[0024] The utility model will be further described below in conjunction with the accompanying drawings.

[0025] The C80 coal mine special open wagon is a special open wagon designed and manufactured for the Daqin Line (Datong-Qinhuangdao) in my country. Its main function is to transport coal. It is also a heavy-duty wagon designed to increase the transportation volume of trucks. Among them, the open wagon is a bathtub funnel unloading structure.

[0026] When a C80 coal mine open wagon has a major derailment or other accident, it will cause damage to the bogie and the track, which generally needs to be handled by lifting and recovery operations. Since the C80 vehicle body is made of aluminum alloy and its side beam is a "groove-type" structure (such as Figure 3 As shown in the figure, the vehicle has many edges and corners, and the traditional magnetic corner protectors cannot be attached to the vehicle body. When the rail crane is used for lifting and recovering operations on site, the whole vehicle and one end are basically connected by the "big bag" (i.e., directly lifting with the lifting rope). The rope is easily cut during the lifting and recovering operation, causing secondary accidents or equipment damage.

[0027] In response to the above technical issues, such as Figure 1 , Figure 2 , Figure 3 As shown, the embodiment of the utility model provides a lifting rope anti-breaking device, comprising a cylindrical body 10, and a side surface of the cylindrical body 10 is provided with an inwardly concave arc-shaped rope groove 110 and a mounting groove 120;

[0028] The arc-shaped rope groove 110 extends along the circumferential direction of the cylindrical body 10, and the mounting groove extends into the cylindrical body 10 and penetrates the cylindrical body 10 in the length direction of the cylindrical body 10, wherein the extension depth of the mounting groove 120 is greater than the depth of the arc-shaped rope groove 110, and a preset distance is formed between the side wall of the mounting groove 120 and the arc surface of the arc-shaped rope groove 110.

[0029] It should be noted that the arc-shaped rope groove 110 can cover the entire circumference of the cylindrical body 10. By making the depth of the installation groove 120 greater than the depth of the arc-shaped rope groove 110, the installation groove 120 can extend into the area of ​​the cylindrical body 10 that is not covered by the arc-shaped rope groove 110. In this way, the contact area with the frame groove 20 can be increased when the installation groove 120 is nested on the frame groove 20, thereby increasing the force-bearing area. Figure 3 A preset distance between the bottom surface of the mounting groove 120 and the bottom surface of the arc-shaped rope groove 110 can ensure that there is a certain thickness of material between the mounting groove 120 and the arc-shaped rope groove 110 to ensure the strength of the device and avoid deformation during the lifting operation.

[0030] It should be noted that the depth of the arc-shaped rope groove 110 , the extension depth of the installation groove 120 and the preset distance can be set according to actual needs, that is, they can be set according to the size of the frame groove 20 and the size of the cylindrical body 10 .

[0031] In some embodiments, the installation groove 120 extends to a depth beyond a first centerline of the cylindrical body 10 , and the first centerline is perpendicular to the installation groove 120 .

[0032] In some embodiments, the mounting groove 120 is located below a second center line of the cylindrical body 10 , and the second center line is parallel to the mounting groove 120 .

[0033] It should be noted that if Figure 1 , Figure 3 As shown, the first center line is the vertical center line of the cylindrical body 10, so that the extension depth of the installation groove 120 exceeds the first center line. On the one hand, it can increase the contact area between the installation groove 120 and the frame groove 20. On the other hand, when the cylindrical body 10 is installed on the frame groove 20, the center of gravity of the cylindrical body 10 can be located in the frame groove 20, and there will be no tendency to tip over.

[0034] It should be noted that the second center line is the horizontal center line of the cylindrical body 10. Considering that during the lifting operation, the weight of the vehicle body (or equipment) acts on the cylindrical body 10 through the frame groove 20 and then acts on the lifting rope, it is necessary to make the top surface and side surfaces of the cylindrical body 10 abut against the side walls and top of the frame groove 20 in order to better transfer the weight of the vehicle body. If the installation groove 120 is located on the center line of the cylindrical body 10, then compared with being set on one side of the center line of the cylindrical body 10 (i.e., below the second center line), the diameter of the cylindrical body 10 needs to be larger. By locating the installation groove 120 below the second center line, the volume of the cylindrical body 10 can be reduced and the same force transmission effect can be achieved.

[0035] In some embodiments, a side abutment portion 130 is disposed on the cylindrical body 10 . The side abutment portion 130 is perpendicular to the mounting groove 120 and is in a planar shape and cuts off a portion of the arc-shaped rope groove 110 .

