Description

The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present disclosure, and cannot be understood as a limitation of the present disclosure. On the contrary, the embodiments of the present disclosure include all changes, modifications and equivalents falling within the spirit and scope of the appended claims.

[0031] As Figure 1 , Figure 2 and Figure 3 The present disclosure provides a grease pump supporting device for shield split launching, which comprises a first guide rail 1, a second guide rail 2 and a trolley 3.

The first walking wheel 32 and the second walking wheel 33 are respectively arranged on both sides of the frame 31, and the first walking wheel 32 and the first guide rail 1 are rollingly connected, and the second walking wheel 33 and the second guide rail 2 are rollingly connected.

[0032] It can be understood that, since the first walking wheel 32 and the second walking wheel 33 are arranged on both sides of the vehicle frame 31 respectively, and the first walking wheel 32 and the first guide rail 1 are rolling connected, and the second walking wheel 33 and the second guide rail 2 are rolling connected, the vehicle frame 31 can walk in the tunnel by the cooperation of the first walking wheel 32 and the first guide rail 1 and the cooperation of the second walking wheel 33 and the second guide rail 2, and since the vehicle frame 31 is connected with the shield main machine 100, and the first bearing surface on the vehicle frame 31 is arranged with at least one grease pump 200, the grease pump 200 for the main drive sealing lubrication of the shield main machine 100 and the tail shield grease can realize the follow-up of the shield main machine 100 by using the vehicle frame 31, thereby avoiding the problem of too long pipeline length between the shield main machine 100 and the grease pump 200 when starting separately, thereby realizing stable grease injection pressure of the grease pump 200, and further meeting the lubrication requirements of the shield main machine 100, and ensuring the safe and efficient operation of the shield main machine 100.

[0033] It should be noted that the first guide rail 1 is used to guide the first walking wheel 32, and since the first guide rail 1 has a detachable structure, the temporary arrangement of the grease pump 200 support device in the tunnel is more flexible and convenient, and the specific type of the first guide rail 1 can be set according to actual needs, which is not limited, for example, the first guide rail 1 can be a 100mm specification channel steel, the slot of the channel steel faces upward, and the wheel body of the first walking wheel 32 is rolling arranged in the slot of the first guide rail 1.

The horizontal frame 311 is arranged in a horizontal direction, and the first bearing surface is located on the horizontal frame 311.

The vertical frame 312 is arranged in a vertical direction on the side of the horizontal frame 311 away from the first walking wheel 32, and the second walking wheel 33 is arranged at the bottom of the vertical frame 312.

[0040] It can be understood that, since the first walking wheel 32 is arranged at the bottom of one side of the horizontal frame 311, and the vertical frame 312 is arranged in a vertical direction on the side of the horizontal frame 311 away from the first walking wheel 32, and the second walking wheel 33 is arranged at the bottom of the vertical frame 312, the “L” type support structure formed by the horizontal frame 311 and the vertical frame 312 can adapt to the tunnel structure with a circular cross section, so that the horizontal arrangement of the first bearing surface is realized, and the precise cooperation of the first walking wheel 32 and the first guide rail 1 and the second walking wheel 33 and the second guide rail 2 is ensured, thereby meeting the stable following of the grease pump 200 in the tunnel and the shield main machine 100.

The specific type of the vertical frame 312 can be set according to actual needs, and no limitation is made thereto.

[0043] As shown in Figure 2 and Figure 3As shown, in some embodiments, the vehicle frame 31 comprises a first longitudinal beam 313, a second longitudinal beam 314, a third longitudinal beam 315, a plurality of horizontal beams 316 and a plurality of vertical beams 317. Among them, the first longitudinal beam 313 and the second longitudinal beam 314 are arranged along the width direction of the tunnel, and the horizontal beams 316 are arranged between the first longitudinal beam 313 and the second longitudinal beam 314 along the width direction of the tunnel, and the plurality of horizontal beams 316 are distributed along the length direction of the tunnel, and the first longitudinal beam 313, the second longitudinal beam 314 and the plurality of horizontal beams 316 form a horizontal frame 311; the second longitudinal beam 314 and the third longitudinal beam 315 are arranged along the height direction of the tunnel, and the vertical beams 317 are arranged between the second longitudinal beam 314 and the third longitudinal beam 315 along the height direction of the tunnel, and the plurality of vertical beams 317 are distributed along the length direction of the tunnel, and the second longitudinal beam 314, the third longitudinal beam 315 and the plurality of vertical beams 317 form a vertical frame 312; the first walking wheel 32 is arranged at the bottom of the first longitudinal beam 313, and the second walking wheel 33 is arranged at the bottom of the third longitudinal beam 315.

