Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable conductor racks, and in particular to a cable conductor rack with anti-jamming function. Background Technology
[0002] A cable tray is a device used to support, fix, and guide cable conductors. For example, when an elevator needs cable power to operate, the cable will move as the elevator car moves up and down to facilitate the operation of functions such as opening the elevator car door.
[0003] The cable may get stuck while moving with the elevator car, preventing it from continuing to move with the elevator car. In this case, it is necessary to stop the elevator car from moving to avoid the cable being pulled off due to the continuous movement of the elevator car. Utility Model Content
[0004] In view of this, the present invention provides a cable guide frame with anti-jamming function. The main technical problem to be solved is: when the cable is jammed and cannot move, the lifting and lowering of the elevator car can be stopped in time to avoid the cable being pulled off.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cable guide frame with anti-jamming function, comprising a fixing mechanism, a rotating mechanism installed inside the fixing mechanism, a connecting mechanism installed on the fixing mechanism, the fixing mechanism including a bracket, a limit switch fixedly connected inside the bracket, a disc movably connected to the left end of the limit switch, the connecting mechanism including a connecting frame installed outside the bracket, a connecting plate fixedly connected to the left end of the connecting frame, a connecting screw installed inside the connecting plate, the rotating mechanism including a rotating frame installed on the connecting screw, the right end of the rotating frame located inside the bracket, and the disc located inside the right end of the rotating frame.
[0006] By adopting the above technical solution, the fixing mechanism is installed on the elevator car during use. When the elevator car moves up and down, it will move up and down with the fixing mechanism. When the cable is stuck, the cable will stop moving. At this time, a downward pulling force will be generated at the fixing frame, causing the rotating frame to rotate around the connecting screw. The right end of the rotating frame will rotate upward, thereby pushing the disc upward, triggering the limit switch, cutting off the power to the elevator, and stopping the movement of the elevator car. This prevents the elevator car from continuing to move when the cable is stuck, which could cause the cable to break.
[0007] As a further description of the above technical solution:
[0008] A fixing plate is fixedly connected to the left end of the bracket.
[0009] By adopting the above technical solution, the fixed plate facilitates the installation of the bracket on the elevator car.
[0010] As a further description of the above technical solution:
[0011] The bottom of the support is movably connected to a movable column, the bottom of which is located below the support, and the top of which extends into the interior of the rotating frame.
[0012] By adopting the above technical solution, the rotating frame is connected to the support by a movable column, which makes it easy for the rotating frame to return to its original position after the cable is restored to its original position.
[0013] As a further description of the above technical solution:
[0014] A support plate is fixedly connected to the bottom of the movable column, and a spring is installed on the outer surface of the movable column. The top of the spring is in contact with the lower surface of the bracket, and the bottom of the spring is in contact with the upper surface of the support plate.
[0015] By adopting the above technical solution, when the cable is stuck, the right end of the rotating frame will rotate upward. At this time, the spring will be compressed and store some elastic potential energy. When the cable resumes movement, the spring loses resistance and releases elastic potential energy, so that the right end of the rotating frame can rotate downward and return to its original position. It will no longer push the disc upward, allowing the disc to also return to its original position. At this time, the limit switch sends a signal, and the elevator is powered again.
[0016] As a further description of the above technical solution:
[0017] The top of the movable column is threaded with a fixing nut, which is located inside the rotating frame.
[0018] By adopting the above technical solution, it is easy for the rotating frame to return to its original position.
[0019] As a further description of the above technical solution:
[0020] A fixed frame is fixedly connected to the left end of the rotating frame, and a cable is installed inside the fixed frame.
[0021] By adopting the above technical solution, the cable is fixed to the left end of the rotating frame using a fixing bracket.
[0022] By employing the above technical solution, the cable tray with anti-jamming function of this utility model has at least the following beneficial effects:
[0023] 1. Compared with the prior art, this cable guide frame with anti-jamming function, through a fixing mechanism, a rotating mechanism, and a connecting mechanism, moves the fixing mechanism up and down along with the elevator car when it moves up and down. When the cable is jammed, the cable will stop moving. At this time, a downward pulling force will be generated at the fixing frame, causing the rotating frame to rotate around the connecting screw. The right end of the rotating frame will rotate upward, thereby pushing the disc upward, triggering the limit switch, cutting off the power to the elevator, and stopping the movement of the elevator car. This prevents the elevator car from continuing to move when the cable is jammed, which could cause the cable to break.
