Description

Technical Field

[0001] This utility model relates to the field of crane beam technology, specifically a crane beam for use in cranes. Background Technology

[0002] The crane beam is the core load-bearing component of the crane system, directly supporting the operation and load of the crane. It is usually installed on the supporting structure (such as columns or brackets) of the factory or open-air structure to provide a moving track for the crane trolley or electric hoist.

[0003] The prior art patent document CN218968671U provides a crane beam for a double-girder crane, including a main beam body, a load-bearing block extending from the end of the main beam body, a load-bearing groove fitted to the outer side of the load-bearing block, a positioning member extending from the rear end of the load-bearing groove, the rear end of the load-bearing block located inside the positioning member, a beam seat extending from the lower end of the load-bearing groove, a fixing frame extending from the upper end face of the load-bearing groove near the front edge, a threaded column rotatably mounted through the upper end face of the fixing frame, a corner block screwed onto the outer side of the threaded column, the corner block penetrating the upper end face of the load-bearing groove, the inner wall of the corner block fitting against the outer surface of the load-bearing block, and a directional member provided between the corner block and the fixing frame. This utility model facilitates assembly and improves safety during use.

[0004] Although the device has many beneficial effects, it still has the following problems: If the main body of the load-bearing beam is damaged during use, the load-bearing beam needs to be replaced to prevent safety accidents. Since the load-bearing beam is mostly a whole, the entire beam needs to be replaced, which is costly and inconvenient. At the same time, when the device drives the equipment to perform the lifting operation, the moving block needs to maintain a relatively sensitive sliding effect. If the moving block is forcibly driven to move under a large friction force, it may shorten the service life of the moving beam and result in poor lubrication. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] 1. Technical problems to be solved:

[0007] To address the aforementioned issues, if the main body of the load-bearing beam is damaged during use, it is necessary to replace the entire load-bearing beam to prevent safety accidents. Since the load-bearing beam is usually a single unit, replacement requires replacing the entire beam, which is costly and inconvenient. Furthermore, when the device drives the equipment for lifting operations, the moving block needs to maintain a highly sensitive sliding effect. Forcing the moving block to move under high friction may shorten the lifespan of the moving beam and result in poor lubrication.

[0008] Therefore, the purpose of this utility model is to provide a crane beam for cranes. By installing the device in sections for the load-bearing beam, when a section of the load-bearing beam is damaged or unusable, a new load-bearing beam can be installed, saving costs and eliminating the need to remove the entire load-bearing beam during disassembly. At the same time, when the device is in operation, by starting the water pump, the water pump draws lubricating oil from the oil tank and drips it onto the surface of the load-bearing beam through the drainage pipe and nozzle, which can reduce the friction between the moving block and the load-bearing beam, extend the service life of the device, and reduce the possibility of jamming between the load-bearing beam and the moving block.

[0009] 2. Technical Solution:

[0010] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0013] As a preferred embodiment of the crane beam for a crane according to this utility model, a lead screw motor is fixedly connected to the side of the first fixed plate, and the output end of the lead screw motor is fixedly connected to the electric lead screw. The lead screw motor is electrically connected to an external distribution box through a connecting line. The lead screw motor drives the electric lead screw to rotate, thereby driving the moving beam to move, so that the lifting equipment can change the lifting position.

[0014] As a preferred embodiment of the crane beam for cranes according to this utility model, a second fixing plate is fixedly connected to the front and back of the side rod, and a guide plate is fixedly connected to the back of the second fixing plate. The guide plate can increase the wind resistance effect of the device and reduce the impact of wind load.

[0015] As a preferred embodiment of the crane beam for a crane according to this utility model, the movable block has a groove inside, and the load-bearing beam is slidably connected inside the groove. The load-bearing beam connected by the groove allows the movable block to move along the direction of the load-bearing beam, thus achieving a directional effect for the load-bearing beam.

[0016] As a preferred embodiment of the crane beam for a crane according to this utility model, the bottom of the side rod is fixedly connected to a main load-bearing rod, and the side of the main load-bearing rod is fixedly connected to a support rod. By fixing the support rod to the side of the main load-bearing rod, the stability of the device can be further enhanced, so that the vibration emitted during operation is less likely to affect the stability of the device.

