Description

Technical Field

[0001] The utility model relates to the field of lifting platforms, in particular to a mobile lifting platform. Background Art

[0002] When repairing vehicles, some large assemblies need to be installed and disassembled. During this process, a mobile lifting platform is needed to move and lift the assemblies to assist workers in repairing. Traditional mobile lifting platforms include gantry cranes, cranes, and forklifts. These devices are widely used in industry and construction, but they require too many steps of manual assistance and fail to reduce the workload of workers to a large extent. Most of the current mobile lifting platforms use hydraulic drive for lifting, which makes the mobile lifting platforms too bulky and has limited flexibility and automation.

[0003] At present, most mobile lifting platforms are composed of one or more hydraulic cylinders and platforms, and use electric motors or hand cranks to provide power for necessary repairs, maintenance, and safety inspections. Since hydraulic cylinders are used to drive the platform to lift, they need to be maintained regularly, which increases costs. Utility Model Content

[0010] Among them, the first end of the first support beam of the first support arm and the first end of the second support beam are both mounted on the screw rod through a light hole, and the first end of the first support beam of the second support arm and the first end of the second support beam are both mounted on the screw rod through a threaded hole.

[0012] Furthermore, the driving component is located between the two lifting assemblies.

[0013] Furthermore, along the width direction of the mobile lifting platform, the two lifting assemblies are symmetrically arranged on opposite sides of the mobile lifting platform.

[0014] Furthermore, the movable wheels include electric universal wheels, and there are at least four electric universal wheels, and at least four of the electric universal wheels are arranged on a side of the base close to the ground.

[0015] Furthermore, the driving component includes a motor, and the mobile lifting platform also includes a controller, and the controller is electrically connected to the electric universal wheel and the motor to control the electric universal wheel and the motor to work or stop working.

First, place the predetermined assembly on the upper surface of the lifting platform, and then control the mobile lifting platform to move below the position where the predetermined assembly needs to be installed (that is, the installation position).

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0028] In order to solve the problem that the existing mobile lifting platform is too heavy and costly, according to the embodiment of the present application, a mobile lifting platform is provided. The mobile lifting platform of the present application will be described in detail below in conjunction with the accompanying drawings.

[0029] See also Figure 1 As shown, according to an embodiment of the present utility model, a mobile lifting platform is provided, which includes a base 10, a lifting assembly 20 and a lifting platform 30.

[0030] The base 10 is provided with moving wheels (not shown in the figure). The lifting assembly 20 includes at least two, at least two lifting assemblies 20 are arranged on the base 10 in parallel and at intervals, each lifting assembly 20 includes a scissor jack and at least one first lifting structure 21, the scissor jack includes a second lifting structure 22, a screw 23 and a driving component 24, the screw 23 passes through the second lifting structure 22 and at least one first lifting structure 21 in sequence, and the driving component 24 drives the screw 23 to rotate to drive the second lifting structure 22 and the first lifting structure 21 to rise and fall synchronously. The lifting platform 30 is fixedly connected to the top of the lifting assembly 20.

[0031] In the present application, when the mobile lifting platform of the present application is used for auxiliary installation work, the lifting platform 30 is at the lowest point (that is, the point when the lifting platform 30 drops to the lowest point in the height direction of the mobile lifting platform). First, the predetermined assembly (not shown in the figure) is placed on the upper surface of the lifting platform 30, and then the mobile lifting platform is controlled to move to the position below the position where the predetermined assembly needs to be installed (that is, the installation position). Then, the driving component 24 is started, and the screw 23 rotates around its own axis under the drive of the driving component 24 to drive each lifting component 20 to rise along the height direction of the mobile lifting platform. The rise of each lifting component 20 can lift the lifting platform 30. Finally, when the predetermined assembly on the lifting platform 30 is lifted to the installation position, the driving component 24 is turned off to stop the lifting platform 30 from rising, and the predetermined assembly can stay at the installation position with the lifting platform 30. At this time, the worker can perform maintenance work.

