Description

Technical Field

[0001] This utility model relates to a technical field, specifically to a leveling device for installing power distribution cabinets. Background Technology

[0002] Distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets, and are the final-level equipment in a power distribution system. Distribution cabinets are a general term for motor control centers. Distribution cabinets are used in situations where the load is relatively dispersed and there are fewer circuits; motor control centers are used in situations where the load is concentrated and there are more circuits. They distribute the electrical energy from a circuit of the upstream power distribution equipment to the nearest load. This level of equipment should provide protection, monitoring, and control for the load.

[0003] When installing a power distribution cabinet, it is often necessary to level it. For example, patent CN221669369U discloses a leveling device for a power distribution cabinet. When using this leveling device to level the power distribution cabinet, a fixing frame is first placed on the outside of the power distribution cabinet, and then the power distribution cabinet is clamped by the clamping plate on the fixing frame, so as to install the leveling mechanism on the power distribution cabinet.

[0004] However, due to the limitations of the fixed frame shape, this leveling device imposes significant restrictions on the length and width of the distribution cabinet, which greatly limits its applicability. Utility Model Content

[0009] An air extraction mechanism is mounted on the base, and the air extraction mechanism is capable of extracting air from the connecting pipe; and

[0010] A telescopic component, which is mounted on the base.

[0011] Preferably, multiple negative suction mechanisms are provided along the length of the base; and the air extraction mechanism can simultaneously extract air from multiple connecting pipes.

[0012] Preferably, the air extraction mechanism includes: an air extraction branch pipe, an air extraction main pipe, and an air extraction pump; the air extraction branch pipe corresponds one-to-one with the connecting pipe; one end of the air extraction main pipe is closed and the other end is open; one end of the air extraction branch pipe is connected to the corresponding connecting pipe, and the other end of the air extraction branch pipe is connected to the air extraction main pipe; the air extraction pump is connected to the open end of the air extraction main pipe.

[0013] Preferably, the negative suction mechanism further includes: a first threaded rod and a piston; one end of the connecting tube is closed and the other end is open; and the open end of the connecting tube is connected to the suction cup; one end of the suction branch tube connected to the connecting tube is disposed on the side wall of the connecting tube; the first threaded rod is coaxially arranged with the connecting tube, and one end of the first threaded rod passes through the closed end of the connecting tube, and the first threaded rod is threadedly connected to the connecting tube; the piston is slidably installed in the connecting tube, and the piston is rotatably connected to one end of the first threaded rod.

[0014] Preferably, the angle of the telescopic member on the base is adjustable.

[0015] Preferably, it further includes a connecting mechanism and a driving mechanism; the telescopic member is mounted on the base via the connecting mechanism; the connecting mechanism includes: a limiting sleeve, a connecting sleeve, a rotating column, and a limiting block; one end of the limiting sleeve is fixedly mounted on the base; multiple limiting grooves are formed in the circumferential direction within the limiting sleeve; the connecting sleeve and the rotating column are coaxially fixedly mounted on the telescopic member; the connecting sleeve is sleeved on the outside of the limiting sleeve, and the connecting sleeve and the limiting sleeve are rotatably connected; the rotating column extends into the limiting sleeve; the limiting block is slidably mounted on the rotating column along the radial direction, and one end of the limiting block is inserted into the limiting groove; the driving mechanism can drive the limiting block to slide.

[0016] Preferably, the driving mechanism includes: a second threaded rod, a rotating rod, a pulley, and a flat belt; the second threaded rod and the rotating rod are arranged parallel to each other, and both the second threaded rod and the rotating rod are rotatably mounted on the rotating column; pulleys are coaxially fixed on both the rotating rod and the second threaded rod; the two pulleys are connected by a flat belt; the second threaded rod is arranged along the sliding direction of the limiting block, and the second threaded rod is threadedly connected to the limiting block.

[0017] Preferably, a friction pad is installed on the side of the base near the suction cup.

