Single-power pipeline conveying mechanism

Abstract

The utility model provides a single-power pipeline conveying mechanism. The single-power pipeline conveying mechanism comprises a driving device, a machine base, a driving gear shaft, a driven gear shaft and a conveying roller. The driving gear shaft and the driven gear shaft are in meshing transmission through gears and have the same rotating speed and opposite directions. The conveying rollers are arranged on the gear shafts and rotate along with the gear shafts, annular grooves are formed in the rollers, and the annular grooves in the two rollers are matched to form an annular conveying face used for pressing and conveying a pipeline. The conveying roller is divided into an upper half wheel and a lower half wheel, and the lower half wheel can slide in the axial direction of the gear shaft and is pressed and adjusted through a spring. By adjusting the compression amount of the spring, the conveying force can be adjusted, and the phenomena of slipping and jamming are avoided. When the conveying force of the pipeline is too large, the overload protection function of the spring enables the two conveying rollers and the pipeline to slip, and therefore the pipeline and a power system are protected against damage. In addition, by adjusting the pressing length of the spring, the conveying force can be changed, and different conveying requirements are met.

Description

Technical Field

[0001] This utility model relates to the field of construction equipment technology, and in particular to a single-power pipeline conveying mechanism. Background Technology

[0002] During tunnel construction, it is often necessary to transport rigid or flexible pipes (such as anchor bolts and grouting pipes) into designated holes. Traditional methods primarily rely on manual operation, which presents significant safety hazards. Firstly, the tunnel construction environment is complex, with potential dangers such as falling rocks and collapses; manual operation undoubtedly increases the safety risks for construction workers. Secondly, manual operation is inefficient and cannot meet the demands of modern tunnel construction for speed and efficiency.

[0003] To improve construction efficiency and safety, mechanized pipeline conveying equipment has emerged on the market. However, these devices are often complex in structure, requiring multiple power sources to operate, which not only increases manufacturing costs but also raises the difficulty of maintenance and operation. Furthermore, some equipment may damage pipelines during the conveying process, reducing construction quality and efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a single-power pipeline conveying mechanism, which aims to achieve full mechanization and automation of pipeline conveying, improve construction efficiency and safety, and at the same time reduce the manufacturing cost and operation difficulty of the equipment.

[0005] This utility model is achieved using the following technical solution: a single-power pipeline conveying mechanism, characterized in that it includes a driving device, a base, a driving gear shaft, a driven gear shaft, and conveying rollers. The driving gear shaft and the driven gear shaft are both rotatably connected to the base. The driving device is connected to the driving gear shaft and drives the driving gear shaft to rotate. The driving gear shaft and the driven gear shaft are driven by gear meshing, and their rotation speeds are the same but opposite in direction. Conveying rollers are provided on both the driving gear shaft and the driven gear shaft, and the conveying rollers on the driving gear shaft and the driven gear shaft rotate with the driving gear shaft and the driven gear shaft, respectively.

[0006] Furthermore, the conveying rollers are provided with annular grooves along the radial direction. The annular grooves on the two conveying rollers cooperate to form an annular conveying surface. The pipeline is inserted into the annular conveying surface and pressed by the two conveying rollers. The pipeline is conveyed by the friction between the pipeline and the conveying rollers.

[0007] Furthermore, the conveying roller is divided into an upper half and a lower half. The upper half is fixed on the gear shaft, and the lower half can slide along the gear shaft axis.

[0008] Furthermore, a spring is provided on the outer side of the lower half wheel, which can be adjusted by the compression of the spring to adjust the conveying force and prevent slippage and jamming.

[0009] Furthermore, one end of the spring is fixed, and by adjusting the fixed position of the spring, the distance the lower half wheel moves can be adjusted, thereby increasing or decreasing the friction between the pipeline and the conveying roller.

[0010] Furthermore, the spring has an overload protection function. When the pipeline conveying force is too large, the two conveying rollers will slip with the pipeline, thereby avoiding damage to the pipeline and the power system.

[0011] Furthermore, one end of the spring is fixed by a bolt, and the bolt is threadedly connected to the gear shaft.

[0012] The single-power pipeline conveying mechanism described in this utility model has the following advantages:

[0013] (1) Improved transport efficiency: Compared with manual pushing, this utility model can greatly improve the efficiency of pipeline transport and shorten the construction cycle.

[0014] (2) Reduced costs: Due to the realization of fully mechanized operation, labor costs and safety risks are reduced, thereby reducing the overall construction cost.

[0015] (3) Improved safety: This utility model avoids direct manual contact with the pipeline, reduces safety hazards, and improves construction safety. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] like Figure 1 As shown, a single-powered pipeline conveying mechanism includes a drive unit 1, a base 2, a drive gear shaft 3, a driven gear shaft 4, and conveying rollers. Both the drive gear shaft 3 and the driven gear shaft 4 are rotatably connected to the base 2. The drive unit 1 is connected to the drive gear shaft 3 and drives it to rotate. The drive gear shaft 3 and the driven gear shaft 4 are driven by gear meshing, and their rotational speeds are the same but opposite in direction. Conveying rollers are provided on both the drive gear shaft 3 and the driven gear shaft 4, and these rollers rotate with the drive gear shaft 3 and the driven gear shaft 4, respectively. Annular grooves are provided radially on the conveying rollers. The annular grooves on the two conveying rollers cooperate to form an annular conveying surface. The pipeline 8 is inserted into the annular conveying surface and pressed together by the two conveying rollers. The pipeline 8 is conveyed by the friction between it and the conveying rollers.

[0022] The conveying rollers are divided into an upper half 5 and a lower half 6. The upper half 5 is fixed on the gear shaft, while the lower half 6 can slide axially along the gear shaft. A spring 7 is installed on the outer side of the lower half 6. The compression of the spring 7 can be adjusted to regulate the conveying force, prevent slippage and jamming, and increase or decrease the friction by adjusting the distance the lower half 6 moves. The spring 7 prevents jamming and damage to the pipeline, providing overload protection. When the conveying force in the pipeline is too high, exceeding the spring's clamping force, the two conveying rollers will slip against the pipeline, thus preventing damage to the pipeline and the power system. Simultaneously, the spring 7 can also adjust the friction force by changing the clamping length, thereby changing the conveying force.

[0023] The above embodiments describe the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
