Description
Technical field
The utility model relates to a kind of high pedestal jib crane break seal arrangement, particularly a kind of seal closure that high pedestal jib crane walking inertia brake is sealed of being applicable to.
Background technique
At present, gantry crane is indispensable crane gear in harbour service, has mainly been responsible for the handling task of harbour goods and shipping container etc.Yet the operation field at gantry crane, owing to there being the foreign material such as a large amount of dusts, ore in sand form, and and easily by wind, blown brake shoe into the walking inertia brake of gantry crane, each bearing pin hinge etc. and locate, thereby can cause this position corrosion, clamping stagnation, affect lubrication effect, so that the walking inertia brake of gantry crane opens and closes not smooth.And there is no at present effective method, ore in sand form, dust and other impurities and door machine inertia brake are effectively isolated and guaranteed that inertia brake switching is smooth and easy, flexible, effective simultaneously.
Model utility content
Technical assignment of the present utility model is for above the deficiencies in the prior art, and a kind of seal closure that high pedestal jib crane walking inertia brake is sealed of being applicable to is provided.
The technical scheme in the invention for solving the technical problem is: a kind of high pedestal jib crane inertia brake dust-proof sealing device, it is characterized in that: comprise base support, sealing cover and end cap, described base support comprises base plate, chute board and riser, two described chute boards are fixedly mounted between two base plates, on described base plate, riser is installed, described chute board is provided with slideway; Two chute board tops of described base support are provided with two sealing covers, and top board is stamped in described sealing and three sidewalls form, and the lower end of the two side of two described sealing covers is embedded in the slideway of chute board; The top board of described sealing cover is provided with long strip breach without a side of sidewall; Between described riser and sealing cover, be installed with spring; The base plate of described base support is provided with through hole; One end of the both sides of end cap and two risers is hinged; One end of described end cap is provided with handle, and described end cap covers on the top of walking inertia brake and sealing cover.
The lower end of above-mentioned sealing cover two side is provided with roller.
Compared with prior art, the utlity model has following outstanding beneficial effect:
1, this device solved the inertia brake of high pedestal jib crane brake shoe pivot pin clamping stagnation, get rusty, open and close the phenomenons such as not smooth, guaranteed again that inertia brake opens and closes smooth and easy, flexible, effective simultaneously;
2, this device has dustproof end cap, when not using high pedestal jib crane, can cover on the top of the walking inertia brake of high pedestal jib crane, makes sealing effect more obvious;
3, this device is fixedly connected with the fixed hole of the inertia brake base of high pedestal jib crane by bolt, convenient disassembly, is easy to install.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of sealing cover in Fig. 1.
Embodiment
Below in conjunction with specification drawings and specific embodiments, the utility model is further illustrated.
As shown in Figure 1, the utility model comprises base support 8, sealing cover 4 and end cap 11.
Described base support 8 comprises base plate 9, chute board 5 and riser 2.Two described chute boards 5 are fixedly mounted between two base plates 9, on described base plate 9, riser 2 are installed.Described chute board 5 is provided with slideway.
Two chute board 5 tops of described base support 8 are provided with two sealing covers 4, and described sealing cover 4 is comprised of top board and three sidewalls, and the lower end of the two side of two described sealing covers 4 is embedded in the slideway of chute board 5.In optimized project, as shown in Figure 2, the lower end of described sealing cover 4 two sides is provided with roller 13, can make like this sealing cover 4 more easily slide in the slideway of chute board 5.The top board of described sealing cover 4 is provided with long strip breach without a side of sidewall, and the through hole that the curved bar 6 of high pedestal jib crane walking inertia brake forms through the long strip breach on two sealing covers 4 is connected with pedal brake plate 7.
Between described riser 2 and sealing cover 4, be installed with spring 3.The base plate 9 of described base support 8 is provided with through hole, and bolt 10 is fixedly connected with base support 8 through the through hole on base plate 9 with the inertia brake base of high pedestal jib crane.
One end of the both sides of end cap 11 and two risers is hinged.One end of described end cap 11 is provided with handle 12, makes the opening and closing of end cap 11 convenient.Described end cap 11 covers on the top of walking inertia brake and sealing cover 4, opens the proper motion stroke that Shi Buhui interferes with high pedestal jib crane walking inertia brake.In the time need to using the walking inertia brake of high pedestal jib crane, end cap 11 is opened, be placed on a side of base support 8, when not using the walking inertia brake of high pedestal jib crane, end cap 11 is covered on to the top of break, this can carry out double-layer seal to walking inertia brake, has greatly guaranteed sealing effect.
Operating process is as follows: the base support of this device 8 is fixed together by bolt 10 and the inertia brake base of high pedestal jib crane.Make two sealing covers 4 cover on a place, the gap that machine inertia brake exposes, end cap 11 is covered on to the top of walking inertia brake and sealing cover 4.When using walking inertia brake, end cap 11 is opened, step on pedal brake plate 7, curved bar 6 moves, when curved bar 6 touches sealing cover 4, two sealing cover 4 also start to move along slideway, due to the effect of spring 3, two sealing covers 4 are close contact relatively all the time, and can not expose gap.After unclamping pedal brake plate 7, due to the effect of spring 3, when the curved bar 6 of inertia brake recovers position, sealing cover 4 returns to original position equally equally.After using, end cap 11 is covered back to original position again.In whole process, the gap of high pedestal jib crane inertia brake can not be exposed in working environment, thereby does not have dust, the foreign material such as ore in sand form are located by the enter brake shoe, each bearing pin hinge etc. of machine walking inertia brake of wind.Can solve like this high pedestal jib crane inertia brake brake shoe pivot pin clamping stagnation, get rusty, open and close the phenomenons such as not smooth, can guarantee that again inertia brake opens and closes smooth and easy, flexible, effective.
It should be noted that; particular of the present utility model have been described in detail the utility model; for a person skilled in the art, the various apparent change of in the situation that not deviating from spirit and scope of the present utility model, it being carried out is all within protection domain of the present utility model.
