Description
Technical field
The present invention relates to a kind of traction mechanism more particularly to a kind of thruster of jumbo front haulage mechanisms.
Background technique
Front end wirerope is by front end articulated joint, wirerope body, rear hinged in existing thruster of jumbo front haulage mechanism
Head composition, preceding articulated joint and the preceding fixed axis connection in rock drill mounting base；Articulated joint is hinged by pin shaft and tension device afterwards,
Wherein location hole of the pin shaft on tension device, and limited with split pin；Wirerope body is passed through from tension device, tenses dress
It is equipped with multiple rows of location hole；Big adjusting and minor adjustment are divided into the adjusting of front haulage mechanism elasticity, are adjusted to rear articulated joint greatly
Installation corresponding with the location hole of different location；Minor adjustment is to guarantee that rear end articulated joint and tension device relative position are constant
In the case of, the position of integrally-regulated tension device.
In progradation, front end wirerope belongs to active wirerope, inside always with the presence of pulling force, always in
Tight shape.In retraction process, rear end wirerope belongs to active wirerope, inside always with the presence of pulling force, always in tensioning
Shape, and front end wirerope belongs to passive wirerope in the process, inside substantially without pulling force, relaxed state is in, in this shape
Under state, wirerope body is from the phenomenon in the gap deviate from the groove of pulley and be stuck between support plate and pulley frequent occurrence,
Wirerope body is easily caused to be squeezed off.It is tensioned in the state of if wirerope is in relaxation in front end, in progradation
In, rate of tension is excessive again for front end wirerope, is easy to break.
Simultaneously as tension device is located inside propeller, and in the lower section of propelling cylinder, space is extremely narrow, these
Great difficulty all is brought to pulling pin during the steel rope replacing of front end, device to hole etc., leads to the replacement effect for replacing front end wirerope
Rate is very low.

Specific embodiment
To keep the purposes, technical schemes and advantages of the invention implemented clearer, below in conjunction in the embodiment of the present invention
Attached drawing, technical solution in the embodiment of the present invention is further described in more detail.In the accompanying drawings, identical from beginning to end or class
As label indicate same or similar element or element with the same or similar functions.Described embodiment is the present invention
A part of the embodiment, instead of all the embodiments.The embodiments described below with reference to the accompanying drawings are exemplary, it is intended to use
It is of the invention in explaining, and be not considered as limiting the invention.Based on the embodiments of the present invention, ordinary skill people
Member's every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.Under
Face is described in detail the embodiment of the present invention in conjunction with attached drawing.
As shown in Figures 1 to 5, the movement of rock drill 4 is by propelling cylinder 3 and front haulage machine on thruster of jumbo
Structure, the cooperation of rear haulage mechanism are completed；Front haulage mechanism is by front end wirerope II 1, front end pulley assembly 8, tension device II 10
Composition, front end pulley assembly 8 include support plate 81 and pulley 82；Rear haulage mechanism is by rear end wirerope 2, reel 6, oil tube bracket
9 compositions.Rock drill 4 is fixed in rock drill mounting base 5；The piston rod 31 and propeller of propelling cylinder 3 are relatively fixed, cylinder barrel 32
It can move forward and backward, and cylinder barrel 32 and reel mounting base 7 are relatively fixed, while cylinder barrel 32 and front end pulley assembly 8 are relatively fixed；Volume
Disk 6 and reel mounting base 7 are relatively fixed, and can rotate in reel mounting base 7；The rear end of front end wirerope II 1 and propulsion
Device tail portion is relatively fixed, and the front end of front end wirerope II 1 and rock drill mounting base 5 are relatively fixed, at the same front end wirerope II 1 around
Cross front end pulley assembly 8；2 front end of rear end wirerope and oil tube bracket 9 are fixed, and the rear end of rear end wirerope 2 and rock drill are installed
Seat 5 is fixed, while rear end wirerope 2 bypasses reel 6.
Progradation are as follows: propelling cylinder 3 extends, and front end pulley assembly 8 and reel mounting base 7 is driven to move forward；Due to front end
The rear end of wirerope II 1 is fixed, during front end pulley assembly 8 moves forward, before front end wirerope II 1 pulls rock drill mounting base 5
It moves, rock drill 4 moves forward therewith；Reel 6 moves forward with reel mounting base 7, and rear end wirerope 2 is mobile with rock drill mounting base 5.
Retraction process are as follows: propelling cylinder 3 bounces back, and reel mounting base 7 is driven to move back, and then reel 6 is driven to move back；Reel 6
Rear end wirerope 2 is acted on, since the front end of rear end wirerope 2 and oil tube bracket 9 are fixed, under the drive of reel 6, rear end steel
Cord 2 drives rock drill mounting base 5 to move back, and then rock drill 4 is driven to move back.
As shown in Figure 7 to 9, front end wirerope II 1 is hinged by front end in existing thruster of jumbo front haulage mechanism
First 101, wirerope body 102, rear articulated joint 103 form, and preceding articulated joint 101 connects with the preceding fixing axle 51 in rock drill mounting base 5
It connects；Articulated joint 103 is hinged by pin shaft 11 and tension device II 10 afterwards, wherein positioning of the pin shaft 11 on tension device II 10
Hole 1002, and limited with split pin 12；Wirerope body 102 is passed through from tension device 10, and tension device II 10 has multiple rows of positioning
Hole 1002；To the adjusting of front haulage mechanism elasticity be divided into it is big adjust and minor adjustment, be adjusted to greatly by rear articulated joint 103 from it is different
The corresponding installation of location hole 1002 of position；Minor adjustment is to guarantee rear end articulated joint 103 and 10 relative position of tension device not
In the case where change, the position of integrally-regulated tension device II 10.
In progradation, front end wirerope II 1 belongs to active wirerope, inside always with the presence of pulling force, locate always
In tensioning shape.In retraction process, rear end wirerope 2 belongs to active wirerope, inside always with the presence of pulling force, be in always
Be tensioned shape, and front end wirerope II 1 belongs to passive wirerope in the process, inside substantially without pulling force, be in relaxed state,
In this case, frequent occurrence wirerope body 102 from deviating from the groove of pulley 82 and be stuck between support plate 81 and pulley 82
Gap in phenomenon, easily cause wirerope body 2 to be squeezed off.If wirerope 1 is in it in the state of relaxation in front end
Tensioning, then in progradation, rate of tension is excessive again for front end wirerope 1, is easy to break.
Simultaneously as tension device II 10 is located inside propeller, and in the lower section of propelling cylinder 3, space is extremely narrow,
These all bring great difficulty to pulling pin in II 1 replacement process of front end wirerope, device to hole etc., cause to replace front end wirerope 1
Replacement efficiency it is very low.
