Description

Technical Field

[0001] The utility model relates to a plastering bucket lifting mechanism and belongs to the technical field of building construction. Background Art

[0002] Ash bucket, also known as plaster bucket, is usually made of plastic and is a common container tool at construction sites or decoration sites. The main function of the ash bucket is to facilitate workers to transport the mixed mortar or mortar to the construction site for plastering work on surfaces such as walls and floors. It is usually equipped with a handle to facilitate workers to carry it.

[0003] When performing wall plastering construction, it is usually necessary to set up a scaffolding, and then the construction master climbs up the scaffolding to plaster the wall. At the same time, the workers cooperating with the construction master hand the ash bucket filled with mortar or mortar to the construction master, and then continue the plastering work.

[0004] Since the ash bucket filled with mortar or mortar is heavy, workers need to use a lot of force to lift it up and hand it to the construction master, which leads to high labor intensity. Workers who work for a long time will almost always suffer from certain strain diseases, which has a great impact on their health. The current solution is to hang the ash bucket to a certain height through a hook, but it is not only time-consuming and laborious to install the hoisting device, but also difficult to move the hoisting device, and it cannot be quickly adjusted according to the construction location, and the actual use effect is not good.

[0005] A hook-and-carry device for vertically lifting a wall plaster bucket disclosed in a Chinese utility model patent with publication number CN216512359U comprises a plate body, a plurality of hook holes are provided on the surface of the plate body along its length direction, hooks pointing vertically downward are respectively connected to the hook holes, symmetrical lugs are respectively provided on both sides of the upper end surface of the plate body, the lugs are respectively provided with lug holes, and a steel wire rope, the front section and the rear section of the steel wire rope respectively pass through the lug holes and are connected to the rope body as a whole.

[0006] The above reference examples require the additional installation of tower cranes or other lifting devices, which is time-consuming, labor-intensive and inefficient. In addition, the lifting is performed by wire ropes, which has poor stability, is prone to shaking and has poor safety, and therefore is in urgent need of improvement. Utility Model Content

DETAILED DESCRIPTION

[0027] The present invention will be described in more detail below in conjunction with the embodiments.

[0028] Embodiment 1

[0029] See also Figure 1 and Figure 2 The plaster bucket lifting mechanism of this embodiment includes a hook 7, a base 1 and a lifting mechanism. The lifting mechanism includes a connecting column 11 vertically fixed to the top of the base 1 and a fixed column 10 fixedly installed on the top of the connecting column 11. The connecting column 11 is externally rotatably sleeved with a threaded rotating rod 15, and the threaded rotating rod 15 is externally threadedly sleeved with a screw column 3. Two sets of lifting units are installed on the side of the screw column 3. The lifting unit is movably connected to the fixed column 10 and fixedly connected to the hook 7. A driving mechanism for driving the screw column 3 to rotate is arranged inside the base 1.

[0030] Specifically, in this embodiment, two groups of lifting units are symmetrically arranged on both sides of the screw-connecting column 3, so that the force on the screw-connecting column 3 is more balanced.

[0031] The trolley assembly 10 is convenient to operate and can be used for lifting and lowering the trolleys 10, so that the trolleys 10 can be easily lifted and lowered, thereby greatly improving the working efficiency.

[0032] Furthermore, the lifting unit includes an articulated seat 4, a push rod 5, a lifting rod 6 and an articulated plate 9. The articulated seat 4 is fixed on the screw column 3. One end of the push rod 5 is hinged to the articulated seat 4, and the other end is hinged to the middle part of the lifting rod 6. One end of the lifting rod 6 is hinged to the articulated plate 9, and the other end is fixedly connected to the top end of the hook 7, and the articulated plate 9 is fixedly connected to the fixed column 10.

[0033] Specifically, when the ash bucket rises, the screw column 3 rises, driving the hinged seat 4 to rise synchronously, so that the hinged seat 4 can push the push rod 5, and then the push rod 5 pushes the lifting rod 6 to open outward, so that the lifting rod 6 can drive the ash bucket to rise; conversely, it can drive the ash bucket to descend, and the transmission of the lifting and lowering process is stable, efficient and smooth.

[0034] Furthermore, the driving mechanism includes a worm wheel 12 and a worm 13 that cooperate with each other. The bottom end of the threaded rotating rod 15 is integrally connected with the rotating rod 2. The bottom end of the rotating rod 2 extends into the interior of the base 1 and is fixedly sleeved with the inner ring of the worm wheel 12. The worm 13 is driven to rotate by a motor arranged in the base 1.

