Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a longitudinal reinforcement buffer and automatic reinforcement threading device for a steel column cage. Background Technology

[0002] In modern building components, the binding of reinforced concrete column cages is gradually moving towards factory prefabrication, with automated machine binding replacing manual on-site work. Reinforced concrete column cages are mainly formed by binding longitudinal bars and stirrups. The longitudinal bars in the cage generally have one or two specifications, and the binding process typically requires a longitudinal bar buffer device.

[0003] In existing technologies, longitudinal steel bars are generally buffered using a single transverse chain or vertical chain, rarely buffering longitudinal bars of different specifications in different areas; or two independent chain devices are used, with the two devices being fed and unloaded separately through a scaffold, which occupies a large space, has a complex mechanism, and is costly. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, a longitudinal reinforcement buffer and automatic reinforcement threading device for reinforced column cages is provided to solve the problem that existing reinforced column cages cannot buffer longitudinal reinforcements of various specifications during the binding process.

[0005] To achieve the above objectives, a longitudinal reinforcement buffer and automatic reinforcement threading device for a reinforced column cage is provided, comprising:

[0006] frame;

[0007] The feeding mechanism includes two buffer racks that are staggered vertically. Each buffer rack includes two vertically arranged drive sprockets and a chain sleeved on the two drive sprockets. Multiple support hooks are connected to the outer side of the chain. The multiple support hooks are spaced apart along the length of the chain. One buffer rack is installed on the side of the frame, and the other buffer rack is located diagonally above the side of the first buffer rack away from the frame.

[0008] A multi-segment feeding rack includes a first lower slide and a first upper slide mounted on the lower side of the side of the frame. The first lower slide and the first upper slide are respectively inclined. The lower side of the first lower slide is aligned with the lower end of the chain of a buffer rack, and the lower side of the first upper slide is aligned with the lower end of another buffer rack. The upper side of the first lower slide extends to below the lower side of the first upper slide.

[0009] Multiple threading mechanisms are provided, and the top of the frame is covered with guide rails, with the multiple threading mechanisms being adjustablely mounted on the guide rails;

[0010] A multi-segment unloading rack includes a second sliding platform and a second upper sliding platform mounted on the upper side of the side of the frame. The second sliding platform and the second upper sliding platform are respectively inclined. The upper side of the second sliding platform is aligned with the upper end of the chain of a buffer rack, and the lower side of the second upper sliding platform is aligned with the upper end of the other buffer rack. The upper side of the second sliding platform extends to the lower side of the second upper sliding platform.

[0011] After the first specification longitudinal rib is inserted into the first upper slide, the first specification longitudinal rib falls into the support hook of the other buffer rack via the lower side of the first upper slide. The drive sprocket of the other buffer rack rotates to input the first specification longitudinal rib into the second upper slide via the upper end of the chain. The first specification longitudinal rib falls into the threading mechanism via the second lower slide.

[0012] After the second-specification longitudinal rib is inserted into the first upper slide, the drive sprocket of the other buffer rack is shut off so that a material drop gap is formed between the support hook at the lower end of the other buffer rack and the first upper slide. The second-specification longitudinal rib falls into the first lower slide through the material drop gap, and then falls into the support hook at the lower end of the chain of the buffer rack through the lower side of the first lower slide. The drive sprocket of the buffer rack rotates to input the second-specification longitudinal rib into the second lower slide through the upper end of the chain. The second-specification longitudinal rib falls into the threading mechanism through the second lower slide.

[0013] After the first or second specification longitudinal bar falls onto the bar threading mechanism, the bar threading mechanism adjusts its position and delivers the first or second specification longitudinal bar, so that the first or second specification longitudinal bar is threaded into the steel column cage.

[0014] Furthermore, a fixed baffle is installed on the lower side of the first sliding platform, and the fixed baffle and the first sliding platform form a notch for the support hook of the lower end of the chain of the buffer rack to pass through.

[0015] Furthermore, a movable baffle is rotatably mounted on the lower side of the second sliding platform, and a drive member for driving the movable baffle is hinged between the movable baffle and the top of the frame.

[0016] Furthermore, the driving component is an electro-hydraulic push rod.

