Description

Technical Field

[0001] This utility model belongs to the field of support frame technology, and in particular relates to a hinge beam support frame for a six-sided top press. Background Technology

[0002] As a core piece of equipment for the synthesis of superhard materials, the six-sided top press uses a hinged beam, a key component that bears high-pressure loads. During installation, maintenance, and workstation adjustments in the workshop, it requires a specialized support frame for short-distance movement. Currently, the hinged beam support frames used in the industry have significant technical defects, making it difficult to meet the requirements for efficient and safe transfer. Specific problems are as follows:

[0003] First, the mobility modes are limited and the adaptability is poor. One type of support frame can only achieve rolling translation, but its fixed wheel set is prone to getting stuck when facing obstacles commonly found on workshop floors, such as track joints, concrete protrusions, and cable trench edges. Multiple operators are required to push it with tools, which is not only inefficient but may also damage the wheels or scratch the bottom of the hinge beam. Another type can overcome obstacles, but it uses a fixed structure where the support feet and wheels coexist. During translation, the support feet slide against the ground, greatly increasing the resistance. Additional traction equipment is required, which increases the investment cost and makes it difficult to use in workshop corners without power.

[0004] Secondly, mode switching is cumbersome and requires multi-person collaboration. Most existing support frames with translation and obstacle-crossing capabilities are modular designs, requiring step-by-step adjustments to the support leg height and disassembly / reassembly of wheel positioning components during switching. This involves numerous steps, is time-consuming, and necessitates multi-person cooperation, making single-person operation impossible. Furthermore, the lack of temporary fixing structures during switching makes the support frame prone to one-sided suspension, posing a safety hazard of hinge beam tilting.

[0005] In summary, existing support frames have significant shortcomings in terms of mobility adaptability and ease of operation, necessitating the development of a new type of support frame that integrates multiple movement modes and is easy to operate. To address this, we provide a six-sided top press hinged beam support frame to solve the aforementioned problems. Utility Model Content

[0006] The purpose of this utility model is to provide a hinged beam support frame for a six-sided top press. By combining the support frame assembly and the telescopic lever assembly, it solves the problem that the support frame in the prior art has obvious deficiencies in terms of mobility adaptability and ease of operation.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0008] This utility model relates to a hinge beam support frame for a six-sided top press, comprising a support frame assembly. A telescopic lever assembly is movably connected to the inner cavity of the support frame assembly. The support frame assembly includes a frame body. Wheels are fixedly connected to the front and rear ends of one side of the bottom of the frame body. An upper limit rod and a lower limit rod are fixedly connected to the upper and lower ends of the other side of the inner cavity of the frame body, respectively. A rotating shaft is fixedly connected to the inner cavity of the frame body between the upper and lower limit rods. The telescopic lever assembly includes a sleeve fitted onto the surface of the rotating shaft. A short rod is fixedly connected to one side of the sleeve. A pin hole is formed on the surface of the short rod. A sleeve rod is fitted onto the surface of the short rod. Through holes are formed on both the upper and lower sides of the sleeve rod near the sleeve. Installation holes are formed around the through holes. A pin rod is inserted into the inner cavity of the through holes. A spring is fixedly connected to the inner cavity of the installation hole. The other end of the spring is fixedly connected to the pin rod. A limit sleeve is threadedly connected to the surface of the sleeve rod.

[0009] The present invention is further configured such that a limiting ring is fixedly connected to the surface of the rotating shaft, and a limiting nut is threaded to the other end of the rotating shaft. The limiting ring and the limiting nut cooperate to provide axial limiting for the sleeve sleeved on the surface of the rotating shaft, preventing the sleeve from falling off the rotating shaft during rotation around the rotating shaft, ensuring the stability of the connection between the sleeve and the rotating shaft, and ensuring the normal operation of the overall structure of the telescopic lever assembly.

[0010] The present invention is further configured such that a limiting plate is fixedly connected to the surface of the sleeve rod and the side near the mounting hole. The limiting plate contacts the inner wall of the limiting sleeve. The contact between the limiting plate and the inner wall of the limiting sleeve can limit the movement range of the limiting sleeve along the surface of the sleeve rod, avoid excessive movement of the limiting sleeve to compress the spring or disengage from the sleeve rod, ensure the stable control effect of the limiting sleeve on the pin rod and spring, and prevent the adjustment failure of the telescopic lever assembly due to the displacement of the limiting sleeve.

[0011] The present invention is further configured such that a handle is fixedly connected to the surface of the limiting sleeve, and a rubber sleeve is provided on the surface of the handle. The handle is easy for the operator to hold and rotate the limiting sleeve, thereby reducing the force required for rotation.

[0012] The present invention is further configured such that the pin holes are designed to be symmetrical in the upper and lower parts and distributed at equal distances in the left and right sides. The symmetrical pin holes in the upper and lower parts and the equal distances in the left and right sides allow the pin rod to be inserted into the short rod pin holes from the upper and lower sides of the sleeve rod, ensuring the uniformity of the force.

