Description

Technical Field

[0001] This utility model belongs to the field of handcart technology, specifically relating to a handcart for construction projects that is easy to hoist. Background Technology

[0002] A handcart is a transport vehicle pushed or pulled by human power; it is the ancestor of all vehicles. Although handcart material handling technology has continuously developed, handcarts remain an indispensable transport tool. Handcarts are widely used in production and daily life because they are inexpensive, easy to maintain, convenient to operate, and lightweight. They can work in places where motor vehicles are inconvenient to use, and are very convenient for moving lighter items over short distances. Handcarts are also used in construction.

[0003] Meanwhile, handcarts are used as transport vehicles in construction, and are therefore frequently used for transferring tools between floors. The method of transferring handcarts is by crane. During use, steel cables are used to restrain the handcarts, and then the steel cables are hung on hooks on the crane. However, this method of securing handcarts with steel cables has shortcomings. Specifically, the position of the steel cables is mostly fixed, and the weight of the handcart itself and the two ends after it is filled with building materials will be uneven. It is impossible to ensure balance during hoisting, which can easily cause the building materials in the handcart to spill. In addition, the handcart is prone to spinning after being hoisted, which can easily lead to the risk of the handcart falling.

[0004] The push-pull rod and support rod of the handcart cannot be adjusted, and during the hoisting process, it is easy to bump into or snag other objects, which brings inconvenience and safety to the hoisting and use of the handcart.

[0005] Therefore, in order to solve the above problems, a handcart for construction projects that is easy to lift is provided. Summary of the Invention

[0006] To address the problems mentioned in the background section, this utility model provides a construction trolley that is easy to lift. By adjusting and fixing the adjusting frame and lifting beam on the lifting structure to the appropriate position, the trolley's balance during lifting is ensured, preventing materials from spilling from the hopper, and solving the problem of the trolley easily spinning after being lifted. Adjustable and retractable push-pull rods and support rods are used for easy use during lifting, avoiding contact with or snagging on other objects that could cause safety issues during trolley lifting.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a construction engineering handcart that is easy to hoist, comprising a handcart, a hopper inside the handcart, an adjustable hoisting structure installed above the handcart, the hoisting structure comprising a fixed frame fixedly installed on the rear end of the handcart and an adjusting frame that slides laterally on the handcart, a hoisting beam being longitudinally slidably fitted on the fixed frame and the adjusting frame; a vertically adjustable support rod is slidably provided on the rear end face of the handcart, and a push-pull rod is slidably connected to the rear end of the handcart through a storage cavity.

[0008] As a preferred embodiment, the upper ends of the two side walls of the handcart are provided with first T-shaped sliding grooves, and the two ends of the adjusting frame are slidably set in the first T-shaped sliding grooves through the first T-shaped sliders. The upper and lower surfaces of the fixed frame are provided with limiting sliding strips. One end of the lifting beam is slidably fitted onto the fixed frame through the limiting sliding groove and the limiting sliding strip, and the other end of the lifting beam is slidably fitted onto the adjusting frame. A lifting ring is provided in the middle of the lifting beam. The two ends of the lifting beam are fastened to the fixed frame and the adjusting frame through fastening bolts and fastening screw holes.

[0009] As a preferred embodiment, clamping screws are connected to both ends of the adjustment frame, and clamping screws pass through the interior of the adjustment frame and are connected to clamping plates for clamping the upper surface of the handcart.

[0010] As a preferred embodiment, an adjusting screw is installed on the rear end face of the handcart via a screw seat, and a lifting plate is connected to the adjusting screw via a screw slider. The two ends of the lifting plate slide in the second T-shaped grooves on both sides of the rear end face of the handcart via second T-shaped sliders, and support rods are installed at the bottom of both ends of the lifting plate; an adjusting handle is connected to the top of the adjusting screw.

[0011] As a preferred embodiment, one end of the push-pull rod is slidably disposed in the storage cavity and is connected to the trolley for positioning via a limiting screw and a limiting screw hole.

[0012] As a preferred embodiment, the bottom of the handcart is equipped with wheels connected by a pivot.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention involves moving the adjusting frame on the hoisting structure horizontally above the handcart to a suitable position, and using clamping screws to drive the clamping plate for limiting and fixing; the hoisting beam slides longitudinally along the fixed frame and adjusting frame to adjust the balanced hoisting position and is tightened and limited by fastening bolts; the adjustable hoisting structure ensures the balance of the handcart during hoisting, prevents materials in the hopper from spilling, and solves the problem that the handcart is prone to spinning after being hoisted, which could lead to the risk of the handcart falling.

[0015] Push the push-pull rod into the storage cavity and limit it with the limit screw. Rotate the adjusting handle to drive the adjusting screw to rotate, which will raise the lifting plate and thus retract the lower end of the support rod to be flush with the bottom of the handcart. This prevents the support rod and push-pull rod from easily touching or snagging other objects during hoisting, which would cause inconvenience and safety issues in the hoisting and use of the handcart.

