Description

Technical Field

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

[0002] Single-beam crane is a common industrial equipment, mainly used to move heavy objects in factories and warehouses. It usually consists of a single beam spanning a frame, with the ability to move up and down within a certain range, and the ability to lift and move goods through hooks and spreaders;

[0003] When the electric hoist on the single-beam crane drives the object to move, a certain amount of friction will be generated between the wheels and the rails. When the friction between the wheels and the rails continues to increase due to the influence of the crane itself (such as a lot of dust on the wheels or rails, wear on the rail surface caused by the wheels moving on the rails for a long time, etc.) and external factors (such as a heavy load on the electric hoist), it is easy for the equipment to bite the rails when transporting heavy objects, which reduces the stability and safety of the equipment during operation.

[0004] In addition, when the center of gravity of the object driven by the equipment is biased to one side, the friction between the wheel on that side and the track will be greater than the friction between the wheel on the other side and the track. At this time, when the equipment is moving the object, due to the influence of uneven loads on the wheels on both sides, it is also easy to cause track gnawing, which reduces the safety of the equipment in the process of transporting heavy objects. Therefore, it is urgent to design a single-beam crane to solve the above problems. Summary of the invention

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] (1) This solution has the advantages of sharing the load and improving the stability and smoothness of the equipment in the process of transporting heavy objects. When the load on the equipment increases and the friction between the wheels and the rails is large, the heat conduction mechanism can enable multiple cleaning rollers to cooperate to share the load on multiple wheels, which can effectively reduce the friction between the wheels and the rails and ensure the stable operation of the equipment. At the same time, in the process of multiple cleaning rollers cooperating to share the load, through cooperation with the lubrication mechanism, lubricating oil can be automatically applied to the surface of the rails and wheels, thereby further reducing the friction between the wheels and the rails and effectively increasing the service life of the wheels and the rails. When multiple cleaning rollers are located at the upper end of the corresponding wheels, the surface of the corresponding wheels can be automatically cleaned, thereby effectively improving the cleanliness of the surface of the wheels during continuous use and ensuring the smoothness of the equipment during continuous transportation of heavy objects.

[0023] (2) This solution has the advantage of uniform load, which further improves the stability of the equipment in the process of transporting heavy objects. When the center of gravity of the heavy object driven by the equipment is biased to one side, the height of the wheel on that side can be automatically adjusted according to the direction of the center of gravity deviation of the heavy object through the cooperation of multiple steel ropes with rings, discs, and push plates. This can achieve the effect of balancing the friction between the wheels on both sides of the equipment and the corresponding tracks, effectively reducing the occurrence of rail gnawing caused by the unstable center of gravity of the heavy object during equipment operation, effectively ensuring the stability and safety of the equipment in the process of moving heavy objects, and helping to increase the service life of the equipment.

[0024] (3) This solution has the advantage of preventing the heavy object from being continuously rotated and shaken by external forces during the movement process, thereby improving the safety of the equipment in the process of moving the heavy object. When the heavy object is rotated by factors such as wind during the movement process, the rotation of the heavy object can be limited by the correction component. At the same time, when the equipment drives the heavy object to start or the equipment accelerates or decelerates, causing the heavy object to swing back and forth, the swing limit of the heavy object can be achieved through the blocking component. This can effectively improve the safety of the equipment in the process of transporting heavy objects, and can reduce the energy loss of the equipment in the process of transporting heavy objects to a certain extent.

[0051] The adjustment assembly 5 includes a connecting ring 52 fixedly mounted at the lower end of the drum assembly 3, a housing 51 fixedly mounted at the lower end of the connecting ring 52, a supporting component is arranged in the housing 51, and two push plates 58 are mounted through the supporting component, a disc 55 is mounted in the housing 51 through a fixed component, a deviation correction assembly 6 is arranged on the disc 55, and a pressure lifting component is installed between the disc 55 and the four steel wire ropes 4;

[0052] The driving assembly 7 includes two support blocks 71 installed on the reel assembly 3, and a box body 72 is fixedly installed on the two support blocks 71.

The corresponding wire rope 4 can be wound and released through the forward and reverse rotation of the motor and the cooperation of the two drive rods and the four winding rods.

