Description

Technical Field

[0001] The utility model belongs to the field of fixture design, and relates to an internally expanding metal rod coil fixture capable of multi-degree-of-freedom adjustment. Background Art

[0002] Metal rod coils are widely used in people's daily lives, and the materials include metals, iron, aluminum, etc., and are widely used in the manufacture of automobiles, ships, chemical equipment, electronic devices, aerospace, and so on.

[0003] Currently, manufacturers of metal rod coils all carry out warehousing operations manually. The demand for labor has increased explosively with the demand for metal rod coils, and the working intensity of workers is extremely high, making it difficult to complete warehousing operations. In addition, during the warehousing operation of metal rod coils, the risk of personnel being dropped or smashed always exists. Coupled with the increased working intensity, personnel are extremely prone to fatigue, and the operation safety is difficult to guarantee. Therefore, the demand for unmanned warehousing operations of metal rod coils is becoming increasingly urgent.

[0004] Current manual operations involve multiple hoisting operations by the overhead crane. Each hoisting operation involves ground auxiliary personnel to complete actions such as specifying the hoisting position, placing the hoisting hook, resisting the sway of the overhead crane cable, specifying the loading position, and detaching the hook. There is a risk of the overhead crane colliding with personnel, and it consumes a large amount of operation time, making it difficult to improve the efficiency.

[0005] During the operation, the hoisted metal rod coils are often above people. When weighing, the metal rod coils are manually assisted to be placed, and there are also people standing on the truck carriage to assist in placing the metal rod coils, posing a great risk of personnel being dropped or smashed. Content of the Utility Model

[0006] In view of this, the purpose of the utility model is to provide an internally expanding metal rod coil fixture capable of multi-degree-of-freedom adjustment, which cooperates with unmanned construction machinery to avoid the collision of the overhead crane hoisting with personnel from the source and improve safety and operation efficiency.

[0007] To achieve the above purpose, the utility model provides the following technical solution: An internally expanding metal rod coil fixture capable of multi-degree-of-freedom adjustment, including an upper frame assembly connected to the dipper stick, the upper frame assembly is connected with a middle frame, and the middle frame is rotationally connected with the upper frame assembly through a deflection cylinder; a tensioning oil cylinder is fixedly arranged inside the middle frame, and the free end of the tensioning oil cylinder is respectively connected with an expansion plate through two symmetrically arranged link mechanism components.

[0008] Optionally, the link mechanism component includes a first connecting piece fixedly connected to the bottom of the tensioning oil cylinder, and a second connecting piece hinged to the connecting rod.

[0009] Optionally, the second connecting piece is arranged in a structure with three arms, the three arms are concentrically arranged and have equal structural lengths. One of the three arms is hinged to the first connecting piece, one is fixedly connected to the expansion plate, and the other is hinged inside the middle frame through a fixing piece.

[0010] Optionally, the distances between adjacent arms are equal.

[0011] Optionally, a limiting baffle is further provided at one end of the middle frame close to the expansion plate.

[0012] Optionally, the height of the limiting baffle is not lower than the top of the expansion plate.

[0013] Optionally, the tensioning oil cylinder and the deflection cylinder are connected with a bucket rod auxiliary oil circuit.

[0014] The beneficial effects of the present utility model are as follows: The present utility model provides an internally expandable metal rod coil clamp that can be adjusted in multiple degrees of freedom, realizing the process of inserting and transporting the metal rod coil by using the clamp. There is no need for personnel to specify the hanging position of the metal rod coil, place the lifting hook, specify the loading position, unhook, etc., which greatly improves the operation efficiency. At the same time, there is no need for personnel to assist in unhooking on the truck, reducing the risk of falling during high-altitude operations and improving safety.

[0023] Please refer to Figures 1 to 2 , which is an internally expanding metal rod coiling fixture that can be adjusted with multiple degrees of freedom, including an upper frame assembly 7 connected to the dipper stick. The upper frame assembly 7 is connected with a middle frame 1, and the middle frame 1 is rotationally connected to the upper frame assembly 7 through a deflection cylinder 6; a tensioning oil cylinder 5 is fixedly arranged inside the middle frame 1, and the free end of the tensioning oil cylinder 5 is respectively connected with an expansion plate 3 through two symmetrically arranged link mechanism 2 assemblies. The link mechanism 2 assembly includes a first connecting piece fixedly connected to the bottom of the tensioning oil cylinder 5, and a second connecting piece hinged to the connecting rod. The second connecting piece is configured with a structure having three arms. The three arms are concentrically arranged and have equal structural lengths. One of the three arms is hinged to the first connecting piece, one is fixedly connected to the expansion plate 3, and the other is hinged inside the middle frame 1 through a fixing piece. The distance between adjacent arms is equal. A limit baffle 4 is further arranged at one end of the middle frame 1 close to the expansion plate 3. The height of the limit baffle 4 is not lower than the top of the expansion plate to prevent the fixture from being inserted too deep and contacting the floor, resulting in damage to the fixture. The tensioning oil cylinder 5 and the deflection cylinder 6 are connected to the dipper stick auxiliary oil circuit.

[0024] When the utility model is in use, the oil pump of the construction machinery provides hydraulic oil for the tensioning cylinder 5 to complete the telescoping; the telescoping of the cylinder is used to complete the opening and closing of the fixture. When the cylinder extends, the expansion plate opens, and when the cylinder contracts, the expansion plate 3 contracts; the expansion plate 3 expands and closes according to the states of the link mechanism 2 and the cylinder, and is used to closely adhere to the inner wall of the metal rod coil, so that the metal rod coil will not slip during transportation.

[0025] In this embodiment, the deflection cylinder 6 is connected to the boom accessory oil circuit, so that the fixture can deflect in the left and right directions. The upper frame assembly 7 is connected to the boom, and the telescoping of the boom hydraulic cylinder is used to complete the swinging of the fixture in the up and down directions.

[0026] The utility model is used in cooperation with the construction machinery, and the hydraulic pump of the construction machinery and multiple hydraulic oil circuits are used to provide power for the fixture. The fixture is offset upward or downward, left and right, and finally the fixture is opened and closed, realizing the multi-degree-of-freedom grasping of the metal rod coil.

[0027] 1) Safety: The current traditional storage operation method for metal rod coils is manual operation of the overhead crane and manual assistance for coil picking and placing. During the operation process, there are operations such as specifying the hanging position, placing the lifting hook for assistance, loading assistance, unhooking, etc. on the ground and on the truck to assist the overhead crane operation. There are risks such as the overhead crane colliding with personnel, personnel falling from the truck, and the metal rod coil falling and smashing from a height. After changing to the multi-degree-of-freedom internal expansion type fixture for metal rod coils, the construction machinery can be used to grasp the metal rod coil, reducing the steps of manual coil picking. At the same time, no manual assistance is required on the truck during coil placing. Even for manual operation, no personnel are required to assist on the ground or on the truck, fundamentally improving the overall safety.

[0028] 2) Efficiency: During the operation of the manual overhead crane to perform tasks, a large number of operation actions such as unhooking and placing the lifting hook and specifying the loading position involve communication and cooperation between ground personnel and the overhead crane driver. After deploying the multi-degree-of-freedom internal expansion type fixture for metal rod coils on the construction machinery, there is no need for communication and cooperation between ground personnel and operators, simplifying the steps, and the operation efficiency will be greatly improved.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the purpose and scope of the present technical solution, and they should all be covered within the scope of the claims of the present utility model.