[0029] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0030] Please see Figures 1-5 This utility model provides the following technical solution: a construction engineering handcart that is easy to hoist, including a handcart 1, a hopper inside the handcart 1, an adjustable hoisting structure 2 installed above the handcart 1, the hoisting structure 2 including a fixed frame 21 fixedly installed on the rear end of the handcart 1 and an adjusting frame 22 that slides laterally on the handcart 1, a hoisting beam 23 being longitudinally slidably sleeved on the fixed frame 21 and the adjusting frame 22; a vertically adjustable support rod 5 is slidably provided on the rear end face of the handcart 1, and the rear end of the handcart 1 is limited by a storage cavity 15. The sliding connection includes a push-pull rod 6. In this embodiment, the adjusting frame 22 on the hoisting structure 2 is moved horizontally above the handcart 1 to a suitable position and fixed by the clamping plate 29. The hoisting beam 23 slides longitudinally along the fixed frame 21 and the adjusting frame 22 to adjust the balanced hoisting position and fix it. The adjustable hoisting structure 2 ensures the balance of the handcart 1 during hoisting, prevents the material in the hopper from spilling, and solves the problem that the handcart is prone to spinning after being hoisted, which could lead to the risk of the handcart falling.

[0031] In this embodiment, the upper ends of the two side walls of the handcart 1 are provided with first T-shaped grooves 11. The two ends of the adjusting frame 22 are slidably disposed in the first T-shaped grooves 11 through first T-shaped sliders 25. The upper and lower surfaces of the fixed frame 21 are provided with limiting slide strips 26. One end of the lifting beam 23 is slidably sleeved on the fixed frame 21 through the limiting groove and the limiting slide strip 26, and the other end of the lifting beam 23 is slidably sleeved on the adjusting frame 22. A lifting ring 24 is provided in the middle of the lifting beam 23. The two ends of the lifting beam 23 are fastened to the fixed frame 21 and the adjusting frame 22 through fastening bolts 28 and fastening screw holes 30. The two ends of the adjusting frame 22 are connected with clamping screws 27. The clamping screws 27 pass through the adjusting frame 22 and are connected to clamping plates 29 for clamping the upper surface of the handcart 1. According to the handcart 1 itself and the contents it holds... To assess the weight of the building materials, the adjusting frame 22 can be moved horizontally above the handcart 1 via the first T-shaped slider 25 and the first T-shaped slide groove 11 to a suitable position. The clamping screw 27 is then rotated to clamp the clamping plate 29 onto the upper surfaces of both sides of the handcart 1 for positioning. The lifting beam 23 is then slid longitudinally along the fixed frame 21 and the adjusting frame 22 to adjust the balanced lifting position. Afterward, the fixed frame 21 and the adjusting frame 22 are fixed to the lifting beam 23 using the fastening bolts 28 through the fastening bolt holes 30. Finally, the hook on the crane is hooked onto the lifting ring 24. The adjustable lifting structure 2 ensures the balance of the handcart 1 during lifting, prevents materials from spilling from the hopper, and solves the problem of the handcart easily spinning after being lifted, which could lead to the risk of the handcart falling.

[0032] In this embodiment, an adjusting screw 3 is installed on the rear end face of the handcart 1 via a screw seat. A lifting plate 4 is connected to the adjusting screw 3 via a screw slider. The two ends of the lifting plate 4 slide in the second T-shaped grooves 12 on both sides of the rear end face of the handcart 1 via second T-shaped sliders 41. Support rods 5 are installed at the bottom of both ends of the lifting plate 4. An adjusting handle 31 is connected to the top of the adjusting screw 3. One end of the push-pull rod 6 is slidably disposed in the storage cavity 15 and is limited to the handcart 1 via a limiting screw 13 and a limiting screw hole 14. The push-pull rod 6 is pushed into the storage cavity 15 and limited by the limiting screw 13. The adjusting handle 31 is also rotated to drive the adjusting screw 3 to rotate, thereby driving the lifting plate 4 to rise and thus retracting the lower end of the support rod 5 to be flush with the bottom of the handcart 1. This prevents the support rod 5 and the push-pull rod 6 from easily touching or hooking other objects during the hoisting process, which would cause inconvenience and safety issues in the hoisting and use of the handcart 1.

[0033] In this embodiment, the bottom of the handcart 1 is connected to wheels 7 via a pivot.

[0034] The working principle and usage process of this utility model are as follows: When using this utility model, the worker can adjust the adjusting frame 22 to a suitable position above the handcart 1 by moving the first T-shaped slider 25 through the first T-shaped groove 11 according to the weight of the handcart 1 itself and the weight of the handcart after it is filled with building materials. Then, the worker can rotate the clamping screw 27 to drive the clamping plate 29 to clamp the upper surfaces of both sides of the handcart 1 for limiting the position. Then, the lifting beam 23 is slid longitudinally along the fixed frame 21 and the adjusting frame 22 to adjust the balanced lifting position. After that, the fixed frame 21 and the adjusting frame 22 are fixed to the lifting beam 23 by using the fastening bolt 28 through the fastening screw hole 30. Finally, the hook on the crane is hooked onto the lifting ring 24. The adjustable lifting structure 2 ensures the balance of the handcart 1 during lifting, prevents the materials in the hopper from spilling, and solves the problem that the handcart is prone to spinning after being lifted, which may lead to the risk of the handcart falling.

[0035] Before lifting the trolley 1, push the push-pull rod 6 into the storage cavity 15 and limit it with the limit screw 13. Also, rotate the adjusting handle 31 to drive the adjusting screw 3 to rotate, which drives the lifting plate 4 to rise, thereby retracting the lower end of the support rod 5 to be flush with the bottom of the trolley 1. This prevents the support rod 5 and push-pull rod 6 from easily touching or hooking other objects during the lifting process, which would cause inconvenience and safety problems in the lifting and use of the trolley 1.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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 this utility model should be included within the protection scope of this utility model.
