[0017] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.
[0018] like Figure 1-3As shown, an embodiment of the utility model proposes a crane counterweight with stable installation, comprising: a first counterweight block 1, a second counterweight block 2 is slidably installed on the top of the first counterweight block 1, and the first counterweight block 1 and the second counterweight block 2 are in contact with each other; a support plate 3, two in number, the support plate 3 is fixedly installed on one side of the first counterweight block 1; a plurality of connecting blocks 4, a plurality of connecting blocks 4 are fixedly installed on the top of the support plate 3; a rotating assembly 5, a plurality of rotating assemblies 5, a plurality of rotating assemblies 5 are installed between the two connecting blocks 4, and are used to fix the second counterweight block 2, the rotating assembly 5 comprises a rotating column 51 fixedly installed between the two connecting blocks 4, a rotating block 52 is rotatably sleeved on the outer peripheral side of the rotating column 51, and a screw 53 is rotatably installed on one side of the rotating block 52; a rectangular block 6, the rectangular block 6 is fixedly installed on the top of the support plate 3; a plurality of clamping devices 7, a plurality of clamping devices 7 are fixedly installed on the top of the rectangular block 6, and are used to clamp and fix the rotating block 52.
[0019] When the crane needs to be counterweighted, the second counterweight 2 needs to be pushed eastward from one side of the first counterweight 1 so that the first counterweight 1 fits with the second counterweight 2, and then the rotating block 52 is rotated so that the rotating block 52 rotates to 90° on the rotating column 51, and then the clamping device 7 is started to clamp and fix the rotating block 52, so as to avoid the shaking of the rotating block 52, the tilting of the crane, and the influence on the use of the crane. Then the screw 53 is inserted from one side of the rotating block 52 to fix the second counterweight 2, which is beneficial to strengthen the connection between the first counterweight 1 and the second counterweight 2, thereby improving the stability of the device, and is beneficial to ensuring the safety of workers. The device is simple to operate, has strong applicability, and is convenient for workers to use.
[0020] like Figure 1 As shown, in some embodiments, the clamping device 7 includes an electric push rod 71 fixedly mounted on the top of the rectangular block 6, a long plate 72 is fixedly mounted on the telescopic end of the electric push rod 71, and a U-shaped groove 73 is opened at one end of the long plate 72.
[0021] When the rotating block 52 rotates to 90°, the electric push rod 71 is started to drive the long plate 72 to move toward the rotating block 52, so that the U-shaped groove 73 on the long plate 72 fits with the rotating block 52, thereby facilitating the fixing of the rotating block 52.
[0022] like Figure 1 As shown, in some embodiments, the U-shaped groove 73 on the long plate 72 is engaged with the rotating block 52 .
[0023] Starting the electric push rod 71 drives the long plate 72 to move, so that the U-shaped groove 73 on the long plate 72 is engaged with the rotating block 52, which is conducive to clamping and fixing the rotating block 52, avoiding the shaking of the rotating block 52, thereby improving the stability of the device.
[0024] like Figure 2 As shown, in some embodiments, a first L-shaped groove 8 is provided on the first counterweight block 1, a second L-shaped groove 9 is provided on the second counterweight block 2, the second counterweight block 2 is clamped with the first L-shaped groove 8, and the first counterweight block 1 is clamped with the second L-shaped groove 9.
[0025] Since the first counterweight block 1 and the second counterweight block 2 are clamped together, the connection between the first counterweight block 1 and the second counterweight block 2 is more stable and looseness is avoided.
[0026] like Figure 2 As shown, in some embodiments, a metal block 11 is movably inserted and installed on one side of the second counterweight block 2, and the number is two. The two metal blocks 11 are fixedly inserted through the first counterweight block 1 and the second counterweight block 2.
[0027] When the first counterweight 1 and the second counterweight 2 are connected, the metal block 11 is inserted from one side of the first counterweight 1 so that the metal block 11 passes through between the first counterweight 1 and the second counterweight 2, thereby improving the stability of the device.

[0029] When the two counterweights need to be removed, remove the screws 53 and rotate the rotating block 52, start the electric push rod 71 to drive the U-shaped groove 73 on the electric push rod 71 to disengage the rotating block 52, and then the rotating block 52 rotates to the groove 10 on the support plate 3, which is beneficial to fix the rotating block 52 and facilitate the placement of the rotating block 52.
[0030] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention 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.
