Description

Technical Field

[0001] This invention belongs to the field of damage prevention equipment technology, and in particular relates to a device for preventing breakage of towing cables for bucket wheel excavators. Background Technology

[0002] The power cable for the bucket wheel excavator consists of a 3*150mm cable. 2 The cable runs from underground to the surface and finally connects to the equipment. The cable needs to move left and right along the equipment's track. When the cable emerges from underground, it needs to be bent. If the bending angle is insufficient, the cable's own weight will cause excessive stress at the bend, damaging the cable and affecting its lifespan. A single 3*150mm cable... 2 The cost of one meter of tow cable is as high as 1400 yuan, and the tow cable of a typical mobile device is about 100 meters. Once damaged, the cost is not only as high as tens of thousands of yuan, but replacement also requires a lot of time, which has a significant impact on the operation of the existing coal conveying system. In the current technology, a rounded transition is used at the ground exit point to avoid excessive bending of the cable and damage. However, because mobile devices need to move frequently, the cable is turned back and forth, and stones, soil and other debris can get into the ground's curved depressions, filling them and causing the cable to be damaged due to excessive bending. Therefore, setting a certain rounded transition at the depressions does not achieve the desired effect. Summary of the Invention

[0003] The purpose of this invention is to provide a device to prevent damage to the towing cable of a bucket wheel excavator, so as to solve the technical problem that the cable is easily damaged due to movement and bending.

[0051] To better understand the purpose, structure, and function of this invention, the invention will be described in further detail below with reference to the accompanying drawings.

[0052] According to some embodiments of this application, including:

[0053] The mounting cavity 1 is located below the ground and has a through hole 101. That is, there is a cavity below the ground for accommodating the drag roller component 2, the cable, and the drive cable for conveying. Its shape and size are selected and set according to actual needs and are not limited here.

[0054] The cable-draft roller component 2 is disposed within the mounting cavity 1, and guides and limits the cable. It should be noted that the cable-draft roller component 2 is a modular structure, comprising:

[0055] The first arc-shaped component 201 is an arc-shaped plate structure. The first arc-shaped component 201 is disposed in the mounting cavity 1 and is fixedly connected to the side wall of the mounting cavity 1. That is, the first arc-shaped component 201 is fixed in the mounting cavity 1 by means of bolts, welding, riveting, etc.

[0056] The second arc-shaped component 202 is an arc-shaped plate structure. It is located within the mounting cavity 1, corresponding to the position of the first arc-shaped component 201. It is fixedly connected to the side wall of the mounting cavity 1, i.e., by bolts, welding, riveting, or other methods. The arc of the first arc-shaped component 201 and the second arc-shaped component 202 is the same; that is, an arc-shaped channel 20101 is formed between the first arc-shaped component 201 and the second arc-shaped component 202, with a first opening 201011 and a second opening 201012 at each end. The first opening 201011 of the arc-shaped channel 20101 corresponds to the position of the through hole 101 in the mounting cavity 1. In other words, the cable changes direction through the arc-shaped channel 20101 between the first arc-shaped component 201 and the second arc-shaped component 202, and the second arc-shaped component 202 constrains the cable, preventing excessive deformation.

[0057] The fixing component 203 is a tripod structure, located at the bottom of the mounting cavity 1, and is fixedly connected to the first arc-shaped component 201, providing support for the first arc-shaped component 201 and making it more stable. To ensure the stability of the second arc-shaped component 202, a fixing component 203 can also be added to support and fix the second arc-shaped component 202.

[0058] The vertical limiting component 204 is disposed in the mounting cavity 1, between the first opening 201011 and the through hole 101. The vertical limiting component 204 is a symmetrically arranged pressure plate structure, and there is a gap between two adjacent pressure plates. The cable passes through the gap between the two pressure plates, and then the pressure plates limit the cable to prevent it from undergoing irregular deformation.

[0059] A horizontal limiting component 205 is arranged in a matrix within the mounting cavity 1, located between the second opening 201012 and the cable driving component 4. The horizontal limiting component 205 is a pressure plate structure, arranged in a matrix on the side wall of the mounting cavity 1, which limits the cable located between the cable driving component 4 and the arc-shaped track 20101, keeping the cable in a horizontal state and preventing irregular deformation of the cable.

[0060] The number and distribution of the vertical limiting component 204 and the horizontal limiting component 205 are set and selected according to actual needs, and are not restricted here.

[0061] The ground anchor fixing component 3 is disposed on the ground and corresponds to the position of the through hole 101 in the mounting cavity 1. It should be noted that the ground anchor fixing component 3 is a modular structure, comprising:

[0062] Platform component 301 is located on the ground and has positioning holes 3011. The platform component 301 is fixedly connected to the ground. The platform component 301 has a plate-like structure and is 100-150mm higher than the ground to prevent external dust and impurities from entering the mounting cavity 1. It should also be noted that the positioning holes 3011 on the platform component 301 correspond to the through holes 101 in the mounting cavity 1, and the positioning holes 3011 are embedded in the through holes 101, further strengthening the strength of the through holes 101 on the ground.

[0063] An arc-shaped support component 302 is provided on the platform component 301 and has a central hole; the central hole corresponds to the positioning hole 3011.

[0064] The arc-shaped support component 302 can be either a symmetrical support rod structure or an integrated support frame structure, and there is no limitation on it.

