Description

Technical Field

[0001] This utility model relates to the field of handling device technology, and specifically to a convenient handling device. Background Technology

[0002] Currently, the construction industry is developing rapidly, with various sectors such as new energy industries and urban infrastructure construction advancing simultaneously. Construction of large areas of road curbs, drainage ditches, and cable trenches is being carried out concurrently. Traditionally, the transportation of curbs, drainage ditch covers, and cable trench covers involves transporting them in batches to the site using forklifts, followed by manual lifting to the installation site. This process is time-consuming and labor-intensive, and cannot effectively guarantee the construction progress and quality, resulting in a high probability of project delays and significantly increasing the difficulty of construction.

[0003] To address the aforementioned issues, existing technologies employ installation techniques using forklifts and slings for lifting, but these techniques have the following drawbacks:

[0004] Disadvantage 1: The traditional hoisting and installation method uses forklifts to tie and install with slings, which is costly, difficult to tie, inconvenient to thread ropes at the bottom, and has low work efficiency.

[0005] Disadvantage 2: Mechanical construction cannot achieve high-precision placement. After being hoisted to the site, manual adjustment is still required, making it impossible to complete the installation efficiently and quickly.

[0006] Disadvantage 3: Traditional equipment hoisting involves a large lifting range, which can easily cause bumps and damage, leading to quality defects;

[0007] Disadvantage 4: Excessive investment in equipment makes it impossible to reduce costs, improve quality and efficiency, and reduce costs. Utility Model Content

[0008] This utility model provides a convenient handling device, which aims to save manpower and material resources, improve work efficiency, and reduce construction costs.

[0009] This utility model is achieved through the following technical solution: a convenient handling device, including a support frame, a main hanger, a connecting plate, and two sets of clamping rods. The bottom of the support frame is rotatably connected to a roller. One end of the main hanger is connected to the support frame, and the other end of the main hanger is suspended in the air. The connecting plate is rotatably connected to the main hanger. The two sets of clamping rods are located on the front and rear sides of the connecting plate, respectively, and are rotatably connected to the connecting plate. The ends of the two sets of clamping rods away from the connecting plate are connected to symmetrically arranged clamping plates. Both sets of clamping rods are telescopic rod structures.

[0010] Compared with existing technologies, this solution has the following advantages and beneficial effects:

[0011] In this solution, after moving the entire device to the location to be transported, the two sets of clamping booms are rotated to open them and position them above the object being lifted. This allows the clamping plates at one end of the two sets of clamping booms to be positioned on both sides of the object being lifted. Since the clamping booms are telescopic structures, the length of the clamping booms can be adjusted reasonably according to the size of the object being lifted, and the two clamping plates on the two sets of clamping booms can be used to clamp the object being lifted (such as blocks). This solution expands the scope of application.

[0012] Because the main hanger is rotatably connected to the connecting plate, when the two clamps clamp the object being lifted, the support frame is pressed backward, and the object is lifted using the lever principle, thus lifting the object off the ground for easy transportation.

[0013] In this solution, the rollers rotatably connected to the bottom of the support frame make it easier to transport the suspended object. After it is moved to the designated position, the suspended object is placed on the ground, and the telescopic end of the clamping boom is released so that the clamping plate is away from the suspended object. The handling device of this solution does not require manual loading of the suspended object, and the rollers make it easier to transport the suspended object, effectively saving manpower and resources, improving work efficiency, reducing construction costs, and allowing one person to operate and complete the clamping and transportation of the suspended object.

[0014] The convenient handling device in this solution is simple to use and easy to reuse. The rollers change sliding friction to rolling friction, saving time and effort. The clamping rod of this solution is a telescopic structure with adjustable length, which can be adjusted according to the actual site conditions, making it more widely applicable. In addition, the handling device in this solution has a high reusability rate, low requirements for operators, can be learned quickly without separate training, and has low safety risks.

[0015] Furthermore, the support frame includes two parallel uprights, and two rollers are provided. The two rollers are rotatably connected to the bottom of the two uprights respectively. The main hanger is U-shaped, and its two ends are connected to the lower part of the two uprights respectively. The main hanger is inclined and has an inclined angle with the uprights.

[0016] Beneficial effects: The two uprights in this design simplify the entire support frame structure, and the U-shaped main hanger and support frame form a lightweight structure that facilitates transportation and hoisting of the suspended objects. Furthermore, the two rollers make the entire handling device more stable and reduce effort when transporting the suspended objects.

