Description

Technical Field

[0001] The invention relates to the technical field of furnace cleaning, and in particular to a coking tool and a use method thereof. Background Art

[0002] With the rapid development of new energy, coal-fired power units are responsible for regulating the peak and valley of new energy power. When coal-fired power units are performing deep peak regulation, they need to burn bituminous coal. Due to the low melting point of bituminous coal ash, the risk of coking in the furnace increases. During boiler operation, manual coking is the most effective way to eliminate coke accumulation.

[0003] During the manual coking process, if a large piece of coke falls and hits the coking stick, the hand-held end of the coking stick held by the coking worker will bounce upward and tilt up. The tilted coking stick will cause physical damage to the worker.

[0004] Therefore, it is necessary to improve the coke beating stick to prevent the coke beating stick from being hit by a large piece of coke and then tilting up as a whole, thereby injuring the coke beating personnel during the decoking operation.

[0005] For example, the patent announcement number CN105716098B discloses a "de-coking tool", which includes a hand-held part, a coking rod, and a connecting part connecting the hand-held part and the coking rod, and the connecting part includes an elastic connector and a fixing part. When a large coke block hits the end of the coking rod, the fixing part will break, and the coking rod will move in the direction where the large coke block falls. At this time, since an elastic connector is provided between the hand-held part and the coking rod, the elastic connector will bend with the coking rod, and the hand-held part will not tilt up, thereby ensuring the personal safety of the staff.

[0006] The fixed portion that breaks when bearing a certain weight has limited strength, resulting in the decoking tool being unable to withstand a large load during normal use. Summary of the invention

[0007] In view of the deficiencies in the prior art, the present invention provides a coking tool and a use method and a construction method thereof to solve the above problems.

[0008] The present invention provides the following technical solutions:

[0009] A focusing tool, comprising:

[0010] A fixing rod, wherein a first circular hole and a second circular hole are formed on the fixing rod along a length direction thereof;

[0011] A rotating rod, wherein a third circular hole and a fourth circular hole are formed on the rotating rod along the length direction thereof;

[0012] An easy-to-break pin, wherein the easy-to-break pin is inserted into the first circular hole of the fixed rod and the third circular hole of the rotating rod;

[0013] A rotating pin, the rotating pin being inserted into the second circular hole of the fixed rod and the fourth circular hole of the rotating rod;

[0014] During the coking process, a large coke block falls and hits the rotating rod, causing the breakable pin to break under stress. At the same time, the rotating rod rotates relative to the fixed rod through the rotating pin.

[0015] Preferably, the fixing rod comprises a handheld cylindrical section and a connecting section arranged at one end of the handheld cylindrical section, the connecting section is in a U-shaped structure, and the first circular hole and the second circular hole are provided on the connecting section of the U-shaped structure.

[0016] Preferably, a handle is provided at the other end of the handheld cylindrical section, and a non-slip rubber sleeve is provided on the outside of the handle.

[0017] Preferably, a hexagonal prism is provided at the other end of the hand-held cylindrical section for focusing; an impact tool is also included, and the hexagonal prism is adapted to the connecting hole of the impact tool.

[0018] Preferably, the impact tool is a pneumatic pick or an electric pick.

[0019] Preferably, the rotating rod includes a defocusing cylindrical section and a rotating disk and a tip arranged at both ends of the defocusing cylindrical section, the third circular hole and the fourth circular hole are opened on the rotating disk, and the rotating disk is inserted into the connecting section of the U-shaped structure.

[0020] Preferably, the handheld cylindrical section includes a fixed section, a movable section and a rotary connector connecting the fixed section and the movable section, and a counterweight is provided on the rotary connector.

[0021] Preferably, the side wall protrusion of the fixed rod is provided with a first friction block, and the side wall protrusion of the rotating rod is provided with a second friction block, and the first friction block and the second friction block correspond to each other and overlap and abut against each other.

[0022] Preferably, the first friction block and the second friction block are in a double diamond overlapping structure.

[0023] A method for using a focusing tool comprises the following steps:

[0024] Hold the fixing rod with your hand and make sure the fixing rod is outside the boiler coke hole;

[0025] The rotating rod is located inside the boiler;

[0026] When a large coke block falls off, it hits the rotating rod downward, the breakable pin breaks due to the shear force, the rotating rod rotates downward around the rotating pin, and the fixed rod and the rotating rod are misaligned, thereby preventing the fixed rod from rebounding upward.

