[0024] The embodiment of the present application provides a hoisting device for use in infrastructure construction of a thermal power plant, which is used to improve the problem of collision damage to equipment caused by the movement of equipment in the hoisting device during use of the existing hoisting device.

[0025] like Figure 1 As shown, in some embodiments, a hoisting device for infrastructure construction of a thermal power plant includes: an installation platform 1, a hoisting machine 2 and a hanging basket 3. The installation platform 1 is arranged on a fixed base 41. The hoisting machine 2 is arranged on the installation platform 1, and the hoisting machine 2 has a hoisting device 21 and a hoisting rope 22, and the hoisting device 21 is used to retract and release the hoisting rope 22. The hanging basket 3 is connected to the hoisting rope 22, and the hanging basket 3 is used to rise and fall when the hoisting device 21 retracts and releases the hoisting rope 22 for hoisting. Specifically, when the hoisting device 21 releases the hoisting rope 22, the hoisting machine 2 can control the hanging basket 3 to fall, and when the hoisting device 21 reels the hoisting rope 22, the hoisting machine 2 can control the hanging basket 3 to rise, and the equipment can be hoisted by controlling the lifting of the hanging basket 3.

[0026] like Figure 1As shown, in some embodiments, the hoisting machine 2 has a support arm 23, and the support arm 23 is used to support the hoisting rope 22 to make it fall from a high place, so that the hoisting rope 22 can drive the hanging basket 3 to rise when being reeled in by the hoisting device 21.

[0027] In some embodiments, the support arm 23 can be extended. During use, when the support arm 23 is extended to different lengths, the hoisting rope 22 can fall from different heights, so that the maximum lifting height of the hanging basket 3 can be adjusted. Of course, the support arm 23 can also adjust the maximum lifting height of the hanging basket 3 by changing its own inclination angle. For example, Figure 1 As shown, the hoisting machine 2 has a power push rod 24, which can be an electric push rod or a hydraulic push rod. The hoisting machine 2 can push the support arm 23 through the power push rod 24 to change its tilt angle.

[0028] like Figure 2 As shown, in some embodiments, a buffer block 31 is provided at the bottom of the hanging basket 3. During use, when the hanging basket 3 falls to the ground, the buffer block 31 can buffer the hanging basket 3.

[0029] like Figure 2 As shown, in some embodiments, a lifting lug 32 is provided on the top of the hanging basket 3. During use, the hanging basket 3 can be connected to the hoisting rope 22 through the lifting lug 32. In a specific setting, there can be multiple lifting lugs 32, and the multiple lifting lugs 32 are respectively arranged around the hanging basket 3.

[0030] like Figure 1 and Figure 2 As shown, in some embodiments, a protective assembly is provided in the hanging basket 3, and the protective assembly includes two protective plates 33 and two buffer mechanisms 34. The protective plates 33 are arranged in parallel with each other and can move laterally relative to the hanging basket 3. The protective plates 33 are used to clamp the hoisted object to limit the longitudinal movement of the hoisted object relative to the hanging basket 3. The buffer mechanism 34 is arranged between the protective plates 33 and the hanging basket 3, and the buffer mechanism 34 is used to buffer when the protective plates 33 move laterally relative to the hanging basket 3. Specifically, when the hoisted object is loaded into the hanging basket 3, it is specifically placed between the two protective plates 33. The two protective plates 33 can limit the longitudinal movement of the hoisted object relative to the hanging basket 3, so that the hoisted object can be prevented from colliding with the longitudinal sides of the hanging basket 3. In addition, when the hoisted object moves laterally relative to the hanging basket 3, the protective plates 33 can move together with the hoisted object under the action of friction. During the movement, the buffer mechanism 34 can buffer the protective plates 33, and can also buffer the hoisted object. In general, the protective component can improve the problem of collision damage to the equipment caused by the movement of the equipment in the sling during use of the existing lifting device.

[0031] like Figure 2As shown, in some embodiments, the buffer mechanism 34 includes a guide rod 341, a moving seat 342 and an elastic member 343. The guide rod 341 is fixedly arranged along the lateral direction of the hanging basket 3. The moving seat 342 is slidably arranged on the guide rod 341 and connected to the protective plate 33. The elastic member 343 is arranged between the moving seat 342 and the hanging basket 3, and the elastic member 343 is used to accumulate elastic potential energy when the moving seat 342 slides. Specifically, the sliding direction of the moving seat 342 is consistent with the moving direction of the protective plate 33. When the protective plate 33 moves with the hoisted object, the protective plate 33 can drive the moving seat 342 to slide along the guide rod 341. The moving seat 342 acts on the elastic member 343 during the sliding process, so that the elastic member 343 converts kinetic energy into elastic potential energy, thereby achieving buffering of the protective plate 33 and the hoisted object.

[0032] In some embodiments, the elastic member 343 is a spring, and the elastic member 343 is sleeved on the guide rod 341. This arrangement can prevent the elastic member 343 from bending and affecting the buffering effect of the buffer mechanism 34, thereby improving the reliability of the structure.

[0033] In some embodiments, elastic members 343 are respectively provided at both ends of the movable seat 342. Specifically, elastic members 343 are respectively provided between the movable seat 342 and the two side walls of the hanging basket 3. When the movable seat 342 slides, one of the elastic members 343 is contracted to accumulate elastic potential energy, and the other elastic member 343 is stretched to accumulate elastic potential energy. This arrangement can improve the buffering effect of the buffer mechanism 34. In this regard, the embodiments of the present application do not make any limitation.

