Description

Technical Field

[0001] The utility model relates to the field of engineering machinery, in particular to a rope supporting device with a rope returning device which can be efficiently disassembled and assembled, and a crawler crane. Background Art

[0002] As the primary connecting component between components, wire ropes inevitably come into contact and rub against adjacent components during operation. Frequent friction can cause wire rope wear and even breakage, while also causing varying degrees of wear to components in contact with the wire rope. Therefore, a rope support device is needed to prevent frictional wear between the wire rope and other components.

[0003] In addition, when the crawler crane is working, the wire rope may easily escape from the protection range of the rope support device due to the vibration of the wire rope. In the prior art, the rope support device is mainly divided into two types: one is the traditional rope support device, such as Figure 1 and Figure 2 As shown, the rope supporting device structures in the two figures are both traditional structures that only have a supporting function, and both have the problem that the wire rope cannot return after popping out of the rope supporting device.

[0004] In order to solve the above problems, existing technologies such as Figure 3 and Figure 4 As shown, rope return devices are designed on both sides of the rope supporting device, and the wire rope can return to the protection range of the rope supporting device through the slope.

[0005] but, Figure 3 The solution has the problem of not being able to effectively prevent the wire rope from slipping out of the rope supporting device;

[0006] Figure 4 The rope supporting device of the solution has problems of poor rigidity and easy deformation due to the roller being suspended in the air.

[0007] Furthermore, when the rope return device is welded to a component that has frictional contact with the wire rope, it cannot be disassembled. When customers need to transport related components to another location, they often stack them to save costs. This can easily cause welded rope return devices to deform and become damaged due to stacking, increasing operating and maintenance costs.

[0008] However, when the rope return device is fixed to a component in frictional contact with the wire rope through a bayonet assembly, the rope return device is mainly fixed by the friction force at the bayonet. This fixing method has poor reliability and the rope return device is prone to translation along the component, resulting in a gap between the bent plate rope return device and the rope supporting device. At this time, the wire rope is easily stuck in the gap when sliding out or sliding back into the rope supporting device. If not discovered in time, the wire rope may even be damaged or broken, which not only poses a huge safety risk but also increases the customer's maintenance and operating costs.

[0009] Therefore, a safe, reliable and detachable rope supporting device is urgently needed to solve the above problems. Summary of the Invention

[0010] In response to the above problems, the present invention provides a rope-supporting device that can effectively prevent the wire rope from detaching and can smoothly return the detached wire rope to its original position. The specific solution is as follows:

[0011] A rope supporting device with an efficiently detachable rope return device, the rope supporting device including a flexible pad, the flexible pad being arranged on a contact surface to avoid frictional contact between a steel wire rope and the contact surface, rope return structures being provided on both sides of the flexible pad, the rope return structures including a baffle abutting against a side edge of the flexible pad on one side, the height of the baffle being higher than the top surface of the flexible pad, the two baffles and the flexible pad forming a "concave" structure, the other side of the baffle being provided with a slope connected to its top, the slope forming an angle greater than 90° with the contact surface.

[0012] Furthermore, the flexible pad is made of nylon material.

[0013] Furthermore, a cutout is provided on the side of the flexible pad, a cutting plate is provided on the side of the baffle for inserting into the cutout, and bolts are provided passing through the flexible pad, the cutting plate and the contact surface for fixing.

[0014] Furthermore, a bayonet is provided on the slope, a screw is inserted into the bayonet and fixed to the contact surface, and the screw is immersed in the bayonet.

[0015] Furthermore, the baffle, cutting plate and slope are integrally connected.

[0016] Furthermore, the connection between the slope and the top of the baffle is rounded.

[0017] Furthermore, a crawler crane is provided, on which the rope supporting device is installed.

[0018] Compared with the prior art, the advantages of the present invention are as follows:

[0019] 1. The utility model sets baffles on both sides of the flexible pad to prevent the wire rope from "bouncing" out of the range of the flexible pad, and makes the wire rope "bounce" back to the flexible pad along the slope through the slope.

[0020] 2. Compared with the rope-supporting device with a roller structure, the flexible pad of the present invention has the advantage of a low failure rate.

[0021] 3. The utility model has the advantage of tightly connecting the rope return structure with the flexible pad through the solution of "a cutout is provided on the side of the flexible pad, a cutting plate is provided on the side of the baffle to be inserted into the cutout, and bolts passing through the flexible pad, the cutting plate and the contact surface for fixing". This avoids the phenomenon of the wire rope being stuck in the gap due to the formation of a gap.

[0022] 4. The utility model fixes the slope and the contact surface to prevent the slope from rotating under force through the solution of "a bayonet is provided on the slope, a screw is inserted into the bayonet and fixed to the contact surface, and the screw is immersed in the bayonet".

[0023] 5. The rope supporting device of the utility model is easy to disassemble from the contact surface and is convenient for transportation. BRIEF DESCRIPTION OF THE DRAWINGS
