Description

Technical Field

[0001] The invention relates to the technical field of fire fighting machinery, in particular to a fire fighting sprinkler head disassembly and assembly device. Background Art

[0002] At present, the loading and unloading of fire sprinkler heads on the market still adopts the method of manual direct loading and unloading. This traditional manual loading and unloading is not only prone to errors in installation accuracy, but also creates safety hazards of high-altitude operations during the loading and unloading process. During manual loading and unloading, for higher positions, racks or ladders are usually used. The loading and unloading personnel stand on the racks or ladders to load and unload the fire sprinkler heads. The overall movement is inconvenient. After loading and unloading one, people need to come down and move to another location for loading and unloading. It is sometimes unsafe for loading and unloading personnel to stand on the racks or ladders, and they are prone to stepping on air or falling down, causing safety accidents.

[0014] The present invention has outstanding substantial features and significant progress compared with the prior art. Specifically, universal wheels with brake mechanisms are installed around the lower surface of the lower base plate of the present invention, which are convenient for movement. The height of the upper storage plate and the mechanical claw can be adjusted according to the installation height of the spray head. First, when the two first servo reduction motors and the two second servo reduction motors are not started, the height of the upper base plate can be adjusted by four multi-stage hydraulic telescopic columns, so that the lifting rod, the lower storage plate, the upper storage plate and the mechanical claw can be lifted and adjusted as a whole. Then, the two first servo reduction motors are started again, and the power shafts of the two first servo reduction motors drive the two first gears to rotate. The two first gears are respectively engaged with the left rack structure and the right rack structure on the outer periphery of the lifting rod, thereby driving the lifting rod to move up and down, so that the operating height of the mechanical claw is adapted to the installation position of the spray head. The two first servo reduction motors stop, and the mechanical claw is an existing mature device, which can perform a series of operations such as rotation, lifting, and clamping. The specific structure and working principle are no longer repeated.When it is necessary to install the sprinkler head, first, it is necessary to push the sprinkler head into each second circular hole in the upper storage plate. At this time, the second stage rod of the first tamping rod is completely pulled out and locked, so that the first tamping rod and the second tamping rod are at the same height. Then, the sprinkler head is placed in each first circular hole, so that each sprinkler head is placed on each first shipping base and each second shipping base, and the two second servo reduction motors are started. The two second servo reduction motors drive the two second gears to rotate, and the two second gears are respectively engaged with the left and right rack structures on the outer periphery of the lifting rod. In this way, the lower storage plate is moved upward as a whole until the upper surface of the first round cover fits the lower surface of the second disc body. In this process, each first tamping rod The tops of the rods and the second tamping rods are in pressing contact with the lower surface of the second disc body. As the lower storage disc continues to move upward, the lower ends of the first tamping rods and the second tamping rods will respectively apply downward pressure to the first mounting ring and the second mounting ring, so that the first mounting ring and the second mounting ring both move downward relative to the first disc body. The first mounting ring lifts up the first consignment bases through the first levers, and the second mounting ring lifts up the second consignment bases through the second levers. The first compression springs are squeezed, and the first consignment bases and the second consignment bases will lift up the sprinkler heads from the first circular holes, and at the same time, the sprinkler heads enter the second circular holes accordingly. During this process, the lower end of each vertical pillar is in sliding contact with the outer circumferential side surface in the annular groove. The outer circumferential side surface in the annular groove is a conical surface that is thick at the top and thin at the bottom. In this way, as the lower storage disk moves upward, the outer circumferential side surface in the annular groove will exert an inward thrust on each vertical pillar. Each vertical pillar will slide toward the center of the second disk body along the radial direction of the second disk body under the guidance of each guide long hole and each T-shaped guide long groove. Each vertical pillar drives each pull rod to move radially inward, and each pull plate pulls each steel wire rope inward, so that the two locking pieces at the corresponding second circular hole position are pulled apart, and each second compression spring is squeezed to ensure that the upper part of the sprinkler head can pass through the two upwards. The two second servo reduction motors rotate in the opposite direction to move the lower storage disk downward as a whole so that the staff can re-place the spray heads in the first circular holes. During this process, the second compression springs rebound, so that the adjacent sides of the corresponding two clamping pieces are docked, the lower part of the spray head is clamped, and the spray head is dragged (the spray head is generally a structure with a large top and a small bottom, with a step in the middle, and the two clamping pieces can be lifted at the step). At the same time, the first compression springs also rebound, so that the first consignment bases and the second consignment bases move downward relative to the first disc body, and then the mechanical claws can clamp the spray heads out of the second circular holes one by one and install them on the corresponding mounting seats.

