Description

Technical Field

[0001] This utility model relates to the field of tower crane attachment technology, specifically an adjustable attachment support tool for tower cranes. Background Technology

[0002] A tower crane, also known as a tower hoist, is a type of fully rotating crane with a vertical tower. During the fixing process, the tower crane needs to be connected to the wall using attachment fixtures.

[0003] Chinese Patent No. 202221612981.1 discloses an adjustable attachment support fixture for tower cranes, including a first mounting frame, a second mounting frame, a first adjustment component, and a second adjustment component. A fixed plate is fixedly connected to one outer wall of the first mounting frame, and a movable plate is provided on one outer wall of the first mounting frame. A fixed plate is fixedly connected to one outer wall of the second mounting frame, and a movable plate is provided on one outer wall of the second mounting frame. Rectangular openings are provided on the top and bottom outer walls of both the first and second mounting frames.

[0004] This invention has a small adjustable range and is very cumbersome to adjust, which affects the assembly and use of the equipment. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable attachment support fixture for tower cranes to solve the problems mentioned in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable attachment support fixture for tower cranes, comprising a support device; the support device consists of an adjustable support rod, a mounting frame, a first side plate, a second side plate, and an adjustment plate; a fixing member is installed on the upper end of the first side plate, the second side plate, and the adjustment plate; the fixing member fixes the first side plate, the second side plate, and the adjustment plate to the outside of the tower crane; both ends of the adjustment plate are slidably mounted on one end of the first side plate and the second side plate via a sliding mechanism; one end of the first side plate and the second side plate is mounted on the upper side of the adjustment mechanism; the adjustment mechanism is installed inside the mounting frame; both ends of the adjustable support rod are equipped with bearing seats; the bearing seat at one end of the adjustable support rod is mounted on the upper side of the mounting plate; the mounting plate is mounted on the upper side of the wall; the bearing seat at the other end of the adjustable support rod is mounted on both ends of the mounting frame; and the two adjustable support rods on one side of the mounting frame form a triangle with the wall.

[0007] Preferably, the adjusting mechanism consists of a bidirectional lead screw, a lead screw nut, and a slider. The bidirectional lead screw is rotatably installed in the middle of the mounting frame. One end of the bidirectional lead screw passes through the outside of the mounting frame and has a first through hole. The lead screw nut is rotatably installed at both ends of the bidirectional lead screw. The slider is installed outside the lead screw nut and is slidably installed inside the mounting frame.

[0008] Preferably, the adjustable support rod consists of a threaded rod and a bidirectional threaded cylinder, with the two threaded rods respectively mounted at both ends of the bidirectional threaded cylinder via threaded rotation.

[0009] Preferably, fixing bolts are rotatably installed on both sides of the bidirectional threaded cylinder, and the fixing bolts are rotatably installed inside the bidirectional threaded cylinder and in contact with the threaded rod.

[0010] Preferably, a first through hole is provided at the middle position of the bidirectional threaded cylinder, and the first through hole penetrates the bidirectional threaded cylinder.

[0011] Preferably, the sliding mechanism consists of a sliding plate and a sliding groove. The sliding groove is disposed at one end of the first side plate and the second side plate. The sliding plate is installed on both sides of the adjusting plate and is slidably installed inside the sliding groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By adjusting the spacing between the first and second side plates through the adjustment mechanism, and combined with the length adjustment of the adjustable support rod, three-dimensional fine adjustment of the support position can be achieved, ensuring that the tooling fits tightly with the tower crane and the wall, avoiding support loosening caused by uneven force. It is suitable for installation needs under different working conditions, and the triangular support structure can effectively distribute the load, reduce the risk of single-point force, and ensure the stability and safety of the tower crane during operation.

[0014] 2. The adjustment mechanism uses a bidirectional lead screw as its core driving component. During operation, an external tool is inserted into the first through hole at one end of the bidirectional lead screw and rotated, causing the bidirectional lead screw to rotate inside the mounting frame. Since the threads at both ends of the bidirectional lead screw turn in opposite directions, its rotational motion can be converted into relative or opposite linear motion of the lead screw nuts at both ends. This, in turn, drives the outer slider to slide synchronously inside the mounting frame. The slider is connected to the first side plate and the second side plate. By sliding the slider, the distance between the first side plate and the second side plate can be precisely adjusted, achieving adaptation to tower cranes of different sizes. The advantages of this structure are that the bidirectional lead screw transmission has high precision, enabling fine-tuning control of the distance and ensuring a tight fit between the side plate and the tower crane; the cooperation between the lead screw nut and the slider is smooth and without jamming, and it has a strong load-bearing capacity, maintaining a stable support state after adjustment and avoiding position deviation. At the same time, the structure is simple and compact, easy to operate, and can be adjusted without complicated tools, improving installation efficiency.

