Description

Technical Field

[0001] This utility model relates to the field of gearbox support seats, specifically a gearbox support seat that is easy to adjust. Background Technology

[0002] Existing automatic transmission (AT) support structures typically employ a worm gear drive mechanism to drive a clamping plate to hold the transmission body. This design aims to prevent the transmission from erratic jumping during vehicle bumps or impacts by providing strong clamping force, thereby ensuring its stability and transmission efficiency.

[0003] However, existing technologies still have some shortcomings. When vehicles operate for extended periods in harsh environments with high intensity and vibration, such as mines, continuous vibration and impact forces repeatedly act on the supporting structure. Although worm gear transmission mechanisms can provide initial clamping force, due to their structural characteristics, prolonged vibration can cause the accumulation of tiny gaps in the transmission system, resulting in a gradual weakening of the clamping force. Furthermore, fixing screws may loosen during severe vibrations.

[0004] When the clamping or fixing force weakens, the relative displacement between the gearbox body and the supporting structure will increase, making it unable to effectively resist continuous impacts and high-frequency vibrations. This may cause slight shaking of the gearbox body, which will affect the accuracy and reliability of the transmission system in the long run. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model aims to provide an easily adjustable gearbox support seat, thereby solving the problem that in existing technologies, the worm gear support structure weakens its clamping force and becomes loose due to vibration under long-term high-intensity vibration, which in turn causes gearbox shaking and affects the long-term stability and reliability of the system.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An easily adjustable gearbox support includes a fixed base body, a gearbox body connected below the fixed base body, and the gearbox body having an annular protrusion and a locking cavity facing the fixed base body.

[0008] The fixed base is provided with a first locking component and a second locking component; both the first locking component and the second locking component are slidably disposed on the fixed base.

[0009] The first locking component includes a main gripper and a secondary gripper spaced apart, and the annular protrusion is located between the main gripper and the secondary gripper.

[0010] The second locking assembly includes two symmetrical and rotatable downward pressing links. One end of each downward pressing link is provided with a synchronous gear, which meshes with each other. The other end of each downward pressing link is hinged to a transmission link. A locking block is also provided, which is correspondingly provided with the locking cavity and is hinged to the transmission link. One end of the transmission link is fixedly provided with a transverse gear, and a locking rack is slidably provided in the locking block, which meshes with the transverse gear.

[0011] As a further optimization of this utility model:

[0012] Preferably, a linkage is connected between the main gripper and the pressing link to achieve synchronous or sequential operation of the first locking component and the second locking component, simplifying operation.

[0013] Preferably, the locking cavity has a limiting groove for accommodating the locking rack, which is used to precisely guide and stabilize the locking rack, thereby enhancing the reliability of the locking.

[0014] Preferably, the main gripper includes a housing, with a moving rod and a guide rod hinged to the housing, and a clamping gear fixed to one end of the moving rod; it also includes a clamping block, with the guide rod hinged to both the moving rod and the guide rod. This structure can efficiently convert rotational motion into translational clamping action.

[0015] Preferably, the number of the first locking components on the fixed base is two sets, symmetrically arranged on both sides of the gearbox body, to provide a more balanced and stable clamping force.

[0016] Compared with the prior art, the present invention has the following significant advantages:

[0017] 1. Dual locking for robust structure: This invention uses a first locking component to laterally clamp the annular protrusion of the gearbox body, and a second locking component with a locking rack extending into the locking cavity for longitudinal locking. This dual locking method, combining lateral and longitudinal locking, effectively resists impacts and vibrations from multiple directions, greatly improving the stability of the gearbox.

[0024] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0025] It will be understood by those skilled in the art that certain well-known structures and their descriptions may be omitted in the accompanying drawings. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0026] Please see Figures 1 to 3 This utility model provides an easily adjustable gearbox support. It mainly includes a fixed base 1 and a gearbox body 2 installed below it. To achieve fixation, the gearbox body 2 is integrally formed or additionally provided with annular protrusions 3, and a locking cavity 4 is formed on its top facing the fixed base 1.

