The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
Example 1
Referring to fig. 1 and 2, in the embodiment of the present invention, a safe electric square gate structure includes a valve body 10 installed on a wall, the valve body 10 is provided with a gate 7, a driving mechanism for driving the gate 7 to move up and down is installed at the top end of the gate 7, an auxiliary guide rail 5 is also installed on the outer wall of the wall on the upper side of the valve body 10, two ends of the auxiliary guide rail 5 are respectively installed with a limiting plate 11, a limiting bolt 12 with a travel switch is installed on the limiting plate 11, specifically, the specification of the limiting bolt 12 is not too large according to the selection of the valve caliber, the strength is calculated to ensure that the valve is opened in place, the limiting bolt 12 is loosened upwards to trigger the travel switch fixed on the limiting plate 11, so that the driving mechanism stops operating, and since the position of the limiting is higher than the position where the valve is opened in place by a section, under the condition that the driving mechanism has no problem, this arrangement is inoperative and can only be violated if the drive mechanism fails.
In one aspect of the present invention, a valve body sealing strip 9 is installed on the valve body 10 on the side close to the gate plate 7, and a gate plate sealing strip 8 is installed on the gate plate 7 on the side close to the valve body 10.
In one aspect of the utility model, the driving mechanism comprises an electric device 1, the output end of the electric device 1 is connected with a valve rod nut sleeved on the outer side of a valve rod 6 through a three-jaw piece, one end, far away from the valve rod nut, of the valve rod 6 is connected with a flashboard 7, the valve rod nut is arranged inside the upper portion of a support 2, the valve rod 6 is in trapezoidal threaded connection with the valve rod nut, the three-jaw piece on the valve rod nut is connected with the three-jaw piece at the lower end of the electric device 1, and the support 2 is connected with an embedded steel plate 3 through a bolt.
In one aspect of the utility model, the secondary guide 5 is connected to a primary guide provided on the valve body 10 by means of a connecting bolt.
In one aspect of the utility model, the electric device 1 is mounted on an embedded steel plate 3 fixed on a wall body through a bracket 2, a valve body 10 is connected into a whole through a bolt on the steel plate welded with the embedded steel plate 3 and fixed on a concrete wall, a valve body sealing strip 9 is fixed on the valve body 10 through an inner hexagonal set screw, a gate plate sealing strip 8 is also fixed on a gate plate 7 through the inner hexagonal set screw, a main guide rail and the valve body 10 are integrated, an auxiliary guide rail 5 is connected with the main guide rail on the valve body 10 into a whole through a connecting bolt, and a valve rod 6 is connected with the gate plate 7 through a pin shaft.
Example 2
In another embodiment of the present invention, the difference between this embodiment and the above embodiment is that the valve rod 6 is provided with an intermediate fixed adjusting device 4 in the middle, the intermediate fixed adjusting device determines whether the product is needed according to the elevation (H) of the product, such as the elevation is small, and the intermediate fixed adjusting device can be eliminated, and the device is used for controlling the deflection deformation of the valve rod 6 within the allowable range under the condition of higher elevation.
The working principle of the utility model is as follows: when the gate is opened, the three-jaw piece on the electric device 1 rotates, the valve rod nut is driven to rotate by the three-jaw piece on the valve rod nut, and the valve rod nut cannot move up and down due to the rotation of the valve rod nut, so that the valve rod 6 matched with the valve rod nut moves upwards, and the valve rod 6 drives the gate plate 7 to move upwards together through the pin shaft until the gate plate 7 is completely opened. On the contrary, the principle is also the same, until the flashboard 7 is closed in place, the valve body sealing strip 9 is tightly contacted with the flashboard sealing strip 8 to form a reliable sealing pair, so that the sealing effect is achieved.