[0054] A hook is installed at the lower end of multiple steel wire ropes 4 (from Figure 1 As can be seen in the figure, when the equipment is required to lift a heavy object and transport it to a designated location (the heavy object needs to be placed vertically on the equipment body 1 to facilitate subsequent lifting of the hook. In addition, this equipment is a small single-beam crane, and the lifting capacity of a small single-beam crane is usually around 0.5 tons to 5 tons), the drum assembly 3 can be used to release multiple wire ropes 4 to drive the hook to start moving downward (such as Figure 1 When the hook moves to a suitable height and hooks the object, the wire rope 4 can be wound up by the drum assembly 3 to lift the heavy object to a specified height.

[0055] Reference Figure 1 - Figure 5 The supporting component includes a plurality of limit springs 57 fixedly mounted on the inner wall of the shell 51 , a support plate 56 is fixedly mounted between two corresponding limit springs 57 , and two push plates 58 are fixedly connected to the corresponding support plates 56 .

[0056] Reference Figure 1 - Figure 5 The fixed component includes a support roller 53 fixedly mounted on the inner wall of the shell 51, two fixed blocks are slidably mounted on the support roller 53, a fixed shaft 54 ​​is fixedly mounted between the two fixed blocks, and a disc 55 is rotatably mounted on the fixed shaft 54.

[0057] In the initial state, the plurality of limit springs 57 are in a compressed state, and the extrusion forces on the two ends and the upper and lower surfaces of the disc 55 facing the corresponding support plates 56 are equal, that is, the positioning of the disc 55 can be achieved through the plurality of support plates 56 at this time, ensuring that the disc 55 is in a horizontal state in the initial state, that is, ensuring that in the initial state, the upper ends of the two push plates 58 are at the same height.

[0058] Reference Figure 4 - Figure 8 The deviation-correcting component 6 includes a limiting opening evenly arranged in an annular shape on the disc 55, a box body 1 61 and a box body 2 62 are symmetrically fixedly installed inside the limiting opening, and the box body 1 61 and the box body 2 62 are distributed on both sides of the limiting opening, an air supply pipe 1 63 and an air supply pipe 2 64 are symmetrically fixedly connected between the box body 1 61 and the corresponding box body 2 62, and the air supply pipe 1 63 and the air supply pipe 2 64 are distributed on both sides of the corresponding box body 1 61 and the box body 2 62, a round rod 66 is slidably installed on the box body 1 61 and the box body 2 62, a plate body 67 is fixedly installed on the round rod 66, a reset spring 1 68 is fixedly installed on the plate body 67, and the reset spring 1 68 is fixedly connected to the corresponding box body 1 61 and the box body 2 62, a sealing plate 65 is fixedly installed on the round rod 66, and the sealing plate 65 is sealingly slidably installed in the corresponding box body 1 61 and the box body 2 62, and a blocking component is installed on the disc 55.

[0059] Reference Figure 3 - Figure 8 The pressure-lifting component includes two circular rings 510 respectively installed on the plurality of steel wire ropes 4 , and a compression spring 511 evenly distributed in an annular shape is fixedly installed between the two corresponding circular rings 510 , and two limiting rings 59 are fixedly installed between the two corresponding plate bodies 67 .

[0060] When the drum assembly 3 drives the multiple steel wire ropes 4 to move downward, the corresponding two rings 510 on the steel wire ropes 4 will move downward therewith (the friction between the corresponding two rings 510 and the corresponding steel wire ropes 4 is relatively large, that is, when the rings 510 are not blocked by the corresponding limiting rings 59, the rings 510 will move with the movement of the steel wire ropes 4 through the friction between the rings 510 and the corresponding steel wire ropes 4, and when the rings 510 are blocked by the corresponding limiting rings 59, the steel wire ropes 4 will be displaced relative to the corresponding rings 510), and the multiple rings 510 at the lower end are in contact with the corresponding limiting rings 59 at the lower end (such as Figure 6As shown in the direction, and applying downward pressure thereto, the plurality of limit rings 59 at the lower end will transfer part of the pressure to the disc 55. However, since the pressures applied to the disc 55 by the two ends of the disc 55, i.e., the two rings 510 on both sides, are equal, the disc 55 will not rotate at this time (the support roller 53 cooperates with the two fixing blocks to limit the position of the fixed shaft 54, and the fixed shaft 54 ​​can limit the position of the disc 55. Therefore, when the disc 55 is subjected to force, it can only rotate relative to the fixed shaft 54 ​​and will not move up or down, as shown in the direction shown in the direction, and downward pressure is applied thereto, the plurality of limit rings 59 at the lower end will transfer part of the pressure to the disc 55. However, since the pressures applied to the disc 55 by the two ends of the disc 55, i.e., the two rings 510 on both sides, are equal, the disc 55 will not rotate at this time (the support roller 53 cooperates with the two fixing blocks to limit the position of the fixed shaft 54, and the fixed shaft 54 ​​can limit the position of the disc 55). Therefore, when the disc 55 is subjected to force, it can only rotate relative to the fixed shaft 54 ​​and will not move up or down, as shown in the direction shown in the direction, and downward pressure is applied thereto, the plurality of limit rings 59 at the lower end will transfer part of the pressure to the disc 55. Figure 4 In the direction shown), at this time, the disc 55 generates a reaction force on the corresponding rings 510 through the multiple limiting rings 59 below, which can realize the movement limitation of the multiple rings 510, that is, at this time, the multiple steel wire ropes 4 will move downward relative to the corresponding rings 510.

