[0005] Two sets of slide rail assemblies are detachably connected to the bottom support. Each slide rail assembly includes a bottom plate, a standard plate, and a top plate, with the top plate contacting the roof layer. A lifting vehicle is slidably connected to the slide rail assemblies. A material frame is slidably connected to the lifting vehicle. A drive mechanism for moving the lifting vehicle includes a traction rope and a winding machine that pass through the lifting vehicle.

[0022] 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.

[0023] like Figure 1 As shown, a construction lifting device includes a ground level 1 and a roof level 2, comprising: a bottom support 3 disposed on the ground level 1; two sets of slide rail assemblies 4 detachably connected to the bottom support 3, the slide rail assembly 4 including a bottom plate 41, a standard plate 42 and a top plate 43, the top plate 43 contacting the roof level 2; a lifting vehicle 5 slidably connected to the slide rail assembly 4; a material frame 6 slidably connected to the lifting vehicle 5; and a drive mechanism 7 for driving the lifting vehicle 5 to move, the drive mechanism 7 including a traction rope 71 passing through the lifting vehicle 5 and a winding machine 72.

[0024] The bottom support 3 is equipped with a first counterweight 31, which fixes the bottom support 3 to the ground layer 1, so that the bottom support 3 can cope with the weight of the lifting material. The top of the bottom support 3 is equipped with a connecting platform 32, which is horizontal with the ground layer 1. The top of the connecting platform 32 is 50cm away from the top of the ground layer 1, so that the height of the lifting vehicle 5 at the bottom can facilitate the loading and unloading of construction personnel and avoid prolonged bending work that may damage their health.

[0025] The bottom plate 41 is rotatably connected to the bottom of the bottom plate 41. The first rotating plate 411 is in contact with the connecting platform 32. The first rotating plate 411 and the connecting platform 32 are connected by a first pin 321. The first pin 321 passes through the first rotating plate 411 and the connecting platform 32, and restricts the sliding of the first rotating plate 411.

[0026] A second rotating plate 431 is rotatably connected to the upper part of the top plate 43, and the second rotating plate 431 is in contact with the top surface of the roof layer 2. By rotating the first rotating plate 411 and the second rotating plate 431, the slide assembly 4 can adapt to the horizontal distance between the connecting platform 32 and the roof layer 2, and at the same time, the slide assembly 4 can change different tilt angles.

[0027] Mounting holes are provided on the upper part of the bottom plate 41, both ends of the standard plate 42, and the lower part of the top plate 43. A connecting plate 44 is fitted between adjacent mounting holes. A second pin 45 can be inserted into the mounting holes, and the second pin 45 passes through the connecting plate 44. The two second pins 45 connect the standard plate 42 to its adjacent slide rail assembly 4, so that the bottom plate 41, the standard plate 42, and the top plate 43 are connected as a whole. The number of standard plates 42 is determined according to the height to be raised or lowered, and is used to accommodate different raising or lowering heights.

[0028] Support rods 46 are rotatably connected to the bottom surfaces of the bottom plate 41, standard plate 42, and top plate 43. Reinforcing rods 462 are fixedly connected between adjacent support rods 46, connecting the two support rods 46 and thus connecting the two sets of slide rail assemblies 4 into a whole, making the slide rail assembly 4 more stable and enhancing its load-bearing capacity. Support legs 461 are screwed to the bottom of the support rods 46. The bottom of the support legs 461 contacts the ground layer 1. After the support rods 46 are installed, rotating the support legs 461 ensures that the bottom surface of the support legs 461 is tightly fitted to the ground layer 1, guaranteeing the support effect of the support rods 46 on the slide rail assembly 4. The rotation of the support legs 461 can adapt to the depressions and undulations of the ground layer 1.

[0029] The bottom plate 41, standard plate 42, and top plate 43 are equipped with slide rails 47. When the bottom plate 41, standard plate 42, and top plate 43 are spliced ​​together, the slide rails 47 are also connected in a straight line. The bottom of the lifting vehicle 5 is slidably connected to the slide rails 47, which restrict the left and right swaying of the lifting vehicle 5 during movement. The lifting vehicle 5 is selected with different bottom tilt angles according to the different tilt angles of the slide rail assembly 4, ensuring that the top surface of the lifting vehicle 5 is parallel to the ground floor 1 or the roof floor 2.

[0030] like Figure 2As shown, the lifting vehicle 5 is equipped with a chute 51, and the bottom of the material frame 6 is equipped with a pulley 61. The pulley 61 is slidably connected to the chute 51, and the material frame 6 can slide in and out of the lifting vehicle 5. The pulley 61 reduces friction, allowing the material frame 6 to move easily and effortlessly. The bottom of the outlet of the lifting vehicle 5 is also rotatably connected to a limit plate 52. When the material frame 6 is in the lifting vehicle 5, the limit plate 52 rotates upward so that the side wall of the limit plate 52 contacts the material frame 6. At the same time, a screw 521 passes through the limit plate 52 and is screwed to the side wall of the lifting vehicle 5. At this time, the screw 521 restricts the rotation of the limit plate 52, and the limit plate 52 restricts the material frame 6 from moving outward. When it is necessary to move the material frame 6, the screw 521 is unscrewed and the limit plate 52 is rotated downward to release the restriction of the limit plate 52 on the material frame 6.

[0031] When the lifting vehicle 5 is at the highest point of the lifting, the bottom surface of the material frame 6 is at the same height as the second rotating plate 431. The material frame 6 moves outward, causing the pulley 61 to move on the second rotating plate 431, thereby loading and unloading the material in the material frame 6 from the roof layer 2. After the loading and unloading is completed, the lifting vehicle 5 moves to the position that contacts the first rotating plate 411. At this time, the material can be transferred from the material frame 6 to the ground layer 1.

[0032] The traction rope 71 passes through the second rotating plate 431 and can slide in the second rotating plate 431. The traction rope 71 is wound around the winding machine 72, which is driven by the motor 73. The bottom of the traction rope 71 is attached to the bottom of the lifting vehicle 5 by a knot or a connected steel plate. The winding machine 72 rotates to drive the traction rope 71 to wind up and down. When the traction rope 71 is contracted, it drives the lifting vehicle 5 to move upward. When the traction rope 71 is unwinded, the lifting vehicle 5 moves under the action of gravity.

[0033] A second counterweight 21 is provided on the roof layer 2. The second counterweight 21 is connected to the second rotating plate 431 and the winding machine 72. The second counterweight 21 fixes the position of the second rotating plate 431 and the winding machine 72, so that the traction rope 71 can drive the lifting vehicle 5 to move and transfer materials.

[0034] By establishing a fixed channel through the slide assembly 4, materials within a small area of ​​the ground floor 1 can be transferred to the roof floor 2, eliminating the rental costs of using a crane for transfer and saving resources and costs.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
