Description

Technical Field

[0001] This utility model relates to the field of crystal brick hoisting technology, specifically to a modular spinel brick hoisting clamp. Background Technology

[0002] Spinel bricks are an important refractory material, with spinel as their main mineral component. In the field of refractory materials, the most common spinel bricks refer to refractory bricks with magnesium aluminum spinel as the main component. Its core advantages are its excellent thermal shock resistance and good resistance to alkaline erosion, while also having high refractoriness, high temperature strength, and environmental friendliness (chromium-free). During the production of spinel bricks, they need to be hoisted, and hoisting clamps are required when hoisting spinel bricks.

[0003] The Chinese utility model patent with authorization announcement number "CN214780256U" is specifically a "furnace door lining brick hoisting clamp device", which includes a scissor arc plate, a clamping plate and a support plate; one end of the scissor arc plate is connected to the hoisting rope of the crane boom; the other end of the scissor arc plate is fixedly connected to the upper outer wall of the clamping plate, and the lower end of the clamping plate is vertically fixedly connected to the support plate.

[0004] Although the above-mentioned device can lift and clamp the bricks, due to the high brittleness and smooth surface of spinel bricks, and the lack of protective structure for the bricks during the lifting process, the edges of the bricks are easily damaged when they collide during lifting, which affects the precision and aesthetics of the spinel bricks. Therefore, we propose a modular spinel brick lifting clamp. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a modular spinel brick lifting fixture, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a modular spinel brick lifting clamp, including: A rectangular shell, with movable rectangular plates on both sides, and a clamping plate movably connected to the two rectangular plates on the side away from each other. A wheel frame is fixedly connected to the top of the rectangular shell, and ropes are provided on the side of the two clamping plates near the wheel frame. The anti-collision mechanism includes a U-shaped strip fixedly connected to the outside of the clamping plate, a rotatable storage shell provided on the inner side of the U-shaped strip, an adjusting plate slidably connected to the inner side of the storage shell, and a baffle fixedly connected to the other side of the adjusting plate. The protective mechanism includes two internally threaded tubes symmetrically arranged on opposite sides of the two clamping plates. The internally threaded tubes are threaded with threaded rods, and the bottom ends of the threaded rods are fixedly connected to a base plate.

[0007] Preferably, the inner side of the U-shaped strip is movably connected to a rotating shaft via a bearing, and the storage shell is fixedly connected to the outer side of the rotating shaft.

[0008] Preferably, the outer side of the housing has a through threaded hole, and a limit bolt is threadedly connected to the inner side of the threaded hole. The limit bolt passes through the threaded hole and fits tightly against the outer side of the adjustment plate.

[0009] Preferably, rubber pads are fixedly connected to the opposite surfaces of the two clamping plates.

[0010] Preferably, each of the two clamping plates is fixedly connected to a fixing block on the side furthest from each other, and the internally threaded tube is movably connected to the bottom of the fixing block via a bearing.

[0011] Preferably, a rubber block is fixedly connected to the top of the base plate.

[0012] Preferably, a limiting hole is provided on the outer side of the rectangular shell, an adjusting bolt is provided on the inner side of the limiting hole, and circular holes are provided on the outer side of the rectangular plate in a straight line with equal spacing.

[0013] The technical solution provided by this utility model has the following advantages compared with the known prior art: 1. This utility model, through the setting of the anti-collision mechanism, can clamp the spinel brick under the action of two clamping plates when hoisting it. After clamping, the baffles on both sides are rotated until the four corners of the spinel brick are protected under the action of the baffles, so as to avoid damage to the spinel brick due to collision during hoisting and improve the safety of spinel brick hoisting.

[0014] 2. By setting up a protective mechanism, this utility model allows the bottom plates on both sides to rotate after the spinel brick is lifted, so that the two bottom plates rotate to be below the spinel brick and support it from below. This ensures that the spinel brick is stable during lifting and prevents it from colliding with the ground when it comes into contact with the ground after lifting, thus further improving the protection effect of the spinel brick.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The present invention will be further described below with reference to the embodiments. Example 1:

[0020] Reference Figure 1-5 This is the first embodiment of the present invention, which discloses a modular spinel brick lifting fixture, comprising: A rectangular shell 1 has movable rectangular plates 5 on both sides. The two rectangular plates 5 are movably connected to a clamping plate 4 on the side away from each other. A wheel frame 2 is fixedly connected to the top of the rectangular shell 1. A rope 3 is provided on the side of the two clamping plates 4 near the wheel frame 2. A lifting ring is installed at the other end of the rope 3 for easy connection with lifting equipment. Two symmetrically distributed guide wheels are movably connected to the inner side of the wheel frame 2 via bearings; The clamping plate 4 is curved in shape and has an installation hole at the top. A hanging ring is provided inside the installation hole, and the rope 3 is fixedly connected to the inside of the hanging ring to facilitate the hoisting of the clamp. During hoisting, the spinel brick is clamped by lever principle.

[0021] The rectangular shell 1, rectangular plate, wheel frame 2, and rope 3 are all modularly designed to facilitate replacement if any one of the components is damaged.

[0022] A limiting hole is provided on the outer side of the rectangular shell 1, and an adjusting bolt is provided on the inner side of the limiting hole. Circular holes with equal spacing in a straight line are provided on the outer side of the rectangular plate 5.

