Description

Technical Field

[0001] This utility model relates to the technical field of rotary kiln bricklaying equipment, specifically a protective platform for laying refractory precast bricks in a rotary kiln. Background Technology

[0002] A rotary kiln is a type of thermal equipment. The lining of a rotary kiln is mainly made of refractory bricks. The refractory bricks in a rotary kiln are divided into several varieties according to different materials and shapes. During the construction of a rotary kiln, different varieties of refractory bricks must be stacked separately in advance. This makes it convenient for the kiln builders to take them out and lay them. At the construction site, workers usually drive a forklift to transport a whole box of refractory bricks to the bricklaying machine platform. Then, four workers unpack the boxes and stack the different varieties of refractory bricks on both sides of the bricklaying machine platform.

This device consists of a central guardrail and two end guardrails, with the end guardrails positioned on either side of the central guardrail. Both the central and end guardrails are connected to the bottom of the bricklaying machine platform. With these safety guardrails installed on the front and rear sides of the bricklaying machine platform, workers are always positioned between the two guardrails while unpacking and stacking refractory bricks and constructing the rotary kiln. The safety factor is greatly improved by the protection of the central and end guardrails, preventing workers from falling off the bricklaying machine platform. However, this patent still has the following problems in practical use:

[0004] To prevent the retractable wing protector from moving back and forth when it is adjusted to the appropriate position, the device uses bolts to fix it at the sleeve. However, when adjusting the retractable wing protector, the operator needs to use multiple sets of bolts to fix it, which greatly reduces the adjustment efficiency of the device and cannot achieve the effect of quickly adjusting and extending the protective structure, causing inconvenience to the operator when using it.

Currently, when using a retractable wing guard device, in order to prevent it from moving back and forth, bolts are used to fix it at the sleeve after it is adjusted to a suitable position. However, when adjusting the retractable wing guard device, the operator needs to use multiple sets of bolts to fix it, which greatly reduces the adjustment efficiency of the device and cannot achieve the effect of quickly adjusting and extending the protective structure, causing inconvenience to the operator when using it.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a protective platform for laying refractory precast bricks in a rotary kiln, comprising a bricklaying machine platform, wherein protective net frames are symmetrically arranged on both sides of the top of the bricklaying machine platform; an adjustment mechanism is provided on one side of the protective net frame, and a connecting component is provided between the protective net frame and the bricklaying machine platform;

[0008] The adjustment mechanism includes a first sliding box installed on one side of the protective net frame, with protective net plates symmetrically arranged at the bottom end of the first sliding box. A second sliding box is installed on one side of the bottom of the protective net frame. A bidirectional screw is rotatably connected inside the first sliding box, and a first movable sleeve is symmetrically threaded to the outer ends of both ends of the bidirectional screw. A fixed rod is installed inside the second sliding box, and a second movable sleeve is symmetrically slidably connected to the outer end of the fixed rod. One end of the first movable sleeve and the second movable sleeve is fixedly connected between the protective net plate. A worm gear is rotatably connected inside the center of the first sliding box, and a worm wheel is installed on the outer end of the center of the bidirectional screw. A circular plate is installed at the bottom end of the worm gear, and insertion holes are opened on the outer side of the circular plate. A support plate is installed on one side of the bottom end of the first sliding box, and an insertion rod is slidably connected inside the support plate. A telescopic spring is sleeved on the outer side of the insertion rod, and one end of the insertion rod is inserted into the insertion hole.

[0009] Preferably, the connecting assembly includes fixed seats symmetrically installed on the top of the bricklaying machine platform, with a strip plate inserted into the top of the fixed seat. Both the fixed seat and the strip plate have slots inside. A fixed box is installed on one side of each fixed seat, and a threaded rod is rotatably connected inside the fixed box. A moving block is threadedly connected to the outside of the threaded rod. A push plate is slidably connected inside one side of the fixed box, and a rotating rod is rotatably connected to one side of the moving block. One end of the rotating rod is rotatably connected to the push plate. A positioning rod is installed on one side of each push plate, and the positioning rod is inserted into the slot.

[0010] Preferably, the inner sides of the first sliding box and the second sliding box are provided with guide grooves, and a connecting plate is installed on one side of the first sliding box and the second sliding box. A guide wheel is rotatably connected inside one side of the connecting plate, and one end of the guide wheel is rolledly connected to the guide groove.

[0011] Preferably, a rotating block is installed at the top of the worm gear.

[0012] Preferably, the movable block is slidably connected between the sliding grooves inside the fixed box.

[0013] Preferably, the top of the strip is fixedly connected to the protective mesh frame.

