Description

Technical Field

[0001] This utility model relates to the field of furnace door detection technology, and in particular to a signal triggering device for an SCP furnace door. Background Technology

[0002] In the coking process, in order to achieve efficient coal charging and coke discharging, the coke oven doors need to be opened and closed frequently by a door-opening machine.

[0003] During the door removal process, the door hook relies on the support of the furnace door's load-bearing column to lift the furnace door. Therefore, the door hook needs to be supported by the load-bearing column during operation. However, existing door removal machines are not equipped with a signal detection system to detect whether the load-bearing column is properly positioned. This means that if the door hook fails to accurately lift the load-bearing column, the door removal operation may fail, resulting in the furnace door being unable to open smoothly or operational obstacles.

[0004] Similarly, when the furnace door is being removed or closed, the door-pressing cylinder needs to retract to push the door crossbar out and engage it with the inside of the door mounting slot. However, existing door removal machines lack a signal detection mechanism to determine whether the door crossbar is properly engaged. This means that if the door-pressing cylinder malfunctions and fails to retract in time, the door crossbar may not be able to pop out and engage properly, resulting in the furnace door failing to close smoothly. Such a malfunction not only affects the normal operating efficiency of the door removal machine but may also cause a series of safety hazards, impacting the stability and production efficiency of the coking process. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this utility model provides an SCP furnace door signal triggering device. The technical solution of this utility model is as follows:

[0006] An SCP machine furnace door signal triggering device includes four sets of triggering components 1 for monitoring whether the furnace door crossbar is closed in place and one set of triggering components 2 for monitoring whether the furnace door force column is placed in place. The four sets of triggering components 1 are installed in pairs at the upper and lower ends of the door removal frame. The two sets of triggering components 1 located at the same height correspond to the left and right sides of the furnace door crossbar. The triggering components 2 are installed on one of the door lifting hooks.

[0007] The triggering component includes a C-shaped frame and a movable seat. The C-shaped frame is connected to the door removal frame, and the movable seat is slidably connected to the inner side of the C-shaped frame. The front end of the movable seat is fixedly connected to an abutment block via a connecting column. Elastic pushers are connected to both the left and right sides of the C-shaped frame. The elastic pushers elastically abut the abutment block against the horizontal iron of the furnace door. A sensor for sensing the position of the movable seat is connected to the vertical side of the C-shaped frame.

[0008] The upper surface of the door lifting hook has a through-hole. The triggering component two includes a movable rod, a support column, and a balance rod. The movable rod is slidably connected inside the movable hole. The support column is fixedly connected to the door lifting frame and located at the lower right corner of the door lifting hook. The middle part of the balance rod is rotatably connected to the front end of the support column via a shaft. One end of the balance rod is connected to a gravity block, and the other end of the balance rod is connected to the lower end of the movable rod. A sensor two is fixedly installed at the front end of the door lifting frame and below the door lifting hook. The gravity block lifts the movable rod through the balance rod.

[0009] Optionally, the C-shaped frame includes a vertical plate and two sets of slide rails. The two sets of slide rails are symmetrically fixed on the upper and lower ends of the front surface of the vertical plate, and the upper and lower surfaces of the movable seat are fixedly connected with pulley sets that cooperate with the corresponding slide rails.

[0010] Optionally, the elastic sliding component includes two sets of fixed plates and two sets of sliding rods. The two sets of fixed plates are respectively fixedly connected to the left and right sides of the front opening of the C-shaped frame. The two sets of sliding rods are respectively located on the left and right sides of the movable seat. The front ends of the two sets of sliding rods are respectively fixedly connected to the two sets of fixed plates, and the rear ends of the two sets of sliding rods are respectively fixedly connected to the left and right sides of the front surface of the vertical plate. A spring is sleeved on the outside of the sliding rod. Guide sleeves that cooperate with the sliding rods are fixedly connected to the left and right sides of the movable seat. The springs abut against the vertical plate and the guide sleeves.

[0011] Optionally, a threaded hole is provided through the center of the vertical plate, and a threaded sleeve is threadedly connected inside the threaded hole. The sensor is fixedly connected to the front end of the threaded sleeve.

[0012] Optionally, the sensor may be a contact sensor.

[0013] Optionally, the lower end of the side wall of the movable rod is provided with a movable groove to provide space for the balance bar to move.

[0014] Optionally, the lower end of the movable rod is fixedly connected to a contact plate for triggering sensor two.

[0015] Optionally, the second sensor is a pneumatic mechanical valve.

[0016] Optionally, the lower surface of the lifting hook has a cavity, the lower end of the movable hole is connected to the cavity, the movable rod is threaded with a limiting nut on the outer side of the cavity, a limiting plate is fixedly connected inside the cavity, a through hole is opened through the front end of the surface of the limiting plate, the movable rod is slidably connected inside the through hole, and the size of the limiting nut is larger than the size of the through hole.

[0017] 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.

