Description

Technical Field

[0001] This utility model relates to the field of crane traveling mechanism technology, and in particular to a wear-resistant track for crane traveling mechanism. Background Technology

[0002] Currently, cranes are commonly used to save manpower when moving heavy objects. A crane is a multi-action lifting machine that can vertically lift and horizontally move heavy objects within a certain range. It is also known as an overhead crane, gantry crane, or hoist.

[0003] Existing crane traveling mechanisms generally rely on traveling wheels to move along the crane rails to achieve the purpose of moving the crane and the goods.

[0004] The aforementioned crane rails will inevitably wear down due to prolonged use. Most existing crane rails are welded and cannot be separated, or a wear-resistant coating is applied to the rails. Therefore, we propose a wear-resistant rail for the crane traveling mechanism. Utility Model Content

[0005] The purpose of this utility model is to provide a wear-resistant track for a crane traveling mechanism. By setting a wear-resistant structure, not only can the wear-resistant plate assembly be replaced, but effective wear resistance is also provided. At the same time, there is no need to drill holes in the existing track structure, so the load-bearing capacity is not significantly reduced. In addition, the whole structure is also easy to maintain and assemble later.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wear-resistant rail for a crane traveling mechanism, comprising a rail body, wherein a wear-resistant structure is provided on the rail body, and the wear-resistant structure includes:

[0007] A wear-resistant plate assembly is disposed on the side of the track body and is used to contact the crane traveling mechanism;

[0008] A connecting plate, which is fixedly connected to one side of the wear-resistant plate assembly;

[0009] A fixed sleeve is fixedly connected to the outer surface of the track body, and an adjusting block is slidably connected inside the fixed sleeve;

[0010] A locking component is disposed between the fixed sleeve and the adjusting block, and the locking component is used to lock the position of the adjusting block;

[0011] An extrusion structure is disposed between the connecting plate and the adjusting block, and the extrusion structure is used to extrude the connecting plate;

[0012] An installation component is disposed between the extrusion structure and the connecting plate, and the installation component is used to connect the extrusion structure and the connecting plate.

[0013] Preferably, the wear-resistant plate assembly includes:

[0014] A wear-resistant layer is fixedly connected to one end of the connecting plate;

[0015] A substrate, wherein the substrate is fixedly connected to one side of the wear-resistant layer;

[0016] A padding layer is fixedly connected to one side of the substrate.

[0017] Preferably, the extrusion structure includes a slider and an extrusion assembly, the extrusion assembly comprising:

[0018] A sliding cavity is provided in the middle of the adjusting block, and the sliding cavity is convex in shape. The sliding cavity is slidably connected to the slider.

[0019] A press threaded hole is formed at the top of the slide cavity, and a press bolt is connected to the internal thread of the press threaded hole;

[0020] The top of the fixed sleeve has a through groove.

[0021] Preferably, the mounting assembly includes a mounting plate fixedly connected to one end of the slider extending to the outside of the fixed sleeve, a mounting threaded rod fixedly connected to one side of the mounting plate, and a mounting nut threadedly connected to one end of the mounting threaded rod passing through the connecting plate. A slot is provided on one side of the bottom of the fixed sleeve.

[0022] Preferably, the locking assembly includes a groove formed on one side of the top of the fixed sleeve, a locking threaded rod fixedly connected to the side of the adjusting block, and a locking nut threadedly connected to one end of the locking threaded rod passing through the groove.

[0023] Preferably, the wear-resistant layer is made of alloy steel or high-hardness steel, and the pad is made of rubber.

[0024] The technical effects and advantages of this utility model are as follows:

[0025] By connecting the wear-resistant plate assembly to the track body, and then moving the adjusting block along the fixed sleeve, the mounting assembly can be connected to the connecting plate. The mounting assembly is then used to connect the connecting plate to the extrusion structure, thus completing the initial installation of the wear-resistant plate assembly. Subsequently, the locking assembly is used to lock the position of the adjusting block, and the extrusion structure is used to extrude the connecting plate, ensuring that the wear-resistant plate assembly and the track body fit together fully, avoiding large gaps that could prevent proper load-bearing capacity. This design eliminates the need for drilling holes in the track body, preventing a significant reduction in the track body's load-bearing capacity. Furthermore, the installation method is simple, facilitating assembly and production, and the wear-resistant plate assembly exhibits excellent wear resistance. Attached Figure Description

[0030] 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.

[0031] This utility model provides, for example Figure 1-3 The image shows a wear-resistant track for a crane traveling mechanism.