[0024] 2. Compared with the existing technology, this cable guide frame with anti-jamming function will rotate upward when the cable is jammed. At this time, the spring will be compressed and store some elastic potential energy. When the cable resumes movement, the spring loses resistance and releases elastic potential energy, so that the right end of the rotating frame can rotate downward and return to its original position. It will no longer push the disc upward, and the disc can also return to its original position. At this time, the limit switch sends a signal and the elevator is powered again.

[0030] Reference Figure 1-3This utility model provides a cable guide frame with anti-jamming function, comprising a fixing mechanism 1, a rotating mechanism 2 installed inside the fixing mechanism 1, and a connecting mechanism 3 installed on the fixing mechanism 1. The fixing mechanism 1 includes a bracket 101, and a limit switch 103 is fixedly connected inside the bracket 101. The limit switch 103 can be a Schneider XCE-145. A disc 104 is movably connected to the left end of the limit switch 103. When the disc 104 is moved, the limit switch 103 will send an electrical signal to control the on / off of the elevator circuit. The connecting mechanism 3 includes a connecting frame 301, which is installed on the outside of the bracket 101. A connecting plate 302 is fixedly connected to the left end of the connecting frame 301, and a connecting screw 303 is installed inside the connecting plate 302. The rotating mechanism 2 includes a rotating frame 201, which is installed on the connecting screw 303. The right end of the rotating frame 201 is located on the bracket. Inside 101, the disc 104 is located inside the right end of the rotating frame 201. The left end of the rotating frame 201 is fixedly connected to the fixing frame 202. The fixing frame 202 contains a cable 203, which is fixed to the left end of the rotating frame 201. In use, the fixing mechanism 1 is installed on the elevator car. When the elevator car moves up and down, it will move up and down with the fixing mechanism 1. When the cable 203 is stuck, the cable 203 will stop moving. At this time, a downward pulling force will be generated at the fixing frame 202, causing the rotating frame 201 to rotate around the connecting screw 303. This causes the right end of the rotating frame 201 to rotate upward, thereby pushing the disc 104 upward and triggering the limit switch 103 to cut off the power to the elevator, thus stopping the movement of the elevator car and preventing the elevator car from continuing to move when the cable 203 is stuck, which could cause the cable 203 to break.
[0031] A fixing plate 102 is fixedly connected to the left end of the bracket 101, which facilitates the installation of the bracket 101 on the elevator car.
[0032] A movable column 105 is movably connected to the bottom of the bracket 101. The bottom of the movable column 105 is located below the bracket 101, and the top of the movable column 105 extends into the interior of the rotating frame 201. A support plate 106 is fixedly connected to the bottom of the movable column 105. A spring 107 is installed on the outer surface of the movable column 105. The top of the spring 107 is in contact with the lower surface of the bracket 101, and the bottom of the spring 107 is in contact with the upper surface of the support plate 106. A fixing nut 108 is threadedly connected to the top of the movable column 105 for fixing. Nut 108 is located inside rotating frame 201. When cable 203 is jammed, the right end of rotating frame 201 will rotate upward. At this time, spring 107 will be compressed and store some elastic potential energy. When cable 203 resumes movement, spring 107 loses resistance and releases elastic potential energy, allowing the right end of rotating frame 201 to rotate downward and return to its original position. It will no longer push disk 104 upward, allowing disk 104 to also return to its original position. At this time, limit switch 103 sends a signal, and the elevator is powered again.
[0033] Working principle: When in use, the fixing mechanism 1 is installed on the elevator car. When the elevator car moves up and down, it will move up and down with the fixing mechanism 1. When the cable 203 is stuck, the cable 203 will stop moving. At this time, a downward pulling force will be generated at the fixing frame 202, causing the rotating frame 201 to rotate around the connecting screw 303. The right end of the rotating frame 201 will rotate upward, thereby pushing the disc 104 upward, triggering the limit switch 103 to cut off the power to the elevator, thereby stopping the movement of the elevator car and preventing the elevator car from continuing to move when the cable 203 is stuck, which could cause the cable 203 to break.
