[0002] A crawler crane is a common name for a crawler-type crane. It refers to a full-slewing boom crane with a crawler traveling device. A crawler crane consists of a power unit, a working mechanism, and structures such as a boom, turntable, and main platform. The chassis needs to withstand enormous pressure, so the processing and manufacturing of the main platform is very important.

[0003] When processing and fixing the main platform of the crawler crane, there are many functional mechanisms on the main platform. Most of the parts to be fixed and welded are large and have different shapes. During the positioning process, most of the parts cannot be placed straight and stably on the fixed holes or planes, and manual adjustment is required, which not only consumes manpower but also reduces the efficiency of installation and fixing. Summary of the Invention

A reinforcing spring is sleeved on the rectangular limiting slide rod. The bottom end of the reinforcing spring is fixedly connected to the arc-shaped contact block, and the top end of the reinforcing spring is fixedly connected to the C-shaped mounting plate.

[0011] Furthermore, a plurality of support rods are fixedly installed on the top of the C-shaped mounting plate, and an air box is fixedly installed on the top of the plurality of support rods. A movable rod is fixedly installed on the top of the rectangular limiting slide rod. The top of the movable rod extends into the air box and is slidably connected to the air box. A push plate is fixedly installed on the top of the movable rod. The push plate is slidably connected to the air box. Two air supply pipes are fixedly installed on the top of the air box.

[0012] Furthermore, the rectangular limiting slide bar is provided with two transmission mechanisms.

[0014] Furthermore, the method for machining fixing components on the main platform of a crawler crane comprises the following steps:

[0015] S1: Adjust the position of the part;

[0016] S2: Supporting the component from above;

[0017] S3: Support the component from below;

[0018] S4: Strengthen the support force under the part.

[0019] The present invention has the following beneficial effects:

[0020] (1) The present invention provides a machining and fixing component for the main platform of a crawler crane. When gripping a part, the lifting hydraulic cylinder and hydraulic cylinder one work together to lower the C-shaped mounting plate. When the C-shaped mounting plate is lowered to the appropriate position of the part, the drive motor is started. The drive motor drives the double threaded rod to rotate. The double threaded rod drives the two internal threaded clamping blocks to move closer to each other. The internal threaded clamping blocks moving closer will drive the two rotating anti-slip rods to move closer to each other. During the process of moving closer to each other, the rotating anti-slip rods will contact the part and clamp the part. Then, the lifting hydraulic cylinder and hydraulic cylinder one work together to raise the part. At this time, the C-shaped mounting plate will rise along with it. The C-shaped mounting plate drives the rotating anti-slip rods to rise. The rotating anti-slip rods drive the part to rise. After the part leaves the ground, the rotating anti-slip rods will rotate on the internal threaded clamping blocks. At this time, the part will adjust its angle so that the bottom surface of the part is straight and in contact with the ground. At this time, the bottom surface of the part is standing at nearly ninety degrees, which is convenient for positioning and fixing the part on the main platform, improving the efficiency and accuracy of installation.

[0021] (2) In the process of rotating the part, the lower surface of the part will rise and the part will contact the arc-shaped contact block when rotating. The arc-shaped contact block will rise. At this time, the reinforcing spring will be compressed and deformed. At this time, the arc-shaped contact block will drive the rectangular limiting slide rod to rise. After the part is adjusted to nearly 90 degrees, the reinforcing spring will press against the arc-shaped contact block under its compressed elastic force to prevent the arc-shaped contact block from continuously rising under the angle rotation of the support rod, which would cause the part to continuously rotate at an angle.

