Description

Technical Field

[0001] The invention relates to the technical field of concrete hoisting, in particular to a concrete hoisting device for building construction. Background Art

[0002] Hoisting refers to the general term for installing and positioning equipment by means of a crane or hoist. During the process of maintenance or transportation of materials, a crane is used to lift workpieces, materials, and equipment, causing their position to change. The process requires the assistance of hoisting equipment.

[0003] In construction, hoisting and stacking of concrete blocks is a common operation process. Traditional hoisting devices mostly use fixed frame structures, and hoisting is achieved by welding hanging ears or fixed hooks. However, such devices have the following problems

[0004] (1) After the current aerated concrete blocks are hoisted and transported to another location, they need to be manually moved out of the hoisting equipment by staff, resulting in high labor intensity. At the same time, manual transportation takes a long time, which greatly reduces work efficiency and has poor use effect.

[0005] (2) The friction resistance between the concrete blocks and the frame is large, manual pushing and pulling is laborious, and mechanized assistance is insufficient.

[0006] (3) The welded hanging ears are easy to become unsoldered and the hoisting position cannot be adjusted, making it difficult to adapt to blocks with different center of gravity distributions. Summary of the invention

[0007] In view of the deficiencies in the prior art, the present invention provides a concrete hoisting device for building construction, which solves the above-mentioned problems.

[0008] To achieve the above objectives, the present invention is implemented through the following technical solutions: A concrete hoisting device for construction, comprising a placing frame for stacking concrete blocks and an auxiliary frame arranged below the placing frame, the inner cavity of the placing frame is provided with a lifting connection assembly connected to a hook, the placing frame is slidably arranged above the auxiliary frame through a buffer mechanism, and the inner cavity of the auxiliary frame is provided with a power-assisting mechanism for assisting the movement of concrete blocks;

[0009] The power-assisting mechanism comprises a fixing seat fixed on the inner cavity surface of the auxiliary frame, the inner cavity of the fixing seat is rotatably connected with a guide wheel, and the inner cavity of the placement frame is provided with through grooves corresponding to the fixing seat one by one;

[0010] The inner cavity of the auxiliary frame is provided with a support mechanism for supporting the placement frame. When the concrete block is moved by a machine, the support rod is placed, and the surface of the guide wheel is flush with the upper end of the through groove. At this time, the concrete block is moved into the inner cavity of the placement frame by the machine, and then the lifting rod of the lifting connection component is connected to the hook for lifting. After the lifting, it automatically descends under the action of gravity and is buffered by the return spring to prevent violent impact caused by rapid falling and resulting in shaking. At this time, the support rod is removed, and after being hoisted in place and dropped, under the action of gravity, the guide wheel inside the auxiliary frame enters the through groove, pushing up the concrete block inside the placement frame. At this time, with the help of the guide wheel, the concrete block can be quickly slid and discharged through the guide plate. When manually loading the concrete block, the support rod is taken out. Under the action of gravity, the guide wheel is located above the placement frame. By pushing the concrete block to rotate through the guide wheel, the friction can be reduced, and the stacking can be quickly carried out.

[0011] As a further solution of the present invention: The buffer mechanism includes a guide block fixed to the side of the placement frame and a guide groove opened in the inner cavity of the auxiliary frame. The guide block is slidably arranged in the guide groove. The top of the inner cavity of the guide groove is fixedly connected with a return spring whose bottom end is fixedly connected to the top of the guide block. Through the arrangement of the guide groove and the guide block, when lifting, the auxiliary frame can automatically descend under the action of gravity and is buffered by the return spring to prevent violent impact caused by rapid falling and resulting in shaking.

[0012] As a further solution of the present invention: The lifting connection component includes a plurality of through cylinders fixed to the side wall of the placement frame. The through cylinder is inserted with a lifting rod on the side away from the placement frame. A nut threadedly connected to one end of the lifting rod is arranged on the side of the through cylinder close to the placement frame. The end of the lifting rod is provided with a hook section bent downward. Through the preset through cylinder, the lifting rod can be freely installed according to the lifting weight and position, the hook position can be adjusted in real time according to the lifting center of gravity, and the problem of welding failure of the welded ear after long-term use is avoided. The operation is simple and convenient to use.

[0013] As a further solution of the present invention: The support mechanism includes a support rod passing through the auxiliary frame through a support groove and a support block fixed in the inner cavity of the auxiliary frame. When the support rod is placed, the surface of the guide wheel is flush with the upper end of the through groove. When the support rod is taken out, the support block abuts against the bottom of the placement frame, and the guide wheel is located above the through groove. Through the arrangement of the support rod and the support block, there are two usage states respectively. Through the arrangement of the support rod, the support between the auxiliary frame and the placement frame is carried out, so that the guide wheel does not play a role. When the guide wheel is needed, the support rod is taken out, and the guide wheel can play an auxiliary movement role on the concrete block inside the placement frame.

[0014] As a further solution of the present invention: grid plates are inserted on both sides of the placement frame to protect the sides through the grid plates and prevent possible dropping.

[0015] As a further solution of the present invention: a guiding plate is rotatably connected to the side of the placement frame. The guiding plate gradually slopes downward along the outer surface of the placement frame and the end is flush with the lowest position of the auxiliary frame. Through the setting of the guiding plate, the up and down movement of the concrete blocks is more convenient.

[0016] As a further solution of the present invention: a plurality of lifting connection components are provided and symmetrically arranged on the side of the placement frame.

[0017] The present invention has the following beneficial effects compared with the prior art:

[0018] 1. Buffer and shock absorption: By cooperating the reset spring with the guiding groove / block, the impact energy is absorbed during lifting to prevent the frame from shaking violently.

[0019] 2. High-efficiency loading and unloading: By cooperating the guiding wheel with the through groove, the moving resistance of the blocks is reduced by using rolling friction, and rapid discharging is realized in combination with the deployable guiding plate.

[0020] 3. Adjustable hoisting design: The modular hoisting rod is flexibly installed through the through cylinder to adapt to different center-of-gravity requirements and avoid the risk of welding fatigue.

[0021] 4. Dual-mode switching: By combining the support rod with the support block, two states of "fixed support" and "guiding assistance" are realized to adapt to mechanical hoisting and manual stacking scenarios.

[0022] 5. Safety improvement: The grid plate protection and inclined guiding plate design can effectively prevent the blocks from slipping and reduce the operation risk. Description of the Drawings

When the concrete block is moved by the machine, the support rod 10 is placed, and the surface of the guide wheel 6 is flush with the upper end of the through groove 7. At this time, the concrete block is moved to the inner cavity of the placing frame 2 by the machine, and then connected with the hook through the lifting rod 4 of the lifting connection assembly for lifting.

When the support rod 10 is taken out, the support block 8 abuts against the bottom of the placement frame 2, and the guide wheel 6 is located above the through groove 7. Through the arrangement of the support rod 10 and the support block 8, there are two usage states respectively. Through the arrangement of the support rod 10, the auxiliary frame 1 and the placement frame 2 are supported, so that the guide wheel 6 does not play a role. When the guide wheel 6 needs to be used, the support rod 10 is taken out, and the guide wheel 6 can play an auxiliary movement role for the concrete blocks inside the placement frame 2.
