Description

Technical Field

[0001] The embodiments of the utility model relate to the technical field of tunnel lining, and in particular to a concrete lining form traveler. Background Art

[0002] The lining form traveler is a special equipment used in the secondary lining of tunnels for lining the inner wall of the tunnel. The emergency stop lane is a small section of space separately opened outside the normal driving road. The emergency stop lane in the tunnel also needs to be lined by the lining form traveler. However, due to the particularly large tunnel section with the emergency stop lane, the ordinary lining form traveler cannot meet the lining requirements.

[0003] In the prior art, the usual practice is to modify the lining form traveler when lining the emergency stop lane to make it larger, and then modify it back to the ordinary lining form traveler after the lining of the emergency stop lane is completed, so as to drive and line in the main tunnel belt. However, the existing method not only wastes time and delays the project progress, but also the temporarily modified lining form traveler may be rough with large errors, which is not conducive to the lining of the emergency stop lane.

[0004] Therefore, how to design a concrete lining form traveler for the emergency stop lane, which can both line the emergency stop lane and move normally in the main tunnel, has become an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0005] To solve the above problems, the embodiments of the utility model provide a concrete lining form traveler for the emergency stop lane, including: a gantry, a top form, side forms, an inner turning form, a form moving unit and a support rod. The support rod is fixedly connected to the gantry and the top form. The side forms and the inner turning form are movably connected and are suitable for turning the inner turning form inward. The form moving unit is detachably connected to the gantry and the inner turning form and is suitable for moving the inner turning form to the designated pouring position.

[0006] Optionally, the transverse distance of the top form is smaller than the transverse distance of the gantry, and the side forms include a plurality of side form units movably connected to each other.

[0007] Optionally, the top form and the side forms are provided with first connection holes for fixedly connecting with each other, and the side forms and the inner turning form are provided with second connection holes for fixedly connecting with each other.

[0009] Optionally, it further includes: a stay bar, and the stay bar is fixedly connected to two adjacent support rods.

[0010] Optionally, it further includes: a main lifting unit, a moving device, a moving bottom column, and a jack bottom column. The main lifting unit, the moving bottom column, and the jack bottom column are fixedly connected to the bottom of the gantry. The moving device is connected to the moving bottom column. The jack bottom column is used for fixedly connecting to a jack. The jack bottom column is longer than the moving bottom column and shorter than the sum of the lengths of the moving bottom column and the moving device.

[0011] Optionally, the gantry is composed of gantry components. The gantry components include a lower longitudinal beam, columns, an upper longitudinal beam, a horizontal support, an inclined support, and an inclined tie rod. The columns are fixedly connected to the lower longitudinal beam and the upper longitudinal beam. The horizontal support is fixedly connected to the upper longitudinal beam. The inclined support is fixedly connected to the lower longitudinal beam and the horizontal support. The inclined tie rod is fixedly connected to the lower longitudinal beam and the columns.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the protection scope of the present utility model.

[0022] Please refer to Figure 1 - Figure 2 , Figure 1 It is a schematic diagram of the shrinkage and movement state of a concrete lining formwork trolley for an emergency parking strip provided by an embodiment of the present utility model; Figure 2 It is a schematic diagram of the lining state of a concrete lining formwork trolley for an emergency parking strip provided by an embodiment of the present utility model. As Figure 1 - Figure 2 shown, an embodiment of the present utility model provides a concrete lining formwork trolley for an emergency parking strip, including: a gantry, a top form 1, a side form 2, an inward turning form 3, a form moving unit 4, and a support rod 5. The support rod 5 is fixedly connected to the gantry and the top form 1. The side form 2 and the inward turning form 3 are movably connected and are suitable for turning the inward turning form 3 inward. The form moving unit 4 is detachably connected to the gantry and the inward turning form 3 and is suitable for moving the inward turning form 3 to the designated pouring position.

[0023] The fixed connection means that the relative positions of the connected components remain unchanged after connection. In some embodiments, the fixed connection includes welding. In other embodiments, the fixed connection can be bolt connection. The movable connection means that the relative positions of the two connected parts can be changed. In some embodiments, the movable connection method includes pin connection. The inward turning of the inward turning form means turning toward the gantry side. The form moving unit can specifically be a telescopic oil cylinder.

[0024] It should be noted that by setting the support rod 5 to support the gantry and the top form, in fact, a smaller gantry is set, so as to leave a space for the inward turning of the inward turning form and a space for the shrinkage of the side form.

