Description

Technical Field

[0001] This utility model relates to the field of glass hoisting technology, specifically to a glass hoisting frame. Background Technology

[0002] Curtain wall glass is a special type of glass used in the exterior envelope or decorative structure of buildings. Due to its large size, curtain wall glass usually needs to be hoisted and moved using suction cup lifting frames. Suction cup lifting frames can easily and quickly move curtain wall glass to a designated location, thereby improving the efficiency of glass installation.

[0003] Existing patent application number: 202022187227.5 A lifting device for handling tempered glass includes a housing, the housing being vertical, and a circular groove being formed along its axial direction inside the housing. A piston and a spring are fitted into the circular groove, and the piston is horizontal, located at the top of the spring. A threaded hole is formed at the top of the housing, the threaded hole extending vertically through the top of the housing and communicating with the circular groove. A lead screw is threaded into the threaded hole, the lead screw passing through the threaded hole. A connecting rod is fixedly connected radially to the circumferential outer wall at the bottom of the housing, and the connecting rods are arranged in a ring array about the housing.

[0004] The aforementioned patent describes a functional structure for a suction cup lifting frame. In the prior art, the frame of a suction cup lifting frame is usually a one-piece structure. The suction cups on the one-piece lifting frame are spaced at a fixed distance, which makes it difficult to adjust according to the glass size in actual use. There are also lifting frames on the market that use adjustable structures to fix the movable frame with bolts. The bolts need to be disassembled and reassembled before and after adjustment, which is a cumbersome process. Moreover, the adjustable accuracy of the suction cups is relatively low due to the influence of the bolt hole spacing, which is difficult to meet the user's needs. Therefore, we propose a glass lifting frame to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a glass lifting frame to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a glass lifting frame, comprising a fixed frame, a vacuum pump, a fixed suction cup, and a stepless adjustment mechanism. The fixed frame has vacuum pumps symmetrically installed on both sides of its center. Fixed suction cups are installed at the four corners of the front and rear sides of the fixed frame. A stepless adjustment mechanism is provided at the four corners of the left and right sides of the fixed frame. The stepless adjustment mechanism includes a motor housing, a dual-axis motor, a connecting beam, a through groove, a screw, a movable frame, a threaded sleeve, a movable suction cup, and a reinforcing support mechanism. The motor housing is embedded in the middle of the front and rear sides of the fixed frame, and a dual-axis motor is installed inside the motor housing. A connecting beam is integrally provided at the four corners of the left and right sides of the fixed frame. The connecting beam has a through groove at its end, which passes through the fixed frame and connects to the inside of the motor housing. The through groove is rotatably mounted with a bearing seat and a screw. The first end of the screw is connected to the output shaft of the dual-axis motor. The fixed frame has symmetrically arranged movable frames on its left and right sides. The movable frames are slidably sleeved on the surface of the connecting beam. A threaded sleeve is slidably arranged inside the through groove. The threaded sleeve is threadedly screwed to the outside of the end of the screw. The end of the threaded sleeve extends out of the through groove and is bolted to the inner side wall of the movable frame. Movable suction cups are installed at the front and rear ends of the movable frame. Both the movable suction cups and the fixed suction cups are connected to the vacuum pump negative pressure interface through air pipes. A reinforcing support mechanism is provided in the middle of the left and right sides of the fixed frame.

[0007] Preferably, the cross-sectional shape of the threaded sleeve and the through groove is rectangular.

[0008] Preferably, the movable frame is a hollow structure.

[0009] Preferably, the movable suction cup and the vacuum pump are connected by a spiral flexible hose.

[0010] Preferably, the screws on the left and right sides of the dual-axis motor have opposite helical directions.

[0011] Preferably, the reinforcing support mechanism includes a telescopic sleeve, a telescopic bar, and a bracket. The middle of the left and right sides of the fixed frame is bolted to the telescopic sleeve. The telescopic sleeve is horizontally set. The telescopic bar is slidably installed inside the telescopic sleeve. The end of the telescopic bar extends out of the inside of the telescopic sleeve and is welded and fixed to the bracket. The bracket is fastened to the middle of the movable frame from bottom to top and bolted to it.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention features stepless adjustment mechanisms at the four corners of the left and right sides of the fixed frame. By activating a dual-axis motor to drive the screw forward, the screw drives the threaded sleeve outward along the through groove, thereby controlling the movable frame to slide away from the fixed frame along the connecting beam. This increases the distance between the movable and fixed suction cups, better accommodating the hoisting of large-sized curtain wall glass. When the dual-axis motor is activated to drive the screw in reverse, the screw drives the threaded sleeve inward along the through groove, controlling the movable frame to slide closer to the fixed frame along the connecting beam. This decreases the distance between the movable and fixed suction cups, better accommodating the hoisting of small-sized curtain wall glass. The distance between the movable and fixed suction cups can be adjusted on-site according to the size of the curtain wall glass, offering strong size adaptability and making hoisting work more efficient and convenient.

[0014] This utility model features a reinforcing support mechanism at the center of the left and right sides of the fixed frame. This reinforces the connection between the movable frame and the fixed frame, ensuring the movable frame is securely installed. Furthermore, the telescopic bar can extend and retract synchronously within the telescopic sleeve as the movable frame is adjusted, without obstructing the normal adjustment of the movable frame.

