[0001] This utility model relates to the field of material hoisting technology, specifically to a material hoisting machine that can be positioned and rotated. Background Technology

[0002] A material hoist is a mechanical device used for vertical transportation of building materials. It is widely used in construction. The material hoist uses an electric motor to drive a winch and uses steel wire ropes to lift the goods to a designated height. Its working principle is similar to that of an elevator, but it usually does not have a passenger carrying function.

[0003] In order to increase the stability of material transportation, the loading platform of the existing material hoist is usually fixed on the material hoist and can only move up and down with the material hoist. Therefore, it does not have the function of flipping the loading platform for unloading, which makes the unloading process very cumbersome and inconvenient for users. Utility Model Content

[0004] The purpose of this invention is to provide a material hoist that can be positioned and flipped to solve the problem mentioned in the background art that the currently used material hoists do not have the function of flipping and unloading the loading platform.

Detailed Implementation

[0023] 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.

[0024] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a material hoist that can be positioned and flipped, comprising: a base 1 and a lifting platform 4, a bracket 2 is installed on the top of the base 1, a drive mechanism 3 is installed in the middle of the bracket 2, and the lifting platform 4 is installed in the middle of the drive mechanism 3.

[0025] exist Figure 3 In the middle, the lifting platform 4 is connected to the loading platform 5 through a rotating shaft. The bottom of the loading platform 5 is connected to the first connecting rod 6 through a rotating shaft. One side of the first connecting rod 6 is connected to the second connecting rod 7 through a rotating shaft. One end of the second connecting rod 7 is connected to the rotating shaft 8.

[0026] This positionable and tiltable material hoist drives the second connecting rod 7 to rotate via the rotating shaft 8. When the second connecting rod 7 rotates, it drives the first connecting rod 6 to rotate via the rotating shaft. At the same time, the rotation of the first connecting rod 6 pushes the loading platform 5 to rotate via the rotating shaft between it and the lifting platform 4, thus achieving the tilting function.

[0027] exist Figure 3 In the middle, both ends of the rotating shaft 8 are equipped with support blocks 9 via bearings, and the support blocks 9 are installed on the top of the lifting platform 4.

[0028] The positioning and tilting material hoist can increase the stability of the entire rotating shaft 8 by means of the support blocks 9 at both ends of the rotating shaft 8.

[0029] exist Figure 3 In the middle, a worm gear 10 is installed on the outer side of the rotating shaft 8, and a worm 11 is installed at the bottom of the worm gear 10. The worm 11 passes through one end of the lifting platform 4 and is connected to a servo motor 12 through a coupling.

[0030] The positioning and tilting material hoist drives the worm gear 11 to rotate via the servo motor 12. The worm gear 11 is connected to the worm wheel 10, and the worm wheel 10 is installed on the outside of the rotating shaft 8. Therefore, when the worm gear 11 rotates, it will drive the rotating shaft 8 to rotate via the worm wheel 10. At this time, in conjunction with the first connecting rod 6 and the second connecting rod 7, the loading platform 5 can be tilted, which makes it convenient for the user to unload materials.

[0031] exist Figure 4 In the middle, guide blocks 13 and fixing blocks 14 are installed on the outer side of the loading platform 5, and a railing 15 is connected through the middle of the guide block 13.

[0032] This positionable and tiltable material hoist allows the railing 15 to extend and retract along the guide block 13, thereby increasing the stability of the railing 15 when it moves up and down.

[0033] exist Figure 5 and Figure 6 In the middle, the two sets of railings 15 are provided with slots on the side that are close to each other. The slots are equipped with toothed blocks 16. The top of the fixed block 14 is connected to the top rod 17. The fixed block 14 is provided with a groove. The top rod 17 and the groove are equipped with movable blocks 18. A triangular block 19 is installed on one side of the movable block 18.

[0034] The positioning and flipping material elevator, by squeezing the top rod 17 on the top of the fixed block 14, causes the top rod 17 to move into the interior of the fixed block 14. When the top rod 17 moves, it drives the movable block 18 to move, and at the same time, the movable block 18 drives the triangular block 19 to move.

[0035] exist Figure 6 In the middle, a telescopic block 20 is provided on the inclined surface of one side of the triangular block 19, which passes through the groove of the fixed block 14. A movable spring 21 is installed between the two sets of telescopic blocks 20. A through groove is opened on the side of the two sets of guide blocks 13 that are close to each other. The telescopic block 20 passes through the through groove and is connected to the groove of the railing 15.

[0036] When the triangular block 19 moves downward, the tilting material hoist will squeeze the two sets of telescopic blocks 20 through the inclined surface, causing the two sets of telescopic blocks 20 to retract into the fixed block 14 and squeeze the movable spring 21 in the middle. At this time, the telescopic blocks 20 will not pass through the through groove of the guide block 13 and connect with the two sets of toothed blocks 16 in the groove of the railing 15, and then the railing 15 can slide up and down along the guide block 13.

[0037] When the top rod 17 is released, the telescopic block 20 is no longer squeezed by the movable block 18 and the triangular block 19. Then the movable spring 21 will return to its original position and drive the telescopic block 20 to engage with the two sets of toothed blocks 16 in the groove of the railing 15. At this time, the position of the railing 15 can be fixed. By adjusting the height of the railing 15, the goods inside the loading platform 5 can be prevented from falling.

[0038] In summary: When using this positionable and tiltable material hoist, the baffle on one side of the lifting platform 4 can be rotated open, and the material to be transported can be placed in the loading platform 5. Then, the baffle is rotated in the opposite direction and fixed by a pin. At this time, the drive mechanism 3 can be started. The drive mechanism 3 mainly consists of a lead screw, a motor, a screw sleeve, and a guide rod. The motor drives the lead screw to rotate, and then the lead screw drives the screw sleeve to slide. The screw sleeve is installed on one side of the lifting platform 4, and the other side of the lifting platform 4 is slidably connected to the inside of the bracket 2 through the guide rod. Therefore, when the lead screw rotates, it drives the lifting platform 4 to move up and down, thereby lifting and transporting the material. This is the characteristic of the use of the positionable and tiltable material hoist. The contents not described in detail in this description belong to the prior art known to those skilled in the art.

[0039] Although the present invention 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 the present invention should be included within the protection scope of the present invention.
