Description

Technical Field

[0001] This utility model relates to auxiliary tooling for coke oven production, and more particularly to a coke oven testing and transfer combination hoisting tooling. Background Technology

[0002] Coke cans are key equipment in dry quenching systems used for transporting red-hot coke. They consist of a metal shell and an inner lining, capable of withstanding temperatures up to 1050℃. The inner lining is in direct contact with the coke, therefore it must possess properties such as wear resistance, high-temperature resistance, and impact resistance. Because refractory materials offer superior insulation compared to the inner lining, they are currently mostly used instead. However, refractory materials are heavier, significantly increasing the overall weight of the coke can, which can typically reach 50 tons. Therefore, a spreader beam is required for lifting the coke can during testing. Different models of coke cans require spreader beams with corresponding lifting point distances; however, purchasing multiple models of spreader beams is too costly.

[0003] Furthermore, the coke cans are approximately 7 meters wide, which is too wide and hinders their transfer and transportation. Therefore, before transferring the coke cans, the external lifting frames need to be removed, and then the coke cans with the lifting frames removed are lifted using transfer hoisting equipment. Because the mouth of the coke can is bowl-shaped, and the lifting point of the coke can is at the bottom of the can body, the lifting ropes will inevitably squeeze the mouth of the can during the transfer and hoisting process, causing deformation of the mouth, cracking of the refractory material, or even partial detachment. Utility Model Content

[0004] To address the shortcomings of existing technologies, the technical problem to be solved by this utility model is to provide a coke tank testing and transfer combination hoisting fixture that is simple in structure, has good adaptability, and can provide good protection for coke tanks. The testing hoisting fixture in this coke tank testing and transfer combination hoisting fixture can be matched with all models of coke tanks, and the transfer hoisting fixture in this coke tank testing and transfer combination hoisting fixture can effectively protect the tank opening and achieve stable transfer and hoisting of the coke tank.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a coke tank test transfer combined hoisting fixture, comprising: a test hoisting fixture and a transfer hoisting fixture.

[0006] The structure of the test hoisting fixture includes: a spreader beam and a pair of lifting lugs; a test lifting seat is fixedly installed at the center of the top of the spreader beam; the lifting lugs have hooks that can hook onto the lifting points on the coke tank lifting frame outside the coke tank; the lifting lugs have mounting through holes that can be fitted onto the spreader beam, and after the lifting lugs are fitted onto the spreader beam through the mounting through holes, they can slide along the length of the spreader beam; wherein, the power to make the lifting lugs slide can be achieved by manually pushing the lifting lugs.

[0007] The structure of the transfer hoisting fixture includes: a fixture body with four main beams, the distance from the ends of the four main beams to the center of the fixture body is equal, and each end of the main beams is provided with a hoisting rope slot for the hoisting rope to be inserted; an auxiliary beam group is also provided on the fixture body to enhance the load-bearing capacity of the four main beams.

[0008] Furthermore, in the aforementioned coke oven testing and transfer assembly hoisting fixture, a position adjustment mechanism is provided between each lifting lug and the spreader beam for adjusting the position of the lifting lug on the spreader beam. The position adjustment mechanism has the following structure: a first mounting base and a second mounting base are fixedly mounted on the spreader beam; the inner end of a lead screw is rotatably mounted in the first mounting base, and the rear section of the lead screw is rotatably mounted in the second mounting base; a handwheel is fixedly mounted on the outer end of the lead screw extending beyond the second mounting base; a threaded sleeve with an internal thread section is fixedly mounted on the lifting lug, and the threaded sleeve is screwed onto the lead screw located between the first and second mounting bases. When the handwheel is rotated, the lifting lug can slide along the length of the spreader beam by moving the threaded sleeve through the rotation of the lead screw. Changing the direction of rotation of the handwheel changes the direction of movement of the lifting lug.