[0017] Furthermore, the guide rail is arranged along the width direction of the frame, and the buffer rack is arranged on the side of the frame in the width direction.

[0018] Furthermore, the threading mechanism includes:

[0019] The support beam is slidably mounted on the guide rail;

[0020] Multiple conveying rollers are rotatably mounted on the support beam. The multiple conveying rollers are arranged along the length direction of the support beam. The circumferential surface of the conveying rollers forms a limiting groove. The limiting grooves of the multiple conveying rollers are connected to form an accommodating space for accommodating the first specification longitudinal rib or the second specification longitudinal rib.

[0021] A first drive assembly for driving the plurality of conveying rollers is mounted on the support beam;

[0022] A second drive assembly for driving the support beam is mounted on the guide rail.

[0023] Furthermore, the support beam is arranged along the length of the frame.

[0024] Furthermore, the first driving component includes:

[0025] The rotating shaft is provided with a plurality of shaft holes in the support beam, and the rotating shaft is rotatably inserted in each of the shaft holes. The roller is coaxially mounted on one end of the rotating shaft.

[0026] A drive sprocket, with the other end of each of the aforementioned shafts coaxially connected to the drive sprocket, and a chain sleeved on the outside of the plurality of drive sprockets;

[0027] A first motor is installed on the support beam, and the output end of the first motor is connected to a transmission sprocket.

[0028] Furthermore, the second driving component includes:

[0029] Gears, rotatably supporting beams;

[0030] A rack is mounted on the guide rail, and the rack meshes with the gear;

[0031] A second motor is mounted on the support beam, and the output end of the second motor is connected to the gear.

[0032] This invention provides a method for threading longitudinal reinforcement in a reinforced column cage using a longitudinal reinforcement buffer and an automatic reinforcement threading device, comprising the following steps:

[0033] Multiple first-specification longitudinal ribs are inserted into the first upper sliding platform;

[0034] The drive sprocket of the other buffer rack rotates, and the multiple first-specification longitudinal ribs fall onto the multiple support hooks of the other buffer rack via the lower side of the first upper slide to achieve buffering of the multiple first-specification longitudinal ribs.

[0035] The drive sprocket of the other buffer rack rotates to input the first specification longitudinal ribs into the second upper slide via the upper end of the chain;

[0036] The first-specification longitudinal rib falls into the rib-threading mechanism via the second sliding platform;

[0037] After the first-specification longitudinal bar falls onto the bar threading mechanism, the bar threading mechanism adjusts its position and delivers the first-specification longitudinal bar so that the first-specification longitudinal bar is threaded into the steel column cage.

[0038] After the second-specification longitudinal rib is inserted into the first upper slide, the drive sprocket of the other buffer rack is shut off so that a material dropping gap is formed between the support hook at the lower end of the other buffer rack and the first upper slide.

[0039] The second specification longitudinal rib is dropped into the first sliding table through the dropping gap, and then dropped into the support hook at the lower end of the chain of the buffer rack through the lower side of the first sliding table.

[0040] The drive sprocket of the buffer rack rotates to input the second specification longitudinal rib into the second sliding table via the upper end of the chain;

[0041] The second-specification longitudinal reinforcement falls into the reinforcement threading mechanism via the second sliding platform;

[0042] After the second-specification longitudinal bar falls onto the bar threading mechanism, the bar threading mechanism adjusts its position and delivers the second-specification longitudinal bar so that the second-specification longitudinal bar is threaded into the steel column cage.

[0043] The beneficial effects of this invention are that the longitudinal reinforcement buffer and automatic rebar threading device for the steel column cage of this invention specifically has the functions of automatic feeding, buffering, and discharging of longitudinal reinforcement, enabling buffering of two different specifications of longitudinal reinforcement. The dual buffer mechanism (buffer rack) of the longitudinal reinforcement buffer and automatic rebar threading device for the steel column cage of this invention has the same feed inlet, reducing the number of work stations. The longitudinal reinforcement buffer and automatic rebar threading device for the steel column cage of this invention enables two rebar threading mechanisms to simultaneously pick up and feed materials.

[0055] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0056] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0057] Reference Figures 1 to 10 As shown, the present invention provides a longitudinal reinforcement buffer and automatic reinforcement threading device for a steel column cage, comprising: a frame 1, a feeding mechanism 2, a multi-section feeding frame 3, multiple reinforcement threading mechanisms 4, and a multi-section unloading frame 5.

