Description

Technical Field

[0001] The utility model relates to the technical field of hoisting devices, in particular to a segmented hoisting device based on a large-span steel truss. Background Art

[0002] Steel trusses are trussed structures made of steel and are often used as primary load-bearing components in industrial and civil building roof structures, crane beams, bridges, and hydraulic gates. Various tower structures, such as masts, television towers, and transmission line towers, often utilize spatial steel trusses composed of three, four, or more plane trusses. The most commonly used plane truss is essentially a lattice beam, bearing the loads under lateral loads. Among steel trusses, the beam-type simply supported truss is the most common.

[0003] A Chinese utility model patent with publication number CN210944602U discloses a segmented lifting device based on a large-span steel truss, which includes a horizontal stable base and a vertical support frame. The middle of the top of the horizontal stable base is fixedly connected to the bottom of the vertical support frame. The interior of the stable operating platform is penetrated by a horizontal stable hanger, and a load-bearing plate is fixedly connected to the right side of the bottom of the horizontal stable hanger.

[0004] Regarding the above-mentioned related technologies, the inventors believe that the following defects exist: the lengths of the vertical lifting ropes and the symmetrical stable lifting ropes in the above-mentioned device are fixed and cannot be adjusted. During this process, if the height of the steel ring placement ring is high, it will lead to difficulty in installing the hoisted object into the steel frame placement ring. If the height of the steel ring placement ring is low, the hoisted object will easily collide with the ground during the hoisting process, thereby reducing the practicality of the device. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a segmented lifting device based on a large-span steel truss.

[0006] The above technical purpose of the present invention is achieved through the following technical solutions: a segmented lifting device based on a large-span steel truss, comprising a base, a longitudinal support frame fixedly provided on the upper surface of the base, an operating platform rotatably provided on the upper end of the longitudinal support frame, a horizontal hanger is installed on the operating platform, a load block is fixedly provided on the bottom surface of one end of the horizontal hanger, an internal hollow operating box is fixedly provided on the bottom surface of the horizontal hanger away from the load block, connecting rods are symmetrically provided on the bottom surface of the two connecting rods, a support plate is commonly installed on the bottom surface of the support plate, fixing ropes are symmetrically provided on the bottom surface of the support plate, and fixing rings are fixed on the ends of the two fixing ropes away from the support plate.

[0007] Furthermore, a motor is fixedly provided on the inner top wall of the operation box, a threaded rod is fixedly provided on the end of the output shaft of the motor, the threaded rod passes through the operation box and extends outside the operation box, and the threaded rod is threadedly connected to the support plate.

[0008] By adopting the above technical solution, when workers need to hoist the construction product, they need to fix the construction product using a fixing ring (this utility model is mainly used to solve the lifting problem, so the structure of the fixing ring is not described in detail). Subsequently, the worker needs to start the motor, thereby rotating the motor output shaft, so that the threaded rod rotates synchronously with the motor output shaft under the action of the motor output shaft, and then the support plate moves upward under the action of the threaded rod, so that the fixing rope and the pull ring move upward under the action of the support plate, and then the construction product moves upward under the action of the fixing ring. In this process, the height of the fixing ring can be adjusted during the hoisting process, which reduces the difficulty for workers to fix the construction product and reduces the probability of collision during transportation, thereby improving the stability of the device.

[0009] Furthermore, the connecting rod includes two sleeves symmetrically arranged on the bottom surface of the operation box and two sleeve rods slidably arranged in the two sleeves respectively, and the bottom surfaces of the two sleeve rods are fixed to the upper surface of the support plate.

[0010] By adopting the above technical solution, when the support plate moves upward under the action of the threaded rod, the sleeve rod slides relative to the sleeve under the action of the support plate. In this process, the probability of the connecting rod blocking the support plate during the movement of the support plate is reduced, thereby improving the stability of the device.

[0011] Furthermore, a limiting groove is provided on the inner wall of the sleeve, a limiting block is slidably arranged in the limiting groove, and the limiting block and the sleeve rod are fixed to each other.

[0012] By adopting this technical solution, when the sleeve rod slides, the stop block slides synchronously with it under the action of the sleeve rod. During this process, when the bottom surface of the stop block abuts the inner bottom wall of the stop groove, the sleeve rod cannot slide further, thereby reducing the probability of separation between the sleeve and the sleeve rod. In addition, the probability of separation between the support plate and the threaded rod is also reduced, thereby improving the stability of the device.

[0013] Furthermore, an accommodating groove is provided on the inner bottom wall of the limiting groove, an optical fiber sensor is installed in the accommodating groove, and the optical fiber sensor is electrically connected to the motor.