[0009] Furthermore, in the aforementioned coke oven testing and transfer assembly hoisting fixture, a guide mechanism is provided between each lifting lug and the spreader beam. The guide mechanism consists of a guide rod fixedly installed on the spreader beam, with its axis parallel to the direction of movement of the threaded sleeve. A guide sleeve is fixedly installed on the lifting lug, and the guide sleeve is movably fitted onto the guide rod. This guide mechanism allows the lifting lug to slide more smoothly and steadily along the length of the spreader beam.

[0010] Furthermore, in the aforementioned coke oven test transfer assembly hoisting fixture, the four main beams on the transfer hoisting fixture are arranged in a circumferential sequence as follows: a first main beam, a second main beam, a third main beam, and a fourth main beam; the center lines of the first main beam and the third main beam are on the same straight line, and the center lines of the second main beam and the fourth main beam are on the same straight line.

[0011] Furthermore, in the aforementioned coke oven testing and transfer assembly hoisting fixture, the auxiliary beam group on the transfer hoisting fixture includes four auxiliary beams: a first auxiliary beam, a second auxiliary beam, a third auxiliary beam, and a fourth auxiliary beam; the first auxiliary beam is fixedly connected at both ends to a first main beam and a second main beam, the second auxiliary beam is fixedly connected at both ends to a second main beam and a third main beam, the third auxiliary beam is fixedly connected at both ends to a third main beam and a fourth main beam, and the fourth auxiliary beam is fixedly connected at both ends to a fourth main beam and a first main beam; and the first, second, third, and fourth auxiliary beams form a rectangular frame outline.

[0012] To further improve the overall strength of the transfer and hoisting fixture, a pair of short-side support auxiliary beams can be added to the auxiliary beam group.

The inner ends of the first support auxiliary beam and the second support auxiliary beam are both fixed to the middle of the fixture body. The outer ends of the first support auxiliary beam and the second support auxiliary beam are both fixedly connected to the auxiliary beam closest to the middle of the fixture body. The center lines of the first support auxiliary beam and the second support auxiliary beam are on the same straight line.

[0013] To further enhance the overall strength of the transfer and hoisting fixture, a pair of long-side support auxiliary beams can be added to the auxiliary beam group. The pair of long-side support auxiliary beams includes a third support auxiliary beam and a fourth support auxiliary beam. The inner ends of the third support auxiliary beam and the fourth support auxiliary beam are both fixed to the middle of the fixture body. The outer ends of the third support auxiliary beam and the fourth support auxiliary beam are both fixedly connected to the auxiliary beam furthest from the middle of the fixture body. Furthermore, the center lines of the third support auxiliary beam and the fourth support auxiliary beam are on the same straight line.

[0014] In addition to being separable structures, the test hoisting fixture and the transfer hoisting fixture can also be fixed structures, such as the transfer hoisting fixture being fixed below the test hoisting fixture, or the transfer hoisting fixture being installed below the test hoisting fixture through a detachable connection structure.

Detailed Implementation

[0029] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and preferred embodiments.

[0030] Exemplary embodiments will be described more fully below with reference to the accompanying drawings; however, these exemplary embodiments may be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will enable those skilled in the art to fully understand the scope of this disclosure.

[0031] like Figure 1 , Figure 3 and Figure 12 As shown in this embodiment, a coke tank testing and transfer assembly lifting fixture includes a testing lifting fixture 100 and a transfer lifting fixture 200. The testing lifting fixture 100 and the transfer lifting fixture 200 can be two independent fixtures without any connection between them. Alternatively, the testing lifting fixture 100 and the transfer lifting fixture 200 can be connected by a fixing method, for example, the transfer lifting fixture 200 can be fixed below the testing lifting fixture 100, and the fixing method can be a non-removable fixing method such as welding. The testing lifting fixture 100 and the transfer lifting fixture 200 can also be assembled using a detachable connection structure, for example, the transfer lifting fixture 200 can be installed below the testing lifting fixture 100 through a detachable connection structure, and the detachable connection structure can be a detachable fixing method such as bolt connection.

