Advantage of the present utility model and effect: simple in structure, compact dimensions, in light weight, buying and use cost is low, maintaining is simple, damageable spare parts is few; Move up and down on tooth bar by direct geared and to finish enhanced feature, the transmission efficiency height; By rack-and-pinion is positive drive, promptly can finish the lifting operation, the operation of also can pressurizeing.
Description of drawings
Fig. 1 is a rack-and-pinion rig schematic side view of the present utility model;
Fig. 2 is a rack-and-pinion rig front elevational schematic of the present utility model;
Fig. 3 is the cross-sectional schematic that rack-and-pinion rig lifting appliance of the present utility model is connected with tooth bar.
Among the figure, 1. derrick, 2. base, 3. drive on the top, 4. gear, 5. reduction box, 6. motor, 7. brake gear, 8. lifting appliance, 9. tooth bar, 10. hook set sensor, 11. left rails, 12. right guide rails, 13. left leading blocks, 14. right leading blocks.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
With reference to Fig. 1, Fig. 2, structure of the present utility model is, on rig substructure 2, be installed with derrick 1, in the middle of derrick 1, vertically be fixed with tooth bar 9, (from the front of derrick 1), the both sides of tooth bar 9 are equipped with teeth, derrick 1 left side front column is fixed with left rail 11, derrick right side front column is fixed with right guide rail 12, tooth bar 9, one cover lifting appliance 8 is installed on left rail 11 and the right guide rail 12, horizontal symmetrical is equipped with paired gear 4 in the lifting appliance 8, reduction box 5, motor 6 (or hydraulic motor), brake gear 7, each reduction box 5 is connected with gear 4 that cover motor 6 and 7, two reduction boxes 5 of brake gear connect by transmission system and is connected with a joggle with the both sides teeth of tooth bar 9 respectively; Be connected with the top in the bottom of lifting appliance 8 and drive 3, be provided with hook set sensor 10 between driving 3 on lifting appliance 8 and top.Omitted the structure of ladder among Fig. 2.
With reference to Fig. 3, the opposite side (right side) that respectively is furnished with the left leading block 13 of a cover, lifting appliance in the side (left side) of lifting appliance 8 up and down respectively is furnished with the right leading block 14 of a cover up and down, and lifting appliance 8 is slidingly connected with the left rail 11 and the right guide rail 12 of derrick respectively by left leading block 13 and right leading block 14.By bolt reduction box 5 is arranged in the lifting appliance 8, reduction box 5 leading portions are equipped with the gear 4 identical with tooth bar 9 moduluses, reduction box 5 afterbodys are equipped with motor 6, and the afterbody of motor 6 is equipped with brake gear 7, simultaneously with motor 6 by being bolted on the lifting appliance 8.Lifting appliance 8 is provided with the gear 4 of 2 covers, 4 covers, 6 covers according to the difference that the rig hook carries.
