Description

Technical Field

[0001] The invention relates to the technical field of steel structure prefabricated frame installation, in particular to an adjustable unloading device for installing a steel structure prefabricated frame and a construction method thereof. Background Art

[0002] In the modular construction of steel structures, in order to ensure the smooth installation of the frame structure, the steel structure frame is divided into two frames, and the frame unit modules are welded and bolted in the prefabrication factory to control welding deformation, and the steel beams and their supporting secondary beams and supports are connected as a whole, and lifted to the frame column node installation position at one time for horizontal pre-assembly. After the manned work platform of the elevator is in place, it is installed and connected to complete the overall installation of the structural frame.

[0003] Today's unloading device is mainly composed of four groups of trapezoidal blocks, upper, lower, left and right, which are combined by a limit screw and an adjusting screw. Today's unloading device adjusts the position of the left and right groups of trapezoidal blocks by rotating the position of the threaded block above the adjusting screw, thereby driving the upper threaded block to move. Since the rotation of the threaded block is mostly manual, the force-bearing surface of the surface of the threaded block is wider, which increases the degree of fatigue of the workers when rotating the threaded block. Secondly, since the adjusting screw is exposed to the outside world, the outer wall of the screw is prone to dust and rust. When the device is disassembled after use, the dust and rust on the outer wall of the screw are likely to affect the normal movement of the threaded block. Secondly, when the adjusting screw is inserted into the device and the threaded block is put on the outer wall of the adjusting screw for adjustment, the adjusting screw will slide back and forth inside the device, requiring workers to constantly adjust the position of the screw, which increases the cumbersomeness of workers installing the device.

[0014] According to another aspect of the present invention, there is provided a construction method of an adjustable unloading device for installing a prefabricated steel structure frame, comprising the following steps: S1: Place the left trapezoidal block and the right trapezoidal block on top of the bottom trapezoidal block, and place the top trapezoidal block on top of the left trapezoidal block and the right trapezoidal block. First, put the limiting threaded rod into the first limiting sleeve and the second limiting sleeve, and put the limiting threaded sleeve on the outer wall of the limiting threaded rod to limit the limiting threaded rod. Insert the adjusting threaded rod into the left and right plug holes, and put the adjusting threaded sleeve on the outer wall of the adjusting threaded rod through the adjusting threaded groove. Hold the handle and rotate it. The rotation of the handle drives the adjusting threaded sleeve to rotate, and then move by adhering to the outer wall of the adjusting threaded rod through the adjusting threaded groove, so that the left trapezoidal block and the right trapezoidal block are pushed to move respectively through the gasket, and then the left trapezoidal block and the right trapezoidal block are adjusted. The position of the shaped block, after the position adjustment is completed, the flip handle drives the rotating rod to rotate through the fixed plate, and when the rotating rod rotates, the outer wall of the rotating rod squeezes the inner wall of the clamping groove, and then the clamping block is squeezed, and the clamping block is squeezed to squeeze the return spring, so that the clamping blocks are expanded to provide space for the rotation of the rotating rod, so that the handle is flipped to the inside of the storage groove with the rotating rod, and then the handle is stored. When the handle needs to be unfolded, the handle is flipped out from the inner wall of the storage groove, and then the outer wall of the rotating rod squeezes the inclined surface of the clamping block, so that the rotating rod enters the inside of the clamping groove, and the clamping block is driven to clamp the rotating rod through the reset of the return spring, thereby stabilizing the handle; S2: When the adjusting thread sleeve rotates and moves, the circular cleaning brush is driven to move along the outer wall of the adjusting thread rod, thereby cleaning the outer wall of the adjusting thread rod. Lubricating oil is injected into the lubricating oil rack through the oil filling port. When the movable rack rotates and moves, the lubricating oil rack is driven to move accordingly, thereby driving the arc surface of the semicircular block to contact the protruding thread of the outer wall of the adjusting thread rod. The semicircular block is squeezed away from the inside of the oil discharge port by the thread, and at the same time drives the receiving rod to squeeze the connecting spring, so that the lubricating oil in the oil storage tank flows to the outer wall of the adjusting thread rod. When the non-moving surface of the semicircular block is no longer in contact with the thread, the semicircular block is driven to block the inner wall of the oil discharge port again through the reset of the connecting spring. S3: While the adjusting threaded rod is inserted into the left and right insertion holes, one end of the adjusting threaded rod squeezes the inclined surface of the trapezoidal limit block. The trapezoidal limit block is squeezed against the squeezing spring, so that the trapezoidal limit block enters the interior of the anti-slip frame. As the adjusting threaded rod moves, the inclined groove moves to the top of the trapezoidal limit block. The trapezoidal limit block is moved upward by resetting the squeezing spring, so that the top end of the trapezoidal limit block is stuck in the inclined groove, thereby stabilizing the adjusting threaded rod.

