Description

Technical Field

[0001] This utility model relates to the field of lifting platform technology, and specifically discloses a lifting worktable for motor testing. Background Technology

[0002] An electric motor, also known as a motor, is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. Electric motors are widely used in electrical processing, industrial equipment, agricultural equipment, and transportation vehicles. Depending on the installation method, electric motors can be divided into horizontal motors, vertical motors, and vertical-horizontal motors. During the production process of electric motors, they need to be tested to ensure that they can be used normally. For the convenience of users, the motors to be tested are usually placed on a lifting platform.

[0003] Chinese patent CN210029904U discloses a motor testing lifting platform, including a base and a lifting plate. The base has an equipment cavity, a bottom plate is positioned above the base, and a protective shell is positioned above the bottom plate. The lifting plate is housed within the protective shell, and guide post holes are machined within the lifting plate. This invention uses guide posts to connect and support the bottom plate and top plate, while the protective shell protects the internal components and further supports the top plate, effectively improving the load-bearing capacity of the top plate, resulting in higher structural strength and easier installation and disassembly. The use of guide posts and guide post holes in combination... The lifting platform is guided to improve its stability, and the test platform is supported by a top rod. The lifting platform can be vertically raised and lowered along the guide column by a screw, and the lifting platform and the top rod work together to raise and lower the test platform vertically. The height adjustment efficiency is higher and the structure is more stable. However, the distance between the bottom plate and the base of the above-mentioned lifting platform is inconvenient to adjust, so the lifting platform still occupies a lot of space when it is not in use, and it is not conducive to the storage and transportation of the lifting platform itself, which is quite inconvenient. Therefore, in order to solve the above problems, this utility model proposes a lifting worktable for motor testing. Utility Model Content

[0004] The present invention aims to provide a lifting workbench for motor testing, which can be folded when not in use, reducing the distance between the base and the support mechanism, reducing the space occupied by the workbench, and facilitating the stacking, storage and transportation of the workbench itself.

[0005] This utility model is achieved through the following technical solution:

[0006] A lifting workbench for motor testing includes a base and a lifting mechanism. The lifting mechanism is located above the base, and a support mechanism is located at the upper end of the lifting mechanism. A protective plate is located above the support mechanism. The base includes a bearing plate, and two limiting holes are symmetrically arranged at both ends of the bearing plate. The lifting mechanism includes four telescopic rods, each with a first mounting seat at its telescopic end and a first connecting seat at the end of each telescopic rod away from the first mounting seat. A second mounting seat is located outside the first connecting seat, and a limiting plate is connected below the second mounting seat. The limiting plate is slidably connected to the limiting holes. The support mechanism includes a platform, with multiple first mounting holes arranged in a linear array inside the platform. Two second connecting seats are symmetrically connected at both ends of the lower part of the platform, and a reserved groove is provided on the inner side of the platform.

[0007] As a further feature of the above solution, two universal wheels are symmetrically connected to both ends of the lower part of the bearing plate to facilitate the adjustment of the position of the worktable. A first connecting hole is provided at both ends of the limiting hole, and a first connecting shaft is connected to both ends of the limiting plate. The first connecting shaft passes through the interior of the first connecting hole, and a first nut is threaded on the outer side of the first connecting shaft to limit the position of components such as the limiting plate, the second mounting base, and the telescopic rod.

[0008] As a further feature of the above solution, the first connecting seat is rotatably connected to the second mounting seat via a first bolt, and the first mounting seat is rotatably connected to the second connecting seat via a second bolt. A second nut and a third nut are threaded onto the outer sides of the first and second bolts, respectively. This allows the telescopic rod to smoothly switch between parallel and perpendicular states of the support plate by tightening and loosening the second and third nuts before and after the workbench is unfolded or folded. When the telescopic rod is adjusted to be perpendicular to the support plate and when the workbench is unfolded, the first mounting seat and the second connecting seat are fixed, preventing the first mounting seat from rotating outside the second connecting seat. This ensures the stability of the support mechanism during use. The telescopic rod is connected to a terminal device via an electrical signal, allowing the user to control the extension and retraction of the telescopic rod to adjust the ground clearance of the support mechanism.

[0009] As a further feature of the above solution, the bottom of the reserved slot is symmetrically provided with two second connecting holes, and both sides of the open end of the reserved slot are provided with second connecting shafts. The inner side of the reserved slot is provided with a first support plate, and the interior of the first support plate is provided with a plurality of first mounting holes arranged in a linear array. One end of the first support plate is provided with two insert rods, and the two insert rods respectively pass through the interior of the two second connecting holes. The outer sides of the two insert rods are threaded with fourth nuts. The two ends of the first support plate away from the insert rods are detachably connected to the two second connecting shafts, which facilitates the disassembly, assembly and maintenance of the first support plate. Horizontal motors of different sizes can be mounted on the first support plate or platform, making it convenient for users to conduct corresponding tests.

