Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] The following is for reference. Figures 1-6 Description of a pin disassembly and assembly device 100 for a metallurgical crane plate hook according to an embodiment of the present invention.

[0031] like Figures 1-6 As shown, according to an embodiment of the present invention, a pin disassembly and assembly device 100 for a metallurgical crane plate hook can be installed on a base body via a pin 200. The pin disassembly and assembly device 100 may include a support member 10, a clamping assembly, and an impact rod 40. The clamping assembly can be disposed on the support member 10 and can move relative to the support member 10 to clamp the base body, thereby fixing the entire pin disassembly and assembly device 100 on the base body and the pin 200. This prevents the pin disassembly and assembly device 100 from moving relative to the base body and the pin 200 during operation, which is beneficial for disassembling and assembling the pin 200 and can improve the stability of disassembling and assembling the pin 200.

[0032] The impact rod 40 can be mounted on the support member 10, and the impact rod 40 can move relative to the support member 10. Since the clamping assembly can clamp the seat to fix the entire pin disassembly and assembly device 100 to the seat, the impact rod 40 can move relative to the pin 200 and the seat. The impact rod 40 can be arranged opposite to the end face of the pin 200 when the clamping assembly clamps the seat, and the impact rod 40 can move along the extension direction of the pin 200 (e.g., ...). Figure 2 (Extends in the forward and backward directions as shown).

[0033] This allows the impact rod 40 to move along its extension direction to impact the end face of the pin 200, so that the pin 200 can move relative to the hook to insert into or detach from the hook. This ensures that the direction of the impact force applied by the impact rod 40 to the end face of the pin 200 coincides with the extension direction of the pin 200 when the impact rod 40 impacts the pin 200. This ensures that the pin 200 is subjected to uniform force during disassembly and assembly, and eliminates the risk of uneven load on the pin 200 due to uneven force.

[0034] This prevents the pin 200 and the hook from interfering with each other during assembly and disassembly, allowing the pin 200 to move more smoothly relative to the hook when impacted by the impact rod 40. This improves the smoothness and stability of the pin 200 assembly and disassembly, increases the speed of assembly and disassembly, enables rapid assembly and disassembly of the pin 200, reduces the difficulty of assembly and disassembly of the pin 200, and improves the efficiency of assembly and disassembly of the pin 200. For example, the efficiency of assembly and disassembly of the pin 200 can be increased to more than 300%.

[0035] It can also prevent the impact rod 40 from deviating from the specified direction due to the impact force direction (such as... Figure 1 (As shown in the front and back directions) to bend and damage the pin 200, and to prevent the impact rod 40 from impacting the plate hook due to the impact position deviating from the designated position (such as the end face of the pin 200) and causing damage to the plate hook. This can improve the accuracy and reliability of the pin 200 disassembly and assembly, and prevent the pin 200 and plate hook from being damaged by repeated disassembly and assembly. It can reduce the cost of spare parts wear, for example, the cost of spare parts wear can be reduced to 40%, and the safety hazards of the pin 200 disassembly and assembly can be reduced.

[0036] Understandably, in combination Figure 2 and Figure 4 The clamping assembly can clamp the seat multiple times to adjust the position of the pin mounting / dismounting device 100, for example, in the extending direction of the pin 200 (e.g., Figure 4 In the forward / backward direction shown, the impact rod 40 can be located on one side of the pivot pin 200 (e.g., in the forward / backward direction). Figure 4 (as shown on the front side), the impact rod 40 can move towards the direction of the pivot pin 200 (e.g. Figure 2 The movement (as shown in the front-to-back direction) impacts the pin 200 to insert it into the plate hook, thus enabling the installation of the pin 200. The impact rod 40 can be located on the other side of the pin 200 (e.g., ...). Figure 4 (as shown on the rear side), the impact rod 40 can move towards the direction of the pivot pin 200 (e.g. Figure 2 The movement (shown from back to front) impacts the pin 200 to dislodge it from the plate hook, thus enabling the pin 200 to be disassembled.

