Description

Technical Field

[0001] The invention belongs to the technical field of mining support equipment, and in particular relates to a self-falling anchor feeding device. Background Art

[0002] During the construction of engineering tunnels and coal mine tunnels, after the tunnel is excavated, the rocks above and on the sides (or coal seam gangue) are in danger of collapse due to gravity. In order to maintain the stability of the main structure of the tunnel and avoid secondary hazards caused by collapse, it is necessary to support the top and side of the tunnel. The support operation is to fix and connect the anchor net by driving anchor rods into the rock layer (or coal seam) to achieve support and reinforcement of the entire tunnel surface. This requires driving multiple anchor rods into the tunnel section at short depths, so the amount of anchor rods used is very large.

[0003] In the prior art, there are three main anchor rod supply methods for automated support processes: parallel transmission rod supply, turntable rod supply and multi-stage robotic arm transfer rod supply. Among them, the parallel transmission rod supply is to use a transmission mechanism such as a chain to transmit the parallel arranged anchor rods one by one to the fixed position of the drilling mechanism. The number of anchor rods that can be arranged is limited, the relative position of the rod supply device and the drilling mechanism is fixed, and the space utilization rate is low. The turntable rod supply is to put the anchor rod into the turntable in advance, and use the rotation of the turntable to cooperate with the gripping of the robot to realize the rod supply. It is often necessary to arrange the rod supply mechanism and the drilling mechanism in parallel, and the relative position is fixed, resulting in a large volume of the entire mechanism and a limited number of stored anchor rods. The multi-stage robotic arm transfer rod supply method is suitable for relatively thick drill rods, such as directional drilling. The control program of its multi-stage robotic arm is relatively complicated, the flexibility is insufficient, and the overall cost is high. Summary of the invention

Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meanings of "multiple" and "several" are two or more, unless otherwise clearly and specifically defined.

[0020] Please also read Figures 1 to 8Now, a self-falling anchor feeding device provided by the present invention is described. The self-falling anchor feeding device comprises a rod bin 1, a material distribution mechanism 2 and a rod receiving platform 3. The rod bin 1 is used to store a plurality of anchors 10. The bottom of the rod bin 1 has a material drop channel 11. The plurality of anchors 10 in the material drop channel 11 are stacked up and down in sequence. The material distribution mechanism 2 comprises a first plug plate 21 and a second plug plate 22. The first plug plate 21 is slidably connected to one side of the rod bin 1. The second plug plate 22 is slidably connected to the other side of the rod bin 1 and is located above the first plug plate 21. The first plug plate 21 and the second plug plate 22 are alternately inserted into the material drop channel 11, and are used to support and separate two upper and lower adjacent anchors 10 in sequence, so that the anchors 10 fall one by one. The rod receiving platform 3 is located below the rod bin 1. The rod receiving platform 3 is used to receive the anchors 10 falling from the material drop channel 11.

[0021] The present embodiment provides a self-dropping anchor feeding device. Compared with the prior art, by setting a material drop channel 11 at the bottom of the rod bin 1, it is convenient for the anchors 10 stored in the rod bin 1 to enter the material drop channel 11 in an orderly manner. At the same time, with the alternating insertion of the first plug plate 21 and the second plug plate 22, the anchors 10 in the material drop channel 11 can be effectively separated and automatically drop under the action of gravity. The rod receiving platform 3 located below the rod bin 1 can stably receive the anchors 10 dropped from the material drop channel 11, which is convenient for the subsequent transportation of the anchors 10. In the above structure, the rod bin 1, the material distribution mechanism 2 and the rod receiving platform 3 cooperate with each other to form a relatively automated anchor feeding device, which reduces the manual intervention link, reduces the difficulty and labor intensity of manual operation, and the device has a relatively low demand for the electrical system, strong system robustness and good economy. At the same time, the overall structure of the device is simple and compact, and the space utilization rate is high. By reasonably designing the structure of the rod bin 1, large-capacity storage of anchors 10 can be achieved, which helps to improve work efficiency.

