Description

Technical Field

[0001] The utility model relates to the technical field of hoisting equipment, and more specifically, to a hoisting device for plateau photovoltaic construction. Background Art

[0002] During the construction of plateau photovoltaic power generation facilities, hoisting devices are used when some materials are relatively heavy or the installation height is relatively high. When the existing hoisting devices are hoisting, the materials are generally fixed by ropes, and then the hooks of the hoisting devices are hooked on the ropes, and the materials are moved by the hoisting devices to carry the materials.

[0003] At present, the Chinese patent with the publication number CN218201742U discloses a hoisting device, which includes a pile body, a short column and a long column. The short column and the long column are respectively arranged on both sides of the pile body. The long column and the short column are connected by a hoop. A cantilever beam is connected to the long column. The cantilever beam is horizontally arranged. A hoisting assembly is installed on the cantilever beam. The hoisting assembly can move on the cantilever beam. A limiting structure for restricting the moving range of the hoisting assembly is arranged on the cantilever beam. The top height of the long column is higher than that of the pile body. A positioning anti-falling block is arranged on the long column, and the positioning anti-falling block abuts against the top surface of the pile body.

[0004] The above patent points out the defects of the existing technology: in the actual construction process, there will always be some areas with poor working conditions, and it is necessary to rely on manpower to hoist the base of the photovoltaic bracket and other components to the top of the pile for installation. However, it is difficult to implement by manpower. Relying on manual lifting, on the one hand, the efficiency is extremely low, a large number of personnel are required, and the economy is poor; on the other hand, the safety factor is relatively low, the cooperation degree of workers is required to be relatively high, and safety accidents are prone to occur. Although this hoisting device solves the above deficiencies, the following new defects have emerged: 1. When the existing hoisting device uses a rope hook to lift, it will cause the material to shake violently in the air, resulting in a risk of the material falling; 2. It is very difficult to ensure the stability of the hoisting device during the hoisting process, and during the hoisting process, due to the movement, vibration is easily generated, which is likely to affect the hoisted heavy object.

[0027] Embodiment:

[0028] As Figures 1-3 shown, the present utility model provides a high-altitude photovoltaic construction hoisting device, which includes a vertically arranged hoisting device main body 1. The lower end of the hoisting device main body 1 is fixedly connected to a fixed platform 2 located below it, and the upper end is connected to a horizontally arranged lifting arm 3 located on one side of it; on the side of the lifting arm 3 away from the hoisting device main body 1, an installation block 4 and a hook 5 are fixedly installed. The hook 5 is located at the outermost bottom end of the lifting arm 3 and extends vertically downward. The installation block 4 is rectangular and there are two in total. These two installation blocks 4 are respectively arranged on both sides in the direction perpendicular to the axis of the lifting arm. A vacuum suction cup 6 is fixedly installed corresponding to the lower end of each installation block 4. An air vent 7 is opened in the middle of the vacuum suction cup 6. A first connecting pipe 8 is connected between the air vents 7 of the two vacuum suction cups 6 (that is, the hook 5 is located outside the first connecting pipe 8 to facilitate hooking high-altitude photovoltaic materials), and the air vent 7 on one of the vacuum suction cups 6 is also connected to one end of a second connecting pipe 9. The other end of the second connecting pipe 9 is connected to the suction port 11 of an air extraction pump 10. The air extraction pump 10 is installed on the top of the fixed platform 2. An exhaust port 12 is also provided on the air extraction pump 10. Generally, the suction port 11 and the exhaust port 12 on the air extraction pump 10 are arranged side by side.

[0029] The utility model evacuates the air in the vacuum suction cup 6 by turning on the air extraction pump 10, so that the high-altitude photovoltaic material is sucked and fixed and lifted by the lifting hook 5, which plays a role in reducing violent shaking during the hoisting process of the high-altitude photovoltaic material. The exhaust port 12 on the air extraction pump 10 discharges the extracted air, so that the internal air of the vacuum suction cup 6 is evacuated.

