[0054] Embodiment 1:

[0055] like Figures 1 to 16As shown, a hydraulic linkage grouting machine adopts hydraulic drive to perform grouting operation, can use a piston rod to drive the movable components in the grouting cylinder and the hydraulic cylinder, and is designed so that the piston rod can run outside the two cylinder bodies, thereby effectively increasing the stroke of the piston assembly to facilitate pressure regulation, and a protection cylinder for maintaining the piston rod is arranged on one side of the grouting cylinder, which can effectively increase the service life of the entire grouting machine, and two inlet and outlet devices can be detachably matched thereon, so that it can realize double-station or double-slurry simultaneous operation in specific applications, thereby effectively reducing the purpose of equipment cost investment, including an oil tank 44, a motor 45, a radiator 46, an electronic valve 47, an electric control box 48 and a grouting device 49, the grouting equipment 49 includes a power cylinder and an inlet and outlet device detachably connected to the power cylinder, the power cylinder includes a protection cylinder, a grouting cylinder and a hydraulic cylinder connected to each other, a piston assembly 28 is arranged in the grouting cylinder and the hydraulic cylinder, and the piston assembly 28 includes a piston penetrating the grouting cylinder and the hydraulic cylinder The piston rod 22 is sleeved with a primary piston 24 and a secondary cylinder guide sleeve 23. The primary piston 24 seals the connection between the grouting cylinder and the hydraulic cylinder. The secondary cylinder guide sleeve 23 is provided with two groups, and the two groups of secondary cylinder guide sleeves 23 are respectively placed in the grouting cylinder and the hydraulic cylinder. Two groups of interfaces are respectively provided on the protection cylinder, the hydraulic cylinder and the grouting cylinder. Both ends of the piston rod 22 are placed outside the grouting cylinder and the hydraulic cylinder, and the piston rod 22 outside the grouting cylinder is placed in the protection cylinder. The inlet and outlet equipment includes a connection for connecting the grouting cylinder and the hydraulic cylinder. The tee 5 of the cylinder interface and the inlet and outlet parts connected to the two ends of the tee 5, the inlet and outlet parts of any inlet and outlet equipment are alternately connected or cut off under stress; the oil tank 44 is connected to the motor 45 through the oil supply pipeline, the motor 45 is respectively connected to the radiator 46 and the electronic valve 47 through the oil supply pipeline, the radiator 46 is respectively connected to an interface of the hydraulic cylinder and the protection cylinder through the oil supply pipeline, the other interfaces of the protection cylinder and the hydraulic cylinder are connected to the oil tank 44 through the oil supply pipeline, and the electronic valve 47 controls the connection of the oil tank 44.

[0056] As a preferred arrangement, the hydraulic grouting machine is provided with an oil tank 44, a motor 45, a radiator 46, an electronic valve 47, an electric control box 48 and a grouting device 49, wherein the oil tank 44 is used for oil supply, and the hydraulic oil in the oil tank 44 is pumped into the radiator 46 under the power of the motor 45;

[0057] The radiator 46 is used to cool the pumped oil and deliver the cooled oil to the hydraulic cylinder or the protection cylinder. The radiator 46 can prevent the operation of the entire oil supply system from being affected by excessive oil temperature, thereby avoiding the occurrence of power discontinuity failures.

[0058] The electronic valve 47 is connected to the oil supply pipeline on the output side of the motor 45 and the oil supply pipeline on the output side of the radiator through two oil supply pipelines, and is used to monitor the oil pressure in the oil supply pipeline on the output side of the motor and the oil supply pipeline on the output side of the radiator. When the monitoring value is higher or lower than the preset threshold, the oil supply amount of the pipeline connected to the motor in the oil tank 44 will be adjusted, so that the entire oil supply system is in a stable state, so as to stabilize the output of the hydraulic cylinder.

