Description

Technical Field

[0001] The present invention relates to the technical field of quay cranes, and particularly relates to a chassis of a quay crane machine room. Background Art

[0002] The connection between the chassis of a conventional quay crane machine room and the rear girder mainly adopts the form of high-strength bolt connection. Usually, there are many fixed supports between the chassis of the machine room and the rear girder, and the chassis support is a statically indeterminate structure. Moreover, due to manufacturing tolerances and deformations easily caused by external loads of the rear girder and the chassis, the contact surfaces of the flange of each support cannot be completely fitted, and there will be gaps. Furthermore, during the operation of the mechanism in the machine room, the chassis vibrates, and at the same time, the high-strength bolts are unevenly stressed and repeatedly stretched, resulting in fatigue fracture, which easily causes the chassis of the machine room to slide relative to the rear girder, seriously affecting the safety of the whole machine equipment.

[0051] First, the quayside container crane machine room chassis according to the embodiments of the present invention will be specifically described below with reference to the accompanying drawings.

[0052] The quayside container crane machine room chassis 100 according to the embodiments of the present invention, as shown in Figure 1 , 2As shown, it may include: a machine room chassis body 110 and a connection assembly 120.

[0053] Among them, the connection assembly 120 is arranged at the bottom of the machine room chassis body 110, and the connection assembly 120 is used to connect the machine room chassis body 110 to the rear girder 200 of the crane.

[0054] Among them, the connection assembly 120 includes a first connection assembly 121, a second connection assembly 122 and a third connection assembly 123. The first connection assembly 121, the second connection assembly 122 and the third connection assembly 123 are respectively used to restrict the machine room chassis body 110 from sliding in the vertical direction, the first direction and the second direction of the horizontal plane during the operation of the mechanism.

[0055] Specifically, for the quay crane machine room chassis 100 according to the embodiment of the present invention, by arranging the connection assembly 120 including the first connection assembly 121, the second connection assembly 122 and the third connection assembly 123 at the bottom of the machine room chassis body 110, the machine room chassis body 110 can be compactly and reliably installed in a predetermined area, and during the operation of the mechanism in the machine room, the machine room chassis body 110 will not slide relative to the rear girder 200, and the service durability is strong.

[0056] In some embodiments, as Figure 3 、 4 shown, the first connection assembly 121 may include: a plurality of first bolt assemblies 1211 and a first support 1212.

[0057] Among them, the top of the first support 1212 is connected to the machine room chassis body 110 in the vertical direction through a plurality of first bolt assemblies 1211, and the bottom of the first support 1212 is used to connect to the rear girder 200.

[0058] That is to say, by arranging the first connection assembly 121 at the bottom of the machine room chassis body 110 to connect the first support 1212, the machine room chassis body 110 and the first support 1212 are tightly connected and fixed up and down, and no loosening will occur.

[0059] In some embodiments, the first connection assembly 121 includes at least two pairs, and the two pairs of first connection assemblies 121 are respectively arranged at the four corners of the bottom of the machine room chassis body 110.

[0060] Specifically, for example, as Figure 2 shown, by respectively arranging the first connection assembly 121 at the four corners of the bottom of the machine room chassis body 110, the machine room chassis body 110 can be stably and effectively fixed on the rear girder 200, and it is not easy to shift and loosen.

[0061] In some embodiments, as Figure 5 、6 As shown, the second connection assembly 122 may include: a plurality of second bolt assemblies 1221, a second support 1222, and a pair of first shear plates 1223.

[0062] Among them, the top of the second support 1222 is connected to the machine room chassis body 110 in the vertical direction through a plurality of second bolt assemblies 1221, and the bottom of the second support 1222 is used to connect to the rear girder 200.

[0063] A pair of first shear plates 1223 are respectively connected to both sides of the second support 1222 in the first direction, and their tops are connected to the bottom of the machine room chassis body 110.

[0064] Among them, the first shear plate 1223 is used to restrain the machine room chassis body 110 from sliding in the horizontal first direction during the operation of the mechanism.

[0065] Specifically, the second connection assembly 122 is provided at the bottom of the machine room chassis body 110 to connect to the rear girder 200. Among them, by respectively connecting the first shear plates 1223 to both sides of the second support 1222 in the first direction of the second connection assembly 122, the machine room chassis body 110 is resisted from sliding in the first direction during the operation of the mechanism.

