Description

Technical Field

[0001] This utility model relates to the field of underground cavern construction technology, specifically to a self-propelled drilling and blasting trolley for underground caverns. Background Technology

[0002] Pumped storage power stations utilize the drill-and-blast method to excavate underground caverns. Self-made steel-structured drill-and-blast rigs are used for drilling and loading explosives. However, the long distances between caverns and the constraints of cross-sectional dimensions and blasting safety distances necessitate the use of loaders for movement during each blasting cycle, which can easily lead to rig deformation and severely impact construction efficiency and safety, particularly affecting the water conveyance system. Drill-and-blast rigs are crucial machinery for drilling and anchor bolt installation in tunnel, underground, and mining operations, primarily used in railways, highways, mines, underground facilities, and disaster relief environments. With the implementation of "automation replacing manpower, mechanization reducing manpower," the use of drill-and-blast rigs for drilling blast holes is widely adopted in mountain tunnel construction.

[0003] The description of a mobile drilling and blasting rig for small-section tunnels (publication number CN209875155U) mentions that "the mobile drilling and blasting rig for small-section tunnels includes a mobile platform and an operating platform. A steel frame is provided under the operating platform, which is welded and fixed to the mobile platform. Toe plates are provided around the operating platform. The mobile platform is replaced by a mining dump truck. After the mobile drilling and blasting rig for small-section tunnels enters the work site, the tires are fixed with limiters." However, the operating platform frame of the drilling and blasting rig in the prior art is small and has a small protection range, which not only affects the working range but also lacks stable and comprehensive protection. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, a self-propelled drilling and blasting trolley for underground caverns is provided to solve the problems of small operating platform frames and small protection range on existing drilling and blasting trolleys, which not only affect the operating range but also lack stable and comprehensive protection.

[0005] To achieve the above objectives, a self-propelled drilling and blasting trolley for underground caverns is provided, comprising a lower body and a drilling and charging platform. The drilling and charging platform is mounted on the lower body, and a base is provided at the bottom of the drilling and charging platform. Two sets of support columns are vertically fixed on both the front and rear sides of the upper end of the base, and a top seat is fixed on the upper end of the support columns. A guardrail is fixed on the front side of the upper end of the top seat. A horizontal fixing beam is fixed in the middle of the inner side of the support columns, and multiple sets of vertical fixing beams are fixed on the outer side of the support columns.

[0006] Furthermore, an outer frame plate is fixed to the upper part of the outer side of the support column steel, and a rear fixing plate is fixed to the upper part of the support column steel on the rear side of the upper end of the base.

[0007] Furthermore, diagonal bracing plates are fixed on both the left and right sides of the vertical fixed beam, and the diagonal bracing plates are made of 114 I-beams.

[0008] Furthermore, a second mesh is fixed to the outer side of the outer frame plate, and a first mesh is fixed to the upper part of the outer side of the base. The second mesh and the first mesh are parallel vertically, and both the second mesh and the first mesh adopt a steel mesh structure.

[0009] Furthermore, a ladder is installed between the outer frame plate and the rear of the base, and the clear width of the ladder is set to 40cm, with each step of the ladder being 40cm.

[0010] Furthermore, telescopic rods are installed in the middle of both the left and right sides of the base.

[0011] Furthermore, the lower part of the top seat is provided with multiple sets of horizontal steel ribs, and the lower part of the top seat is provided with multiple sets of vertical steel ribs. The horizontal steel ribs and the vertical steel ribs intersect perpendicularly, and the upper surfaces of the horizontal steel ribs and the vertical steel ribs are provided with a steel mesh structure.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The frame structure of this utility model drilling and charging platform is welded and installed firmly, which is not only safe and durable, but also stable and reliable during use, so as to ensure long-term safe use in underground caverns.

[0014] 2. The second and first mesh panels in this utility model are designed for reliable side protection, ensuring the safety of workers operating on the side. The ladders are designed to facilitate climbing, and the double-sided ladders are more stable and convenient.

[0015] 3. The longitudinal and transverse steel ribs in the top seat of this utility model are not only sturdy and firm, but the steel mesh structure on them also provides tight top safety protection to prevent stones from falling, making it safer and more reliable. Attached Figure Description
