Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] Example
[0028] The utility model will be further described below in conjunction with the accompanying drawings.

[0031] During the construction of the tunnel cable trench formwork, the formwork support frame 2 is slid on both sides of the walking trolley body 1, and the distance between the two formwork support frames 2 is adjusted to adapt to the construction of cable trenches of different widths; the length of the support rod assembly 3 is adjusted and locked to provide support for the top of the formwork support frame 2, thereby improving the stability of the tunnel cable trench formwork.
[0032] Among them, the walking trolley body 1 includes two sets of frames arranged front and back, and the frames include: a main beam 11, a center rod 12 and a frame support rod 13. The center rod 12 is connected to the center of the main beam 11, and two frame support rods 13 are symmetrically arranged on both sides of the center rod 12. The frame support rod 13 is obliquely connected between the main beam 11 and the center rod 12; reinforcing rods are connected between the main beams 11 and the center rods 12 of the two sets of frames.
[0033] The walking trolley body 1 is assembled by splicing steel structures. During assembly, the center rod 12 is first installed at the center of the main beam 11, and the frame support rod 13 is set between the main beam 11 and the center rod 12 to form a group of frames. Then, another group of frames is assembled in the same way, and a reinforcing rod is installed between the two groups of frames to fix the two groups of frames to form the walking trolley body 1. The installation is simple and convenient for assembly at the construction site.
[0034] Wherein, the bottom of the main beam 11 is connected with a running wheel 4. The running wheel 4 can push the running trolley body 1 to walk in the cable trench, which is convenient for the flexible movement of the cable trench template.
[0035] The formwork support frame 2 includes: a transverse adjustment plate 21 and a support plate 22. The transverse adjustment plate 21 is slidably connected to the cavity 14 of the main beam 11. The two transverse adjustment plates 21 are symmetrically arranged on both sides of the main beam 11 and extend out of the main beam 11. The support plate 22 is connected to the extended end of the transverse adjustment plate 21. The support plate 22 is simultaneously connected to the transverse adjustment plates 21 on the same side of the two sets of frames. The support plate 22 connects the transverse adjustment plates 21 of the two sets of frames, expands the area of the support plate 22, and ensures the synchronous action of the formwork support frames 2 in the two sets of frames.
[0036] The support plate 22 is provided with mounting holes 23 for mounting the tunnel cable trench template.
[0037] Among them, a dual-axis motor 15 is arranged in the center of the cavity 14 of the main beam 11, and the two output ends of the dual-axis motor 15 are symmetrically connected with screws 16, and the end of the transverse adjustment plate 21 is provided with a threaded hole 24, and the screw 16 is screwed into the threaded hole 24. The two output ends of the dual-axis motor 15 can drive the screws 16 on both sides to rotate simultaneously, and the screws 16 and the threaded holes 24 of the transverse adjustment plate 21 are threadedly driven to synchronously adjust the extension length of the transverse adjustment plate 21, and then synchronously adjust the spacing of the support plates 22 to adapt to tunnel cable trenches of different widths.
[0038] The support rod assembly 3 includes: an upper support rod 31, a lower support rod 32 and an adjustment tube 33. The top end of the upper support rod 31 is hinged to the side of the support plate 22, and the bottom end of the lower support rod 32 is hinged to the top surface of the main beam 11. The adjustment tube 33 is sleeved on the upper support rod 31 and the lower support rod 32 at the same time without separation. The upper support rod 31, the lower support rod 32 and the adjustment tube 33 are connected to form a complete support rod structure, which can adapt to the position of the support plate 22 to extend or shorten the entire structure when the support plate 22 moves.
[0039] Among them, Figure 4 As shown, both ends of the adjusting tube 33 are provided with conical open ring segments, and the diameter of one end of the open ring segment connected to the main body of the adjusting tube 33 is smaller than the diameter of the other end, and the open ring segment is formed with a plurality of locking springs 34 arranged at intervals.
[0040] A threaded tube 35 is provided at the portion where the adjusting tube 33 and the locking spring piece 34 are connected, and a locking nut 36 is sleeved on the threaded tube 35 .
[0041] The outer wall of the locking nut 36 is evenly provided with anti-slip patterns.
[0042] The locking nut 36 is threadedly connected to the threaded tube 35. The locking nut 36 is rotated to move it toward the end of the locking spring plate 34, thereby generating pressure on the locking spring plate 34, and fastening the locking spring plate 34 to the upper support rod 31 and the lower support rod 32, thereby locking and limiting the upper support rod 31 and the adjusting tube 33, and between the lower support rod 32 and the adjusting tube 33.
[0043] The working principle of the utility model is:
[0044] The tunnel cable trench template walking device provided in this embodiment is first assembled on the construction site during tunnel construction. The specific assembly process is as follows: first, the center rod 12 is installed at the center of the main beam 11, and the frame support rod 13 is set between the main beam 11 and the center rod 12 to form a set of frames. Then, another set of frames is assembled in the same way, and a reinforcing rod is installed between the two sets of frames. The two sets of frames are fixed to form the walking trolley body 1; secondly, according to the width of the tunnel cable trench to be constructed, the dual-axis motor 15 is started to drive the two screw rods 16 to rotate synchronously, and the screw rod 16 is threadedly transmitted with the lateral adjustment plate 21 to make the lateral adjustment plate 21 rotate synchronously. The plate 21 is extended or retracted to adjust the distance between the two support plates 22, and the tunnel cable trench template installed on the support plate 22 is adjusted to a preset width; then, the locking nut 36 is rotated to move toward the end of the locking spring 34, and pressure is applied to the locking nut 36 to reduce the distance between adjacent locking nuts 36, and squeeze the upper support rod 31 and the lower support rod 32, and lock the upper support rod 31 and the adjustment tube 33, and the lower support rod 32 and the adjustment tube 33. At this time, the support rod assembly 3 can provide stable support for the support plate 22; finally, as the construction proceeds, the walking trolley body 1 is pushed to make it move along the cable trench.
[0045] When the width of the tunnel cable trench template needs to be adjusted again, the locking nut 36 is rotated in the opposite direction away from the end of the locking spring 34, so that the locking spring 34 loses pressure and resets, thereby releasing the lock on the upper support rod 31, the lower support rod 32 and the adjustment tube 33. The adjustment tube 33 can slide on the upper support rod 31 and the lower support rod 32 to adapt to the adjustment process.
[0046] The beneficial effects of the utility model are:
[0047] The tunnel cable trench formwork walking device provided in this embodiment can adjust the relative position of the formwork support frame 2 and the walking trolley body 1 during the construction of the tunnel cable trench formwork, adjust the spacing of the tunnel cable trench formwork, and thus adapt to the construction of cable trenches of different widths. It can be reused to reduce construction costs; adjust the length of the support rod assembly 3 and lock it to provide support for the top of the formwork support frame 2, thereby improving the stability of the tunnel cable trench formwork and improving the casting quality of the cable trench.
