Description

Technical Field

[0001] The present invention relates to the field of cranes, and more particularly to a single-beam crane. Background Art

[0002] The single-beam crane is a lifting equipment that is horizontally mounted above workshops, warehouses and material yards to lift materials. Its two ends are located on tall concrete columns or metal supports. The beam of the single-beam crane runs longitudinally along the tracks laid on the elevated platforms on both sides. The space under the beam can be fully utilized to lift materials without being hindered by ground equipment. It is the most widely used and largest number of lifting machinery.

[0003] The most common problem of single-beam cranes is the rail gnawing phenomenon. The common reason for the rail gnawing phenomenon is mostly because the lifting mechanism is hanging the bottom material. The overall center of gravity of the lifting mechanism and the material is constantly changing when moving. The steel rope part pulling the material is unstable. When affected by the outside world, the lifting mechanism and the material are more likely to shake, which causes the walking mechanism to shake more easily when walking on the main beam, resulting in different pressures on the wheels of the walking mechanism located in the main beam track at different places on the track, resulting in the rail gnawing phenomenon.

[0004] When a single-beam crane is working, it uses a traveling mechanism to move along the main beam track on the single-beam crane. When the traveling mechanism starts to chew the track, the material on the main beam will be worn and produce debris. If the debris is pushed by the wheels on the track, noise will be generated. At the same time, the wear on the main beam track will increase. Therefore, the chewing track phenomenon directly affects the service life of the main beam. Summary of the invention

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

[0018] (1) The present invention provides a stabilizing rope, a pressure block group and a hanging wheel. When the traveling mechanism is started, stopped or turned, the steel rope rotates or shakes. While the steel rope rotates, the stabilizing rope located in the moving direction of the steel rope will be subjected to pressure and play a role at the same time, thereby achieving the effect of assisting the four steel ropes to remain stable and rotate at the smallest possible angle when the hook rotates. When the hook shakes, the steel rope on the hanging wheel will work together with the four stabilizing ropes to reduce the amplitude of the hook shaking, reduce the amplitude of the hook shaking when the single-beam crane is working, thereby reducing the degree of rail gnawing phenomenon, and further increasing the service life of the track.

[0019] (2) The present invention provides a main pressure block, an auxiliary pressure block and a lifting rope, and multiple pressure blocks are evenly distributed on the steel rope, which can effectively balance the weight of the steel rope part and the material part on the hook, thereby further increasing the stability of the entire steel rope part. The pressure block group can help disperse the weight of the hanging object, so that the load on each lifting rope is more uniform, which helps to reduce the local pressure on the steel rope, so that the amplitude of the steel rope shaking is further reduced when the walking mechanism is just started, stopped or turned.

[0020] (3) The present invention provides a vibration reduction assembly. When the traveling mechanism is started, stopped or turned, and the hook shakes unstably, the stabilizing rope will shake together with the rope of the hook. When the stabilizing rope starts to shake, the vibration reduction assembly starts to work, which helps to reduce the shaking of the hook. One end of the stabilizing rope is over-tightened, and the other end of the stabilizing rope is over-loose. The over-tightened end is in danger of breaking. Therefore, the stabilizing rope still has the function of maintaining the stability of the hook. To a certain extent, it can ensure that the four stabilizing ropes are at the same tension level, the force is more evenly applied, and the amplitude of the rope shaking is further reduced.

[0021] (4) The present invention provides a wire reel, a bellows, a first connecting pipe and an oil outlet pipe. When the hook shakes unstably, the contraction and extension of the bellows will cause the lubricating oil in the oil tank to flow out through the oil outlet pipe to the first connecting pipe. Subsequently, the lubricating oil is injected into the wire reel through the oil filling nozzle on the wire reel, thereby facilitating the wire reel to better release the steel rope, reducing vibration when releasing the steel rope, and further reducing the degree of shaking of the steel rope.

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0033] See also Figures 1 to 8A single-beam crane comprises a main beam 1, a traveling mechanism 2 is slidably arranged on the main beam 1, a lifting mechanism 3 is fixedly installed on the traveling mechanism 2, the lifting mechanism 3 is responsible for the actual lifting and lowering operations of the crane, the lifting mechanism 3 comprises a middle shell 33 fixedly installed on the traveling mechanism 2, a left shell 31 is fixedly installed on one end of the middle shell 33, a right shell 32 is fixedly installed on the other end of the middle shell 33, a wire reel 34 is arranged in the middle shell 33, a drive for making the wire reel 34 work is arranged inside the left shell 31, and a hook 35 is arranged below the middle shell 33 The wire reel 34 can be used to hoist the hook 35 through a steel rope. A hanging wheel 36 is fixedly installed on the middle shell 33, and a steel rope is slidably set on the hanging wheel 36. The bottom end of the steel rope on the wire reel 34 is used in conjunction with the hanging wheel 36. A stabilizing component 4 for enhancing the stability of the hook 35 is provided below the middle shell 33. The stabilizing component 4 includes stabilizing ropes 41 located on the outer surfaces of both sides of the left shell 31 and the right shell 32. The bottom ends of the four stabilizing ropes 41 are fixedly connected to a pressure block group 42. The pressure block group 42 is fixedly sleeved on the outer surface of the steel rope used to hoist the hook 35.