[0059] The hydraulic cylinder of the grouting equipment 49, under the action of the hydraulic oil provided by the radiator 46, makes the internal movable parts reciprocate, thereby driving the movable parts in the grouting cylinder connected thereto to reciprocate, thereby ensuring that the slurry (liquid) in the inlet and outlet devices connected on the two interfaces flows from the inlet side to the outlet side under pressure;

[0060] The electric control box 48 controls the connection of the radiator 46, the electronic valve 47 and the motor 45 respectively;

[0061] The grouting equipment 49 includes a power cylinder and an inlet and outlet device detachably connected to the power cylinder, the inlet and outlet device is used to connect the slurry inlet pipe (inlet pipeline) and the slurry outlet pipe (outlet pipeline), and the power cylinder uses hydraulic power to pressurize the slurry (or liquid) flowing through the inlet and outlet devices.

[0062] The power cylinder includes three parts: a protection cylinder, a grouting cylinder and a hydraulic cylinder which are connected to each other. A piston assembly 28 is arranged in the grouting cylinder and the hydraulic cylinder. The movable unit of the piston assembly 28 can reciprocate axially in the grouting cylinder and the hydraulic cylinder under the action of hydraulic power.

[0063] The piston assembly 28 is provided with a piston rod 22, on which a secondary cylinder guide sleeve 23, a primary piston 24 and a secondary cylinder guide sleeve 23 are sequentially sleeved. The piston rod 22 passes through the grouting cylinder and the hydraulic cylinder. The primary piston is placed at the connection between the grouting cylinder and the hydraulic cylinder to seal the connection between the grouting cylinder and the hydraulic cylinder and also acts as a bearing. Two groups of secondary cylinder guide sleeves 23 are respectively placed in the hydraulic cylinder and the grouting cylinder. Two groups of interfaces are respectively arranged on the protective cylinder, the hydraulic cylinder and the grouting cylinder. The interface on the hydraulic cylinder side is used to connect the hydraulic pipeline (oil supply pipeline) so as to input and output hydraulic oil in the hydraulic cylinder, and the hydraulic cylinder is used to provide power to the piston assembly in the hydraulic cylinder. The interface on the grouting cylinder is used to connect the import and export equipment, and the slurry inlet pipe and the slurry outlet pipe are connected through the import and export equipment to realize the transportation of grouting materials, so that two slurries or two workstations can be operated simultaneously.

[0064] Among them, both ends of the piston rod 22 are placed outside the grouting cylinder and the hydraulic cylinder, thereby providing a longer stroke for the piston assembly and making the pressure adjustment range more delicate. A protection cylinder is also connected to the far hydraulic cylinder connection end of the grouting cylinder. The piston rod 22 outside the grouting cylinder is placed in the protection cylinder, so that this section of the piston rod 22 is protected by the protection cylinder, which can increase the effective service life. When setting up, the protection cylinder can also be provided with a group of interfaces connected to the inside of the protection cylinder. When the piston rod 22 runs into the protection cylinder, it can be maintained by the material in the protection cylinder, thereby increasing the effective service life of the piston rod 22 on this side.

[0065] Any inlet and outlet equipment is mainly composed of three parts: a tee 5, an inlet part and an outlet part. The two ends of the tee 5 are respectively connected to the inlet part and the outlet part. The last interface of the tee 5 is connected to the interface of the grouting cylinder. In actual application, the grouting cylinder body of the existing hydraulic high-pressure grouting machine can be replaced with the power cylinder, so that its inlet and outlet oil pipes (oil inlet pipe and oil outlet pipe) are connected to the interface on the hydraulic cylinder side of the power cylinder, and the slurry inlet pipe and slurry outlet pipe for conveying slurry are respectively connected to the inlet part and the outlet part. When the hydraulic cylinder starts to move, for example, when the hydraulic oil in the hydraulic cylinder pushes the secondary cylinder guide sleeve 23 in the hydraulic cylinder to move toward the grouting cylinder side, the secondary cylinder guide sleeve 23 on the hydraulic cylinder side drives the piston rod 22. Since the piston rod 22 is located on the grouting cylinder side, it is also A secondary cylinder guide sleeve 23 is provided, and the secondary cylinder guide sleeve 23 on the grouting cylinder side moves toward the far hydraulic cylinder side. At this time, the inlet and outlet components on the far hydraulic cylinder side of the grouting cylinder are pressurized; conversely, when the hydraulic cylinder in the hydraulic cylinder pushes the secondary cylinder guide sleeve 23 in the hydraulic cylinder to move toward the far grouting cylinder side, the secondary cylinder guide sleeve 23 on the hydraulic cylinder side drives the piston rod 22. Since the piston rod 22 is located on the grouting cylinder side and a secondary cylinder guide sleeve 23 is also provided, the secondary cylinder guide sleeve 23 on the grouting cylinder side moves toward the near hydraulic cylinder side. At this time, the inlet and outlet components on the near hydraulic cylinder side of the grouting cylinder are pressurized; when the piston rod 22 runs into the protection cylinder, it can collect the material in the protection cylinder for maintenance, thereby increasing the effective service life of the piston rod 22 on this side.