[0032] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the structure of the test lifting fixture 100 in this embodiment includes: a spreader beam 1 and a pair of lifting lugs 2. A test lifting seat 3 is fixedly installed at the center of the top of the spreader beam 1. The lifting lugs 2 have hooks 7 that can hook onto the lifting points 6 on the coke tank lifting frame 5 outside the coke tank 4; the lifting lugs 2 have mounting through holes 8 that can be fitted onto the spreader beam 1, and after the lifting lugs 2 are fitted onto the spreader beam 1 through the mounting through holes 8, they can slide along the length direction of the spreader beam 1.

[0033] In actual use, the position of a pair of lifting lugs 2 on the spreader beam 1 is adjusted according to the positions of the two lifting points 6 on the coke tank lifting frame 5 outside the coke tank 4, so as to realize the lifting test of coke tanks of different specifications and sizes. The crane hook 20 is connected to the test lifting base 3 through the wire rope 21, and the pair of lifting lugs 2 are respectively hooked to the lifting points 6 on the coke tank lifting frame 5 outside the coke tank 4. Figure 6 and Figure 7As shown, when the test lifting fixture 100 lifts the coke can 4, the valve 19 at the bottom of the coke can 4 will normally open. If the valve 19 at the bottom of the coke can 4 opens smoothly to the set angle, the coke can 4 passes the test. If the valve 19 at the bottom of the coke can 4 cannot open smoothly or does not open properly, the coke can 4 fails the test.

[0034] In addition to manual adjustment, the position of each pair of lifting lugs 2 can also be adjusted by a position adjustment mechanism between each lifting lug 2 and the spreader beam 1. For example... Figure 10 and Figure 11 As shown, the structure of the position adjustment mechanism is as follows: a first mounting base 9 and a second mounting base 10 are fixedly installed on the spreader beam 1; the inner end of the lead screw 11 is rotatably installed in the first mounting base 9; the rear section of the lead screw 11 is rotatably installed in the second mounting base 10; a handwheel 12 is fixedly installed on the outer end of the lead screw 9 extending out of the second mounting base 10; a threaded sleeve 13 with an internal thread section is fixedly installed on the lifting lug 2; the threaded sleeve 13 is screwed onto the lead screw 11 located between the first mounting base 9 and the second mounting base 10.

[0035] The lead screw 11 can be rotatably mounted in the first mounting base 9 and the second mounting base 10. This can be achieved by using a shoulder and a retaining groove to axially limit the lead screw 11 and ensure it does not interfere with its rotation. Alternatively, a bearing 16 can be used to support the lead screw 11, or a combination of both methods can be used. No specific requirements are set here, as long as the lead screw 11 is supported and prevents axial movement, rotating smoothly only around its own axis.

[0036] In actual use, the handwheels 12 are rotated according to the positions of the two lifting points 6 on the coke tank lifting frame 5 outside the coke tank 4. The lead screw 11 rotates around its own axis, forcing the threaded sleeve 13 that it meshes with to move along the axial direction of the lead screw 11. The direction of rotation of the handwheels 12 controls the direction of movement of the threaded sleeve 13, ultimately achieving the purpose of moving the pair of lifting lugs 2 to the required position on the spreader beam 1. In addition, scale markings can be set on the spreader beam 1 to more intuitively understand the position of the lifting lugs 2.

[0037] To ensure the smoother sliding of the lug 2 along the length of the spreader beam 1, this embodiment can also include a guide mechanism between each lug 2 and the spreader beam 1. For example... Figure 10 and 11As shown, the structure of the guiding mechanism is as follows: the guide rod 14 is fixedly installed on the spreader beam 1, and the axis of the guide rod 14 is parallel to the moving direction of the threaded sleeve 13; a guide sleeve 15 is fixedly installed on the lifting lug 2, and the guide sleeve 15 is movably sleeved on the guide rod 14. A self-lubricating bushing can also be provided inside the guide sleeve 15 to improve the smoothness of the sliding of the guide sleeve 15.

[0038] The guide rod 14 can be fixed by setting a third mounting base 17 on the spreader beam 1 to fix the guide rod 14, or by setting a third mounting base 17 and a fourth mounting base 18 on the spreader beam 1 to fix the guide rod 14 together.