[0061] When the drum assembly 3 is in operation to wind up the multiple steel wire ropes 4, driving the multiple steel wire ropes 4 to drive the corresponding rings 510 to move upward together, the multiple rings 510 at the top contact with the corresponding limit rings 59 at the upper end and push them (such as Figure 6 As shown in the direction, since the thrusts generated by the multiple rings 510 on both ends of the disk 55 are equal, the disk 55 will still remain in a horizontal state. At this time, the disk 55 can limit the movement of the corresponding rings 510 through the multiple limiting rings 59 located above.

[0062] When the center of the lifted weight is biased to one side, due to the different tensions borne by the steel wire ropes 4 on both sides, the contact forces between the wheels 78 on both sides and the corresponding slide rails are different, that is, the two wheels 78 with the center of the weight biased to one side will be subjected to greater vertical pressure, and according to Hooke's law, the increase in pressure perpendicular to the two surfaces will cause the contact area between these surfaces to increase, that is, at this time, the contact area between the two wheels 78 on this side and the corresponding track 2 increases, resulting in the friction force between the wheel 78 on this side and the track 2 being greater than the friction force between the wheel 78 on the other side and the corresponding track 2, which makes it easy for the multiple wheels 78 to cooperate in transporting the heavy objects and cause the track to gnaw.

[0063] "Rail gnawing" refers to the phenomenon of rail gnawing when the wheel 78 on the equipment contacts the track 2 and due to certain reasons (such as increased equipment load, excessive dust on the surface of the wheel 78 or the track 2, etc.), the wheel 78 produces abnormal wear or friction on the contact surface, resulting in obvious cutting or wear marks on the surface of the track 2. When the rail gnawing phenomenon occurs during the operation of the equipment, it will not only reduce the speed of the equipment movement, but also increase the safety of the equipment movement (increasing the instability of the crane during operation, thereby increasing the risk of accidents. For example, deformation of the track 2 may cause the equipment to jump or swing during driving, making it difficult for the operator to control it).

[0064] If the center of gravity of the heavy object lifted by the multiple steel wire ropes 4 is biased to the left (the offset angle of the heavy object is set to be small. If the offset angle of the heavy object is more obvious, the center position of the heavy object can be manually adjusted), at this time, during the process of the multiple steel wire ropes 4 being forced to move upward, the two steel wire ropes 4 on the left side will be subjected to greater tension, that is, the tension borne by the two steel wire ropes 4 on the left side will be greater than the tension borne by the two steel wire ropes 4 on the right side;

[0065] At this time, when the plurality of steel wire ropes 4 move upward so that the corresponding upper end circular ring 510 contacts the corresponding upper limit ring 59 and applies an upward thrust thereto (such as Figure 6 The thrust exerted by the two rings 510 on the left upper side to the left end of the disk 55 through the corresponding stop ring 59 will be greater than the thrust exerted by the two rings 510 on the right side of the disk 55 (as shown in the direction). Figure 5 direction), which will cause the disk 55 to rotate clockwise (as shown in the figure). Figure 4 In the direction shown, the disc 55 rotates with the fixed shaft 54 ​​as the axis), and during the rotation of the disc 55, the left end of the disc 55 pushes the corresponding support plate 56 upward, so that the support plate 56 on the upper left side drives the corresponding push plate 58 to move upward together (as shown in FIG. Figure 5 direction shown);

