Description

Technical Field

[0001] This invention relates to an unloading platform, specifically a lifting and unloading platform for transporting and lifting construction materials in power engineering, belonging to the technical field of unloading platforms. Background Technology

[0002] Unloading platforms are temporary operating platforms and frames commonly erected on construction sites. They are mainly used to unload materials after they have been lifted for turnover. They mainly include mobile unloading platforms, ground-mounted unloading platforms, and cantilevered unloading platforms. Cantilevered unloading platforms are mainly used in the construction of high-rise buildings, especially in the construction of large gate chambers in power engineering, where cantilevered unloading platforms are often used for the turnover of building materials.

[0003] Chinese patent titled "A Cantilevered Unloading Platform" (patent number ZL202323166066.1) discloses a cantilevered unloading platform technology. Multiple steel beams are fixed to one end of the unloading plate, providing support and stability. A moving mechanism is located on the side of the unloading plate; controlling this mechanism allows for the smooth movement of the unloading hopper on the plate, sliding it to the desired unloading position. Fixing mechanisms are installed on two steel beams to securely hold the beams and the unloading plate, ensuring the stability and safety of the entire structure. The unloading platform features symmetrically fixed mounting ears on the sides of the unloading bin, with steel wire ropes used to lift the bin. However, while this unloading platform allows for the smooth movement of the unloading bin on the unloading plate, enabling it to slide to the desired unloading position, its overall structure is similar to that of a traditional cantilevered unloading platform. It is an integrated structure and cannot remove the unloading bin from the platform for material transport. It can only transfer the unloaded material to the building interior, requiring manual on-site retrieval and handling, increasing the labor intensity of workers. Therefore, a lifting and unloading platform for transporting building materials in power engineering is proposed. Summary of the Invention

[0026] The embodiments of the present invention have the following advantages due to the adoption of the above technical solutions:

[0027] I. This invention utilizes an unloading assembly to store hoisted building materials. A traction drive mechanism then uses a geared disc to move the unloading base, transferring the materials into the gatehouse. A manual hydraulic pump powers a hydraulic cylinder, causing the piston rod to push a roller to contact the ground, lifting the unloading base and separating the geared disc from the traction drive mechanism. This allows the unloading assembly to transfer the building materials to the desired location for unloading, saving labor intensity and improving work efficiency.

As the unloading base falls, the rollers are retracted into the unloading base, allowing the toothed disc on the outside of the unloading base to connect smoothly with the traction drive mechanism. This enables the connection between the unloading assembly and the traction drive mechanism to be completed quickly, making the operation of the unloading platform more convenient.

[0056] In one embodiment, the hydraulic adjustment mechanism 4 further includes a handle 401, a connecting rod 402, and a sleeve 403;

[0058] Two locking blocks 66 are symmetrically fixedly connected to one side of the enclosure 302, and the outer side wall of the handle 401 is locked to the inner side wall of the locking block 66.

[0059] By pressing down the handle 401, the connecting rod 402 is moved. The moving connecting rod 402 drives the sleeve 403 to provide power to the manual hydraulic pump 404. Then, by repeatedly pressing down the handle 401 and the connecting rod 402, the manual hydraulic pump 404 provides power to the hydraulic cylinder 405. Then, the piston rod of the hydraulic cylinder 405 drives the roller 406 to contact the ground.

[0060] In one embodiment, the traction drive mechanism 5 includes a geared motor 501, a first sprocket 502, a transmission chain 503, a second sprocket 504, a transmission shaft 505, and two traction members 506.

[0061] Among them, the geared motor 501 is installed at the bottom of the inner side wall of the limiting support frame 103, the first sprocket 502 is fixedly connected to the output shaft of the geared motor 501, the transmission shaft 505 is rotatably connected to the adjacent side of the two supporting steel frames 101, the second sprocket 504 is fixedly connected to the middle of the outer side wall of the transmission shaft 505, the inner side wall of the transmission chain 503 is meshed with the outer side walls of the second sprocket 504 and the first sprocket 502, and the two traction members 506 are respectively installed on one side of the two supporting steel frames 101;

[0062] Both traction components 506 include a first traction sprocket 561, a traction chain 562, and a second traction sprocket 563;

[0063] The first traction sprocket 561 is fixedly connected to one side of the outer wall of the drive shaft 505, the second traction sprocket 563 is rotatably connected to one side of the support steel frame 101, the inner wall of the traction chain 562 is meshed with the outer walls of the first traction sprocket 561 and the second traction sprocket 563, and the outer wall of the toothed disc 304 is inserted into the inner wall of the traction chain 562.

