Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a hoisting device for building construction. Background Technology

[0002] Construction is a production activity carried out by people using various building materials and machinery according to specific design blueprints within a certain space and time to build various types of building products. It includes the entire production process from construction preparation and groundbreaking to project completion and acceptance. During the construction process, in order to reduce the labor intensity of workers, hoisting equipment can be used to lift and transport building materials. In the prior art, patent CN 220684465 U discloses a safe hoisting device for construction, including a frame, a main motor on one side of the frame, a turntable on the side of the frame near the motor, the output end of the main motor being connected to the turntable, a wire rope on one side of the frame, the wire rope being wound on the turntable, and a lifting device on one end of the wire rope. This utility model, by setting a limiting device, allows personnel to insert the wire rope into a first circular hole, so that the screw rod through the first circular hole assists in limiting the wire rope near the lifting device, while the drive motor drives the screw to rotate, so that the screw... The rod drives the screw hole rod to move up and down, following the movement of the lifting device. This reduces the impact of large swaying of the object due to the swaying of the wire rope when the object moves close to the frame or where personnel are standing, thus improving the stability and convenience of unloading objects. The device limits the swaying of the wire rope through the screw hole rod, thereby improving the stability of lifting construction items. However, the screw hole rod inside the device is adjusted vertically by the screw rod. The length of the screw rod inside the device is limited, which limits the stable range of use of the device for lifting construction items. Therefore, we propose a lifting device for construction.

[0018] 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.

[0019] Please see Figure 1-3This embodiment provides a technical solution: a hoisting device for building construction, including a base 1, a hoisting frame 2 on the upper side of the base 1, an electric hoist 5 on the upper left side of the hoisting frame 2, a load frame 6 at the end of the hoisting rope inside the electric hoist 5, and a single-chip microcomputer 3, which is located on the front side of the hoisting frame 2. The input end of the single-chip microcomputer 3 is electrically connected to an external power source, and the output end of the single-chip microcomputer 3 is electrically connected to the input end of the electric hoist 5. An extension slide rod 4 is slidably connected in a groove on the upper right side of the hoisting frame 2. The right end of the extension slide rod 4 is rotatably connected to a movable pulley 8 through a bearing 2. A movable pulley 9 is rotatably connected to a bearing 3. The concave surfaces of both movable pulleys 8 and 9 slide in contact with the lifting rope inside the electric hoist 5. An electro-hydraulic actuator 10 is provided between the hoisting frame 2 and the extension slide rod 4. The input end of the electro-hydraulic actuator 10 is electrically connected to the output end of the microcontroller 3. Universal wheels 11 are provided at the four lower corners of the base 1, and connecting brackets 12 are provided at the four upper corners of the base 1. An electro-hydraulic actuator 13 is provided at the end of the connecting bracket 12 away from the center of the base 1. The input end of the electro-hydraulic actuator 13 is electrically connected to the output end of the microcontroller 3. A support base 14 is provided at the telescopic end of the electro-hydraulic actuator 13. When using hoisting equipment to operate on items during construction, the casters 11 first facilitate the movement of the equipment to the designated construction point. Then, the operator activates four electro-hydraulic actuators 13 via microcontroller 3, causing their extension ends to lower the corresponding support seats 14 and bring them into contact with the ground. The support seats 14 increase the overall stability of the base 1 during the hoisting equipment's operation. Subsequently, the operator can activate electro-hydraulic actuators 10 via microcontroller 3 according to construction needs, causing their extension ends to drive the extension slide rod 4 to slide horizontally along the groove of the base 1. The horizontal position of the hoisting point of the device is adjusted. When the device hoists building materials, the electric hoist 5 is started by the microcontroller 3. The electric hoist 5 is composed of a motor, transmission mechanism, drum and hoisting rope. The electric hoist 5 uses the operation of raising and lowering its own hoisting rope to realize the raising and lowering operation of the loading frame 6 (the hoisting rope passing through the hoisting frame 2 and the extension slide bar 4 is suspended through the movable pulley 8 and the movable pulley 9 to avoid friction contact between the hoisting rope in the electric hoist 5 and the hoisting frame 2 or the extension slide bar 4 during use). The building materials are loaded through the loading frame 6. The device also includes a balancing mechanism 7.

