Description

Technical Field

[0001] This application relates to the field of small transport machinery technology, specifically to an auxiliary trolley for changing grinding wheels on a gear grinding machine. Background Technology

[0002] With the advancement of industrial manufacturing technology, gear grinding machines, as crucial equipment in gear processing, have seen grinding wheel replacement efficiency and safety become key factors affecting production. Since the total weight of the grinding wheel with the mandrel can reach 30KG, traditional manual handling methods place high demands on the operator's physical strength and pose significant safety risks when installing the grinding wheel inside the equipment at a height of 1000mm-1300mm. This can easily cause injury to both personnel and the grinding wheel, typically requiring two people to work together to complete the task.

[0003] Furthermore, while using specialized lifting tools to assist in handling can reduce the workload to some extent, it requires placing these tools near each piece of equipment, significantly increasing the floor space required and limiting the flexibility of equipment layout. Neither of the above two solutions effectively balances the needs for ease of operation, safety, and space utilization, necessitating a more optimized solution to improve the efficiency and safety of grinding wheel replacement. Utility Model Content

[0004] This utility model provides an auxiliary trolley for changing grinding wheels on a gear grinding machine, which solves one of the problems in the prior art, such as inconvenient operation, high safety risks, and large equipment footprint, during the handling and installation of grinding wheels with mandrels.

[0005] According to one aspect of the present invention, a grinding wheel changing auxiliary trolley for a gear grinding machine is provided, comprising: The lifting platform includes a base, a connecting mechanism, and a base. The base and base are height-adjustable via the connecting mechanism. The base is equipped with multiple casters for flexible movement of the platform. The connecting mechanism is equipped with a foot pedal, which the operator uses to control the height of the lifting platform. An auxiliary component is provided on the lifting platform. The auxiliary component includes a support frame, on which front and rear limiting units are provided, and on which rotation limiting units are provided. The lifting platform is used to adjust the horizontal height of the auxiliary components, which are used to assist in transporting the grinding wheel of the gear grinding machine.

[0006] In a further preferred embodiment, the front and rear limiting unit includes a guide rail platform with at least two guide rails. At least two sliders are slidably connected to the guide rails, and a front and rear limiting platform is provided between the sliders. The front and rear limiting platform can slide along a straight line on the guide rail platform to adjust its front and rear position. The rotation limiting unit is located on the front and rear limiting platform.

[0007] In a further preferred embodiment, the front and rear limiting platforms are provided with at least one limiting part, the limiting part including a limiting block and a limiting rod, the limiting block being located on one side of the front and rear limiting platforms, and the limiting rod being connected to the limiting block by a thread to limit the range of movement of the grinding wheel in the front and rear directions.

[0008] In a further preferred embodiment, the rotation limiting unit includes a rotating disk, which is mounted on the front and rear limiting platforms via bearings, enabling it to rotate freely 360°. The rotating disk is equipped with a rotation limiting platform, and the rotating limiting platform has a rotating bracket for supporting the grinding wheel.

[0009] In a further preferred embodiment, the rotary limiting platform is provided with at least one limiting rod two, which is threadedly connected to the rotary limiting platform to limit the range of movement of the grinding wheel in the radial direction.

[0010] In a further preferred embodiment, the rotating bracket is provided with multiple limiting recesses for supporting the mandrel of the grinding wheel.

[0011] In a further preferred embodiment, the limiting recess is provided with a flexible element, which is used to reduce the hard contact between the grinding wheel and the rotating bracket and prevent damage to the surface of the grinding wheel.

[0012] In a further preferred embodiment, the lifting platform is equipped with a fall protection limiting unit, which has a handle for easy manual operation by the operator.

[0013] In a further preferred embodiment, the lifting platform is equipped with an auxiliary pushing component, which is located outside the fall protection limiting unit, making it convenient for operators to push the trolley to move.

[0014] In practical application, the operator first releases the rotation limit unit, connects the auxiliary trolley to the grinding wheel installation workstation, unloads the assembled grinding wheel with mandrel from the workstation, and places it on the rotating bracket. Then, the operator pushes the auxiliary trolley to transport the grinding wheel to the vicinity of the gear grinding machine. After docking with the equipment, the operator raises the lifting platform to a suitable height by stepping on the foot pedal, while simultaneously opening the anti-fall limit unit to ensure platform stability. Next, the operator unlocks the front and rear limit units and pushes the grinding wheel along the guide rail platform to its installation position inside the equipment, then locks the front and rear limit units again to fix the grinding wheel's position. Finally, the lifting platform is slowly lowered, allowing the grinding wheel to be placed smoothly in the designated position. After completing the installation, the trolley is removed.