[0034] When the single-beam crane is working to transport materials, the walking mechanism 2 works with the materials lifted by the lifting mechanism 3 and moves along the direction of the main beam 1. The steel rope on the reel 34 lifts the materials on the hook 35, and the materials are lifted by the hook 35. In order to reduce the pressure of the steel rope used for lifting the hook 35 itself, the stabilizing rope 41 will share this part of the pressure to avoid the steel rope used for lifting the hook 35 from breaking due to excessive pressure. When the walking mechanism 2 is just started, stopped or turned, the steel rope will rotate or shake. While the steel rope is rotating, the stabilizing rope 41 located in the active direction of the steel rope will be under pressure and play a role at the same time, so as to achieve the effect of assisting the four steel ropes to remain stable and rotate as small as possible when the hook 35 rotates. Due to the setting of the hanging wheel 36, when the hook 35 shakes, it will work together with the four stabilizing ropes 41 to reduce the amplitude of the shaking of the hook 35 and the amplitude of the shaking of the hook 35 when the single-beam crane is working, thereby reducing the degree of rail gnawing phenomenon and increasing the service life of the track.

[0035] like Figures 1 to 4 As shown, the pressure block group 42 includes a main pressure block 421 slidably sleeved on the outer surface of the steel rope, and a plurality of auxiliary pressure blocks 422 are also slidably sleeved on the outer surface of the steel rope. The number of auxiliary pressure blocks 422 is at least greater than one, and the auxiliary pressure block 422 located at the bottom is fixedly sleeved on the outer surface of the steel rope. Four stabilizing ropes 41 are rotatably connected to the outer surface of the main pressure block 421. The main pressure block 421 and adjacent auxiliary pressure blocks 422 are fixedly connected by suspension ropes 423. Each adjacent auxiliary pressure block 422 is fixedly connected by suspension ropes 423. The suspension ropes 423 are arranged at the four corners of the main pressure block 421 and the auxiliary pressure blocks 422.

[0036] The four stabilizing ropes 41 are all rotatably connected to the four corners of the main pressure block 421, the steel rope sleeve used for hoisting the hoisting wheel 36 and the hook 35 is arranged in the central part of the pressure block group 42, and each adjacent auxiliary pressure block 422 is arranged equidistantly.

[0037] When the lifting mechanism 3 is working and the hook 35 is lowered to extend the steel rope on the hook 35, since the length of the hook 35 gradually increases at this time, the gravity of the material at the hook 35 is larger than the gravity of the rope 423, so the center of gravity of the material on the hook 35 will keep changing. When the walking mechanism 2 is just started, stopped or turned, the hook 35 will be unstable and shaken. When the lifting mechanism 3 is working and the hook 35 is lowered, due to the action of the stabilizing rope 41 fixed on the left shell 31 and the right shell 32, the main pressure block 421 will always remain at the same horizontal position height. At the same time, when the rope 423 is gradually extended, each auxiliary pressure block 422 will move away from each other. The main pressure block 421 and the adjacent secondary pressure block 422 will be separated and keep a certain distance under the action of the lifting rope 423, and each secondary pressure block 422 below will also keep the same distance. Since multiple pressure blocks are evenly distributed on the steel rope, the weight of the steel rope part and the material part on the hook 35 can be effectively balanced, thereby further increasing the stability of the entire steel rope part. At the same time, the pressure block group 42 can help disperse the weight of the hanging object, so that the load on each lifting rope 423 is more uniform, which helps to reduce the local pressure on the steel rope, so that the walking mechanism 2 can further reduce the amplitude of the steel rope shaking when it is just started, stopped or turned.

[0038] It should be noted that the steel rope hoisted by the hoisting wheel 36 is in a taut state, and the four stabilizing ropes 41 are also in the same state.

