actual operation, it is difficult for the staff to translate the vertical side panel to the cabinet and install it on the cabinet. Usually, the staff hold the side panel by hand to make the side panel inclined, and the lower end of the side panel is located close to the cabinet so that it can be supported by the ground. Then the upper part of the side panel is pushed to be in contact with the cabinet. However, due to the setting of the plug block, the plug block may cause interference in this process, and the side panel cannot be completely in contact with the cabinet. It is still necessary to translate the side panel. In this case, the side panel is in contact with the ground after assembly, and can be installed with the help of the ground. In the case where there is a gap between the side panel and the ground after assembly, it is necessary to always keep a gap between the side panel and the ground when assembling the side panel, which is difficult for the staff to operate. In the process of translating the side panel to the cabinet, the staff's fingers are easily squeezed between the side panel and the cabinet. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a switch cabinet assembly auxiliary pre-positioning device to solve the problem that the fingers of the workers are easily squeezed between the side panel and the cabinet body.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] The auxiliary pre-positioning device for assembly of a switch cabinet comprises a movable seat, on which a clamping mechanism for fixing a cabinet body and a supporting mechanism for installing a side panel are installed, the supporting mechanism comprises an inclined platform fixed on the movable seat, a slide groove opened on the movable seat, a support rod slidably connected in the slide groove, and a support plate hinged on the upper end of the support rod, the upper end of the inclined platform is inclined toward the direction of the support rod, and a space for placing the side panel is formed between the lower end of the inclined platform and the edge of the movable seat; a plurality of first mounting grooves and a plurality of second mounting grooves are arranged on the support plate, the first mounting groove and the second mounting groove are alternately distributed and the number is the same; a first sliding rod is slidably connected in the first mounting groove, a first electromagnetic suction cup is fixed at one end of the first sliding rod located in the first mounting groove, a second sliding rod is slidably connected in the second mounting groove, and a roller is rotatably connected at one end of the second sliding rod located in the second mounting groove, the axis of the roller is parallel to the direction of hinged deflection of the support plate, and a limiting mechanism for limiting the first sliding rod and the second sliding rod is installed on the support plate.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] The side panel is placed on the moving seat, the lower end of the side panel is attached to the inclined platform, and the upper end of the side panel is against the support plate, so that the first electromagnetic suction cup extends out of the first installation slot, the side panel is in contact with the first electromagnetic suction cup, and the side panel is adsorbed by the first electromagnetic suction cup, so that the side panel can be transported to the cabinet to be installed through the moving seat. The side panel is placed at an angle for easy transportation and prevents the side panel from falling off the moving seat. The first electromagnetic suction cup is prevented from moving during transportation by a limiting mechanism.

[0009] After the side panel is transported to the cabinet, the cabinet is clamped by a clamping mechanism to prevent the cabinet from moving during assembly. The roller is extended out of the second installation slot, and the first electromagnetic suction cup is retracted into the first installation slot. The side panel and the roller are in contact, and the support rod is slid toward the cabinet. The support rod drives the support plate to push the side panel to a vertical state. During this process, the support plate is deflected, and the contact position between the support plate and the side panel changes. The roller is set so that the roller can rotate relative to the side panel to prevent the support plate from scratching the side panel. The limiting mechanism is used to prevent the roller from retracting into the second installation slot during assembly.

[0010] After the side panel is in a vertical state, the first electromagnetic suction cup is extended out of the first installation slot again, the upper part of the side panel is fixed by the first electromagnetic suction cup, and then the support rod is continued to slide to horizontally move the side panel so that the side panel is assembled on the cabinet.

DETAILED DESCRIPTION

[0018] The present invention is further described in detail below with reference to the accompanying drawings, and specific implementation methods are given.

[0019] like Figure 2 As shown, the switch cabinet assembly auxiliary pre-positioning device includes a moving seat 4, on which a clamping mechanism for fixing the cabinet body 1 and a supporting mechanism for installing the side panel 2 are installed. A walking wheel 5 is installed at the lower end of the moving seat 4. The walking wheel 5 uses a universal wheel structure with a foot brake in the prior art. When the moving seat 4 does not need to move, the universal wheel is limited by the foot brake. A push handle is installed at the upper end of the moving seat 4. The push handle and the clamping mechanism are respectively located on both sides of the moving seat 4. The push handle includes a vertical rod 7 connected to the moving seat 4 along a vertical sliding manner. A suction cup 6 is fixed at the lower end of the vertical rod 7. The staff drags the moving seat 4 to walk through the vertical rod 7, pulls the vertical rod 7 upward, and the suction cup 6 does not contact the ground, so the moving seat 4 can be moved. When assembling the side panel 2, the vertical rod 7 is pressed downward so that the suction cup 6 is adsorbed on the ground, thereby having a certain fixing effect on the moving seat 4. The push handle and the clamping mechanism are respectively located on both sides of the movable seat 4, which on the one hand prevents the push handle from interfering with the work of the clamping mechanism, and on the other hand facilitates setting the suction cup 6 on the push handle to prevent uneven force on both sides of the movable seat 4 when the side panel 2 is installed, thereby causing the movable seat 4 to flip over.

