Description

Technical Field

[0001] This utility model relates to the field of guardrail engineering equipment technology, specifically to a side-mounted power structure. Background Technology

[0002] The guardrail along the highway edge consists of a barrier panel and piles. The piles are located on the side of the barrier panel furthest from the center of the highway, with a distance of approximately ten centimeters between the piles and the barrier panel. In traditional construction vehicles, the drill rod assembly is mounted in front of the follower frame assembly. Since the lifting guide rail assembly itself has a certain size, if it is also placed on the side of the barrier panel furthest from the highway, the drill rod will be separated from the barrier panel by the size of the lifting guide rail assembly. This prevents the drill rod from drilling in the correct position. Only by raising the lifting guide rail assembly above the barrier panel can the drill rod be brought close to the barrier for drilling. However, raising the lifting guide rail assembly significantly increases structural instability, requiring the drill rod to descend further to drill, resulting in noticeable vibration during the drilling process. Utility Model Content

[0003] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a side-mounted power structure that can fix the power head to the side of the follower frame, allowing the drill rod to be drilled closer to the guardrail.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a side-mounted power structure, including a drilling assembly, a lifting guide rail assembly, and a follower frame assembly. The follower frame assembly is ellipsably mounted on the lifting guide rail assembly. The drilling assembly includes a drill rod, an impactor located at the bottom of the drill rod, a drill bit located at the bottom of the impactor, and a power head located at the top of the drill rod. The power head is located on the side of the follower frame assembly.

[0005] Preferably, an outer guide connecting frame is fixed to the side of the follower frame assembly, and the outer guide connecting frame is fixedly connected to the power head.

[0006] Preferably, the outer guide connecting frame includes a connecting plate and a positioning plate fixed on the connecting plate, the power head is fixed on the positioning plate, and the connecting plate is fixedly connected to the follower frame assembly.

[0007] Preferably, slide rails are fixed on both sides of the lifting guide rail assembly, a pressure plate one is fixed on the side of the follower frame assembly, a pressure plate two is provided on the side of the slide rail away from the pressure plate one, and a connecting plate is located between the pressure plate one and the pressure plate two; the pressure plate one, the connecting plate and the pressure plate two are fixedly connected by bolts.

[0008] Preferably, a wear-resistant plate is provided between the first pressure plate and the connecting plate, and a wear-resistant plate is provided between the second pressure plate and the connecting plate. The first wear-resistant plate extends between the first pressure plate and the slide rail, and the second wear-resistant plate extends between the second pressure plate and the slide rail.

[0009] Preferably, the outer guide connecting frame is welded to the side of the follower frame assembly.

[0010] Preferably, a lifting chain is rotatably mounted on the lifting guide rail assembly, and a lifting motor with a brake is fixed on the top of the lifting guide rail assembly.

[0012] Preferably, the front of the follower frame assembly is provided with a mounting plate for connecting the power head.

[0013] The beneficial effects of this utility model are as follows:

[0014] The power head of this invention is fixed to the side of the follower frame, which places the drill rod, impactor, and drill bit on the side of the lifting guide rail.

[0027] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1:

[0029] like Figures 1 to 9As shown, Embodiment 1 of this utility model provides a side-mounted power structure, which mainly comprises a drilling assembly 1, a lifting guide rail assembly 2, and a follower frame assembly 3. The lifting guide rail assembly 2 provides lifting guidance for the drilling assembly 1 and the follower frame assembly 3. At least two slide rails 201 are symmetrically distributed on the left and right sides of the lifting guide rail assembly 2. The follower frame assembly 3 is mounted on the lifting guide rail assembly 2 via a lifting mechanism and can move vertically along the guide rail. The lifting mechanism specifically includes a lifting chain 9 and a lifting motor 10 with a brake. Two sprockets are rotatably mounted on the lifting guide rail assembly 2, with the lifting chain 9 wound between them. The follower frame assembly 3 is fixed to the lifting chain 9. The lifting motor 10 is fixed to the top of the lifting guide rail assembly 2 and drives the sprockets to rotate, thereby allowing the follower frame assembly 3 on the lifting chain 9 to achieve lifting and lowering functions on the lifting guide rail assembly 2 as the lifting chain 9 rotates. This design is not only simple in structure but also provides stable lifting and is easy to control. The brake is generally composed of components such as brake disc, brake shoes, and brake spring. It is connected to the drive shaft or output shaft of the lifting motor 10. When braking is required, it can quickly generate braking force to stop the lifting motor 10 and keep it stationary, so that the position of the follower frame assembly 3 can be maintained.

