The objects, technical solutions and advantages of the present utility model will become more apparent by the following detailed description of the present utility model with reference to the accompanying drawings. It should be understood that the description is only illustrative and is not intended to limit the scope of the utility model. In addition, in the following description, descriptions of well-known structures and techniques are omitted so as not to unnecessarily obscure the present utility model.
The specific embodiment is as follows: referring to fig. 1-3, a lifting device for maintaining a numerically-controlled machine tool comprises a bracket 1, a winch motor 4 is arranged at the top of the bracket 1, a rotating shaft 41 is arranged on an output shaft of the winch motor 4, two first fixed pulleys 5 are arranged on two sides of the top of the bracket 1, two first steel wire ropes 3 are wound on the rotating shaft 41, a lifting frame 2 in a square frame shape is arranged inside the bracket 1, the lifting frame 2 is in a horizontal state, guide cylinders 21 are arranged on two sides of the lifting frame 2, lifting forks 22 are slidably connected with the guide cylinders 21, the lifting forks 22 are four and are slidably connected with two ends of the two guide cylinders 21 respectively, and the two first steel wire ropes 3 are wound on two sides of the top of the lifting frame 2 respectively after bypassing the two first fixed pulleys 5, and further comprise a tension stabilizing system capable of restraining the lifting frame 2 from tilting and shaking.
Specifically, in combination with fig. 3, the tension stabilizing system is composed of four constant-length tension devices, the constant-length tension devices include a second steel wire rope 6, two second fixed pulleys 7 and a third fixed pulley 8, the two second fixed pulleys 7 are respectively located at two sides of the first steel wire rope 3 and fixed on the lower surface of the top of the support 1, one end of the second steel wire rope 6 is connected with the upper surface of one corner of the lifting frame 2, the other end sequentially passes through the second fixed pulleys 7 at the same side (the same side as the first steel wire rope 3) and the different side (the same side as the second fixed pulleys located at the other side of the first steel wire rope 3) and then downwards passes through the third fixed pulleys 8 fixed on the support 1 and located below the lifting frame 2, and then upwards connected to the lower surface of the other corner of the lifting frame 2, the two corners are respectively located at two sides of the first steel wire rope 3, the extending direction of the second steel wire rope 6 is parallel or perpendicular to the horizontal plane except for the part contacted with the second fixed pulleys 7 and the third fixed pulleys 8, the second fixed pulleys 7 on the right side in fig. 3 can be in a synchronous state with the lifting frame 2 or in a state of being located between the second fixed pulleys 7 and the second fixed pulleys 8, and the second fixed pulleys 2 are in a different vertical state or in the same state, and the lifting frame 2 is in a synchronous state. Because the two ends of the second wire rope 6 are respectively located at the two sides of the first wire rope 3 and are respectively located at the upper surface and the lower surface of the lifting frame 2, when only the marked set of constant-length tension devices is present, as shown in fig. 3, the left and right corners of the lifting frame 2 where the end of the second wire rope 6 is located can only rise synchronously (the end of the lifting frame 2 is kept horizontal) or the left corner of the lifting frame 2 is lowered and the left corner of the lifting frame is not raised, the situation that the left corner of the lifting frame is raised and the right corner of the lifting frame is lowered (because the length of the second wire rope 6 is unchanged) does not occur, a set of constant-length tension device is added, one end of the second wire rope 6 in the two sets of constant-length tension devices is respectively located at the two sides of the first wire rope 3, one end of the second wire rope 6 in the second set of constant-length tension devices is fixed at one end of the lower surface of the lifting frame 2, the other end of the second wire rope 6 in the second set of constant-length tension devices is located near the upper surface of the lifting frame 2, the other ends of the second wire rope 6 in the second set are also located near the left end of the upper surface of the lifting frame 2, and the left corner of the two ends of the lifting frame 2 are located near the same, and the two ends of the lifting frame can only be kept at the same horizontal angle (the two ends of the lifting frame and can only are kept at the same horizontal angle). When there are four constant-length tension devices and two ends of the second steel wire rope 6 are respectively connected with the upper and lower surfaces of the four corners of the lifting frame 2, the front and rear ends of the lifting frame 2 can only be kept horizontal in the left-right direction and cannot incline, and the front and rear ends are respectively connected with the two first steel wire ropes 3, so that the lifting frame 2 is basically at the same height in the front-rear direction. Due to the presence of the tension of the four second wire ropes 6, the shaking of the lifting frame 2 in the horizontal direction is also made small. The tension stabilizing system mainly comprises a fixed pulley and a steel wire rope, the weight is lighter, and the fixed pulley and the steel wire rope are common and cheap products in the market, and the cost is lower.
Specifically, a guide post for sliding connection with the guide cylinder 21 is arranged at the top of the lifting fork 22, and a fork body for supporting the bottom of the numerical control machine is arranged at the bottom of the lifting fork 22.
Further, two limiting holes 11 are formed in the top of the support 1, the two first steel wire ropes 3 penetrate through the two limiting holes 11 respectively, the diameter of each limiting hole 11 is slightly larger than that of each first steel wire rope 3, and therefore the first steel wire ropes 3 cannot deviate and fall off from the first fixed pulleys 5.
When the device is used, the lifting frame 2 is moved to the upper part of the numerical control machine tool, then the lifting fork 22 is pushed inwards to enable the fork body to be inserted into the bottom of the numerical control machine tool, and then the hoisting motor 4 is started to enable the lifting frame 2 to lift, so that the lifting frame 2 and the numerical control machine tool shake less due to the existence of the tension stabilizing system, and even if the gravity center of the numerical control machine tool deviates from the center of the lifting frame 2 more (within the range formed by the end parts of all steel wires), the lifting frame is hardly inclined.
The foregoing embodiments are not intended to limit the present utility model, but while the present utility model has been described in detail with reference to the foregoing examples, it will be apparent to those skilled in the art that modifications may be made to the technical solutions described in the foregoing embodiments, or equivalents may be substituted for some of the technical features thereof, and any modifications, equivalents, improvements or changes that fall within the spirit and principle of the present utility model should be included in the scope of protection of the present utility model.
