Description

Technical Field

[0001] This utility model belongs to the technical field of bus manufacturing equipment, specifically relating to a bus gantry rack. Background Technology

[0002] Different car models require material crates of different sizes. Due to the special nature of the door assembly, the storage device needs to be fixed to the door frame and bottom at the top and bottom because its side is the outer panel of the door, and it cannot collide with the door or the material crate, so as to ensure the relative stability of the door.

[0003] Currently, the door assembly of a manufactured bus mainly consists of foldable small doors and large doors. Both small and large doors have rotating pillars on the upper left side, and the lower left side of the small door extends a predetermined length beyond the large door to connect to the bus frame. This results in inconsistent overall door heights, and the dimensions of the door assemblies also vary between different models. Existing door assembly storage devices are developed for individual bus models, meaning the upper and lower limit distances are fixed, and they are designed for door assemblies with flat tops and bottoms. This is especially problematic for models discontinued in China; existing storage crates cannot be used to store door assemblies for these models. Utility Model Content

[0004] The purpose of this utility model is to provide a bus door frame storage rack for storing unevenly shaped door assemblies, preventing collision damage between doors and ensuring relative stability of the doors.

[0005] The technical solution adopted by this utility model is a bus gantry placement frame, including a rectangular bottom frame. The bottom frame has universal wheels with built-in brakes at the four lower corners. Two front telescopic uprights and a rear telescopic upright are respectively provided at the four corners of the bottom frame. A load-bearing frame is provided at the bottom of the front telescopic uprights and the rear telescopic uprights. The load-bearing frame is spaced apart from the bottom frame and has multiple fixed brackets for supporting the large doors of the bus gantry. The top of the front telescopic uprights and the rear telescopic uprights are provided with a top left longitudinal beam and a top right longitudinal beam.

[0009] Preferably, the front crossbar and the rear crossbar are respectively provided with grooves at intervals, and the two ends of the first fixed longitudinal beam and the second fixed longitudinal beam are embedded into the front crossbar or the rear crossbar through the grooves.

[0010] Preferably, the bottom frame includes a bottom front crossbeam and a bottom rear crossbeam arranged in parallel. The lower ends of the bottom front crossbeam and the bottom rear crossbeam are respectively fixedly connected to the bottom left longitudinal beam and the bottom right longitudinal beam. The front telescopic upright and the rear telescopic upright are fixed to the outer end face of the bottom left longitudinal beam or the bottom right longitudinal beam.

[0018] The present invention will be further explained below with reference to the accompanying drawings to enable those skilled in the art to better understand it.

[0019] Example 1

[0020] like Figure 1-5 As shown, a door assembly storage device includes a bottom frame 1. Two front telescopic uprights 2 and a rear telescopic upright 3 are respectively provided at the four corners of the bottom frame 1. The bottom frame 1 includes a bottom front crossbeam 101 and a bottom rear crossbeam 102 arranged in parallel. The lower ends of the bottom front crossbeam 101 and the bottom rear crossbeam 102 are respectively fixedly connected to the bottom left longitudinal beam 103 and the bottom right longitudinal beam 104. The front telescopic uprights 2 and the rear telescopic uprights 3 are fixed to the outer end face of the bottom left longitudinal beam 103 or the bottom right longitudinal beam 104, which has a large connection area. The overall bottom center of gravity of the door assembly storage device is close to the ground, and the stability is good.

[0021] The front telescopic upright 2 and the rear telescopic upright 3 are equipped with a load-bearing frame at their lower parts. The load-bearing frame is spaced apart from the bottom frame 1 and has multiple fixed brackets on it to support the large door of the bus gantry. Specifically, the load-bearing frame includes a first fixed longitudinal beam 6 and a second fixed longitudinal beam 7 arranged parallel to each other between the front crossbar 4 and the rear crossbar 5. Multiple first fixed brackets 8 and second fixed brackets 9 are arranged at intervals along the length of the first fixed longitudinal beam 6 and the second fixed longitudinal beam 7, respectively. The first fixed longitudinal beam 6 and the second fixed longitudinal beam 7 provide support for the large door of the door assembly. The top of the front telescopic upright 2 and the rear telescopic upright 3 are respectively provided with a top front crossbar 13 and a top rear crossbar 14. The upper parts of the top front crossbar 13 and the top rear crossbar 14 are respectively provided with a top left longitudinal beam 15 and a top right longitudinal beam 16. Threaded holes are opened at intervals along the length of the top left longitudinal beam 15, and bolts are used to fix the rotating column of the small door of the door assembly through the threaded holes. The first fixed longitudinal beam 6 and the second fixed longitudinal beam 7 are used to support the large door of the door assembly. At the same time, the first fixed bracket 8 and the second fixed bracket 9 are used to fasten the first fixed longitudinal beam 6 and the second fixed longitudinal beam 7 to the lower part of the large door. The upper left longitudinal beam 15 is connected to the rotating column of the small door to fix the entire door assembly, prevent collision damage between the doors, and ensure stable storage of the doors.

