Thus, features defined with "first", "second" or "third" can include, explicitly or implicitly, one or more of such features. In the description of the present application, the meaning of "a plurality of" or "several" is two or more, unless explicitly specified otherwise.

[0032] It should be noted that the structures, proportions, sizes, etc. shown in the drawings of the present application are only used to illustrate the content disclosed in the present application, to enable those skilled in the art to understand and read, and are not used to limit the conditions under which the present application can be implemented, and therefore do not have technical significance.

[0033] Please refer to Figures 1 to 4 The technical scheme of the present application is described in a specific embodiment of the explosion-proof forklift balance weight detection device. The device comprises a positioning plate 1, a positioning pin 2 and a transfer unit 3.

[0034] As shown in Figures 1 to 4 In the present example, the explosion-proof forklift balance weight detection device is provided to better detect the installation size of the balance weight. Therefore, the outer shape of the positioning plate 1 matches the standard outer shape of the explosion-proof control box setting cavity, and a bearing part is further provided in the explosion-proof control box setting cavity. In the present embodiment, the bearing part is a chamfer provided at the edge of the explosion-proof control box setting cavity, and the bottom of the chamfer is a flat surface. Therefore, the bottom of the positioning plate 1 can be arranged on the flat surface of the chamfer bottom, and to better fit the standardized balance weight, the thickness of the positioning plate 1 is equal to the height difference between the top surface of the bearing part and the edge of the explosion-proof control box setting cavity, that is, the distance between the chamfer bottom flat surface and the edge of the explosion-proof control box setting cavity.

[0035] The balance weight installation positioning mainly relies on the plug-in positioning of the installation hole. Therefore, a plurality of positioning pins 2 are provided on the inner side surface of the positioning plate 1 in contact with the explosion-proof control box setting cavity. The positioning pins 2 correspond to the standard position of the balance weight installation hole in the explosion-proof control box, and the length of the positioning pins 2 matches the standard depth of the balance weight installation hole. By observing whether the positioning pins 2 can be fully inserted into the balance weight installation hole, if they cannot be inserted, it can be determined that the relative position size of the balance weight control box installation hole is unqualified. Furthermore, it can be observed whether the positioning plate 1 is in contact with the balance weight control box installation surface. If it is not in contact, it can be determined that the depth size of the balance weight control box installation hole is unqualified.

[0036] In addition, in order to facilitate the transportation of the explosion-proof forklift counterweight detection device and facilitate batch testing, a transfer unit 3 is also provided on the outer side of the positioning plate 1. Through the transfer unit 3, the positioning plate 1 and the positioning pin 2 can be more conveniently transported to achieve batch multiple testing.

[0037] Preferably, when the explosion-proof forklift counterweight detection device is not in use for detection, in order to facilitate storage and storage, in this embodiment, the positioning pin 2 is detachably arranged on the inner side of the positioning plate 1. Specifically, the positioning pin 2 is arranged on the positioning plate 1 through a threaded connection. Therefore, when there is no detection condition, the positioning pin 2 can be disassembled for easy storage.

[0038] Furthermore, in this embodiment, the number of the positioning pins 2 is consistent with the number of the counterweight mounting holes, which is 4 and distributed around the inner side of the positioning plate 1 .

[0039] As a preferred Figures 1 to 4 As shown, in this embodiment, the transfer unit 3 is specifically a handle assembly, and the handle assembly is provided with a support portion 4 and a gripping portion 5 to form an enclosed space; specifically, Figure 1 As shown, there are two supporting parts 4, which are vertically arranged on the outer side of the positioning plate 1. The grabbing part 5 connects the top surfaces of the two grabbing parts 5 to form a closed space by enclosing them, which is convenient for operators to directly grab and carry or use hooks, ropes, etc. for lifting and transporting.

[0040] Furthermore, in order to facilitate the storage and placement of the explosion-proof forklift counterweight detection device when it is not in use for detection, the handle assembly can also be detachably mounted on the outside of the positioning plate 1. Specifically, the support portion 4 is threadedly mounted on the positioning plate 1, so that the positioning pin 2 can be disassembled for easy storage when there is no detection.

[0041] Further, if Figures 1 to 4 As shown, in this embodiment, the number of the handle assemblies provided on the outer side of the positioning plate 1 is two, which can facilitate the operator to pick up and carry it with both hands.

[0042] Furthermore, the handle assembly is arranged on the outside of the positioning plate 1 so as to make it more convenient for the operator to carry it with both hands. Figures 1 to 4 As shown, the handle assembly is symmetrically distributed on both sides of the outer surface of the positioning plate 1 relative to the center of the positioning plate 1. Specifically, in this embodiment, the handle assembly is symmetrically distributed on the left and right sides of the outer surface of the positioning plate 1, which is more suitable for the operator to carry it with both hands.

[0043] As preferred, in another embodiment, only the fit degree of the explosion-proof forklift counterweight detection device is used to judge the counterweight installation size, when the installation error exists in the explosion-proof control box setting cavity, the problem that the reason cannot be accurately judged, therefore, in other embodiments, the observation window is further arranged on the positioning plate 1, the observation window is made of transparent material, the explosion-proof control box setting cavity can be observed to judge which size of the explosion-proof control box setting cavity has installation error for rework adjustment.

[0044] More preferably, in order to better observe the visual angle, in another embodiment, the setting position of the observation window is arranged at the center of the positioning plate 1, which can facilitate the observation of the whole installation condition of the explosion-proof control box setting cavity.

[0045] As preferred, in the prior art, due to the commonality of the large volume and weight of the counterweight, the installation hole and position size of the explosion-proof control box on the counterweight are difficult to detect, in the present application, the explosion-proof forklift counterweight detection device detects by replacing the standard contour of the counterweight, so as to achieve the purpose of rapid detection, and in order to facilitate mass detection, the positioning plate 1, the positioning pin 2 and the transfer unit 3 are made of lightweight material, so as to reduce the labor intensity of repetitive work.

[0046] The above description of the disclosed embodiments enables a person skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
