Description

Technical Field

[0001] This utility model relates to the field of steel plate hoisting technology, and in particular to a steel plate hoisting clamping and fixing device. Background Technology

[0002] Corrugated steel sheets for construction are shaped steel sheets used in building envelopes (roofs, walls) and composite floors. They are coated or plated sheets that are roll-formed and cold-bent into a corrugated cross-section along the width of the sheet. With the increasingly widespread application of steel structures in the construction industry, corrugated steel sheets have become an indispensable and important material in enclosure structures and floor slabs. Corrugated steel sheet hoisting equipment for construction refers to specialized equipment used for hoisting and installing corrugated steel sheets during the construction process.

[0003] Currently, due to the varying lengths and heights of building walls and roofs, steel plates of different sizes are required based on their dimensions. When placing steel plates on the exterior of building walls, their large size and weight necessitate the use of hoisting machines to lift them to the designated location. The existing hoisting method involves interlocking two sets of hoisting wires with a hoisting hook, then attaching the hoisting wires to the outside of the steel plate. This allows the hoisting machine to lift the plate. However, during the movement of the hoisting machine, the plate may slip between the two sets of hoisting wires due to machine swaying or collisions with the building or building materials. This can cause the plate to tilt, shifting its center of gravity and causing it to fall between the two sets of hoisting wires. This can easily damage nearby construction workers and the building, and can also deform the steel plate, rendering it unusable. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a steel plate hoisting, clamping and fixing device, which aims to solve the problems in the prior art.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a steel plate hoisting, clamping, and fixing device, comprising:

[0006] The lifting platform has multiple support plates fixedly installed in a ring on its outer wall. One end of each support plate has a sliding groove that connects to the other end of the plate. A lifting plate for lifting steel plates is slidably installed in the inner cavity of the sliding groove.

[0007] The receiving groove is located inside the lifting plate. A threaded hole is provided at one end of the lifting plate near the receiving groove. A drive threaded rod is installed in the inner cavity of the threaded hole through threaded engagement. The end of the drive threaded rod away from the threaded hole extends into the inner cavity of the receiving groove.

[0008] Multiple bevel gears 1 are fixedly connected at one end to one end of a receiving groove, and multiple bevel gears 2 that mesh with each other are rotatably installed in a ring arrangement in the inner cavity of the receiving groove. A drive shaft for its own rotation is fixedly installed at the end of the bevel gear 2 away from the bevel gear 1.

[0009] As a further description of the above technical solution:

[0010] The lifting plate is designed with an L-shaped structure, and a clamping plate is mounted on the end of the lifting plate away from the sliding groove via a rotating shaft.

[0011] As a further description of the above technical solution:

[0012] Guide strips are fixedly installed on both sides of the lifting plate, and guide grooves that match the guide strips are symmetrically opened on both sides of the inner cavity of the sliding groove.

[0013] As a further description of the above technical solution:

[0014] The inner wall of the clamping plate is fixedly installed with an extrusion plate that presses against the outer wall of the steel plate. The extrusion plate is bent.

[0015] As a further description of the above technical solution:

[0016] The top of the lifting plate has through holes distributed in a ring shape that communicate with the inner cavity of the receiving groove. The ends of multiple drive shafts away from the second bevel gear extend into the inner cavity of the through holes, and drive blocks are fixedly installed at the ends of the multiple drive shafts that extend into the through holes.

[0017] A rocker arm is detachably mounted on the top of the hoisting platform. A drive plate is fixedly mounted on one end of the rocker arm, and a groove that matches the drive block is opened on the end of the drive plate away from the rocker arm.

[0018] As a further description of the above technical solution:

[0019] A lifting frame is fixedly installed on the top of the lifting platform, and a lifting ring that matches the lifting hook is fixedly installed on the top of the lifting frame.

