The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the features of the embodiments and examples of the present invention may be combined with each other without conflict.
The embodiments of the invention will be further explained with reference to the drawings, in which:
referring to fig. 1 and 2, there is shown a construction of a mining apparatus including: the body frame 33, the cutting part, the shovel part 11, the walking part 13, the first conveyor 10 and the control system. Wherein, the cutting part comprises at least two cutting arms (two are shown in the figure) and a cutting head arranged at the front end of the cutting arms, and the at least two cutting arms are connected to the upper side of the front part of the body frame 33 through at least two rotating mechanisms. The shovel portion 11 is provided on the lower front portion of the main body frame 33. The traveling units 13 are provided on both sides of the bottom of the main body frame 33. At least a portion of the first conveyor 10 is disposed in the body frame 33 and connected to the blade portion 11 for transporting the cut material collected in the blade portion 11. The control system is disposed on the body frame 33 for controlling the working states of the cutting unit, the shovel 11, the traveling unit 13, and the first conveyor 10.
Wherein the number of turning mechanisms and cutting arms may be the same, as shown in fig. 1, one turning mechanism is used for each of the two cutting arms. Alternatively, the number of slewing mechanisms may also be less than the number of cutting arms, e.g. when the number of cutting arms is more than two, two cutting arms may share one slewing mechanism.
In the above embodiment, the excavating and mining equipment is provided with at least two cutting arms, and the at least two cutting arms are connected with the body frame through the independent rotating mechanisms, so that not only can the positioning cutting range be enlarged, but also the safety and reliability of the equipment can be improved. In addition, the at least two cutting arms are respectively provided with the independent cutting head and the independent cutting motor, the cutting power of the cutting arms is at least twice of that of the single cutting arm, and the cutting power of the whole machine is large and the cutting efficiency is high. Therefore, the excavating and mining equipment integrates cutting, transportation, walking and intelligent operation, not only has a large positioning cutting range, but also has a section which can be formed at one time, and has high cutting efficiency, thereby being suitable for the requirements of comprehensive excavation and continuous mining of a mine with an ultra-large section.
In the above embodiment, the swing mechanism may alternatively include a swing table, a swing support, and a swing cylinder, the swing table being connected to the body frame 33 through the swing support. The front end hinge point of the rotary oil cylinder is connected with the rotary table, the rear end hinge point is connected with the body frame 33, and the rotary oil cylinder is used for pushing the rotary table to rotate.
Wherein, the gyration hydro-cylinder can include: the left rotary oil cylinder is arranged on the left side of the rotary table, and/or the right rotary oil cylinder is arranged on the right side of the rotary table. In specific implementation, the revolving platform can realize revolving operation by adopting a single oil cylinder, but in order to improve the stability and reliability of the revolving operation, a double-side oil cylinder driving mode is preferably adopted, namely, the revolving oil cylinders are arranged on the left side and the right side of the revolving platform.
On the basis of the above embodiment and various optional modes, the cutting part may further include a cutting arm lift cylinder, the rear end of the cutting arm is hinged to the turntable, one end of the cutting arm lift cylinder is connected to the turntable, and the other end is connected to the cutting arm. The cutting arm lifting oil cylinders are used for controlling and adjusting the movement of the cutting arm in the up-and-down direction, and in order to further improve the stability and reliability of the lifting operation, two cutting arm lifting oil cylinders are preferably configured on one cutting arm.
In the following, taking the excavating and mining equipment with the bilaterally symmetrical double cutting arms (located at the upper side of the front part of the body frame) as an example, and combining with the above-mentioned various preferred modes, the connection form and movement form will be described:
as shown in fig. 1 and 2, the left and right cutting heads are powered by independent cutting motors, and move up and down, left and right along with the left and right cutting arms to cut ore, and the star wheel 23 and the rake of the shovel plate part 11 move to receive the material, and the bulk material is conveyed to the rear side of the whole machine by the first conveyor 10.