[0014] By adopting the above technical solution, when the bottom surface of the limit block abuts the inner bottom wall of the limit groove, the optical fiber sensor detects the limit block. At this time, the optical fiber sensor is triggered, and the motor stops rotating, thereby reducing the probability of damage to the threaded rod and the support plate caused by continued rotation of the motor while the bottom surface of the limit block abuts the inner bottom wall of the limit groove.

[0015] Furthermore, an auxiliary frame is fixedly provided on the upper surface of the horizontal hanger, and auxiliary ropes are fixedly provided on two opposite side walls of the auxiliary frame, and the other end of the auxiliary rope is fixedly provided on the upper surface of the horizontal hanger.

[0016] By adopting the above technical solution, the auxiliary frame and the auxiliary rope improve the stability during the hoisting process, thereby reducing the probability of accidents during the hoisting process.

[0017] Furthermore, the auxiliary rope is made of stainless steel.

[0018] By adopting the above technical solution, the auxiliary rope made of stainless steel has the effects of high strength and high toughness, thereby reducing the probability of damage to the auxiliary rope and extending the service life of the device.

[0019] In summary, the present invention has the following beneficial effects:

[0020] 1. In this application, when the staff needs to hoist the construction product, the staff needs to fix the construction product through the fixing ring (this utility model is mainly used to solve the lifting problem, so the structure of the fixing ring is not introduced in detail). Afterwards, the staff needs to start the motor, and then rotate the output shaft of the motor, so that the threaded rod rotates synchronously with the motor output shaft under the action of the motor output shaft, and then the support plate moves upward under the action of the threaded rod, so that the fixing rope and the pull ring move upward under the action of the support plate, and then the construction product moves upward under the action of the fixing ring. In this process, the height of the fixing ring can be adjusted during the hoisting process, which reduces the difficulty of the staff in fixing the construction product and reduces the probability of collision during transportation, thereby improving the stability of the device;

[0021] 2. In this application, when the support plate moves upward under the action of the threaded rod, the sleeve rod slides relative to the sleeve under the action of the support plate. In this process, the probability of the connecting rod blocking the support plate during movement is reduced, thereby improving the stability of the device;

[0022] 3. In this application, when the sleeve rod slides, the stopper, under the action of the sleeve rod, slides synchronously with it. During this process, when the bottom surface of the stopper abuts the inner bottom wall of the stop slot, the sleeve rod cannot slide further, thereby reducing the probability of separation between the sleeve and the sleeve rod. In addition, the probability of separation between the support plate and the threaded rod is reduced, thereby improving the stability of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; it is obvious that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0028] like Figure 1-3As shown, the embodiment of the present application discloses a segmented lifting device based on a large-span steel truss, comprising a base 1, a longitudinal support frame 11, an operating platform 12, a horizontal hanger 13, a weight block 14, an operating box 15, a connecting rod 3, a support plate 16, a fixing rope 17, a fixing ring 18, a motor 2, a threaded rod 21, a limit block 41, and an optical fiber sensor 51. The base 1 is a rectangular plate-like structure, and the longitudinal support frame 11 is fixedly arranged on the upper surface of the base 1. The operating platform 12 is rotatably arranged on the upper surface of the longitudinal support frame 11, and the horizontal hanger 13 is installed on the operating platform 12. The weight block 14 is fixedly arranged on the bottom surface of one end of the horizontal hanger 13 for balancing the weight. The operating box 15 is a rectangular parallelepiped structure with a hollow interior, and the operating box 15 is fixedly arranged on the bottom surface of the horizontal hanger 13 away from the weight block 14. Two connecting rods 3 are provided and symmetrically arranged on the bottom surface of the operating box 15. The support plate 16 is a rectangular plate-like structure, and the support plate 16 is installed on the bottom surfaces of the two connecting rods 3. There are two fixing ropes 17 , one end of each fixing rope 17 is symmetrically arranged on the bottom surface of the support plate 16 , and there are two fixing rings 18 , which are respectively fixed on one end of each fixing rope 17 away from the support plate 16 .

[0029] Motor 2 is fixedly mounted on the inner top wall of operating box 15, with the axis of its output shaft vertical. Threaded rod 21 is fixedly mounted on the end of the output shaft of motor 2, with its axis coinciding with the axis of the output shaft of motor 2. Threaded rod 21 penetrates operating box 15 and extends outside of operating box 15, and is threadedly connected to support plate 16.