[0022] (3) In the present invention, a main platform processing fixing component for a crawler crane is provided. During the upward movement of the rectangular limiting slide rod, the two transmission rods will move closer to each other. The transmission rods will move the two C-shaped slide plates closer to each other. The C-shaped slide plates will move the L-shaped plate. The L-shaped plate will move the L-shaped round rod. The L-shaped round rod will move the adapting plate towards the part. The two adapting plates will continue to move closer after contacting the part. At this time, the part will cause the adapting plate to descend. At this time, the transmission spring will be compressed and deformed. As the two adapting plates get closer and closer to the bottom of the part, the transmission spring will be compressed more and more severely. At this time, the elastic force of the transmission spring will increase and provide strong support for the part.

[0023] (4) The present invention provides a machining fixing component for the main platform of a crawler crane. During the upward movement of the rectangular limiting slide bar, the movable rod will be driven to rise. The movable rod will drive the push plate to rise. The push plate will push the gas in the air box to rise. The gas will be gradually compressed and the air pressure will increase. The gas enters the air supply chamber through the air supply pipe and the circular air supply cylinder. The air supply chamber will generate an upward force under the action of air pressure. At this time, the adapting plate will generate an upward force. At this time, the adapting plate will generate an upward force on the part, thereby better clamping the part between the adapting plate and the arc surface contact block, improving the stability of the part during positioning and improving the positioning accuracy.

[0024] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figure 1 - Figure 8 As shown, the present invention is a machining and fixing component for a crawler crane main platform, including a C-shaped mounting plate 1, a hydraulic cylinder 2 fixedly mounted on the top of the C-shaped mounting plate 1, a drive motor 3 fixedly mounted on the left side of the C-shaped mounting plate 1, and a double threaded rod 4 rotatably mounted inside the C-shaped mounting plate 1, the double threaded rod 4 penetrating the C-shaped mounting plate 1, and further including:

[0038] Adjustment mechanism 5 includes two internal threaded clamping blocks 501 threaded onto the double threaded rod 4. A rectangular limiting rod 502 is fixedly installed inside the U-shaped mounting plate 1.

Rotating anti-slip rods 503 are rotatably installed on the side of the two internal threaded clamping blocks 501 that are close to each other. A part 504 is provided between the two rotating anti-slip rods 503 and contacts the two rotating anti-slip rods 503.

[0039] like Figure 4 As shown, an adjustment mechanism 6 is provided below the C-shaped mounting plate 1. The adjustment mechanism 6 includes a base 601 located below the C-shaped mounting plate 1. A cylinder 602 is fixedly mounted on the top of the base 601. A circular block 603 is slidably mounted inside the cylinder 602. A lifting hydraulic cylinder 604 is fixedly mounted on the top of the base 601. The output end of the lifting hydraulic cylinder 604 is slidably connected to the circular block 603.

A rotary motor 606 is fixedly mounted on the bottom inner wall of the circular mounting groove 605. A rotating shaft 607 is fixedly mounted on the output shaft of the rotary motor 606. The top end of the rotating shaft 607 extends outside the circular mounting groove 605. An adjustment platform 608 is fixedly mounted on the top end of the rotating shaft 607.

[0040] When gripping the part, the lifting hydraulic cylinder 604 and hydraulic cylinder 2 work together to lower the C-shaped mounting plate 1. When the C-shaped mounting plate 1 is lowered to the appropriate position of the part.

[0041] like Figure 5 As shown, a positioning mechanism 7 is provided on the adjustment platform 608. The positioning mechanism 7 includes a T-shaped sliding groove 701 opened in the adjustment platform 608. A hydraulic cylinder 702 is fixedly installed on the inner wall of the back side of the T-shaped sliding groove 701. A T-shaped slider 703 is slidably installed in the T-shaped sliding groove 701. The bottom end of the T-shaped slider 703 extends to the outside of the T-shaped sliding groove 701. The output shaft of the hydraulic cylinder 702 is fixedly connected to the T-shaped slider 703. The bottom end of the T-shaped slider 703 is fixedly connected to the hydraulic cylinder 2.