[0025] In this way, the form traveler for the emergency parking strip divides the formwork into a top formwork 1, side formworks 2, and an inward-turning formwork 3. The support rod 5 props up the top formwork 1, thus leaving enough inward-turning space for the inward-turning formwork 3. The formwork moving unit 4 is detachable, so that the inward-turning formwork 3 can be inward-turned after the formwork moving unit 4 is detached. After the form traveler for the emergency parking strip completes the lining of the emergency parking strip, the formwork moving unit is detached and the inward-turning formwork is inward-turned, greatly reducing the cross-sectional area of the form traveler. In cooperation with the retractable side formworks 2 connected by movable joints, it can move normally in the main tunnel. After moving to the next emergency parking strip, the inward-turning formwork 3 is outward-turned, the formwork moving unit 4 is installed, and after the inward-turning formwork 3 and the side formworks 2 are moved, lining is carried out, thereby obtaining a form traveler for the emergency parking strip that can both line the emergency parking strip and move normally in the main tunnel.

[0026] Please continue to refer to Figure 1 - Figure 2 , as shown in the figure, in some embodiments, the transverse distance of the top formwork 1 is less than the transverse distance of the gantry, and the side formworks 2 include a plurality of side formwork units that are movably connected to each other.

[0027] As shown in the figure, the transverse distance AB of the top formwork 1 is less than the transverse distance CD of the gantry. The top formwork 1 is fixedly connected to the gantry and cannot be retracted, while the side formworks 2 are movably connected to the top formwork 1 and have the ability to retract. In this way, by reducing the top formwork 1 and increasing the retractable side formworks 2, the retraction ability of the form traveler for the emergency parking strip can be improved.

[0028] By providing a plurality of side formwork units 21 that are movably connected, the side formworks 2 are composed of the side formwork units 21, thereby further increasing the retraction ability. In some embodiments, the side formworks 2 may specifically include two side formwork units 21.

[0029] Please continue to refer to Figure 1 - Figure 2 , as shown in the figure, in some embodiments, the top formwork 1 and the side formworks 2 are provided with first connection holes for fixedly connecting to each other, and the side formworks 2 and the inward-turning formwork 3 are provided with second connection holes for fixedly connecting to each other.

[0030] The first connection holes are used to fixedly connect the top formwork 1 and the side formworks 2 to each other, and the second connection holes are used to fixedly connect the side formworks 2 and the inward-turning formwork 3. Specifically, the first connection holes and the second connection holes can be bolt holes. When the inward-turning formwork moves to the designated pouring position, the top formwork 1 and the side formworks 2 are fixedly connected through the first connection holes, and the side formworks 2 and the inward-turning formwork 3 are fixedly connected through the second connection holes, so that the top formwork 1, the side formworks 2, and the inward-turning formwork 3 are fixed to realize lining. In some embodiments, the fixation of the top formwork 1, the side formworks 2, and the inward-turning formwork 3 can be further strengthened by lead screws to prevent the side formworks 2 or the inward-turning formwork 3 from moving out of position due to excessive pressure during concrete pouring, affecting the tunnel lining effect.

[0031] It should be noted that when the side form 2 includes a plurality of side form units 21, in some embodiments, third connection holes for fixedly connecting to each other are provided between adjacent side form units 21. In this way, by providing the third connection holes to fixedly connect the side form units 21, the side form units 21 can be fixedly connected during lining, making the side form 2 stable enough while improving the shrinkage ability, and ensuring the normal progress of lining.

[0032] Please refer to Figure 3 , Figure 3 is a side view of a concrete lining formwork trolley for an emergency stopping strip provided by an embodiment of the present invention. As Figure 3 shown, in some embodiments, it further includes: a stay 97, and the stay 97 is fixedly connected to two adjacent support rods 5. Specifically, the fixed connection can be a bolt connection. In this way, the support rods 5 can be further fixed to prevent the support rods 5 from deforming when the concrete lining formwork trolley for the emergency stopping strip moves.

[0033] Please combine Figure 3 with Figure 4 , Figure 4 is a schematic diagram of the main track and the emergency stopping strip track provided by an embodiment of the present invention. As shown in the figure, in some embodiments, the concrete lining formwork trolley for the emergency stopping strip further includes: a main lifting unit 6, a moving device 71, a moving bottom column 72, and a jack bottom column 8. The main lifting unit 6, the moving bottom column 72, and the jack bottom column 8 are fixedly connected to the bottom of the gantry. The moving device 71 is connected to the moving bottom column 72. The jack bottom column 8 is used for fixedly connecting to a jack. The jack bottom column 8 is longer than the moving bottom column 72 and shorter than the sum of the lengths of the moving bottom column 72 and the moving device 71.