[0015] Compared with the prior art, the present invention has the beneficial effects.

[0016] 1. Place the left trapezoidal block and the right trapezoidal block above the bottom trapezoidal block, and the top trapezoidal block above the left trapezoidal block and the right trapezoidal block. First, put the limiting threaded rod into the first limiting sleeve and the second limiting sleeve, and put the limiting threaded sleeve on the outer wall of the limiting threaded rod to limit the limiting threaded rod. Insert the adjusting threaded rod into the left and right plug holes, and put the adjusting threaded sleeve on the outer wall of the adjusting threaded rod through the adjusting threaded groove. Hold the handle and rotate it. The handle rotates to drive the adjusting threaded sleeve to rotate, and then move by the adjusting threaded groove attached to the outer wall of the adjusting threaded rod, so as to push the left trapezoidal block and the right trapezoidal block to move respectively through the gasket, and then adjust the position of the left trapezoidal block and the right trapezoidal block. After the position adjustment is completed, turn the handle to drive the rotating rod The fixing plate is rotated, and when the rotating rod is rotated, the outer wall of the rotating rod squeezes the inner wall of the clamping groove, and then the clamping block is squeezed, and the clamping block is squeezed to squeeze the return spring, so that the clamping blocks are expanded to provide space for the rotating rod to rotate, so that the handle is flipped to the inside of the storage groove along with the rotating rod, and then the handle is stored. When the handle needs to be unfolded, the handle is flipped out from the inner wall of the storage groove, and then the outer wall of the rotating rod squeezes the inclined surface of the clamping block, so that the rotating rod enters the inside of the clamping groove, and the clamping block is driven to clamp the rotating rod through the reset of the return spring, thereby stabilizing the handle. The unfolding of the handle facilitates the staff to rotate the adjusting threaded sleeve, and the storage of the handle reduces the influence of the unfolding handle on the use of the device.

[0017] 2. When the adjusting thread sleeve rotates and moves, the circular ring cleaning brush is driven to move along the outer wall of the adjusting thread rod, thereby cleaning the outer wall of the adjusting thread rod, and the lubricating oil is injected into the lubricating oil rack through the oil filling port. When the movable rack rotates and moves, the lubricating oil rack is driven to move accordingly, thereby driving the arc surface of the semicircular block to contact the protruding thread on the outer wall of the adjusting thread rod. The semicircular block is squeezed away from the inside of the oil drain port by the thread, and at the same time, the receiving rod is driven to squeeze the connecting spring, so that the lubricating oil in the oil storage tank flows to the outer wall of the adjusting thread rod. When the plane of the semicircular block does not contact the thread, the semicircular block is driven to block the inner wall of the oil drain port again through the reset of the connecting spring, and the dust and rust on the outer wall of the adjusting thread rod are cleaned by the circular ring cleaning brush. At the same time, the lubrication of the movement of the adjusting thread sleeve is increased by the outflowing lubricating oil.