[0014] Preferably, the worm and the worm wheel are meshed together.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: A protective platform for laying refractory precast bricks in a rotary kiln is described. Specifically, the operator rotates a worm gear, which in turn rotates a worm wheel. This rotation of the worm wheel then rotates a bidirectional screw. The movement of the first movable sleeve moves the protective mesh plate, which in turn moves the second movable sleeve to slide outside the fixed rod. Furthermore, by pulling the insert rod, it slides inside the support plate. At this time, the outer baffle of the insert rod compresses the telescopic spring. Through the restoring property of the telescopic spring, one end of the insert rod can be inserted into the insertion hole, thus achieving rapid fixing of the worm gear and rapid adjustment of the protective mesh plate. This allows the operator to easily adjust the length of the protective structures on both sides of the bricklaying machine platform as needed, thereby further improving... The device's protective effect greatly enhances its flexibility during use. The insertion of the rods and sockets effectively prevents external forces from causing the worm gear to rotate, resulting in more stable operation and improved safety for workers. By rotating multiple sets of threaded rods inside the fixed box, the rotation of the threaded rods causes the moving block to slide within the groove of the fixed box. This movement of the moving block then moves the rotating rod, which in turn causes the push plate to slide within the fixed box. The insertion of multiple positioning rods into the slots allows for quick fixing of the limiting strips, facilitating rapid replacement and maintenance of the protective mesh frame. This significantly improves the device's efficiency and daily maintenance.

[0016] 1. The operator rotates the worm gear, which in turn drives the worm wheel. The rotation of the worm wheel in turn drives the rotation of the double-headed screw. The rotation of the double-headed screw causes the first moving sleeve to move along a convergence and unfolding trajectory. The movement of the first moving sleeve causes the protective mesh plate to move. The movement of the protective mesh plate causes the second moving sleeve to slide outside the fixed rod. When the protective mesh plate moves to the appropriate position, the operator pulls the insertion rod to slide inside the support plate. At this time, the outer baffle of the insertion rod compresses the telescopic spring. By releasing the insertion rod and then using the reset property of the telescopic spring, one end of the insertion rod can be inserted into the insertion hole, thereby achieving the effect of quickly fixing the worm gear. This allows for quick adjustment and fixing of the protective mesh plate, making it convenient for the operator to adjust the length of the protective structure on both sides of the bricklaying machine platform as needed. This further improves the protective effect of the device and greatly enhances the flexibility of the device during use. Furthermore, the insertion between the insertion rod and the insertion hole effectively prevents the worm gear from rotating due to external forces, making the protective device more stable and improving the safety of the operator during use.

[0017] 2. The protective net frame is placed on top of the fixed base by the staff. At this time, the strip plate is inserted into the top of the fixed base. Then, the staff rotates multiple sets of threaded rods inside the fixed box. The rotation of the threaded rods causes the moving block to slide in the groove inside the fixed box. The movement of the moving block causes the rotating rod to move. The rotation of the rotating rod causes the push plate to slide inside the fixed box. At this time, multiple sets of positioning rods are inserted into the slots, thereby achieving the effect of quickly fixing the limiting strip plate. This facilitates the staff to quickly replace and repair the protective net frame, which greatly improves the efficiency of the device and the efficiency of daily maintenance, bringing convenience to the staff during use.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6 The present invention provides a technical solution: a protective platform for laying refractory precast bricks in a rotary kiln, including a bricklaying machine platform 1, with protective net frames 101 symmetrically arranged on both sides of the top of the bricklaying machine platform 1; an adjustment mechanism 2 is provided on one side of the protective net frame 101, and a connecting component 3 is provided between the protective net frame 101 and the bricklaying machine platform 1.

[0027] The adjusting mechanism 2 includes a first sliding box 201 installed on one side of the protective net frame 101, with protective net plates 202 symmetrically arranged at the bottom end of the first sliding box 201. A second sliding box 203 is installed on one side of the bottom of the protective net frame 101. A bidirectional screw 204 is rotatably connected inside the first sliding box 201, and a first movable sleeve 205 is symmetrically threaded to the outer sides of both ends of the bidirectional screw 204. A fixed rod 206 is installed inside the second sliding box 203, and a second movable sleeve 207 is symmetrically slidably connected to the outer side of the fixed rod 206.

A worm gear 208 is rotatably connected inside the center of the first sliding box 201, and a worm wheel 209 is installed on the outer side of the center of the bidirectional screw 204. The worm gear 208 and the worm wheel 209 are meshed together. Furthermore, a circular plate 210 is installed at the bottom end of the worm gear 208, and insertion holes 211 are provided on the outer side of the circular plate 210. A support plate 212 is installed on one side of the bottom end of the first sliding box 201, and an insertion rod 213 is slidably connected inside the support plate 212. A telescopic spring 214 is sleeved on the outer side of the insertion rod 213, and one end of the insertion rod 213 is inserted into the insertion hole 211. This enables the quick adjustment and fixing of the protective net plate 202, and allows the staff to adjust the length of the protective structure on both sides of the bricklaying machine platform 1 as needed, thereby further improving the protective effect of the device and greatly increasing the flexibility of the device during use. The insertion of the insertion rod 213 into the insertion hole 211 effectively prevents the worm gear 208 from rotating due to external forces, making the protective device more stable and improving the safety of the staff during use.