[0017] Furthermore, a connecting rod connects the two uprights.

[0018] Beneficial effects: The connecting rod enhances the stability between the two uprights, forming a unified structure and effectively strengthening the entire support frame.

[0019] Furthermore, each of the two uprights is connected to the main hanger by a reinforcing rod.

[0020] Beneficial effect: The addition of reinforcing bars can further enhance the stability of the connection between the support frame and the main hanger.

[0021] Furthermore, a handle is connected to the top of each of the two uprights.

[0022] Beneficial effects: The handle design makes it convenient for personnel to operate the position of the support frame and facilitates hand gripping and handling.

[0023] Furthermore, an auxiliary rod is vertically connected to the middle of each of the two uprights.

[0024] Beneficial effects: The auxiliary rod can assist in handling and also facilitates support with the ground, making it easy to store and place.

[0025] Furthermore, there are two connecting plates, and two connecting pieces are fixedly connected to the top of the main hanger. The two connecting plates are located between the two connecting pieces, and the two connecting plates are rotatably connected to the two connecting pieces respectively. The two sets of clamping rods are located between the two connecting plates and are rotatably connected to the two connecting plates.

[0026] Beneficial effects: The rotational connection between the two connecting discs and the two connecting plates in this solution can improve the stability of the connection between them. The two connecting discs are designed to limit and stabilize the connection of the clamping rods. The cooperative connection between the two connecting discs, the two connecting plates and the two sets of clamping rods makes the connection between them more stable.

[0027] Furthermore, the connecting disk is a semi-circular disk.

[0028] Beneficial effect: The semi-circular shape of the connecting plate reduces its space occupation, making the whole device more compact.

[0029] Furthermore, the clamping rod includes an outer rod and an inner rod. The outer rod is hollow inside, and one end of the outer rod is rotatably connected to the connecting plate. One end of the inner rod is located inside the outer rod and is slidably engaged with the outer rod. The other end of the inner rod is connected to the clamping plate. A limiting member is provided between the inner rod and the outer rod to restrict the sliding of the inner rod. The inner rod has a plurality of pin holes spaced apart along its length. The lower part of the outer rod has a limiting hole. Sliding the inner rod allows the plurality of pin holes to coincide with the limiting hole respectively. The limiting member can be inserted into the overlapping pin holes and the limiting hole to restrict the sliding of the inner rod.

[0030] Beneficial effects: In this solution, the clamping rod forms a telescopic structure through the outer rod and the inner rod. The inner rod slides along the hollow cavity of the outer rod, thereby changing the length of the entire clamping rod. This makes it easy to adjust the clamping length according to different objects being lifted. The setting of the limiting component makes it easy to limit and fix the position of the inner rod after the length is adjusted.

[0031] In this solution, the position of the inner rod can be fixed and limited by inserting a limiting component into the pin hole and the limiting hole, and by tightening the limiting component. This method is simple to operate and easy to process.

[0032] Furthermore, the end of the clamping plate away from the clamping rod is tilted upward.

[0033] This utility model discloses a convenient handling device that employs a main lifting rod and a telescopic clamping lifting rod in conjunction. Because the clamping plates are tilted upwards, after lifting, the weight of the lifted object forces the inclined clamping plates at both ends to clamp the object tightly, enhancing the clamping effect and preventing the object from falling. This satisfies the requirements for lifting, transporting, and placing blocks. The device is mass-produced on-site before construction, using standard components without any special or difficult-to-procure parts. It is manufactured in a single process, eliminating subsequent maintenance costs and significantly reducing expenses. Installation and dismantling are convenient, reducing labor input and ensuring rapid turnaround, thus greatly guaranteeing the project schedule. Attached Figure Description

[0043] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0044] Example 1

[0045] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a convenient handling device, including a support frame, a main hanger 7, a connecting plate 9, and two sets of clamping rods. Rollers 1 are rotatably connected to the bottom of the support frame. One end of the main hanger 7 is connected to the support frame, and the other end of the main hanger 7 is suspended in the air. Specifically:

[0046] In this embodiment, the support frame includes two parallel uprights 4 and two rollers 1. The two rollers 1 are rotatably connected to the bottom of the two uprights 4 via a pivot 2. In this embodiment, the main hanger 7 is U-shaped, and the two ends of the main hanger 7 are connected to the lower part of the two uprights 4 respectively. In this embodiment, the two ends of the main hanger 7 are welded and fixed to the two uprights 4 respectively. The main hanger 7 is inclined and has an inclined angle with the uprights 4. In this embodiment, the main hanger 7 is inclined from bottom to top away from the uprights 4. The inclined angle between the main hanger 7 and the uprights 4 is preferably 45°.