[0064] The output shaft of the geared motor 501 drives the first sprocket 502 to rotate. The rotating first sprocket 502 drives the transmission shaft 505 to rotate via the second sprocket 504. The rotating transmission shaft 505 drives the traction chain 562 to move via the geared motor 501. The moving traction chain 562 drives the unloading base 301 to move as a whole via the toothed disc 304.

[0065] In one embodiment, a fixing ring 61 is fixedly connected to one side of the upper surface of each of the two supporting steel frames 101, a threaded cylinder 64 is fixedly connected to one side of the transverse tie rod 205, an adjusting ring 63 is threadedly connected to the inner side wall of the threaded cylinder 64, and a wire rope 62 is fixedly connected between the adjusting ring 63 and the fixing ring 61.

[0066] The steel wire rope 62 is moved by moving the adjusting ring 63. Then, one end of the adjusting ring 63 is inserted into the threaded cylinder 64, and the steel wire rope 62 is moved by rotating the adjusting ring 63 using the thread to tighten the steel wire rope 62.

[0067] In one embodiment, each of the two supporting steel frames 101 has an extension 65 on one side;

[0068] The extension part 65 is used to fix the support steel frame 101 with expansion bolts.

[0069] In operation, the present invention works as follows: First, the movable support steel frame 101 is erected outside the gate chamber building. Then, the movable support rod 202 is inserted into the threaded shaft 201. By rotating the threaded shaft 201, the support rod 202 is fixed to the threaded shaft 201 using threads. Then, by rotating the threaded rod 203, the top plate 204 is moved using threads. The moving top plate 204 presses against the top wall inside the gate chamber building to provide support for one end of the support steel frame 101. Alternatively, the extension part 65 can be used with expansion bolts to pre-fix one side of the support steel frame 101 to the ground inside the gate chamber building. Then, the adjustable bracket 2 is used to reinforce it.

[0070] After the support steel frame 101 is fixed as a whole, the steel wire rope 62 is moved by moving the adjusting ring 63. Then, one end of the adjusting ring 63 is inserted into the threaded cylinder 64, and the steel wire rope 62 is moved by rotating the adjusting ring 63 using the thread to tighten the steel wire rope 62, thereby improving the overall stability of the support steel frame 101 after installation.

[0071] When unloading is required, the output shaft of the geared motor 501 drives the first sprocket 502 to rotate. The rotating first sprocket 502 drives the transmission shaft 505 to rotate via the second sprocket 504. The rotating transmission shaft 505 drives the traction chain 562 to move via the geared motor 501. The moving traction chain 562 drives the unloading base 301 to move to the outside of the gatehouse via the toothed disc 304, so that the hoisted building materials can be directly placed into the enclosure 302 for unloading. After unloading is completed, the output shaft of the geared motor 501 drives the first sprocket 502 to rotate in the opposite direction. The reverse-rotating first sprocket 502 drives the second sprocket 504 to rotate via the transmission chain 503. The rotating second sprocket 504 drives the traction chain 562 to move in the opposite direction via the transmission shaft 505 and the first traction sprocket 561. The reverse-moving traction chain 562 drives the unloading base 301 to move via the toothed disc 304, so as to transfer the building materials into the gatehouse.

[0072] After the building materials have been transferred, pressing down on the handle 401 moves the connecting rod 402. The moving connecting rod 402 drives the sleeve 403 to provide power to the manual hydraulic pump 404. Then, by repeatedly pressing down on the handle 401 and the connecting rod 402, the manual hydraulic pump 404 provides power to the hydraulic cylinder 405. The piston rod of the hydraulic cylinder 405 drives the roller 406 to contact the ground, and the hydraulic cylinder 405 drives the unloading base 301 to rise as a whole, so that the unloading base 301 is lifted and the toothed disc 304 is separated from the traction chain 562. Then, by moving the handle 401, the connecting rod 402, sleeve 403 and manual hydraulic pump 404 drive the unloading base 301 to move as a whole. The roller 406 is used to reduce the friction between the unloading base 301 and the ground, so that the building materials can be quickly transferred to the designated location as needed. Then, by moving the unloading gate 303, one side of the enclosure 302 is opened to remove the building materials from the inside of the enclosure 302.

[0073] After the building materials inside the enclosure 302 are removed, the unloading base 301 is pushed between the two supporting steel frames 101 by moving the handle 401. Then, the piston rod of the hydraulic cylinder 405 is reset by using the manual hydraulic pump 404, so that the unloading base 301 is lowered as a whole during the reset process, driving the toothed disc 304 to insert into the traction chain 562, quickly connecting the unloading assembly 3 and the traction drive mechanism 5. The piston rod continues to reset, driving the roller 406 to retract into the mounting hole 305 to prevent the roller 406 from interfering with the movement of the unloading base 301.

[0074] The handle 401 is limited to one side of the enclosure 302 by the set block 66.

[0075] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in the present invention, and these should all be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
