Description

Technical Field

[0001] The utility model belongs to the technical field of the feeding machine frame, and particularly relates to a frame structure of a feeding device. Background Art

[0002] In the fields of modern industrial production and logistics warehousing, an efficient, stable and flexible feeding device is one of the key factors to ensure the smooth production process and improve production efficiency. With the continuous improvement of industrial automation, the performance requirements for feeding devices are becoming increasingly strict. Traditional feeding devices often have problems such as insufficient frame structure strength, limited load-bearing capacity, easy deformation or damage when facing heavy and bulky materials, which not only affects the efficiency and accuracy of material handling, but also increases equipment maintenance costs and safety risks.

[0003] Specifically, the frames of traditional feeding devices are mostly made of a single metal material, such as I-beams, channel steels, etc. Although these materials have a certain load-bearing capacity, in the application scenarios of large spans and long crossbeams, their bending resistance performance often fails to meet the requirements. When the long crossbeam bears the up-and-down force from the handling mechanism, it is easy to bend and deform, resulting in a decrease in the overall stability of the frame, and further affecting the smooth handling of materials. In addition, due to the large amount of material used, traditional frames are often heavy, which not only increases the installation difficulty and transportation cost, but also limits the flexible deployment of the device in a narrow space. Summary of the Invention

[0004] Aiming at the above problems, the purpose of the utility model is to provide a frame structure of a feeding device, which solves the problems of poor stability and easy damage often caused by insufficient frame structure strength or unreasonable design of traditional feeding devices when handling heavy objects.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is: a frame structure of a feeding device, including a feeding device and a frame. The feeding device includes a fixed frame. The middle end of the upper connecting arm and one end of the oil cylinder and the lower connecting arm are rotatably connected to the side of the fixed frame through a pin shaft. The other end of the oil cylinder is rotatably connected to one end of the upper connecting arm through a pin shaft. The other ends of the upper connecting arm and the lower connecting arm are rotatably connected to a connecting rod through a pin shaft. The upper connecting arm, the lower connecting arm, the connecting rod and the fixed frame form a parallelogram link structure. The connecting rod is connected to the top end of the feeding frame. The frame includes an upper support beam. The fixed frame is installed on the upper support beam. Both ends of the upper support beam are connected with vertical rods. The bottom ends of the vertical rods are connected with both ends of a lower support beam. The lower support beam is connected with both ends of a crossbeam. The upper support beam is a steel pipe structure with double-layer upper and lower flanges and single-layer web formed by clamping a C-shaped steel plate one and a C-shaped steel plate two.

[0006] The beneficial effects of the present utility model are as follows: The upper support beam with a relatively large span can provide stable support for the feeding device during the process of the feeding device transporting materials. Moreover, while meeting the bending resistance performance, the upper support beam effectively reduces the material consumption and the weight of the frame.

[0007] To ensure the stability of the connection between the first C-shaped steel plate and the second C-shaped steel plate;

[0008] As a further improvement of the above technical solution: The first C-shaped steel plate and the second C-shaped steel plate are connected by welding.

[0009] The beneficial effect of this improvement is that the welding connection method fully ensures the connection stability between the first C-shaped steel plate and the second C-shaped steel plate.

[0010] To further ensure the stability of the connection between the first C-shaped steel plate and the second C-shaped steel plate;

[0011] As a further improvement of the above technical solution: Concave groove structures are bent and formed at the corners of the first C-shaped steel plate and the second C-shaped steel plate.

[0012] The beneficial effect of this improvement is that the groove structures can stably engage the first C-shaped steel plate and the second C-shaped steel plate with each other, ensure the connection stability between the first C-shaped steel plate and the second C-shaped steel plate, reduce the stress concentration at the corners, and improve the structural stability of the first C-shaped steel plate and the second C-shaped steel plate.

[0013] To further reduce the self-weight of the frame while ensuring the overall structural stability of the frame;

[0014] As a further improvement of the above technical solution: The lower support beam has the same structure as the upper support beam.

[0015] The beneficial effect of this improvement is that the lower support beam can still provide stable support for the frame while reducing the self-weight.

[0016] To effectively ensure the support strength of the fixing frame;

[0017] As a further improvement of the above technical solution: A reinforcing frame is welded to the side of the fixing frame. The reinforcing frame is installed on the upper support beam and is composed of a plurality of steel pipes welded together.

[0018] The beneficial effect of this improvement is that the reinforcing frame can effectively improve the structural strength of the fixing frame, thereby ensuring the stability of the feeding device when lifting materials.

[0019] To facilitate the use of the device;

[0020] As a further improvement of the above technical solution: Adjustable feet and universal wheels are installed at the bottom end of the vertical rod.

