Description

Technical Field

[0001] This utility model relates to the field of beam lifting machine technology, and more specifically to a high-stability hydraulic beam lifting machine. Background Technology

[0002] A beam lifting machine is a mechanical device used for moving and installing large precast beams. It can easily lift and move beam structures weighing several tons. Beam lifting machines are designed to improve construction efficiency, reduce manpower requirements, and ensure safety during beam installation in building projects.

[0003] Currently, the commonly used bridge hoisting machines primarily use steel wire ropes to lift and transport bridges. However, during the hoisting process, the bridge will sway continuously due to the swing of the steel wire ropes, which may cause the bridge to collide with the bridge hoisting machine, thus posing certain safety hazards and affecting the stability of the bridge transported by the bridge hoisting machine.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-2This utility model provides a high-stability hydraulic lifting beam machine, including two support frames 1, a main beam 2 located between the support frames 1, a winding device installed on the main beam 2, and a steel wire rope 3 located below the main beam 2. The specific structure and working principle of the winding device are well known to those skilled in the art, and therefore will not be described in detail in this embodiment. The bottom of the support frame 1 is provided with rollers (not shown in the figure), and the main beam 2 is provided with a stabilizing device. The stabilizing device includes a fixing pipe 4 fixed to the steel wire rope 3, a lifting frame installed on the main beam 2 and capable of being raised and lowered, and a limiting component located between the lifting frame and the fixing pipe 4. The limiting component consists of a limiting plate 5 fixed to the fixing pipe 4, a limiting hole 6 provided on the limiting plate 5, and a limiting rod 7 installed at the bottom end of the lifting frame. The lifting frame is raised and lowered by a driving device, which includes a motor 10 installed on the main beam 2 and a lead screw 11 connected to the output shaft of the motor 10. The lead screw 11 passes through and is threadedly connected to the lifting frame. The motor 10 drives the lead screw 11 to rotate. Because the lead screw 11 is threadedly connected to the lifting frame, the lifting movement of the lifting frame can be realized. In addition to the structure of motor 10 and lead screw 11, the lifting function can also be realized by other structures such as hydraulic cylinder 12.

[0021] During the operation of the beam lifting machine, the lifting frame is driven to descend by the motor 10. The lifting frame moves the limit rod 7 downward until the limit rod 7 is inserted into the limit hole 6. Through the synergistic effect of the limit rod 7 and the limit hole 6, the swing of the wire rope 3 is effectively prevented, thereby improving the stability of the beam lifting machine during transportation.

[0022] To enhance the stability of the wire rope 3, the limiting disc 5 is circumferentially equipped with several limiting holes 6, while the bottom of the lifting frame is circumferentially equipped with corresponding limiting rods 7. The specific number of limiting holes 6 and limiting rods 7 can be adjusted according to actual needs. In this embodiment, the number of limiting holes 6 and limiting rods 7 is set to four. Through the interaction of these four sets of limiting holes 6 and limiting rods 7, the stability of the wire rope 3 is further improved.

[0023] In this embodiment, a mounting plate 8 is disposed at the bottom of the lifting frame, and a limiting rod 7 is placed below the mounting plate 8. The mounting plate 8 has a through hole 9 for the wire rope 3 to pass through, and the diameter of the through hole 9 is larger than the diameter of the wire rope 3. The mounting plate 8 is not only used for installing the limiting rod 7, but also, under the action of the limiting hole 6, prevents large-scale swaying of the middle of the wire rope 3, thereby further improving the stability of the wire rope 3.

[0024] To facilitate the disassembly and replacement of the limiting rod 7, this embodiment features a detachable connection between the limiting rod 7 and the mounting plate 8. The connection method between the limiting rod 7 and the mounting plate 8 is not limited to a threaded connection; other suitable connection methods can also be used. To ensure a smoother assembly process between the limiting rod 7 and the limiting hole 6, the end of the limiting rod 7 is designed with a chamfered structure. To prevent excessive wear on the perforation 9 when the lifting machine is not in operation, a wear-resistant sleeve is installed inside the perforation 9. This wear-resistant sleeve is made of wear-resistant material to enhance the wear resistance of the inner wall of the perforation 9.

[0025] In this embodiment, a pre-positioning device is provided on the main beam 2. This pre-positioning device includes a hydraulic cylinder 12 mounted on the main beam 2, and a positioning clamp located at the bottom of the hydraulic cylinder 12 and below the main beam 2. The positioning clamp consists of a crossbar connected to the output end of the hydraulic cylinder 12 and inclined rods 14 arranged on both sides of the crossbar. The inclined rods 14 have an "eight"-shaped structure, which can accommodate precast beams of different widths, and are located between the limiting rod 7 and the limiting hole 6. To pre-position the precast beam, the hydraulic cylinder 12 can drive the positioning clamp to move downwards until the inclined rods 14 on both sides of the positioning clamp contact the precast beam, thereby achieving pre-positioning of the precast beam. This prevents the wire rope 3 from causing the limiting disc 5 to swing before the limiting rod 7 and the limiting hole 6 are assembled, thus preventing interference with the assembly of the limiting rod 7 and the limiting hole 6. After the limiting rod 7 and the limiting hole 6 are assembled, the hydraulic cylinder 12 will drive the positioning clamp to reset.

It should also be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting.

However, those skilled in the art will understand that the present invention can be implemented without the aforementioned one or more specific details or may be implemented using other methods, components, materials, etc.
