Description

Technical Field

[0001] The utility model belongs to the field of material conveying accessories and relates to a suspension, in particular to a spring suspension for conveying equipment. Background Art

[0002] Traditional spring suspension is generally in the form of a support, spring, suspension screw and nut, without a matching spring suspension hook, which is inconvenient to use. In addition, the unmatched spring and support, suspension screw and nut are unevenly stressed during use and easily misaligned, affecting the stability of material transportation. At the same time, in a long-term working environment with uneven stress, the service life of the components will also be shortened, reducing the safety factor of the spring suspension. The use of such spring suspension will bury a great safety hazard for the material conveying line. In addition, since the conveying equipment may vibrate during operation, this will greatly increase the probability of misalignment of the traditional spring suspension. Therefore, it is even more impossible to use the traditional suspension on equipment that is prone to vibration or vibrating conveying. Utility Model Content

[0003] The utility model aims to provide a spring suspension for conveying equipment, so as to solve the technical problems in the prior art that the spring suspension is easily misplaced in a vibrating working environment, resulting in uneven force, shortened service life, and cannot be used on vibrating conveying equipment.

[0004] In order to achieve the above purpose, the specific technical solution of the utility model is as follows:

[0005] A spring suspension for conveying equipment, which includes a suspension support, a spring upper pressure cover, a compression spring and a spring lower pressure cover coaxially arranged in the suspension support from top to bottom, a suspension screw extending from the bottom of the suspension support to the top of the spring upper pressure cover, and a suspension hook located below the suspension support and arranged at the lower end of the suspension screw, the spring lower pressure cover is arranged on the upper surface of the bottom of the suspension support, the suspension screw is respectively matched with the spring upper pressure cover, the compression spring, the spring lower pressure cover and the bottom clearance of the suspension support, the upper end of the suspension screw is clamped above the upper end surface of the spring upper pressure cover through a pin shaft, and the end surfaces opposite to the spring upper pressure cover are respectively provided with clamping grooves that are interference fit with the outer diameter of the compression spring, and the upper and lower ends of the compression spring are respectively clamped in the clamping grooves of the spring upper pressure cover and the spring lower pressure cover.

[0006] The spring lower pressure cover and the hanging support are integrally formed.

[0007] A connection hole A for connecting with the conveying equipment is formed at the upper end of the hanging support.

[0008] The upper end surface of the spring upper pressure cover is provided with a hexagonal slotted nut coaxial with the hanging screw, and the pin shaft is an open pin that cooperates with the slot on the hexagonal slotted nut. The upper end of the hanging screw is punched with a hole, and the upper end of the hanging screw extends out of the hexagonal slotted nut and is fixed in the hexagonal slotted nut through the open pin.

[0009] The lower end of the hanging screw rod is integrally provided with a hanging ring, and the upper end of the hanging hook is hooked on the hanging ring.

[0010] A connecting plate is fixed to the lower end of the hanging hook, and a connecting hole B for connecting goods is provided on the connecting plate.

[0011] The beneficial effects of the utility model are as follows: the utility model provides a spring suspension for conveying equipment, by arranging a spring upper pressure cover and a spring lower pressure cover, and clamping the upper and lower ends of the compression spring in the clamping grooves of the two opposite end surfaces, so that the clamping groove and the outer diameter of the compression spring have an interference fit, and the three can be firmly connected as a whole, thereby ensuring the stability of the spring during conveying work; utilizing a hanging screw to sequentially pass through the spring upper pressure cover, the compression spring, the spring lower pressure cover and the bottom surface of the hanging support, and arranging the spring lower pressure cover and the bottom surface of the hanging support to be integrally formed, which can effectively prevent the two ends and the middle part of the compression spring from being skewed due to the vibration of the conveying equipment, resulting in uneven force on the whole spring suspension.

[0012] In addition, by passing a cotter pin through the upper end of the hanging screw and clamping the cotter pin in the hexagonal slotted nut after passing through the hanging screw, the hanging screw and the spring upper cover can be formed into a fixed connection that can be quickly disassembled, and the various parts are connected into a whole. This can prevent the hanging screw from twisting relative to the spring upper cover during the vibration conveying of the suspended material, thereby ensuring the uniformity of the force on the spring upper cover during operation, making the spring hanging structure more firm and stable during the material conveying process. At the same time, it can also achieve quick disassembly when parts need to be replaced, which is convenient and quick.

[0013] The technical solution provided by the utility model forms a mutually connected stable whole between the various components of the spring suspension of the conveying equipment, and reliable limit is formed between the components. When the conveying equipment is performing general conveying or vibration conveying, the compression spring can offset the vibration of the conveying equipment by deformation, and will not be skewed or misaligned, thereby ensuring the uniformity of the force applied to the spring suspension as a whole during operation. The simple structure is used to extend the service life of the spring suspension, and the overall safety factor of the material conveying line is improved. The utility model is suitable for promotion and application in the field of material conveying, especially in the field of material vibration conveying. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to better understand the purpose, structure and function of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings.

