Abstract
Description
Technical Field
[0001] The embodiments of the present utility model relate to the technical field of tunnel lining, and particularly to a lining formwork trolley. Background Art
[0002] A lining formwork trolley is a special equipment used in the secondary lining of a tunnel for lining the inner wall of the tunnel. Concrete is injected into the lining formwork trolley and poured into the shape of the tunnel wall, which forms the tunnel wall after condensation. During the pouring process, in order to avoid the generation of bubbles that affect the strength of the tunnel wall due to uneven pouring, the lining formwork trolley is usually vibrated continuously by a vibrating device.
[0003] In order to meet the strength requirements, the existing lining formwork trolleys usually use more materials in construction, which not only increases the construction cost but also increases the weight of the lining formwork trolley, resulting in a high requirement for the vibration force. Therefore, it is easy to cause the situation that the tunnel wall contains bubbles due to insufficient vibration force, or waste a large amount of energy for vibration.
[0004] Therefore, how to reduce the weight of the lining formwork trolley while ensuring the strength has become an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0018] In order to more clearly illustrate the technical solutions in the embodiments of the present application or the prior art, the following will briefly introduce the drawings required for the description of the embodiments or the prior art. Obviously, the drawings in the following description are only the embodiments of the present application. For those of ordinary skill in the art, other drawings can be obtained according to the provided drawings without creative efforts.
[0019] Figure 1It is a cross-sectional view of a concrete lining formwork trolley provided by an embodiment of the present utility model;
[0020] Figure 2 is Figure 1 a side view of the concrete lining formwork trolley shown. Specific embodiments
[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 shall fall within the protection scope of the present utility model.
[0022] Please refer to Figure 1 - Figure 2 , Figure 1 which is a cross-sectional view of a concrete lining formwork trolley provided by an embodiment of the present utility model, Figure 2 is Figure 1 a side view of the concrete lining formwork trolley shown. As Figure 1 - Figure 2 shown, an embodiment of the present utility model provides a concrete lining formwork trolley, including: a form 1, a moving device 2, and a gantry 3. The gantry 3 connects the form 1 and the moving device 2. The gantry 3 is composed of gantry components, and the gantry components include a lower longitudinal beam 31, a column 32, an upper longitudinal beam 33, a horizontal support 34, an inclined support 35, and an inclined tie rod 36. The column 32 is fixedly connected to the lower longitudinal beam 31 and the upper longitudinal beam 33. The horizontal support 34 is fixedly connected to the upper longitudinal beam 33. The inclined support 35 is fixedly connected to the lower longitudinal beam 31 and the horizontal support 34. The inclined tie rod 36 is fixedly connected to the lower longitudinal beam 31 and the column 32.
[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, and the components are connected by welding into an inseparable whole to further strengthen the strength of the gantry. In other embodiments, the fixed connection can be bolt connection, so that the whole gantry is detachable and convenient for transportation.
[0024] The fixedly connected lower longitudinal beam 31, upper longitudinal beam 33, column 32, and horizontal support 34 form a basic gantry structure. The inclined support 35 strengthens the horizontal supporting force of the horizontal support 34, and the inclined tie rod 36 prevents the column from undergoing longitudinal deformation. The two together play a role in supporting and strengthening the basic gantry structure. It is easy to understand that multiple groups of the inclined support 35, inclined tie rod 36, column 32, and horizontal support 34 can be arranged between the upper longitudinal beam 33 and the lower longitudinal beam 31 as needed.
[0025] It should be noted that the appendixFigure 1 It is actually a schematic diagram of a better solution, including technical features such as structures and connection methods other than those described above. However, the embodiments of the present utility model can also be realized only through the above-mentioned essential technical features. Specifically, the horizontal support 34 is fixedly connected to the upper longitudinal beam 33, and it can be connected to the upper longitudinal beam 33 at both ends, that is, connected to different upper longitudinal beams 33 at both ends. Thus, only relying on the horizontal support 34, a basic gantry structure can be formed with the lower longitudinal beam 31, the upper longitudinal beam 33, and the column 32.
