Description

Technical Field

[0001] This utility model relates to the field of cement pole production equipment, specifically a lifting device for cement pole production. Background Technology

[0002] Cement poles, with their durability, safety, and versatility, have become a core component of modern infrastructure. They not only ensure the smooth transmission of energy and information but also promote sustainable social development, serving as an indispensable cornerstone in the processes of urbanization and industrialization. During the production of cement poles, lifting equipment is required for their hoisting and transportation.

[0003] In existing technologies, the lifting and transfer of cement poles during the production process is usually achieved using small gantry cranes. Gantry cranes, also known as portal cranes, typically consist of a main structural frame, a traveling mechanism, and a hoisting mechanism. The main structural frame refers to the main body composed of a main beam, legs, and a lower crossbeam. The traveling mechanism is divided into a trolley traveling mechanism (the structure that drives the entire gantry crane to move) and a trolley traveling mechanism (the structure that drives the hoisting trolley to move laterally on the main beam). The trolley traveling mechanism of a small gantry crane is usually relatively simple, consisting of four sets of rollers, and is driven manually. The hoisting mechanism consists of a motor and reducer, wire rope and pulley blocks, hooks or lifting devices, etc., and is responsible for lifting and lowering goods. Gantry cranes have many advantages such as a large coverage area, flexible operation, strong load-bearing capacity, and strong adaptability, making them the best choice for lifting devices in cement pole production.

[0004] However, in existing small gantry cranes, the height at which the rollers lift the gantry crane is not adjustable. When using a small gantry crane to lift and transport cement poles on a slope, the gantry crane will be tilted during the ascent and descent. Since the cement poles are relatively heavy, this can easily cause the gantry crane to tip over, and the cement poles will fall to the ground and be damaged. In addition, the rollers of the gantry crane are subjected to enormous pressure during long-term use, which often results in a shorter service life. In existing technology, the rollers are installed at the bottom of the gantry crane with screws. When replacing the rollers, a jack is needed to lift the gantry crane to suspend the damaged rollers, and then the screws are removed and reinstalled with a screwdriver to replace the rollers. This means that roller replacement is impossible without jacks prepared in advance. Utility Model Content

[0005] The purpose of this utility model is to provide a lifting device for cement pole production to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lifting device for cement pole production, comprising: a gantry crane body and rollers; a hydraulic strut mechanism is fixed on the surface of the gantry crane body; a hydraulic rod insertion groove is formed on the surface of the gantry crane body; the hydraulic rod of the hydraulic strut mechanism is movably inserted into the hydraulic rod insertion groove; a first pulley mounting block is fixed at the bottom end of the hydraulic rod of the hydraulic strut mechanism; a second pulley mounting block is mounted on the surface of the first pulley mounting block; a portion of a roller mounting groove is formed on the surfaces of the first pulley mounting block and the second pulley mounting block; a roller mounting rod is fixed at the top end of the rollers; and the roller mounting rod is rotatably connected in the roller mounting groove.

[0007] Preferably, a push screw hole is provided on the surface of the gantry crane body, and a push screw is installed in the push screw hole by a threaded connection, with a top plate fixed at the bottom end of the push screw.

[0008] Preferably, the roller mounting groove has a "T"-shaped circular groove structure, and the roller mounting rod cooperates with the roller mounting groove.

[0009] Preferably, the surface of the first pulley mounting block has a mounting screw hole, and the surface of the second pulley mounting block has a mounting screw rotatably connected to it. The mounting screw is installed in the mounting screw hole via a threaded connection. Preferably, the surface of the second pulley mounting block has a nut groove, the nut of the mounting screw is rotatably connected in the nut groove, and an anti-loosening sleeve is movably inserted into the nut groove. The surface of the anti-loosening sleeve has a nut groove, and the nut of the mounting screw is movably inserted into the nut groove. The nut of the mounting screw has a hexagonal prism structure.

[0010] The nut groove mates with the nut of the mounting screw.

[0011] Preferably, the nut groove has a rectangular groove structure, and the anti-loosening sleeve mates with the nut groove.

