[0024] The following reference Figures 1 to 3 This application describes a bridge transfer machine support and a bridge transfer machine according to some embodiments.

[0025] This application provides a bridge transfer machine support for supporting the tail of a bridge transfer machine (hereinafter referred to as the transfer machine).

[0026] like Figure 1 and Figure 2 As shown, the bridge transfer machine support provided in this application includes a fixed frame assembly 13, a support frame 2, a support wheel 4, and a lifting drive device 3. The fixed frame assembly 13 is used to connect to the tail of the transfer machine, the support wheel 4 is used to support the ground, the support frame 2 has an extension direction along a first direction a, one end of the support frame 2 along the first direction a is hinged to the fixed frame assembly 13 through a first hinge shaft, and the other end of the support frame 2 along the first direction a is hinged to the wheel frame 5 of the support wheel 4 through a second hinge shaft; both the first hinge shaft and the second hinge shaft extend horizontally and are perpendicular to the first direction a.

[0027] One end of the lifting drive device 3 is a fixed end, and the other end of the lifting drive device 3 is a driving end. One of the fixed end and the driving end of the lifting drive device 3 is hinged to the support frame 2 through a third hinge shaft, and the other is hinged to the fixed frame assembly 13 through a fourth hinge shaft. Both the third hinge shaft and the fourth hinge shaft are parallel to the first hinge shaft.

[0028] The drive end of the lifting drive device 3 is telescopic, which drives the end of the support frame 2 connected to the fixed frame assembly 13 to rise and fall. This allows for adjustment of the height of the fixed frame assembly 13 to accommodate changes in the height of the tail of the transfer machine and the tail of the connected working equipment. It also provides support to the tail of the transfer machine, preventing the working equipment from shifting its center of gravity towards the tail due to the load on the tail of the transfer machine. This avoids affecting the overall performance, efficiency, and service life of the working equipment.

[0029] In one embodiment of this application, preferably, as shown below, Figure 2 As shown, the fixed frame assembly 13 includes a fixed frame 1, a rotating frame 7, and a slewing bearing 14. The fixed frame 1 is connected to the lower part of the tail of the transfer machine, and the rotating frame 7 is rotatably connected to the lower part of the fixed frame 1 through the slewing bearing 14, allowing the rotating frame 7 and the fixed frame 1 to swing relative to each other. This allows the fixed frame 1 to swing left and right along with the tail of the transfer machine and the working equipment when supporting the tail of the transfer machine and the working equipment.

[0030] In one embodiment of this application, preferably, the lifting drive device 3 is a hydraulic cylinder. The hydraulic cylinder can be connected to the hydraulic system so that the drive end of the hydraulic cylinder can extend and retract, thereby controlling the lifting of the fixed frame 1 and providing support force for the fixed frame 1, so that the fixed frame 1 can support the tail of the transfer machine and the working equipment at the required height.

[0031] In this embodiment, preferably, the bridge-type transfer conveyor support also includes an energy accumulator, which is installed on the support frame 2 and connected to the rodless chamber of the hydraulic cylinder. This allows the energy accumulator to provide a predetermined pressure, such as 8MPa to 10MPa, to the hydraulic cylinder to provide the required support force to the tail of the transfer conveyor. The support frame 2 and the fixed frame 1 can be automatically raised and lowered according to the height change of the tail of the transfer conveyor to meet the dynamic needs during the operation of the transfer conveyor, provide dynamic auxiliary support for the tail of the transfer conveyor, and also buffer the reaction force of the ground.

[0032] In this embodiment, preferably, the hydraulic cylinder is equipped with a balance valve, and the hydraulic cylinder is connected to the hydraulic system through the balance valve. When the hydraulic cylinder extends or retracts to the required height, the balance valve can prevent the hydraulic oil in the rodless chamber from returning to the hydraulic system. Then, the accumulator supplies oil to the hydraulic cylinder with a predetermined pressure, which can be adjusted automatically so that the hydraulic cylinder can adaptively extend or retract according to the change in the tail height of the transfer machine. It can also prevent the hydraulic oil in the rodless chamber from leaking out due to damage to the hydraulic pipeline, which would affect the operation of the equipment.