[0015] When the old shower head needs to be removed, the old shower head is unscrewed from its mounting seat by the mechanical claw, and then the old shower head is placed in the second circular hole of the upper storage plate. The old shower head can be stuck in the third circular hole between the two locking pieces at the position of the second circular hole. The mechanical claw then takes out the new shower head clamp placed in the other second circular holes and directly installs it on the mounting seat. In this way, the following situation will occur: the old shower heads are stored in several intervals of the second circular holes, while the rest of the second circular holes are empty. In this way, it is necessary to push new shower heads into some of the empty second circular holes of the upper storage plate through the lower storage plate, and at the same time receive the old shower heads stored in some of the second circular holes of the upper storage plate. Therefore, first, lock the upper end of the second stage rod of the first tamping rod. The bolts are loosened, so that the first-stage rod of the first tamping rod moves downward and shrinks in the second-stage rod, so that the height of the first tamping rod is lower than that of the second tamping rod, and then the two second servo reduction motors are started. The two second servo reduction motors drive the two second gears to rotate, and the two second gears are respectively meshed with the left-side rack structure and the right-side rack structure on the outer periphery of the lifting rod. In this way, the lower storage plate is moved upward as a whole until the upper surface of the first round cover fits the lower surface of the second disc body. During this process, only the top of each second tamping rod is in pressure contact with the lower surface of the second disc body. As the lower storage plate continues to move upward, the lower end of each second tamping rod will exert downward pressure on the second mounting ring, so that the second mounting ring moves downward relative to the first disc body, the first mounting ring does not move, and the second mounting ring passes through each The second lever lifts each second carrying base upward, and the first compression spring at the outer end of each second lever is squeezed, so that each second carrying base will lift each new sprinkler head upward from the corresponding first circular hole, and at the same time, each new sprinkler head will enter the corresponding second circular hole above. In this process, the lower end of each vertical pillar slides in contact with the outer circumferential side surface in the annular groove, and the outer circumferential side surface in the annular groove is a conical surface that is thick at the top and thin at the bottom. In this way, as the lower storage disk moves upward, the outer circumferential side surface in the annular groove will apply an inward thrust to each vertical pillar, and each vertical pillar will slide toward the center of the second disk body along the radial direction of the second disk body under the guidance of each guide long hole and each T-shaped guide long groove, and each vertical pillar drives each The pull rods move radially inward, and each pull plate pulls each steel wire rope inward, so that the two blocking pieces at the corresponding second circular hole positions are pulled apart, and each second compression spring is squeezed to ensure that the upper part of the new sprinkler head can pass upward through the middle of the corresponding two blocking pieces. At the same time, each old sprinkler head passes downward through the middle of the corresponding two blocking pieces and falls into the corresponding first circular holes. After that, the two second servo reduction motors rotate in the opposite direction to move the lower storage disk downward as a whole. In this process, each second compression spring rebounds, so that the adjacent sides of the corresponding two blocking pieces are docked, the lower part of the new sprinkler head is stuck, and the new sprinkler head is dragged. At the same time, the first compression springs at the outer ends of each second lever also rebound, so that each second shipping base moves downward relative to the first disc body.The pushing, receiving and removing of the new and old sprinkler heads are completed simultaneously.