The rear end of the left cutting arm 1 is connected with a left rotary table 30, the left rotary table 30 is connected above a body frame 33 through a left rotary support 32, the front end hinge points of the first right rotary oil cylinder 17 and the first left rotary oil cylinder 18 are connected with the left rotary table 30, the rear end hinge point is connected with the body frame 33, and the left rotary table 30 is pushed to rotate under the action of the first right rotary oil cylinder 17 and the first left rotary oil cylinder 18, so that the left and right direction swinging of the left cutting arm 1 is realized. And the left cutting arm 1 can swing up and down under the action of the two left cutting arm lifting oil cylinders 2.
Similarly, the rear end of the right cutting arm 3 is connected with the right turntable 34, the right turntable 34 is connected above the body frame 33 through a right slewing bearing, the second right slewing cylinder 20, the front end hinge point of the second left slewing cylinder 21 is connected with the right turntable 34, the rear end hinge point is connected with the body frame 33, the right slewing cylinder 20 and the second left slewing cylinder 21 are used for pushing the right turntable 34 to rotate, so that the left and right swinging of the right cutting arm 3 is realized, and the two right cutting arm lifting cylinders 4 can be used for realizing the swinging of the right cutting arm 3 in the up and down directions.
It should be noted that the left revolving platform 30 and the right revolving platform 34 are independent from each other and have no direct action relationship, the left revolving support and the right revolving support are also independent from each other and have no direct action relationship, and the two cutting arms move independently, i.e. the movement in the up, down, left and right directions is not related to each other, so that the whole movement range of the left cutting arm 1 and the right cutting arm 3 can be effectively enlarged. For example: as shown in fig. 2, the single movement range of the right cutting arm 3 can be from position a to position B, and the single movement range of the left cutting arm 1 can be from position C to position D, so that the movement range of the left and right cutting arms is larger in this embodiment compared to the movement range of a single cutting arm or a double cutting arm controlled by a single turntable. In order to prevent interference, the left cutting arm and the right cutting arm which can be arranged on the same horizontal plane can avoid reaching the central line position at the same time, but one cutting arm can reach the central line position when the other cutting arm is not at the central line position or under the condition of no collision alarm.
In addition, a cutting motor is respectively arranged on the left cutting arm 1 and the right cutting arm 3, so that the total cutting power is at least twice of the cutting power of the single cutting arm, and the cutting efficiency is greatly improved. Moreover, the front end of the left cutting arm 1 is provided with the left-handed cutting head 22, and the front end of the right cutting arm 3 is provided with the right-handed cutting head 16, so that when the two cutting arms work, the respective stress can be at least partially offset, and the stability of the whole machine is facilitated.
In order to reduce the number of times of left and right movement of the whole machine during work, the left cutting arm 1 and the right cutting arm 3 can independently pass through the center line but cannot simultaneously pass through the center line, otherwise, the two arms may collide with each other. For this purpose, some measures for collision avoidance are proposed here, as follows:
referring to fig. 3 and 4, which respectively show the arrangement of the turn table of the present embodiment from different perspectives,
in this embodiment, the excavating and mining equipment may further include at least two anti-collision blocks. The crash block may be attached to the turntable or integrally formed with the turntable. Wherein, the anti-collision blocks positioned between the adjacent rotary tables are oppositely arranged, and the two anti-collision blocks which are oppositely arranged can collide before the two corresponding cutting arms collide. For example, the left and right rotary tables are respectively provided with an anti-collision block, the anti-collision blocks can rotate along with the left and right rotary tables, when the left and right rotary tables respectively drive the left and right cutting arms arranged on the left and right rotary tables to move to a certain position towards the middle, the anti-collision blocks arranged on the inner sides of the left and right rotary tables collide with the left and right cutting arms in advance to prevent the left and right cutting arms from directly colliding.
