Description

Technical Field

[0001] This utility model relates to the field of coke oven vehicle technology, and in particular to a conductive slider for the electrical circuit of the four main grinding wheels of a coke oven to prevent derailment. Background Technology

[0002] The four main cars of a coke oven (coal charging car, coke pushing car, coke quenching car, and coke quenching car) are the core mobile equipment in coke oven production. To ensure their continuous operation, the four cars typically obtain power through a grinding and quenching system. In this system, a conductive slider, as a key current collector, is installed on the four cars, moves with them, and maintains sliding contact with the grinding and quenching system, thereby continuously supplying power to the cars.

[0003] However, during the testing of the four main coke oven cars after the new cars are installed, due to differences in installation standards and on-site working conditions, dimensional deviations may occur when the newly installed cars are matched with the on-site electric grinding track. This can cause the conductive slider to derail during movement, affecting normal power supply. Secondly, during long-term production, the electric grinding track will undergo a certain degree of deformation and foundation changes due to frequent use, leading to local deformation of the track or lateral offset of the track. This can also cause the conductive slider to derail during movement, resulting in power outages. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides a conductive slider for the electrical tracks of the four main grinding mills of a coke oven to prevent derailment. The technical solution of this utility model is as follows: A conductive slider for the electrical track of the four main cars of a coke oven to prevent derailment includes a conductive slider body slidably disposed on the electrical track and at least one pair of extended conductive blocks. The upper end of the conductive slider body is fixedly fitted with an outer frame. The lower surface of the conductive slider body has symmetrically opened transverse side sliding grooves on the left and right sides. Two of the extended conductive blocks in each pair are slidably connected in the side sliding grooves on the corresponding side. The inside of the side sliding grooves is also connected to a tension spring for driving the extended conductive blocks to retract laterally back to their original position. The two ends of the tension springs are respectively connected to the conductive slider body and the extended conductive blocks. The inside of the conductive slider body is also connected to an elastic spring for maintaining the electrical path connection between the conductive slider body and the extended conductive blocks. The extended conductive block includes a slider and a side stop. The slider is laterally slidably connected in a side groove at a corresponding position, and the lower surface of the slider is flush with the lower surface of the conductive slider body. The side stop is fixedly connected to the end of the slider away from the central axis of the conductive slider body, and the lower end of the side stop is lower than the lower surface of the slider and located to the side of the grinding channel.

[0005] Optionally, a mounting hole is provided inside the side sliding groove and at one end near the central axis of the conductive slider body. One end of the tension spring is fixedly connected to an end seat, which is threaded into the mounting hole at the corresponding position. An adjustment through hole is provided transversely inside the slider and the side stop block. An elastic adjustment component is connected inside the adjustment through hole, and the elastic adjustment component is connected to the other end of the tension spring.

[0006] Optionally, the elastic adjustment assembly includes an inner cylinder, an adjustment cylinder, an adjustment block, and an adjustment column. The inner cylinder is fixedly connected inside the adjustment through hole at one end near the central axis of the conductive slider body. The adjustment cylinder is fixedly connected inside the adjustment through hole at one end away from the central axis of the conductive slider body. The adjustment block is laterally slidably connected inside the inner cylinder. The adjustment column is threadedly connected inside the adjustment cylinder. A connecting rod is also provided between the adjustment block and the adjustment column. One end of the connecting rod is rotatably connected to the adjustment block, and the other end of the connecting rod is fixedly connected to the adjustment column.

[0007] Optionally, the extended conductive blocks are provided in two pairs. The front and rear side walls of the conductive slider body are both provided with mounting grooves that communicate with the side sliding grooves. The mounting grooves are located near the left and right sides of the conductive slider body. The mounting grooves are also fixedly connected to the ear seats. The slider has multiple parallel conductive grooves on the side near the mounting groove. The elastic spring includes a V-shaped piece, multiple conductive fingers, and ear plates. The multiple conductive fingers are fixedly connected to one end of the V-shaped piece, and the conductive fingers elastically abut against the conductive grooves at the corresponding positions. The ear plates are fixedly connected to the other end of the V-shaped piece, and the ear plates are fixedly connected to the ear seats by screws.

