Abstract
The utility model discloses a fixed cantilever crane, which comprises a lifting device, a crane carriage and a longitudinal beam, wherein the lifting device comprises a boom and a V-shaped moving part arranged on the boom; the V-shaped moving part is connected with an upper hydraulic cylinder; the upper hydraulic cylinder is connected with an upper beam capable of regulating an angle in leftward and rightward directions by the expansion and the retraction of the upper hydraulic cylinder; the upper beam is connected with a frame structure, and is positioned over the frame structure; a lower beam is arranged on the middle part of the frame structure, is connected with a lower hydraulic cylinder, and can regulate an angle in forward and backward directions by the expansion and the retraction of the lower hydraulic cylinder. According to the technical scheme, the problem that the posture of a bridge section cannot be regulated by an ordinary lifting device is solved, so that the mounting accuracy of the bridge section is ensured, time for the regulation of the bridge section is greatly reduced, and the working efficiency is improved.
Description
Technical field
The utility model belongs to bridge crane gear technical field, specifically relates to a kind of fixed boom that is applicable to bridge construction and hangs.
Background technology
Needs along with China's economic construction, the road and bridge construction of China has entered into a fast-developing new period, the thing followed is exactly the flourish of new technology and new equipment, wherein comparatively typical case aims at section assembling formula bridge and the fixed boom developed hangs, and by feat of its superior performance, once releasing, just becomes key equipment indispensable in highway bridge construction.Because the beam body of section assembling formula bridge is to be spliced by a plurality of sections, so in the process of setting up, it is most important whether each sections installation site and attitude accurately just seem, present problem is that the stringer chassis of the upper dolly that hangs by fixed boom and door frame bottom only can be realized the adjustment of sections position, and the adjustment of attitude cannot realize.So just need to develop a kind of suspender, realize this function.
Summary of the invention
The utility model is mainly to solve the existing technical problem of above-mentioned prior art, provide a kind of fixed boom to hang, by hanger structure being made into hinged two parts up and down, and install hydraulic cylinder additional between upper and lower two parts, suspender aloft can be adjusted the attitude of beam section, solved common suspender and cannot complete the problem that beam section attitude is adjusted, thereby guaranteed the installation accuracy of beam section, greatly reduce beam section and adjusted the time used, improved operating efficiency.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of fixed boom hangs, comprise suspender, trolley and longeron, described suspender is comprised of suspension rod and the V-type movable part being arranged on suspension rod, described V-type movable part connects upper hydraulic cylinder, described upper hydraulic cylinder is connected with top rail, described top rail is flexible by upper hydraulic cylinder, adjusts the angle of left and right directions; Described top rail is connected with frame construction, and described top rail is directly over frame construction; In the middle of described frame construction, be provided with lower transverse beam, described lower transverse beam is connected with lower hydraulic cylinder, described frame construction is flexible by lower hydraulic cylinder, adjust the angle of fore-and-aft direction, such technical scheme has solved common suspender cannot complete the problem that beam section attitude is adjusted, thereby guaranteed the installation accuracy of beam section, greatly reduced beam section and adjusted the time used, improved operating efficiency.
As preferably, the suspender that described fixed boom hangs can be walked on longeron, thereby reaches the object that two ends all can be lifted by crane.
As preferably, the suspender that described fixed boom hangs can be thrown off with the lifting appliance of cantilever crane, so that bridge parts is anchored at for a long time, specifies fixed position, meets the requirement of construction technology.
As preferably, the upper hydraulic cylinder of described suspender becomes miter angle to be connected with V-type movable part, and the other end is connected with top rail.
As preferably, under described suspender, hydraulic cylinder becomes miter angle to be connected with lower transverse beam, and the other end is connected with top rail.
The beneficial effect the utlity model has: by hanger structure being made into hinged two parts up and down, and install hydraulic cylinder additional between upper and lower two parts, suspender aloft can be adjusted the attitude of beam section, solve common suspender and cannot complete the problem that beam section attitude is adjusted, thereby guaranteed the installation accuracy of beam section, greatly reduce beam section and adjusted the time used, improved operating efficiency.Therefore the utlity model has the features such as simple in structure, reasonable in design.

The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: a kind of fixed boom hangs, as depicted in figs. 1 and 2, comprise suspender, trolley and longeron, described suspender is comprised of suspension rod and the V-type movable part being arranged on suspension rod, as shown in Figure 3 and Figure 4, described V-type movable part connects upper hydraulic cylinder, and described upper hydraulic cylinder is connected with top rail, described top rail is flexible by upper hydraulic cylinder, adjusts the angle of left and right directions; Described top rail is connected with frame construction, and described top rail is directly over frame construction; In the middle of described frame construction, be provided with lower transverse beam, described lower transverse beam is connected with lower hydraulic cylinder, described frame construction is flexible by lower hydraulic cylinder, adjust the angle of fore-and-aft direction, such technical scheme has solved common suspender cannot complete the problem that beam section attitude is adjusted, thereby guaranteed the installation accuracy of beam section, greatly reduced beam section and adjusted the time used, improved operating efficiency.
During work, beam section is fixed on to the bottom of suspender, cantilever crane rises to installation site by travelling car by beam section, by instrument or visually observe bridge parts and the setting angle on body of a bridge basis whether correct, as incorrect, by upper hydraulic cylinder and the lower hydraulic cylinder of suspender, adjust respectively left and right directions and the fore-and-aft direction of bridge parts, when the angle adjustment of bridge parts correct, by trolley and longeron, bridge parts is winched to installation site again, such technical scheme has solved common suspender cannot complete the problem that beam section attitude is adjusted, thereby guaranteed the installation accuracy of beam section, greatly reduce beam section and adjusted the time used, improved operating efficiency.
Finally, it should be pointed out that above embodiment is only the more representational example of the utility model.Obviously, the utility model is not limited to above-described embodiment, can also have many distortion.Any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all should think and belong to protection domain of the present utility model.
