Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of clamps, in particular to a clamp for cleaning cargo boxes with a grab bucket of an excavator. Background Art
[0002] Excavator grab buckets can be divided into shell-shaped grab buckets according to their shape. They are composed of two complete bucket-shaped components. During use, the materials are grabbed by closing the two grab buckets. They are often used for material loading and unloading operations in cargo boxes of ships, trains, cars, etc.
[0003] In the prior art, after the materials in the cargo box of a train are grabbed by the grab bucket of an excavator, a lot of materials will remain in the cargo box, which cannot be grabbed by the grab bucket at one time. Manual cleaning and collection are required before the grab bucket can be used for grabbing. The manual collection speed is slow, which affects the work efficiency. Utility Model Content
[0004] The utility model provides a clamp for cleaning a cargo box of an excavator grab bucket, which can improve the problems of slow speed, labor-consuming and time-consuming manual collection of materials in the cargo box in the prior art.
[0005] The technical solution of the utility model to solve the above technical problems is as follows:
[0006] A clamp for cleaning a cargo box with an excavator grab bucket comprises a clamping plate which is vertically arranged and used to be clamped by the grab bucket, a connecting piece which is horizontally arranged and fixedly connected at one end to the lower end of the clamping plate, and a scraper which is vertically arranged and fixedly connected at the upper end to the other end of the connecting piece, wherein the clamping plate and the scraper are respectively located at the upper and lower sides of the connecting piece.
[0007] The beneficial effect of the utility model is that when in use, the clamping plate is clamped on the grab bucket, at which time the scraper extends downward away from the grab bucket, and then the excavator is started, and the swing of the grab bucket drives the scraper plate to swing, so that the scraper plate scrapes the materials in the cargo box together to concentrate the materials, making it easier for the grab bucket to grab them out of the box, thereby improving the problem of slow speed, labor-consuming and time-consuming manual collection of materials in the cargo box in the prior art.
[0008] On the basis of the above technical solution, the present invention can also be improved as follows.
[0009] Furthermore, at least one end of the scraper in the horizontal direction is connected to an extension plate, and the lower side of the extension plate and the lower side of the scraper are on the same plane.
[0010] The beneficial effect of adopting the above further scheme is that in the process of scraping the material by swinging the scraper, the extension plate can be used to scrape the material on the side walls and corners of the cargo box to ensure the scraping range.
[0011] Furthermore, at least one end of the scraper in the horizontal direction is fixedly connected to a rotating seat, the extension plate is rotatably connected to the rotating seat, and the rotating seat sleeve is provided with a torsion spring, and both ends of the torsion spring are respectively fixedly connected to the extension plate and the rotating seat.
[0012] The beneficial effect of adopting the above further scheme is: the connection between the extension plate and the scraper is ensured by the torsion spring. At the same time, the torsion force of the torsion spring can form a buffering effect when the swinging extension plate touches the side wall of the cargo box, and the hanging of materials is completed as the extension plate swings.
[0013] Furthermore, the rotating seat includes two fixed blocks fixedly connected to the scraper and a rotating shaft with two ends respectively fixedly connected to the two fixed blocks, the extension plate is rotatably connected to the rotating shaft, and the torsion spring is sleeved on the rotating shaft.
[0014] The beneficial effect of adopting the above further solution is that a mounting base for the extension plate and the torsion spring is formed by the fixing block and the rotating shaft to ensure smooth rotation of the extension plate.
[0015] Furthermore, the elastic force of the torsion spring can drive the extension plate to rotate and form an obtuse angle structure with the scraper plate that opens toward the clamping plate.
[0016] The beneficial effect of adopting the above further solution is that an obtuse angle is formed between the extension plate and the scraper plate, so that the material scraped by the extension plate can be guided by the extension plate to the scraper plate and quickly gathered.
[0017] Furthermore, the scraper plate is an arc-shaped plate, and the middle portion thereof protrudes in a direction away from the clamping plate.
