Description

Technical Field

[0001] This application relates to the field of port loading and unloading equipment technology, and in particular to a multi-functional tool for maintenance of lifting equipment. Background Technology

[0002] Spreading gear is a key component of quay cranes in container handling equipment at the port, and it is also a special tool for loading and unloading containers.

[0003] Generally, after a certain period of operation, the spare lifting equipment is replaced with the equipment awaiting maintenance, and the replaced equipment is transported to the maintenance site for upkeep. During disassembly, the operator typically comes into direct contact with the moving lifting frame, manually aligning the lifting frame's locking head with the lifting equipment's locking hole for replacement. This process presents a safety hazard of human-machine interaction. Specifically, the coordination between the lifting frame and the equipment requires manual intervention from the operator, leading to situations where human-machine interaction occurs and posing significant safety risks. Utility Model Content

[0004] To effectively ensure a safe distance between the technician and the lifting frame and to protect the operator's life, this application provides a multi-functional tool for lifting equipment maintenance.

[0005] This application provides a multi-functional tool for repairing lifting devices, which adopts the following technical solution:

[0006] A multi-functional tool for repairing lifting devices includes a support rod and an arc-shaped hook, with the end of the support rod and the end of the hook fixedly connected.

[0007] By adopting the above technical solution, on the one hand, because the support rod has a certain length, it can ensure a safe distance between the operator and the moving machinery during use, reducing the risk of personnel injury during the descent of the gantry; the hook setting can assist the operator in remotely tightening the quick plug, reducing the phenomenon of the quick plug falling off due to mechanical vibration; on the other hand, the tool is easy to carry and can be used independently, improving the operator's work efficiency.

[0008] Optionally, a barb is fixedly connected to the end of the hook away from the support rod, and the barb and the hook are set at a certain angle.

[0009] By adopting the above technical solution, the barb can help the operator hook the gantry, enabling manual intervention to make the gantry and lifting tool work together, thus improving the multi-functional applicability of the tool.

[0010] Optionally, an abutment block is fixedly connected to the end of the support rod away from the hook, and the abutment block and the support rod are arranged perpendicular to each other.

[0011] By adopting the above technical solution, the setting of the abutment block can assist the operator in lifting the lifting tool's support rod, facilitating the inspection of relevant parts during lifting tool maintenance, and improving the multi-functional applicability of the tool under the premise of safety and labor saving.

[0012] Optionally, the sidewall of the support rod is provided with graduations along the length of the support rod.

[0013] By adopting the above technical solution and setting the scale, the operator can help determine whether the limit sensing distance meets the sensing standard, thereby improving the multi-functional applicability of the tool under the premise of safety and labor saving.

[0014] Optionally, the support rod is provided with a grip handle, the circumferential sidewall of the grip handle is provided with a groove for the operator's fingers to place, and the grip handle is provided with a through hole for the support rod to pass through.

[0015] By adopting the above technical solution and the design of the handle, when the operator needs to rotate the support rod while tightening the quick connector, the operator's hand can grip the handle to rotate the support rod, reducing wear on the palm of the support rod and improving the rotation efficiency of the support rod.

[0016] Optionally, the support rod is provided with a plurality of mounting holes evenly spaced along its length, the circumferential sidewall of the grip handle is provided with a limiting hole that communicates with the through hole, the inner sidewall of the through hole is provided with a positioning groove that communicates with the through hole and is coaxially arranged with the limiting hole, and the grip handle is provided with a pin located in the groove, the pin being sequentially engaged in the limiting hole, the mounting hole and the positioning groove.

[0017] By adopting the above technical solution, the mounting holes and the setting of the pivot pins allow the entire grip handle to move along the length of the support rod, thereby adjusting the position of the grip handle on the support rod and adjusting the force angle when the operator grips and rotates the grip handle, thus improving the operator's rotation efficiency.

[0018] Optionally, a pressure spring located in the positioning groove is fixedly connected to the grip handle. One end of the pressure spring away from the bottom wall of the positioning groove abuts against the shaft pin. A sliding groove is provided on the inner circumferential side wall of the limiting hole. A limiting block embedded in and sliding in the sliding groove is fixedly connected to the shaft pin.

[0019] By adopting the above technical solution, the pressure spring can push the pin out of the positioning groove and mounting hole, making it easy for the rotating handle to slide on the support rod. When it slides to the appropriate position, hold the grip handle and push the pin into the positioning groove. While fixing the grip handle and the support rod, rotate the support rod, thereby driving the hook to tighten the quick plug.

[0020] Optionally, a reinforcing rib is fixedly connected to the support rod, and one end of the reinforcing rib is fixedly connected to the hook.

[0021] By adopting the above technical solution and adding reinforcing ribs, the structural strength of the connection between the support rod and the hook can be increased, thereby reducing the possibility of breakage at the connection between the support rod and the hook when the operator applies force.

[0022] Optionally, the support rod, the hook, the abutment block, and the barb are all integrally formed.

[0023] By adopting the above technical solution and setting it up as a whole, the structural strength and stability of the entire support rod, hook, abutment block and barb can be increased.

[0024] Optionally, the grip handle is provided with anti-slip texture.