[0016] The invention has scientific design, reasonable structure, convenient movement, manpower saving, high efficiency and can realize automatic loading and unloading of fire sprinkler heads. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Universal wheels 4 with brake mechanisms are installed around the lower surface of the lower base plate 2 of the present invention, which are convenient for movement. The height of the upper storage plate and the mechanical claw 1 can be adjusted according to the installation height of the sprinkler head. First, when the two first servo reduction motors 7 and the two second servo reduction motors 15 are not started, the height of the upper base plate 3 can be adjusted by four multi-stage hydraulic telescopic columns 5, so that the lifting rod 6, the lower storage plate, the upper storage plate and the mechanical claw 1 can be lifted and lowered as a whole. Then, the two first servo reduction motors 7 are started, and the power shafts of the two first servo reduction motors 7 drive the two first gears 10 to rotate. The two first gears 10 are respectively engaged with the left and right rack structures on the periphery of the lifting rod 6, thereby driving the lifting rod 6 to move upward. The mechanical claw 1 is an existing mature device, which can perform a series of operations such as rotation, lifting, and clamping. The specific structure and working principle are not repeated here. When the spray head needs to be installed, the spray head needs to be pushed into each second circular hole 32 in the upper storage disk. At this time, the second stage rod 22-2 of the first tamping rod 22 is completely pulled out and locked, so that the first tamping rod 22 and the second tamping rod 23 are at the same height, and then the spray head is placed in each first circular hole 13, so that each spray head is placed on each first consignment base 20 and each second consignment base 21, and the two second servo reduction motors 15 are started. The high-speed motor 15 drives the two second gears 16 to rotate, and the two second gears 16 are respectively meshed with the left and right rack structures on the outer periphery of the lifting rod 6, so that the lower storage plate is moved upward as a whole until the upper surface of the first round cover 12 is in contact with the lower surface of the second disc body 30. During this process, the tops of the first tamping rods 22 and the second tamping rods 23 are pressed against the lower surface of the second disc body 30. As the lower storage plate continues to move upward, the lower ends of the first tamping rods 22 and the second tamping rods 23 will respectively apply downward pressure to the first mounting ring 18 and the second mounting ring 19, so that the first mounting ring 18 and the second mounting ring 19 are moved downward relative to the first disc body 11. The first mounting ring 18 is pressed against the first disc body 11 by the first tamping rods 22 and the second tamping rods 23. The first levers 24 lift up each first shipping base 20, and the second mounting rings 19 lift up each second shipping base 21 through each second lever 25. Each first compression spring 27 is squeezed, and each first shipping base 20 and each second shipping base 21 will lift up each spray head from each first circular hole 13, and at the same time, each spray head enters into each second circular hole 32 accordingly. In this process, the lower end of each vertical support 36 is in sliding contact with the outer circumferential side surface in the annular groove 17. The outer circumferential side surface in the annular groove 17 is a conical surface that is thick at the top and thin at the bottom. In this way, as the lower storage plate moves upward, the outer circumferential side surface in the annular groove 17 will apply an inward thrust to each vertical support 36.Each vertical support 36 slides toward the center of the second disk body 30 along the radial direction of the second disk body 30 under the guidance of each guide long hole 37 and each T-shaped guide long groove 9, and each vertical support 36 drives each pull rod 39 to move radially inward, and each pull plate 40 pulls each wire rope 46 inward, so that the two blocking pieces 41 at the position of the corresponding second circular hole 32 are pulled apart, and each second compression spring 45 is squeezed to ensure that the upper part of the sprinkler head can pass upward through the middle of the two blocking pieces 41. After that, the two second servo reduction motors 15 rotate in the opposite direction to move the lower storage disk downward as a whole so that the staff can The spray heads are re-placed in the first circular holes 13. During this process, the second compression springs 45 rebound, so that the adjacent sides of the corresponding two clamping pieces 41 are connected, the lower part of the spray head is clamped, and the spray head is dragged (the spray head is generally a structure with a large top and a small bottom, with a step in the middle, and the two clamping pieces 41 can be lifted at the step). At the same time, the first compression springs 27 also rebound, so that the first consignment bases 20 and the second consignment bases 21 move downward relative to the first disc body 11, and then the mechanical claw 1 can clamp the spray heads out of the second circular holes 32 one by one and install them on the corresponding mounting seats;

