[0024] In order to make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0025] In order to solve the technical problem of how to horizontally hoist parts into the installation position, the present utility model provides a clamping type lifting tool, which can realize horizontally hoisting parts into the installation position.

[0026] It should be noted that the clamping type lifting tool described in the present utility model is used for but not limited to hoisting gear parts in the assembly of large reducers. For the convenience of description, in the present utility model, only the case where the clamping type lifting tool is applied to hoisting gear parts in the assembly of large reducers is taken as an example for description, and the principle of the clamping type lifting tool applied to other types of equipment is essentially the same as that of hoisting gear parts in the assembly of large reducers, which will not be elaborated one by one here.

[0027] Please refer to Figure 1 , Figure 1This is a three-dimensional structure diagram of a clamping type sling in an embodiment of the present utility model. The clamping type sling includes a hoisting part 1 and a clamping component 2. The hoisting part 1 includes a hoisting frame 11, a fixed lifting lug 12, a movable lifting lug 13 and a sliding component 14. The fixed lifting lug 12 is fixed at the top of the hoisting frame 11. The top of the hoisting frame 11 is in the shape of a crossbeam. The fixed lifting lug 12 is located at the left end of the crossbeam. The movable lifting lug 13 starts from the right end of the crossbeam and can move towards the left end. Specifically, the movable lifting lug 13 is arranged on the top of the hoisting frame 11 through the sliding component 14 and is opposite to the fixed lifting lug 12. The sliding component 14 is used to move and adjust the distance between the movable lifting lug 13 and the fixed lifting lug 12. Driven by the sliding component 14, the fixed lifting lug 12 is driven to move horizontally left and right along the length direction of the crossbeam, so as to achieve the function of adjusting the distance. The purpose is that when hoisting parts, moving the movable lifting lug 13 can adjust the hoisting to the balanced position. The clamping component 2 is arranged at the bottom of the hoisting frame 11 and is used to clamp the parts in an openable and closable manner. Its clamping position is at the edge position of the part, and there is also a certain interval between the hoisting frame 11 and the clamping position. Therefore, with this structural arrangement, there is enough space to hoist the gear part 5 and horizontally move it into the installation position without interfering with the assembly position.

[0028] In one of the embodiments, please refer to Figure 1 , in order to horizontally move and adjust the movable lifting lug 13, the sliding component 14 includes a linear driving member 141 and a connecting rod 142. A strip-shaped hole 101 is opened at the top of the hoisting frame 11. The length direction of the strip-shaped hole 101 is parallel to the length direction of the crossbeam and is used for guiding. The connecting rod 142 is arranged at the top of the movable end of the linear driving member 141, penetrates through the strip-shaped hole 101 and is slidably connected with it. Through the relative sliding of the connecting rod 142 and the strip-shaped hole 101, the horizontal movement is guided to improve the stability of the horizontal movement adjustment. Among them, the movable lifting lug 13 is arranged at the top end of the connecting rod 142, and the bottom width of the lifting lug 13 is greater than the hole width of the strip-shaped hole 101 to form a limit.

[0029] It can be understood that the linear driving member 141 can adopt a ball screw guide pair driven by a motor, or a hydraulic push rod or other mechanisms with telescopic functions, as long as the purpose of horizontally driving the connecting rod 142 can be achieved. They are all existing mature mechanisms or equipment and are not uniquely limited here.

[0030] Furthermore, please refer to Figure 1 , in order to improve the sliding smoothness of the linear driving member 141 during hoisting and avoid excessive sliding resistance, a pair of rollers 102 are arranged at the movable end of the linear driving member 141. The rollers 102 are slidably connected with the bottom of the hoisting frame 11. During hoisting, the rollers 102 serve as force-bearing support points to share the force, which can reduce the frictional resistance and improve the smoothness of the telescopic control.

[0031] In one embodiment, please refer to Figure 1 and Figure 3 , in order to assist in adjusting to the horizontal during hoisting, the clamping type lifting tool further includes a horizontal control assembly 3. The horizontal control assembly 3 includes a horizontal sensor 31. The horizontal sensor 31 is arranged on the lifting frame 11. Among them, the horizontal sensor 31 can adopt a bubble level, an electronic inclinometer or a wireless horizontal sensor. The above devices can effectively monitor whether the lifting tool is in a horizontal state, and correspondingly adjust the position of the moving lifting lug 13 according to whether it is in a horizontal state until it is adjusted to the horizontal position.

