Description

Technical Field

[0001] The utility model relates to the technical field of lifting carts, and more specifically to a simple lifting cart for construction engineering. Background Art

[0002] On construction sites, building materials often need to be hoisted to higher places. For some smaller building materials that need to be hoisted to lower places, simple hoisting carts are often used to assist construction workers in hoisting the building materials for moving and transportation.

[0003] At present, in the process of lifting construction materials by a lifting cart, since the ground of the construction site is generally not flat, the lifting cart is bumpy and swaying during movement, resulting in the lifting of construction materials. The lifting carts in the prior art generally directly suspend construction materials for transportation and lack corresponding fixing mechanisms, which causes the lifting construction materials to easily collide with foreign objects or tilt and fall due to excessive shaking, thereby affecting the lifting efficiency of the construction materials. Therefore, there is an urgent need to improve the technology of the lifting cart structure to improve this equipment.

[0004] Therefore, the utility model provides a simple lifting cart for construction engineering. Utility Model Content

[0006] In view of the problems existing in the prior art, the purpose of the utility model is to provide a simple lifting cart for construction projects, which can be achieved in the process of lifting and placing building materials. Construction workers can push the pull rod to the right by their feet, drive the movable splint to move to the right, and squeeze the spring to leave space on the upper end of the placement seat, thereby facilitating the placement of building materials. Then, after loosening the pushing force, the elastic reset effect of the spring is used to drive the movable splint to cooperate with the fixed plate to clamp and fix the building materials, so that the building materials are not easily collided or tilted and fell due to the influence of bumps and shaking during the lifting process, thereby improving the lifting stability and effectively improving the lifting efficiency.

[0007] 2. Technical solution
