Description

Technical Field

[0001] The present invention relates to the technical field of hoisting equipment, and in particular to a hoisting device and operating equipment. Background Art

[0002] During the construction of water conservancy and hydropower projects, it is necessary to install hydro-generator sets. During the installation process, it is necessary to use a crane to lift and hoist these devices to the top of the equipment installation site, and then lower the equipment to the installation and connection position for accurate installation. When the crane lifts and lowers the equipment, due to the heavy weight of the equipment, the steel cable needs to withstand a large tension. During the process of the drum winding and unwinding the steel cable, greater pressure and friction will be generated between the steel cable and the drum. The greater pressure and friction will generate more heat on the drum. If the heat cannot be dissipated in time, the pressure and friction of the steel cable will easily cause deformation or damage to the drum, reducing the service life of the drum and increasing the construction cost.

[0003] In the prior art, Chinese patent document CN116675130A discloses a winch device with a heat dissipation function and a rotary drilling rig having the same, which mainly includes: a drum, a reducer located inside the drum and close to one end of the drum, and a coupling connected to the other end of the drum. The reducer, drum and coupling form a cavity. The cavity is filled with coolant, and the other end of the coupling is connected to a rotary joint, and a cooling circulation device is externally connected through the rotary joint. The cooling circulation device includes a heat exchanger, an oil pipe and a cooling pump. The rotary joint, cooling pump and heat exchanger are respectively connected by oil pipes. During operation, the coolant enters the cooling circulation system through the rotary joint, and the cooled liquid returns to the cavity through the oil pipe. Its feature is that when the rotary drilling rig is working, the heat inside the winch can be dissipated in a timely and effective manner, thereby ensuring the normal working life of the reducer and the rotary drilling rig; its disadvantage is that heat is dissipated by pouring hydraulic oil into the drum, which not only has a more complicated structure, but also because the drum is rotating, the part where the rotating seal is formed is prone to seal failure, which will cause hydraulic oil, so it is necessary to replace the sealing ring regularly, which is more inconvenient to use.

[0004] In addition, Chinese patent document CN213085311U discloses a winch reducer that is easy to dissipate heat, including a drum body, a first end cover and a second end cover are respectively provided at both ends of the drum body, a planetary reducer body is fixed on the second end cover, a cooling fan is provided at the end of the sun gear shaft of the planetary reducer body, a plurality of rear cooling holes are provided on the first end cover, and a plurality of front cooling holes are provided on the second end cover. Its characteristics are: heat is dissipated by the cooling fan, no leakage of hydraulic oil is involved, and there is no need to replace the sealing ring regularly, which is more convenient to use; its disadvantages are: the rotation of the cooling fan requires another motor drive, and the structure is relatively complicated.

[0009] The adjusting device is a handle, which is fixedly mounted on the screw rod. A limiting hole is provided on the handle, and a locking hole is provided on the end cover. After the locking bolt passes through the limiting hole on the handle, it is fixedly connected to the locking hole.

[0010] A heat dissipation mechanism is installed on the inner wall of the hollow structure of the drum. The heat dissipation mechanism includes a plurality of graphite rings, which are installed inside the drum.

[0011] Each of the graphite rings is composed of two half rings. Two T-shaped bars are axially arranged on the inner wall of the hollow structure of the reel, and the two half rings of the graphite ring are respectively clamped on both sides of the T-shaped bar.

[0012] Each half ring of the graphite ring is fixedly mounted with a first arc-shaped strip at one end and an arc-shaped groove at the other end. A clamping groove is provided on the inner wall of one side of the winding drum. The first arc-shaped strip of one half ring is clamped in the clamping groove, and the first arc-shaped strips of the remaining half rings are clamped in the arc-shaped groove of the previous half ring in sequence.

[0016] An operating device adopts the hoisting device, and the drum of the hoisting device is used for winding and installing a steel cable.

