Description

Technical Field

[0001] The invention relates to a power supply device for providing power to tunneling equipment, and also relates to tunneling equipment. Background Art

[0002] In tunneling operations, tunneling equipment serves as the core equipment. Its operating modules primarily include the rock drilling module, anchoring module, and cleaning module. They also include a hydraulic station that powers the hydraulic cylinders within these modules, and a camera module for capturing images. The proper operation of these components, including the rock drilling module, requires a continuous and stable power supply. Currently, underground power supply primarily utilizes a combination of fixed power stations and mobile cables. Fixed power stations are installed at regular intervals within the tunnel, and power is transmitted to the tunneling equipment via cables.

[0003] However, this traditional power supply method has numerous technical drawbacks in practical application. As tunneling operations progress, the distance between the tunneling equipment and the fixed power station gradually increases. When the cable reaches its limit, the cable must be manually disconnected, reeled in, and reconnected to the next nearest power station. During power outages, the tunneling equipment cannot function properly, directly impacting tunneling progress and increasing project costs. Furthermore, disconnection and reconnection operations are labor-intensive, cumbersome, and pose safety risks. Furthermore, frequent power outages can impact the tunneling equipment's electrical system, potentially leading to reduced insulation performance and accelerated component aging, impacting equipment reliability and service life.

[0037] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the embodiments described are only a part of the embodiments of the present invention, rather than all the embodiments.

[0038] Example 1

[0039] This embodiment describes a mobile power supply device for underground metal mines used for mobile power supply in tunneling equipment:

[0040] like Figure 1 and Figure 8 The portable power supply device 9 includes a mobile chassis 901 , a lifting seat 903 , a telescopic cylinder 902 , a downward connecting mechanism 73 , a brush mechanism 904 and a cable reel 905 .

[0041] The mobile chassis 901 is preferably remote-controlled.

[0042] The lifting seat 903 cooperates with the vertical slide rail on the mobile chassis 901 , and one end of the telescopic cylinder 902 is connected to the mobile chassis 901 and the other end is connected to the lifting seat 903 .

[0043] The downward connecting mechanism 73 is installed at the bottom of the flat plate part of the lifting seat 903 and is columnar, and is used to cooperate with the connecting hole on the tunneling equipment body 1 to be powered; a first electrical connection contact is provided on the downward connecting mechanism 73.

[0044] The downward connection mechanism 73 includes a second connecting column 731, a second multi-stage cylinder 732, a second connecting rod 733, a second intermediate sliding plate 734, and a second terminal sliding plate 735. The upper end of the second connecting column 731 is fixedly connected to the flat plate portion via a plurality of parallel second connecting rods 733. The second multi-stage cylinder 732 is mounted within the second connecting column 731, with its telescopic rod facing the flat plate portion. The first telescopic rod of the second multi-stage cylinder 732 is connected to the second terminal sliding plate 735, and the second telescopic rod is connected to the second intermediate sliding plate 734. The second intermediate sliding plate 734 is located between the second terminal sliding plate 735 and the second connecting column 731. The second connecting rod 733 passes through the second intermediate sliding plate 734 and the second terminal sliding plate 735, slidingly connecting them. The second intermediate sliding plate 734 has a concave tapered surface on its outer edge near the second terminal sliding plate 735. The inner wall of the connection hole on the vehicle body 1 is provided with a working groove, into which the second locking block 102 is rotatably mounted. The inner edge of the second locking block 102 is provided with a notch for mating with the outer edge of the tapered surface. A first oil port is provided on the lower end surface of the second connecting post 731, which is connected to the second multi-stage oil cylinder 732. A first electrical contact is also provided on the lower end surface of the second connecting post 731.

[0045] A second electrical connection contact is provided in the connection hole corresponding to the downward connection mechanism 73. The second electrical connection contact corresponds to the position of the first electrical connection contact and is connected to the main power supply system on the vehicle body 1 for supplying power to the entire tunneling equipment.

[0046] The brush mechanism 904 and cable drum 905 are both mounted on the mobile chassis 901. One end of the cable on the cable drum 905 is connected to an electrical ring on the drum 905 that rotates synchronously with the cable, and the other end is used to connect to the power supply station. The brush mechanism 904 and the electrical ring are electrically connected through contact. The brush mechanism 904 also electrically connects to the first electrical connection contact in the downward connection mechanism 73 via the connecting cable.

