Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of stacker trucks, in particular to a detection die frame for a fork frame of a stacker truck. Background Art
[0002] As a crucial piece of equipment in logistics and warehousing systems, the stability and precision of a stacker's fork frame structure are directly linked to the efficiency and safety of the entire handling operation. Traditional fork frame designs often utilize a welded combination of a lifting frame and forks. While this structure provides a certain degree of overall strength, the forks, due to their complex geometry and material properties, are susceptible to deformation due to uneven heating during the welding process. This deformation not only affects the fork frame's appearance but, more importantly, can cause interference with the fork legs or other critical components when assembled to the stacker, compromising the stacker's proper operation and safety.
[0003] Currently, there are two main methods for detecting the fork frame structure of stacker trucks, but each has certain limitations and cannot meet the needs of efficient, accurate and large-scale detection.
[0004] The first method involves placing the fork frame on a dedicated testing platform. While this method can simulate the fork frame's assembly state to a certain extent, the operation is relatively complex and requires precise adjustments by professionals to ensure the fork frame's accurate positioning on the platform.
[0005] The second inspection method involves scanning the fork carriage using a 3D scanner. A 3D scanner captures the three-dimensional coordinate data of the fork carriage surface, generating a precise 3D model. This method theoretically offers high accuracy, capable of detecting even the slightest deformation and dimensional deviations of the fork carriage. However, in practice, 3D scanners can take a relatively long time to inspect, especially for large or complex fork carriage structures, where the scanning process can take hours or even longer. This not only affects inspection efficiency but also limits the method's application in high-volume inspection scenarios. Furthermore, the high equipment and maintenance costs of 3D scanners make them a significant expense for many companies.
[0006] In view of this, we propose a detection mold frame for stacker fork frame. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] Example
[0024] At present, the fork frame structure of stacker trucks is welded together by lifting frame and fork. Due to structural reasons, the fork frame is severely deformed after welding. At the same time, it is difficult to detect the size of the fork frame alone, which leads to interference with the fork legs of the vehicle body after assembly. There are currently two detection methods: one is to place it on the platform for detection, which is complicated to operate and the detection results are inaccurate; the other is to use a 3D scanner for detection, which takes a long time and cannot be used for large-scale detection.
[0025] Therefore, see Figure 1 and Figure 2 As shown, the purpose of this embodiment is to provide a detection mold frame for a stacker fork frame, which includes a base 100. Taking into account the need to determine whether the welded fork frame must be compatible with the lifting frame for installation and to avoid interference between the fork body and the fork legs of the vehicle body, a positioning groove 103 is provided in the middle of the top of the base 100. The positioning groove 103 is parallel to the long side of the base 100 and serves as a reference line for determining the welding and fixing position of the fork body in the fork frame. Limiting members 200 are provided on both sides of the long side of the top of the base 100. The limiting members 200 are symmetrically arranged with the positioning groove 103 as the axis. The two limiting members 200 on the same side adjust the spacing according to the preset opening size, which serves as a standard for determining the size of the inner mast in the fork frame.
[0026] The improvement of this embodiment is that: first, the opening size of the two limit members 200 is determined according to the existing lifting frame size, then the fork body and the inner mast are welded into a fork frame, and finally the inner mast is inserted between the two limit members 200 for fixation. The insertion state of the inner mast is used to determine whether the fork is compatible with the lifting frame, and the positioning groove 103 is used to determine whether the fixed position of the fork body and the inner mast is correct, thereby quickly detecting the dimensional compliance of the stacker fork frame after welding. The operation is simple, the detection accuracy is high, and batch detection can be achieved.
[0027] See Figure 3 As shown, further, the base 100 and the limiting member 200 are disclosed:
[0028] When the limit member 200 is used to limit and fix the fork frame, the limit member 200 is subjected to the thrust of the fork frame. In order to ensure that the position of the limit member 200 does not change, the base 100 is provided with a plurality of assembly holes 101. The limit member 200 includes a bottom plate 203. The bottom plate 203 is provided with through holes corresponding to the assembly holes 101. Connecting bolts penetrate the through holes and the assembly holes 101. After determining the size of the lifting frame, the position of the bottom plate 203 and the assembly holes 101 is adjusted, and the bottom plate 203 is fixed to the surface of the base 100 with bolts to fix the limit member 200.
[0029] In consideration of limiting the inner door frame, the limiting member 200 includes a channel steel 201, which is provided with a slide groove. The U-shaped shape of the slide groove limits the moving direction of the inner door frame, thereby reducing the shaking of the inner door frame. At the same time, in order to prevent the inner door frame from directly colliding with the bottom plate 203 and thus causing damage to the bottom plate 203, a detachable limiting seat 204 is provided at the bottom of the slide groove. The bottom of the limiting seat 204 is fixed to the bottom plate 203 by bolts, thereby preventing the inner door frame from directly colliding with the bottom plate 203.
[0030] Considering the heavy weight of the fork frame as a whole, an unsuitable fork frame may slide downward due to inertia when inserted into the slide grooves on the opposite sides of the two limit members 200, which may eventually cause a break between the channel steel 201 and the bottom plate 203. Therefore, one end of the channel steel 201 is fixed to the surface of the bottom plate 203, and a side plate 202 is fixed at the connection between the channel steel 201 and the bottom plate 203. The side plate 202 serves as a reinforcement plate to improve the stability of the connection between the channel steel 201 and the bottom plate 203.
[0031] Since the entire detection mold frame is very heavy and difficult to move by manpower, in order to facilitate the movement of the entire device, hooks 102 are symmetrically fixed on both sides of the base 100, so that the entire detection mold frame can be removed by lifting after use, saving manpower.
[0032] It should be noted that due to the wide variety of fork frame products, in order to improve the applicability of the entire detection mold frame and expand its scope of use, the hole spacing between adjacent assembly holes 101 on both sides of the base 100 is not consistent. The assembly holes 101 on one side of the base 100 are used to cooperate with the bottom plate 203 of the limit member 200 to adapt to one type of fork frame product.
[0033] In summary, the working principle of this solution is as follows:
[0034] 3. The cam 203 is fixed to the base 100 through the assembling holes 101, and the limit seat 204 is installed at the bottom of the channel steel 201 slot, and the limit seat 204 is fixed to the surface of the base plate 203 by bolts. Then, the fork body and the inner door frame are assembled and welded into a fork frame. Finally, the inner door frame is inserted between the channel steel 201 slots of the two limit members 200 for fixing. The fork is determined to be compatible with the lifting frame by the state of the inner door frame insertion. Then, the positioning slot 103 is used as the center axis, and the distance between the fork body and the positioning slot 103 is measured by eyes or a ruler to determine whether the fixed position of the inner door frame is correct. When both are correct, it means that the fork frame meets the installation standards.
[0035] Although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
[0036] Therefore, the above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application; that is, all equivalent modifications made according to the scope of the claims of the present application are within the scope of protection of the claims of the present application.
