Description

Technical Field

[0001] This utility model relates to the field of composite cast steel parts technology, and in particular to a high-strength composite cast steel part. Background Technology

[0002] Composite cast steel parts refer to castings made by combining two or more metal materials with different compositions, properties or structures in a liquid or semi-solid state through a special casting process to form a whole.

[0003] Chinese Patent Publication No. CN219220960U, published on June 20, 2023, discloses a tightly connected high-strength composite cast steel part, including a first cast steel part, a second cast steel part, and a connector. The connector has an axially arranged U-shaped channel inside. The opposite ends of the first and second cast steel parts are inserted into the U-shaped channel. The top surfaces of the first and second cast steel parts located inside the U-shaped channel are provided with multiple positioning grooves. Multiple tie rods are provided above the connector. The top surface of the connector is provided with a rectangular opening opposite the positioning groove. The bottom surface of the tie rods is provided with a positioning block opposite the rectangular opening.

[0004] Existing high-strength composite cast steel parts achieve rapid alignment of structural and connecting parts by setting retractable positioning blocks on the connectors and creating notches on the structural parts. This further improves the connection strength between the structural and connecting parts. However, in practice, multiple sets of positioning blocks need to be manually pulled by pull rods to completely separate the notches. Overcoming the elasticity of multiple sets of springs is inconvenient. Therefore, there is an urgent need to propose corresponding high-strength composite cast steel parts to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a high-strength composite cast steel part in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-strength composite cast steel part includes a structural component and a connecting component. A spacer is fixedly connected to the inner wall of the connecting component. The structural component and the connecting component are fixedly connected by a fastening screw. A side strip is fixedly connected to the outer wall of the connecting component. A rotating screw is rotatably connected to the top of the side strip. A fixed seat and a lifting assembly for vertically raising and lowering the fixed seat are integrated on the outside of the rotating screw. A wedge-shaped telescopic sleeve is connected to the bottom of the fixed seat by a spring. The outer wall of the wedge-shaped telescopic sleeve is engaged with the outer wall of the notched outer wall.

[0008] Preferably, a sleeve is fixedly connected to the outer wall of the side strip, and the outer wall of the sleeve is provided with a constraint part for axial constraint of the rotating screw.

[0009] Preferably, the constraint part includes a reinforcing rod that is screwed into the outer wall of the sleeve, and the open end of the reinforcing rod abuts against the outer wall of the rotating screw.

[0010] Preferably, a mounting plate is fixedly connected to the outer wall of the side strip, and the mounting plate is fixedly connected to the outer wall of the connector by a locking rod.

[0011] Preferably, the lifting assembly includes a lifting bar and a limiting part for axial limiting of the lifting bar, the lifting bar is fixedly connected to the fixed base, and the inner surface of the lifting bar is screwed into the outer surface of the rotating screw.

[0012] Preferably, the limiting part includes a limiting rod fixedly connected to the inner surface wall of the side strip, and the outer surface wall of the limiting rod is slidably connected to the inner surface wall of the lifting strip.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. In this application, as the structural component is attached to the connector, the wedge-shaped telescopic sleeve first yields and compresses the spring, then engages with the slot through the spring, followed by the structural component contacting the spacer, and finally the connector and structural component are fixed by the fastening screw. The wedge-shaped telescopic sleeve can achieve rapid alignment of the structural component and connector, while also increasing the vertical connection strength between the structural component and connector. Subsequently, by turning the screw with a wrench, the lifting bar is linked to the fixing seat, and the fixing seat is pulled by the spring to completely separate the wedge-shaped telescopic sleeve from the notch, thereby facilitating the lifting and maintenance of the position of the wedge-shaped telescopic sleeve, thus improving the ease of use of the high-strength composite cast steel parts.

[0015] 2. In this application, the reinforcing rod is rotated to engage with the outer wall of the sleeve until the open end of the reinforcing rod abuts against the outer side of the head of the rotating screw. The axial reinforcement of the rotating screw is achieved through the contact friction between the open end of the reinforcing rod and the rotating screw, which prevents the rotating screw from loosening and further improves the stability of the high-strength composite cast steel parts.

