Description
Technical Field
The utility model relates to the technical field of travelling crane equipment, in particular to a lifting device for travelling crane maintenance.
Background
The production equipment often need be overhauld in the smoke-box, and because smoke-box equipment is great, all install the driving in the smoke-box usually for jack up production equipment, and use the driving back for a long time, also need overhaul the driving, and the driving need go up and down the driving at the maintenance in-process, makes the driving rise from the track, and there is not concrete instrument to go up and down the driving now, overhauls at every turn all more troublesome, overhauls inefficiency.
Disclosure of Invention
Aiming at the problems in the background art, the utility model provides a lifting device for overhauling a travelling crane, which realizes the lifting of the travelling crane through the lifting device, is convenient for overhauling the travelling crane, improves the overhauling efficiency, and is convenient and quick to use.
In order to realize the purpose, the utility model is realized by the following technical scheme: the crane maintenance lifting device comprises a fixing device, a supporting plate, a screw rod and a circular boss, wherein the fixing device is fixedly connected to both ends of the supporting plate, the screw rod is installed in the middle of the supporting plate through threads, and the circular boss is fixedly installed at the bottom of the screw rod; the fixing device is composed of two upper clamping plates and two side clamping plates, the two upper clamping plates are connected through bolts, and the lower ends of the two upper clamping plates are respectively connected with the side clamping plates through bolts.
Preferably, a backing plate is installed at the top end of the screw rod.
Preferably, four clamping grooves are symmetrically distributed on the circular boss, and the handrail can be inserted into the clamping grooves.
The utility model has the beneficial effects that:

Detailed Description
In order to make the objects, technical solutions and technical effects of the present invention more apparent, the following description of the preferred embodiments of the present invention with reference to the accompanying drawings will be made for the convenience of the skilled in the art.
As shown in fig. 1-3, the lifting device for repairing a traveling crane comprises a fixing device 1, a supporting plate 2, a screw rod 3 and a circular boss 4, wherein both ends of the supporting plate 2 are fixedly connected with the fixing device 1, the supporting plate 2 is fixed on a traveling rail 10 through the fixing device 1, each fixing device 1 is composed of two upper clamping plates 5 and two side clamping plates 6, the two upper clamping plates 5 are connected through bolts, the lower ends of the two upper clamping plates 5 are respectively connected with the side clamping plates 6 through bolts, the two side clamping plates 6 are also connected through bolts, the fixing device 1 is convenient to install and detach, and the two upper clamping plates 5 and the two side clamping plates 6 are matched for use, so that the lifting device can adapt to the traveling rails 10 with different sizes, and is more widely used in a refitting manner. Install lead screw 3 through the screw thread in the middle of backup pad 2, when making lead screw 3 rotate, lead screw 3 reciprocates for backup pad 2, when lead screw 3 moves up, 3 tops of lead screw can push up on driving beam arm 11, and backing plate 7 is installed on 3 tops of lead screw, 3 tops of lead screw have been avoided damaging driving beam arm 11, 3 bottom fixed mounting of lead screw have circular boss 4, be equipped with four draw-in grooves 8 of symmetric distribution on the circular boss 4, can insert handrail 9 in the draw-in groove 8, conveniently rotate circular boss 4 through handrail 9, and then drive lead screw 3 through circular boss 4 and rotate, thereby make lead screw 3 reciprocate.
The working process of the utility model is as follows: fixing device 1 on driving track 10, screwing up the bolt for fixing device 1 can not remove, then rotates circular boss 4 through handrail 9, and lead screw 3 shifts up and withstands driving track 10, continues to rotate circular boss 4, realizes jack-up driving beam arm 11.
Finally, it is noted that the above-mentioned preferred embodiments illustrate rather than limit the utility model, and that, although the utility model has been described in detail with reference to the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the scope of the utility model as defined by the appended claims.
