Description

Technical Field

[0001] This utility model relates to the technical field of horizontal hoisting mechanisms, and in particular to a horizontal hoisting mechanism for casting sand boxes. Background Technology

[0002] Sand casting is a casting method that produces castings in sand molds. Steel, iron, and most non-ferrous alloy castings can be obtained using sand casting. Because the molding materials used in sand casting are inexpensive and readily available, and the mold making is simple, it is suitable for single-piece production, batch production, and mass production of castings, and has long been a basic process in casting production.

[0003] Currently, in the production of casting sand boxes, a horizontal hoisting mechanism is needed to hoist the sand boxes. The most common hoisting mechanism is the lifting drum, which moves along the crossbeam via a traveling mechanism, thereby moving the lifting drum, and then hoisting the sand boxes.

[0004] However, most of the above-mentioned hoisting drums are hoisted using wire ropes. However, due to the lack of a limiting mechanism during the winding and unwinding of the wire rope, the wire rope is prone to coming off the groove and becoming tangled, which affects normal use. Therefore, we propose a horizontal hoisting mechanism for casting sand boxes. Utility Model Content

[0005] The purpose of this utility model is to provide a horizontal hoisting mechanism for casting sand boxes. By setting a limiting mechanism, the limiting roller can be used to limit the wire rope. At the same time, the limiting mechanism is installed in conjunction with the fixing component and the telescopic component, and the position of the limiting roller is adjusted by the adjusting component.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a horizontal hoisting mechanism for casting sand boxes, comprising a crossbeam, a traveling mechanism located below the crossbeam, and a wire rope lifting drum fixedly installed below the traveling mechanism. A limit mechanism is provided on one side of the wire rope lifting drum, the limit mechanism comprising:

[0007] A fixing plate is located on the side of the wire rope lifting drum, and a cavity is provided inside the fixing plate that penetrates one side of the fixing plate.

[0008] The telescopic assembly is disposed inside the cavity. Both ends of the telescopic assembly are fixedly connected to the fixing components, and the telescopic assembly is used to drive the fixing components to move. The fixing plate is connected to the wire rope lifting drum through the fixing components.

[0009] A limiting roller is located outside the fixed plate and is used to limit the wire rope on the wire rope lifting drum.

[0010] An adjustment component is disposed between the limiting roller and the fixed plate, and the adjustment component is used to adjust the position of the limiting roller.

[0011] Preferably, the telescopic component includes:

[0012] Rotating wheel;

[0013] Rotating threaded rods are fixedly connected to both sides of the rotating wheel, and the rotating threaded rods are rotatably connected to the cavity;

[0014] A movable block is threadedly connected to the outer surface of a rotating threaded rod, and a movable rod is fixedly connected to one end of the movable block.

[0015] Preferably, the fixing component includes:

[0016] An insert block is fixedly connected to one end of a movable rod, and the cross-sectional profile of the insert block is U-shaped.

[0017] A fixed threaded rod is threadedly connected to one side of the insert block, and a fixed round block is fixedly connected to one end of the fixed threaded rod;

[0018] A fixed clamping plate is rotatably connected to the other end of a fixed threaded rod.

[0019] Preferably, the adjustment component includes:

[0020] An annular groove is formed in the middle of the rotating wheel;

[0021] The U-shaped block is inserted into the inside of the annular groove and is fixedly connected to the limiting roller;

[0022] An adjusting threaded rod is rotatably connected to the middle of a U-shaped block, and an adjusting round block is fixedly connected to one end of the adjusting threaded rod.

[0023] Preferably, slots are provided on both sides of the cavity, and the inside of the slots is slidably connected to the moving rod.

[0024] Preferably, the outer surface of the fixing plate is provided with a through groove, and one side of the rotating wheel extends to the outside of the through groove.

[0025] The technical effects and advantages of this utility model are as follows:

[0026] The telescopic component moves the fixed component, aligning it with the edge of the wire rope hoisting drum. The fixed component is then connected to the wire rope hoisting drum to secure the limiting mechanism. Subsequently, the position of the limiting roller is adjusted using the adjusting component. The limiting roller then limits the wire rope, preventing it from slipping off the groove and becoming tangled. This design not only limits the wire rope but also allows for easy installation without altering the existing structure of the wire rope hoisting drum. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] This utility model provides, for example Figure 1-3 The image shows a horizontal hoisting mechanism for casting sand boxes. Example

