Description

Technical Field

[0001] This utility model relates to the technical field of monorail crane supporting equipment, specifically a rope winding device for a mining pneumatic monorail crane. Background Technology

[0002] In underground coal mine transportation systems, pneumatic monorail cranes have become an important component of modern automated coal mine transportation due to their advantages such as strong adaptability to complex environments, high safety, high maneuverability, and good economy. Compared with traditional rail locomotives and wire rope traction equipment, pneumatic monorail cranes can efficiently complete the lifting and transportation of materials and equipment, and are especially suitable for narrow, winding, or gradient-changing tunnel environments.

[0003] However, pneumatic monorail cranes rely on a continuous supply of high-pressure gas for power, typically requiring a connection to a fixed-mounted air compressor via pneumatic pipelines. In existing technology, these pneumatic pipelines are generally laid directly on the tunnel floor, and the monorail crane's movement is coordinated with manual dragging and retraction. This method presents the following significant problems:

[0004] 1. Safety hazards: Manual operation makes it difficult to control the pipeline in and out in real time, which can easily cause the pipeline to scrape against equipment, supports or protrusions in the roadway, resulting in pipeline wear, rupture or even high-pressure gas leakage, and causing safety accidents.

[0005] 2. Inefficiency: Manual intervention requires additional personnel, which not only increases labor costs but may also affect the continuous operation efficiency of the monorail crane due to operation delays.

[0006] 3. Space occupation: The messy pipelines occupy the ground space of the alley, hindering the passage of personnel and the placement of other equipment and materials, and deteriorating the working environment.

[0007] To address the aforementioned issues, existing technologies have attempted to use fixed guide wheels or simple reels to assist in the deployment and retraction of pipelines. However, these methods still cannot solve the dynamic matching problem when the pipeline moves synchronously with the monorail crane. Especially when traveling long distances and in multiple directions, there is still a risk of pipeline accumulation, entanglement, or overload due to stretching. Utility Model Content

[0008] In view of the above-mentioned shortcomings in the existing technology, the purpose of this utility model is to provide a rope winding device for a mining pneumatic monorail crane, which effectively solves the pain points of pipeline management of traditional pneumatic monorail cranes, improves the safety, reliability and operation efficiency of coal mine transportation, and has significant economic benefits and application value.

[0009] The technical solution adopted by this utility model to achieve the above objectives is: a rope winding device for a mining pneumatic monorail crane, comprising an assembly bracket, a rope winding wheel, a pipeline connection assembly, and a drive assembly. The assembly bracket is hung on a single-row traveling guide rail and connected to the monorail crane. The monorail crane is assembled on the traveling guide rail and drives the assembly bracket to move synchronously along the traveling guide rail. The drive assembly is installed on the assembly bracket and maintains a power connection with the rope winding wheel.

[0010] An assembly shaft is fixedly connected to the axis of the rope winding wheel and rotatably mounted on the assembly bracket. The pipeline connection assembly includes a connecting pipe, a connecting tube, and a pressure plate. The connecting pipe and the connecting tube are respectively fixed to both sides of the pressure plate and maintain communication. The pressure plate is fixedly mounted on the assembly bracket. One end of the assembly shaft has an axial through hole and a radial through hole that maintain communication. The connecting pipe is rotatably mounted in the axial through hole and maintains communication with the axial through hole. The connecting tube is connected to the power unit of the monorail crane. A pneumatic pipeline is wound on the rope winding wheel. The inner end of the pneumatic pipeline is connected to the radial through hole, and the outer end of the pneumatic pipeline is released from the rope winding wheel and connected to a high-pressure air source.

[0011] Based on the above technical solutions, in order to ensure the structural strength of the assembly bracket and to achieve stable assembly and operation of the rope wheel on it, the following technical solutions are provided.

[0012] The assembly bracket includes a mounting top frame, a connecting frame, and an assembly plate. The mounting top frame is fixedly connected to both sides of its bottom. The bottom of the connecting frame is fixedly connected to the assembly plate. An assembly sleeve is fixedly connected to the assembly plate. The assembly shaft is rotatably installed into the assembly sleeve. The pressure plate is fixedly installed to the outer end of one of the assembly sleeves.

[0013] Based on the above technical solutions, in order to ensure the stable erection of the assembly bracket on the travel guide rail and to realize the connection and combination of the assembly bracket and the monorail crane, the following technical solutions are provided.