[0030] A shock absorption mechanism is installed at the lower end of the fixed table 2 in the utility model. In a further specific embodiment, as Figure 4 shown, the shock absorption mechanism includes a support column 13 fixedly connected to the bottom end of the fixed table. The bottom end of the support column 13 is inserted into a shock absorption plate 14 located below it; a support rod 15 is hinged on the outer wall of the column body of the support column 13. A groove 16 extending away from the support column is correspondingly opened at the position corresponding to the support rod 15 on the upper plate surface of the shock absorption plate. A fixed rod 17 is fixedly installed in the groove 16. A spring 18 is sleeved outside the fixed rod 17. One end of the spring 18 close to the support column 13 is connected with a sliding block 19. The sliding block 19 is sleeved and slidably installed on the fixed rod 17 (that is, the sliding block 19 can move along the axial direction of the fixed rod), and the end of the support rod 15 away from the support column 13 is hinged to the corresponding sliding block 19 below.

[0031] During the hoisting process, the shaking force generated by the hoisting device main body 1 is applied to the support column 13. The support column 13 transmits the force to the support rod 15 and causes the sliding block 19 to be squeezed towards the spring 18 on the fixed rod 17, playing the effect of buffering the acting force. Moreover, the elastic performance of the spring 18 itself can generate reciprocating motion to buffer and damp the acting force.

[0032] Furthermore, in order to facilitate the movement of the device, universal walking wheels 20 with brakes are installed at the four corners of the bottom end of the shock absorption plate 14.

[0033] In one embodiment, the number of the support rods 15 is two. The two support rods 15 are distributed relatively on the support column 13, and the two support rods 15 are respectively arranged on one side close to the lifting hook and one side far from the lifting hook to play a shock absorption role when the boom 3 and the fixed table 2 shake back and forth.

[0034] In another embodiment, the number of the support rods 15 is four or eight. Several support rods 15 are circumferentially and equidistantly hinged on the outer wall of the column body of the support column 13 to achieve shock absorption in all directions of structures such as the boom 3 and the fixed table 2.

[0035] In a further specific embodiment, the boom 3 is hinged to the upper end of the hoisting device main body 1. An expansion link mechanism 21 is installed on the outer wall of the fixing platform 2 on the side close to the boom. The lower expansion link main body of the expansion link mechanism 21 is fixedly connected to the fixing platform 2, and the upper expansion link end of the expansion link mechanism 21 is hinged to the hinge seat 22 on the lower bottom surface of the boom. The height of the boom 3 is controlled by controlling the telescopic length of the expansion link end. At the same time, the hinge seat 22 is axially slidably installed on the lower bottom surface of the boom 3.

[0036] Of course, in practice, if there is no need to adjust the height of the boom 3, the boom 3 can be directly fixedly connected to the upper end of the hoisting device main body 1, and in this case, the expansion link mechanism can no longer be installed.

[0037] In a further specific embodiment, in order to facilitate the movement operation, a handle 23 is also installed on the side of the fixing platform 2 away from the hook 5.

[0038] The working principle of the present utility model:

[0039] When in use, first, the air pump 10 is started to pump out the air in the vacuum suction cup 6 through the second connecting pipe 9 and the first connecting pipe 8, so as to suck and fix the plateau photovoltaic material and lift it by the hook 5, effectively reducing the violent shaking of the plateau photovoltaic material when it is lifted. At the same time, the exhaust port 12 on the air pump 10 will discharge the pumped air, so that the air inside the vacuum suction cup 6 is evacuated, playing a better fixing role for the plateau photovoltaic material; during the hoisting process, the construction hoisting device will also shake. At this time, the shaking force will act on the support column 13, and the support column 13 will transmit the force to the support rod 15, and make the sliding block 19 squeeze towards the spring side on the fixed rod 17, playing an effect of buffering the acting force, and the elastic performance of the spring 18 itself can generate reciprocating motion to buffer and damp the acting force, which is beneficial to extending the service life of the plateau photovoltaic construction hoisting device.
