[0002] The traditional culvert construction method generally uses scaffolding support and combined formwork for casting. Although this method is simple in technology, due to the relatively small area of ​​a single formwork, the large number of joints in the combined formwork, the high requirements for adjusting the plates and the difficulty in positioning, the difficulty in mastering the flatness, the wall lines are often not straight, the vertical and horizontal joints of the formwork are not properly processed, the surface finish is not high, and there are appearance quality problems such as surface scratches. In addition, it leads to a long construction period. The traditional construction method is time-consuming to erect the formwork, dismantle the support and formwork, and the turnover cycle of the formwork is long, and the investment is relatively large. In view of the actual situation of many culverts and tight construction period in this contract section, there is an urgent need for a culvert trolley that is easy to operate, can form the cross-section in one go, and can move the combined steel formwork as a whole.

[0003] Moreover, most of the current formwork is a single piece of steel, which is small in area and heavy in weight, and requires multiple formwork to be combined. However, there will be gaps between the formworks. Therefore, after demolding, the surface finish of the culvert wall is not high, and there are appearance quality problems such as surface scratches. When the existing equipment encounters culverts of different widths, it is necessary to weld and lengthen the beam. Utility Model Content

DETAILED DESCRIPTION

[0022] The present invention will be further described in detail below through specific embodiments. The following embodiments are merely descriptive and not restrictive, and the protection scope of the present invention cannot be limited by them.

[0023] A culvert integral high-efficiency casting trolley comprises a track 1, the top of which is slidably connected with a trolley hydraulic travel mechanism 2, the top of which is provided with a bottom beam 3, the top of which is provided with a gantry 1 4, the right side of which is provided with a gantry 1 41, the gantry 1 4 and the gantry 2 41 are connected via a connecting beam 42, the outer edge of the gantry 1 4 is fixedly equipped with a translation mechanism 8, the end of the translation mechanism 8 away from the gantry 1 4 is provided with an inner mold 9, the outer side of the inner mold 9 is provided with an outer mold 10, the gantry 1 4 is connected with the gantry 2 41 by means of a connecting beam 42, the length of the connecting beam 42 can be adjusted, compared with traditional beams which are all fixed in size, when encountering culverts of different widths, the beams need to be welded and lengthened, the connecting beam 42 can be adjusted in length according to the width of the culvert, thereby improving the flexibility and assembly speed of the device.

[0024] A support beam 5 is installed on the inner wall of the door frame 4, a support plate 6 is installed on the top of the support beam 5, and a staircase 7 is fixedly installed on the inner wall of the support plate 6. By setting the staircase 7 and the support plate 6, workers can climb up to the support plate 6 through the staircase 7 to carry out construction work.

[0025] A main beam 11 is installed on the top of the gantry 4, and a vertical cylinder 12 is installed at the bottom of the main beam 11. There are four groups of vertical cylinders 12, and each group has two. The vertical cylinders 12 are respectively located at the four corners of the main beam 11. By using the setting of the vertical cylinders 12, the vertical cylinders 12 can lift the inner mold 9 and the outer mold 10, so that the bottom of the inner mold 9 and the outer mold 10 will not contact the ground, which is convenient for the movement of the trolley.

[0026] The inner mold 9 and the outer mold 10 are made of seamless plastic steel formwork. The sizes of the inner mold 9 and the outer mold 10 are 5x6m and 6x6m respectively. The large seamless plastic steel formwork makes the wall of the culvert smoother after demoulding, so that the surface of the culvert does not need to be processed again, which greatly saves the construction period. At the same time, the material of the seam plastic steel formwork is lighter, which makes the weight of the trolley smaller, and the vertical cylinder 11 can lift the plastic steel formwork more easily.

[0027] The translation mechanism 8 includes a connecting block 801, the inner wall of which is fixedly equipped with a connecting rod 802, the outer edge of which is movably sleeved with a translation cylinder 803, the end of the translation cylinder 803 away from the connecting block 801 being movably sleeved with a connecting rod 804, the outer edge of the connecting rod 804 being fixedly equipped with a connecting block 805, the outer wall of the connecting block 805 being installed on the outer edge of the inner mold 9, and by connecting the translation cylinder 803 to the connecting block 801 and the connecting block 805, when the vertical cylinder 11 lifts the plastic-steel formwork, the two ends of the translation cylinder 803 can rotate around the connecting rod 802 on the connecting block 801 and the connecting rod 804 on the connecting block 805, so that the translation cylinder 803 will not be damaged.

[0028] There are several translation mechanisms 8, which are connected to the hydraulic system through pipelines. The trolley hydraulic walking mechanism 2 is connected to the hydraulic system through pipelines. The translation mechanism 8 and the trolley hydraulic walking mechanism 2 are controlled by the hydraulic system, so that multiple translation mechanisms 8 can be extended and retracted at the same time, making the inner mold 9 and demolding faster.

[0029] The connecting beam 42 includes a fixed beam 421, and a telescopic rod 1 422 is movably sleeved on the inner wall of one end of the fixed beam 421, and a telescopic rod 2 423 is movably sleeved on the inner wall of the other end of the fixed beam 421. The outer walls of the fixed beam 421, the telescopic rod 1 422 and the telescopic rod 2 423 are provided with fixing holes 424, and the inner walls of the fixing holes 424 are installed with fixing bolts 425. By pulling the telescopic rod 1 422 and the telescopic rod 2 423 out of the fixed beam 421, the overall length of the connecting beam 42 is lengthened, and by putting the telescopic rod 1 422 and the telescopic rod 2 423 into the fixed beam 421, the overall length of the connecting beam 42 is shortened, and then the fixing bolts 425 can be used to fix it.

[0030] Working principle: when in use, first determine the width of the culvert, then pull out the telescopic rod 1 422 and the telescopic rod 2 423 from the fixed beam 421, and then fix them with the fixing bolts 425, then install the trolley hydraulic walking mechanism 2 under the door frame 1 4 and the door frame 2 41, then lift the assembled door frame 1 4 and the door frame 2 41, then install the door frame 1 4 and the door frame 2 41 on the connecting beam 42, then install the vertical cylinder 12 on the main beam 11, then install the main beam 11 on the door frame 1 4 and the door frame 2 41, and then install the main beam 11 on the door frame 1 4 and the door frame 2 41. The crane lifts the inner mold 9 and the outer mold 10, fixes the inner mold 9 and the outer mold 10, connects the inner mold 9 to the vertical cylinder 12, and then connects the translation mechanism 8 between the door frame 1 4 and the door frame 2 41. At this time, the entire trolley is installed. After the concrete is formed, the inner mold 9 and the outer mold 10 are separated, and then the inner mold 9 and the outer mold 10 are separated from the concrete. Subsequently, the inner mold 9 and the outer mold 10 are lifted by the vertical cylinder 12, and the trolley hydraulic walking mechanism 2 is used to walk on the track 1, so that the entire device is moved to the next stage of construction for pouring.