[0018] 3. When the adjusting threaded rod is inserted into the left and right insertion holes, one end of the adjusting threaded rod squeezes the inclined surface of the trapezoidal limit block. The trapezoidal limit block is squeezed against the extrusion spring, so that the trapezoidal limit block enters the interior of the anti-slip frame. As the adjusting threaded rod moves, the inclined groove is driven to move above the trapezoidal limit block. The trapezoidal limit block is driven upward by the resetting of the extrusion spring, so that the top end of the trapezoidal limit block is stuck in the inclined groove, thereby stabilizing the adjusting threaded rod. The lifting of the trapezoidal limit block increases the stability of the adjusting threaded rod after insertion, and avoids the sliding of the adjusting threaded rod during the installation of the device.

[0033] Another typical embodiment of the present invention provides a construction method of an adjustable unloading device for installing a prefabricated steel structure frame, comprising the following steps: S1: Place the left trapezoidal block 301 and the right trapezoidal block 303 on top of the bottom trapezoidal block 101, and place the top trapezoidal block 103 on top of the left trapezoidal block 301 and the right trapezoidal block 303. First, place the limiting threaded rod 203 into the first limiting sleeve 201 and the second limiting sleeve 202, and then put the limiting threaded sleeve 204 on the outer wall of the limiting threaded rod 203 to limit the limiting threaded rod 203. Insert the adjusting threaded rod 305 into the left insertion hole 302. The adjusting thread sleeve 401 is placed on the outer wall of the adjusting thread rod 305 through the adjusting thread groove 402, and the handle 406 is held and rotated. The adjusting thread sleeve 401 is rotated by rotating the handle 406, and then the adjusting thread sleeve 401 is moved by the adjusting thread groove 402 attached to the outer wall of the adjusting thread rod 305, thereby pushing the left trapezoidal block 301 and the right trapezoidal block 303 to move respectively through the gasket 306, thereby adjusting the left trapezoidal block 301 and the right trapezoidal block 303. The position of the shaped block 303 is adjusted. After the position adjustment is completed, the flip handle 406 drives the rotating rod 405 to rotate through the fixed plate 404. When the rotating rod 405 rotates, the outer wall of the rotating rod 405 squeezes the inner wall of the clamping groove 505, and then the clamping block 504 is squeezed. The clamping block 504 is squeezed to squeeze the return spring 503, so that the clamping blocks 504 are expanded to provide a space for the rotating rod 405 to rotate, so that the handle 406 is flipped to the inside of the receiving groove 403 with the rotating rod 405, and then the handle 406 is stored. When the handle 406 needs to be unfolded, the handle 406 is flipped out from the inner wall of the receiving groove 403, and then the outer wall of the rotating rod 405 squeezes the inclined surface of the clamping block 504, so that the rotating rod 405 enters the inside of the clamping groove 505, and the reset of the return spring 503 drives the clamping block 504 to clamp the rotating rod 405, thereby stabilizing the handle 406. S2: When the adjusting threaded sleeve 401 rotates and moves, the annular cleaning brush 603 is driven to move along the outer wall of the adjusting threaded rod 305, thereby cleaning the outer wall of the adjusting threaded rod 305. Lubricating oil is injected into the lubricating oil rack 605 through the oil filling port 607. When the movable rack 601 rotates and moves, the lubricating oil rack 605 is driven to move accordingly, thereby driving the arc surface of the semicircular block 705 to contact the protruding thread on the outer wall of the adjusting threaded rod 305. The semicircular block 705 is squeezed away from the inside of the oil discharge port 610 by the thread, and at the same time drives the storage rod 704 to squeeze the connecting spring 703, so that the lubricating oil in the oil storage tank 606 flows to the outer wall of the adjusting threaded rod 305. When the moving surface of the semicircular block 705 is no longer in contact with the thread, the semicircular block 705 is driven to block the inner wall of the oil discharge port 610 again through the reset of the connecting spring 703. S3: When the adjusting threaded rod 305 is inserted into the left and right sockets 302 and 304, one end of the adjusting threaded rod 305 squeezes the inclined surface of the trapezoidal limit block 804. The trapezoidal limit block 804 is squeezed and squeezes the squeezing spring 803, so that the trapezoidal limit block 804 enters the anti-slip frame 801. As the adjusting threaded rod 305 moves, the inclined groove 307 is driven to move above the trapezoidal limit block 804. The trapezoidal limit block 804 is moved upward by resetting the squeezing spring 803, so that the top end of the trapezoidal limit block 804 is stuck in the inclined groove 307, thereby stabilizing the adjusting threaded rod 305.

