Abstract
The utility model provides a dig rig unit head driving motor protector soon which characterized in that: the device comprises a protective cover connected with ear plates, supports and brackets which are arranged on a power head side frame and a sliding frame in a bilateral symmetry way through matched bolt groups; an installation and maintenance window matched with the installation position of a hydraulic motor connected in series with the driving motor is arranged on the protective cover, and an end cover for sealing the window is packaged at the window through a bolt assembly; the inner side surface of the shield is fixedly connected with a reinforcing rib and a rib plate. The utility model discloses a what drive directly to the motor digs the subassembly of rig unit head assembly soon constitutes and optimizes, makes the unit head that the motor directly drives on guaranteeing not to influence normal work, newly-increased subassembly easy dismounting reliably etc. basis, realizes reducing the time of driving motor trouble and the shutdown shut down that leads to external factor to the minimum, improves the purpose of operating efficiency to a certain extent.
Description
Technical Field
The utility model relates to an engineering machine tool field specifically says so and relates to a dig rig unit head driving motor protector soon.
Background
In the prior art, a main stream rotary drilling rig is provided with a motor directly driving a power head, and no protective device such as a protective cover, a protective rod or a mudguard is arranged in front of or above the motor. The risk that rainwater and sewage enter the motor junction box to cause faults, and small-volume soil and stones brought out in the lifting process of the drill rod splash and fall to damage the motor junction box or the appearance and the like exists. The purposes that the failure rate of the power head driving motor caused by external factors is reduced to the minimum and the shutdown time caused by failure is shortened to the minimum in the normal working life period cannot be achieved.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a dig rig unit head driving motor protector soon just to the weak point that exists among the above-mentioned prior art. The utility model discloses a protector is on the basis of the rig unit head assembly is dug soon that the motor directly drives, constitutes to optimize its subassembly, digs rig unit head driving motor protector through the increase and realizes the multiple safeguard function to driving motor soon, if prevent that the rainwater from dipping the terminal box, prevent that little volume stone from splashing damage terminal box or motor housing etc..
The purpose of the utility model can be realized by the following technical measures:
the utility model discloses a protective device for a driving motor of a power head of a rotary drilling rig, which comprises a protective cover connected with lug plates, supports and supports which are arranged on a side frame and a sliding frame of the power head in a bilateral symmetry mode through matched bolt groups; an installation and maintenance window matched with the installation position of the hydraulic motor connected in series with the driving motor is arranged on the protective cover, and an end cover for sealing the window is packaged at the window through a bolt assembly (when the hydraulic motor is required to be connected in series above the power head driving motor, the three end covers installed through the bolt group can be detached, so that the normal installation of the hydraulic motor is ensured); the inner side surface of the shield is fixedly connected with a reinforcing rib and a rib plate.
Compared with the prior art, the utility model discloses following beneficial effect has:
(1) the motor can be effectively prevented from being damaged by rainwater, sewage and small-volume soil and stones due to splashing or smashing, and the fault and shutdown time is reduced;
(2) the structure is reasonable, the dead weight is light, and the influence on the increase of the cost of the structural part and the increase of the dead weight of the whole machine is small;
(3) the bolt combination is suitable in installation position, and the bolt combination is convenient to disassemble when in need of maintenance;
(4) various pipelines connected to the motor are visually shielded, and the motor is neat and attractive;
(5) can meet the installation requirement when the hydraulic motor needs to be connected in series.

Detailed Description
The invention will be further described with reference to the following examples (drawings):
as shown in fig. 1, 3, 6, 8, 11, and 13, the protection device for the driving motor of the power head of the rotary drilling rig of the present invention comprises a shield 1 (see fig. 3, 4, and 5) connected to an ear plate 5 (see fig. 13, 14, and 15), a support 4 (see fig. 11 and 12), and a bracket 3 (see fig. 8, 9, and 10) disposed on a side frame and a carriage of the power head in a bilateral symmetry manner through a matched bolt group; an installation and maintenance window matched with the installation position of the hydraulic motor connected in series with the driving motor is formed in the protective cover, and an end cover 2 (see fig. 6 and 7) used for sealing the window is packaged at the window through a bolt assembly (when the hydraulic motor needs to be connected in series above the power head driving motor, the three end covers 2 installed through the bolt groups can be detached, and the normal installation of the hydraulic motor is ensured); the inner side surface of the shield is fixedly connected with a reinforcing rib and a rib plate.
The utility model not only reasonably and effectively utilizes the space and structure surrounded by the parts such as the side frame of the motor direct-drive power head, the sliding frame, the driving motor and the like, but also arranges the protective cover with light structure and convenient assembly and disassembly; simultaneously, the reasonable design can be used for disassembling the end cover, reserving the installation position of the hydraulic motor and having multiple functions.
