Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
the small front suspension fork truck outer mast as shown in fig. 1-3 has the structural characteristics that the overall structural layout is optimized again, and the optimized structure comprises the following components:
1: the configuration optimization of crossbeam frame 2 has reduced its assembly degree of difficulty when guaranteeing structural stability, and is concrete, this kind of crossbeam frame 2 adopts split type structural design, including crossbeam 4 and the rigid coupling that is located the middle part at crossbeam 4 both ends and respectively with the connecting piece 3 of both sides channel-section steel rigid coupling, connecting piece 3 is provided with two and symmetrical assembly at the both ends of crossbeam 4, and this connecting piece 3 buckles simultaneously and sets up and weld in the outer terminal surface department of channel-section steel, at the concrete implementation in-process, connecting piece 3 be formed with the notch that is used for inserting crossbeam 4 at the end portion of connecting portion 31, the assembly can be accomplished in the tip insertion notch of crossbeam 4 and implement the welding. The split structure is different from the traditional whole beam bending arrangement, as shown in fig. 3, the cross beam 4 of the split structure is inserted into the connecting piece 3, and compared with the traditional whole beam bending arrangement, the cross section of the connecting piece 3 is relatively wide, and as the connecting piece 3 is connected with the connecting rod 5 and plays a main bearing role for the connecting piece, the stress state of the bending part is particularly important, the cross section is relatively wide, and the bearing function is better; meanwhile, in order to effectively reduce the weight of the connecting piece 3, in the embodiment, preferably, the upper end surface of the connecting piece 3 is provided with the groove portion 34, the groove portion 34 is provided along the bending curve direction of the connecting piece 3, and is formed with a groove structure with an arc-shaped curved surface, so that the groove portion 34 reduces the weight of the connecting piece 3 while ensuring the structural strength thereof. It should be noted that the other end of the connecting member 3 is a second connecting portion 32, a reinforcing plate 33 which is integrally formed with the second connecting portion 32 and has a thickness change transiting through an arc surface is formed at the lower end of the second connecting portion 32, and the thickness of the reinforcing plate 33 is smaller than that of the second connecting portion 32, so as to increase the contact area between the connecting member 3 and the surface of the channel steel, and further improve the connection strength.
2: the structure of the hanging chain plate 5 is optimized, and the hanging chain plate 5 is arranged in an inverted Y-shaped structure, and comprises a connecting rod 51 fixedly connected to the connecting member 3, and a special-shaped portion 53 and a hanging chain portion 52 formed at the other end of the connecting rod 51 and extending towards each other, it should be noted that the opposite extension described in this embodiment means that the special-shaped portion 53 and the hanging chain portion 52 are arranged towards each other when extending and deforming outwards from the connecting end of the connecting rod 51.
Further, the connecting rod 51 is vertically formed with a preset inclination angle which inclines towards the inner side of the outer gantry body 1, the specific inclination angle is not limited in the embodiment, and the inclination angle is used for realizing the relative gravity center balance of the connecting rod 51 relative to the chain hanging part 52 and the special-shaped part 53, so as to achieve the effect of integrally improving the structural stability of the chain hanging plate 5; it should be noted that the inverted Y-shaped structure of the hanging chain plate 5 is arranged, so that the hanging chain part 52 and the special-shaped part 53 are not arranged on the same plane as the connecting rod 1, when the hanging chain part 52 and the special-shaped part 53 are arranged in a bending manner, the connecting rod 51 is arranged at a vertical preset inclination angle, the assembly gravity center of the connecting plate 5 can be effectively balanced, and the structural stability of the connecting plate is further improved.
Further, the connecting rod 3, the special-shaped portion 53 and the chain hanging portion 52 are integrally formed, in the specific implementation process, the chain hanging plate 5 can be integrally formed and manufactured by adopting processes such as pouring and the like, and the structural strength and the use effect are effectively improved through the integral structural arrangement.
Further, dysmorphism portion 53 is formed in the outside of place side channel-section steel and buckles the setting, and it has predetermined camber of buckling after buckling, and the channel-section steel guard action to portal body 1 not only can be implemented to the dysmorphism portion 53 that this kind of buckles the setting, combines the chaining portion 52 that sets up in opposite directions simultaneously, can the effectual balanced effect that improves its overall structure and optimizes, also further promotion its structural strength. Meanwhile, the present embodiment does not limit the specific curvature, but generally bends into a quarter arc shape.
Furthermore, the chaining part 52 is formed at the inner side of the side channel steel and is bent, and has a preset bending curvature after being bent, and the chaining part 52 is arranged by adopting a structure with a certain bending radian and extends towards the inner side of the channel steel, so that an open view can be effectively provided in the chaining process, and the operation is convenient; meanwhile, the special-shaped parts 53 arranged opposite to each other can effectively improve the balance effect of the optimization of the whole structure and further improve the structural strength. Meanwhile, it should be noted that the present embodiment does not limit the specific curvature, that is, the chain hanging part 52 may be bent into a structure with a certain curvature according to the actual use requirement.
Further, the chaining part 52 is formed on the inner side of the side channel steel and extends towards the inner side of the outer gantry body 1 by a preset length, which can be understood that the chaining part 52 adopted in the embodiment does not have a member structure with a certain bending radian, but the other end of the chaining part needs to point towards the inner side of the outer gantry body 1, and the pointing direction ensures that the chaining part 52 is located on the inner side of the vertical plane corresponding to the connecting rod 1, so that not only a certain protection effect can be achieved, but also the balance effect of the overall structure optimization can be effectively improved by the special-shaped parts 53 arranged oppositely.
Further, the special-shaped portion 53 and the zipper portion 52 are formed on the same extension plane, which means that the special-shaped portion 53 and the zipper portion 52 are located on the same plane no matter how they are bent or linearly extended.
Further, the special-shaped portion 53 and the chaining portion 52 are respectively formed on the plane of the extending plane, which means that the special-shaped portion 53 and the chaining portion 52 are on different planes after oppositely extending from the end of the connecting element 3.
The above-mentioned embodiments are only for describing the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art without departing from the design spirit of the present invention should fall into the protection scope defined by the claims of the present invention.