[0047] The portable power supply device 9 can be freely moved to the side of the excavation equipment that needs to be powered. After the lifting seat 903 is upgraded, the downward connecting mechanism 73 is aligned with the connecting hole on the vehicle body 1, and then the lifting seat 903 is dropped to insert the downward connecting mechanism 73. The second multi-stage oil cylinder 732 is in a retracted state. Since the second locking block 102 is rotatable and the center of gravity is located outside the rotation point, the second locking block 102 will not play a blocking role, and the inner side will contact the second connecting column 731, the second intermediate sliding disk 734 and the second end sliding disk 735 in sequence. When the lower end of the second connecting column 731 touches the lower end of the second connecting hole (which can be detected by a pressure sensor or directly by the contacts here), the second oil circuit interface injects hydraulic oil into the second multi-stage oil cylinder 732 through the first oil circuit interface, and the first-stage telescopic rod drives the second end sliding disk 735 to move first, so that a gap appears between the second end sliding disk 735 and the second intermediate sliding disk 734. At this time, the inner end of the second locking block 102 enters the gap under the action of its own weight, and then the second-stage telescopic rod begins to drive the second intermediate sliding disk 734 to move, so that the outer edge of the conical surface on the second intermediate sliding disk 734 engages with the upward-facing notch on the second locking block 102. This engagement prevents the second locking block 102 from rotating and blocks the second intermediate sliding disk 734 from continuing to move, thereby firmly fixing the second connecting column 731 in the second connecting hole through the hydraulic internal force, and the first electrical connection contact and the second electrical connection contact complete close contact, thereby realizing the electrical and mechanical connection between the mobile power supply device 9 and the vehicle body 1. After the telescopic cylinder 902 is further shortened, the entire accompanying power supply device 9 can be raised to facilitate free movement with the vehicle body 1. During the advancement of the excavation equipment, the rotating cable drum 905 can automatically release the cable to achieve uninterrupted power supply.

[0048] To remove the portable power supply unit 9, the telescopic cylinder 902 is gradually extended, causing the mobile chassis 901 to land first. The oil supply to the second multi-stage oil cylinder 732 is then disconnected, and the telescopic cylinder 902 continues to extend. As the second multi-stage oil cylinder 732 automatically returns to its original position, the second locking block 102 is withdrawn, disconnecting the downward connecting mechanism 73. The entire downward connecting mechanism 73 can then be removed. At this point, the portable power supply unit 9 can move freely.

[0049] Example 2

[0050] like Figure 1 and 2 This embodiment provides a tunneling device, including a vehicle body 1, with a traveling mechanism provided at the bottom of the vehicle body 1. The traveling mechanism may be a crawler-type or a wheel-type. The tunneling device also includes the metal mine underground accompanying power supply device of the first embodiment.

[0051] A camera module 2 is installed on the top of the vehicle body 1. The camera module 2 includes a camera installed on a pan-tilt platform, which is used to shoot the operating surface and upload the image to the server for storage and recognition processing.

[0052] A plurality of working modules are mounted on the vehicle body 1 , each of which includes a robotic arm (working part) and a connector connected to the root of the robotic arm. The connector is detachably connected to the vehicle body 1 via a connecting mechanism.

[0053] Furthermore, the working modules are divided into two categories: an operating module for performing tunneling operations and a supporting module for supporting the entire modular metal mine tunneling equipment.

[0054] The operation module includes a rock drilling module 3 and a hydraulic blasting module 8 installed at the front end of the vehicle body 1, and also includes a cleaning module 6 and an anchor protection module 7 installed at the rear end of the vehicle body 1, thereby achieving multiple uses of one machine. Figure 6 The drilling module 3 includes a drilling arm 301 with a drilling mechanism at its end for drilling blastholes on the operating surface. The hydraulic blasting module is used to perform fracturing and separation on the drilled blastholes. The cleaning module 6 is equipped with a rotatable cleaning head for clearing pumice from collapsed areas after blasting. The rear end of the vehicle body 1 is also equipped with an anchor support module 7 for drilling and inserting anchor holes, as well as for supporting and securing anchor nets to the anchors.

