Description

Technical Field

[0001] The utility model relates to the technical field of material conveying equipment, in particular to a vertical lifting load hoist. Background Art

[0002] In construction projects, buildings are often not low-rise buildings with only one floor. One of the engineering problems brought about by the increase in building height is the transportation of materials. The higher the building height, the more difficult and complicated the material transportation is, and it is usually impossible to complete it by manpower. Since ancient times, people have begun to use fixed pulley systems to lift and transport materials in construction projects to assist the project. In modern construction projects, lifting and transporting materials by equipment has become a very common material transportation method. Construction site material hoists have also been widely used and are one of the indispensable construction equipment.

[0003] Most of the existing cargo elevators currently have only a single machine column frame as the lifting track of the lifting box, and lack further reinforcement and protection measures. In particular, the elevators with two lifting boxes basically rely on one machine column frame as the track limit, and the structural stability is insufficient. In addition, the lifting box only has the function of loading materials, and cannot provide assistance for the loading and unloading of materials, and its functionality is insufficient.

[0004] In order to solve the above problems, we have made improvements and proposed a vertical lifting cargo elevator. Utility Model Content

There are two lifting boxes 6, which are respectively located on both sides of the column frame 2, and between the two protective columns 5, two groups of limit plates 7 are fixedly welded on the side of the lifting box 6 close to the column frame 2, and two limit frames 8 are fixedly welded on the side of the lifting box 6 close to the protective column 5. A slide rail plate 9 is hinged on the bottom of the front of the lifting box 6. The two lifting boxes 6 are completely symmetrical with the winch unit 3 as the center.

[0021] Fixed pulley groups are fixedly provided on the left and right ends of the top surface of the top frame 4, and lifting rings are fixedly welded on the left and right ends of the bottom surface of the top frame 4. A movable pulley is fixedly provided on the top surface of the lifting box 6. The two winches in the winch group 3 are respectively wound with cables. The two cables are respectively passed through the two groups of fixed pulleys of the top frame 4 and the movable pulleys of the two lifting boxes 6 in turn, and are finally fixedly connected with the lifting rings.

[0022] The slide plate 9 is composed of a hollow frame and a plurality of rotating rollers, which are rotatably connected to the inside of the hollow frame at equal intervals. A handle 10 is fixedly welded to the middle of the top surface of the slide plate 9. The height of the slide plate 9 is close to two-thirds of the height of the lifting box 6, and the width is slightly smaller than the width of the lifting box 6.

[0023] A connecting block is fixedly welded on the right end of the front of the lifting box 6, and a baffle 11 is rotatably set on the front of the connecting block. A hook 12 is fixedly welded on the left end of the front of the right lifting box 6. The number of hooks 12 is equal to the number of connecting blocks and the height positions are equal. The left end of the baffle 11 is connected to the hook 12.

[0024] The limit plate 7 is composed of two square plates, which are respectively located on the front and back sides of the machine column frame 2. A secondary limit plate 13 is vertically fixed and welded to the middle of the inner wall of the limit plate 7. The secondary limit plate 13 and the side of the limit plate 7 close to the machine column frame 2 are both fixed with a first roller 14 by bolts, and the first roller 14 is connected to the machine column frame 2.

[0025] The protective column 5 passes through the interior of the limiting frame 8, and a wheel seat 15 is fixedly welded inside the limiting frame 8. The side of the wheel seat 15 away from the protective column 5 is fixedly welded to the lifting box 6.

A wheel groove is opened on the side of the protective column 5 close to the lifting box 6, and the second roller 16 is connected to the wheel groove of the protective column 5.

[0026] Working principle: This type of vertical lifting cargo hoist controls the lifting of the lifting box 6 through the winch unit 3 in conjunction with the fixed pulley and movable pulley system. When it is on the base 1, rotate the baffle 11 to make it leave the hook 12 until it rotates to the other side, then grasp the handle 10 to rotate the slide plate 9 to the ground and lower it, and then the material can be loaded into the lifting box 6 with the assistance of the rotating roller of the slide plate 9. After loading is completed, rotate the baffle 11 in the opposite direction until it is fixed on the hook 12. After controlling the winch unit 3 to lift the lifting box 6 to the specified floor height, repeat the operation to lower the slide plate 9 to assist in unloading the material. During the lifting and lowering process of the lifting box 6, the limit frame 8 and the limit plate 7 limit its position, and the internal first roller 14 and second roller 16 assist in lifting and reducing friction.
