Description

Technical Field

[0001] The utility model relates to the technical field of magnesia carbon brick handling equipment, in particular to a magnesia carbon brick handling fixture. Background Art

[0002] Magnesium carbon bricks are a kind of refractory material. Because of their good high temperature resistance, strong slag resistance, good thermal shock resistance, low high temperature creep and other characteristics, they are often used in the lining of converters, AC arc furnaces, DC arc furnaces, slag lines of ladles and other parts. Magnesium carbon bricks need to be transported by clamps after burning. For most magnesium carbon bricks with regular structural shapes, the existing clamps can basically complete the handling operation; for some special structures or customized magnesium carbon bricks, they are usually polygonal structures with multiple through holes running through the length direction, and grooves are arranged at intervals on the surface. This type of magnesium carbon brick is lifted by ordinary brick clamps, but there is an unstable clamping situation, which can easily cause the bricks to fall during the transfer process, posing a safety hazard. Therefore, there is an urgent need for a clamp that can meet the handling of special-shaped magnesium carbon bricks. Utility Model Content

[0018] The following is a clear and complete description of the present invention in conjunction with the accompanying drawings and embodiments:

[0019] like Figure 1 to Figure 2As shown, a magnesium carbon brick handling clamp described in the utility model includes a support part 1, and clamping plates 2 are arranged at both ends of the support part 1, one of the clamping plates 2 is hinged to the support part 1, and a lifting part 4 is arranged on the clamping plate 2, and the lifting part 4 is located above the support part 1 and is arranged along the length extension direction of the support part 1; at least a supporting rod 3 is arranged on the clamping plate 2 provided with the lifting part 4, and the supporting rod 3 can be adjusted to a state parallel or perpendicular to the clamping plate 2. When carrying irregular magnesium carbon bricks, the support rod 3 can be adjusted to be perpendicular to the clamping plate 2, and the support rod 3 can be inserted into the through hole opened in the side wall of the magnesium carbon brick. When the weight of the magnesium carbon brick is relatively small, only the support rod 3 can be inserted into the through hole of the magnesium carbon brick, and then the lifting part 4 is pulled to complete the transportation; when the weight of the magnesium carbon brick is slightly larger, the support rod 3 can be inserted into the through hole of the magnesium carbon brick, and the two clamping plates 2 are respectively clamped on the two side walls of the magnesium carbon brick, and then the lifting part 4 is pulled. At this time, the transportation operation of the magnesium carbon brick is realized with the cooperation of the two clamping plates 2 and the support rod 3. By passing the support rod 3 through the through hole of the magnesium carbon brick, the magnesium carbon brick can be provided with lifting support, avoiding the situation where the brick falls due to the loose clamping of the clamping plate 2, and effectively ensuring safety.

[0020] Preferably, both clamping plates 2 are provided with supporting rods 3, which can be used for the handling operation of magnesium-carbon bricks with heavy weight. By inserting the supporting rods 3 on both sides through the through holes on both sides of the magnesium-carbon bricks, the magnesium-carbon bricks can be provided with stable lifting support, further ensuring the safety during the handling process. When supporting rods 3 are provided on both sides of the clamping plates 2, the length of the supporting rods 3 on each side does not need to be too long, as long as it can be ensured to be able to penetrate into the through holes of the magnesium-carbon bricks to provide support for them, which can save costs and facilitate clamping and use; the number of supporting rods 3 on each clamping plate 2 can be set according to actual needs, and one can be set centrally on the clamping plate 2, or two can be set separately. When only one supporting rod 3 is set, its diameter and bearing capacity need to be appropriately increased. Since one supporting rod 3 is more flexible when in use, it is preferred to set a single supporting rod 3 on the clamping plate 2. In addition, in this embodiment, when the support rod 3 is adjusted to a state parallel to the clamping plate 2, it does not protrude from the inner side surface of the clamping plate 2, so as to ensure that when regular bricks are clamped, the end surface of the clamping plate 2 in contact with the brick is flat, thereby ensuring close contact between the clamping plate 2 and the side wall of the brick, thereby improving the stability of the brick during transportation.