[0026] It is easy to understand that after the concrete lining formwork trolley moves to a specified position and height, the side form 12 needs to be moved to a specified position. In some embodiments, it can be realized by the combination of the side form oil cylinder and the lead screw: first, the side form oil cylinder jacks the side form 12 to the specified position, and then the lead screw fixes it. In other embodiments, the side form can also be moved to the specified position and fixed by other means.
[0027] In this way, taking the lower longitudinal beam, the column, the upper longitudinal beam, the horizontal support, the inclined support, and the inclined tie rod as components, a gantry with sufficient support strength is formed according to a certain connection method, thereby reducing the amount of gantry materials used and reducing the weight of the concrete lining formwork trolley. Further, the reduction in weight reduces the requirements for the vibration force intensity during the operation of the concrete lining formwork trolley, improves the quality of the tunnel wall after lining, and reduces the fuel expenditure, thus making a great contribution to the country's energy conservation and emission reduction. Finally, reducing the amount of gantry materials used reduces the production cost of the concrete lining formwork trolley.
[0028] Please continue to refer to Figure 1 , as shown in the figure, in some embodiments, the form 1 includes a top form 11 and a side form 12. The gantry 3 connecting the form 1 and the moving device 2 includes the horizontal support 34 fixedly connected to the top form 11. The gantry assembly further includes: a top column 37, one end of the top column 37 is fixedly connected to the horizontal support 34, and the other end is connected to the top form 11.
[0029] It is easy to understand that the top form 11 is provided with a grouting port 4, and the side form 12 is movably connected to the top form, which can specifically be a pin connection. The specific fixed connection method of the top column 37, the horizontal support 34, and the top form 11 can be a bolt connection.
[0030] On the one hand, the top form 11 is directly connected to the horizontal support 34 which is the top of the gantry, and on the other hand, the connection between the two is supported and strengthened by the top column 37. In this way, the gantry 3 and the top form 11 can be integrated into a whole, strengthening the stability of the concrete lining formwork trolley.
[0031] Please continue to refer to Figure 1, as shown in the figure, in some embodiments, the top column 37 is fixedly connected to the horizontal support 34 at the first connection point A, the inclined support 35 is fixedly connected to the horizontal support 34 at the second connection point B, and the straight line AB determined by the first connection point A and the second connection point B is perpendicular to the horizontal support 34.
[0032] In this way, the weight of the formwork and the cast-in-place concrete is transmitted to the horizontal support 34 through the top column 37, and the support is directly provided by the inclined support 35 connected to the lower longitudinal beam 31, thereby improving the support force of the gantry and avoiding the distortion of the horizontal support 34 under the misalignment force when the weight of the formwork and the cast-in-place concrete is too large.
[0033] Please continue to refer to Figure 1 , as shown in the figure, in some embodiments, the number of the horizontal supports 34 is an even number, and the gantry assembly further includes a horizontal beam 38, and the opposite ends of the horizontal beam 38 are fixedly connected to the horizontal supports 34 respectively.
[0034] Specifically, the fixed connection includes bolt connection.
[0035] 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 without changing other gantry components.
[0036] Please continue to refer to Figure 1 , as shown in the figure, in some embodiments, the concrete lining formwork trolley further includes:
[0037] A ventilation pipe 4, which is arranged in the gantry cavity.
[0038] The gantry cavity refers to the unoccupied space in the gantry 1. In a specific embodiment, the cavity space where the ventilation pipe 4 is arranged includes the space surrounded by the inclined support 35, the horizontal support 34 and the column 32 as shown in the figure.
[0039] In this way, it is avoided that the ventilation pipe is located near the formwork, which causes the operator to be unable to approach the formwork inspection window for vibrating operation, thereby further improving the lining quality.
