Detailed Description
The technical scheme of the utility model is further described below with reference to the accompanying drawings and examples.
As shown in fig. 1-3, an embodiment of the present utility model provides a multi-head drilling machine, including:
a supporting platform 1, wherein a hydraulic power unit 9 is fixed on the supporting platform 1;
the drilling assembly is arranged on the supporting platform 1 and comprises a rotary pin 2, a drilling machine arm 3 is rotatably connected to the rotary pin 2, and a drilling mechanism is arranged at the tail end of the drilling machine arm 3;
the multi-group driving assembly is respectively matched with the drilling assembly, the driving assembly comprises a first hinging seat 4, the first hinging seat 4 is fixed on the supporting platform 1, the first hinging seat 4 is hinged with the tail end of a telescopic oil cylinder 10, a second hinging seat 5 is fixedly connected to the drilling arm 3, and the top of an oil cylinder rod of the telescopic oil cylinder 10 is hinged to the second hinging seat 5.
When the drilling machine is used, when tunneling and drilling of a tunnel are needed, a proper working area is found, and then the telescopic oil cylinder 10 of the driving assembly stretches out and draws back, wherein the telescopic oil cylinder 10 conveys power through a hydraulic pump in the hydraulic power unit 9, so that the drilling machine arm 3 is driven to swing, and finally the drilling machine arm 3 can perform the drilling action through angle overturning through an overturning assembly on the drilling mechanism, wherein the driving assembly and the drilling assembly are multiple groups, so that multiple areas can be simultaneously processed at one time, the drilling efficiency of the drilling machine is effectively improved, and the drilling machine arm 3 is rotatably connected to a rotating pin 2 in order to enable the drilling machine arm 3 to be simple in structure and convenient to maintain when rotating.
Furthermore, two rotating pin 2 brackets are fixedly connected to the supporting platform 1, and the rotating pin 2 is detachably fixed in the rotating pin 2 brackets. Because be fixed with the rotatory round pin 2 support on supporting platform 1, rotatory round pin 2 is directly fixed in this rotatory round pin 2 support, through this kind of structure, make the top and the bottom homoenergetic of rotatory round pin 2 fix in rotatory support, thereby make it have sufficient support when bearing the load, can not take place deformation, in addition, because rotatory round pin 2 is detachable connection, later stage is more convenient when changing, concrete connected mode can be set up the screw thread section in rotatory round pin 2 bottom, through threaded connection on rotatory round pin 2 support, in order to avoid vibration to deviate from, rotatory round pin 2 top can also be fixed at the top of rotatory round pin 2 support through journal stirrup and screw.
Further, the arm 3 is rotatably connected to the rotary pin 2 via a rotary drum 7. Specifically, the rotary drum 7 is fixed at the tail end of the drilling machine arm 3, and is directly connected with the rotary pin 2 in a rotary way through the rotary drum 7, so that the contact area is larger, the stress of the rotary pin 2 is more uniform, and the rotary pin is not easy to deform, so that the service life of the rotary pin is prolonged.
Further, the drilling assembly and the driving assembly are two groups. Specifically, the drilling assembly and the driving assembly are two groups, so that the efficiency can be improved by multiple times, if the drilling assembly is too much, the hydraulic power unit 9 with larger driving force is needed, the cost is more expensive, meanwhile, the supporting platform 1 also needs to be amplified, occupies more volume, and is not easy to enter and exit for some small tunnels.
Further, the rotating pin 2 or the rotating cylinder 7 is provided with a lubricant injection hole 8. In order to make the drill arm 3 smoother when rotating, it is often necessary to fill lubricating oil between the rotation pin 2 and the rotation cylinder 7, and in order to make the lubricating oil injection more convenient, it is unnecessary to disassemble the drill arm when injecting, a lubricating oil injection hole 8 is formed in the rotation pin 2 or the rotation cylinder 7, wherein the injection hole is a through hole penetrating through the rotation pin 2 or the rotation cylinder 7.