[0010] As a further feature of the above solution, a second support plate is provided on the inner side of the reserved slot. Two insert rods are symmetrically arranged at one end of the second support plate. The two ends of the second support plate away from the insert rods are detachably connected to two second connecting shafts respectively. The interior of the second support plate is provided with a reserved hole to facilitate the output shaft of the vertical motor to pass through the reserved hole. Multiple second mounting holes arranged in a circumferential array are provided on the outer side of the reserved hole to facilitate the mounting of vertical motors of different diameters on the second support plate, making it convenient for users to perform corresponding testing operations.

[0011] As a further feature of the above solution, the two ends of the protective plate are detachably connected to the two ends of the platform, which can keep the first and second mounting holes in the support mechanism clean and reduce the workload of the user in cleaning the holes.

[0012] At least one of the four omnidirectional wheels in this invention is an omnidirectional brake wheel. The four telescopic rods involved include, but are not limited to, remote-controlled telescopic rods. The terminal devices include, but are not limited to, remote controllers. The installation positions of the telescopic rod's control unit, power element, and drive element are common and conventional technologies in the field. The operation of the remote-controlled electric telescopic rod by the remote controller is also a common and conventional technology in the field, and therefore, it is not shown in the figure.

[0013] The present invention has the following beneficial effects during use:

[0014] The use of the limiting hole in the base can restrict the movement direction of the limiting plate and the second mounting base. The combination of the first connecting hole, the first connecting shaft and the first nut can fix the position of the limiting plate and the second mounting base when the limiting plate moves from one end of the limiting hole to the other end.

[0015] The combination of the first bolt, the second bolt, the second nut, and the third nut allows the second and third nuts to be loosened before and after the second mounting base position is adjusted. This ensures that the first and second mounting bases can rotate smoothly on the outside of the second and first connecting bases, respectively. This facilitates the smooth switching of the telescopic rod between parallel and perpendicular states with the bearing plate, thereby allowing the workbench to be unfolded or folded, saving space occupied by the workbench when idle. After the second mounting base position is adjusted, the second and third nuts are tightened to fix the first and second mounting bases, ensuring the stability of the support mechanism during idle or active operation.

[0016] The combination of the first support plate, the second support plate, and multiple first mounting holes and second mounting holes allows horizontal and vertical motors of different sizes to be mounted on the first support plate and the second support plate respectively, facilitating users to perform corresponding motor testing operations.

[0028] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The following will refer to the appendix... Figures 1-9 This application will be described in detail with reference to the embodiments.

[0030] An embodiment discloses a lifting workbench for motor testing, including a base 1 and a lifting mechanism 2. The lifting mechanism 2 is disposed above the base 1, and a support mechanism 3 is disposed at the upper end of the lifting mechanism 2. A protective plate 4 is disposed above the support mechanism 3. The base 1 includes a bearing plate 11, and two limiting holes 111 are symmetrically disposed at both ends of the bearing plate 11. The lifting mechanism 2 includes four telescopic rods 21, and the telescopic ends of the four telescopic rods 21 are all connected to a first mounting base 211. The four telescopic rods 21 are located away from the first mounting base 211. One end of each mounting base 211 is connected to a first connecting base 212. A second mounting base 22 is provided on the outer side of the first connecting base 212. A limiting plate 221 is connected to the lower part of the second mounting base 22. The limiting plate 221 is slidably connected to the limiting hole 111. The support mechanism 3 includes a platform 31. A plurality of first mounting holes 311 arranged in a linear array are provided inside the platform 31. Two second connecting bases 32 are symmetrically connected to the lower ends of the platform 31. A reserved groove 312 is provided on the inner side of the platform 31.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, two universal wheels 12 are symmetrically connected to both ends of the lower part of the bearing plate 11, which facilitates the adjustment of the position of the worktable. Both ends of the limiting hole 111 are provided with first connecting holes 112. Both ends of the limiting plate 221 are connected with first connecting shafts 23. The first connecting shafts 23 pass through the interior of the first connecting holes 112. The outer side of the first connecting shafts 23 is threaded with a first nut 231, which can limit the position of components such as the limiting plate 221, the second mounting base 22, and the telescopic rod 21.

[0032] like Figure 1 , Figure 3 and Figure 4 As shown, the first connecting seat 212 is rotatably connected to the second mounting seat 22 via the first bolt 24, and the first mounting seat 211 is rotatably connected to the second connecting seat 32 via the second bolt 33. The outer sides of the first bolt 24 and the second bolt 33 are respectively threaded with a second nut 241 and a third nut 331. By tightening and loosening the second nut 241 and the third nut 331 before and after the workbench is unfolded or folded, the telescopic rod 21 can be smoothly switched between the parallel and perpendicular states of the support plate 11. When the telescopic rod 21 is adjusted to be perpendicular to the support plate 11 and when the workbench is unfolded, the first mounting seat 211 and the second connecting seat 32 are fixed, preventing the first mounting seat 211 from rotating on the outside of the second connecting seat 32, so that the support mechanism 3 remains stable during use. The telescopic rod 21 is connected to the terminal equipment via an electrical signal, which allows the user to control the extension and retraction of the telescopic rod 21 to adjust the distance between the support mechanism 3 and the ground.

