Preferably, described length adjustment device comprises a sleeve, and the two ends of sleeve are provided with two sections internal threads that rotation direction is opposite, and described two sections internal threads are threaded with upper support bar and lower support bar respectively.
Preferably, there is rotation hand wheel described sleeve outside, and sleeve is fixedly connected with rotation hand wheel.
Preferably, described sleeve is provided with a plurality of pin holes, is provided with steady brace in the pin hole.
Preferably, described permanent seat be a block welding at the retaining plate of lower support bar lower end, retaining plate is provided with bolt hole.
Preferably, the angle of described retaining plate and lower support bar axis is acute angle.
Preferably, the upper end of described upper support bar is welded with strongback, and strongback and retaining plate are perpendicular.
As mentioned above, rotary drum maintenance fixing support rack of the present utility model, has following beneficial effect: when rotary drum overhauls, only need this device is placed on the appropriate location, then permanent seat is fixed on the worktable, the lower end of support bar is fixedly connected with permanent seat, and the upper end of support bar is supported on the rotary drum.This device has not only solved the problem that the time is long, workman's workload large, safety coefficient is not high of rotary drum upkeep operation, and make simple, easy to use, cost is low.

Embodiment
The structure that Figure of description illustrates, ratio, size etc., equal contents in order to cooperate specification sheets to disclose only, equal contents in order to cooperate specification sheets to disclose only, understand and reading for person skilled in the art scholar, be not to limit the enforceable qualifications of the present invention, therefore the technical essential meaning of tool not, the adjustment of the modification of any structure, the change of proportionlity or size, do not affecting under the effect that the utility model can produce and the purpose that can reach, all should still drop on the technology contents that the utility model discloses and get in the scope that can contain.Simultaneously, quote in this specification sheets as " on ", the term such as D score, 'fornt', 'back', " centre ", also only for ease of understanding of narrating, but not in order to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, under without essence change technology contents, when also being considered as the enforceable category of the utility model.
As shown in Figure 1, the utility model rotary drum maintenance fixing support rack comprises support bar 1 and permanent seat 9, and described permanent seat 9 is fixedly connected on the lower end of support bar 1.Support bar 1 is divided into two sections, comprises upper support bar 4 and lower support bar 3, and upper support bar 4 is connected bar by length adjustment device 2 connections with lower support.Described length adjustment device 2 can adopt hydraulic efficiency system, also can adopt the devices such as screw block that the length of support bar 1 is regulated.This installs preferred length adjustment device 2 and comprises a sleeve 5, and the two ends of sleeve 5 are provided with two sections internal threads that rotation direction is opposite.Described two sections internal threads are threaded with upper support bar 4 and lower support bar 3 respectively.Described sleeve 5 is relatively thicker, and to guarantee support strength, upper support bar 4 and lower support bar 3 can be two sections round iron rods, convenient like this processing.
As shown in Figures 2 and 3, there is rotation hand wheel 6 described sleeve 5 outsides, and sleeve 5 is fixedly connected with rotation hand wheel 6.In addition, also be provided with a plurality of pin holes 10 on the sleeve 5, be provided with steady brace 11 in the pin hole 10, the effect of steady brace 11 is that the overall length at upper support bar 4 and lower support bar 3 reaches work and takes, and makes upper support bar 4 and lower support bar 3 fastening to finish service work with sleeve 5.Because steady brace 11 is to play positioning action, so the pitch of support bar 1 and sleeve 5 is larger, makes things convenient for upper support bar 4 and lower support bar 3 fastening with sleeve 5, and can also improve like this intensity of device.
The upper end of described upper support bar 1 is welded with strongback 8, and strongback 8 is perpendicular with retaining plate 7.Strongback 8 connects rotary drum 12 when installing, and accidentally injures the maintainer to guarantee the situation that support bar 1 and rotary drum 12 can not occur becoming flexible.
