Description

Technical Field

[0001] This utility model relates to the field of door and window installation technology, specifically to a hoisting mechanism for door and window installation. Background Technology

[0002] With the development of building industrialization and prefabricated technology, the traditional door and window installation mode that relies on manual handling and simple hoisting tools is no longer able to meet the safe and efficient construction needs of large-size, high-performance doors and windows, especially in high-rise buildings and confined work environments. Therefore, when hoisting doors and windows on high floors, people usually use door and window installation hoisting mechanisms to carry out precise hoisting operations, thereby ensuring the safety and efficiency of door and window installation on higher floors.

[0003] In the prior art, patent CN221500423U discloses a hoisting structure for installing building doors and windows, including a base plate, with support wheels installed at the four corners of the bottom end of the base plate, a counterweight placed on one side of the top end of the base plate, an L-shaped guide bracket welded to the middle of the top end of the base plate, and a winding machine installed on the other side of the top end of the base plate. A traction rope is wound inside the winding machine, and two traction branches are installed at one end of the traction rope. Each of the two traction branches is equipped with a limit bracket at one end.

[0004] The hoisting structure for installing doors and windows in this type of building has the following disadvantages: when fixing the doors and windows, it is necessary to place them between two limiting brackets, and then set three sets of pull ropes between the limiting brackets to fix the doors and windows. At the same time, after the doors and windows are hoisted to a high place, the three pull ropes need to be removed before the doors and windows can be taken out. The operation process is cumbersome and affects the hoisting efficiency of doors and windows. To this end, we propose a hoisting mechanism for installing doors and windows. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a hoisting mechanism for installing doors and windows. By hoisting the components, the doors and windows are pushed to the middle of the mounting seats on the left and right sides. Then, the electric push rod is activated to drive the locking block to move, thereby squeezing the sliding rod to move so that the pressure block synchronously squeezes and fixes the upper and lower surfaces of the doors and windows. At the same time, with the rollers inside the mounting seats, it is easy to push the doors and windows in and pull them out. The fixing process is simple and fast, which improves the hoisting efficiency of doors and windows and can effectively solve the problems in the background art.

At the same time, with the rollers inside the mounting base, it is easy to push the door or window in and pull it out. The fixing process is simple and fast, improving the hoisting efficiency of the door or window.

[0008] Furthermore, a control switch assembly is provided on the outside of the base, and the input end of the control switch assembly is electrically connected to an external power source to control the operation of electrical appliances.

[0009] Furthermore, the hoisting assembly also includes an electric push rod, a locking block, a sliding rod, and a spring. The electric push rods are all fixedly connected to the inside of the mounting frame. The locking blocks are slidably connected inside the mounting base. The telescopic end of the electric push rod is fixedly connected to the adjacent locking block on the same side near the middle of the connecting frame. Sliding rods are slidably connected to the upper and lower sides inside the mounting base. The sliding rods are all installed in conjunction with the locking blocks located in the same mounting base.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3This embodiment provides a technical solution: a hoisting mechanism for installing doors and windows, including a base 1, a support frame 2 fixedly connected to the upper surface of the base 1, a fixed arm 3 rotatably connected to the upper end of the support frame 2, a movable arm 4 slidably connected inside the fixed arm 3, an adjustable connecting frame 10 provided on the lower side of the movable arm 4, a winding roller 5 rotatably connected to the left surface of the support frame 2, a steel wire rope 6 wound around the outer surface of the winding roller 5, and the right end of the steel wire rope 6 fixedly connected to the lower surface of the movable arm 4 (the steel wire rope 6 passes through the fixed arm). The upper surface of the support frame 3 has a limiting hole, and the upper side of the rotating shaft at the right end of the movable arm 4 is finally fixedly connected to the lower surface of the movable arm 4. The right side of the wire rope 6 is slidably connected to the movable pulley 7, and the lower side of the movable pulley 7 is fixedly connected to the hook 8. The connecting frame 10 is fixedly connected to the lower side of the hook 8. The base 1 is equipped with a control switch group 14 on its outside. The input end of the control switch group 14 is electrically connected to an external power source. The rear surface of the support frame 2 is fixedly connected to the motor 12, and the front side of the output shaft of the motor 12 is fixedly connected to the rear surface of the take-up roller 5. The input end of motor 12 is electrically connected to the output end of control switch group 14. By operating control switch group 14, motor 12 is started. The output shaft of motor 12 rotates, driving take-up roller 5 to rotate, causing pulley 7 to move downward, driving hook 8 to move downward, and causing connecting frame 10 to move downward to a suitable position. Hydraulic rod 13 is fixedly connected inside fixed arm 3. The right side of the telescopic end of hydraulic rod 13 is fixedly connected to the inner right surface of movable arm 4. Hydraulic rod 11 is rotatably connected between the right surface of support frame 2 and the lower surface of fixed arm 3. When the external hydraulic cylinder is started, hydraulic rod 11 and hydraulic rod 13 are operated respectively. The telescopic end of hydraulic rod 11 extends or shortens, causing fixed arm 3 to rotate around the rotation connection point between fixed arm 3 and support frame 2, thereby adjusting the angle of fixed arm 3. The telescopic end of hydraulic rod 13 extends or shortens, causing movable arm 4 to slide inside fixed arm 3, thereby adjusting the extension length of movable arm 4, so that the right end of movable arm 4 is in a suitable position. It also includes hoisting component 9.

