Description

Technical Field

[0001] This application relates to the technical field of supporting mechanisms for coal coking cars, and in particular to a travel direction adjustment device for coal coking car recovery. Background Technology

[0002] Coke pushers are a common and fundamental facility in the coal refining industry. They move the coke pushing equipment to the corresponding blast furnace position, thus enabling coke to be pushed out of the blast furnace. However, when existing coke pushers reach the track maintenance position for equipment maintenance, their large weight makes precise position control difficult, often resulting in collisions when reaching the recovery position. This causes damage to the external structure of the coke pusher or other equipment structures. Furthermore, the position control in most applications relies on position sensors or light sensors, which are prone to malfunction and errors in dusty workshops. Current solutions often involve frequently wiping the sensor probes to improve the stability of the travel direction adjustment, but this requires manual entry, which is dangerous and disrupts normal production. Therefore, improvements to the existing coke pusher direction adjustment device are needed to address these issues. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the purpose of this application is to provide a coal pusher car recovery direction adjustment device that offers good stability, prevents personnel from entering, provides good safety performance, is unaffected by dust, and effectively improves the accuracy of control and adjustment.

[0004] The above-mentioned objective of this application is achieved through the following technical solution:

[0005] A traveling direction adjustment device for a coal coke pusher includes a track body and a trolley body, comprising: a connecting frame, a chute, a slide rod, a sliding block, a guide rod, a helical spring, a stop block, a connecting rod, a pressure plate, a connecting shaft, a connecting block, and a pin. The connecting frame is horizontally U-shaped, and its two sides are fixedly connected to the inner walls of two track bodies. One end of the connecting frame faces the side from which the trolley body is approaching. The chute is respectively opened at the middle position on both sides of the connecting frame. Sliding blocks are fixedly connected to both ends of the slide rod, and the sliding blocks are slidably connected in the chute. Two guide rods are arranged parallel to the track body, and one end of each guide rod is respectively connected to the outer surface of the middle position of the slide rod on both sides. The guide rods are connected face to face. The other ends of each guide rod slide through the middle of the other side of the connecting frame. The stops are fixedly connected to the surface of the guide rod near the slide rod. The helical spring is movably sleeved on the guide rod between the stop and the connecting frame. There are two connecting rods. One end of each connecting rod is movably connected to the outer surface of the slide rod near the middle position. The pressure plate is set on the opening side of the connecting frame. Connecting shafts are fixedly connected to the two sides of the pressure plate away from the connecting frame. The connecting shafts are rotatably connected to the corresponding track body. The connecting block is fixedly connected to the lower surface of the pressure plate near the middle position of the connecting frame. The other end of each connecting rod is movably connected to the connecting block through a pin.

[0006] Optionally, it also includes wear-resistant plates, which are fixedly connected to the surface of the lowest end of the trolley body, and the wear-resistant plates are connected to the upper surface of the pressure plate.

[0007] Optionally, a wear-resistant plate is also included, which is fixedly connected to the upper surface of the pressure plate.

[0008] Optionally, it also includes connectors, which are symmetrically fixed to the inner surface of the unopened end of the connector frame.

[0009] Optionally, a control module is also included, which is fixedly connected to the outer surface of the connecting frame at the middle position away from the opening.

[0010] Optionally, a limiting sleeve is also included, which is fixedly connected to the surface of the connecting frame corresponding to the guide rod, and the guide rod is slidably connected to the limiting sleeve.

[0011] The coal pusher car recovery travel direction adjustment device, through a combined structure, can use the chute structure as a resistive structure, thereby changing the distance between the sliding block and the connector during the movement of the sliding block, thus realizing the control of electrical variables and timely obtaining position information;

[0012] This coal pusher car recovery travel direction adjustment device can magnify the position of the trolley body used for pushing coke, and then use a mechanical structure to collect the position in the travel direction. Compared with existing infrared light sensors and other types of distance sensors, the reliability is greatly improved, and no modifications are required to the existing equipment, making it highly adaptable.

[0013] The coal pusher car recovery direction adjustment device has double-sided chutes that allow for two-way position information acquisition, thereby significantly improving control accuracy, facilitating normal direction adjustment, and reducing collisions during direction changes.

Detailed Implementation

[0017] The present application will be further described in detail below with reference to the accompanying drawings.

[0018] To better understand the technical solutions presented in the embodiments of this application, the working principle of the existing coal coke pusher recovery direction adjustment device will first be introduced.

[0019] In the existing coke pusher recovery process, braking and other information are controlled using signals from external sensors. When a certain position is reached, power is cut off and braking occurs. However, existing sensors are mostly ultrasonic and light sensors, which are prone to malfunction in the high dust, high temperature, and high decibel noise environment of coal mines. This affects the position control of the recovered coke pusher. Therefore, in the current process, personnel need to wipe the probes frequently. However, the environment in coal mines is complex and dangerous, and manual control is not suitable. Some existing structures have automatic water spray cleaning probes, but these structures can damage the probes. In addition, after the automatic cleaning equipment is installed, supporting structures such as wastewater collection equipment are required, which increases the complexity of the monitoring equipment installation. Therefore, it is necessary to improve the existing travel direction adjustment device to enhance its stability and ensure accurate control of the travel position.

