Description

Technical Field

[0001] The utility model relates to the technical field of material handling devices, in particular to a material handling and lifting device based on building construction. Background Art

[0002] Construction refers to the production activities in the implementation stage of engineering construction, and is the construction process of various types of buildings. During the construction process, a lot of construction materials need to be transported to high altitudes for construction, so lifting devices are often used.

[0003] The existing lifting device uses a traction machine to drive the lifting cable to lift up and down, and the lifting cable will be limited and guided by the supporting roller on the top of the support frame, so that the supporting roller itself bears a large pressure. As the cable drives the lifting car up and down, a large wear force will be generated between the supporting roller and the cable. After long-term use, the cable will be damaged when it is severely worn, resulting in the risk of the lifting car falling. For this reason, we propose a material handling lifting device based on construction. Utility Model Content

[0007] Preferably, the end of the telescopic rod is engaged with the inner limit of the limit sleeve through a limit clamp, and a support spring connected to the limit clamp is arranged inside the limit sleeve.

[0008] Preferably, when the sealing gasket is retracted into the inner cavity under pressure, the sealing gasket is in a squeeze state against the support spring through the limit clamp at the end of the telescopic rod. When the sealing gasket is without pressure, the sealing gasket is located inside the liquid guide hole through the support spring to rebound and reset to a sealed state.

[0009] Preferably, a filling hole penetrating the inner cavity is provided on the surface of one end of the support guide wheel, and a sealing plug is clamped inside the filling hole.

[0010] Preferably, a first drive chassis and a second drive chassis with motors inside are respectively installed at the front and rear positions of the top of the base, and the output shaft ends of the motors inside the first drive chassis and the second drive chassis are drivingly connected with a first drive shaft and a second drive shaft that pass through the first drive chassis and the second drive chassis respectively, and the ends of the first drive shaft and the second drive shaft are both equipped with docking flanges for docking installation, and the interior of the docking flange is threadedly connected with fixing bolts in the screw groove.

[0013] Beneficial Effects

[0014] The utility model provides a material handling and lifting device based on construction, which has the following beneficial effects:

[0015] (1) A material handling and lifting device based on construction, in this article, a lubricant is stored in the inner cavity of the support guide wheel, and the lubricant in the inner cavity is in a sealed state by the sealing gasket in the liquid guide hole in a default state, and the lifting cable is supported and connected with the surface of the support guide wheel. As the support guide wheel rotates, the lifting cable contacts and squeezes the sealing gasket in the liquid guide hole, and the sealing gasket can be limitedly extended and retracted into the inner cavity through the telescopic rod. At this time, the lubricant in the inner cavity can be discharged outward through the liquid guide hole to contact the surface of the lifting cable, thereby reducing the friction between the lifting cable itself and the surface of the support guide wheel, and further reducing the wear of the lifting cable itself, thereby improving the protection effect of the lifting cable itself, ensuring the normal and stable operation of the lifting cable for the car, and avoiding the risk of the car falling.

[0016] (2) A material handling and lifting device based on construction, wherein the lifting cable is supported and lifted by a supporting guide wheel, one end of the lifting cable is fixed to the top of the car, and the other end of the lifting cable is wound and connected to the first drive shaft on one side of the first drive chassis. The first drive chassis and the second drive chassis are arranged above the base, and the first drive shafts of the first drive chassis and the second drive chassis themselves are docked and installed with the second drive shaft through docking flanges. In this way, when the motor inside the first drive chassis controls the operation of the car through the lifting cable, the motor inside the second drive chassis can simultaneously work to increase the traction tension on the lifting cable. When the first drive chassis itself fails and cannot operate, the second drive chassis can continue to drive the lifting cable through the second drive shaft. The two are similar, so as to avoid the car from stalling and falling, thereby improving the protection effect of the car. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In contrast, an inner cavity 10 for storing lubricating oil is provided inside the support guide wheel 6, a liquid guide hole 11 penetrating the inner cavity 10 is provided on the inner side of the support guide wheel 6, a sealing gasket 12 is provided inside the liquid guide hole 11, a telescopic rod 14 supported and connected to the end of the sealing gasket 12 is provided in a limiting sleeve 13 on the inner surface of the support guide wheel 6, the end of the telescopic rod 14 is limitedly engaged with the inner limit of the limiting sleeve 13 through a limiting clamp 15, a supporting spring 16 supported and connected to the limiting clamp 15 is provided inside the limiting sleeve 13, a filling hole 17 penetrating the inner cavity 10 is provided on the surface of one end of the support guide wheel 6, and a sealing plug 18 is provided inside the filling hole 17 to seal the inner portion. A first drive chassis 19 and a second drive chassis 20 with motors inside are respectively installed at the front and rear positions of the top of the base 1. The output shaft ends of the motors inside the first drive chassis 19 and the second drive chassis 20 are drivingly connected to a first drive shaft 21 and a second drive shaft 22 that pass through the first drive chassis 19 and the second drive chassis 20 respectively. The ends of the first drive shaft 21 and the second drive shaft 22 are both installed with docking flanges 23 that are docked. The interior of the docking flange 23 is threadedly connected with a fixing bolt 25 in a screw groove 24. A limiting disk 26 is installed on the outside of the first drive shaft 21. The other end of the lifting cable 9 passes through the top plate 3 and is wound and connected to the first drive shaft 21.

[0030] Furthermore, when the side of the sealing gasket 12 away from the limiting sleeve 13 is entangled and squeezed with the lifting cable 9, the sealing gasket 12 is located inside the inner cavity 10 through the liquid guide hole 11 and is in a telescopic state.

[0033] The working principle of this utility model:

[0034] The interior of the support guide wheel 6 stores a lubricant in the inner cavity 10, and the lubricant in the inner cavity 10 is in a sealed state by the sealing gasket 12 in the liquid guide hole 11 in the default state, and the lifting steel cable 9 is supported and connected with the surface of the support guide wheel 6. As the support guide wheel 6 rotates, the lifting steel cable 9 contacts and squeezes the sealing gasket 12 in the liquid guide hole 11, and the sealing gasket 12 can be limitedly extended and retracted into the inner cavity 10 through the telescopic rod 14. At this time, the lubricant in the inner cavity 10 can be discharged outwardly through the liquid guide hole 11 to contact the surface of the lifting steel cable 9, reducing the friction between the lifting steel cable 9 itself and the surface of the support guide wheel 6, and further reducing the wear of the lifting steel cable 9 itself, thereby improving the protection effect of the lifting steel cable 9 itself, ensuring the normal and stable operation of the car 4 by the lifting steel cable 9, and avoiding the risk of the car 4 falling. The steel cable 9 is supported and hoisted by the support guide wheel 6. One end of the hoisting steel cable 9 is hoisted and fixed to the top of the car 4, and the other end of the hoisting steel cable 9 is wound and connected with the first drive shaft 21 on one side of the first drive chassis 19. The first drive chassis 19 and the second drive chassis 20 are arranged above the base 1, and the first drive shaft 21 of the first drive chassis 19 and the second drive chassis 20 are docked and installed with the second drive shaft 22 through the docking flange 23. In this way, when the motor inside the first drive chassis 19 controls the operation of the car 4 through the hoisting steel cable 9, the motor inside the second drive chassis 20 can simultaneously work to increase the traction tension on the hoisting steel cable 9. When the first drive chassis 19 itself fails and cannot operate, the second drive chassis 20 can continue to drive the hoisting steel cable 9 through the second drive shaft 22. The same is true for both, so as to avoid the car 4 from stalling and falling.
