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.

Example Embodiment

[0047] Example a: operation of the present apparatus to the specified location. When the need to adjust the overall height of the three-stage (each intermediate carriage includes a carriage 10 and a carriage 11 on both sides), to open the two electric push rod 9, 9 drive the two electric push rod a hollow square bar 2 along two hollow square rod 3 is moved, a hollow square bar moving supporting rod 2 drives the supporting rod 1 to drive the carriage moving mechanism, to achieve the overall three stage height adjustment.

[0048] Adjusting the pitch of the adjacent stage in order to adjust the upper side of the two stage spacing, for example, open the corresponding electric push rod 7 a, 7 a motor driven push rod on the side of the hollow square bar 8 along the four sides of the hollow square bars three 6 is moved, four hollow square rod 8 on the side of the intermediate drive shaft 5, a middle stage 10, a stage 11 on both sides, five hollow square rod 12, motor 13 and pusher three hollow square rod adjacent implemented 6:14 the pitch adjustment stage.

[0049] When adjusting the width of each stage, three open the corresponding electric push rod 13, driven by an electric ram three hollow square rod 13 along the hollow square rod 6:14 5:12 movement, hollow square rod 14 driven by six sides of a carriage 11, to achieve each width adjustment stage.

Example Embodiment

[0050] Second Embodiment: The operation of the present apparatus to the specified location. Need to adjust the height of the gantry mechanism to open electric putter two 9, to achieve stand height adjustment mechanism.

[0051] When adjusting two sides of the carriage 26 and intermediate carriage 15 two distance. Both the upper side 26 of the intermediate stage two stage two 15, for example, loosen the upper two top wire 18, opening motor 21, the motor 21 drives rotation of the screw 22, rod 20 moves the lower side of the hollow drive screw 22, under side of the hollow rod 20 to drive the chute 19 moves trapezoidal, trapezoidal chute drive side of the hollow round bar 19 of the circle 20 along a rod 24 moves the chute 19 to drive the trapezoidal slider 28 is moved trapezoidal, trapezoidal slider drive rod 28 27 is moved along the two chute 17, 27 driven by two round rods 27 moving on the two sides of the stage two drive side 26 of the slider 28 along a trapezoidal chute 19 moves trapezoidal, round bar, to achieve two sides of the stage and the intermediate stage 26 2:15 distance adjustment.

[0052] When adjusting two sides of the carriage 26 is formed with a platform intermediate stage two 15, four top wire 18 loosen, open the two motors 21, two sides to achieve simultaneous movement of the stage two 26, the intermediate stage and achieve 15 form a two internet.