[0020] Balancing mechanism 7 includes a balancing shell 71, a partition 72, a longitudinal counterweight 73, an electronic level 1 74, a transverse counterweight 75, and an electronic level 2 76. The balancing shell 71 is located in the lower center of the loading frame 6. The partition 72 is located inside the balancing shell 71. The longitudinal counterweight 73 is slidably connected to a dovetail groove 1 on the upper side of the partition 72, and the transverse counterweight 75 is slidably connected to a dovetail groove 2 on the lower side of the partition 72. The electronic level 1 74 is located in the middle of the top wall of the balancing shell 71, and the electronic level 2 76 is located in the middle of the bottom wall of the balancing shell 71. The balancing mechanism 7 also includes a lead screw 77 and a motor 78 (the lead screw 77 is located inside the balancing shell 71, which is enclosed to prevent the exposed parts of the lead screw 77 from contacting the ground). (External environment contact), lead screw 77 is rotatably connected to the inside of dovetail groove 1 and dovetail groove 2 through bearing 1 respectively. The longitudinal counterweight 73 and the transverse counterweight 75 are threadedly connected to the adjacent lead screw 77. Motors 78 are provided on the right and rear sides of the balance shell 71. The output shafts of motors 78 are fixedly connected to the adjacent lead screw 77. The lower side of the balance shell 71 is provided with a control shell 15. The bottom wall of the control shell 15 is provided with a storage battery 16. The middle of the top wall of the control shell 15 is provided with a single-chip microcomputer 17. The input terminal of the single-chip microcomputer 17 is electrically connected to the output terminal of the storage battery 16. The input terminals of motors 78 are electrically connected to the output terminals of single-chip microcomputer 17. Single-chip microcomputer 17 is bidirectionally electrically connected to electronic level 1 74 and electronic level 2 76 respectively. The balancing mechanism 7 also includes a balance Counterweight 79 and balance counterweight 79 are respectively set on the left and front sides of the balance shell 71. The balance counterweight 79 is installed in conjunction with the motor 78. When the loading frame 6 moves the loaded building materials vertically, the microcontroller 17 activates the electronic level 74 to measure the longitudinal tilt angle of the loading frame 6 and transmits the measurement result to the microcontroller 17 in the form of an electrical signal. If the microcontroller 17 detects that the loading frame 6 is tilted vertically, the microcontroller 17 activates the upper motor 78 so that its output shaft drives the upper lead screw 77 to rotate. The upper lead screw 77 drives the longitudinal counterweight 73 to slide along the dovetail groove away from the longitudinal tilt end of the loading frame 6 through the threaded connection, thereby adjusting the overall longitudinal weight distribution of the loading frame 6. This ensures that the load-carrying frame 6 remains horizontal during the vertical movement of the building components. Simultaneously, the microcontroller 17 activates the electronic level 76 to measure the overall lateral tilt angle of the load-carrying frame 6. Based on this measured lateral tilt angle, the microcontroller 17 adjusts the lateral position of the horizontal counterweight 75 using the same principle, ensuring the load-carrying frame 6 remains horizontal during the vertical movement of the building components. This adjustment of the load-carrying frame 6 ensures it remains horizontal during the upward movement of the building components, improving the stability of the hoisting equipment and reducing the probability of components falling off during hoisting. Both the electronic level 74 and the electronic level 76 are powered by a pair of pneumatic instruments that diagonally balance air pressure.The system then uses a detector to measure the generated air pressure and a digital display to indicate whether the surface is level, thus determining the levelness. The working principle involves a photoelectric sensor automatically controlling and displaying the level measurement results by determining the airflow balance position of the air valve. A counterweight 79 balances the weight of the two motors 78 on the balance shell 71, ensuring a uniform weight distribution in the initial state and preventing tilting due to uneven weight distribution. Through transmission and detection components, this device automatically detects and self-adjusts the level of the lifting section of the building, ensuring the building remains level throughout the lifting process. This improves the stability of the lifting operation and is not limited by factors such as screws, making it convenient to use and offering a wide range of lifting stability coverage.

