Abstract
Description
Technical Field
[0001] This utility model relates to the field of handling equipment technology, and more specifically to a handling equipment for handling heavy objects. Background Technology
[0002] Handling equipment refers to various mechanical devices and tools used to move goods, items, or materials between different locations. In modern homes, offices, outdoor public places, factories, construction sites, and other locations, there are many situations where heavy objects need to be moved, such as moving curb stones laid on both sides of the road or heavy equipment in machining operations. All of these require the use of heavy-duty handling equipment to reduce manpower and improve handling efficiency.
[0003] For example, the prior art publication number CN217437555U describes a crane device that facilitates the positioning and handling of heavy objects. This utility model, through the cooperation of a sliding rod, a sliding sleeve, and a connecting plate, can limit the wire rope when it is hoisting heavy objects by using a limiting frame. This reduces the swaying of heavy objects when the crane is handling them, and enables the handling and unloading of heavy objects in a designated area, thereby improving the efficiency of handling heavy objects.
[0004] However, the existing technology described above still has the following problems in use: While setting a sliding sleeve to limit the wire rope can provide a certain degree of restraint, relying solely on the wire rope to lift the heavy object during transport results in a heavy load on the wire rope, making it prone to breakage. Furthermore, the heavy object will cause the wire rope to sway slightly, increasing friction between the wire rope and the sliding sleeve and making it more susceptible to breakage, thus reducing stability and safety. Therefore, this invention provides a highly stable and safe handling device for transporting heavy objects. Utility Model Content
[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides a handling device for transporting heavy objects. The device uses an electric hoist to lift the heavy object and employs a first positioning plate and two second positioning plates to firmly clamp and fix it. This effectively suppresses the swaying of the heavy object during transport, preventing the stability of the handling frame from being affected by a shift in the center of gravity, thus ensuring the safety of the transport operation. Furthermore, the positions of the first and second positioning plates are adjustable, effectively improving the device's adaptability to heavy objects of different specifications, thereby solving the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a handling device for moving heavy objects, including a handling frame, a crossbeam rail fixedly provided on the top of the handling frame, an electric hoist for lifting heavy objects installed on the crossbeam rail, a positioning component provided inside the handling frame, the positioning component including first positioning plates distributed on both sides of the electric hoist, second positioning plates provided on the front and rear sides of the two first positioning plates, two vertically distributed mounting grooves opened on the outer walls of the front and rear sides of the first positioning plates, an electric push rod fixedly provided inside the mounting groove, one end of the piston rod of the electric push rod being connected to the second positioning plate, and a drive mechanism for driving the first positioning plates to move fixedly provided on both sides of the top of the handling frame.
[0007] In a preferred embodiment, the driving mechanism includes linear modules fixed to the inner wall of the top of the transport frame. The bottom ends of the slides of the two linear modules are respectively fixed to the tops of the two first positioning plates. The linear modules drive the first positioning plates to move horizontally, thereby automatically adjusting the positions of the first and second positioning plates. This is very time-saving and labor-saving, and can improve the transport efficiency.
[0008] In a preferred embodiment, two symmetrically distributed slide rails are provided between the two linear modules. Both slide rails are fixedly embedded on the inner wall of the top of the transport frame. A slider is fixedly provided on the top of each of the two first positioning plates. The slider is located inside the slide rail. By using the slider and the slide rail in cooperation, the stability of the movement of the first positioning plate can be further improved.
[0009] In a preferred embodiment, both first positioning plates have L-shaped cross sections, and both first and second positioning plates have multiple rectangular through holes arranged in a linear array. The presence of multiple rectangular through holes on the first and second positioning plates can reduce their weight, thereby reducing the weight of the entire handling frame to a certain extent and reducing the resistance to pushing by the workers.
[0010] In a preferred embodiment, two movable wheels are fixedly provided on both sides of the bottom end of the transport frame, and two fixed legs are provided on the side of the two movable wheels that are far apart from each other. The fixed legs are threadedly connected to the transport frame. When lifting heavy objects, the fixed legs are turned to contact the ground, which can play a braking role and prevent the transport frame from shaking and affecting the safety of lifting heavy objects.
[0011] In a preferred embodiment, handles are fixedly provided on both outer walls of the transport frame. The handles are located above the fixed legs. The handles facilitate the operator's control of the transport frame's forward direction, thereby improving the stability of the transport frame's movement.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] This utility model uses an electric hoist to lift heavy objects and uses two opposing first positioning plates and two second positioning plates on the first positioning plates to firmly clamp and fix the heavy objects, which can effectively suppress the shaking of heavy objects during transportation, prevent the stability of the transportation frame from being affected by the shift of the center of gravity, and thus ensure the safety of transportation operations.
