[0035] This utility model proposes a lifting unit testing machine.

[0036] In the embodiments of this utility model, such as Figures 1 to 6 As shown, the lifting unit testing machine includes:

[0037] The machine tray 1 is provided with a first receiving cavity 11 and a guide groove 12. The first receiving cavity 11 extends to one side wall of the machine tray 1 in the width direction to form a first opening 111. The guide groove 12 extends along the length direction of the machine tray 1 and penetrates the machine tray 1. The guide groove 12 is connected to the first receiving cavity 11.

[0038] A mounting base 3 for installing the lifting unit 2 is disposed within the first receiving cavity 11. The mounting base 3 has a mounting hole 31 and a stabilizing structure 32. The mounting hole 31 extends through the mounting base 3 along the width direction of the machine support 1. The stabilizing structure 32 includes a mounting frame 321 and several clamping units 322. The inner frame edge of the mounting frame 321 is located on the outer periphery of the mounting hole 31, and the outer frame edge of the mounting frame 321 protrudes relative to the mounting base 3 and is detachably connected to the outer periphery of the first opening 111. The clamping units 322 are disposed on the mounting frame 321. The ends of the clamping units 322 move closer to and further away from the center of the first opening 111 to clamp and release the lifting unit 2.

[0039] Rack 4 is disposed in guide groove 12 to engage with lifting unit 2.

[0040] In this lifting unit testing machine, the mounting base 3 is provided with mounting holes 31 and a stabilizing structure 32. The stabilizing structure 32 includes a mounting frame 321 and several clamping units 322. The clamping units 322 are set in the mounting frame 321. By combining the mounting frame 321 and the clamping units 322, the lifting unit 2 to be tested can be clamped and released, which can stabilize the lifting unit 2, effectively avoiding vibration or shaking of the lifting unit 2 during the test, improving the overall stability of the lifting unit 2, thereby improving the accuracy of the test results, making the test data more accurate, and truly reflecting the actual performance of the lifting unit 2. This lifting unit testing machine solves the technical problem of poor stabilization effect of existing testing devices on the lifting unit, the lifting unit being prone to vibration or shaking, resulting in low accuracy of test results and difficulty in accurately reflecting the actual performance of the lifting unit.

[0041] To elaborate further, such as Figure 5 As shown, the lifting unit 2 includes at least a support base 21, a gear 22, a rear cover 23, and a drive shaft. The drive shaft is rotatably mounted inside the support base 21, with one end extending out of the support base 21. The outer periphery of the end extending out of the support base 21 is fixedly connected to the gear 22 to drive the gear 22 to rotate. The end extending out of the support base 21 is provided with a rear cover 23. When the lifting unit 2 is installed, the support base 21 is placed in the mounting hole 31 of the mounting base 3, and the gear 22 passes through the mounting hole 31 and meshes with the rack 4. In some optional embodiments, the end of the clamping unit 322 moves toward the center of the first opening 111 and abuts against the support base 21, thereby clamping and fixing the lifting unit 2. When the drive shaft drives the gear 22 to rotate, it can drive the rack 4 to translate.

[0042] In one embodiment of the present invention, the side wall of the machine tray 1 opposite to the first opening 111 is provided with a second opening 112 for the rear cover 23 to pass through.

[0043] like Figure 2 , 6 As shown in Figure 7, in one embodiment of this application, the machine tray 1 is provided with a second receiving cavity 13, which extends to the side wall of the machine tray 1 where the first opening 111 is provided. The second receiving cavity 13 is provided with a motor base 5, which includes a supporting inner cylinder 51 and a housing 52 that matches the second receiving cavity 13. The side wall of the supporting inner cylinder 51 is provided with a plurality of first through holes 511, and the side wall of the supporting inner cylinder 51 is connected and fixed to the housing 52 by a first reinforcing rib 53.

[0044] This lifting unit testing machine, by setting a second receiving cavity 13 and a motor base 5, with the outer shell 52 of the motor base 5 matching the second receiving cavity 13, is suitable for testing lifting units 2 equipped with motors 26. The supporting inner cylinder 51 is used to house the motor 26. The side wall of the supporting inner cylinder 51 has several first through holes 511. This structural design of the motor base 5 provides high structural strength, and the first through holes 511 give the supporting inner cylinder 51 a certain elastic deformation capacity. During testing, when the motor 26 vibrates due to operation, in addition to providing stable support for the motor 26, it can also effectively absorb and reduce the collision force generated between the motor 26 and the supporting inner cylinder 51, avoiding damage caused by direct collision, extending the service life of this lifting unit testing machine, and ensuring that the overall structure of the lifting unit 2 remains intact.

