[0030] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0031] like Figure 1-Figure 2 As shown, an embodiment of the utility model provides a lifting fixture for lifting a fan pump 100 of an excavator. One end of the fan pump 100 is provided with a connecting flange 101 for connecting to the lifting fixture.

[0032] The lifting fixture comprises a clamping mainboard 1 and a pair of rotating clamping members 2 symmetrically arranged on the clamping mainboard 1, that is, the pair of rotating clamping members 2 includes two rotating clamping members 2, and the two rotating clamping members 2 are symmetrically distributed. The rotating clamping member 2 comprises a connecting portion 21 and a lifting portion 22 and a clamping portion 23 connected to both ends of the connecting portion 21. The connecting portion 21 is rotatably connected to the clamping mainboard 1, and the lifting portion 22 can be connected to the lifting equipment. When lifting the fan pump 100, the lifting fixture is first connected to the fan pump 100, that is, the clamping mainboard 1 is installed on the upper end surface of the connecting flange 101 of the fan pump 100, and the lifting equipment is started to lift the lifting portion 22. The clamping portion 23 rotates on the clamping mainboard 1 through the connecting portion 21, and can automatically abut the lower end surface of the connecting flange 101, and clamp the connecting flange 101 between the clamping portion 23 and the clamping mainboard 1. When two pairs of rotating clamping members 2 are provided, the two pairs of rotating clamping members 2 may be distributed in a cross pattern. Of course, three or more pairs of rotating clamping members 2 may also be provided, which will not be described in detail here.

[0033] The hoisting fixture can be used to lift the fan pump 100 by the hoisting equipment, avoiding manual handling, improving safety and production efficiency, and by rotating the clamping member 2 and the clamping mainboard 1, it is realized that when the hoisting equipment lifts the hoisting part 22, the clamping part 23 automatically moves toward the clamping mainboard 1 and clamps the connecting flange 101, making installation and use more convenient.

[0034] In order to prevent the fan pump 100 from sliding relative to the clamping mainboard 1 during the hoisting of the hoisting equipment, at least two positioning columns 11 are provided on the end face of the clamping mainboard 1 facing the fan pump 100, and positioning holes are provided at positions corresponding to the positioning columns 11 on the connecting flange 101. When the tooling fixture for hoisting is connected to the connecting flange 101, the clamping mainboard 1 abuts against the upper end face of the connecting flange 101, and the positioning columns 11 are plug-connected with the corresponding positioning holes. The plug-in connection between the positioning columns 11 and the positioning holes can prevent the fan pump 100 from moving along the radial direction of the positioning columns 11, thereby effectively preventing the fan pump 100 from falling. Of course, the positioning columns 11 and the positioning holes are provided in a one-to-one correspondence, and three, four or more positioning columns 11 can be provided respectively. The plurality of positioning columns 11 can be evenly distributed on the clamping mainboard 1, and the plurality of positioning holes can be evenly distributed on the connecting flange 101. The plurality of positioning columns 11 can be plug-matched with the plurality of positioning holes respectively.

[0035] The lifting fixture also includes a rotating shaft 3 corresponding to the rotating clamping member 2. The connecting portion 21 is rotatably arranged on the clamping main board 1 through the rotating shaft 3. The rotating shaft 3 is arranged on the clamping main board 1. The connecting portion 21 is rotatably arranged on the rotating shaft 3. The structure is simple and the rotating clamping member 2 is flexible to rotate.

[0036] In order to facilitate the installation of the rotating clamp 2 and the rotating shaft 3, an extension portion 12 is provided at the position corresponding to the rotating clamp 2 on the outer circumference of the clamping main board 1, and each extension portion 12 is provided with mounting portions 121 spaced apart along the axial direction of the rotating shaft 3. The rotating shaft 3 is provided on two corresponding mounting portions 121, and the connecting portion 21 of the rotating clamp 2 is rotatably provided on the rotating shaft 3 and is located between the two mounting portions 121. Specifically, the mounting portion 121 is provided with a mounting hole, and the rotating shaft 3 is passed through the mounting holes of the two corresponding mounting portions 121.

[0037] Furthermore, in order to prevent the rotating clamping member 2 from moving along the axial direction of the rotating shaft 3, a limiting notch 122 is opened on each extension portion 12, and the limiting notch 122 is located between the corresponding two mounting portions 121. The connecting portion 21 is rotatably arranged on the rotating shaft 3 and limited between the two limiting notches 122 to limit the rotating clamping member 2 from moving along the axial direction of the rotating shaft 3, thereby ensuring stability and improving safety at the same time.

[0038] In order to further improve the convenience of using the lifting fixture, refer to Figure 2An elastic member 4 is provided between the hoisting part 22 and the clamping mainboard 1. The elastic member 4 drives the hoisting part 22 to rotate away from the clamping mainboard 1 with the rotating shaft 3 as the axis, thereby driving the clamping part 23 to rotate toward the clamping mainboard 1. When the hoisting fixture is in use, after it is installed on the connecting flange 101 and before the hoisting equipment is connected to the hoisting part 22, the elastic member 4 enables the clamping part 23 to have a force to rotate toward the clamping mainboard 1, so that the clamping part 23 and the clamping mainboard 1 pre-clamp the connecting flange 101, so that when the hoisting equipment is installed and connected to the hoisting part 22, the hoisting fixture is pre-connected with the connecting flange 101, and the hoisting is more stable, so as to prevent the situation of loose clamping during hoisting.

[0039] A clamping block 231 for abutting the connecting flange 101 is provided at the end of the clamping portion 23. The connecting flange 101 is clamped between the clamping block 231 and the clamped main board 1. The width dimension of the clamping block 231 along the axial direction of the rotating shaft 3 is larger than the width dimension of the clamping portion 23 along the axial direction of the rotating shaft 3, so as to make the connection more secure.

[0040] In order to prevent the lifting fixture from damaging the appearance of the fan pump 100 when clamping it, protective pads are provided on the end face of the clamping block 231 facing the clamping main board 1 and the end face of the clamping main board 1 facing the clamping block 231. The protective pads can be selected as rubber pads or silicone pads, so that when the clamping block 231 and the clamping main board 1 clamp the connecting flange 101, the protective pads can provide effective protection for the connecting flange 101.

[0041] In order to facilitate the connection between the lifting device and the lifting part 22 , a lifting lock buckle 5 is provided on the lifting part 22 , and the lifting device is connected to the lifting lock buckle 5 .

[0042] Furthermore, the lifting lock buckle 5 includes a U-shaped buckle 51, a screw rod 52 and a lock nut. The screw rod 52 is passed through the lifting part 22 and the two side rods of the U-shaped buckle 51. The two side rods are respectively located on both sides of the lifting part 22 along the axial direction of the screw rod 52. The lock nut is screwed to the screw rod 52 to limit the two side rods between the lock nut and the nut of the screw rod 52. The lifting lock buckle 5 is simple and convenient to install, and the lifting is more convenient.

[0043] In this embodiment, the clamping mainboard 1 is further provided with a through hole 123 for avoiding the knob 102 of the fan pump 100 .

[0044] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here.