[0018] The beneficial effects of this utility model through the above solution are as follows:

[0019] This invention achieves timely monitoring of the closure status of the furnace door crossbar by incorporating a trigger component. When the furnace door crossbar is closed, the abutment blocks, under the action of the elastic pushing component, can abut against the left and right sides of the crossbar through elastic force. As the furnace door closes further, the door-opening mechanism's hydraulic cylinder begins to retract, and the furnace door crossbar automatically pops out, pressing the two sets of abutment blocks backward. At this time, the two abutment blocks respectively push their connected movable seats backward until the movable seats trigger sensor one. After receiving the trigger signal, the two sets of sensors indicate that the furnace door crossbar has closed completely, ensuring that the closing status of the furnace door crossbar is monitored in a timely and accurate manner.

[0020] Furthermore, by setting up trigger component two, the placement of the furnace door force-bearing column can be monitored. When the furnace door force-bearing column is correctly placed inside the lifting hook, it will press down on the movable rod, which triggers sensor two. When sensor two receives the trigger signal from the movable rod, it can confirm that the furnace door force-bearing column has been fully placed on the lifting hook, ensuring the correct placement of the furnace door force-bearing column.

[0032] 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.

[0033] Please see Figure 1-9 This utility model provides an SCP machine furnace door signal triggering device, including four sets of trigger components 1 5 for monitoring whether the furnace door horizontal iron 1 is closed in place and one set of trigger components 2 6 for monitoring whether the furnace door force column 2 is placed in place. The four sets of trigger components 1 5 are installed in pairs at the upper and lower ends of the door removal frame 3. The two sets of trigger components 1 5 located at the same height correspond to the left and right sides of the furnace door horizontal iron 1 respectively. The trigger components 2 6 are installed on one of the door lifting hooks 4.

[0034] Trigger component 5 includes a C-shaped frame 51 and a movable seat 52. The C-shaped frame 51 is connected to the door removal frame 3. The movable seat 52 is slidably disposed inside the C-shaped frame 51. The front end of the movable seat 52 is fixedly connected to an abutment block 53 via a connecting column. Elastic pushers 54 are connected to both the left and right sides of the C-shaped frame 51. The elastic pushers 54 elastically abut the abutment block 53 against the furnace door cross iron 1. A sensor 56 for sensing the position of the movable seat 52 is connected to the vertical side of the C-shaped frame 51.

[0035] The upper surface of the door hook 4 has a through hole 41. The trigger assembly 6 includes a movable rod 61, a support column 62, and a balance rod 63. The movable rod 61 is slidably connected inside the movable hole 41. The support column 62 is fixedly connected to the door lifting frame 3 and located at the lower right corner of the door hook 4. The middle part of the balance rod 63 is rotatably connected to the front end of the support column 62 through a shaft. One end of the balance rod 63 is connected to a gravity block 64, and the other end of the balance rod 63 is connected to the lower end of the movable rod 61. A sensor 66 is fixedly installed at the front end of the door lifting frame 3 and below the door hook 4. The gravity block 64 lifts the movable rod 61 through the balance rod 63.

[0036] This invention achieves timely monitoring of the closing status of the furnace door crossbar 1 by setting a trigger component 5. When the furnace door crossbar 1 is closed, the abutment blocks 53, under the action of the elastic pushing member 54, can abut against the left and right sides of the furnace door crossbar 1 through elastic force. As the furnace door closes further, the door-opening machine's door-pressing cylinder begins to retract, and the furnace door crossbar 1 will automatically pop out and press the two sets of abutment blocks 53 backward. At this time, the two abutment blocks 53 respectively push their connected movable seats 52 to move backward until the movable seats 52 trigger the sensors 56. After receiving the trigger signal, the two sets of sensors 56 indicate that the furnace door crossbar 1 has been closed in place, ensuring that the closing status of the furnace door crossbar 1 is monitored in a timely and accurate manner. Secondly, during the door removal process, when the door-pressing cylinder pushes the furnace door horizontal iron 1 inward, the abutment block 53 is acted upon by the elastic pushing member 54 and will also move inward along with the furnace door horizontal iron 1. At this time, the sensor 56 will lose the signal from the movable seat 52, thereby realizing the monitoring of the state change of the furnace door horizontal iron 1.

[0037] Furthermore, this invention, by setting trigger component 2 6, can monitor the placement of the furnace door force-bearing column 2. When the furnace door force-bearing column 2 is correctly placed inside the lifting hook 4, it will press down on the movable rod 61, triggering the operation of sensor 2 66. When sensor 2 66 receives the trigger signal from the movable rod 61, it can confirm that the furnace door force-bearing column 2 is completely placed on the lifting hook 4, ensuring the correct placement of the furnace door force-bearing column 2. After the door is removed by the door removal machine, the furnace door force-bearing column 2 will detach from the lifting hook 4. At this time, the upper end of the movable rod 61 is no longer restricted. Under the action of the gravity block 64, the movable rod 61 will tilt up, causing sensor 2 66 to lose the signal from the movable rod 61, indicating that the furnace door force-bearing column 2 has detached from the lifting hook 4, ensuring the safety and accuracy of the entire door removal process.

