[0026] Example

[0027] Please refer to Figure 1-Figure 4The utility model provides an adjustable multi-purpose rail transit vehicle roof cover panel transport and storage trolley, including a bottom rectangular frame 1, a vertical rectangular frame 2, a rectangular tube 3, a branch pipe handrail 4, a bending groove 5, a universal wheel 6, and a lifting ear 7.

[0028] Furthermore, a connecting rectangular tube is horizontally mounted in the middle of the bottom rectangular frame 1 , a vertical rectangular frame 2 is vertically fixed on the bottom rectangular frame 1 , and the bottom of the frame of the vertical rectangular frame 2 is connected to the frame of the bottom rectangular frame 1 .

[0029] The bottom rectangular frame 1 and the vertical rectangular frame 2 form the main support structure of the trolley, and the connecting rectangular tubes ensure the load-bearing strength of the middle frame of the bottom rectangular frame 1.

[0030] Furthermore, the facade rectangular frame 2 includes two vertically arranged side frames, and multiple rectangular tubes 3 are symmetrically distributed on both sides of each side frame. The multiple rectangular tubes 3 are vertically arranged on the side frames of the facade rectangular frame 2. The rectangular tubes 3 are relatively slidably connected to the side frames of the facade rectangular frame 2. When the two rectangular tubes 3 at the same height on the two side frames are used together, long and large cover panels for subway vehicles can be supported for storage, and multiple vertically arranged rectangular tubes 3 can increase the number of cover panels that can be stored.

[0031] When cover panels of different heights are placed on the rectangular tube 3, the rectangular tube 3 can be vertically displaced on the vertical rectangular frame 2, changing the height space between the two rectangular tubes 3 for easy storage.

[0032] In addition, the transverse length of the rectangular tube 3 can also be adjusted telescopically, thereby being able to store cover panels of different sizes.

[0033] In this embodiment, the rectangular tube member 3 includes a rectangular tube sleeve 31 , a lock hole plate 32 , a rectangular tube 33 , a stopper 34 , and a screw hole 35 .

[0034] Specifically, sliding grooves are vertically arranged on both sides of the side frames of the facade rectangular frame 2, one end of the rectangular tube sleeve 31 is slidably connected to the sliding groove, and a keyhole plate 32 is fixedly arranged on the rectangular tube sleeve 31. The keyhole plate 32 is located on both sides of the sliding groove of the facade rectangular frame 2 and fits with the side frames of the facade rectangular frame 2. There are threaded holes on the keyhole plate 32, and the holes are perpendicular to the side frames of the facade rectangular frame 2.

[0035] Preferably, when the height position of the rectangular tube member 3 needs to be adjusted, the rectangular tube sleeve 31 is driven to move to a specified height in the slide groove of the vertical rectangular frame 2, and then the bolts and gaskets are tightened on the threaded holes of the lock hole plate 32 so that the bottom of the bolt abuts against the frame of the vertical rectangular frame 2, exerting a lateral force on the rectangular tube sleeve 31.

[0036] Because the rectangular tube sleeve 31 is located at one end of the rectangular tube 33 in the slide groove, there is a matching block (not shown in the figure) between the rectangular tube sleeve 31 and the slide groove to prevent the rectangular tube sleeve 31 from escaping from the vertical direction of the slide groove. Therefore, the force applied to the rectangular tube sleeve 31 by the bolt locking will drive the block to move along the vertical direction of the slide groove, making it fit more closely with the slide groove, thereby increasing the friction resistance between the two, so that the rectangular tube sleeve 31 cannot slide due to resistance and is fixed.

[0037] Specifically, a rectangular tube 33 is slidably sleeved in the other end of the rectangular tube sleeve 31, and the sliding direction of the rectangular tube 33 is the length direction of the rectangular tube sleeve 31. A plurality of screw holes 35 are passed through the rectangular tube sleeve 31, and the screw holes 35 are arranged along the length direction of the rectangular tube sleeve 31. The channels of the screw holes 35 are perpendicular to the rectangular tube sleeve 31 and the rectangular tube 33.

