Embodiment Construction

[0034] The present invention is described in detail below with reference to accompanying drawing and embodiment:

[0035] attached Figure 1-3 It can be known that a main cable traverse type rear anchor of a cable crane,

[0036] Including rear anchorage 1, main cable bearing frame 2, anchorage mechanical room 3, traverse slideway 4;

[0037] The main cable bearing frame 2 is set on the side of the rear anchorage 1 away from the mid-span of the bridge;

[0038] Anchor mechanical room 3 is arranged on the top surface of rear anchorage 1;

[0039] The main cable force frame 2 and the anchorage mechanical room 3 are fixed together by welding;

[0040] A traverse slideway 4 is set between the rear anchorage 1, the main cable bearing frame 2, and the anchorage mechanical room 3.

[0041] A total of four rows of traversing slideways 4 are arranged on the rear anchorage, among which three rows of traversing slideways 4 are arranged on the top surface of the rear anchorage 1, and ...

Abstract

The invention relates to a transverse-moving-type stern anchor for a main cable of a cable crane. The transverse-moving-type stern anchor comprises a stern anchorage, a main cable force-bearing frame,an anchorage mechanical room and transverse-moving slideways. The anchorage mechanical room is arranged on the top face of the stern anchorage. The transverse-moving slideways are formed between thestern anchorage and the anchorage mechanical room. The stern anchorage is provided with the four rows of transverse-moving slideways, and the three rows of transverse-moving slideways are arranged onthe top face of the stern anchorage, and the other row of transverse-moving slideways is arranged on the bottom face of the outer edge of the stern anchorage. The anchorage mechanical room is welded and fixed to the transverse-moving slideways on the top face of the stern anchorage. The main cable force-bearing frame and the anchorage mechanical room are fixed in a welded mode. The transverse-moving-type stern anchor for the main cable of the cable crane is less limited by geology and terrain and is suitable for the large-tonnage and long-span cable crane, limitation of the stern anchorage tothe geology and terrain conditions is reduced, the transverse-moving-type stern anchor is especially suitable for mountainous areas with the steep slope, the anchorage mechanical room moves transversely to simultaneously drive a cable crane load-bearing cable, a traction cable and a hoisting cable to move transversely, and operation of an anchorage transverse-moving system is simplified.

Description

technical field [0001] The invention relates to a cable crane used in bridge engineering, in particular to a main cable traverse rear anchor of the cable crane. Background technique [0002] At present, the cable cranes used in long-span bridges usually need to have the function of moving across the bridge, and its lateral movement function is mainly realized by the lateral sliding system of the rear anchor and the lateral movement of the saddle on the top of the cable crane tower . The latter only moves the cable saddle on the top of the cable crane tower due to the constant position of the anchor after the cable crane, which will cause the change of the main cable stress of the cable crane and cause a greater safety hazard. [0003] The existing rear anchor lateral slip system is mainly the integral slip of the rear anchor. Chinese patent application CN 201296609 Y proposes a mobile ground anchor device for a cable crane rear anchor used in bridge construction. However,...