[0038] Furthermore, the C-shaped frame 51 includes a vertical plate 511 and two sets of slide rails 512. The two sets of slide rails 512 are symmetrically fixed on the upper and lower ends of the front surface of the vertical plate 511, and the upper and lower surfaces of the movable seat 52 are fixedly connected with pulley sets 521 that cooperate with the slide rail 512 on the corresponding side.

[0039] Specifically, the pulley block 521 and the slide rail 512 work together to make the movable seat 52 move more smoothly, reduce the influence of friction, and thus improve the sliding efficiency.

[0040] Furthermore, the elastic pushing component 54 includes two sets of fixed plates 541 and two sets of sliding rods 542. The two sets of fixed plates 541 are respectively fixedly connected to the left and right sides of the front opening of the C-shaped frame 51. The two sets of sliding rods 542 are respectively located on the left and right sides of the movable seat 52. The front ends of the two sets of sliding rods 542 are respectively fixedly connected to the two sets of fixed plates 541. The rear ends of the two sets of sliding rods 542 are respectively fixedly connected to the left and right sides of the front surface of the vertical plate 511. A spring 543 is sleeved on the outside of the sliding rod 542. Guide sleeves 522 that cooperate with the sliding rods 542 are fixedly connected to both the left and right sides of the movable seat 52. The spring 543 abuts between the vertical plate 511 and the guide sleeve 522.

[0041] Specifically, the function of spring 543 is to provide elastic pushing force to ensure that the movable seat 52 can be subjected to appropriate rebound force during sliding and maintain a certain stability and positional accuracy.

[0042] Furthermore, a threaded hole 5111 is provided through the center of the vertical plate 511, and a threaded sleeve 55 is threadedly connected inside the threaded hole 5111. The sensor 56 is fixedly connected to the front end of the threaded sleeve 55, and a hexagonal head 551 is fixedly connected to the rear end of the threaded sleeve 55.

[0043] Specifically, the front end of the threaded sleeve 55 contacts the rear side of the movable seat 52, effectively limiting its movement and preventing excessive backward movement. Whenever the door cylinder retracts, the furnace door crossbar 1 pops out automatically and indirectly presses the movable seat 52 backward via the abutment block 53 until the rear side of the movable seat 52 contacts the front side of the threaded sleeve 55, thus stopping the movement. The position of the threaded sleeve 55 in the threaded hole 5111 can be precisely adjusted by turning the hexagonal head 551, allowing for flexible adjustment of the backward movement limit of the movable seat 52. Simultaneously, the sensor 56 is installed inside the threaded sleeve 55, effectively protecting it and preventing direct collision or interference with its operation when the movable seat 52 moves backward.

[0044] Furthermore, sensor 56 employs a contact sensor.

[0045] Specifically, when the movable seat 52 moves rearward, it comes into contact with the contact rod of sensor 56, generating a pressing force. At this time, sensor 56 will detect the touch signal from the movable seat 52 and respond quickly by sending a trigger signal, indicating that the movable seat 52 has reached the predetermined position.

[0046] Furthermore, the lower end of the side wall of the movable rod 61 is provided with a movable groove 611 to provide movable space for the balance bar 63.

[0047] Furthermore, a contact plate 65 for triggering sensor 66 is fixedly connected to the lower end of the movable rod 61.

[0048] Specifically, when the movable rod 61 moves down, the second sensor 66 is triggered by the contact plate 65, so that the second sensor 66 does not need to be installed at the lower end of the movable rod 61, which can protect the second sensor 66 and reduce the possible risk of damage.

[0049] Furthermore, sensor 266 employs a pneumatic mechanical valve.

[0050] Specifically, the pneumatic mechanical valve effectively avoids the direct exposure of electronic components (such as limit switches) to high temperatures, thereby improving the system's high-temperature resistance. This not only enhances the stability of sensor 266 but also extends its service life, ensuring a more stable and reliable monitoring process.

[0051] Furthermore, a cavity 42 is formed on the lower surface of the lifting hook 4, and the lower end of the movable hole 41 is connected to the cavity 42. A limiting nut 612 is threaded on the outer part of the movable rod 61 located in the cavity 42. A limiting plate 67 is fixedly connected inside the cavity 42. A through hole 671 is formed on the front end of the surface of the limiting plate 67. The movable rod 61 is slidably connected inside the through hole 671, and the size of the limiting nut 612 is larger than the size of the through hole 671.

[0052] Specifically, the limiting nut 612 is located on the outside of the movable rod 61, which restricts the vertical movement of the movable rod 61, thus ensuring that the movable rod 61 will not move excessively or fall off during operation. When the gravity block 64 lifts the movable rod 61 through the balance bar 63, the limiting nut 612 on the outside of the movable rod 61 will contact the upper surface of the cavity 42, thereby restricting the upward movement of the movable rod 61. Conversely, when the lifting hook 4 lifts the furnace door support column 2, the external force will cause the movable rod 61 to move downward. At this time, the limiting nut 612 on the outside of the movable rod 61 will abut against the upper surface of the limiting plate 67, ensuring the stable positioning of the movable rod 61 and preventing the movable rod 61 from falling off or becoming unstable due to excessive pressure.

[0053] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present 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 the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
