Description
Technical Field
[0001] The utility model belongs to the technical field of hoists, and particularly relates to a construction engineering material hoist. Background Art
[0002] In the construction engineering construction site, materials need to be transported, including horizontal transportation, vertical transportation and inclined transportation. The material hoist is a commonly used transportation equipment for transporting materials in the construction engineering construction site. There are many types of hoists. The small portable loading hoist, also known as a small crane, is a type of hoist and is also a conventional hoisting equipment for hoisting building materials, loading and unloading and transporting materials, and carrying materials in construction engineering construction. The principle of the small crane mainly involves a lifting mechanism, a working mechanism and a control system (composed of a controller, sensors, actuators, etc.). The principle is that the control system controls the lifting mechanism to achieve lifting and hoisting, that is, through the transmission of electrical signals or wireless signals, the operator's instructions are conveyed to the small crane to achieve the operation effect of the lifting mechanism. The lifting mechanism usually includes key components such as a lifting hook, a rope system (such as a steel wire rope), a motor and a reducer. The working principle of lifting is that the motor drives the reducer, and through the rope system (such as a steel wire rope), the lifting hook is lifted or lowered, so as to achieve the lifting and hoisting of an object;
[0003] When the small loading hoist vertically transports building materials, the lifting hook hooks the materials, and the motor drives the reel to rotate and wind the steel wire rope, so that the steel wire rope pulls the lifting hook and the materials to rise, achieving the purpose of lifting the materials; during the long-term and frequent process of lifting materials, due to the support frame of the loading hoist being in an inclined state with one end suspended, and the weights of the lifted materials being inconsistent, the support frame of the loading hoist is prone to cracks or deformation, resulting in vibration or shaking during the use of hoisting and lifting. There is no reinforcement design on the support frame of the loading hoist, and the support frame cannot be further reinforced;
[0004] When the existing loading hoist is in use, there is a problem that the support frame is not further reinforced. For this reason, this application proposes a construction engineering material hoist. Content of the Utility Model
[0005] The purpose of the utility model is to provide a construction engineering material hoist to solve the problem that there is no design for further reinforcing the support frame on the loading hoist proposed in the above background art.

[0011] Preferably, the reinforcing base is a three-dimensional trapezoidal platform structure, the reinforcing plate is a right trapezoidal structure, and the reinforcing plate is provided with a limiting slot c that cooperates with the clamping block.
[0012] Preferably, the reinforcing frame is a right triangle bracket structure. The reinforcing frame includes a vertical right angle end and an inclined brace end. The top end of the column passes through the right angle end of the reinforcing frame and is connected to the brace end.
[0013] Preferably, both the convex block and the limiting block are "L"-shaped structures, and the limiting block is provided with a second slot d that cooperates with the convex block.
[0014] Preferably, one end of the limiting square rod is a right angle end, and the moving leg and the other end of the limiting square rod are provided with through holes through which the limiting rod passes.

Driven by the motor-driven wire rope winding seat 14, the hoisting wire rope 15 lifts the lifting hook 16 and the materials upward. The material hoisting principle is a conventional technology and will not be elaborated in detail in this application. A movable wheel is provided at one end of the movable leg 17, which can be conveniently moved; a support assembly, which includes a fixing plate 21 connected to the base 11, a mounting plate 22 that fits the surface of the fixing plate 21, and a reinforcing base 23 installed on the mounting plate 22. The fixing plate 21 is welded to the base 11, the mounting plate 22 is combined with the fixing plate 21, and the mounting plate 22 is welded to the reinforcing base 23. A clamping block 211 is provided on the fixing plate 21, and the clamping block 211 is welded to the fixing plate 21. A reinforcing plate 231 is provided on the outer surface of the reinforcing base 23. A limiting square rod 221 is provided on the mounting plate 22, and the reinforcing plate 231 is welded to the reinforcing base 23. When the mounting plate 22 is installed on the fixing plate 21, the clamping block 211 penetrates the mounting plate 22 to accurately install the mounting plate 22. The clamping block 211 is embedded inside the corresponding reinforcing plate 231, and then fixed firmly by a locking bolt to stably install the reinforcing base 23. The reinforcing base 23 supports the column 31 and the reinforcing frame 32 to reinforce the support frame 13 and prevent it from deforming, vibrating or shaking during use; a reinforcing component, which includes a column 31 with its lower end embedded inside the reinforcing base 23 and a reinforcing frame 32 connected to the top end of the column 31. The column 31 is firmly connected to the reinforcing base 23 and the reinforcing frame 32 by bolts. The triangular reinforcing frame 32 supports the support frame 13, increases the support points, and keeps it in a firm state to prevent it from deforming; a limiting component, which includes a convex block 111 installed on the base 11, a fixed-connected limiting block 41 and a limiting rod 42. The base 11 is welded to the convex block 111, and the limiting block 41 and the limiting rod 42 are welded together. When the movable wheel at one end of the movable leg 17 is in an upward vertical state, the limiting rod 42 penetrates the movable leg 17 to keep it in a stable state, preventing the movable wheel of the movable leg 17 from being interfered by impurities in a messy construction site, thus causing the situation of the movable wheel being stuck and affecting the movement.
[0027] In this embodiment, a rectangular first card slot b through which the card block 211 penetrates is provided on the mounting plate 22. The reinforcement base 23 is a three-dimensional trapezoidal platform structure, and the reinforcement plate 231 is a right trapezoidal structure. A limiting slot c that cooperates with the card block 211 is provided inside the reinforcement plate 231. The card block 211 penetrates the mounting plate 22 to accurately position the mounting plate 22. The card block 211 is embedded inside the corresponding reinforcement plate 231, and then the reinforcement base 23 is firmly installed through the fastening of the locking bolts.
[0028] In this embodiment, the reinforcement frame 32 is a right triangle bracket structure. The reinforcement frame 32 includes a vertical right-angle end and an inclined brace end. The top end of the column 31 penetrates the right-angle end of the reinforcement frame 32 and is connected to the brace end. The reinforcement base 23 supports the column 31 and the reinforcement frame 32. The triangular reinforcement frame 32 supports the support frame 13, increases the support points, reinforces the support frame 13, and prevents it from deforming, vibrating or shaking during use.

One end of the limiting rod 42 is a right-angle structure. The distance between the moving leg 17 and the convex block 111 is 1 cm larger than the width H. When the moving leg 17 rotates along the a direction, first remove the limiting rod 42. Since there is a distance between the moving leg 17 and the convex block 111, it does not affect the rotation of the moving leg 17.
