Description

Technical Field

[0001] The invention belongs to the technical field of construction elevators, and in particular relates to an oblique and vertical segmented construction elevator device for an intercooling tower. Background Art

[0002] The built-in skin construction method is generally used for large intercooling towers, which means that the steel structure frame of the intercooling tower is located outside the skin, and reinforcement rings are also provided on the periphery of the steel structure frame for reinforcement. The main shape of this large intercooling tower is generally divided into a lower cone shape and an upper cylindrical shape.

[0003] During the construction process, a lifting device needs to be set up to facilitate the lifting of construction workers. Due to the special shape of this type of intercooler tower, a two-section lifting device with an inclined track and a straight track needs to be set up. In the prior art, two independent elevator cabins and tracks are generally set up. During the transfer process, construction workers need to replace the elevator cabins. When transporting construction workers, especially when construction workers carry heavy tools and materials, the transfer process leads to poor transportation efficiency, and the space on the reinforced ring is small, making it difficult to build a transfer waiting space. Summary of the invention

[0004] The purpose of the present invention is to provide an inclined and vertical segmented construction lifting device for an intercooling tower in order to solve the above-mentioned problem.

[0005] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0006] A vertical and oblique segmented construction lifting device for an intercooling tower comprises a lifting cabin, a straight track connected to the intercooling tower, an oblique track, and a conversion mechanism arranged between the straight track and the oblique track, wherein the lifting cabin comprises a cabin body and a climbing device rotatably arranged on the cabin body and corresponding to each track, the climbing device is further provided with a pair of locking grooves, which are used to dock with a locking driving member arranged on the cabin body, so that the cabin body is kept vertically fixed before and after the climbing device track is converted, and the conversion mechanism comprises a conversion track, which is used to convert and dock with the straight track and the oblique track;

[0007] It also includes a transfer mechanism, which is used to support the cabin when the climbing device track is converted.

[0008] As a further optimization scheme of the present invention, the straight track and the inclined track are fixedly connected to the steel structure of the intercooling tower through a reinforcing component. The reinforcing component extends from the tower body of the intercooling tower to support the reinforced track. Reinforcing components of different structures can also be selected according to the spacing size.

[0009] As a further optimization scheme of the present invention, the conversion mechanism includes a driving part arranged on the reinforcement ring, and a reduction device is arranged at the output end of the driving part, and a connecting shaft connected to the conversion track is arranged at the output end of the reduction device, and the connecting shaft is provided with an angle sensing device and a locking device. The conversion mechanism needs to have the ability to undertake the elevator cabin, so its connecting shaft needs to be equipped with a stabilizing device so that the conversion track can withstand the climbing of the elevator cabin, and the driving part drives the connecting shaft to rotate through the reduction device.

[0010] As a further optimization scheme of the present invention, the climbing device is provided with a reduction drive, drive teeth, guide wheels and a safety locking device, wherein racks meshing with the drive teeth are provided on the straight track and the inclined track. The climbing device is a prior art, which includes one or more reduction drives, and climbs on the track through the structure of gears and tooth grooves. Different from the prior art, the climbing device and the cabin in this scheme can rotate so that the cabin can maintain a vertical orientation when the climbing device corresponds to tracks of different angles.

[0011] As a further optimization scheme of the present invention, the climbing device is rotatably connected to the cabin through a rotating shaft. When the climbing device performs angle conversion, the rotating shaft and the connecting shaft are located on the same axis. By arranging the rotating shaft and the connecting shaft to be located on the same axis, the track switching is performed when the cabin is fixed. When the cabin is supported by the transfer mechanism, the cabin is fixed by its own weight. At this time, driving the climbing device to turn through the conversion mechanism will not affect the cabin or cause the cabin to shake.

