For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] Figures 1 to 7An embodiment of the utility model of a positioning device for a central water ditch template in a tunnel is shown. The positioning device for a central water ditch template in a tunnel comprises a crossbeam 1, a transverse movement mechanism 2 and a lifting mechanism 3. The two ends of the crossbeam 1 are respectively connected to the inverted arch templates (not shown in the figure) on both sides of the tunnel. The transverse movement mechanism 2 is arranged on the crossbeam 1 to drive the central water ditch template 4 to move horizontally. The lifting mechanism 3 is connected between the transverse movement mechanism 2 and the central water ditch template 4 to drive the central water ditch template 4 to rise and fall relative to the crossbeam 1 (that is, when the lifting mechanism 3 drives the central ditch template 4 to move vertically, the crossbeam 1 will not rise and fall accordingly).

[0028] In the central ditch template positioning device in the tunnel of this embodiment, the crossbeam 1 is connected with the inverted arch templates on both sides, and a transverse movement mechanism 2 is provided on the crossbeam 1, which can drive the central ditch template 4 to move horizontally, and then the horizontal position of the central ditch template 4 can be adjusted separately during the positioning process; the lifting mechanism 3 can drive the central ditch template 4 to rise and fall relative to the crossbeam 1, and then the vertical position of the central ditch template 4 can be adjusted separately during the positioning process, and the connection between the crossbeam 1 and the inverted arch template will not be affected during the adjustment of the vertical position. Through the adjustment of the horizontal position and the vertical position, the precise positioning of the central ditch template 4 can be achieved, which is conducive to ensuring the construction quality. Among them, 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.

[0029] Further, in this embodiment, the lifting mechanism 3 includes a first slide rail 31 arranged vertically, a first slide sleeve 32 sleeved on the first slide rail 31, and a lifting drive 33 driving the first slide rail 31 to lift and lower. The central ditch template 4 is connected to the first slide rail 31, and the first slide sleeve 32 is connected to the transverse mechanism 2. The transverse mechanism 2 includes a second slide sleeve 21 sleeved on the crossbeam 1 and a transverse drive 22 driving the second slide sleeve 21 to move. The first slide sleeve 32 is connected to the second slide sleeve 21. The slide sleeve cooperates with the slide rail to provide a guiding effect, so that the position adjustment of the central ditch template 4 is smoother and the structure is simple, and the use is reliable. Of course, in other embodiments, the slide rail can also be used to cooperate with the guide structure such as the sliding seat, roller, etc. to realize the transverse movement and lifting of the central ditch template 4, and the specific details are not repeated. In this embodiment, the lifting drive 33 and the transverse drive 22 are preferably oil cylinders, which have a simple structure, a large driving force, and are reliable to use. Of course, in other embodiments, electric cylinders, cylinders, servo motors, and other driving components can also be used to drive the central ditch template 4 to move, and the specific details are not repeated.

[0030] As a preferred embodiment, the first sliding sleeve 32 is connected to the second sliding sleeve 21 via a plurality of pins 8. The pins 8 are easy to disassemble, so that the transverse movement mechanism 2 and the lifting mechanism 3 can be easily maintained.

[0031] Furthermore, in this embodiment, the central ditch template 4 includes a U-shaped groove template 41 and reinforcing ribs 42 arranged on the two side walls of the U-shaped groove template 41. A support 43 is provided at the bottom of the U-shaped groove template 41, and one end of the support 43 is connected to the first slide rail 31. When pouring concrete, the concrete on both sides of the central ditch template 4 will exert pressure on it. The reinforcing ribs 42 can strengthen the structural strength of both sides of the U-shaped groove template 41 and effectively prevent it from being deformed due to pressure. Preferably, the support 43 is arranged in the middle of the width direction of the U-shaped groove template 41, so that when the support 43 drives the U-shaped groove template 41 to rise and fall under the driving action of the lifting drive 33, the U-shaped groove template 41 can be prevented from tilting and affecting the final construction quality.

[0032] Furthermore, in this embodiment, the central ditch template positioning device in the tunnel further includes a template vertical locking mechanism 5 for locking the vertical position of the central ditch template 4, and the template vertical locking mechanism 5 is connected to the other end of the support 43 through the connecting seat 6. Specifically, the template vertical locking mechanism 5 includes a third slide rail 51, a third sliding sleeve 52 sleeved on the third slide rail 51, and a lifting locking structure 53 for locking the third sliding sleeve 52, the third sliding sleeve 52 is connected to the connecting seat 6, the locking structure 53 includes a locking pin (not shown in the figure), a first limiting hole 531 and a second limiting hole 532, the third slide rail 51 is provided with a plurality of first limiting holes 531 at intervals along the length direction, the third sliding sleeve 52 is provided with a plurality of second limiting holes 532 at intervals along the length direction, and the locking pin is penetrated through the first limiting hole 531 and the second limiting hole 532. When the lifting drive member 33 drives the central ditch template 4 to rise and fall, the third slide sleeve 52 also rises and falls accordingly. When the position of the central ditch template 4 is determined, the locking pins are inserted into the corresponding first limiting holes 531 and second limiting holes 532. After locking, the third slide rail 51 can bear the weight of the central ditch template 4 together with the crossbeam 1, thereby improving the stability during use. Of course, in other embodiments, a plurality of second limiting holes 532 may be provided on the third slide sleeve 52, and only one first limiting hole 531 may be provided on the third slide rail 51 to cooperate with the locking pin to lock the third slide sleeve 52. Similarly, in other embodiments, only one second limiting hole 532 may be provided on the third slide sleeve 52, and a plurality of first limiting holes 531 may be provided on the third slide rail 51 to cooperate with the locking pin to lock the third slide sleeve 52.

[0033] Furthermore, in the present embodiment, a running wheel 7 is provided at the lower end of the third slide rail 51 to facilitate the central ditch template 4 to move to the next construction area along with the inverted arch template.

[0034] The method of using the central ditch template positioning device in the tunnel of this embodiment is as follows:

[0035] Initially, the template vertical locking mechanism 5 does not lock the vertical position of the center ditch template 4. After the position of the inverted arch template is fixed, the transverse driving member 22 drives the center ditch template 4 to move horizontally, and adjusts the horizontal position to the preset position. The lifting driving member 33 drives the center ditch template 4 to move vertically, and adjusts the vertical position to the preset position. Then, the locking pin is inserted into the corresponding first limit hole 531 and the second limit hole 532 to lock the vertical position of the center ditch template 4. Then, the concrete pouring begins. After the concrete solidifies, the locking pin is removed, and the lifting driving member 33 drives the center ditch template 4 to rise, and the center ditch template 4 is demoulded. Next, the inverted arch templates on both sides of the tunnel are removed, and the center ditch template 4 goes to the next construction area with the inverted arch template. Repeat the above steps until the center ditch pouring operation of all construction sections is completed.

Any technician familiar with the art can use the above disclosed technical content to make many possible changes and modifications to the technical solution of the present invention without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes. Therefore, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention should fall within the scope of protection of the technical solution of the present invention.
