Description

Technical Field

[0001] The utility model relates to the technical field of transport tools, in particular to a portable transport tool. Background Art

[0002] Equipment maintenance is a frequent occurrence in machinery manufacturing companies, especially when heavy objects like motors and gearboxes need to be removed or installed. This often relies on lifting equipment like overhead cranes or forklifts. However, when maintenance work requires confined spaces, these lifting equipment often cannot access them, making the removal and installation of heavy objects difficult and, in turn, hindering the normal progress of equipment maintenance.

[0003] In the prior art, for example, the patent with announcement number CN221420431U discloses a lightweight and movable lever-type lifting device, which is adapted to portable lifting and transportation of heavy objects of different weights by cooperating with a lever and a cross tube of a bracket, utilizing the lever principle and adjusting the lever's lever arm length. Although this lifting device can be used to transport heavy objects in a narrow space, due to its design limitations, the hook is located at the end of the lever and is close to the lever's rotation fulcrum, which limits the angle of the lever when it is pressed down and turned, and is only applicable to heavy objects of smaller heights. When the heavy object is of greater height, the downward stroke of the lever is constrained by pressing down on one end of the lever's long lever arm, and cannot provide sufficient lifting height for tall heavy objects, thereby failing to lift tall heavy objects, thereby limiting the adaptability of the tooling to the transportation needs of heavy objects of different heights.

[0028] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] like Figure 1 As shown, combined Figure 2 and 4 The embodiment of the utility model discloses a portable transfer tool, including a lever 1, a mobile support component 2 and a hanging component 3.

[0030] The lever 1 has a first lever arm section 11 and a second lever arm section 12 along its axial direction, wherein the first lever arm section 11 is shorter and the second lever arm section 12 is longer. This design allows the lever 1 to adjust the lever arm length as needed to adapt to different operating conditions.

[0031] The movable support assembly 2 includes a first sleeve 21 and a movable frame 22 fixedly arranged at the bottom of the first sleeve 21. The first sleeve 21 is sleeved on the lever 1 and can slide along the axial direction of the lever 1 within the first force arm section 11. A first locking device 23 is fixedly arranged on the first sleeve 21 for releasing or locking the position of the first sleeve 21 on the lever 1.

[0032] The movable support assembly 2 can adjust the supporting force point of the lever 1, that is, the length of the lever arm, according to the weight of the heavy object during operation, thereby improving the flexibility and stability of the operation.

[0033] The hanging assembly 3 includes a second sleeve 31 and a hanging part 32 fixedly provided at the bottom of the second sleeve 31. The second sleeve 31 can be sleeved on the lever 1 on either side of the first sleeve 21, and the second sleeve 31 can slide along the axial direction of the lever 1 within the area of the first force arm section 11. A second locking device 33 is fixedly provided on the second sleeve 31, which is used to release or lock the position of the second sleeve 31 on the lever 1.

[0034] The hanging assembly 3 can slide on the first arm section 11 of the lever 1, so that the hanging position can be adjusted according to the height requirement of the heavy object, thereby adapting to heavy objects of different heights.

[0035] Specifically, when the suspension assembly 3 is positioned at the end of the first lever section 11 away from the second lever section 12 (i.e., the front end of the lever 1), the second lever section 12 is depressed, making it suitable for lifting relatively light objects. In this case, the long lever section 1 provides a greater torque, making it easier to lift relatively heavy objects that are relatively low in height.

[0036] When the suspension assembly 3 is positioned at the end of the first lever section 11 near the second lever section 12, the second lever section 12 is lifted upward, making it suitable for lifting taller objects. In this case, the short lever arm of the lever 1 provides a smaller torque, but due to the height of the object, lifting the object by lifting the lever 1 upward is more suitable.

[0037] The portable transfer tool disclosed in this utility model utilizes the sliding and locking functions of the mobile support assembly 2 and the hanging assembly 3, allowing the operator to flexibly adjust the support and hanging points of the lever 1 according to the height and weight of different loads, ensuring that the load remains balanced and stable during the lifting process, improving the ease and safety of operation. The portable transfer tool can be used in various site conditions, especially in confined spaces. By adjusting the position and length of the lever arm segment, it can adapt to different lifting requirements, achieving efficient equipment maintenance and heavy object transfer.

[0038] In order to adjust the position of the movable support assembly 2 and the hanging assembly 3 on the lever 1, this embodiment further provides a plurality of locating holes 10 at equal intervals along the length of the lever 1 in the first lever section 11. The first locking device 23 is used to cooperate with the locating holes 10 to keep the first sleeve 21 and the lever 1 locked in position. By inserting or fixing the first sleeve 21 in different locating holes 10, the first sleeve 21 can be locked in different positions on the first lever section 11. The second locking device 33 is used to cooperate with the locating holes 10 to keep the second sleeve 31 and the lever 1 locked in position. Similarly, the second locking device 33 cooperates with the locating holes 10 to provide adjustment and fixation of the position of the second sleeve 31.

[0039] Through multiple positioning holes 10, the user can flexibly adjust the position of the first sleeve 21 and the second sleeve 31 on the lever 1 according to the weight of the heavy object and the lifting requirements. This setting can accurately adjust the length of the lever arm, thereby controlling the torque and lifting force.

[0040] Since different objects have different weights and heights, the multiple positioning holes 10 provide a high degree of flexibility, allowing the portable transfer tool to adapt to a variety of objects and working environments. For example, for heavier objects, a longer lever arm can be selected to reduce the required force, while for lighter objects, a shorter lever arm can be selected to improve operational efficiency.