[0027] At least one set of first locking components 5 and second locking components 6 are slidably mounted on the fixed base 1. Preferably, there are two sets of first locking components 5, symmetrically arranged on the fixed base 1, to provide more stable support for the gearbox body 2.

[0028] The first locking component 5 is primarily responsible for lateral clamping and positioning. It includes a main gripper 7 and a secondary gripper 8. During installation, the annular protrusion 3 of the gearbox body 2 is positioned between the main gripper 7 and the secondary gripper 8. As shown in the specific embodiment, the main gripper 7 can be internally designed with a transmission mechanism driven by a clamping motor. For example, the clamping motor drives a clamping gear 20, which, through a linkage mechanism composed of a moving rod 18 and a guide rod 19, drives the clamping block 21 to swing, thereby causing the main gripper 7 and the secondary gripper 8 to move towards or away from each other, thus clamping or releasing the annular protrusion 3. This motor-driven method allows for precise control of the clamping force.

[0029] The second locking assembly 6 is primarily responsible for longitudinal locking, preventing the gearbox body 2 from bouncing up and down. It includes two symmetrically arranged downward pressing links 9, which can rotate around their respective pivot points. At one end of each link, there are meshing synchronizing gears 10. This design ensures that when one downward pressing link 9 rotates, the other will rotate symmetrically at the same angle.

[0030] At the other end of each downward connecting rod 9, a transmission connecting rod 11 is hinged via a pin. The other end of the transmission connecting rod 11 is hinged to a locking block 12. The position of the locking block 12 corresponds to the locking cavity 4 on the gearbox body 2. At the end of the transmission connecting rod 11, a transverse gear 13 is fixedly installed. A groove is formed inside the locking block 12, within which a locking rack 14 can slide. This locking rack 14 meshes precisely with the transverse gear 13.

[0031] The workflow is as follows:

[0032] Initial positioning: Place the gearbox body 2 under the fixed base 1, so that the annular protrusion 3 is positioned between the main jaw 7 and the secondary jaw 8 of the first locking assembly 5, and at the same time align the locking cavity 4 with the locking block 12 of the second locking assembly 6. Since the assemblies are slidable, this process is very convenient.

[0033] Lateral clamping: The first locking component 5 is activated. The main jaw 7 and the secondary jaw 8 move towards each other, tightly clamping the annular protrusion 3, completing the initial lateral fixation.

[0034] Longitudinal locking: Drive the second locking assembly 6. A force can be applied to one of the downward linkages 9 to rotate it (manually, hydraulically, or electrically). Due to the meshing of the synchronizing gears 10, both downward linkages 9 will rotate downward synchronously and symmetrically.

[0035] The rotation of the downward pressing link 9 will drive the transmission link 11 to move, causing the locking block 12 to move downward as a whole and press against the opening of the locking cavity 4.

[0036] At the same time, the movement of the transmission link 11 will cause the transverse gear 13 at its end to rotate.

[0037] The rotating transverse gear 13 drives the locking rack 14 that meshes with it, causing the locking rack 14 to extend out of the locking block 12 and be precisely inserted into the limiting groove 16 inside the locking cavity 4.

[0038] Through the above steps, the gearbox body 2 is not only firmly clamped laterally, but also rigidly locked to the fixed seat 1 by the longitudinally extending locking rack 14. The meshing of the gear and rack provides a very reliable locking effect, which can effectively resist continuous high-intensity vibrations under harsh working conditions such as mining, ensuring long-term fixed stability.

[0039] In another embodiment, a linkage 15 can be provided between the main gripper 7 and the pressing link 9. The linkage 15 can be designed to synchronously drive the pressing link 9 to rotate when the main gripper 7 clamps, thereby realizing the automated linkage of the two locking steps and further simplifying the operation.

[0040] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