[0042] When adjusting the positioning of part 504, hydraulic cylinder 2 702 is activated. Hydraulic cylinder 2 702 will drive T-slider 703 to move to the corresponding position. T-slider 703 will drive part 504 below it to the designated position, thereby improving the positioning accuracy.

[0043] like Figure 3As shown, a reinforcing mechanism 8 is provided inside the C-shaped mounting plate 1. The reinforcing mechanism 8 includes a rectangular limiting slide rod 801 that is slidably mounted on the C-shaped mounting plate 1. The rectangular limiting slide rod 801 passes through the C-shaped mounting plate 1. An arc-shaped contact block 802 is fixedly installed at the bottom end of the rectangular limiting slide rod 801. A reinforcing spring 803 is sleeved on the rectangular limiting slide rod 801. The bottom end of the reinforcing spring 803 is fixedly connected to the arc-shaped contact block 802, and the top end of the reinforcing spring 803 is fixedly connected to the C-shaped mounting plate 1.

[0044] When part 504 rotates, it will contact the arc-shaped contact block 802. The arc-shaped contact block 802 will rise. At this time, the reinforcing spring 803 will undergo compression deformation. The arc-shaped contact block 802 will then drive the rectangular limit slide bar 801 to rise.

[0045] like Figure 3 , Figure 5 and Figure 6 As shown, a number of support rods 804 are fixedly installed on the top of the C-shaped mounting plate 1. An air box 805 is fixedly installed on the top of the support rods 804. A movable rod 806 is fixedly installed on the top of the rectangular limiting slide rod 801. The top of the movable rod 806 extends into the air box 805 and is slidably connected to the air box 805. A push plate 807 is fixedly installed on the top of the movable rod 806. The push plate 807 is slidably connected to the air box 805. Two air supply pipes 808 are fixedly installed on the top of the air box 805.

[0046] During the upward movement of the rectangular limit slide bar 801, the movable rod 806 will rise, the movable rod 806 will rise, the push plate 807 will rise, and the push plate 807 will push the gas in the air box 805 to rise. The gas will be gradually compressed and the air pressure will increase.

[0047] like Figure 6 and Figure 7 As shown, two transmission mechanisms 9 are provided on the rectangular limiting slide bar 801. The transmission mechanism 9 includes a transmission rod 901 hinged to the rectangular limiting slide bar 801. A limiting groove 902 is provided on the C-shaped mounting plate 1. The transmission rod 901 passes through the limiting groove 902. A C-shaped sliding plate 903 is slidably mounted on the C-shaped mounting plate 1. The end of the transmission rod 901 is hinged to the C-shaped sliding plate 903. An L-shaped plate 904 is fixedly mounted on the bottom end of the C-shaped sliding plate 903.

[0048] During the upward movement, the rectangular limiting slide bar 801 will drive the two transmission rods 901 to move closer to each other. The transmission rods 901 will drive the two C-shaped slide plates 903 to move closer to each other. The C-shaped slide plates 903 will drive the L-shaped plate 904 to move.

[0049] like Figure 7As shown, two L-shaped rods 905 are fixedly installed on the L-shaped plate 904. An adaptation plate 906 is slidably sleeved on the two L-shaped rods 905. A transmission spring 907 is sleeved on each of the two L-shaped rods 905. The top ends of the two transmission springs 907 are fixedly connected to the adaptation plate 906, and the bottom ends of the two transmission springs 907 are fixedly connected to the L-shaped plate 904. An air supply chamber 908 is opened in the adaptation plate 906. A circular air supply cylinder 909 is fixedly installed on the L-shaped plate 904. The top end of the circular air supply cylinder 909 extends into the air supply chamber 908 and is slidably connected to the air supply chamber 908. The end of the air supply pipe 808 communicates with the circular air supply cylinder 909.