[0022] In this embodiment, the structure of the rod bin 1 can be flexibly selected according to the on-site usage conditions. It is sufficient to set a blanking channel 11 at the bottom of the rod bin 1 for stacking the anchor rods 10 in a single row. The first plug plate 21 and the second plug plate 22 are both slidably connected to the two side walls of the blanking channel 11, so that they can be inserted into the blanking channel 11 through horizontal sliding to separate the anchor rods 10 one by one.

[0023] Specifically, Figure 3Several structures of the rod bin 1 are listed in the specification. The single-width vertical rod bin is vertically arranged as a whole with a narrow width. The anchor rods 10 are arranged vertically in the rod bin 1, which is suitable for situations where space is limited and the demand for anchor rods is not large; the single-width inclined rod bin has a certain inclination angle with the vertical direction. The anchor rods 10 can slide down along the inclined direction under the action of gravity, which is convenient for automatic feeding; in the above two rod bin structures, the entire rod bin can be used as a blanking channel 11, and the first plug plate 21 and the second plug plate 22 are both horizontally slidably connected to the two side walls of the rod bin 1. The widened vertical rod bin has an increased accommodating width based on the single-width vertical rod bin, which can accommodate more anchor rods and reduce the frequency of adding anchor rods; the single-sided funnel-type rod bin is shaped like a funnel with a single-sided opening. The anchor rods 10 are naturally accumulated in the rod bin 1 and are orderly delivered from one side outlet; the double-sided funnel-type rod bin is a funnel structure with double-sided openings, which can supply anchor rods from both sides at the same time, thereby improving the supply efficiency and increasing the storage quantity of anchor rods; the irregular rod bin is designed according to special usage scenarios and needs. Its shape and structure are flexible and can adapt to the anchor supply conditions in complex environments.

[0024] The connecting rod platform 3 corresponds to the outlet end of the material drop channel 11 up and down. In practical applications, the connecting rod platform 3 is as close to the outlet end of the material drop channel 11 as possible to stably receive the falling anchor rod 10. Specifically, a row of rollers can be arranged on the receiving surface of the connecting rod platform 3, and the rollers are provided with receiving grooves arranged circumferentially. The multiple receiving grooves can reliably receive the anchor rod 10, and at the same time, in the subsequent transfer process of the anchor rod 10, it helps to reduce the hard wear of the anchor rod 10. Furthermore, side baffles extending outward and upward can be arranged on both sides of the connecting rod platform 3, respectively, to guide the anchor rod 10 to fall into the receiving groove during the falling process of the anchor rod 10, and at the same time prevent the anchor rod 10 from bouncing off the connecting rod platform 3 due to gravity after falling, thereby ensuring the stability of the operation process of the device.

[0025] In the initial state, see Figure 1 , the anchor rods 10 are arranged in the blanking channel 11 from top to bottom, the first plug plate 21 extends into the blanking channel 11 and supports the bottom of the lowest anchor rod, and the second plug plate 22 is located on the outside of the blanking channel 11; when the rod supply starts, the second plug plate 22 moves horizontally into the blanking channel 11, inserts between the lowest anchor rod and the second lowest anchor rod and supports the bottom of the second lowest anchor rod, and at the same time, the first plug plate 21 moves outward from the blanking channel 11, so that the lowest anchor rod loses its supporting function and falls onto the rod receiving platform 3; then, the first plug plate 21 and the second plug plate 22 move right synchronously, the second plug plate 22 moves out, the first plug plate 21 moves in, and the anchor rod in the blanking channel 11 falls onto the first plug plate 21 again. This alternating support and release method can accurately control only one anchor rod to fall each time, ensure the accuracy and continuity of the anchor rod supply process, and meet the needs of using anchor rods one by one and in an orderly manner during construction.

