Detailed Description

The present application is described in further detail below with reference to fig. 1.

The embodiment of the application discloses cast-in-place bridge tuyere construction trolley. Referring to fig. 1, a construction vehicle is included, and the construction vehicle includes a first frame 1, a second frame 2, and a third frame 3. Wherein, first frame 1 and second frame 2 parallel arrangement, second frame 2 are fixed between the one end of first frame 1 and third frame 3, and the equal fixedly connected with side frame 4 in both ends of second frame 2, side frame 4 is fixed between the side of first frame 1, third frame 3. Thus, after the construction vehicle is installed on the side surface of the bridge 15, a relatively closed space is formed between the construction vehicle and the side surface of the bridge 15, so that construction and installation are improved.

One side of the first frame 1 close to the third frame 3 is provided with a first walking mechanism 5, and one end of the third frame 3 far away from the second frame 2 is provided with a second walking mechanism 6. The length of the first frame 1 is greater than that of the third frame 3, one end of the first frame 1, which is far away from the second frame 2, is connected with a counter-pulling member 7, and the counter-pulling member 7 is used for being connected with a bridge 15. During construction, the construction vehicle is hoisted to the tuyere to be constructed, so that the first traveling mechanism 5 is in contact with the bridge deck of the bridge 15, the second traveling mechanism 6 is in contact with the side face of the bridge deck, and a space for construction personnel to move is limited by the construction vehicle and the side face of the bridge 15. The construction vehicle is then fixed to the bridge 15 by means of the counter-pulling elements 7, so that the first frame 1 can bear the weight of the entire construction vehicle and the construction personnel, since the length of the first frame 1 is greater than the length of the third frame 3.

Specifically, the first traveling mechanism 5 and the second traveling mechanism 6 have the same structure and are both provided as rollers. Wherein a guide rail 8 is laid on the deck of the bridge 15, and the first travel mechanism 5 slides in the guide rail 8. The guide rail 8 provides a predetermined moving track for the first traveling mechanism 5 so as to prevent the construction vehicle from shaking during the moving process.

The counter-pulling member 7 comprises a fixing strip 71, the fixing strip 71 is laid along the length direction of the bridge 15, one side of the fixing strip 71 is fixedly connected with a fixing plate 72, the fixing plate 72 is horizontally arranged, and the length of the fixing plate 72 is equal to that of the fixing strip 71. The fixed plate 72 is connected with an adjusting part 73, a fixed part is embedded in the bridge surface of the bridge 15, and the adjusting part 73 is detachably connected with the fixed part.

Specifically, the adjusting member 73 includes an adjusting bolt 731, an upper end of the adjusting bolt 731 is connected to an adjusting nut 732, and a lower end of the adjusting bolt 731 penetrates the fixing plate 72. The fixing member is a fixing pipe 74 buried in the deck of the bridge 15, the fixing pipe 74 is provided with internal threads, and the adjusting bolt 731 is in threaded connection with the fixing pipe 74. The adjusting bolts 731 and the fixing tubes 74 are provided in plural groups and spaced side by side to enhance the counter-pulling force to the construction vehicle.

One side of the fixing strip 71, which is far away from the fixing plate 72, is provided with a dovetail groove 9, and the dovetail groove 9 is arranged along the length direction of the fixing strip 71 and penetrates through two ends of the fixing strip 71. One end of the first frame 1, which is far away from the second frame 2, is fixedly connected with a connecting strip 10, the shape of the cross section of the connecting strip 10 is matched with the shape of the cross section of the dovetail groove 9, and the connecting strip 10 is connected with the dovetail groove 9 in a sliding mode. The connecting bar 10 is locked with the fixing bar 71 by bolts.

When the construction vehicle needs to be moved, the bolts between the connecting bars 10 and the fixing bars 71 are removed, then the fixing bars 71 are continuously connected in the advancing direction of the construction vehicle, and then the construction vehicle is dragged to advance on the bridge floor by using a trailer. Because the former reverse-pulling component 7 continuously provides tensile force for the construction vehicle in the moving process of the construction vehicle, the construction vehicle cannot incline towards one side, and the trailer can drag the construction vehicle.

The first frame 1 is also connected with a plurality of supporting screw rods 11, the supporting screw rods 11 are perpendicular to the first frame 1 and are in threaded connection with the first frame 1, and the supporting screw rods 11 are connected with matched nuts. In the embodiment of the present application, two support screws 11 are provided, and the two support screws are arranged side by side at intervals along the moving direction of the first frame 1. When the construction vehicle is mounted on the bridge 15, the projection of the support screw 11 in the horizontal plane is located on the deck of the bridge 15 and adjacent to the side of the bridge 15. After the construction vehicle is connected with the reverse-pulling member 7, the support screw 11 is rotated to make the support screw 11 abut against the bridge floor, and then the support screw 11 is locked with the first frame 1 by using a nut. The presence of the supporting screw 11 is able to withstand a portion of the pressure, so that the first travel mechanism 5 is less prone to deformation.

The construction vehicle is also internally provided with a ladder stand which comprises a first ladder stand 12 and a second ladder stand 13. Specifically, a walking platform 14 is fixedly connected to the middle of the second frame 2, the walking platform 14 is fixed between the two side frames 4, the first ladder stand 12 is fixed between the upper surface of the walking platform 14 and the first frame 1, and the second ladder stand 13 is fixed between the lower surface of the walking platform 14 and the third frame 3. The first ladder stand 12 and the second ladder stand 13 are obliquely arranged and form a V-shaped structure so as to construct a tuyere structure of a bridge 15.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