[0032] That is to say, compared with the existing mobile lifting platform, the mobile lifting platform of the present application abandons the original air cylinder or hydraulic cylinder, and can realize the lifting of the lifting platform 30 by adopting a lifting assembly 20 composed of a scissor jack and at least one first lifting structure 21. During actual work, the driving component 24 works, and the first lifting structure 21 and the second lifting structure 22 can be driven to lift and lower at the same time through a screw 23, thereby solving the problem that the mobile lifting platform is too bulky and costly.

[0033] Further, see Figure 1 As shown, the first lifting structure 21 and the second lifting structure 22 both include a first support arm 211 and a second support arm 212, and the first support arm 211 and the second support arm 212 both include a first support beam 2111 and a second support beam 2112. The first end of the first support beam 2111 is hinged to the first end of the second support beam 2112, and the second end of the first support beam 2111 and the second end of the second support beam 2112 are hinged to the bottom of the base 10 and the lifting platform 30, respectively, and the screw 23 passes through the first support arm 211 and the second support arm 212.

[0034] Among them, the first end of the first support beam 2111 of the first support arm 211 and the first end of the second support beam 2112 are both mounted on the screw rod 23 through a light hole (the light hole can be directly set on the first support beam 2111 and the second support beam 2112 of the first support arm 211, or an adapter, such as an adapter sleeve, can be set to hinge the first support beam 2111 and the second support beam 2112 of the first support arm 211 on the adapter sleeve), and the first end of the first support beam 2111 and the first end of the second support beam 2112 of the second support arm 212 are both mounted on the screw rod 23 through a threaded hole. With such arrangement, when the screw rod 23 rotates under the drive of the driving component 24, the first ends of the first support beam 2111 and the second support beam 2112 of the second support arm 212 provided with the threaded hole can be driven to reciprocate along the length direction of the screw rod 23, so that the first support beam 2111 and the second support beam 2112 of the second support arm 212 are away from the two ends of the screw rod 23 to perform a movement mode of spreading or gathering, and finally drive the lifting platform 30 to rise and fall. At the same time, the first support beam 2111 and the second support beam 2112 of the first support arm 211 can synchronously move along the length direction of the screw rod 23 during the lifting and falling process of the lifting platform 30, so that the first support arm 211 is away from the two ends of the screw rod 23 to perform a spreading or gathering movement, which can improve the lifting stability and structural stability of the entire lifting assembly 20.

[0035] For example, the lifting components 20 of the present application may be two, three or more, and the first lifting structures 21 of each lifting component 20 may be one, two or more. This embodiment shows the case where there are two lifting components 20 and the first lifting structure 21 of each lifting component 20 is one. For the convenience of description, the following description is based on the case where there are two lifting components 20 and the first lifting structure 21 of each lifting component 20 is one.

[0036] Specifically, when the mobile lifting platform of the present application is working, with respect to the second lifting structure 22, the driving component 24 drives the screw 23 to rotate clockwise around its own axis, and the first end of the first support beam 2111 of the first support arm 211 and the first end of the first support beam 2111 of the second support arm 212 can approach each other along the length direction of the screw 23 on the screw 23, at this time, the lifting platform 30 is in an ascending state. When working, the driving component 24 drives the screw 23 to rotate counterclockwise around its own axis, and the first end of the first support beam 2111 of the first support arm 211 and the first end of the first support beam 2111 of the second support arm 212 can move away from each other along the length direction of the screw 23 on the screw 23, at this time, the lifting platform 30 is in a descending state. It should be noted that the first lifting structure 21 and the second lifting structure 22 of each lifting assembly 20 of the present application are both arranged in a linkage manner, that is, they are driven by a screw rod 23, and the screw rod 23 of each lifting assembly 20 rotates clockwise or counterclockwise around its own axis to make each lifting assembly 20 rise or fall. In order to ensure the stability of the lifting platform 30 of the present application during operation, therefore, the lifting assembly 20 of the present application is at least two.

[0037] Further, see Figure 1 As shown, the second lifting structure 22 also includes a speed reduction mechanism 221 , which is disposed on the first support arm 211 of the second lifting structure 22 , the input end of the speed reduction mechanism 221 is connected to the driving component 24 , and the output end of the speed reduction mechanism 221 is connected to the screw 23 .

