Description

Technical Field

[0001] This utility model relates to the field of tape reel technology, and in particular to an adjustable fire hose reel machine. Background Technology

[0002] Fire hose reels are core equipment used in fire rescue for quickly winding up fire hoses. The fire hose reel is secured to the reel by a bracket. The fire hose reel can be driven to rotate by a built-in motor and a reduction gearbox, so that the fire hose secured to the bracket is wound up under the action of rotational force.

[0003] Existing electric fire hose reels use two symmetrical guide frames on the frame to compress and limit the hose during winding. However, the frame structure of these guide frames is relatively simple, and the compression distance during hose winding is not easily adjustable. This affects the smoothness of winding hoses with mud stuck to them, thus hindering the successful winding of fire hoses. Therefore, we propose an adjustable fire hose reel. Utility Model Content

[0004] The main objective of this invention is to provide an adjustable fire hose reel. By setting a lifting mechanism on the base plate of the reel body and installing a pressing mechanism, the bottom limit rod of the lifting mechanism, together with the pressure roller of the pressing mechanism, forms a structure that guides the fire hose during reeling. The pressure roller and the bottom limit rod form a squeezing zone, and during the reeling process, mechanical friction peels off mud from the hose surface, reducing subsequent cleaning costs. The adjustable distance between the pressure roller and the bottom limit rod allows the hose to be adjusted to a slightly swaying position during smooth reeling, which helps to dissipate mud during smooth reeling, effectively solving the problems in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An adjustable fire hose reel includes a reel body and a base plate. The base plate is fixed to the bottom end of the reel body. The reel body also includes a lifting mechanism and a pressing mechanism. The lifting mechanism includes an L-shaped support block, a bottom limit rod, a threaded lifting bolt, a spring, and a ring pressure cover. Four sets of L-shaped support blocks are symmetrically installed on the surface of the base plate on one side of the reel body. A bottom limit rod is installed between opposing L-shaped support blocks. A threaded lifting bolt is welded to the top of each L-shaped support block, and the outer side of the threaded lifting bolt... From bottom to top, a spring and a ring pressure cover are sequentially fitted. A flange nut is screwed onto the threaded lifting bolt above the ring pressure cover. The pressing mechanism includes a U-shaped bracket, a pressure roller, a bearing, and a pressure shaft block. The threaded lifting bolt between the ring pressure cover and the flange nut passes upward through a frame plate hole opened on the surface of the U-shaped bracket. Symmetrical support blocks protrude from the plate surface of the U-shaped bracket near its own frame groove. A pressure roller is installed in the block groove of the support block through a bearing. A pressure shaft block for pressing against the bearing is installed in the block groove on one side of the support block.

[0007] Furthermore, the L-shaped support block has a rotating limiting hole for mounting the bottom limiting rod at the opposing column block, and a support bolt is screwed into the rotating limiting hole at the L-shaped support block, and the smooth bolt body of the support bolt is inserted into the rod holes at both ends of the bottom limiting rod.

[0008] By adopting the above technical solution, the opposing column of the L-shaped support block can be fitted with the bottom limit rod through the rotation limit hole, and then the bolt body of the support bolt can be screwed into the rotation limit hole from the outside of the L-shaped support block, and the smooth bolt body of the support bolt is inserted into the rod hole of the bottom limit rod to provide support for it.

[0009] Furthermore, the L-shaped support block has a recessed limiting groove on the surface of the block plate near the threaded lifting bolt, and a spring is pressed into the recessed limiting groove of the L-shaped support block.

[0010] By adopting the above technical solution, the spring is positioned and locked in the concave groove of the L-shaped support block.

[0011] Furthermore, the upper spring coil of the spring away from the L-shaped support block is covered with a ring pressure cover, and the middle of the ring pressure cover is provided with a cover hole for the threaded lifting bolt to pass through.

[0012] By adopting the above technical solution, the spring can be pressed between the L-shaped support block and the ring pressure cover. With the guidance of the spiral lifting bolt, the spring can be guided to bounce. The spiral lifting bolt can be inserted into the cover hole of the ring pressure cover.

[0013] Furthermore, the bottom of the L-shaped support block is welded with a bottom embedded post, and the bottom embedded post is welded downward into four sets of embedded holes opened on the surface of the substrate.

[0014] By adopting the above technical solution, the four sets of blocks of the L-shaped support are inserted into the holes on the surface of the substrate with bottom embedded posts, which facilitates the positioning and welding installation of the L-shaped support on the surface of the substrate, and allows the bottom limit rod to be installed between each pair of opposing blocks of the L-shaped support.

[0015] Furthermore, the roller body of the pressure roller has symmetrical protrusions at both ends of the roller shaft, and the roller shaft is inserted into the inner ring of the bearing. The outer ring of the bearing is inserted into the slot of the support block, and the slot of the support block has protrusions of guide ribs. The ribs of the guide ribs are inserted into the guide grooves opened on the surface of the pressure roller block, and bolts are screwed between the pressure roller block, the guide ribs and the support block.

