Description

Technical Field

[0001] The utility model relates to the field of metal doors, and particularly relates to an overweight door flipping device with high safety. Background Technique

[0002] Large steel doors usually weigh 200 - 400 kilograms, or even more. In the traditional processing method of steel doors, 6 - 8 workers are often required to cooperate with each other. During long - term labor, workers are prone to fatigue and inattention, which can easily cause safety accidents, and the production efficiency is also very low.

[0003] At present, a Chinese patent with the authorization announcement number CN218173748U discloses a door and window flipping device. A clamping component for clamping doors and windows is arranged in the middle of a spherical flipping frame. A sliding base is slidably connected to the bottom of the spherical flipping frame. A first rotating component for rotating the spherical flipping frame along its central horizontal axis is arranged on the sliding base. A fixed base is arranged below the sliding base. A second rotating component for rotating the sliding base along its central vertical line is arranged on the fixed base. A first limiting component for restricting the rotation of the sliding base is also arranged on the fixed base; a top plate is arranged on the top of the spherical flipping frame. The top plate is fixedly connected to the fixed base. A second limiting component for restricting the shaking of the spherical flipping frame is arranged on the top plate. This utility model is applied to flip and deflect doors and windows during door and window assembly, replacing manual labor, realizing mechanical flipping of workpieces, improving production efficiency while reducing the labor intensity of employees, and setting a directional output angle according to different production sites and production lines.

[0004] The above - mentioned existing technical solutions have the following defects: The doors and windows that this device can flip generally have a relatively light weight and cannot be applied to large steel doors, and the safety cannot be guaranteed. Moreover, if complete mechanical flipping replacing manual labor is to be achieved, the performance and strength requirements for the materials of the motor and the flipping frame are high, and the cost is relatively large. Content of the Utility Model

[0005] The purpose of this utility model is to provide an overweight door flipping device with high safety to solve the problems existing in the above - mentioned existing technology.

[0006] The above - mentioned technical purpose of this utility model is achieved through the following technical solutions:

[0007] An overweight door flipping device with high safety includes a support frame, a spring fixing device and a motor. The support frame includes a support frame body, support feet and a moving platform;

[0008] The support frame body is composed of a top cross - beam, a bottom cross - beam and a ball screw;

[0009] On one side of the bottom cross beam, a plurality of support feet are provided. On the other side of the bottom cross beam, a bottom platform is provided. At the center position of the top of the bottom platform, a motor is provided.

[0010] A first through hole is provided at the middle position of the bottom cross beam, and a second through hole is provided at the middle position of the top cross beam. A ball screw is coaxially arranged in the first through hole and the second through hole. A transmission mechanism is provided at the bottom end of the ball screw. The ball screw is in transmission connection with the motor through the transmission mechanism.

[0011] A moving platform is arranged on the ball screw. A second through hole is provided on the cross beam on the side of the moving platform away from the support body. A spring fixing device is arranged in the second through hole. A control terminal is arranged in the moving platform. The control terminal is electrically connected to the motor through an electric wire.

[0012] By adopting the above technical solution, the spring fixing device enables the user to ensure that the steel door is fixed so that it will not accidentally fall during the flipping process, causing unnecessary personal injuries. The ball screw and the motor on the support frame are both used to lift the steel door. During the lifting process, since the weight ratio on both sides of the positioning hole of the steel door cannot be kept consistent, it will naturally enter a hanging state. At this time, the lower side can be lifted manually. At this time, the motor rotates in reverse, driving the moving platform to descend. After the steel door contacts the installation table, it will enter a flat state again. Since a layer of soft material is laid on the installation table, there is no need to worry about the steel door being scratched during the contact with the installation table. This method is economical and convenient, and also greatly reduces the number of personnel required in the processing process.

[0013] In a further embodiment, a first infrared sensor and a second infrared sensor are respectively arranged on the left and right sides of the moving platform. A third infrared sensor is arranged at the top end of the ball screw. The first infrared sensor, the second infrared sensor and the third infrared sensor are electrically connected to the control terminal through electric wires. A power supply VCC is arranged at the bottom of the motor 3.

[0014] One end of the power supply VCC is connected to one end of a resistor R1. The other end of the resistor R1 is connected to one end of an infrared sensor IR1. The other end of the infrared sensor IR1 is grounded.

[0015] The power supply VCC is also connected to one end of a resistor R2. The other end of the resistor R2 is connected to one end of an infrared sensor IR2. The other end of the infrared sensor IR2 is connected to one end of a resistor R3. The other end of the resistor R3 is connected to one end of a capacitor C1. The other end of the capacitor C1 is connected to the power supply VCC. The other end of the infrared sensor IR1 is connected to the other end of the infrared sensor IR2.