[0055] It should be noted that the robotic arms and actuators of each operating module can utilize existing products. For example, the Sandvik DD311 can be used as the main body of the rock drilling module, the Lead Road and Mine PL1500 can be used as the main body of the hydraulic blasting module, the Sandvik MB670-1 can be used as the main body of the cleaning module, and the Sandvik DS311 can be used as the main body of the anchoring module. Other models of mechanical components can also be selected according to on-site working conditions during implementation, and the specific structures are not detailed here.

[0056] Furthermore, the vehicle body 1 is also provided with a silo for storing anchoring materials.

[0057] The support module includes two left and right groups of crawling drilling modules 4 installed at the front end of the vehicle body 1 and two left and right groups of crawling support modules 5 installed at the rear end of the vehicle body 1 .

[0058] like Figure 1 、 Figure 2 、 Figure 3 and Figure 5The structures of the crawling drilling module 4 and the crawling support module 5 are basically the same: they both include a first connector 292, a lifting and lowering mechanism, a rotating telescopic arm 806, a deflection hydraulic cylinder 805, a first rotating joint 807, a second rotating joint 808 and a drill bit 810, which are connected in sequence from the vehicle body 1 (root) to the end.

[0059] The first connector 292 is connected to the vehicle body 1. The lifting and lowering mechanism is installed on the first connector 292. The lifting and lowering mechanism includes a first connecting arm 802, a second connecting arm 803, a lifting and lowering hydraulic cylinder 801 and a connecting seat 804. The first connecting arm 802 and the second connecting arm 803 are of equal length and arranged in parallel. The roots of both are rotatably connected to the first connector 292, and the ends are rotatably connected to the connecting seat 804, forming a parallelogram mechanism to ensure that the rear end components always remain horizontal during lifting and lowering. One end of the lifting and lowering hydraulic cylinder 801 is rotatably connected to the first connector 292, and the other end is rotatably connected to the first connecting arm 802 or the second connecting arm 803, and the driving control of lifting and lowering is achieved through telescoping.

[0060] The base of the rotating telescopic arm 806 is rotatably connected to the connecting base 804 to enable left and right rotation relative to the landing mechanism. A deflection hydraulic cylinder 805 is rotatably connected to the connecting base 804 at one end and to the arm body of the rotating telescopic arm 806 at the other end to drive the rotating telescopic arm 806 to rotate left and right relative to the landing mechanism.

[0061] The front end of the telescopic portion of the rotating telescopic arm 806 is connected to the first rotating joint 807. The rotation axis of the first rotating joint 807 is parallel to the direction of extension and retraction of the rotating telescopic arm 806 and is used to adjust the angle of the end. The rotation axis of the second rotating joint 808 is perpendicular to the rotation axis of the first rotating joint 807 and is used to drive the drill bit 810 to rotate.

[0062] In this embodiment, the crawling drilling module 4 and the crawling support module 5 differ in that the drill bit 810 of the crawling drilling module 4 is connected to the second rotary joint 808 via a rotary drive device, and the drill bit 810 is rotatable for drilling. The drill bit 810 of the crawling support module is directly connected to the second rotary joint 808 and is non-rotatable, serving only as support. As an alternative embodiment, the crawling support module 5 can also be rotatable, i.e., the structure is identical to that of the crawling drilling module 4.

[0063] Furthermore, a rolling support module 809 is provided at the bottom of the rotating telescopic arm 806 or the first rotating joint 807 or the second rotating joint 808 to reduce the resistance encountered when moving along the crawling track 100 .

[0064] Furthermore, the vehicle body 1 is also provided with a general control system, a general power supply system and a general hydraulic station.

[0065] Example 3

[0066] This embodiment describes the excavation method of the excavation equipment in the second embodiment, which includes the following steps:

[0067] Step 1: Set the lifting and lowering mechanisms of the crawling drilling module 4 and the crawling support module 5 to the raised state, so that the rotating telescopic arm 806 and the drill bit 810 leave the ground, and then drive the excavation equipment to the working starting position.

[0068] Step 2: Rotate the telescopic arms 806 of the two crawling drilling modules 4 toward the corresponding side rock walls, then extend the telescopic arms 806, start the drill bit 810 at the end of the crawling drilling module 4, and at the same time control the metal mine climbing tunneling equipment to continue moving forward, processing groove-shaped crawling tracks 100 on the rock walls on both sides.

