Abstract
What the utility model discloses a kind of jumbo takes over a business mechanism; comprise: forward beam, support, buffer spring, take over a business seat and take over a business; support is fixed on above forward beam front end; take over a business the front end that seat is fixed on support; take over a business to be arranged on the front end of seat; buffer spring is arranged between seat and support; take over a business seat and take over a business center and be provided with through hole; size and the bit of rock drilling machine of through hole match; this jumbo take over a business mechanism; structure is simple, accurate positioning, can the rod bit of available protecting hammer drill not be damaged.
Description
Technical field:
The utility model relates to rock drilling equipment technical field, and what be specifically related to a kind of jumbo takes over a business mechanism.
Background technology:
In recent years, market increases day by day for the demand of the especially various rig of engineering machinery, and hammer drill is a kind of power tool for rock drilling boring.At present, for the excavation in tunnel, most still employing traditional manually holds hammer drill bore operation, and make programming slow, long in time limit, cost is high, and potential safety hazard is given prominence to, human and material resources, financial resources that loss is a large amount of.Along with the development of science and technology, be developed jumbo, jumbo is a kind of rock drilling equipment that tunnels and underground engineering adopts drill bursting construction, taking over a business is positioner on jumbo, but taking over a business of current jumbo is arranged for biased relative to drilling rod, because the shape of surrounding rock of holing is unpredictable, easily causes drill bit comparatively to take over a business and first touches rock, also be not fixed on scar at forward beam like this and just start boring, the problem occurring damaging rod bit can be caused.
Utility model content:
What the purpose of this utility model was to provide a kind of jumbo takes over a business mechanism, and structure is simple, accurate positioning, can the rod bit of available protecting hammer drill not be damaged.
To achieve these goals, the utility model adopts following technical scheme: a kind of jumbo take over a business mechanism, comprise: forward beam, support, buffer spring, take over a business seat and take over a business, support is fixed on above forward beam front end, take over a business the front end that seat is fixed on support, take over a business to be arranged on the front end of seat, buffer spring is arranged between seat and support, take over a business seat and take over a business center and be provided with through hole, size and the bit of rock drilling machine of through hole match.
Above-mentioned buffer spring is four, is evenly distributed on through hole surrounding.
Above-mentionedly take over a business to take over a business for round rubber.
Relative to prior art, the utility model has the following advantages:
1, in forward beam position fixing process; due to the center that drill bit is taken over a business at rubber; so the rock shape around whether apertures position how; good locating effect can be played; can not occur to run and bore phenomenon; this take over a business mechanism, make jumbo accurate positioning, the rod bit of available protecting hammer drill is not damaged.
2, in boring procedure, advance vibration of beam to be buffered spring absorb, simultaneous buffering spring can also compensate forward beam makes propelling pressure occur minor variations due to vibration, make can not have an impact to the pressure of scar, such forward beam also would not produce displacement and affect bore operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1, support; 2, seat is taken over a business; 3, take over a business; 4, buffer spring; 5, forward beam; 6, through hole.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the utility model is described in more detail.
As shown in Figure 1, a kind of jumbo take over a business mechanism, comprise: forward beam 5, support 1, buffer spring 4, take over a business seat 2 and take over a business 3, support 1 is fixed on above forward beam 5 front end, take over a business the front end that seat 2 is fixed on support 1, take over a business the front end that 3 are arranged on seat 2, buffer spring 4 is arranged between seat 2 and support 1, take over a business seat 2 and take over a business 3 centers and be provided with through hole 6, size and the bit of rock drilling machine of through hole 6 match.
Above-mentioned buffer spring 4 is four, is evenly distributed on through hole 6 surrounding.
Above-mentionedly take over a business 3 to take over a business for round rubber.
Forward beam 5 is pushed to after scar positions, hammer drill just starts to hole, when forward beam 5 pushes scar to, take over a business 3 and first touch scar, under the promotion of forward beam 5, support 1 compresses buffer spring 4, buffer spring 4 promotes seat 2, make 3 by inflexibly be pressed on scar, after taking over a business 3 location, hammer drill starts to start, drill bit by take over a business 3 and the through hole 6 of taking over a business in the middle of seat 2 stretch out 3 beginning bore operations, according to the position of taking over a business 3, rock drilling bore operation is carried out in the middle of taking over a business 3, rock shape around such whether apertures position how, the effect of location and protection drill bit preferably can be played, this take over a business mechanism's not only accurate positioning, can also the rod bit of available protecting hammer drill not be damaged.
This mechanism is provided with four buffer springs 4, be evenly distributed on through hole 6 surrounding, the pressure of taking over a business 3 pairs of scars is that forward beam 5 is passed over by four buffer springs 4, so, in boring procedure the vibration of forward beam 5 absorb by four buffer springs 4, make the pressure of 3 pairs of scars to have an impact, simultaneous buffering spring 4 can also compensate forward beam 5 makes propelling pressure occur minor variations due to vibration, and such forward beam 5 also would not produce displacement and affect bore operation.
Taking over a business 3 selects round rubber to take over a business, and frictional force is large, not easily occurs sliding in position fixing process, causes locating inaccurate situation.
Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model; can not assert that detailed description of the invention of the present utility model is only limitted to this; for the utility model person of an ordinary skill in the technical field; without departing from the concept of the premise utility; some simple deduction or replace can also be made, all should be considered as belonging to the utility model by submitted to claims determination scope of patent protection.