[0036] It should be noted that the side abutment portion 130 is planar and can abut against the side wall of the frame groove 20 to transmit force during the lifting operation. Usually, the side abutment portion 130 does not cut to the bottom of the arc-shaped rope groove 110 to ensure the integrity of the center force-bearing part of the cylindrical body 10.

[0037] In some embodiments, a weight-reducing hole 150 is provided on the cylindrical body 10 , and the weight-reducing hole 150 extends along the length direction of the cylindrical body 10 .

[0038] In some embodiments, the lightening hole 150 is located above the second center line, and the distance between the lightening hole 150 and the side abutment portion 130 is greater than the distance between the bottom surface of the mounting groove 120 and the side abutment portion 130 .

[0039] In some embodiments, transition slopes are provided between the weight-reducing holes 150 and the two end surfaces of the cylindrical body 10 .

[0040] It should be noted that the weight-reducing hole 150 is a through hole. By setting the weight-reducing hole 150, the weight of the cylindrical main body 10 can be reduced. The distance between the weight-reducing hole 150 and the side abutment portion 130 is greater than the distance between the bottom surface of the mounting groove 120 and the side abutment portion 130, that is, the weight-reducing hole 150 is located at the upper right of the mounting groove 120. Since the mounting groove 120 has been opened at the lower left of the cylindrical main body 10, arranging the weight-reducing hole 150 at the upper right of the cylindrical main body 10 can better ensure the structural strength of the cylindrical main body 10, wherein the area where the weight-reducing hole 150 is located is not covered by the arc-shaped rope groove 110.

[0041] It should be noted that by setting the transition slope, it is convenient to manually install and disassemble the lifting rope anti-breaking device. That is, when removing the lifting rope anti-breaking device, the finger can be inserted into the weight reduction hole 150 through the transition slope to conveniently remove the lifting rope anti-breaking device. The same is true when installing.

[0042] In some embodiments, a top surface abutment portion 140 is provided on the cylindrical body 10 , which is parallel to the mounting groove 120 and cuts off a portion of the arc-shaped rope groove 110 in a plane, wherein the top surface abutment portion 140 is located on a side of the cylindrical body 10 away from the mounting groove 120 .

[0043] It should be noted that since the top surface of the frame groove 20 is a plane, by providing the top surface abutting portion 140, it can better abut against the top surface of the frame groove 20 and better transfer the gravity of the vehicle body; the top surface abutting portion 140 is provided on the side of the cylindrical main body 10 away from the installation groove 120. On the one hand, it can ensure the strength of the cylindrical main body 10; on the other hand, it helps to reduce the volume of the cylindrical main body 10.

[0044] In some embodiments, a platform step 160 is respectively disposed at both ends of the arc-shaped rope groove 110 in the width direction, and a transition arc is disposed between the platform step 160 and the end surface of the arc-shaped rope groove 110 and the cylindrical body 10 .

[0045] In some embodiments, the cylindrical body 10 is integrally formed and is made of aluminum alloy.

[0046] It should be noted that by providing the platform step 160 and the transition arc, it can be ensured that the corners of the arc-shaped rope groove 110 will not cut off the lifting rope, thereby improving the lifting safety; by forming the cylindrical body 10 in one piece and using aluminum alloy material, the strength of the cylindrical body 10 can be ensured.

[0047] It should be noted that when using the hoisting rope anti-breaking device provided in this embodiment, the steps are as follows: 1) determine the installation position of the hoisting rope anti-breaking device; 2) install the hoisting rope anti-breaking device into the frame groove 20 of the above-mentioned installation position; 3) embed the hoisting rope into the arc-shaped rope groove 110, and confirm the embedding status of the hoisting rope at each position; 4) lift it by using the lifting device.

[0048] In summary, the advantages of the embodiments of the utility model are that, by providing an inwardly concave arc-shaped rope groove 110 and an installation groove 120 on the side of the cylindrical body 10; and making the arc-shaped rope groove 110 extend along the circumferential direction of the cylindrical body 10, the installation groove extends into the cylindrical body 10 and penetrates the cylindrical body 10 in the length direction of the cylindrical body 10, wherein the extension depth of the installation groove 120 is greater than the depth of the arc-shaped rope groove 110, and there is a preset distance between the side wall of the installation groove 120 and the arc-shaped surface of the arc-shaped rope groove 110, the hoisting rope anti-breaking device can be directly nested in the frame groove 20 of the vehicle or other equipment through the installation groove 120, and the hoisting rope is arranged on the arc-shaped groove, thereby avoiding the rope being cut off during the hoisting operation, causing secondary accidents and equipment damage.
