Description

Technical Field

[0001] This utility model relates to the field of stainless steel pipe hoisting and conveying technology, specifically a stainless steel pipe clamping and conveying robot. Background Technology

[0002] Large-diameter steel pipes generally refer to steel pipes with a specification of 325mm or more. Due to their large weight and volume, large-diameter steel pipes are usually hoisted and transferred by gantry cranes during factory processing. During hoisting, hooks are used to hook the open edges of both ends of the large-diameter steel pipe. The hooks are connected to the gantry crane hooks by steel wires. In this hoisting method, the contact area between the hooks and the steel pipe is small, which poses a safety hazard of hook detachment. Based on this, a stainless steel pipe clamping and conveying robot is provided. Utility Model Content

[0003] The purpose of this utility model is to provide a stainless steel pipe clamping and conveying robot to solve the problems mentioned above.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a stainless steel pipe clamping and conveying robot, comprising a clamping and hoisting assembly for hooking and hanging operations on the edges of both ends of the steel pipe, wherein the clamping and hoisting assembly comprises a hooking unit and a clamping unit;

[0005] The hook unit is used for hooking and hoisting operations with the edges of both ends of the steel pipe;

[0006] The clamping unit utilizes lifting force to clamp the hook unit and the steel pipe.

[0007] The hook unit includes a side-tilted concave hook, a flipping groove, a first positioning hook groove, and a steel wire sling.

[0008] The side-inverted concave hook is sleeved on the outer edges of both ends of the steel pipe, and the bottom horizontal part of the side-inverted concave hook is in contact with the upper surface of the inner wall of the steel pipe, for hooking the steel pipe.

[0009] The flip groove is opened on the lower surface of the horizontal part of the top of the side-inverted concave hook, and the first positioning groove is opened on the upper surface of the flip groove and is distributed at one end of the flip groove near the vertical part of the side-inverted concave hook.

[0010] The wire sling is sleeved inside the first positioning slot and the other end of the wire sling is hooked onto the gantry crane hook, used for lifting or lowering the side-inverted concave hook.

[0011] As a further improvement of this utility model: the clamping unit includes a 7-shaped flipping arm, an arc-shaped pressure plate, and a second positioning slot;

[0012] The 7-shaped flip arm is rotatably connected to the inner side of the flip groove away from the first positioning slot. The vertical part of the 7-shaped flip arm extends to the lower part of the horizontal part of the top of the side-inverted concave hook and is fixedly connected to the arc-shaped pressure plate. The second positioning slot is opened on the lower surface of the horizontal part of the 7-shaped flip arm.

[0013] The steel wire sling is moved and attached to the inside of the second positioning slot to provide upward pulling force to the horizontal part of the 7-shaped flip arm, so as to make the arc-shaped pressure plate flip down and press against the outer surface of the steel pipe, thereby achieving a tight press between the horizontal part of the bottom of the side-inverted concave hook and the steel pipe.

[0014] As a further improvement of this utility model: multiple second positioning slots are evenly arranged in the horizontal direction along the transverse part of the 7-shaped flip arm.

[0015] As a further improvement of this utility model, the weight of the horizontal part of the 7-shaped flip arm is greater than the sum of the weight of the vertical part of the 7-shaped flip arm and the weight of the arc-shaped pressure plate.

[0016] As a further improvement of this utility model: an arc-shaped baffle is fixed to the top horizontal part of the side-inverted concave hook below the flipping groove. The arc-shaped baffle is used to limit the downward flipping of the horizontal part of the 7-shaped flipping arm.

[0017] The connection position between the arc-shaped baffle and the side-inverted concave hook is far away from the first positioning groove, and the top of the arc-shaped baffle near the first positioning groove does not contact the side-inverted concave hook.

