Technical Field
[0001] This utility model belongs to the field of fire protection facility maintenance technology, specifically relating to a fire protection facility maintenance and rust prevention device. Background Technology
[0002] Fire protection facilities are a general term for the systems and equipment in buildings used for fire prevention, alarm, firefighting, and personnel evacuation. Because fire protection facilities are prone to corrosion due to humidity, salt spray, and other environmental factors when left idle for a long time, they may fail at critical moments. Therefore, it is necessary to maintain fire protection facilities regularly to prevent them from being affected by corrosion.
[0003] Chinese patent document CN220072144U discloses a fire protection facility maintenance and rust prevention device. When maintaining fire protection facilities, the device uses a fixed block to clamp the fire protection facilities and rotate them. Then, a horizontally movable and rotatable cleaning brush comes into contact with the fire protection facilities to complete the rust removal process.
[0004] However, in the existing technology, the rust prevention device has a single operation mode and a limited area of action during the rust removal process. It has the limitation of only being able to deal with rust on the outer surface of fire protection facilities with regular appearance. Therefore, a rust prevention device for fire protection facility maintenance is proposed. Utility Model Content

[0012] Preferably, the loading component includes a lower locking frame movably connected to the side of the main shaft near the worm gear, and an upper locking frame is fixedly connected above the lower locking frame.
[0013] Preferably, the grinding component further includes a bearing seat that is movably connected between the front and rear of the lower and upper clamping frames, respectively. A splined shaft is movably installed inside the bearing seat and passes through it. A limiting pin that passes through the splined shaft is fixedly connected to the splined shaft. A telescopic rod is fixedly connected to the end of the splined shaft away from the second magnetic plate, and a grinding block is fixedly connected to the telescopic end of the telescopic rod.
[0014] Preferably, both the lower and upper fastening frames are rotatably connected to the main shaft and the drive shaft, the worm gear is meshed with the worm wheel, the adjacent splined cylinder is slidably connected to the splined shaft, and both the lower and upper fastening frames are slidably connected to the shaft seat.
[0015] Preferably, the axis of the main shaft is orthogonal to the axis of the transmission shaft, and the bearing seat is a symmetrical double-body structure.

The insertion hole and the insertion rod correspond one-to-one, and the inner diameter of the insertion hole is the same as the outer diameter of the insertion rod.
[0019] The beneficial effects of this utility model are as follows: Based on the fact that the switching component can control the on / off of the power transmission path between the main shaft and the loading component, the setting of the transmission component that can transmit the power of the main shaft in multiple directions allows the two sets of grinding components to rotate independently around the main shaft or the transmission shaft axis to treat the rust on the outer surface of the fire protection facility, and can also rotate around the main shaft axis while rotating around the transmission shaft axis to fit the inner wall of the fire protection facility for rust removal. Thus, this device can meet the needs of various rust prevention work. Attached Figure Description

