[0028] Example 1

[0029] Please see Figures 1 to 8 The present invention preferably provides the following technical solution: a multi-scenario combined cantilever crane, the cantilever crane including a first crossbeam 116, a second crossbeam 211 and a third crossbeam 411 assembled in sequence, and an electric hoist lift 311 that moves horizontally along the first crossbeam 116, the second crossbeam 211 and the third crossbeam 411; the ends of the first crossbeam 116 and the second crossbeam 211 away from the third crossbeam 411 are respectively vertically equipped with outrigger rod support frames, and a connecting strip assembly is provided at the end of the third crossbeam 411 away from the second crossbeam 211; when the cantilever crane is assembled on the vehicle body, the outrigger rods and support frames work and are connected to the vehicle body; when the cantilever crane is assembled under the vehicle, the support frames and connecting strip assembly work and are connected to the vehicle body.

[0030] Through the assembly design of the cantilever crane, the combined assembly of the first crossbeam 116, the second crossbeam 211 and the third crossbeam 411 can be applied in many occasions. The electric hoist lift 311 is an existing mature technology used for suspension on construction sites.

[0031] like Figure 5 and 6 As shown, when the cantilever crane is applied to the vehicle body, specifically, a support plate 6112 is placed horizontally on the carriage 611, and a second plug sleeve 6111 is fitted on its side wall. The outrigger rod is assembled with the second plug sleeve 6111, and the support frame is supported and erected on the support plate 6112, so that the cantilever crane and the vehicle body can be assembled, which facilitates the transfer during engineering operations.

[0032] like Figure 7 , 8 As shown, when the cantilever crane is applied to the railway track, that is, when the first plug sleeve 5111 is assembled on the track body 511, the outrigger rod is assembled with the first plug sleeve 5111, and the support frame is supported and erected on the ground, it can be assembled on the railway track to facilitate on-site suspension operation.

[0033] like Figure 4 As shown, when the cantilever crane is operating under the vehicle, the connecting strip assembly where the third crossbeam 411 is located can be connected to the side wall of the vehicle body, and the support frame at the other end of it is supported on the ground, so that items between the vehicle body and the ground can be suspended and transferred, realizing the combined use in multiple occasions, that is, one machine for multiple purposes.

[0034] Example 2

[0035] In another embodiment of the present invention, the outrigger rod includes a first mounting sleeve 111, a first support rod 112 that can move up and down is installed inside the first mounting sleeve 111, the first support rod 112 is fixed to the bottom end of the first crossbeam 116, and a first locking bolt 113 is provided on the first mounting sleeve 111 for locking the height of the first support rod 112.

[0036] Furthermore, the bottom of the first mounting sleeve 111 is sequentially connected to a step portion 1141 and a plug post 114, the area of ​​the step portion 1141 being larger than the area of ​​the plug post 114, and a first pin 115 penetrating the lower part of the plug post 114; as well as a first plug sleeve 5111 and a second plug sleeve 6111 that are plugged into and adapted to the plug post 114.

[0037] like Figure 1 and 2 As shown, the telescopic arrangement of the first mounting sleeve 111 and the first support rod 112 allows the height of the cantilever crane to be adjusted. Simultaneously, because the height of the first support rod 112 is adjustable, when the cantilever crane operates on the vehicle body or railway track, after the support frame provides stable support, the outrigger rods can be inserted into the first insertion sleeve 5111 and the second insertion sleeve 6111 at different positions by adjusting their height.

[0038] Through further configuration of the insert post 114 and the stepped portion 1141, such as Figure 7 ,8 As shown, the step portion 1141 can be supported on the top of the first plug sleeve 5111. When the first pin 115 is inserted into the plug post 114 and placed at the lower part of the first plug sleeve 5111, the first mounting sleeve 111 can be limited and locked on the first plug sleeve 5111. Similarly, the first mounting sleeve 111 can be assembled on the second plug sleeve 6111 where the carriage 611 is located.

[0039] Furthermore, the support frame includes a bracket 212 and a second mounting sleeve 213 fixed on the bracket 212. The second mounting sleeve 213 is equipped with a second support rod 215 that can move up and down. The top of the second support rod 215 is fixed to the bottom end of the second crossbeam 211, and a second locking bolt 214 is provided on the second mounting sleeve 213 for locking the height of the second support rod 215.

[0040] Furthermore, the bracket 212 has a triangular structure and is placed parallel to the first support rod 112.

[0041] By setting up support frames, such as Figure 1 and 2 As shown, the second support rod 215 can be height adjusted relative to the bracket 212. In conjunction with the height adjustment of the outrigger rod, the overall suspension height can be adjusted. The triangular support structure of the bracket 212 can improve the stability of the support.

[0042] Example 3

[0043] In another embodiment of the present invention, the connecting strip assembly includes a vertical strip 412 and a plurality of through holes 413 formed on the vertical strip 412, wherein a second pin 414 is inserted laterally into one of the through holes 413.

[0044] In this embodiment, through the provided connecting strip component, such as Figure 1 , 4 As shown, by aligning the through hole 413 with the mounting hole of the assembly plate 6113 where the carriage 611 is located, and by inserting and limiting the second pin 414, one end of the cantilever crane can be mounted on the outer wall of the vehicle, and the other end can be supported on the ground by the support frame.

[0045] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part. Among these, there are various ways to install detachably, such as by using a combination of plug-in and snap-fit, or by using bolts for connection, etc.

[0046] In addition, all the connections / connections mentioned in the article do not refer to direct connection of components, but rather to the formation of a better connection structure by adding or removing connecting accessories according to the specific implementation situation.

[0047] The above description of the specific embodiments of this utility model is only used to further illustrate this utility model and should not be construed as limiting the scope of protection of this utility model.