[0033] The device includes a crossbeam 1, a traveling mechanism 2 located below the crossbeam 1, and a wire rope lifting drum 3 fixedly installed below the traveling mechanism 2. A limit mechanism is provided on one side of the wire rope lifting drum 3. The limit mechanism includes: a fixed plate 4 located on the side of the wire rope lifting drum 3, with a cavity penetrating one side of the fixed plate 4; a telescopic assembly 5 located inside the cavity, with fixed assemblies 6 fixedly connected to both ends of the telescopic assembly 5, and the telescopic assembly 5 used to move the fixed assemblies 6; the fixed plate 4 connected to the wire rope lifting drum 3 via the fixed assemblies 6; a limiting roller 8 located outside the fixed plate 4, used to limit the wire rope on the wire rope lifting drum 3; and an adjusting assembly 7. The limiting roller 8 is positioned between the limiting roller 8 and the fixed plate 4, and the adjusting component 7 is used to adjust the position of the limiting roller 8. The telescopic component 5 drives the fixed component 6 to move, so that the fixed component 6 is aligned with the edge of the wire rope lifting drum 3. Then, the fixed component 6 is connected to the wire rope lifting drum 3 to fix the limiting mechanism. Subsequently, the position of the limiting roller 8 is adjusted by the adjusting component 7. The limiting roller 8 plays a limiting role for the wire rope, preventing the wire rope from derailing and becoming tangled. This design can not only limit the wire rope, but also achieve smooth installation without changing the structure of the existing wire rope lifting drum 3. During hoisting, the hoisting components connected by the wire rope, such as hooks, can be used to connect the sand box, and then the wire rope lifting drum 3 can be used to wind and lift it.

[0034] Furthermore, the telescopic component 5 includes: a rotating wheel 501; a rotating threaded rod 502, with rotating threaded rods 502 fixedly connected to both sides of the rotating wheel 501, and the rotating threaded rods 502 rotatably connected to the cavity; and a moving block 503, which is threadedly connected to the outer surface of the rotating threaded rod 502, with a moving rod 504 fixedly connected to one end of the moving block 503. By rotating the rotating wheel 501, the rotating threaded rod 502 is driven to rotate. Since the moving block 503 is mutually limited by the cavity, it will not rotate. The rotating threaded rod 502 will drive the moving block 503 to move, thereby driving the moving rod 504 to move, and thus driving the fixed component 6 to move. The two rotating threaded rods 502 are reverse threads, causing the two moving blocks 503 to move closer or further apart.

[0035] Furthermore, the fixing component 6 includes: a plug 601, which is fixedly connected to one end of the moving rod 504, and the cross-sectional profile of the plug 601 is U-shaped; a fixing threaded rod 602, which is threadedly connected to one side of the plug 601, and a fixing round block 603 is fixedly connected to one end of the fixing threaded rod 602; and a fixing clamping plate 604, which is rotatably connected to the other end of the fixing threaded rod 602; the fixing component 6 is moved by the telescopic component 5 until the plug 601 is in contact with the steel wire. Align the edges of the rope lifting drum 3, then insert the plug 601 into the edge, and then move the telescopic component 5 to move the fixing component 6 so that the inner side of the plug 601 is in close contact with the inner side of the edge. Then rotate the fixing block 603 to make the fixing threaded rod 602 rotate. Because the fixing clamp 604 abuts against the inside of the plug 601, the fixing clamp 604 will not rotate, thus making the fixing clamp 604 press tightly against the edge of the wire rope lifting drum 3, thereby realizing the installation of the limiting mechanism.

[0036] Furthermore, the adjusting assembly 7 includes: an annular groove 701, which is formed in the middle of the rotating wheel 501; a U-shaped block 702, which is inserted into the annular groove 701 and is fixedly connected to the limiting roller 8; and an adjusting threaded rod 703, which is rotatably connected to the middle of the U-shaped block 702, with an adjusting round block 704 fixedly connected to one end of the adjusting threaded rod 703. By rotating the adjusting round block 704, the adjusting threaded rod 703 is rotated, which in turn causes the U-shaped block 702 to translate, thereby causing the limiting roller 8 to move and thus changing the distance between the limiting roller 8 and the wire rope. Example

[0037] Example 2 further discloses that, based on Example 1, slots are provided on both sides of the cavity, and the inside of the slots is slidably connected to the moving rod 504; this facilitates the use of the slots to limit the movement of the moving rod 504, thereby preventing the moving rod 504 from rotating.

[0038] Furthermore, a through groove is provided on the outer surface of the fixing plate 4, and one side of the rotating wheel 501 extends to the outside of the through groove; this facilitates the exposure of the rotating wheel 501, thereby making it easier to rotate the rotating wheel 501.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