[0032] Example 1

[0033] The system includes a track body 1, on which a wear-resistant structure is provided. The wear-resistant structure includes: a wear-resistant plate assembly 2, which is disposed on the side of the track body 1 and is used to contact the crane's traveling mechanism; a connecting plate 6, which is fixedly connected to one side of the wear-resistant plate assembly 2; a fixing sleeve 3, which is fixedly connected to the outer surface of the track body 1, and an adjusting block 4 is slidably connected inside the fixing sleeve 3; a locking assembly 8, which is disposed between the fixing sleeve 3 and the adjusting block 4 and is used to lock the position of the adjusting block 4; a pressing structure, which is disposed between the connecting plate 6 and the adjusting block 4 and is used to press the connecting plate 6; and an installation assembly 7, which is disposed between the pressing structure and the connecting plate 6. The mounting component 7 is used to connect the extrusion structure and the connecting plate 6. By docking the wear-resistant plate assembly 2 with the track body 1, and then moving the adjusting block 4 along the fixed sleeve 3, the mounting component 7 can dock with the connecting plate 6. Then, the mounting component 7 is used to connect the connecting plate 6 with the extrusion structure, thus completing the initial installation of the wear-resistant plate assembly 2. Subsequently, the locking component 8 is used to lock the position of the adjusting block 4, and then the extrusion structure is used to extrude the connecting plate 6, so that the wear-resistant plate assembly 2 and the track body 1 are fully fitted together, avoiding large gaps that would prevent proper load-bearing capacity. This design does not require drilling holes in the track body 1, thus avoiding a significant reduction in the load-bearing capacity of the track body 1. At the same time, the installation method is simple, facilitating assembly and production. In addition, the wear-resistant plate assembly 2 has good wear resistance.

[0034] Furthermore, the wear-resistant plate assembly 2 includes: a wear-resistant layer 202, which is fixedly connected to one end of the connecting plate 6; a base plate 201, which is fixedly connected to one side of the wear-resistant layer 202; and a pad 203, which is fixedly connected to one side of the base plate 201. The wear-resistant layer 202 contacts the crane traveling mechanism, thereby providing good wear resistance.

[0035] Furthermore, the extrusion structure includes a slider 5 and an extrusion assembly 9. The extrusion assembly 9 includes: a sliding cavity 901, which is located in the middle of the adjusting block 4 and is convex in shape, and is slidably connected to the slider 5; an extrusion threaded hole 902, which is located at the top of the sliding cavity 901, and an extrusion bolt 904 is threadedly connected inside the extrusion threaded hole 902; and a through groove 903, which is located at the top of the fixing sleeve 3. By rotating the extrusion bolt 904, the extrusion bolt 904 moves down along the extrusion threaded hole 902, thereby extruding the slider 5, causing the slider 5 to slide along the inside of the sliding cavity 901. The slider 5 drives the connecting plate 6 to move down, thereby ensuring that the wear-resistant plate assembly 2 and the track body 1 are in stable and full contact, avoiding gaps that could affect the normal operation of the crane traveling mechanism.

[0036] Furthermore, the mounting assembly 7 includes a mounting plate 701 fixedly connected to one end of the slider 5 extending to the outside of the fixed sleeve 3, a mounting threaded rod 702 fixedly connected to one side of the mounting plate 701, and a mounting nut 703 threadedly connected to one end of the mounting threaded rod 702 passing through the connecting plate 6. A slot is provided on one side of the bottom of the fixed sleeve 3; the slot is to facilitate the slider 5 to move down, pass the connecting plate 6 through the mounting threaded rod 702, and then screw the mounting nut 703 onto the mounting threaded rod 702, thus completing the connection between the connecting plate 6 and the extrusion structure.

[0037] Furthermore, the locking assembly 8 includes a groove 801 formed on one side of the top of the fixed sleeve 3, a locking threaded rod 802 fixedly connected to the side of the adjusting block 4, and a locking nut 803 threadedly connected to one end of the locking threaded rod 802 passing through the groove 801. As the adjusting block 4 moves along the inside of the fixed sleeve 3, the locking threaded rod 802 moves along the groove 801, the slider 5 moves along the groove opening, and the compression nut 904 moves along the through groove 903, thereby facilitating the movement of the adjusting block 4. Then, the locking nut 803 is screwed onto the locking threaded rod 802. This design can reduce the requirements for the fixed position of the mounting assembly 7.

[0038] Example 2

[0039] Example 2 further discloses a wear-resistant layer 202 and a pad 203 based on Example 1. The wear-resistant layer 202 is made of alloy steel or high-hardness steel, and the pad 203 is made of rubber. The wear-resistant layer 202 can also be made of other wear-resistant coating materials.

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.