[0037] The axle pin 200 can be disassembled or assembled manually by striking one end of the impact rod 40 with an impact hammer (e.g., Figure 2 (as shown at the rear end), so that the other end of the impact rod 40 (as shown) Figure 2 The impact rod 40 is used to indirectly strike the end face of the axle pin 200. Compared with the method of directly striking the axle pin 200 with an impact hammer, the impact rod 40 can ensure that the direction of the impact force coincides with the extension direction of the axle pin 200. This ensures that the axle pin 200 is subjected to uniform force during disassembly and assembly, eliminates the risk of uneven load on the axle pin 200 due to uneven force, improves the smoothness and stability of the disassembly and assembly of the axle pin 200, improves the accuracy and reliability of the disassembly and assembly of the axle pin 200, and prevents the axle pin 200 and the plate hook from being damaged during disassembly and assembly.

[0038] Of course, one end of the impact rod 40 (such as...) Figure 2 A jack can be installed near the rear end (as shown), allowing the axle pin 200 to be disassembled or assembled by pressing the impact rod 40 with the jack. The impact rod 40 can then force the axle pin 200 into or off the plate hook. This ensures that the impact force applied by the impact rod 40 to the axle pin 200 is small and reduces the impact of the impact rod 40 on the axle pin 200. This ensures that the axle pin 200 is subjected to more even force during disassembly and assembly, further eliminating the risk of uneven load on the axle pin 200 due to uneven force. In other words, by slowing down the disassembly speed of the axle pin 200, the reliability and stability of the disassembly and assembly of the axle pin 200 are further improved.

[0039] According to the embodiment of the present invention, the axle pin disassembly and assembly device 100 for a metallurgical crane hook, by setting a clamping assembly to clamp the seat body and by setting an impact rod 40 to impact the end face of the axle pin 200 in the extension direction of the axle pin 200, can ensure that the axle pin 200 is subjected to uniform force during disassembly and assembly, and can eliminate the risk of off-center load caused by uneven force on the axle pin 200. This improves the smoothness and stability of the axle pin 200 disassembly and assembly, increases the speed of disassembly and assembly, and enables rapid disassembly and assembly of the axle pin 200. Furthermore, it can improve the accuracy and reliability of the disassembly and assembly of the shaft pin 200, prevent the shaft pin 200 and the plate hook from being damaged after repeated disassembly and assembly, thereby reducing the difficulty and safety hazards of disassembly and assembly of the shaft pin 200, and improving the efficiency of disassembly and assembly of the shaft pin 200. In addition, by setting clamping components and impact rods 40 on the support member 10 respectively, the shaft pin 200 can be disassembled and assembled stably, which can simplify the structure of the shaft pin disassembly and assembly device 100, facilitate disassembly and assembly, facilitate maintenance, and is also suitable for the harsh working conditions of the metallurgical industry, which helps to reduce costs.

[0040] like Figure 1 and Figure 3As shown, according to some embodiments of the present invention, the clamping assembly may include two clamping rods 20, and the support member 10 may be provided with a sliding groove 111. The clamping rods 20 can slide and cooperate with the sliding groove 111, which can realize the adjustment of the position of the clamping rods 20, so that the two clamping rods 20 can move closer to each other or further away from each other to clamp or release the seat. For example, the two clamping rods 20 can move closer to each other to clamp the seat, and the two clamping rods 20 can move further away from each other to release the seat, which is convenient for operation.

[0041] The clamping rod 20 can be fastened to the support member 10, which can fix the clamping rod 20 and prevent the two clamping rods 20 from automatically moving away from each other and releasing the seat when clamping the seat. This can improve the stability and reliability of the clamping assembly clamping the seat, thereby improving the reliability and stability of fixing the pin disassembly and assembly device 100. It can also prevent the pin disassembly and assembly device 100 from moving relative to the seat and pin 200 during operation, thus improving the stability and reliability of the pin 200 disassembly and assembly.

[0042] like Figure 1 and Figure 2 As shown, in some embodiments, the clamping rod 20 may include a clamping section 21 and a threaded section 22, one end of the threaded section 22 (e.g., Figure 2 The front end shown can be connected to the clamping section 21, and the other end of the threaded section 22 (as shown) can be connected to the clamping section 21. Figure 2 The rear end shown can pass through the support 10 via the groove 111, and the threaded section 22 can slide with the groove 111, so that the threaded section 22 can slide along the extension direction of the groove 111 (e.g., Figure 3 The two clamping rods 20 can move in the left and right directions as shown, so as to move the entire clamping rod 20 relative to the support member 10. This allows for adjustment of the position of the clamping rod 20, so that the two clamping rods 20 can move closer to each other to clamp the seat, and can also move further apart to release the seat, which is convenient for operation.

