Description

Technical Field

[0001] The utility model relates to the technical field of mining machinery, in particular to a power source vehicle for a tunnel drilling rig. Background Art

[0002] A mining crawler hydraulic tunnel drill rig is a type of mining machinery specially used for drilling in underground tunnels (tunnels). It usually consists of a main machine and a power station. The main machine is equipped with a travel module (travel diesel engine / motor, travel crawler, etc.) and a drilling module (gripper, power head, hydraulic winch, etc.). The power station is equipped with a power module (electric motor, triple pump, etc.). The power module is responsible for providing hydraulic driving force for the drilling module to realize the main machine's operations such as drilling down and lifting the drill.

[0003] In the existing technology, the power station is usually directly installed on the crawler platform of the main body and combined with the main machine into a whole, which occupies a large space. As a result, it is difficult for the drilling rig to pass through the narrow and turning areas of the tunnel, making the overall crawler tunnel drilling rig less maneuverable. If it is considered to be configured separately from the main machine, there is currently a lack of dedicated transportation equipment, and manual transportation makes it difficult for the power station to move along with the main machine, which is not only unsafe, but also affects the construction efficiency of the project and increases the economic cost of the project.

[0004] The technical problem to be solved by the utility model is to address the deficiencies of the existing technology and provide a power source vehicle for a crawler hydraulic tunnel drill specially designed for mining, which has flexible steering and heavy-load transportation capabilities and is suitable for narrow tunnel environments.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A power source vehicle for a tunnel drilling rig is characterized by comprising a transport platform and a crawler assembly mounted below the transport platform, the crawler assembly comprising a traveling crawler and a traveling motor for controlling the traveling crawler, a power module and a load-bearing module being provided at the front of the transport platform, and a water supply module and a drive module being provided at the rear of the transport platform;

[0007] The power module includes a support frame fixed on the transport platform, wherein a triple pump and a first motor driving the triple pump are sequentially arranged inside the support frame from front to back, and a plurality of power connectors connected to the drilling equipment on the main machine are arranged at the front of the triple pump;

[0008] The carrying module includes a transport platform provided on the left and right sides of the support frame, and is used to carry the drill rod. Each platform is provided with a positioning component to prevent the drill rod from falling.

[0009] The water supply module includes a mud pump and a second motor driving the mud pump, which are sequentially arranged on the transport platform from front to back. The front of the mud pump is provided with a liquid delivery connector connected to the power head on the main engine;

[0010] The driving module is arranged on either side of the water supply module, and includes a driving device fixedly installed on the transport platform. The power output end of the driving device is connected to the travel motor through a hydraulic pump.

[0011] The technical problem to be solved by the present invention can be further achieved by the following steps: a distribution box is installed on the upper front end of the support frame, a hydraulic oil tank is installed on the support frame behind the distribution box, and an auxiliary lifting ring is provided on the hydraulic oil tank for easy lifting.

[0012] The technical problem to be solved by the present invention can be further achieved by the following steps: protective nets for facilitating heat dissipation are installed on the frames on the left and right sides of the support frame.

[0013] The technical problem to be solved by the present invention can be further achieved by the following steps: the loading platform is fixedly connected to the transport platform as a whole, and the positioning assembly includes at least two drill rod supports installed side by side on the loading platform.

[0014] The technical problem to be solved by the present invention can be further achieved through the following steps: the drill rod bracket includes a socket installed horizontally on the loading platform by bolts, columns installed symmetrically on the socket, and a support plate arranged between the two columns, and the support plate is provided with a number of positioning holes that cooperate with the drill rod.

[0016] The technical problem to be solved by the present invention can be further achieved by the following steps: the four corners of the transport platform are each provided with hydraulically driven retractable legs.

[0017] Compared with the existing technology, the beneficial effects of the present invention are: by integrating the power module, the load-bearing module and the water supply module into one, it not only meets the basic needs of the power station, but also effectively reduces the overall volume of the drilling rig host, greatly improving the maneuverability of the overall crawler tunnel drilling rig; by being equipped with a crawler assembly that is driven solely by the drive module, the present invention can easily follow the host and move forward without the need for manual transportation of the power station, which greatly improves the overall safety and construction efficiency of the project and effectively reduces the economic cost of the project.