[0039] like Figure 5 and Figure 6 As shown, the left shell 31 and the right shell 32 are both provided with a vibration-damping assembly 5 used in conjunction with the stabilizing rope 41. The vibration-damping assembly 5 includes a sliding rod 51 fixedly connected to the stabilizing rope 41. A vibration-damping cavity 311 is provided inside the left shell 31 and the right shell 32. The sliding rod 51 can slide in the vibration-damping cavity 311. A vibration-damping spring 52 is also movably provided in the vibration-damping cavity 311. A limiting tube 53 is fixedly provided at the central part of the vibration-damping cavity 311. The limiting tube 53 is fixedly connected to the sliding rod 51 through the vibration-damping spring 52.

[0040] When the walking mechanism 2 is just started, stopped or turned, and the hook 35 is unstable and swaying, the stabilizing rope 41 will sway together with the sling rope 423 of the hook 35. When the stabilizing rope 41 starts to sway, the sliding rod 51 fixedly connected to the stabilizing rope 41 will enter and slide out of the vibration reduction chamber 311 due to the swaying of the stabilizing rope 41. At this time, the four stabilizing ropes 41 will all remain taut, which helps to reduce the swaying of the hook 35, one end of the stabilizing rope 41 is too tight, and the other end of the stabilizing rope 41 is too loose, and the over-tightened end may break.

[0041] Therefore, Figure 6 As shown in , when the hook 35 swings to the left, the stabilizing rope 41 on the right side will move to the left, and the stabilizing rope 41 that was originally over-tightened will change from an over-tightened state to a tight state under the action of the moving right-side slide bar 51, thereby reducing the probability of the stabilizing rope 41 breaking. At the same time, the stabilizing rope 41 on the left side will also move to the left, and the stabilizing rope 41 that was originally over-relaxed will change from an over-relaxed state to a tight state under the action of the moving left-side slide bar 51, thereby enabling it to still have the function of maintaining the stability of the hook 35, and to a certain extent, ensuring that the four stabilizing ropes 41 are at the same tension level, with more uniform force, further reducing the amplitude of the steel rope swing.

[0042] like Figure 5 and Figure 6 As shown, a retractable bellows 54 connected to the limiting tube 53 is movably provided in the vibration-damping chamber 311, and both ends of the limiting tube 53 are fixedly connected to the bellows 54. The bellows 54 is movably sleeved inside the vibration-damping spring 52, one end of the bellows 54 is fixedly connected to the limiting tube 53, and the other end of the bellows 54 is fixedly connected to the sliding rod 51.

[0043] A first connecting pipe 62 is fixedly inserted into one end of the limiting pipe 53 close to the middle shell 33, and a second connecting pipe 63 is fixedly inserted into one end of the limiting pipe 53 away from the middle shell 33. Both the first connecting pipe 62 and the second connecting pipe 63 are fixedly provided with a one-way valve inside one end close to the limiting pipe 53. The one-way valve inside the first connecting pipe 62 enables the first connecting pipe 62 to serve as the air outlet end of the limiting pipe 53.

[0044] An oil filling assembly 6 is provided inside the left shell 31, and the oil filling assembly 6 is used in conjunction with the bellows 54. The oil filling assembly 6 includes an oil tank 61 fixedly installed inside the left shell 31, and the oil tank 61 is used to place lubricating oil. An oil outlet pipe 64 is fixedly inserted at the bottom of the oil tank 61, and the oil outlet pipe 64 is connected to the second connecting pipe 63. An oil filling pipe 65 is fixedly inserted on one side of the oil tank 61, and the oil filling pipe 65 is connected to an external oil pipeline. The position of the oil filling pipe 65 mouth from the limit pipe 53 is farther than the position of the one-way valve in the second connecting pipe 63 from the limit pipe 53. The one-way valve inside the second connecting pipe 63 can make the second connecting pipe 63 serve as the air inlet end of the limit pipe 53, and the first connecting pipe 62 passes through the middle shell 33 and is connected to the oil filling nozzle of the reel 34.

[0045] When the hook 35 is Figure 6 When it shakes to the left as shown in the figure, the slide bar 51 moves to the left in the shock absorbing chamber 311, and the bellows 54 on the right side contracts, and the shock absorbing spring 52 contracts at the same time. When the bellows 54 contracts, the internal gas will be blown into the first connecting pipe 62 through the limiting pipe 53. After the gas passes through the first connecting pipe 62, the gas flow rate in the first connecting pipe 62 is too fast, resulting in a low air pressure in the first connecting pipe 62. At this time, the pipe opening at the bottom of the oil outlet pipe 64 is opened, and the lubricating oil in the oil tank 61 will flow out of the oil outlet pipe 64 to the first connecting pipe 62, and then the lubricating oil is injected into the wire reel 34 through the oil filling nozzle on the wire reel 34, so that the wire reel 34 can better release the steel rope, reduce the vibration when releasing the steel rope, and further reduce the degree of shaking of the steel rope.