[0058] In this embodiment, the frame 1 is a rectangular frame structure. Specifically, the feeding mechanism 2 includes two sets of buffer racks 21.

[0059] The two sets of buffer racks 21 are staggered vertically, meaning that the height of one buffer rack is set first to the height of the other buffer rack.

[0060] The buffer rack 21 includes two drive sprockets 211 and a chain 212. The two drive sprockets 211 are arranged vertically. The chain 212 is sleeved on the two drive sprockets 211. Multiple support hooks 213 are connected to the outer side of the chain. The support hooks are located on the outer side of the outer surface of the chain.

[0061] Multiple support hooks 213 are spaced apart along the length of the chain. A buffer rack 21 is installed on the side of the frame 1. Another buffer rack 21 is located diagonally above the side of the buffer rack 21 away from the frame 1.

[0062] The multi-section feed rack 3 includes a first sliding slide 31 and a first upper slide 32 mounted on the lower side of the side of the frame 1.

[0063] The first sliding platform 31 and the first upper sliding platform 32 are respectively inclined. The lower side of the first sliding platform 31 is aligned with the lower end of the chain of a buffer rack 21. The lower side of the first upper sliding platform 32 is aligned with the lower end of another buffer rack 21. The upper side of the first sliding platform 31 extends below the lower side of the first upper sliding platform 32.

[0064] There are multiple threading mechanisms 4. In this embodiment, there are two threading mechanisms 4.

[0065] The top of the frame 1 is covered with guide rails 11. Multiple rib-threading mechanisms 4 are mounted on the guide rails 11 in adjustable positions.

[0066] The multi-section unloading rack 5 includes a second sliding platform 51 and a second upper sliding platform 52 mounted on the upper side of the side of the frame 1.

[0067] The second sliding platform 51 and the second upper sliding platform 52 are respectively inclined. The upper side of the second sliding platform 51 is aligned with the upper end of the chain of a buffer rack 21. The lower side of the second upper sliding platform 52 is aligned with the upper end of another buffer rack 21. The upper side of the second sliding platform 51 extends to below the lower side of the second upper sliding platform 52.

[0068] Multiple reinforcing bar threading mechanisms are located at the top of the frame. A feeding mechanism is located in the middle of the side of the frame. A multi-section feeding rack is located below the side of the frame. A multi-section feeding rack is located above the side of the frame. The longitudinal reinforcing bars of the steel column cage are fed into the feeding mechanism from the multi-section feeding rack, and then fed into the threading mechanism via the multi-section unloading rack. The threading mechanism feeds the longitudinal reinforcing bars into the steel column cage.

[0069] Specifically, the longitudinal reinforcement buffer and automatic reinforcement threading device of the present invention can simultaneously buffer or transport longitudinal reinforcement of two specifications and models of steel column cages.

[0070] See Figure 9 and Figure 10The longitudinal reinforcement of a steel column cage includes first-specification longitudinal reinforcement and second-specification longitudinal reinforcement. The diameter and other specifications of the first-specification longitudinal reinforcement and the second-specification longitudinal reinforcement are different.

[0071] See Figure 9 As shown, after the first-specification longitudinal rib 6 is inserted into the first upper slide 32, the first-specification longitudinal rib 6 falls through the lower side of the first upper slide 32 into the support hook 213 of another buffer rack 21. The drive sprocket 211 of the other buffer rack 21 rotates to input the first-specification longitudinal rib 6 through the upper end of the chain into the second upper slide 52. The first-specification longitudinal rib 6 falls through the second lower slide 51 into the rib threading mechanism 4.

[0072] See Figure 10 As shown, after the second-specification longitudinal rib 7 is inserted into the first upper slide table 32, the drive sprocket 211 of the other buffer rack 21 is shut off so that a material dropping gap is formed between the support hook 213 at the lower end of the other buffer rack 21 and the first upper slide table 32. Figure 10 In this configuration, one end of the support hook is bolted to the chain, and the other end extends to the outside of the chain. When a material drop gap is required, a material drop gap is formed between the other end of a support hook at the lower end of the chain of another buffer rack and the lower end of the guide rod of the first upper slide. The width of the material drop gap is greater than the outer diameter of the second-specification longitudinal rib. At this time, the drive sprocket of the other buffer rack stops rotating, and the second-specification longitudinal rib falls into the first lower slide through the material drop gap.

