Description

Technical Field

[0001] This utility model relates to the field of locking device technology, and in particular to a locking mechanism for engineering machinery. Background Technology

[0002] In the widespread application of modern engineering machinery, various types of equipment often need to maintain the relative stability of specific components under different working conditions to ensure the accuracy and safety of operations. For example, during the extension and retraction adjustment of the boom of a large crane, or when the angle of the excavator boom changes, the relevant connecting components must be able to reliably lock and unlock.

[0003] Traditional locking mechanisms often have several shortcomings. Many locking devices can only achieve simple fixed locking and cannot quickly and flexibly adjust the locking position according to actual operational needs. This makes it difficult for construction machinery to accurately adapt to complex and changing working conditions, affecting operational efficiency. For example, in excavation operations that require frequent fine-tuning of the boom angle, if the locking mechanism cannot respond promptly and accurately lock the new position, it will cause deviations in the excavation action and reduce the quality of excavation. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a locking mechanism for engineering machinery.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0006] A locking mechanism for engineering machinery includes a base plate, an mounting plate slidably mounted on the upper end of the base plate, a groove formed on the upper end of the mounting plate, a moving mechanism disposed inside the groove, a side plate fixedly mounted on one side of the upper end of the base plate, and a locking mechanism disposed between the side plate and the mounting plate.

[0007] Preferably, the moving mechanism includes a telescopic rod fixedly mounted on the upper end of the mounting plate, one end of which extends into the interior of the groove and is fixedly mounted with a locking pin.

[0008] Preferably, the locking mechanism includes a strip groove formed inside the side plate, and multiple locking teeth are fixedly installed at equal intervals inside the strip groove.

[0009] Preferably, a groove is provided on one side of the mounting plate, a slide rod is slidably installed inside the groove, and a locking plate is fixedly installed at one end of the slide rod. The locking plate can be adapted to be locked between multiple locking teeth.

[0010] Preferably, the other end of the slide rod extends into the interior of the groove and is fixedly mounted with a rectangular plate. The interior of the rectangular plate has an inclined groove, and the locking pin can be adapted to be inserted into the interior of the inclined groove. The telescopic rod drives the locking pin to move inside the inclined groove, thereby dragging the rectangular plate and the slide rod to move, so as to engage or disengage the locking plate between multiple locking teeth.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. By using multiple equally spaced locking teeth in the side plate of the locking mechanism and a locking plate that can be matched and locked in, the position of the mounting plate relative to the side plate can be accurately locked, ensuring that the relevant components of the engineering machinery can maintain an accurate and stable working position during operation, effectively improving the accuracy of the operation.

[0013] 2. The telescopic rod in the moving mechanism is telescopic, which can drive the locking pin to move in the inclined groove of the rectangular plate, thereby dragging the slide rod to make the locking plate engage or disengage between multiple locking teeth. This design allows the locking state between the mounting plate and the side plate to be flexibly switched, making it easy to quickly adjust the relative position of relevant components according to different working conditions, thus enhancing the overall adaptability of the mechanism.

[0014] 3. As the basic support component of the entire locking mechanism, the base plate provides a stable bearing platform for other components such as the mounting plate and side plates, ensuring that each component remains stable during operation. This helps to improve the overall stability of the construction machinery and reduce the risk of failure caused by factors such as component shaking. Attached Figure Description

[0022] Reference Figure 1-3 A locking mechanism for engineering machinery includes a base plate 1, which serves as the fundamental support component of the entire mechanism, providing a stable platform for the installation and operation of other components. A mounting plate 5 is slidably mounted on the upper end of the base plate 1. This sliding mounting allows the mounting plate 5 to move flexibly relative to the base plate 1, thus meeting the needs of different working conditions. A groove is formed at the upper end of the mounting plate 5, providing specific space for the subsequent installation and movement of related components.

[0023] A moving mechanism is installed inside the groove, and the construction of this moving mechanism is particularly crucial. Specifically, the moving mechanism includes a telescopic rod 6 fixedly installed on the upper end of the mounting plate 5. The telescopic rod 6 has the characteristic of being telescopic, and its length can be changed within a certain range. One end of the telescopic rod 6 extends into the interior of the groove and is fixedly installed with a locking pin 12. The locking pin 12 plays an important connecting and pushing role in the transmission process of the entire moving mechanism.

[0024] Meanwhile, a side plate 2 is fixedly installed on one side of the upper end of the base plate 1. The side plate 2 provides stable support and boundary definition for one side of the entire locking mechanism. A locking mechanism is provided between the side plate 2 and the mounting plate 5. The presence of the locking mechanism can effectively lock and unlock the position of the mounting plate 5 relative to the side plate 2, ensuring that the relative positions of the components of the construction machinery remain stable under specific working conditions.

[0025] Furthermore, the locking mechanism includes a strip groove 3 formed inside the side plate 2, and multiple locking teeth 4 are fixedly installed at equal intervals inside the strip groove 3. The equal-interval arrangement of these locking teeth 4 allows for relatively precise adjustment of the locking position to adapt to different working requirements.

[0026] In addition, a groove 7 is provided on one side of the mounting plate 5, and a slide rod 8 is slidably installed inside the groove 7, allowing the slide rod 8 to slide smoothly within the groove 7. A locking plate 9 is fixedly installed at one end of the slide rod 8. The shape and size of the locking plate 9 are carefully designed to fit between multiple locking teeth 4, thereby achieving a locking state between the mounting plate 5 and the side plate 2.

[0027] Furthermore, the other end of the slide rod 8 extends into the interior of the groove and is fixedly mounted with a rectangular plate 10, which provides a relatively large working surface for subsequent transmission connections. The rectangular plate 10 has an inclined groove 11 inside, and the locking pin 12 can be fitted into the inclined groove 11. The telescopic rod 6 drives the locking pin 12 to move within the inclined groove 11. Due to the special inclined surface structure of the inclined groove 11, the movement of the locking pin 12 is converted into a dragging action on the rectangular plate 10, which in turn drags the slide rod 8, ultimately enabling the locking plate 9 to be engaged or disengaged between multiple locking teeth 4. This allows for flexible control of the locking state between the mounting plate 5 and the side plate 2, meeting the needs of engineering machinery in different operational stages.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
