Embodiment 1

[0029] Such as Figure 1-5 As shown, a lifting device for highway construction includes a lifting ring 1 and a mounting seat 2, a bearing seat 3 is fixedly connected to the mounting seat 2, the lower end of the lifting ring 1 is connected to the bearing seat 3, the mounting seat 2 adopts a hollow structure, and the mounting seat 2 The inner rotating connection has two rotating shafts 4 that are symmetrical about the midline, and the two rotating shafts 4 are fixedly connected with booms 5, and multiple sets of equidistantly arranged booms 5 can be installed on the rotating shafts 4, so as to facilitate counterweight The object is hoisted stably, and the two rotating shafts 4 are fixedly connected with the first gear 6 coaxial with it, and the first gear 6 is provided with a damping mechanism for stabilizing the boom 5, and the two booms 5 are close to each other The side walls of the two chute 7 are provided with a chute 7, the chute 7 is slidingly fitted with a slider 8, the ...

Embodiment 2

[0040] Such as figure 2 and 5 As shown, the difference between this embodiment and Embodiment 1 is that multiple groups of conductive coils 24 are embedded in the boom 5, the winding direction of the conductive coils 24 extends along the axial direction of the screw rod 19, and the slider 8 is close to the conductive wires. One end of the coil 24 is made of magnetic material. When the slider 8 slides in the chute 7, the conductive coil 24 continuously cuts the magnetic field lines of the slider 8 to generate an induced current.

[0041] Further, two electrode plates 22 are fixedly connected to the side walls of the upper end and the lower end of the damping box 10, and the two electrode plates 22 are arranged facing each other. When the induced current is generated, the two electrode plates 22 can be charged, so that a magnetic field is generated between the two electrode plates 22, and the electrode plate 22 is covered with a shielding cover 23, and the shielding cover 23 p...

Abstract

The invention belongs to the field of lifting devices, and particularly relates to a lifting device for highway construction, which comprises a lifting ring and a mounting seat, the mounting seat is fixedly connected with a bearing seat, the lower end of the lifting ring is connected with the bearing seat, the mounting seat is of a hollow structure, and two rotating shafts symmetrical about the center line of the mounting seat are rotatably connected in the mounting seat. The two rotating shafts are fixedly connected with suspension arms, the two rotating shafts are fixedly connected with first gears which are coaxial with the two rotating shafts, the first gears are provided with damping mechanisms used for stabilizing the suspension arms, the side walls, close to each other, of the two suspension arms are provided with sliding grooves, and sliding blocks are arranged in the sliding grooves in a sliding fit mode. When the heavy object swings, the damping plate reciprocates in the damping box, stabilization of the heavy object is achieved through the damping liquid, the heavy object is periodically lifted in the swinging process, kinetic energy is converted into gravitational potential energy to be consumed, and the swinging amplitude of the heavy object can be effectively reduced till swinging is completely stopped.

Description

technical field [0001] The invention belongs to the field of lifting devices, in particular to a lifting device for road construction. Background technique [0002] In highway construction, materials, equipment, and operations are the main links to ensure product quality. Among them, lifting devices are indispensable construction equipment, mainly used for handling and stacking construction materials. [0003] After retrieval, the National Patent Publication No. CN102530708B discloses a lifting device, the lifting device includes a suspension ring, the lower end of the suspension ring is connected with a bearing seat, the lower end surface of the bearing seat is fixedly connected with the outer ring of the bearing, and the bearing The center line of the housing is on the same line as the center line of the bearing housing. The inner ring of the bearing is tightly fitted on the journal, and the journal extends downward to the outside of the inner ring. It also includes left...