[0022] To further improve the stability of the door assembly placement, a third fixed longitudinal beam 10 and a fourth fixed longitudinal beam 11 are respectively provided above both ends of the bottom front crossbeam 101 and the bottom rear crossbeam 102. A third fixed bracket 12 is provided on the third fixed longitudinal beam 10. The bottom left end of the small door assembly is connected to the third fixed longitudinal beam 10 through the third fixed bracket 12, and the bottom of the large door assembly is connected to the first fixed longitudinal beam 6 through the first fixed bracket 8 and to the second fixed longitudinal beam 7 through the second fixed bracket 9. Using the third fixed longitudinal beam 10 as the left-end positioning standard for storing the door assembly, and folding the door assembly for storage after positioning by the third fixed longitudinal beam 10, facilitates the sequential placement of multiple door assemblies while effectively saving storage space.

[0023] Furthermore, both the front telescopic upright 2 and the rear telescopic upright 3 are slidably fitted with fixing sleeves 17. Threaded holes are opened on opposite sides of the fixing sleeves 17. After tightening with fastening bolts 18 through the threaded holes, the inner end of the fixing sleeve 17 abuts against the front telescopic upright 2 or the rear telescopic upright 3, fixing the fixing sleeve 17 to the front telescopic upright 2 or the rear telescopic upright 3. The two ends of the front crossbar 4 overlap the fixing sleeves 17 of the two front telescopic uprights 2, and the rear crossbar 5 overlaps the fixing sleeves 17 of the two rear telescopic uprights 3. By changing the height of the fixing sleeves 17, the height of the front crossbar 4 and the rear crossbar 5 can be adjusted, that is, the height of the first fixed longitudinal beam 6 and the second fixed longitudinal beam 7 can be adjusted. In addition, the front crossbar 4 and the rear crossbar 5 are respectively provided with grooves 19 spaced apart. The two ends of the first fixed longitudinal beam 6 and the second fixed longitudinal beam 7 are embedded into the front crossbar 4 or the rear crossbar 5 through the grooves 19. By changing the connection positions of the first fixed longitudinal beam 6 and the second fixed longitudinal beam 7 with the front crossbar 4 and the rear crossbar 5, and adjusting the distance between the first fixed longitudinal beam 6 and the second fixed longitudinal beam 7, it is possible to accommodate the storage of different sizes of this type of door assembly. In addition, by adjusting the front crossbar 4 and the rear crossbar 5 so that the first fixed longitudinal beam 6 and the second fixed longitudinal beam 7 and the third fixed longitudinal beam 10 and the fourth fixed longitudinal beam 11 are at the same height, it is possible to store most existing flat door assemblies, thereby improving versatility and saving resources.

[0024] 1) The first fixed bracket 8 includes an L-shaped first bracket plate 801. The bottom plate of the first bracket plate 801 has fixing holes, which are used to connect it to the first fixed longitudinal beam 6 via screws. The side plate of the first bracket plate 801 is trapezoidal, and a first connecting hole 802 is provided in the center of the first bracket plate 801. The first connecting hole 802 is strip-shaped, with the upper diameter larger than the lower diameter. Screws are used to connect it to the bottom of the large door of the door assembly via the first connecting hole 802. The second fixed bracket 9 includes an L-shaped second bracket plate 901. The bottom plate of the second bracket plate 901 has fixing holes near both ends, which are used to connect it to the second fixed longitudinal beam 7 via screws. The side plate of the second bracket plate 901 has a second connecting hole 902, which is strip-shaped with the lower diameter larger than the upper diameter. Screws are used to connect it to the large door of the door assembly via the second connecting hole 902. The third fixing bracket 12 includes a fastening plate 1201 and a connecting plate 1202. The connecting plate 1202 is L-shaped, and fixing holes are respectively opened at both ends of the connecting plate 1202. Screws are used to fix the third fixing bracket 12 to the third fixing longitudinal beam 10 through the fixing holes. The fastening plate 1201 is located at the bend of the connecting plate 1202 and is perpendicular to the connecting plate 1202. At least two third connecting holes 1203 are vertically opened on the fastening plate 1201. Screws are used to connect the small door of the door assembly through the third connecting holes 1203. In use, the first fixing bracket 8, the second fixing bracket 9, and the third fixing bracket 12 can change direction according to the folding degree of the door assembly to ensure that they are always parallel and close to the door panel of the door assembly, improving the connection reliability and avoiding stress damage caused by inconsistent force directions. In addition, the design of the third connecting holes of the first and second connecting holes has a margin, which is conducive to the screws fully connecting to the lower part of the door assembly.