[0073] The second-specification longitudinal rib 7 falls into the first sliding table 31 through the material drop gap. It then falls through the lower side of the first sliding table 31 into the support hook 213 at the lower end of the chain of a buffer rack 21. The drive sprocket 211 of the buffer rack 21 rotates to input the second-specification longitudinal rib 7 through the upper end of the chain into the second sliding table 51. The second-specification longitudinal rib 7 falls through the second sliding table 51 into the rib threading mechanism 4.

[0074] After the first-specification longitudinal bar 6 or the second-specification longitudinal bar 7 falls onto the bar threading mechanism 4, the bar threading mechanism 4 adjusts its position and conveys the first-specification longitudinal bar 6 or the second-specification longitudinal bar 7, so that the first-specification longitudinal bar 6 or the second-specification longitudinal bar 7 is threaded into the steel column cage.

[0075] See Figure 4 As shown, in this embodiment, the first sliding platform and the first upper sliding platform are mounted on the lower part of the side of the frame via a bracket. The first sliding platform is plate-shaped. The first upper sliding platform includes multiple guide rods. The guide rods are inclined. The inclination angle of the guide rods is adapted to the inclination angle of the first sliding platform. The guide rods are arranged along the width direction of the first sliding platform. The multiple guide rods are spaced apart along the length direction of the first sliding platform. The upper surfaces of the multiple guide rods form a slope. The longitudinal reinforcement of the steel column cage is arranged along the length direction of the first sliding platform and rests on the multiple guide rods. Under the self-weight of the longitudinal reinforcement, it slides down along the length direction of the guide rods.

[0076] See Figure 8 As shown in the figure, in this embodiment, the structure of the second upper slide and the second lower slide is similar to that of the first upper slide, and will not be described again here.

[0077] In a preferred embodiment, a fixed baffle 311 is installed on the lower side of the first sliding platform 31. The fixed baffle 311 and the first sliding platform 31 form a notch 310 for the support hook 213 at the lower end of the chain of a buffer rack 21 to pass through.

[0078] In a preferred embodiment, a movable baffle 511 is rotatably mounted on the lower side of the second sliding platform 51. A drive member 512 for driving the movable baffle 511 is hinged between the movable baffle 511 and the top of the frame 1. The lower ends of the multiple guide rods of the second sliding platform are connected to connecting rods. One end of the movable baffle is rotatably sleeved on the connecting rod via a bushing.

[0079] In this embodiment, the drive component 512 is an electro-hydraulic actuator. One end of the electro-hydraulic actuator is hinged to a movable baffle, and the other end is hinged to the top of the frame.

[0080] See Figure 9 As shown, the movable baffle's function is not only to intercept the longitudinal reinforcement or control whether it can fall into the reinforcement threading mechanism via the second sliding platform. By rotating the movable baffle, the drop point of the longitudinal reinforcement can also be adjusted, and the position adjustment of the reinforcement threading mechanism can be coordinated to achieve rapid drop and connection of the longitudinal reinforcement.

[0081] The upper slide (including the first and second upper slides) and the lower slide (including the first and second lower slides) are parallel to each other and inclined at a 25° angle to the horizontal plane. The upper slide is 100mm higher than the lower slide. The upper slide is mainly used for feeding another buffer rack, while the lower feed slide is mainly used for feeding one buffer rack. The supports of the upper slide are arranged at intervals to allow the chain structure of another buffer rack to pass through. Fixed baffles are arranged on the lower side of the first lower slide to block the reinforcing bars. The fixed baffles are spaced apart to allow the chain structure of one buffer rack to pass through.