[0066] When the left push plate 58 moves upward, the two left wheels 78 can be moved up a certain distance by cooperating with the corresponding fixed plate 74 (since multiple limit springs 57 are initially in a compressed state, the two upper support plates 56 can be forced to move upward a smaller distance, that is, the corresponding push plate 58 and the two wheels 78 are driven to move up a smaller amplitude, the purpose is to ensure that in the process of adjusting the contact area between the wheel 78 and the track 2, the lower end of the wheel 78 can always be in contact with the surface of the corresponding track 2). In this way, the contact area between the two left wheels 78 and the corresponding track 2 can be reduced, that is, the friction between the two left wheels 78 and the corresponding track 2 is reduced, and the friction between the wheels 78 on both sides and the corresponding track 2 is balanced, which helps to maintain the stability and safety of the equipment during transportation (balanced load can effectively reduce the risk of accidents caused by unbalanced load), and reduce stress and load (uneven load distribution may cause certain components to be subjected to greater pressure or tension, increasing the risk of wear and damage. By balancing the load, these forces can be evenly dispersed and the service life of the equipment can be extended).

[0067] On the contrary, when the center of the weight is biased to the right (such as Figure 5 In the direction shown), the plurality of steel wire ropes 4 cooperate with the corresponding rings 510, which causes the disc 55 to rotate counterclockwise (as shown in FIG. Figure 5In the direction shown), that is, at this time, through the cooperation of the upper right support plate 56 and the corresponding push plate 58, the height of the right fixed plate 74 and the two wheels 78 can be adjusted, so that when the center of gravity of the hoisted heavy object is unstable, the height of the wheel 78 on this side can be automatically adjusted according to the offset direction of the center of gravity of the heavy object, so as to achieve the effect of balancing the friction between the wheels 78 on both sides and the corresponding track 2, which can effectively improve the stability and safety of the equipment in the process of transporting heavy objects.

[0068] The multiple wheels 78 are all made of polyurethane material. Polyurethane material has good wear resistance and quietness, which can effectively improve its service life. It is usually suitable for running on smooth ground and can withstand medium to heavy loads. In addition, polyurethane wheels have a certain elasticity. When subjected to external pressure, the polyurethane wheels will undergo elastic deformation, and when the pressure is released, they can return to their original state (that is, although the polyurethane wheel shell is usually harder, it can still undergo a certain degree of elastic deformation under high load conditions).

[0069] In addition, when the disc 55 rotates, one end of the disc 55 moves by squeezing and pushing the support plate 56 on one side, and the squeezing force of the other end of the disc 55 on the corresponding support plate 56 above will gradually decrease. At this time, under the action of the elastic force of the corresponding limit spring 57 itself, the side support plate 56 will drive the corresponding push plate 58 and the fixed plate 74 to move downward. However, since the position of the corresponding fixed plate 74 is limited by the side box body 72 and multiple limit rods 73 at this time, the side fixed plate 74 will react on the corresponding push plate 58 and the support plate 56, so that the side support plate 56 and the push plate 58 stay at the current height (that is, in the initial state, the position of the corresponding fixed plate 74 is limited by the box body 72, so that the fixed plate 74 limits the position of the corresponding support plate 56 through the corresponding push plate 58, that is, when the disc 55 is in a horizontal state, the height of the two upper support plates 56 is the lowest point of the movable position of the two).

[0070] If the multiple steel wire ropes 4 cooperate with the suspended weight to rotate in the air under the influence of factors such as wind, the weight will drive the multiple steel wire ropes 4 to rotate together. If the multiple steel wire ropes 4 rotate clockwise (such as Figure 7 In the direction shown), the steel wire rope 4 will pass through the corresponding two rings 510, push and stretch the corresponding two plates 67, the two round rods 66 and the two sealing plates 65 to push and pull. In this process, the sealing plate 65 located inside the box body 1 61 will compress the gas inside the box body 1 61 when it moves, and the sealing plate 65 located inside the box body 2 62 will continuously squeeze the gas on the left side of the box body 2 62 into the box body 1 61 through the corresponding gas pipe 1 63 when it moves, so that the density of the gas inside the box body 1 61 is continuously increased, and the air pressure is continuously enhanced.