[0038] Preferably, when the horizontal length of the rectangular tube 3 needs to be adjusted, the rectangular tube 33 is driven to slide and displace a specified length in the rectangular tube sleeve 31, and then the bolts and gaskets are tightened on the screw holes 35 in the rectangular tube sleeve 31 corresponding to the slid-out rectangular tube 33, so that the bottom of the bolt penetrates into the rectangular tube sleeve 31 and abuts against the rectangular tube 33, applying a vertical force between the rectangular tube 33 and the rectangular tube sleeve 31, increasing the friction resistance between the two, so that the rectangular tube 33 cannot slide due to the resistance and is fixed.

[0039] In addition, a stopper 34 is fixedly provided at the outermost end of the rectangular tube 33 in the length direction away from the rectangular tube sleeve 31. When the cover plate is placed on the rectangular tube 3, the stopper 34 at the outermost end of the rectangular tube 33 can buckle the outermost part of the cover plate, thereby increasing the stability of the cover plate when stored on the device and ensuring that the cover plate will not tip over or slip.

[0040] Furthermore, a handrail is provided at the middle height position of the vertical rectangular tube 33. The handrail is welded from multiple small steel pipes and is located on one side of the side frame of the vertical rectangular tube 33 to facilitate manual pushing of the device.

[0041] Pads are provided at the four corners of the bottom rectangular frame 1, and universal wheels 6 are fixedly provided at the bottom of the pads. When the device is pushed by manually holding the handrail, the device moves through the universal wheels 6 to transport the cover plate parts on the device.

[0042] Furthermore, two bending groove members 5 are fixedly provided on the bottom surface of the bottom rectangular frame 1, and the slots in the bending groove members 5 are matched and connected with the forks of an external forklift, so that the device and the cover plate members on the device can be transferred and transported by the forklift, and quickly pass through the bottom environment that the universal wheels 6 of the device cannot pass through.

[0043] The groove surfaces on both sides of the groove of the bending groove member 5 can limit the fork of the forklift to prevent the device from sliding toward the left and right sides of the fork during forklift transportation, causing the device to overturn.

[0044] Furthermore, two lifting ears 7 are fixedly provided on the top of the vertical rectangular frame 2. The lifting ears 7 are symmetrically distributed at both ends of the length direction of the top border of the vertical rectangular frame 2. The entire device and the cover panels on the device can be lifted and transported by external lifting facilities to transport the device to working environments at different heights.

[0045] In a specific embodiment, the bottom rectangular frame 1 is welded from rectangular tubes measuring 80x80x3mm. A 3mm thick rectangular tube 33 is used to ensure the structural strength of the device, and groove welding is used to ensure weld strength. The vertical rectangular frame 2 is also welded from rectangular tubes measuring 80x80x3mm, ensuring strength while providing sufficient space for installing the rectangular tube 3.

[0046] The rectangular frame of the bottom rectangular frame 1 is 1600mm long and 1560mm wide, ensuring storage space for long and large cover panels of subway vehicles; the rectangular frame of the vertical rectangular frame 2 is 1580mm high, thereby increasing the number of vertical installations of rectangular tubes 3, thereby increasing the number of long and large cover panels of subway vehicles that can be stored, and the height is suitable for ordinary people to place and remove.

[0047] The surfaces of the various components in the rectangular tube 3 are covered with polyurethane composite rubber sheets, which can prevent slipping and protect the cover plate from being scratched.

[0048] Thus far, various embodiments of the present invention have been described in detail. To avoid obscuring the concept of the present invention, some details known in the art have been omitted. Based on the above description, those skilled in the art will fully understand how to implement the technical solutions of the present invention. The scope of the present invention is defined by the appended claims.
