Description
Technical field
The present invention relates to rock drill the field of test technology, and in particular to a kind of rock drill test run for blast furnace open hole machine
Device.
Background technique
Iron notch drill, which is used to bore on blast furnace, gets molten iron mouth, has rock drill in the composition of impact drill formula iron notch drill, bores
Bar is sequentially connected between the bit shank and drilling rod of rock drill by connector sleeve.Rock drill uses in installation to iron notch drill, or
When used for a long time, it needs to test the performance of rock drill, could be used after test passes.
Currently, to the performance test of rock drill being carried out by rock drill testing device, rock drill running support is for digging
Rock machine loads test run and running-in ability test, examines rock drill boring capacity and service life.Rock drill running support is to pass through simulation
The course of work of blast furnace open hole machine tapping outlet tests the performance of rock drill, specific (with reference to shown in Fig. 1, Fig. 2):
Rock drill 5 is installed on rock drill trolley 4, rock drill trolley 1 is fixed on beam-and-rail 3, and beam-and-rail 3 is fixed on door by attachment base 6
The center of type running support frame 1, drilling rod 8 are threaded on rock drill 5, and are connected with drill bit 9 in the end thread of drilling rod 8.
When test, rock drill 5 is driven by the feed mechanism 2 for being fixed on 3 end of beam-and-rail and being electrically connected with rock drill 5, the drive of rock drill 5 is set
It sets drilling rod 8 and the impact of drill bit 9 is located at the clump 7 of 1 front end of rock drill running support, rock drilling is realized according to the drilling situation of clump
The performance test of machine.But current rock drill running support has the disadvantage in that
(1) when rock drill test run, drill bit, drilling rod and clump need to be consumed or related substitute, test run are at high cost；
(2) when rock drill test run, drilling rod and drill bit impact clump or related substitute can generate small chip or dust, dirty
It contaminates environment and influences the health of operating personnel；
(3) beam-and-rail is the center that gate formula vehicle frame frame is detachably secured to by attachment base, if bolt occurs in commissioning process
Or other fixing pieces are when relaxing, so that running support bad stability, drilling rod and drill bit are trained off and are fanned the air when test run, rock drill impact
If power is easily destroyed rock drill when fanning the air greatly.
Therefore, it is necessary to the rock drill testing devices to blast furnace open hole machine in the prior art to be improved.
Summary of the invention
It is big, at high cost it is an object of the invention to solve rock drill running support consumption in the prior art, and cutting or powder
Dustiness contaminates the problem of environment, provides a kind of rock drill testing device for blast furnace open hole machine, rock drill examination of the invention
The long service life of vehicle device, at low cost, without dust pollution pass in and out test run suitable for the rock drill to various structures, are applicable in model
It encloses wide.
Realize that the technical solution of goal of the invention is as follows: a kind of rock drill testing device for blast furnace open hole machine, rock drilling
Machine testing device is fixed on device pedestal, and one end of device pedestal is fixed with rock drill fixing seat, and rock drill is detachably fixed
On rock drill fixing seat top, rock drill testing device includes colliding block, collides the front end that block is threaded in rock drill.
It further include rest pad, rest pad is fixed on rest pad frame upper close to block, rest pad is collided, and rest pad bracket is solid
It is scheduled on the other end of device pedestal.
It collides block and rest pad is that ferrous material is made, collision block and rest pad made of ferrous material
Hardness is high, is unlikely to deform when colliding block and hitting simultaneously spinning rest pad, is able to extend the service life for colliding block and rest pad.
Rest pad and the center for colliding block are located on same level straight line, and when test run, rock drill makes for driving collision block
It collides block and hits simultaneously spinning rest pad.
It further, is sharp drill bit frequently with end when existing rock drill test run, drill bit contacts simultaneously with clump
A large amount of clast and dust can be generated when drilling, generate dust when hitting rest pad in order to avoid the collision block connecting with rock drill
And clast, the impact surface for colliding block is plane.When test run, collide striking between block and rest pad and when spinning, because colliding block
Impact surface is plane, is also plane with rest pad contact surface, and when test run can only generate a small amount of heat, will not generate dust and
Clast.
Further, accurately to strike to rest pad convenient for colliding block, the impact surface for colliding block is made to be less than rest pad
Cushion faces.
Further, it can be suitably used for the progress test run of this testing device to make different types of rock drill, improve test run
The scope of application of device；And due to different rock drills, its specifications parameter is different, will collide block and is installed to rock drill to be tested
When upper, the center for colliding block and rest pad may not need to rock drill or collide the position of block on same level straight line
And size is adjusted.Therefore, rock drill testing device is additionally provided with rock drill transition seat, and the upper end of rock drill transition seat is detachable
Fixed rock drill, the lower end of rock drill transition seat is detachably secured in rock drill fixing seat.When rock drill test run, according to rock drilling
The rock drill transition seat of the size selection proper height of machine, makes to install in the center and rest pad for colliding block to rock drill
The heart is located on same level straight line.
As a further refinement of the present invention, in order to avoid rock drill driving collision block shock rest pad, branch when test run
Supporting block is detached from rest pad bracket and rock drill is caused to fan the air, and destroys rock drill.It is additionally provided with hydraulic cylinder in rock drill testing device, it is hydraulic
One end of cylinder is fixed on rest pad bracket, and the other end of hydraulic cylinder is fixed in hydraulic cylinders bearing, and hydraulic cylinders bearing is fixed on
On device pedestal.The nose threads of hydraulic cylinder are connected with rest pad, and when test run, hydraulic cylinder is used to provide support force for rest pad,
Hydraulic cylinder is that the support force that rest pad provides can satisfy load force required when rock drill test run.
Compared with prior art, the invention has the advantage that:
1. replacing drill bit, drilling rod, clump or related substitute using the collision block and rest pad of ferrous metal material, make rock drilling
Block is collided in machine commissioning process and rest pad is unlikely to deform, and loss is low, and service life with higher greatly reduces rock drilling vehicle
Test run cost.
2. colliding the contact surface between block and rest pad is smooth flat, in test run will not because collide block and rest pad it
Between hit generate dust pollution.
3. the hydraulic cylinder of rock drill testing device provides stable supporting force for rest pad, rock drill is avoided to fan the air and broken
It is bad.
4. rock drilling vehicle of the invention is fixed on device pedestal by rock drill transition seat, according to the rock drilling of different model
Machine selects different rock drill transition seats, and rock drilling vehicle testing device of the invention is enabled to be suitable for the examination of a variety of rock drills
Vehicle.
