[0025] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the scheme of the utility model will be further described below. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] Reference Figures 1 to 6 As shown, this embodiment provides a counterweight device, including at least one counterweight unit, two adjacent counterweight units are plug-connected, and the counterweight unit includes at least one counterweight plate 1, at least one shell 2 and at least one cover plate 3.

[0028] The shell 2 has a storage space for accommodating the counterweight plate 1, and a groove 201 is provided at the bottom of the shell 2. The cover plate 3 is connected to the top of the shell 2, and a boss 301 adapted to the groove 201 is provided at the top of the cover plate 3. Specifically, the counterweight plate 1 is placed in the shell 2. By changing the number of counterweight plates 1 in the shell 2, the weight of a single counterweight unit can be adjusted. It is only necessary to add the counterweight plate 1 to the shell 2 as needed. By providing the adapted groove 201 and boss 301, a combination of multiple counterweight units is achieved to meet the weight requirements of the counterweight in different load tests.

[0029] Further, see Figure 1 , Figure 2 and Figure 3 As shown, a plurality of pin seats 4 are evenly arranged on the outer periphery of the housing 2, and both ends of the pin seats 4 are plug-connected with the corresponding pin seats 4 on the housing 2 arranged in the vertical direction. Specifically, the two ends of the pin seats 4 are respectively provided with an adapted male end and a female end. When a plurality of counterweight units are assembled and placed, the pin seats 4 of the two counterweight units in the vertical direction are plug-connected, that is, the male end of the upper pin seat is plug-connected with the female end of the lower pin seat, so that the connection between the two counterweight units can be realized, thereby improving the stability of the counterweight device.

[0030] Reference Figure 4As shown, both ends of the pin shaft seat 4 are provided with pin shaft holes 5, and the height of the pin shaft seat 4 is greater than the height of the housing 2. Specifically, the male end and the female end of the pin shaft seat 4 are provided with pin shaft holes 5. When the male end of the upper pin shaft seat is plug-connected with the female end of the lower pin shaft seat, the pin shaft hole on the male end of the upper pin shaft seat coincides with the pin shaft hole on the female end of the lower pin shaft seat. By inserting the pin shaft into the coincident pin shaft hole 5, the connection of multiple counterweight units is realized, and the stability of the counterweight device is further improved. At the same time, the height of the pin shaft seat 4 is greater than the height of the housing 2, that is, the female end of the pin shaft seat 4 is higher than the housing 2. At this time, the pin shaft hole 5 on the female end can be used for lifting the counterweight device.

[0031] Further, see Figure 3 As shown, the housing 2 is a square frame, and the number of the pin seats 4 is four. The four pin seats 4 are respectively arranged at the centers of the four sides of the housing 2, and the housing 2 is welded by steel plates.

[0032] To ensure the service life of the shell 2, flexible parts are provided on the inner bottom surface and the outer bottom surface of the shell 2. The flexible parts provided on the inner bottom surface avoid rigid collision between the counterweight plate 1 and the shell 2, and the flexible parts provided on the outer bottom surface increase the friction between the shell 2 and the ground, thereby improving the stability of the counterweight device.

[0033] Continue to refer to Figure 3 As shown, a cross beam 6 is provided at the center of the housing 2 to divide the interior of the housing 2 into four accommodating spaces. Specifically, the cross beam 6 divides the interior of the housing 2 into four identical accommodating spaces, thereby improving the accuracy of adjusting the counterweight.

[0034] Reference Figure 6 As shown, a plurality of first threaded holes 101 are evenly arranged on the counterweight plate 1. Specifically, the counterweight plate 1 is a steel plate with a certain thickness. A plurality of first threaded holes 101 are evenly arranged on the counterweight plate 1. The first threaded holes 101 are used to install eye screws to facilitate lifting the counterweight plate 1 into the shell 2.

[0035] Reference Figure 5 As shown, a plurality of bolt through holes 302 are evenly arranged at the edge of the cover plate 3, a plurality of third threaded holes 202 are evenly arranged at the edge of the housing 2 corresponding to the bolt through holes 302, and a plurality of second threaded holes 303 are evenly arranged on the boss 301. The bolt through holes 302 and the third threaded holes 202 are arranged correspondingly, so as to realize the threaded connection between the cover plate 3 and the housing 2. The second threaded holes 303 are used to install eye screws to hang the cover plate 3 to the top of the housing 2. When a single counterweight unit is used, a rod or a plate with holes can also be externally connected to the second threaded holes 303 to realize the adjustment of the weight of the single counterweight unit.

[0036] When the counterweight device is used in practice, the number of counterweight units is selected as needed. When a single counterweight unit is used, the counterweight plate 1 is hoisted in the shell 2 as needed, and the cover plate 3 is hoisted to the top of the shell 2 and connected. At this time, the single counterweight unit is assembled; if multiple counterweight units are needed, the assembled single counterweight units are stacked, so that the grooves 201 and bosses 301 of the two adjacent counterweight units are plugged and connected, and then the pin shaft passes through the pin shaft seat 6 to realize the combined installation of multiple counterweight units.

[0037] It should be noted that, in this article, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0038] The above description is only a specific embodiment of the utility model, so that those skilled in the art can understand or implement the utility model. Various modifications to these embodiments will be obvious 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 utility model.
