The mobile frame structure 2 is a load-bearing structure of a steel structure welded part or other materials similar to this structure, designed for the purpose of bearing weight. This structure is the main load-bearing structure of this device, spanning both sides of the gate rising slot. The wheel device 1 or a component with the same mobile functional structural device that can provide rolling friction is fastened together with both sides of the mobile frame structure 1 through bolt connection, so that the two wheel devices 1 or components with the same mobile functional structural device that can provide rolling friction can push the entire mobile frame structure 2 to move on a plane. The separate jack 3 is fixed on the middle crossbeam of the mobile frame structure 2, and two are arranged symmetrically about the center line of the gate slot. The push-out jack 4 is the main power source for pushing the entire locking device forward or backward. It is hinged to the mobile frame structure 2 through the hinged device bracket 6. The push-out jack support 5 is a support fixed on the surface of the embedded part, which is mainly used to fix the push-out jack 4 and provide support for its operation.

[0019] Furthermore, the mobile frame structure 2 is a welded steel structure. This structure is the main load-bearing structure of the device, spanning both sides of the door slot. This structure bears all the loads and transfers the loads.

[0020] Furthermore, the mobile frame structure 2 has two pieces, which are symmetrically arranged on both sides of the door slot;

[0021] Furthermore, the wheel device 1 supports the entire locking structure so that it can roll on the ground;

[0022] Furthermore, the separate jacks 3 are fixed to the middle crossbeam of the mobile frame structure 2, and two are arranged symmetrically with respect to the center line of the door slot. After being released from the connection with the hinged device bracket 6, the separate jacks 3 can start lifting;

[0023] Furthermore, the push-out jack 4 is the main power source for pushing the entire locking device forward or backward, and is hinged to the mobile frame structure 2 through the hinge device bracket 6;

[0024] Furthermore, the push-out jack support 5 is a support fixed on the surface of the embedded part, mainly used to fix the push-out jack 4 and provide support for its operation.

[0025] Example 1:

[0026] In the hydraulic metal structure flood control gate, the working gate needs to be opened and closed frequently, and the locking devices on both sides have always been pushed to the locking position manually. This method is inefficient and it is often difficult for two people to push the nearly 300kg locking device. For this reason, a locking device with four degrees of freedom with automatic pushing out, resetting, lifting and lowering is invented. The locking device consists of a mobile frame structure, a driving cylinder, a hydraulic jack, a hydraulic pump station, etc. The locking device is a welded structure made of Q355C; the lower part of the locking beam is provided with a traveling wheel, the jack is provided on the upper part of the locking beam, and the movable hydraulic oil pump station is placed on the upper locking platform. During operation, the locking beam is parked at the end of the locking platform. When the counterweight needs to be locked, the locking beam is pushed out by the hydraulic cylinder and placed under the hydraulic metal structure that needs to be locked:

[0027] The preferred solution is Figure 1-3As shown, a locking device with four degrees of freedom based on a hydraulic system, the entire structure is composed of a wheel device 1, a mobile frame structure 2, a separate jack 3, a push-out jack 4, a jack support 5, and an articulated device bracket 6. The mobile frame structure 2 is a load-bearing structure of a steel structure welded part or other materials similar to this structure, designed for the purpose of bearing weight. This structure is the main load-bearing structure of this device, spanning both sides of the gate rising slot. The wheel device 1 or a component with the same mobile functional structural device that can provide rolling friction is fastened together with both sides of the mobile frame structure 1 through bolt connection, so that the two wheel devices 1 or components with the same mobile functional structural device that can provide rolling friction can push the entire mobile frame structure 2 to move on a plane. The separate jack 3 is fixed on the middle crossbeam of the mobile frame structure 2, and two are arranged symmetrically about the center line of the gate slot. The push-out jack 4 is the main power source for pushing the entire locking device forward or backward. It is hinged to the mobile frame structure 2 through the hinged device bracket 6. The push-out jack support 5 is a support fixed on the surface of the embedded part, which is mainly used to fix the push-out jack 4 and provide support for its operation.

[0028] The working principle of this device:

[0029] like Figure 1-3 As shown in the figure, the locking device consists of a mobile frame structure, a drive cylinder, a hydraulic jack, and a hydraulic pump station. The locking device is a welded structure made of Q355C. Travel wheels are located at the bottom of the locking beam, the jack is located above the locking beam, and the movable hydraulic pump station is placed on the upper locking platform. During operation, the locking beam rests on the end of the locking platform. When the counterweight needs to be locked, the hydraulic cylinder pushes the locking beam out and places it below the hydraulic metal structure to be locked.
