For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0031] The present utility model will be further described in detail below in conjunction with the specification drawings and specific embodiments.

[0032] Figures 1 to 8 An embodiment of the gutter cable trough formwork device of the present utility model is shown. The gutter cable trough formwork device of this embodiment includes a trolley 1 and multiple groups of gutter formwork assemblies 2 (specifically 3 groups, and of course, it can be adjusted in other embodiments). Reinforcing gantry frames 3 that can be docked with the trolley 1 are provided at both ends of the gutter formwork assemblies 2. Transverse movement mechanisms 4 for driving the gutter formwork assemblies 2 to move horizontally and lifting mechanisms 5 for driving the gutter formwork assemblies 2 to lift are provided on both sides of the reinforcing gantry frames 3. Among them, the front-back direction is the length direction of the tunnel, the horizontal direction is the width direction of the tunnel or the left-right direction, and the vertical direction is the height direction of the tunnel or the up-down direction.

[0033] For the gutter cable trough formwork device of this embodiment, the trolley 1 can drive each group of gutter formwork assemblies 2 to be in place successively through the reinforcing gantry frames 3. The transverse movement mechanisms 4 on the reinforcing gantry frames 3 are used to adjust the horizontal positions of the gutter formwork assemblies 2, and the lifting mechanisms 5 are used to adjust the heights of the gutter formwork assemblies 2. After the front-back positions, horizontal positions, and heights of the gutter formwork assemblies 2 are determined, the gutter formwork assemblies 2 are fixed, and concrete is poured after all the formwork assemblies 2 are installed. After the concrete solidifies, the formwork of the gutter formwork assemblies 2 is removed. The lifting mechanisms 5 lift the gutter formwork assemblies 2 to demold. The trolley 1 is docked with the reinforcing gantry frames 3, and then the gutter formwork assemblies 2 are moved to the next construction section. In this way, the construction efficiency can be effectively improved and the construction cost can be reduced.

[0034] Further, in this embodiment, the groove formwork assembly 2 is provided with multiple sets of shaping mechanisms 6 along the length direction. The shaping mechanism 6 includes a first cross beam 61 and a second cross beam 62. A formwork retraction driving member 63 or a fixed connecting member 64 is provided between the first cross beam 61 and the second cross beam 62 (specifically refer to Figure 2 , there are a total of 7 sets of shaping mechanisms 6, 3 sets are provided with formwork retraction driving members 63, 4 sets are provided with fixed connecting members 64, and the two types of shaping mechanisms 6 are alternately distributed. The shaping mechanisms 6 with formwork retraction driving members 63 at both ends are arranged in one-to-one correspondence with the reinforcing gantry frames 3 at both ends). The groove formwork assembly 2 includes multiple groove formworks 21 arranged transversely (specifically refer to Figure 1 and Figure 5 , there are a total of 3 groove formworks 21, which can be water channel formworks and / or cable trench formworks). One side of each groove formwork 21 is hinged to the first cross beam 61, and the other side of each groove formwork 21 is hinged to the second cross beam 62. Among them, the formwork retraction driving member 63 can be, for example, an oil cylinder, a cylinder or an electric push rod, etc. By driving the first cross beam 61 and the second cross beam 62 to move relatively transversely, the two sides of each groove formwork 21 are made to approach each other, realizing formwork retraction, which is convenient for subsequent demoulding; the fixed connecting member 64 can be, for example, a rod, a plate or a fastener such as a bolt, etc. By keeping the first cross beam 61 and the second cross beam 62 fixed, it is avoided that the two sides of the groove formwork 21 approach each other after being squeezed during the concrete pouring process, so that the groove formwork 21 maintains the designed shape and size. Of course, during the concrete pouring process, the formwork retraction driving member 63 also plays a role in keeping the groove formwork 21 in the designed shape and size to a certain extent. Before the formwork retraction driving member 63 retracts the formwork after the concrete solidifies, the fixed connecting member 64 needs to be disassembled first to avoid obstruction.

