Description

Technical Field

[0001] This utility model belongs to the field of pipeline installation technology, specifically relating to a pre-positioning tool for pipeline installation. Background Technology

[0002] The main functions of water supply and drainage pipelines include providing buildings, public facilities, and industrial enterprises with the necessary domestic water, fire-fighting water, and production water, and ensuring the effective discharge of sewage, wastewater, or rainwater to maintain environmental hygiene and dryness and prevent flooding. When the main water supply and drainage pipelines are laid out in the underground parking lot within the residential area, they need to be connected to the discharge pipelines by fixing them to the ceiling. Fixing the main pipelines to the ceiling prevents interference and facilitates maintenance.

[0003] The main pipeline typically has a large radius and wall thickness. Although the main pipeline is welded in sections, the overall weight of each section is still considerable. Before installation, the main pipeline needs to be lifted and moved to a fixed area on the top surface for pre-positioning, and then raised using lifting equipment. During installation, the main pipeline is usually placed near the installation location, and two or more people work together to lift the pipeline to the corresponding area for positioning, using forklifts or other lifting equipment. This positioning and movement of the pipeline results in a high workload for the workers, and the heavy workload can easily cause slippage, leading to other safety hazards. Utility Model Content

[0004] The purpose of this invention is to provide a pre-positioning tool for pipeline installation, which can solve the above-mentioned technical problems.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] This utility model provides a pre-positioning fixture for pipe installation, including a base frame, a clamping assembly, and a side support assembly. A support shaft is rotatably mounted on one side of the base frame, and two slide rail shafts are mounted on the support shaft. The clamping assembly is disposed on the two slide rail shafts. Back support plates are mounted on the upper and lower sides of the slide rail shafts, and the side support assembly is disposed on the back support plates. A top plate is installed between the upper sides of the two slide rail shafts, and an electric hoist is mounted on the top plate for lifting the clamping assembly to move along the slide rail shafts. A brake support plate is installed on the bottom surface of the base frame away from the support shaft, and a moving wheel is installed on the other side of the bottom surface of the base frame.

[0007] The ferrule assembly includes a lifting sleeve plate, a sliding seat, a push spring, and a bottom support plate. The sliding seat and the lifting sleeve plate are distributed vertically and slidably mounted on two slide rail shafts. The push spring is disposed between the lifting sleeve plate and the sliding seat and is sleeved on the slide rail shaft. Two fixing plates are mounted on the side of the lifting sleeve plate. The bottom support plate is mounted on the lower side of the two fixing plates. A pressure plate mounted on a rotating shaft is disposed above the bottom support plate. A connecting plate is disposed on the side of the bottom support plate.

[0008] The other side of the base plate is formed with a locking groove, and a locking plate is fitted into the locking groove. The locking plate is installed on the side of the connecting plate.

[0009] Using the aforementioned pre-positioning fixture for pipe installation, the base frame is moved to the vicinity of the pipe, and the clamping assembly is lowered to the ground. The inserting plate on the connecting plate is pressed down to disengage from the clamping groove. Then, the lower clamping plate is rotated upward to disengage from the closed state of the bottom support plate. The pipe is then rolled onto the bottom support plate, and the lower clamping plate is rotated in the opposite direction to clamp onto the pipe. At the same time, the connecting plate drives the inserting plate to rotate and clamp into the clamping groove, thereby forming a surrounding clamping state for the pipe by the lower clamping plate, the fixing plate, and the bottom support plate. Then, the push-pull shaft on the side support assembly is pulled, which drives the slide rail shaft and the pipe on the clamping assembly to be lifted. At the same time, the side support shaft on the side support assembly is adjusted to drive the reinforcing plate to be inserted into the groove, thereby providing support for the slide rail shaft which is in an inclined state. Then, the clamping assembly is lifted and adjusted using an electric hoist. This facilitates the lifting and moving operation for pre-positioning, thereby improving the auxiliary effect of pre-positioning.

[0010] Preferably, the side support assembly includes a push-pull shaft, a side support shaft, and a reinforcing plate. The sides of the two back support plates are detachably mounted with fixed seats. The two sides of the push-pull shaft are mounted on the two fixed seats. A rotating sleeve is rotatably mounted on the push-pull shaft. The number of side support shafts is set to two, and the upper side of both is mounted on the rotating sleeve. The reinforcing plate is mounted on the lower side of the two side support shafts.

[0011] Preferably, a fixing ring is installed on the other side of the lifting sleeve plate for fixing the lifting chain of the electric hoist.

[0012] Preferably, a recessed groove is formed on the upper surface of the bottom frame away from the support shaft. The recessed groove corresponds to the position of the reinforcing plate and is inserted into it. The opposite sides of the interior of the recessed groove are equipped with blocks to be stuck between the two side support shafts and to block the reinforcing plate.

[0013] Preferably, the inner side of the sink is provided with a side groove corresponding to the upper side of the support shaft, which is used to engage the side support shaft of the inclined support.

[0014] The beneficial effects are:

[0015] This utility model utilizes a base frame, a slide rail shaft, a clamping assembly, an electric hoist, and a side support assembly. The clamping assembly can clamp and fix the pipe, and then the support shaft on the slide rail shaft is rotated to connect the pipe. The side support assembly is used to restrain the lifted pipe above the base frame. Finally, the electric hoist is used to lift the clamping assembly and the pipe, which facilitates lifting and raising the pipe and improves the pre-positioning adjustment effect during pipe installation.

