Description

Technical Field

[0001] The present invention relates to the technical field of pipeline connection, in particular to a hydraulic pipeline connection device. Background Art

[0002] Pipeline connection refers to connecting prefabricated pipe sections into a complete system according to the requirements of the design drawings, and connecting two pipes together through pipe connecting joints to achieve the purpose of laying pipelines according to needs.

[0003] Patent publication number CN213512494U discloses a pipe connection assembly and a pipe connection device. The pipe connection assembly includes a connecting ring and a clamping ring. A plurality of compression plates are spaced apart on the inner circumference of the clamping ring. One end of the inner wall of the connecting ring is provided with a step portion. The clamping ring is disposed on the step portion, and the inner end of the compression plate extends inwardly beyond the inner edge of the step portion. The connecting ring of the pipe connection assembly is used to connect a pipe joint. The clamping ring is provided in the connecting ring. When the pipe is connected to the pipe joint, the compression plates on the inner circumference of the clamping ring can be pressed against the outer wall of the pipe, thereby gripping the pipe without locking the pipe. During the full filling test and the flexible seismic resistance test, the pipe and the pipe joint will not easily separate. When the pipe expands or contracts due to heat, the pipe and the clamping ring can move relative to each other, preventing the pipe from being damaged by pulling or squeezing forces.

[0004] The existing pipe connection joints have the following problems: when the pipe is in use with water, impurities in the pipe will accumulate at the connection joints. Long-term use may cause pipe blockage or reduce flow. Therefore, it is necessary to design a connection joint that can regularly inspect and discharge impurities from the pipe connection joints. Summary of the Invention

The movable plate is located on the movement trajectory of the connecting rod. At this time, the connecting rod is in a non-pullable state, which can prevent the connecting rod from being pulled open due to accidents after the maintenance personnel leave, thereby causing water leakage in the pipeline.

[0008] Preferably, the impurity removal device also includes two filter strips, which are respectively fixed on the inner wall of the connecting joint. The two filter strips have arc chamfers on one side close to the flange of the connecting joint. After water flows through the pipeline, the impurities in the incoming water are intercepted by the two filter strips arranged on the inner wall of the connecting joint, so as to prevent the liquid in the hydraulic pipeline from being blocked due to too many impurities during transportation.

At this time, the spring between the circular plate and the bottom of the cylinder is compressed, and the stop foot moves to the through groove opened on the surface of the cylinder. Through the spring provided between the stop foot and the column rod, the stop foot is popped out under the action of the spring force, and the new screw is stuck in the through hole of the flange, and then the ratchet is turned, and the new screw is fixed. In this way, the purpose of simplifying the fixation is achieved, a lot of time is saved for manual installation, and convenience is provided for the installer.

When there is a collision, the special-shaped baffle will push the ratchet plate, and the ratchet is located on the movement trajectory of the ratchet plate. The ratchet plate pushes the ratchet to rotate, so that the screw is fixed tighter, thereby avoiding the situation where ordinary screws will loosen due to collision, and reducing the possibility of water leakage at the connection.

[0013] The present invention provides a hydraulic pipeline connecting device having the following beneficial effects:

[0014] (1) The present invention uses the arrangement of a de-impurity device to coordinate two drain tubes, two water baffles, two valve housings and a connecting rod. When maintenance personnel conduct regular inspections, the impurities accumulated in the drain tubes can be flushed out by pulling the connecting rod, thereby achieving the purpose of regularly cleaning the impurities stored in the pipeline. By arranging the bracket, bolts and movable plate, the connecting rod is in an un-pullable state after the maintenance is completed, which can prevent the connecting rod from being pulled apart due to an accident after the maintenance personnel leave, thereby causing the pipeline to leak. By arranging the filter strips, impurities in the incoming water are intercepted, thereby preventing the liquid in the hydraulic pipeline from being blocked due to excessive impurities during transportation.