[0038] Specifically, a gear mechanism (not shown) is provided inside the speed reduction mechanism 221. The high-speed rotation of the driving component 24 is input to the speed reduction mechanism 221 through the input end of the speed reduction mechanism 221. When the high-speed rotation of the driving component 24 is slowed down to a speed required by the mobile lifting platform of the present application by the gear mechanism inside the speed reduction mechanism 221, the slowed speed is output to the screw 23 through the output end of the speed reduction mechanism 221 to drive each lifting assembly 20 to move up and down. In addition, the speed reduction mechanism 221 can increase the torque of the screw 23 during the deceleration process, so that each lifting assembly 20 can lift a heavier predetermined assembly.

[0039] Further, see Figure 1 As shown, the driving component 24 is located between the two lifting assemblies 20. Specifically, the driving component 24 is fixed to the first support arm 211 of the second lifting structure 22 of each lifting assembly 20. The arrangement of the driving component 24 between the two lifting assemblies 20 can reasonably utilize the space between the two lifting assemblies 20, which is conducive to reducing the size of the mobile lifting platform of the present application, thereby reducing the production cost of the mobile lifting platform of the present application.

[0040] Further, see Figure 1 As shown, along the width direction of the mobile lifting platform, two lifting assemblies 20 are symmetrically arranged on opposite sides of the mobile lifting platform.

[0041] Specifically, the width direction of the mobile lifting platform mentioned in this application, i.e. Figure 1 The two lifting assemblies 20 are symmetrically arranged on opposite sides of the mobile lifting platform to make the lifting platform 30 more stable in force and reduce the deformation of the lifting platform 30 under the same weight. Figure 1 The lifting components 20 are symmetrically arranged on opposite sides of the mobile lifting platform (in the direction indicated by x in the figure), and because the side length of the mobile lifting platform is longer in the length direction, the lifting platform 30 is more likely to bend and deform when bearing the weight of the predetermined assembly than the method of arranging the lifting component 20 along the width direction of the mobile lifting platform.

[0042] Further, see Figure 1 As shown, the moving wheels include electric universal wheels, and there are at least four electric universal wheels, and at least four electric universal wheels are arranged on the side of the base 10 close to the ground. The electric universal wheels can drive the mobile lifting platform of the present application to move and turn on the ground under the drive of electric energy. When using the mobile lifting platform of the present application for auxiliary maintenance work, the worker can control the speed and direction of the electric universal wheels to control the mobile lifting platform to move on a predetermined track at a predetermined speed, and then transport the predetermined assembly to a designated location.

[0043] Further, see Figure 1 As shown, the driving component 24 includes a motor 241, and the mobile lifting platform also includes a controller 40. The controller 40 is electrically connected to the electric universal wheel and the motor 241 to control the electric universal wheel and the motor 241 to work or stop working.

[0044] For example, when using the mobile lifting platform of the present application, the worker can control the motor 241 to rotate clockwise or counterclockwise through the controller 40, thereby controlling the rise or fall of the lifting assembly 20, so as to lift the predetermined assembly to a height suitable for installation. At the same time, the worker can also control the speed and direction of the electric universal wheel through the controller 40, thereby controlling the mobile lifting platform to move along a predetermined route to achieve the purpose of transporting the predetermined assembly to a designated location for installation.

[0045] Further, see Figure 1 As shown, the controller 40 includes a remote controller (not shown in the figure), and the electric universal wheel and the motor 241 are both provided with a receiver for receiving a control signal from the remote controller.

[0046] Specifically, when the mobile lifting platform of the present application is used for auxiliary maintenance, the worker can input the command that the mobile lifting platform needs to execute on the remote control, and the remote control can convert the command input by the worker into a control signal and send it to the receiver on the electric universal wheel and the motor 241 respectively. The receiver then converts the control signal into an electrical signal and transmits it to the electric universal wheel and the motor 241 respectively, thereby controlling the movement of the mobile lifting platform and the lifting and lowering of the lifting platform 30. Compared with the existing mobile lifting platform, the mobile lifting platform of the present application can realize remote control, which effectively improves the flexibility and automation of the mobile lifting platform.