[0018] As a further embodiment of this utility model: when the arc-shaped pressure plate is in its lowest position, the distance between the lower surface of the arc-shaped pressure plate and the upper surface of the horizontal part of the bottom of the side-inverted concave hook is matched with the wall thickness of the steel pipe, and the lower surface of the arc-shaped pressure plate is covered with a layer of rubber.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] By setting up a clamping and lifting assembly, the assembly can clamp the edge of the steel pipe during the lifting operation. Compared with the traditional hook structure, it has a larger contact area and a more stable hook state, effectively preventing the hook from coming off and further improving the safety of transferring large-diameter steel pipes.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 In this embodiment of the utility model, a stainless steel pipe clamping and conveying robot includes a clamping and hoisting assembly 2 for hooking and hanging operations on the edges of both ends of a steel pipe 1. The clamping and hoisting assembly 2 includes a hooking unit and a clamping unit.

[0029] The hook unit is used for hooking and hoisting operations with the edges of both ends of the steel pipe 1;

[0030] The clamping unit uses the lifting force to clamp the hook unit and the steel pipe 1.

[0031] The hook unit includes a side-tilting concave hook 201, a flipping groove 202, a first positioning hook groove 203, and a steel wire sling 208;

[0032] The side-inverted concave hook 201 is sleeved on the outer edges of both ends of the steel pipe 1, and the bottom horizontal part of the side-inverted concave hook 201 is in contact with the upper surface of the inner wall of the steel pipe 1, for hooking the steel pipe 1.

[0033] The flip groove 202 is opened on the lower surface of the horizontal part of the top of the side-inverted concave hook 201, and the first positioning hook groove 203 is opened on the upper surface of the flip groove 202 and distributed at one end of the flip groove 202 near the vertical part of the side-inverted concave hook 201.

[0034] The wire sling 208 is sleeved inside the first positioning groove 203 and the other end of the wire sling 208 is hooked on the gantry crane hook, used for lifting or lowering the side-inverted concave hook 201.

[0035] The clamping unit includes a 7-shaped flipping arm 204, an arc-shaped pressure plate 205, and a second positioning slot 206;

[0036] The 7-shaped flip arm 204 is rotatably connected to the inner side of the flip groove 202 away from the first positioning groove 203. The vertical part of the 7-shaped flip arm 204 extends to the bottom of the horizontal part of the top of the side-inverted concave hook 201 and is fixedly connected to the arc-shaped pressure plate 205. The second positioning groove 206 is opened on the lower surface of the horizontal part of the 7-shaped flip arm 204.

[0037] The steel wire sling 208 is moved and hooked to the inside of the second positioning groove 206 to provide upward pulling force to the horizontal part of the 7-shaped flip arm 204, so as to realize that the arc-shaped pressure plate 205 flips down and presses against the outer surface of the steel pipe 1, thereby achieving a tight press between the bottom horizontal part of the side-inverted concave hook 201 and the steel pipe 1.

[0038] The weight of the horizontal part of the 7-shaped flip arm 204 is greater than the sum of the weight of the vertical part of the 7-shaped flip arm 204 and the weight of the arc-shaped pressure plate 205.

[0039] When the arc-shaped pressure plate 205 is in its lowest position, the distance between the lower surface of the arc-shaped pressure plate 205 and the upper surface of the bottom horizontal part of the side-inverted concave hook 201 matches the wall thickness of the steel pipe 1, and the lower surface of the arc-shaped pressure plate 205 is covered with a layer of rubber.

[0040] In this embodiment: the clamping and lifting assembly 2 performs the lifting operation on the steel pipe 1, and the operation method is as follows:

[0041] First, the wire rope sling 208 is hooked to the gantry crane hook and the first positioning slot 203 respectively to achieve the connection between the side-inverted concave hook 201 and the gantry crane. Then, the side-inverted concave hook 201 is moved closer to the upper edge of the end of the steel pipe 1 by the operation of the gantry crane.