[0018] The beneficial effect of adopting the above further solution is that in the process of using the scraper to scrape the material, the scraper is used to form a centralized guiding effect on the material to achieve rapid concentration.
[0019] Furthermore, one end of the connecting piece connected to the clamping plate is in an arc-shaped structure and protrudes downward.
[0020] The beneficial effect of adopting the above further solution is that when the clamping plate is clamped on the grab bucket, the connecting piece can better abut against the lower side of the grab bucket, so that the grab bucket can provide support for the connecting piece.
[0021] Furthermore, the connecting member includes at least one arc-shaped plate, and the arc-shaped plate protrudes downward.
[0022] The beneficial effect of adopting the above further solution is: the contact area with the lower side of the grab bucket is increased by the arc plate, and the connection between the clamping plate and the scraper is achieved.
[0023] Furthermore, the connecting member includes a fixed plate fixedly connected to the upper end of the scraper, a screw rod one end of which is rotatably connected to the fixed plate, and at least one guide rod one end of which is fixedly connected to the fixed plate, the other end of the screw rod is threadedly connected to the lower end of the clamping plate, and the other end of each guide rod is slidably connected to the lower end of the clamping plate.
[0024] The beneficial effect of adopting the above further scheme is that by fixing the clamping plate and rotating the other end of the screw, the fixed plate and the scraper can be moved relative to the clamping plate under the guiding and limiting action of the guide rod, so that the distance between the scraper and the clamping plate is greater than the depth of the grab, and the scraper is located outside the grab to ensure that the grab will not hinder the scraping of the scraper.
[0025] Furthermore, the upper end of the clamping plate is slidably connected to a plurality of hanging rods, and the length direction of the hanging rods extends along the thickness direction of the clamping plate.
[0026] The beneficial effect of adopting the above further solution is that when the clamping plate is clamped in the grab bucket, the hanging rod is hung in the grab bucket, and both ends are supported by the grab bucket, which can improve the clamping stability of the clamp.

[0032] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.
[0033] First of all, it should be noted that in the prior art, a shell-shaped grab includes two bucket shells, the bottoms of which abut against each other to grab the material. The bottom of the bucket shell is usually an arc-shaped structure, so that when the grab is closed, the arc-shaped bottom can guide the material to gather toward the center, wrap the object more tightly, and improve the grabbing efficiency and stability; and when it is opened, it helps to discharge the material smoothly and reduce residue.
[0034] Example 1
[0035] like Figure 1 and Figure 2 A clamp for cleaning a cargo box with an excavator grab bucket comprises a clamping plate 1 which is vertically arranged and used to be clamped by the grab bucket, a connecting member 2 which is horizontally arranged and fixedly connected at one end to the lower end of the clamping plate 1, and a scraper 3 which is vertically arranged and fixedly connected at the upper end to the other end of the connecting member 2. The clamping plate 1 and the scraper 3 are respectively located at the upper and lower sides of the connecting member 2.
[0036] The beneficial effects of this embodiment are:
[0037] As a parallel solution of the above-mentioned embodiment, when in use, the clamping plate 1 is clamped on the grab bucket. At this time, the scraper 3 extends downward away from the grab bucket, and then the excavator is started. The swing of the grab bucket drives the scraper 3 to swing, so that the scraper 3 scrapes the materials in the cargo box together to concentrate the materials, making it easier for the grab bucket to grab them out of the box, thereby improving the problem of slow speed, labor-consuming and time-consuming manual collection of materials in the cargo box in the prior art.
[0038] The entire fixture has a simple structure, is easy to manufacture and use on site, and has low cost.
[0039] It should be noted that, during the manufacturing process, the size of the connecting piece 2 can be made larger than the size of one of the bucket shells of the grab (i.e., the projection surface of the entire clamp on the horizontal plane), and the projection surface of the entire clamp on the horizontal plane includes the projection surface of one of the bucket shells of the grab on the horizontal plane, so that the scraper 3 can extend beyond the projection surface of one of the bucket shells of the grab, and the two ends of the scraper 3 in the length direction are located outside the projection surface of one of the bucket shells of the grab, so as to ensure that the scraper 3 can smoothly hang the material without being hindered by the swinging grab, causing collision between the grab and the cargo box.