[0017] In a preferred embodiment of the crane beam for a crane according to the present invention, one end of the support rod is fixedly connected to the load-bearing beam, and the back of the load-bearing beam is fixedly connected to the guide plate.

[0018] 3. Beneficial effects:

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This type of crane beam for cranes: By assembling the load-bearing beam of the device into sections, and connecting the two sections of load-bearing beams together with the combination plate, connecting plate and reinforcing plate, and reinforcing bolts and double-headed bolts, when the load-bearing beam is damaged on the outside, the damaged section can be directly removed and replaced with a new load-bearing beam, without having to replace the entire load-bearing beam, saving costs and making disassembly more convenient.

[0021] This type of crane beam for cranes: An oil tank is connected to the top of the moving block. A water pump is activated via a control panel to draw lubricating oil from the tank, controlling the pump's output and delivering the oil to a drain pipe. The oil then drips from a nozzle with a set output volume onto the top of the load-bearing beam. When the moving block passes over the oiled section, it becomes coated with lubricating oil, reducing friction between the moving block and the load-bearing beam. This prevents uneven contact surfaces from causing jamming or jamming during operation, and provides long-term lubrication, extending the service life of both the moving and load-bearing beams.

[0044] Combination Figures 1-6 The crane beam used in this embodiment is used in the following specific way:

[0045] 1. When using this type of crane beam for cranes, first fill the oil tank 19 with lubricating oil. After filling the oil tank 19 with lubricating oil, determine the approximate number of load-bearing beams 13 needed. After determining the number of load-bearing beams 13 required, you can begin assembling the load-bearing beams 13. First, insert the assembly plate 15 into the assembly groove 14 opened on the side of the load-bearing beam 13. As you continue to insert it inward, the holes inside the connecting plate 25 will automatically align with the holes opened at the top and bottom of the load-bearing beam 13. At this point, insert the double-ended bolts 18 and tighten them. Then... Take out the reinforcing plate 16, align the two holes on the left side of the reinforcing plate 16 with the two holes in the middle vertical plate of the load-bearing beam 13 on the left side, and then align the two holes on the right side of the reinforcing plate 16 with the two holes in the middle vertical plate of the load-bearing beam 13 on the right side. Repeat the above operation on the reinforcing plate 16 on the back. After aligning the holes, insert the reinforcing bolts 17 into the aligned holes and tighten the reinforcing bolts 17 to splice the two load-bearing beams 13 together. Then, install the spliced ​​load-bearing beams 13 on the side of the side bar 3 with bolts. The splicing is relatively convenient.

[0046] 2: During the use of this device, the water pump 22 and the lead screw motor 7 are started through the control panel. The lead screw motor 7 drives the electric lead screw 8 to rotate, thereby moving the moving beam 9. Movable blocks 10 are fixedly connected to both sides of the moving beam 9, so that the moving beam 9 can move the movable blocks 10 together. At the same time, a sliding groove 12 is opened inside the movable block 10. The sliding groove 12 is partially connected to the top of the load-bearing beam 13 through the sliding groove 12, which strengthens the stress point of the device. After the water pump 22 is started, the water pump 22 will draw lubricating oil from the oil tank 19 and deliver it to the drainage pipe 23. Then, the oil spray nozzle 24 is set at the bottom of the drainage pipe 23 to drip the lubricating oil onto the top of the load-bearing beam 13, thereby preventing the movable block 10 and the load-bearing beam 13 from jamming each other and extending the service life of the device.

[0047] 3: When the device is in operation, the screw motor 7 and water pump 22 will vibrate. A support rod 2 is fixedly connected to the side of the main load-bearing rod 1. The support rod 2, the load-bearing beam 13 and the main load-bearing rod 1 form a triangular structure. The high stability of the triangle reduces the impact of the vibration generated by the screw motor 7 and water pump 22 during operation. At the same time, a second fixing plate 6 is fixedly connected to the front of the load-bearing beam 13 and the side rod 3. A guide plate 5 is fixedly connected to the top of the second fixing plate 6. The guide plate 5 can make the device resistant to wind disturbance and reduce the impact of wind load on the device.
