Description

Technical Field

[0001] This utility model belongs to the field of transportation technology and relates to a vertical transportation device, particularly a vertical transportation device for building materials inside a dry quenching coke oven. Background Technology

[0002] During the construction or overhaul of dry quenching coke ovens, a large amount of refractory bricks, castables and other masonry materials need to be transported from the ground to the working platform on the top of the oven, which is tens of meters high. Traditional vertical transportation mainly relies on construction elevators or tower cranes.

[0003] After the construction elevator transports the masonry materials to the top of the furnace, manual replacement of the lifting equipment is required for secondary lifting, which is prone to material blockage and has low efficiency. Tower cranes, on the other hand, cannot achieve precise docking and have a low degree of automation. Therefore, developing a vertical transportation device specifically designed for this scenario, capable of rapid, precise, and automated lifting, is of great significance for ensuring construction safety, improving masonry efficiency, and shortening the construction period. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a vertical transportation device for masonry materials inside a dry quenching coke oven. The technical problem this utility model aims to solve is: how to achieve rapid, accurate, and automated vertical transportation of masonry materials inside a dry quenching coke oven, thereby ensuring construction safety and improving masonry efficiency.

[0005] The objective of this utility model can be achieved through the following technical solutions: A vertical transport device for building materials inside a dry quenching coke oven includes a lifting plate, a frame fixed to the top of a vertical guide rail, and an annular guide rail fixed to the top of the dry quenching coke oven. Four sliders are symmetrically fixed to both ends of the lifting plate about its vertical center line, and the sliders slide inside the vertical guide rail. A winch is fixed to the top of the frame, and one end of a wire rope inside the winch passes through the frame and is fixedly fitted with a hook. A fixing frame is fixed to the top of the lifting plate, and a hook plate is fixed to the top of the fixing frame. The hook plate and the hook are movably engaged. A base plate is fixed to the top of the lifting plate via a pushing assembly. A material box is fixedly placed on the top of the base plate, and a top plate is fixed to the top of the material box, with a locking block fixed to the top of the top plate. A traveling trolley slides inside the annular guide rail, and the bottom end of the traveling trolley is fixedly connected to the locking block via a self-locking lifting device.

[0006] The working principle of this utility model is as follows: After placing the masonry materials inside the material box, the material box is placed on top of the bottom plate. The winch winds up the wire rope, causing the wire rope to lift the hook plate and move it upward, thus moving the fixed frame upward. This, in turn, causes the lifting plate and slider to rise horizontally along the vertical guide rail. The horizontal rise of the lifting plate causes the bottom plate and material box to rise to the top of the dry quenching coke oven. At this time, the pushing component pushes the bottom plate and material box to a suitable position below the moving trajectory of the traveling trolley. The traveling trolley then moves along the inner ring guide rail to above the material box. During the movement of the traveling trolley, the self-locking lifting device engages with the locking block. The movement of the traveling trolley then causes the locking block to move, causing the locking block to move the top plate and material box along the ring guide rail to various masonry points on the top of the dry quenching coke oven. The workers can then remove the material box and begin masonry work. This vertical transportation device for masonry materials in the dry quenching coke oven achieves rapid, accurate, and automated vertical transportation of masonry materials, thereby ensuring construction safety and improving masonry efficiency.

[0007] Four rollers are evenly fixed on both sides of the slider, and the rollers are tumblingly connected to both sides of the vertical guide rail.

[0008] By adopting the above structure, the roller reduces the friction between the slider and the vertical guide rail, thus increasing the service life of the slider.

[0009] The lifting plate is hollow inside, with two connecting holes at the top and two rotating holes at the bottom. The pushing assembly includes two rotary motors and two gear plates. Both rotary motors are fixed to the outer wall of the bottom of the lifting plate. The output end of the rotary motor rotates through the rotating holes to the inner wall of the top of the lifting plate. A gear is fixed on the outer cylindrical surface of the output end of the rotary motor, and the gear meshes with the gear plate. A connecting block is fixed on the top of the gear plate, and the connecting block slides inside the connecting hole. The connecting block is fixed to the bottom of the base plate.

[0010] With the above structure, the rotating motor drives the gear to rotate, which in turn pushes the gear forward. The forward movement of the gear drives the connecting block to move forward along the inside of the connecting hole, which in turn moves the base plate and the material box to a suitable position below the moving trajectory of the traveling trolley. This makes it easy for the traveling trolley to move the material box without the need for manual secondary lifting.

[0011] Limiting holes are provided on both sides of the lifting plate, and limiting plates are fixed on the opposite sides of the two toothed plates, with the limiting plates sliding inside the limiting holes.

[0012] The above structure, through the use of limiting plates and limiting holes, further limits the position of the base plate, preventing excessive force on the connecting block during the movement of the toothed plate, thereby increasing the movement stability of the toothed plate.