[0015] This invention, through its structural design, solves the operational difficulties and safety hazards caused by the excessive weight of grinding wheels in traditional manual handling methods, while also avoiding the space-consuming drawbacks of dedicated lifting tools. Using the auxiliary trolley provided by this invention, operators can complete handling and installation tasks without direct contact with the grinding wheel, significantly reducing labor intensity and safety risks. Furthermore, the trolley has a compact structure, small footprint, and is suitable for various equipment layout scenarios, exhibiting high flexibility and applicability.

[0016] The technical effect of this utility model comes from the synergistic effect between its components.

Detailed Implementation

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] Please see Figures 1-4 This utility model provides an auxiliary trolley for changing grinding wheels on a gear grinding machine, the overall structure of which is as follows: Figure 1 and Figure 2 As shown, the system includes a lifting platform 1, auxiliary components 2, front and rear limit units, a rotation limit unit, and a fall protection limit unit. The lifting platform 1 consists of a base, a connecting mechanism, and a base. The base and base are connected by a connecting mechanism for height adjustment. A foot pedal is provided on the connecting mechanism, allowing the operator to control the height of the lifting platform 1 by stepping on the foot pedal. Multiple casters are installed at the bottom of the base for flexible movement of the trolley. A support frame 21 is fixed on the base, and the auxiliary components 2 are mounted on the support frame 21 for positioning and transporting the grinding wheel.

[0025] The front and rear limit units are mounted on auxiliary component 2, and their specific structure is as follows: Figure 3 As shown, the system includes a guide rail platform 31, sliders 32, and front and rear limiting platforms 33. The guide rail platform 31 has at least two parallel guide rails, and two sliders 32 are slidably connected to each guide rail. The sliders 32 are fixedly connected to the front and rear limiting platforms 33 by bolts. The front and rear limiting platforms 33 can slide along a straight line on the guide rail platform 31, thereby adjusting their front and rear positions. The front and rear limiting platforms 33 have at least one limiting part 34, which consists of a limiting block and a limiting rod. The limiting block is fixed to one side of the front and rear limiting platforms 33, and the limiting rod is connected to the limiting block by threads, used to limit the range of movement of the front and rear limiting platforms 33 in the front and rear direction.

[0026] The rotation limiting unit is mounted on the front and rear limiting platforms 33, and its specific structure is as follows: Figure 4As shown, the system includes a rotating disk 41, a rotating limiting platform 42, and a rotating bracket 43. The rotating disk 41 is connected to the front and rear limiting platforms 33 via bearings, enabling it to rotate freely 360°. The rotating limiting platform 42 is fixed to the upper surface of the rotating disk 41. The rotating limiting platform 42 is provided with at least one limiting rod 44, which is connected to the rotating limiting platform 42 via threads to limit the rotation range of the rotating limiting platform 42. The rotating bracket 43 is fixed to the rotating limiting platform 42 and is used to support the grinding wheel. The rotating bracket 43 is provided with multiple limiting recesses to support the mandrel of the grinding wheel. Flexible elements 45, made of rubber, are embedded in the limiting recesses to reduce hard contact between the grinding wheel and the rotating bracket 43 and prevent damage to the surface of the grinding wheel.

[0027] Both the fall arrestor unit 5 and the auxiliary push assembly 6 are mounted on the lifting platform 1, and their specific structures are as follows: Figure 1 and Figure 2 As shown. The handle is fixed to the outside of the fall arrestor unit for easy manual operation by the operator. The fall arrestor unit is used to prevent the grinding wheel from falling. The auxiliary push assembly 6 facilitates the operator to move the trolley.

[0028] In practical applications, the operator first releases the limiting rod 44 in the rotation limiting unit and unlocks the rotation limiting platform 42, allowing the rotating bracket 43 to rotate freely. Then, the auxiliary trolley is connected to the grinding wheel mounting workstation, and the assembled grinding wheel with mandrel is unloaded from the workstation and placed on the rotating bracket 43. The limiting recess of the rotating bracket 43 fits tightly against the grinding wheel mandrel, ensuring that the grinding wheel will not shift during transport. Next, the operator pushes the auxiliary trolley to transport the grinding wheel to the vicinity of the gear grinding machine. During this process, the flexible steering function of the casters allows the trolley to easily navigate through narrow spaces.

