Meanwhile, the hydraulic oil in the first oil passing hole 101 may also enter the third oil passing hole 103, and because the third oil passing hole 103 is blocked by the sealing plug, the hydraulic oil in the third oil passing hole 103 may enter the second oil passing hole 102, and then flow into the hydraulic branch pipe from the second oil passing hole 102, and thus flow into another lifting cylinder.

Compared with the prior art that the hydraulic branch pipe is welded on the hydraulic main pipe, the three-way is formed at the joint of the hydraulic main pipe and the hydraulic branch pipe. In this embodiment, use oil circuit block 1 to replace the tee bend of easy fracture, no longer need repair welding the tee bend, oil circuit block 1 also can not appear leaking, easy dismouting between hydraulic pressure main pipe and the hydraulic pressure branch pipe simultaneously makes things convenient for the pipeline to overhaul.

It should be noted that only the first oil passing hole 101 is a through hole, and the second oil passing hole 102 and the third oil passing hole 103 are blind holes.

Preferably, the oil block 1 is made of 35 gauge forged steel in order to meet the high pressure and fatigue strength requirements.

Preferably, the oil block 1 is a rectangular block, and as seen in fig. 1, the length direction of the rectangular block forms a first direction, the width direction of the rectangular block forms a second direction, the thickness direction of the rectangular block forms a third direction, the first direction, the second direction and the third direction are perpendicular, the oil block 1 has a front surface, a back surface, a top surface, a bottom surface and two side surfaces, two ends of the first oil passing hole 101 are positioned on the front surface and the back surface of the oil block 1, the second oil passing hole 102 is arranged on the side surface of the oil block 1, and the third oil passing hole 103 is arranged on the top surface of the oil block 1. The first oil passing hole 101 penetrates the front and rear surfaces of the oil passage block 1 to form one first oil port on each of the front and rear surfaces. Referring again to fig. 7, the third oil passing hole 103 extends from the top surface of the oil block 1 toward the bottom surface of the oil block 1, the lower end of the third oil passing hole 103 communicates with the first oil passing hole 101, the third oil passing hole 103 forms a third oil port on the top surface of the oil block 1, and a sealing plug is installed in the third oil port. And the second oil passing hole 102 extends from the left side surface of the oil block 1 toward the right side surface of the oil block 1 until the second oil passing hole 102 communicates with the third oil passing hole 103, the second oil passing hole 102 forming a second oil port on the left side surface of the oil block 1.

Thus, the hydraulic oil in the first oil passing hole 101 enters the third oil passing hole 103, the third oil passing hole 103 is communicated with the second oil passing hole 102, and a sealing plug in a third oil port of the third oil passing hole 103 seals the third oil passing hole 103, so that the hydraulic oil in the third oil passing hole 103 can only enter the second oil passing hole 102.

It should be noted that the second oil passing hole 102 and the third oil passing hole 103 may not be perpendicular, for example, the first oil passing hole 101 may be slightly inclined in the horizontal plane of the oil block 1, and the third oil passing hole 103 may be perpendicular to the first oil passing hole 101, but the second oil passing hole 102 and the third oil passing hole 103 may form an included angle of 85 ° -90 °.

Preferably, as shown in fig. 1, the oil passages are 5, the 5 oil passages are not communicated with each other, the hydraulic functional network comprises 5 hydraulic main pipes and 5 hydraulic branch pipes, each hydraulic main pipe is divided into a first pipe body and a second pipe body, the 5 first pipe bodies are respectively connected with one first oil port of the 5 first oil passing holes 101, and the 5 second pipe bodies are respectively connected with the other first oil port of the 5 first oil passing holes 101. The 5 hydraulic branch pipes are connected to the 5 second oil passing holes 102, respectively.

And 5 hydraulic main pipes are used for providing power for one lifting oil cylinder, and 5 hydraulic branch pipes are used for providing power for the other lifting oil cylinder.

Preferably, as shown in fig. 2, the first oil passing hole 101 must be lower than the second oil passing hole 102, and if the first oil passing hole 101 and the second oil passing hole 102 are disposed at the same height, the first oil passing hole 101 and the second oil passing hole 102 between the plurality of oil passages may cross, so that the plurality of oil passages are communicated.

Preferably, as shown in fig. 1 and 4, the heights of the 5 first oil passing holes 101 on the oil block 1 are the same, and the axes of the 5 first oil passing holes 101 are on the same horizontal plane. Since the heights of the 5 first oil passing holes 101 are the same and the third oil passing holes 103 extend from the top surface of the oil block 1 into the first oil passing holes 101, the depths of the 5 third oil passing holes 103 are the same.

Further, as shown in fig. 4, 5 third oil passing holes 103 are provided in order along the diagonal line of the top surface of the oil passage block 1. Since the distances from the 5 third oil passing holes 103 to the left side surface of the oil passage block 1 are different, the depths of the 5 second oil passing holes 102 are made different.

