Description

Technical Field

[0001] This utility model relates to the field of mechanical clamping, and in particular to a dual-support adjustable lifting device. Background Technology

[0002] In daily production and processing, a large number of flanged cylindrical workpieces need to be clamped, lifted, and transferred. Currently, the common lifting method is to use a sufficiently long sling, which is inserted into one end of the cylindrical part and passes through a hole on the other end face or outer circumference. Then, both ends of the sling are directly hooked onto the overhead crane hook to complete the lifting. With this lifting method, the cylindrical workpieces are mostly in a "flat" or "semi-flat" position. When it is necessary to place the workpiece with its end face close to the workbench in a "vertical" direction, multiple lifting operations and changes in the position of the sling are required to complete the task.

[0003] Thus, the existing technology has the following problems: each cylinder needs to be secured with slings, which is time-consuming and labor-intensive; the point on the outer circle of the end face that first contacts the workbench is very easy to be bumped; and the risk to the operators is relatively high during the entire lifting process.

[0004] There is currently no effective solution to the above problems in existing technologies. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a dual-support adjustable lifting device. By controlling the rotation of two supports around a first pin shaft until the first and second clamping rods rotate to a suitable position to clamp the cylinder, and by adjusting the cooperation between the mounting block and the boss to fix the relative position of the two supports, the cylinder can be lifted quickly and effectively. This solves the problems of inconvenience, unsafety, and easy wear and tear in cylinder lifting in the prior art.

[0006] To achieve the above objectives, this utility model provides a dual-support adjustable lifting device, comprising: a first support, the first support including an integrally formed first sub-rod, a second sub-rod, and a first clamping rod, the second sub-rod extending from one end of the first sub-rod to one side, forming a first step at the transition point, a first included angle between the first sub-rod and the second sub-rod, and the first clamping rod extending from one end of the second sub-rod to one side; a second support, the second support including an integrally formed third sub-rod, a fourth sub-rod, and a second clamping rod, the fourth sub-rod extending from one end of the third sub-rod to one side, forming a second step at the transition point, the angle of the second included angle between the third sub-rod and the fourth sub-rod being the same as the first included angle, the second clamping rod extending from one end of the fourth sub-rod to one side and being disposed opposite to the first clamping rod; a first pin passing through the first step and the second step to movably connect the first support and the second support; and an adjusting block, the adjusting block having multiple adjusting grooves sequentially opened longitudinally, one end of the adjusting block being movably connected to the first sub-rod via a second pin, and being engaged with a protrusion on the third sub-rod via one of the adjusting grooves.

[0007] Optionally, the first sub-rod has a first lifting hole near its free end; the second sub-rod has a second lifting hole near its free end.

[0008] Further optionally, a limiting block is also included; the limiting block is fixedly connected to one end of the first pin that passes through the second step.

[0009] Further optionally, the top surface of the first clamping rod is provided with anti-slip texture; the top surface of the second clamping rod is provided with anti-slip texture.

[0010] Alternatively, all the adjustment grooves are U-shaped grooves, and the openings of all the adjustment grooves face the same side.

[0012] Alternatively, the first included angle may be a right angle or an acute angle.

[0013] Alternatively, the first step and the second step can be adapted to each other, and after they overlap, they can be connected by a first pin.

[0021] 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.

[0022] To address the problems of inconvenience, susceptibility to impact, and safety associated with lifting cylinders using slings in existing technologies, this utility model provides a dual-support adjustable lifting device. Figure 1 This is a structural schematic diagram of the dual-support adjustable lifting device provided in this embodiment of the utility model, as shown below. Figure 1As shown, the device includes: a first support 1, comprising an integrally formed first sub-rod 101, a second sub-rod 102, and a first clamping rod 103; the second sub-rod 102 extends from one end of the first sub-rod 101 to one side, forming a first step 105 at the junction; a first angle is formed between the first sub-rod 101 and the second sub-rod 102; and a second support 2, comprising an integrally formed third sub-rod 201, a fourth sub-rod 202, and a second clamping rod 203; the fourth sub-rod 202 extends from one end of the third sub-rod 201 to one side, forming a first step 105 at the junction; and a second support 2, comprising an integrally formed third sub-rod 201, a fourth sub-rod 202, and a second clamping rod 203; the fourth sub-rod 202 extends from one end of the third sub-rod 201 to one side, forming a first step 105 at the junction. A second step 204 is formed at the location. The angle of the second included angle formed between the third sub-rod 201 and the fourth sub-rod 202 is the same as the first included angle. The second clamping rod 203 extends from one end of the fourth sub-rod 202 to one side and is set opposite to the first clamping rod 103. The first pin 4 passes through the first step 105 and the second step 204 to movably connect the first bracket 1 and the second bracket 2. The adjusting block 5 has multiple adjusting grooves in a longitudinal sequence. One end of the adjusting block 5 is movably connected to the first sub-rod 101 through the second pin 6 and is locked on the boss 205 opened on the third sub-rod 201 through one of the adjusting grooves.

[0023] like Figure 1 As shown, the device includes two opposing supports, namely a first support 1 and a second support 2, which are similar in shape. Figure 2 As shown, the first support 1 includes a first sub-rod 101 and a second sub-rod 102. The first sub-rod 101 and the second sub-rod 102 are integrally formed and at a certain angle. The included angle between the two is the first included angle. The transition point between the first sub-rod 101 and the second sub-rod 102 is a first step 105. The thickness of the step is less than the thickness of the sub-rod. A clamping rod protrudes from the end of the second sub-rod 102, namely the first clamping rod 103. The top surface of the first clamping rod 103 can be used to clamp the cylinder.