[0066] When one inlet and outlet device of the grouting cylinder is pressurized during use, its inlet side is opened (the outlet side is closed), and the inlet and outlet side of the corresponding other inlet and outlet device is closed (the outlet side is opened), and vice versa.

Figures 1 to 16 As shown, in order to better realize the present invention, the following setting structure is particularly adopted: it also includes a hydraulic press frame for setting the oil tank 44 and the radiator 46, and the hydraulic press frame includes a base plate 51 for setting the oil tank 44 and the radiator 46, and handrails 50 and casters 52 are also arranged on the base plate 51. Preferably, the casters 52 are arranged on the opposite side of the base plate 51 where the oil tank 44 and the radiator 46 are arranged, and the handrail 50 is arranged at one end of the base plate 51 and is arranged near the end where the oil tank 44 is arranged.

[0075] As a preferred arrangement, a hydraulic press frame is provided for fixing the oil tank 44 and the radiator 46. The hydraulic press frame is an L-shaped structure consisting of a base plate 51 and an armrest 50. The oil tank 44 and the radiator 46 are both arranged on the base plate 51 of the L-shaped structure. Casters 52 are provided on the base plate 51 opposite to the surface where the oil tank 44 and the radiator 46 are arranged, and the armrest 50 is provided on the end surface adjacent to the oil tank 44.

[0076] However, when the motor 45 is installed in a horizontal installation manner, the handrail 50 is preferably arranged on the side of the electric control box 48 .

[0077] As a preferred setting scheme, a hose-type oil supply pipeline is connected between the motor 45 and the oil tank 44, a hard tube-type or hose-type oil supply pipeline is connected between the motor 45 and the radiator 46, a hard tube-type or hose-type oil supply pipeline is connected between the output side of the radiator 46 and the electronic valve 47, and between the output side of the motor 45 and the electronic valve 47.

[0078] When in use, the electric control box 48 controls the operation of the motor 45, and the motor 45 pumps the hydraulic oil in the oil tank 44 into the radiator 46. The radiator 46 cools the hydraulic oil and then transports it to one end of the hydraulic cylinder, and under the pressure of the hydraulic oil, pushes the piston assembly in the power cylinder to perform reciprocating motion in the power cylinder. Another oil supply pipeline of the hydraulic cylinder outputs the hydraulic oil in the hydraulic cylinder to the oil tank 44. The hydraulic oil cooled by the radiator 46 will also be transported to the protection cylinder through an oil supply pipeline. The piston rod 22 on the grouting cylinder side will be lubricated and protected in the protection cylinder, and the hydraulic oil in the protection cylinder will be returned to the oil tank 44 through another oil supply pipeline.

[0079] During operation, the hydraulic oil on the output layer side of the radiator 46 and the hydraulic oil on the output side of the motor 45 are output to the electronic valve for pressure monitoring. When the pressure value is abnormal (too high or too low or an unnecessary value, etc.), the oil supply into the pipeline on the input side of the motor 45 is adjusted in time (for example, when it is too high, the oil supply into the pipeline on the input side of the motor 45 is reduced; when it is too low, the oil supply into the pipeline on the input side of the motor 45 is increased, etc.).