[0021] The working principle of the hoisting equipment for construction provided by this utility model is as follows: When using the hoisting equipment to operate on items during the construction process, the universal wheels 11 facilitate the movement of the hoisting equipment to the designated construction point. Then, the worker activates four electro-hydraulic actuators 13 via the microcontroller 3, causing the telescopic ends of the four electro-hydraulic actuators 13 to drive the corresponding support seats 14 to move down and contact the ground. The support seats 14 increase the overall stability of the base 1 during the use of the hoisting equipment. Subsequently, the worker can activate the electro-hydraulic actuator 10 via the microcontroller 3 according to the construction needs, causing the telescopic ends of the electro-hydraulic actuator 10 to drive the extension slide rod 4 to slide horizontally along the groove of the base 1, thereby adjusting the horizontal position of the hoisting point of the device. In the section, when the device hoists building materials, the electric hoist 5 is started by the microcontroller 3. The electric hoist 5 consists of a motor, transmission mechanism, drum, and hoisting rope. The hoist 5 uses its own hoisting rope to raise and lower the loading frame 6 (by using pulleys 8 and 9, the hoisting ropes passing through the hoisting frame 2 and extension rod 4 are suspended, preventing friction between the hoisting ropes and the hoisting frame 2 or extension rod 4 during use). The loading frame 6 loads the building materials. When the loading frame 6 moves the loaded building materials vertically, the microcontroller 17 activates the electronic level 74 to measure the longitudinal tilt angle of the loading frame 6 and transmits the measurement results via telecommunications. The signal is transmitted to the microcontroller 17. If the microcontroller 17 detects a longitudinal tilt in the loading frame 6, it activates the upper motor 78, causing its output shaft to drive the upper lead screw 77 to rotate. This causes the lead screw 77, through a threaded connection, to slide the longitudinal counterweight 73 along the dovetail groove away from the longitudinally tilted end of the loading frame 6. By adjusting the overall longitudinal weight distribution of the loading frame 6, the loading frame 6 is kept horizontal during the vertical movement of the building materials. Simultaneously, the microcontroller 17 activates the electronic level 76 to measure the overall lateral tilt angle of the loading frame 6. Based on the uploaded lateral tilt angle of the loading frame 6, the microcontroller 17 adjusts the lateral position of the lateral counterweight 75 using the same principle. The system adjusts the load frame 6 to ensure it remains horizontal during the vertical movement of the building components. This adjustment improves the stability of the hoisting equipment and reduces the probability of components falling off during hoisting. Both electronic levels 74 and 76 utilize a pair of pneumatic actuators to diagonally balance air pressure. The generated air pressure is then detected by a detector, and the digital display indicates whether the level is achieved, thus determining the degree of horizontality. The working principle involves a photoelectric sensor automatically controlling and displaying the level measurement results by determining the airflow balance position of the air valve. A counterweight 79 balances the weight of the two motors 78 on the balance shell 71.This ensures that the weight distribution of the balance shell 71 is uniform in its initial state, preventing tilting due to uneven weight distribution.

[0022] It is worth noting that in the above embodiments, the microcontroller 1 (3) and microcontroller 2 (17) can both be MCS-51, the electric hoist 5 can be an MD type electric hoist, the electronic level 1 (74) and electronic level 2 (76) can both be RL-A type electronic levels, the motor 78 can be a 60ST-M00630LBX, the electro-hydraulic actuator 1 (10) can be a DYTZ-1000, and the electro-hydraulic actuator 2 (13) can be a DYZW integral straight micro electro-hydraulic actuator.