[0013] A fixing plate is fixed at the top of the base plate, and two rubber plates are fixed on the inner wall of the fixing plate. The cross-section of the fixing plate and the rubber plates is U-shaped. Two permanent magnets are fixed on the inner wall of the fixing plate on the side away from the opening end. The permanent magnets are magnetically connected to the material box.

[0014] Using the above structure, the material box is pushed into the fixed plate along the rubber plate and fixed by permanent magnet magnetic attraction, thereby preventing the material box from shaking during the rising and moving process and increasing the stability of the material box.

[0015] The self-locking hoist includes a connecting plate fixed to the bottom of the traveling trolley, and a connecting rope is fixed to the bottom of the connecting plate. A rectangular plate is fixed to the other end of the connecting rope, and the rectangular plate has a U-shaped cross-section. The rectangular plate is movably engaged with the locking block.

[0016] Using the above structure, the moving trolley drives the connecting plate and connecting rope to move, which in turn moves the rectangular plate to engage with the locking block, thus completing the self-locking. There is no need for manual hooking. The connecting rope connects the connecting plate and the rectangular plate, allowing the rectangular plate to be displaced, which makes it easier for workers to separate the rectangular plate and the locking block later, and thus facilitates the removal of the material box.

[0017] A connecting frame is fixed at the top of the opening of the rectangular plate, and a baffle is rotatably connected inside the connecting frame. A limiting block is fixed at the bottom of the opening of the rectangular plate, and the side of the limiting block near the baffle is engaged and fixed with the baffle.

[0018] With the above structure, during the movement of the rectangular plate, the baffle impacts the locking block, causing the baffle to rotate along the connecting frame and allowing the locking block to enter the interior of the rectangular plate. When the traveling trolley stops, the locking block impacts the baffle under the action of inertia and force reaction. At this time, the baffle rotates in the opposite direction and is blocked by the limiting block, which limits the movement of the locking block and prevents the locking block from detaching from the rectangular plate, thereby preventing the material box from falling off and causing damage to the masonry material inside the material box.

[0019] Multiple extension plates are uniformly fixed at the bottom end of the annular guide rail, and a foot is fixed at the bottom end of the long arm of the extension plate. The foot is fixed to the top of the dry quenching coke oven.

[0020] Using the above structure, the position of the circular guide rail is fixed by the cooperation of the base and the extension plate.

[0021] The extension plate has an L-shaped cross-section. The height of the long arm of the extension plate is higher than the fixed position of the material box, and the length of the short arm of the extension plate is greater than the length of the material box.

[0022] The above structure facilitates the movement of the circular guide rail without obstructing the material box.

[0023] Compared with existing technologies, this vertical conveying device for building materials inside a dry quenching coke oven has the following advantages: This invention, by setting a movable base plate inside a vertical lifting device and placing a material box equipped with a locking block on the top of the base plate, allows the vertical lifting device to lift the material box to the top of the dry quenching coke oven. After the vertical lifting device lifts the material box to the top of the dry quenching coke oven, a pushing component pushes the base plate and the material box to a suitable position below the moving trajectory of the traveling trolley. Finally, the traveling trolley moves the material box along the circular guide rail to various masonry points on the top of the dry quenching coke oven. This vertical transportation device for masonry materials in the dry quenching coke oven achieves rapid, precise, and automated vertical transportation of masonry materials, thereby ensuring construction safety and improving masonry efficiency.

[0024] This invention utilizes a rotary motor to drive a gear, which in turn moves the gear forward. This forward movement of the gear causes the connecting block to move along the inside of the connecting hole, thereby moving the base plate and the material box to a suitable position below the trajectory of the traveling trolley. This facilitates the movement of the material box by the traveling trolley, eliminating the need for manual secondary lifting.

[0025] This invention prevents the material box from shaking during lifting and movement by pushing the material box along the rubber plate into the fixed plate and fixing it with a permanent magnet, thereby increasing the stability of the material box.

[0026] In this invention, during the movement of the rectangular plate, the baffle impacts the locking block, causing the baffle to rotate along the connecting frame and allowing the locking block to enter the interior of the rectangular plate. When the traveling trolley stops, the locking block impacts the baffle under the action of inertia and force reaction. At this time, the baffle rotates in the opposite direction and is blocked by the limiting block, which limits the movement of the locking block and prevents it from detaching from the rectangular plate, thereby preventing the material box from falling off and causing damage to the masonry material inside the material box.

