DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1 and Figure 2 As shown, a building material lifting rack includes a movable base 1 and a material receiving box 29, a lifting component 2 is fixedly installed on the upper end of the base 1, a limited position anti-falling component 3 is fixedly installed on the front and rear sides of the lifting component 2, and a unloading component 4 is fixedly installed on the front left side of the lifting component 2.

[0027] The lifting assembly 2 can lift the building materials to different directions according to the actual situation. The position-limiting anti-falling assembly 3 can not only limit the moving direction of the material receiving box 29, so that the material receiving box 29 always moves vertically up and down, but also the cooperation of the ratchet 36 and the pawl 37 can clamp the material receiving box 29 when an accident occurs to the steel rope 27, so as to prevent the material receiving box 29 from falling from a high place. The unloading assembly 4 can quickly take out the materials in the material receiving box 29 when the unloading plate 45 is opened when the material is lifted to the designated position, thereby improving the practicality of the lifting frame.

[0028] like Figure 2 As shown, the lifting assembly 2 includes a motor 21, a mounting frame is fixedly installed on the upper end of the motor 21, and the lower end of the mounting frame is fixedly installed on the rear part of the upper end of the base 1. A driving gear 22 is fixedly sleeved on the output end of the motor 21, and a rotating shaft 23 is rotatably connected to the middle part of the upper end of the base 1. A driven gear 24 is fixedly sleeved on the bottom of the outer wall of the rotating shaft 23, and the outer surface of the driving gear 22 is meshed with the outer surface of the driven gear 24.

[0029] The driving gear 22 is driven to rotate by the output end of the motor 21 , and the driven gear 24 is meshed with the driving gear 22 to drive the rotating shaft 23 to rotate by a certain angle.

[0030] like Figure 2As shown, a mounting plate 25 is fixedly installed on the upper end of the rotating shaft 23, a winding mechanism 26 is fixedly installed on the upper rear part of the mounting plate 25, a steel rope 27 is wound around the outer wall of the winding mechanism 26, and the upper front part of the mounting plate 25 is rotatably connected to a limiting wheel 28, the outer wall of the steel rope 27 overlaps the outer surface of the limiting wheel 28, and the end of the steel rope 27 away from the winding mechanism 26 passes through the top of the mounting plate 25 and is fixedly installed with a material receiving box 29.

[0031] The winding mechanism 26 is composed of a driving motor and a rotating shaft. The output end of the driving motor drives the rotating shaft to rotate. The steel rope 27 is wound around the outer wall of the rotating shaft. The steel rope 27 is wound around the outer wall of the rotating shaft to release or reel in the wire through the rotation of the rotating shaft, thereby realizing the lowering and lifting of the receiving box 29. The limiting wheel 28 has a limiting effect on the reeling and unreeling of the steel rope 27.

[0032] like Figure 3 and Figure 4 As shown, the limit anti-falling component 3 includes a slide rail 31, the upper end of the slide rail 31 is fixedly installed at the left position of the front lower end of the mounting plate 25, a slide plate 32 is fixedly installed at the left rear side of the material receiving box 29, the rear side of the slide plate 32 is slidably connected to the inner wall of the slide rail 31, and fixed blocks 33 are fixedly installed at the left and right positions of the rear right side of the material receiving box 29, and the opposite sides of the two fixed blocks 33 are rotatably connected with gears 1 34, and a rack 1 35 is fixedly installed at the right position of the front lower end of the mounting plate 25, and the outer surface of the gear 1 34 is meshed with the front side of the rack 1 35.

[0033] When the material receiving box 29 moves, the cooperation between the slide plate 32 and the slide rail 31 can limit the movement of the material receiving box 29, making the material receiving box 29 move more smoothly when moving up and down. The cooperation between the gear 1 34 and the rack 1 35 makes it more stable when the material receiving box 29 is stuck.

[0034] like Figure 4 As shown, the right part of the outer wall of the gear shaft of gear 1 34 passes through the right part of the right fixed block 33 and is fixedly sleeved with a ratchet 36, and the right front part of the right fixed block 33 is rotatably connected with a pawl 37, the rear end of the pawl 37 is meshed with the outer surface of the ratchet 36, and a return spring 38 is fixedly installed on the front side of the pawl 37, and the end of the return spring 38 away from the pawl 37 is fixedly connected to the right front part of the right fixed block 33.

[0035] When the ratchet 36 is driven to rotate by the gear 1 34, it pushes the pawl 37 to rotate and compresses the reset spring 38. The elastic restoring force of the reset spring 38 can drive the pawl 37 to reset and re-engage with the ratchet 36, so that the ratchet 36 can only rotate in one direction, thereby increasing the safety of lifting the material receiving box 29.