[0026] As a specific implementation of the embodiment of the present invention, please refer to Figure 6 The self-falling anchor rod 10 feeding device also includes a steering lifting mechanism 4, which is located at the lower side of the rod bin 1. The steering lifting mechanism 4 is used to clamp the end of the anchor rod 10 and drive the end of the anchor rod 10 to move upward so that the anchor rod 10 is inclined or vertical.

[0027] In this embodiment, when the anchor rod 10 falls horizontally onto the connecting rod platform 3, the steering lifting mechanism 4 is used to lift one end of the anchor rod 10, so that the anchor rod 10 can be supplied in an inclined or vertical state, thereby facilitating the subsequent grasping of the manipulator or docking with the drilling mechanism. For example, in some construction sites with limited space or special requirements for the installation angle of the anchor rod, the inclined supply can better adapt to the site conditions and facilitate the smooth installation of the anchor rod; the vertical supply can be suitable for the scene where the anchor rod is installed vertically.

[0028] The method of using the steering and lifting mechanism 4 to turn and lift the fallen anchor rod greatly improves the flexibility and adaptability of the anchor rod supply process. Compared with the traditional fixed posture supply method, it reduces the time and workload of secondary adjustment of the anchor rod posture at the installation site, optimizes the entire construction process, saves construction time, and greatly improves construction efficiency.

[0029] Specifically, the steering lifting mechanism 4 can adopt a structure of a jacking cylinder plus a claw: the jacking cylinder is vertically arranged at one end of the connecting rod platform 3, and one end of the anchor rod 10 is clamped by the claw, and then the claw is lifted upward by the jacking cylinder, thereby driving one end of the anchor rod 10 to move upward, thereby realizing the steering lifting of the anchor rod 10. The steering lifting mechanism 4 can also adopt a structure of a horizontal jacking cylinder plus a guide groove: the horizontal jacking cylinder is horizontally arranged at one end of the connecting rod platform 3, and the guide groove is arranged at the other end of the connecting rod platform 3, and the horizontal jacking cylinder pushes one end of the anchor rod 10 horizontally, so that the other end of the anchor rod 10 is lifted upward along the guide groove, thereby realizing the steering lifting of the anchor rod 10.

[0030] It should be noted that since the anchor rod 10 needs to be lifted upward by the steering lifting mechanism 4 after falling onto the rod connecting platform 3, in this embodiment, a certain lifting distance needs to be spaced between the rod connecting platform 3 and the outlet end of the material dropping channel 11. The maximum distance is the length of a single anchor rod, which can meet the height requirement of lifting the anchor rod 10 to an inclined or even vertical state.

[0031] As a specific implementation of the embodiment of the present invention, please refer to Figures 6 to 8The steering lifting mechanism 4 includes a lifting drive 42, a speed transmission assembly 43 and a support hook 41. The lifting drive 42 has a fixed end and a driving end extending downward; the speed transmission assembly 43 is connected to the driving end, and the speed transmission assembly 43 can be lifted and moved under the drive of the lifting drive 42, and can rotate under the drive of the lifting drive 42; the support hook 41 is connected to the speed transmission assembly 43, and can be lifted and lowered synchronously with the speed transmission assembly 43; wherein the support hook 41 is used to clamp on the end of the anchor rod 10 to drive the end of the anchor rod 10 to move upward.

[0032] In this embodiment, the speed transmission component 43 can adopt a transmission structure such as a chain transmission component, a belt transmission component or a gear rack transmission component, and the lifting drive 42 adopts a cylinder. The speed transmission component 43 can be lifted and moved under the drive of the lifting drive 42, and can also rotate under the drive of the lifting drive 42, thereby realizing the speed lifting of the hook 41, so that the end of the anchor rod 10 can be quickly lifted. For example, if the lifting speed of the driving end of the lifting drive 42 is 10 cm / s, the speed transmission component 43 can increase the lifting speed of the hook 41 to 20 cm / s or higher, and the specific multiple is determined according to the actual design and needs.