[0018] Compared with the prior art, the present invention has at least the following advantages:

[0019] 1. In this utility model, the side of the base near the suction cup is brought into contact with the side of the distribution cabinet that needs to be leveled and lifted, so that the suction cup is adsorbed onto the smooth side wall of the distribution cabinet by air pressure. Then, the air extraction mechanism is controlled to operate, and the air extraction mechanism extracts air from the suction cup through the connecting pipe, thereby firmly adsorbing the suction cup onto the distribution cabinet; this completes the installation of the leveler; it is applicable to distribution cabinets of any size, as long as the outer side wall of the distribution cabinet is smooth; finally, by controlling the extension and retraction of the telescopic component, the leveling of the distribution cabinet can be completed; and according to the actual situation, the leveler can be installed in multiple directions of the distribution cabinet at the same time, so as to achieve leveling of the distribution cabinet in multiple directions.

[0020] 2. In this utility model, the first threaded rod pushes the piston to slide along the length of the connecting pipe; when the piston slides into the connecting pipe between the air extraction branch pipe and the open end of the connecting pipe, the piston cuts off the connection between the suction cup and the air extraction branch pipe, preventing the air pump from drawing air towards the suction cup; when the piston slides into the connecting pipe between the air extraction branch pipe and the closed end of the connecting pipe, the suction cup and the air extraction branch pipe are connected through the connecting pipe, allowing the air pump to draw air towards the suction cup; therefore, when some suction cups cannot be adsorbed, the suction cups can be closed by controlling the piston to slide through the first threaded rod, thereby preventing air leakage from the suction cups when the air pump is drawing air.

[0021] 3. In this utility model, by adjusting the angle between the telescopic component and the base, the position of the suction cup can be adjusted to avoid positions on the power distribution cabinet that cannot be suctioned. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] See Figures 1-5The present invention provides an embodiment of a leveling device for installing a power distribution cabinet, comprising: a base 1, a negative suction mechanism 2, an air extraction mechanism 3, and a telescopic component 4; the negative suction mechanism 2 comprises: a suction cup 21 and a connecting pipe 22; the suction cup 21 is mounted on the base 1; the connecting pipe 22 is mounted on the base 1, and one end of the connecting pipe 22 is connected to the suction cup 21; the air extraction mechanism 3 is mounted on the base 1, and the air extraction mechanism 3 can extract air from the connecting pipe 22; and the telescopic component 4 is mounted on the base 1; specifically, the telescopic component 4 can be a cylinder, hydraulic cylinder, electric push rod, or other structure capable of telescopic pushing; furthermore, a friction pad 11 is installed on the side of the base 1 near the suction cup 21; the friction pad 11 effectively prevents the suction cup 21 from sliding on the power distribution cabinet.

[0038] In practice, the side of the base 1 closest to the suction cup 21 is brought into contact with the side of the distribution cabinet that needs to be leveled and lifted, so that the suction cup 21 is adsorbed onto the smooth side wall of the distribution cabinet by air pressure. Then, the air extraction mechanism 3 is controlled to operate, and the air extraction mechanism 3 extracts the air from the suction cup 21 through the connecting pipe 22, thereby adsorbing the suction cup 21 tightly onto the distribution cabinet. This completes the installation of the leveler. It is applicable to distribution cabinets of any size, as long as the outer side wall of the distribution cabinet is smooth. Finally, by controlling the extension and retraction of the telescopic component 4, the leveling of the distribution cabinet can be completed. Moreover, the leveler can be installed in multiple directions of the distribution cabinet at the same time according to the actual situation, so that the leveling of the distribution cabinet in multiple directions can be achieved.

[0039] See Figures 1-5 In other embodiments, the negative suction mechanism 2 is provided in multiple ways along the length of the base 1; and the air extraction mechanism 3 can simultaneously extract air from multiple connecting pipes 22; thereby improving the stability of the base 1 when it is installed on the side wall of the distribution cabinet by multiple suction cups 21.

[0040] See Figures 1-5 In other embodiments, the suction mechanism 3 includes: suction branch pipes 31, suction main pipes 32, and suction pumps 33; the suction branch pipes 31 correspond one-to-one with the connecting pipes 22; one end of the suction main pipe 32 is closed, and the other end is open; one end of the suction branch pipe 31 is connected to the corresponding connecting pipe 22, and the other end of the suction branch pipe 31 is connected to the suction main pipe 32; the suction pump 33 is connected to the open end of the suction main pipe 32. In specific implementation, the suction mechanism 3 is controlled to operate, and the suction mechanism 3 draws air towards the multiple suction branch pipes 31 through the suction pipes 22, thereby controlling the suction cups 21 to firmly adhere to the side wall of the distribution cabinet.