[0015] 3. The core of the adjustable support rod's operation is the use of threaded transmission to achieve length adjustment, meeting different installation spacing requirements. Two threaded rods are screwed into both ends of a double-threaded cylinder. Since the threads at both ends of the double-threaded cylinder turn in opposite directions, when the double-threaded cylinder is rotated, the two threaded rods will simultaneously retract into the cylinder or extend outward, thereby quickly adjusting the total length of the entire adjustable support rod. The advantages of this design are: a wide adjustment range, adapting to different distance differences between walls and tower cranes; the threaded transmission has a self-locking function, maintaining stability after adjustment to the required length without additional fixing, preventing length changes during use; and high structural strength, effectively transmitting support force. Combined with the overall triangular support structure, it further enhances the load-bearing capacity and stability of the tooling, while being easy to assemble and disassemble, facilitating transportation and reuse.

[0016] 4. The sliding mechanism provides a smooth sliding guide for the adjusting plate. When the adjusting mechanism drives the first and second side plates to move, the adjusting plate slides synchronously in the slide groove via the sliding plate, ensuring that the adjusting plate always remains in contact with the tower crane surface. The small gap between the sliding plate and the slide groove prevents offset during sliding, ensuring adjustment accuracy. The slide groove limits the sliding plate, preventing the adjusting plate from falling off or becoming misaligned, thus improving structural stability. Furthermore, the smooth sliding contact surface has low friction, ensuring a smooth and uninterrupted adjustment process, reducing adjustment resistance. At the same time, the good wear resistance of the sliding plate and the slide groove means that they are not easily worn over long-term use, ensuring the service life of the sliding mechanism and the long-term reliability of the adjustment function.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 In this embodiment of the utility model, an adjustable attachment support fixture for a tower crane includes a support device 1. The support device 1 is characterized by comprising an adjustable support rod 4, a mounting frame 5, a first side plate 6, a second side plate 14, and an adjusting plate 16. Fixing members 15 are installed on the upper ends of the first side plate 6, the second side plate 14, and the adjusting plate 16, fixing them to the outside of the tower crane. The two ends of the adjusting plate 16 are slidably mounted on one end of the first side plate 6 and the second side plate 14 via a sliding mechanism 7. One end of the first side plate 6 and the second side plate 14 is mounted on the upper side of an adjusting mechanism 18, which is installed inside the mounting frame 5. Shaft seats 3 are installed on both ends of the adjustable support rod 4. The shaft seat 3 at one end of the adjustable support rod 4 is mounted on the upper side of the mounting plate 2, which is mounted on the upper side of the wall. The shaft seat 3 at the other end of the adjustable support rod 4 is mounted on both ends of the mounting frame 5. A triangle is formed between the two adjustable support rods 4 on one side of the mounting frame 5 and the wall.

[0025] The adjustment mechanism 18 consists of a bidirectional lead screw 21, a lead screw nut 20, and a slider 19. The bidirectional lead screw 21 is rotatably installed in the middle of the mounting frame 5. One end of the bidirectional lead screw 21 passes through the outside of the mounting frame 5 and is provided with a first through hole 13. The lead screw nut 20 is rotatably installed at both ends of the bidirectional lead screw 21. The slider 19 is installed outside the lead screw nut 20 and is slidably installed inside the mounting frame 5. The adjustment mechanism 18 uses a bidirectional lead screw 21 as its core driving component. During operation, an external tool is inserted into the first through hole 13 at one end of the bidirectional lead screw 21 and rotated, causing the bidirectional lead screw 21 to rotate inside the mounting frame 5. Since the threads at both ends of the bidirectional lead screw 21 turn in opposite directions, its rotational motion can be converted into relative or opposite linear motion of the lead screw nuts 20 at both ends, thereby driving the outer slider 19 to slide synchronously inside the mounting frame 5. The slider 19 is connected to the first side plate 6 and the second side plate 14. By sliding the slider 19, the distance between the first side plate 6 and the second side plate 14 can be precisely adjusted, achieving adaptation to tower cranes of different sizes. The advantages of this structure are that the bidirectional lead screw 21 has high transmission accuracy, enabling fine-tuning control of the distance and ensuring a tight fit between the side plate and the tower crane; the screw nut 20 and the slider 19 cooperate smoothly without jamming, and have strong load-bearing capacity, maintaining a stable support state after adjustment and avoiding position deviation. At the same time, the structure is simple and compact, easy to operate, and can be adjusted without complicated tools, improving installation efficiency.

[0026] The adjustable support rod 4 consists of threaded rods 10 and a double-threaded cylinder 12. The two threaded rods 10 are respectively installed at both ends of the double-threaded cylinder 12 via threaded rotation. The core of the adjustable support rod 4's operation is to achieve length adjustment using threaded transmission to meet different installation spacing requirements. The two threaded rods 10 are screwed into both ends of the double-threaded cylinder 12 via threads. Since the threads at both ends of the double-threaded cylinder 12 have opposite directions of rotation, when the double-threaded cylinder 12 is rotated, the two threaded rods 10 will simultaneously retract into the cylinder or extend outward, thereby quickly adjusting the total length of the entire adjustable support rod 4. The advantages of this design are: a wide adjustment range, adaptable to different distance differences between walls and tower cranes; the threaded transmission has a self-locking function, maintaining stability after adjustment to the required length without additional fixing, preventing length changes during use; and high structural strength, effectively transmitting support force. Combined with the overall triangular support structure, it further enhances the load-bearing capacity and stability of the tooling, while being easy to assemble and disassemble, facilitating transportation and reuse.