[0043] The clamping assembly may also include a fastener 30, which can be threadedly engaged with the threaded section 22, i.e., the fastener 30 can be inserted from the other end of the threaded section 22 (e.g., ...). Figure 2 The rear end shown is sleeved on the threaded section 22, and by rotating the fastener 30, the fastener 30 can be moved along the extension direction of the threaded section 22 (e.g., ...). Figure 2 (as shown in the left and right directions) movement, for example, the fastener 30 can move towards the clamping section 21 (as shown in the left and right directions). Figure 2 (As shown in the back-to-front direction) movement, until the fastener 30 and the support 10 are on one side (such as...) Figure 2 (The rear side shown) is in contact.

[0044] The radial dimension of the clamping section 21 can be larger than the radial dimension of the threaded section 22, and the clamping section 21 can be connected to the other side of the support member 10 (e.g., Figure 2 The front side shown) contacts, that is, the other end of the threaded section 22 (as shown) Figure 2 The rear end shown can pass through the slide groove 111 to drive the clamping section 21 to move until the clamping section 21 is close to the side of the threaded section 22 (e.g., Figure 2 The rear end face (as shown) contacts the support 10, thereby allowing the clamping rod 20 to be installed onto the support 10 so that a portion of the threaded section 22 passes through the support 10, and then the fastener 30 is installed and tightened onto the threaded section 22. This allows the clamping section 21 to engage with the fastener 30 to press against the opposite sides of the support 10 (e.g., the rear side). Figure 2 (The front and back sides are shown).

[0045] Therefore, the clamping rods 20 can be fixed, preventing the two clamping rods 20 from automatically moving away from each other and releasing the seat when clamping the seat. This improves the stability and reliability of the clamping assembly clamping the seat, thereby improving the reliability and stability of fixing the pin disassembly and assembly device 100. It also prevents the pin disassembly and assembly device 100 from moving relative to the seat and pin 200 during operation, thus improving the stability and reliability of disassembly and assembly of the pin 200.

[0046] like Figure 1 and Figure 2 As shown, in some embodiments, the end of the clamping rod 20 furthest from the support member 10 (e.g., Figure 1 The front end shown may have a clamping part 211, which may be located on one side of the two clamping rods 20 that are close to each other, i.e., located on the side of the front end that is close to each other. Figure 1 Taking the left-side clamping rod 20 as an example, a clamping part 211 can be located on the right side of the clamping rod 20, and is positioned as follows: Figure 1 Taking the right-side clamping rod 20 as an example, another clamping part 211 can be located on the left side of the clamping rod 20.

[0047] The two clamping rods 20 can move closer to each other so that the two clamping parts 211 move closer to each other to clamp the seat body, and the two clamping rods 20 can move further apart so that the two clamping parts 211 move further apart to release the seat body. This allows the clamping force applied by the clamping rods 20 to the seat body to be concentrated at a local position on the seat body through the clamping parts 211, thereby improving the clamping effect on the seat body, improving the fixing effect of the pin removal and installation device 100, preventing the pin removal and installation device 100 from moving relative to the seat body and the pin 200 during operation, and improving the stability and reliability of the pin 200 removal and installation.

[0048] like Figure 1 and Figure 2 As shown, in some embodiments, the support 10 and the clamping part 211 can be respectively attached to opposite sides of the base (e.g., Figure 1The front and rear sides of the wall are in contact with each other. That is, when the two clamping parts 211 clamp the seat body to fix the pin removal and installation device 100 to the seat body, the support member 10 and the clamping parts 211 can cooperate to jointly support the pin removal and installation device 100. This can improve the fixing effect of the pin removal and installation device 100, prevent the pin removal and installation device 100 from moving relative to the seat body and the pin 200 during operation, and improve the stability and reliability of the pin removal and installation.

[0049] like Figure 2 and Figure 3 As shown, in some embodiments, the extension direction of the groove 111 (e.g.) Figure 3 The left and right directions shown are perpendicular to the extension direction of the impact rod 40 (as shown). Figure 2 (as shown in the front-back direction), so that the two clamping rods 20 can be brought close to each other to the opposite sides of the seat (e.g., Figure 2 The two clamping rods 20 (shown on the left and right sides) contact each other to clamp the seat body. On the one hand, this increases the contact area between the clamping rods 20 and the seat body, making the seat body more evenly stressed and preventing damage to the seat body due to excessive concentration of clamping force. On the other hand, the two clamping rods 20 can cooperate to jointly support the pin disassembly and assembly device 100, which can improve the fixing effect of the pin disassembly and assembly device 100, prevent the pin disassembly and assembly device 100 from moving relative to the seat body and pin 200 during operation, and improve the stability and reliability of the pin 200 disassembly and assembly.