[0016] By adopting the above technical solution, after the bearing is clamped on the roller shaft of the pressure roller, the bearing is installed by the pressure roller block pressing it into the groove of the support block. The pressure roller block is guided and clamped at the guide rib of the support block by the guide groove. Then, the roller block, guide rib and support block are locked with bolts to complete the installation of the pressure roller.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This utility model sets a lifting limit mechanism on the base plate of the winding machine body and installs a pressing mechanism. The bottom limit rod at the lifting limit mechanism and the pressure roller of the pressing mechanism can form a structure to guide the fire hose to be wound. The pressure roller and the bottom limit rod form a squeezing area. During the winding process, the mud on the surface of the hose is peeled off by mechanical friction, reducing the subsequent cleaning cost. The adjustable distance between the pressure roller and the bottom limit rod allows the hose to be adjusted to a slightly swinging position when winding smoothly, which helps to swing and dissipate mud when the fire hose is wound smoothly.

[0019] Furthermore, the lifting mechanism uses a spring and a ring pressure cover to support the U-shaped bracket where the pressure roller is located, providing dynamic pressure compensation. This ensures that there is a good elastic adjustable gap between the pressure roller and the bottom limit rod, preventing excessive compression of the fire hose during winding and causing damage to the hose.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figure 1-5 As shown, an adjustable fire hose reel includes a reel body 1 and a base plate 2. The base plate 2 is fixed to the bottom end of the reel body 1. The reel body also includes a lifting mechanism 3 and a pressing mechanism 13. The lifting mechanism 3 includes an L-shaped support block 4, a bottom limit rod 7, a threaded lifting bolt 9, a spring 10, and a ring pressure cover 11. Four sets of L-shaped support blocks 4 are symmetrically installed on the surface of the base plate 2 on one side of the reel body 1. The bottom limit rod 7 is installed between the opposing blocks of the L-shaped support blocks 4. Threaded lifting bolts 9 are welded to the top of the L-shaped support blocks 4, and the outer side of the threaded lifting bolt 9 is sequentially fitted with [missing information - likely related to a specific type of support] from bottom to top. The spring 10 and the ring pressure cover 11 are provided. A flange nut 12 is screwed onto the threaded lifting bolt 9 above the ring pressure cover 11. The pressing mechanism 13 includes a U-shaped bracket 14, a pressure roller 16, a bearing 17, and a pressing block 18. The threaded lifting bolt 9 between the ring pressure cover 11 and the flange nut 12 passes upward through the frame plate hole opened on the surface of the U-shaped bracket 14. The plate surface of the U-shaped bracket 14 near its own frame groove has symmetrically raised support blocks 15. The pressure roller 16 is installed in the block groove of the support block 15 through the bearing 17. A pressing block 18 for pressing against the bearing 17 is installed in the block groove on one side of the support block 15.

[0028] The L-shaped support block 4 has a rotating limit hole 6 for mounting the bottom limit rod 7 at the opposite column block, and a support bolt 8 is screwed into the L-shaped support block 4 and passes through the rotating limit hole 6. The smooth bolt body of the support bolt 8 passes through the rod holes opened at both ends of the bottom limit rod 7.

[0029] By adopting the above technical solution, the opposing column block of the L-shaped support block 4 can be fitted with the bottom limit rod 7 through the rotation limit hole 6, and then the bolt body of the support bolt 8 can be screwed into the rotation limit hole 6 from the outside of the L-shaped support block 4, and the smooth bolt body of the support bolt 8 is fitted into the rod hole of the bottom limit rod 7 to provide support for it.

[0030] Among them, the L-shaped support block 4 has a recessed limiting groove on the surface of the block plate near the threaded lifting bolt 9, and a spring 10 is pressed into the recessed limiting groove of the L-shaped support block 4.

[0031] By adopting the above technical solution, the spring 10 is positioned and locked in the concave groove of the L-shaped support block 4.

[0032] Among them, the upper spring ring of the spring 10 away from the L-shaped support block 4 is covered by a ring pressure cover 11, and the middle of the ring pressure cover 11 is provided with a cover hole for the threaded lifting bolt 9 to pass through.

[0033] By adopting the above technical solution, the spring 10 can be pressed between the L-shaped support block 4 and the ring pressure cover 11. With the guidance of the spiral lifting bolt 9, the spring 10 can be guided to bounce, and the spiral lifting bolt 9 can be inserted into the cover hole of the ring pressure cover 11.

[0034] Among them, the bottom of the L-shaped support block 4 is welded with a bottom embedded post 5, and the bottom embedded post 5 is welded downward into the four sets of embedded holes opened on the surface of the substrate 2.