[0020] Please see Figure 1 and Figure 2 This application discloses a coal coke pusher recovery direction adjustment device, comprising a track body 1 and a trolley body 18. It is characterized by including: a connecting frame 2, a chute 3, a slide rod 4, a sliding block 41, a guide rod 5, a helical spring 6, a stop block 7, a connecting rod 8, a pressure plate 9, a connecting shaft 10, a connecting block 11, and a pin 12. The connecting frame 2 is horizontally U-shaped, with both sides fixedly connected to the inner walls of the two track bodies 1. One end of the opening of the connecting frame 2 faces the side from which the trolley body 18 approaches. The chute 3 is respectively opened at the middle position on both sides of the connecting frame 2. Sliding blocks 41 are fixedly connected to both ends of the slide rod 4, and the sliding blocks 41 are slidably connected within the chute 3. Two guide rods 5 are arranged parallel to the track body 1, with one end of each guide rod 5... The guide rods 5 are connected to the outer surfaces on both sides of the middle position of the slide rod 4. The other ends of each guide rod 5 slide through the middle of the other side of the connecting frame 2. The stop blocks 7 are fixedly connected to the surface of the guide rod 5 near the middle position of the slide rod 4. The spiral spring 6 is movably sleeved on the guide rod 5 between the stop block 7 and the connecting frame 2. There are two connecting rods 8. One end of each connecting rod 8 is movably connected to the outer surface of the slide rod 4 near the middle position. The pressure plate 9 is set on the opening side of the connecting frame 2. The two sides of the pressure plate 9 away from the connecting frame 2 are fixedly connected to the connecting shafts 10. The connecting shafts 10 are rotatably connected to the corresponding track body 1. The connecting block 11 is fixedly connected to the lower surface of the pressure plate 9 near the middle position of the connecting frame 2. The other end of each connecting rod 8 is movably connected to the connecting block 11 through the pin 12.

[0021] Specifically, during use, the trolley body 18 carries the upper-end coking device and moves on the track body 1. When it reaches a position where braking or stopping is required, it moves at a low speed but does not stop directly. The connecting frame 2 of this application is then positioned at the stop end. When the bottom end of the trolley body 18 contacts the pressure plate 9, the pressure plate 9 swings downward along the connecting shaft 10, thereby moving the lower end of the slide rod 4 via the connecting rod 8. In actual use, the sliding block 41 at the end of the slide rod 4 can be made of graphite due to its good conductivity. The inner wall of the slide groove 3 acts as a conductor, thus changing the distance from the closed end of the connecting frame 2 when the sliding block 41 slides. In terms of material, the connecting frame 2 can be made of nickel-chromium alloy or can be placed only on the inner wall of the slide groove 3. A layer of nickel-chromium alloy resistive material, upon being energized, generates changes in voltage and other electrical signals through positional changes. These changes, controlled by the control module 16, control the trolley body 18, thereby adjusting its direction or state based on the information. The guide rod 5 ensures the track of the slide bar 4 remains balanced during movement, and the helical spring 6 pushes the stop block 7 when the trolley body 18 moves away, thus pushing one end of the pressure plate 9 back up. This mechanical signal acquisition mechanism allows for the separate reception of information from both sides. Compared to existing single-sensor systems, the failure rate is significantly reduced. The accuracy of this information allows for adjustments to the direction of travel, while reducing manpower, minimizing the occurrence of dangerous situations, and greatly improving the safety of the coke pushing equipment during recovery.

[0022] Please see Figure 2 As another specific embodiment provided in the application, it also includes wear-resistant plates 13, which are fixedly connected to the surface of the lowest end of the trolley body 18, and the wear-resistant plates 13 are connected to the upper surface of the pressure plate 9.

[0023] Specifically, the wear-resistant plate 13 can padded the lower end of the trolley body 18, allowing its position to be adjusted, while avoiding bottom wear caused by contact with the pressure plate 9, thus ensuring a longer service life.

[0024] Please see Figure 1 As another specific embodiment provided in the application, it also includes a wear-resistant plate 14, which is fixedly connected to the upper surface of the pressure plate 9.

[0025] Specifically, the wear-resistant plate 14 can protect the surface of the pressure plate 9 and extend its service life.

[0026] Please see Figure 2 As another specific embodiment provided in the application, it also includes a connector 15, which is symmetrically fixedly connected to the inner surface of the unopened end of the connector 2.

[0027] Specifically, the connector 15 can connect the ends of cables, resistance wires and other structures, which facilitates the connection of the circuit. It can directly connect to the resistor sleeve and other structures set in the connector 2 or the slide 3 according to the actual situation, thus improving the convenience of connection.

[0028] Please see Figure 1 As another specific embodiment provided in the application, it also includes a control module 16, which is fixedly connected to the outer surface of the middle position of the connecting frame 2 away from the opening.

[0029] Specifically, the control module 16 can convert the electrical information of the sliding block 41 after it moves into the form of electrical signal control and transmit it to the control structure of the trolley body 18. It should be noted that the information in use is generated simultaneously with other monitoring, rather than displacement control information. This form can supplement the existing structure and achieve a lower accident rate and more precise control of the direction of travel.

[0030] Please see Figure 1 As another specific embodiment provided in the application, it also includes a limiting sleeve 17, which is fixedly connected to the surface of the connecting frame 2 corresponding to the guide rod 5, and the guide rod 5 is slidably connected to the limiting sleeve 17.

[0031] Specifically, the setting of the limiting sleeve 17 can guide and limit the operation of the guide rod 5, so that its sliding trajectory remains parallel to the track body 1, and ensure that the sliding blocks 41 used for measurement on both sides run smoothly.

[0032] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
