Description

Technical Field

[0001] The invention belongs to the technical field of water conservancy facilities, and in particular relates to a mechanical self-locking device for a gate. Background Art

[0002] The traditional method of locking the gate when opening by manually moving the locking beam has the following defects:

[0003] 1. It is easy to produce deviations, resulting in incomplete cooperation with the locking plate, posing a safety hazard.

[0004] 2. As the orifice increases and the weight of the gate increases, the weight of the locking beam will increase, and manual handling will be extremely laborious.

[0005] 3. The locking beam is usually placed on the top of the pier when not in use, and it is inevitable that it will fall into the water or be stolen.

[0006] In order to solve the above problems, people invented a self-locking device to replace the traditional locking beam. The patent with publication number CN104088257A discloses an automatic gate locking device that can realize automatic locking and unlocking by lifting and lowering the gate. However, the device still has some defects: in order to meet the movement requirements of the locking rod, the two sides of the gate need to be designed to avoid, so as to provide sufficient movement space for the locking rod. This will change the structure and mechanical properties of the original gate, increase the design cost, and is not convenient for direct application on the basis of the existing gate.

[0035] The technical solutions in the embodiments of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] like Figures 1 to 9 As shown, the present invention provides a gate mechanical self-locking device, including matching components 4 arranged at both ends of the gate 1, a support 9 arranged on the gate slot pier 2, and a self-locking member 3 rotatably installed on the support 9 through a rotating shaft 8.

[0037] As a preferred example, the matching assembly 4 includes a locking matching piece 12, an unlocking matching piece 13 and a resetting matching piece 14. The locking matching piece 12, the unlocking matching piece 13 and the resetting matching piece 14 are fixedly mounted on both ends of the gate 1 by welding or fasteners.

[0038] The self-locking member 3 includes a locking block 5, an unlocking block 6 and a reset block 7. The rotating shaft 8 is rotatably mounted on the support 9. The locking block 5, the unlocking block 6 and the reset block 7 are all fixedly mounted on the rotating shaft 8. It should be noted that the locking block 5 needs to bear weight, that is, to support the gate 1, while the unlocking block 6 and the reset block 7 are only operating members and do not need to bear weight. Therefore, the weight and strength of the locking block 5 are greater than those of the unlocking block 6 and the reset block 7.

[0039] As a preferred example, the locking fitting 12 is a snap fitting, and the locking shift block 5 has a right-angle abutting end that matches the snap fitting surface of the locking fitting 12 .

[0040] As a preferred example, the locking fitting 12, the resetting fitting 14 and the unlocking fitting 13 are arranged in descending order, and their respective movement tracks do not overlap. Figure 3 As shown, the locking block 5 is arranged at an angle of 180° with the reset block 7 and at an angle of 45° with the unlocking block 6, and the three are arranged in a one-to-one correspondence with the locking fitting 12, the unlocking fitting 13 and the reset fitting 14 in the axial direction. The locking block 5 is located at the center of the rotating shaft 8, the unlocking block 6 is located at the left end of the rotating shaft 8, and the reset block 7 is located at the right end of the rotating shaft 8.

[0041] As a preferred example, in order to limit the movement position of the locking block 5, a first limiter 11 and a second limiter 10 are provided on the support 9, the first limiter 11 limits the position of the locking block 5 when it rotates counterclockwise, and the second limiter 10 limits the position of the locking block 5 when it rotates clockwise.

[0042] As a preferred example, in order to ensure normal movement between the mating component and the self-locking member 4 , the maximum rotation radius R1 of the locking block 5 is greater than the distance W1 between the end surface of the locking mating member 12 and the center line of the rotating shaft 8 .

[0043] The maximum rotation radius R2 of the unlocking block 6 is larger than the distance W2 between the end surface of the unlocking fitting 13 and the center line of the rotating shaft 8 , and smaller than the distance W between the end surface of the gate 1 and the center line of the rotating shaft 8 .

[0044] The maximum rotation radius R3 of the reset block 7 is larger than the distance W3 between the end surface of the reset fitting 14 and the center line of the rotating shaft 8 , and smaller than the distance W between the end surface of the gate 1 and the center line of the rotating shaft 8 .

[0045] like Figures 4 to 6As shown, when the gate 1 is in the closed state, the self-locking member 3 is in the initial state. When the gate is opened, the hoist drives the gate 1 to rise to the fully opened height. In this process, the matching component 4 drives the self-locking member 3 to rotate clockwise, that is, the locking matching member 12 contacts the locking block 5 and lifts it. When the end of the locking block 5 passes over the locking matching member 12, it will rotate under the action of gravity. At this time, since the gap between the two ends of the gate 1 is not enough to lock the block 5 back to the initial state, the end of the locking block 5 abuts against the side of the locking matching member 12. At this time, the gate 1 is appropriately lowered by a certain distance so that the end of the locking block 5 abuts against the buckle surface on the locking matching member 12. At this time, the gate 1 is supported by the locking block 5 and cannot be lowered, that is, the locking block 5 locks the gate 1.

[0046] like Figures 7 to 9 As shown, when the gate needs to be closed, the gate 1 is appropriately lifted to a certain limit height. During this process, the matching component 4 drives the self-locking part 3 to rotate clockwise, that is, the unlocking matching part 13 contacts the unlocking block 6 and lifts it up. When the locking block 5 rotates to the right side of the shaft 8 and the torque is greater than the left side, the self-locking part 4 will continue to rotate until it is unlocked.

[0047] At this time, the reset block 7 is tilted, and in the process of lowering the gate 1 to the closing height, the matching component 4 drives the self-locking part 3 to rotate counterclockwise, that is, the reset matching part 14 contacts the reset block 7 and presses it down. When the end of the reset matching part 14 completely passes over the reset block 7, the left torque of the rotating shaft 8 is greater than the right torque. At this time, the self-locking part 4 will continue to rotate until it returns to the initial state.

[0048] During the process of opening and closing the gate 1, the rotation of the self-locking member 4 comes from the driving force generated when the gate 1 is raised and lowered, and no manual operation is required, making the opening and closing operations more convenient and the locking of the gate 1 more reliable.

[0049] The matters not described in detail in the present invention are all known technologies to those skilled in the art.

[0050] It should be noted that the above specific implementation methods are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified and replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