[0071] As the gas density and pressure inside the box body 61 continue to increase, the reaction force (i.e., resistance) of the gas inside the box body 61 on the corresponding sealing plate 65 also continues to increase, thereby achieving the effect of limiting the rotation of the wire rope 4, that is, effectively reducing the situation where the heavy object drives the wire rope 4 to continue to rotate under factors such as wind, and effectively improving the stability of the multiple wire ropes 4 in the process of cooperating to drive the heavy object to move.

[0072] At the same time, when the multiple steel wire ropes 4 are forced to rotate clockwise (such as Figure 7 The deviation-correcting assembly 6 cooperates with the wire rope 4 to limit the rotation of the wire rope 4. When the wire ropes 4 stop rotating, the corresponding return spring 68 is elastically acted upon (the plate bodies 67 will stretch or compress the corresponding return spring 68 when they are moved under force), causing the plate body 67 to rotate counterclockwise to push the corresponding wire rope 4 to rotate and return to its original position (such as Figure 7 direction shown).

[0073] When the steel wire rope 4 is forced to rotate counterclockwise, the gas inside the second box body 62 will be continuously compressed, and the corresponding gas inside the first box body 61 will be continuously squeezed into the adjacent second box body 62, thereby achieving the effect of limiting the rotation of multiple steel wire ropes 4.

[0074] Reference Fig. 9 , Fig.10 The shift-blocking component includes a first rack 69 fixedly mounted on two fixed blocks respectively, two elastic telescopic rods 610 are fixedly mounted between the two first racks 69 and the shell 51, a plurality of elastic telescopic rods 611 are fixedly mounted in the shell 51, a second rack 612 is fixedly mounted between the corresponding two elastic telescopic rods 611, a baffle 613 is fixedly mounted on the two second racks 612, two rotating rods are rotatably mounted in the shell 51, rotating gears 614 are fixedly mounted on the two rotating rods, and the two first racks 69 and the two second racks 612 are meshed with the corresponding rotating gears 614.

[0075] When the multiple steel wire ropes 4 are forced to cooperate to lift the heavy object to start, or accelerate or decelerate the heavy object, the heavy object is affected by its own inertia and swings back and forth (such as Figure 1 The weight will drive the multiple steel wire ropes 4 to swing together, but the support rollers 53 and the fixed shaft 54 ​​limit the movement of the multiple steel wire ropes 4. At this time, the multiple steel wire ropes 4 will only move forward and backward under the force (such as Figure 5 In the direction shown), if the steel wire rope 4 is driven by the force to drive the disc 55, the fixed shaft 54, and the two fixed blocks to move to the left (as shown in FIG. Fig. 9The first rack 69 on the left will cooperate with the corresponding rotating gear 614, which will cause the second rack 612 on the left to drive the corresponding baffle 613 to move to the right to prevent the corresponding fixed block, the fixed shaft 54 ​​and the disc 55 from continuing to move left (as shown in the figure). Fig.10 In the direction shown, if the steel wire rope 4 is forced to move to the right, the cooperation of the first rack 69, the rotating gear 614, the second rack 612 and the baffle 613 on the right side can prevent the disc 55 and the multiple steel wire ropes 4 from continuously moving to the right, thereby effectively reducing the situation where the heavy object drives the steel wire rope 4 to continuously swing back and forth, and further improves the stability of the multiple steel wire ropes 4 in the process of cooperating with the displacement of the heavy object. In addition, by buffering the swing of the heavy object, it also helps to protect the equipment from unnecessary pressure and vibration, which not only helps to extend the service life of the equipment and reduce maintenance costs, but also reduces the energy consumption during the operation of the equipment (swaying will cause additional energy loss in the equipment during operation, because the equipment needs to consume more energy to adjust and balance the shaking caused by the movement of the heavy object).

[0076] At the same time, when the weight drives the steel wire rope 4 to move left and right (such as Fig. 9 The wheel 78 is prone to sliding or moving on the track 2 to a certain extent, especially when running at high speed or shaking greatly. The inertial force is more significant, which will affect the friction between the wheel 78 and the track 2, thereby increasing the stability of the equipment in the process of moving heavy objects and the probability of the equipment gnawing the track during operation. The invention can effectively improve the stability of the equipment in the process of transporting objects by timely limiting and correcting the swing of heavy objects.