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] like Figure 1-4As shown, a pre-positioning fixture for pipe installation includes a base frame 1, a clamping assembly 4, and a side support assembly 6. A support shaft 2 is rotatably mounted on one side of the base frame 1, and two slide rail shafts 3 are mounted on the support shaft 2. The clamping assembly 4 is disposed on the two slide rail shafts 3. Back support plates 5 are mounted on the upper and lower sides of the slide rail shafts 3. The side support assembly 6 is disposed on the back support plate 5. A top plate 7 is installed between the upper sides of the two slide rail shafts 3. An electric hoist 8 is mounted on the top plate 7 for lifting the clamping assembly 4 to move along the slide rail shafts 3. A brake support plate 9 is installed on the bottom surface of the base frame 1 away from the support shaft 2, and a moving wheel 10 is installed on the other side of the bottom surface of the base frame 1. The base frame 1 is configured as a concave shape.

[0024] The ferrule assembly 4 includes a lifting sleeve plate 41, a sliding seat 42, a push spring 43, and a bottom support plate 48. The sliding seat 42 and the lifting sleeve plate 41 are distributed vertically and are slidably mounted on two slide rail shafts 3. The push spring 43 is located between the lifting sleeve plate 41 and the sliding seat 42 and is sleeved on the slide rail shaft 3. Two fixing plates 47 are mounted on the side of the lifting sleeve plate 41. The bottom support plate 48 is mounted on the lower side of the two fixing plates 47. A lower pressure plate 45 mounted on a rotating shaft 44 is provided above the bottom support plate 48. The lower pressure plate 45 is L-shaped. A connecting plate 46 is provided on the side of the bottom support plate 48. The bottom support plate 48 is notched.

[0025] The other side of the base plate 48 is formed with a snap-fit ​​groove 48a, and a snap-fit ​​plate 46a is snapped into the snap-fit ​​groove 48a. The snap-fit ​​plate 46a is installed on the side of the connecting plate 46.

[0026] As an optional implementation, the side support assembly 6 includes a push-pull shaft 61, a side support shaft 63, and a reinforcing plate 64. The sides of the two back support plates 5 are detachably mounted with fixed seats. The two sides of the push-pull shaft 61 are mounted on the two fixed seats. A rotating sleeve 62 is rotatably mounted on the push-pull shaft 61. The number of side support shafts 63 is set to two, and the upper side of both is mounted on the rotating sleeve 62. The reinforcing plate 64 is mounted on the lower side of the two side support shafts 63. This arrangement enables the push-pull shaft 61 to provide hand grip support when the back support plate 5 and the slide rail shaft 3 drive the sleeve assembly 4 to flip and lift.

[0027] See attached document Figure 2 A fixing ring is installed on the other side of the lifting sleeve plate 41 to fix the lifting chain of the electric hoist 8. This setting allows the electric hoist 8 to drive the entire sleeve assembly 4 to move along the slide rail shaft 3, thereby achieving the lifting effect.

[0028] Furthermore, a recess 1a is formed on the upper surface of the bottom frame 1 away from the support shaft 2. The recess 1a corresponds to the position of the reinforcing plate 64 and is inserted into it. The inner opposite sides of the recess 1a are equipped with a stop block 1c, which is used to lock between the two side support shafts 63 and block the reinforcing plate 64. This setting allows the stop block 1c to form a clamping state on the reinforcing plate 64 under the two side support shafts 63, thereby facilitating the flipping restriction of the tilted slide rail shaft 3 and back support plate 5. When the fixture is lifted and moved on one side, it prevents the pipe on the sleeve assembly 4 from driving the slide rail shaft 3 to rotate in the opposite direction.

[0029] Furthermore, a side groove 1b is formed on the inner side of the sink 1a corresponding to the upper side of the support shaft 2, which is used to engage the side support shaft 63 of the inclined support. This arrangement allows the inclined slide rail shaft 3 to engage with the side groove 1b, thereby ensuring that the side support shaft 63 can drive the reinforcing plate 64 to penetrate into the sink 1a to form an inclined support.

[0030] Using the above structure, in use, the bottom frame 1 is pushed to the vicinity of the pipe, and the clamping assembly 4 is lowered to the ground. The clamping plate 46a on the connecting plate 46 is pressed down to disengage from the clamping groove 48a. Then, the lower clamping plate 45 is rotated upward to disengage from the closed state of the bottom support plate 48. The pipe is then rolled onto the bottom support plate 48, and the lower clamping plate 45 is rotated in the opposite direction to clamp onto the pipe. At the same time, the connecting plate 46 drives the clamping plate 46a to rotate and clamp into the clamping groove 48a, thereby making the lower clamping plate 45 and the fixed... The fixed plate 47 and the bottom support plate 48 form a clamping state around the pipe. Then, the push-pull shaft 61 on the side support assembly 6 is pulled, which drives the pipe on the slide rail shaft 3 and the clamping assembly 4 to be lifted. At the same time, the side support shaft 63 on the side support assembly 6 is adjusted to drive the reinforcing plate 64 to be inserted into the sink 1a, thereby supporting the slide rail shaft 3 which is in an inclined state. Then, the clamping assembly 4 is lifted and adjusted by the electric hoist 8. This facilitates the lifting and moving operation of the pre-positioning, thereby improving the auxiliary effect of pre-positioning.
