Abstract
The invention relates to a lifting system of a lifting type platform, in particular to an axial limiting structure of a main gear shaft of the lifting system. The axial limiting structure comprises the main gear shaft, a pile box and a limiting structure, wherein the limiting structure is arranged at the end of the main gear shaft. The axial limiting structure solves the problem of difficult traditional assembling, maintaining and the like, is reasonable and compact in structure, convenient, stable and reliable to use, can achieve fast mounting and demounting of the main gear shaft and improves the working efficiency.
Description
Technical field
The present invention relates to the elevating system of elevating platform, be specifically related to a kind of elevating system main gear shaft axial limiting structure.
Background technique
Elevating platform is a kind of mobile ocean engineering platform for marine energy sources exploitation and prospecting, and its chief component is working platform, the elevating system of the spud leg of support platform, control workbench lifting and the fastening system behind the working platform location.
The main gear shaft of elevating system is subjected to the effect of external force can produce axial runout in the process of lifting platform.In order to guarantee system stable operation, adopt limit stoper that main gear shaft is carried out axial limiting.Traditional axial limiting structure as shown in Figure 1, plain bearing housing 5 flutings at main gear shaft 1 middle part, have the limit stoper 3 of mounting hole to be stuck in the groove design, by bolt 2 limit stoper 3 and stake case 4 are connected firmly, wherein plain bearing housing 5 and main gear shaft 1 connect firmly.In such structure, limit stoper 3 is at the middle part of main gear shaft 1 and stake case 4, and the staff is difficult to operation, and this assembling and dismounting to main gear shaft 1 has brought very big inconvenience, is unfavorable for the maintaining of system.
Summary of the invention
Problem at prior art exists provides a kind of elevating system main gear shaft axial limiting structure.
The technical solution used in the present invention is:
A kind of elevating system main gear shaft axial limiting structure comprises main gear shaft, stake case and limit stoper, and described limit stoper is arranged on the end of described main gear shaft.
As preferred implementation of the present invention, the end of described main gear shaft is provided with groove, and described limit stoper is arranged in the described groove.
As preferred implementation of the present invention, described limit stoper and described stake case are fixed together.An end that is described limit stoper is arranged in the described groove of described master gear end, and the other end of described limit stoper and described stake case are fixed together to play the effect spacing to main gear shaft.
As preferred implementation of the present invention, also comprise bolt, by described bolt described limit stoper is fixedly connected on the described stake case.
As preferred implementation of the present invention, also comprise gland, by described bolt described gland is fixedly connected on the described stake case with described limit stoper.
In sum, owing to adopted technique scheme, the invention has the beneficial effects as follows:
1, problems such as traditional assembling, maintaining difficulty have been solved.
2, rational in infrastructure, compact, easy to use, stable, reliable.
3, can realize the fast assembling-disassembling of main gear shaft, improve working efficiency.