[0008] Optionally, the inner side of the outer frame is also connected to a sensing component for sensing when a single set of extended conductive blocks reaches its limit position. The sensing component includes an outer cylinder, a short column, and a sensor. The outer cylinder is connected inside the outer frame. The short column is slidably connected to the lower end of the inner side of the outer cylinder. A hemispherical head is fixedly connected to the lower end of the short column. A compression spring is fixedly connected inside the outer cylinder and at the upper end of the short column. A sensor is fixedly connected inside the outer cylinder and inside the compression spring. A limiting block that cooperates with the hemispherical head is fixedly connected to the upper surface of the slider and the side away from the side stop. The limiting block has an inclined surface facing the side stop. A through groove corresponding to the side sliding groove is opened through the upper surface of the conductive slider body, and the through groove is connected to the side sliding groove. The limiting block is located inside the through groove. When the extended conductive block slides to its limit position, the hemispherical head gradually contacts the inclined surface of the limiting block, pushing the short column upward to compress the spring and trigger the sensor.

[0012] All of the above optional technical solutions can be combined arbitrarily, and this utility model does not provide a detailed description of the structure after each combination.

[0013] The beneficial effects of this utility model through the above solution are as follows: 1. This utility model, by setting at least one pair of extended conductive blocks on the conductive slider body, enables automatic compensation and adjustment of the conductive position when the grinding track undergoes lateral displacement or deformation. When the grinding track shifts laterally, the side wall of the grinding track contacts the side stop block, pushing the entire extended conductive block outward against the force of the tension spring, thereby increasing the effective contact area with the grinding track. This structure ensures that even if the grinding track deforms or shifts laterally, causing the lower surface of the conductive slider body to detach from the grinding track, the extended conductive block can still maintain effective contact with the grinding track, continuing the continuous power supply and avoiding the risk of power interruption. During this process, the side stop block is always stuck to the side of the grinding track, forming a mechanical limit, fundamentally preventing the conductive slider body from detaching from the grinding track. After the grinding track returns to its normal position, the tension spring pulls the extended conductive block back into place.

[0014] 2. By setting an elastic spring, the extension conductive block can maintain an electrical path connection with the conductive slider body during the outward extension process, effectively avoiding electrical path interruption or poor contact caused by the sliding gap between the extension conductive block and the conductive slider body.

[0018] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0019] Please see Figure 1-9This utility model provides a conductive slider for the four main grinding tracks of a coke oven to prevent derailment. It includes a conductive slider body 1 slidably mounted on the grinding track 9 and at least one pair of extended conductive blocks 4. The upper end of the conductive slider body 1 is fixedly fitted with an outer frame 2. The lower surface of the conductive slider body 1 is symmetrically provided with transverse side sliding grooves 11 on the left and right sides. The two extended conductive blocks 4 in each pair are slidably connected in the side sliding groove 11 on the corresponding side. The inside of the side sliding groove 11 is also connected with a tension spring 5 for driving the extended conductive blocks 4 to retract laterally and return to their original position. The two ends of the tension spring 5 are respectively connected to the conductive slider body 1 and the extended conductive blocks 4. The inside of the conductive slider body 1 is also connected with an elastic spring 7 for maintaining the electrical path connection between the conductive slider body 1 and the extended conductive blocks 4. The extended conductive block 4 includes a slider 41 and a side stop 42. The slider 41 is laterally slidably connected in the side slide groove 11 at the corresponding position. The end of the side slide groove 11 is provided with a receiving groove 12 for accommodating the side stop 42. The lower surface of the slider 41 is flush with the lower surface of the conductive slider body 1. The side stop 42 is fixedly connected to the end of the slider 41 away from the central axis of the conductive slider body 1. The lower end of the side stop 42 is lower than the lower surface of the slider 41 and is located on the side of the grinding channel 9.

[0020] This invention achieves automatic compensation and adjustment of the conductive position when the grinding track 9 undergoes lateral displacement or deformation by providing at least one pair of extended conductive blocks 4 on the conductive slider body 1. When the grinding track 9 shifts laterally, the side wall of the grinding track 9 contacts the side stop 42 and pushes the entire extended conductive block 4 outward against the force of the tension spring 5, thereby increasing the effective contact area with the grinding track 9. This structure ensures that even if the grinding track 9 undergoes lateral deformation or displacement, causing the lower surface of the conductive slider body 1 to detach from the grinding track 9, the extended conductive block 4 can still maintain effective contact with the grinding track 9, continuing the continuous power supply and avoiding the risk of power interruption. During this process, the side stop 42 is always stuck on the side of the grinding track 9, forming a mechanical limit and fundamentally preventing the conductive slider body 1 from detaching from the grinding track 9. After the grinding track 9 returns to its normal position, the tension spring 5 pulls the extended conductive block 4 back into place.