[0050] like Figure 3 As shown, in some embodiments, the number of slide grooves 111 can be one, and the two clamping rods 20 can be arranged on opposite sides of the slide groove 111 (e.g., Figure 3 (as shown on the left and right sides), and the two clamping rods 20 can slide and engage with the same slide groove 111 respectively, which facilitates processing. Alternatively, there can be two slide grooves 111, and the two slide grooves 111 are in their own extending direction (e.g. Figure 3 The two slides 111 are arranged opposite each other and spaced apart in the left-right direction (as shown), that is, the two slides 111 can be arranged in the same direction (e.g., ...). Figure 3 Extending on the left and right sides shown, and in the same direction as described above, the two grooves 111 can be arranged opposite to each other on opposite sides of the support member 10 (e.g., on the left and right sides). Figure 3 The left and right sides shown can prevent the clamping rod 20 from interfering with the base body before the shaft pin disassembly and assembly device 100 is fixed to the base body, making operation easier.

[0051] like Figure 2 As shown, in some embodiments, the fastener 30 can be a nut, which can be threaded into the threaded section 22, i.e., the nut can be inserted from the other end of the threaded section 22 (e.g., ...). Figure 2 The rear end shown is fitted onto the threaded section 22, and by rotating the nut, the nut can be positioned along the extension direction of the threaded section 22 (e.g., ...). Figure 2The nut can move in the left-right direction (as shown), for example, the nut can move towards the clamping section 21 (as shown). Figure 2 (As shown in the back-to-front direction) move until the nut and support 10 are on one side (e.g.) Figure 2 The contact shown on the rear side allows for tightening of the nut.

[0052] And the tightened nut and the clamping section 21 are close to the side of the support plate 11 (e.g. Figure 2 The rear end face shown can be matched with the support member 10 to fix the clamping rod 20, which can prevent the two clamping rods 20 from automatically moving away from each other and automatically releasing the seat when clamping the seat. This can improve the stability and reliability of the clamping assembly clamping the seat, thereby improving the reliability and stability of fixing the shaft pin disassembly and assembly device 100. It can also prevent the shaft pin disassembly and assembly device 100 from moving relative to the seat and shaft pin 200 during operation, thus improving the stability and reliability of disassembly and assembly of the shaft pin 200.

[0053] Understandably, there can be two nuts. The threaded section 22 can be machined with two sections of threads with opposite directions, so that the two nuts can be threaded into the threaded section 22 through different threads until one nut contacts the support 10 and the other nut contacts the first nut, so as to tighten the two nuts. This can achieve self-locking of the nuts and prevent the nuts from loosening or falling off when the pin disassembly and assembly device 100 is working.

[0054] Alternatively, the nut can be a wedge-shaped self-locking nut, i.e., one nut is a convex nut and the other is a concave nut. The conical grooves of the two nuts can interlock to generate radial compressive force, so that the contact surface between the nut and the threaded section 22 can undergo local plastic deformation, which can increase the friction of the threaded pair to achieve self-locking of the nut. This can improve the fixing effect of the clamping rod 20, improve the stability and reliability of the clamping assembly in clamping the seat, thereby improving the reliability and stability of fixing the pin removal and installation device 100, preventing the pin removal and installation device 100 from moving relative to the seat and pin 200 during operation, and improving the stability and reliability of the pin 200 removal and installation.

[0055] like Figure 1 , Figure 2 and Figure 3As shown, according to some embodiments of this utility model, the support member 10 may have a insertion hole, and the impact rod 40 can be inserted into the insertion hole. The impact rod 40 can move relative to the insertion hole, which can guide the movement of the impact rod 40, improve the stability of the movement of the impact rod 40, improve the stability of the impact rod 40 impacting the end face of the pin 200, ensure that the pin 200 is subjected to uniform force during disassembly and assembly, and eliminate the risk of uneven load on the pin 200 due to uneven force. This can improve the smoothness and stability of the disassembly and assembly of the pin 200, increase the speed of the disassembly and assembly of the pin 200, realize the rapid disassembly and assembly of the pin 200, improve the accuracy and reliability of the disassembly and assembly of the pin 200, and prevent the pin 200 and the plate hook from being damaged after repeated disassembly and assembly.