[0021] The beneficial effects of this improvement are as follows: The adjustable foot cups can be adjusted according to the unevenness of the ground to ensure the stable placement of the device, while the universal wheels facilitate the flexible movement of the device between different working areas.

[0022] Parts not involved in this device are the same as those in the prior art or can be implemented using the prior art. Description of the Drawings

Detailed Embodiment

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not have any restrictive effect on the protection scope of the present invention.

[0029] Embodiment 1:

[0030] As Figure 1As shown in Fig. 4, a frame structure of a feeding device includes a feeding device 1 and a frame 2. The feeding device 1 includes a fixed frame 8. The middle end of the upper connecting arm 4 and one end of the oil cylinder 3 and the lower connecting arm 5 are rotatably connected to the side of the fixed frame 8 through a pin shaft. The other end of the oil cylinder 3 is rotatably connected to one end of the upper connecting arm 4 through a pin shaft. The other ends of the upper connecting arm 4 and the lower connecting arm 5 are rotatably connected to the connecting rod 6 through a pin shaft. The upper connecting arm 4, the lower connecting arm 5, the connecting rod 6, and the fixed frame 8 form a parallelogram link structure. The connecting rod 6 is connected to the top end of the feeding frame 7. The frame 2 includes an upper support beam 10. The fixed frame 8 is installed on the upper support beam 10. Both ends of the upper support beam 10 are connected with vertical rods 11. The bottom ends of the vertical rods 11 are connected to both ends of the lower support beam 15. The lower support beam 15 is connected to both ends of the cross beam 14. The upper support beam 10 is a steel pipe structure with double-layer upper and lower flanges and single-layer web formed by clamping the C-shaped steel plate one 101 and the C-shaped steel plate two 102. The upper support beam 10 with a large span can provide stable support for the feeding device 1 during the process of the feeding device 1 transporting materials. At the same time, while meeting the bending resistance performance, the upper support beam 10 effectively reduces the material consumption and the weight of the frame. The C-shaped steel plate one 101 and the C-shaped steel plate two 102 are welded and connected. The welding connection method fully ensures the connection stability of the C-shaped steel plate one 101 and the C-shaped steel plate two 102. Concave groove structures are bent and formed at the corners of the C-shaped steel plate one 101 and the C-shaped steel plate two 102. The groove structures can stably engage the C-shaped steel plate one 101 and the C-shaped steel plate two 102 with each other, ensure the connection stability of the C-shaped steel plate one 101 and the C-shaped steel plate two 102, reduce the stress concentration at the corners, and improve the structural stability of the C-shaped steel plate one 101 and the C-shaped steel plate two 102. The lower support beam 15 has the same structure as the upper support beam 10. While reducing its own weight, the lower support beam 15 can still provide stable support for the frame 2. A reinforcing frame 9 is welded to the side of the fixed frame 8. The reinforcing frame 9 is installed on the upper support beam 10. The reinforcing frame 9 is composed of multiple steel pipes welded together. The reinforcing frame 9 can effectively improve the structural strength of the fixed frame 8, and then ensure the stability of the feeding device 1 when lifting materials. Adjustable foot cups 12 and universal wheels 13 are installed at the bottom ends of the vertical rods 11. The adjustable foot cups 12 can be adjusted according to the ground unevenness to ensure the device is placed stably. The universal wheels 13 facilitate the flexible movement of the device between different working areas.

[0031] The working principle of this technical solution is as follows: Place the device on one side of the processing or conveying equipment. When the oil cylinder 3 contracts to the end of its stroke, the bottom of the loading rack 7 abuts against the ground. The operator places the material on the loading rack 7, and then controls the oil cylinder 3 to extend. One end of the upper connecting arm 4 driven by the oil cylinder 3 rotates downward, causing the other end of the upper connecting arm 4 to drive the connecting rod 6 to rotate upward. While moving, the connecting rod 6 is supported and limited by the lower connecting arm 5, driving the loading rack 7 to move upward parallel to the ground, so that the material is stably transported to a high place. The operator can then push the material onto the operating platform of the processing or conveying equipment. During the process of transporting the material, the middle and both ends of the upper support beam 10 are subjected to bending stresses of being pressed from above and pulled from below. The overlapping part of the C-shaped steel plate 101 and the C-shaped steel plate 102 forms a thickened upper and lower flange. Since the middle part of the upper support beam 10 is close to the neutral layer and the stress is small, only shear failure resistance needs to be satisfied. Therefore, the single-layer web structure can still provide stable support while reducing the self-weight of the material and lowering the cost.