[0045] In one embodiment of this utility model, such as Figure 5 As shown, the lifting unit 2 also includes a connecting plate 24, a housing 25, a motor 26, and a transmission assembly. The motor 26 and the support base 21 are located on the same side of the housing 25, and the motor 26 and the support base 21 are respectively connected to the housing 25. The connecting plate 24 is sleeved on the outside of the support base 21 and is located close to the housing 25. The transmission assembly is located inside the housing 25. The output end of the motor 26 is connected to the transmission assembly to drive the transmission assembly to rotate. The end of the transmission assembly away from the motor 26 is connected to the transmission shaft, and the transmission shaft drives the gear 22 to rotate. When the lifting unit 2 is installed, the side of the connecting plate 24 facing away from the housing 25 abuts against the end face of the mounting base 3 away from the guide groove 12. The transmission assembly can be any one of a belt drive assembly or a gear drive assembly.

[0046] Preferably, the first receiving cavity 11, the second receiving cavity 13, and the outer shell 52 are all square in shape.

[0047] like Figure 7 As shown, in one embodiment of this application, the inner support cylinder 51 includes a first end ring 512, a second end ring 513, and a plurality of connecting strips 514. The plurality of connecting strips 514 are arranged in a ring array at intervals. One end of each connecting strip 514 is connected to the first end ring 512, and the other end is connected to the second end ring 513. A first through hole 511 is formed between adjacent connecting strips 514.

[0048] Through the above-mentioned structural arrangement of the inner support cylinder 51, the motor base 5 can stably support the motor 26. The first through hole 511 is formed between the adjacent connecting strips 514, so that the inner support cylinder 51 has a certain elastic deformation capability. When the motor 26 vibrates or shakes, the inner support cylinder 51 can effectively absorb and weaken the collision force generated between the motor 26 and the motor base 5, avoid damage caused by direct collision, and extend the service life of this lifting unit testing machine.

[0049] In one embodiment of this utility model, the supporting inner cylinder 51 further includes several reinforcing ring segments 515, with each end of a reinforcing ring segment 515 correspondingly connected to two adjacent connecting strips 514. The reinforcing ring segments 515 can further enhance the structural strength of the supporting inner cylinder 51, thereby improving the ability of the motor base 5 to resist external pressure and deformation, ensuring the structural stability of the motor base 5 during testing, and extending its service life.

[0050] Preferably, the inner support cylinder 51 is an integral structure.

[0051] Preferably, a plurality of first through holes 511 are provided, and the plurality of first through holes 511 are symmetrically distributed about the central axis of the supporting inner cylinder 51. This ensures that the motor base 5 is subjected to balanced forces in all directions, more effectively absorbs and disperses vibration energy, and improves the overall balance and stability of the motor base 5.

[0052] like Figure 7 As shown, in one embodiment of this application, the motor base 5 further includes two arc-shaped reinforcing members 54. The two arc-shaped reinforcing members 54 are disposed between the supporting inner cylinder 51 and the outer shell 52. The two arc-shaped reinforcing members 54 are symmetrically arranged. The two ends of each arc-shaped reinforcing member 54 along its own extension direction abut against the two inner walls of the outer shell 52 that are disposed opposite to each other. The side wall of the arc-shaped reinforcing member 54 is provided with a plurality of second through holes 541. The side wall of the arc-shaped reinforcing member 54 is connected and fixed to the supporting inner cylinder 51 by a second reinforcing rib 55.

[0053] Two arc-shaped reinforcing members 54 are located between the inner support cylinder 51 and the outer shell 52, and are connected to both the inner support cylinder 51 and the outer shell 52. Therefore, stress can be transferred from the inner support cylinder 51 to the outer shell 52, thereby distributing stress more evenly in the motor base 5. In addition, by setting two arc-shaped reinforcing members 54 and a second reinforcing rib 55, the structural strength of the inner support cylinder 51 is further improved, so that the motor base 5 provides stable support for the motor 26.

[0054] like Figures 1 to 3 As shown, in one embodiment of this application, a plurality of pressing units 322 are arranged on both sides of the first opening 111 along the length direction of the machine support 1;

[0055] The clamping unit 322 includes a bolt 3221, a pressure block 3222 and a buffer block 3223. One end of the bolt 3221 passes through the mounting frame 321 and is connected to the pressure block 3222. The end of the pressure block 3222 away from the bolt 3221 is connected to the lifting unit 2 through the buffer block 3223.

[0056] The mounting frame 321 has a first threaded hole 3211 that matches the bolt 3221 through the height direction of the support 1.

[0057] The clamping unit 322 includes a bolt 3221, a pressure block 3222, and a buffer block 3223. The mounting frame 321 has a first threaded hole 3211 that matches the bolt 3221 through it along the height direction of the machine support 1. At this time, the mounting frame 321 and the bolt 3221 are threadedly connected and tightly connected. When the tester performs the test operation, the lifting unit 2 is clamped and fixed by the mutual cooperation of the bolt 3221 and the mounting frame 321. Moreover, the bolt 3221 and the mounting frame 321 are not easy to loosen during the test, ensuring that the lifting unit 2 can be subjected to a stable and reliable clamping and fixing effect. When it is necessary to tighten the lifting unit 2, simply rotate the bolt 3221, causing it to move the pressure block 3222 and the buffer block 3223 closer to the center of the first opening 111, i.e., towards the lifting unit 2, thereby tightening the lifting unit 2. When it is necessary to loosen the lifting unit 2, rotate the bolt 3221 in the opposite direction, causing the pressure block 3222 and the buffer block 3223 to retract away from the center of the first opening 111. Furthermore, by setting the buffer block 3223 at the end of the pressure block 3222 away from the bolt 3221, when the tightening unit 322 tightens and fixes the lifting unit 2, it can prevent excessive local pressure on the contact area of ​​the lifting unit 2, thus avoiding deformation or damage to the lifting unit 2 and ensuring the integrity of the overall structure of the lifting unit 2. Through the cooperation between the bolt 3221, the pressure block 3222, the buffer block 3223, and the mounting frame 321, the lifting unit 2 can be quickly fixed, effectively improving testing efficiency.