[0022] Lifting assembly 9 includes a mounting frame 91, mounting base 92, fixing block 93, roller 94, and pressure block 95. The mounting frame 91 is fixedly connected to the front and rear sides of the lower surface of the connecting frame 10. Mounting bases 92 are evenly distributed and fixedly connected to the side of the mounting frame 91 closest to the middle of the connecting frame 10. Fixing blocks 93 are fixedly connected to the lower inside of each mounting base 92. Rollers 94 are rotatably connected to the inside of each fixing block 93. Pressure blocks 95 are slidably connected to the upper and lower inside of each mounting base 92. The lifting assembly 9 also includes an electric push rod 96, a locking block 97, a sliding rod 98, and a spring 99. The electric push rod 96 is fixedly connected to the inside of the mounting frame 91. The locking blocks 97 are slidably connected to the inside of each mounting base 92. The telescopic end near the middle of the connecting frame 10 is fixedly connected to the adjacent locking block 97 on the same side. Sliding rods 98 are slidably connected to the upper and lower sides of the mounting base 92. Each sliding rod 98 cooperates with the locking block 97 located within the same mounting base 92. Pressure blocks 95 are fixedly connected to the side of the sliding rod 98 near the middle of the mounting base 92. Springs 99 are fixedly connected between the side of the sliding rod 98 near the middle of the mounting base 92 and the inner wall of the mounting base 92. The input end of the electric push rod 96 is electrically connected to the output end of the control switch group 14. The door and window are placed horizontally and pushed to the middle between the left and right mounting bases 92, so that the lower surface of the door and window contacts the roller 94, facilitating the pushing of the door and window to the middle of the mounting base 92 and the horizontal pushing of the door and window. When the desired position is reached, operate the control switch group 14 to activate the electric push rod 96. The telescopic end of the electric push rod 96 extends, pushing the locking block 97 towards the center of the connecting frame 10. The locking block 97 has inclined grooves on both its upper and lower sides, and the slide rod 98 has inclined surfaces on the side near the mounting frame 91. Adjacent inclined grooves and inclined surfaces on the same side are slidably connected. The locking block 97 moves to the right, causing the inclined grooves to move to the right. The inclined grooves press against the inclined surfaces, causing two vertically adjacent slide rods 98 to move towards each other (the left and right surfaces of the slide rod 98 are limited by the left and right inner walls of the mounting base 92, and by the sliding limit between the mounting base 92 and the pressure block 95, so that the slide rod 98 can only slide vertically). This causes the vertically adjacent pressure blocks 95 to move towards each other, thereby clamping the door and window, and the spring... 99 retracts, then reverses motor 12. The output shaft of motor 12 reverses, driving the take-up roller 5 to reverse, causing the wire rope 6 to wind around the outer surface of the take-up roller 5. This causes the movable pulley 7 to move upward, driving the hook 8 to move upward, causing the connecting frame 10 to move upward, driving the mounting frame 91 to move upward, and causing the mounting base 92 to move upward, thereby hoisting the door and window. When the door and window are moved to the appropriate position, operate the control switch group 14 to retract the telescopic end of the electric push rod 96, causing the locking block to move away from the connecting frame 10. The spring 99 becomes vertical, pushing the slide rod 98 to reset, driving the pressure block 95 to reset. The door and window are placed on the upper side of the pulley 94. Then, the door and window are pulled out from the inside of the mounting bases 92 on the left and right sides to complete the door and window hoisting operation.

