Description
Technical Field
[0001] This application relates to the field of hoisting equipment, and in particular to a building material hoisting device. Background Art
[0002] During the construction process, a large amount of building materials such as bagged concrete, building blocks, and bricks are required. The above building materials are neatly stacked in a designated storage area during the construction process, such as Figure 1 , and a pallet 11 is provided at the bottom of the building material 1 to support the building material 1 off the ground, preventing the building material 1 from getting wet and facilitating the movement of the building material 1.
[0003] When using building materials, they need to be hoisted by a crane. Currently, usually, after the building materials stacked on the pallet are tied and fixed to the pallet by a cable, the pallet is then connected to the lifting tool of the crane, and then the crane is used to hoist the pallet together with the building materials on the pallet.
[0004] In view of the above related technologies, the operation method of tying and limiting the building materials to the pallet by a cable before hoisting the building materials is not only cumbersome, but also once the cable becomes loose during the subsequent hoisting process, it will directly cause the building materials to fall off the pallet, extremely likely to cause safety accidents; therefore, there is room for improvement. Utility Model Content
[0005] In order to improve the stability of building materials during hoisting, this application provides a building material hoisting device.
[0006] A building material hoisting device provided by this application adopts the following technical solutions:

Corresponding to the support rods, main ear plates are provided on opposite sides of the bottom of the hanging frame. Both ends of the support rods are respectively inserted through the corresponding main ear plates on opposite sides of the bottom of the hanging frame; both ends of the support rods are detachably connected with limiting members, and the limiting members at both ends of the support rods cooperate to limit the support rods from disengaging from the main ear plates; a plurality of hanging rings are connected to the top of the hanging frame.
[0008] By adopting the above technical solution, when hoisting building materials, after the hanging frame is sleeved on the building materials to be hoisted, the support rod is inserted into the gap between the pallet and the ground and the corresponding main ear plates on the opposite sides of the bottom of the hanging frame. Then, limit pieces are installed at both ends of the support rod to limit the sliding of the support rod. Next, the hanging ring is connected to the lifting appliance of the crane through a cable, and the crane lifts the hanging frame together with the building materials in the hanging frame. During the hoisting process of the crane, the bottom support structure formed by several support pipes at the bottom of the hanging frame firmly supports the building materials.

[0011] Preferably, several limit ropes are further arranged at the top of the hanging frame, and both ends of the limit ropes are respectively connected to the opposite sides of the hanging frame.
[0012] By adopting the above technical solution, through the arrangement of several limit ropes, the top of the hanging frame is assisted in being limited by the several limit ropes, which is beneficial to reducing the situation that the building materials at the top end of the hanging frame slide outwards from the top of the hanging frame during subsequent hoisting; at the same time, when a rainproof cloth is supported on the top of the building materials subsequently, the rainproof cloth is pressed on the top of the building materials through the several limit ropes.
[0013] Preferably, several storage pipes are arranged at the top of the hanging frame corresponding to the several support rods, and the storage pipes are used for the corresponding support rods to pass through.
[0014] By adopting the above technical solution, when the hanging frame is stored or transported, the support rod can be inserted into the storage pipe at the top end of the hanging frame, realizing the storage of the support rod and facilitating the immediate extraction and use of the support rod when the hanging frame is used subsequently.
[0015] Preferably, fastening bolts are threadedly connected to the outer periphery of the storage pipe, and the bottom ends of the fastening bolts extend into the inner cavity of the storage pipe.
[0016] By adopting the above technical solution, after passing the support rod through the storage tube, by screwing the fastening bolt on the storage tube, the fastening bolt is tightened against the support rod to realize the limitation of the support rod, reducing the situation that the support tube in the storage tube slides during the subsequent movement of the hanging frame.
[0017] Preferably, a grid plate is disposed around the outer periphery of the hanging frame, and the grid plate is fixedly welded to the outer side of the hanging frame.

