Description

Technical Field

[0001] The utility model relates to the technical field of clamping mechanisms, and in particular to a hydraulic clamping mechanism. Background Art

[0002] With the rapid expansion of cities in my country and the dramatic increase in urban population, the problem of urban domestic waste has directly affected the quality of citizens' living and working environment. At present, the garbage compactor is the main process equipment in the transfer station, which is used to compress and load garbage, and the garbage bin is used in conjunction with it. Through the overall loading and unloading method of the claw locking mechanism, it can be locked and separated from the split station.

[0003] The existing clamping mechanism needs to apply a large clamping force to the hook arm to ensure the braking effect on the box body. In order to ensure the clamping force, the existing clamping mechanism structure usually uses thin-walled parts to deform due to fluid pressure to produce interference fit to achieve clamping. During the entire use of the garbage compactor, mechanical vibration will occur, resulting in the inability to lock the hook, resulting in left-right imbalance, and even decoupling in severe cases.

[0004] Therefore, a hydraulic clamping mechanism is provided to solve the above problems. Utility Model Content

[0005] The utility model provides a hydraulic clamping mechanism, which solves the problem in the related art that mechanical vibration will be generated during the use of the garbage compactor, resulting in the inability to lock the clamping hook, left-right imbalance, and even decoupling in severe cases.

[0006] The technical solution of the utility model is as follows: it includes a garbage compressor, characterized in that: a garbage transfer box is provided at one end of the garbage compressor, and symmetrical clamping mechanisms are provided on both sides of one end of the garbage compressor close to the garbage transfer box, and the garbage compressor fastens the garbage transfer box through the two clamping mechanisms;

[0007] The clamping mechanism includes a fixed mounting plate, an oil cylinder, a symmetrical upper and lower fixed plates, a fixed shaft, an active arm, a driven arm, a movable shaft one, a movable shaft two and a clamping hook, wherein the fixed mounting plate, the upper and lower fixed plates are all fixedly mounted on the side wall of the garbage compressor, one end of the fixed mounting plate is hinged to the oil cylinder, the telescopic rod of the oil cylinder is hinged to one end of the active arm, the two ends of the fixed shaft are respectively fixedly connected to the upper and lower fixed plates, the middle part of the active arm is rotatably connected with a fixed shaft, the other end of the active arm is hinged to one end of the driven arm, the other end of the driven arm is hinged to the clamping hook through the movable shaft one, the movable shaft one and the movable shaft two both penetrate and are fixedly mounted on the clamping hook, the upper and lower fixed plates are both provided with sliding grooves, and the two ends of the movable shaft one and the movable shaft two respectively pass through the corresponding sliding grooves and are slidably connected thereto.

[0008] As a preferred technical solution of the utility model, a shell plate is fixedly mounted on the upper surface of the upper fixing plate.

[0009] As a preferred technical solution of the utility model, one end of the holding hook is in a right-angle L-shape, and a hook pad is provided on the inner side of one end of the holding hook.

[0010] As a preferred technical solution of the present utility model, the slide groove is in an obtuse L-shape.

[0011] The working principle and beneficial effects of the utility model are:

[0012] When in use, the oil cylinder is in its original state. When the telescopic rod of the oil cylinder is extended, the telescopic rod of the oil cylinder pushes one end of the active arm, driving the active arm to rotate on the fixed axis, and the other end of the active arm pulls back the driven arm, so that the driven arm moves toward the end close to the oil cylinder, thereby driving the movable shaft to slide in the slide groove to the end close to the oil cylinder. At this time, the hook holds the garbage transfer box tightly. Through the setting of the hook pad, when holding the garbage transfer box tightly, the hook pad can be buffered to avoid damage. If the external force wants to open the hook, it will definitely move the driven arm toward the end close to the hook. If the driven arm wants to move, the active arm needs to move. At this time, one end of the active arm has been supported by the telescopic rod of the oil cylinder and cannot move. Therefore, once locked, it cannot be opened by external force. Similarly, when the telescopic rod of the oil cylinder is retracted, the hook opens. The garbage transfer box is held tightly by the right-angle L-shaped design at one end of the hook, which can ensure accurate, safe and reliable docking. Even if the garbage compressor generates mechanical vibration during use, there will be no left-right imbalance and unhooking phenomenon. The cylinder can realize the release and locking bidirectional movement. BRIEF DESCRIPTION OF THE DRAWINGS

