Description

Technical Field

[0001] The utility model relates to the technical field of monkey conveyors, in particular to a safety brake protection device for monkey conveyors. Background Art

[0002] A monkey conveyor, also known as an overhead passenger device, is an important part of the coal mine transportation chain, mainly used for auxiliary transportation of workers in underground mines. Its purpose is to shorten the travel time of miners going up and down the well, reduce the physical energy consumption of miners going up and down the well. Through the way of an overhead passenger cableway, miners can safely and quickly complete the journey of going up and down the well.

[0003] The starting mode of the monkey conveyor underground is to first open the safety brake, then open the working brake, and finally the main motor starts the monkey conveyor to run.

[0004] Currently, the existing safety brake protection device for monkey conveyors uses a travel switch. When the electro-hydraulic pusher works, an "L"-shaped hook on the robotic arm hooks the travel switch, making the normally open point of the travel switch become a normally closed point. Thus, the PLC will start the working brake only after detecting that the safety brake is opened. During the operation of the monkey conveyor, the "L"-shaped hook will come into rigid contact with the travel switch and cause damage, or fall off due to vibration, reducing the safety and stability of the system and causing the monkey conveyor to stop running. Content of the Utility Model

[0005] The purpose of the utility model is to provide a safety brake protection device for a monkey conveyor to solve the problems in the prior art that the travel switch is damaged due to rigid contact, or falls off due to vibration, reducing the safety and stability of the system and causing the monkey conveyor to stop running.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] The safety brake protection device for a monkey conveyor includes:

[0008] A fixing frame, one side of the fixing frame is fixedly provided with a connecting seat, and one side of the connecting seat is rotatably provided with a robotic arm;

[0009] An L-shaped bracket, a first strip hole is opened on one side of the corner of the L-shaped bracket, and a second strip hole is opened on one side of the L-shaped bracket;

[0010] An installation component is arranged on the fixing frame and the robotic arm and is used for installing the L-shaped bracket.

[0011] In a possible design, the installation component includes a base fixedly arranged on one side of the fixing frame, a bolt fixedly arranged at the center on one side of the base, a proximity switch fixedly arranged on one side of the robotic arm, a first nut is threadedly connected to the outside of the bolt, and a second nut is threadedly connected to the outside of the proximity switch.

[0012] In a possible design, the L-shaped bracket is sleeved and installed outside the proximity switch through the first strip-shaped hole and is locked and fixed by the second nut. The L-shaped bracket is sleeved and installed outside the bolt through the second strip-shaped hole and is position-limited by the first nut.

[0013] In a possible design, an electric telescopic rod is fixedly arranged at the bottom of the fixing frame. The same third rotating rod is rotatably arranged on both sides of the lower part of the robotic arm. The output end of the electric telescopic rod is fixedly connected to the third rotating rod.

[0014] In a possible design, the same first rotating rod is rotatably arranged on both sides of the upper part of the robotic arm. A buffer is fixedly arranged on one side of the first rotating rod. The second rotating rod is rotatably arranged at the tail end of the top of the fixing frame. The other end of the buffer is fixedly connected to the second rotating rod.

[0015] In a possible design, four mounting holes are formed in a rectangular shape on one side of the base.

[0016] In this application, when starting to use, first install the base and the bolt on it on one side of the fixing frame through the four mounting holes on the base. Then install the proximity switch on the robotic arm. Then remove the first nut and the second nut on the bolt and the proximity switch. Then take out the L-shaped bracket, sleeve the L-shaped bracket outside the proximity switch through its first strip-shaped hole, and install the second nut on the proximity switch to complete the preliminary locking. Then sleeve the L-shaped bracket outside the bolt through the second strip-shaped hole, and install the first nut on the bolt to limit the position of the L-shaped bracket, preventing the L-shaped bracket from falling off the bolt, making the installation of the L-shaped bracket more flexible and facilitating the adjustment of the distance between the trigger point and the proximity switch to meet the requirements under different working conditions. Then the whole man-riding belt conveyor is powered on and starts to work;

[0017] During the operation of the man-riding belt conveyor, since the travel switch in the original system is prone to failures due to damaged contacts or poor closing, the travel switch is replaced with a proximity switch and installed on one side of the robotic arm. The proximity switch detects through non-contact. When the "L"-shaped hook or other trigger components on the robotic arm approach, the normally open point of the proximity switch becomes a normally closed point, and sends a signal that the safety brake has been opened to the PLC. This method improves the accuracy and reliability of signal feedback, making the start-up process of the safety brake protection device of the man-riding belt conveyor more reliable. Even in the case where the safety brake is opened for a slightly longer time or the proximity switch closes slightly slower, the accurate detection of the proximity switch can ensure that the signal is timely fed back to the PLC, thus avoiding the problems that the man-riding belt conveyor cannot start or the brake fails;

[0018] The electric telescopic rod installed at the top of the fixing frame is connected to the robotic arm through the third rotating rod to achieve precise control of the robotic arm. The telescopic movement of the electric telescopic rod can quickly and accurately drive the robotic arm to move, thereby ensuring the rapid opening and closing of the safety brake. A buffer is fixed on the first rotating rod arranged above the robotic arm, and the other end is connected to the second rotating rod on the fixing frame. When the man-riding vehicle fails or undergoes emergency braking, the buffer can absorb the impact energy, reducing damage to mechanical components and safety risks to personnel.

[0019] The utility model has the following beneficial effects:

[0020] In the utility model, through the setting of the installation component, the flexible installation and convenient maintenance of the L-shaped bracket are realized, improving the overall reliability and service life of the device, and at the same time reducing the difficulty and cost of installation and maintenance;

[0021] In the utility model, through the setting of the L-shaped bracket, by adjusting the positions of the first strip hole and the second strip hole, the distance between the trigger point and the proximity switch can be flexibly adjusted to meet the requirements under different working conditions, thereby ensuring that the safety brake can accurately and timely respond to the control signal, improving the safety of the entire system;

[0022] Through the combination of the installation component and the L-shaped bracket in the utility model, precise control of the device is achieved, improving the accuracy and reliability of signal feedback, enhancing the safety and stability of the system, and ensuring the safe operation of the man-riding vehicle.
