Description

Technical Field

[0001] The invention relates to the technical field of building drainage pipe docking, in particular to a building drainage pipe docking structure. Background Art

[0002] Building drainage pipes are pipe systems used by urban buildings to discharge domestic sewage, rainwater and other wastewater. Two separate drainage pipes are usually butted together by means of a socket connection, and the two ends of the drainage pipe are respectively a plug-in end with a smaller diameter and a socket end with a larger diameter. During the butt installation, it is generally necessary to first install the rubber sealing ring in the annular groove on the inner side of the socket end of the rear drainage pipe, and then evenly apply lubricating oil for reducing friction on the outer wall of the plug-in end of the front drainage pipe, the socket end of the rear drainage pipe and the inner wall of the sealing ring, and finally insert the plug-in end of the front drainage pipe backwards into the socket end of the rear drainage pipe until the predetermined depth is reached.

[0003] In the prior art, since the rubber sealing ring itself generally has a certain tension to ensure that it can be stably inserted into the annular groove, the sealing ring will usually be twisted during transportation and it is difficult to maintain a standard circular ring shape, and it is also difficult for operators to directly insert the circular ring-shaped sealing ring into the annular groove on the inner side of the receiving end. Therefore, in the process of installing the sealing ring, not only does the operator need to manually open the twisted sealing ring gradually outward until it is completely inserted into the annular groove, but the operator also needs to constantly maintain the shape of the sealing ring to prevent it from twisting and deforming again due to its own tension; since the drainage pipe on the rear side is generally placed on the ground, the drainage pipe hoisted on the front side also needs to be placed on the ground before docking to ensure that its plug-in end and the receiving end of the rear drainage pipe can be roughly aligned, and then the plug-in end of the front drainage pipe on the ground is inserted into the receiving end of the rear drainage pipe by manually cooperating with the lifting rope.

[0004] However, the traditional method of connecting drainage pipes through socket-type connection has the following problems: 1. The operation method of installing the sealing ring is relatively cumbersome, time-consuming and labor-intensive, which not only leads to a low overall installation efficiency of the sealing ring, but also causes a heavy overall operation burden on the operators to install the sealing ring when docking more drainage pipes, and the labor cost is high, which in turn affects the overall docking and installation operation of the drainage pipe; 2. Since the overall weight of the drainage pipe is heavy and in direct contact with the ground, the method of manually pushing the drainage pipe with the help of the lifting rope will cause the lifting rope in direct contact with the ground and the plug-in end of the front drainage pipe to be more easily worn under the action of friction, which not only leads to a significant impact on the safety of the use of the lifting rope during the lifting process and the service life of the overall operation process, but also may affect the sealing effect of the plug-in end of the front drainage pipe and the overall stability of the building drainage pipe system. At the same time, the friction between the front drainage pipe and the ground will also cause the overall operation burden of the operators to push and align the drainage pipe to be heavy, further increasing the overall labor cost.

[0032] See also Figure 1 , Figure 2 and Figure 3 The axial moving part 22 includes a U-shaped handle 221 symmetrically fixed on the front moving cart 1, an oil storage bucket 222 located between the horizontal connecting rods 21 is fixedly provided on the rear side of the front moving cart 1 through a connecting rod, and an oil storage bucket 223 is fixedly provided on the front side of the rear moving cart 1 through an L-shaped support frame.

[0033] See also Figure 2 and Figure 3 The supporting part 23 includes a supporting rod 231 which is symmetrically fixed on the upper side of the mobile cart 1, and an arc-shaped supporting plate 232 is fixedly provided on the upper ends of the symmetrical supporting rods 231. A plurality of rollers 233 are provided on the upper side of the arc-shaped supporting plate 232 so as to rotate evenly left and right through a support.

[0034] See also Figure 1 , Figure 2 and Figure 3The rotating driving part 24 includes two support rods 241 which are symmetrically fixed on the upper side of the mobile cart 1. An arc-shaped rotating frame 242 is fixedly provided on the upper ends of the two symmetrical support rods 241. A plurality of rollers 233 are also provided on the upper side of the arc-shaped rotating frame 242 so as to rotate evenly left and right through a second support. An arc-shaped rotating groove which passes through inside and outside is provided on the front side of the arc-shaped rotating frame 242. A rotating ring 243 is rotatably provided inside the arc-shaped rotating frame 242. A notch is provided on the upper side of the rotating ring 243. The rotating ring 243 and the lower side of the arc-shaped rotating frame 242 are positioned by docking with a latch.

