Description

Technical Field

[0001] The invention relates to the technical field of anchor rod trolleys, and in particular to a middle end drill protecting device of an anchor rod trolley. Background Art

[0002] Anchor trolleys are widely used in various underground engineering construction projects such as tunneling and underground plant excavation, mainly for blasting drilling, anchor drilling, advance drilling, grouting and other operations. In the construction process of the anchor trolley, in order to improve efficiency, the boom is required to be able to quickly and accurately position, and to conveniently and flexibly clamp the anchors in the anchor library. During the delivery of the anchor, it is necessary to prevent the anchor from bending and shaking when it is stressed, and at the same time realize the automatic opening and closing of the device at any position to meet the clamping requirements of anchors of different diameters and types. In addition, the mechanism is also required to be small in size and have a large opening distance to meet the requirement that the anchor cover plate does not interfere when passing through the clamp. In view of the working conditions of the anchor trolley system, a small-sized and large-opening anchor trolley mid-end drill protection device is specially designed to improve economy and practicality. Summary of the invention

[0003] The purpose of the present invention is to provide a middle-end drill protecting device for an anchor rod trolley, so as to solve the problem of anchor rod bending and shaking when the anchor rod is clamped and fed by the anchor rod trolley.

[0004] The present invention is implemented by adopting the following technical scheme: a mid-end drill protection device of an anchor trolley, characterized in that it includes a top plate two, a top plate one and a drill protector, the top plate two and the top plate one are connected and fixed on the advancement beam by a plurality of mounting bolts one, forming the main frame of the device, the drill protector is installed on the delivery rod pulley assembly by a plurality of mounting bolts two, and moves along the arrangement direction of the top plate two and the top plate one, and is used to play a protective role during the anchor delivery process.

[0005] Furthermore, the drill protector also includes two spring shafts, which are respectively installed on the two rotating arms to provide installation positions for the springs, and two top blocks, which are respectively installed on the two rotating arms through a number of mounting bolts to achieve a closing action under the tension of the springs to clamp the anchor rod.

[0006] Furthermore, the drill protector also includes two sliding shafts, which are installed on the two rotating arms through countersunk screws and pins, and are used to realize the opening and closing actions of the rotating arms under the action of the top plate one and the top plate two.

[0007] Furthermore, the drill protector also includes a limit baffle welding piece, which passes through the sliding shaft and is connected to the drill protector base welding piece by means of mounting bolts, so as to limit the movement range of the sliding shaft.

[0008] Furthermore, the two rotating arms are connected to the drill bit protection base welding piece by installing bolts to form a rotating arm assembly, and the spring is installed on the spring shaft to provide a pulling force when the rotating arm is closed.

[0009] Furthermore, the drill protector is moved forward and backward by means of a feed rod pulley assembly. When the drill protector is on top plate two, the upward movement of the sliding shaft drives the rotating arms to open to both sides, at which time the anchor rod is clamped onto the thrust beam; when the anchor rod continues to move forward and crosses top plate two, the lower end of the sliding shaft is suspended in the air, and the two rotating arms drive the two top blocks to close under the tension of the spring, clamping the anchor rod to prevent it from bending, shaking, etc.

[0010] Furthermore, when the drill protector pushes the anchor rod to a place on the top plate, under the action of the top plate, the sliding shaft moves upward again to drive the rotating arm to open to both sides. At this time, the front end of the anchor rod pushing mechanism can pass over the drill protector to complete the installation of the anchor rod.

[0011] The invention discloses a middle-end drill protection device for an anchor trolley, and its beneficial effects include: It solves the problem of preventing bending and shaking when the anchor trolley is subjected to force during the process of clamping the anchor and feeding it. At the same time, it can also realize the automatic opening and closing of the device at any position, reducing the disadvantages of the complex front-end mechanism. Under the premise of ensuring the stable and effective operation of the anchor trolley, it improves efficiency and saves costs. BRIEF DESCRIPTION OF THE DRAWINGS
