Abstract
The utility model provides an anchor rod auxiliary centering and grouting device in the technical field of anchor spraying support, which comprises a centering ring, wherein a centering hole which can be just matched with an anchor rod is formed in the centering ring, a plurality of support rods are distributed in the circumferential direction of the centering ring, and idler wheels are rotatably connected to the support rods; the utility model saves time and is convenient to install.
Description
Technical Field
The utility model belongs to the technical field of anchor spraying support, and particularly relates to an anchor rod auxiliary centering and grouting device.
Background
The anchor spraying support refers to reinforcing the rock stratum by the combined action of high-pressure spraying cement concrete and metal anchor rods driven into the rock stratum, and is divided into a temporary support structure and a permanent support structure. The anchor spraying support construction relates to the processes of hole distribution, drilling, anchor rod or anchor cable installation and the like.
At present, the anchor rod is installed to the anchor rod hole in time and labor consuming, and the main reason is that the anchor rod centering is mostly used welded reinforcing steel bar at present as centering support, is put into the anchor rod hole that drills after the welding is accomplished, and the welding point is many, and because there is great frictional force in anchor rod centering support and anchor rod hole, leads to the anchor rod installation difficulty, needs many people to cooperate. In addition, when the grouting pipe and the anchor rod are simultaneously fed into the anchor hole during anchor rod support, the friction force between the grouting pipe and the anchor rod and the wall of the anchor hole is more obvious, so that the anchor rod is time-consuming and labor-consuming to install, the anchor rod is more difficult to install under the condition of longer anchor design length, and the problem of low working efficiency is caused.
Disclosure of utility model
Aiming at the defects in the prior art, the utility model aims to solve the defects in the prior art, solve the technical problem of inconvenient use in the prior art, and provide the anchor rod auxiliary centering and grouting device which is convenient to use and high in working efficiency.
The purpose of the utility model is realized in the following way: the utility model provides an auxiliary centering of stock, slip casting device, includes the centering ring, it has just can with stock matched with centering hole to open on the centering ring, a plurality of bracing piece has been arranged along circumference direction to the centering ring, rotationally be connected with the gyro wheel on the bracing piece.
When the anchor rod centering device is used, firstly, the anchor rod is inserted into the centering hole of the centering ring, so that the anchor rod is matched with the centering ring, then, the anchor rod centering device and the anchor rod are placed into the anchor hole together, the roller wheel is attached to the inner wall of the anchor hole, and rolls along the inner wall of the anchor hole along with the continuous movement of the anchor rod to the depth of the anchor hole until the anchor rod and the anchor rod centering device reach the position of setting the depth of the anchor hole, and the centering installation of the anchor rod in the anchor hole is completed; compared with the prior art, the utility model has the beneficial effects that: the centering ring and the roller are arranged, so that the centering installation of the anchor rod is facilitated, the roller rolls when the anchor rod penetrates into an anchor hole, the friction force between the anchor rod and the wall of the anchor hole can be reduced when the anchor rod is installed, time and labor are saved, the use is convenient, and the working efficiency is improved; can be applied to the work of anchor spraying support.
As a further improvement of the utility model, at least one binding ring is arranged on the outer side of the centering ring, the binding ring is arranged between two adjacent support rods, and the binding ring is provided with a jack.
As a further development of the utility model, the support bar is provided with three.
As a further improvement of the utility model, the included angle between the two support rods is 120 degrees.
As a further improvement of the utility model, the binding ring is integrally formed with the centering ring.
Drawings
Fig. 1 is a side view of the present utility model.
Fig. 2 is a front view of the present utility model.
In the figure: 1. the anchor eye, 2 centering ring, 3 constraint ring, 4 gyro wheels, 5 bracing piece, 6 centering hole, 7 jack.
Detailed Description
The utility model is further described below with reference to the accompanying drawings.
The auxiliary centering and grouting device for the anchor rod comprises a centering ring 2, wherein a centering hole 6 which can be just matched with the anchor rod is formed in the centering ring 2, a plurality of support rods 5 are distributed on the centering ring 2 along the circumferential direction, the support rods 5 are provided with three, the included angle between the two support rods 5 is 120 degrees, the support rods 5 are rotatably connected with idler wheels 4, the advancing direction of the wheels is parallel to the central line of the centering ring 2, at least one binding ring 3 is arranged on the outer side of the centering ring 2, the binding ring 3 and the centering ring 2 are integrally formed, the binding ring 3 is arranged between two adjacent support rods 5, and jacks 7 are formed in the binding ring 3.
When the anchor rod is assembled, the components such as the centering ring 2, the binding ring 3, the supporting rod 5 and the like can be connected together by welding or injection molding, and the like; the centering ring 2 and the roller 4 are arranged, so that the centering installation of the anchor rod is convenient, and when the anchor rod penetrates into the anchor hole 1, the roller 4 rolls, so that the friction force with the inner wall of the anchor hole 1 is reduced, the time and the labor are saved, the anchor rod installation process flow can be effectively and simply carried out, and the construction efficiency is improved; one or more devices can be selected according to the length of the anchor rod to perform auxiliary centering installation so as to prevent the anchor rod and the grouting pipe from being bent due to overlong length, and the installation is convenient; ; can be applied to the work of anchor spraying support.
The utility model is not limited to the above embodiments, and based on the technical solutions disclosed in the utility model, those skilled in the art may make some substitutions and modifications to some technical features without creative effort according to the technical disclosure, and these substitutions and modifications are all within the protection scope of the utility model.