[0035] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0036] like Figures 1-7 As shown, the vertical transport device for masonry materials inside this dry quenching coke oven includes a lifting plate 103, a frame 101 fixed to the top of a vertical guide rail frame 102, and an annular guide rail 401 fixed to the top of the dry quenching coke oven. Four sliders 108 are symmetrically fixed to both ends of the lifting plate 103 about its vertical centerline, and the sliders 108 slide inside the guide rail of the vertical guide rail frame 102. A winch 106 is fixed to the top of the frame 101. One end of a steel wire rope inside the winch 106 passes through the frame 101 and is fixed with a hook 107. A fixed frame 104 is fixedly provided at the top of the plate 103, and a hook plate 105 is fixedly provided at the top of the fixed frame 104. The hook plate 105 is movably engaged with the hook 107. A base plate 201 is fixedly provided at the top of the lifting plate 103 through a pushing component. A material box 301 is fixedly placed at the top of the base plate 201. A top plate 302 is fixedly provided at the top of the material box 301, and a locking block 303 is fixedly provided at the top of the top plate 302. A traveling trolley 404 slides inside the annular guide rail 401, and the bottom end of the traveling trolley 404 is fixedly connected to the locking block 303 through a self-locking hanger.

[0037] After placing the masonry materials inside the material bin 301, the material bin 301 is placed on top of the base plate 201. The winch 106 then winds up the wire rope, causing the hook 107 to lift the hook plate 105 upwards, which in turn moves the fixed frame 104 upwards. This, in turn, causes the lifting plate 103 and the slider 108 to rise horizontally along the interior of the vertical guide rail frame 102. The horizontal rise of the lifting plate 103 then lifts the base plate 201 and the material bin 301 to the top of the dry quenching coke oven. At this point, the pushing assembly pushes the base plate 201 and the material bin 301 to a suitable position below the moving trajectory of the traveling trolley 404. The traveling trolley 404 then... 4. Move along the inside of the annular guide rail 401 to above the material box 301. During the movement of the traveling trolley 404, the self-locking lifting device is engaged inside the locking block 303. Then, the movement of the traveling trolley 404 drives the locking block 303 to move, so that the locking block 303 drives the top plate 302 and the material box 301 along the annular guide rail 401 to various masonry points on the top of the dry quenching coke oven. The workers can then remove the material box 301 and carry out the masonry work. This vertical transportation device for masonry materials in the dry quenching coke oven achieves rapid, accurate, and automated vertical transportation of masonry materials in the dry quenching coke oven, thereby ensuring construction safety and improving masonry efficiency.

[0038] Four rollers 109 are evenly fixed on both sides of the slider 108, and the rollers 109 are tumblingly connected to both sides of the vertical guide rail frame 102.

[0039] In this embodiment, the roller 109 reduces the friction between the slider 108 and the vertical guide rail 102, thereby increasing the service life of the slider 108.

[0040] The lifting plate 103 is hollow inside, and two connecting holes 110 are opened at the top of the lifting plate 103, and two rotating holes 130 are opened at the bottom of the lifting plate 103. The pushing component includes two rotary motors 205 and two toothed plates 203. The two rotary motors 205 are fixed to the outer wall of the bottom end of the lifting plate 103. The output end of the rotary motor 205 rotates on the inner wall of the top end of the lifting plate 103 through the rotating holes 130. A gear 206 is fixed on the outer cylindrical surface of the output end of the rotary motor 205, and the gear 206 meshes with the toothed plate 203. A connecting block 202 is fixed at the top of the toothed plate 203, and the connecting block 202 slides inside the connecting hole 110. The connecting block 202 is fixed to the bottom end of the base plate 201.

[0041] In this embodiment, the rotary motor 205 drives the gear 206 to rotate, thereby pushing the gear 206 forward. The forward movement of the gear 206 causes the connecting block 202 to move forward along the inside of the connecting hole 110, thereby moving the base plate 201 and the material box 301 to a suitable position below the moving trajectory of the traveling trolley 404, so that the traveling trolley 404 can move the material box 301 without the need for secondary manual lifting.

[0042] Limiting holes 120 are provided on both sides of the lifting plate 103, and limiting plates 204 are fixed on the opposite sides of the two toothed plates 203. The limiting plates 204 slide inside the limiting holes 120.

[0043] In this embodiment, the position of the base plate 201 is further limited by the cooperation of the limiting plate 204 and the limiting hole 120, so as to prevent the connecting block 202 from being subjected to excessive force during the movement of the toothed plate 203, thereby increasing the movement stability of the toothed plate 203.

[0044] A fixing plate 207 is fixed at the top of the base plate 201, and two rubber plates 208 are fixed on the inner wall of the fixing plate 207. The cross-section of the fixing plate 207 and the rubber plates 208 are both U-shaped. Two permanent magnets 209 are fixed on the inner wall of the side of the fixing plate 207 away from the opening end. The permanent magnets 209 are magnetically connected to the material box 301.

[0045] In this embodiment, the material box 301 is pushed into the fixed plate 207 along the rubber plate 208 and fixed by the permanent magnet 209, thereby preventing the material box 301 from shaking during the rising and moving process and increasing the fixed stability of the material box 301.