[0017] Compared with the prior art, the present invention has the following technical effects: 1. The present invention installs a cooling mechanism within the hollow structure of the drum. When the drum rotates, it drives the fan blades to rotate. The fan blades generate wind through the fan blades, removing the heat from the drum. The rotation of the fan blades does not require additional drive equipment, and the structure is simpler.

[0018] 2. The present invention uses arc-shaped graphite rings and fan blades. Since the graphite rings have good thermal conductivity, the heat generated by the large pressure and friction between the reel and the steel cable can be quickly transferred to the graphite rings. The heat on the graphite rings is quickly blown out by the fan blades, so that the graphite rings and the external air can quickly exchange heat, so that the graphite rings are quickly cooled, and the heat on the reel is further conducted and discharged, making it difficult for the reel to be overheated and deformed or damaged, thereby improving the service life of the reel.

[0019] 3. The present invention divides the graphite ring into two half rings. When a single graphite half ring is damaged, there is no need to replace the entire graphite ring, thereby reducing costs. The first clamping hole, the second clamping hole and the clamping column are provided. The first clamping hole and the second clamping hole are clamped by the clamping column to fix the graphite half ring, so that multiple graphite half rings are fixed separately. The graphite half rings are not prone to sliding. At the same time, when a single graphite ring is damaged, the other graphite rings inside will not shake or be damaged, thereby improving the stability of the device.

[0020] 4. The present invention sets an adjustment device to drive the axial movement of the internal threaded sleeve, thereby driving the rotating block and the fan blades to rotate, and driving the fan blades to rotate a certain angle. When the equipment is pulled up and dropped, the reel and the rotating tube rotate forward and reverse. By adjusting the angle of the fan blades, the fan blades can blow out the heat on the graphite ring on the inner wall of the rotating tube from the air outlet, so as to facilitate the utilization of the hot air.

[0021] 5. The present invention blows the heat on the graphite ring out from the fixed tube through the fan blades, and the hot air is discharged from the exhaust pipe through the pipeline, so as to dry the moisture on the steel cable and prevent the steel cable from rusting. It can also prevent the moisture on the steel cable from dripping onto the reel and causing rust damage to the reel, thereby improving the service life of the equipment.

DETAILED DESCRIPTION

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] It should be noted that references in the specification to "this embodiment," "embodiment," "exemplary embodiments," "some embodiments," etc. indicate that the described embodiments may include specific features, structures, or characteristics, but not every embodiment necessarily includes such specific features, structures, or characteristics. In addition, when specific features, structures, or characteristics are described in conjunction with an embodiment, it should be within the knowledge of those skilled in the relevant art to implement such features, structures, or characteristics in conjunction with other embodiments (whether or not explicitly described).

[0027] Example 1: See also Figure 2-9, a winch device includes a support frame 102 and a drum 105, the drum 105 is rotatably mounted on the support frame 102 through the protruding shafts at both ends, the drum 105 is transmission-connected to the reduction motor 103, the reduction motor 103 is used to drive the drum 105 to rotate on the support frame 102, a cooling mechanism 3 is installed in the hollow structure of the drum 105, the drum 105 and the protruding shafts at both ends have a through hollow structure, the cooling mechanism 3 includes a fan blade, the fan blade includes a center seat 303 and fan blades 305, and a plurality of fan blades 305 are evenly distributed in an annular manner on the center seat 303, an end cover 301 is installed at the end of the protruding shaft at one end of the drum 105, the center seat 303 is connected to the end cover 301 through a fixing strip 302, an air outlet is provided on the end cover 301, and a filter plate 209 is installed at the other end of the drum 105, and the filter holes on the filter plate 209 form an air inlet.

[0028] By installing the cooling mechanism 3 in the hollow structure of the drum 105, when the drum 105 rotates, the fan blades are driven to rotate, and the rotation of the fan blades generates wind through the fan blades 305 to take away the heat inside the drum 105. The rotation of the fan blades does not require additional driving equipment, and the structure is simpler.