[0077] Reference Fig.11 - Fig.13 The force transmission component includes a motor 75 fixedly mounted on a fixed plate 74, a rotating shaft 76 is fixedly mounted on the driving end of the motor 75, a transmission rod 77 is rotatably mounted on the fixed plate 74, and a wheel 78 on one side is fixedly mounted on the rotating shaft 76, and a wheel 78 on the other side is fixedly mounted on the transmission rod 77, a driving wheel is fixedly mounted on the rotating shaft 76, a driven wheel is fixedly mounted on the transmission rod 77, and a conveyor belt is installed between the driving wheel and the driven wheel.

[0078] When multiple steel wire ropes 4 cooperate to lift a heavy object, by starting two motors 75, two rotating shafts 76 and two transmission rods 77 can cooperate to drive multiple wheels 78 to roll and move on the corresponding tracks 2, so that the object can be moved to a specified position.

[0079] Reference Fig.11 - Fig.13The cleaning assembly 8 includes two arc-shaped plates 81 respectively fixedly mounted on the two fixed plates 74, each arc-shaped plate 81 is provided with an arc-shaped groove, each arc-shaped groove is fixedly mounted with a second return spring 86, each return spring 86 is fixedly mounted with a cylinder 82, each cylinder 82 is rotatably mounted with a rotating shaft 83, each drive disk 84 is fixedly mounted on the rotating shaft 83, and each drive disk 84 is fixedly mounted with a cleaning roller 85.

[0080] Reference Fig.11 - Fig.13 The heat conduction mechanism 87 includes two square plates fixedly mounted on the fixed plate 74, on which liquid storage cylinders 872 are fixedly mounted, on which heat conduction rods 873 are fixedly mounted, on which heat conduction sheets 871 are fixedly mounted, on which the two liquid storage cylinders 872 are fixedly mounted, and on which the two heat conduction rods 873 are fixedly mounted, and on which the two liquid storage cylinders 872 are fixedly connected tubes 874, in which pistons are sealed and slidably mounted, and on which the two pistons are fixedly mounted third racks 875;

[0081] Two rods (not shown but not labeled) are rotatably mounted on the fixed plate 74. Fig.13 As can be seen in the figure), parallel axis gears (drawn but not marked in the figure, from which the third rack 875 is meshed) are fixedly mounted on the two rods. Fig.13 As can be seen in the figure, winding rollers 876 are fixedly installed on the two rod bodies, traction ropes 877 are wound around the two winding rollers 876, and one end of the two traction ropes 877 is slidably installed on the corresponding arc plate 81, and one end of the two traction ropes 877 is fixedly connected to the corresponding cylinder 82.

[0082] In the initial state, the multiple traction ropes 877 are in a stretched state with respect to the corresponding cylinders 82 and the rotating shafts 83 (at this time, the corresponding return springs 86 of the cylinders 82 are in a stretched state), so that the multiple cleaning rollers 85 are located directly above the corresponding wheels 78. At this time, during the process of rolling displacement under force, the driving force applied by the wheels 78 to the corresponding driving disks 84 can make the corresponding rotating shafts 83 and the cleaning rollers 85 rotate together. During the rotation of the cleaning rollers 85, the dust and other impurities adhering to the corresponding wheels 78 can be cleaned, thereby effectively improving the cleanliness of the surface of the wheels 78, and effectively reducing the friction between the wheels 78 and the corresponding rails 2, as well as the occurrence of the rail gnawing phenomenon between the wheels 78 and the rails 2.

[0083] If the load carried by the device is large (i.e. the weight lifted is heavy), the friction between the wheels 78 and the track 2 will increase during the rolling displacement of the multiple wheels 78 on the corresponding track 2. In addition, if the load borne by the device remains unchanged, when the friction between the wheels 78 and the track 2 gradually increases, the surface temperature of the wheels 78 will also gradually increase due to the increase in friction. At this time, the heat transferred from the multiple heat conducting sheets 871 to the corresponding liquid storage cylinders 872 through the corresponding heat conducting rods 873 will increase accordingly (the multiple heat conducting sheets 871 are all in contact with the side walls of the corresponding wheels 78). When the temperature on the multiple liquid storage cylinders 872 gradually increases, the liquid inside them will gradually vaporize;

