Abstract

The utility model relates to an improved pneumatic bit prospecting machine comprising a prospecting bit, and a power driver. The driving part of the improved prospecting bit is composed of a cylinder and a two-position four-way double air controlled slide valve, an upper and a lower spacing travel switches, a four-way valve, a cut-off valve, etc. The utility model changes the up-and-down motion of the piston into the hammering of the hammer head to the anvil head, which makes the prospecting bit explore downward. The utility model has the advantage of compact structure, which can be manipulated by one person, increase the efficiency rate by ten times, and can be used widely in building construction.

Description

Pneumatic bit prospecting machine

The utility model relates to a kind of pricker for building and visits machine, belongs to building operations facility technical field.

In construction building, for grasping ground soil property parameter, need to carry out the inspecting hole test with drill steel, an area is 12400M ²Engineering foundation need visit 6340 holes.These holes all are in the past that artificial pricker is visited, if two people take turns flow operation, pricker was visited a hole in per 15 minutes, need with can finishing 395 work days, and labour intensity are big, and it is slow that pricker is visited speed, and the hammer force instability can not correctly reflect the actual conditions of ground.

In order to overcome above-mentioned manually-operated shortcoming, various prickers are visited machineries and are arisen at the historic moment, but these machineries all are to be motive power with the motor, slow down through reduction box, cooperate bent axle or eccentric wheel, move up and down to drive tup and carry out that the hammering pricker visits.These designs, though overcome manually-operated shortcoming, owing to adopt motor and reducer, it is big still to fail to solve weight, is difficult for mobile, unhandy shortcoming.

The purpose of this utility model is that a kind of new pricker of development is visited machine, and it should have light and flexible, and hammer force is stable, easy to operate, as correctly to reflect ground soil property situation advantage.

The purpose of this utility model is that power source is realized by adopting aerodynamic force.The utility model is described in further detail below with reference to accompanying drawing.

Fig. 1 is the utility model pneumatic schematic diagram.

Fig. 2 is a section of structure.

Fig. 3 is former parts installation site figure.

Pneumatic pricker is visited machine, its structure comprises visits pricker and power drive two parts, scheme after the improvement, its drive part is by cylinder 6, two-position four-way double air controlled guiding valve 5, spacing up and down (pneumatic)

travel switch

2,7, cross valve 4 and stop valve 3 are formed, described cylinder 6 is fixed on the support 11, piston rod 19 is linked together with tup 16, tup 16 hammerings are on anvil head 17, visiting pricker is fixed on the anvil head, described cylinder is controlled by two-position four-way double air controlled guiding valve, its two gas control ends, one 33 connects limitation travel switch 2 by the road, and the other end 34 connects lower limit travel switch 7 by the road, limitation travel switch 2 up and down, 7 and two-position four-way double air controlled guiding valve respectively by the

road

28,27,29 connect four-way 4, and the latter 30 connects source of the gas 1 by the road.

During operation, open stop valve 3, Compressed Gas makes cylinder piston move up and down, and when the limit inferior position was arrived in piston motion, spacing lance 22 made 7 actions of lower limit travel switch, make 5 commutations of two-position four-way double air controlled guiding valve, cylinder piston moves upward, and when the limes superiors position was arrived in piston motion, spacing lance 22 made 2 actions of upper limit travel switch, make the commutation of two-position four-way double air controlled guiding valve again, thereby cylinder piston is ceaselessly moved up and down.The effect of cross valve 4 is that source of the gas gas is supplied with two-position four-way double air controlled guiding valve and limitation travel switch up and down along separate routes.Moving up and down of piston becomes the motion of tup 16, and hammering constantly forms a downward vibration force on the anvil head, and this vibration force makes to be visited pricker and insert ground and more and more darker.

In order to regulate the hammer force of tup, in pipeline 32, insert a control valve 8.Regulate it, can change its hammer force and number of times.

When piston rod drove the tup hammering, its bump strength was bigger, is vibrations and the damage that alleviates frame, can be designed to elastic shock attenuation and connect.This elastic shock-absorbing device is made up of 15,4 uniform tappets 14 of buffer disc and 4 springs 21, is threaded on the tappet, can screw on the tup in the corresponding hole, and spring is placed on the tappet, and it plays cushioning effect between tup and piston.Piston rod then is fixed on the buffer disc.

In order to show the number of times of hammering, on support 11, can install a counter 20, counter can utilize spacing lance 22 to trigger, and spacing lance is whenever stirred once, and counter promptly counts once.

Counter can adopt mechanical counter, also can adopt electronic counter.

Cylinder of the present utility model seals with

potting

25,26 up and down, establishes the effect of cushion rubber with enhanced leaktightness in the potting again, processes screw thread respectively on the potting up and down, connects with upper and

lower covers

23,24 with this, and support 11 is two metal sheets, and branch stands in the cylinder both sides.Top is fixed together with bolt and loam cake 23, and the bottom then is welded on the lower cover 24.Piston rod 19 passes lower cover 24 backs and connects with buffer disc 15, and also adds cushion rubber with the gap between packed-piston bar and the lower cover, in addition, for the purpose of safety in the operation, connects casing 12 on lower cover 24.The latter also for anvil head 17 provides the permanent position, uses thread connection between the two simultaneously, and the side installs jackscrew again additional.Installing hole is established in the lower end of anvil head, visits pricker 18 and inserts in this hole, and hold out against with jackscrew.

Control assembly of the present utility model, as stop valve 3, cross valve 4,

limitation travel switch

2,7 up and down, two-position four-way double air controlled guiding valve 5, and control valve 8 grades directly are fixed on the support 11.Corresponding pipeline also directly connects as 27,28,29,30,31,32,33,34 etc., makes complete machine very compact light and handy.

Cylinder bore size of the present utility model can be selected in the 30-50mm scope, piston stroke 100-300mm, and the casing external diameter should select 100-150mm, visits the pricker external diameter and is about 20-30mm.Press the pricker spy machine that the utility model is made, compact conformation, light and handy, complete machine weight has only 16 kilograms, and one can easy manipulation and displacement.Existing electronic pricker is visited machine then mostly more than 50Kg, needs two people to operate.This machine pricker spy speed is 10 times that artificial pricker is visited speed, is 1.5 times that electronic pricker is visited machine, can be widely used in the building operations operation and go.