[0066] In some embodiments, the second connection assembly 122 includes at least a pair, and a pair of second connection assemblies 122 are respectively provided on both sides of the bottom of the machine room chassis body 110.

[0067] Specifically, for example, as Figure 2 shown, second connection assemblies 122 are respectively provided on both sides of the bottom of the machine room chassis body 110 to connect to the rear girder 200, so as to perform anti-slip fixation on both sides of the machine room chassis body 110 in the first direction, which is stable and reliable.

[0068] In some embodiments, as Figure 7 、 8 shown, the third connection assembly 123 may include: a plurality of third bolt assemblies 1231, a third support 1232, and a pair of second shear plates 1233.

[0069] Among them, the top of the third support 1232 is connected to the machine room chassis body 110 in the vertical direction through a plurality of third bolt assemblies 1231, and the bottom of the third support 1232 is used to connect to the rear girder 200.

[0070] A pair of second shear plates 1233 are respectively connected to both sides of the third support 1232 in the horizontal second direction, and their tops are connected to the bottom of the machine room chassis body 110.

[0071] Among them, the second shear plate 1233 is used to restrain the machine room chassis body 110 from sliding in the horizontal second direction during the operation of the mechanism.

[0072] Specifically, a third connection assembly 123 is provided at the bottom of the machine room chassis body 110 to connect the rear girder 200. Among them, the second shear plates 1233 are respectively connected to both sides of the third support 1232 in the second direction of the third connection assembly 123 to resist the sliding of the machine room chassis body 110 in the second direction during the operation of the mechanism.

[0073] It should be noted here that the first direction and the second direction are perpendicular to each other. The first direction and the second direction can be the running directions of the trolley and the gantry on the crane respectively. The first direction and the second direction in which the machine room chassis body 110 may slide are limited and fixed, effectively improving the connection stability of the machine room chassis body 110 and extending the service life of the device.

[0074] In some embodiments, there are at least a pair of the third connection assemblies 123, and a pair of the third connection assemblies 123 are respectively arranged on both sides of the bottom of the machine room chassis body 110.

[0075] Specifically, for example, as Figure 2 shown, the third connection assemblies 123 are respectively arranged on both sides of the bottom of the machine room chassis body 110 to connect the rear girder 200, so as to perform anti-slip fixation on both sides of the machine room chassis body 110 in the second direction, which is stable and reliable.

[0076] It should be noted here that the second connection assembly 122 and the third connection assembly 123 in the present invention can be arranged either between the first connection assemblies 121 on the machine room chassis body 110 or outside the first connection assemblies 121.

[0077] In some embodiments, as Figure 4 shown, the first bolt assembly 1211, the second bolt assembly 1221 and the third bolt assembly 1231 can all include: a bolt 300, a first nut 400, a second nut 500 and a pair of non-metallic elastic gaskets 600.

[0078] Among them, the bolt 300 passes through the tops of the respective supports and the bottom of the machine room chassis body 110 from bottom to top, its cap end abuts against the tops of the respective supports, and the other end extends out of the bottom of the machine room chassis body 110.

[0079] The first nut 400 is screwed onto the other end of the bolt 300 and abuts against the bottom of the machine room chassis body 110.

[0080] The second nut 500 is screwed onto the other end of the bolt 300 and abuts against the top of the first nut 400.

[0081] A pair of non-metallic elastic gaskets 600 are respectively sleeved between the cap end of the bolt 300 and the top of each support, and between the bottom of the machine room chassis body 110 and the bottom of the first nut 400.

[0082] Thus, by adding non-metallic elastic gaskets 600 to the bolt assembly, the pre-tightening force of the bolt 300 can be effectively reduced, and the vertical binding force between the machine room chassis body 110 and the rear girder 200 can be further enhanced. Additionally, adding the second nut 500 can prevent the first nut 400 from loosening.

[0083] Specifically, the non-metallic elastic gasket 600 can be selected as an elastic rubber part. This is because when an elastic rubber part is subjected to force, it can undergo a large reversible deformation, effectively absorbing external forces to reduce the pre-tightening force of the bolt 300, thereby improving the service life of the bolt 300.

[0084] The above is the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