The garbage compressor 1 fastens the garbage transfer box 2 through two clamping mechanisms 3 to ensure that the garbage transfer box 2 and the garbage compressor 1 are accurately, safely and firmly docked without being unhooked. The clamping mechanism 3 includes a fixed mounting plate 301, an oil cylinder 302, a symmetrical upper fixed plate 303 and a lower fixed plate 304, a fixed shaft 305, and an active arm 306. 6. The driven arm 307, the movable shaft 1 308, the movable shaft 2 309 and the hook 310, the fixed mounting plate 301, the upper fixed plate 303 and the lower fixed plate 304 are all fixedly mounted on the side wall of the garbage compactor 1, one end of the fixed mounting plate 301 is hinged to the oil cylinder 302, the telescopic rod of the oil cylinder 302 is hinged to one end of the active arm 306, the oil cylinder 302 pushes the telescopic rod to drive the active arm 306 to move, and the two ends of the fixed shaft 305 are respectively fixedly connected to the upper fixed plate 303 and the lower fixed plate 304, and the middle part of the active arm 306 is rotated and connected A fixed shaft 305 is connected. When the telescopic rod of the oil cylinder 302 pushes the active arm 306 to move, the active arm 306 will rotate with the fixed shaft 305 as the axis. The other end of the active arm 306 is hinged to one end of the driven arm 307. When the active arm 306 rotates, one end of the driven arm 307 will drive the driven arm 307 to move. The other end of the driven arm 307 is hinged to the hook 310 through the movable shaft 1 308. The movable shaft 1 308 and the movable shaft 2 309 are both penetrated and fixedly installed on the hook 310. The upper fixed plate 303 and the lower fixed plate 304 are both provided with The slide groove 311 is in an obtuse L-shape, and the two ends of the movable shaft 1 308 and the movable shaft 2 309 pass through the corresponding slide groove 311 respectively and are slidably connected therewith, that is to say, the two ends of the movable shaft 1 308 and the movable shaft 2 309 always slide within the two sides of the obtuse L-shape of the slide groove 311. The purpose of setting it to an obtuse L-shape is to drive the hook 310 to move and create an angle, that is to say, the hook 310 can be opened outward, which is convenient for the garbage transfer box 2 to dock with the garbage compressor 1, ensuring the movement direction and movement distance, and making the docking more accurate, safe and reliable.

[0023] The upper surface of the upper fixing plate 303 is fixedly mounted with a shell plate 4, and the setting of the shell plate 4 ensures the safety during movement.

[0024] One end of the holding hook 310 is in a right-angle L-shape, and a hook pad 5 is provided on the inner side of one end of the holding hook 310 . The hook pad 5 can provide a buffer when the garbage transfer box 2 is tightly held.

At this time, the holding hook 310 holds the garbage transfer box 2 tightly, and the setting of the hook pad 5 When holding the garbage transfer box 2 tightly, the hook pad 5 can be used for buffering to avoid damage. If an external force wants to open the holding hook 310, the driven arm 307 will definitely move toward one end close to the holding hook 310. If the driven arm 307 wants to move, the active arm 306 needs to move. At this time, one end of the active arm 306 has been supported by the telescopic rod of the oil cylinder 302 and cannot move. Therefore, once locked, it cannot be opened by external force. Similarly, when the telescopic rod of the oil cylinder 302 is retracted, the holding hook 310 is opened. The garbage transfer box 2 is held tightly by the right-angle L-shaped design of one end of the holding hook 310, which can ensure accurate, safe and reliable docking. Even if the garbage compactor 1 generates mechanical vibration during use, there will be no left-right imbalance and unhooking phenomenon. The oil cylinder 302 can realize the release and locking bidirectional movement.

[0026] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