[0024] like Figure 3 As shown, the second support 2 includes a third sub-rod 201 and a fourth sub-rod 202. The third sub-rod 201 and the fourth sub-rod 202 are integrally formed and at a certain angle. The included angle between them is the same as the first included angle. The transition point between the third sub-rod 201 and the fourth sub-rod 202 is a second step 204. The thickness of this step is less than the thickness of the sub-rod. A clamping rod protrudes from the end of the fourth sub-rod 202, namely the second clamping rod 203. The top surface of the second clamping rod 203 can be used to clamp the cylinder. A circular boss 205 is provided on the third sub-rod 201.

[0025] The first bracket 1 and the second bracket 2 are connected by a first pin 4. Specifically, the first pin 4 passes through the first step 105 of the first bracket 1 and the second step 204 of the second bracket 2 in sequence to connect the first bracket 1 and the second bracket 2, and both the first bracket 1 and the second bracket 2 can rotate around the first pin 4.

[0026] An adjusting block 5 is also connected to the first sub-rod 101 via a second pin 6. The second pin 6 can be fixedly connected to the first sub-rod 101. The adjusting block 5 can rotate around the second pin 6. The adjusting block 5 is provided with multiple adjusting grooves in the longitudinal direction. The relative position of the first bracket 1 and the second bracket 2 can be fixed by hanging one of the adjusting grooves on the boss 205.

[0027] As an optional implementation, the first sub-rod 101 has a first lifting hole 104 near its free end; the second sub-rod 102 has a second lifting hole near its free end.

[0028] like Figure 2 , Figure 3 As shown, in order to facilitate lifting, a first lifting hole 104 is provided on the first sub-rod 101 near the free end, and a second lifting hole is provided on the second sub-rod 102 near the free end, so that the device and the cylinder can be lifted together by using a hook or sling.

[0029] As an optional implementation, a limiting block is also included; the limiting block is fixedly connected to one end of the first pin 4 that passes through the second step 204.

[0030] The first pin 4 passes through the first step 105 and the second step 204 and then connects to the limiting block to prevent the first pin 4 from falling off.

[0031] As an optional implementation, the top surface of the first clamping rod 103 is provided with anti-slip texture 3; the top surface of the second clamping rod 203 is provided with anti-slip texture 3.

[0032] like Figure 2 , Figure 3 As shown, the top surface of the first clamping rod 103 is provided with anti-slip texture 3, and the top surface of the second clamping rod 203 is also provided with anti-slip texture 3, thereby increasing friction and improving clamping firmness.

[0033] As an optional implementation, all adjustment grooves are U-shaped grooves, and the openings of all adjustment grooves face the same side.

[0034] like Figure 1 As shown, the adjustment grooves are all U-shaped grooves, and the openings all face the same side, which makes it easy for the U-shaped grooves to be installed in the boss 205.

[0035] As an optional implementation, four adjustment slots are provided.

[0036] The adjustment grooves are evenly distributed on the right side of the adjustment block 5.

[0037] As an alternative implementation, the first included angle is a right angle or an acute angle.

[0038] As an optional implementation, the first step 105 and the second step 204 are adapted to each other, and the two can be connected by the first pin 4 after they overlap.

[0039] like Figure 2 , Figure 3 As shown, the first step 105 and the second step 204 are adapted to each other, and the thickness of the two after overlapping is consistent with the thickness of the sub-rod.

[0040] like Figure 4 As shown, the principle of this device is as follows: the first support 1 and the second support 2 are connected by the first pin 4 and can rotate separately. When the two supports are rotated until the end with the anti-slip texture 3 is in the appropriate position, the adjusting block 5 is rotated so that one of its adjusting grooves fits into the circular boss 205 of the second support 2. At this time, the first support 1 and the second support 2 cannot rotate around the first pin 4, and the distance between the ends of the two supports with the anti-slip texture 3 will remain constant, thereby fixing the two supports to ensure that the double-support adjustable lifting device B can firmly clamp the cylinder A.

[0041] Operating steps:

[0042] ① The first pin passes through both the first bracket and the second bracket to connect them;

[0043] ② Securely connect the limiting block to the first pin to prevent it from falling off;

[0044] ③ Insert the adjusting block into one end of the cylindrical part of the second pin and fix it to the first bracket;

[0045] ④ Insert the anti-slip textured ends of the first and second brackets into the inner circular shell of the cylindrical part, and rotate the two brackets so that the two clamping rods with anti-slip textured ends support the inner circle of the shell, and the surface where the anti-slip texture is located is in close contact with the inner circular end face of the shell flange.

[0046] ⑤ Maintain the existing posture of the device, rotate and adjust the mounting block so that its appropriate U-shaped groove position fits into the boss of the second bracket, and complete the posture fixation;

[0047] ⑥ Use slings, hooks, and other tools to clamp the first and second supports, thus completing the preparation for lifting.

[0048] The above technical solution has the following beneficial effects: simple structure, convenient operation, and quick clamping of cylindrical workpieces with flanges; it can automatically center and adapt to the inner circle size of the workpiece when clamping the inner circle; it can quickly tighten and loosen the inner circle of the workpiece, which is convenient and fast; the present invention has a simple structure, is easy to manufacture, and has strong universality; it realizes the vertical lifting, vertical transportation, and vertical placement of the workpiece, and keeps the axis of the cylindrical part in the vertical direction throughout the process.
