Abstract
The utility model provides a single -boom portal slewing crane's amplitude changing device, including amplitude changing device, amplitude changing device include gear and rack, still include crane boom and become a width of cloth arm, the gear setting on becoming width of cloth arm, fixed the setting in crane boom of rack, change width of cloth arm and crane boom between through a plurality of pulley sliding fit, the movable fit of wheel and rack tooth, still including the motor that drives gear revolve, the gear can drive and become width of cloth arm along a rack extending direction back and forth movement. The single -boom portal slewing crane's amplitude changing device that this product provided has solved and has taken place the problem that wire rope drops when the hoist in the existing market becomes the width of cloth easily, the utility model discloses take the drive of rack and pinion or screw rod to become the width of cloth, stability is good, can not meet accident, and is very safe.
Description
Technical field
This utility model is related to a kind of jib lubbing mechanism of crane, more particularly to a kind of luffing of single-cantilever-crane gantry crane
Mechanism.
Background technology
Single-cantilever-crane gantry crane in the market, luffing are all using rope pulley structure, as steel wire rope is soft
Property rope, and steel wire rope quantity is more, as the minimum radiuses of arm support reduce as the arm support elevation angle increases, when speed it is too high
When, wind increases, inertia force are also increased, and at this moment steel wire rope loses easily out of control, it may appear that dangerous, so needing a kind of single arm support
The jib lubbing mechanism of gantry crane could solve these problems.
Utility model content
For existing technical deficiency, this utility model provides a kind of jib lubbing mechanism of single-cantilever-crane gantry crane.
To achieve these goals, technical solution adopted in the utility model is：A kind of single-cantilever-crane gantry crane
Jib lubbing mechanism, including jib lubbing mechanism, described jib lubbing mechanism include gear and tooth bar, also including crane arm support and luffing jib,
Described gear is arranged in luffing jib, and described tooth bar is fixedly installed in crane arm support, described luffing jib and lifting
It is slidably matched by some pulleys between horn frame, described wheel and rack tooth is dynamic to be coordinated, also including drive pinion rotation
Motor, described gear can drive luffing jib to move back and forth along tooth bar bearing of trend.
A kind of jib lubbing mechanism of single-cantilever-crane gantry crane, including jib lubbing mechanism, described jib lubbing mechanism include screw rod and
Screw sleeve, also including crane arm support and luffing jib, described screw rod is arranged in crane arm support, and described screw sleeve is fixed
Be arranged in luffing jib, be slidably matched by some pulleys between described luffing jib and crane arm support, described screw rod with
Screw sleeve screw-driven coordinates, and also including the motor for driving screw rod to rotate, described screw rod can drive luffing jib along screw axis
Bearing of trend is moved back and forth.
The beneficial effects of the utility model：The jib lubbing mechanism of the single-cantilever-crane gantry crane that this product is provided is solved at present
The problem that steel wire rope comes off is susceptible to during crane amplitude variation on market, this utility model takes rack-and-pinion or screw drive
Luffing, good stability will not occur accident, very safe.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
As shown in figure 1, a kind of jib lubbing mechanism of single-cantilever-crane gantry crane, including jib lubbing mechanism, described jib lubbing mechanism
Including gear 1 and tooth bar 2, also including crane arm support 3 and luffing jib 4, described gear 1 is arranged in luffing jib 4, described
Tooth bar 2 is fixedly installed in crane arm support 3, is slided by some pulleys and match somebody with somebody between described luffing jib 4 and crane arm support 3
Close, described gear 1 is dynamic with 2 tooth of tooth bar to be coordinated, and also includes the motor rotated with moving gear 1, and described gear 1 can drive luffing
Arm 4 is moved back and forth along 2 bearing of trend of tooth bar.
A kind of jib lubbing mechanism of single-cantilever-crane gantry crane, including jib lubbing mechanism, described jib lubbing mechanism include screw rod and
Screw sleeve, also including crane arm support 3 and luffing jib 4, described screw rod is arranged in crane arm support 3, described screw sleeve
It is fixedly installed in luffing jib 4, is slidably matched by some pulleys between described luffing jib 4 and crane arm support 3, it is described
Screw rod is coordinated with screw sleeve screw-driven, and also including the motor for driving screw rod to rotate, described screw rod can drive luffing jib 4 along spiral shell
Rod axis bearing of trend is moved back and forth.
The beneficial effects of the utility model：The jib lubbing mechanism of the single-cantilever-crane gantry crane that this product is provided is solved at present
The problem that steel wire rope comes off is susceptible to during crane amplitude variation on market, this utility model takes rack-and-pinion or screw drive
Luffing, good stability will not occur accident, very safe.