[0033] The support hook 41 is provided with a clamping structure, such as Figure 8 The slot shown in the figure can be connected to the drill bit end of the anchor rod 10 to ensure that the anchor rod 10 will not be separated from the hook 41 during the lifting process.

[0034] The application of the double-speed transmission assembly 43 speeds up the lifting speed of the end of the anchor rod 10, greatly shortening the delivery time of each anchor rod 10. At the same time, through the precise control of the lifting drive 42, the anchor rod 10 can be accurately lifted to the specified height and angle, thereby improving construction efficiency.

[0035] As a specific implementation of the embodiment of the present invention, please refer to Figures 6 to 8 The double-speed transmission assembly 43 includes a mounting plate 431, two sprockets 432 and a chain 433; the mounting plate 431 extends in the up-down direction, the upper end of the mounting plate 431 is slidably connected to the fixed end, and the lower end of the mounting plate 431 is connected to the driving end; the two sprockets 432 are respectively rotatably connected to one side of the mounting plate 431, and the two sprockets 432 are spaced apart in the up-down direction; the chain 433 is sleeved on the outer periphery of the two sprockets 432; wherein, a link of the chain 433 is fixedly connected to the fixed end through a first connecting member 434, and the support hook 41 is connected to the chain 433 through a second connecting member 435.

[0036] In this embodiment, the multiple speed transmission assembly 43 adopts a transmission structure of a sprocket 432 and a chain 433, and the mounting plate 431 provides a mounting carrier for the sprocket 432, so that the driving end of the lifting drive member 42 is connected to the lower end of the mounting plate 431, which can maximize the stroke of the hook 41. A link of the chain 433 is fixedly connected to the fixed end (cylinder wall) of the lifting drive member 42 through the first connecting member 434, so that when the driving end of the lifting drive member 42 drives the mounting plate 431 and the two sprockets 432 to rise and fall, the chain 433 will rotate relative to the sprocket 432, thereby realizing the self-rotation of the multiple speed transmission assembly 43. The maximum stroke of the hook 41 moving up and down is the sum of the stroke of the driving end and the distance between the two sprockets 432.

[0037] For the specific upgrade process, see Figure 6 and Figure 7 After the anchor rod 10 falls from the blanking channel 11 to the rod receiving platform 3 under the action of gravity, the lifting drive member 42 is started, and the driving end extends to drive the double-speed transmission component 43 and the support hook 41 to move downward, and at the same time, the chain 433 drives the support hook 41 to descend, so that the support hook 41 is engaged with the drill end of the anchor rod 10; then the driving end of the lifting drive member 42 retracts, driving the double-speed transmission component 43 to rise, and at the same time, the support hook 41 moves up with the chain 433, so that the support hook 41 drives the drill end of the anchor rod 10 to be quickly lifted.

[0038] By fixing one link of the chain 433 to the fixed end of the lifting drive 42, the lifting drive 42 drives the multiple speed transmission assembly 43 to lift and lower, and at the same time drives the relative rotation between the chain 433 and the sprocket 432, thereby achieving multiple speed lifting of the hook 41. The above structure eliminates the need for a rotating drive member for driving the sprocket 432 to rotate, simplifies the structure of the device, reduces production costs, and reduces the demand for electrical control.

[0039] As a specific implementation of the embodiment of the present invention, please refer to Figure 6 A plurality of parallel guide rollers 32 are rotatably connected to the connecting rod platform 3 , and the main axes of the guide rollers 32 are arranged parallel to the moving direction of the first plug plate 21 or the second plug plate 22 .

[0040] In the present embodiment, when the hook 41 drives the drill end of the anchor rod 10 to lift, the mounting end of the anchor rod 10 (the end opposite to the drill end) moves along the connecting rod platform 3 toward the side close to the steering and lifting mechanism 4. At this time, the setting of multiple guide rollers 32 can provide an interval support for the mounting end of the anchor rod 10, while reducing the wear between the anchor rod 10 and the connecting rod platform 3, thereby ensuring the delivery quality of the anchor rod 10 and extending the service life of the connecting rod platform 3.

