AI Technical Summary
Technical Problem
The existing double-arm anchor bolt trolley is too heavy to perform drilling and anchor bolting work simultaneously, resulting in inaccurate positioning and low work efficiency.
Method used
The drilling arm assembly and anchor bolt assembly are designed separately to complete drilling and anchor bolting work respectively. They are equipped with grouting pipes and mud mixing systems to enable drilling and anchor bolting to be carried out simultaneously. The clamping effect is improved by front and rear clamps.
Benefits of technology
It improved work efficiency, reduced weight, enhanced positioning accuracy, increased installation flexibility and versatility, and enabled simultaneous drilling and anchoring.

Abstract
This utility model relates to a dual-arm drilling, injection, and anchoring integrated trolley, including a chassis and a frame assembly mounted on the chassis. The frame assembly is equipped with a drilling arm assembly for drilling and an anchor arm assembly for anchoring. The anchor arm assembly includes an anchor rod, a front clamp, a rear clamp, and a first telescopic propulsion beam for driving the rear clamp forward or retract. The front and rear ends of the anchor rod are connected to the front and rear clamps respectively, and the front and rear clamps are located on the first telescopic propulsion beam. The dual-arm drilling, injection, and anchoring integrated trolley obtained by this utility model has the following advantages: the separate design of the drilling arm assembly and the anchor arm assembly allows each arm to complete drilling and anchoring work respectively, enabling simultaneous drilling and anchoring, improving work efficiency. Simultaneously, the weight of the two arms is reduced, resulting in higher positioning accuracy, smaller overall mass, and stronger versatility; the front and rear clamps provide dual clamping of the anchor rod, resulting in good clamping effect and more flexible installation.