[0044] It can be understood that, since the first longitudinal beam 313 and the second longitudinal beam 314 are arranged along the width direction of the tunnel, and the horizontal beams 316 are arranged between the first longitudinal beam 313 and the second longitudinal beam 314 along the width direction of the tunnel, and the plurality of horizontal beams 316 are distributed along the length direction of the tunnel, so that the first longitudinal beam 313, the second longitudinal beam 314 and the plurality of horizontal beams 316 can form a horizontal frame 311 for carrying the grease pump 200 and arranged horizontally; since the second longitudinal beam 314 and the third longitudinal beam 315 are arranged along the height direction of the tunnel, and the vertical beams 317 are arranged between the second longitudinal beam 314 and the third longitudinal beam 315 along the height direction of the tunnel, and the plurality of vertical beams 317 are distributed along the length direction of the tunnel, so that the second longitudinal beam 314, the third longitudinal beam 315 and the plurality of vertical beams 317 can form a vertical frame 312 for supporting the horizontal frame 311 and arranged vertically. Thus, through the cooperation of the first longitudinal beam 313, the second longitudinal beam 314, the third longitudinal beam 315, the plurality of horizontal beams 316 and the plurality of vertical beams 317, an "L"-shaped support structure is realized, thereby ensuring the stable arrangement of the grease pump 200 on one side of the tunnel.

[0045] It should be noted that the first longitudinal beam 313, the second longitudinal beam 314 and the third longitudinal beam 315 are the main beam bodies of the vehicle frame 31, and the specific type can be set according to actual needs, and this is not limited, for example, the first longitudinal beam 313, the second longitudinal beam 314 and the third longitudinal beam 315 are all beam body structures arranged along the length direction of the tunnel.

[0046] The cross beam 316 is arranged between the first longitudinal beam 313 and the second longitudinal beam 314 to form the cross frame 311 supporting the grease pump 200. The specific type of the cross beam 316 can be set according to actual needs, and no limitation is made thereto. For example, the cross beam 316 is a beam body structure arranged along the tunnel width direction. The number of the cross beam 316 can be two, three, four, five, six, etc.

[0047] The vertical beam 317 is arranged between the second longitudinal beam 314 and the third longitudinal beam 315 to form the vertical frame 312 supporting the cross frame 311.

[0048] The number of the cross beam 316, the vertical beam 317, the first walking wheel 32, the second walking wheel 33 and the grease pump 200 can be set according to actual needs, and no limitation is made thereto. For example, the cross beam 316 and the vertical beam 317 are respectively set to four. The four cross beams 316 and the four vertical beams 317 are uniformly distributed along the length direction of the tunnel. Adjacent cross beams 316 form a support area. Three support areas are arranged with three grease pumps 200 respectively. The first walking wheel 32 and the second walking wheel 33 are respectively set to four. The positions respectively correspond to the four cross beams 316 and the four vertical beams 317 distributed along the length direction of the tunnel.

[0051] It can be understood that, since the first part and the second part are detachably arranged on one side of the tunnel along the tunneling direction of the tunnel in sequence, the first part and the second part can be independently used for guiding the first walking wheel 32. Specifically, when the first walking wheel 32 is rollingly connected with the first part, the first part plays a role of supporting and guiding the first walking wheel 32, and the second part can be disassembled. Similarly, when the first walking wheel 32 is rollingly connected with the second part, the second part plays a role of supporting and guiding the first walking wheel 32, and the first part can be disassembled.

[0052] That is, the first part and the second part can be alternately arranged along the length direction of the tunnel by disassembly and assembly while supporting and guiding the first walking wheel 32, so as to meet the continuous following of the grease pump 200 and the shield main machine 100, and the whole only needs to arrange the first part and the second part, the structure is simpler, which can not only reduce the influence of the supporting device on other facilities, but also effectively reduce the following cost of the grease pump 200.

Wherein, the second walking wheel 33 and the third part are rollingly connected, or the second walking wheel 33 and the fourth part are rollingly connected.

[0055] It can be understood that, since the third part and the fourth part are detachably arranged on one side of the tunnel along the tunneling direction of the tunnel, the third part and the fourth part can be independently used for guiding the second walking wheel 33. Specifically, when the second walking wheel 33 and the third part are rollingly connected, the third part supports and guides the second walking wheel 33, and the fourth part can be disassembled and assembled. Similarly, when the second walking wheel 33 and the fourth part are rollingly connected, the fourth part supports and guides the second walking wheel 33, and the third part can be disassembled and assembled.