[0012] As a further optimization scheme of the present invention, the transfer mechanism includes a protective wall mounted on a reinforcement ring, a flange is arranged on the inner side of the protective wall, a base is arranged inside the cabin, telescopic feet which can be extended to both sides are arranged on the base, and the telescopic feet are used to straddle the surface of the flange to support the cabin. When the cabin is lifted into the protective wall, the telescopic feet are extended to straddle the flange, and the cabin is supported and fixed by its own weight, so that the passengers in the cabin will not be affected during the track switching process.

[0013] As a further optimization solution of the present invention, the telescopic foot is electrically driven to achieve telescopic movement. In this solution, the telescopic foot is realized by an electrically driven telescopic structure.

[0014] As a further optimization scheme of the present invention, the telescopic foot is automatically triggered by a trigger device, and the trigger device includes a sliding rod slidably arranged in the base, the sliding rod is connected to the telescopic foot through a connecting rod, and a first spring and a second spring are respectively provided at both ends of the sliding rod, wherein the end of the first spring is connected to the telescopic rod that passes through the outside of the base, and the second spring contacts the inner wall of the base, and a second side groove is opened on the inner side of the protective wall, and a sliding part is slidably arranged in the second side groove. After the sliding part is extended, the cabin moves so that the sliding part squeezes the telescopic rod, thereby extending the telescopic foot. This scheme is automatically triggered by setting the telescopic rod. When the elevator cabin rises from the inclined track and enters the middle of the protective wall, the telescopic rod is compressed, and the first spring is first energized. Then, the telescopic foot pops out when it is higher than the flange, and the cabin weight is supported by the telescopic foot. When rising, the telescopic rod loses contact and resets. When the elevator cabin descends from the straight track and enters the middle of the protective wall, the telescopic rod is guided by the protective wall so that the telescopic rod is compressed. When it continues to descend and enter the inclined track, the sliding part actively retracts, causing the telescopic rod to lose support, thereby retracting the telescopic foot.

[0015] As a further optimization scheme of the present invention, the extension and retraction of the sliding part are triggered by a third spring and a locking rod, a first side groove with a width smaller than the second side groove is opened above the second side groove, a locking rod is hinged in the first side groove, a protruding rod is arranged upward on the locking rod to lock the sliding part, the sliding part is extended outward by the third spring, an unlocking piece is arranged on the cabin body, the unlocking piece lifts the locking rod when the lifting cabin moves obliquely upward along the conversion track, and will not contact the locking rod when the lifting cabin moves vertically upward along the conversion track.

[0016] The beneficial effects of the present invention are:

[0017] The present invention provides a conversion mechanism for converting and docking the straight track and the inclined track, and further enables a climbing device in the lifting cabin to be rotatably connected with the cabin body, so that the climbing device can dock with tracks at different angles, and a locking structure is also provided between the climbing device and the cabin body for locking after the angle conversion, so that the cabin body can maintain a straight angle for lifting and lowering, and during the track conversion process, the cabin body is supported by the transfer mechanism to prevent the cabin body from shaking, thereby improving the safety during the conversion process.

DETAILED DESCRIPTION

[0030] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0031] Example 1

[0032] like Figure 1-11As shown, a lifting device for inclined and straight segmented construction of an intercooling tower comprises a lifting cabin 4, a straight track 1 connected to an intercooling tower 7, an inclined track 2, and a conversion mechanism 3 arranged between the straight track 1 and the inclined track 2, wherein the lifting cabin 4 comprises a cabin body 41 and a climbing device 42 rotatably arranged on the cabin body 41 and corresponding to each track, and the climbing device 42 is further provided with a pair of locking grooves 44, which are used to dock with a locking driving member 45 arranged on the cabin body 41, so that the cabin body 41 can be kept vertically fixed before and after the track conversion of the climbing device 42, and the conversion mechanism 3 comprises a conversion track 33, which is used to convert and dock with the straight track 1 and the inclined track 2;

[0033] It also includes a transfer mechanism 5, which is used to support the cabin 41 when the climbing device 42 changes track.