[0019] like Figures 1 to 3 As shown, the utility model provides a spring suspension for conveying equipment, including a suspension support 1, a spring upper pressure cover 2, a compression spring 6 and a spring lower pressure cover 3 coaxially arranged in the suspension support 1 from top to bottom, a suspension screw 4 extending from the bottom of the suspension support 1 to the top of the spring upper pressure cover 2, and a suspension hook 5 located below the suspension support 1 and arranged at the lower end of the suspension screw 4, wherein the spring lower pressure cover 3 is integrally formed with the bottom surface of the suspension support 1 and is located at the center of the bottom surface of the suspension support 1, and the suspension screw 4 is coaxial with the spring lower pressure cover 3. This arrangement can preliminarily ensure that the spring suspension can be evenly stressed during operation, thereby extending the service life of all components of the spring suspension.

[0020] In addition, the hanging screw 4 in this embodiment cooperates with the spring upper pressure cover 2, the compression spring 6, the spring lower pressure cover 3 and the bottom gap of the hanging support 1 respectively, to ensure that during the operation of the spring hanging, the hanging screw 4 can smoothly drive the compression spring 6 to expand and contract, thereby absorbing the vibration generated during the operation of the conveying device and ensuring the smooth operation of the conveying work.

[0021] In order to facilitate the replacement of the hanging screw 4 or the compression spring 6, the upper end of the hanging screw 4 is clamped above the upper end surface of the spring upper cover 2 through a pin shaft to realize the connection between the hanging screw 4 and the spring upper cover 2. In this embodiment, the pin shaft is selected as a cotter pin 8. At the same time, in order to connect the spring upper cover 2, the spring lower cover 3 and the compression spring 6 as a whole, and avoid the upper and lower ends of the compression spring 6 from being deflected, dislocated or twisted relative to the spring upper cover 2 and the spring lower cover 3 under the vibration of the conveying equipment, in this embodiment, the upper and lower ends of the spring upper cover 2 and the spring lower cover 3 are respectively provided with a clamping groove with an interference fit with the outer diameter of the compression spring 6, and the upper and lower ends of the compression spring 6 are respectively clamped into the clamping grooves of the spring upper cover 2 and the spring lower cover 3 to form a stable and firm whole, which ensures the stability of the compression spring 6 during the working process and effectively avoids the two ends of the compression spring 6 from being skewed and coming out of the spring upper cover 2 or the spring lower cover 3 when it is compressed.

[0022] Furthermore, in this embodiment, in order to facilitate the connection with the conveying equipment, a connection hole A11 connected to the conveying equipment is opened at the upper end of the hanging support 1, wherein the connection hole A11 can be a screw hole.

[0023] In addition, if Figure 1 , Figure 3 As shown, in this embodiment, a hexagonal slotted nut 7 coaxial with the hanging screw 4 is fixedly arranged on the upper end surface of the spring upper cover 2, and a split pin 8 cooperates with the slot on the hexagonal slotted nut 7. The upper end of the hanging screw 4 is punched, and the upper end of the hanging screw 4 is fixed in the hexagonal slotted nut 7 through the split pin 8 after extending out of the hexagonal slotted nut 7. This arrangement can form a stable limit for the spring upper cover 2 and the hanging screw 4, making them a stable whole, avoiding the hanging screw 4 from twisting relative to the spring upper cover 2 due to vibration during ordinary conveying and vibrating conveying, ensuring that the spring upper cover 2 is uniformly stressed during the working process, which can not only avoid its deformation and extend the service life of the spring upper cover 2, but also further ensure the stability of the spring hanging during the material conveying process.

[0024] Furthermore, in order to facilitate setting the hanging hook 5 on the hanging screw 4, in this embodiment, the lower end of the hanging screw 4 is integrally provided with a hanging ring 9, and the upper end of the hanging hook 5 is hooked on the hanging ring 9. In order to facilitate hanging materials, a connecting plate 10 is fixed to the lower end of the hanging hook 5, and a connecting hole B12 for connecting materials or material transfer boxes is provided on the connecting plate 10.

[0025] The technical solution provided in this embodiment connects the various components of the spring suspension into a whole, and can still achieve smooth transportation in a vibrating environment. Therefore, it can be applied to vibration transportation equipment. The compression spring 6 and the components connected to it will not be skewed or misaligned, ensuring uniform force between the components and smooth and reliable transportation, extending the service life of the spring suspension as a whole, and also improving the safety factor of the conveyor line.