In an optional implementation manner, the excavation and mining equipment may further include: alarm sensor 35 and sensor sensing board 39. The alarm sensor 35 is mounted below the crash block. The sensor sensing plate 39 is provided below the impact prevention block opposite to the impact prevention block on which the alarm sensor 35 is mounted. The warning sensor 35 is adapted to interact with the sensor sensing plate 39 and to generate and send a warning signal to the control system when the crash block is moved to a warning position. The control system is used for indicating alarm according to the warning signal.
On this basis, the excavating and mining equipment can also comprise: the emergency stop sensor 36, the emergency stop sensor 36 and the alarm sensor 35 are arranged below the same anti-collision block. The scram sensor 36 is configured to interact with the sensor sensing plate 39 and generate and send a scram signal to the control system when the crash block crosses the warning location. The control system is used for automatically cutting off the oil circuit of the rotary oil cylinder on the rotary table connected with the emergency stop sensor 36 and the sensor induction plate 39 according to the emergency stop signal. During specific implementation, the anti-collision block, the alarm sensor 35 and the emergency stop sensor 36 can be arranged on the inner side of the rotary table and can swing left and right along with the rotary table, so that the left cutting arm 1 and the right cutting arm 3 are protected.
In the following, taking the excavating and mining equipment with bilaterally symmetrical double cutting arms (located at the upper side of the front part of the body frame) as an example, the anticollision measures will be described with reference to fig. 3 and 4:
as shown in fig. 3 and 4, at least two crash blocks include: a left anti-collision block 38 and a right anti-collision block 37, wherein the left anti-collision block 38 is connected with the left rotary table 30, and a sensor induction plate 39 is arranged below the left anti-collision block 38. The right anti-collision block 37 is connected with the right rotary table 34 and is arranged opposite to the left anti-collision block 38; and an alarm sensor 35 and an emergency stop sensor 36 are arranged below the right anti-collision block 37.
Optionally, the excavation equipment of the above embodiment may further include an alarm anti-collision device for the left and right rotary cylinders of each rotary table, for example, the excavation equipment may further include: a first bottom alarm sensor 27, a second bottom alarm sensor 29, and a bottom sensor sensing pad 28.
Wherein, first bottom alarm sensor 27 sets up on body frame 33, is located revolving platform left side below, and first bottom alarm sensor 27 is used for detecting whether left revolving cylinder reaches extreme position. The second bottom alarm sensor 29 is arranged on the body frame 33 and located below the right side of the rotary table, and the second bottom alarm sensor 29 is used for detecting whether the right rotary cylinder reaches a limit position. The bottom sensor sensing plate 28 is mounted below the turntable and is movable with the turntable.
In the working process, the first bottom alarm sensor 27, the second bottom alarm sensor 29 and the bottom sensor induction plate 28 act, and limit position warning signals are generated and sent to the control system when the left and right rotary oil cylinders stretch to limit positions. And the control system indicates alarm according to the extreme position warning signal. The alarm device gives an alarm according to the indication of the control system and reminds an operator that the left rotary oil cylinder and/or the right rotary oil cylinder stretch to the limit position.
In addition, optionally, the excavating and mining equipment may further include: first bottom scram sensor 26 and second bottom scram sensor 31, first bottom scram sensor 26 set up on body frame 33, are located revolving platform left side below, and first bottom scram sensor 26 is used for detecting whether left revolving cylinder reaches extreme position. The second bottom scram sensor 31 is arranged on the body frame 33 and located below the right side of the rotary table, and the second bottom scram sensor 31 is used for detecting whether the right rotary cylinder reaches a limit position. The bottom sensor sensing plate 28 is mounted below the turntable and is movable with the turntable.
During operation, the first bottom dead stop sensor 26, the second bottom dead stop sensor 31 and the bottom sensor sensing plate 28 act, and generate and send dead stop signals to the control system when the left and right rotary cylinders exceed the limit positions. And the control system automatically cuts off the oil paths of the left and right rotary oil cylinders according to the emergency stop signal.