[0107] Embodiment 12:

[0108] This embodiment is further optimized on the basis of any of the above embodiments, and the same parts as the above technical solutions will not be repeated here. Figures 1 to 16 As shown, in order to better implement the present invention, the following configuration structure is particularly adopted:

[0109] The inlet part includes a flat square valve sleeve 2 and a valve core assembly arranged in the flat square valve sleeve 2, and the inlet joint 1 and the three-way interface 3 are respectively connected at both ends of the flat square valve sleeve 2; the outlet part includes a flat square valve sleeve 2 and a valve core assembly arranged in the flat square valve sleeve 2, and the outlet joint 6 and the three-way interface 3 are respectively connected at both ends of the flat square valve sleeve 2; the interior of the flat square valve sleeve 2 is partitioned into a valve core assembly installation side and a non-valve core assembly installation side by a chassis 22, the non-valve core assembly installation side of the inlet part is connected to the tee 5 through the three-way interface 3, and the valve core assembly installation side of the outlet part is connected to the tee 5 through the three-way interface 3.

[0110] As a preferred setting scheme, the inlet part is mainly composed of an inlet joint 1, a flat square valve sleeve 2, a valve core assembly and a three-way interface 3. The interior of the flat square valve sleeve 2 is divided into a valve core assembly installation side and a non-valve core assembly installation side by a chassis 22. The inlet joint 1 is connected to the valve core assembly installation side of the flat square valve sleeve 2. The inlet joint 1 and the valve core assembly installation side of the flat square valve sleeve 2 constitute an activity space for the valve core assembly. The valve core assembly can be installed in the activity space and reciprocate in the activity space under the action of force. The non-valve core assembly installation side of the flat square valve sleeve 2 is connected to the three-way 5 through the three-way interface 3;

[0111] The outlet component is mainly composed of an outlet connector 6, a flat square valve sleeve 2, a valve core assembly and a three-way interface 3, wherein the outlet connector 6 and the three-way interface 3 are respectively connected to the two ends of the flat square valve sleeve 2, and the interior of the flat square valve sleeve 2 of the outlet component is partitioned into a valve core assembly installation side and a non-valve core assembly installation side by a chassis 22, and the outlet connector 6 is connected to the non-valve core assembly installation side of the flat square valve sleeve 2, and the three-way interface 3 and the valve core assembly installation side of the flat square valve sleeve 2 constitute an activity space for the valve core assembly, and the valve core assembly can be installed in the activity space and make reciprocating motion in the activity space under the action of force, and the valve core assembly installation side of the flat square valve sleeve 2 is connected to the three-way 5 through the three-way interface 3.

[0112] When in use, the inlet joint 1 of the inlet part can be connected to the slurry inlet pipe, and the outlet joint 6 can be connected to the slurry outlet pipe. Under the action of high pressure (the interface of the hydraulic cylinder provides pressure through the last channel of the tee 5), the valve core assembly will reciprocate in the installation side of the valve core assembly with the flat square valve sleeve 2. At the beginning, since the valve core assemblies are all pressed against the same side, assuming that the movement of the valve core assembly on the inlet part side is taken as the reference, when the valve core assembly on the inlet part side moves in the direction of the tee, the valve core assembly on the outlet part side does not move. At this time, the slurry in the slurry inlet pipe enters the inlet part, and the slurry on the inlet part side will pass through the space formed by the valve core assembly and the flat square valve sleeve 2 through the tee 5 to the outlet. The valve core assembly on the inlet piece side will move in the opposite direction under its own action, blocking the inlet on the inlet piece side. At this time, the valve core assembly on the outlet piece side will move toward the outlet joint 6 side under the action of pressure, and the valve core assembly on the outlet piece side will form a flow channel with the flat square valve sleeve 2. The slurry on the inlet piece side will be pressurized and flow out of the outlet piece through the flow channel and flow into the outlet pipe connected to the outlet piece. Then the pressure reverses again. At this time, the channel on the inlet piece side is opened, and the valve core assembly on the outlet piece side will be reset due to its own setting and block the outlet piece side. This process is repeated to achieve the purpose of slurry inlet and outlet.

The valve core assembly reciprocates in the space on the installation side of the valve core assembly with the flat square valve sleeve 2 under the action of force.

