[0001] The invention relates to the technical field of overhead crane shells, in particular to an overhead mobile crane. Background Art

[0002] A crane refers to a multi-action lifting machinery that can vertically lift and horizontally move heavy objects within a certain range. An overhead crane is a lifting equipment used in warehouses. An overhead crane has elevated frames on both sides of the warehouse, and horizontally movable cross bars on the elevated frames, and a horizontally movable Hulusi lifter is installed on the cross bars. Through this design, flexible positioning and transportation of goods in the warehouse can be achieved.

[0003] The common overhead mobile cranes on the market have poor handling stability. During the handling process, there are usually staff working in the warehouse. If the handling route overlaps with the staff route, the transported goods are very likely to collide with the staff, which has a great impact on the handling stability and the working safety of the equipment.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an overhead mobile crane is proposed. Summary of the invention

[0007] Furthermore, the cross bar assembly includes a rod body, a slide groove, a first electric push rod, a displacement plate and a locking tooth. The slide grooves are opened on both sides of the inner side of the rod body, and the first electric push rod is arranged on both sides of the inner side of the rod body. The output end of the first electric push rod is connected to the displacement plate, and the outside of the displacement plate is connected to the locking tooth.

[0008] Furthermore, the rod body is rotatably connected to the lifting seat via a rotating shaft, and the hydraulic cylinder drives the lifting seat to move up and down.

[0009] Furthermore, the displacement plate and the slide groove have the same height, and the engaging teeth are distributed in an array on the surface of the displacement plate.

[0010] Furthermore, the transverse movement assembly includes a transverse movement frame, a driving wheel and a rack. The driving wheels are arranged on both sides of the interior of the transverse movement frame, and the transverse movement frame is connected to a rack near the slide groove.

[0011] Furthermore, the transverse moving frame and the rack are integrated, and the rack is meshed with the engaging teeth.

[0012] Furthermore, the lifting assembly includes a lifting box, a lifting chain, a connecting plate, a hook, a first damping shaft, a damping telescopic rod and a second damping shaft. The lifting chain is connected to the inside of the lifting box, and a connecting plate is provided at the end of the lifting chain. The bottom outer side of the connecting plate is connected to the hook, and the top of the connecting plate is provided with a first damping shaft. The top outer side of the first damping shaft is connected to the damping telescopic rod, and the top of the damping telescopic rod is located on the surface of the lifting box and is connected to the second damping shaft.

[0013] Furthermore, the lower pressure seat is fixedly connected to the lifting box, and the lower pressure seat is elastically connected to the pressure spring.

[0014] Furthermore, the first damping rotating shaft is distributed in a ring shape at the top end of the hook, and the damping telescopic rod is rotatably connected to the first damping rotating shaft and the second damping rotating shaft.

[0015] Furthermore, the sliding seat is sleeve-connected with the transverse moving frame, and the sliding seat and the sleeve frame are fixed by welding.

[0016] The present invention provides an overhead mobile crane, which has the following beneficial effects:

[0017] 1. The present invention can drive the lifting seat to lift by operating the hydraulic cylinder. During the lifting process, the lifting seat can make the rod body appear inclined by rotating the rotating shaft. The equipment can make the inclined surface face the direction according to the transportation direction of the goods. By making the rod body appear inclined and then trying to displace the driving wheel, the movement resistance of the driving wheel can be greatly reduced, which can effectively improve the convenience of the equipment for transporting goods. In addition, when the equipment is in the process of transporting goods, if there are workers passing by on the goods movement route, the first electric push rod can drive the displacement plate to move, so that the displacement plate can drive the engaging teeth at its outer end to move closer to the rack on the inner side of the transverse frame, so that the engaging teeth can mesh with the rack, and when the engaging teeth mesh with the rack, the lateral displacement of the transverse frame can be locked suddenly, which avoids the situation that the driving wheel stops working, but the transverse frame continues to move due to inertia and collides with the workers on the route, which can effectively improve the safety of the equipment.

[0018] The camming member is then moved to a position opposite to the direction in which the load is lifted and the load is then moved relative to the load carrier, thereby preventing the load carrier from being moved to a position opposite to the direction in which the load is lifted.

[0019] 3. After the goods of the present invention are hoisted on the hook, the weight of the goods will generate a downward pulling force on the lifting box, and the lifting box is fixed to the lower pressure seat. This allows the lifting box to drive the lower pressure seat to squeeze the pressure spring and move downward together when subjected to the downward pulling force. If the goods lifted on the hook are too heavy, the lower pressure seat will move down to the fixed frame due to the excessive downward pulling force, and contact the pressure sensor. When the pressure sensor senses the pressure, it means that the goods lifted on the surface hook are too heavy. This allows the staff to quickly determine whether the goods are too heavy during the process of hoisting the goods, thereby avoiding equipment damage caused by excessive weight of the goods. In addition, by twisting the wire lever, the wire lever can be raised and lowered in the fixed frame, and the wire lever can drive the pressure sensor to adjust the height during the lifting process, which allows the equipment to adjust different overweight benchmarks according to different hoisted goods, which improves the flexibility of the equipment. In addition, the pressure spring can play a shock-absorbing role in the process of moving the goods, reducing the vibration transmitted to the goods during the movement of the rolling wheel and the transverse frame, which further improves the mobile stability of the equipment.

