Description

Technical Field

[0001] The utility model relates to the technical field of pump gates, in particular to a self-locking stoplog gate. Background Art

[0002] The inspection gate is mainly used for the inspection and maintenance of integrated pump gates. The inspection gate is generally divided into multiple stoplog gates for easy use and storage. Because each stoplog gate is relatively short, multiple stoplog gates need to be connected when used.

[0003] When using the existing stoplog gate, a complex structure is required to connect multiple stoplog gates, which is complicated to operate and time-consuming, resulting in a waste of operating time and a reduction in work efficiency. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that when using a stoplog gate, a complex structure needs to be used to connect multiple stoplog gates, which is complicated and time-consuming to operate, resulting in a waste of operating time and thus reduced work efficiency, and to propose a self-locking stoplog gate.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a self-locking stoplog gate, comprising a stoplog gate, a guide cone is installed on the top of the stoplog gate, a guide sleeve is installed on the bottom of the stoplog gate, upper hooks are installed at both ends of the top of the stoplog gate, and bottom hooks are installed at both ends of the bottom of the stoplog gate, and the upper hooks are hooked with the bottom hooks.

[0006] Preferably, a rotating shaft passes through the middle of the upper hook, and a handle is connected to the bottom of the upper hook.

[0007] Preferably, a connecting ring is installed on the inner side of the upper hook, and a mounting plate is installed on one end of the rotating shaft.

[0008] Preferably, the top outer surface of the upper hook is provided with a first inclined surface, and the bottom outer surface of the bottom hook is provided with a second inclined surface.

[0009] Compared with the prior art, the advantages and positive effects of the present invention are:

[0010] In the present invention, when two stopgates are connected, the upper stopgate is pressed down, and the upper hook is rotated toward the middle of the stopgate by the first inclined surface until it hooks the bottom hook, thereby completing self-locking. When the stopgate is disconnected after use, the stopgate needs to be lifted and placed vertically on the ground so that the upper hook and the bottom hook are in a relaxed state, and then the handle is pulled down, and then the upper stopgate is lifted again to complete the disassembly of the lowest stopgate, and the remaining stopgates are removed by analogy, which facilitates the lifting of the stopgates after maintenance and ensures that all the stopgates can be lifted after maintenance, preventing the lower stopgates from being unable to be lifted, thereby improving the efficiency of maintenance work. At the same time, the self-locking of the stopgate can be manually released after it is lifted, and multiple stopgates can be connected as needed, thereby improving the convenience of operation.

[0017] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0018] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Example 1: Figure 1-Figure 5As shown, the utility model provides a technical solution: a self-locking stoplog gate, comprising a stoplog gate 1, a guide cone 2 is installed on the top of the stoplog gate 1, a guide sleeve 3 is installed on the bottom of the stoplog gate 1, upper hooks 4 are installed at both ends of the top of the stoplog gate 1, bottom hooks 5 are installed at both ends of the bottom of the stoplog gate 1, the upper hook 4 is hooked with the bottom hook 5, a rotating shaft 6 passes through the middle of the upper hook 4, a handle 8 is connected to the bottom of the upper hook 4, a connecting ring 7 is installed on the inner side of the upper hook 4, a mounting plate 9 is installed on one end of the rotating shaft 6, a first inclined surface 10 is provided on the outer surface of the top of the upper hook 4, and a second inclined surface 11 is provided on the outer surface of the bottom of the bottom hook 5.

[0020] In this embodiment, by installing the guide cone 2 inside the guide sleeve 3, the connection of the two stoplog gates 1 is positioned by the guide cone 2 and the guide sleeve 3, which facilitates the connection and installation of multiple stoplog gates 1, thereby improving the accuracy of the connection of the stoplog gates 1. After the two stoplog gates 1 are lowered, the upper hook 4 and the bottom hook 5 form a self-locking state. The upper hook 4 can be rotated by the rotating shaft 6. The side of the connecting ring 7 is connected to a spring and is connected to the stoplog gates 1 through the spring. When the two stoplog gates 1 are connected, the upper stoplog gate 1 is pressed down, and the upper hook 4 is rotated toward the middle of the stoplog gate 1 by the first inclined surface 10 until it hooks the bottom hook 5. When the stopgate 1 is disconnected after use, it is necessary to lift the stopgate 1 and place it vertically on the ground so that the upper hook 4 and the bottom hook 5 are in a relaxed state, and then pull down the handle 8, and then lift the upper stopgate 1 to complete the disassembly of the lowest stopgate 1, and so on. The remaining stopgates 1 can be removed, which is convenient for lifting the stopgate 1 after maintenance, ensuring that all the stopgates 1 can be lifted after maintenance, preventing the lower stopgates 1 from being unable to lift, and improving the efficiency of maintenance work. At the same time, the self-locking of the stopgate 1 can be manually released after it is lifted, and multiple stopgates 1 can be connected as needed, which improves the convenience of operation.

[0021] The working principle of this embodiment is as follows: when in use, the connection of the two stoplog gates 1 is first positioned by the guide cone 2 and the guide sleeve 3. When the two stoplog gates 1 are connected, the upper stoplog gate 1 is pressed down, and the upper hook 4 is rotated toward the middle of the stoplog gate 1 through the first inclined surface 10 until it hooks the bottom hook 5, thereby completing self-locking. When the stoplog gates 1 are disconnected after use, the stoplog gates 1 need to be lifted and placed vertically on the ground so that the upper hook 4 and the bottom hook 5 are in a relaxed state, and then the handle 8 is pulled down, and then the upper stoplog gate 1 is lifted again to complete the removal of the lowermost stoplog gate 1, and the remaining stoplog gates 1 are removed in this way.

[0022] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
