Furthermore, both ends all are equipped with a connecting rod about the crossbeam, the connecting rod and the tight fit of upper casing top. Like this, the crossbeam is together fixed through the mode of socket joint between and is in the same place with the bracing piece, and it is comparatively convenient to assemble and dismantle, can be convenient for fold up the gallows, simultaneously, still has better steadiness.

Furthermore, an arc-shaped rod is fixed on the cross beam of each lifting frame along the length direction of the cross beam, and at least two reinforcing rods are arranged between the arc-shaped rods and the cross beam. Like this, arc pole and reinforcement bar can share partial external force, have effectively increased the intensity of crossbeam simultaneously to increase the life of crossbeam.

Furthermore, a hydraulic oil cylinder which is transversely arranged is arranged at the left end and the right end of the cross beam of each lifting frame, and one end of the hydraulic oil cylinder, which is close to the cross beam, is abutted against the end part of the cross beam. Therefore, when the lifting frame is used, the left end and the right end of the oil cylinder can be abutted against the inner wall of the operation space and the end part of the cross beam respectively by controlling the hydraulic oil cylinder, the stability of the lifting frame can be effectively improved, and the lifting frame is prevented from laterally moving due to external force in the lifting process. In addition, the arrangement can also share part of the gravity borne by the cross beam to the inner wall of the operation space, so that the service life of the cross beam is further prolonged, and the deformation of the cross beam is effectively prevented.

Furthermore, the bottom of the lower casing is also provided with a chassis, and the chassis is provided with a plurality of inclined struts of which the tail ends are fixed with the outer wall of the lower casing through welding. Like this, through chassis and bracing, effectively increased the atress area of lower sleeve pipe bottom, made the bracing piece can stand ground comparatively firmly.

Furthermore, an installation frame is fixed on the support rod of each lifting frame, a fixed pulley is arranged on the installation frame, and the fixed pulley is fixedly installed on the installation frame through a rotating shaft; the middle part of the hoisting inhaul cable is fixed on a reel of the winch after sequentially bypassing the hoisting pulley and the fixed pulley on the same side. Like this, the fixed pulley that adds on the bracing piece can share the partial pressure of hanging the pulley to reduce the atress that lifts by crane the cable, make the operator just can rotate the capstan winch with littleer power, it is more convenient to operate.