The lower pressure seat 13 is fixedly connected to the lifting box 1801, and the lower pressure seat 13 is elastically connected to the pressure spring 14. The first damping shaft 1805 is distributed in a ring shape at the top of the hook 1804, and the damping telescopic rod 1806 is rotatably connected to the first damping shaft 1805 and the second damping shaft 1807. The sliding seat 10 is sleeved and connected to the transverse frame 901, and the sliding seat 10 is welded and fixed to the sleeve frame 12.

[0030] The specific operation is as follows: by rotating the rolling wheel 4, the displacement seat 3 can be driven to slide on the track 2 at the top of the elevated platform 1, and the displacement seat 3 can drive the cross bar assembly 8 to move synchronously during the sliding process, so that the cross bar assembly 8 can drive the lifting assembly 18 to move to the same straight line as the required lifting object, and through the operation of the driving wheel 902 inside the transverse frame 901, the transverse frame 901 can be driven to move horizontally on the surface of the rod body 801, so that the lifting assembly 18 can move to the top of the object to be lifted. At this time, after the staff has hooked the goods to be lifted with the hook 1804, the lifting box 1801 is used to drive the lifting chain 1802 to rewind, so that the equipment can lift the goods. After the equipment completes the lifting of the goods , through the displacement of the rolling wheel 4 on the track 2 and the displacement of the transverse frame 901 on the rod body 801, the equipment can realize the transportation of the lifted goods. In the process of the equipment carrying the goods, the hydraulic cylinder 5 works to drive the lifting seat 6 to move up and down, and the lifting seat 6 can make the rod body 801 appear inclined through the rotation of the rotating shaft 7 during the lifting process, and the equipment can make the inclined surface face the direction according to the transportation direction of the goods. By making the rod body 801 inclined and then trying to displace the driving wheel 902, the movement resistance of the driving wheel 902 can be greatly reduced, which can effectively improve the convenience of the equipment for carrying goods. In addition, when the equipment is in the process of carrying goods, if there are staff passing by on the route of the goods, the first electric push rod 80 3 works, can drive the displacement plate 804 to move, so that the displacement plate 804 can drive the engaging tooth 805 at its outer end to move closer to the rack 903 on the inner side of the transverse frame 901, so that the engaging tooth 805 can mesh with the rack 903, and when the engaging tooth 805 meshes with the rack 903, the transverse displacement of the transverse frame 901 can be locked suddenly, which avoids the situation that the driving wheel 902 stops working, but the transverse frame 901 continues to move due to inertia and collides with the staff on the route, which can effectively improve the safety of the equipment. In addition, during the process of the transverse frame 901 being locked suddenly, the second electric push rod 11 works to drive the sliding seat 10 to move laterally in the opposite direction of the transverse frame 901, so that the sliding seat 10 can drive its bottom end The sleeve frame 12, the lower pressure seat 13 and the lifting assembly 18 are moved in the direction opposite to the movement direction. By moving the sleeve frame 12, the lower pressure seat 13 and the lifting assembly 18 in the direction opposite to the movement direction, the goods transported by the lifting assembly 18 can be prevented from being displaced toward the direction of the staff due to inertia during the emergency stop and colliding with the staff. In addition, the lifting box 1801 and the connecting plate 1803 are connected by the first damping shaft 1805, the damping telescopic rod 1806 and the second damping shaft 1807. The first damping shaft 1805, the damping telescopic rod 1806 and the second damping shaft 1807 can be rotated and extended to ensure that the connecting plate 1803 is always connected with the lifting box 1801 during the lifting process.Thanks to the high damping of the first damping shaft 1805, the damping telescopic rod 1806 and the second damping shaft 1807, it can effectively ensure that the goods will not shake frequently due to the lifting state during the process of the equipment lifting the goods, which can further improve the transportation stability of the equipment. In addition, after the goods are lifted on the hook 1804, the weight of the goods will produce a downward pulling force on the lifting box 1801, and the lifting box 1801 is fixed to the lower pressure seat 13. When the lifting box 1801 is subjected to the downward pulling force, it can drive the lower pressure seat 13 to squeeze the pressure spring 14 and move downward together. If the goods lifted on the hook 1804 are too heavy, the lower pressure seat 13 will move down to the fixed frame 15 due to the excessive downward pulling force, and contact with the pressure sensor 17. When the sensor 17 senses pressure, it means that the cargo lifted on the surface hook 1804 is too heavy, which allows the staff to quickly determine whether the cargo is too heavy during the lifting process, thereby avoiding damage to the equipment due to the overweight cargo. In addition, by twisting the wire lever 16, the wire lever 16 can be raised and lowered in the fixed frame 15, and the wire lever 16 can drive the pressure sensor 17 to adjust the height during the lifting process, so that the equipment can adjust different overweight benchmarks according to the different lifting cargoes, which improves the flexibility of the equipment. In addition, the pressure spring 14 can play a shock-absorbing role in the process of moving the cargo, reducing the vibration transmitted to the cargo during the movement of the rolling wheel 4 and the transverse frame 901, which further improves the mobile stability of the equipment.