[0046] It should be noted here that the structure of the nozzle of the oil filling tube 65 can be: a rubber sheet with an inwardly concave opening is provided at the bottom of the inner wall of the oil filling tube 65, and the opening on the rubber sheet is cross-shaped. This can be seen in major beverage bottle caps, and the mouth of medical bottles used in hospitals also has this design. In order to avoid the situation where the liquid flows out of the bottle mouth due to the fluidity and the influence of its own gravity, no further details will be given here.

[0047] like Figure 7 and Figure 8 As shown, two groups of chip pushers 8 are provided at both ends of the traveling mechanism 2, each group of chip pushers 8 is provided with two, and the two chip pushers 8 in the same group are symmetrically distributed up and down, and anti-derail blocks 7 are fixedly provided at both ends of the track for the traveling mechanism 2 to move on the main beam 1, the second connecting pipe 63 is a hose, and the second connecting pipe 63 is used in conjunction with the anti-derail blocks 7, and the chip pushers 8 are used in conjunction with the track for the traveling mechanism 2 to move on the main beam 1, and each chip pusher 8 is used in conjunction with the anti-derail blocks 7.

[0048] An air inlet cavity 73 which is respectively communicated with the two second connecting pipes 63 is provided inside each anti-derail block 7, a matching groove 71 is provided inside each anti-derail block 7, the matching groove 71 is used in conjunction with the track for the traveling mechanism 2 to move on the main beam 1, a feed cavity 72 is fixedly provided at the upper and lower ends of the matching groove 71, the feed cavity 72 is communicated with the air inlet cavity 73, and the outer end thickness of the feed cavity 72 gradually decreases.

[0049] Each chip pusher block 8 is provided with a plurality of fine holes, and each chip pusher block 8 is provided with a material guide groove 81. Each material guide groove 81 is used in conjunction with a track on the main beam 1 for movement of the walking mechanism 2. The inner walls of the upper and lower ends of each material guide groove 81 are inclined, and the guide groove is used in conjunction with the feed chamber 72.

[0050] When the traveling mechanism 2 is working, the debris on the track will be pushed away by the chip pusher block 8, and the debris will be stored in the guide groove through the inclined part on the inner wall of the guide groove of the chip pusher block 8, so as to prevent the traveling mechanism 2 from contacting the debris on the track and causing the rail gnawing phenomenon caused by the debris. When the traveling mechanism 2 stops working and resets, the chip pusher block 8 on the same side will contact the anti-derailment block 7, and the guide groove will be connected with the feed chamber 72. As the traveling mechanism 2 is just started, stopped or turned, causing the hook 35 to shake, such as Figure 6 As shown in , when the bellows 54 contracts, air is taken in through the second connecting pipe 63, and the second connecting pipe 63 inhales air through the air inlet cavity 73 of the anti-derail block 7, and then the debris in the guide groove is sucked into the air inlet cavity 73 through the feed cavity 72, completing the cleaning action of the debris on the track;

[0051] It should be noted here that the second connecting pipe 63 is inserted on the anti-derail block 7 and the limiting pipe 53. The second connecting pipe 63 can be pulled out by external force to clean the inside of the second connecting pipe 63 to remove the internal debris to prevent it from clogging the one-way valve inside the second connecting pipe 63 and affecting the normal air intake of the second connecting pipe 63.

[0052] Instructions for use: When the single-beam crane is working to transport materials, the traveling mechanism 2 works with the materials lifted by the lifting mechanism 3 and moves along the direction of the main beam 1. The steel rope on the reel 34 lifts the materials on the hook 35. The materials are lifted by the hook 35. In order to reduce the pressure of the steel rope used for lifting the hook 35, the stabilizing rope 41 will share this part of the pressure to avoid the steel rope used for lifting the hook 35 from breaking due to excessive pressure. When the traveling mechanism 2 is just started, stopped or turned, the steel rope will rotate or shake. While the steel rope is rotating, the stabilizing rope 41 located in the active direction of the steel rope will be under pressure and play a role at the same time, so as to achieve the effect of assisting the four steel ropes to remain stable and rotate as small as possible when the hook 35 rotates. Due to the setting of the hanging wheel 36, when the hook 35 shakes, it will work together with the four stabilizing ropes 41 to reduce the amplitude of the swing of the hook 35 and the amplitude of the swing of the hook 35 when the single-beam crane is working, thereby reducing the degree of rail gnawing and increasing the service life of the track.

[0053] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
