Embodiment

like Figure 1-8 As shown, the embodiment of the present invention provides a double-end lifting tower crane, including a base 1, a first frame body 2 is fixedly connected to the upper surface of the base 1, and a top sleeve 7 is provided on the upper surface of the first frame body 2, and the top sleeve 7 A hydraulic cylinder 16 is fixedly connected to the inside of the hydraulic cylinder 16, and the output end of the hydraulic cylinder 16 is fixedly connected to the first frame body 2, and the top sleeve 7 can be pushed up and down by the expansion and contraction of the hydraulic cylinder 16, so that the second frame body 4 and the third frame body 4 can be moved up and down. The height of the frame body 8 is adjusted, and the upper surface of the top sleeve 7 is fixedly connected with the turning plate 5, and the fixed frame 6 can drive the second frame body 4 and the third frame body 8 to rotate by controlling the turning plate 5 from the outside. A fixing frame 6 is fixed...

Abstract

The invention provides a double-hoisting-end hoisting tower crane, and relates to the technical field of hoisting tower cranes. The double-hoisting-end hoisting tower crane comprises a base, a first frame body is fixedly connected to the upper surface of the base, a top sleeve is arranged on the upper surface of the first frame body, a rotating plate is fixedly connected to the upper surface of the top sleeve, a fixing frame is fixedly connected to the upper surface of the rotating plate, and a second frame body is fixedly connected to the side surface of the fixing frame; and a gravity mechanism is fixedly connected to the interior of the second frame body. By arranging a gravity mechanism, the weight of a second frame body can be increased through a first bearing block and a second bearing block, when a third frame body is used for tower crane objects, the weight between the second frame body and the third frame body is balanced, meanwhile, the second bearing block can be pushed to move through stretching and retracting of an electric telescopic rod, and the weight of the second frame body is increased. The second bearing block can extend out of the first bearing block, the weight of the second frame body is concentrated on the lower portion, and the device is not prone to unbalance when the tower crane is used for carrying out tower crane on an object.

Description

technical field [0001] The invention relates to the technical field of hoisting tower cranes, in particular to a double hoisting end hoisting tower crane. Background technique [0002] Tower cranes are the most commonly used lifting equipment on construction sites, also known as "tower cranes". , concrete, steel pipes and other construction raw materials. The tower crane is an indispensable equipment on the construction site. [0003] The function of the tip of the tower crane is to bear the upper load from the jib pull rope and the balance arm pull rope, and directly transmit it to the tower body structure through the rotary tower, turntable, bearing and other structural components. The top of the self-elevating tower has a truncated cone column type, a forward or backward truncated cone column type, a herringbone frame type and a diagonal support frame type. All upper slewing tower cranes need to be equipped with a counterweight, and its function is to support the count...
