Description

[0002] With the rapid development of photovoltaic power generation, high-quality land resources suitable for large-scale photovoltaic power station construction have also become gradually scarce. Under this background, the construction of photovoltaic projects gradually shifts to mountainous areas and remote offshore areas with large terrain undulations but still rich in light resources. Photovoltaic resources in mountainous areas have significant development potential, especially the solar radiation resources in high-altitude and complex terrain areas are relatively abundant.

Especially for high-drop mountain photovoltaic areas, traditional hoisting equipment cannot adapt to narrow roads and complex terrain in many cases. Due to the narrowness of mountain roads and the difficulty of large cranes to pass through local plots, problems such as the crane being unable to deploy the outriggers and insufficient operating space often occur, which leads to project construction delays, affecting the progress of the construction period and the overall construction quality. In addition, the traditional slide pole hoisting method also cannot meet the hoisting needs of box transformers in high-drop mountain power stations, which makes the construction process of photovoltaic projects more complicated and costly.

DETAILED DESCRIPTION

[0025] The utility model is further explained below in combination with the drawings and examples.

[0026] As Figures 1 to 6 The embodiment of hoisting device for mountainous terrain shown in the drawing includes four parts of load support 1, box transformer platform portal 2, gantry crane crossbeam 3 and electric drive lifting hook 4. The gantry crane crossbeam 3 is arranged along the horizontal direction, the pulley of electric drive lifting hook 4 is arranged on the sliding track of gantry crane crossbeam 3, and electric drive lifting hook 4 slides along the direction of gantry crane crossbeam 3. The left end of gantry crane crossbeam 3 is arranged on the top of load support 1, and the right end of gantry crane crossbeam 3 is arranged on the hanger beam 22 of box transformer platform portal 2. The connection structure between load support 1, box transformer platform portal 2 and gantry crane crossbeam 3 is detachable. The left end of gantry crane crossbeam 3 is connected with the load support strut 12 of load support 1 through fastening bolt or rivet. The right end of gantry crane crossbeam 3 is arranged on the hanger beam 22 through fastening bolt or rivet. The detachable mode can transport four parts of load support 1, box transformer platform portal 2, gantry crane crossbeam 3 and electric drive lifting hook 4 separately in the transportation process. For the complex terrain of mountainous area, the difficulty of transportation is reduced. After transportation to the site, assembly can be realized quickly, and the hoisting device can be obtained.

[0027] The load-bearing support 1, the box transformer platform portal 2, the gantry crane beam 3 and the electrically driven lifting hook 4 of the device can be made of fiber-reinforced resin-based composite material. The fiber-reinforced resin-based composite material has the following advantages: light weight, high strength, the material density is reduced by 4-5 times compared with ordinary carbon steel, but the mechanical strength and corrosion resistance are better; easy to process, convenient to maintain, fiber-reinforced resin-based composite material is suitable for molding of complex structural parts, and has strong corrosion resistance, reducing the difficulty of maintenance; convenient transportation. The load-bearing support 1, the box transformer platform portal 2, the gantry crane beam 3 and the electrically driven lifting hook 4 made of fiber-reinforced resin-based composite material are light in weight, and the transportation and installation of the device are more efficient.

[0028] As for the load-bearing support 1, as shown in Figure 2 , two load-bearing struts 12 intersect to form an inverted V shape, and then form the basic support structure of the load-bearing support 1. The intersection between the load-bearing struts 12 is located at the top, and the intersection is connected to the left end of the gantry crane beam 3 through the beam end and the column head connecting plate 11. In order to strengthen the structural strength of the intersection between the load-bearing struts 12, a load-bearing support and gantry crane beam reinforcing connector 18 is provided to connect the two load-bearing struts 12, preventing the intersection between the two load-bearing struts 12 from separating from each other under heavy pressure and causing the structure of the load-bearing support 1 to collapse. For complex terrain in mountainous areas, the bottom of the load-bearing strut 12 is connected to the height-increased load-bearing support 14 through the connecting sleeve 13, so that the overall height of the load-bearing support 1 is adjusted to adapt to different height requirements. The height-increased load-bearing support 14 is provided with a foundation gasket steel plate 15 at the bottom, which is arranged in the horizontal direction to disperse the pressure and achieve leveling, so that the load-bearing support 1 can better adapt to the complex terrain conditions of mountainous areas and ensure the stable installation of the load-bearing support 1. The load-bearing support laser level 16 is used to detect whether the load-bearing support 1 is horizontal during installation, thereby ensuring the safety of subsequent lifting. The fixed cable load-bearing support fixed cable hanging port 17 is used in cooperation with the fastening cable to prevent the load-bearing support from overturning during lifting.