[0012] Preferably, an anti-slip pad is fixed on the surface of the anti-loosening sleeve, and the anti-slip pad abuts against the inner wall of the nut groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The lifting device for cement pole production proposed in this utility model allows for the following operation: When a gantry crane is needed to lift a cement pole up or down a slope, the hydraulic rods of the two sets of hydraulic strut mechanisms at the lower end of the gantry crane extend as the crane moves up or down the slope. This causes the two sets of rollers at that end to lift that end of the gantry crane, thus restoring balance to both ends and preventing the crane from tipping over. Furthermore, if the rollers become damaged during long-term use, tightening the push screw, through the threaded connection between the push screw hole and the push screw, allows the top plate to contact the ground. Contact, push the screw and top plate to replace the broken roller to support the gantry crane body. Then, remove the second pulley mounting block to expose a notch on the side of the roller mounting slot. The roller mounting rod can then be easily removed from the notch on the side of the roller mounting slot, completing the removal of the old roller. Then, insert the roller mounting rod on the surface of the new roller back into the roller mounting slot through the notch. Reinstall the second pulley mounting block on the surface of the first pulley mounting block to restore the roller mounting slot to its integrity. The roller can then be replaced without a jack.

[0021] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1: Please refer to Figures 1-5 This utility model provides a technical solution: a lifting device for cement pole production, comprising: a gantry crane body 1 and rollers 4. A hydraulic strut mechanism 2 is fixed on the surface of the gantry crane body 1. A hydraulic rod insertion groove 7 is formed on the surface of the gantry crane body 1. The hydraulic rod of the hydraulic strut mechanism 2 is movably inserted into the hydraulic rod insertion groove 7. A first pulley mounting block 3 is fixed to the bottom end of the hydraulic rod of the hydraulic strut mechanism 2. A second pulley mounting block 9 is mounted on the surface of the first pulley mounting block 3. A portion of a roller mounting groove 5 is provided on the surface of each of the pulley mounting block 3 and the second pulley mounting block 9. A roller mounting rod 6 is fixed to the top of the roller 4 and is rotatably connected in the roller mounting groove 5. A push screw hole 10 is provided on the surface of the gantry crane body 1. A push screw 11 is installed in the push screw hole 10 by threaded connection. A top plate 8 is fixed to the bottom end of the push screw 11. The roller mounting groove 5 has a "T"-shaped circular groove structure. The roller mounting rod 6 cooperates with the roller mounting groove 5.

[0023] In actual use, when the gantry crane body 1 needs to suspend a cement pole up or down a slope, as the gantry crane body 1 moves up or down the slope, the hydraulic rods of the two sets of hydraulic strut mechanisms 2 at the lower end of the gantry crane body 1 extend, causing the two sets of rollers 4 at this end to lift this end of the gantry crane body 1, thereby restoring the balance of both ends of the gantry crane body 1 and preventing the gantry crane body 1 from tipping over. Furthermore, when the rollers 4 are damaged during long-term use, the push screw 11 is tightened. Under the threaded connection between the push screw hole 10 and the push screw 11, the top plate 8 contacts the ground, and the push screw 1... The top plate 8 and the second pulley mounting block 9 can replace the broken roller 4 to support the gantry crane body 1. Then, the second pulley mounting block 9 is removed, exposing a notch on the side of the roller mounting groove 5. The roller mounting rod 6 can then be easily removed from the notch on the side of the roller mounting groove 5, completing the removal of the old roller 4. Then, the roller mounting rod 6 on the surface of the new roller 4 is inserted back into the roller mounting groove 5 through the notch. The second pulley mounting block 9 is then reinstalled on the surface of the first pulley mounting block 3 to restore the roller mounting groove 5 to its original state. Thus, the replacement of the roller 4 can be completed without the need for a jack.

[0024] Example 2: Based on Example 1, in order to achieve a stable installation of the first pulley mounting block 3 and the second pulley mounting block 9, a mounting screw hole 12 is provided on the surface of the first pulley mounting block 3, and a mounting screw 13 is rotatably connected to the surface of the second pulley mounting block 9. The mounting screw 13 is installed in the mounting screw hole 12 by a threaded connection. A nut groove 14 is provided on the surface of the second pulley mounting block 9, and the nut of the mounting screw 13 is rotatably connected in the nut groove 14. An anti-loosening sleeve 15 is movably inserted into the nut groove 14. A nut groove 16 is formed on the surface of the anti-loosening sleeve 15. The nut of the mounting screw 13 is movably inserted into the nut groove 16. The nut of the mounting screw 13 has a hexagonal prism structure. The nut groove 16 mates with the nut of the mounting screw 13. The nut groove 14 has a rectangular groove structure. The anti-loosening sleeve 15 mates with the nut groove 14. An anti-slip pad 17 is fixed on the surface of the anti-loosening sleeve 15 and abuts against the inner wall of the nut groove 14.