[0034] This solution sets a conversion mechanism 3 to convert and dock the straight track 1 and the inclined track 2, and further enables the climbing device 42 in the lifting cabin 4 to be rotatably connected to the cabin body 41, so that the climbing device 42 can dock with tracks at different angles, and a locking structure is also set between the climbing device 42 and the cabin body 41 for locking after the angle conversion, so that the cabin body 41 can maintain a straight angle for lifting and lowering, and during the track conversion process, the cabin body 41 is supported by the transfer mechanism 5 to prevent the cabin body 41 from shaking, thereby improving the safety during the conversion process.

[0035] It should be noted that the reinforcement ring 71 is not a complete annular surface, but a hollow connection. The reinforcement ring 71 and the intercooler 7 are connected by connecting ribs 72. In this solution, the track and the elevator cabin 4 both pass through the reinforcement ring 71.

[0036] The straight track 1 and the inclined track 2 are fixedly connected to the steel structure of the intercooling tower 7 through a reinforcing member 6. The reinforcing member 6 extends from the tower surface of the intercooling tower 7 to support and reinforce the track. Reinforcing members 6 of different structures can also be selected according to the spacing size.

[0037] The conversion mechanism 3 includes a driving part 31 arranged on the reinforcement ring 71, and a reduction device is arranged at the output end of the driving part 31, and a connecting shaft 32 connected to the conversion track 33 is arranged at the output end of the reduction device. The connecting shaft 32 is provided with an angle sensor and a locking device. The conversion mechanism 3 needs to have the ability to undertake the elevator cabin 4, so its connecting shaft 32 needs to be equipped with a stabilizing device so that the conversion track 33 can withstand the climbing of the elevator cabin 4, and the driving part 31 drives the connecting shaft 32 to rotate through the reduction device.

[0038] The climbing device 42 is provided with a reduction drive, a driving tooth, a guide wheel and a safety locking device, wherein racks meshing with the driving teeth are provided on the straight track 1 and the inclined track 2. The climbing device 42 is a prior art, which includes one or more reduction drives, and climbs on the track through the structure of gears and tooth grooves. Different from the prior art, the climbing device 42 and the cabin 41 in this scheme can rotate, so that when the climbing device 42 corresponds to tracks of different angles, the cabin 41 can maintain a vertical orientation. In order to prevent the cabin 41 from shaking, such as Figure 4 , 5 As shown in FIG. 9 , the locking driving member 45 on the cabin body 41 is docked with the locking groove 44 on the climbing device 42 for locking. There are two locking grooves 44, which are located on an arc with the rotating shaft 43 as the center.

[0039] The climbing device 42 is rotationally connected to the cabin 41 via a rotating shaft 43. When the climbing device 42 performs angle conversion, the rotating shaft 43 and the connecting shaft 32 are located on the same axis, so that the track switching can be performed in a fixed state of the cabin 41. When the cabin 41 is supported by the transfer mechanism 5, the cabin 41 is fixed by its own weight. At this time, the turning of the climbing device 42 driven by the conversion mechanism 3 will not affect the cabin 41, nor will it cause the cabin 41 to shake.

[0040] The transfer mechanism 5 includes a protective wall 51 mounted on a reinforcement ring 71, a flange 52 is arranged on the inner side of the protective wall 51, a base 46 is arranged inside the cabin 41, and telescopic feet 411 which can be extended to both sides are arranged on the base 46, and the telescopic feet 411 are used to straddle the surface of the flange 52 to support the cabin 41. When the cabin 41 rises into the protective wall 51, the telescopic feet 411 are extended to straddle the flange 52, and the cabin 51 is supported and fixed by its own weight, so that the passengers in the cabin will not be affected during the track switching process.

[0041] Specifically, in this solution, the telescopic foot 411 is electrically driven to achieve telescoping.

