Specifically, the support platforms 200 are disposed on both sides of the cross beam 100 extending along the first direction a.

[0033] The cross beam 100 includes a plate beam 110 and a first reinforcing rib plate 120. The plate beam 110 includes a first plate body 111 and first bending portions 112 formed at opposite ends of the first plate body 111 along the first direction a. Specifically, the first plate body 111 has a bearing surface 1111. For the convenience of bearing, the first plate body 111 is also provided with a plurality of mounting through holes 1112 penetrating through itself along its thickness direction. The shape of the mounting through holes 1112 is not limited and can be any geometric figure, and there are a plurality of mounting through holes 1112 with different sizes among all the mounting through holes 1112, which can adapt to various loading assembly methods and improve the assembly flexibility.

[0034] A receiving space 113 is further formed between the first bending portion 112 and the first plate body 111, and the first reinforcing rib plate 120 is disposed in the receiving space 113. When specifically arranged, two ends of the first reinforcing rib plate 120 along the first direction a are respectively connected to the two first bending portions 112, the top end of the first reinforcing rib plate 120 is connected to the bottom of the first plate body 111, and the number of the first reinforcing rib plates 120 is multiple, and the multiple first reinforcing rib plates 120 are arranged at intervals. It should be noted that the first reinforcing rib plate 120 and the plate beam 110 are preferably welded in a bevel groove welding manner. The bevel groove butt welding method makes the weld transition smooth, can also avoid structural stress, improve the welding quality, and enhance the structural strength and stability. It should be emphasized that a first groove 121 is further formed on the side of the first reinforcing rib plate 120 facing away from the plate beam 110, and the groove wall of the first groove 121 is arc-shaped to disperse stress.

[0035] The support platform 200 includes a support frame 210 and a connection seat 220 disposed at the top end of the support frame 210, and the connection seat 220 is also detachably connected to the first bending portion 112.

[0037] In order to design the connecting seat 220 more conveniently, in a preferred embodiment, the connecting seat 220 includes a shock-absorbing backing plate 221 and a cover plate 222 connected to the shock-absorbing backing plate 221. Among them, the shock-absorbing backing plate 221 is preferably circular in structure, which is beneficial to the installation of the cab and improves the reliability of the vehicle. The cover plate 222 includes a second plate body 2221 and second bending portions 2222 formed at opposite ends of the second plate body 2221. When specifically arranged, the second plate body 2221 and the second bending portions 2222 on both sides form a U-shaped structure.

[0038] The bottom end of the second bending portion 2222 is arranged at the top end of the support frame 210, and the side wall of the second bending portion 2222 is detachably butted against the side wall of the first bending portion 112. In order to more conveniently realize the detachable connection between the second bending portion 2222 and the first bending portion 112, a first fastener passes through the first bending portion 112 and the second bending portion 2222 along the first direction a to detachably connect the first bending portion 112 and the second bending portion 2222 into one body. The first fastener can be a fastener such as a bolt or a screw. Through the above arrangement, the first fastener horizontally penetrates the first bending portion 112 and the second bending portion 2222, and the first fastener bears tension and compression, avoiding instability caused by shear force.

[0039] To strengthen the structural strength of the connecting seat 220, specifically, the connecting seat 220 further includes reinforcing side plates 223. The reinforcing side plates 223 are arranged between the two second bending portions 2222, and the top end of the reinforcing side plates 223 is also connected to the second plate body 2221. When specifically arranged, the number of the reinforcing side plates 223 is multiple, and the multiple reinforcing side plates 223 are arranged at intervals. Through the above arrangement, the bending resistance of the connecting seat 220 is increased, and the stiffness and strength of the structure are improved, thereby ensuring the reliable safety of the cab installed on the connecting seat 220. When specifically arranged, the shock-absorbing backing plate 221, the cover plate 222 and the reinforcing side plates 223 are all connected by welding, and the structure is firm and stable, capable of bearing a large load.

[0040] Combined Figure 4 as shown Figure 4The structural schematic diagram of the support platform 200 provided in the present application from another angle, in some embodiments, in order to design the support frame 210 more conveniently, a preferred embodiment, the support frame 210 includes a top plate 211 and a vertical plate 212 arranged on opposite sides of the top plate 211, the top plate 211 and the vertical plate 212 enclose a mounting cavity 213 for setting the second reinforcing plate rib 214, and the number of the second reinforcing plate rib 214 is multiple, and the multiple second reinforcing plate ribs 214 are arranged at intervals at the bottom of the top plate 211, and the side of the top plate 211 away from the vertical plate 212 is provided with a connecting seat 220. In the specific setting, the support frame 210 also includes a support plate 215, the support plate 215 is arranged between the two vertical plates 212, and the top of the support plate 215 is connected to the side of the top plate 211 away from the connecting seat 220 at a preset angle, and the preset angle is preferably 90°. Through the above setting, the bearing capacity of the top plate 211 is increased, and the rigidity and stability of the detachable front frame 10 are effectively improved.

[0041] In order to reduce the weight of the second reinforcing plate rib 214 without affecting the strength of the second reinforcing plate rib 214, a plurality of spaced first weight-reducing through holes 2141 are provided on the second reinforcing plate rib 214, and the first weight-reducing through holes 2141 penetrate the second reinforcing plate rib 214 along the thickness direction of the second reinforcing plate rib 214. In specific configuration, the shape of the first weight-reducing through holes 2141 is not limited, and can be any geometric shape, and the sizes of the first weight-reducing through holes 2141 are also different.

