Abstract
The utility model discloses a heavy-duty low-speed rack test unit, which comprises a fixing frame. A first chute and a second chute parallel to each other and provided with a proper spacing are arranged on the fixing frame, a first hydraulic cylinder and a second hydraulic cylinder respectively driving a first rack and a second rack to reciprocate on the first chute and the second chute are further arranged on the fixing frame, a gear matched with the first rack and the second rack is further rotationally installed between the first chute and the second chute, and one-way back pressure valves are disposed at oil openings of the first hydraulic cylinder and the second hydraulic cylinder.
Description
Technical field
The utility model relates to a kind of test step, particularly a kind of heavy-duty low-speed tooth bar test unit.
Background technology
Self-elevating drilling platform is to use at present very wide offshore drilling unit, is characterized in utilizing the landing of spud leg implementation platform that can lifting.Have both at home and abroad on a lot of old self-elevating platform (SEP) spud legs tooth bar experience wear, damage very seriously, have a strong impact on the job safety of platform.
In order to guarantee the platform good working order, the shipowner who has at present adopts the scheme of changing all tooth bars of platform, and a lot of shipowners consider from economic aspect, just the part of former tooth bar damage are repaired or are changed.These two kinds of schemes all need tooth bar is carried out heavy-duty test, verify that its life-span reaches and the matching of the former jacking system gear of platform.
For the test of this low-speed heave-load tooth bar, the mode that generally adopts big motor to rotate on tooth bar by big wheel box driven gear, its shortcoming are the complex structures of pilot system, the cost height of input.
The utility model content
At the problem that prior art exists, the purpose of this utility model is to provide a kind of heavy-duty low-speed tooth bar test unit simple in structure.
A kind of heavy-duty low-speed tooth bar test unit of the present utility model comprises: fixed frame, this fixed frame are provided with first slideway and second slideway of two suitable spacings that are parallel to each other and have; Also be provided with second hydraulic cylinder that driving first tooth bar moves back and forth on second slideway at first hydraulic cylinder that moves back and forth on first slideway and driving second tooth bar on the described fixed frame; Also rotatable being equipped with and first tooth bar and the suitable gear of second tooth bar between first slideway and second slideway; Hydraulic fluid port at described first hydraulic cylinder and second hydraulic cylinder also is provided with unidirectional counterbalance valve.
The contactor of described first tooth bar of control and the second tooth bar shift motion preferably, also is installed on described fixed frame.
The utility model drives first tooth bar respectively by first hydraulic cylinder and second hydraulic cylinder and second tooth bar moves back and forth on slideway, and cooperates unidirectional counterbalance valve, can finish the heavy duty experiment of tooth bar well.In addition, the utility model also has simple in structure, compact, characteristics such as low cost of manufacture.
Description of drawings
Fig. 1 is the front view of heavy-duty low-speed tooth bar test unit.
Embodiment
Below in conjunction with Figure of description the utility model is further described.
As shown in Figure 1, the utility model comprises: fixed frame 1, fixed frame 1 are provided with first slideway 11 and second slideway 12 of two suitable spacings that are parallel to each other and have; Also be provided with second hydraulic cylinder 6 that driving first tooth bar 3 moves back and forth on second slideway 12 at first hydraulic cylinder 5 that moves back and forth on first slideway 11 and driving second tooth bar 4 on the fixed frame 1.Also rotatable being equipped with and first tooth bar 3 and the suitable gear 2 of second tooth bar 4 between first slideway 11 and second slideway 12; Hydraulic fluid port at first hydraulic cylinder 5 is provided with unidirectional counterbalance valve 7, is provided with unidirectional counterbalance valve 8 at the hydraulic fluid port of second hydraulic cylinder.In addition, the contactor 9 of control first tooth bar 3 shift motions and the contactor 10 of second tooth bar, 4 shift motions also are installed on fixed frame 1.
When the utility model used, first hydraulic cylinder 5 promoted first tooth bar 3 when first slideway 11 of fixed frame 1 moves, and first tooth bar 3 promotes gears 2 and rotates, and gear 2 drives second tooth bar 4 again and moves on second slideway 12.By the back pressure of unidirectional counterbalance valve 8 is set, the resistance of motion that second tooth bar 4 of scalable is subjected to makes it to reach the test load requirement.In addition, can play the action of controlled hydraulic system reversal valve by contactor 9,10, it is mobile to control moving in circles of first tooth bar 3 and second tooth bar 4, reaches the tooth bar test objective.
Claims (2)
1. a heavy-duty low-speed tooth bar test unit is characterized in that, comprising: fixed frame, this fixed frame are provided with first slideway and second slideway of two suitable spacings that are parallel to each other and have; Also be provided with second hydraulic cylinder that driving first tooth bar moves back and forth on second slideway at first hydraulic cylinder that moves back and forth on first slideway and driving second tooth bar on the described fixed frame; Also rotatable being equipped with and first tooth bar and the suitable gear of second tooth bar between first slideway and second slideway; Hydraulic fluid port at described first hydraulic cylinder and second hydraulic cylinder also is provided with unidirectional counterbalance valve.
2. a kind of heavy-duty low-speed tooth bar test unit as claimed in claim 1 is characterized in that, the contactor of described first tooth bar of control and the second tooth bar shift motion also is installed on described fixed frame.
