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.

[0035] Example 1:

[0036] See also Figures 1 to 5 In an embodiment of the present invention, a block hoisting clamping tool includes a hollow square rod 1, a movable groove 7 is formed in the middle of the top surface of the hollow square rod 1, two through grooves 1 2 are formed on one side of the hollow square rod 1 and are symmetrically distributed about the middle of the hollow square rod 1, and two movable grooves 2 16 are formed on the bottom surface of the hollow square rod 1 and are symmetrically distributed about the middle of the hollow square rod 1;

[0037] Two square slide bars 5 are slidably mounted in the hollow square rod 1. The opposite ends of the two square slide bars 5 extend to the bottom of the movable groove 7. The top surfaces of the two square slide bars 5 are fixedly connected to a connecting assembly connected to the lifting equipment between the positions near the opposite ends. The connecting assembly is used to drive the two square slide bars 5 to slide away from each other when lowering, and to drive the two square slide bars 5 to slide close to each other during the lifting process.

[0038] The bottom surface of the square slide bar 5 is detachably fixedly connected with a clamping assembly 3, which includes a mounting plate 21. A through slot 3 22 is provided on the side of the mounting plate 21. An adjustment assembly is fixedly installed on the outer surface of the mounting plate 21. The output end of the adjustment assembly passes through the through slot 3 22 to the inner side of the mounting plate 21 and is fixedly connected with a resistance assembly.

[0039] Among them, a plurality of slots 18 are arranged in an array along the longitudinal midline direction of the movable slot 2 16 on the bottom surface of the square slide bar 5 , and a threaded hole 6 is arranged on one side of the slot 18 close to the through slot 1 2 .

[0040] Among them, the middle position of the top surface of the mounting plate 1 21 is fixedly connected with a clamping rod 19, and a slot is opened on the side of the clamping rod 19 near the top position;

[0041] When the mounting plate 1 21 and the upper square slide bar 5 are in a fixed connection state, the top end of the clamping rod 19 is slidably inserted into a clamping slot 18, and a bolt 17 is threadedly installed in the threaded hole 6 of the clamping slot 18. The front end of the bolt 17 is slidably inserted into the slot on the side of the clamping rod 19;

[0042] An oblique reinforcement rod 20 is fixedly connected between the two ends of the top surface of the mounting plate 21 and the side surfaces corresponding to the clamping rod 19.

[0043] The adjustment assembly includes mounting seats 26 fixedly mounted at both ends of the outer side of the mounting plate 1 21, a bidirectional screw rod 27 is rotatably mounted between the two mounting seats 26, and two guide rods 28 symmetrically distributed about the bidirectional screw rod 27 are fixedly connected between the two mounting seats 26;

[0044] The outer periphery of the bidirectional screw rod 27 is threadedly mounted with two slides 29 symmetrically distributed about the middle position of the bidirectional screw rod 27, and the slides 29 are slidably connected to the two guide rods 28; a knob 30 is fixedly mounted at the middle position of the outer periphery of the bidirectional screw rod 27;

[0045] A connecting block 23 is fixedly connected to the center position of one side of the slide 29 close to the mounting plate 1 21. The end of the connecting block 23 away from the slide 29 passes through the through slot 3 22. The top and bottom surfaces of the connecting block 23 are in sliding contact with the top and bottom surfaces of the through slot 3 22, and the end of the connecting block 23 away from the slide 29 is flush with the inner side surface of the mounting plate 1 21.

[0046] The abutment assembly includes two second mounting plates 24, which are respectively fixedly connected to one end of the two connecting blocks 23 away from the slide 29, and the side of the second mounting plate 24 close to the connecting block 23 is in sliding contact with the inner side surface of the first mounting plate 21;

[0047] A friction pad 25 is fixedly mounted on a side of the second mounting plate 24 away from the connecting block 23 .

[0048] In the adjustment assembly, by rotating the bidirectional screw rod 27 through the knob 30, the two slides 29 can be driven to slide closer or away at the same time, thereby driving the two mounting plates 24 to move closer or away through the two connecting blocks 23, thereby achieving the purpose of adjusting the distance between the two friction pads 25.