[0065] When the arc-shaped support component 302 is a symmetrical support rod structure:

[0066] The arc-shaped support component 302 includes:

[0067] The first connecting component 3021 is a ring structure and is disposed on the platform component 301. It is fixedly connected to the platform component 301. That is, the first connecting component 3021 is a ring-shaped disk structure and its center is concentric with the positioning hole 3011 of the platform component 301. The platform component 301 is fixed to the platform component 301 by bolts, welding, riveting and other methods.

[0068] The support rod component 3022 is symmetrically arranged on the first connecting component 3021, located on both sides of the positioning hole 3011. The end of the support rod component 3022 is provided with an arc-shaped component 3023, that is, the support rod component 3022 is a fixed rod structure. One end of the support rod component 3022 is fixed to the first connecting component 3021 by means of bolts, welding, riveting, etc., and the other end of the support rod component 3023 is provided with an arc-shaped component 3023. The arc of the arc-shaped component 3023 is between 110-120°, preferably 110°. The arc-shaped component 3023 is used to support the cable that is bent above the ground.

[0069] The second connecting component is a connecting rod structure (not marked in the figure). The second connecting component is located between the two support rod components 3022, and its two ends are fixedly connected to the support rod components 3022 respectively, that is, fixed to the support rod components 3022 by means of bolts, welding, riveting, etc. It limits the cable and prevents the cable from falling out of the gap between the two support rod components 3022. It should be noted that the second connecting component can also adopt an arc plate structure.

[0070] When the arc-shaped support component 302 is an integral support frame structure, it includes:

[0071] The first connecting component 3021 is a ring structure and is disposed on the platform component 301. It is fixedly connected to the platform component 301. That is, the first connecting component 3021 is a ring-shaped disk structure and its center is concentric with the positioning hole 3011 of the platform component 301. The platform component 301 is fixed to the platform component 301 by bolts, welding, riveting and other methods.

[0072] An annular component 3024 is mounted on the first connecting component 3021 and is fixedly connected to it. The annular component 3024 has a central hole 30241 at its center, and an arc-shaped structure around the central hole 30241. The central hole 30241 corresponds to the positioning hole 3011 of the platform component 301. The annular component 3024 is a ring-shaped support frame structure with a central hole 30241 at its center, and the circumference of the central hole 30241 is an arc-shaped plate structure. In other words, the annular component 3024 has an arc-shaped central hole 30241 at its center, and after the cable passes through the central hole 30241, the annular component 3024 supports the cable bending above the ground.

[0073] To further optimize the above technical solution, a wear-resistant layer is coated on both the annular component 3024 and the arc-shaped component 3023, thereby improving the service life of the annular component 3024 and the arc-shaped component 3023.

[0074] A cable drive component 4 is disposed within the mounting cavity 1, and a cable is wound around it. It should be noted that the cable drive component 4 is a modular structure, comprising:

[0075] The motor component 401 is either a stepper motor or a servo motor, and the choice is made according to actual needs. No restriction is made here. The motor component 401 is located in the mounting cavity 1 and is fixedly connected to the mounting cavity 1.

[0076] The load component 402 is disposed within the mounting cavity 1 and has a rotating shaft on it. A wound cable is mounted on the load component 402. The rotating shaft is connected to the rotating end of the motor component 401 via a coupling 404. In other words, the load component 402 has a ring-shaped structure with a cable wound around it, and it rotates as driven by the motor component 401, thereby extending or retracting the cable.

[0077] The technical effects achieved by the above technical solution in the embodiments of this application are as follows:

[0078] The cable is wound around the load component 402, and the motor component 401 drives the load component 402 to rotate, thereby extending the cable. The extended cable passes through the horizontal limiting component 205 and enters the arc-shaped channel 20101 formed by the combination of the first arc-shaped component 201 and the second arc-shaped component 202. The cable exits through the arc-shaped channel 20101 and continues through the vertical limiting component 204, exiting from the through hole 101 of the mounting cavity 1. Finally, it passes through the arc-shaped support component 302 to connect with external equipment. The arc-shaped support component 302 supports and limits the cable bent above the ground, and the vertical limiting component 204, the horizontal limiting component 205, and the arc-shaped channel 20101 further limit the cable below the ground, preventing irregular deformation of the cable during movement. At the same time, it effectively supports the bent cable, preventing damage caused by excessive bending, effectively improving the overall stability of the equipment, and effectively preventing damage to the cable due to excessive bending.

[0079] In some embodiments of this application, the structure described in the above embodiments is adopted, and further includes: a torque detection component 403, which is disposed on the cable drive component 4;

[0080] Torque detection component 403 includes:

[0081] The torque sensing component has its input and output ends connected to the rotating end of the motor component 401 and the rotating shaft of the load component 402 respectively via a coupling 404. It is used to detect the torque of the cable in the current section and then convert the detected value into an electrical signal to be transmitted to the control component.

[0082] The control component is electrically connected to the torque sensing component. After receiving the detection data from the torque sensing component, when the detection data exceeds the threshold, the control component sends a command signal to the warning component to issue a warning. At the same time, the control component controls the motor component 401 to stop working and restarts it after checking that there are no problems.

[0083] The warning component is electrically connected to the control component and operates by receiving command signals from the control component. The warning component can provide warnings through sound and light to remind the user that the current torque is too high and to check and correct the current cable in a timely manner.

[0084] The technical effects achieved by the above technical solution in the embodiments of this application are as follows:

[0085] By adding a torque detection component 403 at the cable drive component 4, the torque of the cable is detected, preventing damage to the cable due to excessive torque. This further improves the overall stability of the equipment, effectively prevents damage to the cable due to excessive bending, and increases the service life of the cable, thereby effectively reducing production costs.