[0031] In summary, when the overhead mobile crane is used, the rolling wheel 4 is first rotated to drive the displacement seat 3 to slide on the track 2 at the top of the elevated platform 1, and the displacement seat 3 can drive the crossbar assembly 8 to move synchronously during the sliding process, so that the crossbar assembly 8 can drive the lifting assembly 18 to move to the same straight line as the required lifting object, and the driving wheel 902 inside the transverse frame 901 can drive the transverse frame 901 to move horizontally on the surface of the rod body 801, so that the lifting assembly 18 can move to the top of the object required to be lifted. At this time, after the staff has finished hooking the goods to be lifted and lifted with the hook 1804, the lifting box 1801 works to drive the lifting chain 1802 to rewind, so that the equipment can lift the goods;

[0032] Then, after the equipment has completed lifting the goods, the equipment can carry the lifted goods by moving the rolling wheel 4 on the track 2 and the transverse frame 901 on the rod body 801. In the process of carrying the goods, the equipment can drive the lifting seat 6 to move up and down through the operation of the hydraulic cylinder 5. During the lifting process, the lifting seat 6 can make the rod body 801 tilted by the rotation of the rotating shaft 7. The equipment can make the inclined surface face the direction according to the carrying direction of the goods. By making the rod body 801 tilted and then trying to move the driving wheel 902, the movement resistance of the driving wheel 902 can be greatly reduced, which can effectively improve the convenience of the equipment in carrying goods. In addition, when the equipment is in the process of transporting goods, if a worker passes by on the route of the goods, the first electric push rod 803 works to drive the displacement plate 804 to move, so that the displacement plate 804 can drive the engaging teeth 805 at its outer end to move closer to the rack 903 on the inner side of the transverse frame 901, so that the engaging teeth 805 can mesh with the rack 903, and when the engaging teeth 805 mesh with the rack 903, the transverse displacement of the transverse frame 901 can be locked suddenly, which avoids the situation that the driving wheel 902 stops working, but the transverse frame 901 continues to move due to inertia and collides with the workers on the route, which can effectively improve the safety of the equipment;

[0033] Then, during the process of the sudden locking of the transverse moving frame 901, the second electric push rod 11 works to drive the sliding seat 10 to move laterally in the opposite direction of the transverse moving frame 901, so that the sliding seat 10 can drive the sleeve frame 12, the lower pressure seat 13 and the lifting assembly 18 at its bottom to move in the direction opposite to the moving direction. By moving the sleeve frame 12, the lower pressure seat 13 and the lifting assembly 18 in the direction opposite to the moving direction, it can be prevented that the goods carried by the lifting assembly 18 are displaced toward the direction of the staff due to inertia during the emergency stop process and collide with the staff;

[0034] Subsequently, the lifting box 1801 is connected to the connecting plate 1803 via the first damping shaft 1805, the damping telescopic rod 1806 and the second damping shaft 1807. The first damping shaft 1805, the damping telescopic rod 1806 and the second damping shaft 1807 can rotate and retract to ensure that the connecting plate 1803 is always connected to the lifting box 1801 during the lifting process. Thanks to the high damping of the first damping shaft 1805, the damping telescopic rod 1806 and the second damping shaft 1807, it can effectively ensure that the goods will not shake frequently due to the hoisting state during the lifting process of the equipment, which further improves the transportation stability of the equipment.

[0035] Finally, after the cargo is hoisted on the hook 1804, the weight of the cargo will generate a downward pulling force on the lifting box 1801, and the lifting box 1801 is fixed to the lower pressure seat 13, so that when the lifting box 1801 is subjected to the downward pulling force, it can drive the lower pressure seat 13 to squeeze the pressure spring 14 and move downward together. If the cargo lifted on the hook 1804 is too heavy, the lower pressure seat 13 will move its bottom downward into the fixed frame 15 due to the excessive downward pulling force, and contact with the pressure sensor 17. When the pressure sensor 17 senses the pressure, it means that the cargo lifted on the hook 1804 is too heavy, which makes the staff in the process of lifting the cargo. It can quickly determine whether the cargo is too heavy, thereby avoiding damage to the equipment due to excessive cargo. In addition, by twisting the wire lever 16, the wire lever 16 can be raised and lowered in the fixed frame 15, and the wire lever 16 can drive the pressure sensor 17 to adjust the height during the lifting process, which allows the equipment to adjust different overweight standards according to different hoisted cargoes, thereby improving the flexibility of the equipment. In addition, the pressure spring 14 can play a shock-absorbing role in the process of moving the cargo, reducing the vibration transmitted to the cargo during the movement of the rolling wheel 4 and the transverse frame 901, which further improves the mobile stability performance of the equipment.