[0050] Gas enters the gas delivery chamber 908 through the gas delivery pipe 808 and the circular gas delivery cylinder 909. Under the action of air pressure, the gas delivery chamber 908 generates an upward force, which in turn generates an upward force on the adapting plate 906. This force on the adapting plate 906 further clamps the part 504 better between the adapting plate 906 and the arc-shaped contact block 802, improving the stability and positioning accuracy of the part 504.

[0051] like Figure 1-8 As shown, a method for machining fasteners on the main platform of a crawler crane includes the following steps:

[0052] S1: Adjust the position of part 504;

[0053] S2: Supporting part 504 from above;

[0054] S3: Supporting part 504 from below;

[0055] S4: Strengthen the support force under the 504 stainless steel part.

[0056] When gripping the part, the lifting hydraulic cylinder 604 and hydraulic cylinder 2 work together to lower the C-shaped mounting plate 1. When the C-shaped mounting plate 1 reaches the appropriate position for the part, the drive motor 3 is started. The drive motor 3 drives the double threaded rod 4 to rotate. The double threaded rod 4 drives the two internal threaded clamping blocks 501 to move closer together. The internal threaded clamping blocks 501 moving closer together will drive the two rotating anti-slip rods 503 to move closer together. During the process of moving closer together, the rotating anti-slip rods 503 will contact the part 504 and clamp the part 504. Then, the lifting hydraulic cylinder 604 and hydraulic cylinder 2 work together to raise the part 504. At this time, the C-shaped mounting plate 1 will also rise. The C-shaped mounting plate 1 drives the rotating anti-slip rods 503 to rise, and the rotating anti-slip rods 503 drive the part 504 to rise. After the part 504 leaves the ground, the rotating anti-slip rods 503 will cause friction against the internal threaded clamping blocks 501. As the part 504 rotates, its angle adjusts so that its bottom surface is directly in contact with the ground. At this point, the bottom surface of the part 504 is at a near 90-degree angle, facilitating its positioning and fixing on the main platform and improving installation efficiency and accuracy. During the rotation of the part 504, its lower surface rises, and the part 504 contacts the arc-shaped contact block 802. The arc-shaped contact block 802 rises, and the reinforcing spring 803 undergoes compression deformation. The arc-shaped contact block 802 then drives the rectangular limiting slide rod 801 to rise. After the part 504 is adjusted to a near 90-degree angle, the reinforcing spring 803, under its compressed elastic force, holds the arc-shaped contact block 802 in place, preventing the arc-shaped contact block 802 from continuously rising as the support rod 804 rotates, thus preventing the part 504 from continuously rotating at an angle.

[0057] During its ascent, the rectangular limiting slide bar 801 causes the two transmission rods 901 to move closer together. The transmission rods 901 then cause the two U-shaped sliding plates 903 to move closer together. The U-shaped sliding plates 903 then move the L-shaped plate 904, which in turn moves the L-shaped round rod 905. The L-shaped round rod 905 then moves the adapting plate 906 closer to the part 504. After contacting the part 504, the two adapting plates 906 continue to move closer. At this point, the part 504 causes the adapting plates 906 to descend. During this process, the transmission spring 907 undergoes compression deformation. As the two adapting plates 906 get closer and closer to the bottom of the part 504, the transmission spring 907 becomes increasingly compressed, increasing its elastic force and exerting pressure on the part 504. 04. Provide strong support; during the upward movement of the rectangular limiting slide bar 801, it will drive the movable rod 806 to rise, which in turn will drive the push plate 807 to rise. The push plate 807 will push the gas in the air box 805 to rise, and the gas will be gradually compressed, increasing the air pressure. The gas enters the air supply chamber 908 through the air supply pipe 808 and the circular air supply cylinder 909. Under the action of air pressure, the air supply chamber 908 will generate an upward force. At this time, the adapting plate 906 will generate an upward force, which will exert an upward force on the part 504, thereby better clamping the part 504 between the adapting plate 906 and the arc-shaped contact block 802, improving the stability of the part 504 during positioning and improving the positioning accuracy.