[0033] In one embodiment of this application, preferably, as shown below, Figure 2 and Figure 3As shown, an elastic buffer assembly 9 is also provided between the wheel frame 5 of the support wheel 4 and the support frame 2, so that when the support is transported with the transfer machine, the elastic buffer can absorb the force from the ground on the support wheel 4, so as to buffer the impact of the transfer machine on the uneven ground during transportation.

[0034] In this embodiment, preferably, as follows: Figure 2 and Figure 3 As shown, the bridge transfer machine support also includes a sliding bracket 8 and a support rod 6. The sliding bracket 8 is slidably mounted on the support frame 2 along a first direction a. For example, the support frame 2 has a groove, and the sliding bracket 8 is installed in the groove so that the sliding bracket 8 can slide on the support frame 2 along the first direction a. One end of the sliding bracket 8 faces the wheel frame 5 and is hinged to the wheel frame 5 through the support rod 6. That is, one end of the support rod 6 is hinged to the sliding bracket 8, and the other end of the support rod 6 is connected to the wheel frame 5. The hinge axes at both ends of the support rod 6 used to achieve the hinge are parallel to the axis of the support wheel 4. The end of the sliding bracket 8 away from the wheel frame 5 abuts against the support frame 2 through an elastic buffer assembly 9, so that the elastic buffer assembly 9 can provide an elastic force to the sliding bracket 8 along the first direction a. Therefore, when the support wheel 4 bounces up and down due to uneven ground, the support wheel 4 can transmit the force from the ground to the elastic buffer component 9 through the support rod 6 and the sliding bracket 8, so that the elastic buffer component 9 can play a shock absorption role and buffer the impact caused by uneven ground on the transfer machine during transportation.

[0035] In this embodiment, preferably, as follows: Figure 2 and Figure 3 As shown, the elastic buffer assembly 9 includes an elastic element 11 and a guide rod 10. The guide rod 10 is slidably disposed on the support frame 2 along a first direction a, and one end of the guide rod 10 abuts against one end of the sliding bracket 8. The elastic element 11 is sleeved on the guide rod 10, with one end of the elastic element 11 abutting against the guide rod 10 and the other end of the elastic element 11 abutting against the support frame 2. This allows the elastic element 11 to provide an elastic force along the first direction a to the sliding bracket 8, thereby buffering the impact of uneven ground on the support during transport by the transfer machine.

[0036] In this embodiment, preferably, as follows: Figure 2 and Figure 3As shown, the guide rod 10 has a positioning hole at one end facing the sliding bracket 8, and the sliding bracket 8 has a protrusion and a surrounding abutment at one end facing the guide rod 10. The guide rod 10 can be fitted into the positioning hole using the protrusion and abutted against the end of the guide rod 10 using the abutment. Preferably, the support frame 2 is also provided with a limiting block 12, which is located at the end of the sliding bracket 8 away from the guide rod 10. The sliding bracket 8 can slide away from the guide rod 10 under the elastic force of the elastic member 11 until it abuts against the limiting block 12. When the sliding bracket 8 abuts against the limiting block 12, the sliding bracket 8 and the guide rod 10 can remain in contact under the action of the elastic member 11. Thus, the limiting block 12 can ensure that the sliding bracket 8 and the guide rod 10 always remain in contact, preventing the sliding bracket from separating from the guide rod.

[0037] This application also provides a bridge transfer machine, including the bridge transfer machine support of any of the above embodiments.

[0038] In this embodiment, the bridge transfer machine includes a bridge transfer machine support, and therefore the bridge transfer machine has all the beneficial effects of the bridge transfer machine support, which will not be described in detail here.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