[0035] By adopting the above technical solution, the four sets of blocks of the L-shaped support block 4 are inserted into the holes on the surface of the substrate 2 by the bottom embedded post 5, which facilitates the positioning and welding installation of the L-shaped support block 4 on the surface of the substrate 2, and allows the bottom limit rod 7 to be installed between each pair of opposing blocks of the L-shaped support block 4.

[0036] The roller 16 has roller shafts symmetrically protruding at both ends of its roller body, and the roller shafts are engaged in the inner ring of the bearing 17. The outer ring of the bearing 17 is engaged in the slot of the rotating block 15, and the slot of the rotating block 15 has a guide rib 19 protruding. The rib of the guide rib 19 is engaged in the guide groove 20 opened on the surface of the pressure shaft block 18, and the pressure shaft block 18, the guide rib 19 and the rotating block 15 are screwed together with bolts.

[0037] By adopting the above technical solution, after the bearing 17 is clamped on the roller shaft of the pressure roller 16, the bearing 17 is pressed into the groove of the support block 15 by the pressure roller block 18 for installation. The pressure roller block 18 is guided and clamped at the guide rib 19 of the support block 15 by the guide groove 20. Then, the roller block 18, the guide rib 19 and the support block 15 are locked with bolts, thereby completing the installation of the pressure roller 16.

[0038] It should be noted that this utility model is an adjustable fire hose reeling machine. A lifting mechanism 3 is provided on the base plate 2 of the reeling machine body 1, and a pressing mechanism 13 is installed in conjunction with it. The L-shaped support block 4 of the lifting mechanism 3 can be fitted with a bottom limit rod 7 through a rotating limit hole 6. Then, the L-shaped support block 4 is positioned and welded into the recessed hole on the surface of the base plate 2 by a bottom embedded post 5. The bolt body of the support bolt 8 can be screwed into the rotating limit hole 6 from the outside of the L-shaped support block 4, and the smooth bolt body of the support bolt 8 is inserted into the rod hole of the bottom limit rod 7 to provide support. Then, the spiral lifting bolt 9 above the L-shaped support block 4 can successively clamp the spring 10 and the ring pressure cover 11. Finally, the U-shaped bracket 14 of the pressing mechanism 13 can be fitted onto the spiral lifting bolt 9 above the ring pressure cover 11 through a bracket plate hole. After the flange nut 12 is tightened and screwed, the bearings 17 are then installed on both ends of the pressure roller 16. The bearings 17 can then be pressed into the slots of the support block 15 by the pressure block 18. The support block 15 is guided by the guide rib 19 and the guide groove 20 of the pressure block 18. Then, the shaft block 18, the guide rib 19, and the support block 15 are tightened with bolts to complete the installation of the pressure roller 16. After the lifting mechanism 3 and the pressing mechanism 13 are assembled, there are two symmetrically arranged guide belt structures on the surface of the base plate 2. After the flange nut 12 is screwed away, the U-shaped bracket 14 can be lifted away from the spiral lifting bolt 9. Then, the middle part of the fire hose is placed between the supports of the winding machine body 1, and the outer sleeve bracket is inserted into the support of the winding machine body 1. The fire hose is limited at the frame, while the sides of the fire hose away from the main body 1 of the winding machine can be placed above the bottom limit bar 7. Then, the U-shaped bracket 14 is re-clamped onto the spiral lifting bolt 9 and the flange nut 12 is tightened. As the flange nut 12 is continuously tightened, the U-shaped bracket 14 presses against the ring pressure cover 11 and obtains elastic support at the spring 10. At the same time, the roller body of the pressure roller 16 moves closer to the bottom limit bar 7, reducing the belt passage distance between the pressure roller 16 and the bottom limit bar 7. Tightening the flange nut 12 causes the U-shaped bracket 14 to move away from the bottom limit bar 7 with the pressure roller 16, thereby adjusting the belt passage distance between the pressure roller 16 and the bottom limit bar 7. Then, the support of the winding machine body 1 can normally wind up the fire hose, and the mud on the surface of the fire hose can be removed during winding. When the hose is being wound up, it is restricted by the pressure roller 16 and the bottom limit rod 7 and then released. After the distance between the pressure roller 16 and the bottom limit rod 7 is increased, it is convenient to quickly wind up the fire hose. At the same time, some mud will also be thrown and contacted between the pressure roller 16 and the bottom limit rod 7 and released. This allows the pressure distance to be adjusted when winding up fire hoses with mud stuck to them, making it convenient for the winding machine to wind up the fire hose. When the hose is about to reach the joint, the winding machine body can be stopped, and then the flange nut 12 can be unscrewed from the threaded lifting bolt 9, thereby removing the U-shaped bracket 14. The remaining hose body can then be manually wound around the wound hose roll. Then, the outer frame rod of the winding machine body 1 can be pulled away from the support of the winding machine body 1, thereby removing the outer frame rod from the wound fire hose roll.