[0082] Another buffer rack is located to the right of the first buffer rack and is higher than it, allowing the rebar to pass underneath. A third motor and drive shaft are located below the support frame, driving the chain mechanism for lifting. Six sets of chain mechanisms are evenly distributed along the length of the frame to accommodate different rebar lengths. Support hooks are fixed to the chain, evenly spaced at every other chain link, with their openings facing upwards on the feed side. The support hooks have slots; the outer edge of the slot is perpendicular to the bottom edge, and the inner edge forms a 45° angle with the bottom edge. This allows the support hook to hold the rebar when it is in the 45° feed position, and allows the rebar to slide out when the support hook is vertically positioned at the top of the buffer rack, completing the discharge process. A stop bar is located at the bottom of the support frame of the second buffer rack. The stop bar is vertically positioned and maintains a distance from both the upper and lower feed slides of the feed rack, ensuring that the rebar can fall from the upper feed slide to the lower feed slide.

[0083] See Figures 5 to 7 As shown, the guide rail 11 is arranged along the width direction of the frame 1, and a buffer rack 21 is arranged on the side of the frame 1 in the width direction.

[0084] Continue reading Figures 5 to 7 As shown, the reinforcing bar mechanism 4 includes: a support beam 41, a conveying roller 42, a first drive assembly 43, and a second drive assembly 44.

[0085] The support beam 41 is slidably mounted on the guide rail 11. The support beam 41 is arranged along the length of the frame 1. The guide rail is arranged along the length of the support beam.

[0086] There are multiple conveying rollers 42. The conveying rollers 42 are rotatably mounted on the support beam 41. The multiple conveying rollers 42 are arranged along the length of the support beam 41. The circumferential surface of the conveying rollers 42 forms a limiting groove. The limiting grooves of the multiple conveying rollers 42 are connected to form a receiving space for accommodating the first specification longitudinal rib 6 or the second specification longitudinal rib 7.

[0087] The first drive assembly 43 is mounted on the support beam 41. The first drive assembly 43 is used to drive multiple conveyor rollers 42.

[0088] The second drive assembly 44 is mounted on the guide rail 11. The second drive assembly 44 is used to drive the support beam 41.

[0089] In a preferred embodiment, the first drive assembly 43 includes: a rotating shaft 431, a transmission sprocket 432, and a first motor 433.

[0090] The support beam 41 has multiple shaft holes. A rotating shaft 431 is rotatably inserted into each shaft hole. A roller 42 is coaxially mounted on one end of the rotating shaft 431. A drive sprocket 432 is coaxially connected to the other end of each rotating shaft 431. A chain 434 is sleeved on the outside of the multiple drive sprockets 432. A first motor 433 is mounted on the support beam 41. The output end of the first motor 433 is drively connected to a drive sprocket 432.

[0091] In a preferred embodiment, the second drive assembly 44 includes: a gear 441, a rack, and a second motor 443.

[0092] Gear 441 rotatably supports beam 41. Rack is mounted on guide rail 11. Rack meshes with gear 441. Second motor 443 is mounted on support beam 41. Output end of second motor 443 is driven by gear 441.

[0093] Driven by the second drive assembly, the rib-threading mechanism moves along the width of the frame, that is, along the length of the support beam.

[0094] The rebar threading mechanism has traveling rollers underneath, allowing it to move laterally along the base. The threading mechanism has a symmetrical structure and includes a receiving groove (accommodation space) for receiving rebar. The receiving position is directly below the movable baffle, and the far right of the top of the frame is a clearance position, accommodating the receiving requirements of both threading mechanisms. The threading mechanism is equipped with a chain and a roller conveyor to deliver the rebar.

[0095] This invention provides a method for threading longitudinal reinforcement in a reinforced column cage using a longitudinal reinforcement buffer and an automatic reinforcement threading device, comprising the following steps:

[0096] S1. Insert multiple first-specification longitudinal bars 6 into the first upper sliding table 32.

[0097] S2. The drive sprocket 211 of another buffer rack 21 rotates, and multiple first-specification longitudinal ribs 6 fall onto multiple support hooks 213 of another buffer rack 21 via the lower side of the first upper slide 32 to achieve buffering of multiple first-specification longitudinal ribs 6.

[0098] S3, the drive sprocket 211 of another buffer rack 21 rotates to input the first specification longitudinal rib 6 into the second upper slide table 52 via the upper end of the chain.