[0038] When the old shower head needs to be removed, the old shower head is unscrewed from its mounting seat by the mechanical claw 1, and then the old shower head is placed in the second circular hole 32 of the upper storage plate. The old shower head can be stuck in the third circular hole 42 between the two locking pieces 41 at the position of the second circular hole 32. The mechanical claw 1 then takes out the new shower head placed in the other second circular holes 32 and directly installs it on the mounting seat. In this way, the following situation will occur: the old shower heads are stored in several intervals of the second circular holes 32, while the rest of the second circular holes 32 are empty. In this case, it is necessary to push new shower heads into some of the empty second circular holes 32 of the upper storage plate through the lower storage plate, and at the same time receive the old shower heads stored in some of the second circular holes 32 of the upper storage plate. Then, firstly, loosen the locking bolt 28 at the upper end of the second stage rod 22-2 of the first tamping rod 22, so that the first stage rod 22-1 of the first tamping rod 22 moves downward and shrinks in the second stage rod 22-2, so that the height of the first tamping rod 22 is lower than the second tamping rod 23, and then start the two second servo reduction motors 15, and the two second servo reduction motors 15 drive the two second gears 16 to rotate, and the two second gears 16 are respectively engaged with the left and right rack structures on the outer periphery of the lifting rod 6, so that the lower storage plate is moved upward as a whole until the upper surface of the first round cover 12 and the lower surface of the second disc body 30 are in contact with each other. In this process, only the top of each second tamping rod 23 is in contact with the lower surface of the second disc body 30. As the lower storage plate continues to move upward, each The lower end of the second tamping rod 23 will apply downward pressure to the second mounting ring 19, so that the second mounting ring 19 moves downward relative to the first disc body 11, the first mounting ring 18 does not move, and the second mounting ring 19 lifts each second shipping base 21 upward through each second lever 25. The first compression spring 27 at the outer end of each second lever 25 is squeezed, and each second shipping base 21 will lift each new spray head upward from the corresponding first circular hole 13. At the same time, each new spray head enters the corresponding second circular hole 32 above. In this process, the lower end of each vertical support 36 slides in contact with the outer circumferential side surface of the annular groove 17. The outer circumferential side surface of the annular groove 17 is a conical surface that is thick at the top and thin at the bottom. In this way, as the lower storage plate moves upward, As the second circular hole 32 is moved, the outer circumferential side surface in the annular groove 17 applies an inward thrust to each vertical pillar 36, and each vertical pillar 36 slides toward the center of the second circular hole 30 along the radial direction of the second circular hole 30 under the guidance of each guide long hole 37 and each T-shaped guide long groove 9, and each vertical pillar 36 drives each pull rod 39 to move radially inward, and each pull plate 40 pulls each wire rope 46 inward, so that the two blocking pieces 41 at the position of the corresponding second circular hole 32 are pulled apart, and each second compression spring 45 is squeezed to ensure that the upper part of the new sprinkler head can pass upward through the middle of the corresponding two blocking pieces 41. At the same time, each old sprinkler head passes downward through the middle of the corresponding two blocking pieces 41 and falls into the corresponding first circular hole 13. After that,The two second servo reduction motors 15 rotate in the opposite direction, so that the lower storage plate moves downward as a whole. During this process, each second compression spring 45 rebounds, so that the adjacent sides of the corresponding two blocking pieces 41 are connected, the lower part of the new shower head is clamped, and the new shower head is dragged. At the same time, the first compression spring 27 at the outer end of each second lever 25 also rebounds, so that each second shipping base 21 moves downward relative to the first disc body 11, and the pushing and receiving and removing of the new and old shower heads are completed synchronously.

[0039] The lower base plate 2 is provided with a hydraulic system for controlling the multi-stage hydraulic telescopic column 5 and a battery (conventional technology, not shown in the figure) for powering the mechanical claw 1, two first servo reduction motors 7 and two second servo reduction motors 15.