[0041] As a specific implementation of the embodiment of the present invention, please refer to Figure 5 The receiving surface of the rod connecting platform 3 is set at an angle with the horizontal plane, and the end of the rod connecting platform 3 away from the rod bin 1 is connected with an arc-shaped guide plate 31, and the arc-shaped guide plate 31 extends outward and upward in an arc shape.

[0042] In this embodiment, the inclined setting of the receiving surface of the connecting rod platform 3 is utilized to make the anchor rod 10 also be inclined after falling, so as to meet the requirements of the subsequent transfer mechanism (such as a robot) for the docking angle of the anchor rod 10 in the feeding state.

[0043] Specifically, during the falling process of the anchor rod 10, the drill end of the anchor rod 10 first contacts the higher end of the rod receiving platform 3. At this time, the higher end of the rod receiving platform 3 receives the drill end of the anchor rod 10 and prevents it from moving further downward. The mounting end of the anchor rod 10 continues to move downward along the arc-shaped guide plate 31 to the lower end of the rod receiving platform 3 (i.e., the end away from the rod bin 1). Thus, the anchor rod 10 falls on the rod receiving platform 3 in an inclined state. The inclination angle of the rod receiving platform 3 is determined according to the needs of the on-site equipment. Furthermore, the rod receiving platform 3 can also be connected to an angle adjustment mechanism so that the inclination angle of the rod receiving platform 3 can be flexibly adjusted.

[0044] As a specific implementation of the embodiment of the present invention, please refer to Figure 1 The first plug plate 21 and the second plug plate 22 are connected through a linkage rod 25 , and the first plug plate 21 or the second plug plate 22 is connected to a horizontal driving member 26 .

[0045] In this embodiment, the horizontal driving member 26 adopts a cylinder, and the first plug plate 21 and the second plug plate 22 are connected as a whole through the connecting rod 25. Only one horizontal driving member 26 is needed to simultaneously control the insertion or removal of the first plug plate 21 and the second plug plate 22, which helps to save processing costs. At the same time, it can ensure the synchronization of the actions of the first plug plate 21 and the second plug plate 22, and ensure the reliable separation process of the anchor rod 10.

[0046] As a specific implementation of the embodiment of the present invention, please refer to Figure 4 A plurality of first plug boards 21 and second plug boards 22 are arranged at intervals in the up-down direction, and the first plug boards 21 and second plug boards 22 are arranged alternately in the up-down direction.

[0047] In this embodiment, multiple first plug plates 21 are connected by a first connecting rod 23, and multiple second plug plates 22 are connected by a second connecting rod 24, so that multiple first plug plates 21 or multiple second plug plates 22 can be inserted or removed synchronously. This structure helps to reduce the pressure when the second plug plates 22 are inserted, and at the same time increases the separation efficiency of the anchor rod 10.

[0048] Furthermore, the first connecting rod 23 and the second connecting rod 24 are also connected by a linkage rod 25, and the horizontal driving member 26 is connected to the first connecting rod 23 or the second connecting rod 24, so that the horizontal driving member 26 can simultaneously control the actions of multiple first plugboards 21 and multiple second plugboards 22.