[0115] As a preferred setting scheme, the flat square valve sleeve 2 serves as the main body forming the activity space, and its interior is divided into two parts (referred to as the valve core assembly installation side and the non-valve core assembly installation side) by a formed chassis 11. The interior of the flat square valve sleeve 2 on the valve core assembly installation side is thickened toward the center of the flat square valve sleeve 2 to form an inner ring layer 12. The height (also called depth) of the inner ring layer 12 is lower than the overall height of the valve core assembly installation side. A center hole 9 and a slurry hole 10 are provided on the chassis 11 along the thickness direction of the chassis 11 (i.e., the axial direction of the flat square valve sleeve 2). Preferably, the slurry hole 10 is evenly arranged on the outside of the center hole 9, and the slurry hole 10 is penetrated on the valve core assembly side along the axial direction of the inner ring layer 12 (i.e., a through groove (slurry hole wall 13) is formed in the height direction of the inner ring layer 12).

At this time, the pressurized slurry will flow through the gap between the outer diameter of the large cylinder of the valve core on the outlet part side and the inner wall 14 of the inner ring layer and through the slurry hole 11 to the non-valve core component setting side with the flat square valve sleeve and further enter the outlet pipe connected to the outlet part; then the pressure is reversed again, at this time the valve core 42 on the inlet part side compresses the valve core spring 43, the channel on the inlet part side is opened, the slurry enters, and the valve core 42 on the outlet part side is affected by the rebound force of the valve core spring 43 to block the channel on the outlet part side. This is repeated to achieve the purpose of slurry inlet and outlet.

[0139] Embodiment 21:

[0140] This embodiment is further optimized based on any of the above embodiments. Figures 1 to 16 As shown, the same parts as the above-mentioned technical scheme will not be repeated here. When in use, the grouting cylinder body of the existing hydraulic high-pressure grouting machine can be replaced with the hydraulic grouting equipment, so that its oil inlet pipe (or oil outlet pipe) and oil outlet pipe (or oil inlet pipe) are connected to the C port 36 and D port 37 of the hydraulic cylinder, and the import and export equipment for conveying slurry is connected to the A port 30 and B port 32 of the grouting cylinder. When in use, an oil supply pipeline can be led out from the radiator 46 and the oil tank 44 respectively, and the two oil supply pipelines are respectively connected to the E port (or F port 40) 39 and the F port (or E port 39) 40, so as to provide hydraulic oil for protecting the cylinder. When the piston rod on the grouting cylinder side leaves the grouting cylinder and enters the three-stage cylinder barrel 38, the piston rod 22 can be lubricated by hydraulic oil for maintenance; when the hydraulic cylinder starts to move For example, when the hydraulic cylinder in the hydraulic cylinder pushes the secondary cylinder guide sleeve 23 in the hydraulic cylinder to move toward the grouting cylinder side, the secondary cylinder guide sleeve 23 on the hydraulic cylinder side drives the piston rod 22. Since the piston rod 22 is located on the grouting cylinder side and a secondary cylinder guide sleeve 23 is also provided, the secondary cylinder guide sleeve 23 on the grouting cylinder side moves toward the far hydraulic cylinder side. At this time, the inlet and outlet equipment on the A port 30 on the grouting cylinder is pressurized; conversely, when the hydraulic cylinder in the hydraulic cylinder pushes the secondary cylinder guide sleeve 23 in the hydraulic cylinder to move toward the far grouting cylinder side, the secondary cylinder guide sleeve 23 on the hydraulic cylinder side drives the piston rod 22. Since the piston rod 22 is located on the grouting cylinder side and a secondary cylinder guide sleeve 23 is also provided, the secondary cylinder guide sleeve 23 on the grouting cylinder side moves toward the near hydraulic cylinder side. At this time, the inlet and outlet equipment on the B port 32 on the grouting cylinder is pressurized.

[0141] When the A port 30 (or B port 32) of the grouting cylinder is pressurized during use, the inlet side of the inlet and outlet equipment connected thereto is opened (the outlet side is closed), and the inlet side of the inlet and outlet equipment connected to the corresponding B port 32 (or A port 30) is closed (the outlet side is opened), and vice versa.

[0142] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention is within the protection scope of the present invention.