[0058] In one embodiment of this utility model, the buffer block 3223 of each pressing unit 322 is connected to the connecting plate 24 of the lifting unit 2.

[0059] Preferably, the buffer block 3223 is made of existing rubber material.

[0060] like Figure 1 , 2 As shown in Figure 4, in one embodiment of this application, a plurality of pressing units 322 are symmetrically arranged on both sides of the first opening 111 along the length direction of the machine tray 1, and the plurality of pressing units 322 located on the same side of the first opening 111 are arranged at intervals.

[0061] Several clamping units 322 are symmetrically arranged on both sides of the first opening 111 along the length of the machine support 1, and the clamping units 322 located on the same side of the first opening 111 are arranged at intervals. After the lifting unit 2 is installed, the clamping units 322 can not only enhance the stability of the lifting unit 2, but also ensure that the lifting unit 2 is subjected to pressure evenly, reducing the risk of deformation or damage to the lifting unit 2 due to uneven force.

[0062] Preferably, the number of clamping units 322 is four.

[0063] like Figures 1 to 4 As shown in Figure 6, in one embodiment of this application, the stabilizing structure 32 further includes a plurality of positioning blocks 323, each positioning block 323 being fixedly connected to the machine support 1, and positioning blocks 323 being provided on both sides of each corner of the mounting frame 321.

[0064] By setting positioning blocks 323 on both sides of each corner of the mounting frame 321, the mounting frame 321 is effectively limited and fixed, which enhances the structural stability of the mounting frame 321 during the test process, and enables the connecting plate 24 of the lifting unit 2 to be reliably pressed and fixed. In addition, it can also improve the ease of installation of the mounting frame 321.

[0065] Preferably, the positioning block 323 is fixedly connected to the machine support 1 by welding.

[0066] like Figure 6 and 8 As shown, in one embodiment of this application, the end face of the mounting base 3 away from the guide groove 12 is provided with a second threaded hole 33; the mounting frame 321 is provided with a first fixing hole 3212 through it along its own thickness direction, and the side wall of the machine support 1 near the first opening 111 is provided with a third threaded hole 14 corresponding to the first fixing hole 3212.

[0067] By setting the second threaded hole 33 and the third threaded hole 14, the lifting unit 2 and the mounting base 3, and the mounting frame 321 and the machine support 1 can be tightly connected together by bolts. In this way, under the tightening action of the bolts and the pressing action of several pressing units 322, it can be further ensured that the lifting unit 2 is firmly and stably pressed and fixed, and the stability of the entire structure of this lifting unit testing machine can be improved, further ensuring the accuracy of the test results.

[0068] In one embodiment of this utility model, a second fixing hole 241 is provided through the connecting plate 24 along its thickness direction. A bolt passes through the second fixing hole 241 of the connecting plate 24 and is threadedly connected to the second threaded hole 33 of the mounting base 3, thereby achieving a stable connection between the connecting plate 24 and the mounting base 3. Another bolt passes through the first fixing hole 3212 and is threadedly connected to the third threaded hole 14, thereby achieving a stable connection between the mounting frame 321 and the machine support 1.

[0069] like Figure 6 As shown, in one embodiment of this application, the number of first receiving cavities 11 and the number of second receiving cavities 13 are both two, and the two first receiving cavities 11 and the two second receiving cavities 13 are symmetrically distributed along the height direction of the machine support 1.

[0070] The first receiving cavity 11 and the second receiving cavity 13 are both provided in pairs. This allows two lifting units 2 to be installed on the machine support 1 simultaneously, enabling testing with two lifting units 2 and improving testing efficiency. Furthermore, both the lifting unit 2 and the stabilizing structure 32 are provided in pairs, with the two lifting units 2 spaced apart.

[0071] like Figure 1 , 2 As shown in Figures 6 and 7, in one embodiment of this application, the lifting unit testing machine further includes a hydraulic cylinder 6, the output end of which is connected to one end of the rack 4 for transmission, and the hydraulic cylinder 6 is connected to a hydraulic station to input hydraulic oil.

[0072] During testing, the load operation quality of the two lifting units 2 can be tested and judged one by one. The hydraulic station inputs hydraulic oil into the cylinder 6, and then outputs the rated load to one of the lifting units 2 through the rack 4. The other lifting unit 2 is in an unloaded state, so the rated load operation quality of the first lifting unit 2 can be tested and judged. The testing process of the other lifting unit 2 is the same.

[0073] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
