Description

A chassis support platform for a garbage collection vehicle Technical Field

[0001] This utility model relates to the field of garbage collection vehicle manufacturing technology, and in particular to a chassis bracket welding support platform for a garbage collection vehicle. Background Technology

[0002] A garbage collection truck is a specialized vehicle used for collecting and transporting garbage. It mainly consists of a chassis, garbage bin, electrical system, and wheels. The chassis support is part of the chassis, and its structure is shown in Figure 1. This chassis support includes a first chassis side beam 100, a second chassis side beam 200, a first chassis crossbeam 300, a front end baffle 400, a second chassis crossbeam 500, a third chassis crossbeam 600, a first chassis crossbeam connecting beam 700, a second chassis crossbeam connecting beam 800, and a bottom sub-steel plate mounting frame 900. All of these components are independent parts and are not located on the same plane after welding. The traditional chassis support welding method is as follows: The first chassis side beam 100, the second chassis side beam 200, and the first crossbeam 300 are laid flat and welded together. Then, the front end baffle 400 is welded to the front ends of the first chassis side beam 100 and the second chassis side beam 200. Next, the second chassis crossbeam 500, the third chassis crossbeam 600, the first chassis crossbeam connecting beam 700, the second chassis crossbeam connecting beam 800, and the bottom sub-steel plate mounting bracket 900 are welded together. However, the above method has the following problems: First, if the distance between the first chassis side beam 100 and the second chassis side beam 200 is not easy to control, that is, after welding with the first crossbeam 300 and the front end baffle 400, the second chassis crossbeam 500 and the third chassis crossbeam 600 may not be able to fit in or have a width that prevents welding. At the same time, the first chassis crossbeam connecting beam 700 and the second chassis crossbeam connecting beam 800 have the same problem. Secondly, after the first chassis side beam 100, the second chassis side beam 200, the first crossbeam 300, and the front baffle 400 are welded, positioning the second chassis crossbeam 500 and the third chassis crossbeam 600 is difficult. Similarly, positioning the bottom sub-steel plate mounting frame 900 is also very difficult.

[0041] Specifically, the chassis support platform of the garbage collection vehicle includes a rectangular lower support frame 1, a first transverse support frame 2 and a second transverse support frame 3 fixed on the rectangular lower support frame 1, a lower support rectangular frame 4 fixed on the first transverse support frame 2 and the second transverse support frame 3, columns 5 correspondingly arranged on both sides of the rear end of the lower support rectangular frame 4, a first crossbeam 6 and a second crossbeam 7 arranged inside the lower support rectangular frame 4, a first crossbeam connecting beam 8 and a second crossbeam connecting beam 9 arranged between the first crossbeam 6 and the second crossbeam 7, a T-shaped support seat 11 arranged on the first crossbeam 6, a side support rod 12 arranged on the front side of the lower support rectangular frame 4, transverse support seats 10 respectively arranged at the ends of the first crossbeam 6 and the second crossbeam 7, several clamping assemblies 13 arranged around the lower support rectangular frame 4, on the first crossbeam connecting beam 8, the second crossbeam connecting beam 9 and the transverse support seats 10, and a bottom sub-steel plate mounting frame positioning mechanism 14 and a bottom sub-steel plate mounting frame clamping assembly 15 arranged on the lower support rectangular frame 4. The clamping assembly 13 clamps the first chassis side beam 100, the second chassis side beam 200, the first chassis crossbeam 300, the front end baffle 400, the second chassis crossbeam 500, the third chassis crossbeam 600, the first chassis crossbeam connecting beam 700, and the second chassis crossbeam connecting beam 800. Additionally, the bottom sub-steel plate mounting bracket positioning mechanism 14 contacts the outer edge and end of the bottom sub-steel plate mounting bracket 900. Finally, the bottom sub-steel plate mounting bracket clamping assembly 15 presses against the top of the bottom sub-steel plate mounting bracket 900.

