[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] The following is combined Figures 1 to 6 The following describes embodiments of the present invention.

[0037] According to an embodiment of the present invention, a locking device is provided for fixing the wire rope head 3. The locking device includes: a limiting seat 1 and a mating seat 2.

[0038] The limiting seat 1 has a placement position and an opening 1012 communicating with the placement position. The placement position has a limiting surface for abutting and cooperating with the wire rope head 3. The wire rope 4 is suitable to enter the placement position through the opening 1012.

[0039] The mating seat 2 is detachably mounted on the limiting seat 1. The mating seat 2 has a locked state that blocks the opening 1012 and an unlocked state that opens the opening 1012.

[0040] The locking device of this embodiment has a placement position on the limiting seat 1, and the mating seat 2 is detachably set on the limiting seat 1. When the wire rope head 3 needs to be fixed, the mating seat 2 is set to the unlocked state. At this time, the wire rope 4 connected to the wire rope head 3 can enter the placement position through the opening 1012. The limiting surface of the placement position can play a limiting role, thereby restricting the position of the wire rope head 3. At this time, the mating seat 2 is set to the locked state, and the fixing step of the wire rope head 3 can be completed. The overall structure of the device is simple and reliable, easy to use and has a long service life. During long-term use, there is no need to frequently replace parts, which effectively solves the problem of poor convenience of use of the existing wire rope fixing method on cranes.

[0041] The specific form of the mating seat 2 is not limited; it can be a sheet structure or a block structure, as long as it can block the opening 1012.

[0042] Additionally, it should be noted that there is no limitation on the specific form of the sealing of the opening 1012 by the mating seat 2. It can completely block the opening 1012 or block part of the opening 1012, as long as it can prevent the wire rope 4 and the wire rope head 3 from coming out of the opening 1012.

[0043] In one possible implementation, such as Figure 1 and Figure 2 As shown, the limiting seat 1 is provided with a limiting groove 1011 for the steel wire rope 4 to pass through. The limiting groove 1011 forms a placement position. The placement position in the form of the limiting groove 1011 has a simple and reliable structure and is easy to process and manufacture.

[0044] It is understood that, as an alternative implementation method, a limiting cavity can also be provided on the limiting seat 1. The limiting cavity is connected to the outside through the opening 1012. After the wire rope head 3 enters the limiting cavity through the opening 1012, the mating seat 2 is set at the opening 1012 so that the through area of ​​the opening 1012 is smaller than the cross-sectional area of ​​the wire rope head 3, thereby restricting the wire rope head 3 in the limiting cavity.

[0045] In one possible implementation, such as Figure 1 and Figure 2 As shown, the limiting seat 1 includes a limiting plate 101 and a connecting plate 102 that is bent and connected to the limiting plate 101. The connecting plate 102 is used for connecting to the machine body. The limiting groove 1011 and the opening 1012 are both located on the limiting plate 101. The limiting seat 1 is simple and reliable in form and occupies little space. The fixing method of connecting to the machine body through the connecting plate 102 is stable and reliable. The limiting groove 1011 is opened on the limiting plate 101 to facilitate processing and manufacturing.

[0046] Specifically, such as Figure 2 As shown, there is no limitation on the forming method of the limiting plate 101 and the connecting plate 102. They can be formed by bending an integral plate, by welding separate plates, or by machining. The specific forming method can be flexibly selected.

[0047] In addition, the connection position of the connecting plate 102 and the limiting plate 101 is not limited. The ends of the connecting plate 102 and the limiting plate 101 can be connected, or the end faces of the limiting plate 101 and the connecting plate 102 can be connected to form a T-shaped structure.

[0048] In one possible implementation, such as Figure 1 and Figure 2As shown, the connecting plate 102 is detachably connected to the machine body via the connector 103. The connecting plate 102 is provided with a strip hole 1021 for the connector 103 to pass through. The connection between the connecting plate 102 and the machine body is simple and reliable. The strip hole 1021 can also flexibly adjust its own fixed position according to the needs, which can improve the flexibility of the locking device.

[0049] Specifically, there is no limit to the number of strip holes 1021 on the connecting plate 102; there can be one or more, and the number can be flexibly selected according to the needs.

[0050] Preferably, such as Figure 2 As shown, the connector 103 is a bolt, and the strip hole 1021 is arranged in two spaced-apart arrangements, which can effectively avoid the risk of the limit seat 1 rotating when there is only one strip hole 1021.