[0035] Furthermore, in this embodiment, the transverse movement mechanism 4 includes a transverse movement track 41 provided on the reinforcing gantry frame 3, a transverse movement seat 42 provided on the transverse movement track 41, and a transverse movement driving member 43 connected to the transverse movement seat 42. The lifting mechanism 5 is provided on the transverse movement seat 42, and the first cross beam 61 or the second cross beam 62 is connected to the lifting mechanism 5. Among them, the transverse movement driving member 43 and the lifting mechanism 5 can be, for example, an oil cylinder, a cylinder or an electric push rod, etc., and can be installed on the transverse movement track 41 or on the reinforcing gantry frame 3. During use, the transverse movement driving member 43 drives the transverse movement seat 42 to move along the transverse movement track 41, and the transverse movement seat 42 simultaneously drives the lifting mechanism 5 and the groove formwork assembly 2 to move transversely, with a simple and reliable structure. Of course, in other embodiments, the lifting mechanism 5 can also be provided on the reinforcing gantry frame 3, the transverse movement mechanism 4 can be provided on the lifting mechanism 5, and the first cross beam 61 or the second cross beam 62 is connected to the transverse movement mechanism 4, and the transverse position and height of the groove formwork assembly 2 can also be adjusted.

[0036] Further, in this embodiment, a plurality of template vertical fixing rods 51 are provided on the transverse moving seat 42. The plurality of template vertical fixing rods 51 are arranged in one-to-one correspondence with the plurality of groove templates 21. Two connecting rods 52 are hinged to the lower end of the template vertical fixing rod 51. One of the connecting rods 52 is hinged to one side of the groove template 21, and the other connecting rod 52 is hinged to the other side of the groove template 21. After the transverse position and height of the groove template 21 are in place, the overall height of the groove template 21 is fixed by using the template vertical fixing rod 51 and the two connecting rods 52, avoiding the upward movement of the groove template 21 during concrete pouring. The structure is simple and reliable. Before the lifting mechanism 5 lifts the groove template assembly 2 upward, it is necessary to disassemble the template vertical fixing rod 51 and / or the two connecting rods 52 to avoid obstruction.

[0037] As a preferred embodiment, the length of the template vertical fixing rod 51 is adjustable, which is more convenient and flexible to use, and avoids preparing a variety of template vertical fixing rods 51 with different lengths. Among them, the template vertical fixing rod 51 can be formed by connecting a sleeve with internal threads and a rod with external threads at both ends of the sleeve. The length adjustment is achieved by the relative rotation of the sleeve and the rod, or by sleeving two or more hollow rods, and the length adjustment is achieved by aligning the jacks at different positions and inserting pins to lock them.

[0038] As a preferred embodiment, the gutter cable trough template device further includes a vertical wall template 7, and the vertical wall template 7 is connected to the transverse moving seat 42. When the transverse moving seat 42 moves along the transverse moving track 41, it drives the vertical wall template 7 to move transversely, so that the vertical wall template 7 is in place transversely.

[0039] Further, in this embodiment, a template transverse fixing rod 71 is provided between the vertical wall template 7 and the groove template 21. The template transverse fixing rod 71 can be used to fix the transverse relative position between the vertical wall template 7 and the groove template 21, avoiding displacement during concrete pouring.

[0040] Furthermore, in this embodiment, a reinforcement platform 72 is provided between the bottoms of the vertical wall templates 7 on both sides, and a vertical wall template fixing rod 73 is provided on the reinforcement platform 72. The transverse position of the vertical wall template 7 is fixed from the left and right sides by the template transverse fixing rod 71 and the vertical wall template fixing rod 73. The acting forces on both sides of the reinforcement platform 72 can cancel each other out. The structure is simple and reliable, and the reinforcement platform 72 is located at the bottom of the vertical wall template 7 and does not affect traffic. For details, see Figure 8 , before the lifting mechanism 5 lifts the groove template assembly 2 upward, it is necessary to disassemble the template transverse fixing rod 71 and the vertical wall template fixing rod 73 to avoid obstruction.