[0047] A connecting rod is connected between the two uprights 4. In this embodiment, the connecting rod includes a top connecting rod 16 and a middle connecting rod 17. The top connecting rod 16 is located at the top of the two uprights 4, and the middle connecting rod 17 is located in the middle of the two uprights 4. Both the top connecting rod 16 and the middle connecting rod 17 are welded and fixed to the two uprights 4. A reinforcing rod 6 is welded between the two uprights 4 and the main hanger 7. The setting of the reinforcing rod 6 can enhance the stability and connection strength between the uprights 4 and the main hanger 7. A handle 5 is connected to the top of the two uprights 4. In this embodiment, the handle 5 is welded and fixed to the uprights 4, or integrally formed, or threaded. The handle 5 and the uprights 4 are connected by an arc transition, and there is an angle between the handle 5 and the uprights 4. An auxiliary rod 3 is vertically connected to the middle of the two uprights 4. In this embodiment, the auxiliary rod 3 is welded and fixed to the uprights 4.

[0048] The connecting plate 9 is rotatably connected to the main hanger 7. Two sets of clamping rods are located at the front and rear of the connecting plate 9, respectively, and are rotatably connected to it. The ends of the two sets of clamping rods furthest from the connecting plate 9 are each connected to symmetrically arranged clamping plates 13. Specifically, in this embodiment, the connecting plate 9 is a semi-circular plate, combined with 1, Figure 3 and Figure 4 As shown, there are two connecting plates 9, and two connecting pieces 8 are fixedly connected to the top of the main hanger 7. In this embodiment, one end of the connecting piece 8 is welded and fixed to the main hanger 7. Both connecting plates 9 are located between the two connecting pieces 8, and the two connecting plates 9 are rotatably connected to the two connecting pieces 8 respectively. Figure 4 As shown, in this embodiment, both the connecting disc 9 and the connecting piece 8 have overlapping through holes. A disc connecting shaft 14 is inserted into the through holes on the connecting disc 9 and the connecting piece 8. Nuts are threaded onto both ends of the disc connecting shaft 14 to restrict the disc connecting shaft 14 to the connecting disc 9 and the connecting piece 8. The connecting piece 8 and the connecting disc 9 are movably connected through the disc connecting shaft 14, and the connecting piece 8 can rotate along the disc connecting shaft 14.

[0049] Both sets of clamping rods are located between and rotatably connected to the two connecting plates 9. In this embodiment, overlapping through holes are provided on the upper part of the clamping rods and on the connecting plates 9. The connecting shaft 10 of the rod is inserted into the overlapping through holes on the clamping rods and the connecting plates 9, and the two ends of the connecting shaft 10 are fixed with nuts. Figure 1 and Figure 2 As shown, two sets of clamping rods are set one in front of the other on the connecting plate 9, and the connecting piece 8 is rotatably connected to the middle position of the connecting plate 9. By rotating the two sets of clamping rods, the two sets of clamping rods are opened, which makes it easier for the clamping plates 13 on the clamping rods to clamp the suspended object.

[0050] like Figure 2 As shown, in this embodiment, both sets of clamping rods are telescopic rod structures. Specifically, the clamping rods include an outer rod 11 and an inner rod 12. The outer rod 11 is hollow inside. One end of the outer rod 11 is rotatably connected to the connecting plate 9 through the rod connecting shaft 10. One end of the inner rod 12 is located inside the outer rod 11 and is slidably engaged with the outer rod 11. The other end of the inner rod 12 is welded to or screwed to the clamping plate 13. The clamping plate 13 and the clamping rods have an angle, and the angle is less than or equal to 90°. In this embodiment, the clamping plate 13 is perpendicularly connected to the inner rod 12 in the clamping rods.

[0051] A limiting member is provided between the inner hanger 12 and the outer hanger 11 to restrict the sliding of the inner hanger 12. In this embodiment, the inner hanger 12 has a plurality of pin holes 15 spaced apart along its length, and the lower part of the outer hanger 11 has a limiting hole. Sliding the inner hanger 12 can make the plurality of pin holes 15 coincide with the limiting hole respectively. The limiting member can be inserted into the overlapping pin holes 15 and the limiting hole and restrict the sliding of the inner hanger 12. In this embodiment, the limiting member is a bolt. After inserting the bolt into the overlapping pin holes 15 and the limiting hole, the position of the inner hanger 12 after sliding into place can be limited and fixed by fixing it with a nut.

