The top of the pairs of uprights are connected by the top crossbeams, and the lower parts are fixed to the two lower longitudinal beams respectively. Two top longitudinal beams are arranged in parallel with the lower longitudinal beams and fixed to the top surface of the top crossbeams. This utility model also includes a lifting and translation mechanism; There are two sets of the lifting and translation mechanism, which are respectively installed at both ends of the frame; The lifting and translating mechanism includes a translating outer frame, an upper support beam, a lower support beam, lifting cylinders, an inner lifting sleeve, an outer lifting sleeve, a translating outer sliding sleeve, and a translating cylinder.

Each end of the upper support beam is connected to the upper end of a lifting cylinder, and the lower ends of the two lifting cylinders are each connected to the upper end of an inner lifting sleeve. The lower end of the inner lifting sleeve is supported on the ground. Each end of the lower support beam is fixed to an outer lifting sleeve, which is slidably fitted outside the corresponding inner lifting sleeve. The translating outer sliding sleeve is slidably fitted into the middle of the lower support beam, with both ends connected to the corresponding translating outer frame. One end of each of the two translating cylinders is connected to the outer translating sleeve, and the other end is connected to both ends of the lower support beam.

[0005] Preferably, the present invention also includes a crawling mechanism, which includes a pulley seat, a steel support, a sliding locking link and a sliding cylinder. Two pulley seats are slidably mounted on the lower longitudinal beam. The bottom of each pulley seat is connected to a steel support. The sliding locking link is arranged parallel to the lower longitudinal beam and its two ends are respectively connected to the two steel supports. One end of the sliding cylinder is connected to the lower longitudinal beam and the other end is connected to one of the steel supports.

[0006] Preferably, the pulley seat includes an upper pulley, a lower pulley, a side plate, an upper sealing plate, and a lower sealing plate.

[0027] The present invention provides the following embodiments.

[0028] like Figure 1 , Figure 2 As shown, this utility model discloses a lining trolley for construction of a steep slope tunnel, comprising a frame 1, a top template 2, and side templates 3. The top template 2 is installed on the top of the frame 1, and side templates 3 are installed on both sides of the frame 1. The top template 2 is hinged to a side template 3 on each side. The shapes of the top template and side templates are adapted to the cross-sectional shape of the tunnel. like Figure 1 , Figure 3 As shown, the frame 1 includes a lower longitudinal beam 11, uprights 12, a top crossbeam 13, and a top longitudinal beam 14. Two lower longitudinal beams 11 are arranged in parallel. Multiple uprights 12 are arranged in pairs. The top of the pairs of uprights 12 are connected by the top crossbeam 13, and the lower parts are fixed on the two lower longitudinal beams 11 respectively. Two top longitudinal beams 14 are arranged in parallel with the lower longitudinal beams 11 and fixed on the top surface of the top crossbeam 13. like Figure 3 , Figure 4 As shown, this utility model also includes a lifting and translating mechanism 4; There are two sets of the lifting and translation mechanism 4, which are respectively installed at both ends of the frame 1; The lifting and translating mechanism 4 includes a translating outer frame 40, an upper support beam 41, a lower support beam 42, a lifting cylinder 43, a lifting inner sleeve 44, a lifting outer sleeve 45, a translating outer sliding sleeve 46, and a translating cylinder 47. The translating outer frame 40 is fixed to the middle of the columns 12 at both ends of the frame 1 and to the end of the lower longitudinal beam 11. The upper support beam 41 is slidably fitted into the translating outer frame 40 located in the middle of the columns 12, and the lower support beam 42 is slidably fitted into the translating outer frame 40 located at the end of the lower longitudinal beam 11. Each end of the upper support beam 41 is connected to a lifting cylinder 47. The upper end of cylinder 43 is connected, and the lower end of each of the two lifting cylinders 43 is connected to the upper end of a lifting inner sleeve 44. The lower end of the lifting inner sleeve 44 is supported on the ground. A lifting outer sleeve 45 is fixed to each end of the lower support beam 42. The lifting outer sleeve 45 is slidably fitted on the outside of the corresponding lifting inner sleeve 44. The translation outer sleeve 46 is slidably fitted on the middle of the lower support beam 42. Both ends are connected to the corresponding translation outer frame 40. One end of each of the two translation cylinders 47 is connected to the translation outer sleeve 46, and the other end is connected to both ends of the lower support beam 42.

[0029] A vertical reinforcing rod can also be installed between the upper supporting beam 41 and the lower supporting beam 42 to reinforce the structure.

[0030] The lifting and lowering process of the lifting and translating mechanism 4 is as follows: the piston rod of the lifting cylinder 43 extends and lifts the upper support beam 41 upward. The upper support beam 41 lifts the frame 1 together with the template upward through the translation outer frame 40. At the same time, the lower support beam 42 also moves upward. The lifting outer sleeve 45 slides upward along the lifting inner sleeve 44. The piston rod of the lifting cylinder 43 retracts and the upper support beam 41 descends. The frame 1 together with the template and the lower support beam 42 also descends. The lifting outer sleeve 45 slides downward along the lifting inner sleeve 44.

[0031] The translation process of the lifting and translating mechanism 4 includes: 1. The inner sleeve 44 is supported by the lifting mechanism. The four translation cylinders 47 in the two lifting and translation mechanisms 4 move in the same direction, driving the outer sliding sleeve 46 and the outer frame 40 connected to it to slide and translate along the lower support beam 42. The outer frame 40 then drives the lower longitudinal beam 11 and even the entire frame 1 to translate. The outer frame 40 connected to the column 12 slides along the upper support beam 41. In this way, the lateral position of the frame 1 can be adjusted.

