Description

Technical Field

[0001] The invention relates to the technical field of building water supply and drainage pipe installation equipment, and in particular to a building water supply and drainage pipe supporting and hanging device. Background Art

[0002] Building water supply and drainage is an important pipeline component of the water circulation inside the building, including tap water pipelines, fire water pipelines and wastewater discharge pipelines. Among them, household pipelines are mostly buried, but the main pipeline can only be exposed and hidden by support due to its large size. That is, the water supply and drainage main pipeline is positioned, installed and supported by positioning brackets, and the pipe clamps on the positioning brackets are used to fix the position of the pipeline after the pipeline is connected.

[0003] However, in actual operation, there is often a certain error between the installation position and the design position, and the positioning bracket itself cannot change position after installation. In addition, the deadweight of the pipeline affects the concentricity of the docking, which makes the pipeline docking operation difficult, especially at the pipe docking at the bend, the position of the pipeline needs to be adjusted repeatedly, which is labor-intensive. At the same time, when loading the pipeline on the bracket, only rigid pushing and pulling can be used, and the hard friction between the outer wall of the pipeline and the positioning bracket will not only affect the appearance of the pipeline, but also reduce the life of the pipeline, thereby increasing the maintenance load in the later stage. Summary of the invention

The bottom end of the adjusting plate is connected to one end of the U-shaped rod that passes through the adjusting tube, and the other end of the U-shaped rod contacts the bottom end of the fastening bolt.

[0006] Preferably, the locking assembly comprises a plurality of locking cylinders embedded in the inner ring surface of the pressure ring, the inner top wall of the locking cylinder is connected to a locking plate airtightly arranged in the locking cylinder through a locking spring, and the locking plate is provided with a locking rod penetrating the locking cylinder and connected to the pressure plate; An airtight box is fixed on the ear plate of the pressure ring, a closed passage for fastening bolts to pass through is opened on the airtight box, and an airtight plate is airtightly arranged inside the airtight box, a circular ring is coaxially arranged above the closed passage, and a plurality of connecting rods penetrating into the airtight box and connected to the airtight plate are arranged at the bottom of the circular ring; The spaces above the locking plates in the locking cylinders and the spaces below the airtight plates in the airtight boxes are airtightly connected via the second arc tubes.

[0007] Preferably, the adjustment assembly further comprises a pressure-maintaining mechanism arranged on the support seat: comprising a limit frame arranged on the vertical portion of the vertical U-shaped rod and fixedly connected to the outer wall of the support seat, the limit frame being provided with a slider for sliding toward one end of the support seat, and a limit spring being arranged between the slider and the limit frame; The sliding block and the U-shaped rod are respectively hinged to the pins at both ends of the hinged rod.

[0008] Preferably, the sliding block is provided with a limiting rod at one end facing the supporting seat, and a hinged seat hinged to the hinged rod at the other end; and a limiting hole for inserting the limiting rod is preset on the supporting seat.

[0009] Preferably, the hanging frame includes a hanging rod, a frame plate fixed at the top of the hanging rod, and a mounting plate fixed at the bottom of the hanging rod and provided with a through hole; a fine-tuning screw fixed on the support seat plate passes through the through hole and is connected to a nut.

[0010] Preferably, the top end of the U-shaped rod is rotatably connected to a contact plate.

[0011] Preferably, a pressure gauge is provided on the surface of the second arc tube.

[0012] Preferably, both the support seat and the pressure ring are provided with mounting pads, and the mounting pads are rubber material components.

[0013] Preferably, the mounting pad is provided with a plurality of through holes, and the plurality of through holes provide movement channels for the receiving pulley seat and the pressure plate.

[0014] The working process of the present invention is as follows: The frame plate of the support and suspension rod is installed on the building surface, and then the seat plate of the support seat and the mounting plate of the support and suspension rod are connected by adjusting bolts. At the same time, the limit rod of the pressure-maintaining mechanism is kept plugged into the limit hole on the support seat under the action of the limit spring, and in this state, the U-shaped rod is forced to remain at the highest point of the stroke relative to the support seat, so that the U-shaped rod will drive the adjustment plate to the top of the adjustment cylinder, and then the air in the adjustment cylinder enters the receiving cylinder through the first arc tube, and at the same time, the receiving plate exposes the receiving pulley seat to the outside of the support seat through the receiving rod.

[0015] Then, fix and dock the pipes: First, pass the fastening bolts through the closed channels of the circular ring and the airtight box in sequence, and then screw them into the preset screw holes on the ear plate. When the fastening bolts move down to the bottom end and touch the contact plate, it will drive the contact plate to rotate and press down the U-shaped rod at the same time. The downward movement of the U-shaped rod will drive the adjustment plate to move down, thereby allowing the air in the receiving tube to flow back into the adjusting tube, so that the receiving pulley seat retracts into the receiving seat, so that the pipeline is borne by the inner ring surface of the support seat. Then the pipeline can be docked and the height of the pipeline can be fine-tuned by adjusting the connection between the fine-tuning screw and the nut.

[0016] After the pipeline is docked, continue to turn the fastening bolt. When the bolt cap of the fastening bolt presses down the ring, the air in the airtight box will be pressed into the locking cylinder through the airtight plate through the second arc tube, so that the locking plate and the locking rod push the pressure plate toward the pipeline for crimping and locking the pipeline. The staff can observe the corresponding pressure through the pressure gauge on the second arc tube and adjust the position of the fastening bolt. During later disassembly and maintenance, as long as the fastening bolt no longer presses the ring, the locking spring can drive the locking plate to reset and push the air back into the airtight box.

[0017] Compared with the prior art, the present invention has the following advantages: 1) The adjustment assembly of the present invention can use the receiving pulley seat to reduce the friction between the water supply and drainage pipe and the support seat when the water supply and drainage pipe is docked and debugged, making it more convenient to adjust the water supply and drainage pipe, and can better complete the connection of adjacent water supply and drainage pipes, reducing the difficulty of installation. When installing the fastening bolts, its moving trajectory automatically completes the storage of the receiving pulley seat. During fixed installation, the receiving pulley seat will not contact the water supply and drainage pipe, ensuring the stability of the water supply and drainage pipe after installation, making debugging and installation more convenient, reducing the difficulty of installation and improving installation accuracy. At the same time, the mutual cooperation between the limit rod and the limit hole can increase the stability of the receiving pulley seat in the adjustment state, and it is not easily affected by the gravity of the water supply and drainage pipe, which increases the stability during adjustment; 2) The locking assembly of the present invention can automatically operate when the fastening bolt is locked along the track, stably locking the water supply and drainage pipe between the support seat and the pressure ring, avoiding the problem that the installation gap affects the stability of the water supply and drainage pipe. At the same time, under the cooperation of the pressure discharge box, the pressure discharge plate and the exhaust hole, the constant pressure locking is automatically completed, so that the pressure of multiple pressure plates on the water supply and drainage pipe is consistent, increasing the stability of the locking.