[0029] After docking with the equipment, the operator raises the lifting platform 1 to a suitable height by stepping on the foot pedal, and simultaneously activates the fall arrestor to ensure platform stability. Next, the operator unlocks the limit levers in the front and rear limit units and pushes the grinding wheel along the guide rail platform 31 to its installation position inside the equipment, then locks the front and rear limit units again to fix the grinding wheel's position. Finally, the lifting platform 1 is slowly lowered so that the grinding wheel is placed stably in the designated position, and the trolley is removed after the installation is complete.

[0030] During the above operations, the coordinated action of each component ensures the safety and efficiency of the grinding wheel replacement operation. The lifting platform 1, with its foot pedal for height adjustment, provides a basis for precise grinding wheel positioning. The front and rear limit units, through the cooperation of the slider 32 and the limit part 34, ensure the stability of the grinding wheel in the front-rear direction. The rotation limit unit, through the design of the rotating disc 41 and the limit rod 44, achieves precise control of the grinding wheel in the radial direction. The anti-fall limit unit prevents the grinding wheel from accidentally falling, ensuring the safety of the operation. The auxiliary push assembly enhances the ease of movement of the trolley.

[0031] To enable those skilled in the art to fully understand and implement this utility model, the specific implementation principle of this utility model is further explained below in conjunction with a specific application scenario.

[0032] First, the operator moves the auxiliary trolley to the vicinity of the grinding wheel installation workstation, ensuring that the swivel casters can flexibly adjust the trolley's position. At this time, the lifting platform 1 is at its initial height, facilitating subsequent operations. The operator releases the limit rod 44 in the rotation limit unit and unlocks the rotation limit platform 42, allowing the rotating bracket 43 to rotate freely. Subsequently, the operator removes the assembled grinding wheel with mandrel from the workstation and places it on the rotating bracket 43. The limiting recess on the rotating bracket 43 fits tightly against the grinding wheel mandrel, and the flexible component 45 is embedded in the limiting recess. The flexible properties of the rubber material reduce the hard contact between the grinding wheel and the bracket, thereby preventing damage to the grinding wheel surface.

[0033] Next, the operator pushes the auxiliary trolley to transport the grinding wheel to the vicinity of the gear grinding machine. During this process, the flexible steering function of the casters allows the trolley to easily navigate narrow spaces, while the sturdy structure of the base and support frame 21 ensures the safety of the grinding wheel during transportation. Upon reaching the vicinity of the equipment, the operator steps on the foot pedal and adjusts the height of the lifting platform 1 through the connecting mechanism, gradually raising it to a height that matches the equipment's installation position.

[0034] Subsequently, the operator unlocks the first limit rod in the front and rear limit units and pushes the grinding wheel along the guide rail platform 31 to its installation position inside the equipment. During this process, the slider 32 slides on the guide rail platform 31, driving the front and rear limit platforms 33 to move in a straight line, thereby adjusting the front and rear position of the grinding wheel. The first limit rod is connected to the limit block by threads to ensure the stability of the grinding wheel in the front and rear direction. After the grinding wheel is pushed to the designated position, the operator locks the front and rear limit units again to fix the position of the grinding wheel. In this step, the front and rear limit units achieve precise control of the grinding wheel in the front and rear direction through the cooperation of the slider 32 and the limit part 34.

[0035] Finally, the operator slowly lowers the lifting platform 1, ensuring the grinding wheel is stably positioned in the designated location inside the equipment. During this process, the height of the lifting platform 1 is adjusted via a foot pedal, allowing the operator to gradually adjust the height as needed to ensure precise positioning of the grinding wheel. After installation, the operator pushes the auxiliary trolley out of the equipment area.

[0036] During the above operations, the coordinated action of the various components ensures the safety and efficiency of the grinding wheel replacement operation. The lifting platform 1 achieves height adjustment through the foot pedal, providing a basis for the precise positioning of the grinding wheel; the front and rear limit units, through the cooperation of the slider 32 and the limit part 34, ensure the stability of the grinding wheel in the front and rear directions; the rotation limit unit, through the design of the rotating disk 41 and the limit rod 44, achieves precise control of the grinding wheel in the radial direction.

[0037] In summary, this utility model effectively solves the operational difficulties and safety hazards caused by the excessive weight of the grinding wheel in traditional manual handling methods through the synergistic effect of its components. It also avoids the drawback of special lifting tools occupying space, providing an efficient, safe and economical solution for grinding wheel replacement operations on gear grinding machines.
