Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, specifically to a safety check-in device for a mixing plant construction. Background Technology

[0002] The safety check-in device for batching plants is a device used in batching plants to activate or deactivate the mixing function by activating a check-in device. Traditional batching plants generally use ordinary switches to start and stop the mixing machine. Due to the large number of personnel moving around the batching plant, non-construction personnel can easily accidentally touch the traditional mixing machine switch to start or stop the mixing machine, thus affecting the start and stop of the mixing machine. The mixing machine is heavy, and if it is accidentally started, it can easily cause a safety accident. Existing batching plants use check-in devices to start and stop the mixing machine, avoiding the problem of operators still being inside the mixing equipment due to other workers accidentally starting it, thus eliminating the safety hazards for operators. However, in existing check-in devices, magnetic cards are generally used in conjunction with magnetic suction mechanisms to start and stop. Construction personnel can use a special magnetic card to start and stop the mixing device. Although this existing check-in device requires a magnetic card to start or stop the mixing machine, it can sense and start or stop the mixing machine when the magnetic card comes into contact with this magnetic suction mechanism. It is highly sensitive. If the construction personnel accidentally touch the magnetic suction mechanism with the magnetic card, it can easily cause the switch to be accidentally activated, resulting in low safety performance and possible errors in command transmission. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a construction safety check-in device for a mixing plant. This device can prevent construction personnel from accidentally turning on the mixing machine, has higher safety performance, more accurate command transmission, and a simple structure.

[0004] To achieve the above objectives, this utility model provides a construction safety check-in device for a mixing plant, including a mixing machine, a check-in device, and a platform for placing the check-in device. The check-in device is electrically connected to the mixing machine. The check-in device includes a housing with a card slot. A pressing platform is provided in the card slot and can reciprocate within the card slot. A sliding mechanism is provided between the pressing platform and the inner wall of the card slot. A magnetic induction area is provided at the lower end of the pressing platform for generating magnetic induction with a magnetic card. A driver is provided between the magnetic induction area and the mixing machine for driving the mixing machine to mix.

[0005] The effects of adopting the above technical solution are as follows: The placement of the card reader on the mixer makes the installation of the card reader more stable; the use of a pressing platform on the card slot ensures that the magnetic card can only enter the magnetic induction area after being pressed, effectively preventing accidental activation or deactivation of the mixer; the sliding mechanism between the pressing platform and the inner wall of the card slot allows the pressing platform to slide more smoothly when pressed; when the pressing platform is pressed to the magnetic induction area, the magnetic card can be sensed and a signal can be transmitted to the driver to drive the start and stop of the mixer, resulting in more accurate transmission of commands, higher safety performance, prevention of accidental activation, and simple structure for convenient operation.

[0006] The present invention further includes: a sensing column in the magnetic induction area, a sensing contact end in the end of the sensing column facing the pressing table, and an anti-collision pad in the lower end face of the pressing table corresponding to the sensing contact end, the anti-collision pad being able to contact the sensing contact end.

[0007] The effects of adopting the above technical solution are as follows: by setting an induction column in the magnetic induction area and setting an induction contact area on the induction column, it can be used to sense the position of the pressing table. When the induction contact end contacts the pressing table, the induction column can issue a corresponding command to start or stop the mixer or start other functions. By setting an anti-collision rubber pad on the lower end of the pressing table corresponding to the induction contact end, the anti-collision rubber pad can contact the induction contact end, avoiding damage to the pressing table or the induction contact end from repeated pressing and impact, thus improving service life and simplifying the structure.

[0008] The present invention further comprises: the card slot is a card slot with a quadrilateral cross-section; the sliding mechanism includes four slide rails with openings at the connection points of the four side walls of the card slot and arranged in the same direction as the opening of the card slot; and a reset member is provided between the pressing table and the end of the slide rails.

[0009] The effect of adopting the above technical solution is that the card slot with a quadrilateral cross-section can better fit the shape of the quadrilateral magnetic card. In this solution, the quadrilateral cross-section means that the position for placing the magnetic card is a quadrilateral, not a complete closed quadrilateral. In other solutions, those skilled in the art can also make the cross-section of the card slot quadrilateral by setting slide rails of different shapes. Setting four slide rails can make the sliding of the pressing table more uniform and more stable. The reset button can be set so that the pressing table can be reset after being pressed. The structure is simple and the reset effect is good.

[0010] The present invention further comprises: the reset component is a reset spring, one end of the reset spring is connected to the end of the slide rail, the other end is connected to the lower end face of the pressing table, and the outer wall of the reset spring is in contact with the inner peripheral wall of the slide rail.