Specifically, the further the distance between the third oil passage hole 103 and the left side surface of the oil block 1, the deeper the depth of the second oil passage hole 102 communicating with the third oil passage hole 103. The closer the distance between the third oil passing hole 103 and the left side surface of the oil passage block 1, the shallower the depth of the second oil passing hole 102 communicating with the third oil passing hole 103. I.e., from the back surface of the oil block 1 to the front surface of the oil block 1, the depth of the 5 second oil passage holes 102 on the left side surface of the oil block 1 gradually decreases.

It should be noted that, since the pipe diameters of the 5 hydraulic main pipes are not all the same, the pipe diameters of the 5 hydraulic branch pipes are not all the same. Accordingly, the diameters of the first oil passing holes 101 in the different oil passing paths may be different, the diameters of the second oil passing holes 102 in the different oil passing paths may be different, and the diameters of the third oil passing holes 103 in the different oil passing paths may be different. The specific requirement is determined according to the pipe diameters of the actual hydraulic main pipe and the actual hydraulic branch pipe.

As a preferred embodiment, the connection modes between the main hydraulic pipe, the branch hydraulic pipe and the oil path block 1 are divided into flange connection and pipe joint connection. As shown in fig. 1, two of the five hydraulic main pipes are connected with the first oil passing hole 101 by a flange, and the remaining three hydraulic main pipes are connected with the first oil passing hole 101 by a pipe joint. Two of the five hydraulic branch pipes are connected with the second oil passing hole 102 in a flange manner, and the remaining three hydraulic branch pipes are connected with the second oil passing hole 102 in a pipe joint manner.

For example, pipe joint mounting threads are formed on the inner walls of the three first oil ports on the front surface of the oil block 1, and pipe joint mounting threads are also formed on the inner walls of the three first oil ports on the back surface of the oil block 1. The end parts of the three first pipe bodies are provided with external threads, so that three stainless steel heavy-duty pipes can be screwed on the end parts of the three first pipe bodies, and then pipe joints on the three first pipe bodies are sequentially screwed into three first oil ports with pipe joint mounting threads, which are arranged on the front surface of the oil path block 1. The three second pipe bodies can be installed in the corresponding three first oil ports according to the steps.

In addition, on the front surface of the oil path block 1, four first flange fixing screw holes 104 are formed at each first oil port requiring flange connection. Specifically, SAE split type split flanges are adopted for connection.

Optionally, the second oil port of the second oil passing hole 102 on the left side surface of the oil path block 1 can be connected with the hydraulic branch pipe by adopting a pipe joint connection mode, and can also be connected by using an SAE split type split flange.

If the hydraulic branch pipe is connected by adopting a pipe joint connection mode, pipe joint mounting threads are required to be arranged in the second oil port, and if the SAE split type split flange is used for connection, a second flange fixing screw hole 105 is required to be arranged beside the second oil port.

As shown in fig. 3 and 5, a counter bore 106 is formed at a third oil port at the top of the oil path block 1, the diameter of the counter bore 106 is slightly larger than that of the third oil passing hole 103, a rubber sealing ring is installed in the counter bore 106, the sealing plug is a bolt plug, and an internal thread matched with the bolt plug is arranged on the inner wall of the third oil port, so that when the bolt plug is installed, the sealing ring can be bonded into the counter bore 106 in advance, then the bolt plug is screwed into the third oil passing hole 103, and the lower surface of the bolt plug head presses the sealing ring into the counter bore 106 along with the fact that the bolt plug stretches into the third oil port. This improves the sealing effect, and the hydraulic oil in the third oil passage hole 103 is less likely to leak.

Optionally, as shown in fig. 6, a plurality of embedded parts 107 are arranged on the top surface of the oil path block 1, and each embedded part 107 is welded with a lifting lug. Specifically, two opposite corners of the top surface of the oil path block 1 are respectively provided with an embedded part 107, and each embedded part 107 is welded with a lifting lug. Because the oil block 1 is relatively heavy, lifting equipment is needed for transferring the oil block 1, and the oil block 1 is conveniently lifted by the two lifting lugs.

As shown in fig. 8, the hydraulic pipe channel pipe network joint assembly further comprises an oil collecting disc 2, the oil collecting disc 2 is placed in a pipe channel, a groove 201 is formed in the upper surface of the oil collecting disc 2, the groove 201 is used for collecting hydraulic oil, the hydraulic oil is prevented from directly dripping into the pipe channel, two channel steels 202 are installed in the groove 201, two ends of each channel steel 202 are respectively provided with a mounting hole 203, and four corners of the bottom of each oil channel block 1 are respectively provided with a threaded hole, so that the oil channel blocks 1 can be mounted on the channel steels 202 by using bolts.

Thus, when the hydraulic main pipe and the oil block 1 are disassembled, or when the hydraulic branch pipe and the oil block 1 are disassembled, the hydraulic oil in the oil block 1 is not directly dripped into the pipe groove, but is dripped into the groove 201 of the oil collecting disc 2. Therefore, the hydraulic oil in the pipe ditch is not required to be cleaned, and the pipe ditch is more environment-friendly.

Optionally, an oil outlet is formed in the bottom of the oil collecting disc 2, and a sealing plug is plugged into the oil outlet. Thus, the sealing plug is pulled out, and the hydraulic oil collected by the groove 201 can be discharged from the oil outlet, so that the use is more convenient.
