Description

Technical Field

[0001] The utility model relates to the technical field of sliding door machines, in particular to a sliding door machine with a stable structure. Background Art

[0002] Protective doors are widely used in nuclear-related process rooms or laboratories, such as those used in large nuclear facilities, irradiation processing, radioactive waste disposal, and radioactive source storage. Because protective doors are very heavy, they require a sliding door actuator to open and close. For example, Chinese Utility Model Patent Publication No. CN213175258U proposes a structurally stable sliding door actuator. The sliding frame of this sliding door actuator is driven by a belt, ensuring smooth transmission and preventing jerks caused by motor startup and shutdown. The design of the mounting frame and sliding frame also enhances the structural strength of the sliding door actuator, resulting in a relatively stable structure.

[0003] However, the above-mentioned sliding door machine requires motor 1 to stop moving after the protective door reaches the door frame. The torque of motor 2 drives gear 2 to rotate after being changed by reducer 2. The rotation of gear 2 drives the sector teeth to rotate, and the rotation of the sector teeth drives the connecting plate to rotate. The transmission structure transmits the torque to both ends of the protective door, so that the protective door is close to the wall at the same time, so that the protective door seals the door gap; however, the above-mentioned mechanism for driving the protective door close to the door frame is relatively complicated, and the protective door is only pushed horizontally, resulting in a gap between the bottom of the protective door and the door frame, resulting in the risk of radiation leakage through the gap. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a sliding door machine with a stable structure and high safety, which can reduce the gap between the protective door and the ground, thereby reducing the risk of radiation leakage.

[0005] The cam is mounted on the front of the door frame and the cam is moved along the top of the door frame so that the cam can be moved along the top of the door frame when the cam is in the closed position. When the protective door is closed, the slide moves along the fixed plate toward the door frame until it is aligned with the door frame. The pushing assembly pulls the mounting plate toward the door frame, causing multiple sliders to slide toward a lower position along multiple inclined rails respectively, causing the mounting plate to drive the protective door to move inward and downward, so that the side wall of the protective door is in sealed contact with the door frame, and at the same time, the bottom of the protective door is in sealed contact with the bottom of the door frame, thereby achieving comprehensive sealed contact between the protective door and the door frame, which can reduce the gap between the protective door and the ground, reduce the risk of radiation leakage, and provide high safety.

[0006] Preferably, the pushing assembly includes a push cylinder and a push plate, the fixed end of the push cylinder is installed on the slide, the push cylinder is parallel to the inclined slide rail, the push plate is installed on the mounting plate, and the piston rod of the push cylinder is connected to the push plate; the piston rod of the push cylinder extends to push the push plate to drive the mounting plate to move, so that the mounting plate drives multiple sliders to move along multiple inclined slide rails to a high position, thereby opening the protective door, and the piston rod of the push cylinder contracts to drive the push plate to drive the mounting plate to move, so that the mounting plate drives multiple sliders to move along multiple inclined slide rails to a low position, thereby closing the protective door. The structure is simple and the driving effect is good.

[0007] Preferably, the pushing assembly includes a top plate, a cam, a lever, a first block and a second block, the top plate is mounted on the mounting plate, the cam is rotatably mounted on the slide via a rotating shaft, a lever is provided on the side of the cam away from the top plate, the lever and the protrusion of the cam are inclined, the first block and the second block are mounted on the fixed plate, the first block and the second block are both located above the door frame, the length of the second block is greater than the length of the first block, the second block is located on the side facing the lever, the first block is located on the other side of the lever, and the end of the lever is aligned with the side of the second block; when the protrusion of the cam contacts the top plate, the cam pushes the top plate outward, so that the top plate drives the mounting plate and the plurality of sliders to move to the high position of the inclined slide rail, at which time the protective door is opened from the door frame. When the protective door moves to the door frame, the end of the driving rod passes the outer end of the block one and is blocked by the stop block two, so that the driving rod drives the cam to rotate, and the protruding part of the cam disengages from the top plate, so that the protective door drives the mounting plate and multiple sliders to slide to a lower position along the multiple inclined slide rails under the action of its own weight, so that the protective door is pressed tightly against the outer wall and the ground under the action of its own weight, and at this time the end of the driving rod extends between the block one and the stop block two. When the protective door moves to open, the end of the driving rod is blocked by the block one, thereby driving the cam to rotate, so that the protruding part of the cam pushes the top plate to the high position of the inclined slide rail again, so that the protective door is separated from the door frame and the protective door is separated from the outer wall and the ground. No power is required, the structure is simple, and the practicality is good.