[0035] It can be seen from the above description that the transmission of the worm wheel 12 and the worm 13 has high transmission efficiency and stability, which can ensure the stable operation of the device, and arranging the worm wheel 12 and the worm 13 inside the base 1 can also serve as a protective mechanism.

[0036] Furthermore, a lockable universal wheel 14 is installed at the bottom end of the base 1 to facilitate movement.

[0037] Furthermore, the base 1 is a circular block structure, which is convenient and stable to be placed on the ground and can prevent bumps.

[0038] Furthermore, both the screw column 3 and the fixing column 10 are circular cylinders, which facilitates the connection of multiple lifting units.

[0039] Embodiment 2

[0040] See also Figure 3 , Figure 4 and Figure 5 The plaster bucket lifting mechanism of this embodiment is further defined on the basis of the above-mentioned embodiment 1 as follows for the overall mechanical structure of the hook 7:

[0041] See also Figure 3 The hook end of the hook 7 is hinged with a baffle 8, and the free end of the baffle 8 is detachably connected to the hook 7 through a limiting device. The setting of the baffle 8 can close the hook 7 to prevent the plaster bucket from falling out during the lifting process, thereby improving safety.

[0042] Specifically, see Figure 4 The limiting device includes an insertion rod 17, one end of which penetrates the insertion hole 23 provided on the hook 7 and then engages with the groove provided on the free end of the stop rod 8, and an elastic engaging device is provided between the insertion rod 17 and the inner wall of the insertion hole 23. After the plaster bucket is hooked on the hook 7, the insertion rod 17 is inserted through the insertion hole 23 and then engaged with the groove on the stop rod 8, so that the hook 7 can be closed and the stop rod 8 can be prevented from opening. The setting of the elastic engaging device increases the hindering force between the insertion rod 17 and the hook 7, preventing the insertion rod 17 from coming out;

[0043] In this embodiment, one end of the insertion rod 17 away from the blocking rod 8 is fixedly connected to a pull block 16, which facilitates pulling the insertion rod 17 out of the groove on the blocking rod 8, thereby facilitating opening the blocking rod 8.

[0044] For further information, see Figure 5 The insert rod 17 is located inside the hook 7 and has two through holes 19 vertically spaced apart. The elastic engaging device includes a compression spring 20 arranged in the through hole 19, and also includes a push block 21 fixed at both ends of the compression spring 20 and a ball 22 rollingly arranged at the free end of the push block 21. The inner wall of the plug-in hole 23 is provided with three annular grooves 18 at intervals along the length direction, and the two balls 22 on the same side are clamped in two adjacent annular grooves 18.

[0045] From the above description, it can be known that the compression spring 20 pushes the push block 21 out of the through hole 19 and clamps the ball 22 in the annular groove 18. When the insertion rod 17 needs to be withdrawn from the groove on the baffle rod 8, the insertion rod 17 is pulled to make the ball 22 withdraw from the annular groove 18. Continuing to pull the insertion rod 17 can make the ball 22 continue to move in the direction of movement of the insertion rod 17 and be clamped in the next annular groove 18. At this time, the insertion rod 17 is released. When the insertion rod 17 stops moving and the end of the insertion rod 17 just withdraws from the groove on the baffle rod 8, no other control force is required, and plugging and unplugging is more convenient. By setting the elastic locking device, it is convenient to limit the baffle rod 8. At the same time, multiple elastic locking devices can provide a certain resistance to prevent the insertion rod 17 from sliding and facilitate construction personnel to plug and unplug.

[0046] The working principle of the utility model is as follows: before starting the operation, the ash bucket is hung on the hook 7, the lifting unit is in a loose state, and the driving mechanism is in a stopped state; when the ash bucket needs to be lifted, the driving mechanism is started to drive the screw column 3 to start moving upward; as the screw column 3 rotates, the push rod 5 in the lifting unit is pushed upward, pushing the lifting rod 6 and the hook 7 to move upward together, and the hinged design of the lifting rod 6 and the fixed column 10 allows the hook 7 to move upward stably, thereby lifting the ash bucket to a required height;

[0047] When the ash bucket needs to be lowered, the threaded rotating rod 15 can be rotated in the opposite direction by controlling the driving mechanism to make the push rod 5 move downward, thereby moving the ash bucket downward.
