DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figures 1 to 8 As shown, the utility model provides a building material lifting device for construction engineering with a protective device, including a bracket 1, a side of the bracket 1 is fixedly connected to a transmission wheel 11, a side of the bracket 1 away from the transmission wheel 11 is fixedly connected to a connecting rod 12, and an end of the connecting rod 12 away from the bracket 1 is fixedly connected to a pulley, the bracket 1 is located at the bottom of the transmission wheel 11 and is fixedly connected to a support plate 13, a winding wheel 14 is provided on the support plate 13, one end of the winding wheel 14 is fixedly installed with a servo motor, the servo motor is fixedly connected to the top of the support plate 13, a control unit 2 is fixedly provided on the bracket 1, a steel rope 3 is wound around the winding wheel 14, the steel rope 3 transmits power through the transmission wheel 11 and the pulley, a pallet 4 is hoisted at one end of the steel rope 3 away from the winding wheel 14, and the top of the pallet 4 is symmetrically fixedly connected to lifting rings 41 on both sides, the lifting rings 41 are fixedly connected to the steel rope 3, and a balancing mechanism 5 for adjusting the balance of the pallet 4 is provided at the bottom of the pallet 4; the balancing mechanism 5 includes two sliding The two slides 51 are distributed on both symmetrical sides of the tray 4. A moving block 52 is slidably connected to the slide 51, and a screw 53 is screwed on the moving block 52. Both ends of the slide 51 are fixedly connected to a closed plate, and the screw 53 passes through the closed plate and is rotatably connected to the closed plate. One end of the screw 53 is fixedly connected to a control motor 54, and the control motor 54 is fixedly connected to the closed plate. The cross-sections of the slide 51 and the moving block 52 are both T-shaped. Two symmetrical rubber strips 511 are fixedly connected to the inner wall of the slide 51. The bottom of the moving block 52 is fixedly connected to a mounting plate 55. A gravity block 57 is installed at the bottom of the mounting plate 55. A clamping assembly 56 is provided on the mounting plate 55. Gravity sensors 42 are fixedly provided at the four internal edges of the tray 4. The input end of the control unit 2 is connected to the gravity sensor 42, and the output end of the control unit 2 is connected to the control motor 54 and the rotating motor 564. The control unit 2 is bidirectionally connected with a storage module.

[0028] The above solution is adopted: when in use, the gravity in various directions inside the pallet is detected by the gravity sensor 42 inside the pallet. When it is detected that the gravity on one side is larger, the detection result is transmitted to the control unit 2 for comparison with the threshold value in the internal storage module. When the gravity exceeds the range, it means that one side of the pallet 4 is overweight. At this time, the position of the gravity block 57 needs to be adjusted to achieve the balancing effect. The control unit 2 controls the control motor 54 to lift, drive the screw 53 to rotate, and then drive the moving block 52 to slide inside the slide 51, so that it slides away from the side with heavier gravity, so that the pallet 4 remains in a balanced state, and the control motors 54 on both sides can be adjusted separately.

[0029] like Figures 1 to 8 As shown, the clamping assembly 56 includes two clamping blocks 561, and the two clamping blocks 561 are symmetrically distributed on both sides of the mounting plate 55. Two racks 562 are fixedly connected to the top of the two clamping blocks 561. Gears 563 are engaged at the teeth of the two racks 562. The gear 563 is located at the center of the mounting plate 55.

An accommodating cavity 521 is provided on the moving block 52. The rotating motor 564 is fixedly installed inside the accommodating cavity 521. A slot 551 is provided at the bottom of the mounting plate 55. A clamping block is fixedly connected to the top of the rack 562, and the clamping block is slidably engaged with the slot 551.

[0030] The above solution is adopted: by utilizing the clamping assembly 56, it is convenient to replace the gravity block 57 according to the gravity of different lifting building materials, and utilize the rotating motor 564 to drive the rack 562 to move toward each other along the gear 563, so as to achieve the effect of driving the clamping block 561 to open and close, so as to facilitate the clamping of gravity blocks 57 of different sizes.

[0031] The working principle and usage process of the present invention are as follows: when using the present invention, first place the building materials and tools that need to be lifted on the bottom tray 4, and then use the servo motor to drive the winding wheel 14 to rotate, and then drive the steel rope 3 to transmit along the transmission wheel 11 and the pulley to drive the tray 4 to lift. During the lifting process, in order to avoid the building materials placed inside the tray 4 moving inside the tray 4 and causing the tray 4 to be unstable and tilted, causing the internal objects to fall and injure people, the balance adjustment of the tray 4 can be achieved by using the balancing mechanism 5. Through the coordinated use of the gravity sensor 42 and the gravity block 57, the balancing effect is achieved to keep the tray 4 in a balanced state, and the clamping assembly can be used to replace the gravity block 57.