[0034] The following further describes the present application in detail Figure 2 - 5 in conjunction with the attached drawings.
[0035] An embodiment of the present application discloses a lifting device for building materials 1. Referring to Figure 2 and Figure 3 , it includes a hanging frame 2. A plurality of lifting rings 24 are welded and fixed at the top of the hanging frame 2. A bottom support assembly is provided at the bottom of the hanging frame 2. The bottom support assembly includes support rods 21 arranged in parallel. Main ear plates 22 are welded to the opposite sides of the bottom of the hanging frame 2 corresponding to the support rods 21. The support rods 21 pass through the main ear plates 22 opposite to each other at the bottom of the hanging frame 2. Limit members are detachably installed at both ends of the support rods 21. The limit members at both ends of the support rods 21 cooperate to prevent the support rods 21 from detaching from the two corresponding main ear plates 22.
[0036] When lifting building materials 1, the hanging frame 2 is sleeved around the outer periphery of the building materials 1, so that the support rods 21 penetrate into the gap between the pallet 11 and the ground, and both ends of the support rods 21 are respectively inserted into the corresponding two main ear plates 22. Limiters are installed at both ends of the support rods 21; a base for supporting the building materials 1 is formed by a number of support rods 21. After the bottom lifting ring 24 of the hanging frame 2 is connected to the crane lifting tool through a cable, the hanging frame 2 together with the building materials 1 is lifted by the crane. During the lifting process of the building materials 1, the building materials 1 are enclosed and limited by the hanging frame 2, effectively preventing the building materials 1 on the pallet 11 from falling.
[0037] In this embodiment, the hanging frame 2 is fixedly welded by a number of square tubes. In other embodiments, the square tubes can also be replaced by steel bars or metal pipes, etc. Grid plates 23 are fixedly welded on the outer sides of the hanging frame 2. Through the arrangement of the grid plates 23, on the one hand, it is convenient to block the gaps of the hanging frame 2 through the grid plates 23, reducing the situation that building materials 1 with a smaller volume such as bricks are likely to fall through the gaps of the hanging frame 2 during lifting. On the other hand, it is beneficial to further improve the overall strength and connection integrity of the hanging frame 2. The hanging frame 2 and the grid plates 23 are both painted with anti-rust paint, so that the hanging frame 2 and the grid plates 23 are not easily rusted during daily use.
[0038] Universal wheels 26 are installed at the four top corners of the bottom of the hanging frame 2. The bottoms of the main ear plates 22 are all higher than the bottoms of the universal wheels 26. When the hanging frame 2 is stored or transported, it can slide on the ground through the four universal wheels 26 at the bottom, facilitating the storage and transportation of the hanging frame 2. A number of guy ropes (not shown in the figure) are tied and connected to the bottom of the hanging frame 2. The setting of the guy ropes enables ground construction personnel to assist in towing the hanging frame 2 through the guy ropes when the crane lowers the hanging frame 2 and the building materials 1 in the hanging frame 2 later, facilitating the stable lowering and positioning of the hanging frame 2.
[0039] A number of limit ropes (not shown in the figure) are also provided at the top of the hanging frame 2. A number of secondary ear plates 25 are welded to the top of the hanging frame 2 corresponding to the limit ropes on the opposite sides; the limit ropes are respectively buckled to the corresponding secondary ear plates 25 on both sides of the top of the hanging frame 2 through spring buckles, realizing the stable connection of both ends of the limit ropes to the opposite sides of the top of the hanging frame 2. The setting of the limit ropes can limit the top of the hanging frame 2, preventing the building materials 1 from slipping from the top of the hanging frame 2 during the subsequent lifting process.
[0040] The limiters at both ends of the support rod 21 are respectively located on the opposite sides of the two main ear plates 22 at the bottom of the hanging frame 2. The limiter includes a limit bolt 211 and a limit nut 212. A through hole for the limit bolt 211 to pass through is provided on the outer periphery of the support rod 21 corresponding to the limit nut 212; the limit bolt 211 passes through the support rod 21 through the through hole, and the limit nut 212 is threadedly connected to the tail end of the limit bolt 211 and abuts against the support rod 21, realizing the detachable installation of the limiter on the support rod 21.
[0041] Referring to Figure 2 and Figure 4 , several storage tubes 3 are fixedly welded to the top of the hanging frame 2 corresponding to several support rods 21; the storage tubes 3 are horizontally arranged; the storage tubes 3 are used for the corresponding support rods 21 to pass through, and fastening bolts 31 are threadedly connected to the outer periphery of each storage tube 3, and one end of each fastening bolt 31 extends into the inner cavity of the storage tube 3; when the hanging frame 2 is subsequently transported or stored, the support rods 21 can be inserted into the corresponding storage tubes 3, and the fastening bolts 31 on the storage tubes 3 are screwed until the fastening bolts 31 abut against the outer periphery of the support rods 21, so as to realize the storage and fixation of the support rods 21. When hoisting the building materials 1 by a hoisting device, it is convenient to timely take out the support rods 21 from the hanging frame 2 for use.
[0042] The implementation principle of the embodiment of the present application is that when hoisting the building materials 1 by a hoisting device, referring to Figures 2 to 5 , it includes the following steps:
[0043] S1: Positioning the hanging frame 2: Put the hanging frame 2 on the building materials 1 to be hoisted;
[0044] S2: Assembling the bottom support structure: While inserting the support rods 21 into the gap between the bottom plate 11 of the building materials 1 and the ground, the two ends of the support rods 21 are respectively inserted into the corresponding main ear plates 22 on the opposite sides of the bottom of the hanging frame 2;
[0045] S3: Installing the limiting parts: Insert the limiting bolts 211 through the through holes into the support rods 21, screw the limiting nuts 212 onto the tail ends of the support rods 21 and make them abut against the outer periphery of the support rods 21, and use the limiting parts at both ends of the support rods 21 to cooperate to prevent the two ends of the support rods 21 from detaching from the main ear plates 22;
[0046] S4: Connecting the lifting appliance: Connect the lifting rings 24 at the top of the hanging frame 2 to the lifting appliance of the crane through cables;
[0047] S5: Lifting the building materials 1: Lift the hanging frame 2 together with the building materials 1 in the hanging frame 2 off the ground by the crane.
[0048] When hoisting the building materials 1 by the hoisting device, the building materials 1 on the bottom plate 11 can be surrounded and limited by the hanging frame 2, so as to prevent the building materials 1 from falling during the hoisting process by the crane, which is beneficial to improving the hoisting stability of the building materials 1.
[0049] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