[0021] Secondly, by setting the elastic spring 7, the extension conductive block 4 can always maintain an electrical path connection with the conductive slider body 1 during the process of the extension conductive block 4 extending outward, effectively avoiding the interruption of the electrical path or poor contact caused by the sliding gap between the extension conductive block 4 and the conductive slider body 1.

[0022] Furthermore, a mounting hole 14 is provided inside the side slide groove 11 and at one end near the central axis of the conductive slider body 1. One end of the tension spring 5 is fixedly connected to an end seat 51, which is threaded into the mounting hole 14 at the corresponding position. An adjustment through hole 43 is provided transversely inside the slider 41 and the side stop 42. An elastic adjustment component 6 is connected inside the adjustment through hole 43, and the elastic adjustment component 6 is connected to the other end of the tension spring 5.

[0023] Specifically, the end seat 51 is threaded into the mounting hole 14, facilitating the subsequent disassembly and replacement of the tension spring 5. Secondly, the effective length or initial tension of the tension spring 5 can be changed through the spring force adjustment component 6, thereby ensuring that the tension force of the tension spring 5 remains stable, thus providing a stable rebound force for the reset of the extension conductive block 4.

[0024] Furthermore, the elastic adjustment assembly 6 includes an inner cylinder 61, an adjustment cylinder 62, an adjustment block 63, and an adjustment column 65. The inner cylinder 61 is fixedly connected inside the adjustment through hole 43 and at one end close to the central axis of the conductive slider body 1. The adjustment cylinder 62 is fixedly connected inside the adjustment through hole 43 and at one end away from the central axis of the conductive slider body 1. The adjustment block 63 is laterally slidably connected inside the inner cylinder 61. The adjustment column 65 is threadedly connected inside the adjustment cylinder 62. A connecting rod 64 is also provided between the adjustment block 63 and the adjustment column 65. One end of the connecting rod 64 is rotatably connected to the adjustment block 63, and the other end of the connecting rod 64 is fixedly connected to the adjustment column 65.

[0025] Specifically, the head of the adjusting column 65 is provided with a rotating groove 651, which facilitates the operator to rotate the adjusting column 65. Secondly, the inner sidewall of the inner cylinder 61 is provided with multiple sets of limiting grooves 611 along its length, and the outer sidewall of the adjusting block 63 is fixedly connected with multiple sets of limiting ribs 631 that cooperate with and slide in the limiting grooves 611, thereby ensuring that the adjusting block 63 always slides along the direction of the limiting grooves 611 during the sliding process. In addition, when the adjusting column 65 is rotated, axial forward and backward movement will occur under the threaded engagement between the adjusting column 65 and the adjusting cylinder 62. At this time, the movement of the adjusting column 65 will push or pull the adjusting block 63 to slide linearly in the inner cylinder 61 through the connecting rod 64, thereby changing the initial tension length of the tension spring 5, and thus realizing the adjustment of the elastic force of the tension spring 5.

[0026] Furthermore, the extended conductive block 4 is provided in two pairs. The front and rear side walls of the conductive slider body 1 are provided with mounting grooves 13 that are connected to the side sliding grooves 11. The mounting grooves 13 are located near the left and right sides of the conductive slider body 1. The inside of the mounting grooves 13 is also fixedly connected to the ear seat 131. The slider 41 has multiple vertically parallel conductive grooves 411 on the side near the mounting grooves 13. The elastic spring 7 includes a V-shaped piece 71, multiple conductive fingers 72 and ear plates 73. The multiple conductive fingers 72 are fixedly connected to one end of the V-shaped piece 71 and the conductive fingers 72 elastically abut against the corresponding conductive grooves 411. The ear plate 73 is fixedly connected to the other end of the V-shaped piece 71 and the ear plate 73 is fixedly connected to the ear seat 131 by screws.

[0027] Specifically, two pairs of extended conductive blocks 4 are provided, that is, four sets of extended conductive blocks 4 are distributed in pairs on the left and right sides of the conductive slider body 1. Secondly, the elastic spring 7 is fixed to the ear seat 131 with screws for easy maintenance and replacement. The side cover 122 is also detachably installed on the outside of the mounting groove 13 with screws. In addition, multiple sets of parallel conductive grooves 411 are provided on the side of the slider 41, which greatly increases the current path and contact area. The multiple conductive fingers 72 of the elastic spring 7 are elastically pressed into these conductive grooves 411. Even if individual conductive fingers 72 have poor contact due to wear or contamination, the other conductive fingers 72 can still ensure the current flow, which significantly improves the reliability of power transmission.