[0069] Furthermore, when processing the crawling track 100, the metal mine top climbing tunneling equipment stops moving forward at every interval, and then the second rotating joint 808 of the crawling drilling module 4 adjusts the angle of the connected drill bit 810 and drills a positioning hole of a hole structure deep into the rock wall. Then the second rotating joint 808 controls the drill bit 810 to return to the original direction, and the metal mine top climbing tunneling equipment continues to move forward.

[0070] Step 3: When the end of the crawling support module 5 is in front of the starting end of the crawling track 100, the metal mine top-climbing tunneling equipment stops moving. The telescopic arms 806 of the two crawling support modules 5 are rotated toward the corresponding rock face. The telescopic arms 806 are then extended, and the drill bits 810 of the crawling support modules 5 are inserted into the crawling track 100. The lifting and lowering mechanisms of the crawling drilling module 4 and the crawling support module 5 are then set to the lowering state (this refers to the telescopic arms 806 and their end portions falling relative to the vehicle body 1, not the vehicle body 1 itself). This allows the crawling tracks 100 on both sides to support the vehicle body 1, raising the bottom of the vehicle body 1 off the ground and leaving space below. Other equipment and vehicles can then reach the operating surface from the bottom of the vehicle body 1 to conduct operations, significantly improving production efficiency.

[0071] Step 4: The crawling drilling module 4 and crawling support module 5 achieve telescopic drilling and crawling along the crawling track 100. During the crawling process, the front rock drilling module 3 and hydraulic blasting module 8 perform rock drilling and blasting operations on the operating surface. Simultaneously, the cleaning module 6 installed at the rear end of the vehicle body 1 cleans the rock wall, and the anchoring module 7 installed at the rear end of the vehicle body 1 anchors the rock wall.

[0072] The telescopic drilling crawling method refers to the alternating execution of action A and action B:

[0073] Action A: The second rotating joint 808 of the crawling support module 5 adjusts the angle of the connected drill bit 810 and inserts it into the positioning hole in the crawling track 100. The rotating telescopic arms 806 of the crawling drilling module 4 and the crawling support module 5 then begin to extend simultaneously, and the drill bit 810 of the crawling drilling module 4 rotates, machining the crawling track 100 forward using the positioning hole in which the crawling support module 5 was inserted as a support point. While machining the crawling track 100 forward, the rotating telescopic arms 806 of the crawling drilling module 4 and the crawling support module 5 stop extending at intervals. The second rotating joint 808 of the crawling drilling module 4 then adjusts the angle of the connected drill bit 810, drilling a positioning hole deep into the rock wall. The second rotating joint 808 then controls the drill bit 810 to return to its original orientation, and the rotating telescopic arms 806 of the crawling drilling module 4 and the crawling support module 5 continue to extend until they reach their maximum length.

[0074] Action B: The second rotating joint 808 of the crawling drilling module 4 adjusts the angle of the connected drill bit 810 and drills a positioning hole of a hole structure deep into the rock wall. Then, the second rotating joint 808 of the crawling support module 5 adjusts the angle of the connected drill bit 810 and withdraws the drill bit 810 from the currently inserted positioning hole. Then, the rotating telescopic arms 806 of the crawling drilling module 4 and the crawling support module 5 are shortened at the same time, and the metal mine climbing top excavation equipment is dragged forward with the positioning hole in which the crawling drilling module 4 is inserted as the support point until the drill bit 810 of the crawling support module 5 reaches the position corresponding to a certain positioning hole.

[0075] Through the above-mentioned telescopic drilling and crawling method, long-distance continuous crawling can be achieved, laying the foundation for continuous operation.

[0076] It should be noted that when the telescopic arm 806 is extended and retracted, the hydraulic cylinder 805 can be deflected to ensure that the end of the telescopic arm 806 is always located in the crawling track 100 to avoid falling off or being blocked.

[0077] Furthermore, when the metal mine top-climbing tunneling equipment is operating, the drill bits 810 of the crawling drilling module 4 and the crawling support module 5 are inserted into the positioning holes, providing stable horizontal support. By drilling positioning holes at intervals in the crawling track 100, the equipment is provided with horizontal force support points, which not only ensures smooth drilling of the crawling track 100 but also provides stable support for tunneling operations.