[0013] The present invention is further configured such that one end of the pin extends into the inner cavity of the pin hole, and an arc-shaped plate is fixedly connected to the end of the pin away from the pin hole. The end of the spring away from the mounting hole is fixedly connected to the arc-shaped plate. The arc-shaped plate can increase the contact area between the spring and the pin, so that the spring force is evenly applied to the pin, avoiding damage to the spring due to excessive local force. At the same time, it is convenient for the limiting sleeve to control the extension and retraction of the pin by squeezing the arc-shaped plate.

[0014] The present invention is further configured such that the inner wall of the limiting sleeve contacts the surface of the arc-shaped plate. When the limiting sleeve is rotated and moves along the sleeve rod, the limiting sleeve can directly squeeze the arc-shaped plate, thereby pushing the pin rod to insert into the pin hole to fix the short rod and the sleeve rod. After the adjustment is completed, the limiting sleeve is rotated in the opposite direction, and the spring pushes the arc-shaped plate to reset so that the pin rod disengages from the pin hole, thereby realizing the rapid adjustment of the short rod and the sleeve rod and simplifying the adjustment operation.

[0015] The present invention has the following beneficial effects.

[0016] 1. The wheels of this utility model can achieve smooth horizontal movement. When facing obstacles such as workshop track joints and concrete protrusions, the telescopic lever assembly can be adjusted to assist in overcoming obstacles. By rotating the sleeve around the pivot and adjusting the extension and retraction of the short rod and sleeve, the height of the support point and the force angle can be changed to avoid wheel jamming. At the same time, there is no need to use a fixed structure where the support foot and the wheel coexist. There is no additional sliding friction during horizontal movement, and no need to rely on traction equipment. This reduces the intensity of operation and avoids wheel damage and scratches on the bottom surface of the hinge beam. It is suitable for different workshop ground environments and improves the efficiency of short-distance transportation.

[0017] 2. This utility model achieves quick and convenient structural adjustment through the cooperation of a pin, spring, and limiting sleeve. Under the action of the spring, the rod can be stably inserted into the short rod pin hole, thus fixing the length of the short rod and the sleeve rod. Rotating the limiting sleeve controls the extension and retraction of the pin, without the need to disassemble or assemble the positioning parts. Furthermore, the upper and lower limit rods of the support frame assembly can limit the rotation range of the telescopic lever assembly, preventing one side from being suspended during the switching process. The entire switching process does not require multiple people to cooperate and can be completed by a single person. At the same time, it eliminates the safety hazard of the hinge beam tilting, greatly improving the convenience and safety of operation. Attached Figure Description

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Please see Figure 1-5 This utility model relates to a hinge beam support frame for a six-sided top press, comprising a support frame assembly 1, with a telescopic lever assembly 2 movably connected to the inner cavity of the support frame assembly 1. The support frame assembly 1 includes a frame body 11, with wheels 12 fixedly connected to both the front and rear ends of one side of the bottom of the frame body 11. An upper limit rod 13 and a lower limit rod 14 are fixedly connected to the upper and lower ends of the other side of the inner cavity of the frame body 11, respectively. A rotating shaft 15 is fixedly connected to the inner cavity of the frame body 11 between the upper limit rod 13 and the lower limit rod 14. The rod assembly 2 includes a sleeve 21 fitted onto the surface of the rotating shaft 15. A short rod 22 is fixedly connected to one side of the sleeve 21. A pin hole 23 is opened on the surface of the short rod 22. A sleeve rod 24 is fitted onto the surface of the short rod 22. Through holes are opened on both the upper and lower sides of the end of the sleeve rod 24 near the sleeve 21. A mounting hole 25 is opened around the periphery of the through hole. A pin rod 26 is inserted into the inner cavity of the through hole. A spring 27 is fixedly connected to the inner cavity of the mounting hole 25. The other end of the spring 27 is fixedly connected to the pin rod 26. A limit sleeve 28 is threadedly connected to the surface of the sleeve rod 24.

[0028] Specifically: The frame body 11 is made of high-strength metal material and has an overall rectangular frame structure to stably bear the weight of the hinge beam. The wheels 12 are made of wear-resistant rubber material and have anti-slip texture on the outside to ensure stable contact with the ground during translation. The upper limit rod 13 and the lower limit rod 14 are both cylindrical rods, which are parallel to each other and perpendicular to the side wall of the frame body 11. They are used to limit the rotation range of the telescopic lever assembly 2. The pivot 15 is a solid metal rod with a smooth surface and its axis is parallel to the upper limit rod 13 and the lower limit rod 14, which facilitates smooth rotation after the sleeve 21 is fitted.