[0042] In this embodiment, the clamping assembly 13 includes a first L-plate 131 and a second L-plate 132 with identical structures. An L-shaped clamping plate 133 is rotatably disposed between the first L-plate 131 and the second L-plate 132, forming a U-shape together with the first L-plate 131 and the second L-plate 132. A rotating support shaft 134 passes through the first L-plate 131, the L-shaped clamping plate 133, and the second L-plate 132. A front limiting rod 135 passes through the first L-plate 131 and the second L-plate 132 and is located at the lower front end of the L-shaped clamping plate 133. A rear limiting rod 136 passes through the first L-plate 131 and the second L-plate 132 and is located at the lower rear end of the L-shaped clamping plate 133. The rotating support shaft 134 passes through the lower front end of the L-shaped clamping plate 133. Additionally, several support shafts 137 are provided on the first L-plate 131 and the second L-plate 132, and these support shafts 137 pass through the first L-plate 131 and the second L-plate 132. A support column 1371 is provided on the support shaft 137, positioned between the first L-plate 131 and the second L-plate 132, and the length of the support column 1371 is greater than or equal to the thickness of the L-shaped clamping plate 133. In this embodiment, when no material is placed, the front end of the L-shaped clamping plate 133 is raised, and its rear end extends outward, as shown in Figure 10. When material is placed, the material presses down on the front end of the L-shaped clamping plate 133, causing the rear end of the L-shaped clamping plate 133 to approach the material and, together with the first L-plate 131 and the second L-plate 132, form a U-shape to clamp the material, as shown in Figure 11. The clamping assembly 13 in this embodiment uses a downward clamping method, which makes the placement and removal of the chassis support efficient and reliable.

[0043] In this embodiment, the bottom sub-steel plate mounting frame 900 is positioned using the bottom sub-steel plate mounting frame positioning mechanism 14. This positioning mechanism 14 includes two pivot seats 141 fixed to the lower support rectangular frame 4, and a rotation positioning mechanism 142 rotatably sleeved within the pivot seats 141. The rotation positioning mechanism 142 includes a rotating shaft 1423 with its ends respectively sleeved within the pivot seats 141, an extension rod 1422 mounted on the rotating shaft 1423, and an L-shaped positioning frame 1421 mounted on the top of the extension rod 1422. By rotating the extension rod 1422 and the L-shaped positioning frame 1421, and placing the bottom sub-steel plate mounting frame 900 on the first chassis side beam 100 and the second chassis side beam 200, positioning is achieved by the inner side of the L-shaped positioning frame 1421 contacting the outer side and end of the bottom sub-steel plate mounting frame 900.

[0044] After the bottom sub-steel plate mounting frame 900 is positioned, it can be clamped using the bottom sub-steel plate mounting frame clamping assembly 15. The bottom sub-steel plate mounting frame clamping assembly 15 includes a lower mounting beam 151 fixedly connected to the inner side of the lower support rectangular frame 4, a clamping column 152 fixed on the lower mounting beam 151, a switching clamp located at the top of the clamping column 152, an arc-shaped clamping plate 157 located on the switching clamp, and a compression support column 158 located inside the arc-shaped clamping plate 157. The arc-shaped clamping plate 157 is used to press against the top of the bottom sub-steel plate mounting frame 900.

[0045] In this embodiment, the switching fixture includes a fixture base 153 fixed to a fixture column 152, a switching handle 154 whose lower part is axially connected to the front end of the fixture base 153, a fixture rod 156 whose rear end is axially connected to the upper rear end of the fixture column 152, and a first crank arm 155 disposed between the switching handle 154 and the fixture rod 156. An arc-shaped clamping plate 157 is disposed at the lower front end of the fixture rod 156.

[0046] The following is a brief description of the usage process of this embodiment:

[0047] First, the front baffle 400 is inserted into the clamping assembly 13 at the rear end of the lower support rectangular frame 4 and held in place by the clamping assembly 13. Since the front baffle 400 is relatively high, it is supported by the column 5 to prevent it from tipping over. Next, the first chassis side beam 100 and the second chassis side beam 200 are placed in, with their rear ends pressing against the front baffle 400. Similarly, the first chassis side beam 100 and the second chassis side beam 200 are held in place by the clamping assembly 13 on the side of the lower support rectangular frame 4. Then, the first chassis crossbeam 300, the second chassis crossbeam 500, the third chassis crossbeam 600, the first chassis crossbeam connecting beam 700, and the second chassis crossbeam connecting beam 800 are placed in, all held in place by the clamping assembly 13. Finally, flip the bottom sub-steel plate mounting bracket positioning mechanism 14 upwards, and the bottom sub-steel plate mounting bracket 900 can be placed in it. Then, use the bottom sub-steel plate mounting bracket clamping assembly 15 to clamp it to complete the clamping work, and then the subsequent welding work can be carried out.

[0048] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any changes made based on the design principles of this utility model, or any non-creative changes made on this basis, shall fall within the scope of protection of this utility model.
