Description

Technical Field

[0001] This utility model relates to the field of crushing devices, and in particular to a hanger bolt assembly for an impact crusher. Background Technology

[0002] An impact crusher is a device that crushes materials by applying impact force to them using high-speed rotating hammers. It features a large crushing ratio and high production efficiency, and is widely used in industries such as mining, construction, chemical, and metallurgy. The hanger bolt is a crucial component of the impact crusher's impact frame adjustment device. Most existing hanger bolts have one end hinged to the impact frame via a pin, while the other end is fixed to the outside of the frame by an adjusting nut. Rotating the adjusting nut adjusts the length of the hanger bolt inside the frame, thereby causing the impact frame to rotate around the suspension shaft.

[0003] However, traditional hanger bolts consist of two parts: a U-shaped connecting fork and a tie rod. The U-shaped connecting fork is made of thick steel plate through blanking or casting, which results in a high manufacturing cost for hanger bolts. Utility Model Content

[0004] In view of the above problems, this utility model is proposed to provide a hanger bolt assembly for an impact crusher that overcomes or at least partially solves the above problems. It can solve the problem that the U-shaped connecting fork is usually made of thick steel plate through blanking or casting, which leads to high manufacturing cost of hanger bolts, thereby achieving the purpose of reducing the manufacturing cost of hanger bolts.

[0005] Specifically, this utility model provides a hanger bolt assembly for an impact crusher, comprising: A pull rod, comprising a fixing part and a connecting part. The fixing part is provided with a threaded structure, and a connecting plate disposed perpendicular to the extending direction of the pull rod is fixedly connected to the connecting part.

[0006] Two ear plates are symmetrically connected to both sides of the connecting plate. One of the ear plates and the connecting plate is provided with a plug-in interface, and the other is provided with a plug-in post, which is plugged into the plug-in interface one by one.

[0007] The ear plate and the connecting plate are welded together.

[0008] Optionally, a positioning block is formed at the end of the connecting portion away from the fixing portion. The positioning block includes two symmetrically arranged planar structures, and the planes containing the two planar structures are tangent to the pull rod. The ear plate is in contact with the planar structures.

[0009] Optionally, the positioning block and the pull rod are stepped, the positioning block and the pull rod are coaxially arranged, and the radius of the positioning block is larger than that of the pull rod.

[0010] The connecting plate is positioned in contact with the positioning block.

[0011] Optionally, a circular hole is formed on the connecting plate, and the connecting plate is sleeved on the pull rod through the circular hole and welded to the pull rod.

[0012] Optionally, the insertion interface is formed on the ear plate, and the insertion post is formed on the connecting plate. The ear plate also has a hinge hole spaced apart from the insertion interface, located at the end of the ear plate away from the pull rod.

[0013] The connector is a square opening, and the plug post is a square post that matches the shape of the square opening.

[0014] The connecting plate also includes a stop plate that extends along a direction perpendicular to the extension of the plug post, so that the connecting plate is a cross-shaped plate.

[0015] Optionally, the end of the plug-in post away from the pull rod protrudes from the side of the ear plate away from the pull rod.

[0016] In the hanger bolt assembly of this utility model, the ear plate and the connecting plate are separate structures, both of which can be processed from relatively thin steel plates. Compared with the integrally formed hanger bolt assembly, the forming of the ear plate and the connecting plate in the hanger bolt assembly of this utility model is simpler, thus simplifying the forming of the hanger bolt assembly formed by inserting the ear plate and the connecting plate and then welding them, thereby reducing the manufacturing cost of the hanger bolt assembly. Moreover, inserting the ear plate and the connecting plate before welding not only restricts the relative position of the ear plate and the connecting plate before welding to simplify the welding difficulty, but also reduces stress concentration compared with integrally formed or directly welded hanger bolt assemblies, improving the connection strength between the ear plate and the connecting plate in the hanger bolt assembly of this utility model and ensuring the working stability of the hanger bolt assembly.

[0024] Figure 1 This is a schematic structural diagram of a hanger bolt assembly according to an embodiment of the present invention, as shown below. Figure 1 As shown, and refer to Figures 2 to 3 This utility model provides a hanger bolt assembly for an impact crusher. The hanger bolt assembly includes a tie rod 100 and two lug plates 200. A connecting plate, perpendicular to the extending direction of the tie rod, is fixedly connected to the connecting portion. The pull rod 100 includes a fixing part 110 and a connecting part 120. The fixing part 110 is provided with a threaded structure 111, and the connecting part 120 is fixedly connected with a connecting plate 121 that is arranged perpendicular to the extension direction of the pull rod 100.