[0025] The second pulley mounting block 9 is installed via a threaded connection between the mounting screw hole 12 and the mounting screw 13. After the mounting screw 13 is tightened in the mounting screw hole 12, the anti-loosening sleeve 15 is inserted into the nut groove 14, so that the nut of the mounting screw 13 is inserted into the nut groove 16. The nut groove 14 is a rectangular groove, which prevents the anti-loosening sleeve 15 from rotating in the nut groove 14. This, in turn, circumferentially limits the nut of the mounting screw 13 in the nut groove 16, thereby achieving the function of the mounting screw 13 and the mounting screw... The anti-loosening function of the threads between holes 12 ensures a stable installation between the second pulley mounting block 9 and the first pulley mounting block 3. At the same time, the anti-loosening sleeve 15 is limited by the nut of the mounting screw 13, so that the anti-loosening sleeve 15 and the anti-slip pad 17 fixed on the surface of the anti-loosening sleeve 15 are tightly attached to the inner wall of the nut groove 14. The anti-slip pad 17 is made of rough rubber material, which generates a large friction between the anti-slip pad 17 and the inner wall of the nut groove 14, preventing the anti-loosening sleeve 15 from sliding out of the nut groove 14.

[0026] In actual use, when the gantry crane body 1 needs to lift a cement pole up or down a slope, as the gantry crane body 1 moves up or down the slope, the hydraulic rods of the two sets of hydraulic strut mechanisms 2 at the lower end of the gantry crane body 1 extend, causing the two sets of rollers 4 at this end to lift this end of the gantry crane body 1, thereby restoring the balance of both ends of the gantry crane body 1 and preventing the gantry crane body 1 from tipping over. Furthermore, when the rollers 4 are damaged during long-term use, the push screw 11 is tightened, and the threaded connection between the push screw hole 10 and the push screw 11 is activated. Lower the top plate 8 to contact the ground. The jacking screw 11 and the top plate 8 can then replace the broken roller 4 to support the gantry crane body 1. After that, remove the second pulley mounting block 9 to expose a notch on the side of the roller mounting groove 5. Then, the roller mounting rod 6 can be easily removed from the notch on the side of the roller mounting groove 5, completing the removal of the old roller 4. Then, insert the roller mounting rod 6 from the surface of the new roller 4 back into the roller mounting groove 5 through the notch. Finally, reinstall the second pulley mounting block 9 onto the surface of the first pulley mounting block 3. By restoring the roller mounting slot 5 to its original position, the roller 4 can be replaced without a jack. The second pulley mounting block 9 is installed via a threaded connection between the mounting screw hole 12 and the mounting screw 13. After the mounting screw 13 is tightened in the mounting screw hole 12, the anti-loosening sleeve 15 is inserted into the nut groove 14, so that the nut of the mounting screw 13 is inserted into the nut groove 16. The nut groove 14 is a rectangular groove, which prevents the anti-loosening sleeve 15 from rotating in the nut groove 14, thereby ensuring that the nut of the mounting screw 13 is circumferentially fixed in the nut groove 16. The anti-loosening sleeve 15 is limited by the nut of the mounting screw 13, thereby preventing the threads between the mounting screw 13 and the mounting screw hole 12 from loosening, and realizing the stable installation between the second pulley mounting block 9 and the first pulley mounting block 3. At the same time, the anti-loosening sleeve 15 is limited by the nut of the mounting screw 13, so that the anti-loosening sleeve 15 and the anti-slip pad 17 fixed on the surface of the anti-loosening sleeve 15 are tightly attached to the inner wall of the nut groove 14. The anti-slip pad 17 is made of rough rubber material, which generates a large friction between the anti-slip pad 17 and the inner wall of the nut groove 14, preventing the anti-loosening sleeve 15 from sliding out of the nut groove 14.
