Description

Technical Field

[0001] This utility model relates to the technical field of lifting and transporting devices, specifically a small lifting and transporting device for construction. Background Technology

[0002] Lifting and transporting equipment is a type of mechanical equipment used to lift, raise, and transport objects horizontally. It is widely used in many fields such as construction, logistics, and ports. Common types include cranes, forklifts, and winches. In small construction sites, corresponding small lifting and transporting equipment is often used to move materials.

[0003] The existing utility model with authorization announcement number CN220376147U discloses a TBM construction lifting device. By making the first and second limiting members slide or roll against the slide rail, it can limit the sliding direction of the support mechanism, thereby preventing the support mechanism from derailing and ensuring the safety of the gantry crane. At the same time, the first and second limiting members can roll or slide relative to the slide rail without hindering the sliding of the support mechanism, thus ensuring the normal use of the gantry crane.

[0004] While the above technical solution offers high safety, it fails to consider that the objects being lifted are generally heavy and have significant inertia. The lack of a stabilizing structure to enhance the stability of the object during transport makes it prone to swaying due to the start-up, shutdown, or rotation of the device, thus increasing the risk of transport hazards.

[0005] Therefore, those skilled in the art have provided a small lifting and transport device for construction to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to provide a small lifting and transport device for construction, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A small lifting and transporting device for construction includes a main frame, an electric hoist is fixedly connected to the inner top wall of the main frame, and a stabilizing mechanism is provided inside the main frame.

[0009] The stabilization mechanism includes two electric telescopic rods. Each electric telescopic rod has a bearing plate fixedly connected to its telescopic end. Each bearing plate has a stabilization plate on its outer side. The two stabilization plates are fixedly connected to a buffer pad on their adjacent sides. The two bearing plates are fixedly connected to four dampers on their adjacent sides. Each damper has a buffer spring sleeved on its outer surface. A button controller is fixedly connected to the left side of the main frame.

[0010] As a further embodiment of this utility model: the outer surface of each of the electric telescopic rods is fixedly connected to the inner wall of the main frame; the telescopic end of each of the dampers is fixedly connected to the side of the stabilizing plate near the bearing plate; the two ends of each of the buffer springs are respectively in contact with the outer surface of the bearing plate and the outer surface of the stabilizing plate; the electric hoist and the two electric telescopic rods are electrically connected to the button controller through wires; two base plates are fixedly connected to the bottom surface of the main frame; and two universal wheels are fixedly connected to the bottom surface of each base plate.

[0011] As a further improvement of this utility model: two connecting plates are fixedly connected to the upper surface of each base plate, and a traction hook is fixedly connected to the side of each connecting plate away from the main frame.

[0012] As a further improvement of this utility model: a nut cylinder is fixedly connected to the bottom surface of each base plate, and a threaded rod is threadedly connected to the inner wall of each nut cylinder.

[0013] As a further improvement of this utility model: each of the threaded rods is fixedly connected to a stop seat at its bottom end, and each of the stop seats is fixedly connected to an anti-slip pad on its bottom surface.

[0014] As a further improvement of this utility model: two bent handles are fixedly connected to both the front and back of the main frame, and an anti-slip sleeve is fixedly connected to the outer surface of each bent handle.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention utilizes the coordinated operation of a main frame, electric hoist, electric telescopic rod, button controller, load-bearing plate, stabilizing plate, buffer pad, damper, and buffer spring. When energized, the electric hoist can lift and lower heavy objects. The button controller controls the extension and retraction lengths of the two electric telescopic rods. Furthermore, the two sets of stabilizing plates and buffer pads work together to clamp heavy objects of different sizes with appropriate force from both sides. The damper and buffer spring provide good cushioning between the load-bearing plate and the stabilizing plate, significantly increasing the stability of the lifted object. This prevents the lifted object from swaying due to the start-stop or rotation of the device, thus increasing the safety of the entire transport process. It avoids the problem of dangerous transport caused by the lack of a stabilizing structure to enhance the stability of the lifted object during transport, which could lead to swaying during the start-stop or rotation of the device.

[0022] Please see Figure 1-4 A small lifting and transport device for construction includes a main frame 1. An electric hoist 2 is fixedly connected to the inner top wall of the main frame 1. The electric hoist 2 adopts existing mature technology and can lift and lower heavy objects when powered on. A stabilizing mechanism 3 is set inside the main frame 1. The stabilizing mechanism 3 includes two electric telescopic rods 301. The telescopic end of each electric telescopic rod 301 is fixedly connected to a bearing plate 303. The outer surface of each electric telescopic rod 301 is fixedly connected to the inner wall of the main frame 1. Two base plates 4 are fixedly connected to the bottom surface of the main frame 1. Two casters 5 are fixedly connected to the bottom surface of each base plate 4. By setting the base plates 4, the stability of the bottom surface of the main frame 1 can be increased. By setting the casters 5, the multi-directional movement and transportation of the entire device can be facilitated.