[0032] Furthermore, for the purpose of automatic adjustment, please refer to Figure 3 , the horizontal control assembly 3 further includes a controller 32. The horizontal sensor 31 and the linear driving member 141 are both electrically connected to the controller 32. The controller 32 controls the expansion and contraction of the linear driving member 141 according to the electrical signal of the inclination angle of the lifting frame 11 monitored by the horizontal sensor 31. Among them, the horizontal sensor 31 adopts an electronic inclinometer. The electronic inclinometer monitors the inclination angle of the lifting tool in real time and converts this information into an electrical signal for output. The controller 32 can adopt a programmable logic controller (PLC), receive the electrical signal, and control the movable end of the linear driving member 141 to move left or right according to the electrical signal until it is horizontal.

[0033] In one embodiment, please refer to Figure 1 and Figure 2 , in order to clamp the gear part 5, the clamping assembly 2 includes a frame body 21, an extension frame 22, a screw 23, an upper pressing block 24 and a lower pressing block 25. The frame body 21 is detachably connected to the bottom of the lifting frame 11. An extension frame 22 is arranged on one side of the frame body 21. The frame body 21 and the extension frame 22 form a horizontally placed U shape. A screw hole is opened at the top of the extension frame 22. The screw 23 is threadedly connected in the screw hole. The screw 23 can be adjusted up and down by rotating it. The upper pressing block 24 is arranged at the bottom end of the screw 23. The lower pressing block 25 is arranged at the bottom of the frame body 21 and is opposite to the upper pressing block 24. The upper pressing block 24 and the lower pressing block 25 are respectively used to abut against the top and bottom of the part. Place the lower pressing block 25 at the bottom of the gear part 5 and abut against its bottom, and then rotate the screw 23 to move the upper pressing block 24 downward until it abuts against the top of the gear part 5, so as to cooperate with the lower pressing block 25 to clamp the gear part 5.

[0034] Furthermore, in order to facilitate the rotation of the screw 23, a handle 2301 is arranged at the top end of the screw 23.

[0035] Furthermore, for anti-slip during clamping, anti-slip pads are arranged on the opposite sides of the upper pressing block 24 and the lower pressing block 25.

[0036] In one of the embodiments, please refer to Figure 1 and Figure 2 , for the convenience of assembling the spreader, a slot 103 is opened at the bottom of the lifting frame 11, a plug 201 is arranged at the top of the frame body 21, the plug 201 is inserted into the slot 103, and a locking member 4 is arranged between the plug 201 and the slot 103 for locking the insertion. By unlocking the locking member 4, the plug 201 can be disengaged from the slot 103, which is convenient for the assembly and disassembly of the clamping assembly 2 and the lifting part 1.

[0037] Specifically, the locking member 4 includes a plurality of groups of bolts 41 and nuts 42. A plurality of through holes 401 are correspondingly opened on the plug 201 and the slot 103. One end of the bolt 41 penetrates through the corresponding through hole 401 and is threadedly connected to the nut 42. Specifically, there are two bolts 41 and two nuts 42. One bolt 41 penetrates through the corresponding through holes 401 on the plug 201 and the slot 103 respectively, and its head and the nut 42 are respectively abutted against the front side and the rear side of the lifting frame 11 to form the connection and locking of the lifting frame 11 and the frame body 21. Conversely, removing the bolt 41 can unlock the locking.

[0038] For a better understanding of the present invention, the following combines Figures 1 to 3 to elaborate on the technical solution of the present invention in detail: Move the lower pressing block 25 to the position where it can be attached to the bottom edge of the gear part 5. Grasp the handle 2301 and rotate the screw rod 23 to lower the upper pressing block 24 to form a clamp on the gear part 5 together with the lower pressing block 25. Then, through the lifting device, lift the entire lifting part 1 and the clamping assembly connected to the lifting part 1 to lift the gear part 5. Then, horizontally adjust the position of the moving lifting lug 13 through the linear driving member 141 until the entire lifting frame 11 is horizontal, that is, the gear part 5 is horizontal, and then perform the lifting and moving to horizontally move the gear part 5 into the position where it needs to be assembled.