[0078] Example 4

[0079] This embodiment describes the specific structure of the connection mechanism used to connect the connecting body of each working module with the vehicle body 1 in the second embodiment.

[0080] A modular connecting mechanism for a robotic arm is used to connect a base (i.e., the vehicle body 1) to a connecting body to which the robotic arm is connected. The mechanism comprises a connecting column, a multi-stage oil cylinder, a connecting rod, an intermediate sliding plate, and an end sliding plate.

[0081] One end of the connecting column is fixedly connected to the connecting body via multiple parallel connecting rods. The multi-stage hydraulic cylinder is a single-acting, spring-return hydraulic cylinder installed in the connecting column. Its telescopic rod faces the connecting body. The first telescopic rod of the multi-stage hydraulic cylinder is connected to the terminal sliding plate, and the second telescopic rod is connected to the intermediate sliding plate. The intermediate sliding plate is located between the terminal sliding plate and the connecting column, and the connecting rod passes through the intermediate sliding plate and the terminal sliding plate, slidingly connecting them.

[0082] The middle sliding plate is provided with a concave tapered surface at an outer edge close to the end sliding plate.

[0083] The base is provided with a connecting hole that cooperates with the axial hole of the connecting column, and the inner wall of the connecting hole is provided with a working groove. A locking block is installed in the working groove through a rotating connection, and the inner edge of the locking block is provided with a notch for cooperating with the outer edge of the conical surface.

[0084] A first oil circuit interface is provided on the other end surface of the connecting column, and the first oil circuit interface is connected to the multi-stage oil cylinder.

[0085] The modular connection mechanism for the robotic arm also includes a connecting cable. A first electrical connection contact is provided on the other end surface of the connecting post. One end of the connecting cable is connected to the first electrical connection contact. The connecting cable passes through the connecting post and the connecting rod, and the other end is used to connect to the electrical components inside the connector.

[0086] In this embodiment, Figure 3 、 Figure 4 、 Figure 6 and Figure 7 The first connector 292 in the support module is connected to the vehicle body 1 via an upward connecting mechanism 72, and the second connector 392 in the operation module is connected to the vehicle body 1 via a downward connecting mechanism 73. Both the upward connecting mechanism 72 and the downward connecting mechanism 73 are modular connecting mechanisms of the robotic arm. The first connector 292 and the second connector 392 also respectively contact and mate with the vertical outer surface of the vehicle body 1.

[0087] Specifically, if Figure 4The upward connecting mechanism 72 includes a first connecting post 721 as the connecting post, a first multi-stage oil cylinder 722 as the multi-stage oil cylinder, a first connecting rod 723 as the connecting rod, a first intermediate sliding disk 724 as the intermediate sliding disk, and a first end sliding disk 725 as the end sliding disk. The first connecting hole on the vehicle body 1 that matches the first connecting post 721 is arranged downward. A plurality of first locking blocks 101 evenly distributed around the circumference are correspondingly arranged in the first connecting hole. A first electrical connection contact and a first oil circuit interface are provided at the upper end of the first connecting post 721. A second electrical connection contact corresponding to the first electrical connection contact and a second oil circuit interface corresponding to the first oil circuit interface are provided at the upper end of the first connecting hole.

[0088] When connecting the modules, a lifting device is required to assist.

[0089] Before the support module is inserted upward, the first multi-stage cylinder 722 is in a retracted state. During insertion, since the first locking block 101 is rotatable and its center of gravity is located outside the rotation point, the first locking block 101 does not act as a barrier, and its inner side contacts the first connecting column 721, the first intermediate sliding plate 724, and the first end sliding plate 725 in sequence. When the upper end of the first connecting column 721 touches the upper end of the first connecting hole (which can be detected by a pressure sensor or directly detected by the contacts here), the second oil circuit interface injects hydraulic oil into the first multi-stage oil cylinder 722 through the first oil circuit interface, and the first-stage telescopic rod drives the first end sliding disk 725 to move first, so that a gap appears between the first end sliding disk 725 and the first intermediate sliding disk 724. At this time, the inner end of the first locking block 101 enters the gap under the action of its own weight, and then the second-stage telescopic rod begins to drive the first intermediate sliding disk 724 to move, so that the outer edge of the conical surface on the first intermediate sliding disk 724 engages with the upward groove on the first locking block 101. This engagement prevents the first locking block 101 from rotating and blocks the first intermediate sliding disk 724 from continuing to move, thereby firmly fixing the first connecting column 721 in the first connecting hole through the hydraulic internal force.