[0049] The connecting assembly includes a U-shaped mounting seat 1 8 and a U-shaped mounting seat 2 9. The top surfaces of the two square slide bars 5 are fixedly mounted with a U-shaped mounting seat 1 8 at positions near the opposite ends. A pin 12 is fixedly mounted in the U-shaped mounting seat 1 8. A collar 13 is rotatably sleeved around the periphery of the pin 12. The collar 13 is fixedly connected to the periphery of the connecting rod 11. The end of the connecting rod 11 away from the collar 13 is fixedly connected to the collar 2 15.

[0050] The U-shaped mounting seat 29 is located directly above the hollow square rod 1. A pin 24 is fixedly mounted in the U-shaped mounting seat 29. The collars 25 at the ends of the two connecting rods 11 are rotatably sleeved on the periphery of the pin 24.

[0051] The center position of the top surface of the U-shaped mounting seat 2 9 is rotatably connected to a suspension rod 10 , and the top end of the suspension rod 10 is fixedly connected to a suspension ring 4 .

[0052] During the lowering process, after the bottom surface of the hollow square rod 1 contacts the top surface of the additional building block, the angle between the two connecting rods 11 gradually increases until the two U-shaped mounting seats 8 are squeezed into contact with the two ends of the movable groove 7. At this time, the two groups of clamping components 3 are in a loose state, and the two groups of clamping components 3 are located on both sides of the additional building block. Then the device is lifted. During the process, the angle between the two connecting rods 11 gradually decreases until the two groups of clamping components 3 are squeezed into contact with the additional building block (when the clamping components 3 are in contact with the additional building block, there is a gap between the two square slide bars 5, and the angle between the two connecting rods 11 is an acute angle). At this time, the clamping of the additional building block is completed, thereby realizing the lifting action of the additional building block.

[0053] When the utility model is in use:

[0054] When hoisting the additional block, first adjust the working distance between the two sets of clamping assemblies 3 according to the width of the additional block. Specifically, select a suitable slot 18 according to the width of the additional block, then insert the top of the clamping rod 19 into the slot 18, and then fix the clamping rod 19 in the slot 18 by using bolts 17 to match the slots on the side of the clamping rod 19.

[0055] Then, the distance between the two friction pads 25 is adjusted according to the length of the additional block. Specifically, when the length of the additional block is greater than the length of the mounting plate 1 21, the two mounting plates 24 are adjusted to the two end positions of the mounting plate 1 21 through the adjustment assembly. At this time, the distance between the two friction pads 25 is maximized, and the distance between the contact points of the two friction pads 25 and the side of the additional block is maintained at the maximum. At this time, when the device body is manually placed in the middle position in the length direction of the additional block, the deviation between the midpoint of the device and the midpoint of the additional block can be effectively reduced, thereby reducing the tilt amplitude of the additional block during the hoisting process, and ensuring the stability of the hoisting process.

[0056] When the length of the additional block is less than the mounting plate 21, the distance between the two friction pads 25 is set to the length of the additional block by adjusting the assembly. At this time, when lifting, the friction pad 25 at one end is aligned with the end of the additional block, and the other friction pad 25 is also aligned with the other end of the additional block, so that the device body and the additional block can quickly be in a higher centered alignment state, thereby ensuring the stability of the additional block during the lifting process.

[0057] Therefore, in the present invention, the clamping width can be adjusted within a certain range according to the width value of the additional building block through the coordinated arrangement of the hollow square rod 1, the square slide rod 5 and the clamping assembly 3, thereby improving the practicality of the device; in the clamping assembly 3, the adjustment assembly, the mounting plate 21 and the resistance assembly are coordinated to make the contact points between the clamping assembly 3 and the additional building block two, which can disperse the load of the additional building block, reduce the tilt and deformation caused by concentrated force, and improve the stability of the lifting process, and the distance between the contact points is adjustable, so that the operator can adjust the position of the clamping point in time according to the size of the additional building block to ensure the optimal force state, better control the lifting posture of the additional building block, and avoid potential dangers caused by tilting.

[0058] Example 2:

[0059] On the basis of Example 1, balls are evenly embedded on the inner wall of the hollow square rod 1. Through the setting of the balls, the square slide rod 5 and the hollow square rod 1 are in rolling contact, which reduces the friction between the square slide rod 5 and the hollow square rod 1 and improves the smoothness of the sliding movement between the two square slide rods 5 away from or close to each other, thereby improving the stability of driving the two groups of clamping components 3 to loosen or clamp.

[0060] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