[0027] Fixing bolts 11 are rotatably mounted on both sides of the bidirectional threaded cylinder 12. The fixing bolts 11 are rotatably mounted inside the bidirectional threaded cylinder 12 and contact the threaded rod 10. The operating logic of the fixing bolts 11 is that after the length of the adjustable support rod 4 is adjusted, the threaded rod 10 is locked and fixed to the bidirectional threaded cylinder 12. When the length of the adjustable support rod 4 is adjusted to the correct position, the fixing bolts 11 on both sides of the bidirectional threaded cylinder 12 are rotated, so that the fixing bolts 11 are pushed into the threaded cylinder and make tight contact with the surface of the threaded rod 10. The friction between the fixing bolts 11 and the threaded rod 10 locks the position of the threaded rod 10, preventing it from rotating relative to the support rod 10 due to vibration, load or other factors during the support process, which would cause the length of the adjustable support rod 4 to change.

[0028] A first through hole 13 is provided in the middle of the bidirectional threaded cylinder 12, and the first through hole 13 penetrates the bidirectional threaded cylinder 12. The first through hole 13 in the middle of the bidirectional threaded cylinder 12 penetrates the entire cylinder body. Its core function is to provide a force point for adjustment. During operation, tools such as pry bars and wrenches can be inserted into the first through hole 13, and the bidirectional threaded cylinder 12 can be rotated more easily with the help of the leverage of the tools to realize the extension and retraction adjustment of the threaded rod 10. This solves the problem that the surface of the bidirectional threaded cylinder 12 is smooth and difficult to apply force, and reduces the difficulty of adjusting the length of the adjustable support rod 4. Especially when the thread friction of the adjustable support rod 4 increases after being stressed, it can be easily adjusted with the help of tools. The through design of the first through hole 13 allows tools to be inserted from either side, adapting to the operational needs of different installation spaces and improving operational flexibility. At the same time, the structure of the first through hole 13 does not affect the structural strength of the threaded cylinder, ensuring that the load-bearing capacity of the adjustable support rod 4 is not affected.

[0029] The sliding mechanism 7 consists of a sliding plate 8 and a sliding groove 9. The sliding groove 9 is located at one end of the first side plate 6 and the second side plate 14. The sliding plate 8 is installed on both sides of the adjusting plate 16 and slides inside the sliding groove 9. The sliding mechanism 7 provides a smooth sliding guide for the adjusting plate 16. When the adjusting mechanism 18 drives the first side plate 6 and the second side plate 14 to move, the adjusting plate 16 slides synchronously in the sliding groove 9 through the sliding plate 8, so that the adjusting plate 16 always keeps in contact with the surface of the tower crane. The small gap between the sliding plate 8 and the sliding groove 9 ensures no offset during sliding and guarantees adjustment accuracy. The sliding groove 9 limits the sliding plate 8 to prevent the adjusting plate 16 from falling off or misaligning, thus improving structural stability. The smooth sliding contact surface has low friction, ensuring a smooth and uninterrupted adjustment process and reducing adjustment resistance. At the same time, the sliding plate 8 and the sliding groove 9 have good wear resistance and are not easily worn over long-term use, ensuring the service life of the sliding mechanism 7 and the long-term reliability of the adjustment function.

[0030] The working principle and usage process of this utility model: During use, the support device 1 achieves a stable connection and adaptive adjustment between the tower crane and the wall through the coordinated action of multiple components. The fixing component 15 first firmly fixes the first side plate 6, the second side plate 14, and the adjusting plate 16 to the outside of the tower crane, forming a connection base that fits snugly against the tower crane. The adjusting plate 16 can slide flexibly between the first side plate 6 and the second side plate 14 via the sliding mechanism 7. Combined with the drive of the adjusting mechanism 18, it can accurately adapt to the different dimensions and installation positions of different tower cranes, solving the problem of limited adaptability of traditional support fixtures. The adjustable support rod 4 is fixed to the wall and the mounting frame 5 respectively by connecting the mounting plate 2 to the bearings 3 at both ends. Furthermore, the two adjustable support rods 4 on one side of the mounting frame 5 form a triangular structure with the wall. Utilizing the principle of triangular stability, the lateral and vertical forces of the tower crane are evenly transferred to the wall, significantly improving the support strength and anti-overturning ability. During operation, the distance between the first side plate 6 and the second side plate 14 can be finely adjusted through the adjustment mechanism 18, and combined with the length adjustment of the adjustable support rods 4, three-dimensional fine adjustment of the support position can be achieved, ensuring that the tooling fits tightly with the tower crane and the wall, avoiding support loosening caused by uneven force. It is suitable for installation needs under different working conditions, and the triangular support structure can effectively distribute the load, reduce the risk of single-point force, and ensure the stability and safety of the tower crane during operation.

[0031] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
