[0039] Sensor 5: It is arranged at the end of the winding mechanism 4 and is used to monitor the weight of the hanging object (i.e., the steel structure). The sensor 5 can detect the weight change in real time and transmit the signal to the alarm mechanism 6.

[0040] Alarm mechanism 6: connected to sensor 5 and capable of receiving signals from sensor 5. When the weight exceeds a set threshold, the alarm mechanism 6 will sound an alarm to remind the operator to take timely measures.

[0041] Center of gravity adjustment mechanism 8 (reference Figure 2 and Figure 4 ): It is arranged on the other side wall of the main support rod 1 and is used to adjust the center of gravity of the device during the lifting process. The center of gravity adjustment mechanism 8 is composed of a hydraulic rod 801, a counterweight block 802, a slide groove 804, an electromagnet 805, a magnetic block 806 and a folding sealing cover 803. The height of the counterweight block 802 is adjusted by the coordinated action of the hydraulic rod 801 and the counterweight block 802, and after the adjustment, the electromagnet 805 is energized to make it adsorb the magnetic block 806, so that the counterweight block 802 can be connected to the main support rod 1 as a whole, so that the center of gravity of the device can be accurately adjusted.

[0042] In addition, the hoisting safety device in the steel structure construction also has the following characteristics:

[0043] The steel wire rope 404 is overlapped on the guide wheel 7 in the guide seat 3, which can effectively reduce the friction force generated by the steel wire rope 404 during the movement.

[0044] The sensor 5 is a weight sensor 5 and is arranged on the hook 405. Such a design can more accurately monitor the actual load of the hanging object.

[0045] The alarm mechanism 6 has a built-in main control chip and an alarm 601, which can respond quickly and emit obvious sound or light signals to remind the operator (refer to Figure 3 ).

Mounting holes 10 are provided at the four corners of the upper end of the base 9 to facilitate the installation and fixing of the device by anchor bolts.

[0047] The main support rod 1, the transverse connecting rod 2 and the hook 405 are all made of high-strength materials and can withstand large loads and external forces.

[0048] In a specific embodiment, the present invention discloses a hoisting safety device for steel structure construction, which includes a winding mechanism 4, a center of gravity adjustment mechanism 8, a sensor 5 and an alarm mechanism 6.

The mechanism 8 is composed of a hydraulic rod 801, a counterweight 802, a slide 804, an electromagnet 805, a magnet 806 and a folding sealing cover 803. The hydraulic rod 801 is fixed on the main support rod 1, the output end of the hydraulic rod 801 is connected to the counterweight 802, the slide 804 is formed on the main support rod 1, the counterweight 802 is slidably connected to the slide 804, the electromagnet 805 is fixed in the slide 804, the magnet 806 is embedded in a side wall of the counterweight 802, and the folding sealing cover 803 is fixed between the counterweight 802 and the slide 804. The sensor 5 is a weight sensor 5, and is arranged on the hook 405. The alarm mechanism 6 has a main control chip and an alarm 601 built in.

[0049] In one embodiment, the winding mechanism 4 can be fixed on the main support rod 1 through the support 401, the output shaft of the motor 402 is connected to the winding shaft 403, and the wire rope 404 is wound on the winding shaft 403. In this way, during the lifting process, the motor 402 can control the rotation of the winding shaft 403, thereby realizing the tightening and loosening of the wire rope 404.

[0050] The wire rope 404 can be overlapped on the guide wheel 7 in the guide seat 3 by passing the wire rope 404 through the guide seat 3 and overlapping it on the guide wheel 7. In this way, during the lifting process, the guide wheel 7 can guide the movement direction of the wire rope 404 to increase the safety of the lifting.

[0051] The center of gravity adjustment mechanism 8 can be fixed on the main support rod 1 through a hydraulic rod 801, and the output end of the hydraulic rod 801 is connected to the counterweight block 802, and the counterweight block 802 can slide in the slide groove 804. In this way, during the hoisting process, the hydraulic rod 801 can be telescopically adjusted as needed to adjust the height of the counterweight block 802 and after the adjustment, the electromagnet 805 is energized to make it adsorb the magnetic block 806, so that the counterweight block 802 can be connected to the main support rod 1 as a whole, and the center of gravity position of the main support rod 1 is changed by the counterweight block 802 to maintain balance.

[0052] The weight sensor 5 can be arranged on the hook 405 and can measure the weight of the object supported by the hook 405. When the weight exceeds the set range, the sensor 5 will send a signal to the alarm mechanism to trigger the alarm 601 to sound an alarm.

[0053] The working process of the hoisting safety device in the steel structure construction of the utility model is as follows:

[0054] First, fix the main support rod at the position where it needs to be hoisted and ensure its stability. The transverse connecting rod is set at the upper end of the main support rod to connect other parts.

[0055] Then, multiple guide seats are installed on the top of the transverse connecting rod and the guide seat with a built-in guide wheel at one end to ensure that the wire rope can be correctly guided during the lifting process.

[0056] Next, install the winding mechanism on the upper end of the other side wall of the main support rod. The winding mechanism consists of a support, a motor, a winding shaft, a wire rope and a hook. The support is fixed on the main support rod, the output shaft of the motor is fixedly connected to the winding shaft, and the wire rope is wound around the winding shaft.

[0057] At the same time, a sensor is set at the end of the winding mechanism to monitor the weight of the hoisted steel structure. The sensor is connected to the alarm mechanism and can receive the signal sent by the sensor. When the weight exceeds the set threshold, the alarm mechanism will sound an alarm.

[0058] In order to ensure the stability of the equipment during the lifting process, a gravity center adjustment mechanism is also set up, which consists of a hydraulic rod, a counterweight, a slide, an electromagnet, a magnetic block and a folding sealing cover. The hydraulic rod is fixed on the main support rod, and the output end of the hydraulic rod is fixedly connected to the counterweight. The slide is formed on the main support rod, and the counterweight can be connected to the slide by sliding.

[0059] The electromagnet is fixed in the slide slot, the magnetic block is embedded in a side wall of the counterweight block, and the folding sealing cover is fixed between the counterweight block and the slide slot.

[0060] Finally, a base is fixed at the bottom of the main support pole to increase the contact area between the main support pole and the ground and ensure its stability. There are mounting holes at the four corners of the base to facilitate the installation and fixing of the device using anchor bolts.

[0061] During the entire lifting process, the steel structure is connected to the winding mechanism through hooks and wire ropes, and the lifting operation is carried out under the guidance of the guide wheel. The sensor will continuously monitor the weight of the hoisted steel structure and transmit the signal to the alarm mechanism. When the set threshold is exceeded, the alarm mechanism will sound an alarm to remind the operator to pay attention to safety. At the same time, the stability of the equipment is ensured by adjusting the center of gravity adjustment mechanism during the lifting process, that is, the height of the counterweight block is adjusted through the coordinated action of the hydraulic rod and the counterweight block, and after the adjustment, the electromagnet is energized to make it adsorb the magnetic block, so that the counterweight block can be connected to the main support rod as a whole, thereby realizing precise adjustment of the center of gravity of the device.