[0025] Two ear plates 200 are spaced apart and symmetrically connected to both sides of the connecting plate 121. One of the ear plates 200 and the connecting plate 121 is provided with a plug interface 210, and the other is provided with a plug post 1211. The plug posts 1211 are plugged into the plug interface 210 one by one, and the ear plates 200 and the connecting plate 121 are welded together.

[0026] A hinge hole 400 is formed on one side of the ear plate 200, through which the hanger bolt assembly is hinged to the counter-attack frame. The other side of the ear plate 200 has a plug-in interface 210 or a plug-in post 1211 for connection to the connecting plate 121. The hanger bolt assembly needs to withstand vibration and impact from the counter-attack frame during operation, requiring high structural strength. To ensure structural strength, traditional hanger bolt assemblies consist of a U-shaped connecting fork and a tie rod 100. However, the U-shaped connecting fork is mostly made from thick steel plates through blanking or casting, resulting in high manufacturing costs for the hanger bolt assembly.

[0027] In this embodiment, the ear plate 200 and the connecting plate 121 are separate structures, both of which can be processed from relatively thin steel plates. Compared with the integrally formed hanger bolt assembly, the forming of the ear plate 200 and the connecting plate 121 in the hanger bolt assembly of this utility model is simpler. This makes the forming of the hanger bolt assembly formed by inserting the ear plate 200 and the connecting plate 121 and then welding them simpler, reducing the manufacturing cost of the hanger bolt assembly. Moreover, the insertion and welding of the ear plate 200 and the connecting plate 121 not only restricts the relative position of the ear plate 200 and the connecting plate 121 before welding to simplify the welding difficulty, but also reduces stress concentration compared with integrally formed or directly welded hanger bolt assemblies, as the separate and inserted structure of the ear plate 200 and the connecting plate 121 reduces stress concentration and improves the connection strength of the ear plate 200 and the connecting plate 121 in the hanger bolt assembly of this utility model, ensuring the working stability of the hanger bolt assembly.

[0028] In some embodiments of this utility model, such as Figure 2 As shown, a positioning block 300 is formed at the end of the connecting part 120 away from the fixing part 110. The positioning block 300 includes two symmetrically arranged planar structures 310, and the planes on which the two planar structures 310 are located are tangent to the pull rod 100. The side of each ear plate 200 near the pull rod 100 is in contact with one planar structure 310.

[0029] In this embodiment, the opposite sides of the two ear plates 200 are respectively in contact with a planar structure 310, so that the positioning block 300 and the ear plate 200 are in surface contact. This allows the planar structure 310 to not only limit the ear plate 200, facilitating its installation when it is inserted into the connecting plate 121, thus preventing the ear plate 200 from shifting around the axis of the tie rod 100 and causing it to be improperly installed, but also to increase the contact area between the ear plate 200 and the tie rod 100, thereby improving the connection strength between them. Furthermore, the ear plate 200 is welded to the positioning block 300, and the increased contact area between the ear plate 200 and the positioning block 300 further increases the welding area between the ear plate 200 and the tie rod 100, further improving the connection strength between them.

[0030] In some embodiments of this utility model, such as Figure 2 As shown, the positioning block 300 and the pull rod 100 are stepped, coaxially arranged, and the radius of the positioning block 300 is larger than that of the pull rod 100. The connecting plate 121 is in contact with the positioning block 300.

[0031] In this embodiment, a step is formed on the tie rod 100, and the step formed by the connecting plate 121 and the positioning block 300 is in contact, which improves the connection strength between the connecting plate 121 and the tie rod 100, thereby improving the reliability of the hanger bolt assembly.

[0032] In some embodiments of this utility model, a circular hole is formed on the connecting plate 121, and a threaded structure 111 is provided in the circular hole. The connecting plate 121 is threadedly connected to the pull rod 100 through the threaded structure 111.

[0033] In this embodiment, the step formed by the positioning block 300 also serves to limit the connection plate 121, eliminating the need to observe whether the installation position of the connection plate 121 is in the designated installation position, thus facilitating the installation of the connection plate 121 into place when it is threadedly connected to the tie rod 100.

[0034] In some embodiments of this utility model, a circular hole is formed on the connecting plate 121, and the connecting plate 121 is sleeved on the pull rod 100 through the circular hole and welded to the pull rod 100.

[0035] In this embodiment, the pull rod 100 passes through the circular hole of the connecting plate 121, and the connecting plate 121 is welded to the pull rod 100 when the connecting plate 121 is in the designated installation position. This welding connection eliminates the need for a threaded structure 111 at the connection between the connecting plate 121 and the pull rod 100, reducing the machining of the threaded structure 111 and thus lowering processing costs. Furthermore, the contact between the connecting plate 121 and the positioning block 300 limits the position of the connecting plate 121, eliminating the need to observe whether the connecting plate 121 is properly installed during installation. This simplifies the installation method and increases the installation accuracy of the connecting plate 121. The limited-position connecting plate 121 can also be welded to the pull rod 100 without the need for hand or other tool support, further reducing the difficulty of the welding operation.