[0049] Specifically, in this embodiment, the first plug board 21 and the second plug board 22 are each provided with three. Figure 4 The figure shows the process of alternately inserting the first plug plate 21 and the second plug plate 22 into the blanking channel 11 to separate the anchor rods 10: in the initial state, multiple anchor rods 10 are arranged in sequence up and down in the blanking channel 11. Now, multiple anchor rods 10 are defined as anchor rod ①, anchor rod ②, anchor rod ③, anchor rod ④... from bottom to top. The first plug plate 21 is inserted into the blanking channel 11 and supported under the anchor rod ①. At this time, the anchor rods above it are blocked and will not fall. Subsequently, the second plug plate 22 is inserted, and the top second plug plate 22 is inserted between anchor rod ① and anchor rod ②, and receives anchor rod ② and the anchor rods above it. At the same time, the first plug plate 21 is moved out, and anchor rod ① falls onto the second plug plate 22 in the middle position; afterwards, the first plug plate 21 is inserted, and the second plug plate 22 is moved out, and the top first plug plate 21 receives anchor rod ② and the anchor rods above it, and anchor rod ① falls onto the first plug plate 21 in the middle position; afterwards, the second plug plate 22 is inserted, and the first plug plate 21 is moved out, and the top second plug plate 22 receives anchor rod ③ and the anchor rods above it, and anchor rod ① falls onto the bottom second plug plate 22, and anchor rod ② falls onto the second plug plate 22 in the middle position; afterwards , the first plug plate 21 is inserted, the second plug plate 22 is moved out, the top first plug plate 21 receives anchor rod ③ and the anchor rods above it, anchor rod ① falls to the bottom first plug plate 21, and anchor rod ② falls to the first plug plate 21 in the middle; then, the second plug plate 22 is inserted, the first plug plate 21 is moved out, the top second plug plate 22 receives anchor rod ④ and the anchor rods above it, anchor rod ① breaks away from the support and falls, anchor rod ② falls to the bottom second plug plate 22, anchor rod ③ falls to the second plug plate 22 in the middle... and so on and so forth, the first plug plate 21 and the second plug plate 22 are alternately inserted into and moved out of the blanking channel 11, and one anchor rod is separated each time and made to fall, so as to realize the orderly separation of the anchor rods.

[0050] As a specific implementation of the embodiment of the present invention, please refer to Figure 7 and Figure 8 A guide slider 44 is connected to the fixed end, a boss 4311 slidably matched with the guide slider 44 is connected to the side wall of the mounting plate 431 , and the first connecting member 434 is connected to the side wall of the guide slider 44 .

[0051] In this embodiment, when the driving end of the lifting drive 42 drives the speed transmission assembly 43 to move up and down, the boss 4311 on the side wall of the mounting plate 431 can slide along the guide slider 44, thereby increasing the stability of the anchor rod 10 during lifting. Specifically, a T-slot 441 is provided on the guide slider 44, and the boss 4311 is a T-stage structure adapted to the T-slot 441. The boss 4311 slides with the T-slot 441 on the guide slider 44, which not only provides a guide for the up and down movement of the speed transmission assembly 43, but also prevents the mounting plate 431 from tilting outward due to force when lifting the anchor rod 10, thereby ensuring that the anchor rod 10 is lifted stably.

[0052] Furthermore, the portion of the boss 4311 located in the T-slot 441 can also be set as a rolling wheel structure. By rolling the rolling wheel in the T-slot 441, the sliding friction is converted into rolling friction, thereby reducing the friction resistance during the lifting and lowering process of the mounting plate 431.

[0053] The first connecting member 434 and the second connecting member 435 can adopt the structure of chain attachments in the prior art, and are respectively used to be connected to a link of the chain 433. The first connecting member 434 is connected to the side wall of the guide slider 44 through a connecting block to achieve a fixed connection between a link of the chain 433 and the fixed end of the lifting drive member 42.

[0054] As a specific implementation of the embodiment of the present invention, please refer to Figure 1 The insertion ends of the first plug plate 21 and the second plug plate 22 are both provided with a guide surface 211 which gradually inclines outward from bottom to top.

[0055] In this embodiment, the setting of the inclined guide surface 211 can reduce the collision and friction between the first plug plate 21 or the second plug plate 22 and the surrounding parts when being inserted into the blanking channel 11, so that the second plug plate 22 can be inserted more smoothly between two adjacent anchor rods 10, avoiding jamming and improving the convenience of operation. On the other hand, the inclined guide surface 211 can make the anchor rod 10 transition downward more orderly during the process of alternately inserting the first plug plate 21 or the second plug plate 22, ensuring the stability and continuity of the self-falling process of the anchor rod 10.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
