Description

Technical Field

[0001] This utility model relates to the technical field of coal mining equipment, and in particular to a tracked electric self-propelled tail section. Background Technology

[0002] Existing retractable belt conveyor tail sections in coal mines are mainly divided into two categories: mechanical and hydraulic. Mechanical tail sections have a simple structure but are immovable, making them suitable only for light-duty operations. Hydraulic tail sections, while capable of supporting heavy equipment, suffer from poor mobility and are prone to oil leaks and high maintenance costs. Furthermore, the traditional tail section's adjustment and lateral movement functions typically rely on complex mechanical structures or manual operation, resulting in low automation and difficulty in adapting to the frequent position adjustments required during tunnel excavation, thus limiting the efficiency of bulk material conveying. Utility Model Content

[0003] The main objective of this invention is to provide a tracked electric self-moving tail section to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A tracked electric self-propelled tail section includes a frame, a tracked chassis at the bottom of the frame, and track assemblies on both sides of the tracked chassis. Lifting components are symmetrically arranged on both sides of the bottom of the frame, a material conveying assembly is located above the frame, and a lateral adjustment assembly is located below the material conveying assembly. The lateral adjustment assembly includes a slide rail sleeve seat, a slide rail beam, a lead screw, and a servo motor. The slide rail sleeve seat is bolted to the bottom of the material conveying assembly, and the slide rail beam is installed inside the slide rail sleeve seat, with horizontal threaded holes inside the slide rail beam. A servo motor is mounted on one side of the frame, and the output shaft of the servo motor is connected to a lead screw, which is threadedly connected to the slide rail beam.

[0006] Furthermore, the material conveying assembly includes a buffer idler group and a secondary conveyor belt guide rail. The buffer idler group is centrally located on the frame, and a conveyor belt for conveying materials is located above the buffer idler group. Secondary conveyor belt guide rails are located on both sides of the buffer idler group.

[0007] Furthermore, the frame is equipped with a track drive motor that is connected to the track assembly for transmission.

[0008] Furthermore, the lifting assembly is an electric telescopic rod, and the lifting assembly is set vertically downward.

[0009] This utility model also includes other components that enable the tracked electric self-propelled tail section to function normally, and these devices or components all employ conventional techniques in the art. Furthermore, devices and components not limited in this utility model all employ conventional techniques in the art, such as the track drive motor and servo motor mentioned in this application. In specific implementation, appropriate device or component models can be selected according to the specific working scenario.

[0010] The working principle of this invention is as follows: When the lifting assembly retracts, the servo motor drives the lead screw and the slide beam via threaded transmission, causing the material conveying assembly to move left and right as a whole, thus achieving the belt alignment function. When the entire machine needs to be moved laterally, the lifting assembly extends to the set stroke, pushing the track assembly away from the support surface. At this time, the servo motor drives the material conveying assembly to move laterally. After losing ground support, the track assembly will move in the opposite direction relative to the material conveying assembly. By controlling the forward and reverse rotation of the servo motor, precise lateral movement of the track assembly can be achieved, completing the equipment position adjustment operation.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. Improved mobility: The tracked electric self-propelled tail section adopts an electric drive DC system, combined with an electric telescopic rod and track assembly, which can realize the rapid movement and precise lateral movement of the equipment in the roadway, solving the problems of inconvenient movement and poor flexibility of traditional tail sections;

[0013] 2. Simple structure and automated upgrade: The lateral shifting function is realized through the screw transmission mechanism driven by the servo motor, which replaces the traditional complex mechanical or hydraulic structure, simplifies the equipment construction, significantly improves the level of automation, reduces the failure rate and reduces the amount of maintenance work.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] Example:

[0021] like Figures 1-4 As shown, a tracked electric self-propelled tail section includes a frame 1, a tracked chassis 2 at the bottom of the frame 1, and track assemblies 3 on both sides of the tracked chassis 2. Lifting components 5 are symmetrically arranged on both sides of the bottom of the frame 1. A material conveying component is located above the frame 1, and a lateral adjustment component 8 is located below the material conveying component. The lateral adjustment component 8 includes a slide rail sleeve seat 81, a slide rail beam 82, a lead screw 83, and a servo motor 84. The slide rail sleeve seat 81 is fixed to the bottom of the material conveying component by bolts. The slide rail beam 82 is installed inside the slide rail sleeve seat 81, and the slide rail beam 82 has horizontal screw holes. The servo motor 84 is installed on one side of the frame 1. The output shaft of the servo motor 84 is connected to the lead screw 83, and the lead screw 83 is threadedly connected to the slide rail beam 82.

[0022] Specifically, the material conveying assembly includes a buffer idler group 6 and a secondary conveyor belt guide rail 7. The buffer idler group 6 is centrally located on the frame 1, and a conveyor belt 9 for conveying materials is located above the buffer idler group 6. The secondary conveyor belt guide rail 7 is located on both sides of the buffer idler group 6.

[0023] The lifting assembly 5 is an electric telescopic mast, and it is vertically downward. The lifting stroke of the electric telescopic mast is 200mm. The frame 1 is equipped with a track drive motor 4, which is connected to the track assembly 3. The track drive motor 4 is a DC motor.

[0024] The working principle of this utility model of a tracked electric self-propelled tail section is as follows: When the lifting component 5 retracts, the servo motor 84 drives the screw 83 and the slide beam 82 through threaded transmission, causing the material conveying component to move left and right as a whole, thus realizing the adjustment function of the conveyor belt 9. When it is necessary to move the entire machine laterally, the lifting component 5 extends to the set stroke, pushing the track assembly 3 away from the support surface. At this time, the servo motor 84 drives the material conveying component to move laterally. After losing ground support, the track assembly 3 will generate a reverse displacement relative to the material conveying component. By controlling the forward and reverse rotation of the servo motor 84, the precise lateral movement of the track assembly 3 can be achieved, completing the position adjustment operation of the equipment.

[0025] The above embodiments are merely descriptions of preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope of the present utility model.