[0035] When the two drainage pipes on the front and rear sides are to be connected, the straight pipe on the rear side of the receiving end of the rear drainage pipe is first supported by the roller 233 on the upper side of the rear arc-shaped supporting plate 232 and the arc-shaped rotating frame 242, and then the sealing ring is installed in the annular groove inside the receiving end of the rear drainage pipe through the inner support mechanism 3. Then, the plug-in end of the front drainage pipe is placed on the roller 233 on the upper side of the front arc-shaped supporting plate 232 and the arc-shaped rotating frame 242 through the lifting rope, so that the plug-in end of the front drainage pipe and the receiving end of the rear drainage pipe are stably aligned, and the lubricating oil for reducing friction is evenly applied to the outer wall of the plug-in end of the front drainage pipe, the receiving end of the rear drainage pipe and the inner wall of the sealing ring through the coating mechanism 4. At this time, the plug-in end of the front drainage pipe can be stably inserted backward into the receiving end of the rear drainage pipe by manual cooperation with the lifting rope.

[0036] When the two drainage pipes on the front and rear sides are connected and installed, the rotating ring 243 is first connected and positioned with the corresponding arc-shaped rotating frame 242 through the latch, so that the notch on the upper side of the rotating ring 243 is aligned with the vertical section of the lifting rope. At this time, the two front and rear symmetrical moving carts 1 are pulled forward through the U-shaped handle 221, and the moving cart 1 drives the corresponding arc-shaped supporting plate 232 and the rotating ring 243 in the arc-shaped rotating frame 242 to move forward synchronously until the rear arc-shaped supporting plate 232 and the rollers 233 on the upper side of the arc-shaped rotating frame 242 move and support to the bottom of the rear straight pipe of the front drainage pipe receiving end. At this time, the lifting rope of the front drainage pipe can be released, and the plug-in end of the new drainage pipe to be connected can be hoisted and placed on the front arc-shaped supporting plate 232 and the rollers 233 on the upper side of the arc-shaped rotating frame 242.

[0037] It should be noted that in order to make the drainage pipe have a certain inclination and ensure the smoothness of drainage, it is often necessary to raise the drainage pipe through a pad. Therefore, after the drainage pipe on the rear side loses the support of the supporting part 23, it will be supported by the pad, thereby avoiding excessive height difference between the front and rear drainage pipes and affecting the connection effect.

[0038] The above-mentioned operation method can realize the stable alignment and support of the plug-in ends and the receiving ends of the front and rear drainage pipes respectively, thereby not only avoiding the wear of the lifting rope and the plug-in end of the front drainage pipe due to ground friction during the docking installation process, but also greatly reducing the overall workload of manually pushing and aligning the drainage pipes during the docking operation.

[0039] See also Figure 1 The inner support mechanism 3 includes a rotating seat 31 fixedly arranged on the left side of the rear arc-shaped rotating frame 242, the rotating seat 31 is provided with an angle adjustment part 32, the angle adjustment part 32 is provided with a telescopic driving part 33, and the telescopic driving part 33 is provided with an inner support part 34 for quickly opening the sealing ring.

[0040] See also Figure 1 , Figure 5 and Figure 6 The angle adjustment portion 32 includes a lower baffle 321 fixedly arranged on the lower side of the front surface of the swivel seat 31, an upper baffle 322 fixedly arranged on the upper side of the rear surface of the swivel seat 31, an adjustment rod 323 movably arranged on the swivel seat 31, a front positioning plate 324 fixedly arranged on the adjustment rod 323 and positioned in front of the swivel seat 31 and matched with the upper surface of the lower baffle 321, and a rear positioning plate 325 fixedly arranged on the adjustment rod 323 and positioned in the rear of the swivel seat 31 and matched with the lower surface of the upper baffle 322.

[0041] See also Figure 1 and Figure 5 The telescopic driving part 33 includes a connecting plate 1 fixedly arranged at the front end of the adjusting rod 323, a limiting cover 331 is fixedly arranged at the right end of the connecting plate 1, a plurality of limiting slides 332 are evenly fixedly arranged on the rear side of the limiting cover 331 in the circumferential direction, a linear groove running through the front and back is opened on the limiting slide 332, a driving column 333 that moves forward and backward is slidably arranged in the limiting cover 331, and a return handle 334 is fixedly arranged at the front end of the driving column 333.

