[0018] A self-propelled device for a tunneling engineering drill jumbo, as Figures 1 to 2 shown, includes four sets of moving mechanisms 1, four driving devices 2 and a controller. The four sets of the moving mechanisms 1 are fixed on the lower cross beam 3 at the four corners of the drill jumbo. The four sets of the driving devices 2 are fixed on the lower cross beam 3 of the drill jumbo. The driving device 2 drives the moving mechanism 1 to move back and forth through a transmission chain. The controller is electrically connected to the four driving devices 2 and is used to control the four driving devices 2 to synchronously drive the moving mechanism to move.

[0019] In a tunneling project constructed by the blasting method, a drill jumbo is an essential self-made device, especially for the excavation of large-section tunnels. The tunnel section is a 10*10m horseshoe-shaped section, which is divided into four steps of scaffolds and weighs up to 16t. During the construction process, the drill jumbo will be moved frequently, which requires large-scale mechanical equipment to cooperate, resulting in low construction efficiency. The utility model installs moving mechanisms at the four corners under the drill jumbo and uses driving devices to drive synchronously, solving the problem that the large-volume and heavy drill jumbo can move back and forth in the tunnel. It has the advantages of simple structure, easy processing and installation, and improved construction efficiency.

[0020] Furthermore, as Figures 1 to 2 shown, the moving mechanism 1 includes a wheel axle 4, two wheels 5, a sprocket and a set of bearings. The set of bearings is fixed on the lower cross beam 3 of the drill jumbo. The wheel axle 4 is fixedly connected with the set of bearings by interference fit. The two wheels 5 are respectively fixedly connected to both ends of the wheel axle. The sprocket is sleeved and welded to the wheel axle. The four moving mechanisms are symmetrically arranged on the lower cross beam at the four corners of the bottom surface of the drill jumbo. Each moving mechanism has the same structure. It is a sprocket sleeved and fixed on the wheel axle 4. The driving device drives the sprocket to rotate. The sprocket drives the wheel axle 4 to rotate. Both ends of the wheel axle 4 are fixedly connected with two wheels. The wheel axle 4 drives the two wheels to rotate, thereby driving the drill jumbo arranged on the moving mechanism to move.

[0021] Furthermore, as Figures 1 to 2As shown, two through holes are symmetrically arranged on the lower cross beam 3 of the drill-blasting jumbo. The complete set of bearings includes a steel pipe sleeve and bearings. The steel pipe sleeve is arranged between the two through holes, and both ends of the steel pipe sleeve are fixedly connected to the inner rings of the two through holes by welding. The bearings are fixedly connected to the steel pipe sleeve by interference fit. The lower cross beam 3 of the drill-blasting jumbo is fixedly connected to the axle 4 through the complete set of bearings. Connecting the axle 4 and the drill-blasting jumbo through the complete set of bearings is a typical connection method for static and dynamic connections. Using the complete set of bearings has both the functions of static and dynamic connections and the advantages of a simple structure.

[0022] Furthermore, as Figures 1 to 2 shown, the axle 4 passes through the steel pipe sleeve and the bearings, and the axle 4 is fixedly connected to the bearings by interference fit. The wheel 5 includes a hub, a rubber tire and a flange. The rubber tire is sleeved on the outer circumference of the hub, and the flange is sleeved in the middle of the hub and fixedly connected to the hub by high-strength bolts. The flange is fixedly connected to one end of the axle by welding.

[0023] Furthermore, as Figures 1 to 2 shown, the driving device 2 is a synchronous motor. The output wheel of the synchronous driving motor is movably connected to the sprocket through a transmission chain. The synchronous motor is fixed to the lower cross beam of the drill-blasting jumbo by bolts. The four synchronous motors are respectively electrically connected to the controller. The synchronous motor is selected as the driving device to synchronously drive the four moving mechanisms to move forward and backward synchronously, eliminating the structure of the synchronous shaft and being easy to install. The four synchronous motors are electrically connected to the controller, and the operator can use the controller to control the four synchronous motors to be turned on and off simultaneously, so as to control the moving mechanisms to move forward or backward synchronously. The output wheel of the synchronous motor and the sprocket are at the upper and lower ends of the oval transmission chain. The synchronous motor drives the output wheel to rotate. The output wheel drives the sprocket to rotate through the transmission chain. The rotation of the sprocket drives the axle to rotate. The rotation of the axle drives the wheels at both ends to rotate, so as to drive the drill-blasting jumbo to move forward and backward.