[0033] like Figure 1 , Figure 4 and Figure 5 As shown, the bottom of the reserved slot 312 is symmetrically provided with two second connecting holes 313. Both sides of the open end of the reserved slot 312 are provided with second connecting shafts 314. A first support plate 34 is provided inside the reserved slot 312. The interior of the first support plate 34 is provided with a plurality of first mounting holes 311 arranged in a linear array. One end of the first support plate 34 is provided with two insert rods 341, which respectively pass through the interior of the two second connecting holes 313. The outer sides of the two insert rods 341 are threaded with fourth nuts 342. The two ends of the first support plate 34 away from the insert rods 341 are detachably connected to the two second connecting shafts 314, facilitating the disassembly, assembly, and maintenance of the first support plate 34. This allows for the installation of horizontal motors of different sizes on the first support plate 34 or the platform 31, facilitating corresponding tests by the user.

[0034] like Figure 6 and Figure 8As shown, a second support plate 35 is provided on the inner side of the reserved slot 312. Two insertion rods 341 are symmetrically arranged at one end of the second support plate 35. The two ends of the second support plate 35 away from the insertion rods 341 are detachably connected to two second connecting shafts 314 respectively. A reserved hole 351 is provided inside the second support plate 35 to facilitate the output shaft of the vertical motor to pass through the reserved hole 351. A plurality of second mounting holes 352 arranged in a circumferential array are provided on the outer side of the reserved hole 351 to facilitate the installation of vertical motors of different diameters on the second support plate 35, which is convenient for users to perform corresponding testing operations.

[0035] like Figure 1 and Figure 7 As shown, the two ends of the protective plate 4 are detachably connected to the two ends of the platform 31, which can keep the first mounting hole 311 and the second mounting hole 352 in the support mechanism 3 clean and reduce the workload of the user in cleaning the above holes.

[0036] Before using the motor testing lifting platform disclosed in this embodiment, use a wrench or other tools to unscrew the first nuts 231 on the outside of the four first connecting shafts 23 and set them aside. Then, loosen the four second nuts 241 and the third nuts 331 in sequence. Pull the limiting plate 221 from the end away from the universal wheel 12 in the limiting hole 111 and straighten the end close to the limiting hole 111, so that the first connecting shaft 23 on one side of the limiting plate 221 is inserted into the first connecting hole 112 near the universal wheel 12 in the limiting hole 111. During the adjustment of the position of the limiting plate 221, the first mounting base 211 and the second mounting base 22 rotate on the outside of the first connecting base 212 and the second connecting base 32, respectively, using the first bolt 241 and the second bolt 33 as rotation axes. After adjusting the telescopic rod 21 from a state parallel to the bearing plate 11 to a vertical state, loosen the four second nuts in sequence. Tighten 241 and the third nut 331 to stabilize the first mounting base 211 and the second mounting base 22, and to keep the support mechanism 3 stable during use. At this time, the workbench is fully extended. Release the brake of the brake wheel in the universal wheel 12, move the workbench to a suitable position, and then step on the brake to fix the position of the workbench. Remove the top plate from the platform 31. Use the power cord to connect the telescopic rod 21 to the original external power supply. Pass the original connecting parts through the hole in the horizontal motor to be tested and then through the suitable first mounting hole 311. Install the horizontal motor to be tested on the platform 31 or the first support plate 34 to perform the corresponding motor test. During the test, the terminal device can be used to control the extension and retraction of the four telescopic rods 21 at the same time to adjust the ground distance of the support mechanism 3 and the motor, which is convenient for the user to operate.

[0037] When the motor to be tested is a vertical motor, unscrew the two fourth nuts 342 at one end of the first support plate 34 in sequence to disconnect the connection between the first support plate 34 and the second connecting shaft 314. Pull out the insertion rod 341 from the second connecting hole 313. After separating the first support plate 34 from the reserved slot 312, place it aside. Insert the insertion rod 341 of the connecting rod at one end of the second support plate 35 into the second connecting hole 313 and screw the nut on the outside of the insertion rod 341. Connect the second support plate 35 to the two second connecting shafts 314. The second support plate 35 is now installed. After passing the output shaft of the vertical motor to be tested through the reserved hole 351, pass the original connecting parts through the appropriate second mounting hole 352 and connect them to the connecting hole built into the vertical motor. Install the vertical motor on the second support plate 35, and the corresponding motor test can be performed.

[0038] The protective plate 4, bearing plate 11, caster wheel 12, telescopic rod 21, first mounting base 211, first connecting base 212, second mounting base 22, limiting plate 221, first connecting shaft 23, first nut 231, first bolt 24, second nut 241, platform 31, second connecting base 32, second bolt 33, third nut 331 and fourth nut 342 in the motor testing lifting workbench disclosed in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.