[0090] Similarly, if Figure 7 The downward connecting mechanism 73 includes a second connecting post 731 serving as the connecting post, a second multi-stage oil cylinder 732 serving as the multi-stage oil cylinder, a second connecting rod 733 serving as the connecting rod, a second intermediate sliding disk 734 serving as the intermediate sliding disk, and a second terminal sliding disk 735 serving as the terminal sliding disk. A second connecting hole on the vehicle body 1 that cooperates with the second connecting post 731 is disposed upward. A plurality of second locking blocks 102 evenly distributed around the circumference are correspondingly disposed in the second connecting hole. A first electrical connection contact and a first oil circuit interface are disposed at the lower end of the second connecting post 731. A second electrical connection contact corresponding to the first electrical connection contact and a second oil circuit interface corresponding to the first oil circuit interface are disposed at the lower end of the second connecting hole.

[0091] Before the working module is inserted downward, the second multi-stage cylinder 732 is in a retracted state. During insertion, since the second locking block 102 is rotatable and its center of gravity is located outside the rotation point, it does not act as a barrier and its inner side contacts the second connecting column 731, the second intermediate sliding plate 734, and the second end sliding plate 735 in sequence. When the lower end of the second connecting column 731 touches the lower end of the second connecting hole (which can be detected by a pressure sensor or directly detected by the contacts here), the second oil circuit interface injects hydraulic oil into the second multi-stage oil cylinder 732 through the first oil circuit interface, and the first-stage telescopic rod drives the second end sliding disk 735 to move first, so that a gap appears between the second end sliding disk 735 and the second intermediate sliding disk 734. At this time, the inner end of the second locking block 102 enters the gap under the action of its own weight, and then the second-stage telescopic rod begins to drive the second intermediate sliding disk 734 to move, so that the outer edge of the conical surface on the second intermediate sliding disk 734 engages with the upward groove on the second locking block 102. This engagement prevents the second locking block 102 from rotating and blocks the second intermediate sliding disk 734 from continuing to move, thereby firmly fixing the second connecting column 731 in the second connecting hole through the hydraulic internal force.

[0092] After the middle sliding disk is engaged with the locking block, it can not only firmly fix the connecting column in the connecting hole, but also ensure close contact of the electrical connection contacts, thereby ensuring the stability of signal transmission.

[0093] The main hydraulic station is connected to the second oil circuit interface and is only responsible for providing hydraulic power to the multi-stage oil cylinders of each connecting mechanism. When disconnection is required, the oil supply to the multi-stage oil cylinders can be disconnected and the module can be removed by the lifting device.

[0094] After achieving modular connection of the mechanical parts through the above structure, it is also necessary to realize electrical connection and hydraulic functions within each module:

[0095] The first connector 292 and the second connector 392 are both provided with a sub-hydraulic station and a sub-control system; the sub-hydraulic station is used to provide hydraulic power to the module; the sub-control system is electrically connected to the sub-hydraulic station and is used to control the operation of the sub-hydraulic station.

[0096] The connecting cables include power cables and signal cables, each of which has one end connected to a corresponding first electrical connection contact. The other end of the power cable is connected to the sub-control system and sub-hydraulic station for power supply, while the other end of the signal cable is connected to the sub-control system and sub-hydraulic station for signal transmission. The overall control system is connected to the second electrical connection contacts corresponding to each signal cable to transmit signals between modules, and the overall power supply system is connected to the second electrical connection contacts corresponding to each power cable to provide power to each module.

[0097] The present invention realizes a pure electric control connection between the vehicle body 1 and the working module by arranging a sub-control system and a sub-hydraulic station in the connecting body and transmitting power and signals through contacts, eliminating the complex hydraulic connection pipelines between the vehicle body 1 and the working module, further improving the connection efficiency and reducing the difficulty of operation.

[0098] It should be noted that it is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. The scope of the present invention is defined by the claims rather than the foregoing description.