[0014] In addition, by adjusting the position of the first positioning plate through a linear module and flexibly adjusting the position of the second positioning plate with an electric push rod, the equipment's adaptability to heavy objects of different specifications is effectively improved.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Refer to the instruction manual appendix Figures 1-5This utility model provides a handling device for moving heavy objects, including a handling frame 1. A crossbeam rail 2 is fixedly provided on the top of the handling frame 1. An electric hoist 3 for lifting heavy objects is installed on the crossbeam rail 2. The electric hoist 3 is usually equipped with wheels for moving on the crossbeam rail 2. It is mounted on the crossbeam rail 2 by a trolley. The electric hoist 3 transmits the shaft power and torque of its internal motor to the reduction gear through a coupling. The gearbox converts high-speed rotation into low-speed, high-torque output, and then transmits the power to the drum through gear transmission. The rotation of the drum causes the wire rope to wind or unwind, thereby driving the hook to lift and lower the heavy object.
[0025] The transport frame 1 is equipped with a positioning component 4. The positioning component 4 includes first positioning plates 41 distributed on both sides of the electric hoist 3. Second positioning plates 42 are provided on the front and rear sides of the two first positioning plates 41. Two vertically distributed mounting grooves 43 are opened on the outer walls of the front and rear sides of the first positioning plates 41. An electric push rod 44 is fixedly installed inside the mounting groove 43. One end of the piston rod of the electric push rod 44 is connected to the second positioning plate 42.
[0026] Both sides of the top of the transport frame 1 are fixed with drive mechanisms 5 for moving the first positioning plate 41. Specifically, the drive mechanism 5 includes linear modules 51 fixed on the inner wall of the top of the transport frame 1. The linear module 51 is a mechanical transmission device that can provide linear motion. The bottom ends of the slides of the two linear modules 51 are respectively fixed to the top of the two first positioning plates 41. In addition, two symmetrically distributed slide rails 52 are provided between the two linear modules 51. The two slide rails 52 are fixedly embedded on the inner wall of the top of the transport frame 1. The top of the two first positioning plates 41 are fixed with sliders 53. The sliders 53 are located in the slide rails 52. By using the sliders 53 and the slide rails 52 to cooperate, the stability of the movement of the first positioning plate 41 can be further improved.
[0027] Two movable wheels 7 are fixedly installed on both sides of the bottom end of the transport frame 1. Two fixed legs 8 are installed on the side of the two movable wheels 7 that are far apart from each other. The fixed legs 8 are threadedly connected to the transport frame 1. When lifting heavy objects, the fixed legs 8 are turned to contact the ground, which can play a braking role and prevent the transport frame 1 from shaking and affecting the safety of lifting heavy objects.
[0028] In actual use, the operator first moves the transport frame 1 to the location of the heavy object. Then, using the remote control on the electric hoist 3, the hook of the electric hoist 3 is connected to the chain on the heavy object. The electric hoist 3 can then be used to wind up the wire rope on the hook to lift the heavy object from the ground. Simultaneously, the motor of the linear module 51 drives the ball screw to rotate. The slide on the ball screw is connected to the first positioning plate 41. When the screw rotates, the slide moves linearly under the action of the screw, thereby driving the first positioning plate 41 connected to it to move towards the heavy object until the first positioning plate 41 is in contact with the side wall and bottom wall of the heavy object. Furthermore, by using the electric push rod 44 to adjust the position of the second positioning plate 42, so that the two second positioning plates 42 contact the front and rear walls of the heavy object respectively, the transport frame 1 can be moved to transport the heavy object. The design of the first positioning plate 41 and the second positioning plate 42 can firmly clamp the heavy object, preventing the center of gravity from shifting due to the swaying of the heavy object during the transport process, which would affect the stability of the transport frame 1. When unloading, the linear module 51 moves the first positioning plate 41 and the second positioning plate 42 away from the heavy object, and then the operator uses the remote control of the electric hoist 3 to control the release of the hook, so that the heavy object can be placed on the ground.
[0029] like Figure 1 As shown, the cross-section of both first positioning plates 41 is L-shaped, and multiple rectangular through holes 6 arranged in a linear array are provided on both first positioning plates 41 and two second positioning plates 42. Providing several rectangular through holes 6 on the first positioning plates 41 and the second positioning plates 42 can reduce their weight.
[0030] like Figure 1 As shown, handles 9 are also fixedly installed on both outer walls of the transport frame 1. The handles 9 are located above the fixed legs 8, and the handles 9 are provided to facilitate the staff to control the forward direction of the transport frame 1.
[0031] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
