Embodiment Construction

[0028] The present invention will be further described below in conjunction with specific embodiment:

[0029] The towerless cable crane of the present invention is applicable to the cable hoisting device for transporting heavy objects between V-shaped canyons. The design of the "tube spiral friction winch" and "running trolley" solves the problem of unstable operation of the cable hoisting device's operating mechanism and hoisting mechanism.

[0030] The hoisting weight is passed to the running trolley through the suspension hook, hoisting rope, and pulley block, and the running trolley is suspended on the load-bearing cable 12 through the running wheels, and finally the load-bearing cable 12 transmits the weight to the cable saddle foundation 10.

[0031] The load-bearing cable deflection system 3 is connected to the cable saddle foundation 10 through the cable saddle 1 and the embedded belt 11 of the middle bearing frame. The ropes 7 and 8 wound on the hoist pass through th...

Abstract

The invention relates to a cable crane, in particular to a non-tower cable crane, comprising a pull cable, an operating trolley, a winch and a jackstay machine; the invention is characterized in that a stable plate unit structural member is embedded in foundation and led to be connected with a combined cable saddle; the tensile force of a main rope is transferred to the foundation. In the non-tower cable crane of the invention, the stable plate unit structural member is a steel member, is fixed in the foundation and connected into a whole with the foundation; the winch is a screw friction winch, the notch of which is a semicircular rope channel; a hanger shaft is arranged between a travel wheel of the jackstay machine and a supporting wheel system so as to lead the travel wheel to be hinged with the supporting wheel system. The invention has the beneficial effects of reducing constructional cost, simplifying construction technique, improving construction precision, simplifying the operating system and ensuring the safety and the reliability of construction.

Description

technical field [0001] The invention relates to a cable crane, in particular to a cable crane without a tower. Background technique [0002] At present, most domestic cable lifting devices are basically composed of towers, load-bearing cable deflection systems, traction cable deflection systems, hoisting cable deflection systems, power sources, and rear anchors. The movement and lifting of heavy objects can be realized by using the ropes of two winches one in and one out. However, compared with this type of cable hoisting device, there are disadvantages such as high tower investment cost, a large number of winches, and unstable operation of the operating mechanism and hoisting mechanism. Contents of the invention [0003] The invention is a kind of cable hoisting device which uses a steel cable suspended between two fulcrums as a load-bearing structure, and uses a load-bearing running trolley to move back and forth on it to carry out the loading operation of heavy objects...