[0051] In one possible implementation, such as Figure 1 and Figure 5 As shown, one end of the mating seat 2 is hinged to the limiting seat 1, and the other end is detachably connected to the mating seat 2. With this type of mating seat 2, it is not necessary to completely remove the mating seat 2 during use. You only need to remove one end of the mating seat 2 and rotate it along the other end to switch its own locking state. The method of use is simple and efficient.

[0052] Specifically, since mating seat 2 does not need to be completely removed, the risk of mating seat 2 falling and being lost can be effectively reduced.

[0053] It is understandable that, as an alternative implementation, the mating seat 2 can also be connected to the mating seat 2 with both ends being detachable.

[0054] Additionally, it should be noted that the mating seat 2 can also be detachably connected to the mating seat 2 via its own snap-fit ​​structure, etc.

[0055] In one possible implementation, such as Figure 1 and Figure 3 As shown, the mating seat 2 includes a mating plate 201, a hinge 202, and a locking member 203;

[0056] The mating plate 201 is provided with a first hinge hole 2011, and the limiting plate 101 is provided with a second hinge hole 1013. The hinge member 202 passes through the first hinge hole 2011 and the second hinge hole 1013 in sequence, and hinges the mating seat 2 and the limiting plate 101.

[0057] The mating plate 201 is provided with a first locking hole 2012, and the limiting plate 101 is provided with a second locking hole 1014. The first locking hole 2012 and the second locking hole 1014 are detachably connected by a locking member 203. The mating seat 2 is simple and reliable and easy to process and manufacture.

[0058] Specifically, such as Figure 1 As shown, the mating plate 201 mates with the side wall of the limiting plate 101, and the mating plate 201 can swing along the plane where the side wall of the limiting plate 101 is located.

[0059] In one possible implementation, such as Figure 4 As shown, the hinge 202 is a D-type pin. The hinge 202 is simple and reliable. The D-type pin is easy to use and can also prevent itself from falling off during operation.

[0060] It is understood that, as an alternative implementation, the hinge 202 can also be other pins such as elastic pins or cotter pins, as long as it can achieve hinge connection.

[0061] In one possible implementation, such as Figure 1 and Figure 5 As shown, the locking component 203 is a D-shaped pin that passes through the first locking hole 2012 and the second locking hole 1014 in sequence. The locking component 203 has a simple and reliable structure, is easy to use, and can also prevent itself from falling off during operation.

[0062] It is understandable that, as an alternative implementation, the locking element 203 can also be a flexible pin, bolt, nut, or other connecting element, as long as it can achieve a detachable connection.

[0063] In one possible implementation, such as Figure 6 As shown, the locking member 203 is an elastic member. The first locking hole 2012 and the second locking hole 1014 are spaced apart along the inlet and outlet direction of the limiting groove 1011. One end of the elastic member is detachably connected to the first locking hole 2012, and the other end is detachably connected to the second locking hole 1014. This type of locking member 203 is easier to disassemble and can effectively improve the unlocking speed of the mating plate 201.

[0064] Specifically, such as Figure 6 As shown, the mating plate 201 is provided with a guide groove 2014, and the limiting plate 101 is provided with a detachable support member 204. The support member 204 can cooperate with the guide groove 2014, which can guide the swing process of the mating plate 201 and also position the locking position of the mating plate 201 to prevent the mating plate 201 from swinging too much.

[0065] Furthermore, such as Figure 6As shown, the locking element 203 is a spring, and hooks are provided on both sides of the spring. The spring is connected to the first locking hole 2012 and the second locking hole 1014 through the hooks. When in use, the operator can simply lift the end of the mating plate 201 where the first locking hole 2012 is located manually. When the operator releases the hand, the mating plate 201 will automatically reset under the action of the spring, which can improve the ease of use of the mating plate 201.

[0066] In one possible implementation, such as Figure 1 and Figure 3 As shown, a mating groove 2013 is formed on the mating plate 201 facing the limiting groove 1011. The mating groove 2013 and the limiting groove 1011 together form a placement space. The mating groove 2013 not only avoids the through-hole position of the limiting groove 1011, but also has higher structural strength in the overlapping part of the mating groove 2013 and the limiting groove 1011. This can effectively improve the limiting reliability of the placement space.

[0067] Specifically, such as Figure 6 As shown, the bottom surface of the mating groove 2013 is an arc-shaped surface, which can effectively match the outer wall of the wire rope 4.

[0068] According to an embodiment of the present invention, another aspect provides a crane, which includes: a body, a turntable base, and the aforementioned locking device; the turntable base is disposed on the body; and the locking device is disposed on the turntable base.

[0069] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