[0041] See Figures 1-5In other embodiments, the negative suction mechanism 2 further includes: a first threaded rod 23 and a piston 24; one end of the connecting pipe 22 is closed and the other end is open; and the open end of the connecting pipe 22 is connected to the suction cup 21; one end of the suction branch pipe 31 connected to the connecting pipe 22 is provided on the side wall of the connecting pipe 22; the first threaded rod 23 is coaxially arranged with the connecting pipe 22, and one end of the first threaded rod 23 passes through the closed end of the connecting pipe 22, and the first threaded rod 23 is threadedly connected to the connecting pipe 22; the piston 24 is slidably installed in the connecting pipe 22, and the piston 24 is rotatably connected to one end of the first threaded rod 23.

[0042] In specific implementation, rotating the first threaded rod 23 pushes the piston 24 to slide along the length of the connecting pipe 22. When the piston 24 slides into the connecting pipe 22 between the open end of the suction branch pipe 31 and the connecting pipe 22, the piston 24 cuts off the connection between the suction cup 21 and the suction branch pipe 31, preventing the suction pump 33 from drawing air towards the suction cup 21. When the piston 24 slides into the connecting pipe 22 between the closed end of the suction branch pipe 31 and the connecting pipe 22, the suction cup 21 and the suction branch pipe 31 are connected through the connecting pipe 22, allowing the suction pump 33 to draw air towards the suction cup 21. Therefore, when some suction cups 21 cannot be adsorbed, the piston 24 can be controlled to slide by the first threaded rod 23 to close the suction cups 21, thereby preventing air leakage from the suction cups 21 when the suction pump 33 is drawing air.

[0043] See Figures 1-5 In other embodiments, the angle of the telescopic member 4 on the base 1 is adjustable; by adjusting the angle between the telescopic member 4 and the base 1, the position of the suction cup 21 can be adjusted to avoid positions on the power distribution cabinet that cannot be suctioned. Furthermore, it also includes a connecting mechanism 5 and a driving mechanism 6; the telescopic member 4 is mounted on the base 1 through the connecting mechanism 5; the connecting mechanism 5 includes: a limiting sleeve 51, a connecting sleeve 52, a rotating column 53, and a limiting block 54; one end of the limiting sleeve 51 is fixedly mounted on the base 1; multiple limiting grooves 55 are opened in the circumferential direction inside the limiting sleeve 51; the connecting sleeve 52 and the rotating column 53 are coaxially fixedly mounted on the telescopic member 4; the connecting sleeve 52 is sleeved on the outside of the limiting sleeve 51, and the connecting sleeve 52 and the limiting sleeve 51 are rotatably connected; the rotating column 53 extends into the limiting sleeve 51; the limiting block 54 is slidably mounted on the rotating column 53 along the radial direction of the rotating column 53, and one end of the limiting block 54 is inserted into the limiting groove 55; the driving mechanism 6 can drive the limiting block 54 to slide.

[0044] In practice, the telescopic component 4 is rotatably mounted on the limiting sleeve 51 via the connecting sleeve 52; the telescopic component 4 is rotated to adjust the angle between the telescopic component 4 and the base 1; after the angle adjustment is completed, the drive mechanism 6 is controlled to move, and the drive mechanism 6 drives the inner block to slide outward, so that one end of the limiting block 54 is inserted into the nearest limiting groove 55, thereby fixing the angle of the telescopic component 4.

[0045] See Figures 1-5 In another embodiment, the drive mechanism 6 includes: a second threaded rod 61, a rotating rod 62, a pulley 63, and a flat belt 64; the second threaded rod 61 and the rotating rod 62 are arranged parallel to each other, and both the second threaded rod 61 and the rotating rod 62 are rotatably mounted on the rotating column 53; pulleys 63 are coaxially fixed on both the rotating rod 62 and the second threaded rod 61; the two pulleys 63 are connected by the flat belt 64; the second threaded rod 61 is arranged along the sliding direction of the limiting block 54, and the second threaded rod 61 is threadedly connected to the limiting block 54.

[0046] In practice, the rotating rod 62 is driven to rotate, and the rotating rod 62 drives the second threaded rod 61 to rotate through the pulley 63 and the flat belt 64. The second threaded rod 61 drives the limiting block 54 to slide, thus driving the limiting block 54 to slide on the rotating column 53.

[0047] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