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] A high-strength composite cast steel part includes a structural component 1 and a connecting component 2. A spacer 6 is fixedly connected to the inner surface wall of the connecting component 2. The structural component 1 and the connecting component 2 are fixedly connected by a fastening screw 3. A side strip 4 is fixedly connected to the outer surface wall of the connecting component 2. A rotating screw 7 is rotatably connected to the top of the side strip 4. A fixed seat 10 and a lifting assembly for vertical lifting of the fixed seat 10 are integrated on the outside of the rotating screw 7. A wedge-shaped telescopic sleeve 11 is connected to the bottom of the fixed seat 10 by a spring. The outer surface wall of the wedge-shaped telescopic sleeve 11 is engaged with the outer surface wall of the notch 5.

[0025] As structural component 1 is attached to connector 2, wedge-shaped telescopic sleeve 11 first yields and compresses the spring, then attaches to notch 5 via the spring. Next, structural component 1 contacts spacer 6, and finally, connector 2 and structural component 1 are fixed by fastening screw 3. Wedge-shaped telescopic sleeve 11 can achieve quick alignment of structural component 1 and connector 2, while also increasing the vertical connection strength between structural component 1 and connector 2. Subsequently, by turning screw 7 with a starter, lifting bar 9 is linked to fixing seat 10. Fixing seat 10 pulls wedge-shaped telescopic sleeve 11 completely away from notch 5 via spring, thus facilitating the lifting and maintenance of the position of wedge-shaped telescopic sleeve 11, thereby improving the ease of use of high-strength composite cast steel parts.

[0026] Specifically, such as Figure 2 and Figure 4As shown, a sleeve 8 is fixedly connected to the outer wall of the side strip 4. The outer wall of the sleeve 8 is provided with a constraint part for axially constraining the rotating screw 7. The constraint part includes a reinforcing rod 14 that is screwed into the outer wall of the sleeve 8. The open end of the reinforcing rod 14 abuts against the outer wall of the rotating screw 7. The reinforcing rod 14 is rotated to screw into the outer wall of the sleeve 8 until the open end of the reinforcing rod 14 abuts against the outer side of the head of the rotating screw 7. The axial reinforcement of the rotating screw 7 is achieved through the contact friction between the open end of the reinforcing rod 14 and the rotating screw 7, which prevents the rotating screw 7 from loosening, thereby further improving the stability of the high-strength composite cast steel parts.

[0027] Specifically, such as Figure 2 and Figure 3 As shown, a mounting plate 13 is fixedly connected to the outer wall of the side strip 4. The mounting plate 13 is fixedly connected to the outer wall of the connector 2 via a locking rod, thereby ensuring the ease of disassembly and assembly of the side strip 4. The lifting assembly includes a lifting bar 9 and a limiting part for axial limiting of the lifting bar 9. The lifting bar 9 is fixedly connected to the fixed seat 10, and the inner wall of the lifting bar 9 is screwed into the outer wall of the rotating screw 7. The limiting part includes a limiting rod 12 fixedly connected to the inner wall of the side strip 4. The outer wall of the limiting rod 12 is slidably connected to the inner wall of the lifting bar 9. By twisting the rotating screw 7, the lifting bar 9 is linked to the fixed seat 10. The fixed seat 10 is completely separated from the notch 5 by the wedge-shaped telescopic sleeve 11 pulled by the spring.

[0028] Working principle: As structural component 1 is attached to connector 2, wedge-shaped telescopic sleeve 11 first yields and compresses the spring, then engages with notch 5 via the spring. Next, structural component 1 contacts spacer 6, and finally, connector 2 and structural component 1 are fixed by fastening screw 3. Wedge-shaped telescopic sleeve 11 enables rapid alignment of structural component 1 and connector 2 while increasing the vertical connection strength between them. Subsequently, turning screw 7 by turning screw 7 with a starter causes lifting bar 9 to link with fixing seat 10, and fixing seat 10 is pulled by spring. The movable wedge-shaped telescopic sleeve 11 is completely separated from the notch 5, which allows for convenient lifting and maintenance of the position of the wedge-shaped telescopic sleeve 11, thereby improving the ease of use of the high-strength composite cast steel parts. The reinforcing rod 14 is rotated to screw into the outer wall of the sleeve seat 8 until the open end of the reinforcing rod 14 abuts against the outer side of the head of the rotating screw 7. The axial reinforcement of the rotating screw 7 is achieved through the contact friction between the open end of the reinforcing rod 14 and the rotating screw 7, preventing the rotating screw 7 from loosening, thereby further improving the stability of the high-strength composite cast steel parts.

[0029] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
