Embodiment 1

[0047] Embodiment 1: Operate the device to a designated location. When it is necessary to adjust the overall height of the three-layer platform (the platform on each floor includes the middle platform 10 and the two side platforms 11), open the electric push rod 2 9, and the electric push rod 2 9 drives the hollow square rod 1 2 along the The hollow square rod two 3 moves, the hollow square rod one 2 drives the support rod 1 to move, and the support rod 1 drives the platform mechanism to move, so as to realize the overall height adjustment of the three-layer platform.

[0048] When adjusting the distance between adjacent stands, take adjusting the distance between two stands on the upper side as an example, open the corresponding electric push rod one 7, and the electric push rod one 7 drives the upper hollow square rod four 8 along the upper hollow square rod three 6 Move, the upper hollow square rod four 8 drives the middle square rod 5, the middle stand one 10, the two side...

Embodiment 2

[0050] Embodiment 2: Operate the device to a designated location. When needing to adjust the height of the stand mechanism, open the electric push rod 2 9 to realize the height adjustment of the stand mechanism.

[0051] When adjusting the two 26 and 15 distances between the two pedestals on both sides. Take the platform two 26 on both sides of the upper side and the middle platform two 15 as examples, unscrew the two jacking screws 18 on the upper side, turn on the motor 21, the motor 21 drives the screw rod 22 to rotate, and the screw rod 22 drives the lower hollow round rod 20 to move, and the lower side hollow rod 20 moves. The side hollow round rod 20 drives the trapezoidal chute 19 to move, the trapezoidal chute 19 drives the upper side hollow round rod 20 to move along the upper side round bar 24, the trapezoidal chute 19 drives the trapezoidal slider 28 to move, and the trapezoidal slider 28 drives the round bar The second 27 moves along the chute 17, the round bar tw...

Abstract

The invention discloses a tunneling trolley, and relates to the field of supporting equipment. The tunneling trolley comprises a main frame and is characterized in that the main frame is fixedly connected with second symmetrical hollow square rods, first hollow square rods are correspondingly arranged in the second symmetrical hollow square rods, and second electric push rods are correspondingly arranged in the second symmetrical hollow square rods; and the second symmetrical electric push rods are correspondingly arranged in the first corresponding hollow square rods, the second symmetrical electric push rods are fixedly correspondingly connected with the second corresponding hollow square rods, the push rod ends of the second symmetrical electric push rods are fixedly connected with the first corresponding hollow square rods correspondingly, the first symmetrical hollow square rods are fixedly connected with supporting rods correspondingly, and the supporting rods are fixedly connected with a rack mechanism. According to the technical problem, the tunneling trolley is convenient for tunnel construction.

Description

technical field [0001] The invention relates to the field of support equipment, in particular to a driving trolley. Background technique [0002] The drill and blast method has strong adaptability to geological conditions and low excavation cost, and is especially suitable for the construction of hard rock tunnels, broken rock tunnels and a large number of short tunnels. Therefore, the drill and blast method is still a commonly used tunnel excavation method at home and abroad. [0003] During the tunnel excavation process, it is necessary to carry out road repairs on the tunnel excavation surface, build a platform, and use jackhammers to drill holes on the built platform. A working cycle includes drilling - blasting - slag removal - road repair - platform building - blasting surface shotcrete - drilling, such a working cycle takes about 4 hours. [0004] The jackhammers are placed on a well-built workbench. On a simple platform, the staff have a certain risk of falling and ...