[0023] The working principle of the hoisting mechanism for door and window installation provided by this utility model is as follows: When using this hoisting mechanism to hoist doors and windows, the external hydraulic cylinder is activated, causing hydraulic rod 11 and hydraulic rod 23 to operate respectively. The telescopic end of hydraulic rod 11 extends or retracts, causing the fixed arm 3 to rotate around the rotational connection point between the fixed arm 3 and the support frame 2, thereby adjusting the angle of the fixed arm 3. The telescopic end of hydraulic rod 23 extends or retracts, causing the movable arm 4 to slide inside the fixed arm 3, thereby adjusting the extension length of the movable arm 4. With the right end of boom 4 in a suitable position, operate control switch group 14 to start motor 12. The output shaft of motor 12 rotates, driving the take-up roller 5 to rotate, causing the movable pulley 7 to move downwards, driving the hook 8 to move downwards, and causing the connecting frame 10 to move downwards to a suitable position. Place the door / window horizontally and push it to the middle between the mounting seats 92 on both sides, so that the lower surface of the door / window contacts the roller 94, making it easier to push the door / window to the middle of the mounting seat 92. When the door / window is pushed horizontally to a suitable position, operate control switch group 14 to start electric push rod 96. The telescopic end of electric push rod 96 extends... The length of the push block 97 is pushed towards the middle of the connecting frame 10. Sloping grooves are provided on both the upper and lower sides of the push block 97. Sloping surfaces are provided on the side of the slide rod 98 closest to the mounting frame 91. Adjacent sloping grooves and surfaces on the same side are slidably connected. The push block 97 moves to the right, causing the sloping grooves to move to the right. The sloping grooves press against the sloping surfaces, causing two vertically adjacent slide rods 98 to move towards each other, thus causing the vertically adjacent pressure blocks 95 to move towards each other, thereby clamping the door and window. The spring 99 contracts, and then the reverse motor 12 reverses. The output shaft of the motor 12 reverses, causing the winding roller 5 to reverse, so that the wire rope 6 is wound around the outer surface of the winding roller 5. The pulley 7 moves upward, causing the hook 8 to move upward, the connecting frame 10 to move upward, the mounting frame 91 to move upward, and the mounting base 92 to move upward, thus hoisting the door and window. When the door and window are moved to the appropriate position, the control switch group 14 is operated to retract the telescopic end of the electric push rod 96, causing the locking block to move away from the connecting frame 10, the spring 99 becomes vertical, pushes the slide rod 98 to reset, and drives the pressure block 95 to reset. The door and window are placed on the upper side of the pulley 94. Then, the door and window are pulled out from the inside of the mounting bases 92 on the left and right sides to complete the door and window hoisting operation.

[0024] It is worth noting that the electric actuator 96 disclosed in the above embodiments is an LAP series electric actuator, the motor 12 is a YE3-80M2-4, and the control switch group 14 is provided with control buttons that correspond one-to-one with the electric actuator 96 and the motor 12 and are used to control their switches.

[0025] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
