[0015] In order to solve the above technical problems, the present invention also provides a method for hoisting a communication base station tower mast, comprising the following steps: S1: Fix one end of the rope to the crane drum, pass the other end of the rope through the safe, and pass it around the multiple second pulleys inside the safe in sequence. During the process of passing, make sure the rope fits well with the second pulley to avoid slipping or jamming.

Since the communication base station tower mast hoisting operation is usually carried out at high altitude, the hoisting rope breaks and causes the hoisting device to fall, endangering the safety of people on the ground. When the hoisting rope breaks, the device can quickly brake in an emergency situation, so that the two first plug rods are thrown out and stuck in the limiting grooves, avoiding injuries to people and preventing the hoisting device from being damaged due to falling. At the same time, it can avoid a series of chain reactions caused by the hoisting device falling to damage surrounding communication equipment or other facilities, such as damaging surrounding facilities and affecting communication signal transmission, thereby ensuring the normal construction or maintenance of the communication base station. Through the coordination of the main oil tank, the injection pipe, the oil extraction pipe, the second one-way valve, the oil extraction cylinder, the push-pull rod, the first motor, the fixed seat, the turntable, the connecting rod, the piston and the electronic valve, when the lubricant is extracted, it is sprayed out through the electronic valve, which can make the pulley rotate more flexibly, make the lifting process smoother, and improve work efficiency. The lubricant can also reduce the friction coefficient between components, reduce vibration and noise, make the first pulley run more smoothly, and improve the safety and reliability of the lifting operation. Through the coordination of the first one-way valve, the oil pipeline, the pressure sensor, the extrusion plug, the second spring, the sliding rod, the chamber and the flow port, the amount of lubricant extracted can be accurately controlled to ensure that the amount of lubricant sprayed each time is appropriate, and waste due to excessive extraction can be prevented. The stable supply of lubricant helps to maintain the consistent lubrication state of the pulley group, making the equipment operation more stable and reliable, and reducing the probability of failure due to unstable lubrication.