[0099] S4, the first specification longitudinal bar 6 falls into the bar threading mechanism 4 via the second sliding platform 51;

[0100] S5. After the first-specification longitudinal bar 6 falls onto the bar threading mechanism 4, the bar threading mechanism 4 adjusts its position and conveys the first-specification longitudinal bar 6, so that the first-specification longitudinal bar 6 is threaded into the steel column cage.

[0101] S6. After the second-specification longitudinal rib 7 is put into the first upper slide table 32, the drive sprocket 211 of the other buffer rack 21 is turned off so that the support hook 213 at the lower end of the other buffer rack 21 and the first upper slide table 32 form a material dropping gap.

[0102] S7. The second specification longitudinal rib 7 is dropped into the first sliding table 31 through the material drop gap, and then dropped into the support hook 213 at the lower end of the chain of a buffer rack 21 through the lower side of the first sliding table 31.

[0103] S8. The drive sprocket 211 of a buffer rack 21 rotates to input the second specification longitudinal rib 7 into the second sliding table 51 via the upper end of the chain.

[0104] S9, the second specification longitudinal reinforcement 7 falls into the reinforcement threading mechanism 4 via the second sliding platform 51.

[0105] S10. After the second-specification longitudinal reinforcement 7 falls onto the reinforcement threading mechanism 4, the reinforcement threading mechanism 4 adjusts its position and conveys the second-specification longitudinal reinforcement 7 so that the second-specification longitudinal reinforcement 7 is threaded into the steel column cage.

[0106] During the feeding process, the longitudinal ribs are fed from the first upper slide table. When the support hook at the lower end of the chain of the other buffer rack is in the feeding position (e.g.) Figure 9 As shown), the longitudinal ribs fall along the first feeding slide into another buffer rack, and the other buffer rack completes the feeding.

[0107] When another buffer rack is in a clearance position (e.g.) Figure 10 As shown, a buffer rack is in the feeding position, the longitudinal rib falls from the first upper slide table into the first lower slide table and stops at the fixed baffle, and the buffer rack completes the feeding.

[0108] During the discharge process, when one buffer rack and another buffer rack are in the feeding position, the reinforcing bars at the top of the buffer racks are simultaneously in the discharge position. When the other buffer rack discharges, the reinforcing bars slide down the second upper slide table into the second lower slide table, and then slide down into the movable baffle; when the first buffer rack discharges, the reinforcing bars slide down the second lower slide table into the movable baffle. The movable baffle is connected to the driving component. When the driving component retracts, the movable baffle rises, which can block the longitudinal reinforcing bars; when the driving component extends, the movable baffle falls, and the longitudinal reinforcing bars follow.

[0109] During the material receiving process, one threading mechanism moves laterally to the receiving position, the movable baffle falls down, and the longitudinal rib falls along the movable baffle into the receiving groove of the threading mechanism (the accommodating space formed by the limiting grooves on the wheel surfaces of multiple conveying rollers), and the movable baffle rises up; after the threading mechanism finishes receiving the material, it moves laterally to the rightmost clearance position to wait, and another threading mechanism moves laterally to the receiving position, the movable baffle falls down, and the longitudinal rib falls along the baffle into the receiving groove of the other threading mechanism.

[0110] The longitudinal reinforcement buffer and automatic rebar threading device for the steel column cage of the present invention specifically provides automatic feeding, buffering, and discharging functions for longitudinal reinforcement, enabling buffering of two different specifications of longitudinal reinforcement. The dual buffer mechanism (buffer rack) of the longitudinal reinforcement buffer and automatic rebar threading device of the present invention has the same feed inlet, reducing the number of work stations. The longitudinal reinforcement buffer and automatic rebar threading device of the present invention enables two rebar threading mechanisms to simultaneously pick up and feed materials.

[0111] The longitudinal reinforcement buffer and automatic reinforcement threading device of the steel column cage of the present invention can be arranged as one or three, or it can be an asymmetrical structure.

[0112] The tilt angles of the upper and lower sliding platforms of the longitudinal reinforcement buffer and automatic reinforcement threading device of the steel column cage of the present invention can be other angles.

[0113] The chain spacing and slide table spacing of the longitudinal reinforcement buffer and automatic reinforcement threading device of the steel column cage of the present invention can be varied according to the size of the buffered steel reinforcement.

[0114] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