[0016] The other end of the resistor R3 is connected to one end of the resistor R4, the other end of the resistor R4 is connected to one end of the infrared sensor IR3, the other end of the infrared sensor IR3 is connected to one end of the infrared sensor IR4, the other end of the infrared sensor IR4 is connected to one end of the resistor R5, the other end of the resistor R5 is connected to one end of the resistor R4, one end of the resistor R6 is connected to one end of the infrared sensor IR4, the other end of the resistor R6 is connected to one end of the normally open contact K1, the other end of the normally open contact K1 is connected to one end of the resistor R4, and one end of the normally open contact K1 is also connected to the other end of the resistor R3;

[0017] The other end of the normally open contact K1 is connected to one end of the resistor R7, the other end of the resistor R7 is connected to one end of the infrared sensor IR5, the other end of the infrared sensor IR5 is connected to the base of the triode Q1, the emitter of the triode Q1 is grounded, the collector of the triode Q1 is connected to one end of the resistor R8, and the other end of the resistor R8 is connected to one end of the resistor R7;

[0018] The other end of the infrared sensor IR5 is connected to the emitter of the triode Q1.

[0019] By adopting the above technical solution, it is possible to detect whether the door body is in a balanced or naturally hanging state through the infrared sensor. If the infrared sensors on both the left and right sides of the mobile platform detect an object, then the door body is in a balanced state. If only one side detects it, or if an object passes through a certain infrared sensor in a certain order, then the motor will operate under the control of the control terminal to raise or lower the mobile platform, so as to cooperate with the manual operation to complete the flipping. The triode Q1 is a photosensitive triode. As long as the light emitted by the infrared sensor IR5 irradiates on the base of the photosensitive triode, it can achieve an amplification effect and is more sensitive than an ordinary photosensitive diode. Since the third infrared sensor needs to detect the moment when the overweight door flips, the more sensitive triode Q1 needs to be used.

[0020] In a further embodiment, a plurality of grooves are provided on the support feet, a rotating shaft is horizontally arranged in the grooves, and rollers are sleeved on the rotating shaft.

[0021] By adopting the above technical solution, these rollers help the flipping device to move limitedly in the factory. After the movement is completed, corresponding fixing devices are also provided on the support feet, which can prevent accidents such as the steel door falling due to the displacement of the flipping device during operation.

[0022] In a further embodiment, the spring fixing device includes a device body, a first stopper, a second stopper and a fixing spring. The first stopper is fixedly connected to one end of the device body, the second stopper is fixedly connected to the other end of the device body, the fixing spring is sleeved on the device body, one end of the fixing spring is fixedly connected to one side of the cross beam, and the other end of the fixing spring is fixedly connected to the side of the second stopper close to the cross beam.

[0023] By adopting the above technical solution, the device body is a metal rod, which is arranged in the through hole in the middle of the cross beam of the moving platform. The first stopper and the second stopper are respectively arranged at the front and rear ends of the metal rod, which can limit the metal rod. The spring between the cross beam and the second stopper can cooperate with the first stopper to facilitate pulling up the spring fixing device and then inserting it into the positioning hole on the steel door, and the steel door is fixed by the spring to prevent the steel door from falling during the flipping process, effectively improving the safety.

[0024] In a further embodiment, an inclined chamfer is arranged at one end of the device body, and the inclined chamfer is used to assist the device body to enter the positioning hole on the door.

[0025] By adopting the above technical solution, the inclined chamfer arranged at one end of the device body that needs to be inserted into the positioning hole of the steel door can effectively improve the fixing efficiency. It is not necessary to align the device body and the steel door very accurately. As long as the relative accuracy is ensured, the fixing device can be inserted, effectively improving the production efficiency. At the same time, it also reduces the loss of the device body and improves the overall service life of the flipping device.

[0026] In a further embodiment, an emergency stop button is arranged on the top of the motor.

[0027] By adopting the above technical solution, the motor is the total power source of the entire flipping device and can control the raising or lowering of the device. If an accident occurs, the emergency stop button can be used in time to stop the operation of the flipping device, greatly improving the safety of the device.

[0028] In summary, the utility model has the following beneficial effects:

[0029] 1. Through the setting of the spring fixing device, the effective fixing of the steel door can be realized. When the device body is inserted into the positioning hole, one surface of the second stopper contacts the steel door, and the other surface of the second stopper contacts the fixing spring. The other end of the fixing spring is arranged on the cross beam. After the fixing spring is compressed, it will always apply a pressing force from the cross beam to the second stopper to the steel door, so as to ensure that the second stopper always abuts against the steel door. Since this device is arranged in pairs, the force of the second stoppers on both sides approaching each other clamps the steel door to prevent it from accidentally slipping during the flipping process;

[0030] 2. By setting up the electric motor and the ball screw, the moving platform equipped with the spring fixing device can be raised or lowered along with the ball screw. By changing the height of the steel door through the lifting of the device for fixing the steel door, the steel door with uneven weights on both sides will automatically complete the flipping effect under the action of gravity. At this time, only one person needs to lift or press it from the side to complete the flipping of the steel door, saving the process that originally required six to eight people to cooperate to complete the flipping, and improving the production efficiency while saving labor costs;

[0031] 3. Through the setting of the chamfer at one end of the device body, while ensuring the firmness and tightness of the device body after being inserted into the positioning hole, it is not necessary to align with the positioning hole particularly precisely, and the device body can be inserted into the positioning hole, achieving the effect of accelerating the fixing speed of the steel door.