[0027] The present invention has the following beneficial technical effects:

[0028] When a large coke block hits the rotating rod in the boiler, the breakable pin breaks, and the breakage of the breakable pin serves as a breakthrough point. The rotating rod rotates toward the direction where the large coke block falls, and the fixed rod does not tilt, thereby ensuring the personal safety of the staff.

[0029] The two friction blocks are set in a double diamond overlapping structure, with a large contact surface in the center area and a smaller contact surface at both ends. When the friction surfaces of the rotating drill and the bracket completely overlap, the friction force is large and stability can be maintained. When rotation is required, the contact surface at the two ends is small, the friction force is small, and it can be quickly disengaged. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] Embodiment 1:

[0044] A focusing tool, such as Figure 1 , 2 , 5, and 6: It includes an impact tool 1, a fixed rod 2, and a rotating rod.

[0045] The impact tool 1 can be a pneumatic pick or an electric pick.

[0046] The fixing rod 2 can be made of aluminum alloy to reduce weight; the fixing rod 2 includes a handheld cylindrical section 8, a hexagonal prism 7 and a connecting section 9, one end of the handheld cylindrical section 8 is a hexagonal prism 7 for connecting with the impact tool 1, and the other end of the handheld cylindrical section 8 is a U-shaped connecting section 9; the U-shaped connecting section 9 is arranged with two pairs of first circular holes 10 and second circular holes 11, and the arrangement direction of the first circular holes 10 and the second circular holes 11 is consistent with the length direction of the fixing rod 2. The U-shaped connecting section 9 has two pairs of protruding, double diamond overlapping structure first friction blocks 12 arranged in pairs on the opposite inner walls, and the first friction block 12 is relatively located between the first circular hole 10 and the second circular hole 11.

[0047] The connecting hole of the impact tool 1 is adapted to the hexagonal prism 7 of the hand-held cylindrical section 8 .

[0048] The rotating rod 3 can be made of aluminum alloy to reduce weight; the rotating rod 3 includes a scorching cylindrical section 14, a rotating disk 13 and a tip 15, the rotating disk 13 and the tip 15 are respectively arranged at both ends of the scorching cylindrical section 14, and the rotating disk 13 is arranged with two pairs of third circular holes 17 and fourth circular holes 18 in pairs; and the arrangement direction of the third circular holes 17 and the fourth circular holes 18 is consistent with the length direction of the rotating rod 3. The second friction blocks 19 with raised, double diamond overlapping structures are arranged in pairs on the opposite side walls of the rotating disk 13; and the second friction blocks 19 are relatively located between the third circular holes 17 and the fourth circular holes 18; the end of the rotating disk 13 away from the scorching cylindrical section 14 is a semicircular arc structure.

[0049] The first circular hole 10 on the U-shaped connecting section 9 and the third circular hole 17 on the rotating disk 13 cooperate with each other and are connected by an easy-to-break pin 4, which can be supported by rubber; the second circular hole 11 on the U-shaped connecting section 9 and the fourth circular hole 18 on the rotating disk 13 cooperate with each other and are connected by a rotating pin 5, which can be a metal pin whose strength is much greater than that of the easy-to-break pin 4. The above arrangement enables the fixed rod 2 and the rotating rod 3 to be collinear.

[0050] The first friction blocks 12 on the two opposite inner side walls of the U-shaped connecting section 9 and the second friction blocks 19 on the two opposite outer side walls of the rotating disk 13 correspond to each other one by one; the rotating disk 13 is relatively inserted into the interior of the U-shaped connecting section 9, so that the second friction blocks 19 are inserted into the space between the two groups of first friction blocks 12, and the first friction blocks 12 and the second friction blocks 19 overlap;

[0051] The first friction block 12 and the second friction block 19 are both configured as a double diamond overlapping structure, with a large contact surface in the center area and a small contact surface at both ends. When the friction surfaces of the rotating rod 3 and the fixed rod 2 completely overlap, the friction force is large and stability can be maintained. When the breakable pin 4 breaks and causes the rotating rod 3 to rotate relative to the fixed rod 2, the contact surface at the two end areas is small, the friction force is small, and the rod can be quickly disengaged.

[0052] Embodiment 2: Contains all the contents of Embodiment 1, such as Figure 3-6 As shown, the difference is that a handle 6 is used to replace the impact tool 1 for manual coking. The outer wall of the handle 6 is provided with an anti-skid rubber sleeve.

