Description

Technical Field

[0001] The utility model relates to the technical field of frequency-changing gates, in particular to a frequency-changing gate with a power-off lifting function. Background Art

[0002] In Chinese Patent Publication (Announcement) No. CN218322495U, a power-off lifting lever mechanism for an unmanned parking lot is mentioned, which mentions that if a power outage occurs when the barrier lever is in a closed state, the barrier lever cannot be lifted normally, and the vehicle is trapped in the parking lot and cannot drive out normally, which brings a lot of trouble to the car owner's parking lot. Its design uses two sets of powerful electromagnets and weights to control the barrier lever, so that the barrier lever is always in a raised state when the power is off. However, power outages are often sudden situations. If the power is off during the process of lifting the lever, its structure is activated, and the weights always press on the gears, increasing the wear of the gears and shortening the service life of the emergency stop mechanism. The weights drive the rack to contact the gear, which will produce a large impact force, causing serious wear on the gears and racks. Its structure is more troublesome to replace. For this reason, we propose a variable channel switch with a power-off lifting lever function that is convenient for replacing emergency stop components. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-6 The utility model provides a technical solution: a channel-changing switch with a power-off lifting function, comprising a control box 1, and also comprising:

[0027] Pin rod 2, pin rod 2 is installed on control box 1;

[0028] The blocking rod 21 is installed on the control box 1 and penetrated by the pin rod 2;

[0029] A trigger mechanism 3, wherein the trigger mechanism 3 is mounted on the control box 1;

[0030] The linkage mechanism 4 is installed on the control box 1 and is connected to the trigger mechanism 3 and the pin rod 2. The trigger mechanism 3 and the linkage mechanism 4 control the barrier rod 21 to be lifted or kept stationary according to the lifting state of the barrier rod 21 when the control box 1 is powered off.

[0031] The trigger mechanism 3 includes a groove 31 opened on the control box 1 , a strong electromagnet 32 ​​is installed on the inner wall of the groove 31 , a metal block 33 is installed on the strong electromagnet 32 ​​, and a rope 34 is installed on the metal block 33 .

[0032] The linkage mechanism 4 includes a gantry 41 mounted on the control box 1, a rotating wheel 42 is mounted on the bottom of the gantry 41, one side of the gantry 41 is connected to the other end of the rope 34, a groove 43 is formed on the top of the gantry 41, a detachable rack 44 is mounted in the groove 43, and a half gear 45 is mounted on the pin 2, and the half gear 45 and the detachable rack 44 can mesh with each other;

[0033] The existence of the rotating wheel 42 can prevent the gantry 41 from causing damage to the control box 1 when it moves.

[0034] A limiting mechanism 5 is installed on the control box 1 , and the limiting mechanism 5 limits the moving track and distance of the gantry 41 .

[0035] The limiting mechanism 5 includes a fixed block 51 installed on the control box 1, the fixed block 51 is located in the middle of the gantry 41, and also includes a limiting frame 52 installed on the periphery of the gantry 41, the limiting frame 52 is fixedly connected to the control box 1, a hole 53 is opened on the limiting frame 52, the hole 53 is penetrated by the pin rod 2, and a hole 2 54 with the same shape as the detachable rack 44 is opened on the limiting frame 52; when the staff is performing maintenance, they can directly observe the wear of the half gear 45 and the detachable rack 44 through the hole 2 54, so as to judge whether they need to be replaced. The diameter of the hole 2 54 is larger than the pin rod 2, and the staff can also use tools to directly replace the half gear 45 from the hole 2 54.

[0036] The limiting frame 52 limits the gantry 41 to always move inside the limiting frame 52 .

[0037] A slot 55 is provided on the gantry 41, and clamping rods 56 are installed at both ends of the detachable rack 44, and the clamping rods 56 and the slot 55 fit together; when the detachable rack 44 needs to be replaced, it is only necessary to use a strong magnet block to insert it from the hole 54 to remove the detachable rack 44, and then fit the new detachable rack 44 into the hole 54 and press downward, so that the clamping rods 56 at both ends of the detachable rack 44 fit into the slot 55 on the gantry 41, and the replacement is completed.

[0038] A support rod 57 is installed on the gantry 41, and a sleeve 58 is installed on the support rod 57. The sleeve 58 prevents the rope 34 from directly contacting the control box 1, thereby protecting the control box 1 from damage.

[0039] The rope 34 is made of metal and is located above the sleeve 58 . The metal material enables the rope 34 to withstand the impact force when the metal block 33 falls.

[0040] The fixing block 51 and the gantry 41 are provided with a rubber sheet 6 opposite to each other.

[0041] When the power supply system is normal, the control box 1 provides power to the powerful electromagnet 32. At this time, the rack and the half gear 45 on the gantry 41 are not engaged, and the control box 1 normally controls the rise and fall of the barrier rod 21 to ensure the normal operation of the unmanned parking lot.

[0042] When the power is suddenly cut off, the strong electromagnet 32 ​​loses its attraction to the metal block 33, and the metal block 33 naturally falls down under the action of gravity, thereby driving the rope 34 to pull the gantry 41 to move horizontally, and the detachable rack 44 on the gantry 41 moves with the gantry 41. If the railing is in the intercepting state at this time, the half gear 45 on the pin rod 2 is in the closest but non-contacting state with the rack, and as the detachable rack 44 moves, the detachable rack 44 engages with the half gear ring, thereby driving the pin rod 2 to rotate, thereby lifting the blocking rod 21. After the blocking rod 21 is lifted, the gantry 41 and the fixed block 5 1 fits, the rubber sheet 6 reduces its impact force, and with the restriction of the fixed block 51, the friction generated by the continuous engagement of the rack on the gantry 41 and the half gear 45 can be alleviated to a large extent. At this time, the blocking rod 21 is fixed in a raised state. When the blocking rod 21 is half-raised, the blocking rod 21 will also drive the pin rod 2 to rotate a certain angle. At this time, the half gear ring also has a certain angle, and the detachable rack 44 is engaged with the rear part of the half gear ring to lift the blocking rod 21. If the blocking rod 21 is already in a raised state, the detachable rack 44 will directly pass through the side of the half gear ring without teeth, and will not affect the blocking rod 21.