[0029] As for the box transformer platform portal 2, as shown in Figure 3 and Figure 4 , the hanger beam 22 of the box transformer platform portal 2 is arranged in the horizontal direction, and the right end of the gantry crane beam 3 is arranged on the hanger beam 22 through fastening bolts or rivets. The intersection between the first load-bearing leg 21 and the second load-bearing leg 211 is located at the top, and the top is connected to the bottom of the hanger beam 22, and the connection mode can be fastening bolts or rivets. The hanger beam 22 and the gantry crane beam 3 are perpendicular to each other, and the hanger beam 22 and the two hanger beams 22 are parallel to the load-bearing struts 12, thereby constructing a stress structure that can effectively realize the shaking in the direction of the hanger beam 22. At the same time, as shown in Figure 4As shown, the second load-bearing leg 211 is arranged in the vertical direction, and the first load-bearing leg 21 is arranged obliquely to the horizontal plane. This connection structure can ensure the vertical load-carrying capacity and also has good anti-shaking ability in the direction perpendicular to the gantry beam 22. At this point, the load-bearing strut 12 and the gantry beam 3 are arranged perpendicular to each other, the gantry beam 22 and the load-bearing strut 12 are arranged in parallel, the gantry beam 22 and the gantry beam 3 are arranged vertically, and the gantry beam 22 and the first load-bearing leg 21 and the second load-bearing leg 211 are arranged perpendicular to each other. The above-mentioned structures form a mutual constraint load-carrying structure, which can effectively prevent shaking in the front-rear direction and the left-right direction, greatly improve the stability of the hoisting device and the adaptability to complex mountain terrain, and also facilitate the hoisting device to be arranged on complex mountain terrain. In addition, the above-mentioned structure can also realize flexible selection of the contact point between the bottom and the mountain bottom, that is, by adjusting the orientation of the hoisting device, a more stable placement position can be obtained. The box transformer platform gantry laser level 24 is used to detect the foundation leveling condition to ensure the stability of the box transformer platform gantry 2. The box transformer platform gantry fixed cable hanging port 25 is used to suspend the fastening cable, wherein one end of the cable is fixed to the box transformer platform gantry fixed cable hanging port 25, and the other end of the cable is connected to the surrounding tree trunk or rock to enhance the stability.

[0030] As for the gantry beam 3, as shown in Figure 5 The gantry beam 3 is arranged in the horizontal direction, and the gantry beam 3 includes a truss shaking suppression module 31, a motion control module 32, and a sling limiter and pulley type cable hanger 34. The gantry beam 3 adopts a truss structure, wherein the truss shaking suppression module 31 detects the shaking condition of the beam through a sensor and sends an alarm signal or triggers a sling braking signal to avoid shaking accidents during hoisting. The motion control module 32 adjusts the speed of the sling to avoid the influence of too fast or too slow on the hoisting operation. The sling limiter is used to limit the operating range of the electric drive hook 4 to avoid collision with surrounding objects or exceeding the hoisting area. The pulley type cable hanger 34 is used to suspend the crane cable to prevent safety hazards caused by cable knotting or excessive suspension.

[0031] As for the electric drive hook 4, as shown in Figure 6 The electric drive hook 4 includes a hook transverse movement assembly 41, a hook longitudinal movement assembly 42, and a sling control module 43. The hook transverse movement assembly 41 controls the transverse movement of the sling to ensure hoisting accuracy. The hook longitudinal movement assembly 42 is used to adjust the hoisting height to adapt to the lifting requirements of different box transformers. The sling control module 43 realizes remote control by mobile phone through Bluetooth technology, and the operator can adjust the position and speed of the sling through the mobile phone, greatly improving the operation flexibility and convenience.

[0032] The hoisting device in actual use, first according to the terrain requirements, select the appropriate height of high bearing support 14, splicing bearing support 1, and using the base gasket steel plate 15 and bearing support laser level 16 complete foundation leveling and support installation. Subsequently adjust the installation position of bearing support 1 and box transformer platform gantry 2, let bearing support 1 and box transformer platform gantry 2 can find a better point in mountain ground, ensure the stability of the overall structure after installation. After completing the hoisting operation preparation, start installing gantry crane beam 3 and electric drive hook 4, connect the relevant module, check the stability of the device. In the process of hoisting operation, the operator adjusts the hook position through the lifting tool control module 43, completes the box transformer lifting and transportation. After completing the lifting operation, complete the corresponding safety inspection, check the state of each part, finally disassemble the device and transfer to the next operation area.