[0017] The present invention provides a method for hoisting a communication base station tower mast. By adopting the above-mentioned communication base station tower mast hoisting equipment to hoist the communication base station tower mast, the hoisting work of the communication base station tower mast is greatly facilitated, which is beneficial to avoid damage to the hoisting equipment due to falling, protect the personnel under the equipment, and prevent the operating personnel from facing greater psychological pressure and affecting work efficiency.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] First embodiment: Please refer to Figure 1-Figure 7In the first embodiment of the present invention, the communication base station tower mast hoisting equipment includes: a hook 1, a support plate 2, a first pulley 3, a hook body 4, two first rotating shafts 7 and a lifting rope 6. The first pulley 3 is rotatably installed in the hook body 4, the support plate 2 is fixedly installed in the hook body 4, the two first rotating shafts 7 are respectively fixedly installed at both ends of the first pulley 3, the lifting rope 6 is wound on the outer wall of the first pulley 3, the hook 1 is rotatably installed at the bottom of the hook body 4, and a safe 5 is fixedly installed on the top of the hook body 4. A plurality of second pulleys 12 are provided in the safe 5, and a first gear 9 is fixedly installed on the outer wall of the plurality of second pulleys 12. Any two adjacent first gears 9 are meshed with each other, and the first gears 9 fixed through the outer wall are meshed with each other. When one of the second pulleys is rotated 12, due to the gear meshing transmission, the other second pulleys 12 will rotate synchronously, thereby the winding path and force direction of the lifting rope 6 on the second pulley 12 can be flexibly changed to adapt to lifting scenes of different heights and angles, optimize the force distribution of the lifting rope 6, and improve the lifting stability. Two limiting covers 11 are fixedly installed in the safe 5, and multiple limiting grooves 16 are provided on the inner walls of the two limiting covers 11. Through the multiple limiting grooves 16, the locking rod 15 can lock the second pulley 12 at multiple angles to avoid rotating multiple times to lock the second pulley 12. Second rotating shafts 10 are fixedly installed at both ends of multiple second pulleys 12, and both ends of multiple second rotating shafts 10 are rotatably connected to the safe 5, two of which are second The rotating shafts 10 all pass through the corresponding limiting covers 11 and are rotatably connected to the limiting covers 11, and a locking rod 15 is fixedly installed on the second rotating shaft 10 located in the limiting cover 11, and a first plug rod 14 and a second plug rod 22 are slidably installed in the locking rod 15, and the ends of the first plug rod 14 and the second plug rod 22 away from each other are extended to the outside of the locking rod 15 and are fixedly installed with a first clamping block 13. Since the tower mast hoisting operation of the communication base station is usually carried out at high altitude, the breakage of the lifting rope 6 causes the hoisting equipment to fall, endangering the safety of the ground personnel. When the lifting rope breaks, the safe 5 drops sharply, and the second pulley 12 will rotate rapidly due to friction contact with the lifting rope 6. Due to the gear meshing transmission, the other second pulleys 12 will rotate synchronously, and the second pulley 1 The locking rod 15 is driven to rotate by the second rotating shaft 10, and the first insertion rod 14 and the second insertion rod 22 in the locking rod 15 are thrown out. When they are thrown out a certain distance, the second clamping block 19 slides into the second insertion hole 23 through the inclined surface and is stuck. A pin shaft hole 17 is provided in the first insertion rod 14, and a sliding groove 18 is provided on one side of the pin shaft hole 17. A positioning rod 21 is fixedly installed at one end of the second insertion rod 22 close to the first insertion rod 14. One end of the positioning rod 21 extends into the pin shaft hole 17, and a second clamping block 19 is slidably installed at the end of the positioning rod 21 located in the pin shaft hole 17. A third spring 46 is fixedly installed in the positioning rod 21, and the third spring 46 can push the second clamping block 19 into the second insertion hole 23 and the sliding groove 18.The other end of the third spring 46 is fixedly connected to the second clamping block 19, and the second clamping block 19 is located in the slide groove 18. When the locking rod 15 rotates, the second clamping block 19 can be moved and retracted into the limiting groove by the first inclined surface on the slide groove 18 and the weight of the first clamping block 13. When the two first clamping blocks 13 are inserted into the limiting groove 16, the second clamping block 19 pops out and is stuck in the second insertion hole 23. The outer side of the positioning rod 21 is sleeved with a first spring 20. The two ends of the first spring 20 are respectively fixedly connected to the second insertion rod 22 and the first insertion rod 14. When the second clamping block 19 is pushed into the limiting groove using a tool, the second insertion rod 22 and the first insertion rod 14 can be moved relative to each other by resetting the first spring 20, and the second clamping block 19 can be moved into the slide groove 18 again.

[0022] First bearings are rotatably mounted on the outer walls of both ends of the second rotating shaft 10, and the outer walls of the first bearings are fixedly mounted in the safe 5. The first bearings mounted on the outer walls of both ends of the second rotating shaft 10 significantly reduce the friction resistance when the second pulley 12 rotates in the safe 5.

[0023] A second socket 23 is provided on the first plug rod 14, a third socket 24 is provided on the locking rod 15, and a plurality of first sockets 8 are provided on the safe 5. The second socket 23, the third socket 24 and the first socket 8 are all connected. When it is not necessary to fix the second pulley 12, a tool is inserted into the first socket 8, the third socket 24 and the second socket 23, and the second block 19 is pushed inward into the limit groove. Subsequently, the first spring 20 is reset to move the positioning rod 21 to a certain distance, and the second block 19 is pushed out of the positioning rod 21 by the third spring 46 and extends into the slide groove 18.

[0024] A first inclined surface is provided on the inner wall of the sliding groove 18 on the side close to the second insertion rod 22, and a second inclined surface is provided on the side of the second blocking block 19 close to the first inclined surface. The first inclined surface and the second inclined surface cooperate with each other. Through the cooperation of the first inclined surface and the second inclined surface, when the locking rod 15 rotates rapidly, the second blocking block 19 can more conveniently extend into the limiting groove.