[0025] By adopting the above technical solution, the anti-slip texture can increase the friction between the operator's palm and the handle, making it easier for the staff to operate the support rod.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. On the one hand, it can ensure that the operator maintains a safe distance from the moving machinery, reducing the risk of personnel injury during the descent of the gantry; on the other hand, it can assist the operator in remotely tightening the quick-connect plugs, reducing the phenomenon of quick-connect plugs falling off due to mechanical vibration.

[0028] 2. The barb design helps the operator hook the lifting frame, enabling manual intervention to coordinate the lifting frame and lifting tools, thus improving the tool's versatility.

[0029] 3. The integrated design increases the structural strength and stability of the entire support rod, hook, abutment block, and barb. Attached Figure Description

[0034] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0035] This application discloses a multi-functional tool for repairing lifting devices. (Refer to...) Figure 1 A multi-functional tool for lifting equipment maintenance includes a support rod 2, an arc-shaped hook 1, a barb 3, and a stop block 4. One end of the hook 1 is integrally attached to the end of the support rod 2, facilitating remote tightening of the quick-connect plug by the operator. One end of the barb 3 is integrally attached to the end of the hook 1 furthest from the support rod 2, and the barb 3 is inclined towards the support rod 2 at a certain angle to the hook 1, facilitating the operator to hook the lifting frame. The stop block 4 is integrally attached to the end of the support rod 2 furthest from the hook 1 and is perpendicular to the support rod 2, assisting the operator in lifting the lifting frame.

[0036] Reference Figure 1 The support rod 2 has scales 21 arranged on its side wall, which are set along the length of the support rod 2. The overall thickness of the support rod 2 and the abutment block 4 is 8mm, which facilitates the operator to judge whether the limit sensing distance meets the standard. The support rod 2 is integrally provided with two reinforcing ribs 22, which are located on opposite side walls at the connection between the support rod 2 and the hook 1, thereby increasing the structural strength between the support rod 2 and the hook 1.

[0037] Reference Figure 1 and Figure 2 A grip handle 5 is installed on the support rod 2. A through hole 51 is provided in the grip handle 5 for the support rod 2 to pass through. Several grooves 52 are evenly arranged on the outer periphery of the grip handle 5. When the operator grips the grip handle 5, he can place his fingers in the grooves 52, which makes it easier for the operator to apply force to the support rod 2.

[0038] Reference Figure 2The support rod 2 has several mounting holes 23 penetrating the opposite sidewalls. These mounting holes 23 are all located above the scale 21 and are evenly spaced along the length of the support rod 2. When the handle 5 is fitted onto the support rod 2, part of the support rod 2 is located within the through hole 51, and the mounting holes 23 and the through hole 51 are interconnected. The outer circumferential sidewall of the handle 5 has a limiting hole 53 communicating with the through hole 51. The inner sidewall of the through hole 51 has a positioning groove 54 coaxially arranged with the limiting hole 53. A pin 55 is installed on the handle 5. The pin 55 passes through the limiting hole 53 and the mounting hole 23 sequentially and is then embedded in the positioning groove 54, thereby fixing the handle 5 and the support rod 2. In this embodiment, the operator can align the mounting hole 23 and the limiting hole 53 by referring to the scale 21; the pin 55 is a round shaft and there are two of them.

[0039] Reference Figure 2 A pressure spring 56 is fixedly connected to the bottom wall of the positioning groove 54. The end of the pressure spring 56 away from the bottom of the positioning groove 54 abuts against the shaft pin 55. The pressure spring 56 drives the end of the shaft pin 55 to disengage from the mounting hole 23 according to its own elastic force, so that the handle 5 can move on the support rod 2. A limiting block 57 is fixedly connected to the outer peripheral side wall of the shaft pin 55. A sliding groove 58 is provided on the inner side wall of the limiting hole 53 for the limiting block 57 to be inserted and slid, thereby reducing the possibility of the shaft pin 55 disengaging from the limiting hole 53.

[0040] Reference Figure 2 and Figure 3 The outer circumference of the handle 5 is provided with several anti-slip textures 59 to increase the friction between the operator's palm and the handle 5. The limiting hole 53 is located in the groove 52 of the handle 5. When the end of the pin 55 away from the positioning groove 54 extends out of the groove 52, the other end of the pin 55 disengages from the mounting hole 23. At this time, the handle 5 can slide on the support rod 2. When the operator holds the handle 5, the operator's fingers push the pin 55, so that the end of the pin 55 near the positioning groove 54 passes through the mounting hole 23 and is embedded in the positioning groove 54. When the operator moves the support rod 2, the handle 5 is fixed on the support rod 2.

[0041] The implementation principle of a multi-functional tool for lifting equipment maintenance according to the embodiments of this application is as follows: When the operator uses the tool, he slides the handle 5 to an appropriate position according to his own habits, and then compares it with the scale 21 so that the mounting hole 23, the limiting hole 53 and the positioning groove 54 are all aligned. The operator reaches out and holds the handle 5. At this time, the shaft pin 55 is sequentially embedded in the limiting hole 53, the mounting hole 23 and the positioning groove 54. Then, he moves the support rod 2; or he holds the handle 5 and uses the barb 3 to hook the lifting frame; or he can use the end of the support rod 2 with the abutment block 4 to push up the box rod.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
