Abstract
The utility model relates to a follow-up-free power device of a rotary drilling rig. The power device comprises a rack as well as a transmission case, a drill stem, a power head and a lengthened transmission sleeve which are respectively installed on the rack, wherein the drill stem is vertically arranged and is connected with the transmission case and the power head respectively; the power head is arranged below the transmission case; and the lengthened transmission sleeve is sleeved on the drill stem and passes through the transmission case. The power device has the following beneficial effects: the lengthened transmission sleeve is sleeved on the drill stem, so the drill stem verticality can be effectively positioned, complete machine swing caused by drill stem shock can be prevented and the working stability of a complete machine can be greatly improved.
Description
[technical field]
The utility model relates to a kind of component devices of rotary drilling rig, is specifically related to a kind of no servo-actuated power set 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.
Present rotary drilling rig because of the drilling rod of rig causes vibrations when hard stratum or stone layer impact easily receiving, and then the swing that produces complete machine, makes the complete machine job insecurity in job engineering.
For solving the problems of the technologies described above, necessary a kind of no servo-actuated power set 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, it is a kind of stable that the purpose of the utility model is to provide, and the no servo-actuated power set of the rotary drilling rig that can effectively locate drilling rod.
For realizing above-mentioned purpose, the technical scheme that the utility model is taked is: a kind of no servo-actuated power set of rotary drilling rig, and it comprises frame and the rack-mounted transmission case of difference, drilling rod, unit head and extended type drive sleeve; Wherein, said drilling rod is vertical setting, and it connects transmission case and unit head respectively; Said unit head is positioned at the transmission case below; Said extended type drive sleeve is set on the drilling rod, and it passes said transmission case.
The no servo-actuated power set of the rotary drilling rig of the utility model further are set to: it further comprises a buffer, and this buffer is connected to the drilling rod top.
Compared with prior art; The utlity model has following beneficial effect: the no servo-actuated power set of the rotary drilling rig of the utility model are through a sheathed extended type drive sleeve on drilling rod; Therefore; Can effectively locate the drilling rod verticality, prevent to swing, improve the stability of complete machine work greatly because of the complete machine that the drilling rod vibrations produce.
[description of drawings]
Fig. 1 is the structural representation of no servo-actuated power set 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 no servo-actuated power set of rotary drilling rig, and it is formed by frame 1 and the component-assembled such as transmission case 2, drilling rod 3, unit head 4 and extended type drive sleeve 5 that are installed in respectively on the frame 1.
Wherein, said drilling rod 3 is vertical setting, and it connects transmission case 2 and unit head 4 respectively.Said transmission case 2 is for the operation of equipment provides the power support, and it can adopt hydraulic power system.
Said unit head 4 is positioned at transmission case 2 belows, and this transmission case 2 drives unit head 4 motions through drilling rod 3.
The no servo-actuated power set greatest improvement part of the rotary drilling rig of the utility model is: said extended type drive sleeve 5 is set on the drilling rod 3, and it passes said transmission case 2.This extended type drive sleeve 5 can effectively be located drilling rod 3 verticality, prevents to swing because of the complete machine that the drilling rod vibrations produce, and improves the stability of complete machine work greatly.
The no servo-actuated power set of the rotary drilling rig of the utility model further comprise a buffer 6, and this buffer 6 is connected to the top of drilling rod 3, and it can eliminate the impact of 3 pairs of unit heads 4 of drilling rod effectively.
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.