[0084] When the gas formed inside the plurality of liquid storage cylinders 872 enters the corresponding tube body 874 and increases continuously, the gas inside the tube body 874 will generate thrust on the corresponding piston and the third rack 875, so that the corresponding third rack 875 moves upward (such as Fig.13 In the process of the third racks 875 moving upward and cooperating with the corresponding parallel axis gears, the corresponding rods drive the winding rollers 876 to rotate and release the corresponding traction ropes 877. That is, at this time, under the elastic force of the return springs 86, the cylinders 82 can drive the corresponding rotating shafts 83, the driving discs 84 and the cleaning rollers 85 to rotate downward (as shown). Fig.13 In the direction shown), until the lower ends of the plurality of cleaning rollers 85 are in contact with the corresponding tracks 2;

[0085] When the lower ends of the multiple cleaning rollers 85 are in contact with the corresponding tracks 2, and the multiple wheels 78 still cooperate with the corresponding driving discs 84 and the rotating shafts 83 to drive the corresponding cleaning rollers 85 to rotate, the effect of load sharing can be achieved. That is, at this time, part of the load applied to the multiple wheels 78 by the reel assembly 3 itself and the heavy objects hoisted at the lower end will be shared by the multiple cleaning rollers 85. At this time, the friction between the multiple wheels 78 and the corresponding tracks 2 can be effectively reduced through the cleaning rollers 85, and the occurrence of rail gnawing caused by the increase in load and the increase in friction between the multiple wheels 78 and the tracks 2 can be reduced, thereby further improving the stability of the multiple wheels 78 in the process of cooperating in the transmission of heavy objects.

[0086] The liquid stored in the multiple liquid storage cylinders 872 can specifically be ether (boiling point is about 34.6 degrees Celsius). Ether is liquid at room temperature. When the temperature gradually rises (when the temperature rises to close to or exceeds its boiling point, that is, about 30 degrees Celsius, the ether will change from liquid to gas), the ether will change from liquid to gas. This process is usually called vaporization or evaporation. When the temperature gradually returns to room temperature, the vaporized liquid will condense into liquid again.

[0087] In addition, when the cleaning roller 85 rolls and moves on the track 2, and the push plate 58 is forced to push the corresponding wheel 78 upward, the corresponding cleaning roller 85 will also move upward. However, since the upward arc is small, when the height of the wheel 78 is adjusted, the lower end of the cleaning roller 85 will still contact the surface of the corresponding track 2.

[0088] Reference Fig.11 , Fig.15 , Fig.16 The lubrication mechanism includes a liquid supply box 9 fixedly installed in the box body 72, two storage boxes 11 are fixedly installed in the box body 72, and a liquid infusion tube 10 is fixedly connected between the two storage boxes 11 and the liquid supply box 9, and a partition 12 is fixedly installed in the two storage boxes 11, and three linearly evenly distributed return springs are fixedly installed on the two partitions 12, and a fixed frame 13 is fixedly installed on the return springs three, and the two fixed frames 13 are sealed and slidably installed in the corresponding storage boxes 11;

[0089] Sponges 14 are fixedly mounted on the two fixed frames 13, liquid inlets are opened on the two partitions 12, and blocking push rods 15 are fixedly mounted on the two fixed frames 13, and one end of the two blocking push rods 15 is sealed and slidably mounted on the corresponding liquid inlets.

[0090] In the process that the multiple rotating shafts 83 are driven by the corresponding driving disks 84 and the cleaning rollers 85 to rotate and move downward, the driving disks 84 will generate a thrust to the right side on the corresponding fixing frame 13 (such as Fig.16 As shown in the direction, the corresponding fixed frame 13 drives the corresponding sponge 14 and the blocking push rod 15 to move to the right together (in this process, the fixed frame 13 will continuously compress the corresponding return spring 3). When the right end of the blocking push rod 15 moves out of the corresponding liquid inlet, the lubricating oil on the right side of the corresponding partition 12 (such as Fig.16 In the direction shown, the two liquid supply boxes 9 are both connected with connecting pipes, and the staff can use the existing conveying equipment to convey the lubricating oil to the two liquid supply boxes 9, and the lubricating oil stored in the two liquid supply boxes 9 can be replenished with lubricating oil in the corresponding two storage boxes 11 through the corresponding two infusion pipes 10) and enter the left side of the partition 12 through the liquid inlet to soak the corresponding sponge 14;