[0042] Example 2

[0043] Different from Example 1, this embodiment proposes another way to trigger the telescopic foot 411, and the telescopic foot 411 is automatically triggered by a trigger device. The trigger device includes a slide rod 49 slidably set in the base 46, and the slide rod 49 is connected to the telescopic foot 411 through a connecting rod, and a first spring 48 and a second spring 410 are respectively provided at both ends of the slide rod 49, wherein the end of the first spring 48 is connected to the telescopic rod 47 that passes through the outside of the base 46, and the second spring 410 is in contact with the inner wall of the base 46, and a second side groove 54 is opened on the inner side of the protective wall 51, and a sliding part 55 is slidably set in the second side groove 54. After the sliding part 55 is extended, the cabin 41 moves so that the sliding part 55 squeezes the telescopic rod 47, thereby extending the telescopic foot 411.

[0044] The extension and retraction of the sliding part 55 are triggered by the third spring 58 and the locking rod 59. A first side groove 53 with a width smaller than the second side groove 54 is opened above the second side groove 54. A locking rod 59 is hinged in the first side groove 53. The locking rod 59 is provided with a protrusion upward to lock the sliding part 55. The sliding part 55 is extended outward by the third spring 58. An unlocking member 412 is provided on the cabin body 41. The unlocking member 412 lifts the locking rod 59 when the lifting cabin 4 moves obliquely upward along the conversion track 33, and will not contact the locking rod 59 when the lifting cabin 4 moves vertically upward along the conversion track 33.

[0045] Specifically, Figure 4-7 As shown, when the lift cabin 4 enters the conversion track 33 from the inclined track 2, the telescopic rod 47 is compressed back into the base 46. At this time, since the telescopic foot 411 is against the flange 52, the first spring 48 stores energy. When the cabin body 41 rises to the point where the telescopic foot 411 is higher than the flange 52, the telescopic foot 411 pops out and rests on the flange 52. At this time, the climbing device 42 drops slightly so that the weight of the cabin body 41 acts on the flange 52 through the telescopic foot 411. Then the locking drive member 45 releases the lock on the climbing device 42, so that the climbing device 42 can rotate with the conversion track 33. The climbing device 42 rotates from the inclined position to the vertical position (such as Figure 10-11 As shown), the locking drive member 45 is then locked to lock the climbing device 42 with the cabin body 41, and the climbing device 42 continues to rise. When the telescopic rod 47 leaves the sliding portion 55 and the protective wall 51, it is pushed out by the first spring 48, and the telescopic foot 411 is retracted into the base 46 due to the action of the second spring 410, so that the lifting cabin 4 can rise along the straight track 1;

[0046] When the lift cabin 4 descends from the straight track 1 into the conversion track 33, a slope is provided on the protective wall 51, and the telescopic rod 47 is compressed due to the guidance of the protective wall 51, and the telescopic foot 411 is directly extended, so that the width of the first side groove 53 is smaller than the telescopic rod 47. The telescopic rod 47 will not enter the first side groove 53 and affect the locking rod 59 during the downward movement. When the telescopic foot 411 is forced to rest on the flange 52, the climbing device 42 is unlocked, the conversion track 33 is rotated to align with the inclined track 2, and the climbing device 42 is locked. At this time, the climbing device 42 climbs up along the inclined track 2 in a small amplitude. This process is to prevent the telescopic rod 47 from being suddenly unlocked and causing a sense of weightlessness. It is necessary to climb the climbing device 42 in a small amplitude to bear the force (this small amplitude climbing is also required for force transfer in Example 1). In this process, if Figure 6As shown, the unlocking member 412 moves to the upper left, which lifts the locking rod 59, and the first spring 48 and the second spring 410 overcome the third spring 58, so that the sliding part 55 retracts, wherein a guide block 57 is provided on the side of the sliding part 55, and the second side groove 54 is provided with a guide groove 58 so that the sliding part 55 has a sliding guide and a limit. When the sliding part 55 retracts, the telescopic rod 47 extends outward, that is, the telescopic foot 411 retracts, and the elevator cabin 4 is able to descend. When the elevator cabin 4 descends, the sliding part 55 is pushed out and reset by the third spring 58, and the locking rod 59 also falls again to lock the sliding part 55, reaching a reset state, so as to facilitate the next squeezing of the telescopic rod 47.

[0047] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