[0014] It also includes a support assembly, which includes a mounting frame, an upper support wheel, and a lower support wheel. Both sides of the mounting top frame are fixedly connected to lugs. A connecting seat is fixedly connected to the mounting frame. The connecting seat is hinged to the lugs. The upper support wheel and the lower support wheel are rotatably mounted in the mounting frame and are both in contact with the travel guide rail.

[0015] Based on the above technical solutions, in order to ensure that the drive component can be stably installed and achieve power connection with the winding wheel, the following technical solutions are provided.

[0016] One set of the connecting frames is fixedly connected to a mounting pad, and two sets of positioning plates are fixedly installed on the mounting pad; the drive assembly includes a pneumatic motor, a drive sprocket, and a transmission sprocket. The pneumatic motor is fixedly installed between the two sets of positioning plates, the drive sprocket is fixedly installed on the output shaft of the pneumatic motor, and the transmission sprocket is fixedly connected to the assembly shaft. The drive sprocket and the transmission sprocket are driven by a chain.

[0017] Based on the above technical solutions, in order to ensure that the winding wheel can be stably assembled between the two sets of assembly plates and to ensure that the pneumatic pipeline is stably wound on it, the following technical solutions are provided.

[0018] The winding wheel includes a pad, an axial rod, a radial rod, and a wheel rim. Two sets of pads are fixedly connected to the assembly shaft. The pads are grounded to the inner end of the assembly sleeve. The axial rod and the radial rod are both fixedly connected to the outer edge of the two sets of pads and are arranged in a ring array. The wheel rim is fixedly connected to the outer end of the radial rod.

[0019] The beneficial effects of this utility model are:

[0020] 1. Automated retraction and extension enhance safety. Through the cooperation of the drive component and the rope winding wheel, the pneumatic pipeline is automatically retracted and extended, avoiding pipeline scratches and breaks caused by delays or errors in manual operation. This reduces the risk of high-pressure gas leakage and ensures the safety of underground coal mine operations. The rope winding device operates in conjunction with the monorail crane to ensure that the retraction and extension length of the pneumatic pipeline is precisely matched with the crane's travel distance, preventing pipeline accumulation, excessive stretching or dragging, and reducing the probability of equipment damage.

[0021] 2. The structure is stable and the operation is reliable. The assembly bracket adopts a square tube welded structure, which, together with the support group, ensures that the device remains stable during the movement of the monorail crane, avoids shaking or deviation, and improves the overall structural strength and service life. The winding wheel adopts a combination structure of axial and radial rods, which can not only ensure the orderly winding of the pneumatic pipeline, but also prevent the pipeline from falling off or getting stuck, ensuring a smooth winding and unwinding process.

[0022] 3. Stable air circuit connection and efficient power transmission: The axial and radial through holes of the pipeline connection components and the assembly shaft ensure stable delivery of high-pressure gas during rotation, avoiding the twisting and leakage problems that are common with traditional hose connections. The pneumatic motor and the monorail crane share the same high-pressure air source, requiring no additional power and achieving energy efficiency.

[0023] 4. Optimizes tunnel space and improves operational efficiency. Pneumatic pipelines are automatically extended and retracted via rope reels, avoiding messy laying on the ground, reducing interference with personnel passage and other equipment placement, and improving tunnel space utilization. It also reduces manual intervention, lowers labor intensity, and improves the continuous operation efficiency of the monorail crane, making it suitable for transportation needs in long-distance, complex tunnels.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-5 A rope winding device for a mining pneumatic monorail crane includes an assembly bracket 1, a rope winding wheel 2, a pipeline connection assembly 3, and a drive assembly 4. The assembly bracket 1 is hung on a single-row traveling guide rail 6 and connected to the monorail crane. The monorail crane is assembled on the traveling guide rail 6 and drives the assembly bracket 1 to move synchronously along the traveling guide rail 6. The drive assembly 4 is installed on the assembly bracket 1 and maintains a power connection with the rope winding wheel 2.

[0032] An assembly shaft 21 is fixedly connected to the axis of the rope winding wheel 2 and rotatably mounted on the assembly bracket 1. The pipeline connection assembly 3 includes a connecting pipe 31, a connecting pipe 32, and a pressure plate 33. The connecting pipe 31 and the connecting pipe 32 are fixedly connected to both sides of the pressure plate 33 and maintain communication. The pressure plate 33 is fixedly mounted on the assembly bracket 1. One end of the assembly shaft 21 is provided with an axial through hole 211 and a radial through hole 212 to maintain communication. The connecting pipe 31 is rotatably mounted in the axial through hole 211 and maintains communication with the axial through hole 211. The connecting pipe 32 is connected to the power unit of the monorail crane. A pneumatic pipeline 7 is wound on the rope winding wheel 2. The inner end of the pneumatic pipeline 7 is connected to the radial through hole 212. The outer end of the pneumatic pipeline 7 is released from the rope winding wheel 2 and connected to a high-pressure air source.

