Description

Technical Field

[0001] This application belongs to the technical field of engineering construction equipment, and specifically relates to a construction hoist and its cage connection bracket. Background Technology

[0002] Construction hoists are one of the important special equipment for transporting people and materials to higher places on construction sites. Construction hoists include guide rails, drive units, and cages. The cage is driven by the drive unit to move up and down along the guide rails. Since the cage car is a hollow structure for carrying people and goods, directly connecting the car to the drive unit may lead to a safety accident due to insufficient strength at the connection point. Utility Model Content

[0003] The purpose of this application is to provide a construction hoist and its cage connection bracket, which aims to strengthen the connection strength between the various parts of the cage and the drive part.

[0004] To achieve the above objectives, this application provides a cage connection bracket for a construction hoist, comprising a fixedly connected vertical bracket and a longitudinal bracket. The top of the vertical bracket is provided with a cage ear plate, and a vertical positioning component is provided on the vertical bracket. The vertical positioning component and the longitudinal bracket are located on the same side of the vertical bracket. A longitudinal positioning component is provided on the longitudinal bracket, and the longitudinal positioning component and the vertical bracket are located on the same side of the longitudinal bracket. Both the vertical positioning component and the longitudinal positioning component are used to connect with the cage car.

[0005] In some embodiments, the longitudinal support is arranged at the bottom of the vertical support and on one side of the vertical support along the longitudinal direction, and the longitudinal support is provided with a support guide assembly on the other side of the longitudinal direction. The support guide assembly is used to movably connect the vertical support and the guide rail device.

[0006] In some embodiments, the bracket guide assembly includes a bracket transverse guide roller assembly and a bracket longitudinal guide roller assembly that cooperate with the rollers of the guide rail assembly, wherein the axle of the bracket transverse guide roller assembly extends longitudinally and the axle of the bracket longitudinal guide roller assembly extends transversely.

[0007] In some embodiments, the bracket transverse guide roller assemblies are arranged in pairs along the transverse direction, and the two pairs of bracket transverse guide roller assemblies are spaced apart along the transverse direction and form a transverse holding portion for clamping the guide rail frame device.

[0008] In some embodiments, the bracket longitudinal guide roller assemblies are arranged in pairs along the longitudinal direction, and the two pairs of bracket longitudinal guide roller assemblies are spaced apart along the longitudinal direction and form a longitudinal holding portion for clamping the guide rail frame device.

[0009] In some embodiments, the number of the bracket transverse guide roller assemblies is multiple and the multiple bracket transverse guide roller assemblies are arranged at vertical intervals.

[0010] In some embodiments, the number of the bracket longitudinal guide roller assemblies is multiple and the multiple bracket longitudinal guide roller assemblies are arranged at vertical intervals.

[0011] In some embodiments, the vertical support is provided with a safety device main board for installing a fall arrestor. The vertical support is a frame structure, and the safety device main board is embedded in the vertical support. The inner peripheral wall of the vertical support is provided with a cage bracket mounting plate. Both the safety device main board and the cage bracket mounting plate are provided with holes for fasteners of the cage bracket to pass through, and the holes on the safety device main board are different in size from the holes on the cage bracket mounting plate.

[0012] In some embodiments, the cage support fastener includes a cage support fastening screw, and the cage connecting bracket further includes a cage support locking nut that is threadedly engaged with the cage support fastening screw. A first cage support rubber pad is provided between the safety device main board and the cage support mounting plate, and a second cage support rubber pad is provided between the head of the cage support fastening screw and the safety device main board. Both the first cage support rubber pad and the second cage support rubber pad are sleeved on the cage support fastening screw.

[0013] In some embodiments, a cage support pressure plate is provided between the head of the cage support fastening screw and the main board of the safety device. The size of the cage support pressure plate is larger than the head of the cage support fastening screw. The cage support pressure plate is sleeved on the cage support fastening screw, and the second cage support rubber pad is located between the cage support pressure plate and the main board of the safety device.

[0014] Another aspect of this application provides a construction hoist, including the cage connection bracket of the construction hoist as described above.

[0015] The construction hoist and its cage connection bracket provided in this application have the following beneficial effects through the above technical solution: This application provides a cage connecting bracket for connecting a cage car to a lifting drive device of a construction hoist. Specifically, the cage ear plate on the vertical bracket is used to connect with the lifting drive device, and the longitudinal bracket is used to support the cage car. The vertical bracket and the longitudinal bracket are fixedly connected, thereby realizing the connection between the lifting drive device and the cage car. It can be seen that the connection between the cage car and the lifting drive device as the drive part changes from a direct connection to an indirect connection. Moreover, the structural strength of the cage connecting bracket is greater than the structural strength of the cage car, which is beneficial to strengthening the connection strength between the cage part and the drive part.