[0040] As a specific solution of the above embodiment, the clamping plate 1 can be a whole plate structure, or a multi-rod structure.
[0041] The clamping plate 1 and the scraper 3 can be supported by steel plates or hard rubber materials.
[0042] Based on the above embodiment, a buffer plate (not shown in the figure) is fixed to the side of the scraper 3 facing away from the clamping plate 1. The buffer plate can be made of rubber to prevent the scraper 3 from colliding with the inner wall of the cargo box and being damaged, and to reduce collision noise.
[0043] Example 2
[0044] like Figure 1 and Figure 2 On the basis of Example 1, at least one end of the scraper 3 in the horizontal direction is connected to an extension plate 4, and the lower side of the extension plate 4 and the lower side of the scraper 3 are on the same plane.
[0045] The beneficial effect of adopting the preferred solution in the above embodiment is that, in the process of scraping the material by swinging the scraper 3, the extension plate 4 can be used to scrape the material on the side walls and corners of the cargo box to ensure the scraping range.
[0046] The extension plate 4 can be made of steel plate or rubber material. The extension plate 4 is located outside the vertical projection plane of the clamping plate 1 and the connecting piece 2 to ensure that the extension plate 4 can scrape the materials on the side wall and corner of the cargo box without being limited or blocked by the clamping plate 1 and / or the connecting piece 2.
[0047] It should be noted that, during manufacturing, the extension plate 4 is made to extend out of the grab bucket.
[0048] Example 3
[0049] like Figure 1 and Figure 2 On the basis of embodiments 1 and 2, at least one end of the scraper 3 in the horizontal direction is fixedly connected to a rotating seat 5, the extension plate 4 is rotatably connected to the rotating seat 5, and the rotating seat 5 is sleeved with a torsion spring 6, and the two ends of the torsion spring 6 are respectively fixedly connected to the extension plate 4 and the rotating seat 5.
[0050] The beneficial effect of adopting the preferred scheme in the above embodiment is that the connection between the extension plate 4 and the scraper 3 is ensured by the torsion spring 6. At the same time, the torsion force of the torsion spring 6 can form a buffering effect when the swinging extension plate 4 touches the side wall of the cargo box, and the hanging of materials is completed as the extension plate 4 swings.
[0051] As a parallel solution of the above embodiment, the extension plate 4 can be directly welded to the end of the scraper 3.
[0052] Example 4
[0053] like Figure 1 and Figure 2 On the basis of embodiments 1-3, the rotating seat 5 includes two fixed blocks 51 fixedly connected to the scraper 3 and a rotating shaft 52 whose two ends are respectively fixedly connected to the two fixed blocks 51, the extension plate 4 is rotatably connected to the rotating shaft 52, and the torsion spring 6 is sleeved on the rotating shaft 52.
[0054] The beneficial effect of adopting the preferred solution in the above embodiment is that the fixing block 51 and the rotating shaft 52 form a mounting base for the extension plate 4 and the torsion spring 6 to ensure smooth rotation of the extension plate 4 .
[0055] On the basis of the above embodiment, two fixed blocks 51 are arranged at intervals in the upper and lower parts, and the fixed block 51 located at the lower part is fixedly connected to the middle end of the scraper 3, forming a spacing with the lower end side of the scraper 3, so that when the scraper 3 scrapes the material, the rotating seat 5 will not have direct contact with the bottom of the cargo box, reducing damage. Furthermore, the extension plate 4 is in an "L" shape, one end of which is rotatably connected to the rotating shaft 52, and the other end extends horizontally and is located at the lower side of the fixed block 51 below, forming a protective effect on the fixed block 51 below.