[0033] The mounting bracket 1 enables stable assembly on the travel guide rail 6 and connection with the monorail crane, while ensuring the stable assembly and operation of the rope wheel 2, pipeline connection assembly 3, and drive assembly 4 on it.

[0034] Since the rope winding device moves synchronously with the monorail crane, the pipeline used to connect the power unit and the connecting pipe 32 is not affected by the travel posture of the monorail crane, ensuring that high-pressure gas can be stably delivered to the power unit of the monorail crane, thereby driving the relevant equipment to operate stably, so as to realize the stable travel of the monorail crane along the travel guide rail 6.

[0035] The high-pressure gas source is provided by equipment such as an air compressor. Since the air compressor is installed in a fixed manner, the pneumatic pipeline 7 of the high-pressure gas source needs to be connected to the air compressor. During the movement of the monorail crane and the winding device, the pneumatic pipeline 7 can be adjusted in real time by the running winding wheel 2.

[0036] When the drive component 4 is running, it can drive the rope wheel 2 to operate stably, so that the pneumatic pipeline 7 wound on it can be adjusted in terms of extension and retraction. When the monorail crane travels a certain distance, the rope wheel 2 is exactly retracted or extended to a certain length, so as to avoid the pneumatic pipeline 7 being dragged or scratched and damaged by other equipment. The stable extension and retraction adjustment of the pneumatic pipeline 7 can also avoid the pneumatic pipeline 7 from breaking or loosening of the interface, thereby improving the safety of equipment operation.

[0037] To ensure the structural strength of the mounting bracket 1 and to enable the rope wheel 2 to be stably assembled and operated on it, the following technical solution is provided.

[0038] The assembly bracket 1 includes a mounting top frame 11, a connecting frame 12, and an assembly plate 13.

The setting of the connecting frame 12 can ensure the stable installation of the assembly plate 13, thereby realizing the stable installation and operation of the rope wheel 2 on the assembly bracket 1 in a relatively rotating posture.

[0040] The pressure plate 33 is fixed to the end of the assembly sleeve 131 by bolts, thereby ensuring that the connecting pipe 31 and the connecting pipe 32 are always fixed to the assembly bracket 1. When the assembly shaft 21 at the center of the winding wheel 2 rotates, the connecting pipe 31 always remains connected to the axial through hole 211 and will not interfere with the movement, thereby ensuring the stable transmission of high pressure gas.

[0043] The lug 111 is hinged to the connecting seat 511 on the mounting frame 51 so that the support component 5 is arranged on both sides of the mounting top frame 11. It is stably erected and moves on the travel guide rail 6 through the upper support wheel 52 and the lower support wheel 53 provided on it. The connecting seat 511 on the other side of the mounting frame 51 can also be connected to the monorail crane. During the movement of the monorail crane, the rope winding device is driven to move synchronously through the support component 5.

[0044] The travel guide rail 6 is made of H-steel or I-beam. The upper support wheel 52 and the lower support wheel 53 are arranged on both sides of the web of the travel guide rail 6. The upper support wheel 52 and the lower support wheel 53 are respectively in contact with the upper and lower sides of the lower flange. When the monorail crane is running, the rope winding device can be driven to move by the stable operation of the upper support wheel 52 and the lower support wheel 53.

[0045] To ensure that the drive assembly 4 can be stably installed and achieve a power connection with the winding wheel 2, the following technical solution is provided.

Positioning plate 122 is set in L-shape and fixed to mounting pad 121 with bolts. Pneumatic motor 41 is also fixed to positioning plate 122 with bolts to achieve stable installation.

[0048] The air supply line led out from the connecting pipe 32 can be connected to the pneumatic motor 41 and the power unit of the monorail crane through the diversion valve. When the monorail crane is driven by high pressure gas, it can drive the pneumatic motor 41 to run, and then drive the assembly shaft 21 and the rope wheel 2 to run stably through the combination of the drive sprocket 42 and the transmission sprocket 43.

[0049] To ensure that the winding wheel 2 can be stably assembled between the two sets of assembly plates 13 and that the pneumatic pipeline 7 can be stably wound on it, the following technical solution is provided.

[0050] The winding wheel 2 includes a pad 22, an axial member 23, a radial member 24, and a wheel rim 25. Two sets of pads 22 are fixedly connected to the assembly shaft 21.
