Description

Technical Field

[0001] This utility model relates to the technical field of hoisting equipment installation, and in particular to an adjustable lifting lug for a grab bucket type automatic bar screen cleaning machine. Background Technology

[0002] In a grab bucket type automatic bar screen cleaner, a winch (also known as a hoist) and a wire rope are usually provided. The wire rope is installed on the lifting lug of the grab bucket. When it is necessary to raise or lower the grab bucket, the winch unwinds the wire rope to drive the grab bucket to move along the bar screen and complete the raising or lowering.

[0003] For example, application number CN202020334159.8 discloses a lifting lug that replaces a wire rope clamp, comprising: a trunnion plate, a straight plate, an inclined plate, a tapered pin, and a wire rope; the straight plate is welded to one side of a trunnion plate; the inclined plate is welded to the other side of the trunnion plate; the trunnion plate is provided with a pin hole that mates with the pin, and the trunnion plate is fixed to the grab bucket by the pin; the tapered pin, which is larger at one end and smaller at the other, has semi-circular grooves on both sides, and the wire rope and the tapered pin are connected in the semi-circular grooves.

[0004] It mentions that during installation, the wire rope is bent and placed inside the trunnion plate along with the tapered pin; the trunnion plate has a small upper opening and a large lower opening, so the wire rope is under tension when the grab bucket is rising, and the more it is pulled, the tighter the wire rope becomes and it will not come off.

[0005] However, in actual installation, a grab bucket is usually equipped with multiple lifting lugs. In order to prevent the grab bucket from tipping over, the length of the wire rope on each lifting lug needs to be finely adjusted during installation and commissioning until the grab bucket is in a horizontal state.

[0006] Typically, the tapered pin needs to be loosened first, the wire rope length needs to be readjusted, and then it needs to be threaded back into the tapered pin; this adjustment process is cumbersome and reduces the efficiency of grab bucket installation and commissioning. Utility Model Content

[0007] In view of the above problems, this utility model provides an adjustable lifting lug for a grab bucket type automatic bar screen cleaning machine, the purpose of which is to improve the installation and debugging efficiency of the grab bucket and ensure the horizontal state of the grab bucket.

[0009] Furthermore, it also includes: a first mounting hole, which is formed on the lifting lug body, and the adjusting component is installed in the first mounting hole by a threaded connection.

[0010] Furthermore, it also includes: a mounting groove, formed on the lifting lug body, located on the plane where the central axis of the first mounting hole is located, through which the first mounting hole passes; a second mounting hole, formed on the lifting lug body, the central axis of the second mounting hole being perpendicular to the central axis of the first mounting hole; and a clamping component, installed in the second mounting hole, used to compress the mounting groove, thereby clamping the adjusting component into the first mounting hole.

[0011] Furthermore, two second mounting holes are symmetrically provided on both sides of the first mounting hole.

[0012] Furthermore, it also includes: a gasket, disposed at one end of the adjusting component; a cone-shaped pressure head, disposed at the other end of the adjusting component; and a tapered hole, formed on the mounting block, with the pressure head embedded in the tapered hole.

[0013] Furthermore, it also includes a third mounting hole, which is provided on the mounting block.

[0014] Furthermore, it also includes: an installation groove, formed along the outer contour of the wedge-shaped block, for embedding and installing the wire rope.

[0019] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0020] Reference Figure 1 and Figure 2 As shown, this utility model provides an adjustable lifting lug for a grab bucket type automatic bar screen cleaning machine, including: a lifting lug body 1; a wedge block 2 for fastening a steel wire rope; a wedge groove 11, which is smaller at the bottom and larger at the top along the direction of gravity, and is opened in the lifting lug body 1, and the wedge block 2 can be embedded in the wedge groove 11; wherein, the steel wire rope 5 passes between the wedge block 2 and the wedge groove 11; an adjusting component 3, which is located on the lower side of the wedge block 2 along the direction of gravity and is telescopically installed on the lifting lug body 1; and a mounting block 4, which is rotatably sleeved on the end of the adjusting component 3 away from the wedge block 2 and is detachably installed on the grab bucket.

[0021] In practical use, the mounting block 41 is installed on the grab bucket, and the wire rope 5 is wound around the wedge block 2 along the outer contour of the wedge block 2, so that the wedge block 2 can hold the wire rope tightly in the wedge groove.

[0022] When adjusting the installation status of the grab bucket, the distance between the wedge block 2 and the mounting block 4 on the lifting lug body 1 can be changed by adjusting the extension and retraction of the adjusting component 3 on the lifting lug body 1, thereby adjusting the installation status of the grab bucket until the grab bucket is placed in a horizontal installation state.

[0023] It is worth mentioning that two or more lifting lug bodies 1 can be installed on a grab bucket, and each lifting lug body 1 is connected to the winch by a steel wire rope 5. By using this utility model, the distance between the wedge block 2 and the mounting block 4 on each corresponding lifting lug body 1 can be finely adjusted until the grab bucket is in a horizontal installation state, preventing the grab bucket from tipping over.