[0030] like Figure 1 As shown, the drilling assembly 1 includes a drill rod 101, an impactor 103, a drill bit 104, and a power head 102 disposed on top of the drill rod 101. The drill rod 101 is rotatably mounted in the power head 102, and a motor for driving the drill rod 101 to rotate is fixed on the power head 102. The impactor 103 is connected to the bottom of the drill rod 101, and the drill bit 104 is disposed at the bottom of the impactor 103. The impact force generated by the impactor 103, combined with the rotational motion of the drill bit 104, can significantly improve the crushing capacity of the drill bit and increase drilling efficiency. Notably, the power head 102 is mounted on the side of the follower frame assembly 3 rather than the front. Generally, the drill rod 101 assembly, i.e., the lifting guide rail assembly 2, is disposed on the side of the engineering vehicle. When the engineering vehicle is actually operating, the lifting guide rail assembly 2 is positioned beside the road. At this time, the follower frame assembly 3 is located on the side of the lifting guide rail assembly 2 away from the engineering vehicle. The side of the follower frame assembly 3 that is away from the lifting guide rail assembly 2 and the engineering vehicle faces the edge of the road; this side is referred to as the front of the follower frame assembly 3. This utility model innovatively places the drill rod 101 assembly on the side of the follower frame, and the drill rod 101 assembly is also located on the side of the lifting guide rail assembly 2.

[0031] like Figure 9As shown, the present invention designs the drill rod 101 assembly on the side of the lifting guide rail assembly 2 and the follower frame assembly 3. In this way, when drilling, the overall height of the lifting guide rail assembly 2 can be lowered and placed on the side of the barrier away from the center of the road. At this time, the distance between the drill rod 101 and the barrier is small, and drilling can be carried out, thereby greatly reducing the overall vibration of the mechanism during drilling and making the overall structure more stable.

[0032] To achieve a stable connection between the power head 102 and the side of the follower frame assembly 3, an outer guide connecting frame 4 is fixed to the side of the follower frame assembly 3. The outer guide connecting frame 4 is fixedly connected to the power head 102.

[0033] As one possible implementation, the outer guide connecting frame 4 and the power head 102 can be welded together, and the outer guide connecting frame 4 and the follower frame assembly 3 can also be fixed by welding.

[0034] Example 2:

[0035] Based on Embodiment 1, this utility model features a detachable design for the outer guide connecting frame 4. In this second embodiment, the outer guide connecting frame 4 consists of two plates: a connecting plate 401 and a positioning plate 402. The positioning plate 402 is perpendicular to the connecting plate 401 and is fixedly connected by welding. The positioning plate 402 is bolted to the power head 102.

[0036] like Figure 5 As shown, to further enhance the stability of the structure, a pressure plate 5 is fixed to the side of the follower frame assembly 3, and a pressure plate 6 is provided on the side of the slide 201 opposite to the pressure plate 5. A connecting plate 401 is located between these two pressure plates, and the three are tightly connected together by bolts. Pressure plate 5, pressure plate 6, and connecting plate 401 respectively engage with the three surfaces of the slide 201 to form a limiting mechanism, effectively improving the stability of the drill pipe 101 assembly. Pressure plate 6 slides within the slide 201.

[0037] Example 3:

[0038] like Figure 5As shown, based on Embodiment 2, to reduce friction and wear, this invention provides wear-resistant plate 7 and wear-resistant plate 8 between pressure plate 5 and connecting plate 401, and between pressure plate 6 and connecting plate 401, respectively. Pressure plate 5, wear-resistant plate 7, connecting plate 401, wear-resistant plate 8, and pressure plate 6 are bolted together. Wear-resistant plate 7 and wear-resistant plate 8 also extend to the spaces between pressure plate 5 and slide rail 201, and pressure plate 6 and slide rail 201, respectively. Wear-resistant plates 7 and 8 protect the smooth sliding between pressure plate 5 and slide rail 201, and between pressure plate 6 and slide rail 201, enhancing the wear resistance of the sliding surfaces and extending the service life of the equipment. Wear-resistant plates 7 and 8 can be replaced according to usage. Wear-resistant plates 7 and 8 can be made of nylon material.

[0039] Example 4:

[0040] Based on the above embodiments, in order to facilitate the positioning and guidance of the drill rod 101, a drilling guide frame 11 is fixed on the lower side of the lifting guide rail assembly 2. The drill rod 101 passes through the drilling guide frame 11 during the lifting process, ensuring the accuracy and stability of the drilling.

[0041] Furthermore, considering the various installation requirements of the power head 102, this utility model also provides a mounting plate 12 for connecting the power head 102 on the front of the follower frame assembly 3. The mounting plate 12 is also connected to the power head 102 by bolts. In this way, the power head 102 can be installed from the side or the front of the follower frame assembly 3 according to actual needs, improving the flexibility and versatility of the equipment.

[0042] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
