Description

Technical Field

[0001] The utility model belongs to the technical field of central swivel joints, and particularly relates to an installation structure of a central swivel joint. Background Technique

[0002] A central swivel joint is a special pipeline connection device, which is mainly applied to hydraulic or pneumatic machinery with rotary motion, used to connect pipelines of relatively fixed parts and rotating parts, thus avoiding the problem of pipeline entanglement during rotary motion when using hose connections. This kind of joint can, when the rotary support rotates, through its unique structural design, realize the relative motion between the housing and the internal mandrel, ensure that the oil channels of the housing and the corresponding mandrel always remain unblocked, and thus realize the continuous rotation of the pipeline.

[0003] At present, the general central swivel joint is fixed on the vehicle frame by bolts. When the central swivel joint fails and needs to be repaired, it is necessary to hoist the cab and also disassemble the pipeline, resulting in a long disassembly time, causing the excavator to stop working and reducing work efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to provide an installation structure of a central swivel joint, aiming to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution:

[0006] An installation structure of a central swivel joint, including a vehicle frame, a rotary lubricating oil sump cylinder is installed inside the vehicle frame, reinforcing ribs are arranged on the inner side of the rotary lubricating oil sump cylinder, and a fixing plate is fixedly installed at the bottom of the rotary lubricating oil sump cylinder.

[0007] As a preferred scheme of the utility model, four grooves and four convex plates are arranged inside the fixing plate, and clamping grooves are arranged on the surface of the convex plates.

[0008] As a preferred scheme of the utility model, a seat plate is arranged on the top of the fixing plate, and four clamping blocks are fixedly installed on the outer side of the seat plate. After the grooves and convex plates inside the fixing plate are combined with the seat plate, four arc-shaped holes appear below the central swivel joint, and the arc-shaped holes can effectively prevent the working part of the central swivel joint from being blocked by soil.

[0009] As a preferred scheme of the utility model, first threaded holes are opened inside both the convex plates and the clamping blocks, and first bolts are installed inside the first threaded holes. By removing the first bolts from the first threaded holes, the seat plate can be separated from the fixing plate, and at the same time, the clamping blocks can be separated from the clamping grooves. Rotate the seat plate to align the clamping blocks with the grooves, and the disassembly can be completed from below the vehicle frame.

[0010] As a preferred embodiment of the present utility model, two clamping posts are fixedly installed on the top of the seat plate, a backing plate is arranged on the top of the seat plate, and a central swivel joint is installed inside the backing plate. Through the settings of the seat plate, fixed plate and backing plate, while ensuring the normal operation of the swivel joint, the assembly component materials of the swivel joint are reduced, the installation process time of the swivel joint is greatly reduced, and the swivel joint can be disassembled from under the excavator frame during disassembly.

[0011] As a preferred embodiment of the present utility model, second threaded holes are respectively formed inside the seat plate and the backing plate, second bolts are installed inside the second threaded holes, and a through groove is formed inside the backing plate.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] Through the settings of the seat plate, fixed plate and backing plate, while ensuring the normal operation of the swivel joint, the assembly component materials of the swivel joint are reduced, the installation process time of the swivel joint is greatly reduced, and the swivel joint can be disassembled from under the excavator frame during disassembly. After the groove and convex plate inside the fixed plate are matched with the seat plate, four arc-shaped holes appear under the central swivel joint. Through the arc-shaped holes, the working part of the central swivel joint can be effectively prevented from being blocked by soil. Moreover, when the soil blockage needs to be repaired, only the seat plate needs to be rotated to remove the soil. By removing the first bolt from the first threaded hole, the seat plate can be separated from the fixed plate, and at the same time, the clamping block is separated from the clamping groove. Rotate the seat plate to align the clamping block with the groove, and the disassembly can be completed from under the frame. This disassembly method makes the maintenance of the swivel joint more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Embodiment

[0024] Referring to Figures 1-4 , which is the first embodiment of the present utility model. This embodiment provides an installation structure for a central slewing joint, including a vehicle frame 1. Inside the vehicle frame 1, a slewing lubricating oil sump cylinder 2 is installed. Inside the slewing lubricating oil sump cylinder 2, reinforcing ribs 3 are provided. At the bottom of the slewing lubricating oil sump cylinder 2, a fixing plate 4 is fixedly installed.