[0042] Then, the personnel manually adjust the side-inverted concave hook 201 to a horizontal position and insert it with the opening of the side-inverted concave hook 201 aligned with the edge of the steel pipe 1, so that the top and bottom horizontal parts of the side-inverted concave hook 201 are located on the outside and inside of the steel pipe 1, respectively. It should be noted that during this process, the horizontal part of the 7-shaped flip arm 204 is tilted downward under its own weight, that is, the arc-shaped pressure plate 205 is at its highest position. The distance between the arc-shaped pressure plate 205 and the bottom horizontal part of the side-inverted concave hook 201 is greater than the wall thickness of the steel pipe 1, so it will not interfere with the insertion of the side-inverted concave hook 201.

[0043] Afterwards, the wire sling 208 can be manually moved from the inside of the first positioning groove 203 to the inside of the flipping groove 202, and the horizontal part of the 7-shaped flipping arm 204 can be raised at a certain angle. Then, the wire sling 208 can be moved to the bottom of the horizontal part of the 7-shaped flipping arm 204 so that the wire sling 208 is hooked with the second positioning groove 206.

[0044] Following the above operating steps, hook the other clamping and lifting assembly 2 to the other end of the steel pipe 1. After the two clamping and lifting assemblies 2 are installed, the gantry crane can be started to lift and tighten the two wire ropes 208. At this time, the wire ropes 208 first pull the horizontal part of the 7-shaped tilting arm 204, so that the horizontal part of the 7-shaped tilting arm 204 flips upward and fits against the top of the inner wall of the tilting groove 202. Meanwhile, the arc-shaped pressure plate 205 is driven by the 7-shaped tilting arm 204 to rotate downward and press against the outside of the steel pipe 1. The bottom horizontal part of the side-inverted concave hook 201 fits tightly against the inner wall of the steel pipe 1. In this way, the mutual clamping operation between the side-inverted concave hook 201 and the steel pipe 1 is achieved (it should be noted that the rubber layer on the arc-shaped pressure plate 205 can increase the friction between the arc-shaped pressure plate 205 and the steel pipe 1).

[0045] Afterwards, the gantry crane continues to operate and can lift the steel pipe 1 as a whole for transfer. Through the cooperation of the above-mentioned parts, the clamping and lifting assembly 2 can clamp the edge of the steel pipe 1. Compared with the traditional hook structure, it not only has a larger contact area, but also a more stable hook state, effectively avoiding the situation of disengagement, and further improving the safety of transferring large-diameter steel pipes.

[0046] Please refer to this carefully. Figures 2-5 The second positioning slot 206 has multiple slots evenly arranged in the horizontal direction along the transverse part of the 7-shaped flip arm 204.

[0047] In this embodiment: through the structural arrangement of multiple second positioning slots 206, any one of the second positioning slots 206 can be selected to provide a positioning hook for the wire sling 208, making the operation more flexible and convenient (it should be noted that the positions of the second positioning slots 206 on the two sets of clamping and hoisting components 2 to which the wire sling 208 is attached need to be consistent).

[0048] Please refer to this carefully. Figures 2-5 The top horizontal part of the side-tilting concave hook 201 is fixed with an arc-shaped baffle 207 located below the flip groove 202. The arc-shaped baffle 207 is used to limit the downward flipping of the horizontal part of the 7-shaped flip arm 204.

[0049] The arc-shaped baffle 207 is connected to the side-inverted concave hook 201 at a position far from the first positioning groove 203, and the top of the arc-shaped baffle 207 near the first positioning groove 203 does not contact the side-inverted concave hook 201.

[0050] In this embodiment: the arc baffle 207 can limit the downward flipping of the lateral part of the 7-shaped flipping arm 204, thereby preventing the downward flipping angle of the lateral part of the 7-shaped flipping arm 204 from being too large and affecting the operation of inserting the side-tilting concave hook 201 into the steel pipe 1.

[0051] Furthermore, the arc-shaped baffle 207 will not affect the operation of the wire rope sling 208 being sleeved on the first positioning slot 203.

[0052] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