[0056] Example 5
[0057] like Figure 1 and Figure 2 On the basis of embodiments 1-4, the elastic force of the torsion spring 6 can drive the extension plate 4 to rotate and form an obtuse angle structure opening toward the clamping plate 1 together with the scraper plate 3.
[0058] The beneficial effect of adopting the preferred solution in the above embodiment is that an obtuse angle is formed between the extension plate 4 and the scraper plate 3, so that the material scraped by the extension plate 4 can be guided by the extension plate 4 to the scraper plate 3 and quickly collected.
[0059] Based on the above embodiment, the extension plate 4 is an arc-shaped plate opening toward the clamping plate 1, so that when the scraper 3 scrapes the material, the extension plate 4 forms a concentrated guiding effect on the material, thereby achieving rapid concentration of the material toward the scraper 3.
[0060] Example 6
[0061] like Figure 1 and Figure 2 On the basis of embodiments 1-5, the scraper 3 is an arc-shaped plate, and the middle part protrudes in the direction away from the clamping plate.
[0062] The beneficial effect of adopting the preferred solution in the above embodiment is that, in the process of scraping the material by the scraper 3, the scraper 3 is used to form a centralized guiding effect on the material, so as to achieve rapid concentration.
[0063] Example 7
[0064] like Figure 1 and Figure 2 On the basis of embodiments 1-6, one end of the connecting member 2 connected to the clamping plate 1 is in an arc-shaped structure and protrudes downward.
[0065] The beneficial effect of adopting the preferred solution in the above embodiment is that when the clamping plate 1 is clamped in the grab bucket, the connecting member 2 can better abut against the lower side of the grab bucket, so that the connecting member 2 can be supported by the grab bucket.
[0066] Specifically, the end of the connecting member 2 close to the clamping plate 1, or the end away from the clamping plate 1, or the entire connecting member 2 (such as Figure 1 ) is an arc-shaped structure that opens upward.
[0067] Example 8
[0068] like Figure 1 and Figure 2 Based on the embodiments 1-7, the connecting member 2 includes at least one arc-shaped plate, and the arc-shaped plate protrudes downward.
[0069] The beneficial effect of adopting the preferred solution in the above embodiment is that the contact area with the lower side of the grab bucket is increased by the arc plate, and the connection between the clamping plate 1 and the scraper 3 is achieved.
[0070] As a specific solution of the above embodiment, the connecting member 2 can be one, two, three or four arc-shaped plates.
[0071] Example 9
[0072] like Figure 3 On the basis of Examples 1-6, the connecting member 2 includes a fixed plate 21 fixedly connected to the upper end of the scraper 3, a screw 22 rotatably connected to the fixed plate 21 at one end, and at least one guide rod 23 fixedly connected to the fixed plate 21 at one end, the other end of the screw 22 is threadedly connected to the lower end of the clamping plate 1, and the other end of each guide rod 23 is slidably connected to the lower end of the clamping plate 1.
[0073] The beneficial effect of adopting the preferred scheme in the above embodiment is that by fixing the clamping plate 1 and rotating the other end of the screw 22, under the guiding and limiting action of the guide rod 23, the fixed plate 21 and the scraper 3 can be moved relative to the clamping plate 1, so that the distance between the scraper 3 and the clamping plate 1 is greater than the depth of the grab, and the scraper 3 is located outside the grab to ensure that the grab will not hinder the scraping of the scraper 3.
[0074] At the same time, the two ends of the screw rod 22 and the guide rod 23 are respectively in contact with the two bucket shells of the grab bucket, so that the entire clamp is more stable during the process of scraping the material.
[0075] The number of the guide rods 23 can be one, two, three, four, etc.; in the figure, two guide rods 23 are shown, and they are respectively arranged on both sides of the screw rod 22.

[0079] The plurality of hanging rods 7 can be one, two, three, etc. In the figure, the plurality of hanging rods 7 are shown as three.
[0080] As a parallel solution, the hanging rod 7 is threadedly connected to the upper end of the clamping plate 1 .
