[0029] In order to make the objectives, technical solutions and beneficial effects of the present application clearer, the following will, with reference to the accompanying drawings, elaborate on the preferred embodiments of the present application in detail for the convenience of technicians' understanding.

[0030] Embodiment 1:

[0031] Refer to Figures 1 to 3 , a large drilling and blasting jumbo device facilitating movement, and the large drilling and blasting jumbo device facilitating movement includes:

[0032] A framework 1, welded by four vertical beams 2 and eight cross beams 3. A load-carrying rack 4 is provided at the top of the framework 1, and a fence 5 is provided at the edge of the load-carrying rack 4;

[0033] Wheels 6, rotatably installed at the bottom of the framework 1;

[0034] Wherein, a pair of braking strips 7 are hinged to the bottom of the framework 1 through hinge shafts. When the wheels 6 are in a moving state, the braking strips 7 rotate and fold away from the ground. When the wheels 6 are in a stationary state, the braking strips 7 rotate towards the ground and abut against the ground.

[0035] Specifically, taking Figure 1 and Figure 3 as examples, four vertical beams 2 are symmetrically provided on both sides of the load-carrying rack 4. The four vertical beams 2 are distributed along the axial direction of the tunnel 10. Eight cross beams 3 are perpendicularly welded between the four vertical beams 2. The front lower part of the load-carrying rack 4 is in a hollow state to facilitate technicians or operating equipment to pass through. A cross beam 3 is also installed at a position above the middle of the vertical beam 2 (as shown in Figure 1 ). Diagonal rods 11 are symmetrically provided between the cross beam 3 and the vertical beam 2 to enhance the structural strength. The cross beam 3, the vertical beam 2 and the diagonal rod 11 together form the framework 1; the bottom of the fence 5 is fixedly connected to the top of the framework 1. If the fence 5 is made of a rigid material, the two are fixedly connected by welding. If the fence 5 is made of a material such as a screen or a wooden board, the two are detachably connected and fixed by bolts and nuts. The fence 5 plays a protective role and can prevent technicians from falling from the edge of the load-carrying rack 4, improving its safety. There is a notch on the fence 5, through which technicians can enter the load-carrying rack 4;

[0036] As shown in Figure 2 , the load-carrying rack 4 is welded by several longitudinal rods 12 and cross rods 13. There are four longitudinal rods 12 and four cross rods 13, so that it is convenient for technicians or tools to be placed on the load-carrying rack 4 without falling;

[0037] The wheel 6 is rotatably installed at the bottom of the framework 1. The installation of the wheel is a prior art and will not be further elaborated here. A pair of braking bars 7 are hinged to the bottom of the framework 1 through hinge shafts. There are two hinge shafts, and there is a spacing between the pair of braking bars 7 to prevent mutual influence when they rotate. When the wheel 6 is in a moving state, the braking bars 7 rotate and retract away from the ground to avoid friction with the ground and hinder the movement of the device. When the wheel 6 is in a stationary state, the braking bars 7 rotate towards the ground and abut against the ground. The braking bars 7 generate a large friction with the ground to prevent the device from moving and enhance the stability of the device when it is stationary.

[0038] In this embodiment, the framework 1 of the trolley is mainly welded by four vertical beams 2 and eight cross beams 3. Its structure is simple and its weight is light. A relatively small traction force can be used to drive its movement, thus avoiding the damage and deformation problems caused by a large traction force acting on the drill and blast trolley.

[0039] Embodiment Two:

[0040] See Figures 1 to 3 , based on Embodiment One, optionally, the large drill and blast trolley device facilitating movement further includes a stop block 8, and the stop block 8 is provided with an arc matching the wheel 6.

[0041] Specifically, when the trolley device stops moving, place the stop block 8 outside the wheel 6 so that the arc of the stop block 8 fits against the tire end face of the wheel 6, making them abut against each other. At the same time, the bottom of the stop block 8 abuts against the ground and generates friction to prevent the wheel 6 from moving through this friction.

[0042] In this way, when the trolley device is on a sloped road surface, through the stopping effect of the stop block 8 cooperating with the braking bars 7, the trolley device can be stably parked on this road surface to prevent it from moving.

[0043] Optionally, the stop block 8 is a rubber stop block.

[0044] Specifically, the rubber stop block has a certain flexibility, wear resistance and roughness, and can generate a large friction with the ground, thereby further enhancing the stability of the device when it is stationary.

[0045] Optionally, slides 9 are provided on both sides of the framework 1.

[0046] Specifically, the slides 9 are fixed to the framework 1, and the top of the slides 9 is located below the notch of the fence 5. By providing the slides 9, technicians can load and unload the cargo rack 4 through the slides 9.

[0047] Optionally, the vertical beams 2 and the cross beams 3 are made of 18 I-beams.

[0048] Specifically, the 18 I-beam has high strength. Its cross-sectional shape and material endow it with high bending, torsion and shearing resistance capabilities, enabling it to withstand large pressures and shearing forces. The 18 I-beam has good stability. Its material is uniform, the cutting precision is high, and it has high reliability and stability, and problems such as deformation or fracture are not likely to occur, further avoiding the problem of damage and deformation of the framework 1 when the traction force acts.

[0049] At the same time, the 18 I-beam has a relatively light self-weight, which can reduce the overall weight of the trolley device, further reducing the traction force when the trolley moves. The 18 I-beam is also convenient for on-site processing and installation, greatly shortening the construction period and improving the construction efficiency.

[0050] Optionally, the large drill and blast trolley device that is easy to move is towed by a loader.

[0051] Specifically, the loader can provide sufficient traction force to meet the working condition requirements.

[0052] In summary, the framework 1 of the trolley in the present application is mainly welded by four vertical beams 2 and eight cross beams 3. Its structure is simple and the weight is relatively light. A relatively small traction force can be used to drive its movement, thus avoiding the problem of damage and deformation caused by a large traction force acting on the drill and blast trolley.

[0053] When the trolley device in the present application is on a sloped road surface, through the stopping action of the anti-slip block 8 cooperating with the braking strip 7, the trolley device can be stably parked on this road surface to prevent its movement.

[0054] The anti-slip block 8 in the present application is a rubber anti-slip block. The rubber anti-slip block has certain flexibility, wear resistance and roughness, and can generate a large friction with the ground, thereby further enhancing the stability of the device when it is stationary.

[0055] In the present application, by providing a slideway 9, technicians can load and unload the cargo rack 4 through the slideway 9.

[0056] In the present application, the vertical beam 2 and the cross beam 3 adopt 18 I-beams. The 18 I-beam has high strength. Its cross-sectional shape and material endow it with high bending, torsion and shearing resistance capabilities, enabling it to withstand large pressures and shearing forces. The 18 I-beam has good stability. Its material is uniform, the cutting precision is high, and it has high reliability and stability, and problems such as deformation or fracture are not likely to occur, further avoiding the problem of damage and deformation of the framework 1 when the traction force acts. At the same time, the 18 I-beam has a relatively light self-weight, which can reduce the overall weight of the trolley device, further reducing the traction force when the trolley moves. The 18 I-beam is also convenient for on-site processing and installation, greatly shortening the construction period and improving the construction efficiency.

[0057] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present application and not to limit them. Although the present application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present application; the dimensions of the drawings have nothing to do with the specific physical objects, and the physical object dimensions can be arbitrarily changed.