[0011] The effects of adopting the above technical solution are as follows: By setting a reset spring, when the pressing platform is pressed, the reset spring can also be compressed and deformed. At this time, the reset spring will generate a reverse thrust under the influence of pressure, so that the pressing platform is reset. The reset method is simple. By making the reset spring contact with the inner circumferential wall of the slide rail, the reset spring is not easy to fall off the slide rail after being compressed and deformed. The reset spring can contact and abut against the inner wall of the slide rail, and the inner circumferential wall of the slide rail can support the reset spring, making the reset spring less prone to damage and improving its service life.

[0012] The present invention further includes: a recess for fingerprint recording is provided on the side wall of the housing corresponding to the card slot position, and the recess is electrically connected to the sensing post.

[0013] The effects of adopting the above technical solution are as follows: by setting a recessed area, the fingerprint registration function of the recessed area works in conjunction with the pressing platform, and the dual switch restricts the opening and closing of the mixer, preventing the mixer from being accidentally touched by non-workers. In this solution, those skilled in the art can place the magnetic card on the pressing platform and press the pressing platform, and then use the remaining finger to press the recessed area to register the fingerprint to start or stop the mixer. The structure is simple, effectively reduces accidental touch by non-construction personnel, and improves safety performance.

[0014] The present invention further includes: a circumferential indicator light strip is provided at the opening of the slot, and a gravity switch is provided at the inductive contact end for connecting with the indicator light strip; the indicator light strip and the gravity switch are electrically connected.

[0015] The effect of adopting the above technical solution is that by setting an indicator light strip around the opening of the card slot, the light will illuminate after the pressing table contacts the gravity switch at the sensing contact end and the gravity switch is pressed, indicating to the operator that the pressing is in place, avoiding damage to the equipment due to excessive pressing. The structure is simple and the indication effect is obvious.

[0016] The present invention is further provided with a display on the housing.

[0017] The effects of adopting the above technical solution are: using a display screen allows data to be presented more intuitively to construction workers, information display is more intuitive, and the structure is simple. Attached Figure Description