[0028] The inner sides of the first sliding box 201 and the second sliding box 203 are both provided with guide grooves 215, and a connecting plate 216 is installed on one side of the first sliding box 201 and the second sliding box 203. A guide wheel 217 is rotatably connected to one side of the connecting plate 216, and one end of the guide wheel 217 is rolledly connected to the guide groove 215. When the first moving sleeve 205 and the second moving sleeve 207 move, the connecting plate 216 drives multiple sets of guide wheels 217 to move. At this time, the multiple sets of guide wheels 217 roll inside the guide groove 215, which can greatly reduce the resistance encountered by the first moving sleeve 205 and the second moving sleeve 207 when they move, thereby making the movement of the protective net plate 202 more stable. A rotating block 218 is installed at the top of the worm 208. The design of the rotating block 218 makes it easy for the staff to rotate the worm 208.

[0029] The connecting assembly 3 includes a fixed base 301 symmetrically installed on the top of the bricklaying machine platform 1. A strip 302 is inserted into the top of the fixed base 301, and the top of the strip 302 is fixedly connected to the protective net frame 101. Both the fixed base 301 and the strip 302 have slots 303 inside. A fixed box 305 is installed on one side of each fixed base 301, and a threaded rod 306 is rotatably connected inside the fixed box 305. A movable block 307 is threadedly connected to the outer side of the threaded rod 306. The movable block 307 is slidably connected between the sliding grooves inside the fixed box 305. A push plate 308 is slidably connected to one side of the 305, and a rotating rod 309 is rotatably connected to one side of the moving block 307. One end of the rotating rod 309 is rotatably connected to the push plate 308. A positioning rod 310 is installed on one side of the push plate 308, and the positioning rod 310 is inserted into the slot 303. This enables the quick fixing of the limiting strip 302, which facilitates the quick replacement and maintenance of the protective net frame 101 by the staff. This greatly improves the efficiency of the device and the efficiency of daily maintenance, bringing convenience to the staff during use.

[0030] Working principle: Before using this type of protective platform for laying refractory precast bricks in a rotary kiln, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 6As shown, the worker rotates the worm gear 208, which drives the worm wheel 209 to rotate. The rotation of the worm wheel 209 drives the rotation of the bidirectional screw 204. The rotation of the bidirectional screw 204 causes the first movable sleeve 205 to move along a convergence and unfolding trajectory. The movement of the first movable sleeve 205 causes the protective mesh plate 202 to move. The movement of the protective mesh plate 202 causes the second movable sleeve 207 to slide outside the fixed rod 206. When the protective mesh plate 202 moves to the appropriate position, the worker pulls the insertion rod 213 to slide inside the support plate 212. At this time, the outer baffle of the insertion rod 213 compresses the telescopic spring 214. By releasing the insertion rod 213 and then using the restoring property of the telescopic spring 214, one end of the insertion rod 213 can be inserted into the insertion hole 211, thereby achieving the effect of quickly fixing the worm gear 208 and thus achieving the effect of quickly adjusting and fixing the protective mesh plate 202. This allows workers to easily adjust the length of the protective structures on both sides of the bricklaying machine platform 1 as needed, thereby further improving the protective effect of the device and greatly enhancing the flexibility of the device during use. Furthermore, the insertion of the rod 213 into the insertion hole 211 effectively prevents the worm gear 208 from rotating due to external forces, making the protective device more stable and improving the safety of workers. When the first moving sleeve 205 and the second moving sleeve 207 move, the connecting plate 216 drives multiple sets of guide wheels 217 to move. At this time, the multiple sets of guide wheels 217 roll inside the guide groove 215, which greatly reduces the resistance encountered by the first moving sleeve 205 and the second moving sleeve 207 during movement, making the movement of the protective mesh plate 202 more stable. The design of the rotating block 218 makes it easier for workers to rotate the worm gear 208.

[0031] Workers place the protective net frame 101 on top of the fixed base 301. At this time, the strip 302 is inserted into the top of the fixed base 301. Then, workers rotate multiple sets of threaded rods 306 inside the fixed box 305. The rotation of the threaded rods 306 causes the moving block 307 to slide in the groove inside the fixed box 305. The movement of the moving block 307 causes the rotating rod 309 to move. The rotation of the rotating rod 309 causes the push plate 308 to slide inside the fixed box 305. At this time, multiple sets of positioning rods 310 are inserted into the slots 303, thereby achieving the effect of quickly fixing the limiting strip 302. This facilitates the quick replacement and maintenance of the protective net frame 101 by workers, which greatly improves the efficiency of the device and the efficiency of daily maintenance, bringing convenience to workers during use.

[0032] The bricklaying machine platform 1, the protective net frame 101, and the protective net plate 202 are examples of existing technologies. The announcement number CN215484593U discloses a safety guardrail for a rotary kiln bricklaying machine platform. The device used in this design will not be described in detail here.