[0039] like Figure 3 , Figure 4 , Figure 8 and Figure 9 As shown, the structure of the transfer and hoisting fixture 200 in this embodiment includes: a fixture body with four main beams, the distance from the ends of the four main beams to the center of the fixture body being equal, and the four main beams being sequentially arranged circumferentially as: first main beam 22, second main beam 23, third main beam 24, and fourth main beam 25. Each main beam end is provided with a hoisting rope slot 27 for the hoisting rope 26 to be inserted; auxiliary beam groups are also provided on the fixture body to enhance the load-bearing capacity of the four main beams.

[0040] A more preferred embodiment is to place the centerline of the first main beam 22 and the centerline of the third main beam 24 on the transfer hoisting fixture 200 on the same straight line, and to place the centerline of the second main beam 23 and the centerline of the fourth main beam 25 on the same straight line.

[0041] like Figure 3 and Figure 4 As shown, the auxiliary beam group in this embodiment includes four auxiliary beams: a first auxiliary beam 28, a second auxiliary beam 29, a third auxiliary beam 30, and a fourth auxiliary beam 31. The first auxiliary beam 28 is fixedly connected at both ends to a first main beam 22 and a second main beam 23, the second auxiliary beam 29 is fixedly connected at both ends to a second main beam 23 and a third main beam 24, the third auxiliary beam 30 is fixedly connected at both ends to a third main beam 24 and a fourth main beam 25, and the fourth auxiliary beam 31 is fixedly connected at both ends to a fourth main beam 25 and a first main beam 22. The auxiliary beams 28, 29, 30, and 31 form a rectangular frame outline.

[0042] The auxiliary beam assembly further includes a pair of short-side support auxiliary beams, each pair comprising a first support auxiliary beam 32 and a second support auxiliary beam 33. The inner ends of both the first and second support auxiliary beams 32 and 33 are fixed to the center of the tooling body. The outer ends of both the first and second support auxiliary beams 32 and 33 are fixedly connected to the auxiliary beam closest to the center of the tooling body. Furthermore, the centerlines of the first and second support auxiliary beams 32 and 33 are on the same straight line. Figure 4 As shown.

[0043] In addition, a pair of long-side supporting auxiliary beams can be added to the above structure to further improve the overall load-bearing capacity of the transfer and hoisting fixture 200. The pair of long-side supporting auxiliary beams includes a third supporting auxiliary beam 34 and a fourth supporting auxiliary beam 35. The inner ends of the third supporting auxiliary beam 34 and the fourth supporting auxiliary beam 35 are fixed to the middle of the fixture body. The outer ends of the third supporting auxiliary beam 34 and the fourth supporting auxiliary beam 35 are fixedly connected to the auxiliary beam furthest from the middle of the fixture body. Furthermore, the center lines of the third supporting auxiliary beam 34 and the fourth supporting auxiliary beam 35 are on the same straight line. Figure 5 As shown.

[0044] Before transferring coke can 4, the external coke can lifting frame 5 needs to be removed. Then, the transfer hoisting fixture 200 is placed at the mouth of coke can 4. At this time, the rope slots 27 at the ends of the four main beams all extend beyond the mouth of coke can 4. The hoisting rope 26 passes through the rope slots 27 and reaches the lifting point at the bottom of the coke can. When the crane hook 20 lifts the hoisting rope 26, the transfer hoisting fixture 200 will automatically adjust to the center position. At this time, the hoisting rope will not contact the mouth of coke can 4, which can effectively protect coke can 4.

[0045] The test hoisting fixture 100 and the transfer hoisting fixture 200 can be made of common steel materials available in the factory. The overall structure is simple, easy to manufacture, low in cost, and very convenient to use. They are also very practical and can be used for hoisting similar or different types of products that are large in size and heavy in weight, making them widely applicable.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any modifications or equivalent changes made based on the technical essence of the present utility model shall still fall within the scope of protection claimed by the present utility model.