[0030] When workers need to hoist a construction product, they need to secure it with the fixing ring 18 (this utility model is mainly used to solve the lifting problem, so the structure of the fixing ring 18 is not described in detail). Subsequently, the worker needs to start the motor 2, thereby rotating the output shaft of the motor 2, so that the threaded rod 21 rotates synchronously with the output shaft of the motor 2 under the action of the output shaft of the motor 2, and then the support plate 16 moves upward under the action of the threaded rod 21, so that the fixing rope 17 and the pull ring move upward under the action of the support plate 16, and then the construction product moves upward under the action of the fixing ring 18. During this process, the height of the fixing ring 18 can be adjusted during the hoisting process, which reduces the difficulty for workers to secure the construction product and reduces the probability of collision during transportation, thereby improving the stability of the device.

[0031] The connecting rod 3 includes a sleeve 31 and a sleeve rod 32. The sleeve 31 is a round rod-shaped structure with an open lower end and a vertical axis. Two sleeves 31 are provided and symmetrically arranged on the bottom surface of the operation box 15. The sleeve rod 32 is a round rod-shaped structure with its axis coinciding with the axis of the sleeve 31. Two sleeve rods 32 are provided and slidably disposed within the two sleeves 31, and the bottom surfaces of the two sleeve rods 32 are fixed to the upper surface of the support plate 16.

[0032] When the support plate 16 moves upward under the action of the threaded rod 21, the sleeve rod 32 slides relative to the sleeve 31 under the action of the support plate 16. In this process, the probability of the connecting rod 3 blocking the support plate 16 during the movement of the support plate 16 is reduced, thereby improving the stability of the device.

[0033] A limiting groove 4 is provided on the inner wall of the sleeve 31 . The limiting block 41 is an annular structure, and its axis coincides with the axis of the sleeve rod 32 . The limiting block 41 is slidably arranged in the limiting groove 4 , and the limiting block 41 and the sleeve rod 32 are fixed to each other.

[0034] When the sleeve rod 32 slides, the stopper 41 slides synchronously with the sleeve rod 32 under the action of the sleeve rod 32. During this process, when the bottom surface of the stopper 41 abuts the inner bottom wall of the stopper groove 4, the sleeve rod 32 cannot slide further, thereby reducing the probability of separation between the sleeve 31 and the sleeve rod 32. In addition, the probability of separation between the support plate 16 and the threaded rod 21 is reduced, thereby improving the stability of the device.

[0035] An accommodating groove 5 is provided on the inner bottom wall of the limiting groove 4 . An optical fiber sensor 51 is installed in the accommodating groove 5 . The optical fiber sensor 51 is electrically connected to the motor 2 . The model of the optical fiber sensor 51 is FX-200.

[0036] When the bottom surface of the limit block 41 abuts the inner bottom wall of the limit groove 4, the optical fiber sensor 51 detects the limit block 41. At this time, the optical fiber sensor 51 is triggered, and the motor 2 stops rotating, thereby reducing the probability that the threaded rod 21 and the support plate 16 will continue to engage and be damaged due to the continuous rotation of the motor 2 when the bottom surface of the limit block 41 abuts the inner bottom wall of the limit groove 4.

[0037] To reduce the probability of accidents during the hoisting process, an auxiliary frame 6 is fixedly mounted on the upper surface of the horizontal hanger 13. Auxiliary ropes 61 are fixedly mounted on two opposing side walls of the auxiliary frame 6, and the other ends of the auxiliary ropes 61 are fixedly mounted on the upper surface of the horizontal hanger 13. The auxiliary frame 6 and auxiliary ropes 61 improve stability during the hoisting process, thereby reducing the probability of accidents during the hoisting process.

[0038] In order to extend the service life of the device, the auxiliary rope 61 is made of stainless steel. The auxiliary rope 61 made of stainless steel has high strength and high toughness, thereby reducing the probability of damage to the auxiliary rope 61, thereby extending the service life of the device.

[0039] The principle of use of a segmented lifting device based on a large-span steel truss in this embodiment is as follows: when a worker needs to lift a construction product, the worker needs to fix the construction product through a fixing ring 18 (this utility model is mainly used to solve the lifting problem, so the structure of the fixing ring 18 is not described in detail). Subsequently, the worker needs to start the motor 2, thereby rotating the output shaft of the motor 2, so that the threaded rod 21 rotates synchronously with the output shaft of the motor 2 under the action of the output shaft of the motor 2, and then the support plate 16 moves upward under the action of the threaded rod 21, so that the fixing rope 17 and the pull ring move upward under the action of the support plate 16, and then the construction product moves upward under the action of the fixing ring 18. In this process, the height of the fixing ring 18 can be adjusted during the lifting process, which reduces the difficulty for the worker to fix the construction product and reduces the probability of collision during transportation, thereby improving the stability of the device.

[0040] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