[0042] In order to reduce the weight of the support frame 210 and avoid fatigue damage caused by stress concentration, specifically, a first through hole 2121 is opened in the vertical plate 212 near the corner where the top plate 211 and the support plate 215 are connected. The first through hole 2121 penetrates the vertical plate 212 along the thickness direction of the vertical plate 212. In the specific setting, the first through hole 2121 is preferably a triangular structure, so that the support frame 210 is evenly stressed and stress concentration is avoided.

[0043] In order to enhance the rigidity and stability of the support frame 210, more specifically, the two top plates 211 have first ends 2111 facing each other, and a receiving space 217 for installing the third reinforcing plate rib 216 is formed between the first end 2111 and the support plate 215. In the specific setting, the number of the third reinforcing plate ribs 216 is multiple, and the multiple third reinforcing plate ribs 216 are arranged at intervals. Through the above setting, that is, in the direction in which the top plates 211 face each other, the top plate 211 protrudes from the lower side of the first end 2111 of the support plate 215 and the third reinforcing plate rib 216 is welded, thereby improving the bearing capacity of the top plate 211 and improving the structural rigidity and stability of the support frame 210. It is convenient to even out the bearing capacity and improve the strength and service life of the support frame 210.

[0044] To enhance the support stiffness of the support platform 200, more specifically, the two support plates 215 in the two relatively arranged support platforms 200 have first sides 2151 facing each other. The support platform 200 further includes a mounting base 230 provided on the first side 2151, and the mounting base 230 is detachably connected to the support plate 215. When specifically arranged, the mounting base 230 and the support plate 215 are preferably detachably connected by a second fastener, and the second fastener can be a fastener such as a bolt or a screw. Through the above arrangement, the connecting seat 220 and the mounting base 230 are respectively installed on the upper surface and the side surface of the support frame 210, avoiding the shear of the bolts on the side surface of the support frame 210 and reducing the risk of bolt instability on the side surface.

[0045] To more conveniently design the mounting base 230, further, the mounting base 230 includes a mounting base plate 231 and a mounting vertical plate 232 provided on the mounting base plate 231. The mounting vertical plate 232 is detachably connected to the support plate 215. Specifically, the mounting vertical plate 232 and the support plate 215 are detachably connected by a second fastener. When specifically arranged, the mounting vertical plate 232 has a first bevel edge 2321, and the first bevel edge 2321 is connected to the mounting base plate 231, and the two are preferably welded. Through the above arrangement, on the one hand, the weld is avoided from being sheared, and on the other hand, the structure of the mounting base 230 is simple and convenient for production.

[0046] To reduce the weight of the mounting base plate 231 while not affecting its strength, a second weight-reducing through hole 2311 is formed in the mounting base plate 231, and the second weight-reducing through hole 2311 penetrates the mounting base plate 231 along the thickness direction of the mounting base plate 231. When specifically arranged, the shape of the second weight-reducing through hole 2311 is not limited and can be any geometric shape, and the sizes of the second weight-reducing through holes 2311 are also different.

[0047] To strengthen the strength of the mounting base 230, the mounting base 230 further includes a plurality of mounting reinforcing ribs 233. The plurality of mounting reinforcing ribs 233 are parallel and spaced apart. The mounting reinforcing ribs 233 are preferably triangular structures, and the two adjacent sides of the mounting reinforcing ribs 233 are respectively connected to the mounting base plate 231 and the mounting vertical plate 232. Through the above arrangement, the mounting reinforcing ribs 233 enhance the stability of the mounting base 230 and increase the structural strength of the mounting base 230. To avoid accidentally injuring workers during installation, an arc-shaped relief groove 2331 is formed on the other side of the mounting reinforcing rib 233. At the same time, the design of the arc-shaped relief groove 2331 can also adapt to deformation.

[0048] During specific assembly, a combined assembly method of welding and fasteners is adopted. Among them, bolts are used to connect the cross beam 100 with the connecting seat 220, and the support frame 210 with the mounting seat 230. Welding is used to connect the support frame 210 with the connecting seat 220. The above assembly method significantly reduces the number of alignment points and weld beads during the installation of the front frame, simplifies the welding process, improves the welding efficiency, and reduces the risk of weld cracking. The bolt connection method enables the detachable and reassembly between the connecting components, making the inspection and maintenance of the corresponding components more convenient. It can quickly realize the replacement or repair of parts, greatly reducing the maintenance difficulty and cost of the front frame. Further, the rapid completion of maintenance enables the vehicle to quickly return to work, thereby improving the working efficiency of the vehicle. The bolt connection reduces the high-temperature treatment parts of the front frame, so it can reduce the thermal influence and deformation risk on the front frame.

[0049] The present application also provides a vehicle, which includes a vehicle frame, a cab, and a detachable front frame 10 as described in any of the above embodiments. The detachable front frame 10 is installed on the vehicle frame and is used to support the cab.

[0050] In the above vehicle, by setting that the plate beam 110 in the detachable front frame 10 includes a first plate body 111 and first bending portions 112 formed at opposite ends of the first plate body 111, the first bending portions 112 are detachably connected to the connecting seat 220. Among them, the integrated plate beam 110 reduces the number of alignment points and weld beads, simplifies the welding process steps, and improves the structural strength. The detachable method facilitates the inspection and maintenance of the cross beam 100 and the support platform 200, can quickly realize the replacement or repair of the above components, greatly reducing the maintenance difficulty and cost of the front frame, enabling the vehicle to quickly return to work, thereby improving the working efficiency of the vehicle. By further setting that the first reinforcing rib plate 120 is arranged in the accommodating space 113, the support stiffness of the overall detachable front frame 10 is enhanced, the service life of the detachable front frame 10 is increased, and the structure of the above detachable front frame 10 is simple, easy to produce and reduces costs.