[0025] Specifically, four grooves 5 and four convex plates 6 are provided inside the fixing plate 4. On the surface of the convex plate 6, a clamping groove 7 is provided.

[0026] Furthermore, the firmness of the device can be improved through the reinforcing ribs 3 in the slewing lubricating oil sump cylinder 2.

[0027] Specifically, a seat plate 8 is provided on the top of the fixing plate 4. Four clamping blocks 9 are fixedly installed on the outside of the seat plate 8.

[0028] Furthermore, by clamping the clamping blocks 9 on the outside of the seat plate 8 inside the clamping grooves 7 of the convex plates 6, the firmness of the seat plate 8 fixed on the fixing plate 4 can be increased.

[0029] Specifically, first threaded holes 10 are provided inside both the convex plate 6 and the clamping block 9, and first bolts 11 are installed inside the first threaded holes 10.

[0030] Further, by installing the first bolt 11 inside the first threaded hole 10, the seat plate 8 is firmly fixed to the outside of the fixed plate 4.

[0031] Specifically, two clamping posts 12 are fixedly installed at the top of the seat plate 8. A backing plate 13 is arranged at the top of the seat plate 8, and a central swivel joint 14 is installed inside the backing plate 13.

[0032] Further, by aligning the through slot 17 on the backing plate 13 with the clamping posts 12 on the seat plate 8, the tightness of the connection between the backing plate 13 and the seat plate 8 is increased.

[0033] Specifically, second threaded holes 15 are formed inside both the seat plate 8 and the backing plate 13. Second bolts 16 are installed inside the second threaded holes 15, and a through slot 17 is formed inside the backing plate 13.

[0034] Further, by installing the second bolts 16 inside the second threaded holes 15, the backing plate 13 can be fixed to the seat plate 8.

[0035] During use, first align the through slot 17 on the backing plate 13 with the clamping posts 12 on the seat plate 8, install the second bolts 16 inside the second threaded holes 15 to fix the backing plate 13 to the seat plate 8. Then, clamp the clamping block 9 on the outside of the seat plate 8 into the slot 7 of the convex plate 6. Next, install the first bolt 11 inside the first threaded hole 10 to firmly fix the seat plate 8 to the outside of the fixed plate 4. The reinforcing ribs 3 in the rotary lubricating oil sump cylinder 2 can improve the firmness of the device. When disassembling the central swivel joint 14, first remove the first bolt 11 from inside the first threaded hole 10, which can separate the seat plate 8 from the fixed plate 4, and at the same time, the clamping block 9 separates from the slot 7. Then, rotate the seat plate 8 so that the clamping block 9 aligns with the groove 5, and the disassembly can be completed from below the frame 1.

[0036] To sum up: Through the settings of the seat plate 8, the fixed plate 4, and the backing plate 13, while ensuring the normal operation of the central swivel joint 14, the assembly component materials of the central swivel joint 14 are reduced, and the installation process time of the central swivel joint 14 is greatly reduced. It can be disassembled from below the excavator frame 1 during disassembly. After the groove 5 and the convex plate 6 inside the fixed plate 4 are matched with the seat plate 8, four arc-shaped holes appear below the central swivel joint 14. Through the arc-shaped holes, the working part of the central swivel joint 14 can be effectively prevented from being blocked by mud. Moreover, when the mud blockage requires repair, just rotate the seat plate 8 to remove the mud. By removing the first bolt 11 from inside the first threaded hole 10, the seat plate 8 can be separated from the fixed plate 4, and at the same time, the clamping block 9 separates from the slot 7. Rotating the seat plate 8 so that the clamping block 9 aligns with the groove 5 can complete the disassembly from below the frame 1. This disassembly method makes the maintenance of the central swivel joint 14 more convenient.