[0029] During use, air enters from the filter holes on the filter plate 209 and is then discharged from the air outlet of the end cover 301, thereby taking away the heat in the hollow structure of the reel 105. The filter holes on the filter plate 209 mainly prevent larger debris from entering the reel 105.

[0030] Example 2: Based on Example 1, see Figure 5 、 7 , 8, 9, the center seat 303 is a hollow shell structure, a plurality of rotating blocks 304 are rotatably mounted on the center seat 303, each fan blade 305 is fixedly connected to the rotating block 304, the rotating block 304 passes through the side wall of the center seat 303, and a fixed rod 306 is fixedly mounted on one end of the rotating block 304 located inside the center seat 303, and the fixed rod 306 is eccentrically connected to the rotating block 304, and a round sleeve 307 is rotatably mounted on the fixed rod 306, and the round sleeve 307 is fixedly connected to one end of the connecting rod 308, and the other end of each connecting rod 308 is fixedly connected to the connecting rod 308. It is pivotally hinged with the internal threaded sleeve 309, and the internal threaded sleeve 309 is screwed together with one end of the screw 310, and the other end of the screw 310 is movably extended out of the end cover 301. The end of the screw 310 extending out of the end cover 301 is connected to the adjustment device, and the screw 310 is driven forward and reversed by the adjustment device to adjust the angle of the fan blade 305, so that when the reel 105 rotates forward or reverse, the fan blade 305 can still blow air to dissipate heat, and keep air entering from the filter holes on the filter plate 209, and then discharged from the air outlet of the end cover 301.

[0031] In this embodiment, three rotating blocks 304 are rotatably mounted on the center seat 303. Figure 8 , there are three mounting holes evenly distributed in an annular pattern on the center seat 303, the rotating block 304 is cylindrical, and the rotating block 304 is connected to the mounting holes on the center seat 303 through a bearing. Figure 9 A fixing rod 306 is fixedly installed at one end of the rotating block 304 located inside the center seat 303. The fixing rod 306 is eccentrically connected to the rotating block 304. When the fixing rod 306 is pushed, the rotating block 304 can be driven to rotate, thereby reversing the fan blades 305 on the rotating block 304.

[0032] Furthermore, fixed rod 306 is hingedly connected to internally threaded sleeve 309 via connecting rod 308. Internally threaded sleeve 309 is mounted on screw rod 310. Internally threaded sleeve 309 cannot rotate due to the restriction of connecting rod 308. When screw rod 310 is rotated, internally threaded sleeve 309 moves axially on screw rod 310, thereby pushing and pulling fixed rod 306 via connecting rod 308, causing fan blades 305 on rotating block 304 to reverse direction. When screw rod 310 is rotated, screw rod 310 only rotates. The cooperation between screw rod 310 and internally threaded sleeve 309 has two extreme positions, which just cause fan blades 305 on rotating block 304 to reverse direction.

[0033] In this embodiment, see Figure 8 The adjustment device is a handle 311, which is fixedly mounted on the screw 310. The handle 311 is provided with a limit hole, and the end cover 301 is provided with a locking hole 313. The locking bolt 312 is inserted into the limit hole on the handle 311 and then fixedly connected with the locking hole 313. By rotating the handle 311, the screw 310 is rotated. By rotating the handle 311, the direction of the fan blade 305 is adjusted, and the structure is simple.

[0034] When large-scale equipment is hoisting objects via a winch, the cable is repeatedly wound between the fixed and movable pulleys, resulting in a longer run time and a faster rotation speed for the drum 105. During operation, the angle of the fan blades 305 can be adjusted by turning the handle 311 in advance, depending on whether the drum 105 needs to rotate forward or reverse. The handle 311 is then secured to the end cap 301 via the locking bolt 312. The locking bolt 312 can be a screw, and the locking hole 313 is a threaded hole.

