Description

Technical Field

[0001] The invention relates to the technical field of anchor rod trolleys, and in particular to a grouting mechanism for a mortar anchor rod trolley. Background Art

[0002] In modern tunnel construction, mortar anchor grouting is one of the important links in support construction and is widely used in tunnel rock reinforcement and stabilization. The purpose of grouting operation is to inject mortar into the anchor hole through high-pressure grouting to form a rock support structure with good strength. However, most tunnel construction sites currently still use traditional manual operation methods.

[0003] Most current grouting operations rely on manual pushing and operation of grouting pipelines. During the high-pressure grouting process, workers are exposed to the high-pressure mortar environment due to contact with the grouting pipelines. Especially when using a high-pressure pump for grouting, there is a risk of mortar splashing and injuring people. At the same time, manual operation is also prone to accidents, such as pipeline detachment and personnel slipping, which poses serious safety hazards. The existing technology has not completely solved these safety issues and still requires a large amount of manual participation in the operation.

[0004] Traditional grouting operations usually require the collaboration of multiple people, who manually push the grouting pipe into the hole, maintain the grouting pressure manually, and manually withdraw the pipe during the grouting process. The entire process takes a long time, which not only increases the construction period, but also greatly increases the labor intensity of the operators. Especially in complex and dangerous tunnel environments, manual operation efficiency is low and cannot meet the time and precision requirements of modern tunnel construction.

[0005] Due to manual operation, the control of grouting speed and pressure is unstable, resulting in uneven speed or pressure fluctuations during the grouting process, which will directly affect the grouting effect and may eventually lead to incomplete grouting of anchor rods or uneven filling of mortar, thus affecting the stability and safety of the tunnel structure. Existing grouting equipment is difficult to achieve automatic and precise control and cannot ensure the consistency of quality of each grouting.

[0006] Although some mechanized equipment, such as automatic pushing devices and grouting pumps, have been used in some tunnel construction, these devices are usually single-function devices, and most of them still require human participation. For example, some mechanical equipment can push the grouting pipeline into the hole, but it is impossible to achieve accurate withdrawal of the grouting pipeline, or the withdrawal process still requires manual control. In addition, most of the existing grouting equipment is a single robotic arm or hydraulic device, and the degree of automation of its control system is low, and it is impossible to achieve automated operation of the entire grouting process. Therefore, how to replace manual operation with mechanized equipment and improve work efficiency and construction quality is still a difficult problem in the existing technology.

[0007] At present, although some equipment has begun to try to realize partial automation functions, there is still a lack of grouting systems that can perform fully automated operations. For example, in complex or narrow tunnels, mechanical equipment is usually unable to successfully complete all grouting steps. At the same time, there is a lack of remote control systems for grouting operations, and construction personnel are unable to monitor the grouting process and adjust working parameters in real time, which increases the complexity and risk of operations.

[0008] Therefore, the existing grouting equipment has not yet been able to completely replace manual operation, and there is still much room for improvement in terms of operational safety, efficiency and quality. Summary of the invention

[0009] The purpose of the present invention is to provide a grouting mechanism for a mortar anchor trolley, which can achieve efficient, safe and high-quality control of the grouting process in a fully mechanized and automated manner to solve the safety hazards, low efficiency and unstable quality problems in the prior art.

[0010] The present invention is implemented by adopting the following technical scheme: a grouting mechanism for a mortar anchor trolley, characterized in that it includes a machine base, a guide rail, a guide sleeve one, a sliding assembly, a guide sleeve two, an oil cylinder, a pipeline driving device and a hose; wherein: the guide rail and the guide sleeve two are installed on the machine base; the sliding assembly is guided by the guide rail and the guide sleeve two, and is connected to the oil cylinder; the pipeline driving device is fixed on the sliding assembly, and is used to drive the hose to push, grout and withdraw along the axis of the hole; the oil cylinder is used to provide a reciprocating driving force for the sliding assembly; the pipeline driving device includes a group of hose driving rollers, which are used to control the movement speed and direction of the hose.

[0011] Furthermore, the pipeline driving device is fixed on the sliding assembly, and the hose is inserted into the sliding assembly; the sliding assembly is provided with an opening at the pipeline driving device, and the pipeline driving device contacts the hose through the opening and transports the hose.

[0012] Furthermore, the pipeline driving device is fixedly connected to the guide sleeve 1, the guide sleeve 1 is slidably connected to the guide rail, and the oil cylinder is connected to the guide sleeve 1.

[0013] Furthermore, the guide sleeve 2 is slidably connected to the sliding assembly, and the oil cylinder pushes the sliding assembly forward, so that the hose is pushed along the axis of the hole to a specified depth and then grouting begins.

[0014] Furthermore, the pipeline driving device is used to drive the hose to exit the hole at a set speed after the grouting is completed, and the sliding component returns to the initial state to wait for the grouting operation of the next hole.

[0015] Furthermore, the pipeline driving device clamps the hose through a group of driving rollers, and the rotation direction and speed of the driving rollers are adjustable to achieve accurate pushing and withdrawal of the hose.

[0016] Furthermore, the movement stroke of the sliding assembly is limited by the length of the guide rail and the sliding range of the guide sleeve 2, and the length of the guide rail matches the depth of the hole.

[0017] The grouting mechanism for a mortar anchor trolley of the present invention has the following beneficial effects: Realize full mechanization and automation of grouting The present invention realizes the mechanization and automation of the whole process of mortar anchor grouting operation through the coordinated work of the guide rail, guide sleeve, sliding assembly, oil cylinder and pipeline driving device, completely avoids manual operation and significantly improves the construction efficiency.

[0018] Improve construction efficiency The traditional manual grouting method is time-consuming and labor-intensive, but the present invention uses mechanized operation to make the hose pushing, grouting and withdrawal processes continuous and accurate, which not only reduces manpower input, but also significantly shortens the construction period.

[0019] Improve construction quality The pipeline drive device uses a set of hose-driven rollers, which can accurately control the push and withdraw speed of the hose, thereby ensuring uniform speed and stable pressure during the grouting process, ensuring the filling effect of the mortar and improving the construction quality.

[0020] Enhance construction safety Through mechanized operation, construction workers do not need to directly contact the high-pressure grouting pipeline, which greatly reduces the safety risks caused by mortar splashing, pipeline falling off, etc., and improves the safety of operations.