[0025] One end of the positioning rod 21 located in the pin shaft hole 17 is provided with a limiting groove, and one end of the third spring 46 and the second clamping block 19 are both disposed in the limiting groove.

[0026] The working principle of the communication base station tower mast hoisting equipment provided by the present invention is as follows: Pass one end of the lifting rope 6 through the first pulley 3 in the hook body 4, wrap it around the outer wall of the first pulley 3, and pass the other end of the lifting rope 6 around the multiple second pulleys 12 in the safe 5 in turn, so that the lifting rope 6 is fully fitted with the second pulley 12, and the hook 1 is hung on a suitable lifting point of the communication base station tower mast equipment to be hoisted, start the hoisting equipment, and slowly lift the communication base station tower mast equipment. When the lifting rope 6 suddenly breaks, the safe 5 drops sharply, and the second pulley 12 rotates rapidly due to friction contact with the lifting rope 6. Due to the gear meshing transmission, the other second pulleys 12 rotate synchronously, and the second pulley 12 drives the locking rod 15 to rotate through the second rotating shaft 10, and the first plug rod 14 and the second plug rod 22 in the locking rod 15 are thrown out. When they are thrown out a certain distance When the second pulley 12 needs to be released, a tool is used to insert the first hole 8, the third hole 24 and the second hole 23 to push the second block 19 out of the second hole 23. Then, the first spring 20 is reset to pull the second rod 22 and the first rod 14 into the locking rod 15, so that the first block 13 is away from the limiting groove 16. At this time, the second rotating shaft 10 can rotate.

[0027] Second embodiment: Based on the communication base station tower mast hoisting device provided in the first embodiment of this application, the second embodiment of this application proposes another communication base station tower mast hoisting device. The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0028] The second embodiment of the present invention will be further described below with reference to the accompanying drawings and implementation plans.

[0029] Please refer to Figures 8-11The communication base station tower mast hoisting equipment also includes a main oil tank 26, which is fixedly installed on the bottom of the support plate 2, and an injection pipe 25 is fixedly installed on one side of the main oil tank 26, and oil extraction pipes 27 are fixedly installed on both sides of the main oil tank 26, and oil extraction cylinders 31 are fixedly installed on both sides of the hook body 4, and a second one-way valve 35 is fixedly installed on one end of the oil extraction cylinder 31, and one end of the oil extraction pipe 27 is fixedly connected to the water inlet end of the second one-way valve 35, and a fixing seat 29 is fixedly installed on both sides of the hook body 4, and a pressure sensor 45 is fixedly installed in the two fixing seats 29. When one end of the sliding rod 37 contacts the pressure sensor 45, the first motor 30 stops. The oil pump 31 stops working and no longer drives the turntable 44 to rotate. At this time, the lubricant is no longer extracted to prevent the excessive amount of lubricant in the auxiliary oil tank 34. The two fixed seats 29 are fixedly installed with the first motor 30 on the side away from each other. The output shaft of the first motor 30 extends into the fixed seat 29 and is fixedly installed with the turntable 44. One side of the turntable 44 is hinged with one end of the connecting rod 43. The piston 42 is slidingly sealed in the oil pumping cylinder 31. One side of the piston 42 is fixedly installed with one end of the push-pull rod 36. The other end of the push-pull rod 36 extends to the outside of the oil pumping cylinder 31. The other end of the connecting rod 43 is rotatably connected to the end of the push-pull rod 36 located outside the oil pumping cylinder 31. Then, auxiliary oil tanks 34 are fixedly installed on both sides of the hook body 4, and first one-way valves 28 are fixedly installed on the outer walls of the two oil pumping cylinders 31. One end of an oil delivery pipe 38 is fixedly installed on the water outlet end of the first one-way valve 28, and the other end of the oil delivery pipe 38 is fixedly connected to the auxiliary oil tank 34. An extrusion plug 41 is slidingly sealed in the auxiliary oil tank 34, and one end of a sliding rod 37 is fixedly installed on one side of the extrusion plug 41. The other end of the sliding rod 37 extends to the outside of the auxiliary oil tank 34. A chamber 40 is provided in each of the two auxiliary oil tanks 34, and a flow port 39 is provided on both sides of the chamber 40. An electronic valve 32 is fixedly installed on the bottom of the auxiliary oil tank 34. When the turntable 44 rotates, the push-pull rod 36 is pulled by the hinged connecting rod 43, causing the piston 42 to perform reciprocating linear motion in the oil pumping cylinder 31. When the piston 42 moves outward, the internal space of the oil pumping cylinder 31 increases and the air pressure decreases. At this time, the second one-way valve 35 opens, and the lubricant in the main oil tank 26 flows into the oil pumping cylinder 31 through the oil pumping pipe 27 under the action of atmospheric pressure. When the piston 42 moves inward, the second one-way valve 35 closes to prevent the lubricant from flowing back. At the same time, the first one-way valve 28 opens, and through the continuous reciprocating motion of the piston 42, the lubricant in the main oil tank 26 is continuously extracted and transported to the auxiliary oil tank 34. The second one-way valve 35 and the first one-way valve 28 are used to prevent the lubricant from flowing back.

