Abstract
The utility model discloses a special drilling machine of railway bridge steel bracket comprises motor, support, locating pin, guide rail, handle, gear bush and the machines handle of taking the drill bit. Guide rail fixed mounting is in support upper portion, motor fixed mounting in rack bottom, handle fixed mounting holds in gear bush's off -axial, gear bush and machines handle fixed mounting are in the upper right portion of support, the rack passes through the effect of rack and pinion mechanism with gear bush. The utility model discloses need not to set up auxiliary assembly such as scaffold and safety net can be directly big on bridge to the steel bracket operation of holing. The special small -size worker that uses when driling the operation to the railway bridge pavement steel bracket construction equipment that is engaged in need not to set up complementary equipment such as scaffold and safety net in the underbridge during drilling, only need lift on bridge a small amount of side walk slab and can directly drill to the bridge steel support at the bridge floor, has that the operation security is good, the operating efficiency is high, lasts characteristics such as the strong and manpower and materials cost of work ability is few.
Description
Technical field
The utility model relates to a kind of drilling machine, particularly relates to a kind of railway bridge steel bracket Special drill machine.
Background technology
According to the regulation of Ministry of Railways's " notice about strengthening the preloading management of Railway Concrete Bridge steel bracket pavement " (No. [2012] 292, fortune work bridge tunnel letter) literary composition, railway bridge steel bracket is reinforced, to guarantee the personal safety of railroader after should carrying out drilling construction by " both wired concrete-bridge steel bracket pavement reinforced figure " (figure number: specially bridge (2012) 9028).The conventional boring method of railway bridge steel bracket adopts large area to remove side walk slab, the complementary equipment such as scaffold and safety net is set up under bridge, operating personnel fastens one's safety belt to stand on scaffold and holes to steel bracket with power drill, this method length consuming time, cost are high, the more operating personnel of need, and work high above the ground causes safety coefficient lower, and make simple construction complexity.
Summary of the invention
The purpose of this utility model is: improving operating efficiency, reduce operating cost, guarantee job safety, providing a kind of Bridge Steel support Special drill facility without the need to setting up scaffold, with meet operating personnel directly on bridge to the requirement that steel bracket is holed.
The purpose of this utility model is realized by following scheme: the motor of band drill bit, form for carrying the support of fixing angle steel, alignment pin, guide rail, handle, gear bush and facility handle, guide rail is fixedly installed in frame upper, and motor is fixedly installed in bottom tooth bar; Handle is fixedly installed in the axle outer end of gear bush; Gear bush and facility handle are fixedly installed in the upper right quarter of support; Rack and pinion axle sleeve is by pinion and rack effect.
Support adjustable length described in the utility model, and formed by two frameworks be mutually socketed and located by spring positioning pin.
The electric drilling machine of the slow-speed of revolution, high pulling torque selected by motor described in the utility model.
Support adjustable length scope described in the utility model is 980mm-1480mm.
The utility model directly can carry out bore operation to steel bracket without the need to setting up the auxiliary equipment such as scaffold and safety net on bridge.The special small work business construction equipment of use when bore operation carries out to railway bridge pavement steel bracket, without the need to setting up the complementary equipment such as scaffold and safety net under bridge during boring, only need raise a small amount of side walk slab on bridge can directly hole to bridge steel support at bridge floor, have that operational security is good, operating efficiency is high, continuous operation ability by force and manpower and materials cost the feature such as to lack.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model top view.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
The implementation case is by the motor 1 with drill bit 2, form for carrying the support 3 of fixing angle steel 10, alignment pin 4, guide rail 5, handle 7, gear bush 8 and facility handle 9.The adjustable length of support 3 is undertaken regulating by the fixed frame 3-1 be mutually socketed and adjustable frame 3-2 and is located by spring positioning pin 4; Guide rail 5 is fixedly installed in fixed frame 3-1 top; Motor 1 is fixedly installed in bottom tooth bar 6; Handle 7 is fixedly installed in the axle outer end of gear bush 8; Gear bush 8 and facility handle 9 are fixedly installed in the upper right quarter of support 3; Tooth bar 6 and gear bush 8 are by pinion and rack effect.Operating personnel is by the pinion rotation in crank handle 7 driven gear axle sleeve 8, thus band carry-over bar 6 and motor 1 horizontal movement, reach the object of boring.
For the spacing of the existing railway bridge steel bracket of the overwhelming majority between (980-1480) mm, therefore the minimal adjustment length of this pull bar is 980mm, is 1480mm to the maximum; Need spring positioning pin to locate when pull bar is adjusted to certain position (1380mm, 1480mm), ensure when bore operation firm stable.According to the actual conditions of boring, the electric drilling machine of the slow-speed of revolution, high pulling torque should be selected.
