Description
技术领域technical field
本实用新型涉及一种自钻式注浆可回收锚杆，属于矿井支护设备技术领域。The utility model relates to a recyclable self-drilling grouting bolt, which belongs to the technical field of mine supporting equipment.
背景技术Background technique
目前，矿井经常使用注浆锚杆对巷道围岩进行加固，但普通的注浆锚杆均为一次性使用，这造成了支护材料的浪费，大大增加了支护成本；同时一般的注浆锚杆在注浆结束后，高压注满的水泥浆会从注浆口溢出，有时还会发生喷浆伤人事故。因此，在保证浆液不会溢出的前提下，迫切需要一种安装方便的可回收锚杆，以实现锚杆的重复利用。At present, mines often use grouting bolts to reinforce the roadway surrounding rock, but ordinary grouting bolts are used for one time, which causes a waste of support materials and greatly increases the cost of support; After the anchor bolt is finished grouting, the cement slurry filled with high pressure will overflow from the grouting port, and sometimes accidents of grouting and injury will occur. Therefore, under the premise of ensuring that the slurry will not overflow, there is an urgent need for a recyclable anchor that is easy to install, so as to realize the reuse of the anchor.
实用新型内容Utility model content
本实用新型的目的是克服已有技术的不足之处，提供一种便于安装，安全可靠，可重复使用的自钻式注浆可回收锚杆。The purpose of the utility model is to overcome the deficiencies of the prior art and provide a self-drilling grouting recyclable bolt that is easy to install, safe and reliable, and reusable.
为实现上述目的，本实用新型是通过以下技术方案实现的：In order to achieve the above object, the utility model is achieved through the following technical solutions:
一种自钻式注浆可回收锚杆，包括：中空钢管、螺母、托盘、半圆球、弹簧、支撑杆，其特征在于：所述中空钢管外表面设有螺纹，中空钢管上均匀开有出浆孔，中空钢管的下端是一锥形头，中空钢管的上端设有托盘和螺母，在中空钢管上部靠近托盘处插入一支撑杆，支撑杆上有一弹簧，弹簧与一半圆球相连。A self-drilling grouting recoverable bolt, comprising: a hollow steel pipe, a nut, a tray, a semi-circular ball, a spring, and a support rod, characterized in that: the outer surface of the hollow steel pipe is provided with threads, and the hollow steel pipe is evenly opened with holes Slurry hole, the lower end of the hollow steel pipe is a conical head, the upper end of the hollow steel pipe is provided with a tray and a nut, and a support rod is inserted near the tray at the upper part of the hollow steel pipe. There is a spring on the support rod, and the spring is connected with a half ball.
所述的螺纹深度为15～20mm，螺距为20～30mm。The thread depth is 15-20mm, and the pitch is 20-30mm.
因此，本实用新型的有益效果是：可以自钻进入软岩巷道，施工方便；注浆时可阻止浆液外流；锚杆在使用结束后可以整体回收，节约支护成本。Therefore, the beneficial effects of the utility model are: it can self-drill into the soft rock roadway, and the construction is convenient; it can prevent the slurry from flowing out during grouting; the bolt can be recovered as a whole after use, saving support costs.

具体实施方式Detailed ways
为了使本实用新型实现的技术特征与达成目的易于了解，下面结合附图，进一步阐述本实用新型。In order to make the technical features and objectives realized by the utility model easy to understand, the utility model will be further elaborated below in conjunction with the accompanying drawings.
如图1所示，一种自钻式注浆可回收锚杆，包括：中空钢管1、螺母2、托盘3、半圆球4、弹簧5、支撑杆6。其特征是：所述中空钢管1外表面设有螺纹7，中空钢管1上均匀开有出浆孔8，中空钢管1的下端是一锥形头9，中空钢管1的上端设有托盘3和螺母2，在中空钢管1上部靠近托盘处插入一支撑杆6，支撑杆6上有一弹簧5，弹簧5与一半圆球4相连。As shown in FIG. 1 , a self-drilling grouting recoverable bolt includes: a hollow steel pipe 1 , a nut 2 , a tray 3 , a semicircular ball 4 , a spring 5 , and a support rod 6 . It is characterized in that: the outer surface of the hollow steel pipe 1 is provided with thread 7, the hollow steel pipe 1 is evenly opened with a slurry hole 8, the lower end of the hollow steel pipe 1 is a conical head 9, and the upper end of the hollow steel pipe 1 is provided with a tray 3 and Nut 2 inserts a support rod 6 near the pallet at the hollow steel pipe 1 top, a spring 5 is arranged on the support rod 6, and the spring 5 links to each other with the half ball 4.
采用本实用新型的自钻式注浆可回收锚杆，可以直接钻进围岩，便于安装；当浆液从注浆口进入锚杆体时，半圆球将通道变成单向通道，可以阻止浆液外溢；当锚杆使用结束后，锚杆可以直接反向旋出，实现整体的回收，从而节约支护成本。The self-drilling grouting recyclable rock bolt of the utility model can be directly drilled into the surrounding rock, which is convenient for installation; when the grout enters the bolt body from the grouting port, the semi-circular ball turns the channel into a one-way channel, which can prevent the grout from Overflow; when the anchor rod is used, the anchor rod can be directly unscrewed in the opposite direction to achieve overall recovery, thereby saving support costs.
