Description

Technical Field

[0001] The utility model belongs to the technical field of electric power facilities, and specifically relates to a switch door lock actuator. Background Art

[0002] Switch cabinets need to be regularly inspected, maintained, replaced, repaired, and tested, which requires the cooperation of maintenance teams, protection teams, and test teams. There are many projects and many workers to cooperate with, which results in a large number of tools and instruments being carried for each pre-test. At the same time, there are trolley-type circuit breakers in the switch cabinet. Trolley-type circuit breakers are large in size and heavy in weight. During replacement, maintenance, and testing, operators need to operate close to the switch cabinet. The degree of automation is low, and it is time-consuming and labor-intensive. In addition, on-site operations require manual repeated replacement of maintenance tools and test instruments, and frequent wiring changes, which not only makes the on-site test wiring numerous and messy, but also poses a risk of electric shock due to inadequate test safety measures.

[0003] Currently, most maintenance robots are used to solve the above problems. The maintenance robots include an operating part for opening the cabinet door and a transporting part for transporting the circuit breaker. The operating part includes a robotic arm and a variety of maintenance tools that are compatible with the robotic arm, namely, a key-turning actuator for opening the cabinet door, a switch door lock actuator, a screw-turning actuator, and a switch door lock actuator for plugging in and out the relay. Existing switch door lock actuators generally include a switch quick-change fixture, a switch connection base plate connected to the switch quick-change fixture, a switch sleeve connected to the switch connection base plate, a main operating rod and an auxiliary operating rod slidably connected to the switch sleeve, a main spring and an auxiliary spring respectively cooperating with the main operating rod and the auxiliary operating rod, and a switch pressure sensor connected to the main operating rod. During operation, when the main operating rod contacts the surface of the switch cabinet, the switch pressure sensor is triggered to turn the switch. However, since the door of the switch cabinet is elastic, especially when closing the door, there will be an outward force to resist the door closing, so it is necessary to apply a closing pressure to it. However, the main operating rod of the existing switch door lock actuator only contacts the surface of the switch cabinet and cannot form a pressure on the switch cabinet door, thereby affecting the closing of the switch cabinet door lock.

[0027] In order to make the technical problems, technical solutions and beneficial effects to be solved by the utility model more clearly understood, the utility model is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not intended to limit the utility model.

[0028] Please also refer to Figures 1 to 4, the utility model switch door lock actuator is described. The switch door lock actuator includes a door lock device 10, a crimping device 20 and an exchange fixture 30; the door lock device 10 includes a driving unit 11 and a twisting unit 12 hinged thereto, the twisting unit 12 is provided with a clamping portion for fixing the switch door lock, and the driving unit 11 is used to drive the twisting unit 12 to rotate along a predetermined trajectory; the crimping device 20 is provided on one side of the driving unit 11, the crimping device 20 includes a pressure rod 21 hinged to the driving unit 11, the bottom of the pressure rod 21 is formed with an abutment portion, and the abutment portion abuts against the cabinet door of the switch cabinet during operation; the exchange fixture 30 is fixed to the top of the door lock device 10 and is used for rapid exchange with the robot's mechanical arm.

[0029] The utility model provides a switch door lock actuator. Compared with the prior art, the cabinet door of the switch cabinet can be better closed by setting a pressure rod 21. When closing the cabinet door, the actuator is first installed on the mechanical arm through the exchange clamp 30, and then the driving unit 11 drives the pressure rod 21, adjusts its angle so that it presses against the cabinet door, and then fixes the door lock of the cabinet door by twisting the clamping part of the unit 12. Then the driving unit 11 drives the clamping part to rotate along a predetermined trajectory, thereby locking the door; this setting makes it easier to lock the cabinet door and can avoid failure to lock the door due to resistance of the cabinet door.

[0030] Specifically, the door lock of the switch cabinet includes a switch handle and a lock hole. The door lock described in the utility model is a switch handle, one end of which is hinged on the cabinet door, and the other end can be rotated up and down along the hinged end. The rotation path is a predetermined trajectory. When opening the cabinet door, the switch handle is moved upward to open it, and when closing the cabinet door, the switch handle is moved downward to lock the door.

[0031] Specifically, when opening the cabinet door, after the key actuator is used to open the lock hole of the switch cabinet, the robotic arm quickly replaces the switch door lock actuator through the exchange fixture 30, and then the robotic arm drives the pressure rod 21 to press against the cabinet door. During this process, the drive unit 11 can drive the pressure rod 21 to adjust the pressing angle. Then, after the clamping part fixes the door lock, the drive unit 11 drives the clamping part to rotate upward, thereby driving the door lock to open. Finally, the robotic arm drives the actuator to move slowly, thereby slowly opening the cabinet door.

[0032] Specifically, the robotic arm is fixed to the operating part of the maintenance robot. The robotic arm can be extended and retracted and can move in the front, back, left and right directions. Therefore, after opening the cabinet door, the robotic arm can drive the actuator to move slowly away from the cabinet door. After the cabinet door is fully opened, the subsequent steps can be carried out.

[0033] In some embodiments, an improved embodiment of the above-mentioned door lock actuator can be adopted as follows Figure 1 、 Figure 2The structure shown. Figure 1 、 Figure 2 The pressing device 20 further includes a pressing wheel 22 rotatably connected to the bottom of the pressing rod 21, and the pressing wheel 22 forms the abutting portion. The pressing wheel 22 is rotatably connected to the bottom of the pressing rod 21. When in operation, the pressing wheel 22 abuts against the cabinet door, which can reduce friction between the cabinet door and the pressing wheel 22, thereby reducing damage to the cabinet door.

[0034] In some embodiments, an improved embodiment of the above-mentioned door lock actuator can be adopted as follows Figure 1 、 Figure 2 The structure shown.

By setting two adjustment blocks 1212 and setting a roller 1214 on each adjustment block 1212, the sliding movement is achieved through the cooperation between the roller 1214 and the slider 1215, thereby achieving the adjustment of the position of the clamp 122; an adjustment groove 1213 is set on each adjustment block 1212, and a driving member is set in the adjustment groove 1213, and rollers 1214 are set at the upper and lower ends of the driving member, which can cooperate with the upper and lower sides of the slider 1215 at the same time, thereby achieving consistency in the up and down movement of the slider 1215.

[0036] Optionally, the driving member can be a double-axle extension motor, with a rotating shaft extending from the upper and lower sides of the motor respectively. Each roller 1214 is fixedly connected to a rotating shaft, which can realize synchronous driving of the two rollers 1214 by the driving member, thereby realizing the linear movement of the slider 1215.