[0032] 2. With the frame 1 supported on the ground, the four translation cylinders 47 in the two sets of lifting and translation mechanisms 4 move in the same direction, causing the lower support beam 42 to slide and translate in the translation outer frame 40, which in turn causes the lifting outer sleeve, lifting inner sleeve, lifting cylinder, and upper support beam 41 to move laterally at the same time. In this way, the lateral position of the lifting and translation mechanism 4 itself can be adjusted.

[0033] 3. The inner sleeve 44 is lifted and supported on the ground. The two sets of lifting and translation mechanisms 4 are translated a small distance in the opposite direction by the translation cylinder 47, such as a few centimeters. This will cause the frame 1 to deflect at a certain angle. There is a gap between the translation outer frame 40 and the upper support beam 41 and the lower support beam 42, which can achieve such a small angle of deflection. Then the inner sleeve 44 is lifted and the frame 1 is supported on the ground. After the translation cylinder 47 is reset, the entire utility model will have a certain angle of deflection. Each time the lining is completed and the next work position is reached, the above steps are repeated to deflect. The utility model can achieve self-turning with a large turning radius. If the turning radius is small, the length of the utility model can be shortened or the deflection angle can be increased at one time to achieve the turning. During the turning process, the side template 3 needs to be retracted. If interference still occurs, the side template 3 needs to be disassembled.

[0034] like Figure 2 , Figure 3 As shown, this utility model also includes a crawling mechanism 5, which includes a pulley seat 51, a steel support 52, a sliding locking link 53, and a sliding cylinder 54. Two pulley seats 51 are slidably mounted on the lower longitudinal beam 11, and a steel support 52 is connected to the bottom of each pulley seat 51. The sliding locking link 53 is arranged parallel to the lower longitudinal beam 11, and its two ends are respectively connected to the two steel supports 52. One end of the sliding cylinder 54 is connected to the lower longitudinal beam 11, and the other end is connected to one of the steel supports 52.

[0035] like Figure 5 , Figure 6 , Figure 7 As shown, the pulley seat 51 includes an upper pulley 511, a lower pulley 512, a side plate 513, an upper sealing plate 514, and a lower sealing plate 515. The two side plates 513 are arranged opposite to each other, with the top connected by the upper sealing plate 514 and the bottom connected by the lower sealing plate 515 and fixed on the steel support 52. One or more upper pulleys 511 are installed on the upper part of the two side plates 513, and one or more lower pulleys 512 are installed on the lower part of the two side plates 513. The lower longitudinal beam 11 is fitted in the space enclosed by the upper pulley 511, the lower pulley 512, and the two side plates 513.

[0036] The longitudinal crawling process of the crawling mechanism 5 is as follows: the inner sleeve 44 is lifted to support the ground, the frame 1 is lifted off the ground, the sliding cylinder 54 drives the sliding locking link 53 and the pulley seat 81 to slide in the forward direction through the steel support 52. After the sliding cylinder 54 is in place, the inner sleeve 44 is retracted, the four steel supports 53 support the ground, the sliding cylinder 54 moves in the direction, and drives the entire frame 1 to slide in the forward direction through the lower longitudinal beam 11. Then the inner sleeve 44 is lifted to support the ground again, and the above process is repeated, thus realizing the longitudinal movement of the entire utility model.

[0037] like Figure 2 , Figure 3As shown, additional columns 48 are provided between the columns 12 at both ends of the frame 1 and the translational outer frame 40. The sides of the additional columns 48 are fixed to the corresponding columns 12, and the translational outer frame 40 is fixed to the corresponding additional columns 48.

[0038] The additional column 48 offsets the lifting and translating mechanism 4 from the side template 3, ensuring that there is no interference with the lifting and translating mechanism 4 when the side template 3 is retracted.

[0039] The bottom of the additional column 48 is fixed to the lower longitudinal beam 11 below. This makes the structure more rationally stressed and stable.

[0040] like Figure 4 As shown, each of the lifting inner sleeves 44 is provided with a support base 49 at its lower end.

[0041] like Figure 2 As shown, walkways 6 are installed on both the upper and lower parts of the frame 1, and ladders 7 are installed on each walkway 6.

[0042] like Figure 1 As shown, between the two columns 12 in pairs, there are reinforcing beams 15 connecting the two columns 12 in the middle and at the bottom, which increases the stability of the frame 1. In addition, additional longitudinal beams can be set on the reinforcing beams 15. When the width is limited, the hydraulic cylinder for the unfolding and retraction of the control side template 3 can be changed from being connected to the column 12 to being connected to the additional longitudinal beam.

[0043] When this utility model is in operation, it reaches the longitudinal position through the crawling mechanism 5, and then moves and centers through the lifting and translating mechanism 4. After the top template 2 is lifted into place, the side templates can be unfolded for lining. After the lining is completed, the side template 3 is retracted to demold the side template 3, and the lifting and translating mechanism 4 is lowered to demold the top template 4. Then, it moves forward to the next work position through the crawling mechanism 5. The above steps are repeated to gradually complete the lining of the entire cavern. If there is a turn in the middle, this utility model can also adjust itself to complete the lining at the same time as completing the turn.

[0044] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
