[0029] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.
[0030] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.
[0031] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.
[0032] In one embodiment, Figure 1 and Figure 1a As shown, the functional testing system 100 of the portable lift includes components such as a support platform 102 and a functional area device 101; the support platform 102 can be fixed on flat ground, and the functional area device 101 includes a motor function testing device 200, a rope grab 105, a rope 103, a portal frame 104, a travel length measuring device 300, a first fixed structure 700, a second fixed structure 800, a tension testing device (structure) 600 and a tensioning structure 400 and other equipment.
[0033] The functional test system 100 can also be called a functional test platform. The test object is a portable lift 500. The rope 103 passes through the rope grab 105, then contacts the travel length measuring device 300, and then passes through the first fixed structure 700 to enter the interior of the portable lift 500. Figure 1aThe lower part of the portable lift 500 is connected to the tension test device 600 through a rope, and the anchor point located at the upper right part of the portable lift 500 is connected to the second fixed structure 800 on the right side of the portal frame 104 .
[0034] In some embodiments, Figure 2b As shown, the motor function test device 200 includes: a motor 204, a reducer 205, a sensor 206, a bearing seat 207 and other components. The sensor includes a torque sensor and a speed sensor, which are connected to the controller through cables. After the motor 204 starts working, the torque and speed data can be tested by the torque sensor and the speed sensor to display on the display screen of the controller.
[0035] like Figure 2a As shown, the rope grab 105 can be connected to the transmission shaft of the motor device 200, and the dotted line in the figure shows the position of the rope 103. When the motor 204 rotates clockwise, the rope grab 105 can also rotate clockwise, and at the same time drive the rope 103 to move along the direction from B to A in the figure. At the same time, the motor function test device 200 can provide a constant clockwise torque. When the motor 204 rotates counterclockwise, it is opposite to the above form; in addition, when the motor 204 starts working, the rotation speed is set to 0 from the controller at the same time. At this time, the entire motor function test device 200 only provides torque, and both clockwise and counterclockwise torques can be provided, and loads in two directions can be provided.
[0036] In some embodiments, Figure 2a As shown, the structure composed of the guide tube 201, the fixing plate 202 and the fixing plate 203 has a function; the fixing plate 202 and the fixing plate 203 clamp the guide tube 201, and after the guide tube 201 is moved to a suitable position, the guide tube 201 can be locked with a screw nut. The function of the guide tube 201 is to guide the rope 103 along the specified path, so that the rope 103 can be prevented from being in a chaotic state here.
[0037] In some embodiments, Figure 3 As shown in FIG. 1 , the dotted line indicates the traveling state of the rope. The rope can travel along the C direction or the D direction. The rope travel length device 300 includes a pulley 301 and an encoder. The pulley 301 is connected to the encoder. Figure 3 The position shown will press the rope 103. When the rope 103 moves along the C direction or the D direction, it will drive the pulley 301 to rotate. At this time, the encoder collects the rotation signal of the pulley 301 and displays the travel length data on the corresponding display. Finally, the travel length data of the rope 103 can be tested.
[0038] In some embodiments, Figure 4a As shown, the tensioning structure 400 includes a fixing seat 401, a fixing plate 402, a lifting ring 403, and a connecting rope (not shown). The tensioning structure 400 can move along the length direction of the through slot of feature F01 on the supporting platform 102 to match the position change of the portable lift 500. Figure 4b As shown, two lifting rings 403 of the tensioning structure 400 are connected to the anchor points of the anchor plate 501 and the anchor plate 502 of the portable lift 500 through connecting ropes.
[0039] In some embodiments, Figure 5a As shown, the tensioning structure 400 is used to make the rope 103 contact the cover plate 503, and then a certain contact angle is formed by adjusting the length of the connecting rope. When measuring the wear of the cover plate 503, different wear amounts can be measured to achieve the purpose of functional testing.
[0040] like Figure 5b As shown, in the entire test state, the dotted line and the solid line are two states of the rope 103, respectively. The normal use state of the portable lift 500 is the solid line state, in which there is contact with Figure 5a in actual use, the rope 103 may not be in vertical contact with the surface of the pulley 504, forming a certain angle, so in order to achieve these special cases in this functional test system, a first fixed structure 700 is added.
[0041] When the rope 103 passes through the first fixing structure 700, it enters the pulley 504 and contacts the pulley 504, and can achieve a state of entering at a certain angle, which is more in line with actual use conditions, and the test results will be more accurate and convincing. Figure 5b As shown, the lower part of the portable lift 500 is connected to the tension testing device 600 via a sling (dashed line), and the right anchor plate 501 is connected to the second fixed structure 800 via a connecting rope.
[0042] When the portable lift 500 starts working, the rope 103 will move along the Figure 5a In order to simulate the actual functional test and test the wear of the pulley 504, it is necessary to provide a load in the opposite direction of D2. At this time, the motor function test device 200 can act as a load. Figure 2a In the state shown, a constant torque in the counterclockwise direction is sufficient. After the load is provided, the portable lift 500 will be lifted up in the opposite direction of D1 under the action of the rope 103. At this time, the portable lift 500 will tighten the tension test device 600 at the bottom, and the tension test device 600 can display the tension value at this time.
[0043] In some embodiments, Figure 6a As shown in FIG. 1 , the tension test device 600 is composed of a tension meter 602, a hanging ring 601, and a display (not shown). The tension meter 602 is fixed on the support platform 102. Figure 6b It can be seen that the tension testing device 600 can be moved along the length direction of the feature F02 through slot to meet the tension testing requirements at different positions.
[0044] In some embodiments, Figure 7 As shown, the first fixed structure 700 is made of a pulley, a sleeve and a locking screw. After the rope 103 passes through the first fixed structure 700, it will enter the interior of the portable lift 500 and form a certain angle α with the pulley 504. In order to achieve different α in actual use, the first fixed structure 700 on the left can rise or fall along the shelf 104 and along the D3 or D4 direction. When adjusted to a suitable position, the locking screw is tightened from the D5 direction, and the locking screw will lock the sleeve on the shelf 104; at the same time, when the rope 103 passes through the first fixed structure 700 and then enters the portable lift 500, the angle α will change, and the adjustment range of the rise or fall of the first fixed structure 700 also determines the change range of the angle α. Similarly, the angle change of the second fixed structure 800 is also consistent with that of the first fixed structure 700. The second fixed structure 800 includes: a sleeve and a locking screw; the sleeve is sleeved on the column located on the other side of the portal frame 104, and the locking screw is used to fix the sleeve.
[0045] The portable lift function test system 100 in the above embodiment can realize the wear test of the pulley 504 and the cover plate 503 of the portable lift and fatigue tests such as heating test, and can also test the wear test and fatigue tests such as heating test of the rope grab (not shown) of the portable lift; the portable lift function test system in the above embodiment is easy to operate, the test process is simple, the test difficulty is low, the test accuracy is high, and the safety of using the portable lift can be improved. The test target of the function test system 100 is not limited to the portable lift 500, and other lifts of the same type can also be measured.
[0046] Each embodiment in this specification is described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referred to each other. For the system embodiment, since it basically corresponds to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.