Detailed Implementation

[0019] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0020] The terminology of the construction hoist and its cage connection bracket according to this application is described below with reference to the accompanying drawings.

[0021] like Figures 1 to 3 As shown in the figure, a specific embodiment of this application provides a cage connection bracket 53 for a construction hoist, including a vertical bracket 531 and a longitudinal bracket 532 fixedly connected. The top of the vertical bracket 531 is provided with a cage ear plate 539. The vertical bracket 531 is provided with a vertical positioning member, which is located on the same side of the vertical bracket 531 as the longitudinal bracket 532. The longitudinal bracket 532 is provided with a longitudinal positioning member, which is located on the same side of the longitudinal bracket 532 as the vertical bracket 531. Both the vertical positioning member and the longitudinal positioning member are used to connect with the cage car 52.

[0022] The construction hoist includes a lifting drive unit 400 as the driving component, a guide rail frame assembly 200 as the guiding component, and a cage assembly. The lifting drive unit 400, guide rail frame assembly 200, and cage assembly are manufactured separately. After production, all parts need to be assembled to form the construction hoist. Specifically, the lifting drive unit 400 is connected to the cage assembly and interacts with the guide rail frame assembly 200 to drive the cage assembly to rise and fall. The connection strength between the cage assembly and the lifting drive unit 400 is crucial to the safety of the construction hoist. In this application, the cage assembly is installed on a cage connecting bracket 53 to form a cage system 500. The hoisting car 52 of the device is connected to the vertical support 531 of the hoisting car connecting bracket 53 via a vertical positioning component, and to the longitudinal support 532 of the hoisting car connecting bracket 53 via a longitudinal positioning component, so as to ensure the stability of the connection between the hoisting car 52 and the hoisting car connecting bracket 53. On this basis, since the hoisting car 52 is a hollow structure and does not have good structural strength, the hoisting car 52 of the hoisting device is connected to the lifting drive device 400 via the hoisting ear plate 539 on the hoisting car connecting bracket 53, which replaces the connection between the hoisting car 52 and the lifting drive device 400, so as to strengthen the connection strength between the hoisting device and the lifting drive device 400, thereby improving the load-bearing capacity and safety of the construction hoist.

[0023] Furthermore, the cage car 52 can be equipped with a cage positioning structure that is aligned with the vertical positioning component and the longitudinal positioning component. This structure can also play an auxiliary positioning role in the installation of the cage car 52 onto the cage connecting bracket 53, thereby enabling the rapid installation of the cage car 52.

[0024] Optionally, the vertical positioning component includes a vertical positioning post 533 of the cage extending longitudinally, and a vertical positioning hole of the cage is correspondingly provided on the cage car 52. The vertical positioning of the cage car 52 is achieved by the insertion and cooperation of the vertical positioning post 533 of the cage with the vertical positioning hole of the cage.

[0025] Optionally, the longitudinal positioning component includes a longitudinal positioning column 534 of the cage extending vertically, and a corresponding longitudinal positioning hole is provided on the cage car 52. The longitudinal positioning of the cage car 52 is achieved by the insertion and cooperation between the longitudinal positioning column 534 of the cage and the longitudinal positioning hole of the cage.

[0026] Those skilled in the art will understand that the vertical positioning element and longitudinal positioning element of this application are not limited to the above-mentioned columnar structure, but may also be other structural forms such as groove structure, and other structural forms should also fall within the protection scope of this application.

[0027] Furthermore, the vertical support 531 extends vertically, and the longitudinal support 532 extends longitudinally. The longitudinal support 532 is arranged at the bottom of the vertical support 531 and located on one side of the vertical support 531 along the longitudinal direction. A support guide assembly is provided on the other side of the longitudinal support 532. The hoisting cage 52 is installed above the longitudinal support 532. The support guide assembly is used to movably connect the vertical support 531 and the guide rail device 200. By increasing the movable cooperation between the support guide assembly and the guide rail device 200, the connection stability between the hoisting cage system 500 and the guide rail device 200 is increased, thereby further improving the stability and safety of the hoisting cage 52 during the lifting process, and thus improving the load-bearing capacity and safety of the construction hoist.

