[0001] This utility model relates to the technical field of automated equipment, and in particular to a differential lifting fixture. Background Technology

[0002] Lifting tools are tools used for lifting and moving goods. Some are designed for specific lifting tasks or objects and are widely used in many fields. Existing lifting tools can be used with gantry cranes, but some have relatively complex structures, including a series of pneumatic pipelines. Their use is limited by the scene or scope, making them inconvenient to operate and with low adaptability. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a differential lifting tooling with a purely mechanical structure. Compared with pneumatic clamping tools, it is not limited by the layout of pneumatic pipelines, has a wider range of applications, and can effectively reduce the difficulty of manual loading and improve lifting efficiency.

[0004] To solve the above-mentioned technical problems, the present invention provides a differential lifting fixture, which is used in conjunction with a KBK gantry crane for material loading during the assembly process. It includes: a tensioning housing, a gripper travel limiting block disposed inside the tensioning housing, a first gripper slidably connected to the gripper travel limiting block, a second gripper, and a lever connected to the gripper travel limiting block with one end extending outside the tensioning housing. A travel groove is formed along the circumferential direction on the side wall of the tensioning housing for the lever to slide back and forth. Below the travel groove is a connection to the first gripper... The first and second grippers are connected by a sliding groove. The gripper travel limiting block has two sets of through arc-shaped limiting grooves along the axial direction. The top of the first and second grippers are respectively provided with a first positioning post and a second positioning post. The first and second positioning posts are restricted in the corresponding arc-shaped limiting grooves. Pushing the lever to move back and forth in the travel groove can drive the first and second positioning posts to move in the corresponding arc-shaped limiting grooves, thereby driving the first and second grippers to move in the sliding groove to move towards each other or away from each other.

[0005] In an embodiment of this utility model, an anti-drop pin is also included. The tension cover has positioning holes with relatively aligned positions on the upper and lower end faces of the travel groove. The anti-drop pin is inserted into the two sets of positioning holes to restrict the movement of the lever in the travel groove.

[0006] In an embodiment of this utility model, the two sets of arc-shaped limiting grooves are arranged opposite to each other and have an involute structure.

[0007] In an embodiment of this utility model, the top ends of the first gripper and the second gripper are provided with walking protrusions, which are slidably disposed in the sliding groove.

[0008] In an embodiment of this utility model, the cross-section of the walking protrusion is a "T"-shaped structure that cooperates with the sliding groove.

[0009] In an embodiment of this utility model, urethane pads are attached to the gripping ends of the first and second grippers.

[0010] The beneficial effects of this utility model are as follows: This differential lifting fixture has a simple, purely mechanical structure, without any constraints such as supporting pipelines and cables. Compared with pneumatic clamping tools, it is not limited by the layout of pneumatic pipelines, and has a wider range of applications. It has anti-drop pins, no risk of falling during movement, and a high safety factor. The clamping and opening actions of the lifting fixture can be completed by pushing the lever back and forth in the travel groove with one hand. The operation is convenient and quick, which can effectively reduce the difficulty of manual loading and improve lifting efficiency. Attached Figure Description

Detailed Implementation

[0016] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] Please see Figure 1-3This utility model discloses a differential lifting fixture, used in conjunction with a KBK gantry crane for material loading during assembly. It includes: a tensioning housing 1, a gripper travel limiting block 2 disposed inside the tensioning housing, a first gripper 3 and a second gripper 4 slidably connected to the gripper travel limiting block, and a lever 5 with one end connected to the gripper travel limiting block and the other end extending outside the tensioning housing. The tensioning housing has a circumferentially circumferentially formed travel groove 11 for the lever to slide back and forth. In this embodiment, the travel groove... The groove has an arc-shaped structure and its circumference is 1 / 3 to 1 / 2 of the circumference of the entire tensioning cover. Inside the tensioning cover, below the walking groove, there is a linear sliding groove 12 that cooperates with and slides with the first and second grippers. The gripper walking limit block has two sets of through arc-shaped limit grooves 21 along the axial direction. The top of the first and second grippers is respectively provided with a first positioning post 6 and a second positioning post 7 with the same structure. The first and second positioning posts are restricted to be inserted into the corresponding arc-shaped limit grooves.

[0018] Furthermore, the top of the tensioning cover is equipped with an installation shaft, which is connected to the conventional technology of KBK overhead cranes via fasteners. The operator moves the lifting tool and inserts the first and second jaws into the inner hole of the differential. The operator manually pushes the lever to move to the front end in the travel groove. The jaw travel limit block rotates accordingly, which can drive the first and second positioning pins to move in the corresponding arc-shaped limit grooves, thereby driving the first and second jaws to move towards each other in the sliding groove to clamp the differential.

[0019] Furthermore, it also includes anti-drop pins 8. Positioning holes 13 with relatively aligned positions are respectively provided on the upper and lower end faces of the travel groove on the tensioning cover. The positioning holes are opened at the position closest to the front end of the travel groove. When the lever is manually pushed to the front end in the travel groove, and the first and second grippers move towards each other to clamp the differential, the anti-drop pin is inserted into the two sets of positioning holes to restrict the movement of the lever in the travel groove, forming a safety protection. This ensures that the first and second grippers will not shift or open during the hoisting and moving process, and there is no risk of falling during the movement. It has a high safety factor, is convenient and safe to operate, and can be operated with one hand to complete the clamping and opening actions of the lifting device.

[0020] Furthermore, the two sets of arc-shaped limiting grooves are arranged opposite each other and have an involute linear structure. The top of the first and second grippers is integrally formed with a walking protrusion 9. The cross-section of the walking protrusion is a "T"-shaped structure that cooperates with the sliding groove. The walking protrusion is slidably disposed in the sliding groove. The bottom ends of the first positioning post 6 and the second positioning post 7 are connected to the top of the corresponding walking protrusion. When the lever is manually pushed to move in the walking groove, the first and second positioning posts are restricted to slide in the corresponding arc-shaped limiting groove, thereby driving the first and second grippers to move in the linear sliding groove, so as to release the differential with opposite movements or clamp the differential with relative movements.

[0021] Furthermore, urethane pads are attached to the gripping ends of the first and second jaws to ensure stable clamping without scratching the differential product.

[0022] Mechanism operation process:

[0023] 1. The operator moves the lifting tool and inserts the first and second jaws into the inner hole of the differential;

[0024] 2. Manually push the lever to move it to the front end in the travel groove. The gripper travel limit block rotates, which can drive the first positioning post and the second positioning post to move in the corresponding arc-shaped limit groove.

[0025] 3. The first positioning post and the second positioning post slide along the involute arc-shaped limiting groove, driving the first gripper and the second gripper to move towards each other in the sliding groove to clamp the differential.

[0026] 4. After the first and second grippers clamp the differential, insert the anti-drop pins into the two sets of positioning holes to restrict the movement of the lever in the travel groove, thus forming a safety protection.

[0027] 5. After the operator moves the lifting tool to place the differential in the designated position, pull up the anti-drop pin to leave the positioning hole, and push the lever to the rear end of the travel slot. The first and second grippers will release, releasing the clamped differential.

[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
