In addition, features defined as "first" or "second" may explicitly or implicitly include one or more such features, and are used to distinguish and describe features, without distinction of order or importance. In the description of the present invention, unless otherwise specified, "multiple" means more than two.

[0037] like Figure 1-5 A power room gantry frame includes: a frame body 1 and an electric hoist 2; a crossbeam 11 is provided on the top of the frame body 1, and the electric hoist 2 is movably installed on the crossbeam 11; and further includes: an auxiliary plate 3 and an auxiliary lifting rope 4;

[0038] The auxiliary plate 3 is provided with a first lifting connector 31 in the middle and second lifting connectors 32 at both ends in the length direction; the electric hoists 2 are provided in pairs on the crossbeam 11, and the electric hoists 2 can be moved to any position between the middle and the end of the crossbeam 11;

[0039] When one of the electric hoists 2 moves to the middle of the beam 11 , the steel wire rope 21 of the electric hoist 2 is detachably connected to the first lifting connector 31 below, and one end of the auxiliary lifting rope 4 is detachably connected to the second lifting connector 32 ;

[0040] When the two electric hoists 2 move to the ends of the beam 11 respectively, the steel wire rope 21 of the electric hoist 2 is detachably connected to the second lifting connector 32 below, and one end of the auxiliary lifting rope 4 is detachably connected to the first lifting connector 31 .

[0041] This solution provides a gantry for an electrical room, which arranges electric hoists 2 in pairs on the frame body 1. The working number of the electric hoists 2 can be selected as needed, and the connection position of the wire rope 21 can also be selected. In combination with the connection of the auxiliary lifting rope 4 to the auxiliary plate 3, this solution can realize multi-mode lifting of equipment, solving the problem that the lifting method of the existing gantry is too single and cannot adapt to the lifting of multiple equipment.

[0042] Specifically, the electric hoist 2 moves the crossbeam 11 installed on the frame body 1 in a well-known manner, and the electric hoist 2 lifts or lowers the equipment by winding or unwinding the wire rope 21; on this basis, the present solution adds an auxiliary plate 3; the auxiliary plate 3 is provided with a first lifting connector 31 in the middle and a second lifting connector 32 at both ends; in one embodiment, the connection between the auxiliary plate 3 and the wire rope 21 or the auxiliary lifting rope 4 of the present solution is detachable, so it is possible to choose whether to use the auxiliary plate 3 as needed; when there is no auxiliary plate 3, it can be used directly as a conventional lifting gantry; in one embodiment, when the equipment is long and light in weight, the auxiliary plate 3 can be considered to be used, and only a single electric hoist 2 can be used, such as Figure 3 , the electric hoist 2 moves to the middle of the beam 11 and lowers the wire rope 21 to the first lifting connector 31 connected to the middle of the auxiliary plate 3. The second lifting connectors 32 at both ends of the auxiliary plate 3 are respectively connected to one end of the auxiliary lifting rope 4, and the other ends of the auxiliary lifting rope 4 are respectively connected to the two ends of the equipment in the length direction; start the electric hoist 2, and the wire rope 21 drives the auxiliary plate 3 to rise as it is wound, and drives the auxiliary lifting rope 4 to lift the equipment upward.

[0043] In one embodiment, when the equipment is heavy, two electric hoists 2 are used, such as Figure 1 , the two electric hoists 2 are respectively moved to the left and right ends of the beam 11, and the wire rope 21 is lowered to the second lifting connector 32 connected to the end of the auxiliary plate 3, and the first lifting connector 31 in the middle of the auxiliary plate 3 is respectively connected to one end of the auxiliary lifting rope 4, and the other end of the auxiliary lifting rope 4 is connected to the center of gravity position of the equipment; the electric hoists 2 at the left and right positions are started, and the wire ropes 21 on both sides are synchronously driven to drive the auxiliary plate 3 to rise as they are wound, and drive the auxiliary lifting rope 4 to lift the center of gravity position of the equipment.