[0028] like Figure 4 As shown in the specific embodiment of this application, the guide rail frame device 200 includes a guide rail frame body, which includes multiple main chord rods 22 extending vertically and horizontal rods 23 connecting adjacent main chord rods 22. The main chord rods 22 can serve as guide rails. There are two main chord rods 22, and the two main chord rods 22 are arranged laterally at intervals. The horizontal rods 23 extend laterally to connect the two main chord rods 22. The vertical support 531 is mounted on the main chord rods 22 through the support guide assembly and can move along the main chord rods 22.

[0029] In some embodiments, the bracket guide assembly includes a bracket transverse guide roller assembly and a bracket longitudinal guide roller assembly that roll in cooperation with the main chord 22, the axle of the bracket transverse guide roller assembly extending longitudinally and the axle of the bracket longitudinal guide roller assembly extending transversely.

[0030] Specifically, the bracket transverse guide roller assemblies are arranged in pairs along the transverse direction. The two pairs of bracket transverse guide roller assemblies are arranged laterally at intervals and form transverse holding portions for clamping the main chord 22. The two pairs of bracket transverse guide roller assemblies are respectively in rolling engagement with the two main chords 22, and both main chords 22 are located within the transverse holding portions. The bracket longitudinal guide roller assemblies are arranged in pairs along the longitudinal direction. The two pairs of bracket longitudinal guide roller assemblies are arranged longitudinally at intervals and form longitudinal holding portions for clamping the main chord 22. The two pairs of bracket longitudinal guide roller assemblies are in rolling engagement with the same main chord 22, and the main chord 22 is located within the longitudinal holding portions. The cage connecting bracket 53 and the guide rail frame device 200 are limited in the lateral direction by the lateral holding part and the main chord 22, and the cage connecting bracket 53 and the guide rail frame device 200 are limited in the longitudinal direction by the longitudinal holding part and the main chord 22, so as to ensure the stability of the cage connecting bracket 53 during the lifting process, thereby ensuring the stability of the cage car 52 installed on the cage connecting bracket 53 during the lifting process.

[0031] like Figure 5 and Figure 6 As shown, in some embodiments, the support transverse guide roller assembly includes a support transverse guide roller 511 and an eccentric shaft 44. A roller bearing 443 is sleeved on the eccentric shaft 44. The support transverse guide roller 511 is connected to the roller bearing 443. The eccentric shaft 44 extends longitudinally and connects the support transverse guide roller 511 to the cage connecting bracket 53. The lateral position of the support transverse guide roller 511 is adjusted by rotating the eccentric shaft 44, so that the roller surface of the support transverse guide roller 511 abuts against the outer wall surface of the main chord 22. This ensures that the support transverse guide roller 511 and the outer wall surface of the main chord 22 are not easily separated during operation, thereby ensuring the rolling cooperation between the support transverse guide roller 511 and the main chord 22. This, in turn, ensures the stability of the cage connecting bracket 53 during the lifting process and overcomes the influence of manufacturing errors on the connection between the cage connecting bracket 53 and the guide rail device 200.

[0032] Specifically, the eccentric shaft 44 includes a reference journal 441 and an eccentric journal 442 connected axially. An eccentricity is provided between the axis of the reference journal 441 and the axis of the eccentric journal 442. An annular groove is formed on the outer peripheral wall of the eccentric journal 442. A roller bearing 443 is sleeved on the eccentric journal 442 and located within the annular groove, with its outer ring flush with the outer peripheral wall of the eccentric journal 442. The reference journal 441 passes through the vertical support 531 and is rotatably connected to the vertical support 531 via a bearing. The outer ring of the roller bearing 443 is nested with the transverse guide roller 511 of the support. Rotating the eccentric shaft 44 allows the transverse guide roller 511 to move in a plane perpendicular to the axis of the eccentric shaft 44, thereby adjusting the position of the transverse guide roller 511 and thus adjusting the distance between the transverse guide roller 511 and the main chord 22.

[0033] Furthermore, the bracket transverse guide roller assembly also includes an eccentric wheel shaft fastening nut 444 that is fastened to the reference journal 441. The eccentric wheel shaft fastening nut 444 and the bracket transverse guide roller 511 are located on both sides of the vertical bracket 531 along the longitudinal direction. After the bracket transverse guide roller 511 is adjusted to its position by rotating the eccentric wheel shaft 44, the reference journal 441 and the vertical bracket 531 are locked by screwing the eccentric wheel shaft fastening nut 444 until it contacts the vertical bracket 531, so as to restrict the relative rotation between the reference journal 441 and the vertical bracket 531, thereby completing the position adjustment of the bracket transverse guide roller 511.