Detailed Implementation

[0021] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0022] Please see Figure 1This utility model provides a glass lifting frame, including a fixed frame 1, a vacuum pump 2, a fixed suction cup 3 and a stepless adjustment mechanism 4. The vacuum pump 2 is symmetrically installed on the left and right sides of the center of the fixed frame 1, the fixed suction cup 3 is installed at the four corners of the front and rear sides of the fixed frame 1, and the stepless adjustment mechanism 4 is provided at the four corners of the left and right sides of the fixed frame 1.

[0023] Please see Figure 2-4 This utility model provides a glass lifting frame. The stepless adjustment mechanism 4 includes a motor housing 41, a dual-axis motor 42, a connecting beam 43, a through groove 44, a screw 45, a movable frame 46, a threaded sleeve 47, a movable suction cup 48, and a reinforcing support mechanism 49. The motor housing 41 is embedded in the middle of the front and rear sides of the fixed frame 1. The dual-axis motor 42 is installed inside the motor housing 41. The connecting beam 43 is integrally provided at the four corners of the left and right sides of the fixed frame 1. The end of the connecting beam 43 has a through groove 44. The through groove 44 passes through the fixed frame 1 and connects to the inside of the motor housing 41. The screw 45 is rotatably installed inside the through groove 44 using a bearing seat. The head end of the screw 45 is connected to the dual-axis motor 46. 2. The output shaft is connected. The fixed frame 1 is symmetrically provided with movable frames 46 on the left and right sides. The movable frames 46 are slidably sleeved on the surface of the connecting beam 43. The threaded sleeve 47 is slidably provided in the through groove 44. The threaded sleeve 47 is threadedly connected to the outside of the end of the screw 45. The end of the threaded sleeve 47 extends out of the through groove 44 and is bolted to the inner side wall of the movable frame 46. The movable suction cups 48 are installed at the front and rear ends of the movable frame 46. The movable suction cups 48 and the fixed suction cups 3 are both connected to the negative pressure interface of the vacuum pump 2 through air pipes. The vacuum pump 2 generates negative pressure to realize the adsorption function of the movable suction cups 48 and the fixed suction cups 3. The middle of the left and right sides of the fixed frame 1 is provided with a reinforcing support mechanism 49.

[0024] During use, when it is necessary to adjust the distance between the movable suction cup 48 and the fixed suction cup 3, the dual-axis motor 42 is started to drive the screw 45 to rotate forward. During this process, the screw 45 drives the threaded sleeve 47 to move outward along the through groove 44, thereby controlling the movable frame 46 to slide away from the fixed frame 1 along the connecting beam 43, thus widening the distance between the movable suction cup 48 and the fixed suction cup 3 to better adapt to the hoisting operation of large-size curtain wall glass. When the dual-axis motor 42 is started to drive the screw 45 to rotate in reverse, the screw 45 drives the threaded sleeve 47 to move inward along the through groove 44, controlling the movable frame 46 to slide closer to the fixed frame 1 along the connecting beam 43, thus narrowing the distance between the movable suction cup 48 and the fixed suction cup 3 to better adapt to the hoisting operation of small-size curtain wall glass. The distance between the movable suction cup 48 and the fixed suction cup 3 can be adjusted on-site according to the size specifications of the curtain wall glass, with strong size adaptability, making the hoisting work more efficient and convenient.

[0025] To further explain, the cross-sectional shape of the threaded sleeve 47 and the through groove 44 is rectangular, which restricts the rotation of the threaded sleeve 47 and ensures that the threaded sleeve 47 can be normally bolted to the movable frame 46.

[0026] To further explain, the movable frame 46 is a hollow structure, which ensures the lightweight of the movable frame 46 and reduces the weight load of the connecting beam 43.

[0027] To further explain, the movable suction cup 48 and the vacuum pump 2 are connected by a spiral flexible hose. The spiral flexible hose is spring-shaped and has good elasticity to better adapt to changes in the distance between the movable suction cup 48 and the vacuum pump 2.

[0028] To further explain, the screws 45 on the left and right sides of the dual-axis motor 42 have opposite spiral directions, which can control the moving frames 46 on the left and right sides to move closer to or away from the fixed frame 1 synchronously, so that all the moving suction cups 48 and the fixed suction cups 3 can adjust their spacing synchronously.

[0029] Please see Figure 5 This utility model provides a glass hoisting frame. The reinforcing support mechanism 49 includes a telescopic sleeve 491, a telescopic bar 492, and a bracket 493. The middle of the left and right sides of the fixed frame 1 is bolted to the telescopic sleeve 491. The telescopic sleeve 491 is horizontally set. The telescopic bar 492 is slidably installed inside the telescopic sleeve 491. The end of the telescopic bar 492 extends out of the inside of the telescopic sleeve 491 and is welded and fixed to the bracket 493. The bracket 493 is fastened to the middle of the movable frame 46 from bottom to top and bolted to it.

[0030] During installation, first, the movable frame 46 is inserted into the inner side of the bracket 493 and bolted in place to complete the initial connection. The connection strength between the movable frame 46 and the fixed frame 1 is enhanced by the reinforcing support mechanism 49, ensuring that the movable frame 46 is installed firmly. The telescopic bar 492 can extend and retract synchronously inside the telescopic sleeve 491 as the movable frame 46 is adjusted and moved, without hindering the normal adjustment of the movable frame 46. Then, the movable frame 46 is pushed to fit onto the outside of the connecting beam 43 until the threaded sleeve 47 abuts against the inner wall of the movable frame 46. Bolts can then be used to install and lock the threaded sleeve 47 to the movable frame 46, thus completing the assembly of the movable frame 46 and the fixed frame 1. The connection operation is simple and convenient for subsequent disassembly and maintenance.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