[0056] like Figure 1 and Figure 3 As shown, according to some embodiments of the present invention, the support member 10 may include a support plate 11 and a reinforcing rib 12. The clamping assembly and the impact rod 40 may be respectively disposed on the support plate 11. That is, the support plate 11 may be provided with a sliding groove 111 and a insertion hole, which is convenient for processing and facilitates the fit between the support plate 11 and the seat or plate hook when the clamping assembly clamps the seat, thereby increasing the contact area between the support plate 11 and the seat or plate hook.

[0057] Therefore, the support plate 11 and the clamping part 211 can cooperate to jointly support the pin disassembly and assembly device 100, which can improve the support effect of the pin disassembly and assembly device 100, improve the fixing effect of the pin disassembly and assembly device 100, prevent the pin disassembly and assembly device 100 from moving relative to the seat and the pin 200 during operation, and improve the stability and reliability of the pin 200 disassembly and assembly.

[0058] Among them, the reinforcing rib 12 can be set on one side of the support plate 11 (e.g., Figure 1 The rear side shown can improve the structural strength of the support plate 11, so that the impact rod 40 can apply a greater impact force to the shaft pin 200, which is beneficial for the shaft pin disassembly and assembly device 100 to disassemble and assemble the shaft pin 200. It is understood that the support plate 11 can be made of high-temperature resistant alloys such as nickel-based high-temperature alloys or iron-based high-temperature alloys, which can improve the structural strength and high-temperature resistance of the support member 10 and improve the service life of the support member 10.

[0059] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, according to some embodiments of the present invention, the clamping assembly can clamp the base body so that the pin disassembly and assembly device 100 can be fixed on the base body, and the support plate 11 can be attached to one side of the base body (e.g., Figure 4 (as shown on the rear side) fits together, and the impact rod 40 can move towards the direction of the shaft pin 200 (e.g. Figure 2 The movement (shown from back to front) impacts the pin 200 to dislodge it from the plate hook, thus enabling the pin 200 to be disassembled.

[0060] The clamping assembly can release and re-clamp the seat body, so that the pin removal and installation device 100 can be re-secured to the seat body, and the support plate 11 can be connected to the other side of the seat body (e.g., Figure 4 (as shown in the front side) fits together, and the impact rod 40 can move towards the direction of the shaft pin 200 (e.g. Figure 2 The movement (shown in the direction from front to back) impacts the pin 200 to insert the pin 200 into the plate hook, thus enabling the installation of the pin 200.

[0061] The side wall of the axle pin 200 may be provided with at least one set of grips 210. Each set of grips 210 may include two grips 210, which may be arranged opposite each other on opposite sides of the axle pin 200 to facilitate manual gripping to lift the entire axle pin 200, so that one end of the axle pin 200 (e.g., Figure 4 The rear end shown can be initially inserted into the plate hook, which can achieve the initial positioning of the shaft pin 200.

[0062] Each set of grip bars 210 can be fitted with an arc-shaped fixed clamp 220. The arc-shaped fixed clamp 220 can include two semi-arc semi-fixed clamps. In a set of grip bars 210, the two semi-fixed clamps can be fitted onto the two grip bars 210 respectively, and the two semi-fixed clamps can be fastened together by bolts to form a complete fixed clamp 220. This can improve the structural strength of the grip bars 210 and prevent the grip bars 210 from breaking when manually gripped.

[0063] It is understandable that the grip 210 can be welded to the pin 200, which ensures the structural strength of the connection between the grip 210 and the pin 200, prevents the grip 210 from breaking when manually gripped, and allows the grip 210 to be cut off manually after the pin 200 is installed, facilitating the installation of the pin 200. Alternatively, the other end of the pin 200 (such as...) Figure 4 The front end shown can be exposed on the outside of the plate hook, which can prevent the handle from interfering with the plate hook, facilitates the retention of the handle 210 after the shaft pin 200 is installed, facilitates the multiple disassembly and assembly of the shaft pin 200, and is easy to operate.