[0053] Directions:

[0054] Step 1, insert the hexagonal prism 7 of the fixed rod 2 into the connecting hole of the pneumatic pick or electric pick to complete the connection between the fixed rod 2 and the pneumatic pick or electric pick; insert the rotating disk 13 of the rotating rod 3 into the connecting section 9 of the U-shaped structure of the fixed rod 2, the first circular hole 10 on the connecting section 9 is coaxial with the third circular hole 17 on the rotating disk 13, and is connected and fixed with the easy-to-break pin 4; the second circular hole 11 on the connecting section 9 is coaxial with the fourth circular hole 18 on the rotating disk 13, and is connected and fixed with the rotating pin 5; complete the connection between the fixed rod 2 and the rotating rod 3, so that the fixed rod 2 and the rotating rod 3 are collinear;

[0055] Step 2. During the coke poking operation, the coke poking worker holds a pneumatic pick or an electric pick, and holds the handle 6 when using manual power; the fixed rod 2 is located outside the coke poking hole of the boiler / furnace, and the rotating rod 3 is located inside the boiler / furnace; when a large coke block falls off, the coke block hits the rotating rod 3 downward, and the breakable pin 4 breaks due to the shear force, and the rotating rod 3 rotates downward around the rotating pin 5, and the fixed rod 2 and the rotating rod 3 are misaligned, thereby preventing the fixed rod 2 from rebounding upward and physically striking the coke poking worker; the fixed rod 2 is tightly extended into the boiler / furnace, and when a large coke block falls off, it does not hit the rotating rod 3 but directly hits the fixed rod 2, which will not play a protective role.

[0056] Embodiment 3: Contains all the contents of Embodiment 1 / 2, except that Figure 7 As shown, the handheld cylindrical section 8 includes a fixed section 81, a movable section 82, and a rotary connector 83 connecting the fixed section 81 and the movable section 82, and a counterweight 84 is provided at a non-center portion of the rotary connector 83 (the portion fixedly connected to the movable section 82);

[0057] The fixed section 81 is fixedly connected to the hexagonal prism 7 / handle 6, and the movable section 82 is fixedly connected to the connecting section 9.

[0058] During use, the coke-poking worker clamps the fixed section 81, while the movable section 82 rotates coaxially relative to the fixed section 81 through the rotating connector 83. The coke-poking worker controls the fixed section 81 to rotate a certain angle. Under the action of the counterweight 84, the connecting section 9 maintains a specific angle relative to the ground, so that the U-shaped connecting section 9 remains hollow above and below, thereby ensuring that the fixed rod 2 can rotate downward smoothly when a large coke block falls off and hits the rotating rod 3.

[0059] The above arrangement can avoid improper operation by the coke-poking worker (for example, the connecting section 9 of the U-shaped structure is hollowed out on the left and right), which may result in failure to play a protective role.

[0060] Embodiment 4: includes all the contents of Embodiment 3, except that Figure 8 As shown:

[0061] The rotary connector 83 includes a first connecting portion 831 and a second connecting portion 832 that are coaxially connected and rotated. The first connecting portion 831 is fixedly connected to the fixed section 81, and the second connecting portion 832 is fixedly connected to the movable section 82. A plurality of hemispherical slots are provided at the edges of the first connecting portion 831 and the second connecting portion 832 that are close to each other. The plurality of hemispherical slots are evenly distributed around the first connecting portion 831 / the second connecting portion 832 in the circumferential direction. The two hemispherical slots of the first connecting portion 831 and the second connecting portion 832 cooperate to form a slot 833 of a spherical structure.

[0062] The weight object 84 includes a connecting rope 841 and a plurality of weight beads 842 arranged at equal intervals on the connecting rope 841. The outer surface of the weight beads 842 is wrapped with an elastic rubber layer. One end of the connecting rope 841 is fixedly connected to the second connecting portion 832.

[0063] In the first use state, the connecting rope 841 and the plurality of weight beads 842 thereon are suspended and hang freely.

[0064] In the second usage state, the counterweight beads 842 are embedded into the corresponding slots 833, and the first connecting part 831 and the second connecting part 832 are relatively fixed through the counterweight beads 842. At this time, several counterweight beads 842 are evenly distributed circumferentially around the first connecting part 831 / the second connecting part 832 to achieve uniform weight distribution.

[0065] The tip 15 can be designed to be a non-rotating structure, such as a flat shape, a square knife shape, a crescent shape, etc. In this case, if the tip 15 cannot be used to burn from various angles in the first use state;

[0066] In the second use state, the rotary connector 83 is relatively fixed so that the tip 15 can be used for focusing from various angles. At this time, if the rotating rod 3 is subjected to a certain impact force, the counterweight bead 842 can be driven to disengage from the slot 833.

[0067] The above-mentioned embodiments only express the specific implementation of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