[0040] It is easy to understand that generally only one ventilation pipe 4 needs to be provided for the concrete lining formwork trolley. Therefore, in some embodiments, as shown in the figure, the ventilation pipe 4 can be arranged in the cavity space surrounded by the inclined support 35, the horizontal support 34 and the column 32 on one side of the gantry 3, and the inclined support 35 can be arranged in the cavity space surrounded by the inclined support 35, the horizontal support 34 and the column 32 on the other side of the gantry, thereby further improving the stability and support force of the concrete lining formwork trolley.
[0041] Please continue to refer to Figure 2, as shown in the figure, in some embodiments, the mobile device 2 includes a wheel frame group 21, a transverse movement platform 22, and a lifting unit 23. The transverse movement platform 22 connects the wheel frame group 21 and the lifting unit 23 and is used for laterally moving the lifting unit 23. The lifting unit 23 is fixedly connected to the gantry 3.
[0042] The wheel frame group 21 includes wheels and a wheel frame and is used for moving the concrete lining formwork trolley along the track. The lifting unit 23 is fixedly connected to the gantry 3 and can specifically be bolt - connected to the lower longitudinal beam and is used for lifting the concrete lining formwork trolley. In some embodiments, the lifting unit 23 can specifically be a lifting oil cylinder. The lateral movement refers to moving the concrete lining formwork trolley in a direction parallel to the ground where the track is located.
[0043] In this way, due to the reduced weight of the concrete lining formwork trolley, the transverse movement platform 22 is directly arranged between the wheel frame group 21 and the lifting unit 23 under the gantry 3, enabling the lining trolley to quickly adjust its lateral position when there is a lateral position deviation. It can be seen that the concrete lining formwork trolley can move along the track and adjust the lateral deviation simultaneously, thereby improving the lining efficiency of the lining trolley. In addition, because the force is mutual, setting the transverse movement platform 22 in the mobile device 2 at the bottom of the gantry 3 reduces the center of gravity of the transverse movement platform 22, making the concrete lining formwork trolley more stable and not prone to tipping over during lateral movement.
[0044] Please continue to refer to Figure 1 , as shown in the figure, in some embodiments, the lining formwork unit further includes an inclined support unit 5. One end of the inclined support unit is pin - connected to the horizontal support, and the other end is pin - connected to the top form. In this way, the stability can be further enhanced and the supporting force can be provided.
[0045] Please continue to refer to Figure 2 , as shown in the figure, in some embodiments, the lining formwork unit further includes: a stay 6. The stay is fixedly connected to two adjacent top columns 37. The fixed connection includes bolt connection. In this way, the stability can be further enhanced and the supporting force can be provided.
[0046] Please continue to refer to Figure 2 , as shown in the figure, in some embodiments, the lining formwork unit further includes: a bottom column 7. One end of the bottom column 7 is fixedly connected to the lower longitudinal beam, and the other end is used for detachably connecting a jack. In this way, the jack can be installed during grouting to support the concrete lining formwork trolley with the jack, avoiding damage to the mobile device 2 due to excessive weight, thereby extending the service life of the concrete lining formwork trolley.
[0047] To facilitate the understanding of this solution, the lining process of the concrete lining formwork trolley provided by the embodiments of the present invention is summarized as follows:
[0048] In step S1, the wheel frame group 2 drives the concrete lining formwork trolley to move on the rail to the next working surface;
[0049] In step S2, the lifting unit 23 extends to lift the whole concrete lining formwork trolley to the designated position;

[0053] In step S6, the jack is installed on the bottom column 7 to support the concrete lining formwork trolley;
[0054] In step S7, finally, the concrete is poured outside the formwork trolley through the grouting port and vibrated until the concrete solidifies. The grouting port can be opened at the top form;
[0055] In step S8, the jack is removed, and then the main lifting oil cylinder descends. The wheel frame is lowered onto the rail, the lead screw is removed, the side form oil cylinder is contracted or removed, the side form is retracted, and then the trolley is moved to the next working surface by an external force to perform the next cycle.