[0015] (2) The present invention uses the setting of the shockproof device to make the anti-collision shell and the special-shaped baffle cooperate, and absorb the vibration of the anti-collision shell through the spring, thereby reducing the vibration of the connection joint and slowing down the pulling of the connection joint by external force, thereby preventing the pipeline from breaking at the connection joint; through the setting of the oil tank and the switch, when there is a collision, the oil tank sprays out the engine oil from the oil injection port, which can prevent the paint at the pipeline connection from being damaged due to the collision, thereby preventing oxidation and rusting.

[0016] (3) The present invention achieves the purpose of simplifying the fixation by setting up the fixing device, so that the cylinder, the foot stop, the button, the column rod and the round plate are matched, which saves a lot of time for manual installation and provides convenience for the installers; at the same time, when there is a collision, the ratchet plate pushes the ratchet wheel to rotate, so that the screw is fixed tighter, thus avoiding the situation that ordinary screws will become loose due to collision and reducing the possibility of water leakage at the connection.

When the pipeline is installed, in order to facilitate installation, the new screw of the fixing device 4 is used for fixing. First, the cylinder 43 is passed through the through hole of the connecting flange. The circular plate 47 is slidably installed on the inner wall of the cylinder 43. The circular plate 47 is fixed to the bottom of the inner wall of the cylinder 43 by a spring. One end of the stop foot 44 is hinged to the side of the circular plate 47 away from the bottom of the cylinder 43.

The ratchet plate 41 pushes the ratchet 42 to rotate, so that the screw is fixed tighter, thereby avoiding the situation where ordinary screws will loosen due to collision, and reducing the possibility of water leakage at the connection.

[0034] When in use, after water flows through the pipeline, impurities in the incoming water are intercepted by the two filter strips 28 arranged on the inner wall of the connecting section 1, so as to prevent the liquid in the hydraulic pipeline from being blocked due to too many impurities during transportation; at the same time, the intercepted impurities flow into the filter cylinder 21 and accumulate. When the maintenance personnel conduct regular inspections, they unscrew the bolts 26, and the movable plate 27 hinged on the outer wall of the connecting section 1 can be opened freely. The connecting rod 24 is in a pullable state. The maintenance personnel pull the connecting rod 24, and the connecting rod 24 pulls the water baffle 22 , the water baffle 22 slides open inside the valve housing 23, and the water outlet channel of the valve housing 23 is opened. At this time, the impurities accumulated in the leak tube 21 will be flushed out by the water flow, thereby achieving the purpose of regularly cleaning the impurities stored in the pipeline; when the maintenance is completed, the connecting rod 24 can be pushed to close the water outlet channel.

[0035] Through the setting of the external anti-collision shell 31, under the action of the spring force, when an external force vertically hits the connecting joint 1, the vibration of the anti-collision shell 31 will be absorbed by the spring, thereby reducing the vibration felt by the connecting joint 1; through the setting of the special-shaped baffle 32, when an external force pulls the connecting joint 1 horizontally, under the action of the spring force, the pulling of the connecting joint 1 by the external force will be slowed down, thereby preventing the pipeline from breaking at the connecting joint 1; at the same time, when a collision occurs, the special-shaped baffle 32 will squeeze the oil tank 33, the oil tank 33 will squeeze the switch 34, and the switch 34 will touch the flange at the pipe connection, causing the oil tank 33 to spray oil from the oil spray port, thereby preventing the paint at the pipe connection from being damaged due to the collision, thereby preventing oxidation and rusting.

[0036] When the pipe is installed, in order to facilitate installation, the new screw of the fixing device 4 is used to fix it. First, the cylinder 43 is passed through the through hole of the connecting flange, and the button 45 is pressed. The button 45 pushes the column rod 46, and the column rod 46 pushes the circular plate 47. At this time, the spring between the circular plate 47 and the bottom of the cylinder 43 is compressed, and the blocking foot 44 moves to the through groove opened on the surface of the cylinder 43. Under the action of the spring force, the blocking foot 44 is ejected, and the new screw is stuck in the through hole of the flange. Then the ratchet 42 is turned, and the new screw is fixed tightly.