[0036] In some embodiments of this utility model, a circular hole is formed on the connecting plate 121, and a threaded structure 111 is provided in the circular hole. The connecting plate 121 is threadedly connected to the pull rod 100 through the threaded structure 111, and the pull rod 100 and the connecting plate 121 are welded together.

[0037] In this embodiment, the connecting plate 121 is first connected to the pull rod 100 through the threaded structure 111. After the connecting plate 121 is installed in place, the connecting plate 121 is welded to the pull rod 100, so that the fixed connection between the connecting plate 121 and the pull rod 100 is more secure.

[0038] Furthermore, when the connecting plate 121 is threadedly connected to the tie rod 100, the contact between the connecting plate 121 and the positioning block 300 limits the position of the connecting plate 121. This eliminates the need to observe whether the connecting plate 121 is properly installed during installation, simplifying the installation process and increasing the installation accuracy of the connecting plate 121. The limited-position connecting plate 121 also eliminates the need for hand or other tools to support it during welding to the tie rod 100, further reducing the difficulty of the welding operation.

[0039] In some embodiments of this utility model, such as Figure 2 As shown, the insertion interface 210 is formed on the ear plate 200, and the insertion post 1211 is formed on the connecting plate 121. The ear plate 200 also has a hinge hole 400 spaced apart from the insertion interface 210, and the hinge hole 400 is located at the end of the ear plate 200 away from the pull rod 100.

[0040] The connector 210 is a square opening, and the plug post 1211 is a square post that matches the square opening surface.

[0041] In this embodiment, symmetrical insertion posts 1211 are provided on opposite sides of the connecting plate 121. The square posts are inserted into the square holes formed on the ear plate 200. The square structure can not only prevent the ear plate 200 from moving vertically or horizontally relative to the connecting plate 121, but also prevent the ear plate 200 from rotating around the insertion posts 1211.

[0042] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the connecting plate 121 also includes a stop plate 1212, which extends along a direction perpendicular to the extension of the plug post 1211, so that the connecting plate 121 is a cross-shaped plate.

[0043] In this embodiment, the stop plate 1212 serves to limit and stop the ear plate 200, which not only facilitates the installation of the ear plate 200 in place, but also prevents the ear plate 200 from deviating around the axis of the pull rod 100.

[0044] Furthermore, in some embodiments of this utility model, the end of the stop plate 1212 away from the pull rod 100 is flush with the surface of the ear plate 200, which increases the contact area between the ear plate 200 and the connecting plate 121, and improves the connection strength between the ear plate 200 and the connecting plate 121 after welding.

[0045] In some embodiments of this utility model, the stopping surface of the stop plate 1212 is flush with the planar structure 310 of the positioning block 300. That is, after the ear plate 200 is connected to the connecting plate 121, it simultaneously contacts the stop plate 1212 and the positioning block 300.

[0046] In some embodiments of this utility model, such as Figure 1 As shown, the end of the plug post 1211 away from the pull rod 100 protrudes from the side of the ear plate 200 away from the pull rod 100.

[0047] In this embodiment, when the plug-in post 1211 formed on the connecting plate 121 is inserted into the plug-in interface 210, and after the connecting plate 121 and the ear plate 200 are installed in place, the plug-in post 1211 extends out from the plug-in interface 210, so that a protruding welding part is formed between the connecting plate 121 and the ear plate 200 to facilitate welding. At the same time, it also maximizes the contact area between the connecting post and the plug-in interface 210, further improving the connection strength between the connecting plate 121 and the ear plate 200.

[0048] In some embodiments of this utility model, the ratio of the width to the length of the insertion interface 210 and the ear plate 200 is between 0.5 and 0.8.

[0049] The ratio of the width of the connector 210 to the length of the ear plate 200 is between 0.05 and 0.15.

[0050] In this embodiment, when the insertion interface 210 occupies too much of the total area of ​​the ear plate 200, the structural strength of the ear plate 200 is poor. When the insertion interface 210 occupies too little of the total area of ​​the ear plate 200, the contact area between the insertion interface 210 and the insertion post 1211 is small after the connecting plate 121 and the ear plate 200 are connected, which is not conducive to improving the connection strength between the connecting plate 121 and the ear plate 200.

[0051] In some embodiments of this utility model, such as Figure 3 As shown, the hanger bolt assembly also includes a jacking device. The jacking device is threaded to the fixing part 110 to control the movement of the tie rod 100, and in turn, controls the movement of the counter-attack frame of the hinge and ear plate 200 by controlling the movement of the tie rod 100.

[0052] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