[0091] When the cleaning roller 85 rotates and contacts the corresponding sponge 14 and stops rotating, the cleaning roller 85 will squeeze the soaked sponge 14 and smear the lubricating oil on the soaked sponge 14 onto the cleaning roller 85. During the force rotation process, the cleaning roller 85 coated with lubricating oil will smear the lubricating oil on the corresponding track 2 and wheel 78, thereby reducing the friction between the wheel 78 and the corresponding track 2, effectively improving the service life of multiple wheels 78, and effectively reducing the gnawing of the track due to the increase in friction between the multiple wheels 78 and the corresponding track 2, thereby reducing the stability and safety of the equipment during the transportation of heavy objects.

[0092] At the same time, when the friction between the wheel 78 and the corresponding track 2 gradually decreases, the temperature of the surface of the wheel 78 will also gradually decrease. That is, the temperature transmitted from the corresponding heat conducting sheet 871 to the corresponding liquid storage cylinder 872 will gradually decrease, and the surface temperature of the liquid storage cylinder 872 will gradually return to normal temperature. The gas inside the liquid storage cylinder 872 will also be converted back to liquid. At this time, the corresponding piston and the third rack 875 will move down and reset under the action of their own elastic force (such as Fig.13 In the process of the third rack 875 moving down and resetting, the corresponding traction rope 877 will be reeled in through the cooperation with the corresponding parallel axis gear and the reeling roller 876, so that the traction rope 877 stretches the corresponding cylinder 82, the rotating shaft 83 and the cleaning roller 85 to rotate and reset.

[0093] Instructions for use: In the process of lifting and moving the heavy object to the designated position by the device, the surfaces of the corresponding wheels 78 can be cleaned by the multiple cleaning rollers 85. At the same time, if the multiple wheels 78 roll and displace on the corresponding track 2 or the equipment load is large, the friction between the wheels 78 and the track 2 gradually increases, and the surface temperature of the multiple wheels 78 gradually increases. At this time, the multiple cleaning rollers 85 can be rotated and moved down to the top of the corresponding track 2 (such as Fig.15 In the direction shown), load distribution can be achieved, reducing the effect of friction between the wheel 78 and the track 2.

[0094] At the same time, during the process of multiple cleaning rollers 85 rotating and moving downward, the corresponding fixed frame 13 and sponge 14 will be squeezed, and the lubricating oil in the sponge 14 will be squeezed onto the corresponding cleaning roller 85. At this time, during the process of multiple cleaning rollers 85 rotating on the corresponding track 2, the lubricating oil on them will be smeared on the corresponding track 2 and the wheel 78, thereby further reducing the friction between the track 2 and the wheel 78, effectively improving the service life of the wheel 78 and the reliability of the equipment during continuous use.

[0095] At the same time, if the center of gravity of the heavy object lifted by the equipment is biased to one side, and the friction between the two wheels 78 on this side and the corresponding track 2 is greater than that on the other side, the tension borne by the two steel wire ropes 4 on this side will be greater than that of the two steel wire ropes 4 on the other side. At this time, the thrust of the corresponding rings 510 of the two steel wire ropes 4 on this side on one end of the disc 55 will cause this end of the disc 55 to rotate upward. During the upward rotation of one end of the disc 55, the two wheels 78 on this side can be moved up a certain distance through the cooperation of the corresponding support plate 56, the push plate 58 and the fixed plate 74, thereby achieving uniform load and balancing the friction between the wheels 78 on both sides and the corresponding track 2.

[0096] In addition, if the equipment is in the process of moving an object and is affected by other factors such as wind, causing the heavy object to drive the multiple steel wire ropes 4 to rotate in the air, the cooperation between the multiple steel wire ropes 4 and the correction component 6 can achieve the limitation of the rotation distance of the multiple steel wire ropes 4 and promote their rotational reset. At the same time, if the equipment drives the object to start or accelerate or decelerate, and the heavy object drives the multiple steel wire ropes 4 to swing back and forth, the cooperation between the multiple steel wire ropes 4 and the disc 55 and the blocking component can achieve the limitation of the swing distance of the multiple steel wire ropes 4, thereby effectively increasing the stability and safety of the equipment in the process of transporting heavy objects.

[0097] 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.