[0044] Optimally, it further includes: a moving component 5;

[0045] The moving assembly 5 includes: a moving wheel 51 and a wheel driver 52;

[0046] Multiple moving wheels 51 are respectively installed at the bottom of the frame body 1; the wheel driver 52 is installed on the frame body 1, and the output end of the wheel driver 52 is connected to one of the moving wheels 51, which is used to drive the moving wheel 51 to rotate and drive the frame body 1 to move.

[0047] This solution preferably installs moving wheels 51 at multiple positions of the frame body 1, and drives the moving wheels 51 to rotate through the wheel driver 52, driving the frame body 1 to move, so that the frame body 1 can be automatically moved to a specific position in the workshop, eliminating the need for workers to push it, and reducing the labor cost of transferring equipment in the workshop.

[0048] The wheel driver 52 is a well-known mechanism with a driving rotation function, such as a motor, or a combination of a motor and a reducer.

[0049] Optimally, it further comprises: a guide rod 6 and a connecting arm 7;

[0050] The guide rod 6 is vertically installed on the side frames 12 on both sides of the frame body 1; one end of the connecting arm 7 is detachably connected to the guide rod 6, and the other end of the connecting arm 7 is detachably connected to the auxiliary plate 3, and the connecting arm 7 drives the auxiliary plate 3 to move along the length direction of the guide rod 6.

[0051] This solution installs guide rods 6 on the side frames 12 of the main frame 1. The guide rods 6 extend vertically. When some heavier equipment is hoisted and the main frame 1 is moved within the factory, the equipment is prone to shaking during movement, and may then sway with the wire rope 21. This can be particularly problematic when the ground is uneven, causing the center of gravity to become unstable. To address this, this solution installs guide rods 6 on the side frames 12 on both sides. One end of a connecting arm 7 is connected to the guide rod 6 in a known manner, and the other end is connected to the auxiliary plate 3. In this way, the connecting arm 7, auxiliary plate 3, and connecting arm 7 are arranged in a straight line and move along the length of the guide rod 6, which can limit the equipment's swing angle and maintain its stability during transfer.

[0052] Optimally, the second lifting connector 32 is provided with a card interface 321; one end of the connecting arm 7 is provided with a first card post 71;

[0053] The first clamping post 71 is clamped to the clamping interface 321 , so that one end of the connecting arm 7 is detachably connected to the auxiliary board 3 .

[0054] The connection method between the connecting arm 7 and the auxiliary plate 3 can be achieved in a well-known manner. In the optimal embodiment, the second lifting connector 32 is provided with a card interface 321. The first card connection column 71 of the connecting arm 7 only needs to be carded into the card interface 321 to enable the connecting arm 7 to be quickly connected to the auxiliary plate 3, thereby reducing the difficulty of installation.

[0055] Optimally, a gap is formed between the inner wall of the card interface 321 and the outer wall of the first clamping post 71 ; the first clamping post 71 is downwardly clamped to the card interface 321 , and the first clamping post 71 is limited and movable in the card interface 321 .

[0056] In this solution, the inner diameter of the card interface 321 is preferably designed to be slightly larger than the outer diameter of the first card post 71. When the first card post 71 is downwardly engaged with the card interface 321, the two can move relative to each other, thereby allowing a certain amount of movement space between the auxiliary plate 3 and the guide rod 6. The movement of the first card post 71 in the card interface 321 can offset the impact of the auxiliary plate 3, thereby improving the stability of the auxiliary plate 3. When the auxiliary plate 3 moves upward, it will support the connecting arm 7 via the second lifting connector 32, thereby driving the connecting arm 7 to move along the guide rod 6.

[0057] Optimally, the connecting arm 7 is provided with an inclined branch arm 72 ; one end of the inclined branch arm 72 extends obliquely to above or below the auxiliary plate 3 , and a buffer pad 73 is provided in the area of ​​the auxiliary plate 3 .

[0058] The oblique arm 72 is a branch of the connecting arm 7, which can extend above or below the auxiliary plate 3. When the auxiliary plate 3 supports the equipment, or when the equipment is suspended from below the auxiliary plate 3 by the auxiliary lifting rope 4, the oblique arm 72 can contact or approach the equipment. The oblique arm 72 is equipped with a cushion 73 near the equipment to support the equipment during swinging, limiting the swing angle. At the same time, the cushion 73 of the oblique arm 72 can also contact the side wall of the equipment to maintain a stable angle during suspension.