[0042] By moving the adjustment rod 323 backward and rotating it in a certain direction, the lower surface of the front positioning plate 324 can be stably fitted on the upper surface of the lower baffle plate 321, and the adjustment rod 323 can no longer rotate in the same direction and is temporarily positioned under the gravity of the connecting plate 1 and the limiting cover 331. At this time, by moving the adjustment rod 323 forward and rotating it 180 degrees in the opposite direction, the upper surface of the rear positioning plate 325 can be stably fitted on the lower surface of the upper baffle plate 322, and the adjustment rod 323 can no longer rotate and is temporarily positioned under the gravity of the connecting plate 1 and the limiting cover 331 again.

[0043] See also Figure 1 and Figure 5The inner support portion 34 includes a plurality of driven plates 341 that are uniformly arranged circumferentially on the rear side of the limiting cover 331 and correspond to the limiting slide 332 one by one. A T-shaped sliding shaft 342 that slides in cooperation with the linear groove on the corresponding limiting slide 332 is fixedly arranged on the front side of the driven plate 341 through a support three. The driven plate 341 is hinged to the driving column 333 through a transmission rod distributed front and back. An inner support plate 343 is fixedly arranged on the rear side of the driven plate 341 through a connecting plate two. The inner support plate 343 is composed of a horizontal plate and an inclined plate distributed front and back. A clamping plate 344 is fixedly arranged on the front end of the inner support plate 343 away from the driving column 333.

[0044] When the straight pipe at the rear side of the rear drainage pipe receiving end is stably supported by the rear arc-shaped supporting plate 232 and the roller 233 on the upper side of the arc-shaped rotating frame 242, the twisted sealing ring is first sleeved on the outer side of the horizontal plate on the inner support plate 343, and the inclined plate on the inner support plate 343 can facilitate the sealing ring to be sleeved, and then the adjusting rod 323 is rotated in a directional manner until the sealing ring is aligned with the receiving end of the rear drainage pipe, and then the adjusting rod 323 drives the front positioning plate 324 to move backward and fit the upper surface of the lower baffle plate 321, and the limiting cover 331 cannot continue to rotate and is temporarily positioned. At the same time, the limiting cover 331 drives the sealing ring to move synchronously to the inside of the receiving end of the rear drainage pipe through the inner support plate 343 and the abutting plate 344 thereon, until The sealing ring is aligned with the annular groove. At this time, the driving column 333 is driven to move backward through the return handle 334, and the driving column 333 then drives the driven plate 341 and the T-shaped slide shaft 342 thereon to move along the linear groove on the corresponding limiting slide seat 332 in the direction away from the driving column 333 through the transmission rod. The driven plate 341 then drives the inner support plate 343 to move synchronously and quickly and evenly stretch the sealing ring on its outer side to connect it into the annular groove. The above-mentioned operation method can quickly stretch the twisted sealing ring from the inside to the outside and stably connect it into the annular groove, which not only greatly simplifies the overall operation of the sealing ring installation, but also greatly reduces the overall operation burden of the operator in installing the sealing ring, further reducing the overall labor cost.

[0048] When the plug-in end of the front drainage pipe is placed on the roller 233 on the upper side of the front arc-shaped supporting plate 232 and the arc-shaped rotating frame 242 by the lifting rope, the outer brush head 423 is pressed against the outer wall of the plug-in end of the front drainage pipe under the action of the corresponding spring rod 422. At this time, the front rotating ring 243 is rotated to make the outer brush head 423 rotate continuously along the outer wall of the plug-in end of the front drainage pipe to apply lubricating oil.

[0049] When the lubricating oil on the outer brush head 423 needs to be replenished, first pour the lubricating oil into the oil storage bucket 222, then pull the elastic sliding sleeve 412 backward to drive its corresponding insertion rod 413 to disengage from the corresponding insertion hole, then drive the fixed slide 421 and its corresponding outer brush head 423 to rotate one hundred and eighty degrees through the rotating sleeve 414, then loosen the elastic sliding sleeve 412 to insert the insertion rod 413 into the corresponding insertion hole again to stably position the rotating sleeve 414 and the fixed slide 421, and finally rotate the front rotating ring 243 again to rotate the outer brush head 423 to the lowermost oil storage bucket 222, thereby replenishing the lubricating oil on the outer brush head 423.
