DETAILED DESCRIPTION

[0024] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods, but the protection scope and application scope of the present invention are not limited.

[0025] Example 1

[0026] A material hoist with high stability for construction projects, such as Figure 1-Figure 3 , Figure 7-Figure 9As shown, it includes a storage rack 1, a fixing member 21, a moving block 24, a steel cable 12, a fixing mechanism 2 and a tightening mechanism 3. The middle parts of the left and right sides of the storage rack 1 are fixedly connected with fixing members 21, and the upper inner parts of the two fixing members 21 are slidably connected with moving blocks 24. The tops of the two moving blocks 24 are connected to the steel cables 12. The left and right sides of the upper side of the storage rack 1 are provided with fixing mechanisms 2 for fixing the moving blocks 24 and the steel cables 12, and a tightening mechanism 3 for tightening the steel cables 12 inwardly is provided between the two steel cables 12.

[0027] like Figure 1-Figure 3 As shown, the fixing mechanism 2 includes a first rotating wheel 22, a screw rod 23, a connecting frame 25, a tension spring 26 and a guide wheel 27. The screw rods 23 are rotatably connected to the inner parts of the upper sides of the two fixing members 21. The outer ends of the two screw rods 23 are fixedly connected to the first rotating wheel 22. The two screw rods 23 pass through the corresponding moving blocks 24. The screw rods 23 have a limiting effect on the moving blocks 24. The moving blocks 24 slide on the corresponding screw rods 23. The tops of the two fixing members 21 are rotatably connected to the connecting frames 25. Tension springs 26 are connected between the two connecting frames 25 and the fixing members 21. The tops of the two connecting frames 25 are connected to guide wheels 27, and the guide wheels 27 are used to guide the steel cables 12.

[0028] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the tightening mechanism 3 includes a protective cover 31, a second rotating wheel 32, a first connecting rod 33, a gear 34, a rack 35, a connecting plate 36, a pressure spring 37, a spring block 38 and a gear ring 39. The two steel cables 12 are connected with racks 35, and the two racks 35 are arranged opposite to each other. The middle part of the bottom side of the two racks 35 is slidably connected to the protective cover 31, the bottom side of the protective cover 31 is rotatably connected to the first connecting rod 33, and the bottom end of the first connecting rod 33 is fixedly connected to the second rotating wheel 3 2. A gear 34 is connected to the top of the first connecting rod 33. The gear 34 is between the two racks 35. The gear 34 and the two racks 35 are meshed with each other. A plurality of toothed rings 39 are connected to the middle circumferential direction of the bottom of the protective cover 31. A connecting plate 36 is fixedly connected to the middle of the first connecting rod 33. A spring block 38 is slidably connected to the upper outer side of the connecting plate 36. The plurality of toothed rings 39 have a blocking effect on the spring block 38. A pressure spring 37 is connected between the connecting plate 36 and the spring block 38.

[0029] like Figure 1 , Figure 4-Figure 6 As shown, the surface material of the second rotating wheel 32 is rubber, which plays an anti-slip role.

[0030] When construction materials need to be transported at a construction site, the material hoist with high stability for construction engineering can be used to transport construction materials. People first place the construction materials on the storage rack 1, and then rotate the first rotating wheel 22 on the left. The rotation of the first rotating wheel 22 drives the screw 23 to rotate, so that the moving block 24 moves inward on the screw 23, so that the moving block 24 on the left is in close contact with the fixing member 21, and then the first rotating wheel 22 on the right is rotated, which will make the moving block 24 on the right and the fixing member 21 in close contact, so that the steel cables 12 on the left and right sides are close to the inner side of the fixing member 21, so as to avoid the shaking of the steel cables 12 during transportation, and then rotate the second rotating wheel 32 counterclockwise. Since the surface of the second rotating wheel 32 is made of rubber material, it can prevent the hand from slipping. The rotation of the second rotating wheel 32 drives the first connecting rod 33 to rotate counterclockwise, and the first connecting rod 33 rotates counterclockwise. The rotation of the rod 33 drives the gear 34 to rotate counterclockwise, so that the two racks 35 move inward, thereby tightening the two steel cables 12 inward, further fixing the steel cables 12, and effectively preventing the steel cables 12 from shaking during transportation, thereby driving the storage rack 1 to shake. The first connecting rod 33 rotates counterclockwise to drive the connecting plate 36 to rotate, thereby driving the elastic block 38 to rotate counterclockwise on the gear ring 39. The gear ring 39 can block the elastic block 38 to prevent the elastic block 38 from rotating clockwise, preventing the first connecting rod 33 from rotating clockwise, and preventing the tightened steel cable 12 from loosening. After the adjustment is completed, the steel cable 12 is retracted upward, and the steel cable 12 moves upward, which can drive the storage rack 1 to move upward, thereby realizing the transportation of building materials from a low place to a high place, and effectively preventing it from shaking during transportation, with higher stability and lower risk factor.

[0031] Example 2

[0032] On the basis of Example 1, Figure 1 , Figure 7 and Figure 8 As shown, a protective mechanism 4 for preventing building materials from falling is also included, and the protective mechanism 4 includes a protective cloth 41, a second connecting rod 42, a fixing plate 43, a torsion spring 44, a pull ring 45 and a hook 46. The second connecting rods 42 are rotatably connected between the front and rear sides of the left and right parts of the storage rack 1 and the fixing member 21. The number of the second connecting rods 42 is four, and each second connecting rod 42 is connected to a protective cloth 41. The protective cloth 41 is used to prevent building materials from falling. The bottom sides of the four protective cloths 41 are fixedly connected to the pull ring 45, the outer sides of the four second connecting rods 42 are connected to the fixing plates 43, and the torsion springs 44 are connected between the fixing plates 43 and the corresponding second connecting rods 42. The left and right ends of the bottom side of the storage rack 1 are symmetrically connected to the hooks 46, and the hooks 46 are used to fix the pull rings 45.

[0033] After the building materials are placed, the pull ring 45 is pulled downward by hand, driving the protective cloth 41 to move downward and open. The protective cloth 41 moves downward and opens, driving the second connecting rod 42 to rotate, and the torsion spring 44 is twisted. The pull ring 45 is pulled downward to the lowest part and then hung on the hook 46, thereby fixing the pull ring 45, so that the protective cloth 41 can be unfolded downward to cover the building materials placed on the storage rack 1, and prevent the building materials from falling during transportation. When the use is finished, the pull is removed from the hook 46, and the torsion spring 44 restores its elastic deformation, driving the second connecting rod 42 to rotate, so that the protective cloth 41 moves upward and rolls up.

[0034] like Figure 1 , Fig. 9 and Fig.10 As shown, a buffer mechanism 5 is also included for buffering the falling of the storage rack 1. The buffer mechanism 5 includes a buffer plate 51, a buffer spring 52 and a guide rod 53. The four top corners of the storage rack 1 are slidably connected to the guide rod 53. The buffer plate 51 is fixedly connected between the bottom ends of the four guide rods 53. Four buffer springs 52 are connected between the storage rack 1 and the buffer plate 51. The buffer springs 52 are all sleeved on the guide rod 53, and the guide rod 53 guides the buffer springs 52.

[0035] When the material hoist with high stability for construction engineering moves downward to the ground after use, the buffer plate 51 contacts the ground first, and the buffer spring 52 can buffer the rack 1 to prevent the rack 1 from colliding with the ground due to excessive falling speed, thereby damaging the rack 1.

Personnel familiar with the art can make various modifications or changes to the above embodiments without departing from the utility model concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope of the innovative features mentioned in the claims.
