The invention discloses a device for fixing an upper pivoting body of a construction engineering machine, relates to the technical field of engineering machinery, and solves the problems that an existing upper pivoting body fixing device is difficult to guarantee uniform attachment between brake surfaces in use, the local stress condition is easy to occur, the local abrasion is serious, the brakesurfaces are small, the brake effect is not ideal, and the service life is shorter. The device comprises a fixing piece, and the top of the fixing piece is rotationally connected with a set of upper pivoting body piece; six sets of clamping sliding pieces are arranged in the fixing piece in a circumferential array manner and connected with the fixing piece in a sliding manner; and twelve sets of clamping pincer blocks are arranged in the fixing piece in a circumferential array manner. By means of the device, the clamping force is uniform, the good braking effect can be guaranteed, meanwhile, the problem of serious local abrasion caused by local stress is avoided, the good clamping braking effect is guaranteed even if certain abrasion exists, the braking force arm is larger, the braking effect is better, the working stability is high, the abrasion resistance of the braking surfaces is high, and the service life is longer.

    本发明公开了一种用于固定建筑工程机械的上部枢转体的装置,涉及工程机械技术领域,解决了现有的上部枢转体固定装置在使用中难以保证制动面之间的均匀贴紧,容易出现局部受力的状况,局部磨损严重,制动面小,制动效果不理想,使用寿命较短的问题,包括固定件;所述固定件的顶部转动连接有一组上部枢转体件;所述固定件内部圆周阵列排布滑动连接有六组夹紧滑动件;所述固定件内部圆周阵列设置有十二组夹紧钳块。本发明夹紧力均匀,能够保证良好的制动效果,同时避免了局部受力造成的局部磨损严重的问题,即使有一定的磨损同样保证具有良好的夹紧制动效果,制动力臂更大,制动效果更好,工作稳定性强,制动面耐磨性强,使用寿命更高。