[0028] Specifically, the electrical path between the extended conductive block 4 and the conductive slider body 1 is: extended conductive block 4 - elastic spring 7 - ear seat 131 - conductive slider body 1.

[0029] Furthermore, the inner side of the outer frame 2 is also connected to a sensing component 8 for sensing that a single set of extended conductive blocks 4 has reached the limit position. The sensing component 8 includes an outer cylinder 81, a short column 82 and a sensor 84. The outer cylinder 81 is connected inside the outer frame 2. The short column 82 is slidably connected to the lower end of the inner side of the outer cylinder 81. The lower end of the short column 82 is fixedly connected to a hemispherical head 821. A compression spring 83 is fixedly connected inside the outer cylinder 81 and at the upper end of the short column 82. A sensor 84 is fixedly connected inside the outer cylinder 81 and inside the compression spring 83. A limiting block 44 that cooperates with the hemispherical head 821 is fixedly connected to the upper surface of the slider 41 and the side away from the side stop 42. The limiting block 44 has an inclined surface facing the side stop 42. A through groove 15 corresponding to the side slide groove 11 is opened through the upper surface of the conductive slider body 1. The through groove 15 is connected to the side slide groove 11. The limiting block 44 is located inside the through groove 15. When the extended conductive block 4 slides to its limit position, the hemispherical head 821 gradually contacts the inclined surface of the limiting block 44, pushing the short column 82 upward to compress the spring 83 and trigger the sensor 84.

[0030] Specifically, under normal conditions, the compression spring 83 pushes out the short column 82 and its lower hemispherical head 821, and the sensor 84 is in an untriggered state. When the extended conductive block 4 slides outward to near its limit position, the limiting block 44 on the slider 41 moves accordingly. The inclined surface of the limiting block 44 begins to contact the lower hemispherical head 821 of the short column 82. The hemispherical head 821 slides upward along the inclined surface, pushing the short column 82 and displacing it upward. At this time, the compression spring 83 is compressed, and the upper end of the short column 82 eventually touches the sensor 84. The sensor 84 will send an electrical signal indicating that the limit position has been reached to the control terminal of the four main cars of the coke oven. After the extended conductive block 4 resets, the hemispherical head 821 disengages from the limiting block 44. At this time, the compression spring 83 returns to its original deformation and pushes the short column 82 back to its original position. At this time, the sensor 84 loses its electrical signal. Secondly, the limiting block 44, sliding within the through groove 15, can also serve as a limit, preventing the extended conductive block 4 from slipping out of the side sliding groove 11.

[0031] Furthermore, a fixed rail 21 is horizontally fixedly connected inside the outer frame 2 and above the through groove 15. The outer cylinder 81 slides horizontally inside the fixed rail 21. Two sets of locking nuts 85 are threaded on the outer side of the outer cylinder 81, and the two sets of locking nuts 85 abut against the upper and lower sides of the fixed rail 21 respectively.

[0032] Specifically, by rotating the two sets of locking nuts 85, the outer cylinder 81 can be easily moved to the optimal sensing position, and then the two sets of locking nuts 85 can be firmly clamped onto the fixed rail 21 from the top and bottom.

[0033] Furthermore, sensor 84 is a contact sensor.

[0034] Specifically, the contact sensor is electrically connected to the control terminal of the four main cars of the coke oven. When the contact sensor receives a trigger signal, it will transmit it to the control terminal of the four main cars of the coke oven.

[0035] Furthermore, the upper end of the outer frame 2 is fixed with an end cover 3 by bolts, and the end cover 3 is fixedly connected to the four cars of the coke oven by a bracket.

[0036] Specifically, the conductive slider body 1 is mounted on the four main cars of the coke oven via a bracket on the end cover 3. When maintenance or replacement of the entire conductive slider body 1 is required, simply disconnect the car body connection line to the conductive slider body 1 and separate the conductive slider body 1 from the end cover 3 to remove the entire conductive slider body 1, which greatly simplifies the disassembly and assembly process and reduces equipment downtime.

[0037] The above are merely preferred embodiments of this utility model and are not intended to limit this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