The power supply VCC is also connected to one end of the resistor R2. The other end of the resistor R2 is connected to one end of the infrared sensor IR2. The other end of the infrared sensor IR2 is connected to one end of the resistor R3. The other end of the resistor R3 is connected to one end of the capacitor C1. The other end of the capacitor C1 is connected to the power supply VCC. The other end of the infrared sensor IR1 is connected to the other end of the infrared sensor IR2.

One end of the normally open contact K1 is also connected to the other end of the resistor R3. The other end of the normally open contact K1 is connected to one end of the resistor R7. The other end of the resistor R7 is connected to one end of the infrared sensor IR5. The other end of the infrared sensor IR5 is connected to the base of the triode Q1.

Through the above circuit, the movement of the steel door can be detected by means of the first infrared sensor, the second infrared sensor, and the third infrared sensor, and whether to raise or lower it can be determined according to whether it is in a balanced state.

[0042] As Figures 1-4As shown, a moving platform 13 is arranged on the ball screw 113, a second through hole is arranged on the cross beam on the side of the moving platform 13 away from the bracket body 11, a spring fixing device 2 is arranged in the second through hole, the spring fixing device 2 comprises a device body 21, a first stopper 22, a second stopper 23 and a fixing spring 24, the first stopper 22 is fixedly connected to one end of the device body 21, the second stopper 23 is fixedly connected to the other end of the device body 21, the fixing spring 24 is sleeved on the device body 21, one end of the fixing spring 24 is fixedly connected to one side of the cross beam, and the fixing spring 24 is sleeved on the device body 21, one end of the fixing spring 24 is fixedly connected to one side of the cross beam, and the fixing spring 24 is sleeved on the device body 21. The other end of the fixed spring 24 is fixedly connected to the side of the second stop block 23 close to the crossbeam. A chamfer 25 is provided at one end of the device body 21. The chamfer 25 is used to assist the device body 21 to enter the positioning hole on the door. The ball screw 113 connected to the motor 3 can convert the rotational motion into linear motion. The spring fixing device 2 can rely on the cooperation of the spring and the second stop block 23 to tighten the steel door from the left and right sides during the cooperation between the device body 21 and the positioning hole to prevent it from falling during the flipping process, thereby effectively improving the safety of the device.

[0043] Specific implementation process: The flipping devices are arranged in pairs and set opposite to each other. There is an installation platform between the two flipping devices. The surface of the installation platform is provided with a soft cushion layer for anti-falling and anti-scratching to prevent damage to the steel door when it comes into contact with the installation platform. The support feet 12 are used to provide support force and stability for the entire flipping device. There are also rollers 5 provided on the support frame 1, which can make a certain adjustment to the position of the flipping device. On the other side of the support frame 1, there is a bottom platform. A moving platform 13 is provided on the support frame 1. The spring fixing device 2 on the moving platform 13 needs to cooperate with the positioning holes on the steel door before the flipping device officially operates. By tightening the first stopper 22, the device body 21 and the second stopper 23 on the device body 21 can be pulled towards the crossbeam, compressing the spring. When the flipping device is moved to a suitable position, the first stopper 22 is slowly released, and the spring will squeeze the device body 21 into the positioning hole of the steel door. There is an inverted chamfer 25 provided on the device body 21, which can facilitate the device body 21 to enter the positioning hole of the steel door without the need for exact alignment. When the spring fixing devices 2 on both sides are positioned, press the switch, and the flipping device can start to operate officially. At this time, since the steel door is placed flat on the installation platform, the infrared sensors on both sides of the moving platform 13 can detect the steel door. Therefore, the control terminal 4 will drive the motor 3 after receiving the signal. The motor 3 rotates the ball screw 113 through the rotating mechanism and converts the rotational motion into a linear motion, driving the moving platform 13 provided on the ball screw 113 to move up and down. When it rises to a certain height, due to the uneven weight ratio at both ends of the steel door, it will naturally tilt. At this time, lift one side of the steel door manually. When the third infrared sensor detects that an object has passed, the control terminal 4 will control the motor 3 to rotate in the reverse direction, causing the moving platform 13 to drive the steel door to slowly descend, and finally making the steel door completely fit with the installation platform and restoring balance. At this time, the motor 3 stops operating, and the device completes the flipping.