[0041] As a preferred embodiment, the lengths of the template horizontal fixing rod 71 and the vertical wall template fixing rod 73 are adjustable, which is more convenient and flexible to use and avoids preparing template horizontal fixing rods 71 and vertical wall template fixing rods 73 of various different lengths. Among them, the template horizontal fixing rod 71 and the vertical wall template fixing rod 73 can be formed by connecting a sleeve with internal threads and a rod with external threads at both ends of the sleeve. The length adjustment is achieved by the relative rotation of the sleeve and the rod, or by sleeving two or more hollow rods on each other, and the length adjustment is achieved by aligning the jack holes at different positions and inserting pins to lock them, etc., which will not be elaborated here.

[0042] Further, in this embodiment, a jacking driving member 31 is provided on the upper part of the reinforcement gantry 3, and a gantry fixing cross beam 32 is provided on the jacking driving member 31. Among them, the jacking driving member 31 can be, for example, an oil cylinder, a pneumatic cylinder or an electric push rod, etc. After the reinforcement gantry 3 is positioned in the front-rear direction, the jacking driving member 31 jacks the gantry fixing cross beam 32 upward so that the gantry fixing cross beam 32 abuts against the top of the tunnel, thereby preventing the reinforcement gantry 3 from moving upward during concrete pouring. The structure is simple and the reliability is good.

[0043] The working principle of the trench cable trough template device of the present utility model is as follows:

[0044] As Figure 5 shown, the trolley 1 is used to push the reinforcement gantry 3 to be positioned front and rear, the transverse movement driving member 43 drives the transverse movement seat 42 to move along the transverse movement track 41, and the transverse movement seat 42 simultaneously drives the lifting mechanism 5, the trench template assembly 2, and the vertical wall template 7 to move horizontally into position. The lifting mechanism 5 drives the trench template assembly 2 to descend into position, and then the first cross beam 61 and the second cross beam 62 are fixedly connected by using the fixing connecting member 64 to ensure the cross-sectional shape and size of the trench template 21. The height of the trench template 21 is fixed by using the template vertical fixing rod 51 and two connecting rods 52, and the transverse position of the vertical wall template 7 is fixed by using the template horizontal fixing rod 71 and the vertical wall template fixing rod 73. The jacking driving member 31 jacks the gantry fixing cross beam 32 upward so that the gantry fixing cross beam 32 abuts against the top of the tunnel, thereby fixing the position of the reinforcement gantry 3;

[0045] As Figure 6 shown, after the fixing of the trench template 21 and the vertical wall template 7, etc. is completed, concrete is poured;

[0046] As Figure 7 and Figure 9 shown, after the concrete solidifies, the trolley 1 is connected to the reinforcement gantry 3, the fixing connecting member 64, the template vertical fixing rod 51 and / or two connecting rods 52, the template horizontal fixing rod 71, and the vertical wall template fixing rod 73 are disassembled, and then the formwork closing driving member 63 drives the first cross beam 61 and the second cross beam 62 to move relatively transversely, so that the two sides of each trench template 21 move closer to the middle to achieve formwork closing;

[0047] AsFigure 8 As shown, the lifting mechanism 5 drives the groove formwork assembly 2 to rise and demold, the jacking driving member 31 drives the gantry fixed cross beam 32 to descend and separate from the tunnel top, and then the trolley 1 pushes the reinforcement gantry 3 to drive the groove formwork assembly 2 to move to the next construction section, and so on in a cycle.

Any person skilled in the art can make many possible changes and modifications to the technical solution of the present utility model by using the above-disclosed technical content without departing from the scope of the technical solution of the present utility model, or modify it into equivalent embodiments with equivalent changes.