[0041] In this embodiment, the first locking device 23 and the second locking device 33 have the same structure. As some preferred embodiments, the first locking device 23 includes a cylinder 231 , a positioning rod 232 , an elastic member 233 , a cover plate 234 and a limit plate 235 .

[0042] The outer surface of the first sleeve 21 is provided with a through hole 211, and the cylinder 231 is vertically fixedly provided on the outer surface of the first sleeve 21, and the cylinder 231 is coaxial with the through hole 211. The positioning rod 232 is coaxially provided in the cylinder 231. One end of the positioning rod 232 is movable through the bottom end of the cylinder 231 and the through hole 211, and is used to connect with the positioning hole 10, playing the role of positioning and fixing the lever 1. The limiting plate 235 is located in the cylinder 231 and is fixedly connected to the positioning rod 232, and is used to limit the up and down movement range of the positioning rod 232. The cover plate 234 is fixedly provided at the open end of the top surface of the cylinder 231, and plays the role of closing the cylinder 231 and guiding the movement of the positioning rod 232. The other end of the positioning rod 232 is movable through the outside of the cover plate 234. The elastic member 233 is sleeved on the positioning rod 232, and one end thereof abuts against the limiting plate 235, and the other end abuts against the inner top surface of the cover plate 234. The elastic member 233 provides elastic force to keep the positioning rod 232 connected to or disconnected from the positioning hole 10.

[0043] With the above technical solution, in the absence of external force, the positioning rod 232 has the potential energy to move downward along the cylinder 231 under the elastic force of the elastic member 233, and the lower end of the positioning rod 232 passes through the bottom end of the cylinder 231 and the through-hole 211 in the first sleeve 21. When the first sleeve 21 needs to be installed on the lever 1 and its position needs to be adjusted, the positioning rod 232 is first pulled upward. Under the upward force, the positioning rod 232 compresses the elastic member 233 through the limit plate 235, causing the positioning rod 232 to move upward and disengage from the through-hole 211. At this time, the first sleeve 21 is placed on the lever 1 and manually slid. When the first sleeve 21 is positioned on the lever 1 and the positioning rod 232 is aligned with the corresponding positioning hole 10, the pulling force of the positioning rod 232 is released. Under the action of the elastic member 233, the positioning member moves downward and is inserted into the positioning hole 10, thereby maintaining the first sleeve 21 and the lever 1 relatively fixed.

[0044] It is worth noting that the working principles of the second locking device 33 and the first locking device 23 are the same and will not be described in detail here.

[0045] The first locking device 23 disclosed in this embodiment facilitates and reliably positions and locks the sleeve and lever 1 through the clever coordination of the cylinder 231, positioning rod 232, elastic member 233, limiting plate 235, and cover plate 234. This structural arrangement not only improves the operational convenience and adaptability of the device, but also enhances the overall structural stability and reliability.

[0046] As some preferred embodiments, a positioning sleeve 236 is coaxially fixed on the inner top surface of the cover plate 234, and the distance between the positioning sleeve 236 and the inner bottom surface of the cylinder 231 is less than or equal to the distance between the top surface of the limit plate 235 and the bottom end of the positioning rod 232, and the elastic member 233 is located between the positioning sleeve 236 and the positioning rod 232.

[0047] With this arrangement, when the positioning rod 232 is lifted, when the positioning rod 232 moves upward and disengages from the positioning hole 10, and the limit plate 235 abuts against the bottom end of the positioning sleeve 236, the positioning rod 232 cannot continue to be pulled upward, thereby limiting the upward movement stroke of the positioning rod 232. On the one hand, it can avoid fatigue damage to the elastic member 233 caused by excessive pulling. On the other hand, it can avoid excessive upward movement of the positioning rod 232, resulting in the lower end of the positioning rod 232 being completely inserted into the cylinder 231. The lower end of the positioning rod 232 is not constrained, and the positioning rod 232 and the cylinder 231 are not coaxial, resulting in the lower end of the positioning rod 232 being unable to smoothly pass through the bottom end of the cylinder 231 during the resetting process, affecting the cooperation between the positioning rod 232 and the positioning hole 10.

[0048] A lifting portion 237 is fixedly provided on one end of the positioning rod 232 extending outward from the outer side of the cover plate 234. The positioning rod 232 can be easily lifted upward through the lifting portion 237, which is convenient for operation.

[0049] In order to prevent the first sleeve 21 or the second sleeve 31 from rotating relative to the lever 1 when adjusting the position on the lever 1, it is not convenient for the positioning rod 232 in the locking device to match the positioning hole 10. Figure 3 As shown, in this embodiment, a guide groove C is further provided on the outer peripheral surface of the first arm section 11 along its axial direction, and a guide portion D matching the guide groove C is provided on the inner side surfaces of the first sleeve 21 and the second sleeve 31 in the axial direction.

[0050] With this arrangement, through the cooperation of the guide portion D and the guide groove C, the first sleeve 21 and the second sleeve 31 can only slide along the axial direction of the lever 1, limiting the possibility of circumferential rotation of the sleeve relative to the lever 1, thereby facilitating the position adjustment of the sleeve on the lever 1.

[0051] Preferably, the mobile frame 22 in this embodiment includes a support frame 221 and a roller 222. The upper end of the support frame 221 is fixedly connected to the first sleeve 21, and the roller 222 is rotatably connected to the lower end of the support frame 221. The support frame 221 provides support for the force point of the lever 1, and the roller 222 allows the entire transfer tool to move after lifting the heavy object.

[0052] Preferably, the hanging member 32 is a chain hook or a clamping claw. Wherein, the chain hook can directly lift the heavy object, and the clamping claw can clamp the heavy object.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