[0008] Preferably, it also includes two horizontal plates, two slide rails 2 and multiple sliders 2, the two horizontal plates are installed in parallel on the fixed plate, the two slide rails 2 are installed in parallel on the two horizontal plates, the end faces of the two horizontal plates are set upward, the multiple sliders 2 are slidably installed on the two slide rails 2, and the multiple sliders 2 are installed on the slide; the slide is slidably installed on the two slide rails 2 through the multiple sliders 2, the two horizontal plates support the two slide rails 2, and the end faces of the two slide rails 2 face upward, so that the two slide rails 2 lift the slide through the multiple sliders 2, thereby improving the structural stability.

[0009] Preferably, it also includes longitudinal beams and cross beams, the longitudinal beams are vertically installed on the slide, and the cross beams are horizontally installed on the longitudinal beams, and the high outer ends of multiple inclined slide rails are connected to the cross beams; the longitudinal beams and cross beams provide auxiliary support for the multiple inclined slide rails to improve the structural stability of the multiple inclined slide rails.

[0010] Preferably, it also includes a drive shaft and a motor, the drive shaft is rotatably mounted on the slide, the motor is mounted on the fixed plate, the output shaft of the motor is transmission-connected to the drive shaft, and the slide and the drive shaft are transmission-connected via a transmission assembly; the motor drives the drive shaft to rotate, and the drive shaft drives the slide to move along the fixed plate via the transmission assembly, which has large driving force and good practicality.

[0011] Preferably, the transmission assembly includes a spiral groove and a slide rod. The spiral groove is arranged on the outer wall of the drive shaft. The pitch of the middle part of the spiral groove is greater than the pitch at both ends. The slide rod is installed on the slide, and the end of the slide rod extends into the spiral groove; when the drive shaft rotates, it drives the spiral groove to rotate, and the side wall of the spiral groove is in friction contact with the side wall of the slide rod, thereby pushing the slide rod to move along the axial direction of the drive shaft, and the slide rod drives the slide to move. Since the pitch at both ends of the spiral groove is small, the effect of slow acceleration and slow deceleration is achieved, thereby avoiding the setbacks caused when the protective door starts and stops, and also protecting the motor.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: when the protective door is opened away from the door frame, the pushing assembly pushes the mounting plate in a direction away from the door frame, so that the multiple sliders slide to a high position along the multiple inclined slide rails respectively, so that the mounting plate drives the protective door to move outward and upward, so that a gap is formed between the side wall of the protective door and the door frame, and at the same time, a gap is formed between the bottom of the protective door and the bottom of the door frame, and the slide moves along the fixing plate in a direction away from the door frame, thereby preventing the protective door from contacting the ground and the wall, and improving the stability of the protective door when moving;

[0013] When the protective door is closed close to the door frame, the slide moves along the fixed plate toward the door frame until it is aligned with the door frame. The pushing assembly pulls the mounting plate toward the door frame, causing multiple sliders to slide to a lower position along multiple inclined slide rails, so that the mounting plate drives the protective door to move inward and downward, so that the side wall of the protective door is in sealed contact with the door frame, and at the same time, the bottom of the protective door is in sealed contact with the bottom of the door frame, thereby achieving comprehensive sealed contact between the protective door and the door frame, reducing the gap between the protective door and the ground, reducing the risk of radiation leakage, and improving safety.

