Single-power pipeline conveying mechanism

Abstract

The invention 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] The invention relates to the technical field of building construction equipment, and in particular to a single-power pipeline conveying mechanism. Background Art

[0002] During tunnel construction, it is often necessary to transport hard pipes or soft pipes (such as anchors, grouting pipes, etc.) to designated holes. The traditional method of transportation is mainly manual operation, which has obvious safety hazards. On the one hand, the tunnel construction environment is complex, and there may be dangers such as falling rocks and collapse. Manual operation undoubtedly increases the safety risks of construction workers; on the other hand, manual operation is inefficient and cannot meet the requirements of fast and efficient modern tunnel construction.

[0003] In order to improve construction efficiency and safety, some mechanized pipeline transportation equipment has appeared on the market. However, these equipment are often complex in structure and require multiple power sources to drive, which not only increases the manufacturing cost of the equipment, but also increases the difficulty of maintenance and operation. In addition, some equipment may damage the pipeline during transportation, reducing the construction quality and efficiency. Summary of the invention

[0004] The purpose of the present invention is to provide a single-power pipeline transportation mechanism, aiming to achieve full mechanization and automation of pipeline transportation, improve construction efficiency and safety, and reduce the manufacturing cost and operation difficulty of the equipment.

[0005] The present invention is implemented by adopting the following technical scheme: a single-power pipeline conveying mechanism, characterized in that it includes 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 both rotatably connected to the machine 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, the two have the same rotation speed and opposite direction, conveying rollers are arranged on the driving gear shaft and the driven gear shaft, and the conveying rollers on the driving gear shaft and the driven gear shaft respectively rotate with the driving gear shaft and the driven gear shaft.

[0006] Furthermore, an annular groove is radially arranged on the conveying roller, and 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 is pressed by the two conveying rollers. The friction between the pipeline and the conveying rollers is used to move the pipeline.

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

[0008] Furthermore, a spring is arranged on the outer side of the lower half wheel, and the compression amount of the spring can be adjusted to adjust the conveying force and avoid slipping and jamming.

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

[0010] Furthermore, the spring has an overload protection function. When the pipeline conveying force is too large, the two conveying rollers and the pipeline will slip, 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 the present invention has the following beneficial effects: (1) Improved transportation efficiency: Compared with manual pushing, the present invention can greatly improve the efficiency of pipeline transportation and shorten the construction period.

[0013] (2) Reduce costs: Due to the realization of fully mechanized operation, labor costs and safety risks are reduced, thereby reducing the overall construction cost.

[0014] (3) Improved safety: The present invention avoids direct manual contact with pipelines, reduces potential safety hazards, and improves construction safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0018] 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 invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] like Figure 1 As shown, a single-power pipeline conveying mechanism includes a driving device 1, a machine base 2, a driving gear shaft 3, a driven gear shaft 4 and a conveying roller. The driving gear shaft 3 and the driven gear shaft 4 are both rotatably connected to the machine base 2. The driving device 1 is connected to the driving gear shaft 3 and drives the driving gear shaft 3 to rotate. The driving gear shaft 3 and the driven gear shaft 4 are driven by gear meshing, and the two have the same speed but opposite directions. Conveying rollers are provided on the driving gear shaft 3 and the driven gear shaft 4, and the conveying rollers on the driving gear shaft 3 and the driven gear shaft 4 rotate with the driving gear shaft 3 and the driven gear shaft 4 respectively. An annular groove is provided on the conveying roller in the radial direction, and 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 is pressed by the two conveying rollers. The pipeline 8 is conveyed and moved by the friction between the pipeline 8 and the conveying roller.

[0020] The conveying roller is divided into an upper half wheel 5 and a lower half wheel 6. The upper half wheel 5 is fixed on the gear shaft, and the lower half wheel 6 can slide along the gear shaft. A spring 7 is arranged on the outer side of the lower half wheel 6, which can be adjusted by the compression amount of the spring 7, so as to adjust the conveying force and avoid slipping and jamming. The friction force can be increased or reduced by adjusting the moving distance of the lower half wheel 6. The spring 7 can avoid jamming and damage to the pipeline, so that it has an overload protection function. When the pipeline conveying force is too large, it has exceeded the compression force of the spring, and the two conveying wheels and the pipeline will slip, thereby avoiding damage to the pipeline and the power system; at the same time, the spring 7 can also adjust the size of the friction force. By adjusting the compression length of the spring, the compression force can be changed, thereby changing the conveying force.
