Description
Technical field
The utility model relates to the engineering construction instrument, is a kind of special line for passenger trains bridge-collision-avoidance wall drill drilling machine support specifically.
Background technology
According to the Ministry of Railways " railway Eleventh Five-Year Plan ", the key task of China railways development at present concentrates on to be accelerated the flourishing railway network, carry forward vigorously the technical equipment modernization and guarantees six broad aspect such as safety of railway traffic.Eleventh Five-Year Plan railway construction scale is big, the height of standard, is to have no precedent on the Chinese Railway development history.In railroad bridge, constructing tunnel process, can the duration of insurance of guaranteeing the quality finish, and the raising labor productivity plays crucial effects to the success or failure of engineering.
Passenger dedicated railway Bridge is that both sides are followed successively by electric power, communication, signal cable groove from outside to inside on the box girder bridge bridge floor.Crashproof wall is a reinforced concrete structure, and thickness is 20 centimeters.Requirement according to the Line for Passenger Transportation construction technology, railway signals equipment is installed in the outside of crashproof wall by circuit without exception on the box bridge, equipment is installed the mode that adopts boring fixed angles base steel plinth on the crashproof wall, this mode has attractive in appearance, firm characteristics, and the problem of therefore bringing is exactly a large amount of bore operation.Crashproof wall is 20 centimeters thick reinforced concrete structures, and reinforcing bar is very close, and the difficulty of boring is well imagined.How innovating on instrument and improve, not only guarantee drilling quality but also the purpose of boosting productivity to reach, is a problem that must solve.
The method of hand held drilling is inadvisable, labour intensity height not only because the vibrations of rig make people's arm ache very soon, and since during rig work hand-held stability not enough, can't guarantee drilling accuracy, not only can't guaranteed efficiency but also can't ensure the quality of products.
Our producer that several families produce rig specially that instituted a survey, finding does not still have a product at the crashproof wall drill of railroad bridge hole at present on the market.Though have some manufacturer production to have the rig of support, concerning the construction of the special railway of visitor and inapplicable.
Summary of the invention
The purpose of this utility model provide a kind of can be efficiently, the stable rig support in special line for passenger trains bridge-collision-avoidance wall drill hole of finishing.
Described special line for passenger trains bridge-collision-avoidance wall drill drilling machine support is characterized in that: it is made of the cross support arm of being fixed in the perpendicular pole on the horizontal base and be fixed on the perpendicular rod bush, and described perpendicular pole sleeve pipe is placed in outside the perpendicular pole and with lifting screw and fixes; Described cross support arm going up fixedly is equipped with the rig clip, and the end of laterally adjusting screw rod is fixed with the rig seat, and the rig seat is arranged in the rig clip.
Lifting nut fixedly is housed respectively on the top of perpendicular pole and cross support arm and laterally adjusts nut, described lifting nut is connected with the horizontal screw flight of adjusting with lifting screw respectively with the horizontal nut of adjusting.
The Height Adjustment handle is equipped with on the top of described lifting screw, and the head end of laterally adjusting screw rod is equipped with horizontal adjustment handle.
Described perpendicular pole of being fixed on the base can have single or many, and the quantity of cross support arm is corresponding with perpendicular pole.
Through experiment repeatedly, the utlity model has following characteristics:
1. light.Weight support frame has only about 30 kilograms, and containing rig also only has 35 kilograms, is easy to loading and unloading and transportation;
2. stability is high when holing.Because base is stuck in the cable channel, so relatively more firm; Thereby guaranteed the accuracy of bore position;
3. drillhole height is easy to regulate.Regulating center bolt is the liftable rig;
4. used this support, rig does not directly contact with constructor's health, thereby has improved the safety of bore operation;
5. constructor's labour intensity has been reduced to minimum;
6. saving fund reduces labor cost, has improved operating efficiency, has significantly shortened the duration.
Performance analysis:
Carry out benefit calculation at hand-held boring with using this support dual mode of holing below.
Signalling arrangement mounting points every kilometer one place approximately on the box girder for passenger special line bridge, for example: every place needs drilling hole amount be: 8 in φ 50mm hole, 24 in φ 25mm hole.According to site test results, adopt hand-held every φ 50mm hole of holing to need 50 minutes approximately, φ 25mm hole needs 30 minutes approximately, and every place needs 1120 minutes (2.3 work day) altogether; The boring of employing support, every φ 50mm hole needs 30 minutes approximately, and φ 25mm hole needs 15 minutes approximately, and every place needs 600 minutes (1.25 work day) altogether.Specifically see the following form:
According to data computation in the form, human cost is amounted in the boring of every place: 736 yuan of hand-helds, 225 yuan of stent-types.Adopt after the support, human cost has directly been reduced by 70%, whole numeral is very considerable.
With the special engineering of Zheng Xi visitor is example, and about 180 places of shared signal equipment mounting points adopt after this support on the bridge, get final product more than 10 ten thousand yuan of direct saving funds.Moreover, it has also saved the time of half nearly for us, for carrying out follow-up work smoothly, guaranteeing that opening the duration provides temporal guarantee.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1-Height Adjustment handle, the 2-lifting screw, the 3-lifting nut, the perpendicular rod bush of 4-, 5-erects pole, 6-base, 7-are laterally adjusted handle, and 8-laterally adjusts screw rod, and 9-laterally adjusts nut, 10-cross support arm, 11-rig clip, 12-rig, 13-rig handle, 14-hollow boring bit.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified: special line for passenger trains bridge-collision-avoidance wall drill drilling machine support as shown in fig. 1, it is characterized in that: it is by the perpendicular pole 5 of being fixed on the horizontal base 6, erect cross support arm 10 formations of propping up on the rod bush 4 with being fixed in, a described perpendicular rod bush 4 is placed in to erect outside the pole 5 and with lifting screw 2 and fixes; On the described cross support arm 10 rig clip 11 is housed fixedly, the end of laterally adjusting screw rod 8 is fixed with rig seat 15, and in use, rig 12 just is positioned in rig seat 15 and the rig clip 11, and rig 12 therein can be movable.
It is as follows to use this support to carry out the process in crashproof wall drill hole:
On crashproof wall, mark the position of boring, determine the size of boring, select the drill bit of respective model.Because the purposes difference of boring, so the size of boring is also different, the bolt hole is φ 25mm, and through wires hole is φ 50mm.In hollow boring bit 14 positions at the first-class required drill bit of rig 12 front ends.
Support is placed in the cable channel, and rotation Height Adjustment handle 1 is with the drill bit bore position.Should guarantee that the rig support has a smooth working platform, drill bit is perpendicular to the boring plane.
Open generator, closed rig switch.
At last rig is withdrawed from residual concrete in the cleaning hollow boring bit.