[0030] The end of the pumping cylinder 31 away from the second one-way valve 35 is provided with a first opening, a first sealing ring is fixedly installed in the first opening, and the push-pull rod 36 is slidably and sealingly connected to the pumping cylinder 31 through the first sealing ring.

[0031] A second spring 33 is sleeved on the outer side of the sliding rod 37. The two ends of the second spring 33 are fixedly connected to the extrusion plug 41 and the auxiliary oil tank 34 respectively. When the lubricant in the auxiliary oil tank 34 is insufficient, the extrusion plug 41 can be moved to its original position by resetting the second spring 33.

[0032] The auxiliary oil tank 34 is provided with a second opening on a side away from the electronic valve 32, and a second sealing ring is fixedly installed in the second opening. The sliding rod 37 is slidingly and sealingly connected to the auxiliary oil tank 34 through the second sealing ring. The second sealing ring can prevent the lubricant from overflowing along with the sliding rod 37 when the sliding rod 37 slides left and right.

[0033] The first motor 30 drives the turntable 44 to rotate in the fixed seat 29 through the output shaft. When the turntable 44 rotates, the push-pull rod 36 is pulled by the hinged connecting rod 43, so that the piston 42 performs reciprocating linear motion in the oil pumping cylinder 31. When the piston 42 moves outward, the internal space of the oil pumping cylinder 31 increases and the air pressure decreases. At this time, the second one-way valve 35 opens, and the lubricant in the main oil tank 26 flows into the oil pumping cylinder 31 through the oil pumping pipe 27 under the action of atmospheric pressure. When the piston 42 moves inward, the second one-way valve 35 closes to prevent the lubricant from flowing back. At the same time, the first one-way valve 28 opens, and the lubricant in the oil pumping cylinder 31 is pressed into the auxiliary oil tank 34 through the oil delivery pipe 38. Through the continuous reciprocating motion of the piston 42, the lubricant in the main oil tank 26 is continuously extracted and delivered The lubricant is then sent to the auxiliary tank 34, which is used to store the extracted lubricant. After the oil pipe 38 injects the lubricant into the auxiliary tank 34, the extrusion plug 41 slides along the inner wall of the auxiliary tank 34 under the action of the lubricant pressure. When the lubricant in the auxiliary tank 34 increases and the pressure increases, the extrusion plug 41 compresses the second spring 33, causing the sliding rod 37 to move toward the pressure sensor 45. When the sliding rod 37 contacts the pressure sensor 45, the first motor 30 no longer drives the turntable 44 to rotate and no longer extracts lubricant. Subsequently, the lubricant in the auxiliary tank 34 flows into the chamber 40, and the lubricant in the chamber 40 flows to the bottom of the auxiliary tank 34 through the flow ports 39 on both sides. Under the action of gravity and the pressure in the auxiliary tank 34, the lubricant is sprayed onto the first rotating shaft 7 through the electronic valve 32.