[0034] like Figure 7 and Figure 8As shown, in some embodiments, the longitudinal guide roller assembly includes a longitudinal guide roller 512 and an eccentric shaft 44. A roller bearing 443 is sleeved on the eccentric shaft 44. The longitudinal guide roller 512 is connected to the roller bearing 443. The eccentric shaft 44 extends laterally and connects the longitudinal guide roller 512 to the cage connecting bracket 53. The longitudinal position of the longitudinal guide roller 512 is adjusted by rotating the eccentric shaft 44, so that the roller surface of the longitudinal guide roller 512 abuts against the outer wall surface of the main chord 22. This ensures that the longitudinal guide roller 512 and the outer wall surface of the main chord 22 are not easily separated during operation, thereby ensuring the rolling fit between the longitudinal guide roller 512 and the main chord 22. This, in turn, ensures the stability of the cage connecting bracket 53 during lifting and lowering, while overcoming the influence of manufacturing errors on the connection between the cage connecting bracket 53 and the guide rail device 200.

[0035] Specifically, the eccentric shaft 44 includes a reference journal 441 and an eccentric journal 442 connected axially. An eccentricity is provided between the axis of the reference journal 441 and the axis of the eccentric journal 442. An annular groove is formed on the outer peripheral wall of the eccentric journal 442. A roller bearing 443 is sleeved on the eccentric journal 442 and located within the annular groove, with its outer ring flush with the outer peripheral wall of the eccentric journal 442. The reference journal 441 passes through the vertical support 531 and is rotatably connected to the vertical support 531 via a bearing. The outer ring of the roller bearing 443 is nested with the longitudinal guide roller 512 of the support. Rotating the eccentric shaft 44 allows the longitudinal guide roller 512 of the support to move in a plane perpendicular to the axis of the eccentric shaft 44, thereby adjusting the position of the longitudinal guide roller 512 and thus adjusting the distance between the longitudinal guide roller 512 and the main chord 22.

[0036] Furthermore, the longitudinal guide roller assembly of the bracket also includes an eccentric wheel shaft fastening nut 444 that is fastened to the reference journal 441. The eccentric wheel shaft fastening nut 444 and the longitudinal guide roller 512 of the bracket are located on both sides of the vertical bracket 531 along the lateral direction. After the longitudinal guide roller 512 of the bracket is adjusted to the position by rotating the eccentric wheel shaft 44, the reference journal 441 and the vertical bracket 531 are locked by screwing the eccentric wheel shaft fastening nut 444 until it contacts the vertical bracket 531, so as to restrict the relative rotation between the reference journal 441 and the vertical bracket 531, thereby completing the position adjustment of the longitudinal guide roller 512 of the bracket.

[0037] It should be noted that the principle of adjusting the rollers mounted on the eccentric wheel shaft 44 by rotating the eccentric wheel shaft 44 is well known to those skilled in the art and will not be elaborated here, but it has not been applied in the assembly of the various components of the construction hoist.

[0038] Furthermore, the roller surface of the transverse guide roller 511 of the bracket is concave, and the concave roller surface is used to limit the engagement with the main chord 22 so that the transverse guide roller 511 of the bracket does not separate from the main chord 22 in the longitudinal direction; the roller surface of the longitudinal guide roller 512 of the bracket is concave, and the concave roller surface is used to limit the engagement with the main chord 22 so that the longitudinal guide roller 512 of the bracket does not separate from the main chord 22 in the transverse direction.

[0039] In some embodiments, the number of bracket transverse guide roller assemblies is multiple and the multiple bracket transverse guide roller assemblies are arranged at vertical intervals to increase the number of connection points between the cage connecting bracket 53 and the guide rail, thereby further improving the connection stability between the cage device and the guide rail frame device 200.

[0040] In some embodiments, the number of longitudinal guide roller assemblies of the support is multiple and the multiple longitudinal guide roller assemblies of the support are arranged at vertical intervals to increase the number of connection points between the cage connecting support 53 and the guide rail, thereby further improving the connection stability between the cage device and the guide rail frame device 200.

[0041] like Figure 1 and Figure 3 As shown in the specific embodiment of this application, the guide rail frame device 200 further includes a drive rail installed on the guide rail frame body, and a fall arrestor 57 is installed on the cage connecting bracket, with the fall arrestor 57 in contact with the drive rail.