[0034] The emergency parking bay track is independent of the main track. The concrete lining formwork trolley for the emergency parking bay moves in the main tunnel through the main track and linings the emergency parking bay through the emergency parking bay track. The moving device 71 is connected to the gantry through the moving bottom column 72 and is used to move the concrete lining formwork trolley for the emergency parking bay along the main track or the emergency parking bay track. The main lifting unit 6 is connected to the gantry and is used to lift and lower the concrete lining formwork trolley for the emergency parking bay. On the one hand, when the special trolley for the emergency parking lane moves on the main track and switches to the emergency parking bay track, the main lifting unit 6 extends to touch the ground and further lifts the concrete lining formwork trolley for the emergency parking bay until the moving device 71 leaves the ground, so as to place the switching track for track conversion under the moving device 71. Then, the moving device 71 is rotated to align with the switching track, and the main lifting unit 6 is contracted to place the moving device 71 on the switching track and further contracted until the main lifting unit 6 leaves the ground, so that the concrete lining formwork trolley for the emergency parking bay completes the track change. On the other hand, when lining the emergency parking bay, the main lifting unit 6 extends to touch the ground and further lifts the concrete lining formwork trolley for the emergency parking bay until the moving device 71 leaves the ground, so as to install a jack under the jacking bottom column 8, thereby protecting the moving device 71 during the pouring process.

[0035] Please continue to refer to Figure 1 and Figure 3 , as shown in the figure, in some embodiments, the gantry is composed of gantry components. The gantry components include a lower longitudinal beam 91, a column 92, an upper longitudinal beam 93, a horizontal support 94, an inclined support 95, and an inclined tie rod 96. The column 92 is fixedly connected to the lower longitudinal beam 91 and the upper longitudinal beam 93. The horizontal support 94 is fixedly connected to the upper longitudinal beam 93. The inclined support 95 is fixedly connected to the lower longitudinal beam 91 and the horizontal support 94. The inclined tie rod 95 is fixedly connected to the lower longitudinal beam 91 and the column 92.

[0036] In this way, taking the lower longitudinal beam 91, the column 92, the upper longitudinal beam 93, the horizontal support 94, the inclined support 95, and the inclined tie rod 96 as components and connecting them in a certain way to form a gantry with sufficient support strength, thereby reducing the amount of gantry materials used, reducing the weight of the gantry, making it easier for the main lifting unit 6 to lift the gantry, and making it more convenient to change the track.

[0037] Please continue to refer to Figure 2 , as shown in the figure, in some embodiments, the number of the horizontal supports 94 is an even number, and the gantry components further include a horizontal beam 98. Opposite ends of the horizontal beam 98 are each fixedly connected to a horizontal support 94.

[0038] Specifically, the fixed connection includes bolt connection.

[0039] In this way, the horizontal length of the gantry is adjustable. By matching horizontal beams 38 of different sizes and combining top columns 37 of different lengths, different-sized formworks 1 can be applied while other gantry components remain unchanged.

[0040] Please continue to refer to Figure 1 , as shown in the figure, in some embodiments, it further includes: a ventilation pipe 11, and the ventilation pipe 11 is arranged in the gantry cavity.

[0041] The gantry cavity refers to the unoccupied space in the gantry. In a specific embodiment, the cavity space where the ventilation pipe 11 is arranged includes the space surrounded by the diagonal brace 95, the horizontal brace 94, and the column 92 as shown in the figure.

[0042] In this way, it is avoided that the ventilation pipe is near the formwork, which causes the operator to be unable to approach the inspection window of the formwork for vibrating operations, thereby further improving the lining quality.

[0043] Please continue to refer to Figure 3 , as shown in the figure, in some embodiments, it further includes: a vertical support unit 12. One end of the vertical support unit 12 is pin-connected to the horizontal support 94, and the other end is pin-connected to the side form 2. It should be noted that since the transverse distance AB of the top form 1 is less than the gantry transverse distance CD, during the lining operation, part of the side form 2 will be located directly above the gantry as shown in the figure. In this way, the stability can be further enhanced and the supporting force can be provided.