[0021] An embodiment of the safety check-in device for a mixing plant construction according to this utility model is shown in the figure. To achieve the above-mentioned objective, this utility model provides a safety check-in device 2 for a mixing plant construction, including a mixing machine 1, a check-in device 2, and a platform 3 for placing the check-in device 2. The check-in device 2 is electrically connected to the mixing machine 1. The check-in device 2 includes a housing 4, on which a card slot 5 is provided. A pressing platform 6 is provided in the card slot 5. The pressing platform 6 can reciprocate in the card slot 5. A sliding mechanism is provided between the pressing platform 6 and the inner wall of the card slot 5. A magnetic induction area 7 is provided at the lower end of the pressing platform 6 for generating magnetic induction with a magnetic card. A driver 8 for driving the mixing machine 1 to mix is ​​provided between the magnetic induction area 7 and the mixing machine 1. A platform 3 is installed on the mixer 1 to hold the card reader 2, making the installation of the card reader 2 more stable. A pressing platform 6 is installed on the card slot 5 so that the magnetic card can only enter the magnetic induction area 7 after being pressed, which can more effectively prevent accidental activation or deactivation of the mixer 1. A sliding mechanism is installed between the pressing platform 6 and the inner wall of the card slot 5 so that the pressing platform 6 slides more smoothly when pressed. When the pressing platform 6 is pressed into the magnetic induction area 7, the magnetic card can be sensed and a signal can be transmitted to the driver 8 to drive the start and stop of the mixer 1. The transmission command is more accurate, the safety performance is higher, accidental activation is avoided, and the structure is simple and easy to operate. The magnetic induction area 7 is equipped with an induction column 9, with one end of the induction column 9 facing the pressing platform 6. A sensing contact end 10 is provided. A shock-absorbing rubber pad 11 is provided on the lower end face of the pressing platform 6 corresponding to the sensing contact end 10. The shock-absorbing rubber pad 11 can contact the sensing contact end 10. A sensing column 9 is provided in the magnetic induction area 7, and a sensing contact area is provided on the sensing column 9 to sense the position of the pressing platform 6. When the sensing contact end 10 contacts the pressing platform 6, the sensing column 9 can issue a corresponding command to start or stop the mixer 1 or activate other functions. The shock-absorbing rubber pad 11 on the lower end face of the pressing platform 6 corresponding to the sensing contact end 10 can contact the sensing contact end 10, avoiding damage to the pressing platform 6 or the sensing contact end 10 from repeated pressing and impact, thus improving service life. The slot 5 has a four-sided cross-section. The card slot 5 is shaped like a card slot. The sliding mechanism includes four slide rails 12 with openings at the connection points of the four side walls of the card slot 5 and arranged in the same direction as the openings of the card slot 5. A reset element is provided between the pressing table 6 and the end of the slide rail 12. The card slot 5 with a quadrilateral cross-section can better adapt to the shape of the quadrilateral magnetic card. In this solution, the quadrilateral cross-section means that the position for placing the magnetic card is a quadrilateral, not a complete quadrilateral with four closed sides. In other solutions, those skilled in the art can also make the cross-section of the card slot 5 quadrilateral by setting slide rails 12 of different shapes. Setting four slide rails 12 can make the sliding of the pressing table 6 more uniform and more stable. And setting a reset button can reset the pressing table 6 after pressing.The reset component is a reset spring 13. One end of the reset spring 13 is connected to the end of the slide rail 12, and the other end is connected to the lower end face of the pressing platform 6. The outer wall of the reset spring 13 contacts the inner peripheral wall of the slide rail 12. By using the reset spring 13, when the pressing platform 6 is pressed, the reset spring 13 can also be compressed and deformed. At this time, the reset spring 13 will generate a reverse thrust under the influence of pressure, so that the pressing platform 6 resets. The reset method is simple, and the contact between the reset spring 13 and the inner peripheral wall of the slide rail 12 can... This ensures that the return spring 13 is not easily dislodged from the slide rail 12 after deformation under pressure. The return spring 13 can contact and abut against the inner wall of the slide rail 12, and the inner peripheral wall of the slide rail 12 can support the return spring 13, making the return spring 13 less prone to damage. The side wall of the housing 4 is provided with a recess 14 for fingerprint enrollment at the position corresponding to the slot 5. The recess 14 is electrically connected to the sensing column 9. The recess 14 is designed to allow the fingerprint enrollment function of the recess 14 to cooperate with the pressing platform 6, and the dual switch restricts the mixer 1. To prevent accidental activation of the mixer 1 by unauthorized personnel, this solution allows skilled personnel to place a magnetic card on the pressing platform 6 and press it, then use their remaining fingers to press the recess 14 to register their fingerprint and start or stop the mixer 1. This simple structure effectively reduces accidental activation by non-construction personnel and improves safety. A circumferential indicator light strip 16 is provided at the opening of the card slot 5, and a gravity switch 15 is provided at the sensing contact end 10 to activate the indicator light strip 16. The indicator light strip 16 and gravity switch 15 are electrically connected. The circumferential indicator light strip 16 at the opening of the card slot 5 ensures that the pressing platform 6 contacts the gravity switch 15 at the sensing contact end 10, and the light illuminates when the switch 15 is pressed, indicating that the operator has pressed the correct position, preventing damage to the equipment from excessive pressure. This simple structure provides a clear indication. A display 17 is provided on the housing 4, allowing data to be presented more intuitively to construction personnel, providing a more direct and simple information display.In implementation, the construction worker can place a special magnetic card for starting and stopping the mixer 1 on the pressing platform 6 in the card slot 5. At this time, the magnetic card will not yet contact the magnetic induction area 7. Since the pressing platform 6 can slide in the card slot 5, the construction worker can press the magnetic card to make the pressing platform 6 slide in the card slot 5 and reach the magnetic induction area 7 to contact the sensing contact end 10 of the sensing column 9. At this time, the magnetic card can generate magnetic induction with the magnetic induction area 7 and transmit the corresponding signal to the mixer 1 for starting and stopping the mixer 1. Since the signal transmission requires a signal transmitter, which is a conventional technology in the field, those skilled in the art can set one or more components for signal transmission to assist signal transmission as needed. After the construction worker presses the pressing platform 6 with the magnetic card, they then press their pre-registered fingerprint finger into the recess 14. The fingerprint and magnetic card arrive at the designated position simultaneously to start and stop the mixer 1. When a person skilled in the art presses the button to start or stop the mixer 1, and then releases the pressing platform 6, the reset spring 13 in the slide rail 12 can reset the pressing platform 6 to its initial position. The reset method is simple, and the use of multiple start and stop conditions can reduce the probability of accidental start and stop of the mixer 1, thus reducing the occurrence of accidental activation. Moreover, this structure is easy to operate. The display 17 in this solution can be used to display data. A person skilled in the art can set the data that needs to be displayed intuitively to understand the status of the mixer 1 or the card-swiping device 2. The indicator light strip 16 at the opening of the card slot 5 can be activated after the pressing platform 6 is pressed, causing the gravity switch 15 to move under pressure. This can send a signal to the construction personnel that the pressing is in place, avoiding excessive pressing of the pressing platform 6 and damage to the card-swiping device.