[0042] In some implementations, the safety device main board 535 is adjustablely mounted on the vertical bracket 531. Since the fall arrestor 57 needs to contact and cooperate with the drive rail, the position of the fall arrestor 57 can be adjusted by setting the adjustable position of the safety device main board 535, so as to realize the position adjustment of the fall arrestor 57. Even if there are manufacturing errors between the fall arrestor 57 and the drive rail that prevent them from being assembled smoothly, the impact of manufacturing errors on assembly can be eliminated by moving the safety device main board 535.

[0043] Furthermore, the drive rail includes a lifting drive rack 21, which is mounted on the horizontal bar 23 by bolting or welding. The lifting drive device 400 includes a lifting drive gear 41 that meshes with the lifting drive rack 21. The lifting drive gear 41 interacts with the lifting drive rack 21 to achieve the lifting and lowering of the cage system 500. The fall arrestor 57 moves and engages with the lifting drive rack 21 during the lifting and lowering process of the cage system 500. If the lifting drive device 400 malfunctions or other faults cause the cage system 500 to tend to fall, the fall arrestor 57 will be activated. At this time, the fall arrestor 57 can lock onto the lifting drive rack 21 to prevent the cage system 500 from falling and causing a safety accident. In order to ensure that the fall arrestor 57 can function, the fall arrestor 57 and the lifting drive rack 21 need to be precisely assembled. The position of the safety device main board 535 can be adjusted by setting an adjustable position, so as to realize the position adjustment of the safety device main board 535. Even if there are manufacturing errors between the safety device main board 535 and the lifting drive rack 21, the impact of manufacturing errors on the assembly of the two can be eliminated by the safety device main board 535.

[0044] It should be noted that the structure and principle of the fall arrestor 57 are well known to those skilled in the art and are not part of the core inventive point of this application, so they will not be described in detail here.

[0045] like Figure 9 and Figure 10 As shown, in some embodiments, the vertical support 531 is a frame structure forming multiple rectangular cage support frames. The safety device main board 535 is embedded in one of the rectangular cage support frames. Each of the four corners of this rectangular cage support frame is provided with a cage support mounting plate 536. Both the safety device main board 535 and the cage support mounting plate 536 have holes for the cage support fasteners to pass through. The holes on the safety device main board 535 and the holes on the cage support mounting plate 536 are different in size. In other words, as long as the smaller hole is within the range of the larger hole while moving the safety device main board 535, the cage support fasteners can pass through the safety device main board 535 and the cage support mounting plate 536. After the position adjustment of the safety device main board 535 is completed, the position of the safety device main board 535 is fixed by the cage support locking member used in conjunction with the cage support fasteners.

[0046] In some embodiments, a first cage bracket rubber pad 55 is provided between the safety device main board 535 and the cage bracket mounting plate 536 to reduce the vibration between the safety device main board 535 and the cage bracket mounting plate 536 during operation, thereby achieving a shock absorption effect. This not only improves the stability of the cage system 500 during lifting, but also reduces wear between components.

[0047] In some embodiments, the cage support fastener includes a cage support fastening screw 56, and the cage connecting bracket 53 further includes a cage support locking nut that is threadedly engaged with the cage support fastening screw 56. The cage support fastening screw 56 passes longitudinally through the safety device main board 535 and the cage support mounting plate 536. The head of the cage support fastening screw 56 is located on the side of the safety device main board 535 that is longitudinally away from the cage support mounting plate 536. The cage support locking nut is located on the side of the cage support mounting plate 536 that is longitudinally away from the safety device main board 535. A first cage support rubber pad 55 is sleeved on the cage support fastening screw 56 and located between the safety device main board 535 and the cage support mounting plate 536.

[0048] Furthermore, a second cage bracket rubber pad 58 is provided between the head of the cage bracket fastening screw 56 and the safety device main board 535 to reduce the vibration between the safety device main board 535 and the head of the cage bracket fastening screw 56 during operation, thereby achieving a shock absorption effect. This not only improves the stability of the cage system 500 during lifting, but also reduces wear between components.

[0049] In some embodiments, a cage support pressure plate 59 is provided between the head of the cage support fastening screw 56 and the safety device main board 535. The size of the cage support pressure plate 59 is larger than the head of the cage support fastening screw 56. The cage support pressure plate 59 is sleeved on the cage support fastening screw 56. The cage support pressure plate 59 and the cage support mounting plate 536 clamp and fix the safety device main board 535. A second cage support rubber pad 58 is provided between the cage support pressure plate 59 and the safety device main board 535 to reduce the vibration between the safety device main board 535 and the cage support pressure plate 59 during operation, thereby achieving a shock absorption effect. This not only improves the stability of the cage system 500 during the lifting process, but also reduces wear between components.