[0023] Each load-bearing plate 303 is equipped with a stabilizing plate 304 on its outer side. The two stabilizing plates 304 are fixedly connected to a buffer pad 305 on their sides that are close to each other. Two connecting plates 6 are fixedly connected to the upper surface of each base plate 4. A traction hook 7 is fixedly connected to the side of each connecting plate 6 that is away from the main frame 1. By setting the connecting plate 6, the traction hook 7 and the base plate 4 can be connected. By setting the traction hook 7, it is convenient to connect to the external traction structure, thereby making it easier and less strenuous to pull the entire device that is carrying heavy objects.

[0024] Four dampers 306 are fixedly connected to one side of each of the two bearing plates 303 that are close to each other. The telescopic end of each damper 306 is fixedly connected to the side of the stabilizing plate 304 that is close to the bearing plate 303. A nut sleeve 10 is fixedly connected to the bottom surface of each base plate 4. A threaded rod 11 is threadedly connected to the inner wall of each nut sleeve 10. By setting the nut sleeve 10, a base surface for the threaded rod 11 to move up and down can be provided. By setting the threaded rod 11, its up and down movement can control the distance between its bottom end and the ground.

[0025] Each damper 306 has a buffer spring 307 fitted on its outer surface. The two ends of each buffer spring 307 are in contact with the outer surface of the bearing plate 303 and the outer surface of the stabilizing plate 304, respectively. Each threaded rod 11 has a parking seat 12 fixedly connected to its bottom end. Each parking seat 12 has an anti-slip pad 13 fixedly connected to its bottom surface. By setting the parking seat 12, the entire transport device can be held against the ground when it is temporarily and stably parked. By setting the anti-slip pad 13, the anti-slip properties of the bottom surface of the parking seat 12 can be increased, thereby increasing the parking stability of the entire device when the parking seat 12 is held against the ground.

[0026] A button controller 302 is fixedly connected to the left side of the main frame 1. The button controller 302 can be an MCU or an Arduino series. It is small in size, low in cost and low in power consumption, and suitable for miniaturization and embedded applications. It can control multiple components through programming. It can be connected to the control terminal of each electrical component through digital output pins and control the power of each component through analog output pins. Specific control logic and timing can be implemented by writing code. The electric hoist 2 and the two electric telescopic rods 301 are electrically connected to the button controller 302 through wires. Two bending handles 8 are fixedly connected to the front and back of the main frame 1. Each bending handle 8 has an anti-slip sleeve 9 fixedly connected to its outer surface. By setting the bending handles 8, it is convenient to pull and adjust the movement and transport direction of the entire device by hand. By setting the anti-slip sleeves 9, the anti-slip properties of the outer surface of the bending handles 8 can be increased.

[0027] The working principle of this utility model is as follows: During use, the operation button controller 302 controls the power supply of the electric hoist 2, thereby facilitating the lifting and lowering of heavy objects to be hoisted and transferred. When the heavy object lifted by the electric hoist 2 rises between the two buffer pads 305, the operation button controller 302 controls the extension and retraction length of the two electric telescopic rods 301 respectively, until the two sets of stabilizing plates 304 and the buffer pads 305 together properly clamp the sides of the heavy objects of different sizes. Meanwhile, the damper 306 and the buffer spring 307 form a good buffer between the bearing plate 303 and the stabilizing plate 304, thereby greatly increasing the load on the electric hoist. The stability of the hoisting device 12 is designed to prevent the hoisted object from swaying due to the start-up, stop-start, or rotation of the device, thereby increasing the safety of the entire device during transportation. When the entire device needs to be temporarily stabilized and stopped, the stop seat 12 is turned so that the threaded rod 11 rotates along the inner thread of the nut sleeve 10 until the anti-slip pad 13 on the bottom of the stop seat 12 is pressed against the ground. The design of the entire small hoisting and transportation device for construction effectively solves the problem that the hoisted object is prone to swaying due to the start-up, stop-start, or rotation of the device due to the lack of a stabilizing structure to increase the stability of the hoisted object during transportation, which could easily lead to transportation danger.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