[0021] Specifically, a through slot 5 is provided through the clamping plate 2, and the support rod 3 is adjustably arranged at the through slot 5 on the outside of the clamping plate 2; when the support rod 3 is needed, the support rod 3 is adjusted to pass through the through slot 5 and be in a vertical state with the clamping plate 2; further, a rotating support sleeve 6 is provided on both sides of the through slot 5 on the outside of the clamping plate 2, and a rotating rod 7 is vertically provided at the top of the support rod 3, and the rotating rod 7 is rotated and located in the rotating support sleeve 6, and a positioning member is provided between one of the rotating support sleeves 6 and the rotating rod 7. The positioning member is used to position the support rod 3 after the state is adjusted to ensure its stability during use; preferably, the positioning member includes a positioning sleeve 8, which is movably arranged on one side of the rotating support sleeve 6, and the positioning sleeve 8 can only be movably adjusted along the axial direction of the rotating support sleeve 6 to realize the separation operation between it and the rotating support sleeve 6, and a cross-shaped positioning head 9 is provided in the positioning sleeve 8, and a cross-shaped positioning groove is provided at the end of the rotating rod 7. In the initial state, the cross-shaped positioning head 9 is located in the cross-shaped positioning groove, and the positioning sleeve 8 is in close contact with the rotating support sleeve 6; when the support rod 3 needs to be adjusted, the positioning sleeve 8 is pulled to move along the axial direction of the rotating support sleeve 6 to separate it from the rotating support sleeve 6, and the cross-shaped positioning head 9 is disengaged from the cross-shaped positioning groove, and the support rod 3 is released from its positioning. At this time, the support rod 3 can be rotated 90 degrees, and then the positioning sleeve 8 is reset to allow the cross-shaped positioning head 9 to enter the cross-shaped positioning groove, and the support rod 3 is positioned again.

[0022] Furthermore, in this embodiment, the positioning sleeve 8 is elastically connected to the rotating support sleeve 6, and in the initial state, the positioning sleeve 8 is in close contact with the rotating support sleeve 6. Specifically, a positioning rod 10 is provided on the side wall of the positioning sleeve 8 along its axial direction, and a positioning hole 11 is provided at a corresponding position on the rotating support sleeve 6. A spring is provided in the positioning hole 11, and the spring is connected to the positioning rod 10; the provision of the spring helps the automatic reset of the positioning sleeve 8, and at the same time ensures the close contact between the positioning sleeve 8 and the rotating support sleeve. In the initial state of the spring, the positioning sleeve 8 is in close contact with the rotating support sleeve 6.

[0023] Furthermore, in the present embodiment, the lengths of the supporting portion 1 and the lifting portion 4 are adjustable to meet the needs of bricks of different sizes; the specific supporting portion 1 includes an external sleeve 1-1, an adjusting rod 1-2 is slidably arranged inside the sleeve 1-1, and an external thread of the sleeve 1-1 is provided with a first locking bolt, and the first locking bolt is used to tighten and fix the adjusted adjusting rod 1-2 to ensure the stability of its position; the lifting portion 4 includes a lifting rod 4-1 fixedly connected to the clamping plate 2, a lifting sleeve 4-2 is movably sleeved on the outside of the lifting rod 4-1, and a second locking bolt is provided at the end of the lifting sleeve 4-2, and the second locking bolt is used to fix the lifting sleeve 4-2 to the lifting rod 4-1; in the present embodiment, the sleeve 1-1 and the lifting sleeve 4-2 are preferably arranged as cylindrical structures for easy hand holding.

[0024] In this embodiment, the clamping plate 2 without the lifting part 4 is movably connected to the support part 1, and the clamping plate 2 can be adjusted to a state perpendicular or parallel to the support part 1. This situation is used in the case where the weight of the magnesium carbon brick is small. At this time, it is only necessary to insert a single support rod 3 into the through hole of the magnesium carbon brick, and pull the lifting part 4 to realize the transportation of the magnesium carbon brick. There is no need for the intervention of the clamping plate 2 and the support rod 3 at the other end. By adjusting the clamping plate 2 away from the lifting part 4 to a state horizontal with the lifting part 4, it is convenient to use a single support rod 3, and the efficiency of magnesium carbon brick transportation is also improved. Specifically, the clamping plate 2 at this end is symmetrically provided with mounting protrusions 12, and the end of the lifting part 4 is located between the two mounting protrusions 12, and is detachably connected to the mounting protrusion 12 by bolts.

[0025] When the utility model is in use, when the weight of the magnesium carbon brick is relatively small, only a single support rod 3 can be used for hooking and transporting as described above; when the weight of the magnesium carbon brick is relatively large, the two support rods 3 can be adjusted, and the two support rods 3 can be inserted into the through holes of the magnesium carbon brick, and then the side walls of the magnesium carbon brick can be clamped by the clamping plate 2, and the transport operation can be achieved by pulling the lifting part 4; when it is necessary to transport regular rectangular bricks, the support rods 3 on both sides can be retracted, and only the clamping plate 2 can be used for clamping; the structure is simple, the functions are rich, and the practicability is strong.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein with equivalents.