[0059] Optimally, the inclined arm 72 is detachably engaged with the T-slot 74 of the connecting arm 7 via a T-block 721 .

[0060] The connecting arm 7 can be provided with a T-slot 74 at the top and / or bottom, and the inclined branch arm 72 is clamped to the T-slot 74 through a T-block 721, so that the inclined branch arm 72 can be detachably installed on the connecting arm 7. The inclined branch arm 72 can be installed as needed, and has high flexibility in use.

[0061] Optimally, it further includes: a guide seat 8;

[0062] The guide seat 8 is sleeved on the guide rod 6 and moves along the length direction of the guide rod 6; the guide seat 8 is provided with a horizontally oriented matching opening 81, and one end of the connecting arm 7 is provided with a second clamping column 75; the second clamping column 75 is horizontally clamped in the matching opening 81, so that one end of the connecting arm 7 can be detachably connected to the guide rod 6.

[0063] Guide base 8 is mounted on guide rod 6 and can be connected to auxiliary plate 3 via connecting arm 7 only when needed. The connecting arm 7 is simply connected to guide base 8, requiring only a second clamping post 75 to pass horizontally through mating opening 81. When auxiliary plate 3 moves upward, connecting arm 7 is lifted by second lifting connector 32. Connecting arm 7 then drives guide base 8 along guide rod 6 via second clamping post 75, thereby achieving the lifting and lowering movement of auxiliary plate 3 along guide rod 6.

[0064] Optimally, the upper surface of the auxiliary plate 3 is a storage plane 33, and the first lifting connector 31 is provided with a first connection hole 311 in the storage plane 33; the first connection hole 311 is used to connect the steel wire rope 21 or the auxiliary lifting rope 4;

[0065] When the steel wire ropes 21 of the two electric hoists 2 are detachably connected to the second lifting connector 32 below, the object placement plane 33 is used to place the lifted object.

[0066] In this embodiment, the upper surface of the auxiliary plate 3 forms a planar storage surface 33. The first lifting connector 31 is a hole within this planar structure, meaning that the first lifting connector 31 does not protrude from the upper surface of the storage surface 33. This allows the storage surface 33 to be used to hold a single object. Specifically, equipment can be placed on the storage surface 33, and the two electric hoists 2 can directly lift the second lifting connectors 32 at each end of the auxiliary plate 3, thereby jointly lifting the equipment on the auxiliary plate 3 on the storage surface 33.

[0067] Optimally, the first connection holes 311 are arranged in pairs in the lower groove of the storage plane 33, and the first connection holes 311 are exposed at the lower groove and the lower surface of the auxiliary plate 3; the upper end of the first connection hole 311 is lower than the height position of the storage plane 33; one end of the auxiliary hanging rope 4 is provided with an auxiliary hook 41; the auxiliary hook 41 enters the lower groove from one of the first connection holes 311 from bottom to top, and is engaged with the other first connection hole 311, so that one end of the auxiliary hanging rope 4 can be detachably connected to the first lifting connector 31.

[0068] This solution also provides a lower groove on the surface of the storage plane 33, and the lower groove is provided with a pair of first connection holes 311. The first connection holes 311 pass through the auxiliary plate 3 from top to bottom. In this way, the auxiliary hook 41 at one end of the auxiliary lifting rope 4 can enter the first connection hole 311 from bottom to top and be engaged with the other first connection hole 311 in the lower groove, so that the auxiliary lifting rope 4 can be detachably connected to the first lifting connector 31. In this way, based on the fact that the storage plane 33 can support the hoisted object, this solution can also lift another hoisting object under the auxiliary plate 3 through the auxiliary lifting rope 4, achieving the effect of a double lifting device, which can reduce the number of transfers for small and medium-sized equipment in the workshop. The double electric hoist 2 can provide sufficient supporting force, and the second lifting connector 32 can provide sufficient balance.

[0069] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