[0047] Further, see Figure 1 As shown, along the width direction of the mobile lifting platform, grooves 11 are provided on the opposite side edges of the base 10. The grooves 11 extend along the length direction of the mobile lifting platform. The grooves 11 are provided one-to-one with the lifting components 20. The bottom ends of the lifting components 20 are respectively provided at the bottoms of the grooves 11. The grooves 11 are used to accommodate the lifting components 20 when the lifting platform 30 is at the lowest point.

[0048] Specifically, the bottom end of each lifting assembly 20 is hinged to the bottom of each groove 11, and when the lifting assembly 20 is raised or lowered, each first support beam 2111 of each lifting assembly 20 can rotate around its respective hinge, and each lifting assembly 20 is arranged in parallel, so that the lifting platform 30 can be smoothly raised or lowered. In addition, when the lifting platform 30 is lowered to the lowest point, each lifting assembly 20 can be folded and stored in each groove 11, until the upper surface of the lifting platform 30 is flush with the upper surface of the base 10, the lifting platform 30 stops lowering. Such a setting has two advantages: one is that the mobile lifting platform of the present application is more beautiful. The second is that when the mobile lifting platform of the present application is lowered to the lowest point, the height dimension of the mobile lifting platform is smaller, so that the worker can control the mobile lifting platform to reach the bottom of the predetermined assembly, and the step of transporting the predetermined assembly to the lifting platform 30 can be omitted to a certain extent.

[0049] Further, see Figure 1 As shown, a side wall of the groove 11 is provided with an avoidance notch 12 for avoiding the driving component 24 and / or the speed reduction mechanism 221 .

[0050] Optionally, the avoidance notch 12 provided on the side wall of the groove 11 of the present application can be used to avoid the driving component 24, can also be used to avoid the speed reduction mechanism 221, and can also be used to avoid the driving component 24 and the speed reduction mechanism 221 at the same time. This embodiment shows the situation where the avoidance notch 12 is used to avoid the speed reduction mechanism 221. Specifically, in this embodiment, when the lifting platform 30 descends to the lowest point, each lifting component 20 is just completely folded and stored in each groove 11, and the speed reduction mechanism 221 is also just located at the avoidance notch 12. Such a setting makes the spatial layout of each part of the mobile lifting platform of the present application more reasonable, reduces the size of the mobile lifting platform to a certain extent, and further saves costs.

[0051] It can be known from the above statements that the present application can solve the problem that the existing mobile lifting platform is too heavy and costly by setting a mobile lifting platform composed of a base 10, a lifting assembly 20, a lifting platform 30 and a controller 40. The present application replaces the hydraulic cylinder or the cylinder of the existing mobile lifting platform with the lifting assembly 20 of the present application, which can solve the problem that the mobile lifting platform is too heavy and reduce the production cost to a certain extent. In addition, the existing mobile lifting platform needs to be regularly maintained because it uses a hydraulic cylinder or a cylinder, resulting in increased costs, while the lifting assembly 20 of the present application does not need to be frequently maintained, which can save maintenance costs to a certain extent. In addition, the mobile lifting platform of the present application can control the movement and lifting of the mobile lifting platform through a remote control, and can also lift and move the predetermined assembly parts below 3 tons forward and backward, left and right, up and down. And the running distance and position of the mobile lifting platform can be accurately controlled by the remote control, and it can be accurately positioned during the installation process, and the work intensity of disassembling and assembling the predetermined assembly parts can be greatly reduced.

[0052] It can be seen that the mobile lifting platform of the present application can be remotely controlled by a remote control, which can to a certain extent prevent workers from suffering injuries such as bumps and scratches during the maintenance process. While ensuring the safety of the workers, it also reduces the labor intensity of the workers.

[0053] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0054] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only to facilitate the distinction between corresponding components. If not otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0055] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