[0020] This utility model has the following beneficial effects:

[0021] In this invention, after the lifting platform is lowered to the designated position, the lifting plate is pulled to slide along the inner cavity of the sliding groove until the distance between the two symmetrically arranged clamps is greater than the length or width of the steel plate. Then, the lifting ring is adjusted to lower the lifting platform until the middle of the opening end of the clamp is at the same horizontal line as the side wall of the steel plate. Next, the lifting plate is pushed to move it closer to the lifting platform until the clamp is fitted onto the outside of the steel plate, thereby achieving a fixed connection between the steel plate and the four clamps. This prevents the steel plate from detaching from the clamps and falling as the hook moves, avoiding injury to surrounding workers and damage to buildings caused by the steel plate falling during the lifting process, and preventing the steel plate from being deformed due to impacts during the lifting process, rendering it unusable.

[0029] 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.

[0030] Reference Figure 1-5 One embodiment of this utility model provides: a steel plate hoisting, clamping, and fixing device, comprising:

[0031] The lifting platform 1 has multiple support plates 3 fixedly installed in a ring on its outer wall. The receiving groove is opened inside the lifting platform 1. The outer wall of the lifting platform 1 has four installation grooves in a ring. The inner cavities of the installation grooves and the receiving grooves are interconnected. One end of the multiple support plates 3 is fixedly connected to the inner wall of the multiple installation grooves, thereby realizing the connection between the support plates 3 and the outer wall of the lifting platform 1.

[0032] A lifting frame 2 is fixedly installed on the top of the lifting platform 1. A lifting ring adapted to the hook is fixedly installed on the top of the lifting frame 2. The lifting frame 2 is set as a U-shaped structure. The outer wall of the lifting ring is fixedly connected to the top of the lifting frame 2. The lifting ring can be sleeved with the lifting hook of the crane, thereby realizing the connection and separation between the lifting platform 1 and the hook.

[0033] One end of the support plate 3 is provided with a sliding groove that communicates with the other end of itself. A lifting plate 4 for lifting the steel plate is slidably installed in the inner cavity of the sliding groove. The lifting plate 4 is designed with an L-shaped structure. One end of the lifting plate 4 is slidably installed in the inner cavity of the sliding groove, while the other end away from the receiving groove extends to the outside of the support plate 3. The sliding groove enables the lifting plate 4 to slide and connect with the support plate 3, while also providing support for the lifting plate 4 and improving the stability of the lifting plate 4 as it slides along its own axis.

[0034] The end of the lifting plate 4 furthest from the sliding groove is fitted with a clamping plate 6 via a rotating shaft. When lifting the steel plate, the lifting ring and the hook are interlocked. At this time, the lifting plate 1 is directly below the hook. By lowering the hook, once the lifting plate 1 has moved to the designated position, the lifting plate 4 is pulled to slide along the inner cavity of the sliding groove until the distance between the two symmetrically arranged clamping plates 6 is greater than the length or width of the steel plate. Then, the lifting ring is adjusted to lower the lifting plate 1 until the middle of the opening end of the clamping plate 6 is at the same horizontal line as the side wall of the steel plate. Immediately afterwards, the lifting plate 4 is pushed to move it closer to the lifting plate 1. The lifting plate 4 is moved until the clamping plate 6 is fitted onto the outside of the steel plate. At this time, the bottom of the lifting plate 1 is parallel to the top of the steel plate, and the lifting plate 1 is located in the middle of the steel plate, so that the center of gravity of the lifting plate 1 coincides with the center of gravity of the steel plate. Then, the moving lifting plate 4 is fixed to prevent the lifting plate 4 from moving again, thereby realizing the fixed connection between the steel plate and the four clamping plates 6. This prevents the steel plate from falling off the clamping plates 6 as the hook moves, avoiding injury to surrounding workers and damage to the building during the lifting process, and preventing the steel plate from being deformed due to impact during the lifting process, making it unusable.