[0029] Example 2

[0030] Please see Figure 1-5Based on Embodiment 1, a limiting ring 16 is fixedly connected to the surface of the rotating shaft 15, and a limiting nut 17 is threadedly connected to the other end of the rotating shaft 15. A limiting plate 29 is fixedly connected to the surface of the sleeve rod 24 and the side near the mounting hole 25. The limiting plate 29 contacts the inner wall of the limiting sleeve 28. A handle is fixedly connected to the surface of the limiting sleeve 28, and a rubber sleeve is fitted on the surface of the handle. The pin hole 23 is designed to be symmetrical from top to bottom and distributed at equal distances from left to right. One end of the pin rod 26 extends into the inner cavity of the pin hole 23. An arc plate is fixedly connected to the end of the pin rod 26 away from the pin hole 23. The end of the spring 27 away from the mounting hole 25 is fixedly connected to the arc plate. The inner wall of the limiting sleeve 28 contacts the surface of the arc plate.

[0031] Specifically: The limiting ring 16 and the limiting nut 17 cooperate to axially limit the sleeve 21 fitted on the surface of the rotating shaft 15, preventing the sleeve 21 from falling off the rotating shaft 15 during rotation, ensuring the stability of the connection between the sleeve 21 and the rotating shaft 15, and ensuring the normal operation of the overall structure of the telescopic lever assembly 2. The limiting plate 29 contacts the inner wall of the limiting sleeve 28, which can limit the range of movement of the limiting sleeve 28 along the surface of the sleeve rod 24, preventing the limiting sleeve 28 from moving excessively and squeezing the spring 27 or detaching from the sleeve rod 24, ensuring the stable control effect of the limiting sleeve 28 on the pin rod 26 and the spring 27, and preventing the telescopic lever assembly 2 from failing to adjust due to the displacement of the limiting sleeve 28. The handle is easy for the operator to hold and rotate the limiting sleeve 28, reducing the force required for rotation. The holes 23 are symmetrically distributed vertically and equidistantly horizontally, allowing the pin 26 to be inserted into the pin hole 23 of the short rod 22 from both the upper and lower sides of the sleeve rod 24, ensuring uniform force distribution. The arc-shaped plate increases the contact area between the spring 27 and the pin 26, allowing the spring force of the spring 27 to be evenly applied to the pin 26, preventing damage from excessive localized force on the spring 27. Simultaneously, it facilitates the control of the pin 26's extension and retraction by the limiting sleeve 28 pressing the arc-shaped plate. When the limiting sleeve 28 rotates and moves along the sleeve rod 24, it can directly press the arc-shaped plate, thereby pushing the pin 26 into the pin hole 23 to fix the short rod 22 and the sleeve rod 24. After adjustment, rotating the limiting sleeve 28 in the opposite direction causes the spring 27 to push the arc-shaped plate back to its original position, disengaging the pin 26 from the pin hole 23. This enables rapid adjustment of the short rod 22 and the sleeve rod 24, simplifying the adjustment operation.

[0032] The working principle of this utility model is as follows: First, the hinge beam of the six-sided top press is placed on the frame body 11 of the support frame assembly 1. The frame body 11 bears the weight of the hinge beam. Then, the handle on the surface of the limiting sleeve 28 is rotated, causing the limiting sleeve 28 to move along the surface of the sleeve rod 24. The limiting sleeve 28 moves away from the pin rod 26, and the spring 27 returns to its original position, pushing the arc plate and the pin rod 26 away from the pin hole 23, thus separating the sleeve rod 24 from the short rod 22. After adjusting to a suitable length, the limiting sleeve 28 is reversed. Then, the limiting sleeve 28 moves and presses the arc plate. The arc plate compresses the spring 27 and drives the pin rod 26 to insert into the pin hole 23, thus fixing the sleeve rod 24 and the short rod 22 relatively. When smooth translation is required, the telescopic lever assembly 2 will encounter the upper limit rod 13 when rotating upward. The telescopic lever assembly 2 continues to rotate upward, causing the frame body 11 to tilt forward. The forward tilt exceeds one... After the limit is set, the frame body 11 will continue to tilt forward under gravity, and then the lower limit rod 14 will lock the telescopic lever assembly 2. At this time, the two wheels 12 in front of the frame body 11 are in good contact with the ground, and the telescopic lever assembly 2 can be used to push the frame body 11 to move horizontally. When it is necessary to climb over the steps, the telescopic lever assembly 2 will hit the lower limit rod 14 when it rotates downward. The telescopic lever assembly 2 continues to rotate downward, causing the frame body 11 to tilt backward. At this time, the bottom front end of the frame body 11 will be a certain distance off the ground. At this time, the telescopic lever assembly 2 can be used to push forward to cross the small steps. During this process, the limiting ring 16 and the limiting nut 17 on the rotating shaft 15 prevent the sleeve 21 from falling off, and the limiting plate 29 on the sleeve rod 24 limits the range of movement of the limiting sleeve 28, ensuring the stable operation of the overall structure and realizing convenient switching between horizontal movement and obstacle crossing modes and safe support.