Further, as shown in fig. 3 and 4, the collision avoidance process of the above-mentioned collision avoidance measures can be referred to as follows:
when the left and right turntables respectively drive the left and right cutting arms to move to a certain position towards the middle, the alarm sensor 35 firstly acts with the sensor induction plate 39 to send out a voice alarm to remind the operator that the left and right cutting arms should be moved towards the opposite direction. If the operator does not stop the wrong operation for some reason, the emergency stop sensor 36 will act on the sensor sensing plate 39 to send a signal, and will automatically cut off the oil paths of the first right slewing cylinder 17, the first left slewing cylinder 18, the second right slewing cylinder 20 and the second left slewing cylinder 21.
If the alarm sensor 35 and the emergency stop sensor 36 fail, the right anti-collision block 37 and the left anti-collision block 38 collide with the left cutting arm 1 and the right cutting arm 3 in advance, so that the left cutting arm 1 and the right cutting arm 3 are protected.
First bottom alarm sensor 27, second bottom alarm sensor 29, first bottom scram sensor 26, second bottom scram sensor 31 are connected with body frame 33, are located right revolving platform 34 below, and bottom sensor tablet 28 is connected and can be followed the revolving platform and move together in right revolving platform 34 below, after scram sensor and sensor tablet produced the signal after taking effect, can automatic cutout second right side gyration hydro-cylinder 20, the oil circuit of second left gyration hydro-cylinder 21, prevent that the hydro-cylinder from stretching to extreme position. Similarly, the same crash structure as described above is disposed below the left turntable 30.
It should be noted that, in the above embodiment, the excavating and mining equipment is exemplified to have the double cutting arms symmetrically disposed left and right, and the two corresponding turrets and slewing bearings thereof are disposed along the left and right direction of the main body frame 33 and are located on the same horizontal plane, but in other embodiments, more than two (e.g., three, four, etc.) independent cutting arms and the corresponding number of turrets and slewing bearings thereof may be employed, and are not limited to a symmetrical manner, for example, at least two turrets and slewing bearings are disposed on the main body frame 33 in a staggered manner in the front-back direction, or at least two turrets and slewing bearings are disposed on the main body frame 33 in a staggered manner in the up-down direction. Correspondingly, the left and right cutting arms in the above embodiments can also be arranged in a staggered manner in the front and rear directions, or in a staggered manner in the up and down directions.
In addition, each cutting arm can adopt an independent rotating mechanism and a control mode, and of course, under the condition of operation requirement, a linkage control mode of combining control can also be adopted for each cutting arm.
In the implementation process, the control of each cutting arm of the above embodiments can be realized by the following control system:
the control system comprises a hydraulic system 9 and an electrical system 19, which are arranged on the body frame 33, respectively. Wherein the hydraulic system 9 is provided with: the hydraulic control device comprises a single-action hydraulic control handle for independently controlling the cutting arm and a linkage hydraulic control handle for jointly controlling the cutting arm; and a control mode switching device is arranged between the single-action hydraulic control handle and the linkage hydraulic control handle.
For example, taking the case that two cutting arms arranged in the left-right direction are arranged at the front end of the whole machine, the left cutting arm and the right cutting arm are respectively connected with respective rotary tables, and the control system is provided with a single-acting hydraulic control handle corresponding to the left cutting arm and the right cutting arm, so that the two cutting arms can independently move, namely, the motions in the upper direction, the lower direction, the left direction and the right direction are not related to each other.
When the left and right cutting arms need to be controlled in a linkage mode, the mode switching button arranged on the control mode switching device can be pressed to switch the single hydraulic control handle into the linkage hydraulic control handle, and then the linkage hydraulic control handle is operated, so that the left and right cutting arms can move up and down simultaneously, or outward simultaneously, or towards the central line simultaneously.