[0052] The specific implementation process is as follows:

[0053] ① This support system can meet the needs of handling and installation of trench covers, cable trench covers and curb stones of various sizes. This utility model is applicable to the handling of structures in the range of 600mm-1600mm. For larger sizes, the length of the lifting rod can be appropriately increased, but the principle is the same.

[0054] ② Based on the extensive dimensions of the materials involved in the project, perform welding and fabrication of the equipment, ensuring that the length of the hanger rods meets the overall length of the structure as much as possible. The specific equipment installation results are as follows: Figure 1 As shown;

[0055] ③ After welding according to the dimensions shown in the diagram, combine... Figure 5 As shown, the device is manually pushed to the top of the cover plate and curb block to be lifted, and the two sets of clamping rods are manually pried open to ensure that the clamping plates 13 at the ends of the two sets of clamping rods are placed at both ends of the structure to be lifted.

[0056] ④ Manually press down the handle 5 and the upright 4 backwards, and the object being hoisted will be lifted by the structure using the lever principle;

[0057] ⑤ Manually push the object to the location where it needs to be installed, lift the handle 5 and the upright 4 upwards, and slowly lower the object to the installation position. If fine adjustments are needed, repeat the lifting and manual pushing for fine adjustments.

[0058] ⑥ After the overall transport is completed, lift the handle 5 and the upright 4 upwards, loosen the clamps 13 at both ends, retract the two sets of clamping rods, and push to the next transported item. Repeat the operation.

[0059] This utility model is applicable to the handling of goods with a fixed shape and a certain strength, making the handling process more labor-saving and improving efficiency. Furthermore, this utility model has a wide range of applications, low cost, fast turnover, simple operation, and convenient processing. This new technology uses the lever principle to change sliding friction into rolling friction, saving both effort and time. This new technology allows for adjustable lengths of the inner and outer lifting rods 12 and 11, which can be adjusted according to actual site conditions, thus broadening its applicability. Moreover, this new technology is uniformly processed before construction, ensuring standardized and consistent equipment, simple operation, and high efficiency. This new technology has a high reusability rate, low operator requirements (it's easy to learn and requires no separate training), and low safety risks.

[0060] Advantages of this utility model:

[0061] (1) The most common conventional materials are used and can be processed on-site. If conditions permit, processing can be carried out in a processing plant. The materials are easy to purchase, which greatly reduces the manufacturing cost. On-site operation and construction are simple and easy to learn and understand.

[0062] (2) The device can be processed and formed in one step, with no maintenance costs in the later stage. It is easy to install and has a high reusability. The fixed position can be adjusted arbitrarily through the pin hole 15 on the inner rod 12 and the limiting hole on the outer rod 11, so that the length of the clamping rod can be changed at will. It has a wider range of applications and can meet the requirements of various sizes of cover plates, blocks and other materials.

[0063] (3) All handling devices adopt a unified standard, and after processing and molding, they are beautiful and elegant, making the construction site clean and beautiful. At the same time, transportation, stacking and storage are convenient, and there is no need to worry about subsequent sorting issues.

[0064] (4) The structure is simple and combines the lever principle to change sliding friction into rolling friction, which saves time and effort and saves costs.

[0065] Example 2

[0066] The difference between this embodiment and embodiment 1 is that: in this embodiment, the end of the clamping plate 13 away from the clamping rod is inclined upward, and the angle between the clamping plate 13 and the clamping rod is less than 90 degrees. In this embodiment, the angle between the clamping plate 13 and the inner rod 12 is preferably 86-89°, so that the clamping plate 13 has a slight inclination.

[0067] Combination Figure 5 and Figure 6As shown, when the support frame swings backward and uses the lever principle to lift the suspended object off the ground, the suspended object will move downward under its own weight. Since there is an angle between the two clamping plates 13 and the inner lifting rod 12, the clamping plates 13 have a slight tilt. Under the action of gravity, the suspended object will force the clamping plates 13 with tilted ends to further clamp the suspended object, enhance the clamping effect of the clamping plates 13 on the suspended object, and make it less likely for the suspended object to fall.

[0068] It should be noted that the above description of the disclosed embodiments enables those skilled in the art to implement or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
