Abstract
The utility model relates to a dual-rotation power box of a rotary drilling rig. The dual-rotation power box comprises a rack and a transmission box, a power head, an upper rotary device and a lower rotary device, which are respectively installed on the rack, wherein the power head is arranged below the transmission box and is fixedly connected with a pivot shaft, and the upper rotary device and the lower rotary device respectively abut against the pivot shaft and drive the pivot shaft to ascend and descend. Due to the arrangement of the upper rotary device and the lower rotary device, the axial pressing points of the power head are increased, overlarge axial pressure can be prevented from being applied to the power head, and the service life of the power head can be prolonged.
Description
[technical field]
The utility model relates to a kind of building block of rotary drilling rig, is specifically related to a kind of two rotary motive power casees of rotary drilling rig, belongs to technical field of engineering machinery.
[background technology]
Rotary drilling rig has plurality of advantages such as efficiency of construction height, flexible and convenient operation and hole quality are good, has become the main construction machinery that pile tube is built.
The rotary motive power case is a vitals of rotary drilling rig.Yet two rotary motive power casees of the rotary drilling rig of prior art only provide single rotary motive power usually, cause the axial compression of unit head excessive easily, shorten the application life of equipment.
For solving the problems of the technologies described above, necessary a kind of two rotary motive power casees with the rotary drilling rig that improves structure are provided, to overcome said defective of the prior art.
[utility model content]
For addressing the above problem, the purpose of the utility model is to provide a kind of two rotary motive power casees of rotary drilling rig of simple in structure, long service life.
For realizing above-mentioned purpose, the technical scheme that the utility model is taked is: a kind of two rotary motive power casees of rotary drilling rig, and it comprises frame and the rack-mounted transmission case of difference, unit head, goes up slewing equipment and turning down device; Wherein, said unit head is installed on the below of transmission case, and it is fixed with a pivot, and said upward slewing equipment and turning down device connect with pivot respectively and drive the pivot oscilaltion.
Two rotary motive power casees of the rotary drilling rig of the utility model further are set to: it further is provided with a buffer, and this buffer is positioned at the top of slewing equipment.
Compared with prior art; The utlity model has following beneficial effect: two rotary motive power casees of the rotary drilling rig of the utility model are through being provided with slewing equipment and turning down device; Increased the axial pressure point of unit head; Can prevent effectively that like this unit head receives axial pressure excessive, improve the application life of unit head.
[description of drawings]
Fig. 1 is the structural representation of two rotary motive power casees of the rotary drilling rig of the utility model.
[specific embodiment]
See also shown in the Figure of description 1, the utility model is a kind of two rotary motive power casees of rotary drilling rig, and it is by frame 1 and be installed in transmission case 2 on the frame 1, unit head 3 respectively, go up component-assembled such as slewing equipment 4 and turning down device 5 forms.
Wherein, said unit head 3 is installed on the below of transmission case 2, and it is fixed with a pivot 31, thereby drives unit head 3 work.
Said transmission case 2 is for the operation of equipment provides the power support, and it can adopt hydraulic power system.
Said upward slewing equipment 4 connects with pivot 31 respectively with turning down device 5 and drives pivot 31 oscilaltions.And should go up slewing equipment 4 and turning down device 5 independent actions on pivot 31, thereby can adjust the axial pressure point of unit head 3, can prevent effectively like this that unit head 3 received axial pressure excessive, improve the application life of unit head 3.
Two rotary motive power casees of the rotary drilling rig of the utility model also are provided with a buffer 6, and this buffer 6 is positioned at the top of slewing equipment 4, and it plays cushioning effect, prevent that unit head 3 is stressed too quickly and shake bad miscellaneous part.
The above specific embodiment is merely the preferred embodiment of this creation, not in order to limiting this creation, any modification of being made within all spirit and principles in this creation, is equal to replacement, improvement etc., all should be included within the protection domain of this creation.
Claims (2)
1. two rotary motive power casees of a rotary drilling rig is characterized in that: comprise frame and the rack-mounted transmission case of difference, unit head, go up slewing equipment and turning down device; Wherein, said unit head is installed on the below of transmission case, and it is fixed with a pivot, and said upward slewing equipment and turning down device connect with pivot respectively and drive the pivot oscilaltion.
2. two rotary motive power casees of rotary drilling rig as claimed in claim 1, it is characterized in that: it further is provided with a buffer, and this buffer is positioned at the top of slewing equipment.