[0030] The present invention will be further described below with reference to the embodiments and accompanying drawings.
[0031] like Figures 1-5 As shown, a fire protection facility maintenance and rust prevention device includes a drive component 1 that can continuously output power when the device removes rust from the fire protection facility, a rust removal component 2 that can remove rust from different parts of the fire protection facility is provided on one side of the drive component 1, and a switching component 3 that can adjust the operating state of the rust removal component 2 according to the rust removal needs is provided on one side of the drive component 1.
[0032] In this embodiment: the drive assembly 1 includes a power box 101, and a main shaft 102 is movably mounted on one side of the power box 101;
[0033] The main shaft 102 is installed in a power box 101 with built-in motors and other power output components, and handles at the front and rear for easy gripping and lifting by the user. The power output components are connected to the main shaft 102 to provide power for the rotation of the main shaft 102.
[0034] In this embodiment: the rust removal component 2 includes a loading component for mounting its core components, a transmission component for transmitting the rotation of the spindle 102 in multiple directions, and a grinding component that can be connected to the transmission component at different positions to meet different rust removal needs;
[0035] The transmission components include a worm gear 203 fixedly connected to one end of the main shaft 102, a transmission shaft 204 disposed above the worm gear 203, a worm wheel 205 fixedly connected to the outer side of the transmission shaft 204, a splined cylinder 206 fixedly connected to one end of the worm gear 203 and the front and rear ends of the transmission shaft 204 respectively, and a first magnetic suction plate 207 fixedly installed inside the splined cylinder 206. The grinding components include splined shafts 209 respectively disposed in front of and behind the loading components, and a second magnetic suction plate 210 fixedly installed at the ends of the two splined shafts 209 that are close to each other. The loading components include components movably connected to the main shaft 102. 02 A lower retaining frame 201 is located near the worm gear 203. An upper retaining frame 202 is fixedly connected above the lower retaining frame 201. The grinding component also includes a bearing seat 208 that is movably connected between the front and rear of the lower retaining frame 201 and the upper retaining frame 202. A splined shaft 209 is movably installed inside the bearing seat 208 and passes through it. A limiting pin 211 that passes through the splined shaft 209 is fixedly connected to the splined shaft 209. A telescopic rod 212 is fixedly connected to the end of the splined shaft 209 away from the second magnetic plate 210. A grinding block 213 is fixedly connected to the telescopic end of the telescopic rod 212.
[0036] The lower buckle 201 and the upper buckle 202 are rotatably connected to the main shaft 102 and the drive shaft 204. The worm 203 is meshed with the worm wheel 205. The adjacent splined cylinder 206 is slidably connected to the splined shaft 209. The lower buckle 201 and the upper buckle 202 are slidably connected to the bearing seat 208. The axis of the main shaft 102 is orthogonal to the axis of the drive shaft 204. The bearing seat 208 is a symmetrical double-body structure. The lower buckle 201 and the upper buckle 202 have an integrally formed insertion hole on the side of the lower buckle 201 and the upper buckle 202 near the power box 101.
[0037] The rust removal assembly 2 can be rotatably connected to the side of the main shaft 102 away from the power box 101 via the lower fastener 201 and the upper fastener 202. The lower fastener 201 and the upper fastener 202 can also mount the drive shaft 204 and the bearing 208, and accommodate components such as the worm gear 203. The worm gear 203 and worm wheel 205 change the direction of rotation of the main shaft 102 and transmit it to the drive shaft 204. The worm gear 203 and the drive shaft 204 then drive the splined cylinders 206 at different positions to rotate. When the splined shaft 209 is inserted into the splined cylinder 206, the splined cylinder 206 can transmit its own rotation to the splined shaft 209. The first magnetic chuck 207 and the second magnetic chuck 210... The magnetic connection between them prevents the spline shaft 209 from accidentally separating from the spline cylinder 206 after being inserted. The spline shaft 209 is installed through the shaft seat 208, so that it can slide and rotate relative to the shaft seat 208, and can also move circumferentially along the lower buckle 201 and the upper buckle 202 together with the shaft seat 208 after being separated from the spline cylinder 206 by external force. The limiting pin 211, which is longer than the diameter of the spline shaft 209 and located inside the loading part, prevents the spline shaft 209 from sliding excessively relative to the shaft seat 208 and falling off. The grinding block 213, which can remove rust from fire-fighting facilities, is installed through the telescopic rod 212, which is non-rotatable at the telescopic end but tends to move away from the spline shaft 209.
[0038] In this embodiment: the switching component 3 includes an external threaded sleeve 301 fixedly connected to the outer side of the main shaft 102, a dial ring 302 threadedly connected to one side of the external threaded sleeve 301, a slip ring 303 provided on one side of the dial ring 302, a plug rod 304 fixedly connected to one side of the slip ring 303, and a compression spring 305 provided between the external threaded sleeve 301 and the slip ring 303.
[0039] The outer side of the external threaded sleeve 301 is integrally formed with a limiting groove that matches the inner side of the slip ring 303. The slip ring 303 and the compression spring 305 are slidably connected to the external threaded sleeve 301. The insertion hole and the insertion rod 304 correspond one-to-one, and the inner diameter of the insertion hole is the same as the outer diameter of the insertion rod 304.
[0040] The external threaded sleeve 301, which can rotate with the main shaft 102, provides installation positions for the dial ring 302, slip ring 303, and compression spring 305. The compression spring 305 can compress the slip ring 303, causing the slip ring 303, which is not under additional force, to tend to move towards the dial ring 302. The dial ring 302, which rotates relative to the external threaded sleeve 301, can drive the slip ring 303 to move along the length direction of the external threaded sleeve 301, that is, the axial direction of the main shaft 102, thereby changing the distance between the insertion rod 304 and the lower buckle 201 and the upper buckle 202.
[0041] Working principle: When this device is installed for the maintenance and rust prevention of fire protection facilities, it can switch working states to meet different rust removal needs;
[0042] Specifically, the worker can insert one of the spline shafts 209 into the attached [feature / equipment]. Figure 3 After the splined cylinder 206 is separated, the splined shaft 209 can be moved to a position coaxial with the main shaft 102 by moving the bearing seat 208 connected to the splined shaft 209 relative to the lower retaining frame 201 and the upper retaining frame 202. Then, the splined cylinder 206, coaxial with the main shaft 102, is inserted. After the operator holds the handle of the power box 101 and the loading component and runs the power output component in the power box 101, the main shaft 102 can drive the two grinding blocks 213 to rotate through the transmission component, the splined shaft 209, and another splined shaft 209. In this case, the operator can choose one of the two grinding blocks 213 that rotates around the axis of the main shaft 102 and the axis of the transmission shaft 204 respectively to contact the fire-fighting equipment and grind away the rust on the outer surface of the fire-fighting equipment.
[0043] In addition, when it is necessary to clean the rust on the inner wall of the pipe fire protection facility, the lever ring 302 can be rotated to make the slip ring 303 drive the insertion rod 304 to move to the lower buckle 201 and the upper buckle 202. After each insertion rod 304 is inserted into the insertion hole on the lower buckle 201 and the upper buckle 202, the device can be lifted by the power box 101 after the spline shaft 209 is coaxial with the drive shaft 204 and the spline shaft 209 is inserted into its respective adjacent spline cylinder 206. After the extension rod 212 is appropriately compressed, the rust removal component 2 is aligned with the axis of the main shaft 102 on the pipe fire protection facility. The centerline is placed inside. In this case, when the main shaft 102 rotates due to the power output component in the power box 101, it can drive the rust removal component 2 to rotate around its axis. It can also drive the two grinding blocks 213 to rotate around the axis of the transmission shaft 204 through the worm gear 203 and other transmission components. When the telescopic rod 212 tends to move away from the spline shaft 209 at the telescopic end and the grinding blocks 213 are subjected to centrifugal force, the grinding blocks 213, which rotate around the axis of the main shaft 102 and the axis of the transmission shaft 204 respectively, will automatically stick to the inner wall of the pipe fire protection facility to remove rust.
[0044] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