[0050] In some embodiments, the safety device main board 535 is embedded in the vertical bracket 531, and a third cage bracket rubber pad 510 is provided between the safety device main board 535 and the vertical bracket 531 to reduce the vibration between the safety device main board 535 and the vertical bracket 531 during operation, thereby achieving a shock absorption effect. This not only improves the stability of the cage system 500 during lifting, but also reduces wear between components.

[0051] like Figure 9 and Figure 10As shown, in some embodiments, the vertical support 531 and the safety device main board 535 are adjustablely connected by a cage support adjustment assembly 54. The cage support adjustment assembly 54 includes a first cage support adjustment ear plate 541, a second cage support adjustment ear plate 542, a cage support adjustment bolt 543, a first cage support adjustment nut 544, a second cage support adjustment nut 545, and a third cage support adjustment nut 546. The first cage support adjustment ear plate 541 and the second cage support adjustment ear plate 542 are arranged laterally at intervals. The first cage support adjustment ear plate 541 is mounted on the safety device main board 535, and the second cage support adjustment ear plate 542 is mounted on the vertical support 531. Bolt 543 passes transversely through the first cage support adjusting ear plate 541 and the second cage support adjusting ear plate 542; the first cage support adjusting nut 544, the second cage support adjusting nut 545 and the third cage support adjusting nut 546 are threaded onto the cage support adjusting bolt 543. The head portion of the first cage support adjusting nut 544 and the head portion of the cage support adjusting bolt 543 are located on both sides of the first cage support adjusting ear plate 541. The second cage support adjusting nut 545 and the third cage support adjusting nut 546 are respectively located on both sides of the second cage support adjusting ear plate 542. The second cage support adjusting nut 545 is located between the second cage support adjusting ear plate 542 and the first cage support adjusting ear plate 541.

[0052] Specifically, during adjustment, the cage support adjusting nut needs to be loosened, and then the safety device main board 535 is moved laterally. At this time, the first cage support adjusting ear plate 541 will move along the cage support adjusting bolt 543 as the safety device main board 535 moves laterally. After adjustment, the cage support adjusting nut is tightened again. The entire adjustment process is extremely simple, and the position of the safety device main board 535 is fixed by the lateral limiting cooperation between the paired cage support adjusting nuts and the cage support adjusting ear plates, making the adjustment process more reliable.

[0053] Furthermore, a cage bracket disc spring 547 is provided between the second cage bracket adjusting ear plate 542 and the third cage bracket adjusting nut 546. The cage bracket disc spring 547 is used to prevent the third cage bracket adjusting nut 546 from loosening.

[0054] Thus, the specific embodiments of this application provide two methods to overcome manufacturing errors and smoothly complete the assembly of the cage connecting bracket 53 and the guide rail device 200. The first method is to adjust the relative position of the safety device main board 535 and the vertical bracket 531 by adjusting the cage bracket adjusting component 54. The second method is to adjust the position of the bracket's transverse guide roller 511 and longitudinal guide roller 512 by adjusting the eccentric wheel shaft 44. In fact, the first method can achieve a larger positional movement, while the second method can achieve a smaller positional movement. In other words, the first method can solve the assembly problem caused by a large manufacturing error, while the second method can solve the assembly problem caused by a small manufacturing error. Alternatively, the first method can be used for coarse adjustment, and the second method can be used for fine adjustment to solve the assembly problem caused by manufacturing errors, thereby overcoming the influence of manufacturing errors on the connection between the cage connecting bracket 53 and the guide rail device 200.

[0055] In some embodiments, the cage connecting bracket 53 is provided with a safety hook pin 513, which engages with the guide rail device 200 in a longitudinal limiting manner to provide redundant protection for the connection between the cage connecting bracket 53 and the guide rail device 200, thereby further improving safety.

[0056] like Figure 2 and Figure 3 As shown, a specific embodiment of this application also provides a hoisting system 500, including the hoisting connecting bracket 53 and the hoisting car 52 described above. Since the hoisting system 500 adopts all embodiments of the hoisting connecting bracket 53, the hoisting system 500 has all the beneficial effects brought by all embodiments of the hoisting connecting bracket 53.

[0057] like Figure 11 As shown, a specific embodiment of this application also provides a construction hoist, including the aforementioned cage system 500. Since the construction hoist employs all embodiments of the cage system 500, it possesses all the beneficial effects of all embodiments of the cage system 500.
