Embodiment Construction

[0028] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0029] A specific embodiment of the crane with adjustable counterweight position of the present invention, such as figure 1 As shown, the crane with adjustable counterweight position (hereinafter referred to as the crane) includes the main body of the crane and the counterweight. The main body of the crane includes the bracket 1 and the hoisting box 2. The bottom of the hoisting box 2 is provided with a support plate 3, and the counterweight 4 passes through The hanging lugs 5 are guided and supported on the support plate 3 . Specifically, such as figure 2 As shown, the support plate 3 is provided with three rolling grooves 6 extending along the guiding movement direction of the counterweight 4, and the two ends of the rolling groove 6 in the length direction are blind ends provided with a blocking structure. The side wall of the groove is formed, the...

Abstract

The invention relates to a crane capable of adjusting a counterweight position. The crane capable of adjusting the counterweight position comprises a crane main body and a counterweight; guide rails are arranged on the crane main body; hanging lugs are arranged on the counterweight; the counterweight is guided and supported on the guide rails through the hanging lugs; rolling ball sets used for supporting the hanging lugs in the vertical direction are arranged between the guide rails and the hanging lugs; and either each of the guide rails or each of the hanging lugs is provided with rolling ball retaining holes allowing corresponding rolling balls in the rolling ball sets to be partially embedded, and the other one of each of the guide rails and each of the hanging lugs is provided with arolling fit face used for being in rolling fit with the rolling balls. The counterweight is supported on the guide rails in a guiding and moving mode through the hanging lugs, and the rolling balls are positioned through the rolling ball maintaining holes, so that the stable operation of the rolling balls is guaranteed; and the guide rails achieve guiding and supporting of the hanging lugs through the rolling ball set, so that the rolling ball abrasion is small, guiding is reliable, the stable operation of the counterweight is facilitated, and the operation safety of the crane is guaranteed.

Description

technical field [0001] The invention relates to a crane with adjustable counterweight position. Background technique [0002] Truck cranes have been widely used in modern engineering construction, mainly in engineering infrastructure and other industries, and are an indispensable and important member of construction machinery products. In each mechanism of the crane, the counterweight plays an important role in maintaining the balance of the crane. Its weight and suspension position directly affect the hoisting capacity and safety and stability of the crane. In order to improve the lifting capacity of the truck crane during work, the method of increasing the counterweight or moving the position of the center of gravity of the counterweight is usually used. For large and medium-sized cranes, movable counterweights are usually configured to adjust the overall weight of the counterweight. The movable counterweight The weight is stored in the compartment when not in use. Howev...