[0035] The clamping plate 6 is designed with a U-shaped structure, allowing it to fit against the side wall of the steel plate. When clamping steel plates of different shapes (such as round and fan-shaped steel plates with curved outer walls), after the clamping plate 6 fits against the outside of the steel plate, until the inner wall of the clamping plate 6 is in contact with the curved surface of the steel plate, the lifting plate 4 continuously moves towards the lifting plate 1, causing the clamping plate 6 to be continuously squeezed by the lifting plate 4 and the outer surface of the steel plate. This causes the clamping plate 6 to rotate continuously through the pivot and one end of the lifting plate 4 until the curved surface of the steel plate is in contact with the middle of the inner wall of the clamping plate 6, thus completing the fitting of the clamping plate 6 against the side wall of the steel plate. This is beneficial for lifting steel plates of different shapes.

[0036] The lifting plate 4 has a threaded hole at one end near the receiving groove. A drive threaded rod 7 is installed in the inner cavity of the threaded hole through threaded engagement. The end of the drive threaded rod 7 away from the threaded hole extends into the inner cavity of the receiving groove. By rotating the drive threaded rod 7 in engagement with the threaded hole, the lifting plate 4 can be moved along the axis of the drive threaded rod 7. By changing the rotation direction of the drive threaded rod 7, the moving direction of the lifting plate 4 can be changed, and the moving lifting plate 4 can be fixed. This is beneficial for accurately adjusting the distance between the clamping plate 6 and the lifting plate 1.

[0037] Multiple bevel gears 13 are fixedly connected at one end to one end of a receiving groove, with multiple drive threaded rods 7 extending to the receiving groove. Multiple bevel gears 12, which mesh with bevel gears 13, are rotatably installed in a ring arrangement inside the receiving groove. A drive shaft 11 for its own rotation is fixedly installed at the end of each bevel gear 12 away from bevel gears 13. Four bevel gears 12 are rotatably installed in a ring arrangement inside the receiving groove. The four bevel gears 12 mesh with the four bevel gears 13. The rotation direction of the four bevel gears 13 can be adjusted individually through the four bevel gears 12, which is beneficial for the four lifting plates 4 to slide independently and for the four clamping plates 6 to clamp the outer wall of quadrilateral steel plates of different sizes.

[0038] Guide bars 5 are fixedly installed on both sides of the lifting plate 4. Guide grooves that are compatible with the guide bars 5 are symmetrically opened on both sides of the inner cavity of the sliding groove. The side of the guide bar 5 away from the lifting plate 4 extends into the interior of the guide groove. Through the cooperation between the guide bar 5 and the guide groove, the sliding trajectory of the lifting plate 4 can be limited, preventing the lifting plate 4 from shaking or deviating when it moves back and forth along the sliding groove by driving the threaded rod 7, thus improving the stability of the lifting plate 4 when moving back and forth.

[0039] The inner wall of the clamping plate 6 is fixedly installed with a pressing plate 8 that presses against the outer wall of the steel plate. The pressing plate 8 is bent and is made of metal spring sheet or metal elastic plate. When the clamping plate 6 is sleeved on the outside of the steel plate, the pressing plate 8 is pressed by the outer wall of the steel plate and bends away from the steel plate. At this time, the pressing plate 8 can press against the outer wall of the steel plate and increase the contact area with the outer wall of the steel plate. This prevents the steel plate from being bumped and slightly shaking during the transfer, and improves the stability of the steel plate during the transfer process.

[0040] The top of the lifting plate 1 has through holes arranged in a ring shape, which communicate with the inner cavity of the receiving groove. The ends of multiple drive shafts 11 away from the second bevel gear 12 extend into the inner cavity of the through holes, and drive blocks 10 are fixedly installed at the ends of the multiple drive shafts 11 extending into the through holes. A rocker arm is detachably installed on the top of the lifting plate 1. A drive disk 9 is fixedly installed at one end of the rocker arm. The end of the drive disk 9 away from the rocker arm has a groove that matches the drive block 10. The shape of the groove and the shape of the drive block 10 are the same, both set as a triangular structure. When the second bevel gear 12 needs to be rotated, the drive disk 9 is inserted into the through hole until the drive block 10 is completely inserted into the groove. Then the rocker arm is turned to realize the rotation of the second bevel gear 12.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
