Description
Technical field
The present invention relates to a kind of twin shaft angel measuring instrument used in plant equipment, be especially applied in the twin shaft angel measuring instrument on rock drilling equipment.
Background technology
Current plant equipment will be rotated in different both directions sometimes according to the situation of work, and during driver's operation, must can see the angle-data that both direction is rotated, especially rock drilling equipment, the measurement of angle that all directions are rotated mainly uses twin shaft angel measuring instrument, but current twin shaft angel measuring instrument mainly uses sensor to measure, although sensor is highly sensitive, volume is little, but its interchangeability is poor, signal temperature influence is larger, and need to be equipped with electronical display instrument, therefore cost is very high.
Summary of the invention
Technical matters to be solved by this invention is: provide a kind of measurement accuracy good, twin shaft angel measuring instrument with low cost.
The technical solution adopted in the present invention is: provide a kind of twin shaft angel measuring instrument, comprise the first angle disk, the second angle disk and link, the first described angle disk and the second angle disk are all connected on link, and the second angle disk is vertically located at the side of the first angle disk; The card of described first angle disk is circumferentially provided with the region of 4 marks, 0 ~ 90 ° of scale, is provided with the first pointer pointing to scale vertically downward in the middle part of card; The sidewall of described second angle disk is provided with the region of 4 marks, 0 ~ 90 ° of scale, and be provided with the second pointer connected vertically and balancing weight mutually in the middle part of card, the second described pointer is horizontally disposed with, and the syringe needle at the second pointer two ends points to the scale on sidewall.
The scale of described first angle disk and the second angle disk adopts laser inscription or copybook to mark.
Described second angle disk is provided with arc bar shaped adjustment hole.
Described first angle disk is connected by the bolt running through both with link, and bolt is socketed with lining, and the first described pointer is connected on lining.
Described second angle disk is connected by the bolt running through both with link, and bolt is socketed with lining, and the second described pointer and balancing weight are all connected on lining, and the second pointer is connected with balancing weight.
After twin shaft angel measuring instrument of the present invention adopts above structure, link is arranged in plant equipment, plant equipment can obtain the rotational angle in both direction by the first angle disk and the angle between the second angle disk and the pointer on it when rotating, sensitivity is higher, measurement accuracy is good, compared with the angel measuring instrument of sensor, structure is simple, with low cost.

Embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail.
As shown in FIG. 1 to 3, twin shaft angel measuring instrument of the present invention, comprise the first angle disk 1, second angle disk 2 and link 3, first angle disk 1 and the second angle disk 2 are all connected on link 3, second angle disk 2 is vertically located at the side of the first angle disk 1, namely the card of the second angle disk 2 is vertical with the card of the first angle disk 1, the card of the first angle disk 1 is circumferentially provided with the region of 4 marks, 0 ~ 90 ° of scale, the scale in 4 regions is distributed in the circumferential edges of disk, the first pointer 4 pointing to scale is vertically downward provided with in the middle part of card, the sidewall of the second angle disk 2 is provided with the region of 4 marks, 0 ~ 90 ° of scale, namely the second angle disk 2 has certain thickness, scale is located on sidewall, the second pointer 6 connected vertically and balancing weight 5 is mutually provided with in the middle part of card, balancing weight 5 and the second pointer 6 are riveted, second pointer 6 is horizontally disposed with, and the syringe needle at the second pointer 6 two ends points to the scale on sidewall.
The present invention in the specific implementation, the scale of the first angle disk 1 and the second angle disk 2 adopts laser inscription or copybook to mark, first angle disk 1 is connected by the bolt running through both with link 3, bolt is socketed with lining, lining and bolt-clearance is adopted to be connected, first 4, pointer is connected on lining, second angle disk 2 is connected by the bolt running through both with link 3, bolt is socketed with lining, adopt lining and bolt-clearance to be connected, the second pointer 6 and balancing weight 5 are all connected on lining.
The present invention in the specific implementation, second angle disk 2 is provided with arc bar shaped adjustment hole 7, namely on disk except having the bolt hole that is connected with link 3, also have arc bar shaped adjustment hole 7, this arc bar shaped adjustment hole 7 is for correcting the initial angle of the second angle disk 2.
First pointer 4 of the first angle disk 1 in use, after being fixed on equipment, corrects link 3 to instruction 90 scale or 0 scale by the present invention, and bolt on (vibrations equipment need tighten with torsion); Adjusting the second pointer 6 by the arc bar shaped adjustment hole on the second angle disk 2 equally corrects to 0 scale, and tighten two bolts, during equipment work, on the first angle disk 1, the scale of instruction is the angle that a direction swings, and on the second angle disk 2, the scale of instruction is the angle that another one direction swings.Because the scale of the second angle disk 2 marks on sidewall, thus driver can observe the angle of two angle disks very easily in one direction simultaneously.
Sensitivity of the present invention is higher, and measurement accuracy is good, and material adopts cheap Q345 metal material to make, and compared with the angel measuring instrument of sensor, structure is simple, with low cost.
