The hydraulic oil in the rodless cavity 106 of the hydraulic cylinder 100 flows back to the external oil tank through the rodless cavity oil inlet and return passage 204 and the second oil port 206.
It should be understood that the above-described embodiment is only an exemplary embodiment of the present invention, and does not constitute any limitation to the present invention. That is, the hydraulic cylinder assembly is not only used in a roof bolt support system.
In one embodiment of the present invention, as shown in fig. 3, the rod chamber oil return passage 203 and the rodless chamber oil inlet and return passage 204 are communicated with each other. And a check valve 400 is further installed between the rod cavity oil return passage 203 and the rodless cavity oil inlet and return passage 204, so that hydraulic oil in the rod cavity oil return passage 203 can only flow into the rodless cavity oil inlet and return passage 204 in a single direction.
Further, in an embodiment of the present invention, the check valve 400 can be switched between a forward on state and a reverse off state.
The check valve 400 is in the forward conducting state based on the backflow of the oil inside the rod chamber 105. Oil in the rod cavity 105 can flow forward to the rodless cavity oil inlet and return passage 204 through the rod cavity oil return passage 203 and the check valve 400 to supply oil to the rodless cavity 106;
the check valve 400 is in the reverse blocking state based on the fact that the oil inside the rod chamber 105 does not flow back. The oil in the rodless chamber oil inlet and return passage 204 cannot flow downstream into the rod chamber oil return passage 203.
Specifically, as shown in fig. 1 to 6, the hydraulic cylinder assembly includes: hydraulic cylinder 100, mount 200, and tubing 300.
The hydraulic cylinder 100 includes a cylinder 101, a piston rod 102, a piston 103, and a guide sleeve 104. A guide sleeve 104 is installed at one end of the cylinder 101, and the piston rod 102 passes through the guide sleeve 104 and extends to the inside of the cylinder 101. A piston 103 is mounted on the piston rod 102 at an end remote from the guide sleeve 104.
The mount 200 is connected to the cylinder 101. The mount 200 is located at an end of the cylinder tube 100 remote from the guide sleeve 104. The mounting seat 200 is formed with a coupling boss 201.

Meanwhile, a first oil port 205 is provided at an outer end portion of the rod chamber oil feed passage 202. A second oil port 206 is arranged at the outer end part of the rodless cavity oil inlet and return passage 204. The first oil port 205 and the second oil port 206 are externally connected with an oil tank.
Wherein the oil pipe 300 is connected between the hydraulic cylinder 100 and the mount 200 such that the rod chamber 105 of the hydraulic cylinder 100 is in communication with the rod chamber oil inlet passage 202 and the rod chamber 105 is in communication with the rod chamber oil return passage 203. The rodless chamber inlet and return passages 204 communicate with the rodless chamber 106 of the hydraulic cylinder 100.
Meanwhile, the rod cavity oil return passage 203 and the rodless cavity oil inlet and return passage 204 are communicated with each other. And a check valve 400 is further installed between the rod cavity oil return passage 203 and the rodless cavity oil inlet and return passage 204, so that hydraulic oil in the rod cavity oil return passage 203 can flow forward into the rodless cavity oil inlet and return passage 204, and hydraulic oil in the rodless cavity oil inlet and return passage 204 cannot flow forward into the rod cavity oil return passage 203.
In a specific operation process, in an initial state, there is no hydraulic oil in the rod cavity 105, and the hydraulic oil in the external oil tank firstly flows into the rod-free cavity 106 of the hydraulic cylinder 100 through the second oil port 206 and the rod-free cavity oil inlet and return passage 204. The hydraulic oil in the rodless chamber 106 of the hydraulic cylinder 100 generates a thrust force on the piston 103, and the piston 103 drives the piston rod 102 to extend out of the cylinder 101 to support the anchor rod support. Subsequently, the hydraulic oil externally connected to the oil tank flows into the rod chamber 105 of the hydraulic cylinder 100 from the first oil port 205 through the rod chamber oil inlet passage 202 and the oil pipe 300 to drive the piston 103 to retract the piston rod 102 into the cylinder 101 of the hydraulic cylinder 100. The hydraulic oil in the rodless cavity 106 of the hydraulic cylinder 100 flows back to the external oil tank through the rodless cavity oil inlet and return passage 204 and the second oil port 206.
In the initial state of the next cycle, the rod chamber 105 is filled with hydraulic oil, and the hydraulic oil in the external oil tank first flows into the rod-less chamber 106 of the hydraulic cylinder 100 through the second oil port 206 and the rod-less chamber oil inlet and return passage 204. The hydraulic oil in the rodless chamber 106 of the hydraulic cylinder 100 generates a thrust force on the piston 103, and the piston 103 drives the piston rod 102 to extend out of the cylinder 101 to support the anchor rod support. At the same time, the hydraulic oil in the rod chamber 105 of the hydraulic cylinder 100 flows back to the check valve 400 through the oil pipe 300 and the rod chamber oil return passage 203 and opens the check valve 400 into the rod-less chamber oil inlet and return passage 204. Thereby, the hydraulic oil returned from the rod chamber 105 of the hydraulic cylinder 100 can participate in the supply of oil to the rodless chamber 106 of the hydraulic cylinder 100.
According to the above-described embodiment, the rod chamber oil return passage 203 and the rodless chamber oil inlet and return passage 204 are communicated with each other. And a check valve 400 is also installed between the rod chamber oil return passage 203 and the rodless chamber oil inlet and return passage 204. The hydraulic oil in the rod cavity 105 of the hydraulic cylinder 100 can flow back to the rodless cavity oil inlet and return channel 204 to supply oil to the rodless cavity 106 of the hydraulic cylinder 100, so that the oil filling speed of the rodless cavity 106 can be increased, the extension speed of the piston rod 102 is greatly increased, and the working efficiency is also improved.