[0024] The slide 2 is slidably mounted on the two slide rails 2 15 through multiple sliders 2 16, and the two cross plates 14 support the two slide rails 2 15. The end surfaces of the two slide rails 2 15 face upward, so that the two slide rails 2 15 lift the slide 2 through the multiple sliders 2 16, and the longitudinal beams 17 and the cross beams 18 provide auxiliary support for the multiple inclined slide rails 4, thereby improving the structural stability of the multiple inclined slide rails 4. When the protective door 3 is opened away from the door frame, the piston rod of the push cylinder 7 extends to push the push plate 8 to drive the mounting plate 6 to move, so that the mounting plate 6 drives the multiple sliders 1 5 to move to the high position along the multiple inclined slide rails 4, and pushes the mounting plate 6 in the direction away from the door frame, so that the multiple sliders 1 5 slide to the high position respectively along the multiple inclined slide rails 4, so that the mounting plate 6 drives the protective door 3 to move to the outside and upward, so that the side wall of the protective door 3 and the door frame are When the protective door 3 is closed, the slide 2 moves along the fixed plate 1 toward the door frame until it is aligned with the door frame.

[0026] like Figures 5 and 6 As shown, on the basis of Example 1, the pushing assembly includes a top plate 9, a cam 10, a shift rod 11, a stop block 12 and a stop block 2 13. The top plate 9 is mounted on the mounting plate 6. The cam 10 is rotatably mounted on the slide 2 through a rotating shaft. The shift rod 11 is provided on the side of the cam 10 away from the top plate 9. The shift rod 11 and the protrusion of the cam 10 are inclined. The stop block 12 and the stop block 2 13 are mounted on the fixed plate 1. Both the stop block 12 and the stop block 2 13 are located above the door frame. The length of the stop block 2 13 is greater than that of the stop block 12.

The slide rod 22 is mounted on the slide 2, and the end of the slide rod 22 extends into the spiral groove 21.

[0030] The motor 20 drives the drive shaft 19 to rotate, and the drive shaft 19 drives the spiral chute 21 to rotate. The side walls of the spiral chute 21 are in frictional contact with the side walls of the slide rod 22, thereby pushing the slide rod 22 to move along the axial direction of the drive shaft 19, and the slide rod 22 drives the slide 2 to move. Since the pitch at both ends of the spiral chute 21 is small, the effect of slow acceleration and slow deceleration is achieved, avoiding the setbacks caused by the start and stop of the protective door 3, and also protecting the motor 20.

[0031] like Figures 1 to 6As shown, the present invention is a sliding door machine with a stable structure.

Then the motor 20 drives the driving shaft 19 to rotate, and the driving shaft 19 drives the spiral slide 21 to rotate. The side wall of the spiral slide 21 is in friction contact with the side wall of the slide rod 22, thereby pushing the slide rod 22 to move along the axial direction of the driving shaft 19, and the slide rod 22 drives the slide 2 moves along the fixed plate 1 in the direction away from the door frame, and then due to the small pitch of the two ends of the spiral slide 21, the effect of slow acceleration and slow deceleration is achieved, and the protective door 3 is prevented from contacting the ground and the wall. Finally, when the protective door 3 approaches the door frame and is closed, the slide 2 moves along the fixed plate 1 in the direction of the door frame until it is aligned with the door frame, pushing the assembly to act, so that the multiple sliders 5 slide to the lower position along the multiple inclined slide rails 4 respectively, so that the mounting plate 6 drives the protective door 3 to move inward and downward, so that the side wall of the protective door 3 is in sealing contact with the door frame, and at the same time, the bottom of the protective door 3 is in sealing contact with the bottom of the door frame, so that the protective door 3 is in full sealing contact with the door frame.