[0020] The supporting mechanism includes an inclined platform 34 fixed on the moving seat 4, a slide groove 29 opened on the moving seat 4, a support rod 8 slidably connected in the slide groove 29, and a support plate 10 hinged to the upper end of the support rod 8. The inclined platform 34 is located on the side of the moving seat 4 where the clamping mechanism is set. The upper end of the inclined platform 34 is inclined toward the direction of the support rod 8, and a space for placing the side panel 2 is formed between the lower end of the inclined platform 34 and the edge of the moving seat 4.

[0021] Combination Figure 3 , Figure 4 As shown, a plurality of first mounting grooves 11 and a plurality of second mounting grooves 12 are provided on the support plate 10, and the first mounting grooves 11 and the second mounting grooves 12 are alternately distributed and the number is the same. A first slide bar 17 is slidably connected in the first mounting groove 11, and a first electromagnetic suction cup 13 is fixed at one end of the first slide bar 17 located in the first mounting groove 11. At least two first slide bars 17 are provided in one first mounting groove 11 to improve the connection stability with the first electromagnetic suction cup 13, and one end of the plurality of first slide bars 17 extending out of the first mounting groove 11 is fixed on the first connecting plate 24. The first electromagnetic suction cup 13 uses an electromagnetic suction cup 6 that passes direct current, and a direct current power supply (such as a battery) can be installed on the support plate 10. A second electromagnetic suction cup 9 is fixed at the lower part of the support rod 8, and the second electromagnetic suction cup 9 also uses a direct current power supply, and the direct current power supply is installed on the support rod 8.

[0022] A second slide bar 15 is slidably connected in the second mounting groove 12, and one end of the second slide bar 15 located in the second mounting groove 12 is rotatably connected to a roller 14, and the axis of the roller 14 is parallel to the direction of hinged deflection of the support plate 10. Two second slide bars 15 are provided in one second mounting groove 12, and the two second slide bars 15 are respectively located at both ends of the roller 14, and one end of the two second slide bars 15 extending out of the second mounting groove 12 is fixed on the second connecting plate 23.

[0023] A limiting mechanism for limiting the first slide bar 17 and the second slide bar 15 is installed on the support plate 10. A first connecting rod 18 is fixed between the first slide bars 17 extending from the plurality of first mounting grooves 11. Since there are a plurality of first slide bars 17 in each first mounting groove 11, the first connecting rod 18 is fixed between the plurality of first connecting plates 24 for easy connection. A second connecting rod 16 is fixed between the second slide bars 15 extending from the plurality of second mounting grooves 12. Since there are a plurality of second slide bars 15 in each second mounting groove 12, the second connecting rod 16 is fixed between the plurality of second connecting plates 23 for easy connection.

[0024] The second spring 25 is fixed between the first connecting rod 18 and the second connecting rod 16 and the support plate 10. Specifically, a spring slot is provided on the support plate 10, and the end of the second spring 25 is fixed in the spring slot, so that when the second spring 25 contracts, the first connecting rod 18 and the second connecting rod 16 can be attached to the support plate 10. The limiting mechanism includes a limiting block slidably connected to the support plate 10, and the limiting block includes a first limiting portion 19, a second limiting portion 20, and a hand-held portion 21 connected between the first limiting portion 19 and the second limiting portion 20. The first limiting portion 19 and the second limiting portion 20 are used to limit the first connecting rod 18 and the second connecting rod 16, respectively. Figure 5 As shown, the first limiting part 19 and the second limiting part 20 are provided with wedge surfaces at opposite ends, the wedge surfaces face the support plate 10, and the end of the wedge surfaces facing the support plate 10 is inclined toward the hand-held part 21. A strip-shaped ring-shaped limiting ring 22 is fixed on the support plate 10, and the hand-held part 21 is slidably connected in the limiting ring 22. The hand-held part 21 is made of iron, and magnetic blocks for adsorbing the hand-held part 21 are fixed at both ends of the limiting ring 22. In actual use, the magnetic blocks can be replaced by electromagnets.

[0025] When in use, the side panel 2 is placed on the moving seat 4, the lower end of the side panel 2 is in contact with the ramp 34, and the upper end of the side panel 2 is against the support plate 10. At this time, the staff slides the handheld portion 21 to make the first limit portion 19 slide toward the first connecting rod 18. The wedge surface of the first limit portion 19 clamps the first connecting rod 18, and as the first limit portion 19 slides, the first connecting rod 18 is pressed toward the support plate 10, so that the first slide bar 17 drives the first electromagnetic suction cup 13 to extend out of the first installation slot 11, and the side panel 2 and the first electromagnetic suction cup 13 are in contact, and the side panel 2 is adsorbed by the first electromagnetic suction cup 13, so as to facilitate the transportation of the side panel 2 to the cabinet 1 to be installed through the moving seat 4. At this time, the support rod 8 is located at the end of the slide slot 29 away from the ramp 34 to prevent the support rod 8 from sliding during transportation when the side panel 2 is against the support plate 10.

