Description

Technical Field

[0001] The invention relates to a closed busbar transportation device, belonging to the technical field of transportation. Background Art

[0002] The enclosed busbar is mainly composed of three parts: busbar conductor, supporting insulator and protective shielding shell. Both the conductor and the shell are made of aluminum tube structure. When installing the busbar in the enclosed busbar renovation of the original power station, the enclosed busbar needs to be transported from the generator layer to the busbar room and installed at a height of 2.5m. Due to too many people, it is difficult to be neat, and there is a certain safety risk when lifting it high. In addition, the installation time is long, and the renovation process is delayed.

[0003] In addition, the closed busbar will pass through a door during transportation, and the width of the door is small, which limits the height, width and length during transportation. In addition, power stations generally do not purchase special transportation tools for closed busbars because they are rarely used and cost-effective. They are usually modified from waste parts.

[0004] Therefore, a closed busbar transport tool that can transform scrap parts into those used in power stations is needed. Summary of the invention

[0005] The object of the present invention is to provide a closed busbar transport device to solve the problem in the above background technology that a closed busbar transport tool that can transform waste parts into a used in a power station is needed.

[0006] The technical solution of the present invention is as follows:

[0007] A closed busbar transport device, comprising:

[0008] A hydraulic forklift, wherein a fixing frame is installed on the hydraulic forklift;

[0009] A movable frame, the movable frame comprising two sets of base frames, moving wheels installed at the bottom of the base frames, and two sets of cross beams installed at the top of the base frames;

[0010] The distance between the two groups of beams is greater than the length of the fixing frame.

[0011] Preferably, there are two groups of base frames, and the two groups of base frames are connected by a telescopic frame.

[0012] Preferably, the fixing frame includes two sets of flip support frames, and the support frames include vertical beams, hinged seats that slide vertically on the vertical beams, and cross frames that are hingedly matched with the hinged seats.

[0013] Preferably, a limiting protrusion is provided on the top of the vertical beam, and a limiting groove is provided on one side of the cross frame; when the limiting protrusion is inserted into the limiting groove, the cross frame is horizontally fixed on the top of the vertical beam.

[0014] Preferably, a clamping device is installed on the crossbeam.

[0015] Preferably, the clamping device comprises a rotating shaft and a V-shaped clamping member sleeved on the outer wall of the rotating shaft.

[0016] Preferably, the clamping device further comprises a slide seat, the slide seat is slidably fitted on the cross beam, a clamping handle is mounted on the slide seat, and the V-shaped clamping member is rotatably connected to the slide seat via a rotating shaft.

[0017] Preferably, a torsion spring is sleeved on the outer wall of the rotating shaft.

[0018] Preferably, elastic parts are provided at both ends of the V-shaped clamp.

[0019] Preferably, a limiting portion is provided on the slide seat, and the limiting portion is used to limit the rotation range of the V-shaped clamping member.

[0020] The present invention has the following beneficial effects:

[0021] Existing scrap parts can be used for transformation. A fixed frame can be installed on the hydraulic forklift. The movable frame transfers the closed busbar to the fixed frame on the hydraulic trolley through the moving wheels. The closed busbar on the fixed frame is lifted up by the hydraulic forklift, which improves work efficiency.

[0022] Since hydraulic forklifts are large in size and heavy in weight, making them inconvenient to move, smaller and lighter mobile racks are used to transport the closed busbars, which can easily pass through doors with height, width and length restrictions.

[0023] The movable frame can be reduced in size for easy storage when not in use, and the fixed frame has a flippable structure that helps the hydraulic forklift pass through doors with height, width and length restrictions. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Embodiment 1:

[0033] like Figure 1 As shown:

[0034] There is a fire door with a width of 0.75 meters and a height of 1.95 meters on the busbar transportation road of the power station. Each section of the closed busbar is 2.9 meters long, 0.34 meters wide and 0.21 meters high. The installation position is limited by 1.5-meter interval supports and the space is small. During transportation, there are height, width and length restrictions, so we considered using steel pipes and angle irons to make a movable frame 3 with a width of 0.6m, a length of 1.4m and a height of 1.6m. Then, using a hydraulic forklift 1 that can lift 1.5m, we welded a fixed frame 2 with a height of 1.1m, a length of 1.2m and a width of 0.35m, and made special tools that can lift 2.6m. The length and width of the movable frame 3 and the fixed frame 2 match to ensure that the overall structure of the movable frame 3 and the fixed frame 2 can withstand the weight of the closed busbar. The movable frame 3 and the fixed frame 2 are used together to move the movable frame 3 to the position to be lifted. There is no need to transfer the closed busbar to the fixed frame 2. During the rising process of the hydraulic forklift 1, the closed busbar on the movable frame 3 is directly lifted upward through the fixed frame 2, thereby realizing the handling work.