10. The construction method of the adjustable unloading device for installing a prefabricated steel structure frame according to claim 1 comprises the following steps: S1: Place the left trapezoidal block (301) and the right trapezoidal block (303) above the bottom trapezoidal block (101), and place the top trapezoidal block (103) above the left trapezoidal block (301) and the right trapezoidal block (303). First, place the limiting threaded rod (203) inside the first limiting sleeve (201) and the second limiting sleeve (202), and then put the limiting threaded sleeve (204) on the outer wall of the limiting threaded rod (203) to limit the position of the limiting threaded rod (203). Insert the adjusting threaded rod (305) into the left insertion hole (302). ) and the right insertion hole (304), the adjusting thread sleeve (401) is sleeved on the outer wall of the adjusting thread rod (305) through the adjusting thread groove (402), and the handle (406) is held and rotated. The rotation of the handle (406) drives the adjusting thread sleeve (401) to rotate, and then the adjusting thread sleeve (401) moves along the outer wall of the adjusting thread rod (305) through the adjusting thread groove (402), thereby pushing the left trapezoidal block (301) and the right trapezoidal block (303) to move respectively through the gasket (306), thereby adjusting the left trapezoidal block (301) and the right trapezoidal block (303). The position of the shaped block (303) is adjusted. After the position adjustment is completed, the flip handle (406) drives the rotating rod (405) to rotate through the fixed plate (404). When the rotating rod (405) rotates, the outer wall of the rotating rod (405) presses the inner wall of the clamping groove (505), and then the clamping block (504) is squeezed. The clamping block (504) is squeezed to squeeze the return spring (503), so that the clamping blocks (504) are expanded to provide space for the rotating rod (405) to rotate, so that the handle (406) rotates with the rotation. The rod (405) is turned over to the inside of the receiving groove (403), thereby storing the handle (406). When the handle (406) needs to be unfolded, the handle (406) is turned out from the inner wall of the receiving groove (403), and then the outer wall of the rotating rod (405) presses the inclined surface of the clamping block (504), so that the rotating rod (405) enters the inside of the clamping groove (505), and the clamping block (504) is driven to clamp the rotating rod (405) through the reset of the reset spring (503), thereby stabilizing the handle (406); S2: When the adjusting threaded sleeve (401) rotates and moves, the circular cleaning brush (603) is moved along the outer wall of the adjusting threaded rod (305), thereby cleaning the outer wall of the adjusting threaded rod (305). Lubricating oil is injected into the lubricating oil rack (605) through the oil filling port (607). When the movable rack (601) rotates and moves, the lubricating oil rack (605) is moved accordingly, thereby driving the arc surface of the semicircular block (705) and the adjusting threaded rod (305) to move. 05) The semicircular block (705) is squeezed by the thread and moves away from the inside of the oil discharge port (610), and at the same time drives the receiving rod (704) to squeeze the connecting spring (703), so that the lubricating oil in the oil storage tank (606) flows to the outer wall of the adjusting threaded rod (305). When the non-moving surface of the semicircular block (705) is no longer in contact with the thread, the semicircular block (705) is driven by the reset of the connecting spring (703) to block the inner wall of the oil discharge port (610) again; S3: While the adjusting threaded rod (305) is inserted into the left insertion hole (302) and the right insertion hole (304), one end of the adjusting threaded rod (305) presses the inclined surface of the trapezoidal limit block (804), and the trapezoidal limit block (804) is pressed against the pressing spring (803), so that the trapezoidal limit block (804) enters the interior of the anti-slip frame (801). As the adjusting threaded rod (305) moves, the inclined groove (307) moves to the top of the trapezoidal limit block (804), and the trapezoidal limit block (804) is driven to move upward by the resetting of the pressing spring (803), so that the top end of the trapezoidal limit block (804) is stuck in the interior of the inclined groove (307), thereby stabilizing the adjusting threaded rod (305).
