Abstract
Description
Technical Field
[0001] This utility model relates to the field of raw material storage for generator sets, specifically to a steel plate shelf for placing generator set chassis. Background Technology
[0002] To maintain the stability of the generator set's center of gravity, the generator set's chassis is usually made of steel. For large generator sets, the steel plates used can be as long as 6 meters and as wide as 1.5 meters. More than one plate is often needed when cutting the material, so how to safely move the plates from the storage area to the cutting area is a challenge.
[0003] In existing handling methods, vacuum suction cups can only transport one sheet at a time, and the sheets used for generator chassis are too long, causing excessive bending and deformation at both ends during suction and lifting, affecting subsequent use. In workshops, overhead cranes are often used to lift the sheets directly onto the pallets, with different sizes of sheets placed on different pallets. To save space, the pallets are usually stacked, requiring the upper pallets to be lowered first when lifting the lower ones, which is very inconvenient. Utility Model Content
[0004] In order to solve the problems in the prior art, this utility model provides a steel plate rack for placing generator set chassis that is suitable for overall loading and unloading by overhead cranes.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] A steel plate rack for placing generator set chassis includes a main frame, an outer frame, an inner pallet, and an outer pallet.
[0007] The main frame consists of a left frame and a right frame. Multiple fixed tracks are arranged at intervals along the vertical direction on the left and right frames, and each fixed track extends along the front and back direction.
[0008] Multiple outer pallets are spaced apart along the vertical direction, and the number corresponds to the number of fixed tracks; each outer pallet has movable tracks fixed at both ends, and the movable tracks are slidably connected to the corresponding fixed tracks.
[0009] The inner pallet is placed inside the corresponding outer pallet, and the side of the inner pallet is equipped with lifting lugs for overhead cranes;
[0010] Two external frames are provided and are respectively hinged to the front of the left and right frames. Multiple external rails are arranged at intervals along the vertical direction on the external frames, and the external rails correspond one-to-one with the fixed rails.
[0011] The external rail has two states: open and closed. When open, the external frame rotates to be flush with the left and right frames. At this time, the external rail on the external frame is collinear with the corresponding fixed rail, and the movable rail can slide out from the fixed rail onto the external rail. When closed, the external frame rotates to the front side of the main frame.
[0012] Preferably, the main frame also includes a rear frame for restricting the rearward movement of the outer pallet.
[0013] Preferably, the left frame, right frame and rear frame each include several longitudinal beams, which are reinforced and fixed together by diagonal beams; the fixed track is fixed to the inside of the longitudinal beams of the left and right frames.
[0014] Preferably, the external frame includes several longitudinal beams, and the longitudinal beams near the main frame are widened beams, which are hinged to the adjacent longitudinal beams on the main frame via hinges.
[0015] Preferably, the widening beam and the longitudinal beam are rectangular tubes. When the two are parallel to each other on the side adjacent to the hinge, it is the maximum unfolding angle of the external track. At this time, the external track and the fixed track are collinear.
[0016] Preferably, casters are installed at the lower end of the external frame.
[0017] Preferably, a gap is left between the rear end of the external track and the front end of the fixed track.
[0018] Preferably, the front end of the external track is provided with a limiting post.
[0019] Preferably, the outer tray is provided with a handle on the front side.
[0020] Preferably, ribs are provided at intervals below the outer tray.
[0021] The beneficial effects of this utility model are:
[0022] This utility model utilizes the cooperation between an openable external track and a fixed track. The external track can be collinearly connected with the fixed track, allowing the outer pallet to slide directly from the fixed track onto the external track. The uppermost inner pallet can be directly lifted away by an overhead crane. After the lower inner pallet slides onto the external track, it is unobstructed above and can then be transported to the unloading area by an overhead crane. After unloading is completed, the remaining materials are then hoisted back into the original outer pallet.
[0023] This utility model is easy to use and can meet the overall loading and unloading requirements of overhead cranes, ensuring that the plates are safely moved from the storage area to the unloading area. Attached Figure Description

[0032] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Detailed Implementation
[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0034] like Figures 1 to 8 As shown, this embodiment provides a steel plate rack for placing generator chassis, including a main frame, an outer frame, an inner pallet 2, and an outer pallet 1.