[0035] Of course, the adjustment device can also be an electromagnetic push rod or an electric push rod installed on the end cover 301. The telescopic end of the electromagnetic push rod or the electric push rod is fixedly connected to the screw 310. The electromagnetic push rod or the electric push rod pushes the screw 310, and the screw 310 pushes the internal threaded sleeve 309, thereby driving the fan blades 305 to rotate in the adjustment direction. Since the end cover 301 rotates with the reel 105, the electromagnetic push rod or the electric push rod also rotates with the end cover 301. Therefore, during implementation, it is necessary to power the electromagnetic push rod or the electric push rod through an electric slip ring, which is installed on the central axis of the end cover 301. For example, the electric slip ring is installed at the center of the tail of the electromagnetic push rod or the electric push rod. One end of the electric slip ring is connected to the power supply, and the other end is electrically connected to the electromagnetic push rod or the electric push rod, so that the fan blades 305 can be automatically adjusted.

[0036] Example 3: On the basis of Example 1 or Example 2, see Figure 4 、 5 The inner wall of the hollow structure of the reel 105 is equipped with a heat dissipation mechanism 2, which includes multiple graphite rings 204. The graphite rings 204 are installed inside the reel 105. The graphite rings have high thermal conductivity and can quickly disperse heat to the surrounding environment, thereby achieving a heat dissipation effect.

[0037] In this embodiment, the graphite ring 204 absorbs heat from the inner wall of the drum 105 and releases the heat into the cavity inside the graphite ring 204 .

[0038] See also Figure 4 Each graphite ring 204 is composed of two half rings. Two T-shaped bars 203 are axially provided on the inner wall of the hollow structure of the reel 105. The two half rings of the graphite ring 204 are slidably mounted on both sides of the T-shaped bar 203.

[0039] Furthermore, each half of the graphite ring 204 has a first curved strip 205 fixedly mounted on one end and an arcuate groove 206 defined at the other end. A slot 208 is defined on the inner wall of one side of the winding drum 105. The first curved strip 205 of one half of the ring is clipped into the slot 208, and the first curved strips 205 of the remaining half of the ring are sequentially clipped into the arcuate groove 206 of the preceding half of the ring. A boss 210 is provided on the side of the filter plate 209 that faces the graphite ring 204. A second curved strip 211 is provided on the end face of the boss 210. The second curved strip 211 is clipped into the arcuate groove 206 of the adjacent half of the ring. This structure allows for the splicing and installation of the graphite rings 204.

[0040] Further, see Figure 4, each half ring of the graphite ring 204 is provided with a limit plate 207 at one end close to each other, the limit plate 207 is clamped on the side of the T-shaped bar 203, the limit plate 207 is provided with a second clamping hole 219, and the T-shaped bar 203 is provided with a first clamping hole 218 at the position corresponding to the second clamping hole 219. Figure 6 , on the boss 210 of the filter plate 209, a fixed shell 212 is fixedly installed on the upper side of the corresponding T-shaped bar 203, and the filter plate 209 is provided with two through slots 213 at the position corresponding to the fixed shell 212. A movable plate 214 is slidably installed in the two fixed shells 212, and one end of the movable plate 214 extends to the other side of the filter plate 209 through the through slot 213, and a baffle 215 is installed thereafter. The baffle 215 is connected to the outer side of the filter plate 209 by bolts, and one side of the movable plate 214 is elastically and slidably connected to the inner wall of the fixed shell 212 by multiple elastic members 217. A plurality of clamping columns 216 are fixed on the other side of the movable plate 214, and the position of each clamping column 216 corresponds to the position of the first clamping hole 218. When the clamping column 216 slides out of the fixed shell 212 for a distance, the clamping column 216 correspondingly penetrates the first clamping hole 218 and the second clamping hole 219 to limit each half ring of the graphite ring 204.