[0026] After the side panel 2 is transported to the cabinet 1, the cabinet 1 is clamped by the clamping mechanism to prevent the cabinet 1 from moving during assembly. The second limiting portion 20 is slid toward the second connecting rod 16, so that the wedge surface of the second limiting portion 20 presses the second connecting rod 16 to move toward the support plate 10, so that the roller 14 extends out of the second installation slot 12, and the first connecting rod 18 is reset by the second spring 25, driving the first electromagnetic chuck 13 to retract into the first installation slot 11. At this time, the side panel 2 and the roller 14 are in contact.

[0027] The support rod 8 is slid toward the direction close to the cabinet body 1, and the support rod 8 drives the support plate 10 to push the side plate 2 to a vertical state. During this process, the support plate 10 is deflected, and the contact position between the support plate 10 and the side plate 2 changes. By setting the roller 14, the roller 14 can rotate relative to the side plate 2 to prevent the support plate 10 from scratching the side plate 2.

[0028] After the side panel 2 is in a vertical state, the side panel 2 and the second electromagnetic suction cup 9 on the support rod 8 are attached to each other, and the lower part of the side panel 2 is fixed by the second electromagnetic suction cup 9. The hand-held part 21 is slid again to make the first electromagnetic suction cup 13 extend out of the first mounting groove 11, and the upper part of the side panel 2 is fixed by the first electromagnetic suction cup 13. Then the support rod 8 is continued to be slid to horizontally move the side panel 2 so that the side panel 2 is assembled on the cabinet body 1.

[0029] In another embodiment of the present invention, Figure 6 As shown, the clamping mechanism includes a clamping rod 3 fixed on both sides of the moving seat 4, the ends of the clamping rod 3 extend out of the moving seat 4, and a slide groove 29 is provided on the opposite side of the two clamping rods 3. The slide groove 29 is located at one end of the clamping rod 3 extending out of the moving seat 4. A clamping block 30 is slidably connected in the slide groove 29, and a first spring 31 is fixed between the clamping block 30 and the inner wall of the slide groove 29. It also includes an inflation mechanism for introducing gas into the slide groove 29. The inflation mechanism includes an inflation barrel 26 fixed on the moving seat 4, a piston is slidably connected in the inflation barrel 26, a piston rod 27 is fixed between the piston and the support rod 8, and an inflation tube 28 is connected between the inflation barrel 26 and the slide groove 29. A flexible pad is fixed on the clamping surface of the clamping block 30, and a pressure relief hole 32 connected to the slide groove 29 is opened on the clamping rod 3, and a pressure limiting valve is installed in the pressure relief hole 32.

[0030] During specific use, when transporting the side panel 2, the cabinet body 1 can be clamped between the two clamping rods 3. During the sliding process of the support rod 8, the support rod 8 drives the piston rod 27 to slide, so that the gas in the inflation barrel 26 is discharged into the slide groove 29. The gas enters the slide groove 29 and pushes the clamping block 30 to slide out of the slide groove 29 to clamp the cabinet body 1. After the clamping block 30 clamps the cabinet body 1, the gas introduced into the slide groove 29 can no longer continue to make the clamping block 30 move, so the air pressure in the slide groove 29 increases, and the gas is discharged through the pressure relief hole 32.

[0031] In another embodiment of the present invention, the support rod 8 is a telescopic rod. The support rod 8 is an electric telescopic rod or other rod with telescopic function in the prior art. The specific telescopic structure of the support rod 8 is not described in detail in this embodiment. After the side panel 2 is in a vertical state, the vertical position of the side panel 2 is adjusted by telescoping the support rod 8 so that it can be better assembled on the cabinet 1. During adjustment, the side panel 2 needs to be located in the space formed by the moving seat 4, the two clamping rods 3 and the cabinet 1 to avoid the moving seat 4 interfering with the position adjustment of the side panel 2.

[0032] In another embodiment of the present invention, a slide seat (not shown in the figure) is vertically slidably connected to the movable seat 4, and the support mechanism is installed on the slide seat. The height of the side panel 2 can be adjusted by adjusting the height of the entire support mechanism through the vertical sliding of the slide seat. Compared with the telescopic support rod 8, this embodiment can first adjust the height of the support mechanism, and then the side panel 2 can be rotated to a vertical state and then directly translated to complete the assembly, but it is not suitable for assembly situations where the lower end of the side panel 2 needs to be in contact with the ground.