[0035] Specifically, the main frame consists of a left frame, a right frame, and a rear frame. Each of the left, right, and rear frames includes several longitudinal beams 11, which are reinforced and fixed together by diagonal beams 12. To improve the frame strength, a bottom beam 13 can also be added. The left and right frames are used to install and fix the rails, while the rear frame is used to restrict the rearward movement of the outer pallet.
[0036] Multiple fixed tracks 3 are arranged at intervals along the vertical direction on the inner side of the longitudinal beams 11 of the left and right frames, and each fixed track 3 extends along the front-back direction.
[0037] Multiple outer trays 1 are spaced apart along the vertical direction, and their number corresponds to the fixed rails 3. Each outer tray 1 has a movable rail 4 fixed at both its left and right ends. The movable rails 4 are slidably connected to the corresponding fixed rails 3, enabling the outer tray 1 to slide along the fixed rails 3.
[0038] Plates of the same specification are placed in the same inner pallet 2, and the inner pallet 2 is provided with lifting lugs 21 for overhead cranes on its side; the inner pallet 2 is placed in the corresponding outer pallet 1, and the outer pallet 1 is surrounded by the frame on both sides and the back.
[0039] During operation, the outer pallet 1 is always connected to the fixed rails 3 on both sides. The gantry crane can only lift the inner pallet 2. For easy pulling, a handle 10 is provided in the pulling direction of the outer pallet 1, which can be manually pulled by sliding action. Considering the large area of the board, ribs are installed at intervals under the outer pallet to support the middle of the outer pallet and prevent it from being suspended and deformed.
[0040] Two external frames are provided and are hinged to the front of the left and right frames respectively. The external frames can be opened and closed like a door. Multiple external tracks 5 are arranged at intervals along the vertical direction on the external frames, and the external tracks 5 correspond one-to-one with the fixed tracks 3.
[0041] The external track 5 has two states: open and closed. When it is open, the external frame rotates to be flush with the left and right frames. At this time, the external track 5 on the external frame is collinear with the corresponding fixed track 3, and the movable track 4 can slide out from the fixed track 3 onto the external track 5. When it is closed, the external frame rotates to the front side of the main frame, and the collinearity between the external track 5 and the fixed track 3 is released.
[0042] Specifically, the external frame includes two longitudinal beams, which are located on the front and rear sides of the external track 5, respectively. The longitudinal beam closer to the main frame is a widened beam 6, which is hinged to the adjacent longitudinal beam 11 on the main frame via a hinge 7.
[0043] In this embodiment, the widened beam 6 and the longitudinal beam 11 are rectangular tubes. When the two are parallel to each other on the side adjacent to the hinge, it is the maximum unfolding angle of the external track. At this time, the external track 5 and the fixed track 3 are collinear.
[0044] Casters 8 are installed at the lower ends of the two longitudinal beams of the external frame. With the cooperation of hinges 7 and casters 8, the external rail 5 can be folded and folded when not in use, saving space in the workshop. The casters 8 only bear the maximum force when the pallet slides onto the external rail 5. Under normal conditions, the force meets the usage requirements.
[0045] To prevent the external track 5 from interfering with the fixed track 3 when rotating, a gap is left between the external track 5 and the fixed track 3. The function of the widened beam 6 is to securely connect the external track 5 while leaving a gap to avoid interference. When the outer tray passes through the gap, it will briefly derail and then enter the external track 5 without affecting the overall sliding.
[0046] When the outer tray 1 moves backward, it is limited by the rear frame; the outer end of the outer track 5 is provided with a limiting post 9 to prevent the outer tray from falling off the track forward.
[0047] The working principle of this utility model is as follows:
[0048] During operation, the external frame is rotated to be flush with the left and right frames. At this time, the external rail 5 is adjusted to the open state, that is, the external rail 5 on the external frame is collinear with the corresponding fixed rail 3. The outer pallet 1 can slide directly from the fixed rail 3 onto the external rail 5. The uppermost inner pallet 2 can be directly lifted away by the gantry crane. After the lower inner pallet 2 slides onto the external rail, there is no obstruction above it. At this time, it can be transported to the unloading area by the gantry crane. After the unloading is completed, the remaining materials are hoisted into the original outer pallet.
[0049] When not in use, the external frame can be rotated to the front side of the main frame to fold and store, saving space in the workshop.
[0050] This utility model is easy to use and can meet the overall loading and unloading requirements of overhead cranes, ensuring that the plates are safely moved from the storage area to the unloading area.
