Abstract
The utility model discloses a gap adjustment device which comprises a guide holder. A guide piston and a guide wheel are arranged in the guide holder. The guide piston and the guide wheel are interconnected. The guide wheel is connected with a steel pile guide sleeve of a steel pile. An adjusting screw is fixedly arranged at the front end of the guide holder. Compared with the prior art, the gap adjustment device is arranged on the meshing position of a gear and a rack which are corresponding to the position between the steel pile and the steel pile guide sleeve, the guide wheel contacts the steel pile, the guide wheel can roll along the linear motion of the steel pile, even if under working condition of walking and ship moving, the steel pile falls and tilts 30 degrees, one face with the rack of the steel pile is correctly meshed to the gear, and therefor the friction force between the steel pile and the gear,and friction loss of the guide wheel is small. The gap adjustment device is applicable to a heavy lifting steel pile, safety and economical efficiency are both well improved and the purpose of the gap adjustment device is achieved.
Description
Technical field
The utility model relates to the adjustment of a kind of gap, particularly a kind ofly is applicable to the lash adjusting device that ocean platform or other heavy machineries need descending operation.
Background technique
Lash adjusting device mainly is the displacement gap when adjusting the piling bar mechanism kinematic, and flank engagement is normal at the volley to make the gear driven tooth bar.
In the prior art, lash adjusting device adopts guide sleeve by limiting stopper constrained motion part movement clearance, the lash adjusting device of this form be used for little Section-steel Piles and connecting rod spacing more, adjust gap with piling bar or connecting rod by the position of bolt restriction limiting stopper.
Above-mentioned lash adjusting device is applicable to piling bar or linkage mechanism, and weight is lighter, and the required precision that the gap is adjusted is lower; And, during work frictional loss large, be not suitable for large-scale piling bar elevator mechanism.
Therefore, need especially a kind of lash adjusting device, to solve the above-mentioned existing problem that exists.
The model utility content
The purpose of this utility model is to provide a kind of lash adjusting device, for the deficiencies in the prior art, guarantees that piling bar can slip teeth in movement process and damage gear, tooth bar and affect the lifting of piling bar.
The technical problem that the utility model solves can realize by the following technical solutions:
A kind of lash adjusting device is characterized in that, it comprises a guide holder, be provided with guide piston and upper saw pulley in the described guide holder, described guide piston and upper saw pulley are connected to each other, and described upper saw pulley is connected with the piling bar guide sleeve of piling bar, and the front end of described guide holder is fixed with the adjustment screw rod.
In an embodiment of the present utility model, described adjustment screw rod is fixed on the described guide holder by an acorn nut.
In an embodiment of the present utility model, the fixed end of described guide piston is arranged on the adjustment screw rod side on the described guide holder, and the movable end of described guide piston is connected with described upper saw pulley.
Lash adjusting device of the present utility model, compared with prior art, described lash adjusting device is arranged on corresponding teeth wheel and rack engagement place between piling bar and the piling bar guide sleeve, use upper saw pulley to contact with piling bar, upper saw pulley can roll with the piling bar straight line motion, fall tilt 30 ° state of stake even move boatman's condition piling bar in walking, also can make the one side and gear correct engagement of piling bar band tooth bar, can reduce and piling bar between frictional force, and the loss of upper saw pulley self friction is little, can be used for heavy lifting piling bar, Security and Economy are all well improved, and realize the purpose of this utility model.
Characteristics of the present utility model can be consulted the detailed description of the graphic and following better mode of execution of this case and be obtained to be well understood to.
Description of drawings
Fig. 1 is the structural representation of lash adjusting device of the present utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, lash adjusting device of the present utility model, it comprises a guide holder 100, be provided with guide piston 200 and upper saw pulley 300 in the described guide holder 100, described guide piston 200 and upper saw pulley 300 are connected to each other, described upper saw pulley 300 is connected with the piling bar guide sleeve 11 of piling bar 10, and the front end of described guide holder 100 is fixed with adjusts screw rod 400.
In the utility model, described adjustment screw rod 400 is fixed on the described guide holder 100 by an acorn nut 500.
In the utility model, the fixed end of described guide piston 200 is arranged on adjustment screw rod 400 sides on the described guide holder 100, and the movable end of described guide piston 200 is connected with described upper saw pulley 300.
During use, 2 groups of lash adjusting devices of the present utility model are set between piling bar 10 and piling bar guide sleeve 11, corresponding teeth wheel and rack engagement place, use upper saw pulley 300 to contact with piling bar 10, upper saw pulley 300 can roll with piling bar 10 straight line motions, can reduce and piling bar 10 between frictional force, and upper saw pulley 300 self friction losses are little, can be used for heavy lifting piling bar, Security and Economy are all well improved; Fall tilt 30 ° state of stake even move boatman's condition piling bar in walking, also can make the one side and gear correct engagement of piling bar band tooth bar.
At piling bar tooth bar force part opposite side a plurality of (2 groups) lash adjusting device of the present utility model is set, wheel and rack normally is with carry-over bar by the gear that gap adjustment realization motor drives, the engagement of the flank of tooth is normal in the lifting process of realization piling bar.
Lash adjusting device of the present utility model is applied to the wheel and rack gap adjustment of piling bar elevator mechanism, its major function is in the process of elevator mechanism lifting piling bar, adjust tooth bar and transmitting gear engagement distance on the piling bar, thereby guarantee that piling bar can slip teeth in movement process and damage gear and tooth bar, affect the piling bar lifting.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall in claimed the utility model scope, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