[0024] In this utility model, an adjustment component 3 is provided, which can avoid frequent disassembly and assembly of the wire rope, facilitate the adjustment of the installation status of the grab bucket by the staff, improve the installation and debugging efficiency of the grab bucket, ensure that the grab bucket is in a horizontal state, and prevent the grab bucket from tipping over.

[0025] Specifically, it also includes: a first mounting hole, which is opened on the lug body 1, and an adjusting component 3 is installed in the first mounting hole by a threaded connection.

[0026] In this embodiment, the adjusting component 3 is threadedly connected to the first mounting hole. When the operator rotates the adjusting component 3, it can extend or retract along the axial direction of the first mounting hole, thereby moving closer to or further away from the wedge block 2, and thus adjusting the distance between the mounting block 4 and the wedge block 2.

[0027] It is worth mentioning that the adjusting component 3 can be a screw that is already available on the market. The screw has an internal hexagon countersunk hole on the nut, and the operator can rotate the adjusting component 3 by moving it with a wrench.

[0028] In some embodiments, a telescopic component can be used instead of a screw. The main body of the telescopic component is fixedly installed on the lifting lug body 1 by bolts, and the mounting block 4 is installed on the piston rod of the telescopic component. By driving the piston rod of the telescopic component to perform telescopic movement, the distance between the mounting block 4 and the wedge block 2 can also be adjusted. The telescopic component can be a cylinder or a hydraulic cylinder.

[0029] Specifically, it also includes: a mounting groove 13, which is formed on the lug body 1 and is located on the plane where the central axis of the first mounting hole is located, and passes through the first mounting hole; a second mounting hole 12, which is formed on the lug body 1, and the central axis of the second mounting hole 12 is perpendicular to the central axis of the first mounting hole; and a clamping component, which is installed in the second mounting hole 12 and is used to compress the mounting groove 13, thereby clamping the adjusting component 3 into the first mounting hole.

[0030] It is worth mentioning that, along the axial direction of the first mounting hole, the length of the first mounting hole is greater than the length of the mounting groove 13.

[0031] In this embodiment, the clamping component is a screw, and the inner wall of the second mounting hole 12 on one side of the mounting groove 13 is tapped. After the spacing between the wedge block 2 and the mounting block 4 is adjusted, the operator screws the clamping component and installs it in the second mounting hole 12. This causes the screw nut to squeeze the lifting lug body 1 on both sides of the mounting groove 13, thereby compressing the mounting groove 13 and clamping the adjusting component 3 in the first mounting hole to prevent the adjusting component 3 from loosening and to ensure the overall stability and reliability of the installation of the lifting lug body 1.

[0032] It is understandable that the clamping component can also be made of bolts and nuts, with the bolts passing through the second mounting hole 12, one side of the lifting lug body 1 being pressed by the bolt nut, and the other side of the lifting lug body 1 being pressed by the nut.

[0033] Specifically, two second mounting holes 12 are symmetrically opened on both sides of the first mounting hole, and two clamping components are provided accordingly to further prevent the adjusting component 3 from loosening and ensure the overall stability and reliability of the installation of the lifting lug body 1.

[0034] Specifically, this utility model also includes: a gasket 31, which is disposed at one end of the adjusting component 3 and can be used to press the wedge block 2; a pressure head 32, which is conical and disposed at the other end of the adjusting component 3; and a conical hole 41, which is opened on the mounting block 4 and the pressure head 32 is embedded in the conical hole 41.

[0035] Specifically, when the wire rope 5 is in the tightened state, the mounting block 4 does not move, and when the wire rope 5 is in the slack state, the tension of the wire rope 5 is released.

[0036] Inevitably, in actual operation, the wire rope 5 may become tangled. Due to the force below the wire rope 5, the tangled wire rope 5 is in a taut state during hoisting, and the lifting lug body 1 and the mounting block 4 are in a relatively stationary state, with the mounting block 4 not moving. When the grab bucket lands, the tangled wire rope 5 releases tension from the taut state to the slack state. During the tension release process, the wire rope 5 can drive the lifting lug body 1 and the mounting block 4 to generate relative rotational motion, thus completing the tension release of the wire rope 5.

[0037] This utility model also includes: a third mounting hole 42, which is provided on the mounting block 4; specifically, the lifting lug body 1 is installed on the grab bucket by means of bolts passing through the third mounting hole 42 and the grab bucket, and by means of nuts.

[0038] Preferably, the present invention further includes: an installation groove 13, which is formed along the outer contour on the wedge block 2 for embedding and installing the wire rope 5 and guiding the wire rope 5 to wind around the wedge block 2.

[0039] Those skilled in the art will understand that although preferred embodiments of the present invention have been described, those skilled in the art, once they learn the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention. Clearly, those skilled in the art can make various alterations and modifications to the present invention without departing from its spirit and scope. Thus, if these modifications and modifications of the present invention fall within the scope of the machine equivalents of the claims of the present invention, the present invention also intends to include these modifications and modifications.