[0034] like Figure 2 As shown, in some embodiments, the number of the movable seats 342 is two, and elastic members 343 are respectively arranged between the two movable seats 342 and the two side walls of the hanging basket 3. Specifically, an elastic member 343 is arranged between one of the movable seats 342 and the left side wall of the hanging basket 3, and an elastic member 343 is arranged between the other movable seat 342 and the right side wall of the hanging basket 3. Such an arrangement can also improve the buffering effect of the buffer mechanism 34. In addition, since the number of the movable seats 342 is two, in the specific arrangement, the two movable seats 342 can be respectively connected to the two ends of the protective plate 33, which increases the connection points between the buffer mechanism 34 and the protective plate 33, can disperse the force on the protective plate 33, and is conducive to improving the reliability of the protective plate 33.

[0035] like Figure 2As shown, in some embodiments, the buffer mechanism 34 further includes a connecting rod 344, the movable seat 342 and the protective plate 33 are connected by the connecting rod 344, and the movable seat 342 and the protective plate 33 are respectively detachably connected to the connecting rod 344. During use, by replacing the connecting rod 344 of different lengths, the distance between the two protective plates 33 can be changed, so that the protective assembly can be suitable for protecting equipment of different sizes.

[0036] like Figure 2 As shown, in some embodiments, the buffer mechanism 34 further includes a mounting seat 345, the mounting seat 345 is arranged in the hanging basket 3, and the guide rod 341 is installed on the mounting seat 345. Specifically, the other parts of the buffer mechanism 34 are all arranged on the mounting seat 345, so that the buffer mechanism 34 can be assembled into the hanging basket 3 after pre-assembly, so that the buffer mechanism 34 can be easily assembled, which is conducive to improving assembly efficiency.

[0037] like Figure 2 As shown, in some embodiments, the mounting seat 345 is provided with a slide groove, and the movable seat 342 is located in the slide groove and slides with the slide groove. For example, a slide groove is dug on the side of the mounting seat 345, the guide rod 341 is installed in the slide groove, the movable seat 342 is sleeved on the guide rod 341 and is located in the slide groove, and the movable seat 342 slides with the slide groove. During use, the slide groove can limit the movable seat 342 from rotating relative to the guide rod 341, so that the protective plate 33 can be prevented from rotating relative to the guide rod 341 during the hoisting process, thereby limiting the up and down movement of the hoisted object in the hanging basket 3, which is conducive to improving the protective effect of the protective component.

[0038] like Figure 1 As shown, in some embodiments, the hoisting device further includes: a hook 4, the hook 4 is arranged on the hoisting rope 22, and the hoisting rope 22 is connected to the hanging basket 3 through the hook 4. Specifically, the hook 4 is connected to the hanging basket 3 (the lifting ear 32) through a rope.

[0039] like Figure 3 As shown, in some embodiments, the hook 4 includes a base 41, a hook body 42 and a driving mechanism 43. The base 41 is connected to the hoisting rope 22. The hook body 42 is arranged on the base 41 and is used to connect the hanging basket 3, and the hook body 42 can rotate circumferentially relative to the base 41. Specifically, the upper end of the hook body 42 has a rotating shaft 421, and the rotating shaft 421 is rotatably arranged on the base 41, so that the hook body 42 can rotate circumferentially relative to the base 41. The driving mechanism 43 is arranged on the base 41 and is used to drive the hook body 42 to rotate circumferentially relative to the base 41. Specifically, during the hoisting process, the driving mechanism 43 can drive the hook body 42 to rotate to change the direction and angle of the hanging basket 3 and the hoisted object, so as to facilitate the relevant unloading device to pick up and unload the hoisted object.

[0040] like Figure 3As shown, in some embodiments, the driving mechanism 43 includes a motor 431, a first gear 432 and a second gear 433. The motor 431 is disposed on the base 41. The first gear 432 is connected to the driving shaft of the motor 431 (through a coupling). The second gear 433 is connected to the hook body 42 and meshes with the first gear 432. Specifically, the second gear 433 is sleeved outside the rotating shaft 421 of the hook body 42 and meshes with the first gear 432. During use, the motor 431 is started, and the driving shaft of the motor 431 can drive the first gear 432 to rotate. When the first gear 432 rotates, the second gear 433 can be driven to rotate. When the second gear 433 rotates, the rotating shaft 421 can be driven to rotate, so that the hook body 42 can be driven to rotate relative to the base 41 in a circumferential direction to change the direction and angle of the hanging basket 3 and the hoisted object.

[0041] like Figure 3 As shown, in some embodiments, the base 41 is a box body, the first gear 432 and the second gear 432 are arranged inside the box body, and the motor 431 is arranged on the outer wall of the box body and connected to the first gear 432. In this way, dust can be prevented from accumulating on the surface of the device and affecting the driving effect, which is conducive to improving the reliability of the device.

[0042] According to the above scheme, in the hoisting device for the construction of the thermal power plant infrastructure of the embodiment of the present application, when the hoisted object is loaded into the hanging basket 3, it is specifically placed between the two protective plates 33. The two protective plates 33 can limit the longitudinal movement of the hoisted object relative to the hanging basket 3, so as to prevent the hoisted object from colliding with the longitudinal sides of the hanging basket 3. In addition, when the hoisted object moves laterally relative to the hanging basket 3, the protective plates 33 can move together with the hoisted object under the action of friction. During the movement, the buffer mechanism 34 can buffer the protective plates 33 and the hoisted object. In general, the protective assembly can improve the problem of collision damage to the equipment caused by the movement of the equipment in the sling during use of the existing hoisting device.

[0043] One or more embodiments of this specification are intended to cover all such substitutions, modifications and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of one or more embodiments of this specification should be included in the scope of protection of this application.

[0044] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