[0046] The self-locking lifting device includes a connecting plate 405 fixed to the bottom of the traveling trolley 404, and a connecting rope 406 is fixed to the bottom of the connecting plate 405. A rectangular plate 407 is fixed to the other end of the connecting rope 406, and the cross-section of the rectangular plate 407 is U-shaped. The rectangular plate 407 is movably engaged with the locking block 303.

[0047] In this embodiment, the moving trolley 404 drives the connecting plate 405 and the connecting rope 406 to move, thereby moving the rectangular plate 407 to engage with the locking block 303, thus completing self-locking. No manual hooking is required. The connecting rope 406 connects the connecting plate 405 and the rectangular plate 407, allowing the rectangular plate 407 to be displaced, which facilitates the separation of the rectangular plate 407 and the locking block 303 by the staff, and makes it easier to remove the material box 301.

[0048] A connecting frame 408 is fixedly provided at the top of the opening of the rectangular plate 407, and a baffle 409 is rotatably connected inside the connecting frame 408. A limiting block 410 is fixedly provided at the bottom of the opening of the rectangular plate 407, and the side of the limiting block 410 near the baffle 409 is engaged and fixed with the baffle 409.

[0049] In this embodiment, during the movement of the rectangular plate 407, the baffle 409 impacts the locking block 303, causing the baffle 409 to rotate along the connecting frame 408, and the locking block 303 to enter the interior of the rectangular plate 407. When the traveling trolley 404 stops, the locking block 303 impacts the baffle 409 under the action of inertia and force reaction. At this time, the baffle 409 rotates in the opposite direction and is blocked by the limiting block 410, so that the baffle 409 limits the movement position of the locking block 303, preventing the locking block 303 from detaching from the rectangular plate 407, thereby preventing the material box 301 from falling off and causing damage to the masonry material inside the material box 301.

[0050] Multiple extension plates 402 are evenly fixed at the bottom end of the annular guide rail 401, and a foot 403 is fixed at the bottom end of the long arm of the extension plate 402. The foot 403 is fixed to the top of the dry quenching coke oven.

[0051] In this embodiment, the position of the annular guide rail 401 is fixed by the cooperation of the base 403 and the extension plate 402.

[0052] The extension plate 402 has an L-shaped cross-section. The height of the long arm of the extension plate 402 is higher than the fixed position of the material box 301, and the length of the short arm of the extension plate 402 is greater than the length of the material box 301.

[0053] In this embodiment, the circular guide rail 401 is convenient to move without obstructing the material box 301.

[0054] The working principle of this utility model: First, the masonry materials are placed inside the material bin 301. Then, the material bin 301 is placed on top of the base plate 201. The winch 106 then winds up the wire rope, causing the hook 107 to lift the hook plate 105 upwards. This causes the fixed frame 104 to move upwards, which in turn causes the lifting plate 103 and the slider 108 to rise horizontally along the guide rail of the vertical guide rail frame 102. The horizontal rise of the lifting plate 103 causes the base plate 201 and the material bin 301 to rise to the top of the dry quenching coke oven. At this time, the rotary motor 205 drives the gear 206 to rotate, which in turn pushes the gear 206 forward. The forward movement of the gear 206 causes the connecting block 202 to move forward along the connecting hole 110, which in turn moves the base plate 201 and the material bin 301 forwards. Move to a suitable position below the trajectory of the traveling trolley 404. At this time, the traveling trolley 404 moves along the inside of the annular guide rail 401 to above the material box 301. The movement of the traveling trolley 404 drives the connecting plate 405 and the connecting rope 406 to move, which in turn drives the rectangular plate 407 to move and engage with the locking block 303. Then, the locking block 303 drives the top plate 302 and the material box 301 along the annular guide rail 401 to various masonry points on the top of the dry quenching coke oven. Finally, the workers at each masonry point on the top of the dry quenching coke oven move the baffle 409 to a position that does not obstruct the locking block 303, and then move the material box 301 to separate the locking block 303 from the rectangular plate 407, so that the material box 301 can be removed for masonry work.

[0055] In summary, by setting a movable base plate 201 inside the vertical lifting device and placing the material box 301 equipped with a snap-fit ​​block 303 on top of the base plate 201, after the vertical lifting device lifts the material box 301 to the top of the dry quenching coke oven, the pushing component pushes the base plate 201 and the material box 301 to a suitable position below the moving trajectory of the traveling trolley 404. Finally, the traveling trolley 404 moves the material box 301 along the annular guide rail 401 to various masonry points on the top of the dry quenching coke oven, enabling the vertical transportation device for masonry materials inside the dry quenching coke oven to achieve rapid, accurate, and automated vertical transportation of masonry materials inside the dry quenching coke oven, thereby ensuring construction safety and improving masonry efficiency.