[0035] The movable frame 3 includes a base frame 31, a moving wheel 4 installed at the bottom of the base frame 31, and two groups of beams 32 installed at the top of the base frame 31. The spacing between the two groups of beams 32 is greater than the length of the fixed frame 2, so that the fixed frame 2 can be relatively moved between the two groups of beams 32; then the hydraulic forklift 1 drives the fixed frame 2 to lift and can lift the closed busbar located on the two groups of beams 32 upward.

[0036] Embodiment 2: Improved on the basis of embodiment 1:

[0037] like Figure 1-3 As shown:

[0038] Due to the long length of the fixing frame 2, it is impossible to pass through some narrow doors;

[0039] Therefore, the fixing frame 2 is improved, and the fixing frame 2 includes two groups of symmetrically arranged flip support frames 21; the flip support frame 21 includes a vertical beam 211, a hinge seat 212, and a cross frame 213. The vertical beam 211 is vertically fixed on the hydraulic forklift 1, the hinge seat 212 slides vertically and linearly on the vertical beam 211, and the cross frame 213 is hingedly matched with the hinge seat 212; a limiting convex point 214 is provided on the top of the vertical beam 211, and a limiting groove 215 is provided at the bottom of the cross frame 213;

[0040] like Figure 2 As shown, the horizontal frame 213 rotates to a horizontal state, and the limiting protrusion 214 is relatively inserted into the limiting groove 215. At this time, the horizontal frame 213 is fixed relative to the vertical beam 211, and the horizontal frame 213 is used to carry the closed busbar;

[0041] like Figure 3 As shown, the hinge seat 212 moves upward so that the limiting groove 215 of the horizontal frame 213 is separated from the limiting protrusion, and then the horizontal frame 213 rotates to a vertical state, thereby shortening the length of the fixing frame 2 and facilitating passing through a narrow door.

[0042] Embodiment 3: Improved on the basis of Embodiment 1 or 2:

[0043] like Figure 4 As shown, there are two groups of base frames 31, and two groups of cross beams 32 are respectively located on different base frames 31. A movable wheel 4 is installed at the bottom of each group of base frames 31. The two groups of base frames 31 are connected by a telescopic frame 33, so that the distance between the two groups of base frames 31 can be adjusted. The telescopic frame 33 can adopt an "X"-shaped structure; thereby, the size of the adjustable fixed frame 3 is convenient for storage when not in use.

[0044] Embodiment 4: Improved on the basis of embodiment 3:

[0045] like Figure 5 As shown, two sets of symmetrical clamping devices 5 are installed on each set of cross beams 32, and the clamping devices 5 include a slide seat 51, a clamping handle 52, a V-shaped clamping member 53, a rotating shaft 531, an elastic part 54 and a torsion spring (not shown in the drawings);

[0046] The slide 51 slides horizontally and linearly on the cross beam 32, and the clamping handle 52 is installed on the slide 51 to fix the slide 51 at a set position of the cross beam 32, so that the distance between the two sets of clamping devices 5 can be adjusted to adapt to closed busbars of different widths;

[0047] The middle part of the V-shaped clamp 53 is rotatably connected to the slide 51 through a rotating shaft 531, and a torsion spring is sleeved on the outer wall of the rotating shaft 531. Two sets of limiting parts are provided on the slide 51, and the rotation angles of the two sets of V-shaped clamps 53 are limited by the two sets of limiting parts. Assuming that the cross beam 32 is 0°, the lateral ends of the V-shaped clamp 53 rotate within the range of (-15°)-(+15°), and the torsion spring drives the V-shaped clamp 53 to reset; both ends of the V-shaped clamp 53 are provided with elastic parts 54, and the elastic parts 54 can be made of rubber with a certain elastic deformation ability. The lateral ends and vertical ends of the V-shaped clamp 53 are abutted against the closed busbar through the elastic parts 54;

[0048] like Figure 5 As shown, it is the normal state when the V-shaped clamping member 53 is not working. At this time, the lateral end of the V-shaped clamping member 53 is slightly higher than the crossbeam 32. When the closed busbar is placed on the crossbeam 32, the bottom wall of the closed busbar abuts against the lateral end of the V-shaped clamping member 53 to push the V-shaped clamping member 53 to rotate. During this process, the torsion spring generates a reverse elastic force, and the vertical end of the V-shaped clamping member 53 rotates and abuts against the side wall of the closed busbar, thereby realizing automatic clamping of the closed busbar.

[0049] Both ends of the V-shaped clamp 53 abut against the closed busbar through the elastic part 54, and the elastic part 54 can be deformed and adaptively adjusted within a certain range;

[0050] When the fixing frame 2 moves relatively to between the two sets of cross beams 32 and is located directly below the closed busbar, the hydraulic forklift 1 drives the fixing frame 2 to rise. During this process, the fixing frame 2 abuts against the closed busbar directly above, thereby driving the closed busbar to follow the rise; at the same time, under the elastic force of the torsion spring, the V-shaped clamping frame 53 rotates in the opposite direction and resets, so that the vertical end of the V-shaped clamping frame 53 is separated from the side wall of the closed busbar, so that the vertical end of the V-shaped clamping frame 53 automatically releases the closed busbar.

[0051] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