[0025] To facilitate the turnover and use of the door assembly, the bottom frame 1 is equipped with casters 20 at the four lower corners, and the casters 20 are equipped with brakes.

[0026] How to use:

[0027] Step 1: Lift a door assembly into the storage device, located at the rear of the bottom frame, and align it vertically so that the bottom left end of the small door of the door assembly rests against the third fixed longitudinal beam;

[0028] Step 2: Adjust the height of the fixing sleeve so that the first fixing longitudinal beam and the second fixing longitudinal beam are located at the lower part of the large door of the door assembly and close to it. According to the model of the door assembly, change the position of the first fixing longitudinal beam and the second fixing longitudinal beam and adjust the distance between them.

[0029] Step 3: Fold the small door and the large door of the folding door assembly. The door assembly retracts. The left end of the small door of the door assembly is aligned with the third fixed bracket. The large door of the door assembly is located on the first fixed longitudinal beam and the second fixed longitudinal beam. Further adjust the folding degree of the door assembly so that the two ends of the large door are close to the first fixed bracket and the second fixed bracket respectively.

[0030] Step 4: Lower the front and rear telescopic uprights until the top left longitudinal beam abuts against the top of the rotating pillar of the small door assembly.

[0031] Step 5: Adjust the angle of the third fixing bracket so that the connecting plate is parallel to and close to the small door of the door assembly. The mounting hole at the bottom left end of the small door corresponds to the third connecting hole of the third fixing bracket. Use bolts to initially connect the third fixing bracket and the third fixing longitudinal beam through the fixing holes, but do not tighten them. Adjust the mounting positions at both ends of the bottom of the large door of the door assembly to align with the connecting holes of the first fixing bracket and the second fixing bracket, and tighten them with bolts. Then tighten the bolts on the fixing holes of the third fixing bracket, and use bolts to tighten the third bracket plate and the small door through the first connecting hole.

[0032] Step 6: Raise the front and rear telescopic poles upwards by 2-3cm, and use screws to connect them to the top left longitudinal beam through the installation position at the top of the rotating column. At this time, there is a gap between the top of the rotating column and the top left longitudinal beam.

[0033] Step 7: Move the second door assembly into the device and position it in front of the first door assembly. Align it vertically so that the bottom left end of the small door of the door assembly rests against the third fixed longitudinal beam. Then, follow steps 3 and 5. Finally, use a screw to connect it to the top left longitudinal beam through the installation position at the top of the rotating column. This completes the storage and fixing of the second door assembly. Subsequent door assemblies are placed sequentially from back to front according to the second door frame. When you need to retrieve a door assembly, simply loosen the connection between the door assembly and the storage device from front to back.

[0034] This method uses the first gantry assembly as a standard. First, the relative positions of the top left longitudinal beam, the first fixed longitudinal beam, and the second fixed longitudinal beam are adjusted according to the dimensions of the first gantry assembly. This allows the top left longitudinal beam and the bottom left longitudinal beam to support the small door between them. The first and second fixed longitudinal beams provide balanced support for the large door. After being securely connected by the first, second, and third fixed brackets, the basic shape of the bus gantry is determined. Then, the top left longitudinal beam is raised to create a gap between it and the rotating column of the small door. This satisfies the positioning and installation requirements while facilitating the subsequent placement of the bus gantry and its later disassembly and retrieval. The overall installation efficiency is high, and the usage effect is good.