[0041] Specifically, in this embodiment, the elastic member 217 is preferably a spring sheet, one end of which is fixedly connected to the fixed shell 212 , and the other end of which elastically supports the movable plate 214 .

[0042] The provided clamping column 216 is clamped with the first clamping hole 218 and the second clamping hole 219, so that the arc-shaped graphite half rings can be fixed one by one. When a single graphite half ring is damaged, the other graphite half rings are not easily shaken and damaged.

[0043] It should be noted that in this embodiment, the post 216 has a hemispherical structure, and the first and second holes 218 and 219 respectively mate with the hemispherical post 216. When installing or removing the movable plate 214, the post 216 can be moved into the interior of the fixed housing 212 by pulling the baffle 215. The post 216 can pass through the first hole 218, but does not need to pass completely through the second hole 219. The post 216 abuts and mates with the second hole 219 via the elastic member 217, thereby retaining the graphite half rings in position. Example 4: Since the steel cable on the hoisting device is exposed to the outside, it is easy to adhere to moisture, causing the steel cable to rust. Based on Example 1 or Example 2 or Example 3, see Figure 4 、 5 The hoisting device also includes a dust removal mechanism 4, which is used to blow dry the moisture on the steel cable.

[0044] Specifically, the dust removal mechanism 4 includes an exhaust pipe 405, which is provided with multiple exhaust ports. The exhaust pipe 405 is connected to a pipe 402. The air outlet on the end cover 301 extends to the center of the end cover 301 through a fixed pipe 314. A rotary joint is installed at one end of the fixed pipe 314 located in the center of the end cover 301, and the pipe 402 is connected to the rotary joint.

[0045] The fan blades 305 discharge the heat on the graphite ring 204 from the exhaust pipe 405 through the pipe 402. During use, since the blown wind has a certain amount of heat, it can quickly dry the moisture on the steel cable, and the water on the steel cable is not easy to drip onto the reel 105, causing the reel 105 to rust, thereby improving the service life of the equipment. In this embodiment, the exhaust pipe 405 is annular and the steel cable passes through the exhaust pipe 405. The rotary joint is a prior art, so that when the drum 105 rotates, it does not affect the connection of the pipe 402. The installation method of the rotary joint is a prior art and will not be described here.

[0046] See also Figure 2 、 3 A mounting frame 404 is fixedly installed on the side of the support frame 102, and a mounting sleeve 403 is fixedly installed on the side of the mounting frame 404. The outer wall of one end of the exhaust pipe 405 is fixedly connected to the inner wall of the mounting sleeve 403. Two limiting rollers 406 are fixedly installed on the inner wall of the mounting frame 404, and the steel cable passes through the fingers of the two limiting rollers 406.

[0047] Example 5: Based on Example 1 or Example 2 or Example 3 or Example 4, see Figure 3 In one of the schemes, a reduction motor 103 is installed on the support frame 102, a first gear 104 is installed on the output shaft of the reduction motor 103, a second gear 202 is fixedly installed on the reel 105, the first gear 104 is engaged with the second gear 202, and the reel 105 is driven to rotate by the reduction motor 103.

[0048] In another embodiment, a rotating tube 201 is fixedly installed inside the reel 105, and both ends of the rotating tube 201 extend out of the reel 105 to form protruding axes at both ends of the reel 105. The cooling mechanism 3 is located inside the rotating tube 201, and a second gear 202 engaged with the first gear 104 is installed on the rotating tube 201.

[0049] Example 6: On the basis of Example 1 or 2 or 3 or 4 or 5, see Figure 1 The present invention further discloses an operating device, which adopts a hoisting device, and the drum 105 of the hoisting device is used for winding and installing a steel cable.

[0050] See also Figure 1A fixed block 101 is fixedly mounted on the top surface of the operating device 1 , and a support frame 102 is fixedly mounted on the top surface of the fixed block 101 . A steel cable is wound around a drum 105 .