[0023] The distance between the two clamping plates 4 can be adjusted by the rectangular shell 1 and the rectangular plate 5. After adjustment, the position of the rectangular plate 5 inside the rectangular shell 1 is limited by the adjusting bolt, so that the clamp can clamp spinel bricks of different sizes, which has good applicability and meets different hoisting needs.

[0024] The anti-collision mechanism 6 includes a U-shaped strip 605 fixedly connected to the outside of the clamping plate 4, a rotatable storage shell 606 provided on the inside of the U-shaped strip 605, an adjusting plate 602 slidably connected to the inside of the storage shell 606, and a baffle 601 fixedly connected to the other side of the adjusting plate 602. Two U-shaped strips 605 are provided, and the two U-shaped strips 605 are symmetrically distributed on both sides of the clamping plate 4; The position of the baffle 601 can be adjusted by the storage shell 606 and the adjustment plate 602. When hoisting spinel bricks, the position of the baffle 601 can be adjusted according to the size of the spinel bricks. With the help of the rectangular shell 1 and the rectangular plate 5, the hoisting fixture can hoist spinel bricks of different sizes and protect them during hoisting.

[0025] Specifically, a rotating shaft 607 is movably connected to the inner side of the U-shaped strip 605 via a bearing, and a housing 606 is fixedly connected to the outer side of the rotating shaft 607.

[0026] Under the action of the bearing, the rotating shaft 607 can rotate within the U-shaped strip 605, thereby facilitating the rotation of the storage shell 606 and adjusting the direction of the baffle 601 so that it rotates to the edge of the spinel brick. In conjunction with the adjusting plate 602, the edge of the spinel brick is protected.

[0027] Specifically, the outer side of the housing 606 has a through threaded hole 608, and the inner side of the threaded hole 608 is threaded with a limit bolt 604. The limit bolt 604 passes through the threaded hole 608 and fits tightly against the outer side of the adjusting plate 602.

[0028] The threaded hole 608 facilitates the installation of the limiting bolt 604. When the limiting bolt 604 rotates in the threaded hole 608, it can move within the threaded hole 608. When it contacts the outside of the adjusting plate 602, it can limit the adjusting plate 602 inside the housing 606, ensuring the stability of the baffle 601 position.

[0029] Specifically, rubber pads 603 are fixedly connected to the opposite sides of the two clamping plates 4.

[0030] The rubber pad 603 prevents the clamp from directly contacting the outside of the spinel brick. The damping properties of the rubber pad 603 can absorb more than 60% of the impact energy, preventing stress waves from entering the brick body. Example 2:

[0031] Reference Figure 1-4 This is the second embodiment of the present invention, which differs from the first embodiment in that: The protective mechanism 7 includes two internally threaded tubes 703 symmetrically arranged on opposite sides of the two clamping plates 4. The internally threaded tubes 703 are threadedly connected to a threaded rod 704, and the bottom end of the threaded rod 704 is fixedly connected to a base plate 702.

[0032] The position of the base plate 702 can be adjusted by the internal threaded tube 703 and the threaded rod 704, so that the position of the base plate 702 can be adjusted according to the size of the spinel brick, making it convenient for the base plate 702 to cooperate with the rubber block 701 to support the bottom of the spinel brick.

[0033] Specifically, each of the two clamping plates is fixedly connected to a fixing block 705 on the side furthest from the other, and the internally threaded pipe 703 is movably connected to the bottom of the fixing block 705 via a bearing.

[0034] The fixing block 705 facilitates the connection between the internal threaded tube 703 and the clamping plate 4. The bearing enables the internal threaded tube 703 to rotate, so that after the spinel brick is lifted, the base plate 702 can be rotated to the bottom of the spinel brick to support it from the bottom and improve the stability of the hoisting.

[0035] Specifically, a rubber block 701 is fixedly connected to the top of the base plate 702.

[0036] The rubber block 701 prevents the spinel brick from directly contacting the base plate 702, thus avoiding damage to the spinel brick.

[0037] The remaining structure is the same as that in Example 1.

[0038] The workflow of this utility model is as follows: Depending on the size of the spinel brick to be hoisted, the distance between the two clamping plates 4 is adjusted. When adjusting the distance between the two clamping plates 4, rotate the adjusting bolt to move it out of the round hole. At this time, the distance between the two clamping plates 4 can be adjusted until the distance between the two clamping plates 4 is slightly larger than the spinel brick. After the adjustment is completed, rotate the adjusting bolt in the opposite direction to limit the position of the rectangular plate 5 inside the rectangular shell 1. When hoisting the spinel brick, position the spinel brick between the two clamping plates 4, and rotate the four baffles 601 on the outside of the clamping plates 4 so that they are positioned at the corners of the spinel brick to protect the corners. The hoisting equipment moves the rope 3 upward by pulling the hoisting ring. Under the action of the guide wheel, it can pull the top of the two clamping plates 4 to move away from each other. Under the action of the rectangular plate 5, the two clamping plates 4 clamp the spinel brick in the middle. When the spinel brick is hoisted to a certain height, the base plates 702 on both sides are rotated so that the base plates 702 support the spinel brick from the bottom.

[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