[0036] like Figure 5As shown, a slide groove is opened on the right rear side of the material receiving box 29, and a slider 39 is slidably connected to the inner wall of the slide groove. A blocking rod 311 is fixedly installed on the rear side of the slider 39, and a spring 310 is fixedly installed on the left side of the slider 39. The left end of the spring 310 is fixedly connected to the left inner wall of the slide groove. A turning handle is fixedly installed at the axial position of the rotation of the pawl 37, and the outer wall of the blocking rod 311 overlaps the outer wall of the top of the turning handle.

[0037] When the material receiving box 29 moves downward, the pawl 37 will hinder the rotation of the ratchet 36. The blocking rod 311 drives the slider 39 to move in the slide groove and stretch the spring 310. The turning handle drives the pawl 37 to rotate to a position away from the ratchet 36. The blocking rod 311 is released, and the elastic restoring force of the spring 310 drives the blocking rod 311 to reset and jam the turning handle to prevent the descending work of the material receiving box 29 from being affected.

[0038] like Figure 6 As shown, the unloading assembly 4 includes an adjusting screw 41, the front and rear parts of the outer wall of the adjusting screw 41 are rotatably connected to the left front part of the material receiving box 29, the outer wall of the adjusting screw 41 is threadedly connected with a moving block 42, the lower end of the moving block 42 is fixedly installed with a rack 243, and the rack 243 is slidably connected to the left front part of the material receiving box 29.

[0039] By rotating the adjusting screw 41 , the moving block 42 is threadedly connected with the adjusting screw 41 to drive the second rack 43 to move.

[0040] like Figure 6 As shown, the front position of the bottom of the inner wall of the material receiving box 29 is rotatably connected to a connecting shaft 44 that passes through the left part of the material receiving box 29, a discharge plate 45 is fixedly installed on the middle part of the outer wall of the connecting shaft 44, and a gear 2 46 is fixedly sleeved on the left part of the outer wall of the connecting shaft 44, and the outer surface of the gear 2 46 is meshed with the lower end of the rack 2 43.

[0041] Through the movement of rack 2 43, gear 2 46 drives the connecting shaft 44 and the unloading plate 45 to rotate by meshing with rack 2 43. When unloading the material receiving box 29, the unloading plate 45 can be quickly opened. When the material receiving box 29 is lifted, the unloading plate 45 can effectively prevent the material in the box from falling.

[0042] The working principle of the utility model is as follows: the staff puts the building materials into the receiving box 29, rotates the adjusting screw 41, so that the moving block 42 drives the rack 2 43 to move, and the gear 2 46 drives the connecting shaft 44 and the discharge plate 45 to rotate through the meshing of the rack 2 43, so that the discharge plate 45 rotates until the receiving box 29 is sealed.

[0043] The motor 21 is started according to the actual lifting direction required, and the output end of the motor 21 drives the driving gear 22 to rotate, so that the driven gear 24 drives the rotating shaft 23 to rotate, and the rotating shaft 23 drives the mounting plate 25 and the material receiving box 29 to rotate to the specified position. The winding mechanism 26 is started, and the winding mechanism 26 begins to reel in the wire, and the steel rope 27 drives the material receiving box 29 to move upward, so that the material receiving box 29 slides vertically upward in the slide rail 31 through the slide plate 32, and the gear 1 34 rotates in front of the rack 1 35 by meshing with the rack 1 35. When the material receiving box is lifted to the specified position, the adjusting screw 41 is rotated in the opposite direction to rotate the unloading plate 45 to open the material receiving box 29, and the staff quickly transfers the construction materials.

[0044] When an accident occurs, the material receiving box 29 falls downward due to gravity, and the cooperation between the pawl 37 and the ratchet wheel 36 can lock the gear 1 34, thereby locking the material receiving box 29.

[0045] When the material receiving box 29 needs to be lowered, the blocking rod 311 is pulled so that the blocking rod 311 drives the slider 39 to slide in the slide groove and stretch the spring 310, and the turning handle is turned so that the turning handle drives the pawl 37 away from the ratchet 36 and the turning handle is located at the bottom of the outer wall of the blocking rod 311. The blocking rod 311 is released, and the elastic potential energy of the spring 310 drives the slider 39 and the blocking rod 311 to reset and jam the turning handle, so that the pawl 37 will not affect the rotation of the ratchet 36 when the material receiving box 29 is descending.

[0046] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
